Shutdown Turn off the main power switch, and then turn off each part of the power switch.

Precautions for operation of casting film machine

The casting film machine uses particles about the same size as rice, which can be ground, heated and melted during operation. The plastic film is made according to the required size, and the finished product is evenly colored, clean, and the bag is well stretched. What are the operating precautions for the downstream film spreading machine? When operating the casting film machine, it is not allowed to stand directly in front of the machine to avoid accidental injury to operators. Strictly prevent metal impurities, small tools, and other solid objects from entering the raw material during feeding, which may fall into the material barrel and damage the machine. Do not wear gloves when operating the casting film machine to avoid injury. Then there is the inspection and addition of lubricating oil for the reducer and air compressor, as well as the inspection of the lubrication of the transmission machinery. Avoid dry operations to avoid damaging the machine and generating noise. When connecting, it is necessary to first check the power cord for any breakage or leakage, and check if there is any abnormal damage to the casting film machine. Before starting the machine, confirm that all components are normal and standardized to avoid affecting production and causing accidents. Especially within the limitations of film forming conditions, increasing the film forming temperature, cold air temperature, and air filling rate will increase the turbidity of the paint film and reduce its glossiness, otherwise it will increase. When the material to be used appears uniform from the rod, wear gloves and slowly pull the tube blank. At the same time, close the empty end of the pipe, gently insert the air inlet control valve, put a small amount of compressed air into the spindle hole, and then carefully pass the foam stabilizer and herring plate. Before winding, use the drag roller and guide roller (if embossing is required, use the embossing roller). The casting film machine can be cleaned with a copper knife, copper rod, or compressed air, but be careful not to damage the smooth surface of the screw and screw. In addition, it is necessary to check whether the installation work of the casting film machine unit is carried out as required and whether the bolts are installed correctly. Check and add lubricating oil to the gearbox and air compressor, and check the lubrication of various parts of the mechanical transmission. I suggest that everyone also check the power and electrical components, and all parts should be securely grounded. Especially if there is no plastic inside the barrel or if the temperature does not meet the requirements, it is strictly prohibited to ignite. Check that there are no foreign objects in the raw materials, and no unqualified substances such as iron filings should be mixed in the raw materials. Alternatively, the material may need to be dried, otherwise it must be dried first. Check if the heating system and temperature measurement system of the unit are in good condition. Of course, during the start-up process of the casting film machine, unrelated personnel must leave to prevent the material from overheating, prevent the belt and mixing cylinder from being punctured, and prevent hair and clothing from getting entangled. During the ignition process, unrelated personnel should leave to prevent the belt from being punctured and prevent hair and clothing from getting entangled.

What are the uses of casting film machines?

The function of the casting film machine is to divert and recombine the melt, further soften and mix it, in order to improve the dispersion and uniformity of the mixing system. Adjust the appropriate melting pressure, remove gas from the material, increase the density of the melt, and prevent the formation of pores and pores in the film. Alternatively, in production, there are performance requirements for the screen changer. The cast film product has multiple functions, high requirements, and strict processing conditions. Only a screen changer can meet the needs of production. In fact, it can remain unchanged at room temperature, but it will shrink after heating. The barrel and screw are made of alloy steel and undergo nitriding treatment. The casting film machine has good hardness and corrosion resistance. The auxiliary machine is equipped with a working platform for easy operation and is equipped with a fixed bubble ring. Especially when the equipment is working, the winding device adopts double winding and cutting, and its power adopts a torque motor, which can maintain appropriate tension, tidy winding, and convenient roll changing. The casting film machine is now mainly used for blowing PLA, PBAT, PVA water-soluble biodegradable plastic films. Widely used in liquid packaging, printing lamination, clothing and textile packaging, industrial product packaging, etc. Compared to one layer, the bag is stronger and comes in two colors. In fact, the film produced by the casting film machine has excellent heat sealing performance and excellent transparency during operation, making it one of the main packaging composite substrates. Used for producing high-temperature cooking films, vacuum aluminum plating films, etc., the market prospects are very broad. Moreover, in recent years, with the development of domestic casting machine production equipment, some technical indicators have reached international advanced levels. Therefore, the threshold for entering production is getting lower and lower. As a result, some enterprises are rushing to introduce casting film production lines in order to achieve one-step success, pursuing higher quality while disregarding market demand and investment returns. This can cause huge resource waste. Therefore, the casting film machine is widely used for packaging textiles, flowers, food, and daily necessities.
