Sanding machine brake protection device and sanding machine

Abstract

The invention discloses a brake protection device for a sanding machine. The brake protection device comprises a brake pad, a brake air cylinder and an air pipe connector, wherein the bottom end of the brake air cylinder is connected with one end of the air pipe connector, a sensor is positioned at the upper end of the brake air cylinder, a pressure switch is positioned on the air pipe connector, and the brake pad can cane generated pressure to the sensor and the pressure switch through the brake air cylinder and switches motion signals of the sensor and the pressure switch into a control system of the sanding machine. Alarm information is controlled by programs to be sent out. In addition, the invention further provides a sanding machine with the brake protection device. By means of the method, the brake protection device for the sanding machine and the sanding machine can grasp position change of a brake device and pressure change of the pressure switch to timely provide running conditions of the brake device for an operator and improve equipment reliability and equipment safety.

Description

technical field [0001] The invention relates to the technical field of wood-based panel production, in particular to a brake protection device for a wood-based panel sander and a sander using the brake protection device. Background technique [0002] In the wood-based panel production line, sanding equipment is used to perform post-sanding treatment on the produced MDF, particle board, etc. For the surface flatness of the processed products, it is necessary to meet the customer's use in different occasions and the requirements for the quality of the board surface. The sanding machine is equipped with multiple sets of sanding drums, on which are installed various types of abrasive belts for sanding the surface of the board. The moment of inertia of the drums is set relatively large, in order to keep the abrasive belts at a constant speed during the sanding process. , to ensure the quality of the board surface. Because the moment of inertia of the sanding drum is very large, ...

AI Technical Summary

Problems solved by technology

In summer, the high temperature causes a large temperature rise around the equipment. The pneumatic compressed air pipe of the brake device often bursts suddenly due to high temperature, causing the device to malfunction. Since there is no protection device, it is difficult for the operator to find out. The sanding drum is still driven by a large motor. Drive operation, the brake pads generate brake sparks and are quickly worn out. Due to the large amount of sanding dust generated by the sander during the production process, it is also sucked away by the fan near the brake device. The sparks and sanding dust are likely to cause combustion or explosion.

This situation, on the one hand, will cause wear or damage to the brake device of the equipment, on the other hand, it will constitute a major fire or explosion safety hazard
