[0002] Feeding equipment is widely used in industrial production, and inspection doors play an important role as the main channel for observation, inspection and maintenance. Existing inspection doors are mainly mechanical and electric. Mechanical inspection doors are simple to maintain, cumbersome to use, and the mechanical transmission pressure is insufficient, which can easily cause material leakage. The pressure of electric inspection doors is relatively stable, but the failure rate is high, the later maintenance is troublesome, and the safety performance is poor. In addition, both mechanical inspection doors and electric inspection doors require sealing gaskets, which need to be replaced regularly, and the sealing effect is unstable, especially in high temperature, corrosion and other environments. Later inspections and replacements are relatively frequent, causing inconvenience in use. Therefore, in the case where the inspection door needs to be opened or closed frequently during the inspection and maintenance of the feeding equipment, it is very necessary to study a new inspection door that can solve the problems of dust leakage caused by loose sealing and inconvenience in operation caused by complex control mechanism design.
