Pulse-heating hot press for light guide plate production

Abstract

The invention relates to the technical field of electromechanical equipment, in particular to a pulse-heating hot press for light guide plate production. The hot press comprises a press body, a fixingplate is fixedly mounted at the top of the body; two groups of electric sliding tables are fixedly installed at the positions, close to the middle end and the right end, of the top face of the fixingplate. A workpiece placing plate is fixedly mounted on sliding blocks assembled at the middle ends of the two groups of electric sliding tables through welding; a portal frame is arranged on the topsurface of the fixing plate; the lower ends of the left and right sides of the portal frame are fixedly welded to the left and right ends of the top surface of the fixing plate. According to the pulseheating hot press, a pulse transformer capable of achieving frequency modulation and pulse heating is adopted, and multi-stage temperature rise control over the hot pressing outer barrel can be achieved; and through the arranged temperature sensor, the heating temperature of the hot-pressing roller is read, the temperature value is output to the display screen through the PLC for real-time temperature curve display.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to a pulse heating heat press machine for light guide plate production. Background technique [0002] When processing the light guide plate, it is necessary to use pulse hot pressing equipment to heat the light guide plate. The pulse hot press uses a transformer to generate a low voltage and high current, which makes it heat rapidly through the welding head. However, the structure of the heat-pressing part in the general heat-pressing machine is relatively small, which is not suitable for processing large-sized light guide plates. [0003] For example, a pulse heat press with the Chinese patent application number CN201620045687.5 includes a frame, the bottom of the frame is a host, the top of the frame is a monitoring device, the middle of the frame is an operating platform, and the host includes a control box And air source components, the monitoring device inc...

Problems solved by technology

[0004] Although the above-mentioned invention can be provided with multiple processing stations, the structure of the hot-pressed components is small, and it is impossible to carry out hot-pressing processing on the large-sized light guide plate as a whole. It will affect the effective precision of light guide plate processing, so it is urgent to develop a pulse heating hot press for light guide plate production to solve the above problems
