[0036] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0037] Please refer to the reference. Figures 1 to 3 This invention provides a pipe cleaning device 100 for cleaning pipes 400. It enables automated cleaning of pipes 400, with a high degree of mechanization, saving time and labor, achieving high cleaning efficiency and good cleaning results.

[0038] The pipe cleaning device 100 includes a frame 110, a first rotating roller 120, a second rotating roller 130, a brush roller 140, a sealing chamber 150, and a vacuum pump 160. The first rotating roller 120 and the second rotating roller 130 are arranged side-by-side and rotatably mounted on the frame 110. The first rotating roller 120 and the second rotating roller 130 jointly support the pipe 400 and drive the pipe 400 to rotate around its axial direction. In this embodiment, the pipe 400, the first rotating roller 120, and the second rotating roller 130 all extend horizontally. The pipe 400 is placed between the first rotating roller 120 and the second rotating roller 130. During rotation, the first rotating roller 120 and the second rotating roller 130 drive the pipe 400 to rotate synchronously through friction with it.

[0039] It should be noted that a gap 170 is formed between the first rotating roller 120 and the second rotating roller 130. The brush roller 140 is arranged parallel to and spaced apart from the first rotating roller 120, and is partially disposed within the gap 170. The brush roller 140 is used to clean the outer peripheral wall of the pipe 400. Specifically, the brush roller 140 disposed within the gap 170 is always in contact with the outer peripheral wall of the pipe 400. During the rotation of the pipe 400 driven by the first rotating roller 120 and the second rotating roller 130, the pipe 400 rotates relative to the brush roller 140, so that the brush roller 140 can clean the entire outer peripheral wall of the pipe 400.

[0040] Furthermore, the sealing chamber 150 is connected to the frame 110 and is located below the roller gap 170. One end of the sealing chamber 150 is connected to the roller gap 170, and the other end is connected to the vacuum pump 160. The vacuum pump 160 is used to generate negative pressure to draw air from the roller gap 170 into the sealing chamber 150 and to extract the air from the sealing chamber 150 outward. During this process, the vacuum pump 160 can adsorb the pipe 400 onto the first rotating roller 120 and the second rotating roller 130 through the gap 170 between the rollers, thereby increasing the friction between the pipe 400 and the first rotating roller 120 and the second rotating roller 130. This ensures that the first rotating roller 120 and the second rotating roller 130 can drive the pipe 400 to rotate synchronously, preventing the pipe 400 from slipping relative to the first rotating roller 120 and the second rotating roller 130, ensuring stability and reliability. The vacuum pump 160 can also remove debris (waste chips or dust) swept off the outer peripheral wall of the pipe 400 to prevent debris from scattering everywhere, avoiding environmental pollution, and improving the cleaning effect. In this way, automatic dust removal is performed simultaneously with automatic cleaning of the outer peripheral wall of the pipe 400, achieving automated cleaning of the pipe 400. This process is highly mechanized, saves time and labor, has high cleaning efficiency, and provides excellent cleaning results.

[0041] In this embodiment, the pipe cleaning device 100 further includes a drive mechanism 180. The drive mechanism 180 is connected to the first rotating roller 120, the second rotating roller 130, and the brush roller 140 to drive them to rotate. The first rotating roller 120 and the second rotating roller 130 rotate in the same direction, while the brush roller 140 rotates in the opposite direction. Specifically, during the cleaning of the outer peripheral wall of the pipe 400, the first rotating roller 120 and the second rotating roller 130 drive the pipe 400 to rotate in a first direction under the action of the drive mechanism 180, and the brush roller 140 rotates in a second direction under the action of the drive mechanism 180. The first direction and the second direction are opposite to each other, so as to enhance the cleaning effect of the brush roller 140 on the outer peripheral wall of the pipe 400 and improve the cleaning efficiency.

[0042] The drive mechanism 180 includes a first drive motor 181, an output wheel 182, and a transmission belt 183. The first drive motor 181 is connected to the output wheel 182 and can drive the output wheel 182 to rotate. The output wheel 182 is simultaneously connected to the first rotating roller 120, the second rotating roller 130, and the brush roller 140 via the transmission belt 183. During rotation, the output wheel 182 drives the transmission belt 183 to move through the friction between itself and the transmission belt 183. During movement, the transmission belt 183 synchronously drives the first rotating roller 120, the second rotating roller 130, and the brush roller 140 to rotate through the friction between itself and the first rotating roller 120, the second rotating roller 130, and the brush roller 140. Specifically, the first rotating roller 120 and the second rotating roller 130 are both attached to the inner side of the transmission belt 183, and the brush roller 140 is attached to the outer side of the transmission belt 183, so that the first rotating roller 120 and the second rotating roller 130 rotate in the same direction, and the brush roller 140 rotates in the opposite direction.

[0043] Please refer to the reference. Figures 3 to 5 In this embodiment, the pipe cleaning device 100 further includes a first lifting mechanism 190, a positioning seat 200, a second lifting mechanism 210, and a mounting frame 220. The first lifting mechanism 190 is mounted on the frame 110 and connected to the positioning seat 200. The brush roller 140 is rotatably mounted on the positioning seat 200. The first lifting mechanism 190 is used to drive the brush roller 140 to rise or fall through the positioning seat 200 to adjust the height position of the brush roller 140, so that the brush roller 140 can contact the outer peripheral wall of pipes 400 with different diameters, thereby realizing the cleaning function of pipes 400 with different diameters and having a wide range of applications.

[0044] Furthermore, the second lifting mechanism 210 is mounted on the frame 110 and connected to the mounting bracket 220, and the first drive motor 181 is mounted on the mounting bracket 220. The second lifting mechanism 210 is used to drive the first drive motor 181 to descend via the mounting bracket 220 when the brush roller 140 rises, or to drive the first drive motor 181 to rise via the mounting bracket 220 when the brush roller 140 descends, so as to ensure the tension of the transmission belt 183. Specifically, the axis of the brush roller 140 and the axis of the output wheel 182 are located on the same vertical plane, and the output wheel 182 is located directly below the brush roller 140. When the first lifting mechanism 190 drives the brush roller 140 to rise via the positioning seat 200, the brush roller 140 moves in the direction of extending into the gap 170 between the rollers, and the transmission belt 183 gradually loosens. At this time, the second lifting mechanism 210 drives the first drive motor 181 to descend via the mounting frame 220, thereby driving the output wheel 182 to descend, thus tightening the transmission belt 183 and ensuring the tension of the transmission belt 183, thereby ensuring the stability of the transmission. When the first lifting mechanism 190 drives the brush roller 140 to descend via the positioning seat 200, the brush roller 140 moves in the direction of retracting out of the gap 170 between the rollers, and the transmission belt 183 gradually tightens. At this time, the second lifting mechanism 210 drives the first drive motor 181 to rise via the mounting frame 220, thereby driving the output wheel 182 to rise, thereby loosening the transmission belt 183 and ensuring the tension of the transmission belt 183, thereby ensuring the stability of the transmission.

[0045] In this embodiment, there are two first lifting mechanisms 190 and two positioning seats 200. Each first lifting mechanism 190 is connected to one positioning seat 200. The two positioning seats 200 are arranged opposite to each other at both ends of the brush roller 140. The two first lifting mechanisms 190 lift and lower synchronously so that both ends of the brush roller 140 lift and lower synchronously, ensuring that the brush roller 140 always extends in the horizontal direction, thereby ensuring the cleaning effect.

[0046] Please refer to Figure 6It is worth noting that the first rotating roller 120 has a plurality of first annular grooves 121 on its circumferential surface, and the plurality of first annular grooves 121 are arranged in parallel and spaced apart; the second rotating roller 130 has a plurality of second annular grooves 131 on its circumferential surface, and the plurality of second annular grooves 131 are arranged in parallel and spaced apart. Specifically, the first annular groove 121 is used to increase the friction between the first rotating roller 120 and the pipe 400, so as to ensure that the first rotating roller 120 can stably drive the pipe 400 to rotate and prevent the pipe 400 from displacing relative to the first rotating roller 120 along its axial direction; the second annular groove 131 is used to increase the friction between the second rotating roller 130 and the pipe 400, so as to ensure that the second rotating roller 130 can stably drive the pipe 400 to rotate and prevent the pipe 400 from displacing relative to the second rotating roller 130 along its axial direction; the first annular groove 121 and the second annular groove 131 are also used to allow outside air to flow into the roller gap 170, so that the vacuum pump 160 has enough air to enter the sealing chamber 150 from the roller gap 170 during operation, preventing the pipe 400 from blocking the roller gap 170, ensuring air circulation, thereby ensuring that the vacuum pump 160 can operate continuously and stably, and improving the adsorption effect on the pipe 400 and the removal effect on impurities.

[0047] In this embodiment, the pipe cleaning device 100 further includes a first cover plate 230 and a second cover plate 240. Both the first cover plate 230 and the second cover plate 240 are detachably connected to the frame 110 and are both positioned above the first rotating roller 120 and the second rotating roller 130. The first cover plate 230 and the second cover plate 240 are positioned opposite each other at both ends of the first rotating roller 120, forming a receiving cavity 310 between them. The receiving cavity 310 communicates with the roller gap 170. The receiving cavity 310 is used to receive the pipe 400. The first cover plate 230 and the second cover plate 240 are used to limit the pipe 400 to prevent displacement along its axial direction. The first cover plate 230 and the second cover plate 240 also serve a sealing function, ensuring that outside air can only enter the roller gap 170 through the receiving cavity 310, and then flow into the sealing chamber 150 under the action of the vacuum pump 160.

[0048] Furthermore, the length of the first rotating roller 120 is equal to the length of the second rotating roller 130 and greater than the length of the first cover plate 230, and the length of the first cover plate 230 is equal to the length of the second cover plate 240. Specifically, there are multiple first cover plates 230 and multiple second cover plates 240, each with a different length. When cleaning pipes 400 of different lengths, it is necessary to select first cover plates 230 and second cover plates 240 of appropriate lengths to ensure that the length of the accommodating cavity 310 matches the length of the pipe 400, thereby ensuring the limiting and sealing effects and making it widely applicable.

[0049] In this embodiment, the pipe cleaning device 100 further includes a first brush head 250 and a second brush head 260. The first brush head 250 is installed at one end of the first cover plate 230 near the accommodating cavity 310, and the second brush head 260 is installed at one end of the second cover plate 240 near the accommodating cavity 310. The first brush head 250 and the second brush head 260 are respectively used to clean the two end walls of the pipe 400 to enhance the cleaning effect. Specifically, during the process of the first rotating roller 120 and the second rotating roller 130 driving the pipe 400 to rotate, one end of the pipe 400 rotates relative to the first brush head 250, and the other end rotates relative to the second brush head 260. During this process, the first brush head 250 and the second brush head 260 work together to simultaneously clean the two end walls of the pipe 400, resulting in a good cleaning effect.

[0050] Furthermore, there are two of each of the first brush head 250 and the second brush head 260 to improve the cleaning efficiency of the end wall of the pipe 400. Specifically, the two first brush heads 250 are spaced apart along the width direction of the first cover plate 230, with one first brush head 250 positioned above the first rotating roller 120 and the other first brush head 250 positioned above the second rotating roller 130; the two second brush heads 260 are spaced apart along the width direction of the second cover plate 240, with one second brush head 260 positioned above the first rotating roller 120 and the other second brush head 260 positioned above the second rotating roller 130.

[0051] In this embodiment, the pipe cleaning device 100 further includes an electrostatic bar 270, which is mounted on the frame 110 and is arranged parallel to and spaced apart from the first rotating roller 120. The electrostatic bar 270 is arranged parallel to and spaced apart from the pipe 400 placed on the first rotating roller 120 and the second rotating roller 130. The electrostatic bar 270 is used to eliminate static electricity on the pipe 400 to prevent debris from being attracted to the pipe 400 due to static electricity, thereby enhancing the cleaning effect.

[0052] Please refer to the reference. Figure 1 , Figure 4 and Figure 7In this embodiment, the pipe cleaning device 100 further includes an inner wall cleaning mechanism 280, which includes a fixed frame 281, a drive assembly 282, a brush rod 283, and a suction pipe 284. The brush rod 283 is slidably mounted on the fixed frame 281. The drive assembly 282 is mounted on the fixed frame 281 and connected to the brush rod 283. The brush rod 283 is parallel to the first rotating roller 120 and coaxially arranged with the pipe 400, and contacts the inner peripheral wall of the pipe 400. The drive assembly 282 is used to drive the brush rod 283 to slide along its axial direction to extend into or retract from the pipe 400. The brush rod 283 is used to clean the inner peripheral wall of the pipe 400. Specifically, as the first rotating roller 120 and the second rotating roller 130 drive the pipe 400 to rotate, the brush rod 283 gradually extends into the pipe 400. During this process, the inner peripheral wall of the pipe 400 rotates relative to the brush rod 283, and the brush rod 283 can clean the inner peripheral wall of the pipe 400. As the brush rod 283 extends, it can clean the inner peripheral wall of the pipe 400 at different length positions, ensuring the cleaning effect.

[0053] The drive assembly 282 includes a second drive motor 2821, a drive wheel 2822, a conveyor belt 2823, and a driven wheel 2824. The second drive motor 2821 is mounted on a fixed frame 281 and connected to the drive wheel 2822. The drive wheel 2822 is connected to the driven wheel 2824 via the conveyor belt 2823. The driven wheel 2824 is rotatably mounted on the fixed frame 281. The conveyor belt 2823 is connected to the brush rod 283. Specifically, the second drive motor 2821 can drive the drive wheel 2822 to rotate, thereby driving the driven wheel 2824 to rotate via the conveyor belt 2823. During this process, the conveyor belt 2823 synchronously drives the brush rod 283 to move, so that the brush rod 283 extends into or retracts from the pipe 400 along its axial direction.

[0054] Please refer to Figure 8The brush rod 283 includes a rod body 2831, a mounting spindle 2832, an end plate 2833, and brush blades 2834. The rod body 2831 is slidably engaged with the fixed frame 281 and connected to the conveyor belt 2823 of the drive assembly 282. The rod body 2831 is coaxially arranged with the pipe 400 and can slide relative to the fixed frame 281 along its axial direction under the action of the conveyor belt 2823. The mounting spindle 2832 is coaxially arranged with the rod body 2831. One end of the mounting spindle 2832 is connected to the end plate 2833, and the other end is connected to the rod body 2831. A mounting groove 2835 is formed on the circumferential surface of the mounting spindle 2832. The brush blade 2834 is installed in the mounting groove 2835 and positioned between the end plate 2833 and the rod body 2831. The brush blade 2834 is used to contact the inner circumferential wall of the pipe 400 to achieve the cleaning function of the inner circumferential wall of the pipe 400. Specifically, the mounting groove 2835 can hold and fix the brush blade 2834. The end plate 2833 and the rod body 2831 work together to limit the movement of the brush blade 2834, preventing it from detaching from the mounting spindle 2832 and ensuring the stability of cleaning the inner circumferential wall of the pipe 400.

[0055] In this embodiment, there are three brush blades 2834 and three mounting slots 2835. Each brush blade 2834 is engaged in one mounting slot 2835. The three mounting slots 2835 are arranged in a circular array on the circumferential surface of the mounting mandrel 2832. The three brush blades 2834 work together to improve the cleaning efficiency and enhance the cleaning effect on the inner circumferential wall of the pipe 400. However, this is not the only embodiment. In other embodiments, the number of brush blades 2834 and four mounting slots 2835 can be two or four. The number of brush blades 2834 and mounting slots 2835 is not specifically limited.

[0056] It should be noted that a suction port 2836 is provided at one end of the rod 2831 near the mounting spindle 2832, and a suction channel 2837 is provided inside the rod 2831. The diameter of the mounting spindle 2832 is smaller than the diameter of the rod 2831 to facilitate the opening of the suction port 2836. One end of the suction channel 2837 is connected to the suction port 2836, and the other end is connected to the sealing chamber 150 through the suction pipe 284. The vacuum pump 160 is used to generate negative pressure to sequentially draw air from the pipe 400 into the suction port 2836, the suction channel 2837, and the sealing chamber 150, and to extract air from the sealing chamber 150. During this process, the vacuum pump 160 can remove debris swept off the inner wall of the pipe 400 through the suction pipe 284 and the suction channel 2837 to prevent debris from flying out of the pipe 400, avoid environmental pollution, and improve the cleaning effect.

[0057] In this embodiment, there are three suction ports 2836 arranged in a circular array to improve suction efficiency and enhance suction effect. However, this is not the only embodiment; in other embodiments, the number of suction ports 2836 may be two or four, and the number of suction ports 2836 is not specifically limited.

[0058] Please continue to refer to Figure 1 In this embodiment, the pipe cleaning device 100 further includes a third lifting mechanism 290 and a support frame 300. The third lifting mechanism 290 is mounted on the frame 110 and connected to the support frame 300. The support frame 300 is connected to the fixed frame 281. The third lifting mechanism 290 is used to drive the fixed frame 281 to rise or fall through the support frame 300, thereby adjusting the height of the entire inner wall cleaning mechanism 280. This allows the brush rod 283 to contact the inner circumferential wall of pipes 400 with different diameters, thus achieving the cleaning function for pipes 400 with different diameters and having a wide range of applications.

[0059] In this embodiment, the first lifting mechanism 190, the second lifting mechanism 210, and the third lifting mechanism 290 are all electric cylinders, but they are not limited to this. In other embodiments, the first lifting mechanism 190, the second lifting mechanism 210, and the third lifting mechanism 290 can all be hydraulic cylinders or pneumatic cylinders. The driving method of the first lifting mechanism 190, the second lifting mechanism 210, and the third lifting mechanism 290 is not specifically limited.

[0060] The pipe cleaning device 100 provided in this embodiment of the invention has a first rotating roller 120 and a second rotating roller 130 arranged side by side, both of which are rotatably mounted on a frame 110. The first rotating roller 120 and the second rotating roller 130 are used to jointly support the pipe 400 and drive the pipe 400 to rotate around its axial direction. A roller gap 170 is formed between the first rotating roller 120 and the second rotating roller 130. A brush roller 140 is arranged parallel to and spaced apart from the first rotating roller 120, and is partially disposed in the roller gap. Within the gap 170, the brush roller 140 is used to clean the outer peripheral wall of the pipe 400. The sealing chamber 150 is connected to the frame 110 and is located below the roller gap 170. One end of the sealing chamber 150 is connected to the roller gap 170, and the other end is connected to the vacuum pump 160. The vacuum pump 160 is used to adsorb the pipe 400 onto the first rotating roller 120 and the second rotating roller 130 through the roller gap 170. The vacuum pump 160 is also used to remove debris from the outer peripheral wall of the pipe 400. Compared with the prior art, the pipe cleaning device 100 provided by the present invention, due to the use of the brush roller 140 partially disposed within the roller gap 170 and the vacuum pump 160 connected to the roller gap 170 through the sealing chamber 150, can achieve automated cleaning of the pipe 400, with a high degree of mechanization, saving time and labor, high cleaning efficiency, and good cleaning effect.
