Description

Technical Field

[0001] This utility model relates to the field of double-sided tape production technology, and in particular to a leveling device for double-sided tape production. Background Technology

[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, plastic film, elastomer-type pressure-sensitive adhesive, or resin-type pressure-sensitive adhesive. Both surfaces of the tape have an adhesive effect, allowing it to bond two objects together. It is a common everyday item. Some double-sided tapes have a protective release film on both adhesive sides. In the production process of this type of double-sided tape, a release film is applied to both adhesive sides to protect them, and the release film and the tape are then leveled.

[0003] Currently, most methods for leveling the release film on double-sided adhesive tape involve using a conveyor mechanism to transport the tape. During the transport process, rollers press and level the release film onto the tape surface. However, this process requires a supporting structure on the other side of the tape to cooperate with the rollers, which can affect the adhesion on the other side of the tape. Furthermore, it requires two leveling processes, resulting in low leveling efficiency for double-sided adhesive tape and indicating room for improvement. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figure 1-4 A leveling device for producing double-sided tape includes a fixed frame 1, with two unwinding components fixedly connected to the front of the fixed frame 1, a leveling component fixedly connected to the left side of the fixed frame 1, and two straightening components fixedly connected to the left side of the fixed frame 1.

[0024] The unwinding assembly is used to automatically unwind the release film, the leveling assembly is used to level the upper and lower surfaces of the release film and the tape, and the alignment assembly is used to ensure that there is no left or right position deviation during tape transmission.

[0025] The unwinding assembly includes a positioning frame 2. Rotating slots are provided on the opposite sides of the two positioning frames 2. A drive motor 3 is fixedly connected to the left side of the positioning frame 2. A rotating shaft 4 is fixedly connected to the output end of the drive motor 3. The right end of the rotating shaft 4 extends into the interior of the rotating slot and is rotatably connected to the right inner wall of the rotating slot. An unwinding roller 5 is fixedly connected to the surface of the rotating shaft 4, and the positions of the two unwinding rollers 5 are corresponding. After the drive motor 3 is started, it can drive the unwinding roller 5 to rotate through the rotating shaft 4. The release film on the surface of the unwinding roller 5 can be pasted to the upper and lower surfaces of the tape, thereby realizing automatic unwinding operation.

[0026] The leveling assembly includes a strip frame 6. A first positive and negative threaded rod 7 is rotatably connected to the upper surface of the strip frame 6. The bottom end of the first positive and negative threaded rod 7 extends into the interior of the strip frame 6 and is rotatably connected to the inner bottom wall of the strip frame 6. Two movable frames 8 are slidably connected to the inner wall of the strip frame 6, and the two movable frames 8 are respectively threaded to the positive and negative threads on the surface of the first positive and negative threaded rod 7. A fixed cavity is opened on the right side of the movable frame 8. A servo motor 9 is fixedly connected to the inner wall of the fixed cavity. A connecting shaft 10 is fixedly connected to the output end of the servo motor 9. A leveling roller 11 is fixedly connected to the surface of the connecting shaft 10. A stabilizing shaft 12 is fixedly connected to the right end of the leveling roller 11. After rotating the first positive and negative threaded rod 7, the two movable frames 8 can be driven to move closer to each other. The two movable frames 8 can drive the two leveling rollers 11 to level the release film on the upper and lower surfaces of the tape. The servo motor 9 can drive the leveling roller 11 to rotate through the connecting shaft 10, reducing the resistance generated during the contact between the release film and the leveling roller 11, and ensuring the leveling effect.

[0027] A chute is provided on the right side of the fixed frame 1. Two stabilizing plates 13 are slidably connected to the inner wall of the chute. A limiting thread groove is provided on the front of the stabilizing plate 13. The left sides of the two stabilizing plates 13 are rotatably connected to the right ends of the two stabilizing shafts 12 respectively. Two sets of limiting screw holes are provided on the front of the fixed frame 1 at the position corresponding to the chute. Each set of limiting screw holes has three holes. The inner wall of the limiting screw holes is threaded with locking bolts 14. The locking bolts 14 are adapted to the limiting thread groove. The locking bolts 14 can pass through the limiting screw holes and be inserted into the limiting thread holes on the front of the stabilizing plate 13, thereby positioning the stabilizing plate 13 in the chute. The stabilizing plate 13 and the stabilizing shaft 12 can improve the stability of the leveling roller 11 during the rotation process and prevent wobbling that would affect the leveling effect on the release film and tape.

[0028] The alignment assembly includes a right-angle frame 15. A strip frame 16 is fixedly connected to the right side of the right-angle frame 15. Two alignment blocks 17 are slidably connected to the inner bottom wall of the strip frame 16. A rectangular frame 18 is fixedly connected to the upper surface of the strip frame 16. A second positive and negative threaded rod 19 is rotatably connected to the left side of the rectangular frame 18. The right end of the second positive and negative threaded rod 19 is rotatably connected to the right inner wall of the rectangular frame 18. Two sliders 20 are slidably connected to the inner top wall of the rectangular frame 18, and the two sliders 20 are respectively threaded to the positive and negative threads on the surface of the second positive and negative threaded rod 19. The lower surfaces of the two sliders 20 are fixedly connected to the upper surfaces of the two leveling blocks 17, and the two strip frames 16 are both located at the center of the two leveling rollers 11. The tape passes through the two strip frames 16. At this time, rotating the second positive and negative threaded rod 19 can drive the two sliders 20 to move towards the opposite side. The two sliders 20 can drive the two leveling blocks 17 to move closer to each other, thereby limiting the left and right sides of the tape and ensuring that the tape will not shift left or right during transmission, making the leveling position of the two release films more accurate.

[0029] Working principle: First, the tape is passed through the two strip frames 16 and the fixing frame 1 in the forward direction. At this time, the second forward and reverse threaded rod 19 is rotated, which drives the two sliders 20 to move towards each other, thereby driving the two leveling blocks 17 to move closer to each other until the two leveling blocks 17 contact the two sides of the tape, keeping the tape in the middle of the two leveling rollers 11. At this time, the release film on the surface of the two unwinding rollers 5 is pasted onto the upper and lower surfaces of the tape. Then, the first forward and reverse threaded rod 7 is rotated, which drives the two movable frames 8 to move the two leveling rollers 11 towards the middle until the two leveling rollers 11 are in the middle of the tape. The two lower release films are pressed against the surface of the tape. At this time, the position of the stabilizing plate 13 is fixed. The stabilizing plate 13 is locked with the locking bolt 14. The two servo motors 9 are turned on. The two servo motors 9 drive the leveling rollers 11 to rotate in the opposite direction through the connecting shaft 10. Both leveling rollers 11 can rotate in the direction of tape transmission. After the tape is conveyed, it will not be offset to the left or right by the leveling block 17. The two leveling rollers 11 can press the upper and lower release films against the upper and lower surfaces of the tape, and achieve the leveling treatment of the tape. The leveling effect of the tape is good.
