[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: like Figures 1 to 5As shown, this utility model provides a pipe inner wall polishing device, including a polishing frame 1, a polishing mechanism arranged on the top side of the polishing frame 1 for polishing, a control terminal 2 arranged on the polishing frame 1 for controlling the operation of the device, a support and steering mechanism arranged on the top side of the polishing frame 1 for controlling the position and adjusting the direction of the material, a collection mechanism arranged on the polishing frame 1 for collecting dust generated during the polishing process, and a filter mechanism arranged inside the polishing frame 1 for treating air containing dust. The support and steering mechanism further includes a reinforcing component for fixing the material at the top and a driving component for driving the reinforcing component.

[0021] The polishing mechanism includes a linear module 101 arranged on the polishing frame 1, a polishing motor 102 arranged on the polishing frame 1, and a polishing head 103 arranged at the output end of the polishing motor 102 for polishing the inner wall of the material. The linear module 101 and the polishing motor 102 drive the polishing head 103 to polish the inner wall of the material. The collection mechanism includes a conveying pipe 3 arranged at one end of the polishing frame 1 for conveying dust gas generated during the polishing process, a connecting sleeve 301 arranged at the top of the conveying pipe 3 for connecting the conveying pipe 3 and the material, a bracket 302 arranged at the top of the polishing frame 1 for supporting the connecting sleeve 301, and a sealing component arranged at the connection between the connecting sleeve 301 and the material to prevent dust gas leakage.

[0022] The sealing assembly includes an air pump 303 disposed at the top of the conveying pipe 3 for pumping air, and an annular air bladder 304 disposed on the inner wall of the connecting sleeve 301 for sealing the connection between the connecting sleeve 301 and the material. During the grinding process, a large amount of dust will inevitably be generated. The connecting sleeve 301 is connected to the material, and the air pump 303 is used to inject air into the annular air bladder 304 to seal the connection between the material and the conveying pipe 3. When it is necessary to rotate the material, the air in the annular air bladder 304 can be released.

[0023] Example 2: Based on Example 1, the device's adaptability and processing stability are greatly improved through optimized support and steering mechanisms. The combined fixing method of roller support and top roller pressurization, along with an adjustable lifting mechanism, can reliably fix pipe workpieces of different diameters.

[0024] The support and steering mechanism includes a base 5 arranged at the top of the polishing frame 1, a support roller 501 arranged on the base 5 for placing materials, a steering motor 502 arranged on the polishing frame 1 for driving the support roller 501 to rotate, and a bevel gear set 503 arranged between the steering motor 502 and the support roller 501 for transmitting the driving force of the steering motor 502.

[0025] The reinforcement assembly includes a mounting frame 504 arranged on the polishing frame 1, a lifting plate 505 arranged on the bottom side of the mounting frame 504, a rotating rod 506 arranged on the lifting plate 505, and a roller 507 arranged on the rotating rod 506 for squeezing materials.

[0026] The drive assembly includes a limiting rod 508 arranged on the mounting frame 504 and the lifting plate 505 to limit the range of motion of the lifting plate 505. The movement of the lifting plate 505 is limited by the limiting rod 508 and can only move in the vertical direction. A lead screw 509 arranged on the mounting frame 504 and the lifting plate 505 is used to drive the lifting plate 505 to move up and down. A rotating disk 510 arranged at the top of the lead screw 509 is used to drive the lead screw 509 to rotate. The material is supported by the rollers 501. Rotating the rotating disk 510 can drive the lead screw 509 to rotate. The rotating lead screw 509 drives the lifting plate 505 to move up and down, thereby ensuring that the rollers 507 on the rotating rod 506 can contact the material.

[0027] Example 3: Based on Example 1, the annular airbag design in the sealing assembly effectively prevents dust leakage during the suction process. The modular dust collection design (such as collection drawers and filter bags) not only facilitates cleaning and maintenance but also helps to recycle valuable metal waste, realizing resource reuse, reducing production costs, and conforming to the concept of green manufacturing.

[0028] The filtration mechanism includes a filter box 4 (arranged within the polishing frame 1) for filtering large particles in the dusty gas; a filter box 401 (arranged within the polishing frame 1) for filtering small particles in the dusty gas; a negative pressure pump 402 (arranged within the polishing frame 1) for drawing air; the negative pressure pump 402 generates sufficient negative pressure within the polishing frame 1 to draw the dusty gas into the filter box 4 and filter box 401 via the conveying pipe 3; an impact plate 403 (arranged on the inner wall of the filter box 4) to block the flow of dusty gas and cause it to impact; and a connecting pipe (arranged between the filter box 4, filter box 401, and negative pressure pump 402) for connecting the three components. 404, a collection drawer 405 arranged inside filter box 1 for collecting large dust particles, and a collection plate 406 arranged on the collection drawer 405 for impacting dust with impact plate 1 403. Inside filter box 1, impact plate 1 403 and collection plate 2 406 form a curved flow channel, so that dust gas impacts impact plate 1 403 and collection plate 2 406, separating most of the large dust particles, which are then collected by collection drawer 405. A filter bag 407 arranged inside filter box 2 401 for filtering small particles in dust gas. Inside filter box 2 401, filter bag 407 is used to filter the remaining small dust particles, thereby achieving dust purification.

[0029] Working principle: When using this device, the material needs to be placed on the support roller 501, which lifts the material. Rotating the rotating disk 510 drives the lead screw 509 to rotate, which in turn drives the lifting plate 505 to rise and fall. This ensures that the roller 507 on the rotating rod 506 can contact the material. The movement of the lifting plate 505 is restricted by the limit rod 508, allowing it to move only in the vertical direction. The support and steering mechanism is used to position the material, making it adaptable to materials of different specifications and increasing the device's versatility. Then, the linear module 101 and polishing motor 102 drive the polishing head 103 to polish and grind the inner wall of the material. Since a large amount of dust is inevitably generated during the polishing process, the connecting sleeve 301 is connected to the material, and... Air is injected into the annular airbag 304 using an air pump 303, thereby sealing the connection between the material and the conveying pipe 3. When the material needs to be rotated, the air in the annular airbag 304 is released. The negative pressure pump 402 inside the polishing frame 1 will generate sufficient negative pressure, thereby drawing the dust gas through the conveying pipe 3 into the filter box 1 4 and the filter box 2 401. In the filter box 1 4, the impact plate 1 403 and the collection plate 2 406 form a curved flow channel, so that the dust gas collides with the impact plate 1 403 and the collection plate 2 406, separating most of the large dust particles, which are then collected using the collection drawer 405. In the filter box 2 401, the filter bag 407 is used to filter the remaining small dust particles, thereby achieving dust purification.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
