Abstract
Description
Technical Field
[0001] This utility model relates to the field of tape production technology, specifically to a fully automatic tape production slitting device. Background Technology
[0002] In the adhesive tape manufacturing industry, there is always a plastic or paper tube in the middle of the roll of transparent or packaging tape, which is the sleeve used to wrap the adhesive tape. During production, multiple sleeves can be strung together on a long roller to facilitate the simultaneous wrapping of adhesive tape by multiple sleeves.
[0003] In automated production, tape rolls are typically placed inside take-up rollers. The tape is wound onto the rolls by the rotation of the take-up rollers. When enough tape is wound around the outside of the rolls, the tape needs to be cut manually to produce a single set of tape. This manual cutting method increases the workload of workers, and because the tape strips are too long, the cut surfaces are prone to being uneven. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution: a fully automatic tape production slitting device, including a mounting frame 1 and a processing roller 13. A control box 2 is fixedly welded to the front side of the mounting frame 1. A first bevel gear 5 is rotatably mounted on the upper inner side of the control box 2. A second bevel gear 6 is meshed with both sides of the first bevel gear 5. A first threaded rod 7 is fixedly welded to the tail of the second bevel gear 6. The tail of the first threaded rod 7 is rotatably connected to the inner wall of the control box 2. A first sliding rod 8 is fixedly welded inside the control box 2. Two sets of upper lugs 9 are threadedly mounted on the outer side of the first threaded rod 7. Two sets of lower lugs 9 are slidably mounted on the outer side of the first sliding rod 8. A first moving block 10 is fixedly welded between the upper and lower lugs 9. A rotating shaft 11 is rotatably mounted on the front of the first moving block 10. By rotating the first bevel gear 5, the second bevel gear 6 drives the first threaded rod 7 to rotate, thus producing tape. The movable lug 9 moves along the first sliding rod 8, thereby driving the first moving block 10 to move to both sides, increasing the distance between the two sets of processing rollers 13, thus straightening the tape. A second motor 25 is installed on the upper flange of one side control box 2. Mounting plates 31 are fixedly welded to the middle of one side of the two control boxes 2 facing each other. A second threaded rod 27 is rotatably installed between the two mounting plates 31. A second transmission belt 26 is sleeved on the outside of the power end of the second threaded rod 27 and the second motor 25. A second moving block 29 is threaded on the outside of the second threaded rod 27. A cutting blade 30 is fixedly welded to the upper part of the second moving block 29. The height of the cutting blade 30 is higher than the tape connection between the two sets of processing rollers 13. The second motor 25 drives the second threaded rod 27, thereby driving the second moving block 29 to move. The cutting blade 30 cuts the straightened tape.
[0020] A second sliding rod 28 is fixedly welded between the two mounting plates 31. A second moving block 29 is slidably mounted on the outside of the second sliding rod 28 to ensure smooth movement of the second moving block 29. A first follower rod 14 that matches the follower groove 12 is fixedly welded to one side of the processing roller 13. A sliding groove 15 is opened inside the other side of the processing roller 13. A sliding piece 16 is slidably mounted inside the sliding groove 15. A second follower rod 18 that matches the follower groove 12 is fixedly welded to one side of the sliding piece 16. The sliding piece 16 and the follower groove 12 are... A spring 17 is fixedly welded to the outside of the second follower rod 18. By inserting the first follower rod 14 into the follower groove 12 on one side, the second follower rod 18 moves along the sliding groove 15, ensuring that the second follower rod 18 is aligned with the follower groove 12 on the other side. The spring 17 pulls the sliding plate 16, causing the second follower rod 18 to be inserted into the follower groove 12, ensuring that the rotating shaft 11 can drive the processing roller 13 to rotate. Two sets of first motors 19 are installed on the upper flange of the control box 2. A first transmission belt 20 is sleeved on the outside of a motor 19 and a rotating shaft 11. The first motor 19 drives the rotating shaft 11 to rotate through the first transmission belt 20, thereby driving the processing roller 13 to rotate. Two sets of rotating rods 21 are rotatably mounted on the front side of the control box 2. A rotating plate 22 is fixedly welded to the other end of the rotating rod 21. A push rod 23 is fixedly welded to the other end of the rotating plate 22. The push rod 23 is close to the inside of the first transmission belt 20. A torsion spring 24 is fixedly welded between the rotating plate 22 and the control box 2. The torsion spring 24 is sleeved on the outside of the rotating rod 21. The torsion spring 24 pulls the rotating plate 22 to make the push rod 23 close to the inside of the first transmission belt 20, ensuring that the first transmission belt 20 remains taut when the first moving block 10 moves. A mounting groove 3 is opened on the rear side of the mounting frame 1. A third motor 4 is installed in the flange inside the mounting groove 3. The power end of the third motor 4 penetrates the control box 2 and is connected to the coupling of the first bevel gear 5. The third motor 4 provides power to the first bevel gear 5 and is installed in the mounting groove 3 to prevent it from affecting the normal installation of the mounting frame 1.
[0021] Working principle: In use, the first follower rod 14 is inserted into the follower groove 12 on one side, and the second follower rod 18 moves along the sliding groove 15, thus ensuring that the second follower rod 18 is facing the follower groove 12 on the other side. The spring 17 pulls the sliding piece 16 to insert the second follower rod 18 into the follower groove 12, thereby installing the processing roller 13. The processing rollers 13 convey the tape, thus winding the tape to the outside of the tape tube. After the tape tube is wound, the third motor 4 drives the first bevel gear 5, and the second bevel gear 6 drives the first threaded rod 7 to rotate, which drives the lug 9 to move along the first sliding rod 8, thereby driving the first moving block 10 to move to both sides, increasing the distance between the two sets of processing rollers 13, thereby straightening the tape. The second motor 25 drives the second threaded rod 27, thereby driving the second moving block 29 to move. The cutting blade 30 cuts the straightened tape, realizing automatic cutting of the tape after winding.
