[0002] At present, the Chinese utility model with the announcement number CN211435643U discloses a dust and odor removal device suitable for silicon wafer cutting equipment. Although the dust removal device can purify dust and odor through the air filter plate, there are still other problems in the use process, such as poor self-stability, the device is directly hung on the machine table during use, and the side with the air suction port is aligned with the cutting direction. Although it is convenient to take and place, when the machine table is collided or manually pushed, the device is prone to displacement and falling, the safety is poor, and the shock absorption and noise reduction effect is poor. The fan inside the device will produce strong vibration during operation, and the fan vibration energy will be transmitted to the workbench in contact with the shell, which not only produces loud noise, but also affects the normal work of personnel. In order to solve the above problems, we propose a dust removal device of cutting machine workbench. UTILITY MODEL CONTENTS

[0016] The utility model has the advantages of the following:

[0017] 1. The utility model discloses a shell is first lifted and makes its front end lean on the workbench, then the shell is pushed forward to make the table top be located between the shell and the clamping plate, then the handle is held and the screw rod is rotated, the screw rod is rotated and drives the clamping plate to move up through the cooperation of the slide rail and the slide block, the clamping plate is clamped on the table top in cooperation with the shell when moving up, the stability between the workbench can be improved, the operation is simple and convenient, the device is prevented from shifting and falling during use, and the safety is high.

[0018] 2. This utility model utilizes a suction fan. After startup, the suction fan draws the dust-laden gas generated during cutting into the housing through the suction port. The air filter plate inside the housing intercepts and adsorbs impurities and particulate matter in the gas. Finally, the gas is discharged outward from the exhaust port. When the suction fan vibrates, it causes the mounting plate to move downward. As the mounting plate moves downward, it presses against the fixing spring and damper. When the fixing spring and damper deform under pressure, they absorb and weaken the vibration energy, achieving good vibration reduction and noise reduction effects, avoiding interference with operators, improving the working environment, and demonstrating high practicality.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1:

[0026] refer to Figure 1 and Figure 2 A dust removal device for a cutting machine workbench includes a housing 1. A baffle 17 and a fixing plate 2 are respectively bolted to the front and one side of the housing 1. A threaded rod 3 is rotatably connected to the inside of the housing 1 via a bearing. A clamping plate 4 is threadedly connected to the surface of the threaded rod 3. The housing 1 is first lifted so that its front end rests against the workbench. Then, the housing 1 is pushed forward so that the workbench is positioned between the housing 1 and the clamping plate 4. The handle 5 is then held by hand to rotate the threaded rod 3. When the threaded rod 3 rotates, it will drive the clamping plate 4 to move upward through the cooperation of the slide rail 13 and the slider 14. When the clamping plate 4 moves upward, it will clamp the housing 1 onto the workbench, which can improve the stability between the device and the workbench. The operation is simple and convenient, and it can prevent the device from shifting or falling during use, thus ensuring high safety.

[0027] refer toFigure 2 The housing 1 has a slide rail 13 bolted inside, and a slider 14 that is slidably connected to the slide rail 13 is welded to one side of the clamping plate 4. The slide rail 13 and the slider 14 can limit the clamping plate 4 and prevent it from flipping over during the up and down movement.

[0028] refer to Figure 2 The bottom end of the threaded rod 3 extends through to the bottom of the fixed plate 2 and is welded with a handle 5. The handle 5 allows personnel to easily rotate the threaded rod 3.

[0029] Brief description of the usage process: First, lift the housing 1 so that its front end rests against the worktable. Then, push the housing 1 forward so that the table is between the housing 1 and the clamping plate 4. Then, hold the throttle 5 and rotate the threaded rod 3. When the threaded rod 3 rotates, it will drive the clamping plate 4 to move upward through the cooperation of the slide rail 13 and the slider 14. When the clamping plate 4 moves upward, it will cooperate with the housing 1 to clamp on the table.

[0030] Example 2:

[0031] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A dust removal device for a cutting machine workbench includes a mounting plate 6 inside a housing 1. A suction fan 7 is bolted to the top of the mounting plate 6. A fixing spring 8 is bolted between the bottom of the mounting plate 6 and the housing 1 via a spring fixing plate. A damper 9 is installed between the bottom of the mounting plate 6 and the housing 1. An air filter plate 10 is installed on the top of the suction fan 7. An air intake 11 and an air exhaust 12 are respectively opened on one side and the bottom of the housing 1. By starting the suction fan 7, the dust generated during cutting will be removed through the air intake 11. Dust-laden gas is drawn into the housing 1. The air filter 10 inside the housing 1 intercepts and adsorbs impurities and particulate matter in the gas. Finally, the gas is discharged outward from the exhaust port 12. When the suction fan 7 vibrates, it will drive the mounting plate 6 to move downward. When the mounting plate 6 moves downward, it will press the fixing spring 8 and the damper 9. When the fixing spring 8 and the damper 9 are deformed under pressure, they will absorb and weaken the vibration energy, which can achieve good vibration reduction and noise reduction effect, avoid interference to operators, improve the working environment, and have high practicality.

[0032] refer to Figure 2 and Figure 3 Both sides of the air filter plate 10 are secured with a retainer 15, and the other side of the retainer 15 is bolted to the inside of the housing 1. The retainer 15 can limit the air filter plate 10 and prevent it from tilting or falling after being inserted.

[0033] refer to Figure 2A dustproof net 16 is attached to the bottom of the housing 1. The inner diameter of the dustproof net 16 is larger than the diameter of the exhaust port 12. The dustproof net 16 can prevent dust from entering the fan 7 from the exhaust port 12.

[0034] refer to Figure 4 The fixed spring 8 is made of carbon spring steel and has excellent mechanical properties, good spring damping performance, low temperature resistance and corrosion resistance.

[0035] Brief description of the usage process: By starting the suction fan 7, the suction fan 7 will draw the dust-laden gas generated during cutting into the housing 1 through the suction port 11. The air filter plate 10 inside the housing 1 will intercept and adsorb impurities and particulate matter in the gas. Finally, the gas will be discharged outward from the exhaust port 12. When the suction fan 7 vibrates, it will drive the mounting plate 6 to move downward. When the mounting plate 6 moves downward, it will press against the fixing spring 8 and the damper 9. When the fixing spring 8 and the damper 9 are deformed under pressure, they will absorb and weaken the vibration energy.
