Control system of vacuum plastic-absorbing machine

Abstract

The invention discloses a control system of a vacuum plastic-absorbing machine. The control system comprises an automatic forming mechanism control system and an electric furnace temperature control system which are arranged in the same operating platform; and a switching key for switching the electric furnace temperature control system and the automatic forming mechanism control system is arranged on the operating platform. The electric furnace temperature control system comprises an intelligent temperature control module, a temperature compensation module and a communication module. The two control systems are subjected to resource optimization and integration, and the electric furnace temperature control system is integrated into the automatic forming mechanism control system, so that the occupied area of the operating platform is reduced. Moreover, the system adopts the intelligent temperature control module, the temperature compensation module and the communication module, so that temperature can be intelligently and effectively controlled, constant temperature control is realized, the uniformity of heat energy is good, and heat is emitted uniformly.

Description

technical field [0001] The invention relates to a control system, in particular to a control system of a vacuum suction molding 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] At present, the automatic forming mechanism control system of the blister machine and the electric furnace temperature control system are two independent operating platforms, which occupy the space of the machine, bring some inconvenience to the production operation, and increase the company's cost investment; In the existing temperatu...

Problems solved by technology

[0003] At present, the automatic forming mechanism control system of the blister machine and the electric furnace temperature control system are two independent operating platforms, which occupy the space of the machine, bring some inconvenience to the production operation, and increase the company's cost investment; In the existing temperature control system of the blister machine, a system similar to the "on-off" device is adopted; that is, when the system is turned on, the temperature rises, and when the temperature rises to the specified temperature, the system is turned off; when the temperature is lower than the specified When the temperature is high, the system is turned on again to heat up; such a cycle of opening and closing not only wastes power and shortens the service life, but also has a large error in temperature control accuracy.
