High-precision drawing roller

Abstract

The invention discloses a high-precision drawing roller. The drawing roller 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 rotationally connected to a supporting plate on the left side, and the second connecting shaft is rotationally connected to the left side of the bottom of the lifting mechanism. According to the high-precision drawing roller, after a material passes through the space between a first material guide roller and a second material guide roller, a first belt wheel can rotate under the action of the motor and a motor shaft, so that the first connecting shaft, the first material guide roller and a first bracket are driven to rotate integrally, and meanwhile, the belt runs, so that a second belt wheel and a first gear are driven to rotate integrally. A second gear and the first gear are connected together in a meshed mode, the second gear, the second connecting shaft, the second material guide roller and a second bracket rotate integrally, at the moment, the second material guide roller and the first material guide roller rotate oppositely, the rotating speed is the same, the rotating speed difference does not exist, the material can be better guided to move backwards conveniently, and the limiting effect on the material is achieved.

Description

technical field [0001] The invention relates to the technical field related to 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 the general roller. The existing drawing roller is inconvenient to adjust the distance between the two guide rollers according to the thickness of the material before use. The distance between the two material guide rollers can guide the material to move when they rotate relative to each other, but it is difficult to ensure that the speed of the two material guide rollers is the same, which will affect the material guide effect, and it is inconvenient to disassemble the material guide roller for cleaning after using the device Repair or replace.

Problems solved by technology

[0003] The object of the present invention is to provide a kind of high-precision draw frame roller, to solve the existing draw frame roller proposed in the above-mentioned background technology before use, it is inconvenient to adjust the distance between the two material guide rollers according to the thickness of the material, two The 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 material guide effect. After using the device, it is inconvenient to disassemble the guide rollers for cleaning, maintenance or replacement.
