Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, and more specifically to a wear-resistant roller of a roller type shot blasting machine. Background Art

[0002] A shot blasting machine is a processing equipment that uses a shot blaster to throw steel sand and steel shots at high speed onto the surface of a material object. Especially when used in the construction of some large equipment, the surface of the steel plate material needs to be pre-treated. In the shot blasting machine, because the steel shots are easy to stick between the rollers when magnetized, as the shot blasting machine works, it is easy to produce an impression on the rollers during the extrusion process. Therefore, the rollers are conventional consumable parts and need to be replaced frequently.

[0003] The current means to solve the problem is to put a wear-resistant sleeve on the surface of the roller to protect the roller by isolation. For example, the patent application number 201220572377.0 discloses a wear-resistant roller for a shot blasting machine, in which the roller surface is provided with a protective sleeve. However, there are still some problems with the above patent, specifically,

[0004] 1) The wear-resistant sleeve and the roller are directly attached. During the rotation of the roller, if there is a gap between the wear-resistant sleeve and the roller due to size problems, the roller will wear due to friction between the wear-resistant sleeve and the roller;

[0005] 2) The wear-resistant sleeve and roller are installed with interference fit. This connection method will lead to poor connection effect based on the first problem, and it is easy to cause misalignment, causing the wear-resistant sleeve to slip on the roller;

[0006] 3) The wear-resistant sleeve is a long integral part. If it is severely worn, the entire sleeve needs to be replaced, which wastes costs. Utility Model Content

[0007] In order to overcome the technical problems raised in the above background, the utility model provides a wear-resistant roller of a roller type shot blasting machine.

[0008] In order to solve the above technical problems, the technical solutions of the present utility model are as follows:

[0009] A wear-resistant roller of a roller-type shot blasting machine includes a roller, both ends of the roller are provided with connecting shaft heads, a coaxial wear-resistant sleeve is provided on the roller, there is a gap between the outer wall of the roller and the inner wall of the wear-resistant sleeve, two connecting shaft heads are provided with positioning rings, the positioning rings are fixedly connected to both sides of the wear-resistant sleeve through fixing parts, and the two connecting shaft heads are also provided with retaining springs for axially fixing the positioning rings.

[0010] Preferably, the fixing part of the positioning ring is a first connecting block, which is arranged facing the wear-resistant sleeve, and multiple first connecting blocks are evenly arranged along the circumference of the positioning ring; connecting holes that cooperate with the first connecting blocks are reserved on both sides of the wear-resistant sleeve, and the first connecting block fixes the wear-resistant sleeve circumferentially by plugging and fixing it with the connecting holes.

[0011] Further preferably, the wear-resistant sleeve is provided on the roller in multiple sections, and the rollers between the multiple sections of the wear-resistant sleeve are provided with wear-resistant rings.

[0013] Further preferably, second connecting blocks are provided on both sides of the wear-resistant ring, the second connecting blocks are arranged facing the wear-resistant sleeves on both sides, and multiple second connecting blocks are evenly arranged along the circumference of both sides of the wear-resistant ring; a connecting hole that cooperates with the second connecting block is reserved on the side of the wear-resistant sleeve facing the wear-resistant ring, and the second connecting block fixes the wear-resistant sleeve circumferentially by plugging and fixing it with the connecting hole.

[0014] Further preferably, a rubber ring is provided between the wear-resistant sleeve and the roller.

[0015] Compared with the prior art, the beneficial effects of the technical solution of the utility model are:

[0016] The utility model provides a wear-resistant roller for a roller-type shot blasting machine, which protects the roller by non-contact installation of the roller and the wear-resistant sleeve. At the same time, the wear-resistant sleeve adopts multiple sections to reduce maintenance costs. Specifically,

[0017] 1) There is a gap between the roller and the wear-resistant sleeve. Connection holes are provided on both sides of the wear-resistant sleeve. Positioning rings are provided on both sides of the wear-resistant sleeve. A plurality of first connecting blocks are provided on the side of the positioning ring facing the wear-resistant sleeve.

This fixing method can ensure non-contact installation of the roller and the wear-resistant sleeve, and the roller can drive the wear-resistant sleeve to rotate.

[0018] 2) The wear-resistant sleeve is divided into multiple sections, and wear-resistant rings are arranged between the multiple sections. The wear-resistant rings are inserted into the connecting holes on the side of the wear-resistant sleeve through the second connecting block to fix the wear-resistant sleeve. At the same time, a rubber ring is installed between the wear-resistant ring and the roller to increase friction and improve the installation effect. This solution divides the wear-resistant sleeve into multiple sections. When it comes to a single wear-resistant sleeve, the maintenance cost of the wear-resistant sleeve can be reduced.

[0026] In order to better understand the purpose, structure and function of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific preferred embodiments.

[0027] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper", "lower", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as limiting the present invention. The specific dimensions used in the embodiments are only for illustrating the technical solution and do not limit the scope of protection of the present invention. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0028] Unless otherwise expressly specified or limited, terms such as "installed," "installed," "connected," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0029] Example 1:

[0030] See also Figure 1 、 2 3. The present application provides a wear-resistant roller of a roller-type shot blasting machine, comprising a roller 1. Connecting shaft heads 2 are provided at both ends of the roller 1. A coaxial wear-resistant sleeve 3 is sleeved on the roller 1. There is a gap between the outer wall of the roller 1 and the inner wall of the wear-resistant sleeve 3. Positioning rings 4 are sleeved on the two connecting shaft heads 2. The positioning rings 4 are fixedly connected to both sides of the wear-resistant sleeve 3 through fixing parts. The two connecting shaft heads 2 are also sleeved with retaining springs 6 for axially fixing the positioning rings 4.

[0031] In the above embodiment, both ends of the roller 1 are connected to the output component of the shot blasting machine through the connecting shaft head 2. The roller 1 and the wear-resistant sleeve 3 do not contact each other. The wear-resistant sleeve 3 is fixed by the side positioning ring 4 and the retaining spring 6, thereby avoiding wear and improving the service life of the roller 1.

[0032] More specifically, the fixing part of the positioning ring 4 is the first connecting block 41, which is arranged facing the wear-resistant sleeve 3, and multiple first connecting blocks 41 are evenly arranged along the circumference of the positioning ring 4; connecting holes 31 that cooperate with the first connecting blocks 41 are reserved on both sides of the wear-resistant sleeve 3, and the first connecting block 41 fixes the wear-resistant sleeve 3 circumferentially by plugging and fixing it with the connecting holes 31.

[0033] The first connecting block 41 on the side of the positioning ring 4 can be inserted into the connecting hole 31. Therefore, on the basis that the positioning ring 4 is fixed to the connecting shaft head 2 by the retaining spring 6, as the connecting shaft head 2 rotates, the positioning ring 4 drives the wear-resistant sleeve 3 to rotate through the first connecting block 41.

[0034] Example 2:

[0035] Based on the above examples, please refer to Figure 1 、 2 , 4, 5, the wear-resistant sleeve 3 is provided with multiple sections on the roller 1, and the roller 1 between the multiple sections of the wear-resistant sleeve 3 is provided with a wear-resistant ring 5. Dividing the wear-resistant sleeve 3 into multiple sections can reduce maintenance costs compared with a whole wear-resistant sleeve 3.

[0036] like Figure 1 and Figure 2As shown, the wear-resistant rings 5 ​​are in groups of two, which split the wear-resistant sleeve 3 into multiple sections of different lengths. When a single wear-resistant sleeve 3 is damaged, it is sufficient to replace the wear-resistant sleeve 3 at that position without replacing all of them.

[0037] More specifically, the material of the wear-resistant ring 5 is high manganese steel, which effectively improves the material strength.

[0038] More specifically, second connecting blocks 51 are provided on both sides of the wear-resistant ring 5, and the second connecting blocks 51 are arranged facing the wear-resistant sleeves 3 on both sides. There are multiple second connecting blocks 51 evenly arranged along the circumference of both sides of the wear-resistant ring 5; a connecting hole 31 that cooperates with the second connecting block 51 is reserved on the side of the wear-resistant sleeve 3 facing the wear-resistant ring 5, and the second connecting block 51 fixes the wear-resistant sleeve 3 circumferentially by plugging and fixing it with the connecting hole 31.

[0039] The second connecting block 51 on the side of the wear-resistant ring 5 can be inserted into the connecting hole 31. Since the wear-resistant ring 5 and the roller 1 are installed with interference fit, the roller 1 drives the wear-resistant ring 5 to rotate, and the wear-resistant ring 5 can fix the side of the wear-resistant sleeve 3.

[0040] More specifically, Figure 4 As shown, a rubber ring 52 is provided between the wear-resistant sleeve 3 and the roller 1 to increase friction and ensure power transmission between the roller 1 and the wear-resistant ring 5 .

[0041] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
