[0003] Problems with existing technology:
[0004] When using existing PE pipe coiling machines, one end of the PE pipe is usually fixed to the coiling wheel, then the coiling wheel is rotated to roll the PE pipe up, and then the coiled PE pipe is tied with cable ties. The tied PE pipe is then removed from the coiling wheel. However, existing coiling wheels usually use tape to fix the end of the PE pipe, which is cumbersome to operate and difficult to remove due to the tape, and there will also be tape residue. Utility Model Content
[0005] The purpose of this utility model is to provide a PE pipe coiling machine. The design of the drive plate enables the sliding block and other components to move according to the shape of the rectangular toothed groove. During this process, the end of the pipe to be coiled, which is sleeved on the outside of the sliding adapting pin, can be fixed by the sliding adapting pin approaching the receiving groove. Subsequently, when the pipe to be coiled is pressed and fixed by the second layer itself, the sliding adapting pin separates from the end of the pipe to be coiled according to the rectangular toothed groove. At the same time, the design of two sliding adapting pins can meet the clamping of pipes of different diameters.
[0006] The specific technical solution adopted by this utility model is as follows:

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1-3 As shown, a PE pipe coiling machine includes: a pipe feeder 1, a coiling rotating machine 2 is provided on one side of the pipe feeder 1, the output end of the pipe feeder 1 extends out to form a pipe 5 to be coiled, a coiling wheel 3 is rotatably provided on one side of the coiling rotating machine 2, the pipe 5 to be coiled is wound around the outside of the coiling wheel 3, and a fixing component 4 is provided on the coiling wheel 3 at the position corresponding to the end of the pipe 5 to be coiled; the fixing component 4 includes a sliding block 401, a receiving groove is provided on the coiling wheel 3 at the position corresponding to the fixing component 4, the sliding block 401 is movably arranged with the receiving groove, a sliding groove box 404 is provided on the side of the sliding block 401 near the receiving groove, a drive plate 406 is provided on one side of the sliding groove box 404, and a sliding adaptation pin 409 is provided at the end of the sliding block 401.
[0026] When PE pipes need to be coiled, a section of pipe to be coiled 5 is first fed out by the pipe feeder 1. Then, the end of the pipe to be coiled 5 is fitted onto one end of the sliding adaptation pin 409. The design of the drive plate 406 makes the sliding adaptation pin 409 clamp the end of the pipe to be coiled 5. When the pipe to be coiled 5 outside the coiling wheel 3 is coiled to the second layer, the sliding adaptation pin 409 releases the clamping of the pipe to be coiled 5 under the action of the drive plate 406. The coiling machine 2 is equipped with a motor and a reciprocating shaft. The motor is used to drive the coiling wheel 3 to rotate, and the reciprocating shaft is used to make the coiling wheel 3 move laterally back and forth to make the PE pipes more evenly arranged when coiling. The pipe feeder 1 is used to feed the PE pipes to the coiling wheel 3.
[0027] See attached document Figures 3-4 The drive plate 406 has a rectangular toothed groove 415 on its surface. A transmission rod 407 is rotatably mounted in the storage slot corresponding to the position of the rectangular toothed groove 415. The end of the transmission rod 407 extends into the interior of the rectangular toothed groove 415 and is fixedly connected to a guide gear 4071. The guide gear 4071 meshes with the rectangular toothed groove 415. A clamping motor 405 is fixedly connected to one side of the storage slot corresponding to the middle position of the transmission rod 407. A bevel gear is fixedly connected to both the output end of the clamping motor 405 and the middle position of the transmission rod 407. The two bevel gears mesh with each other.
[0028] According to the above structure, the rectangular toothed groove 415 is designed to resemble a rectangle. The clamping motor 405 starts the transmission rod 407 to rotate, thereby causing the drive plate 406 to move according to the shape of the rectangular toothed groove 415 of the actuating wheel. The drive plate 406 then drives the movement of components such as the sliding block 401. When the transmission rod 407 drives the drive plate 406 to move away from the receiving groove through the meshing connection between the guide rail gear 4071 and the rectangular toothed groove 415 of the actuating wheel, the sliding block 401 moves away from the receiving groove. When the sliding block 401 moves upward, the coil 5 can be sleeved on the outside of the sliding adaptation pin 409. Then the sliding block 401 approaches the receiving groove to clamp the end of the coil 5. At this time, the coil wheel 3 rotates under the drive of the coil rotating machine 2. When the coil 5 is wound to the second layer on the outside of the coil wheel 3, the sliding adaptation pin 409 moves downward to release the clamping of the coil 5. This process is repeated until the subsequent winding is finished, at which point the coil 5 can be removed.
[0029] See attached document Figure 5There are two sliding adaptation pins 409. The ends of the two sliding adaptation pins 409 are slidably installed with the sliding block 401. The two sliding adaptation pins 409 are symmetrically arranged. A middle plate 408 is fixedly connected to the middle position of the sliding block 401 corresponding to the two sliding adaptation pins 409. A bidirectional screw 410 is rotatably installed at the end of the middle plate 408. A blocking post 403 is rotatably installed at the position of the two sliding adaptation pins 409 corresponding to the position of the bidirectional screw 410. The two ends of the bidirectional screw 410 are threadedly connected to the two blocking posts 403. A turntable 414 is fixedly connected to the middle position of the bidirectional screw 410. The thread directions of the two ends of the bidirectional screw 410 are opposite.
[0030] According to the above structure, based on the sliding characteristic of the sliding adaptation pin 409, when the two sliding adaptation pins 409 are close to each other, a larger diameter PE pipe can be fitted, and vice versa. By turning the turn wheel 414, the bidirectional screw 410 is rotated. Since the thread directions at both ends of the bidirectional screw 410 are opposite, the blocking posts 403 threaded to both ends move away or closer synchronously when the bidirectional screw 410 rotates, so that the blocking posts 403 move with it. The blocking posts 403 are used to prevent the coil 5 from being fitted too much.
[0031] See attached document Figure 6 The sliding block 401 has a groove corresponding to the position of the sliding box 404. The sliding box 404 and the sliding groove are slidably installed. An internal spring 413 is fixedly connected between the sliding box 404 and the sliding groove. A buffer cap 402 is provided on the side of the sliding adaptation pin 409 near the coil wheel 3. A buffer groove is provided on the position of the sliding adaptation pin 409 corresponding to the buffer cap 402. The buffer cap 402 and the buffer groove are slidably installed. A contact spring 412 is fixedly connected between the buffer cap 402 and the buffer groove.
[0032] According to the above structure, the built-in spring 413 and the contact spring 412 are both used for buffering during clamping, increasing the service life of the device.
[0033] The working principle of this utility model is as follows: When it is necessary to coil the PE pipe, a section of pipe to be coiled 5 is first fed out by the pipe feeder 1, and then the end of the pipe to be coiled 5 is sleeved on one end of the sliding adaptation pin 409. The design of the drive plate 406 makes the sliding adaptation pin 409 clamp the end of the pipe to be coiled 5. When the pipe to be coiled 5 outside the coiling wheel 3 is wound to the second layer, the sliding adaptation pin 409 releases the clamping of the pipe to be coiled 5 under the action of the drive plate 406.
[0034] The rectangular toothed groove 415 has a rectangular design. The clamping motor 405 starts the transmission rod 407 to rotate, thereby causing the drive plate 406 to move according to the shape of the rectangular toothed groove 415. The drive plate 406 then drives the sliding block 401 and other components to move. When the transmission rod 407 is connected to the rectangular toothed groove 415 through the meshing of the guide gear 4071, the drive plate 406 moves away from the receiving groove, and the sliding block 401 moves away from the receiving groove. When the sliding block 401 moves upward, the coil 5 can be sleeved on the outside of the sliding adaptation pin 409. Then the sliding block 401 approaches the receiving groove to clamp the end of the coil 5. At this time, the coil wheel 3 rotates under the drive of the coil rotating machine 2. When the coil 5 is wound to the second layer on the outside of the coil wheel 3, the sliding adaptation pin 409 moves downward to release the clamp from the coil 5. This process is repeated until the coiling is finished.
[0035] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
