[0002] Adhesive tapes can be classified according to their functions: high-temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure-sensitive tapes, and die-cut tapes. Different functions are suitable for different industry needs. The surface of the tape is coated with an adhesive so that the tape can stick to the object. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives; while in modern times, various polymers are widely used.

[0003] In the tape production industry, the commonly used transfer method is to directly slip the tape roll onto the positioning tube for transfer. This method has obvious drawbacks: when encountering bumps during transfer, the tape roll will shake violently on the positioning tube or even detach from the tube, causing the product to scatter from the transfer box; to secure the tape roll, workers often need to use additional straps or pads, which increases operation time and affects transfer efficiency. Therefore, a transfer device for tape production is proposed. Utility Model Content

[0019] Example 1 In the current technology of tape production, the commonly used transfer method is to directly slip the tape roll onto the positioning tube for transfer. This method has obvious drawbacks: when encountering bumps during transfer, the tape roll will shake violently on the positioning tube or even detach from the tube, causing the product to scatter from the transfer box; to secure the tape roll, workers often need to use additional straps or pads, which increases operation time and affects transfer efficiency.

[0020] Please see Figure 1-6This utility model provides a technical solution: a transfer device for tape production, including a transfer box 1 and several adjustment components 4. Several positioning support rods 2 are connected inside the transfer box 1 through the adjustment components 4. The top of the positioning support rods 2 is provided with a limiting component 3. The bottom of the transfer box 1 is provided with a trolley 5, which drives the transfer box 1 to move.

[0021] The limiting assembly 3 includes a straight rod 31, a movable plate 37, and a spring 311. A cylinder 35 is fixedly connected to the top of the movable plate 37. The bottom end of the straight rod 31 is movably inserted into the cylinder 35. A heart-shaped guide groove 38 is provided on one side of the movable plate 37. A cavity 6 is provided inside the positioning support rod 2. A through groove 7 is provided on the top wall of the cavity 6. The straight rod 31 movably passes through the through groove 7. The spring 311 is sleeved on the outside of the straight rod 31. One end of the spring 311 is fixedly connected to the side wall of the through groove 7, and the other end of the spring 311 is fixedly connected to the outside of the straight rod 31. When the straight rod 31 moves downwards, it compresses the spring 311. 1. Energy storage: Spring 311 is in an extended state under natural conditions. When the straight rod 31 moves downward, it is compressed and stores energy. After the straight rod 31 loses external force, spring 311 rebounds and pushes the straight rod 31 upward to reset. The moving plate 37 is slidably connected to the cavity 6 via a slide rail and moves up and down with the cylinder 35 within the cavity 6. The bottom of the straight rod 31 is inserted into the cylinder 35 and fixedly connected to a moving block 36. The moving block 36 is slidably connected to the cylinder 35, and its diameter is larger than that of the straight rod 31. When the straight rod 31 moves up and down within the through groove 7, it drives the moving block 36 to move up and down within the cylinder 35. When the straight rod 31 is pressed down, the moving block 36 first slides a certain distance within the cylinder 35 (ineffective stroke) before pushing the cylinder 35 to drive the heart-shaped guide groove 38. This two-stage stroke can prevent accidental activation (requiring a large pressing force to trigger) and ensure that the protrusion 310 completes the trajectory of the heart-shaped guide groove 38. The pre-compression design of spring 311 further ensures the initial position stability of the straight rod 31.

[0022] Inside cavity 6, a rotating block 39 is rotatably connected via a rotating shaft 8. A protrusion 310 is fixedly connected to one side of the rotating block 39 and is inserted into a heart-shaped guide groove 38. Several second connecting rods 34 are evenly hinged to the top of the positioning support rod 2. One end of each second connecting rod 34 is hinged to a first connecting rod 33. A pressing plate 32 is fixedly connected to the top of the straight rod 31. The end of the first connecting rod 33 away from the second connecting rod 34 is hinged to the bottom of the pressing plate 32. In normal state, the limiting component 3 is retracted, and the first connecting rod 33 and the second connecting rod 34 are retracted. The tape is then placed on the positioning support. When the button plate 32 is pressed behind the outside of the rod 2, the button plate 32 drives the straight rod 31 to move down, which in turn drives the hinged first connecting rod 33 to unfold downward. The second connecting rod 34 unfolds in cooperation with the first connecting rod 33. The unfolded diameter is much larger than the diameter of the tape, which limits the tape and prevents the tape from shaking or falling off the positioning support rod 2 during transportation. The top of the positioning support rod 2 is provided with several limiting blocks 9. The limiting blocks 9 are staggered with the second connecting rod 34. The limiting blocks 9 limit the button plate 32 and protect the first connecting rod 33 and the second connecting rod 34 from excessive compression damage.

[0023] Working principle or structural principle: The heart-shaped guide groove 38 is an asymmetrical heart-shaped groove. In the normal state, the connecting rod is retracted, and the tape is placed on the outside of the positioning support rod 2. When it is necessary to fix the tape, the operator presses the pressing plate 32, and the straight rod 31 moves downward, driving the moving block 36 to move down inside the cylinder 35 to the bottom of the cylinder 35. Then, the cylinder 35 is pushed to move the moving plate 37 down synchronously. At this time, the protrusion 310 on the rotating block 39 slides upward along the left track of the heart-shaped guide groove 38 until it reaches the top groove and automatically locks. The position of the protrusion 310 is as follows: Figure 6 As shown, during this process, the straight rod 31 unfolds through the hinged first link 33 and second link 34 to form a stable limiting structure, and the link is as follows: Figure 3 In the unfolded state shown, spring 311 is compressed and stores energy. When it is necessary to release the limit, simply press the button 32 again, and the protrusion 310 will slide back to its initial bottom position along the right side of the heart-shaped guide groove 38. The position of the protrusion 310 is as shown. Figure 5 In the state shown, spring 311 releases its elastic force to push straight rod 31 back to its original position, and the linkage mechanism retracts accordingly, allowing the tape to be easily removed. The linkage... Figure 1 The image shows the retracted state. The protrusion 310 moves along the trajectory of the heart-shaped guide groove 38 (see...). Figure 5 , Figure 6 To achieve locking and releasing, spring 311 should be inspected and maintained regularly, and replaced promptly if any spring is found to be defective.

[0024] Example 2 The adjustment component 4 includes several inserts 41 and T-shaped sliders 42. The inserts 41 are evenly embedded in the inner bottom wall of the transfer box 1. The inserts 41 have grooves 43 that fit the T-shaped sliders 42. The positioning support rod 2 is slidably connected to the grooves 43 through the T-shaped sliders 42 to move back and forth on the top of the inserts 41. The inner side wall of the grooves 43 has several slots 44 that fit the T-shaped sliders 42. Pulling the positioning support rod 2 upward causes the T-shaped sliders 42 to disengage from the slots 44. After sliding along the grooves 43 to the target position, it is released. The T-shaped sliders 42 are locked into the corresponding slots 44 due to their own weight. The T-shaped sliders 42 move downward under their own weight and are embedded in the slots 44, realizing quick adjustment and quick fixation of the position.

[0025] In terms of working principle or structural principle, when it is necessary to adjust the position of the positioning support rod 2, simply pull the positioning support rod 2 upward to raise the T-shaped slider 42 until it is disengaged from the slot 44. After moving it along the slide groove 43 to the appropriate position, release it. The weight of the positioning support rod 2 will push the T-shaped slider 42 downward and lock it in the slot 44, thus realizing the rapid displacement adjustment of the positioning support rod 2.

[0026] In summary, the heart-shaped asymmetrical guide groove 38 design of the limiting component 3 of this utility model allows for easy operation. Pressing the button plate 32 causes the straight rod 31 to move downwards, which in turn pushes the cylinder 35 via the moving block 36, causing the moving plate 37 to move downwards. The protrusion 310 of the rotating block 39 rises along the left side of the heart-shaped guide groove 38 to the top groove and locks in place. Simultaneously, the first connecting rod 33 and the second connecting rod 34 unfold to form a limiting structure, preventing the tape from detaching from the positioning support rod 2 due to external bumps or shaking during transport. The spring 311 is compressed and stores energy. Upon a second press, the protrusion 310 slides back to the bottom along the right side, and the spring 311 pushes the straight rod 31 to reset, causing the connecting rod to retract. The positioning support rod 2 can be moved within the slide groove 43 via the T-shaped slider 42 and quickly positioned using the slot 44, enabling convenient adjustment. This design achieves a "press-lock-press again-release" cyclic action through the heart-shaped guide groove 38, making operation simple and reliable.
