What is the plastic machine?In fact, we often see it in our daily life. It will be equipped in Wenyin stores, photography shops and other places.So what is the use of plastic sealing machine?What are the common classification?Let me introduce you below!
What is the plastic sealing machine
Plastic sealing is a polytic membrane with hot -melt glue. The sealing items are bonded inside the plastic film through the processing of the glue machine. Because the processing process is performed at a certain pressure and high temperature, and the height is high, the height is highThe hot melting glue with good quality polyclic membrane and perspective.Therefore, at normal temperature, it can not only ensure that the plastic items are not destroyed, but also increase the intuitive effect of the items.In this process, the technical performance of the glue machine is an important factor to ensure the quality of the plastic seal.
Common classification of plastic seal machines
At present, the glue machine in the Chinese market can be divided into two types: temperature adjustment and speed -regulating.
1. Temperature -adjustable overlapping machine: The characteristics of this plastic machine are that the pressure and speed have been fixed.The temperature can be adjusted.The pressure between the rubber roller and the running speed of the rubber roller have been fixed when they leave the factory, and the plastic sealing temperature can be adjusted by the user by itself.The sealing of the document is controlled by the plastic seal temperature.Due to different manufacturers due to different manufacturers, the temperature displayed on the plastic seal does not necessarily equal to the plastic seal temperature.Generally, the plastic sealing machine heated by the front rubber roller is relatively close to the plastic seal temperature.The operation of such models should be carried out in order of procedures required by process.When the pressure and speed are certain, the temperature is large and the shaping is not firm. If the temperature is too high, it will deform and spill the glue.The pressure between the rubber roller is too high and the gum is prone to occur.If the temperature is repeatedly adjusted, it is still not possible to meet the requirements of the plastic seal, the pressure of the model can be adjusted, and the product can be explained by the product to explain the unloading cover and fine -tuning to meet the best plastic seal conditions.
2. Speed ??-regulating gel machine: The characteristics of this plastic machine are that the pressure and temperature have been fixed and the speed can be adjusted.The pressure and plastic seal temperature between the rubber roller have been adjusted when they leave the factory. The plastic sealing speed can be adjusted by the user by themselves.The sealing of the certificate is controlled by the plastic seal speed.In fact, the adjustment speed is to change the plastic seal temperature.Fast speed, short heating time, low plastic seal temperature, slow speed, long heating time, and high plastic seal temperature.The operation of such models should also be performed in accordance with the procedures for process requirements.If the speed is too fast, it will cause the insufficient heating during the seal and cause too slow the speed of the glue. Due to excessive heat supply, the seal deforms and spill the gum.The pressure of speed -type plastic seal also has a certain range of adjustment. If necessary, you can refer to the instructions to make appropriate fine -tuning.
Plastic sealing method
There are two types: heat plastic and cold plastic.
Thermoplastics uses multi -segment temperature control, and the rolling heating method generates a high temperature to set the plastic seal and data page for shape.
Cold plastic uses viscous or magnetic plastic film to set the plastic film and data page without heating.
