Description

Technical Field

[0001] The utility model relates to the technical field of conveying belt roller equipment, in particular to a polyurethane coating layer of a tile shell type roller. Background Art

[0002] The rollers used for the initial operation of the transport belts in coal mines and cement plants are in several forms, including main rollers without rubber, main rollers with rubber, main rollers with polyurethane rubber, and main rollers with polyurethane casting. They are installed on the transport belt bracket for driving operation. The outer rubber or polyurethane rubber sheet is a prismatic pattern, which can prevent the belt from slipping. The rubber sheet pattern is easily damaged and worn after long-term operation, which can cause the belt to slip and need to be re-coated. There are two problems with the advantages: one is that in the process of re-coating, the roller must be removed and raised to the ground. Second, it must be transported to the maintenance factory to remove the waste rubber before it can be re-coated. After the repair, the roller is transported to the original position of the well and the production can be resumed after the installation is complete. In the process of replacing the waste rubber, the disassembly and installation procedures are too much for the workers, which also affects the long-term production, resulting in reduced production and increased production costs. Utility Model Content

[0003] The utility model provides a polyurethane coating layer of a tile shell type roller.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A polyurethane coating layer of a tile shell type roller comprises a prismatic polyurethane wrapping layer, a main transport roller body, fish screws, a metal tile shell arc plate, a tile shell arc plate fixing strip, fixing holes, and interval seams. A plurality of metal tile shell arc plates are arranged on the cylindrical side surface of the main transport roller body, and a prismatic polyurethane wrapping layer is arranged on the outer side of the plurality of metal tile shell arc plates. The inner side of the prismatic polyurethane wrapping layer is fixedly connected to the outer side of the metal tile shell arc plate. The plurality of metal tile shell arc plates are symmetrically provided with tile shell arc plate fixing strips at the left and right ends, and a plurality of fixing holes are opened on the tile shell arc plate fixing strips. Fish screws are arranged in the plurality of fixing holes, and the left and right ends of the plurality of metal tile shell arc plates are fixedly connected to the main transport roller body through the fixing holes on the tile shell arc plate fixing strips and a plurality of fish screws.

[0006] Furthermore, the plurality of metal tile shell arc plates are evenly distributed on the cylindrical side of the main transport drum body in a ring array with the central axis of the main transport drum body as the axis.

[0007] Furthermore, the plurality of fixing holes are evenly distributed on the tile shell arc plate fixing strip in a ring array with the central axis of the main transport drum body as the axis.

[0008] Furthermore, interval gaps are left between the plurality of metal tile shell arc plates, and the interval gaps are sealed with sealing glue.

[0009] Beneficial effects: The utility model integrates the prismatic polyurethane wrapping layer and the metal tile shell arc plate into one piece, puts them on the roller to be replaced, fixes them with clips, and fixes the two ends with tile shell arc plate fixing strips and fish screws. When each metal tile shell arc plate is installed, a spacing gap is left between them for easy adjustment. After all the tile shells are installed, the spacing gap is sealed with special sealing glue to prevent debris from penetrating into the tile shell space. When replacing the prismatic polyurethane wrapping layer, the roller does not need to be disassembled, and the construction can be carried out on site, which is convenient and quick to install, reducing the workload of workers. After installation, production can be started, greatly improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0016] Reference Figure 1-3A polyurethane coating layer of a tile shell type roller comprises a prismatic polyurethane wrapping layer 1, a main transport roller body 2, fish screws 3, a metal tile shell arc plate 4, a tile shell arc plate fixing strip 5, fixing holes 6, and interval seams 7. The cylindrical side of the main transport roller body 2 is provided with a plurality of metal tile shell arc plates 4, and the outer sides of the plurality of metal tile shell arc plates 4 are all provided with a prismatic polyurethane wrapping layer 1. The inner side of the prismatic polyurethane wrapping layer 1 is fixedly connected to the outer side of the metal tile shell arc plate 4.
