1. Speed control type glue machine.
This type of glue machine is characterized by constant pressure and temperature and adjustable speed. The pressure between the rubber roller and the plastic sealing temperature have been set at the factory. The plastic sealing speed can be adjusted by the user and the speed regulating glue machine with two adjustable temperatures can be set. The sealing fastness of the document is controlled by the plastic sealing speed. In fact, the adjustment speed is also to change the molding temperature. Fast speed, short heating time, low plastic sealing temperature, slow speed, long heating time and high plastic sealing temperature. The operation of such models should also be carried out one by one according to the procedures required by the process. If the speed is too fast, it will cause the document to be heated too low during the sealing process, and the opening speed will be too slow, and the heat will be supplied too much, which will cause the deformation of the document after sealing and overflow. The pressure of the speed-regulating type of glue machine also has a certain adjustable range, and if necessary, it can be fine-tuned according to the instructions.
2, temperature-controlled type of glue machine.
This type of glue machine is characterized by constant pressure and speed and adjustable temperature. The pressure between the rubber rollers and the running speed of the rubber roller are fixed at the factory, and the plastic sealing temperature can be adjusted by the user. The sealing fastness of the document is controlled by the plastic sealing temperature. Since the structure of the glue machine varies from manufacturer to manufacturer, the temperature displayed on the glue machine is not necessarily equal to the mold temperature. Generally, the glue machine heated by the front rubber roller is used, and the display temperature is close to the plastic sealing temperature. The operation of this type of machine should be carried out one by one according to the procedures required by the process. When the pressure and speed are constant, the temperature is too low and the plastic seal is not strong. When the temperature is too high, deformation and overflowing occur. If the pressure between the rubber rollers is too large, it is easy to overflow. If the temperature is repeatedly adjusted and still can not meet the plastic sealing requirements, the pressure of the model has a certain adjustable range. Refer to the product description to unload the cover and make appropriate fine adjustment to meet the plastic sealing conditions.
