Automatic detecting safety protection device

Abstract

The invention discloses an automatic detecting safety protection device. The automatic detecting safety protection device comprises a balance block (1), a safety disc (2), a safety disc sliding base (3), a photoelectric switch receiver (4), a bracket (5) and a photoelectric switch emitter (6), wherein the balance block (1) is mounted in a groove of the safety disc (2); the safety disc (2) is mounted in a groove of the safety disc sliding base (3); the safety disc sliding base (3) is slidingly mounted on the bracket (5); the photoelectric switch receiver (4) and the photoelectric switch emitter (6) are respectively mounted at the upper and lower ends of the bracket (5); a boss (9) is arranged at one side of the safety disc (2); and a through hole (8) vertically penetrated is formed in the safety disc sliding base (3). The automatic detecting safety protection device enables an open mill to be automatically and quickly stopped under an overload condition after the safety disc is suddenly ruptured, so that equipment is not further damaged, and the danger is reduced.

Description

technical field [0001] The invention relates to an automatic detection safety protection device. Background technique [0002] When the mill is working, through two oppositely rotating rollers, under the action of friction, the rubber material piled up on the working surface of the rollers is pulled into the gap between the two rollers, and in this area The strong extrusion and friction will break the molecular chain of the rubber material and change the molecular structure, thereby increasing the plasticity of the rubber material and increasing the dispersion uniformity of the rubber material. [0003] When the mill is working, a large load is generated between the front and rear rollers. In order to prevent damage to key components such as rollers, frames, and bearings caused by excessive loads, a safety device is installed between the rollers and the frame. Device, the safety device is equipped with a safety sheet, which is made of brittle materials. When the equipment i...

Problems solved by technology

[0004] With traditional safety devices, after the safety sheet is broken, manual emergency parking is required. If the stop is not timely, it will cause further damage to the equipment, which is relatively dangerous. Factors affect the safety performance of the equipment and reduce the risk. We have developed an automatic detection safety protection device, so that the mill can be automatically and quickly stopped by detecting the control signal equipment after the load is overloaded and the safety sheet is broken.
