Description

Technical Field

[0001] This utility model relates to the field of tape winding technology, specifically a tape winding device. Background Technology

[0002] Currently, the winding of breathable zinc oxide tape largely relies on automated winding equipment. The core process involves feeding a continuous tape substrate to a winding roller via a tension control mechanism. The winding roller then winds the tape layer by layer to form a large roll. Once the set length or diameter is reached, a cutting mechanism cuts the tape, and the finished roll is then transferred to the packaging station. However, in actual production, it has been found that after the cutting mechanism has cut the tape, the free end joints of the large roll, which have not yet undergone further cutting or transfer, are prone to drooping and displacement. This problem arises mainly from two aspects: Firstly, the substrate of the breathable zinc oxide tape itself has a certain degree of flexibility and the adhesive surface is relatively sticky. After being cut, the free end, which loses its tension constraint, lacks effective support and positioning, and is easily affected by its own weight or slight external disturbances (such as equipment vibration or airflow) and will naturally sag. Secondly, the winding rollers of existing winding devices are usually in a stationary or low-speed rotating state after the tape is cut, which cannot form a continuous constraint on the free end of the tape, causing the joint to deviate from the original winding trajectory, or even come into contact with the workbench, equipment frame, etc. and stick together. This phenomenon not only causes unnecessary waste of tape, but also interferes with subsequent cutting and packaging processes. Therefore, it is necessary to provide a tape winding device to solve the above problems. Utility Model Content

[0020] The transmission unit also includes a motor 2, a driving pulley 21, a driven pulley 22, and a transmission belt 23. The motor 2 is mounted on the workbench 1 and its output end is connected to the driving pulley 21. The driven pulley 22 is fixedly mounted on the transmission shaft 24. The transmission belt 23 is nested on the driving pulley 21 and the driven pulley 22. The drive shaft 24 has a limiting ring 27 and a handwheel 25. The handwheel 25 is fixedly connected to one end of the drive shaft 24. The driven pulley 22 is located between the gearbox 26 and the drive shaft 24.

[0021] Motor 2 is electrically connected to foot switch 3, which is located at the bottom center of workbench 1.

[0022] The diameter of the outer peripheral wall of the limiting ring 27 gradually decreases from the end closest to the gearbox 26 to the end furthest from the gearbox 26.

[0023] The cutting unit 4 also includes a housing 47 with a blade outlet 401, a blade holder 41, a cutter 42, a slide 43, a connecting rod 44, a turntable 45, and a positioning post 46. The blade holder 41 is horizontally fixedly installed inside the housing 47, and has an opening on one side that coincides with the blade outlet 401. One end of the cutter 42 is fixedly connected to the slide 43, and the slide 43 and the blade holder 41 are slidably connected left and right. The turntable 45 is rotatably connected to the interior of the housing 47 and fixedly connected to the drive shaft 452 on one side. The drive shaft 452 passes through the housing 47. A rotating shaft 451 is installed on the other side of the turntable 45. The positioning pin 46 is fixedly connected to the inner wall of the housing 47. The turntable 45 is located between the tool holder 41 and the positioning pin 46. A limiting post 431 is fixedly connected to one side of the slide block 43. The connecting rod 44 has an upward-opening notch 441, a sliding groove 442 and a connecting hole 443 from top to bottom. The limiting post 431 matches the notch 441 and is located inside the notch 441. The rotating shaft 451 slides in the sliding groove 442. The connecting hole 443 is rotatably connected to the positioning post 46.

[0024] The workbench 1 is threadedly connected to an outwardly extending bracket 6, and the tape roll 7 is rotatably mounted on the bracket 6.

[0025] In one embodiment, the operating principle of the device Specifically, the roll of tape 7 is installed on the bracket 6, and an inner core 8 is installed on the limiting ring 27 on the drive shaft 24. The inner wall of the inner core 8 abuts against the outer wall of the limiting ring 27. The joint is found on the tape roll 7, and the joint of the tape roll 7 is passed around the top of the first guide post 521, the second guide post 531 and the third guide post 532 in sequence. At this time, the back of the tape roll 7 is in contact with the first guide post 521, the second guide post 531 and the third guide post 532, and is located between the limiting sleeves 54. The front of the tape roll 7 is sticky and faces upward. The sticky part at the joint is pasted to the lower edge of the inner core 8. The handwheel 25 is turned once by holding the handwheel 25, and the foot pedal switch 3 is stepped on to start the motor 2. The motor 2 rotates and drives the drive pulley 21 to rotate, and then transmits the power to the drive shaft 24. The drive shaft 24 rotates, and the inner core 8 rotates accordingly. The tape roll 7 is continuously wound around the inner core 8. During this process, the drive shaft 24 rotates to transmit power to the gearbox 26, and then the gearbox 26 outputs power to the drive shaft 452. The drive shaft 24 drives the turntable 45 to rotate, and the rotating shaft 451 on the turntable 45 slides in the slide groove 442. The connecting rod 44 swings around the positioning pin 46 as the axis to adjust the angle. The notch 441 cooperates with the limit pin 431 to move the slide block 43 towards the exit 401, causing the cutter 42 to move towards the exit 401. After the cutter head of the cutter 42 goes out from the exit 401, it cuts the tape roll 7. Then the tape roll 7 is cut off. The motor 2 continues to rotate, on the one hand, completely winding the cut tape roll 7 onto the inner core 8, and on the other hand, retracting the cutter 42. Then the foot switch 3 is released, the motor 2 stops rotating, the wound inner core 8 is taken out and replaced with a new inner core 8, and the winding is repeated.

[0026] At this time, the end of the tape roll 7 droops on the third guide post 532 and is supported by the first guide post 521, the second guide post 531 and the third guide post 532. The length of the tape roll 7 located on the first guide post 521, the second guide post 531 and the third guide post 532 overcomes the gravity, so that the tape roll 7 stays on the first guide post 521, the second guide post 531 and the third guide post 532. At the same time, under the influence of the limiting sleeve 54, the friction of the tape roll 7 is increased, so that the tape roll 7 avoids slipping and can limit the unwinding direction of the tape roll 7, so that the tape roll 7 and the inner core 8 are always kept in the same straight line position when unwinding.

[0027] In summary, the device, by providing a first guide post 521, a second guide post 531, and a third guide post 532, supports the cut tape and, at the same time, uses a limiting sleeve 54 to make it contact the two sides of the tape, increasing friction and constraining the tape to prevent displacement or excessive sagging after cutting. By setting up a cutting unit connected to the gearbox, after the drive shaft rotates a certain number of times, the gearbox transmits power to the cutting unit. The cutter in the cutting unit cuts the tape roll, which not only improves the automation of cutting the tape roll, but also allows for precise control of the tape length on the inner core, thereby improving production efficiency and reducing labor costs.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
