[0002] PE pipe coiling machine, this equipment is specially designed for processing polyethylene (PE) pipes. Its core functions include the winding, packaging and winding of PE pipes. It is widely used in the production and processing of plastic pipes. It should be noted that there are many types of PE pipe coiling machines on the market, and each device has its own unique functions and characteristics. Therefore, when purchasing and using it, users must carefully select and consider according to their own needs and actual conditions.

[0003] It is worth mentioning that the structural design of some coil machines is relatively complex, especially in the removal and installation of the coil tube. This feature requires operators to have professional knowledge and be familiar with specific operating steps to ensure smooth operation. This undoubtedly increases the difficulty of operation and also increases the cost of replacement. For some coil machines, due to the large size or heavy weight of the coil tube, professional tools and equipment are often required during the removal and replacement process. This undoubtedly further increases the complexity of the operation and the time cost required.

[0004] In the coiling process of PE pipe, tension control is crucial. Too much tension may cause deformation or even damage to the pipe, while too little tension may cause the pipe to loosen, thus affecting the overall effect of the coiling. Therefore, to ensure the quality and safety of the pipe, the tension must be precisely controlled. However, some coiling machines on the current market may have certain deficiencies in tension adjustment, such as the adjustment method is not intuitive enough and the adjustment range is limited. These problems may have an adverse effect on the coiling effect and pipe quality. Utility Model Content

A side block 5 is provided on the inner side of the other end of the bracket 1, and the upper end of each side block 5 is connected to a mounting frame 6. A bearing device 9 is installed on the mounting frame 6, and a second coil tube 8 is installed at the bearing device 9 through a mounting roller 7.

[0026] The mounting frame 6 and the side block 5 are both provided with aligned waist holes 10, into which the first fastener 11 and the second fastener 12 are inserted, so that the mounting frame 6 can be fixed on the side block 5. When the second coil tube 8 needs to be disassembled and replaced, only the first fastener 11 and the second fastener 12 need to be removed.

[0027] Each second fastener 12 is also provided with an oblique strip 13, and an arc-shaped slide groove 14 is provided on the end surface of the oblique strip 13. Adjustment rods 15 are installed at two opposite arc-shaped slide grooves 14, and a tensioning roller 16 is installed on the rod body of the adjustment rod 15. The PE pipe passes through the tensioning roller 16 from the first coil tube 3 and the second coil tube 8, and the tension of the PE pipe can be adjusted by adjusting the tensioning roller 16.

[0028] The bracket 1 and the side block 5 are designed as one piece, and the two brackets 1 are designed in parallel. The connecting frame 4 is fixed to the bracket 1 by bolts. The cross section of the mounting frame 6 is designed in an "L" shape, and is also fixed to the bearing device 9 by bolts. The mounting roller 7 passes through the bearing device 9 and is limited by a nut, and the second coil tube 8 is limited on the mounting roller 7 by a nut.

[0029] The first fastener 11 and the second fastener 12 are both composed of a screw, a nut and a gasket, and nuts and gaskets are sleeved on both ends of the screw, and the screw is fixed to the waist hole 10 by nuts and gaskets. The screw of the second fastener 12 and the oblique bar 13 are designed as one piece.

[0030] The tilt range of the oblique bar 13 is between 30 and 75 degrees, and a rubber pad is bonded to its surface. The adjustment rod 15 is fixed to the oblique bar 13 by a nut and a gasket. The tensioning roller 16 is restricted on the adjustment rod 15 by a nut, and can be rotatably set on the adjustment rod 15. The groove wall of the tensioning roller 16 is designed in an arc shape, and its groove wall is smooth to ensure that the PE pipe can pass smoothly.

[0031] Disassembly and assembly process: First, turn off the power of the coiler to ensure that the equipment is in a safe and static state; use appropriate tools, such as a wrench or a screwdriver, to remove the first fastener 11 and the second fastener 12 respectively; after removing the fasteners, the mounting frame 6 can be removed from the side block 5; then, by releasing the nut limit on the mounting roller 7, the second coil tube 8 can be removed from the mounting roller 7; at the same time, remove the tensioning roller 16 from the adjusting rod 15, and move the adjusting rod 15 out of the arc-shaped slide groove 14 of the oblique bar 13;

[0032] Place the new second coil tube 8 on the installation roller 7 and re-secure it with a nut; re-install the mounting frame 6 onto the side block 5, ensuring that the waist hole 10 is aligned; re-secure the mounting frame 6 and the side block 5 using the first fastener 11 and the second fastener 12; reinsert the adjustment rod 15 into the arc-shaped slide groove 14 of the diagonal bar 13, and secure the tensioning roller 16 at the required position; adjust the position of the tensioning roller 16 to achieve proper adjustment of the PE pipe tension;

[0033] When the coil machine starts working, the driving device 2 drives the first coil tube 3 to rotate, and the PE pipe passes through the first coil tube 3 and then through the second coil tube 8, and then passes through the tensioning roller 16; according to the tensioning requirement of the PE pipe, the distance between the tensioning roller 16 and the second coil tube 8 can be changed by adjusting the position of the rod 15 on the oblique bar 13, so as to adjust the tension of the PE pipe; the arc-shaped groove wall design of the tensioning roller 16 can ensure that the PE pipe is subjected to uniform pressure when passing through, so as to maintain the smooth transportation of the PE pipe; during the entire working process, the tensioning structure ensures that the PE pipe maintains appropriate tension to prevent excessive relaxation or excessive tension, so as to ensure the coil quality and work efficiency.
