Description

Technical Field

[0001] This invention relates to the field of tape cutting, specifically to an auxiliary cutting device for insulating tape with dustproof function. Background Technology

[0002] Insulating tape is widely used, and its production is becoming increasingly automated. Currently, there are generally two methods for slitting tape. One method involves using a slitting machine to pre-cut the inner liner according to size requirements, placing the cut inner liner on a rotating roller, and then mounting the roller on a cutting machine to cut the tape into multiple rolls. The other method involves directly placing the entire tape roll on a cutting machine for cutting. This method eliminates the need to pre-cut the inner liner, but the tape roll is placed on a tension roller. Since the length of the tape roll is often inconsistent, only one end of the roll is usually fixed during cutting for ease of installation and removal, leaving a gap between the other end and the tension roller. This causes the tape roll to wobble during cutting, resulting in uneven cutting. Furthermore, inaccurate blade alignment can cause significant deformation of the inner liner, affecting the quality of the cut tape roll. Summary of the Invention

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] In one embodiment, please refer to the appendix to the specification. Figure 1-14 As shown, the present invention discloses an auxiliary cutting device for insulating tape with dustproof function, comprising a frame 1, a left support 12 and a right support 11 on the frame 1, a cutting mechanism 5 for cutting tape on the frame 1, a guide rail 13 on the frame 1, the cutting mechanism 5 sliding on the guide rail 13, a tensioning mechanism 2 above the frame 1, one end of the tensioning mechanism 2 being installed inside the left support 12, the tensioning mechanism 2 being used to tension the tape roll to be cut, a support mechanism 4 below the tensioning mechanism 2, the tensioning mechanism 2 being mounted on the left support 12, the support mechanism 4 being used to stabilize the rotation of the tensioning mechanism 2 to cooperate with the cutting mechanism 5 for cutting; a locking mechanism 3 is provided on the left support 12, the locking mechanism 3 being used to compress the tensioning mechanism 2 to tighten it and lock the tightened tensioning mechanism 2.

[0032] The tape roll is cut by the cutting mechanism 5, which generates dust during the cutting process and can absorb the dust. The tensioning mechanism 2 tightens both ends of the tape roll to be cut, making the middle of the tape roll hollow, which facilitates the cutting mechanism 5 in cutting the tape roll. The support mechanism 4 supports the tensioning mechanism 2, making the rotation of the tensioning mechanism 2 more stable after the tape roll is tightened. The locking mechanism 3 locks the tensioning mechanism 2, preventing it from loosening after tightening, so that the tape roll to be cut can be efficiently cut with the cutting mechanism 5. When the locking mechanism locks the tensioning mechanism 2, the tensioning mechanism 2 is just completed and at the same time, the tensioning mechanism 2 clamps the support mechanism 4 to the bracket, making the support mechanism 4 more stable during the support process.

[0033] The tensioning mechanism 2 includes a tensioning roller 21 with one end located inside the left support 12 and the other end connected to the support mechanism 4. A tensioning component 22 is provided on the tensioning roller 21. An extrusion groove 26 is provided on the tensioning roller 21, which cooperates with the tensioning component 22. An inner rod 25 is provided inside the tensioning roller 21. The tensioning component 22 is used to tension one end of the tape roll. A positioning component 23 is provided on the tensioning roller 21 to position the other end of the tape roll. A limit component 24 is provided on the tensioning roller 21 to limit the swaying of the support mechanism 4. The inner rod 25 is pressed by the locking mechanism 3 and moves inside the tensioning roller 21. The inner rod 25 pushes the tensioning component 22 to tighten the inner wall of the tape roll. Simultaneously, the inner rod 25 pushes the positioning component 23 to tighten the other end of the tape roll, and the inner rod 25 pushes the limit component 24 to limit the support mechanism 4.

[0034] The tensioning assembly 22 includes a first rod groove 225 disposed on the tensioning roller 21. A push rod 222 is disposed inside the first rod groove 225. A tensioning block 221 is disposed above the push rod 222. A first baffle 224 is disposed on the push rod 222. A first elastic element 223 is disposed on one side of the first baffle 224 and sleeved on the tensioning block 221. The first elastic element 223 is used to drive the push rod 222 to reset. The end of the push rod 222 is disposed inside the extrusion groove 26.

[0035] A servo motor is provided at the end of the tension roller 21 to drive the tension roller 21 to rotate. When the tension roller 21 rotates, it drives the tape roll to rotate, and the cutting mechanism 5 cuts the tape roll. When the locking mechanism 3 pushes the inner rod 25 to move, the inner rod 25 drives the extrusion groove 26 to move. When the extrusion groove 26 moves, it extrudes the end of the top rod 222. The movement of the top rod 222 drives the tension block 221 to move. The tension block 221 moves toward the outside of the tension roller 21. The tape roll is sleeved on the tension roller 21. The movement of the tension block 221 tightens the tape roll. When the extrusion groove 26 moves with the inner rod 25 to the end of the top rod 222, the top rod 222 is reset under the action of the first elastic member 223. At this time, the tension block 221 is stored inside the first rod groove 225.

[0036] The positioning component 23 includes a first opening 235 and a second opening 2313 disposed on the tension roller 21. A toggle lever 231 is disposed inside the first opening 235, and a second elastic element 232 is disposed on the toggle lever 231. The second elastic element 232 is used to push the toggle lever 231 to reset. A plurality of limiting blocks 236 are disposed on the inner rod 25, and the toggle lever 231 abuts against the limiting blocks 236. A first retaining plate 234 is disposed inside the tension roller 21, and an opening groove 233 is disposed at the end of the first retaining plate 234. The second elastic element 232 is disposed inside the opening groove 233, and the toggle lever 231 is slidably connected to the opening groove 233. A clamping plate 234 has multiple inner cavities 238 at its end. A third elastic element 237 is provided inside the inner cavity 238. A guide plate 239 is provided at the end of the third elastic element 237. The guide plate 239 is located inside the inner cavity 238. A second clamping plate 2310 is connected to the end of the guide plate 239. The second clamping plate 2310 moves inside the tension roller 21. A plurality of protruding first top blocks 2311 are provided on the second clamping plate 2310. A plurality of second top blocks 2312 are provided on the inner rod 25. The second top blocks 2312 move with the inner rod 25 and squeeze the first top blocks 2311, forcing the second clamping plate 2310 to pass through the second opening 2313 and position the tape roll.

[0037] When it is necessary to fix the other end of the tape roll, the end of the tape roll can be positioned by the positioning component 23; in order to accommodate tape rolls of different lengths; push the actuating lever 231 to move, the actuating lever 231 drives the first clamping plate 234 to move. At this time, the actuating lever 231 is squeezed by the limiting block 236, and the actuating lever 231 will move towards the outside of the tensioning roller 21. When the end of the actuating lever 231 slides past the limiting block 236, the second elastic element 232 pushes the actuating lever 231 into one side of the limiting block 236. At this time, the limiting block 236 will restrict the reverse movement of the actuating lever 231, thereby achieving the limiting. When it is necessary to move the actuating lever 231 to drive the first clamping plate 234 to move in the opposite direction, pull the actuating lever 231 outward so that the end of the actuating lever 231 does not contact the limiting block 236; by setting The first clamping plate 234 moves, causing the second clamping plate 2310 to move, thereby adjusting the position of the second clamping plate 2310 at the second opening 2313. This allows the second clamping plate 2310 to move inside the tensioning roller 21. The second clamping plate 2310 moves to the end of the corresponding tape roll. Then, the inner rod 25 moves, causing the second top block 2312 to move. The second top block 2312 moves to the end of the first top block 2311, pressing the first top block 2311. The first top block 2311 moves towards the outside of the tensioning roller 21. Since the guide plate 239 at the end of the second clamping plate 2310 moves inside the inner cavity 238, the second clamping plate 2310 is pressed against the inner wall of the tape roll, thereby tightening the other end of the tape roll and achieving the positioning of the tape roll.

[0038] The limiting component 24 includes a limiting wheel 241 disposed on the inner rod 25. A support wheel 242 is disposed on one side of the limiting wheel 241. The support wheel 242 slides on the inner rod 25. A limiting plate 244 is disposed on one side of the support wheel 242. The limiting plate 244 is used to limit the movement of the support wheel 242. A support plate 243 is disposed on one side of the limiting plate 244. The support plate 243 is used to stabilize the support wheel 242.

[0039] The limiting wheel 241 can move synchronously with the inner rod 25. When the limiting wheel 241 moves onto the support mechanism 4, the limiting wheel 241 presses against the support mechanism 4, thereby locking the support mechanism 4. The supporting wheel 242 can support one end of the tensioning roller 21, which facilitates the tensioning roller 21 to drive the tape roll to rotate stably. The support plate 243 can support the rotation of the supporting wheel 242. The limiting plate 244 can block the movement of the supporting wheel 242 and prevent the supporting wheel 242 from falling off the support plate 243.

[0040] The support mechanism 4 includes a hydraulic rod 410 mounted on the right support 11. One end of the hydraulic rod 410 is connected to a support plate 41. A stabilizing sleeve 49 is mounted on the frame 1. The support plate 41 is rotatably connected to the stabilizing sleeve 49. A guide groove is provided inside the support plate 41. A first guide rod 42, a bent rod 43, and a second guide rod 44 are provided inside the guide groove. The first guide rod 42 and the second guide rod 44 are movably connected by the bent rod 43.

[0041] The stabilizing sleeve 49 has a slot 48 inside, and a locking rod 47 is movably disposed inside the slot 48. A fourth elastic element 46 is sleeved on the locking rod 47. The fourth elastic element 46 is used to push the locking rod 47 to reset. A pressing head 45 is disposed on the top of the locking rod 47. The pressing head 45 abuts against the second guide rod 44.

[0042] The surface of the limiting wheel 241 that contacts the first guide rod 42 is an arc surface, and the end of the first guide rod 42 is an arc surface. When the limiting wheel 241 moves and contacts the first guide rod 42, it smoothly presses the first guide rod 42 downward. When the first guide rod 42 moves downward inside the guide groove, it presses the bent rod 43. The bent rod 43 moves inside the guide groove. Since the connection points between the bent rod 43 and the first guide rod 42 and the second guide rod 44 are all movable, under the limiting action of the guide groove, the first guide rod 42 pushes the second guide rod 44 to move through the bent rod 43. The rod 44 moves and presses against the extrusion head 45. The movement of the extrusion head 45 drives the clamping rod 47 to move downward. The clamping rod 47 engages with the inside of the clamping groove 48, thus connecting the support plate 41 and the stabilizing sleeve 49 into one unit. The stabilizing sleeve 49 is fixed to the frame 1 by bolts. Therefore, the support plate 41 is more stable after being supported, so that the support plate 41 will not shake during use. In turn, the hydraulic rod 410 connected to the support plate 41 will not shake, increasing the service life of the hydraulic rod 410. When it is necessary to remove the tape from the tension roller 21, the hydraulic rod 410 retracts and drives the support plate 41 to rotate.

[0043] The cutting mechanism 5 includes a first movable plate 51 mounted on the frame 1, a second movable plate 52 mounted on the first movable plate 51, and a first motor 53 mounted on the first movable plate 51. The output end of the first motor 53 drives the second movable plate 52 to move via a thread. A second motor 54 is mounted on the left support 12, and the second motor 54 drives the first movable plate 51 to move via a lead screw. A third motor 55 is mounted on the second movable plate 52, and a cutting blade 56 is mounted on the output end of the third motor 55. The cutting blade 56 is used to cut tape rolls. A first helical gear 57 is mounted on the third motor 55, and a second helical gear 58 is mounted below the first helical gear 57. The second helical gear 58 is equipped with blades 510. A dust collection trough 511 is mounted on the second movable plate 52, and a dust collection hood 59 is mounted on the outlet of the dust collection trough 511.

[0044] The third motor 55 drives the cutting blade 56 to cut, simultaneously driving the blades 510 to rotate. The rotation of the blades 510 generates negative pressure suction, causing dust generated by the cutting blade 56 to enter the dust collection hood 59 through the dust collection groove 511. The dust primarily originates from the inner lining of the tape roll; therefore, it is necessary to collect the dust while cutting the tape roll to achieve a dust-proof effect and prevent dust pollution from the cutting blade 56 during the cutting process.

[0045] The locking mechanism 3 includes a first pressing block 33 disposed inside the left support 12. The first pressing block 33 is used to press the end of the inner rod 25. A push rod 32 is rotatably disposed on the first pressing block 33. A locking rod 31 is disposed on the push rod 32. A clearance groove 34 is provided on the left support 12. A locking groove 35 is provided on one side of the clearance groove 34. The locking rod 31 enters from the clearance groove 34 and rotates into the upper part of the locking groove 35.

[0046] When it is necessary to move the inner rod 25, the locking rod 31 can be pushed first to move the push rod 32. The push rod 32 then moves the first pressing block 33, which presses against the end of the inner rod 25, causing the inner rod 25 to move inside the tensioning roller 21. When the inner rod 25 reaches its maximum stroke, the tensioning mechanism 2 just tightens both ends of the tape roll. Rotating the locking rod 31 causes it to move from the relief groove 34 into the locking groove 35, thereby locking the longitudinal movement of the inner rod 25. Preferably, a servo motor can be installed on the locking rod 31 to drive its movement and locking.

[0047] In use, the hydraulic rod 410 first drives the support plate 41 to flip, so that the tape roll is wrapped around the tension roller 21. One end of the tension roller 21 is rotatably mounted on the left support 12. The actuating rod 231 is moved according to the length of the tape roll. The actuating rod 231 drives the first clamping plate 234 to move. At this time, the actuating rod 231 is squeezed by the limiting block 236, and the actuating rod 231 will move towards the outside of the tension roller 21. When the end of the actuating rod 231 slides past the limiting block 236, the second elastic element 232 pushes the actuating rod 231 into one side of the limiting block 236. At this time, the limiting block 236 will restrict the reverse movement of the actuating rod 231, thereby achieving the limiting. When it is necessary to move the actuating rod 231 to drive the first clamping plate 234 to move in the opposite direction, the actuating rod 231 is pulled outward, so that the actuating rod 231... The end of the tape roll does not contact the limiting block 236; the position of the second clamping plate 2310 at the second opening 2313 is adjusted by moving the first clamping plate 234 to drive the second clamping plate 2310 to move, so that the second clamping plate 2310 can move inside the tensioning roller 21 and move to the end of the corresponding tape roll; the locking rod 31 can be pushed to drive the push rod 32 to move, the push rod 32 drives the first extrusion block 33 to move, the first extrusion block 33 will press on the end of the inner rod 25, so that the inner rod 25 moves inside the tensioning roller 21. When the inner rod 25 moves to the maximum stroke, the tensioning mechanism 2 just tightens both ends of the tape roll; the locking rod 31 is rotated, and the locking rod 31 will enter the interior of the locking groove 35 from the relief groove 34, thereby locking the longitudinal movement of the inner rod 25. When the inner rod 25 moves, it drives the extrusion groove 26 to move. When the extrusion groove 26 moves, it presses against the end of the top rod 222. The movement of the top rod 222 drives the tensioning block 221 to move. The tensioning block 221 moves toward the outside of the tensioning roller 21. A tape roll is sleeved on the tensioning roller 21. The movement of the tensioning block 221 tightens the tape roll. When the extrusion groove 26 moves with the inner rod 25 to the end of the top rod 222, the top rod 222 resets under the action of the first elastic element 223. At this time, the tensioning block 221 is housed inside the first rod groove 225. At the same time, the inner rod 25 moves, which drives the second top block 2312 to move. The second top block 2312 moves to the end of the first top block 2311 and presses the first top block 2311. The first top block 2311 moves toward the outside of the tension roller 21. Since the guide plate 239 provided at the end of the second clamping plate 2310 will move inside the inner cavity 238, the second clamping plate 2310 is pressed on the inner wall of the tape roll, thereby tightening the other end of the tape roll, thus achieving the positioning of the tape roll.When the inner rod 25 moves, it drives the limiting wheel 241 to move synchronously. The limiting wheel 241 can smoothly press the first guide rod 42 downward. When the first guide rod 42 moves downward inside the guide groove, it presses the bent rod 43. The bent rod 43 moves inside the guide groove. Since the connection between the bent rod 43 and the first guide rod 42 and the second guide rod 44 is movable, under the limiting action of the guide groove, the first guide rod 42 pushes the second guide rod 44 to move through the bent rod 43. The second guide rod 44 moves and presses against the extrusion head 45, thus extruding... The head 45 moves, causing the locking rod 47 to move downwards. The locking rod 47 engages with the slot 48, connecting the support plate 41 and the stabilizing sleeve 49 as a single unit. The stabilizing sleeve 49 is fixed to the frame 1 with bolts, thus making the support plate 41 more stable after support, preventing it from shaking during use. This, in turn, prevents the hydraulic rod 410 connected to the support plate 41 from shaking, increasing the service life of the hydraulic rod 410. When the tape roll on the tension roller 21 needs to be removed, the hydraulic rod 410 retracts, causing the support plate 41 to rotate. The third motor 55 is started, and its rotation drives the cutting blade 56 to cut while simultaneously driving the blades 510 to rotate. The rotation of the blades 510 generates negative pressure suction, and the dust generated by the cutting blade 56 during the cutting process enters the dust collection hood 59 through the dust collection groove 511. The dust mainly comes from the inner lining of the tape roll, so it is necessary to collect the dust while cutting the tape roll to achieve a dustproof effect and prevent dust pollution from the cutting blade 56 during the cutting process. After cutting, simply remove the cut tape from the tension roller 21.
