A motor 3 is mounted on the frame 1. The motor 3 is started, and its output end is connected to a deflector 4. The motor 3 rotates, driving the deflector 4 to rotate. A rotating column 5 is arranged on the outer side of the deflector 4. The rotation of the deflector 4 causes the rotating column 5 to rotate and move back and forth simultaneously. A receiving plate 6 is connected to the rotating column 5. The back and forth movement of the rotating column 5 within a certain distance causes the receiving plate 6 to move synchronously. Ten cleaning pipes 7 are connected to the receiving plate 6, allowing the receiving plate 6 to move and receive... The inner side of the plate 6 is slidably connected to a sliding rod 8. The receiving plate 6 is fixed and limited by the sliding rod 8. A spring 9 is provided on the outer side of the sliding rod 8. The spring 9 plays a role in resetting. A moving mechanism 2 is installed on the rear side of the frame 1. The moving mechanism 2 is used to move the mold position for precise docking. A warning sign 10 is provided on the frame 1. A screw 11 is connected to the outer side of the warning sign 10. The warning sign 10 is threadedly connected to the frame 1 through the screw 11. The warning sign 10 plays a warning role. A fixing plate 12 is installed on the motor 3. Support plates 13 are fixedly connected to the bottom front and rear ends of the fixing plate 12. The fixing plate 12 plays a role in fixing the motor 3.

[0032] Specifically, starting motor 3 provides the initial driving force for a series of subsequent mechanical movements. A deflector 4 is connected to the output end of motor 3. Motor 3 drives the deflector 4 to rotate in a circular motion. A rotating column 5 is located on the outer side of the deflector 4. The rotation of the deflector 4 drives the rotating column 5 to rotate while simultaneously moving it back and forth. A receiving plate 6 is connected to the rotating column 5. The back-and-forth movement of the rotating column 5 within a certain distance drives the receiving plate 6 to move synchronously. Ten cleaning pipes 7 are connected to the receiving plate 6. The receiving plate 6 can move the cleaning pipes 7, which are used for cleaning and spraying the mold. As the receiving plate 6 moves, they can reach different positions on the mold, thus achieving treatment of different parts of the mold. A sliding rod 8 is slidably connected to the inner side of the receiving plate 6.

[0033] The support plate 6 provides direction and support for movement, and plays a role in fixing and limiting it, ensuring that the support plate 6 moves back and forth along the direction of the sliding rod 8, avoiding deviation or shaking. A spring 9 is set on the outside of the sliding rod 8, which plays a role in resetting. A moving mechanism 2 is installed on the rear side of the frame 1. The moving mechanism 2 is used to move the mold position for precise docking. A warning sign 10 is set on the frame 1. A screw 11 is connected to the outside of the warning sign 10. The warning sign 10 is threaded to the frame 1 through the screw 11. The warning sign 10 serves to warn the operators and remind them to pay attention to safety during operation to avoid accidents. A fixing plate 12 is installed on the motor 3. The bottom, front and rear ends of the fixing plate 12 are fixedly connected to the support plate 13.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The moving mechanism 2 includes a second motor 201, which is located at the rear end of the frame 1. When the second motor 201 is started, it rotates. A connecting rod 202 is connected to the output end of the second motor 201. The rotation of the second motor 201 drives the connecting rod 202, which is fixed to its output end, to rotate. The connecting rod 202 is rotatably connected to a connecting rod 203, which in turn is rotatably connected to a second connecting rod 204. Therefore, the rotation of the connecting rod 202 drives the connected connecting rod 204 to rotate. The connecting rod 204 is rotatably connected to a second connecting rod 205, which is rotatably connected to a fixed block 206. The forward and backward movement of the connecting rod 204 drives the connected connecting rod 205 to rotate. The connecting rod 205 and the fixing block 206 move back and forth. The fixing block 206 is equipped with a limit rod 207. At the same time, the limit rod 207 at the upper end of the fixing block 206 plays a role in fixing and limiting. Through the above structure, the mold position can be moved quickly, thereby achieving accurate docking. Corner guards 14 are installed at the four corners of the top of the frame 1. The corner guards 14 are connected to the frame 1 by screws 15 through threads. The corner guards 14 are connected to the frame 1 through screws 15 through screws 15 through threads. The corner guards 14 play a protective role. The top of the frame 1 is equipped with a handle 16. The handle 16 is connected to the frame 1 by screws 17 through threads. The handle 16 is connected to the frame 1 through screws 17 through screws 17 through threads. The handle 16 plays a role in facilitating picking up.

[0035] Specifically, starting motor 201 causes it to rotate, serving as the power source. Connecting rod 202 is connected to the output end of motor 201, rotating around its output end. Connecting rod 202 is rotatably connected to connecting rod 203, which in turn is rotatably connected to connecting rod 204. Therefore, the rotation of connecting rod 202 drives the connected connecting rod 204 to rotate. Connecting rod 204 is rotatably connected to connecting rod 205, which is rotatably connected to a fixed block 206. The forward and backward movement of connecting rod 204 causes the connected connecting rod 205 and the fixed block 206 to move forward and backward. The fixed block 206 is equipped with a limit rod 207, which simultaneously serves to fix the fixed block 206, ensuring its stability. There will be no shaking or deviation during the movement; on the other hand, it limits the movement range of the fixed block 206. Through the above structure, the mold position can be moved quickly, thereby achieving accurate docking. Corner guards 14 are installed at the four corners of the top of the frame 1. The corner guards 14 are connected to the frame 1 by screws 15. The corner guards 14 are threaded to the frame 1 by screws 15. When the device is hit by a collision or accidental impact, the corner guards 14 can protect the corner parts of the frame 1 and prevent them from being damaged, thus extending the service life of the frame 1. A handle 16 is installed at the top of the frame 1. The handle 16 is connected to the frame 1 by screws 17. The handle 16 is threaded to the frame 1 by screws 17. The handle 16 facilitates the operator to pick up, carry and move the entire device, improving the convenience and efficiency of operation.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The left and right ends of the handle 16 are connected by threaded rings 18, which facilitate hanging and picking. Multiple limit posts 19 are slidably connected to the inner side of the top wall of the frame 1. Springs 20 are provided on the outer side of the limit posts 19, which serve as positioning posts.

[0037] Specifically, the left and right ends of the handle 16 are connected to hanging rings 18 by threads. The presence of hanging rings 18 provides convenience for the storage and transportation of the device. When it is necessary to hang the device in a specific position, such as on a hook on the wall or on the crossbar of a storage rack, the two hanging rings 18 can be used to easily hang and operate, which can improve space utilization and facilitate the management and retrieval of the equipment. Multiple limiting posts 19 are slidably connected to the inner side of the top wall of the frame 1. Springs 20 are set on the outer side of the limiting posts 19. The function of the limiting posts 19 is to position. During the use of the equipment, some parts need to be accurately placed in a specific position. At this time, the limiting posts 19 can play a guiding and fixing role.

[0038] Working principle: Start motor 3. Motor 3 drives the deflector 4 at the output end to rotate by its own rotation. The rotation of the deflector 4 drives the rotating column 5 in contact to rotate and move back and forth at the same time. The rotating column 5 moves back and forth within a certain distance, driving the receiving plate 6 to move synchronously. Since there are multiple cleaning tubes 7 on the top of the receiving plate 6, the receiving plate 6 can drive the cleaning tubes 7 to move. At the same time, the receiving plate 6 is fixed and limited by the sliding rod 8. The spring 9 at the rear end of the sliding rod 8 plays a reset role. Through the above structure, the gaps and dead corners in the combined mold for molding high molecular weight polyethylene sheets are cleaned.

[0039] When motor 201 is started, it rotates, causing connecting rod 202, which is fixed at its output end, to rotate. Since connecting rod 202 is connected to connecting rod 204 via connecting rod 203, the rotation of connecting rod 202 can drive the connected connecting rod 204 to rotate. At the same time, connecting rod 204 can also move back and forth within a certain distance. The back and forth movement of connecting rod 204 drives the connected connecting rod 205 and the fixing block 206 to move back and forth. Meanwhile, the limiting rod 207 at the upper end of the fixing block 206 plays a role in fixing and limiting. Through the above structure, the mold position can be moved quickly, thereby achieving accurate docking.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
