Why do we need to maintain the plastic pelletizer?

Plastic pelletizing machine from the day it is put into production work, to bear a variety of power load. Due to work transmission wear, melt and decomposition gas corrosion, environmental pollution and operating errors, etc., its equipment performance and work efficiency are subject to change or a slight decline after some time. Maintenance of equipment to maintain its performance and production efficiency in a more extended period in a normal state improves economic efficiency.

How to efficiently maintain the plastic pelletizing machine?

The maintenance of plastic granulators can be divided into daily work maintenance and regular (monthly, quarterly, annual) maintenance.
Plastic granulator daily maintenance is the plastic pelletizing machine's everyday production work in each production shift operator maintenance inspection of the plastic pelletizing machine. Such as after the shift, add lubricant to the equipment, tighten the loose nuts, and scrub the equipment on the oil and other work. These tasks are also part of the plastic pelletizing machine operating procedures, so the plastic granulator operators carefully implement the operating systems. According to the production operation sequence requirements, it is one of the better maintenance of equipment content.

Plastic pelletizing machine routine maintenance focus

①. Often check the quality of the pure method of using raw materials, not allowed to have the grain, metal powder and other foreign matter wet into the raw materials into the machine Jane.
②. Regularly check the lubrication parts, fill the lubricating oil, and bear parts should not exceed 50 ℃ when the temperature rises.
③. Machine briefly has enough heating constant temperature time, do not allow the raw materials below the process temperature conditions to start production.
④. Screw work, start at low speed, work for some time, all average career before lifting off the screw speed.
⑤. No raw materials in the barrel, do not allow the screw airlift for a long time, the screw airlift time is not allowed to exceed 2-3min.
⑥. Often observe the screw drive motor ammeter pointer swing changes, such as a more extended period (allowing instantaneous overload) motor overload work, should immediately stop. Find the cause of the fault, and then continue production after the spot is removed.
⑦. After the barrel is heated to the process temperature for the first time, the bolts connecting the machine and the machine base should be tightened again.
⑧. When installing the mould and screw, the contact surface of the parts should be clean and free of any foreign matter. When disassembling, do not use a heavy hammer to hit the surface of the details; if necessary, it should be padded with hardwood, using a clock to hit the hardwood to disassemble the parts.
Note: When removing the residual material from the machine, screw and mould, only use the bamboo and copper knife brush to shovel the material, do not use the pot knife to scrape the sticky material, and do not allow the screw to clean up the residual material on the screw by grilling it with fire.

Plastic pelletizing machine regular (monthly, quarterly) maintenance focus

①. Newly put into production use of the plastic pelletizing machine, the test production time of 500h, to replace the new lubricant, exclude the old fat; cleaning the filter, oil pipeline, oil cup and oil tank, and then refill the new grease to the required amount of oil.
②. The wear condition of DC motor carbon brushes should be checked once a month and replaced when necessary.
③. Clean and blow away the dust and dirt in the electric control box every quarter.
④. Check the oil quantity in the lubricating oil tank once a quarter (month), and add enough oil to reach the required oil quantity in time.
⑤. Plastic pelletizing machine downtime longer, plastic pelletizing machine each major zero part (barrel, screw and mould, etc.) to protect against corrosion, pollution, heavy pressure, and other measures.
⑥. plastic granulator screw, barrel, head: mould production in each change of material. Must be cleaned once the auxiliary part (downstream equipment), please also fill the oil promptly, clean the dust.

Plastic pelletizing machine annual maintenance focus

①. Check the V-belt drive in the V-belt and pulley eagle damage, and adjust the V-belt drive center distance. Make the V-belt elasticity appropriate; wear a serious V-belt to be replaced.
②. Exit the screw, check the wear and tear of the machine simple and screw. For light scratches or the emergence of rough surfaces, use oil stone or fine emery cloth to repair and grind to achieve flat and smoothness: Record the actual size of the machine's inner hole and outer circle simple and screw.
③. Disassemble the gear reducer, bearing gland, check the quality of lubricating oil and the content of metal powder in the oil, clean the lubrication parts if necessary, and replace the filtered lubricating oil.
④. Check the wear of transmission gears and rolling bearings; the gears with more severe wear should be mapped. According to the need, put forward the manufacturing and purchase plan of spare parts, and prepare for the next maintenance into a replacement.
⑤. Check and correct the heating temperature (measured by mercury thermometer) of the machine simple and moulding mould and the difference of temperature value displayed by the instrument on the control box to ensure the correct operation of the process temperature.
⑥. Adjust and test the safety alarm devices to check the accuracy and reliability of their work.
⑦. Test and check whether the water, gas, and oil pipelines are smooth, clean, and repair the leaking and blocked parts.
⑧. Check and adjust the working position of the electric heating device, cooling fan and safety cover. Ensure that they can work usually and effectively.
⑨. Record the specifications of oil seal, bearing and V-belt, and propose spare parts procurement plan.
