[0019] The elastic pressing structure of the winding machine described in this utility model uses a fixing component 3 and a starting component 4 to mount the winding roller 2 on the bracket 1. Then, the starting component 4 drives the winding roller 2, which, with the cooperation of the fixing component 3, can rotate and wind up the material. At the same time, the telescopic component 5 drives the U-shaped frame 7, so that the pressure roller 8 can press the wound material. While pressing, with the cooperation of the elastic component 6, the pressure roller 8 can move as the winding roller 2 winds up and thickens without affecting the pressing effect. Then, under the action of the U-shaped scraper 9, the pressure roller 8, which rotates with the winding roller 2, can be scraped to remove dirt, glue particles, dust, etc., adhering to the pressure roller 8, thereby keeping the surface of the pressure roller 8 smooth, ensuring uniform pressure, and preventing impurities from damaging the roll material. At the same time, with the cooperation of the dust suction component 10, the scraped impurities can be sucked away immediately to prevent secondary pollution.
[0020] Furthermore, the telescopic assembly 5 includes a fixed frame 51 fixedly installed on the inner top wall of the bracket 1. Two cylinders 52 are symmetrically fixedly installed on one side of the fixed frame 51, and a connecting plate 53 is fixedly installed at the output end of the two cylinders 52. The connecting plate 53 is driven by the cylinders 52 extending from the fixed frame 51, so that the connecting plate 53 can drive the U-shaped frame 7 to move with the cooperation of the elastic component 6, thereby enabling the pressure roller 8 to press the wound material on the take-up roller 2.
[0021] Furthermore, the elastic component 6 includes a T-shaped rod 61 that passes through the connecting plate 53, and a U-shaped frame 7 is fixedly installed at the bottom end of the T-shaped rod 61. A first spring 62 is provided on the outer wall of the T-shaped rod 61, and the first spring 62 is located between the connecting plate 53 and the U-shaped frame 7. Through the T-shaped rod 61 and with the cooperation of the first spring 62, the pressure roller 8 can move as the winding roller 2 winds up and thickens, without affecting the pressing effect.
[0022] Furthermore, the dust collection assembly 10 includes a blowpipe 101 disposed on one side of the U-shaped scraper 9, and both ends of the blowpipe 101 are fixedly connected to the direction plate on the U-shaped scraper 9, and the branch pipe on the blowpipe 101 extends to the inner side of the U-shaped scraper 9; an L-shaped pipe 102 is fixedly installed on the outer wall of the blowpipe 101, and a filter purification box 103 and an air pump 104 are fixedly installed on the mounting bracket 51 respectively, and the input end of the air pump 104 is connected to the filter purification box 103 through a connecting pipe, and a flexible hose 105 is fixedly installed at the bottom of the filter purification box 103, and the other end of the flexible hose 105 passes through one side wall of the mounting bracket 51 and is connected to the L-shaped pipe 102.

[0023] Furthermore, the starting assembly 4 includes a T-shaped column 41 rotatably mounted on the bracket 1, with a cross plate at one end of the take-up roller 2 interlocking with a cross groove at one end of the T-shaped column 41. A timing pulley 42 is fixedly mounted on the other end of the T-shaped column 41. A motor 43 is fixedly mounted on the bracket 1, and a timing pulley 42 is fixedly mounted on the output end of the motor 43. The timing pulley 43 and the timing pulley 42 are connected by a timing belt tensioning engagement. The motor 43 drives the timing pulley 42, which in turn drives the timing pulley 42 under the action of the timing belt, thus enabling the T-shaped column 41 to rotate. The rotating T-shaped column 41 then drives the take-up roller 2 to rotate and take up the item via the interlocking cross plate.
[0024] Furthermore, the fixing assembly 3 includes a rotating cylinder 31 that is rotatably mounted on the bracket 1. A mounting frame 32 is fixedly mounted on the disc of the rotating cylinder 31.

A second spring 35 is provided on the outside of the cross bar 33 and is located in the middle between the mounting frame 32 and the disc on the cross bar 33. By manually pulling the handle on one side of the cross bar 33, the cross bar 33 inserted on the mounting frame 32 can be driven to retract the cross insert 34, which extends out and is inserted into the cross plate, into the rotating cylinder 31. Then, the take-up roller 2 is manually or mechanically held and moved to one side of the rotating cylinder 31, so that the cross plate at the other end of the take-up roller 2 can be pulled out from the T-shaped post 41, thereby allowing the take-up roller 2 to be disassembled.

A rectangular opening 15 is provided at the corner of the U-shaped scraper 9, and the rectangular opening 15 is located above the collection box 11.
[0026] The rewinder elastic pressing structure described in this embodiment uses a fixing mechanism to fix the collection box 11 below the U-shaped scraper 9. Then, while the U-shaped scraper 9 scrapes the pressure roller 8, the scraped impurities can fall into the collection box 11 from the rectangular opening 15 for collection, thereby improving the collection and cleaning effect of impurities.
[0027] Furthermore, the fixing mechanism includes a Y-shaped plate 12 fixedly mounted on the U-shaped scraper 9. A hand-tightening screw 13 is threaded onto the Y-shaped plate 12, and a clamping frame 14 is rotatably mounted on the screw end of the hand-tightening screw 13. The clamping frame 14 is inserted into the strip grooves on both sides of the collection box 11. By manually turning the hand-tightening screw 13 threaded onto the Y-shaped plate 12, the hand-tightening screw 13 drives the clamping frame 14 on one side to insert into the strip groove on the collection box 11, thereby clamping the collection box 11 and thus stably fixing the collection box 11 below the U-shaped scraper 9.
