Description

Quick replacement roll device of calender Technical Field The utility model relates to the technical field of roller replacement, in particular to a device for quickly replacing rollers of a calender. Background The calender is a mechanical device for continuously calendering and forming materials through rotating rollers, and is widely applied to the production of sheets and films in the industries of rubber, plastics, metals and the like. The core component roller can generate surface abrasion, scratch or thermal fatigue under the working environment of high pressure and high temperature for a long time, so that the thickness of the product is uneven, the surface finish is reduced, and in addition, the production of products with different specifications is matched with the rollers with different roller diameters or surface textures. Therefore, the regular or on-demand replacement of the rollers is a key link for ensuring the product quality and adapting to various production, and the rollers need to be quickly replaced in order to improve the production efficiency, so that a quick roller replacing device of a calender is needed. According to the utility model, through searching, the limiting plate is arranged on the front surface of the knob, and when the roller body needs to be replaced, the limiting plate and the knob can be separated from contact with the limiting door by rotating the limiting plate and the knob, and the limiting door can be opened at the moment, so that a worker can pull out the bearing to detach and replace the roller body, the replacement difficulty of the roller body is reduced, the maintenance of the worker is facilitated, and the usability of the device is improved; The above-mentioned application is though can make limiting plate and spacing door break away from the contact through rotatory limiting plate and knob to open spacing door, thereby pull out the bearing, but this application can only be to the one end bearing of roll body pull out, and the other end still sets up in the portal frame, is inconvenient for changing the roll equally. Therefore, a quick roll-changing device of a calender is proposed to solve the above-mentioned problems.
