Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape production, and in particular to an adhesive tape breakage detection device for adhesive tape production. Background Art

[0002] In the tape production industry, efficient and stable production processes are essential. In current tape production equipment, it is a common production process to split the original tape into multiple pieces and reel them through multiple paper tubes. With the continuous development of production technology, breakage detection equipment has been widely used in such equipment. It can timely sense whether the tape breaks during the production process. After detecting the breakage, it can quickly take measures such as stopping related operating parts and issuing alarms, which to a certain extent avoids more product quality problems and equipment failures caused by the continuous operation of the tape.

[0003] However, although the breakage detection equipment guarantees the controllability of the production process to a certain extent, there is still a significant problem in actual production that has not been effectively solved. When the tape breaks, due to the tension accumulated during the operation of the tape, the broken tape will rebound strongly. This rebound will not only cause direct damage to the surrounding equipment components, such as winding around the roller to cause the roller to deform, interfering with the transmission system to cause the belt to be misaligned or the chain to be de-toothed, but may also cause serious safety hazards and threaten the personal safety of operators, such as whipping and causing injuries. At the same time, the rebounding tape may also cause quality defects in subsequent products, such as scratches and wrinkles on the tape surface, and even broken fragments mixed into the finished product. Summary of the invention

[0008] The detection mechanism also includes a detection roller, which is arranged inside the main frame and close to the driving turntable.

[0009] The present invention is further configured such that a driving opening 1 is provided at one end of the outer wall of the driving turntable close to the driving slide rod, a driving bayonet 1 is provided inside the driving opening 1, one end of the driving slide rod extends into the driving opening 1 and the two are slidably connected, a bayonet surface 1 is provided on the outer wall of the driving slide rod located inside the driving opening 1, and a bayonet surface 2 is provided on the outer wall of the driving slide rod located inside the driving opening 2.

[0010] The present invention is further configured such that one end of the driving slide rod away from the driving turntable is fixedly connected to a docking joint, the outer wall of the docking joint is sleeved with a driving rod, a driving motor is fixedly connected to a position outside the driving cavity close to the driving rod, the output end of the driving motor passes through the interior of the driving cavity and is fixedly connected to the driving rod, and the outer wall of the docking joint is provided with a pushing spring with one end connected to the driving rod.

[0011] The present invention is further configured as follows: a fixed rod is fixedly connected to a position near the docking gear inside the driving cavity; a movable cavity is opened on a side of the fixed rod close to the main frame; a rack is slidably connected to the inside of the movable cavity; the rack is meshed with the docking gear; a connecting rod is hingedly connected to a position near the bottom of one side of the rack close to the main frame; one end of the connecting rod passes through the inside of the main frame; a splint is fixedly connected to one end of the connecting rod located inside the main frame; the splint is located below the detection roller.

[0012] The present invention is further configured such that the other end of the splint is fixedly connected to a connecting rod 2, the connecting rod 2 penetrates the main frame and extends into the interior of the driving chamber 2, a movable groove is provided on the outer wall of one end of the connecting rod 2 located inside the driving chamber 2, and a fixed frame 1 is hinged inside the movable groove, the bottom end of the fixed frame being fixedly connected to the inner wall of the driving chamber 2.

[0015] The beneficial effects of the adhesive tape breakage detection device for adhesive tape production of the present invention are as follows:

[0016] 1. In terms of detection and protection, the lifting cavity evenly distributed on the detection roller and the internal movable block, spring, electrode sheet and other components work together. During normal production, the tension of the tape causes the movable block to be squeezed into the lifting cavity and the electrode sheet to separate. Once the tape breaks, the spring quickly pushes the movable block out, the electrode sheet fits and is energized, triggering an alarm, which can promptly inform the operator of the fault. At the same time, the power-on signal activates the telescopic rod, pushes the drive slide rod to move, and cuts off the power supply of the drive turntable to the winding component, effectively preventing equipment damage and product quality problems caused by continuing to pull the broken tape.

[0017] 2. In terms of preventing the tape from rebounding, after the driving slide bar moves, the separation and docking of its card surface and the driving bayonet are cleverly designed. Card surface one separates from driving bayonet one to stop the power supply, and card surface two docks with driving bayonet two to drive the docking gear to rotate, thereby moving the rack upward, pulling one end of the splint upward, and clamping the tape tightly with the bottom end of the detection roller, which greatly avoids the strong rebound phenomenon caused by tension after the tape breaks, and reduces the risk of damage to peripheral equipment components, such as preventing the tape from wrapping around the roller shaft to cause it to deform, and avoiding interference with the transmission system to cause belt misalignment or chain de-toothing. At the same time, it also eliminates safety hazards to operators and prevents injuries caused by tape whipping.

[0018] 3. In terms of ensuring product quality, the sleeve ring is rotatably connected to the roller body, which reduces the friction of the tape when it passes through, avoiding scratches, wrinkles and other quality defects on the tape surface. Moreover, timely stopping of winding and clamping of broken tape effectively prevents broken fragments from mixing into the finished product, effectively ensuring product quality and improving production continuity and equipment service life.

[0039] The winding device 2 includes a winding assembly 21 rotatably connected to the inner wall of the main frame 1, and two ends of the winding assembly 21 extend to the inside of the second driving cavity 13 and the first driving cavity 11 respectively;

[0040] The winding device 2 also includes a detection mechanism 23, which includes a switching assembly 236. The switching assembly 236 includes a second fixing frame 2362 fixedly connected to the inner wall of the driving chamber 11, and the internal top of the second fixing frame 2362 is rotatably connected to a docking gear 23623. A driving port 23621 is provided on the side of the docking gear 23623 close to the detection roller 237, and a driving bayonet 23622 is provided inside the second driving port 23621. A driving slide bar 2364 is slidably connected inside the second driving port 23621. A driving turntable 2361 is rotatably connected at a position close to the driving slide bar 2364 inside the driving chamber 11. A connecting groove 23611 is provided on the circumferential outer wall of the driving turntable 2361. The connecting groove 23611 is connected to the winding assembly 21 through the transmission assembly 22 to drive the winding assembly 21 to rotate;

[0041] The detection mechanism 23 further includes a detection roller 237 , which is disposed inside the main frame 1 at a position close to the driving turntable 2361 .

[0042] By adopting the above technical scheme, the card surface 23641 cooperates with the driving card slot 23613 of the driving turntable 2361, and the winding component 21 is driven by the connecting groove 23611 and the transmission component 22. Under normal circumstances, the movable block 2373 extends out of the lifting cavity 23711 under the action of the spring 2374, and is pressed in when the tape is tensioned. When it breaks, the movable block 2373 pops out to make the electrode sheet fit and energize. The electrode sheet is energized to allow the telescopic rod 2372 to push the driving slide bar 2364, cut off the power of the driving turntable 2361, and stop the winding component 21. At the same time, the driving slide bar 2364 and the shift drive docking gear 23623 allow the rack 232 to pull the clamping plate 234 to clamp the tape.

[0043] The outer wall of the driving rotating disk 2361 near the end of the driving sliding rod 2364 is provided with a driving opening 23612, and a driving bayonet 23613 is provided inside the driving opening 23612. One end of the driving sliding rod 2364 extends into the driving opening 23612 and the two are slidably connected. The outer wall of the driving sliding rod 2364 located inside the driving opening 23612 is provided with a bayonet 23641, and the outer wall of the driving sliding rod 2364 located inside the driving opening 23621 is provided with a bayonet 236 42, one end of the driving slide rod 2364 away from the driving turntable 2361 is fixedly connected with a docking joint 23643, the outer wall of the docking joint 23643 is sleeved with the driving rod 2363, the outside of the driving chamber 11 near the driving rod 2363 is fixedly connected with a driving motor 12, the output end of the driving motor 12 passes through the inside of the driving chamber 11 and is fixedly connected with the driving rod 2363, and the outer wall of the docking joint 23643 is provided with a push spring 23644 with one end connected to the driving rod 2363.

[0044] By adopting the above technical solution, under normal conditions, the push spring 23644 pushes the driving slide rod 2364, so that the card surface 23641 fits with the driving card mouth 23613, and the driving motor 12 drives the driving slide rod 2364 through the driving rod 2363 and the docking joint 23643, thereby driving the driving turntable 2361 to rotate, and the driving turntable 2361 then drives the winding assembly 21 to wind up the tape through the connecting groove 23611 and the transmission assembly 22. When the tape passing through the detection roller 237 breaks, the movable block 2373 extends out of the lifting chamber 23711 under the action of the spring 1 2374, and the electrode sheet 2 23733 and the electrode sheet 1 23712 are fitted and energized, so that the telescopic rod 2372 is energized, and its output end extends out to push the driving slide bar 2364 to move. At this time, the card surface 1 23641 is separated from the driving card mouth 1 23613, and the driving slide bar 2364 stops supplying power to the driving turntable 2361.

[0045] A fixed rod 231 is fixedly connected to a position near the docking gear 23623 inside the driving chamber 11, and a movable chamber 2311 is opened on the side of the fixed rod 231 close to the main frame 1. A rack 232 is slidably connected inside the movable chamber 2311, and the rack 232 is meshed with the docking gear 23623. A connecting rod 1 233 is hinged near the bottom position of the rack 232 close to the main frame 1. One end of the connecting rod 1 233 passes through the inside of the main frame 1, and a splint 234 is fixedly connected to the end of the connecting rod 1 233 located inside the main frame 1. The splint 234 is located below the detection roller 237, and a connecting rod 2 235 is fixedly connected to the other end of the splint 234. The connecting rod 235 passes through the main frame 1 and extends to the inside of the driving chamber 2 13. A movable groove 2351 is opened on the outer wall of one end of the connecting rod 2 235 located inside the driving chamber 2 13, and a fixed frame 1 2352 with a bottom end fixedly connected to the inner wall of the driving chamber 2 13 is hinged inside the movable groove 2351.

[0046] By adopting the above technical scheme, the fixed rod 231 is fixed in the driving chamber 11 near the docking gear 23623, and its active chamber 2311 provides sliding space for the rack 232. During normal production, each component is in a relatively static or stable operating state, and the position of the rack 232 in the active chamber 2311 remains unchanged. The docking gear 23623 rotates to drive the rack 232 meshing with it to move up in the active chamber 2311. The rack 232 moves up and pulls the connecting rod 1 233 hinged thereto. The connecting rod 1 233 drives the splint 234 to move up near one end of the driving chamber 11, and the other end of the splint 234 is hinged to the fixed frame 1 2352 through the connecting rod 235. When one end of the splint 234 moves up, the connecting rod 235 rotates in the active groove 2351 relative to the fixed frame 1 2352 to ensure that the splint 234 can move smoothly. Finally, the splint 234 moves up and is tightly attached to the bottom end of the detection roller 237.

[0047] The detection roller 237 includes a roller body 2371 fixedly connected to the inner wall of the main frame 1, a telescopic rod 2372 is arranged inside the roller body 2371 at one end close to the driving turntable 2361, the output end of the telescopic rod 2372 passes through the main frame 1 and extends to the driving turntable 2361, a plurality of lifting cavities 23711 are evenly opened on the outer wall of the roller body 2371, a movable block 2373 is slidably connected inside the lifting cavity 23711, a spring 2374 with one end connected to the inner wall of the lifting cavity 23711 is arranged on the top of the movable block 2373, and the lifting cavity 23711 is provided with a plurality of lifting cavities 23711. An electrode sheet 1 23712 is arranged at the bottom of the inner side of 3711 near the movable block 2373, a mounting plate 23732 is arranged at a side of the movable block 2373 near the electrode sheet 1 23712 near the top, an electrode sheet 2 23733 is arranged at the bottom of the mounting plate 23732, a plurality of rollers 23731 are rotatably connected to the bottom of the movable block 2373, a rotating groove 23713 is provided on the circumferential outer wall of the roller body 2371 near the lifting chamber 23711, and a ring 2375 is rotatably connected inside the rotating groove 23713.

[0048] By adopting the above technical solution, the telescopic rod 2372 is set at one end of the roller body 2371 close to the driving turntable 2361, and its output end passes through the main frame 1 and extends to the driving turntable 2361. When the electrode sheet 1 23712 and the electrode sheet 2 23733 are in contact and energized, the output end of the telescopic rod 2372 extends out to push the driving slide bar 2364 to realize power switching. During normal production, the tension force of the tape winding squeezes the movable block 2373, causing it to overcome the elastic force of the spring 1 2374 and enter the lifting chamber 23711, and the electrode sheet 1 23712 is separated from the electrode sheet 2 23733. When the tape breaks, the movable block 2373 loses the tape pressure, and the spring 1 2374 quickly pushes the movable block 2373 out of the lifting chamber 23711, and the electrode sheet 2 23733 and the electrode sheet 1 23712 are fitted and energized. The device sounds an alarm, and the rotating ring 2375 connected in the rotating groove 23713 can reduce the friction of the tape when passing through the roller body 2371, thereby avoiding quality problems such as scratches and wrinkles on the tape.

[0049] The working principle and use process of the embodiment of the present invention are as follows:

[0050] In the normal state, the movable block 2373 will be pushed out of the lifting cavity 23711 by the spring 1 2374, and the output end of the telescopic rod 2372 passes through the main frame 1 and extends to the inside of the driving turntable 2361. The output end of the telescopic rod 2372 is slidably connected to the inner wall of the driving turntable 2361. In the normal state, the driving slide bar 2364 will be pushed by the pushing spring 23644 so that the card surface 1 23641 and the driving bayonet 1 23613 fit together. The driving bayonet 1 23613, the driving bayonet 2 23622, the card surface 1 23641, the card surface 2 23642, and the docking joint 23643 are all non-circular designs, and the end of the splint 234 close to the driving cavity 2 13 is higher than the other end.

[0051] The winding assembly 21 is used to wind up the tape. When the tape is wound up, it will pass through the detection mechanism 23. The ring 2375 is rotatably connected to the roller body 2371, which can reduce the friction of the tape when it passes through the roller body 2371. The tension force when the tape is wound up will squeeze the movable block 2373 into the lifting chamber 23711, thereby separating the electrode sheet 1 23712 from the electrode sheet 2 23733. However, the pushing of the spring 1 2374 will make the movable block 2373 close to the tape, and direct contact is avoided by the roller 23731 set at the bottom of the movable block 2373. At the same time, the rotation of the roller 23731 can reduce the friction with the tape, and the tape passing through the detection roller 237 will be wound up by the winding assembly 21.

[0052] When any one of the adhesive tapes breaks, the corresponding movable block 2373 will suddenly lose pressure, and the spring 1 2374 will react instantly to push the movable block 2373, thereby pushing the movable block 2373 out of the lifting chamber 23711. When the movable block 2373 moves, it will drive the electrode sheet 2 23733 and the electrode sheet 1 23712 to fit together. The fitting of the two will be energized, thereby causing the device to sound an alarm.

[0053] At the same time, the electrode sheet 23733 and the electrode sheet 1 23712 are fitted together to energize the telescopic rod 2372. When the telescopic rod 2372 is energized, the output end extends, thereby pushing the driving slide bar 2364 to move through the output end. The movement of the driving slide bar 2364 will separate the card surface 1 23641 from the driving card slot 1 23613. After separation, the driving slide bar 2364 will stop supplying power to the driving turntable 2361, so that the winding assembly 21 stops winding, which is used to prevent continued pulling. The tape, at the same time, as the driving slide rod 2364 moves, the card surface 23642 will be docked with the driving bayonet 23622. When the two are docked, the docking gear 23623 will be driven to rotate. The rotation of the docking gear 23623 will drive the rack 232 to move up in the active cavity 2311. The movement of the rack 232 will pull one end of the splint 234 to move up. When this end of the splint 234 moves up, it will be tightly attached to the bottom end of the detection roller 237, thereby clamping the tape.

[0054] In summary, compared with the prior art, the embodiments of the present invention have the following advantages:

[0055] Advantage 1: Efficient and accurate detection mechanism. The lifting chamber 23711, movable block 2373, spring 1 2374, electrode sheet 1 23712 and electrode sheet 2 23733 on the detection roller 237 cooperate with each other. During normal production, the tension of the tape presses the movable block 2373 into the lifting chamber 23711, and the electrode sheets are separated. Once the tape breaks, the spring 1 2374 quickly pushes the movable block 2373 out, and the electrode sheets are fitted and energized. Compared with traditional detection methods, the tape breakage can be detected more timely and accurately, thus gaining precious time for subsequent protective actions.

[0056] Advantage 2: Reliable power cut-off and rebound suppression. When the tape is detected to be broken, the electrode sheet is pressed together and energized to make the telescopic rod 2372 work, pushing the driving slide bar 2364 to move, and the card surface 1 23641 of the driving slide bar 2364 is separated from the driving bayonet 1 23613, stopping the power supply to the driving turntable 2361, and then stopping the winding assembly 21 from winding, effectively preventing continued pulling of the broken tape from causing damage to the equipment. At the same time, after the driving slide bar 2364 moves, the card surface 23642 is docked with the driving bayonet 23622, driving the docking gear 23623 to rotate, so that the rack 232 moves up, and one end of the splint 234 is pulled up to clamp the tape tightly with the bottom end of the detection roller 237, thereby avoiding the rebound of the tape after it breaks to a great extent. This is an effective protective measure that most equipment in the prior art does not have.

[0057] Advantage three: All-round product quality assurance. The ring 2375 is rotatably connected to the roller body 2371, which reduces the friction of the tape when it passes through and avoids quality defects such as scratches and wrinkles caused by friction. This is a front-end guarantee for product quality. Timely stopping of winding and clamping of broken tape effectively prevents broken fragments from mixing into the finished product, which comprehensively guarantees product quality from the intermediate and terminal links of the production process and improves the stability and reliability of product quality.

[0058] Advantage 4: Extend the service life of the equipment. By timely detecting the breakage of the tape and stopping the reeling, the broken tape is prevented from damaging the equipment components such as the roller and the transmission system, preventing the tape from wrapping around the roller and deforming it, and avoiding interference with the transmission system that causes belt misalignment or chain debonding. It effectively extends the overall service life of the equipment and reduces the equipment maintenance cost, which is difficult to achieve with the existing technology due to the lack of effective protection.

[0059] Advantage 5: It effectively prevents the rebound and whipping of the tape after it breaks, eliminates the safety hazard to the operator, and provides a safer working environment for the operator. This is a safety shortcoming in the prior art due to the inability to effectively control the rebound of the tape.
