Tooth-roller crusher

Abstract

The present invention discloses a tooth-roller crusher. The tooth-roller crusher is provided with a material feed inlet, tooth rollers and a roller spacing adjustment device. The tooth-roller crusher is characterized in that the tooth-roller crusher is provided with the four tooth rollers, wherein the first tooth roller (1) and the second tooth roller (2) are the roller couple, the third tooth roller (3) and the fourth tooth roller (14) are the roller couple, and the rolling match is formed between the second tooth roller (2) and the fourth tooth roller (14); a nut of the roller spacing adjustment device comprises two parts of a front nut (12) and a rear nut (13), wherein the two parts are connected by using a pin (5), the front nut (12) is fixed, the tail end of the rear nut (13) is provided with external threads, and the position of the external threads is provided with a round nut (15). The prominent characteristic of the tooth-roller crusher of the present invention is that: the three crushing operations are completed in the one device, such that the workload of the one device of the present invention is the workload of the three devices so as to substantially improve the production efficiency. In addition, in the adjustment device, the rear nut can move forward by turning the round nut, and the front nut is fixed, such that the radial gap between the screw and the nut is reduced, the screw is prevented from movement so as to provide high stability; meanwhile, the gap is reduced, such that the uncontrollable error is removed so as to improve the assembly accuracy.

Description

Technical field: [0001] The invention relates to a toothed roller crusher, which is used for pretreatment of granular oil in the process of oil production. Background technique: [0002] The crusher usually includes two toothed rollers driven by the main shaft, which crush soybeans, peanuts and other granular oils through shearing and extrusion. One existing crusher can only be crushed once, and the production efficiency is low. The production of finer particles requires repeated crushing, and multiple crushers work at the same time, occupying a large area of ​​space. The roller spacing adjustment device of the existing crusher adjusts the distance between the two rollers through the trapezoidal thread transmission of the screw and the screw nut. When the screw and the screw nut are used together, the radial gap between the two will gradually increase after long-term wear. Large, resulting in radial movement of the screw, and the amount of movement will increase day by day...

AI Technical Summary

Problems solved by technology

The roller spacing adjustment device of the existing crusher adjusts the distance between the two rollers through the trapezoidal thread transmission of the screw and the screw nut. When the screw and the screw nut are used together, the radial gap between the two will gradually increase after long-term wear. Large, resulting in the radial movement of the screw, and the amount of movement will increase day by day

In addition, due to the inability to eliminate the gap between the wire post and the wire mother and the accumulated errors in the assembly process, the two rollers collide and damage the quality of the roller surface when there is no material entering.
