Steps to stop the bottle blowing machine
2021年1月27日 日常Steps to stop the bottle blowing machine
The rapid development of bottle blowing machine has replaced semi-automatic and has become the standard of the current era. Its operation is simple, without manual intervention, but there are still some precautions during the startup process and use, so what are the specific parking steps?
Close the feeding system of the bottle blowing machine and close the hopper blanking baffle. Drain the material in the barrel and shut down after the material is emptied. Turn off each auxiliary machine. Turning off the heaters, cooling water pumps, and lubricating oil pumps of each section will eventually block the main control power supply. Close each inlet pipe valve.
The blow molding machine operation mode is selected to the manual position to avoid the misoperation of the whole cycle and ensure the personal. Close the feed gate and stop feeding the material barrel. The needle seat is retracted, so that the nozzle is out of touch with the mold. Sort out the remaining material in the barrel, select repeated injection and pre-plasticization, until the material no longer appears and stops from the nozzle. At this time, the screw speed should be reduced, and the idling time should not be too long. Put all operation switches and buttons in the off position, cut off power and water.
The advantage of using the blow molding machine https://www.sunmolds.com/ to do the pre-blow molding process before the blow molding is the start-up operation of one-step extrusion and stretching. Whether the current indication value of each section of the heater is normal, after reaching the processing temperature, the constant temperature is 1-2h.
Regularly maintain the blow molding machine. If the equipment is used normally before, it is generally caused by the high ambient temperature, and the working environment needs to be cooled. In short, the correct method of operation is king.

What are the methods to improve the plasticization and extrusion of plastic machinery?
The effect of the machine in the hands of different technicians is different, which is not the same as the value of the same thing in the hands of different people. We can’t just take machine-based production for granted. During the production process, we will understand their working process, the operating conditions of the machine at each time period and the impact of various configuration materials on the performance of the machine. Only by grasping these principles can we call it Be professional.
Some plastic machines only use new primary color granular materials. When the recycled material exceeds 30% of the product ingredient ratio, the extrusion volume is reduced by 20% to 30%; in the product ingredient ratio, toner material When the amount is large, the extrusion volume is reduced by 50 to 60%. Taking into account that the extrusion efficiency is too low, the phenomenon of waiting for materials for a long time, resulting in a long cycle cycle, so no matter how good the other functions and performance of the blow molding machine are, it has seriously affected the production efficiency and caused the production cost to become higher. In particular, double-station hollow blow molding and large hollow blow molding machines require a lot of material storage and a long waiting time, so they cannot fully play their role. Use masterbatch particles in the raw materials instead of toner materials, the effect is better. But for blow molding machine users, the first is the high cost of using color master particles, and the second is that the hollow plastic products have a large variety of products and the unit quantity is small. It is impossible to use color master particles for each product instead of toner materials.
Improving the working performance of the machine is to create more benefits for the company. As every employee of the company, we must report this idea to work. As the earliest plastic machinery manufacturer in Zhangjiagang, we are here to assure all customers As long as we produce the machinery, we will not only guarantee that after-sales, I will also provide professional technical instructors to give technical guidance to the company so that the products can exert better performance. Create more value for the enterprise.
These points are summed up by our technology and hope to help you:
1. Due to the low extrusion efficiency due to the use of recycled materials and toner-containing product ingredients, which seriously affects the production of some products, it is recommended that blow molding machine manufacturers consider how to improve the use of toner-containing materials when developing blow molding machines. Plasticizing and extrusion capabilities of materials and recycled materials.
2. Optimize the flow channel structure of the die head: due to the dead angle of the structure of some flow channels, it is easy to cause two long stains on the parting line of the hollow blow molded product with low light color. When producing light-colored products such as primary colors, yellow, and milky white, it is required that there is no other coloring on the hollow blow molded products produced, and the inside of the machine head must be cleaned very clean. However, the total washing machine time is as long as 12-18 hours, sometimes even longer, and the time to remove stains is about 2/3 of the entire washing machine time, which greatly increases the washing machine color change cost. If you wash the machine frequently, it will be even more overwhelmed.

When people use various plastic products and equipment in their lives, especially the use of plastic bottles, they not only have good performance characteristics, but are also very convenient in use. Compared with glass bottles, they are not only bulky, small in size, and light in weight. , And will not appear to be broken, so it is widely used by people, and it is widely used in life or other areas. Most of these plastic bottles are made by blow molding machines, which mainly It is a kind of equipment that uses blow molding process to make plastic particles into hollow containers. Therefore, it is not only simple to use, convenient to operate, but also saves more time. The process of making plastic bottles in the blow molding machine factory:
1. First of all, the preform is irradiated by infrared high temperature lamp, which can better make the preform of the preform, but the preform mouth does not need to be heated, so that it can better maintain the shape of the mouth. Cooling equipment to cool down.
2. Once again, put the preheated preheated preform into the blow mold made before, and then stop high-pressure inflation on it, so that the preform can be blown and drawn into bottles of various shapes that people need, satisfying People’s needs.
Matters needing attention before using the blow molding machine
About the bottle blowing machine is mainly used to blow plastic bottles. It can blow plastic particles or preforms into bottles through certain craftsmanship, so that people can use various shapes of plastic in their lives. Bottles bring convenience. The blow molding machine mainly uses oil-free air bag clamping technology to stop the operation. Not only is the clamping force large, but the toggle work is less forced and has a long life. People should use the blow molding machine. How to operate it is easier and more convenient to use and extend the service life of the bottle blowing machine.
1. When people use the blow molding machine, they should carefully check whether the power supply, control system, heating system, etc. of the blow molding machine are in a normal state, and for the parts that need to increase the smooth oil, they need to increase the appropriate amount of smooth oil. Ensure the normal use and work of the equipment.
2. When using the bottle blowing machine, you should also accurately place the mold equipment on the bottle blowing machine. You should also carefully check whether the button can be in the correct position before, and you need to start, stop debugging or work in accordance with the requirements of the rules. Make sure that the machinery and equipment are working and working under normal conditions.

The automatic bottle blowing machine combines the two operations of bottle blowing through the operation of the manipulator, eliminating the need for the manual process of putting the preheated preform into the blowing mold. Greatly accelerate the rate of consumption, the process flow of the blow molding machine The blow molding process of the blow molding machine is a two-way stretch process, in this process, the PET chain is bidirectionally extended, oriented and arranged.
Thereby increasing the mechanical properties of the bottle wall, improving the tensile, tensile, and impact strength, and has a good air tightness. Although stretching helps to increase the strength, it should not be over-stretched. It is necessary to control the stretch-inflation ratio: do not exceed 3.5 to 4.2 times in the radial direction and 2.8 to 3.1 times in the axial direction. The wall thickness of the preform should not exceed 4.3mm.
Bottle blowing is stopped between the glass transition temperature and the crystallization temperature, and it is generally controlled between 90 and 110 degrees. In this interval, the PET is in a highly elastic state. It becomes a transparent bottle after rapid blow molding and cooling and shaping. The blow molding process includes: stretching-blowing once-blowing twice. The three actions have a short time, but they must be coordinated. Good, especially the first two steps determine the overall distribution of materials and the quality of blowing bottles.
Therefore, it is necessary to set the parameters: stretching start opportunity, stretching speed, pre-blowing start and end time, pre-blowing pressure, pre-blowing flow, etc., if possible, better control the overall temperature distribution of the preform, The temperature gradient of the inner and outer walls of the preform will induce stress in the bottle wall during the rapid blowing and cooling process.

Many beverages (including beer, sparkling wine, etc.) contain carbon dioxide co2, also called carbonated gas. Carbon dioxide is carbonic acid when it is soluble in water, which is very weakly acidic. Carbon dioxide is slightly soluble in water under conventional conditions, which means that it is very soluble. The amount of CO2 dissolved in the production of CO2 is greatly increased under pressurized conditions. The pressure of beer is generally higher than that of soft drinks, so Beer bottles are pressure vessels and have special specifications. No one has seen beer in plastic bottles. This is why beer bottles are more valuable than liquor bottles. Carbonated beverages such as cola use ordinary containers, which of course must be acceptable. pressure. What we call "shaking vigorously" actually changes the pressure balance in the container, forming a large amount of carbon dioxide gas to escape. When a good bottle of beer is opened, foam will be sprayed, and it is also because of changes in pressure that cause carbon dioxide to escape. Some people open the beer and see the spray and quickly cover it. This is dangerous. You can only hope that the beer bottle is fully qualified, otherwise it may explode. Of course, the increase in temperature will also reduce the solubility of carbon dioxide, causing the gas to escape.
Because beer contains organic ingredients such as alcohol, and the plastic in plastic bottles is organic. These organics are harmful to the human body. According to the principle of similarity and compatibility, these organics will dissolve in beer. When people drink such beer, they will also be toxic. Organic matter is ingested into the body, thus causing harm to the human body.
Beer bottles must be pressure-resistant and fresh-keeping due to the special nature of beer, so beer bottles are generally dark-colored bottles, and glass bottles have better fresh-keeping performance and pressure resistance than plastic bottles, so glass bottles are currently used. , Now there are plastic bottles (pet beer bottles), not many due to technical reasons. Of course pet is a safe and non-toxic plastic product. The company mainly produces automatic blow molding machines, plastic blow molding machines and other products, welcome to buy.
