Description

Technical Field

[0001] This utility model relates to the field of tape and paper tube cutting technology, and in particular to a high-precision tape and paper tube cutting device. Background Technology

[0002] In the manufacturing process of adhesive tape, the tape needs to be wound onto a paper tube. This paper tube is typically a long, cylindrical shape that needs to be cut into multiple smaller tubes as needed. Currently, the cutting is done manually by inserting the paper tube into a rotating shaft, with a rotating cutter approaching the long cylindrical tube on the shaft for cutting. Existing cutting devices require manual unloading, resulting in slow unloading efficiency after the paper tube is cut, thus reducing the overall cutting efficiency of the adhesive tape paper tubes.

[0003] Existing technology, patent number CN219748135U, discloses a tape paper tube cutting device. By adjusting the coordination between the motor, threaded rod, movable rod, horizontal guide post, and collar, the movable rod is moved horizontally, causing the collar to detach the tape paper tube after it has been cut from the side wall of the rotating spindle, thus completing the unloading of the tape paper tube and improving the cutting efficiency. However, in actual use, during the cutting process, when more than half of the paper tube has been cut, some compression occurs between the multiple segmented paper tubes, causing a deviation in the cutting angle and affecting the cutting accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a high-precision cutting device for tape and paper tubes.

[0005] This utility model is achieved through the following technical solution:

[0006] A high-precision tape and paper tube cutting device includes a base frame, two brackets fixedly connected to the inner side of the base frame, a cylinder fixedly connected to the inner wall of the base frame, a fixed frame slidably connected to the top of the brackets, a servo motor one fixedly connected to one side of the fixed frame, a rotating roller fixedly connected to the output end of the servo motor one, the outer side of the rotating roller rotatably connected to the inner side of the fixed frame, multiple blades fixedly connected to the outer side of the rotating roller, a servo motor two fixedly connected to one side of the base frame, a locking rod one fixedly connected to the output end of the servo motor two, a bracket fixedly connected to the other side of the base frame, a locking rod two rotatably connected to the inner side of the bracket, a fixed cylinder slidably connected to the outer side of both locking rod one and locking rod two, bolts inserted into the outer side of the fixed cylinder, an expansion and positioning mechanism provided on the outer side of the base frame, and a cleaning mechanism provided on one side of the fixed frame.

[0007] By adopting the above technical solution: using the snap-fit ​​of two fixed cylinders and bolts, the expansion and positioning mechanism can be disassembled and installed with the base frame, and good transmission effect is ensured. Then, multiple blades are used to cut the paper tube.

[0008] As a further description of the above technical solution: the expansion and positioning mechanism includes a main shaft, both ends of which are respectively engaged with one end of a locking rod 1 and one end of a locking rod 2. A washer is rotatably connected to the outside of the main shaft, and an outer cylinder is rotatably connected to the outside of the main shaft. Two fixed discs are fixedly connected to the outside of the main shaft, and a screw 1 is inserted into the outside of the fixed disc. One end of the screw 1 is threadedly connected to the outside of the outer cylinder. Multiple support rods 1 are fixedly connected to the outside of the main shaft. Support rods 2 are slidably connected to the outside of support rods 1. An arc-shaped arm is hinged to one end of support rod 2. A sliding groove is opened on the inner side of the arc-shaped arm. A support plate is hinged to one end of the arc-shaped arm. Multiple guide rods are fixedly connected to the inner side of the outer cylinder. Multiple openings are opened on the outer side of the outer cylinder. The outer side of the guide rod is slidably connected to the inner side of the sliding groove.

[0009] By adopting the above technical solution: by utilizing the counter-rotation of the outer cylinder and the main shaft, multiple support plates can expand towards the inner wall of the paper tube, so that the paper tube can be fixed on the outside of the outer cylinder. Furthermore, during the cutting process, each small paper tube in the cutting process is also individually supported, so that the cutting of the small paper tube remains stable, thereby maintaining high-precision cutting.

[0010] As a further description of the above technical solution: the cleaning mechanism includes a rotating rod, the outer side of which is rotatably connected to the inner side of the fixed frame, and two screws are inserted into both ends of the rotating rod. One end of the screw is threadedly connected to the outer side of the fixed frame. Two guide plates are fixedly connected to the outer side of the rotating rod, and a retaining strip is slidably connected to one side of the guide plate. Multiple openings are provided on one side of the retaining strip.

[0011] By adopting the above technical solution, the rotation of the rotating rod allows the two clamping bars to clean the outer walls of multiple blades in a cyclical manner, without having to stop the device to clean, thus improving the cutting efficiency of the device.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention, by setting up an expansion and positioning mechanism, utilizes multiple support plates to expand and support the inner wall of the paper tube at multiple points, which can support various types of paper tubes and keep the paper tube stable during the cutting process. This avoids the paper tube shifting due to insufficient support after it has been cut to more than half its length, thus maintaining high-precision cutting efficiency and improving the yield of paper tube cutting.

[0014] Meanwhile, by setting up a cleaning mechanism, compared with existing technologies, the blades can be cleaned in a timely manner during the cutting process, avoiding unevenness at the cutting edge of the paper tube. At the same time, the clamping strip can be replaced and cleaned without stopping the machine, ensuring the timeliness of blade cleaning and reducing the frequency of equipment downtime caused by blade cleaning, thereby improving the cutting efficiency of the cutting device.

[0027] The embodiments disclosed in this application are as follows: Figure 1-8 The high-precision tape and paper tube cutting device shown includes a base frame 1. Two brackets 2 are fixedly connected to the inner side of the base frame 1. A cylinder 3 is fixedly connected to the inner wall of the base frame 1. A fixed frame 4 is slidably connected to the top of the brackets 2. A servo motor 5 is fixedly connected to one side of the fixed frame 4. A rotating roller 6 is fixedly connected to the output end of the servo motor 5. The outer side of the rotating roller 6 is rotatably connected to the inner side of the fixed frame 4. Multiple blades 7 are fixedly connected to the outer side of the rotating roller 6. A second servo motor 8 is fixedly connected to one side of the base frame 1. A locking rod 9 is fixedly connected to the output end of the second servo motor 8. A bracket 10 is fixedly connected to the other side of the base frame 1. The inner side of the frame 10 is rotatably connected to the second clamp rod 11. The outer sides of the first clamp rod 9 and the second clamp rod 11 are slidably connected to the fixing cylinder 12. The outer side of the fixing cylinder 12 is inserted with the bolt 13. The outer side of the base frame 1 is provided with an expansion and positioning mechanism. The side of the fixing frame 4 is provided with a cleaning mechanism. The cylinder 3 pushes the fixing frame 4 to drive the rotating roller 6 and the blade 7 to slide on the top of the two brackets 2. Then, the fixing cylinder 12 on the outer side of the first clamp rod 9 and the second clamp rod 11 is used to sleeve the interlocked main shaft 14 and is fixed by the bolt 13, so that the second servo motor 8 can effectively drive the main shaft 14.

[0028] Reference Figure 3 and Figure 8As shown, the expansion and positioning mechanism includes a main shaft 14, with both ends of the main shaft 14 respectively engaged with one end of a locking rod 19 and one end of a locking rod 21. A washer 15 is rotatably connected to the outside of the main shaft 14, and an outer cylinder 16 is rotatably connected to the outside of the main shaft 14. Two fixed discs 17 are fixedly connected to the outside of the main shaft 14, and screws 18 are inserted into the outside of the fixed discs 17. One end of screws 18 is threaded to the outside of the outer cylinder 16. Multiple support rods 19 are fixedly connected to the outside of the main shaft 14, and support rods 20 are slidably connected to the outside of support rods 19. An arc-shaped arm 21 is hinged to one end of support rod 20. A sliding groove 22 is opened on the inner side of the arc-shaped arm 21. The outer cylinder 16 is hinged to a support plate 24. Multiple guide rods 23 are fixedly connected to the inner side of the outer cylinder 16. Multiple openings are provided on the outer side of the outer cylinder 16. The outer side of the guide rods 23 is slidably connected to the inner side of the slide groove 22. By rotating the main shaft 14 and the outer cylinder 16 in opposite directions, multiple arc-shaped arms 21 on the inner side of the main shaft 14 will slide and guide the corresponding guide rods 23 on the inner side of the outer cylinder 16. The multiple arc-shaped arms 21 can drive the support plate 24 to expand and position the inner wall of the paper tube. Then, the screws 18 on the outer side of the two fixed plates 17 are threaded to the outer side of the outer cylinder 16, so that the outer cylinder 16 and the main shaft 14 stop rotating, thus completing the positioning of the paper tube.

[0029] Reference Figure 2 and Figure 5 As shown, the cleaning mechanism includes a rotating rod 25, which is rotatably connected to the inner side of the fixed frame 4. Both ends of the rotating rod 25 are fitted with screws 26, one end of which is threaded to the outer side of the fixed frame 4. Two guide plates 27 are fixedly connected to the outer side of the rotating rod 25. A retaining strip 28 is slidably connected to one side of the guide plate 27. Multiple openings 29 are provided on one side of the retaining strip 28. By pulling out the screws 26 from the inner side of the rotating rod 25 and the fixed frame 4, the rotating rod 25 and the two guide plates 27 can be rotated and their positions interchanged, allowing the used retaining strip 28 to be rotated out. This ensures that the retaining strip 28 can be safely disassembled and cleaned while the blade 7 is rotating.

[0030] The working principle of this utility model is as follows: When performing high-precision cutting of the tape paper tube, firstly, pull out the two bolts 13 from the inner side of the corresponding clamping rod 19, clamping rod 21, fixed cylinder 12, and main shaft 14. Then, move the two fixed cylinders 12 towards the side of the servo motor 28 and the bracket 10 respectively, so that the fixed cylinders 12 can be separated from the connection between clamping rod 19, clamping rod 21, and main shaft 14. Then, remove the main shaft 14 and outer cylinder 16 from the inner side of the base frame 1. After that, put the paper tube into the outer side of the outer cylinder 16. Then, the operator holds the outer side of the outer cylinder 16 and rotates the main shaft 14, so that the main shaft 14 can drive the outer support rod 19 and support rod 20 to push the arc arm 21, and through the slide groove 22 and guide rod 23... The sliding guide allows the arc arm 21 to extend the support plate 24 to the outside of the outer cylinder 16. During the extension process, the outer cylinder 16 expands the inner wall of the paper tube, allowing the paper tube to be fixed to the outside of the outer cylinder 16. Then, the screws 18 on the outside of the two fixing plates 17 are threaded to the corresponding positions on the outside of the outer cylinder 16, so that the outer cylinder 16 can be fixed to the main shaft 14 and will not loosen. Then, the main shaft 14, the outer cylinder 16 and the paper tube are put back into the inside of the base frame 1. Then, the two ends of the main shaft 14 are fixed to one side of the first clamp 9 and the second clamp 11. Then, the servo motor 28 drives the first clamp 9 to drive the main shaft 14, so that the main shaft 14 can drive the outer cylinder 16 and the paper tube to rotate.

[0031] Then, the cylinder 3 is activated to push the fixed frame 4, which in turn moves the rotating roller 6 and the blades 7 to one side of the paper tube. The servo motor 5 drives the rotating roller 6 to rotate multiple blades 7, allowing the multiple blades 7 to cut the paper tube. During the cutting process, the retaining strip 28 on one side and multiple openings 29 can clean the edges of the cut blades 7 to prevent large impurities from adhering to the outside of the blades 7. After cleaning for a period of time, the screw 26 can be turned to loosen the limit on the fixed frame 4, allowing the rotating rod 25 to rotate. The used retaining strip 28 on one side of the rotating rod 25 can be rotated 180 degrees to the outside, allowing the unused retaining strip 28 on the other side to continue cleaning the multiple blades 7. The removed retaining strip 28 is then pulled out from inside the guide plate 27 for replacement. Finally, the multiple blades 7 complete the cutting of the paper tube.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
