Description

Technical Field

[0001] This application relates to the technical field of shot blasting machines, and particularly to a shot blasting machine with reduced noise. Background Art

[0002] A shot blasting machine is a device that shoots steel shots at high speed onto the surface of workpieces to achieve purposes such as cleaning, strengthening, and surface finishing. The working principle of most shot blasting machines is to use an electric motor to drive the impeller body to rotate, and rely on the centrifugal force to throw the shot onto the surface of the workpiece, thereby realizing the treatment of the workpiece surface.

[0003] Upon investigation, the publication number: CN213970676U discloses a vertical shot blasting machine, which discloses "including: a vertical moving frame, a controller, a main machine, a dust collector, a shot receiving mechanism, and a fixing mechanism. The controller, the main machine, the dust collector, the shot receiving mechanism, and the fixing mechanism are all arranged on the vertical moving frame; the main machine includes a sand box and a shot blasting structure. The sand box is located above the shot blasting structure, the opening of the sand box faces upward, the bottom of the sand box is communicated with the shot blasting structure, and at the same time, the side of the shot blasting structure is communicated with the side of the sand box and other technical solutions. By changing the structure of the traditional shot blasting machine, the main machine and the sand box are vertically arranged. At the same time, according to the working frequency of the shot blasting machine, the rebound angle of the shot blasting, etc., the included angle between the shot injection pipe and the projection pipe and the included angle between the projection pipe and the shot blasting machine are determined, ensuring that while vertical shot blasting can be carried out, all the shot blasting can bounce back into the sand box through the return shot pipe, greatly improving the shot blasting quality and speed and other technical effects".

[0004] Regarding the above related technologies, the inventor believes that the existing shot blasting machines have poor noise reduction ability. Since the noise generated by the shot blasting machines during processing is relatively noisy, it will cause damage to the human body and the environment. If the noise generated by them cannot be reduced, it will cause irreversible harm to human health and the environment in the long run. And the processing efficiency of most shot blasting machines is limited, and it is not convenient to place the workpieces. Therefore, a shot blasting machine with reduced noise is needed to solve the above problems. Summary of the Utility Model

[0031] The following will further elaborate on this application in conjunction with the attached Figure 1 - attached Figure 4 drawings for a more detailed description.

[0032] Embodiment 1

[0033] A shot blasting machine for reducing noise, referring to Figures 1 - 3 , includes a machine body 1. Both ends of the machine body 1 are adhered with side sound insulation boards 2, and both the upper and lower ends of the machine body 1 are adhered with connecting sound insulation boards 21. One end of the machine body 1 is adhered with a rear sound insulation board 22. The internal structures of the side sound insulation board 2, the connecting sound insulation board 21, and the rear sound insulation board 22 are the same, and they are all composed of multiple layers of materials. The side sound insulation board 2 includes an outer shell 3. One inner wall of the outer shell 3 is adhered with a sound insulation cotton layer 31. One end of the sound insulation cotton layer 31 is adhered with a first sound insulation layer 32. The specific material of the first sound insulation layer 32 is polyester fiber sound absorption board. The specific material of the second sound insulation layer 33 is ceramic aluminum sound absorption board. One end of the first sound insulation layer 32 is adhered with the second sound insulation layer 33. One end of the second sound insulation layer 33 is adhered with a third sound insulation layer 34. One end of the third sound insulation layer 34 is adhesively connected to one inner wall of the outer shell 3. The machine body 1 is the shot blasting machine body. The machine body 1 is wrapped by the side sound insulation board 2, the connecting sound insulation board 21, and the rear sound insulation board 22 for sound insulation and noise reduction. Each sound insulation board protects the internal structures through the outer shell 3. The sound insulation cotton layer 31, as the first layer structure, partially isolates the noise. The first sound insulation layer 32 and the second sound insulation layer 33 composed of polyester fiber sound absorption board and ceramic aluminum sound absorption board are both good noise reduction materials, further weakening the noise generated by the machine body 1. Combined with the composite use of the third sound insulation layer 34, the combined use of multiple sound insulation materials further improves the sound insulation and noise reduction effect, effectively reducing the noise generated by the shot blasting machine and reducing the pollution to the human body and the environment.

[0034] Referring to Figure 2 , one end of the machine body 1 is bolted and connected with a door frame 4. Side doors 41 are rotatably arranged on both inner walls of the door frame 4. A sound insulation door panel 23 is adhered to the outer surface of the side door 41. A handle 42 is adhered to one side of one end of the sound insulation door panel 23. The door frame 4 and the machine body 1 are bolted and connected. And the internal structure of the sound insulation door panel 23 is the same as that of the side sound insulation board 2. After the workpiece is placed, the side door 41 is closed. At this time, the overall sound insulation and noise reduction effect is further improved through the sound insulation door panel 23, and the handle 42 facilitates the opening and closing of the side door 41.

[0035] Referring to Figure 3 , the third sound insulation layer 34 is specifically a honeycomb structure, and the inside of the third sound insulation layer 34 is in a hollow state. The honeycomb hollow third sound insulation layer 34 has a relatively high structural strength and a strong sound insulation effect.

[0036] The implementation principle of the embodiment of the present application is as follows: The body 1 is the main body of the shot blasting machine. The side sound insulation board 2, the connecting sound insulation board 21 and the rear sound insulation board 22 wrap the body 1 to carry out sound insulation and noise reduction. Each sound insulation board is protected by the outer shell 3 to protect the internal structures of each layer. The sound insulation cotton layer 31, as the first layer structure, partially isolates the noise. The first sound insulation layer 32 and the second sound insulation layer 33 composed of polyester fiber sound absorption boards and ceramic aluminum sound absorption boards are both good noise reduction materials, which further weaken the noise generated by the body 1. Combined with the composite use of the third sound insulation layer 34, the combined use of a variety of sound insulation materials further improves the sound insulation and noise reduction effect, effectively reducing the noise generated by the shot blasting machine and reducing the pollution to the human body and the environment.

[0037] After the workpiece is placed, the side door 41 is closed. At this time, the overall sound insulation and noise reduction effect is further improved through the sound insulation door panel 23. The handle 42 facilitates the opening and closing of the side door 41.

[0038] The honeycomb hollow third sound insulation layer 34 has a relatively high structural strength and a strong sound insulation effect.

Eighteen columns 64 are welded to the upper end of the support ring 63, and eighteen hooks 65 are welded to the lower end of the support ring 63. The three support rings 63 are distributed at equal intervals up and down. The eighteen columns 64 and hooks 65 on one of the support rings 63 are both annularly distributed, making the distribution of the support and placement structure relatively uniform, reducing the possibility of collision between each workpiece. The workpiece to be shot blasted is placed on the support plate 6, specifically placed at the upper and lower ends of the support ring 63 connected by the support column 61 and the connecting column 62. The hooks 65 and the columns 64 can both hoist the workpiece, and more workpieces can be placed at one time, improving the efficiency of shot blasting processing.
