Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a low-noise sealed shot blasting machine. Background Technology

[0002] Shot blasting machines are an important surface treatment equipment, widely used in the cleaning and strengthening of workpieces in industries such as casting, forging, and automobile manufacturing. Shot blasting machines generate noise during operation.

[0003] A shot blasting machine with a soundproof protective door, disclosed in CN220806948U, facilitates the replacement of the crushing structure and ensures stable operation of the food crushing device. The shot blasting machine includes a machine body with a processing chamber inside. A track is installed at the outer end of the processing chamber, located around the top, bottom, and right sides of the chamber. A baffle is installed on the left side of the processing chamber. The track has a U-shaped structure, with both ends extending outside the machine body. This invention utilizes a sliding door panel installed at the front of the processing chamber. By moving the door panel horizontally within the track to the front of the processing chamber, an air pump inflates or deflates an air bladder strip. The inflated air bladder strip is inserted into a sealing groove, thus sealing the door panel and achieving low-noise operation of the shot blasting machine.

[0004] The device uses a double-door design to seal the machine body. However, when the door slides, there will be a certain gap between it and the outer wall of the machine body. This gap not only allows the noise generated during processing to leak out, but also allows the dust generated during processing to drift out through the gap, thus polluting the surrounding environment.

[0005] To address the aforementioned issues, we have made innovative designs based on the existing low-noise sealed shot blasting machine structure. Utility Model Content

[0006] The purpose of this utility model is to provide a low-noise sealed shot blasting machine to solve the problem mentioned in the background art that the device uses a double-door method to seal the machine body, but when the door slides, there will be a certain gap between it and the outer wall of the machine body. The gap not only allows the noise generated during processing to leak out, but also allows the dust generated during processing to float out through the gap, thereby causing pollution to the surrounding environment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-noise sealed shot blasting machine, comprising a base, wherein shock-absorbing feet are fixedly installed at the bottom of the base; a machine body, wherein the machine body is fixedly installed on the upper end of the base, and a processing cavity is formed on the inner side of the machine body; an adjusting door panel, wherein the adjusting door panel is disposed on the outer side of the machine body; an integrated plate, wherein the integrated plate is disposed on the outer side of the adjusting door panel; a sealing assembly, wherein the sealing assembly is disposed on the outer side of the machine body; and a noise reduction assembly, wherein the noise reduction assembly is disposed between the adjusting door panel and the integrated plate; wherein the sealing assembly is used to drive the adjusting door panel to move up and down; and the noise reduction assembly is used to push the integrated plate to adhere to the outer side of the machine body.

[0008] Preferably, the integrated panel includes a sound insulation board, a sound-absorbing material, and a wear-resistant steel plate. The outer layer of the integrated panel is a sound insulation board, the inner layer is a wear-resistant steel plate, and the space between the sound insulation board and the wear-resistant steel plate is filled with sound-absorbing material.

[0009] Preferably, the sound-absorbing material is a composite layer of polyurethane foam and glass fiber.

[0010] Preferably, the sealing assembly includes a drive motor and a gear, the drive motor is fixedly mounted on the outside of the machine body, and the output end of the drive motor is fixedly connected to the gear.

[0011] Preferably, the sealing assembly further includes a connecting rod and a rack, the connecting rod being fixedly connected to the outside of the adjusting door panel, and the tail end of the connecting rod being fixedly connected to a rack, which meshes with an outer gear.

[0012] Preferably, the sealing assembly further includes a guide groove and a guide block. The guide groove is formed inside the body of the machine body, and the guide block is slidably connected to the inner side of the guide groove. The guide block is connected to the outer adjustment door panel.

[0013] Preferably, the noise reduction component includes a sliding rod, a telescopic spring, and an elastic airbag. The sliding rod is fixedly connected to the outside of the integrated plate, and the tail end of the sliding rod passes through the inside of the adjusting door panel. A telescopic spring is connected between the end of the sliding rod and the adjusting door panel, and an elastic airbag is provided between the integrated plate and the adjusting door panel.

[0014] Preferably, the noise reduction component further includes a compression block, which is fixedly installed on the upper end of the base and has a cone-shaped structure when viewed from the side. The compression block and the elastic airbag are distributed vertically in correspondence.

[0015] Compared with the prior art, the beneficial effect of this utility model is that the low-noise sealed shot blasting machine is equipped with: 1. Noise reduction structure: This structure adopts a three-layer composite noise reduction structure (sound insulation board + sound absorption layer + wear-resistant steel plate), thereby improving the noise reduction effect of shot blasting. The gear and rack driven sealing component realizes precise positioning of the door panel, thereby sealing the inside of the processing cavity and preventing dust from leaking out. 2. Secondary sealing structure: When the door panel moves down, the bottom of the elastic airbag comes into contact with the compression block. The compression block generates a reaction force on the elastic airbag, causing it to expand. The expanded elastic airbag pushes the integrated plate outward, ensuring that the integrated plate fits tightly against the outside of the machine body. This prevents excessive gaps between the integrated plate and the machine body, which could cause dust and noise leakage, thus improving the sealing effect of the machine body.

The sealing component 7 is used to drive the adjusting door panel 5 to move up and down; and the noise reduction component 8 is used to push the integrated plate 6 to fit against the outer side of the machine body 3. The integrated panel 6 includes a sound insulation panel 601, a sound-absorbing material 602, and a wear-resistant steel plate 603. The outer layer of the integrated panel 6 is the sound insulation panel 601, and the inner layer is the wear-resistant steel plate 603. The sound-absorbing material 602 is filled between the sound insulation panel 601 and the wear-resistant steel plate 603. The sound-absorbing material 602 is a composite layer of polyurethane foam and glass fiber. The sealing assembly 7 includes a drive motor 701 and a gear 702. The drive motor 701 is fixedly installed on the outside of the body 3, and the output end of the drive motor 701 is fixedly connected to the gear. 702; The sealing assembly 7 also includes a connecting rod 703 and a rack 704. The connecting rod 703 is fixedly connected to the outside of the adjusting door plate 5, and the rack 704 is fixedly connected to the tail end of the connecting rod 703. The rack 704 meshes with the outer gear 702. The sealing assembly 7 also includes a guide groove 705 and a guide block 706. The guide groove 705 is opened on the inside of the body 3, and the guide block 706 is slidably connected to the inside of the guide groove 705. The guide block 706 is connected to the outer adjusting door plate 5. This integrated panel 6 adopts a three-layer composite noise reduction structure (sound insulation board 601 + sound absorption material 602 + wear-resistant steel plate 603). The wear-resistant steel plate 603 is used to cope with the impact of the shot, the sound absorption material 602 is used to absorb the processing noise, and the sound insulation board 601 is used to isolate the noise, thereby improving the overall wear resistance and noise reduction effect of the integrated panel 6.
