Abstract
Description
Technical Field
[0001] This utility model relates to the field of rollers, and more specifically, to a transfer roller. Background Technology
[0002] A transfer roller is a type of roller used to transport layered materials such as fabrics, paper, and films. By rotating, the layered material that is in contact with the surface of the transfer roller is transported to the area where the corresponding processing stage is located.
[0003] Generally speaking, the layered materials that the transfer rollers deal with during operation are relatively soft, and these materials have certain requirements for surface texture and integrity. Therefore, when defects appear on the surface of the transfer rollers, scratches will appear on the layered materials, and the rollers need to be replaced. However, the cost of replacing the entire roller is too high. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a transmission roller.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a transmission roller, including a roller cylinder, wherein a plurality of replacement pieces are detachably connected to the outer side wall of the roller cylinder, the replacement pieces are arranged in a circumferential array around the axis of the roller cylinder, and the gap width between adjacent replacement pieces is smaller than the width of the replacement pieces.
[0006] The present invention is further configured such that both ends of the replacement piece are fixed to the roller by bolts.
[0007] The present invention is further configured such that the surface of the roller is provided with several planes that fit against the outer wall of the replacement piece.
[0008] The present invention is further configured such that: a protrusion is fixedly connected to the side of the replacement piece near the roller, and the protrusion is embedded in the roller.
[0009] The present invention is further configured such that the length of the replacement piece is greater than the length of the roller.
[0010] The present invention is further configured such that the thickness of the replacement piece gradually decreases along the direction close to the adjacent replacement piece.
[0011] In summary, this utility model has the following beneficial effects: through the independent detachable connection structure between each individual replacement piece and the roller, when any replacement piece has a defect on its surface, the replacement piece can be removed and a new replacement piece can be installed in the corresponding position, which saves the cost of maintaining the transmission roller. The bolts and the stepped holes that cooperate with the bolts are set at both ends of the replacement piece to prevent the material from contacting the stepped holes and bolts.

[0014] Figure 3 This is a schematic diagram of the replacement piece in this utility model.
[0015] In the diagram: 1. Roller; 2. Replacement piece; 3. Bolt; 4. Protrusion. Detailed Implementation
[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0017] Example: A transfer roller, such as Figure 1 , Figure 2 As shown, the roller 1 is included, and a number of replacement pieces 2 are detachably connected to the outer wall of the roller 1. The replacement pieces 2 are arranged in a circumferential array around the axis of the roller 1. The gap width between adjacent replacement pieces 2 is smaller than the width of the replacement piece 2. Specifically, in this embodiment, twenty-four replacement pieces 2 are detachably connected to the surface of the roller 1. Each single replacement piece 2 is independently and detachably connected to the roller 1. That is, when any replacement piece 2 has a defect on its surface, the replacement piece 2 can be removed and replaced with a new replacement piece 2 at the corresponding position, thus saving the cost of maintaining the transmission roller.
[0018] like Figure 1 , Figure 2 , Figure 3 As shown, the two ends of the replacement piece 2 are fixed to the roller 1 by bolts 3. The surface of the roller 1 is provided with several planes that fit against the outer wall of the replacement piece 2. A protrusion 4 is fixedly connected to the side of the replacement piece 2 near the roller 1. The protrusion 4 is embedded in the roller 1. Specifically, both ends of the replacement piece 2 are provided with stepped holes. The bolts 3 pass through the replacement piece 2 and are threadedly connected to the roller 1. The bolts 3 and the stepped holes that mate with the bolts 3 are set at both ends of the replacement piece 2 to prevent the material from contacting the stepped holes and the bolts 3. The protrusion 4 is integrally formed with the replacement piece 2. The protrusion 4 is located on the side of the replacement piece 2 away from the material. The connection strength between the replacement piece 2 and the roller 1 is improved by the protrusion 4 embedded in the roller 1.
[0019] like Figure 1 , Figure 2As shown, the length of the replacement piece 2 is greater than the length of the roller 1. The thickness of the replacement piece 2 gradually decreases along the direction close to the adjacent replacement piece 2. Specifically, both ends of the replacement piece 2 extend beyond the edge of the roller 1. This makes it easier to pry up the replacement piece 2 that needs to be replaced when disassembling the replacement piece 2. The cross-section of the replacement piece 2 consists of a rectangle and an isosceles trapezoid. The side of the isosceles trapezoid away from the roller 1 is the smaller end. Through the change in the thickness of the replacement piece 2, a trapezoidal gap is formed between adjacent replacement pieces 2. This allows the operator to restrict the rotation of the transmission roller by contacting the surface of the transmission roller, making it easier for the operator to perform the operation.
[0020] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
