Description

Technical Field

[0001] This utility model relates to the field of tape production technology, specifically to a tape winding structure. 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] During the tape winding operation, the tape on the outside of the rubber tube on the outside of the take-up roller is constantly wrapped, causing the diameter of the rubber tube to continuously increase. Due to the inconvenient distance between the conveyor roller and the take-up roller, the increase in the size of the rubber tube will make the tape between the two loose, which will easily cause wrinkles to occur when the tape is wound up.

[0008] Preferably, the direction of the line connecting the two sets of connecting grooves is parallel to the direction of the rubber strip conveying.

[0009] Preferably, the winding machine has a positioning groove on the front side, a locking hole on the upper part of the positioning groove, and a locking rod that matches the locking hole is slidably connected inside the first rotating arm on the rear side.

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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a tape production winding structure, including a winding machine 1. A first rotating shaft 5 is rotatably mounted on the right side of the winding machine 1. A rear first rotating arm 7 is fixedly welded to the other end of the first rotating shaft 5. A first connecting rod 8 is fixedly welded to the front side of the first rotating arm 7. A front first rotating arm 7 is fixedly welded to the other end of the first connecting rod 8. A first torsion spring 6 is fixedly welded between the rear first rotating arm 7 and the winding machine 1. The first torsion spring 6 is sleeved on the outside of the first rotating shaft 5. A second rotating shaft 11 is rotatably mounted on the other end of the two first rotating arms 7. A first pressure roller 14 is fixedly welded to the outside of the second rotating shaft 11. The first torsion spring 6 pulls the rear first rotating arm 7 and the first connecting rod 8 to cause the two first rotating arms 7 to roll the tape. The first pressure roller 14 presses the upper part of the tape roll, making it easier to flatten the tape after winding. The first rotating arm 7 has a rotating groove 9 inside, and a third rotating shaft 13 is rotatably connected inside the rotating groove 9. A second rotating arm 10 is fixedly welded to the outside of the third rotating shaft 13. A second torsion spring 12 is fixedly welded between the second rotating arm 10 and the rotating groove 9. The second torsion spring 12 is sleeved on the outside of the third rotating shaft 13. A second connecting rod 15 is fixedly welded between the two second rotating arms 10. A second pressure roller 16 is fixedly welded between the second connecting rods 15. The second torsion spring 12 pulls the second rotating arm 10, causing the second pressure roller 16 to press the conveyed tape, preventing the tape roll from increasing in radius due to tape winding, which would cause a decrease in the tension of the conveyed tape.

[0021] The winding machine 1 is rotatably connected from left to right by a dispensing roller 2, two sets of positioning rollers 3, and a taking-up roller 4. Adhesive strips 29 are fitted onto the outer sides of the dispensing roller 2, positioning rollers 3, and taking-up roller 4. The adhesive tape released from the dispensing roller 2 connects to the tape roll on the taking-up roller 4 after passing through the two sets of positioning rollers 3, thus achieving the winding operation. A first fixing ring 22 is fixedly welded to one side of the second pressure roller 16. A threaded rod 17 is rotatably installed inside the second pressure roller 16, and a movable piece 18 is threadedly connected to the outer side of the threaded rod 17. The second pressure roller... Two sets of connecting grooves 19 are provided on both sides of roller 16. Connecting plates 20 are fixedly welded to both sides of movable plate 18. Limiting rings 21 are fixedly welded through the connecting grooves 19 of the connecting plates 20. One end of the conveyed tape is tightly pressed against the first fixing ring 22. By rotating the threaded rod 17, movable plate 18 drives the limiting ring 21 to move through the connecting plates 20, so that the limiting ring 21 is tightly pressed against the other side of the tape, thus restricting the position of the conveyed tape. A positive... The second fixing ring 28 of the first fixing ring 22 ensures that the tape is in the same position throughout the conveying process; the connecting line of the two sets of connecting grooves 19 is parallel to the conveying direction of the tape strip 29 to prevent the connecting grooves 19 from contacting the conveyed tape and damaging it; a positioning groove 23 is provided on the front side of the winding machine 1, and a locking hole 24 is provided on the upper part of the positioning groove 23. A locking rod 25 that matches the locking hole 24 is slidably installed inside the first rotating arm 7 on the rear side. When the first rotating arm 7 rotates to the horizontal direction, the locking rod 25 is inserted into the locking hole 24 to lock the first rotating arm 7 and prevent the first pressure roller 14 from affecting the normal installation of the tape tube; a fixing plate 26 is fixedly welded to one end of the locking rod 25, and a spring 27 is fixedly welded between the fixing plate 26 and the first rotating arm 7. The spring 27 is sleeved on the outside of the locking rod 25. The spring 27 pulls the fixing plate 26 to make the locking rod 25 automatically insert into the locking hole 24, thereby realizing the automatic locking of the first rotating arm 7.

[0022] Working principle: In use, the tape released by the dispensing roller 2 passes through two sets of positioning rollers 3 and connects with the tape roll on the take-up roller 4 to achieve the take-up operation. The first torsion spring 6 pulls the first rotating arm 7 on the rear side and the first connecting rod 8 to move the first rotating arms 7 on both sides toward the tape roll, so that the first pressure roller 14 presses the upper part of the tape roll on the outside of the take-up roller 4, so that the tape can be flattened after take-up. The second torsion spring 12 pulls the second rotating arm 10 to make the second pressure roller 16 press the tape conveyed between the positioning roller 3 and the take-up roller 4, so as to prevent the tape roll from increasing in radius due to tape winding, which would cause the tension of the conveyed tape to decrease. When the first rotating arm 7 rotates to the horizontal direction, the spring 27 pulls the fixing plate 26 to make the locking rod 25 automatically insert into the locking hole 24 to lock the first rotating arm 7, so as to prevent the first pressure roller 14 from affecting the normal installation of the tape roll.
