DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: a traction device for plastic pipe extrusion molding, including a traction machine body 1 and moving wheels 2. Rotatable moving wheels 2 are arranged on the outer side of the lower surface of the traction machine body 1. Due to the rotatability of the four groups of moving wheels 2, the device realizes the function of being movable, which facilitates the staff to move the device to any working position according to the working requirements, saving time and effort, improving the convenience of the device during use, and facilitating the staff to use the device. A connection groove 3 is opened on the outer side surface of the traction machine body 1, and a limiting hole 4 is opened on the inner wall of the connection groove 3. A first support plate 5 is fixedly connected to the rear side of the upper surface of the traction machine body 1. A fixing plate 6 is fixedly connected to the bottom of the back surface of the first support plate 5. A driving motor 7 is fixedly connected to the upper surface of the fixing plate 6. The driving motor 7 can drive the winding roller 8 to wind the plastic pipe drawn out by the traction machine body 1. After the winding is completed, control the limiting rod 12 to move out of the inside of the limiting hole 4, indirectly enabling the second support plate 9 to release the shielding of the outer surface of the winding roller 8. Then the staff can remove the coiled plastic pipe on the surface of the winding roller 8, thus completing the winding of the plastic pipe. The device realizes the function of winding the plastic pipe, eliminating the need for the staff to wind the plastic pipe later, saving time and effort, and indirectly improving the processing efficiency of the staff for the plastic pipe. The winding roller 8 is movably inserted into the outer side surface of the first support plate 5. The output end of the driving motor 7 is fixedly connected to the rear end of the winding roller 8. A second support plate 9 is movably sleeved on the front side of the outer surface of the winding roller 8. A connecting block 10 is fixedly connected to the lower surface of the second support plate 9. The connecting block 10 is slidably connected to the connection groove 3. A through groove 11 is opened on the front surface of the connecting block 10. A limiting rod 12 is movably inserted into the outer side surface of the connecting block 10. The limiting rod 12 is movably inserted into the limiting hole 4. The inner end of the limiting rod 12 is fixedly connected to a moving block 13. The moving block 13 is slidably connected to the connecting block 10. A hand grip 14 is fixedly connected to the front surface of the moving block 13. The hand grip 14 is slidably connected to the through groove 11. A short rod 15 is fixedly connected to the inner side surface of the moving block 13. A return spring 16 is sleeved on the outer surface of the short rod 15. Due to the reaction force generated by the compression of the return spring 16, the moving block 13 can be continuously extruded outward, enabling the moving block 13 to drive the limiting rod 12 to move outward along the inside of the connecting block 10 until the limiting rod 12 passes through the outer side surface of the connecting block 10 and finally firmly inserts into the limiting hole 4, effectively improving the fixing effect between the connecting block 10 and the connection groove 3, and indirectly ensuring the stability of the second support plate 9 during use.

[0024] In order to improve the connection stability between the fixed plate 6 and the first support plate 5, a triangular plate 17 is fixedly connected to the lower surface of the fixed plate 6. The front surface of the triangular plate 17 is fixedly connected to the back surface of the first support plate 5. The triangular plate 17 increases the connection area between the fixed plate 6 and the first support plate 5, and improves the connection stability between the fixed plate 6 and the first support plate 5.

[0025] In order to facilitate the movement of the moving block 13 along the inside of the connecting block 10, a moving groove is provided inside the connecting block 10. The inner diameter of the moving groove is adapted to the outer diameter of the moving block 13, which facilitates the movement of the moving block 13 along the inside of the connecting block 10.

[0026] In order to extend the service life of a set of return springs 16, the number of return springs 16 is set to one set. The production material of the set of return springs 16 is set to silicon manganese spring steel. The spring made of silicon manganese spring steel has a good return effect and is not easy to deform, thus extending the service life of the set of return springs 16.

[0027] In order to improve the connection stability between the first support plate 5 and the traction machine body 1, a connecting frame 18 is fixedly sleeved at the bottom of the outer side of the first support plate 5. The lower surface of the connecting frame 18 is fixedly connected to the upper surface of the traction machine body 1. The connecting frame 18 increases the connection area between the first support plate 5 and the traction machine body 1, and improves the connection stability between the first support plate 5 and the traction machine body 1.

[0028] In order to ensure that the connecting block 10, the limiting rod 12, the moving block 13, the hand buckle 14 and the short rod 15 are not easily damaged during use, the production materials of the connecting block 10, the limiting rod 12, the moving block 13, the hand buckle 14 and the short rod 15 are set to stainless steel. Stainless steel has a higher hardness and is not easy to deform, ensuring that the connecting block 10, the limiting rod 12, the moving block 13, the hand buckle 14 and the short rod 15 are not easily damaged during use.

[0029] The electrical components appearing in this article are all electrically connected to an external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.

[0030] During use, due to the rotatability of the moving wheels 2, the staff can move the device to the designated working position. Subsequently, the staff starts the traction machine body 1, causing the traction machine body 1 to start pulling the extruded plastic pipe. At the same time, the staff winds one end of the pulled plastic pipe around the outer surface of the winding roller 8. Meanwhile, the driving motor 7 is started, and the output end of the driving motor 7 drives the winding roller 8 to rotate along the inside of the first support plate 5 and the second support plate 9, causing the winding roller 8 to start winding the plastic pipe until the winding of the plastic pipe is completed. Subsequently, the driving motor 7 is immediately turned off, causing the winding roller 8 to stop rotating. Then, the staff controls the hand buckle 14 to drive the moving block 13 and the limiting rod 12 to move inward along the inside of the through groove 11 and the inside of the connecting block 10, causing the moving block 13 to drive the short rod 15 to squeeze the reset spring 16 inward until the limiting rod 12 is moved out of the inside of the limiting hole 4. Thus, the fixation between the connecting block 10 and the connecting groove 3 is released. Subsequently, the staff controls the connecting block 10 to drive the second support plate 9 to move forward until the second support plate 9 is separated from the outer surface of the winding roller 8, removing the occlusion of the outer surface of the winding roller 8. Then, the staff pulls out the coiled plastic pipe on the outer surface of the winding roller 8 forward until it is separated from the outer surface of the winding roller 8. Thus, the winding of the plastic pipe is completed.

[0031] In summary, for the traction device for plastic pipe extrusion molding, the driving motor 7 can drive the winding roller 8 to wind the plastic pipe pulled out by the traction machine body 1. After the winding is completed, the limiting rod 12 is controlled to move out of the inside of the limiting hole 4, indirectly causing the second support plate 9 to remove the occlusion of the outer surface of the winding roller 8. Then, the staff can remove the coiled plastic pipe on the surface of the winding roller 8. Thus, the winding of the plastic pipe is completed. This device realizes the function of winding the plastic pipe, eliminating the need for the staff to wind the plastic pipe later, saving time and effort, and indirectly improving the processing efficiency of the staff for the plastic pipe.

[0032] For the traction device for plastic pipe extrusion molding, due to the reaction force generated by the extrusion of the reset spring 16, it can continuously squeeze the moving block 13 outward, causing the moving block 13 to drive the limiting rod 12 to move outward along the inside of the connecting block 10 until the limiting rod 12 passes through the outer side of the connecting block 10 and finally firmly inserts into the inside of the limiting hole 4, effectively improving the fixation effect between the connecting block 10 and the connecting groove 3 and indirectly ensuring the stability of the second support plate 9 during use.

[0033] The traction device for plastic pipe extrusion molding realizes the movable function through the rotatability of four groups of moving wheels 2, which facilitates the staff to move the device to any working position according to the working requirements, saving time and effort, improving the convenience of the device during use, and facilitating the staff to use the device.
