Description

Technical Field

[0001] This invention relates to the field of tape production equipment, and more particularly to a tape cutting device. Background Technology

[0002] Adhesive tape consists of two parts: a substrate and an adhesive. It connects two or more unconnected objects together by bonding. Its surface is coated with an adhesive layer.

[0003] Patent application number CN202220982156.4 discloses a tape cutting device, including a rotating mechanism and a cutting mechanism. The rotating mechanism drives the tape roll to rotate, and the cutting mechanism cuts the tape roll on the rotating mechanism. The cutting mechanism includes: a first slide rail, a second slide rail, a first slider, a second slider, a first support plate, a rotating shaft, a cutting blade, and a first motor. The first slide rail is parallel to the rotating mechanism. The first and second sliders drive the cutting blade to move and cut the tape roll. The distance of the first slider can be adjusted according to actual needs, so that tape of appropriate width can be cut as needed. However, this type of cutting device cuts long tape rolls with a single cutting blade, requiring multiple movements of the cutting blade to cut the long tape roll into multiple short tape rolls, which greatly reduces the production efficiency of tape.

[0004] This invention was developed to address the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tape cutting device.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a tape cutting device, comprising a base plate with support plates fixed on both sides of the base plate. Each support plate has a support groove. A rotating shaft is positioned above the base plate, with its two ends respectively positioned within the two support grooves. The rotating shaft is driven to rotate by a limiting motor. A sliding table is also positioned above the base plate, driven to move by a positioning motor. A cutting shaft is also positioned on the sliding table, driven to rotate by a cutting motor. Multiple limiting rings slidably connected to the cutting shaft are also provided on the cutting shaft. Each limiting ring has a cutter fixed to it. Each limiting ring also has a positioning tube rotatably connected to it, with a positioning plate fixed to each positioning tube. A positioning ring is fixed to the top of each positioning plate. A support shaft is also positioned on the sliding table, driven to rotate by a support motor. A push rod is fixed to the support shaft, with fixing blocks evenly fixed to the push rod. Each fixing block has a fixing shaft fixed to it. A fixing rod rotatably connected to the fixing shaft is provided on the fixing shaft, passing through a corresponding positioning ring and slidably connected to it. The long roll of tape to be cut is fixed on the rotating shaft. The two ends of the rotating shaft are placed in the support grooves of two support plates. The limiting gear on the rotating shaft meshes with the limiting main gear. The positions of each cutter are adjusted according to the required length of tape to be cut. The screw is driven to rotate by the support motor. Since the screw is threadedly connected to the slider, the slider moves in the screw direction when the screw rotates. The rack moves with the slider, and when the rack moves, the support shaft rotates. The push rod rotates with the support shaft. Since the fixed rod passes through and slides through the positioning ring, when the push rod rotates around the support shaft, it pushes each positioning ring to move through each fixed rod, thereby driving each... The movement of a limit ring adjusts the position of two adjacent cutters. Once the cutter is in the correct position, the support motor stops, and the cutting motor drives the cutting shaft to rotate. The cutter rotates with the cutting shaft, and the positioning motor drives the lead screw to rotate. When the lead screw rotates, the slide moves towards the tape roll. After the high-speed rotating cutter contacts the tape roll, the limit motor drives the tape roll to rotate, and the cutter cuts the tape roll. This device can cut a long tape roll into multiple short tape rolls and can automatically adjust the distance between adjacent cutters, allowing a long tape roll to be cut into multiple short tape rolls in one operation.

[0008] Preferably, a limiting slave gear is fixed on the rotating shaft, and a limiting master gear is fixed at the output end of the limiting motor, wherein the limiting master gear meshes with the limiting slave gear.

[0009] Preferably, a limiting block is also provided in the support groove, and a limiting plate is fixed on the limiting block. The limiting plate is fixed to the support plate by bolts. During cutting, the limiting block holds the rotating shaft in place, preventing the rotating shaft from disengaging from the cutting groove.

[0010] Preferably, a limiting tube and a threaded tube are fixed on the slide, and a lead screw and a sliding rod are also provided above the base plate. The lead screw is fixed to the output end of the positioning motor, the lead screw passes through the threaded tube and is threadedly connected to the threaded tube, and the sliding rod passes through the limiting tube and is slidably connected to the limiting tube.

[0011] Preferably, a support gear is fixed at the bottom of the support shaft, a slider is provided on one side of the slide, a support motor is fixed on the slide, a screw is fixed at the output end of the support motor, the screw passes through the slider and is threadedly connected to the slider, a support rod is also fixed on the slide, the support rod passes through the slider and is slidably connected to the slider, and a rack is also fixed on the slider, the rack meshing with the support gear.

[0012] Compared with existing technologies, the present invention has the following advantages:

[0013] This device can cut long rolls of tape into multiple short rolls, and can automatically adjust the distance between adjacent cutters, allowing a long roll of tape to be cut into multiple short rolls at once. Attached Figure Description

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0020] Example 1:

[0021] like Figures 1 to 3 As shown, this embodiment discloses a tape cutting device, including a base plate 1, with support plates 2 fixed on both sides of the base plate 1. Each support plate 2 is provided with a support groove 3. A rotating shaft 4 is also provided above the base plate 1, with its two ends respectively set in the two support grooves 3. The rotating shaft 4 is driven to rotate by a limit motor 9. A slide table 12 is also provided above the base plate 1, and the slide table 12 is driven to move by a positioning motor 35. A cutting shaft 13 is also provided on the slide table 12, and the cutting shaft 13 is driven to rotate by a cutting motor 18. A plurality of limit rings 19 are also provided on the cutting shaft 13 and are slidably connected to the cutting shaft 13. Each limit ring 19 is fixed with a support groove 3. A cutter 20 is fixed, and a positioning tube 21 is provided on the limiting ring 19 and is rotatably connected to the limiting ring 19. A positioning plate 22 is fixed on the positioning tube 21, and a positioning ring 23 is fixed on the top of the positioning plate 22. A support shaft 24 is also provided on the slide table 12. The support shaft 24 is driven to rotate by the support motor 26. A push rod 31 is also fixed on the support shaft 24. Fixed blocks 32 are evenly fixed on the push rod 31. A fixed shaft 33 is fixed on each fixed block 32. A fixed rod 34 is provided on the fixed shaft 33 and is rotatably connected to the fixed shaft 33. The fixed rod 34 passes through the positioning ring 23 at the corresponding position and is slidably connected to the positioning ring 23. The long roll of tape 5 to be cut is fixed on the rotating shaft 4. The two ends of the rotating shaft 4 are placed in the support grooves 3 of the two support plates 2. The limiting gear 11 on the rotating shaft 4 meshes with the limiting main gear 10. The position of each cutter 20 is adjusted according to the required length of tape to be cut. The screw 27 is driven to rotate by the support motor 26. Since the screw 27 is threadedly connected to the slider 29, the slider 29 moves in the direction of the screw 27 when the screw 27 rotates. The rack 30 moves with the slider 29. When the rack 30 moves, the support shaft 24 rotates. The push rod 31 rotates with the support shaft 24. Since the fixed rod 34 passes through the positioning ring 23 and is slidably connected to the positioning ring 23, when the push rod 31 rotates around the support shaft 24, it pushes each positioning ring 23 to move through each fixed rod 34. This causes each limiting ring 19 to move, thereby adjusting the position of two adjacent cutters 20. When the cutter 20 is adjusted to the corresponding position, the support motor 26 stops, and the cutting motor 18 drives the cutting shaft 13 to rotate. The cutter 20 rotates with the cutting shaft 13, and the positioning motor 35 drives the lead screw 17 to rotate. When the lead screw 17 rotates, the slide table 12 moves towards the tape roll 5. After the high-speed rotating cutter 20 contacts the tape roll 5, the limiting motor 9 drives the tape roll 5 to rotate, and the cutter 20 cuts the tape roll 5. This device can cut a long tape roll 5 into multiple short tape rolls 5, and can automatically adjust the distance between adjacent cutters 20, so that a long tape roll 5 can be cut into multiple short tape rolls 5 at one time.
