Embodiment 1

[0026] As a preferred embodiment of the present invention: the frequency converter in step 1 is based on frequency conversion technology and microelectronics technology to change the AC frequency of the power supply to control the servo motor operation, and the model of the frequency converter is S7-1500PLC, and the frequency converter replaces manual adjustment. When the motor is adjusted, it is more precise, has the advantages of fast response and precise adjustment, and reduces manual participation in the process, reduces labor costs, and reduces waste of raw materials, making the probability of waste products lower.

Embodiment 2

[0028] As a preferred embodiment of the present invention: the speed reducer in step 2 plays the role of matching speed and transmission torque between the servo unit and the rotating shaft, and the speed reducer is composed of a transmission gear and a worm, which is convenient for the speed reducer to reduce the transmission speed of the servo motor. Speed, to prevent waste products caused by too fast servo motor speed.

Embodiment 3

[0030] As a preferred embodiment of the present invention: the rotating shaft in step 3 is connected with the transmission gear in the reducer through the connecting gear, the connecting gear is meshed with the transmission gear in the reducer, and the speed of the servo motor is related to the transmission in the reducer After the gear is connected to the worm, the rotating speed has been reduced, and the transmission gear transmits the reduced rotating speed to the connecting gear, and the connecting gear can drive the rotating shaft to rotate.

Abstract

The invention discloses a pull-tab system of a vacuum suction molding machine. Through steps 1, 2, 3, 4 and 5, a frequency converter controls a servo motor to operate, the frequency of power supply alternating current of the servo motor is controlled by the frequency converter to achieve the purpose of adjusting the operation of the servo motor, the servo motor drives a speed reducer to operate, the rotation speed of the servo motor is reduced by the speed reducer to a certain extent, and then the reduced rotation speed of the servo motor is transmitted to a rotating gear, the speed reducer drives the rotating gear to rotate, the rotating gear drives a driving panel through a driven gear and a chain to move, and the driving panel can drive raw materials to move. According to the pull-tab system, manual adjustment is replaced by the frequency converter, so that the servo motor can be more precisely adjusted; the pull-tab system has the advantages of quick response and accurate adjustment, reduces manual participation in the process, the labor cost and the waste of raw materials, and reduces the probability of waste product.

Description

technical field [0001] The invention relates to the field of plastic suction machines, in particular to a pull-tab system of a vacuum plastic suction machine. Background technique [0002] Blister molding machine (also called thermoplastic molding machine) is a machine that absorbs heated and plasticized PVC, PE, PP, PET, HIPS and other thermoplastic coils into various shapes of advanced packaging and decoration boxes, frames and other products. Using the vacuum suction generated by the vacuum pump, the heated and softened thermoplastic sheets such as PVC and PET are molded into various shapes of vacuum covers, blister trays, blisters, etc. through molds. [0003] However, currently used in the pull-tab system of the vacuum forming machine, the servo motor needs to be manually adjusted, which may easily cause the servo motor to run too fast or too slow, and cannot be adjusted accurately, resulting in defective products. Contents of the invention [0004] The purpose of th...
