A high precision draw roller

Abstract

The invention discloses a high-precision drawing roller, which comprises a bearing base, a lifting mechanism, a motor, a first connecting shaft, a belt, an electric telescopic rod and a second connecting shaft. The first connecting shaft is rotatably connected to the left side. On the support plate, the second connecting shaft is rotatably connected to the left side of the bottom of the lifting mechanism. The high-precision drawing roller, after passing the material between the first guide roller and the second guide roller, the first pulley can rotate under the action of the motor and the motor shaft, thereby driving the first connecting shaft, the second A guide roller rotates integrally with the first support, and at the same time, the belt rotates, thereby driving the second pulley and the first gear to rotate integrally. The second gear is meshed and connected with the first gear. The second gear, the second connecting shaft, the The second guide roller and the second support rotate as a whole. At this time, the second guide roller and the first guide roller rotate relative to each other, and the rotational speed is the same. The role of limit.

Description

technical field [0001] The invention relates to the related technical field of the textile industry, in particular to a high-precision drawing roller. Background technique [0002] The drawing roller is an important part of the textile industry. The length of the tooth pattern is generally more than 180mm, which is about five times longer than that of the general roller. The existing drawing roller is inconvenient to adjust the two guide rollers according to the thickness of the material. The distance between the two guide rollers can guide the material to move when they rotate relative to each other, but it is difficult to ensure that the rotation speed of the two guide rollers is the same, which will affect the guide effect. After using the device, it is inconvenient to disassemble the guide roller for cleaning. Repair or replace. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a high-precision drawing roller, so as to solve the inco...
