When the PVC pipe needs to be removed from the movable frame 3, the second driving component 6 is operated to move the movable splint 52 away from the fixed bracket to release the clamping of the PVC pipe; the cleaning tank 2 is also provided with a flushing component 7, which includes a plurality of nozzles 71 and the nozzles 71 are respectively located on opposite sides of the movable frame 3 and facing the clamping component 5. The nozzles 71 are used to spray cleaning liquid on the PVC pipe clamped on the clamping component 5 to flush the PVC pipe, ensuring that dust and dirt attached to the PVC pipe are effectively removed.

[0025] Specifically, the operating steps of cleaning PVC pipes using the PVC pipe cleaning device provided in this embodiment are as follows: first, the first driving component 4 drives the movable frame 3 to rotate to the position where the clamping component 5 exits the cleaning tank 2, and then one end of the PVC pipe to be cleaned is inserted into the slot 53 on the fixed splint 51. After the PVC pipe is placed, the second driving component 6 is operated to make the movable splint 52 close to the fixed splint 51 so that the other end of the PVC pipe is inserted into the slot 53 on the movable splint 52, and the PVC pipe can be fixed on the movable frame 3. The first driving component 4 then drives the movable frame 3 to rotate to place the clamping component 5 together with the PVC pipe into the cleaning tank 2 and The PVC pipe is immersed in the cleaning liquid in the cleaning tank 2, and the first driving component 4 drives the movable frame 3 to swing back and forth so that the PVC pipe moves back and forth in the cleaning liquid. At the same time, the nozzle 71 sprays the cleaning liquid on the PVC pipe to rinse the PVC pipe to ensure that the PVC pipe is clean. After cleaning, the first driving component 4 drives the movable frame 3 to rotate so that the clamping component 5 withdraws from the cleaning tank 2. The PVC pipe is placed on the movable frame 3 for a period of time to drain the PVC pipe. The second driving component 6 is operated to move the movable splint 52 away from the fixed splint 51. At this time, the two ends of the cleaned PVC pipe are respectively pulled out of the slot 53 to remove the PVC pipe from the PVC pipe cleaning device. The PVC pipe cleaning device provided in this embodiment simplifies the operating steps for cleaning PVC pipes. During the process of clamping and removing the PVC pipe, the PVC pipe cleaning device does not need to be disassembled and assembled, which shortens the time required for clamping and removing the PVC pipe. The operation is simple and convenient, which is conducive to improving the cleaning efficiency of the PVC pipe.

[0026] like Figure 2 and Figure 4As shown, the first driving assembly 4 includes a first link 41 and a second link 42 that are respectively rotatably connected to the frame 1, the end of the first link 41 away from the frame 1 is rotatably connected to the third link 43, and the end of the third link 43 away from the first link 41 is rotatably connected to the movable frame 3, the third link 43 is rotatably connected to the second link 42, the end of the second link 42 away from the frame 1 is rotatably connected to the fourth link 44, and the end of the fourth link 44 away from the second link 42 is rotatably connected to the movable frame 3. The first driving assembly 4 includes a connecting rod mechanism consisting of the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44. When the first connecting rod 41 rotates relative to the frame 1, the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 cooperate to drive the movable frame 3 to rotate relative to the frame 1, so that the movable frame 3 moves along a preset trajectory and flips, so that the movable frame 3 can be driven by the first driving assembly 4 to move to a position where the clamping assembly 5 is placed in the cleaning tank 2, ensuring that the PVC pipe clamped to the movable frame 3 is completely placed in the cleaning tank 2, and after cleaning is completed, the movable frame 3 is moved to a position where the clamping assembly 5 is exposed, so as to facilitate the removal of the PVC pipe on the movable frame 3.

[0027] In this embodiment, the first drive assembly 4 further includes a cylinder 45 and a telescopic rod 46 disposed at the output end of the cylinder 45.

By driving the telescopic rod 46 to extend or retract the cylinder 45, the cylinder 45 can drive the first connecting rod 41 to rotate relative to the frame 1 through the action of the telescopic rod 46. The power output from the cylinder 45 is transmitted to the movable frame 3 via a linkage mechanism consisting of the first connecting rod 41, the second connecting rod 42, the third connecting rod 43, and the fourth connecting rod 44, thereby driving the movable frame 3 to rotate relative to the frame 1, thereby improving the stability of the movable frame 3 during movement.

[0028] Please refer to Figure 3The movable frame 3 is further provided with a guide rod 31, the axial direction of which is consistent with the moving direction of the movable splint 52, and the movable splint 52 is provided with a guide hole that cooperates with the guide rod 31. The provision of the guide rod 31 on the movable frame 3 and the provision of the guide hole that cooperates with the guide rod 31 on the movable splint 52 ensure a reliable connection between the movable splint 52 and the movable frame 3, preventing the movable splint 52 from falling off the movable frame 3 during movement. The guide rod 31 guides the movement of the movable splint 52, ensuring that the movable splint 52 moves in a predetermined direction and smoothly cooperates with the PVC pipe placed on the movable frame 3.

[0029] Please combine Figure 3 and Figure 4 The movable frame 3 is also provided with a mounting seat 32, the mounting seat 32 is provided with a threaded hole, and the axial direction of the threaded hole is consistent with the moving direction of the movable splint 52, the second driving component 6 includes an adjusting screw 61 that cooperates with the threaded hole, and one end of the adjusting screw 61 abuts against the side of the movable splint 52 away from the fixed splint 51. By providing the threaded hole on the mounting seat 32 for the installation of the adjusting screw 61, the adjusting screw 61 moves along the axial direction of the threaded hole when it is rotated, and the movable splint 52 can be pushed to move on the movable frame 3 by the movement of the adjusting screw 61, and the movable splint 52 is pressed against the movable splint 52 by the adjusting screw 61 to keep the movable splint 52 in a position abutting against the PVC pipe, so that the position of the PVC pipe between the fixed splint 51 and the movable splint 52 remains stable. When the PVC pipe needs to be removed, the adjusting screw 61 is rotated in the reverse direction to move the adjusting screw 61 away from the fixed splint 51, so that the movable splint 52 can be moved in the direction away from the fixed splint 51 to release the clamping of the PVC pipe. The operation is simple and convenient.

[0030] In detail, the second drive assembly 6 further includes an adjustment handwheel 62, which is located at the end of the adjustment screw 61 away from the movable clamping plate 52. The adjustment handwheel 62 is provided on the adjustment screw 61, and the adjustment handwheel 62 can be operated to conveniently rotate the adjustment screw 61 and adjust the position of the adjustment screw 61, thereby facilitating adjustment of the position of the movable clamping plate 52 and conveniently controlling the clamping assembly 5 to clamp or release the PVC pipe.

[0031] like Figure 3As shown, the fixed plate 51 and the movable plate 52 are each provided with a through-hole 54 extending therethrough, and the through-hole 54 is in communication with the slot 53. By providing the through-holes 54 in communication with the slot 53 on the fixed plate 51 and the movable plate 52, respectively, when the PVC pipe is immersed in cleaning liquid, the cleaning liquid can sequentially pass through the through-holes 54 and the slot 53 and penetrate into the interior of the PVC pipe, thereby cleaning the interior of the PVC pipe. This allows the PVC pipe cleaning device to simultaneously clean both the interior and exterior of the PVC pipe.

[0032] Specifically, the clamping assembly 5 further includes a support plate 55, which is located between the fixed clamping plate 51 and the movable clamping plate 52 and is provided with a positioning groove 56. The support plate 55 is used to support and position the PVC pipe placed on the movable frame 3. After one end of the PVC pipe is inserted into the slot 53 on the fixed clamping plate 51, the PVC pipe fits against the inner wall of the positioning groove 56, thereby maintaining a stable position of the PVC pipe between the fixed clamping plate 51 and the movable clamping plate 52, making it easier to operate the movable clamping plate 52 to clamp the PVC pipe.

[0033] like Figure 1 and Figure 4 As shown, in this embodiment, the flushing assembly 7 further includes a water tank, a water pump, and a conduit 72, which are sequentially connected. The conduit 72 is connected to the nozzle 71 at one end away from the water pump. The water tank is used to store cleaning liquid or water. The water pump pumps the cleaning liquid or water in the water tank along the conduit 72 into the nozzle 71. The cleaning liquid or water is then sprayed toward the PVC pipe through the nozzle 71 to flush the PVC pipe, thereby effectively removing dust or dirt attached to the PVC pipe and ensuring that the PVC pipe cleaning device has a good cleaning effect.

[0034] In detail, the flushing assembly 7 further includes a filter connected to the water tank, and the filter is connected to the cleaning tank 2. The filter is arranged between the water tank and the cleaning tank 2 to filter the water entering the water tank from the cleaning tank 2.
