Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of shot blasting machine technology, and more specifically, to a noise-reducing shot blasting machine for roll production. Background Technology

[0002] Rolls are the main working parts and tools on rolling mills that cause continuous plastic deformation of metal. Rolls are mainly composed of three parts: roll body, roll neck and shaft head. In the production process of rolls, shot blasting machines are used to clean or strengthen the surface of the rolls. Shot blasting machines are casting equipment that uses high-speed shot thrown by shot blasters to clean or strengthen the surface of castings. Shot blasting machines can simultaneously remove sand, remove cores and clean castings. In existing technology, shot blasting machines used for roll production generate significant noise during operation because the high-speed shot thrown by the shot blaster impacts and contacts the workpiece. This leaves workers in a high-noise working environment, which has a significant impact on their health. Utility Model Content

[0022] like Figures 1-5As shown, this embodiment illustrates a noise-reducing shot blasting machine for roll production, comprising a shot blasting machine body 1, a mounting base 2, an L-shaped connecting plate 3, a spring-loaded connecting mechanism, an outer protective shell 4, a noise-reducing layer 5, a damping buffer layer 6, and a locking assembly. Compared to existing shot blasting machines for roll production that generate significant noise during operation, affecting the health of workers, this embodiment achieves noise reduction for the shot blasting machine body 1 through the cooperation of the outer protective shell 4, the noise-reducing layer 5, and the damping buffer layer 6. This reduces the volume of noise generated during the operation of the shot blasting machine body 1, providing a safer and more comfortable working environment. It provides staff with a good working environment. Through the cooperation between mounting base 2, L-shaped connecting plate 3 and spring-loaded connecting mechanism, the outer protective shell 4, noise reduction layer 5 and damping buffer layer 6 can be quickly installed or removed. This makes it convenient for staff to maintain or replace the noise reduction layer 5 and damping buffer layer 6, and ensures the noise reduction effect of the noise reduction layer 5 and damping buffer layer 6 on the shot blasting machine body 1. Through the locking component, the locking connection between the two L-shaped connecting plates 3 is realized, ensuring the stability of the outer protective shell 4, noise reduction layer 5 and damping buffer layer 6 after installation, and ensuring the use effect of the noise reduction structure. like Figure 1 As shown, multiple mounting seats 2 are installed on the main body 1 of the shot blasting machine. Two L-shaped connecting plates 3 are sleeved on the outer side of the mounting seats 2. Square blocks are installed on the upper and lower sides of the mounting seats 2. Square grooves are opened on the inner top and bottom walls of the L-shaped connecting plates 3. The width of the square grooves is adapted to the width of the square blocks. The square blocks limit the L-shaped connecting plates 3 through the square grooves, thereby ensuring the stability of the L-shaped connecting plates 3 when moving. Figure 2 , Figure 3 and Figure 4As shown, the spring-loaded connecting mechanism is located inside the L-shaped connecting plate 3. The spring-loaded connecting mechanism includes a limiting rod 101, a pressing plate 102, and a return spring 103. The limiting rod 101 is installed in the middle of the inner wall of the L-shaped connecting plate 3, and the other end of the limiting rod 101 is inserted into the mounting base 2. The pressing plate 102 is installed inside the limiting rod 101. The return spring 103 is sleeved on the limiting rod 101, and both ends of the return spring 103 are connected to the mounting base 2 and the pressing plate 102, respectively. A buffer pad is provided in the middle of the inner side of the pressing plate 102. The buffer pad buffers the pressing plate 102 and the mounting base 2, thus preventing direct collision between the pressing plate 102 and the mounting base 2. Two moving passages are provided on the mounting base 2. The pressing plate 102 and the return spring 103 are located inside the moving passages. When the pressing plate 102 moves with the limiting rod 101, it moves inside the moving passages. The outer protective shell 4 is installed... On the L-shaped connecting plate 3, multiple positioning blocks are installed on both sides of the shot blasting machine body 1. Multiple positioning grooves are opened on the inner side of the outer protective shell 4. The width of the positioning grooves is adapted to the width of the positioning blocks. The positioning blocks position the outer protective shell 4 through the positioning grooves, thereby realizing quick positioning when installing the outer protective shell 4. The noise reduction layer 5 is set inside the outer protective shell 4, and the damping buffer layer 6 is set inside the outer protective shell 4 and inside the noise reduction layer 5. The cooperation between the outer protective shell 4, the noise reduction layer 5 and the damping buffer layer 6 can reduce the noise of the shot blasting machine body 1, reduce the volume of noise generated during the operation of the shot blasting machine body 1, and provide the staff with a good working environment. The cooperation between the mounting base 2, the L-shaped connecting plate 3 and the spring-loaded connecting mechanism can realize the quick installation or removal of the outer protective shell 4, the noise reduction layer 5 and the damping buffer layer 6, which facilitates the staff to maintain or replace the noise reduction layer 5 and the damping buffer layer 6. like Figure 1 As shown, the locking assembly is installed on one of the two sides of the L-shaped connecting plate 3. The locking assembly includes a connecting ear 201, a connecting tube 202, a connecting post 203, and a grip 204. The connecting ear 201 is installed on the L-shaped connecting plate 3. The connecting tube 202 is inserted into the connecting ear 201 on one side of the two sides, and the connecting post 203 is inserted into the connecting ear 201 on the other side of the two sides. Both the connecting tube 202 and the connecting post 203 are equipped with grips 204. The inner wall of the connecting tube 202 is provided with internal threads, and the outer side of the connecting post 203 is provided with external threads. The connecting tube 202 is threadedly locked to the connecting post 203 through the internal and external threads. The locking assembly can realize the locking connection between the two L-shaped connecting plates 3, ensuring the stability of the outer protective shell 4, the noise reduction layer 5, and the damping buffer layer 6 after installation, and ensuring the effectiveness of the noise reduction structure.

[0023] Working principle: The outer protective shell 4 covers the outside of the shot blasting machine body 1. The noise reduction layer 5 and the damping buffer layer 6, located inside the outer protective shell 4, absorb and reduce the noise generated during the operation of the shot blasting machine body 1, thus achieving noise reduction. When maintenance or replacement of the noise reduction layer 5 or the damping buffer layer 6 is required, the operator turns the handle 204 counterclockwise. The handle 204 drives the connecting pipe 202 and the connecting column 203 to rotate, unscrewing the connecting column 203 from the inside of the connecting pipe 202. This cancels the locking mechanism's locking connection between the two L-shaped connecting plates 3. After cancellation, the operator pushes the L-shaped connecting plate 3... Plate 3 moves outward along mounting base 2. L-shaped connecting plate 3 drives extrusion plate 102 to move via limit rod 101. Extrusion plate 102 compresses return spring 103. L-shaped connecting plate 3 drives outer protective shell 4 to move outward. After moving to the corresponding position, the staff maintains or replaces the noise reduction layer 5 and damping buffer layer 6 set inside the outer protective shell 4. After the operation is completed, L-shaped connecting plate 3 is released. Under the action of spring-loaded connecting mechanism, L-shaped connecting plate 3 drives outer protective shell 4, noise reduction layer 5 and damping buffer layer 6 back to their original positions. Then, the two L-shaped connecting plates 3 are locked together by locking assembly.
