Description

Technical Field

[0001] This utility model relates to the field of shot blasting equipment technology, specifically a shot blasting machine gap sealing component. Background Technology

[0002] A shot blasting machine is a surface treatment device primarily used for cleaning, strengthening, and surface treatment of metal parts. It propels steel shot or other abrasive materials onto the workpiece surface via a high-speed rotating impeller to remove impurities such as rust, scale, and old paint layers, thereby improving the surface quality and increasing the material's fatigue strength. In traditional shot blasting machines, after welding, a cavity is formed between the protective plate and the chamber. This cavity buffers the impact of the shot on the protective plate during ejection and protects the chamber. Damage to this cavity can cause changes in the shot's velocity and angle, resulting in direct impact on the shot blasting chamber, leading to structural damage and equipment malfunction. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a gap sealing component for shot blasting machines.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a shot blasting machine gap sealing assembly, comprising two L-shaped protective plates disposed at the cavity between the protective plate at the shot blasting machine inlet and the chamber body. A first protrusion is provided at the left end of the protective plate; a second protrusion is provided to the right of the first protrusion, with its height located at the middle position of the first protrusion; a first groove is provided on the upper left side of the protective plate, located to the right of the second protrusion; a third protrusion is provided at the right end of the protective plate, with its length and width being the same as the length and width of the second protrusion; a second groove is provided on the upper right side of the protective plate, located to the left of the third protrusion; a first fixing hole is provided below the first and second grooves; the first and second grooves are of the same size.

[0005] Preferably, the two protective plates are combined to form a rectangle, the length and width of which are the same as the length and width of the inner wall of the chamber at the feed inlet of the shot blasting machine.

[0006] Preferably, the first groove and the second groove match the protruding parts of the upper and lower short plates of the guard plate.

[0007] Preferably, two second fixing holes are provided on each of the two long sides of the bottom of the chamber, which match the positions of the first fixing holes.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] On the one hand, it fits closely with the shot blasting guard plate and chamber, sealing and protecting the cavity formed between the shot blasting guard plate and chamber, preventing the shot from being thrown into the cavity between the guard plate and chamber at high speed during shot blasting, directly impacting the chamber and causing structural damage.

[0010] On the other hand, the design is detachable, so if it is damaged later, it can be replaced individually, reducing the user's operating costs. Attached Figure Description

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0016] Please refer to the reference. Figure 1 , Figure 2 as well as Figure 3This utility model provides a gap sealing assembly for a shot blasting machine, including two L-shaped protective plates 100, disposed in the cavity 400 between the protective plate 200 at the feed inlet of the shot blasting machine and the chamber 300. A first protrusion 120 is provided on the left end of each protective plate 100; a second protrusion 130 is provided on the right side of the first protrusion 120, with its height located at the middle position of the first protrusion 120; a first groove 150 is provided on the upper left side of each protective plate 100, located to the right of the second protrusion 130; a third protrusion 140 is provided on the right end of each protective plate 100, with its length and width being the same as the length and width of the second protrusion 130; a second groove 160 is provided on the upper right side of each protective plate 100, located to the third protrusion 140. On the left side; a first fixing hole 110 is provided below the first groove 150 and the second groove 160; the first groove 150 and the second groove 160 are the same size, which facilitates the splicing and installation of the two protective plates 100 and facilitates disassembly and replacement; at the same time, the protective plate 100 and the chamber 300 are precisely fixedly connected through the two fixing holes. After the protective plate 100 is spliced, its internal shape fits tightly with the outer periphery of the protective plate 200. A protective barrier is formed at the cavity 400 between the protective plate 200 and the chamber 300 at the feed port of the shot blaster. This prevents the shot from being ejected from the discharge port when it enters the shot blaster and is propelled by the high-speed impeller inside, and then ejected into the cavity 400, directly impacting the chamber 300 and causing structural damage.

[0017] Preferably, the two protective plates 100 are combined to form a rectangle, the length and width of which are the same as the length and width of the inner wall of the chamber 300 of the shot blasting inlet, so that the protective plates 100 fit together and prevent gaps from being generated.

[0018] Preferably, the first groove 150 and the second groove 160 match the protruding parts of the upper and lower short plates of the guard plate 200, so that the two guard plates 100 fit tightly with the guard plate 200 after splicing and installation, preventing gaps from being generated.

[0019] Preferably, two second fixing holes 301 are provided on the two long sides of the bottom of the chamber 300, which match the positions of the first fixing holes 110, so that the protective plate 100 and the chamber 300 are accurately fixed, thereby improving the stability between the two.

[0020] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
