The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-4 This utility model provides a winding device for processing PVC edge banding strips, including a base 1, a winding frame 102 on the top of the base 1, four equally spaced fixing plates 3 on one side of the winding frame 102, and a winding reel 4 between every two fixing plates 3. Multiple arc-shaped support plates 401 are equally spaced and arranged in a ring on the outside of each winding reel 4. Each arc-shaped support plate 401 has a deformation cavity inside. A fixing piece 402 is fixedly connected to the outside of one of the arc-shaped support plates 401. A guide roller 2 is provided on the top of the winding frame 102, and an installation part 101 is provided on the bottom of the base 1.

[0024] The base 1 is installed on the winding end of the PVC edge banding processing equipment via the mounting part 101 at the bottom. One end of the processed PVC edge banding is conveyed to the outside of the winding reel 4, which is furthest from the motor, via the guide roller 2. The PVC edge banding roll is placed on the arc-shaped support plate 401 of the target winding reel 4. The starting end of the edge banding is fixed by the fixing plate 402. The deformation cavity of the arc-shaped support plate 401 provides elastic support, adapts to different roll diameters, and ensures clamping force. The winding reel 4 is pushed so that the cross protrusions of the sliding docking plates 404 on both sides are inserted into the cross grooves 302 of the inner plate 301 of the fixing plate 3. The spring 405 presses the sliding docking plates 404 to ensure that the cross protrusions and the cross grooves 302 are tightly engaged, realizing power transmission and starting the winding motor 5 to realize the winding of the PVC edge banding.

[0025] In this embodiment, an inner disk 301 is rotatably connected inside each fixed plate 3. A cross groove 302 is provided inside the inner disk 301. A docking sleeve 403 is provided at the center of both sides of the take-up reel 4. A sliding docking plate 404 is slidably connected inside each docking sleeve 403. A spring 405 is provided on the side of the sliding docking plate 404 facing the take-up reel 4. A cross protrusion adapted to the cross groove 302 is provided on the side of the sliding docking plate 404 facing the inner disk 301. The cross protrusion penetrates and extends to the outside of the docking sleeve 403. An extension actuating block 406 is fixedly connected to one side of the sliding docking plate 404. The extension actuating block 406 extends to the outside of the docking sleeve 403. A take-up motor 5 is fixedly connected to one side of one fixed plate 3. The output shaft of the take-up motor 5 is fixedly connected to the inner disk 301 inside the fixed plate 3.

[0026] Once the current roll is fully wound, the outer extension actuation block 406 causes the cross protrusion of the sliding docking plate 404 to disengage from the cross groove 302 of the inner disc 301. The sealing strip moves laterally, aligning the cross protrusion of the adjacent winding disc 4 with the cross groove 302 of the next set of inner discs 301. The extension actuation block 406 is then released to complete the automatic docking, thereby enabling winding without gaps and greatly improving work efficiency.

[0027] The four-station take-up reel 4 is designed to support alternating operations. When switching, simply move the extended toggle block 406 and move the take-up frame 102 laterally without stopping the machine, thus improving production efficiency. It flexibly adapts to different roll sizes, avoiding deformation or slippage caused by traditional clamps. The rigid transmission prevents slippage, and the docking / separation operation only requires one hand to move, saving time and effort. The mechanical structure enables quick roll changing without the need for complex sensors or control systems, making maintenance simple and cost-effective. The mounting part 101 facilitates equipment fixation and is compatible with existing production lines.

[0028] It should be noted in the above scheme that when winding up the PVC edge banding strip, it is necessary to start winding from the winding reel 4, which is furthest from the winding motor 5.

[0029] The working principle and usage process of this utility model are as follows: First, one end of the processed PVC edge banding strip is conveyed to the outside of the take-up reel 4, which is furthest from the motor, via the guide roller 2. The roll of the PVC edge banding strip is then placed on the arc-shaped support plate 401 of the target take-up reel 4. The starting end of the edge banding strip is fixed by the fixing plate 402. The deformation cavity of the arc-shaped support plate 401 provides elastic support, adapts to different roll diameters, and ensures clamping force. The take-up reel 4 is pushed so that the cross protrusions of the sliding docking plates 404 on both sides are inserted into the cross grooves 302 of the inner plate 301 of the fixing plate 3. The spring 4... 05. Press the sliding docking plate 404 to ensure that the cross protrusion and the cross groove 302 are tightly engaged, so that the power transmission can start the winding motor 5 to wind up the PVC edge banding strip. After the current roll is full, the outer extension actuating block 406 is pushed to make the cross protrusion of the sliding docking plate 404 disengage from the cross groove 302 of the inner plate 301. The edge banding strip is moved laterally to align the cross protrusion of the adjacent winding reel 4 with the cross groove 302 of the next set of inner plates 301. Release the extension actuating block 406 to complete the automatic docking, thereby achieving winding without gaps and greatly improving work efficiency.
