The safety device of the mill and the method of replacing the safety gasket

Abstract

The invention discloses an open mill safety device and a method for replacing a safety gasket. The device comprises a safety gasket mounted between a distance adjusting screw and a bearing block; a T-shaped guide groove is formed in the bearing block; a first safety gasket seat and a second safety gasket seat which are capable of sliding along the T-shaped guide groove are mounted in the T-shaped guide groove; cambered grooves are formed on both opposite sides of the first safety gasket seat and the second safety gasket seat; the two cambered grooves are matched with each other to form a cavity; the safety gasket and the head of the screw both are located in the cavity, and the safety gasket is fixed to the head of the distance adjusting screw. According to the open mill safety device, when the safety gasket is damaged, the internal safety gasket seat for holding the safety gasket are capable of directly sliding toward two sides to be opened, such that the damaged safety gasket can be taken out, and after a new safety gasket is installed, the two safety gasket seats are just glided to the middle to be closed; the steps of demounting and mounting a flange and the safety gasket seats for a traditional safety device are omitted, and the time and cost of repair are greatly reduced.

Description

Technical field [0001] The invention relates to the field of open mills for rubber or plastic production, in particular to a mill safety device for protecting rollers, and a method for replacing safety gaskets. Background technique [0002] The open mill is a kind of rubber machinery used for plastics and rubber mixing or heat smelting and pressing. When it is working normally, there is a large transverse pressure between adjacent rollers. In order to prevent the failure of the open mill When the roller is enlarged, the roller is bent or even broken, and a safety device is provided in the pitch adjusting device of the open mill. The structure of the safety device in the prior art includes: a safety washer seat fixed on a bearing seat by screws, a flange composed of two halves is arranged on the upper part of the safety washer seat, and the flange is connected to the safety washer seat by screws, A safety washer is arranged inside the safety washer seat, and the safety washer is ...

AI Technical Summary

Problems solved by technology

[0003] The safety device of the mill with the above structure has the following disadvantages: when replacing a new safety gasket, it is necessary to disassemble the flange and the safety gasket seat fixed on the bearing seat before the damaged safety gasket can be taken out and installed. When installing a new safety gasket, install all the flange and safety gasket seat

Since the flange and the traditional safety gasket seat are connected by multiple screws, it is time-consuming and laborious to disassemble and install, which is very inconvenient
