A moving groove is opened on one side of each moving column 5, a curling prevention structure 6 is provided on each moving column 5, and two quick-disassembly components 7 are provided on one side of each moving column 5.

[0031] For the purpose of achieving winding, two fixed columns 10 are fixedly connected to the upper surface of the base 1. Rotating columns are rotatably connected to the opposite sides of the two fixed columns 10, and a winding disc 11 is fixedly connected to the two rotating columns together. A third servo motor 12 is fixedly connected to one side of one of the fixed columns 10, and the output shaft of the third servo motor 12 is fixedly connected to one end of one of the rotating columns. The third servo motor 12 drives the winding disc 11 to rotate through the rotating column, facilitating the winding of the polyurethane waterproof coiled material.

[0032] For the purpose of achieving the reduction of the curling probability, the curling prevention structure 6 includes a second bidirectional threaded rod 602 rotatably connected in the moving groove. A second servo motor 601 is fixedly connected to the upper surface of the moving column 5, and the output shaft of the second servo motor 601 is fixedly connected to one end of the second bidirectional threaded rod 602. Second sliding blocks 603 are threadedly connected to the opposite threads of the second bidirectional threaded rod 602, and each second sliding block 603 is slidably connected in the moving groove. A connecting frame 604 is fixedly connected to one side of each second sliding block 603, and a connecting block 605 is slidably connected inside each connecting frame 604.

[0033] A fixing hole is formed on one side of each connecting block 605, and a flattening column 606 is fixedly connected to one side of each connecting block 605.

[0035] Working principle: One end of the polyurethane waterproof coiled material passes through the two groups of connecting columns 8, so that the two rotating rollers 9 are clamped on the polyurethane waterproof coiled material, and then wound on the winding disc 11. The third servo motor 12 drives the winding disc 11 to rotate through the rotating column to wind the polyurethane waterproof coiled material. At the same time, the first servo motor 3 drives the first bidirectional threaded rod 2 to rotate, and the first bidirectional threaded rod 2 drives the first sliding block 4 to move, and the first sliding block 4 drives the corresponding moving column 5 to move.

[0036] According to the width of the polyurethane waterproof coil, move the two moving columns 5 to appropriate positions, and then the second servo motor 601 drives the second bidirectional threaded rod 602 to rotate. The second bidirectional threaded rod 602 drives the connection frame 604 to move through the second sliding block 603. The connection frame 604 drives the flattening column 606 to move through the connection block 605, so that the flattening columns 606 on both sides of the polyurethane waterproof coil drive the fine brushes to fit on the upper and lower surfaces of the polyurethane waterproof coil. When the polyurethane waterproof coil moves, the fine brushes brush on both sides of the polyurethane waterproof coil to flatten both sides of the polyurethane waterproof coil, which is beneficial to reducing the probability of the polyurethane waterproof coil curling and improving the winding quality of the winding disc 11 for winding the polyurethane waterproof coil. Pull the sliding rod 702, and the sliding rod 702 drives the clamping column 703 to move, so that the clamping column 703 disengages from the fixing hole, and then take out the connection block 605, which is convenient for the staff to quickly replace the fine brush on the flattening column 606.
