Description

Technical Field

[0001] The utility model relates to the technical field of cloth guide rollers, in particular to a cloth guide step roller. Background Art

[0002] The cloth guide roller is a dyeing and finishing equipment used to support and guide the fabric to run in a certain direction. The cloth guide roller can adjust the tension of the fabric in the running state. Patent announcement number CN202359372U discloses a cloth guide roller, including a roller body, shaft heads are respectively provided at both ends of the roller body, and a polyetheretherketone coating is provided on the outer surface of the roller body. There are many cloth guide rollers similar to the above patents and disclosed. These cloth guide rollers generally have the following characteristics: containing a roller body, the roller body is cylindrical, and shaft heads are provided on both sides of the roller body. Moreover, the roller bodies of these rollers are sealed and can only rely on the contact surface between the roller body surface and the air for heat dissipation, and the heat dissipation area is very limited.

[0003] Publication No. CN205133985U discloses a cloth guide roller, comprising a roller body and a shaft head. This solves the problem of fabric frills easily forming when cold-washing fabric directly after high-temperature processing. The key technical solution is that the roller body is circumferentially and equidistantly fixed with multiple identical support plates arranged radially along the roller body. Each support plate is equipped with a heat sink on the top of the side opposite the roller body, which contacts and conducts the fabric and provides tension. A gap exists between adjacent heat sinks, effectively reducing the temperature of the fabric surface.

[0004] Although the existing technology has increased the heat dissipation area to a certain extent, the fabric and the cloth guide roller are prone to slippage and displacement. Therefore, we propose a cloth guide step roller. Utility Model Content

[0005] The purpose of the utility model is to provide a cloth guiding step roller to solve the problems in the prior art.

[0006] To achieve the above object, the utility model provides the following technical solution: a cloth guide step roller, comprising a central shaft, end plates rotatably mounted at both ends of the central shaft, a plurality of middle plates being mounted at equal intervals between the two end plates, and the middle plates and the end plates being connected by connecting rods;

[0007] A plurality of arc-shaped plates are provided on the outer side of the middle plate, the plurality of arc-shaped plates are arranged in a ring shape, and a plurality of grooves are provided on the outer side of the arc-shaped plates at equal intervals;

[0012] Preferably, the end plates and the central shaft are connected via bearings, and the middle plates and the central shaft are connected via bearings.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Multiple curved plates are set on the outside of the middle plate. The multiple curved plates are arranged in a ring shape. Due to the gaps between the curved plates, the contact area between the fabric and the air can be increased, thereby not affecting the heat dissipation of the fabric; multiple grooves are set at equal intervals on the outside of the curved plates. The grooves can improve the anti-slip performance between the fabric and the curved plates, thereby reducing the possibility of fabric deviation. BRIEF DESCRIPTION OF THE DRAWINGS
