[0003] For example, the Chinese utility model with application number 201220287436.X proposes a tape rewinding machine. The patent first allows the control device to control the rotation of the motor to perform the rewinding work. At the same time, the rotation of the shaft drives the counting and measuring device to start counting, and displays it through the counting display device. When a certain number is reached, the control device controls the motor to stop working. However, bubbles will be generated in the process of rewinding the tape. The patent cannot adjust the tension of the tape when rewinding the tape. The tape is prone to wrinkles when rewinding, resulting in the tape on the rewinding wheel not being closely attached and being relatively loose, affecting the subsequent rewinding quality, and the tape rewinding wheel is also prone to idling.

[0004] Therefore, the utility model provides a winding device of an adhesive tape rewinding machine. Utility Model Content

[0023] The following will be combined with the attached embodiment of the present utility model Figure 1-Figure 5 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0024] See also Figure 1-5In the embodiment of the utility model, a winding device of a tape rewinding machine includes a workbench 1, a left supporting plate 2 is installed on the left side of the top of the workbench 1, the top of the left supporting plate 2 is connected to the right winding shaft 3, a plurality of expansion members 4 are embedded and installed on the surface of the winding shaft 3, a second screw rod 19 is connected inside the winding shaft 3, a rotating knob 5 is connected to the front end of the second screw rod 19, an adjusting plate 20 is sleeved on the surface of the second screw rod 19, a third connecting block 21 is connected to the rear end of the adjusting plate 20, a second connecting shaft 18 is connected to the surface of the third connecting block 21, an expansion member 4 is connected to the top of the second connecting shaft 18, a motor 6 is connected to the rear end of the left supporting plate 2, and .... The second fixed block 12 is connected to the first connecting block 13, the top of the first connecting block 13 is connected to the first connecting shaft 14, the top of the first connecting shaft 14 is connected to the adjusting block 15, the adjusting block 15 is connected to the first screw rod 16, the top of the first screw rod 16 is connected to the second connecting block 17, the top of the workbench 1 is connected to two first fixed blocks 8, the first fixed block 8 is connected to the connecting rod 9, the top of the connecting rod 9 is connected to the adjusting roller 10, the middle of the connecting rod 9 is connected to the adjusting rod 11, the right support plate 7 is installed on the right side of the top of the workbench 1, the right support plate 7 is connected to the conveying roller 22, first put the tape on the conveying roller 2 2 surface, and then passes between the adjusting roller 10 and the adjusting rod 11, and then the motor 6 is started to put the adhesive tape on the surface of the take-up shaft 3 for winding. When the tension of the adhesive tape needs to be adjusted, the adjusting block 15 is rotated to make the first screw rod 16 move downward along the inner wall of the adjusting block 15, thereby driving the second connecting block 17 to move downward with the first screw rod 16. Since the adjusting rod 11 passes through the second connecting block 17, the adjusting rod 11 moves downward with the second connecting block 17, thereby driving the connecting rod 9 to move downward, so that the adjusting roller 10 contacts with the surface of the adhesive tape, pressing the adhesive tape, thereby adjusting the tension of the adhesive tape. When the adhesive tape is wound, bubbles are generated and the adhesive tape is wound. When the surface adhesion of the reel is low, turn off the motor 6 to stop reeling, then turn the rotary knob 5 to drive the second screw rod 19 to rotate, and the second screw rod 19 drives the adjustment plate 20 to move forward and backward along the second screw rod 19, thereby driving the second connecting shaft 18 to move. When the angle between the second connecting shaft 18 and the inner wall of the expansion member 4 gradually becomes vertical, the expansion member 4 will gradually move toward the outside of the reel 3 due to the support of the second connecting shaft 18. When the surface of the reel 3 is wound with tape, the expansion member 4 can support the inside of the tape and compress the tape to prevent the tape from having a low adhesion to the surface of the reel due to bubbles during the reeling process, thereby ensuring the reeling quality.

[0025] In the embodiment of the utility model, the output shaft of the motor 6 is fixedly connected to the winding shaft 3, the rotating knob 5 passes through the left support plate 2 and is fixedly connected to the second screw rod 19, and is rotatably connected to the left support plate 2.

The cylinder passes through and is connected to the second connecting shaft 18, and the second connecting shaft 18 is rotatably connected to the expansion member 4. The expansion member 4 can be moved by setting the second connecting shaft 18 and the adjustment plate 20.

[0026] When in use, first turn the rotating knob 5 to drive the second screw rod 19 to rotate, and the second screw rod 19 drives the adjustment plate 20 to move forward and backward along the second screw rod 19, thereby driving the second connecting shaft 18 to move. When the angle between the second connecting shaft 18 and the inner wall of the expansion member 4 gradually becomes vertical, the expansion member 4 will gradually move toward the outside of the winding shaft 3 due to the support of the second connecting shaft 18. When the tape is wound on the surface of the winding shaft 3, the expansion member 4 can support the inside of the tape and compress the tape to prevent the tape from having a low fit with the surface of the winding wheel due to bubbles during the winding process, thereby ensuring the winding quality.

[0028] When in use, first rotate the adjusting block 15 to make the first screw rod 16 move up and down along the inner wall of the adjusting block 15, thereby driving the second connecting block 17 to move up and down following the first screw rod 16. Since the adjusting rod 11 passes through the second connecting block 17, the adjusting rod 11 moves up and down following the second connecting block 17, thereby driving the connecting rod 9 to move left and right. When the second connecting block 17 moves upward, the connecting rod 9 moves to the right, and when the second connecting block 17 moves downward, the connecting rod 9 moves to the left.

[0029] The adjusting rod 11 passes through the second connecting block 17 and is rotatably connected to the connecting rod 9. The adjusting roller 10 is rotatably connected to the connecting rod 9. The adjusting roller 10 can be provided to adjust the tension of the tape when the tape is rolled up.

[0030] When in use, the tape is passed between the adjusting roller 10 and the adjusting rod 11, and then the tape is placed on the surface of the winding shaft 3 for winding. When the tension of the tape needs to be adjusted, the adjusting roller 10 is moved downward to contact the surface of the tape so that the adjusting roller 10 can press the tape, thereby adjusting the tension of the tape. Because the adjusting roller 10 is rotatably connected to the connecting rod 9, the adjusting roller 10 will be in a rotating state when the tape is moving, so it will not affect the efficiency of tape winding and the quality of the tape.
