Refining machine and its distance adjustment device

Abstract

Disclosed are a space adjusting device and a refining machine comprising the space adjusting device. The space adjusting device is used for adjusting the space between different rollers (1) of the refining machine, the device comprising a hydraulic motor (3) provided on a machine frame (2) of the refining machine, a worm (4) connected to the hydraulic motor (3) so as to transfer the power output from the hydraulic motor (3), and a worm gear (5) matching the worm (4) and connected to a roller bearing housing of the refining machine. In comparison to a manual space-adjusting device of the prior art, the space adjusting device does not need to operate manually but rather to be driven hydraulically such that the operation process is simpler and the operating efficiency is also improved. In comparison to an electrical space-adjusting device, the structure of the hydraulic device is simpler, and it is not necessary to utilize a large power electric motor with a relatively large volume and a relatively complex transmission mechanism, and therefore the aesthetic appearance of the refining machine is also improved.

Description

technical field [0001] The present invention relates to the technical field of rubber machinery, and more specifically, relates to a distance adjusting device, and also relates to a refiner with the above distance adjusting device. Background technique [0002] Refining machine is a kind of main equipment for processing regenerated rubber. It is equipped with a plurality of rollers that contact each other. The surface of the roller is smooth and drum-shaped. When the refining machine is working, it can make the rubber after high temperature The rubber powder enters between the two rollers, so that the two rollers perform high-speed shearing and thin pass on it, and then squeeze the impurities in the rubber powder from the middle part of the roller to the two ends of the roller, so that the impurities Gather on the edge of the film formed by the regenerated rubber, and then use a scraper to remove the impurities on the edge of the film, and finally make the regenerated rubber...

AI Technical Summary

Problems solved by technology

[0003] In the actual production process, it is necessary to frequently adjust the distance between the rollers to meet the requirements of various rubber mixing processes. There are two kinds of distance adjustment devices used to adjust the distance between the rollers in the prior art, one is manual distance adjustment device, when it is necessary to adjust the distance between the rollers, the operator needs to manually turn the runner set on the frame of the refiner, and drive the movement of the roller bearing seat through the transmission mechanism connecting the runner wheel and the roller bearing seat, and then drive The rollers arranged on the roller bearings move to achieve the purpose of adjusting the distance between different rollers. However, since the rollers on the refiner are large and heavy, it is very difficult for the operator to rotate the runners. It is time-consuming and labor-intensive, which not only affects the work efficiency, but also greatly increases the workload of the operator; another distance adjustment device is an electric distance adjustment device, which also needs to drive a larger and heavier roller to move, so a high-power The electric motor is used for driving, which makes the electric distance adjustment device not only larger in size, but also more complicated in transmission structure, which is not conducive to the normal maintenance and repair of the refiner, and also greatly affects its appearance.
