Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a low-noise overhead conveyor shot blasting machine. Background Technology

[0002] The working principle of a overhead conveyor shot blasting machine is to suspend the workpiece in the air using a rotating overhead conveyor (or hook), and then strike the workpiece surface with shot through high-speed rotating blades or blades on the hook.

[0003] Shot blasting machines utilize steel shot fed onto a high-speed rotating disc. Centrifugal force propels the shot at high speed, impacting the surface of parts to achieve a polished finish. Shot blasting creates compressive stress on the surface of parts and produces no silicon powder, resulting in minimal environmental pollution. However, during operation, the shot balls fall and impact the machine's recovery section. Existing shot blasting machines lack noise reduction mechanisms for this recovery section. Before entering the circulation pipe, the shot balls impact the inner wall of the recovery section, generating significant noise and affecting the surrounding environment.

[0004] Based on this, a low-noise overhead conveyor shot blasting machine is proposed. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a low-noise overhead conveyor shot blasting machine. By employing a buffer installation method combined with sound insulation measures, it can reduce vibration during operation and decrease the noise generated when the shot blasting balls impact the ground.

[0006] The technical solution to achieve the purpose of this utility model is as follows: a low-noise overhead conveyor shot blasting machine, comprising a base plate, a rubber plate fixedly connected to the upper surface of the base plate, multiple support legs provided on the upper surface of the rubber plate, a soundproof cover fixedly connected to the top of the multiple support legs, an organic body provided on the inner wall of the soundproof cover, a recovery hopper provided on the inner wall of the organic body, a soundproof hopper fixedly connected to the inner wall of the recovery hopper, two sliding grooves opened on both sides of the inner wall of the soundproof hopper, sliders slidably connected to the inner walls of the two sliding grooves, a common deceleration plate fixedly connected to one side of the two sliders, a rubber pad fixedly connected to the upper surface of the deceleration plate, a support plate fixedly connected to the inner wall of the soundproof hopper, multiple springs fixedly connected to the upper surface of the support plate, the tops of the multiple springs respectively fixedly connected to the lower surface of the deceleration plate, a rotating drum rotatably connected to the inner wall of the recovery hopper, and multiple guide vanes fixedly connected to the surface of the rotating drum.

[0007] In some embodiments, sound-insulating cotton is provided between the body and the recycling hopper, and a circulation pipe is fixedly connected to the lower surface of the recycling hopper.

[0008] In some embodiments, a plurality of screws are fixedly connected to the upper surface of the base plate, and each of the screws is fitted with a compression spring.

[0009] In some embodiments, the upper surfaces of the plurality of support legs are perforated with sliding holes, the inner walls of the plurality of sliding holes are slidably connected to the surfaces of the corresponding plurality of screws, the top end of the compression spring is fixedly connected to the lower surface of the support leg, and the surface of the screw is threaded with a nut.

[0010] In some embodiments, two sound-absorbing panels are fixedly connected to the surface of the body.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] Firstly, the rubber pads on the deceleration plates of this invention can buffer the shot blasting balls. Contact with the rubber pads reduces the noise generated when the shot blasting balls impact the deceleration plates. The grooves, sliders, and springs further buffer the shot blasting balls upon impact, preventing rigid contact and improving noise reduction. The two sets of staggered deceleration plates reduce the falling speed of the shot blasting balls. Combined with the rotating drum and guide vanes inside the recovery hopper, the shot blasting balls passing through the deceleration plates are guided through the guide vanes to the connection between the circulation pipe and the recovery hopper, reducing the likelihood of contact between the shot blasting balls and the inner wall of the recovery hopper, thus reducing the possibility of noise generated by the shot blasting balls impacting the inner wall of the recovery hopper.

[0013] Secondly, this utility model allows the support legs on the rubber plate to be mounted on the screw, which can work with the nut and compression spring to achieve flexible installation of the machine body during shot blasting, thus avoiding excessive noise during operation.

[0014] This solves the problem that existing shot blasting balls would hit the inner wall of the recovery unit before entering the circulation pipe, generating significant noise and affecting the surrounding environment. Attached Figure Description

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved, low-noise overhead conveyor shot blasting machine. The technical solution of this utility model is as follows:

[0024] like Figures 1-4As shown, a low-noise overhead conveyor shot blasting machine includes a base plate 1. A rubber plate 2 is fixedly connected to the upper surface of the base plate 1. Multiple support legs 3 are arranged on the upper surface of the rubber plate 2. The support legs 3 are T-shaped. The tops of the multiple support legs 3 are fixedly connected to the same soundproof cover 5. The soundproof cover 5 is made of existing soundproofing material and is adapted to the surface of the machine body 4. The inner wall of the soundproof cover 5 is provided with the machine body 4. The inner wall of the machine body 4 is provided with a recovery hopper 8. A soundproof hopper 10 is fixedly connected to the inner wall of the recovery hopper 8. The soundproof hopper 10 is adapted to fit against the inner wall of the recovery hopper 8 and also uses existing soundproofing material. Two sliding grooves 17 are opened on both sides of the inner wall of the soundproof hopper 10. Sliding sliders 18 are slidably connected to the inner walls of the two sliding grooves 17. A deceleration plate 13 is fixedly connected to one side of the slider 18. The deceleration plate 13 can reduce the falling speed of the shot blasting ball and reduce the impact force. A rubber pad 15 is fixedly connected to the upper surface of the deceleration plate 13. The rubber pad 15 can absorb the noise generated when the shot blasting ball hits the deceleration plate 13 during its fall. A support plate 14 is fixedly connected to the inner wall of the soundproof hopper 10. Multiple springs 16 are fixedly connected to the upper surface of the support plate 14. The tops of the multiple springs 16 are fixedly connected to the lower surface of the deceleration plate 13. A rotating cylinder 11 is rotatably connected to the inner wall of the recovery hopper 8. Multiple guide vanes 12 are fixedly connected to the surface of the rotating cylinder 11. The guide vanes 12 are angled, which can allow the shot blasting ball to accumulate on the vanes and rotate under gravity for guidance.

[0025] like Figure 2 and Figure 4 As shown, in one embodiment, a sound-insulating cotton 9 is provided between the body 4 and the recycling hopper 8. The sound-insulating cotton 9 can fill the gap between the recycling hopper 8 and the inner wall of the body 4, further reducing the propagation of noise. A circulation pipe 7 is fixedly connected to the lower surface of the recycling hopper 8.

[0026] Multiple screws 19 are fixedly connected to the upper surface of the base plate 1. Each screw 19 is fitted with a compression spring 20. The support leg 3 can be fixed by the screws 19, and the compression spring 20 can provide flexible support.

[0027] like Figure 1 and Figure 4 As shown, in one embodiment, the upper surfaces of multiple support legs 3 are perforated with sliding holes, the inner walls of the multiple sliding holes are slidably connected to the surfaces of corresponding multiple screws 19, the top end of the compression spring 20 is fixedly connected to the lower surface of the support leg 3, and the surface of the screw 19 is threadedly connected with a nut 21. The cooperation between the nut 21 and the screw 19 can limit the top of the support leg 3.

[0028] Two sound-absorbing panels 6 are fixedly connected to the surface of the body 4.

[0029] The specific working method is as follows: During use, after the shot blasting ball cleans the metal tools hanging on the suspension rack, before entering the circulation pipe 7, the shot blasting ball first contacts the deceleration plate 13. The rubber pad 15 set on the deceleration plate 13 can buffer the shot blasting ball, and the contact with the rubber pad 15 can reduce the noise generated when the shot blasting ball hits the deceleration plate 13. The set sliding groove 17, slider 18 and spring 16 can buffer the deceleration plate 13 when the shot blasting ball hits the deceleration plate 13, which can avoid rigid contact when the shot blasting ball hits the deceleration plate 13, and further improve the noise reduction effect. The two sets of staggered deceleration plates 13 can reduce the noise generated when the shot blasting ball hits the deceleration plate 13. The falling speed of the shot, combined with the rotating drum 11 and guide vanes 12 inside the recovery hopper 8, allows the shot passing through the deceleration plate 13 to be guided through the guide vanes 12 into the connection between the circulation pipe 7 and the recovery hopper 8, reducing the possibility of the shot contacting the inner wall of the recovery hopper 8. This reduces the possibility of noise generated by the shot impacting the inner wall of the recovery hopper 8. The support legs 3 on the rubber plate 2 are mounted on the screw 19 and can work with the nut 21 and compression spring 20 to achieve flexible installation of the machine body 4 during shot blasting, avoiding excessive noise during operation. The soundproof bucket 10 on the inner wall of the recovery hopper 8 and the soundproof cover 5 on the outside of the machine body 4 can both achieve noise reduction.

Matters not covered in this utility model are common knowledge to those skilled in the art.
