Method and device for film squeezing machine to automatically adjust film squeezing temperature according to motor temperature

Abstract

The invention relates to a method and a device for a film squeezing machine to automatically adjust film squeezing temperature according to motor temperature. The device comprises a control part, a setting / altering part, a motor, a heating part, a heating roller and a temperature sensor. In the device, a motor speed sensor is additionally arranged on the main control circuit of a microcontroller of a SCM (Single Chip Microcomputer) for sensing the speed of the motor at any time. The set temperature of every gear position of the film squeezing machine is correspondingly adjusted by judging the speed of the motor in the control main program of the microcontroller of the SCM so as to obtain an optimum matching between film-squeezing temperature and the squeezing speed for greatly improving the film-squeezing quality of the product; and therefore, the film squeezing effect of the film squeezing machine is greatly improved without carrying out AC (Alternating Current) MOTOR speed adjustment, and the problem of poor quality of film squeezing caused by the change of the speed of the motor because of different speeds of the motor is solved just by adding the motor speed sensor.

Description

technical field [0001] The invention belongs to the technical field of laminators, and more specifically relates to a method for automatically adjusting the set temperature of a laminator according to the speed of a motor and equipment thereof. Background technique [0002] The lamination quality of laminating machine mainly depends on three elements: speed, temperature and pressure. Under the condition of a certain pressure of the same lamination machine, if the lamination temperature can be adjusted accordingly with the change of lamination speed to achieve the best match between lamination temperature and speed, then the lamination quality will be greatly improved.

AI Technical Summary

Problems solved by technology

[0003] However, because the speed adjustment circuit of the AC motor (AC MOTOR) will be more complicated to implement, and the cost will also be increased due to the addition of the speed control circuit, so the speed of the traditional film laminating machine using the AC motor (AC MOTOR) as the speed output is average. It is non-adjustable, just adjust the temperature manually according to the thickness of the laminated film and paper

[0004] Because the traditional laminator uses AC motor (AC MOTOR), one of the characteristics of using AC motor (AC MOTOR) is that its film lamination speed will change with the change of power frequency, that is, the high power frequency, its lamination speed is fast , correspondingly, the power frequency is low, and the laminating speed is slow

In this way, for users who have different frequency power sources in the same area, when using the laminating machine, there will be a problem of poor laminating

The setting temperature of each gear of the laminator is generally fixed. If the setting temperature in the program is set according to the speed of the low-frequency power supply, the effect of laminating the film will be better when using the low-frequency power supply. When using a high-frequency power supply, the film lamination effect will appear low-temperature phenomenon due to the faster motor speed, such as lax edge sealing, whitening of the diaphragm surface, etc.; High temperature phenomena, such as wavy lines on the laminated film, bubbles on the surface of the diaphragm, etc.

Conversely, if the set temperature in the program is set according to the speed of the high-frequency power supply, high or low temperatures will also appear, which has become a major problem in the film laminating machine industry

[0005] Moreover, the power frequency used in each country is not the same. The traditional laminator must adjust the MCU microprocessor program of the control department of the laminator according to the power frequency of each country. Therefore, the MCU of the machine exported to each country Microprocessor control is not the same

In the parts management of the production process, every process from procurement to export is relatively cumbersome
