Description

Technical Field

[0001] The utility model relates to the technical field of tape winding and unwinding, in particular to a tape slitting, winding and unwinding device. Background Technique

[0002] A tape is composed of a base material and an adhesive, and two or more non-connected objects are connected together through bonding. When the tape is produced, it is initially produced in a large roll shape, and then slit and wound into small rolls. During this process, the tape will go through multiple winding and unwinding operations.

[0003] Currently, when the tape is wound and unwound, the large roll of tape is mainly slit and directly wound onto the small roll through multiple sets of tension rollers. However, during the winding process, due to the gradually increasing size of the rolled tape and the influence of the tape tension during slitting, the surface of the tape is not flat during winding, and bubbles, wrinkles, etc. are likely to occur on the surface during winding, affecting the subsequent winding effect of the tape and prone to situations such as deviation. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem of unstable tension and easy deviation during the tape winding process in the prior art, and to propose a tape slitting, winding and unwinding device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A tape slitting, winding and unwinding device includes a bracket. A winding and unwinding roller is rotatably connected to the inner wall of the bracket. Two sets of compaction mechanisms are symmetrically and fixedly connected to one side of the bracket close to the winding and unwinding roller. The compaction mechanism is used to compact the tape on the winding and unwinding roller. The bracket is also symmetrically provided with through holes. An active block is slidably connected in the through holes. A second spring is fixedly connected between the active block and the through holes. Two sets of rotating plates are symmetrically and rotatably connected to the inner wall of the bracket. An active roller is rotatably connected between the two sets of rotating plates. A connecting plate is arranged between the active block and the rotating plates. A linkage mechanism is arranged among the winding and unwinding roller, the compaction mechanism and the active block.

[0007] Preferably, in order to facilitate the subsequent winding of the tape, the compaction mechanism includes mounting seats symmetrically and fixedly connected to the bracket. A chute is opened on one side of the two mounting seats close to each other. A slider is slidably connected inside the chute. A pressure roller is rotatably connected between the two sliders. A connection hole is opened on one side of the mounting seat close to the linkage mechanism. The shaft of the pressure roller extends to the outside through the connection hole. A first spring is fixedly connected between the slider and the chute.

[0008] For the convenience of tape compaction and tension stability, further, the linkage mechanism includes a driving wheel rotatably connected to the bracket, the driving wheel is axially connected to the winding and unwinding roller, a tensioning wheel is rotatably connected to the movable block, a driven wheel is fixedly connected to the end of the pressure roller shaft, and a belt is sleeved on the driving wheel, the tensioning wheel and the driven wheel.

[0009] For the convenience of tape winding, preferably, a motor is fixedly connected to the bracket, and the output end of the motor is axially connected to the winding and unwinding roller.

[0010] To ensure the compaction effect of the tape, further, the axis of the pressure roller and the axis of the winding and unwinding roller are located in the same vertical plane, and the bottom of the movable roller and the bottom of the pressure roller are located in the same horizontal plane.

[0011] For the convenience of tape unwinding, preferably, a guiding roller is rotatably connected to the bracket, and the guiding roller is located above the horizontal plane of the movable roller.

[0012] Compared with the prior art, the present utility model provides a tape slitting, winding and unwinding device, which has the following beneficial effects:

[0013] 1. For this tape slitting, winding and unwinding device, the linkage mechanism can drive the pressure roller to rotate synchronously, realizing the compaction of the tape during winding, reducing bubbles, wrinkles, etc. generated on the tape surface, so as to facilitate the subsequent winding of the tape.

[0014] 2. For this tape slitting, winding and unwinding device, the movable block and the second spring can ensure the stability of the linkage mechanism, and at the same time, the height of the movable roller is adjusted through the connecting plate to ensure the fixation of the tape winding position, so as to facilitate the compaction work of the tape.

[0015] Parts not involved in this device are the same as or can be implemented by the prior art. The present utility model can overcome the problems of unstable tension and easy deviation during the tape winding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiment:

[0024] Referring to Figures 1-4 , a tape slitting and winding device includes a bracket 1, a motor 2 is fixedly connected to the bracket 1, the output end of the motor 2 is axially connected to the winding and unwinding roller 3. The specific structure of the motor 2 can refer to the technical solutions in the prior art, and those skilled in the art can know, which will not be elaborated here. The motor 2 can realize forward and reverse rotation to facilitate the winding and unwinding of the tape. The winding and unwinding roller 3 is rotatably connected to the inner wall of the bracket 1. Two groups of compaction mechanisms 4 are symmetrically and fixedly connected to one side of the bracket 1 close to the winding and unwinding roller 3. The compaction mechanism 4 is used to compact the tape on the winding and unwinding roller 3; it also includes through holes 5 symmetrically opened on the bracket 1, and a movable block 6 is slidably connected in the through holes 5. It should be explained that when the movable block 6 moves in the through holes 5, it can only move along the through holes 5. A second spring 7 is fixedly connected between the movable block 6 and the through holes 5. Two groups of rotating plates 11 are symmetrically and rotatably connected to the inner wall of the bracket 1. A movable roller 12 is rotatably connected between the two groups of rotating plates 11. A connecting plate 13 is arranged between the movable block 6 and the rotating plate 11. A linkage mechanism is arranged between the winding and unwinding roller 3, the compaction mechanism 4 and the movable block 6.

[0025] Referring to Figures 1-3, the compaction mechanism 4 includes mounting seats 41 symmetrically and fixedly connected to the bracket 1. On one side of the two groups of mounting seats 41 close to each other, there are sliding grooves 42. A slider 43 is slidably connected inside the sliding groove 42. A pressure roller 44 is rotatably connected between the two groups of sliders 43. A connection hole 45 is provided on one side of the mounting seat 41 close to the linkage mechanism. The shaft of the pressure roller 44 extends to the outside through the connection hole 45. A first spring 46 is fixedly connected between the slider 43 and the sliding groove 42. When the tape is being wound, under the action of the first spring 46, the pressure roller 44 can be closely attached to the wound tape, and the height of the pressure roller 44 can be automatically adjusted according to the increase in the size of the tape reel, ensuring the stability of tape compaction.

[0026] Refer to Figure 1 , the linkage mechanism includes a driving wheel 9 rotatably connected to the bracket 1. The driving wheel 9 is connected to the shaft of the winding and unwinding roller 3. A tensioning wheel 8 is rotatably connected to the movable block 6. The end of the shaft of the pressure roller 44 is fixedly connected with a driven wheel 15. A belt 10 is sleeved on the driving wheel 9, the tensioning wheel 8 and the driven wheel 15. When winding, the driven wheel 15 is driven to rotate simultaneously through the driving wheel 9, the tensioning wheel 8 and the belt 10. While ensuring tape compaction, the tension of the tape and the fixation of the winding position can also be adjusted.

[0027] Refer to Figure 2 , the axis of the pressure roller 44 and the axis of the winding and unwinding roller 3 are located in the same vertical plane, and the bottom of the movable roller 12 and the bottom of the pressure roller 44 are located in the same horizontal plane. This can effectively avoid poor compaction effect caused by the tape contacting the previous tape too early or too late during winding.

[0028] Refer to Figures 1-2 , a guiding roller 14 is rotatably connected to the bracket 1. The guiding roller 14 is located above the horizontal plane of the movable roller 12. The guiding roller 14 can play a role in tensioning the tape.

[0029] In the present utility model, when the tape is wound up, the tape first passes through the guide roller 14 and the movable roller 12 and finally winds around the winding and unwinding roller 3. The motor 2 is started to drive the winding and unwinding roller 3 to rotate to wind up the tape. At the same time, the driving wheel 9 drives the driven wheel 15 to rotate through the tensioning wheel 8 and the belt 10, thereby driving the pressure roller 44 to rotate, realizing the compaction during the winding of the tape, and avoiding the generation of bubbles, wrinkles, etc. on the surface of the tape during winding, which may affect the subsequent winding of the tape. As the size of the tape roll increases, the slider 43 moves upward along the chute 42, so that the pressure roller 44 can reduce the influence on the winding of the tape while ensuring the compaction effect. At the same time, it drives the movable block 6 to move in the through hole 5. While ensuring the tension of the belt 10, the angle of the rotating plate 11 can be adjusted through the connecting plate 13, so that the movable roller 12 is in the same position as the tape winding position, facilitating the compaction of the tape and ensuring the tension of the tape during winding. When the tape is unwound, the principle is the same as above, but the process is opposite. During the unwinding process, the pressure roller 44 can make the unwound tape more neat, facilitating the subsequent winding work of the tape.

[0030] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
