Meltblown fabric extruderThe following operations may only be performed after the safety check has been completed and found to be correct:
(1)Engage the clutch, manually rotate the pulley to rotate the extrusion spindle4~5turns to check for any foreign objects falling into the equipment and whether there is any jamming phenomenon inside.
(2)For vacuum extruders, use the same method to check the mixing part.
(3)After checking that the above parts are correct, open the clutch. Only then can the main motor be started. If the extruder uses a forced lubrication oil pump, start the lubricating oil pump first, then start the main motor. After the main motor speed is normal, engage the clutch and let the entire equipment run empty1~2h。
(4)During idle operation, check whether each part of the machine is running normally, whether there is any abnormal sound, whether there is any abnormal temperature rise at each bearing part, and measure the no-load current of the main motor respectively. If any abnormality is found, stop the machine immediately and eliminate it.
(5)In order to facilitate the discharge of the new extruder, a proper amount of water can be poured into the feeding port before adding raw materials. For vacuum extruders, the inspection door of the vacuum chamber can be opened at this time, and raw materials can be added without starting the vacuum pump.
(6)When the raw material reaches the die head and begins to extrude outwards, open the clutch and stop feeding. Then install the die head and close the vacuum chamber inspection door.
(7)Start the vacuum pump. When the vacuum pump is a water ring type, the water supply valve of the vacuum pump should be opened before starting the vacuum pump, and adjusted to the specified flow rate.
(8)Engage the clutch and add raw materials evenly from the feeding port at the same time, and start extruding.
(9)After8hrunning under load, check whether all fasteners are loose to ensure vacuum and avoid equipment failure.
(10)During the above time, regularly measure the voltage and current values of the main motor; check the temperature rise of each bearing part and electrical components; check whether the vacuum chamber is well sealed, record the vacuum degree; check whether there are any abnormal phenomena in all moving parts and clutches; check whether the pressure and circulation of the forced lubrication oil are good. Stop the machine and eliminate any abnormal phenomena.
(11)Meltblown fabric extruderWithin100hafter the start of feeding, the feeding amount should not exceed60%of the rated output, to ensure that the machine has sufficient running-in time.
(12)When the extruder needs to be stopped, first stop feeding and close the water and gas valves of the stirring part of the vacuum extruder. Only when the extruder die head no longer continues to discharge materials can the clutch be opened, the vacuum pump and the vacuum pump water supply valve be closed, and then the main motor and lubricating oil pump motor be closed.
(13)When the extruder needs to be stopped for a long time, the raw materials in the extruder barrel, die head, and die should be cleaned immediately after stopping.

Summary of Experience with Failed Colin Column Balance Adjustment
Analyzing the causes of errors and summarizing lessons learned during work is an important way to improve work efficiency. Fault case: A Hetian injection molding machine's Collin column broke. The Collin column was replaced and the balance was adjusted, without needing any special tools.
Injection Molding Machine Accessories: Detailed Analysis of Common Temperature Problems!
Injection molding machine accessories. In co-ordinated control, the direction of the temperature sensor in the mold is critical. When placing the temperature sensor, the user must consider its shape, structure, and the direction of the cooling channels. In addition, the temperature sensor cannot be placed arbitrarily; it should be placed in an area that has a critical effect on the quality of the injection molded product. There are many ways to connect one or more high-temperature mold temperature controllers to the controller.
Injection Molding Machine Accessories: Standard Maintenance for Injection Molding Machines
Injection molding machine accessories. Everyone should formulate appropriate daily, monthly, and annual maintenance plans based on the condition of the equipment itself, and carefully implement them for each machine according to the plan. Before using the equipment every day, we should check whether each part of the equipment is normal, such as whether the machinery is working normally, whether the heating conditions of each part are normal, whether the circulating water pipes are leaking, whether the emergency stop button can cut off the motor power supply, etc.
What should be noted when repairing a faulty piston rod?
Piston rod failure is normal. The key is to pay attention to the precautions during specific maintenance. If non-professionals perform maintenance, many problems may arise. If possible, choose professional personnel. Maintenance efficiency and its own use value will be higher. We recommend that everyone should understand the following precautions when understanding piston rod maintenance.
What are some applications of piston rods?
In fact, even if we don't mention it, everyone should know quite a bit about piston rods. Of course, to ensure the efficiency of the piston rod, we must guarantee its performance and quality. If more friends are interested in this field, you can also Tel us to discuss your views, I believe this will be helpful to our work.
Connecting structure of piston rod and piston and how to choose piston rod
Piston rods offer significant advantages in practical applications, and the connecting rod structure of the piston is also unique. When used in combination, it is essential to carefully select hydraulic cylinders that demonstrate good operating and production performance. Such products will be highly reliable. The connection structure between the piston rod and piston, and the manufacturing method of the hydraulic cylinder with this piston rod, are essentially the same.
What does the mold pull rod spacing mean in the injection molding machine parameters?
The actual usable area of the template: the greater the distance between the ejector rods, the greater the actual width and height of the grinding tools that can be accommodated. Because injection molding machines need to install plastic injection molds between the moving template and the fixed template, plastic products can be processed. If the mold is to be installed between the two templates, it must pass through two adjacent ejector rods, so the shape of the mold must be smaller than the spacing between the ejector rods.
