[0031] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0032] Reference Figure 1 This utility model provides a fully automatic production equipment for zero-tension bandages, including a feeding and gluing mechanism 2, a tension control mechanism 3, a rewinding mechanism 4, a cutting mechanism 5, a paper core feeding mechanism 6, and a unloading mechanism 7. The raw material of the bandage is unwound through the feeding and gluing mechanism 2, which applies glue to the raw material to form an adhesive bandage and conveys it to the rewinding mechanism 4. During this process, the tension control mechanism 3 adjusts the tension of the adhesive bandage to keep the first section of the adhesive bandage entering the rewinding mechanism 4 in a zero-tension state. The paper core feeding mechanism 6 moves the paper core onto the rewinding shaft 42 of the rewinding mechanism 4, and the rewinding mechanism 4 rewinds the adhesive bandage onto the paper core. Then, the cutting mechanism 5 cuts the adhesive bandage after rewinding, and the unloading mechanism 7 removes the rewound paper core from the rewinding shaft 42 to obtain the finished product. As can be seen from the above, the equipment in this embodiment can coat the bandage with glue and rewind it into a finished product in one go, and the process is fully automated, solving the problems of wasted time and manpower during bandage turnover.

[0033] In this embodiment, refer to Figure 2 and Figure 3The feeding and gluing mechanism 2 includes a feeding bracket 20 and an unwinding assembly 21, a gluing assembly, a guide wheel assembly 24, and a power conveying roller assembly 25 mounted on the feeding bracket 20. The unwinding assembly 21 includes an unwinding shaft, on which the bandage raw material is unwound. The gluing assembly includes gluing heads 22. While the bandage is being unwound and conveyed, an even number of gluing heads 22 apply glue to the bandage to form an adhesive bandage. The start control of the gluing heads 22 is matched with the amount of glue applied and the feeding speed, and is fed back to the PLC by an encoder 26 for control. The power conveying roller assembly 25 includes multiple power conveying rollers 25, and the power conveying rollers 25 are non-adhesive rollers. When the multiple power conveying rollers 25 rotate, they provide traction to drive the conveying of the adhesive bandage. The guide wheel assembly 24 provides support and guidance for the conveying of the bandage.

[0034] Furthermore, the feeding and coating mechanism 2 also includes a cooling air assembly, which includes a cooling air nozzle 23. The cooling air nozzle 23 blows cold air onto the bandage to cool the adhesive surface of the bandage. Specifically, the guide wheel 24 assembly includes two horizontally arranged guide wheels 24. The bandage is conveyed horizontally between the two guide wheels 24. The coating head 22 and the cooling air nozzle 23 are located between the two guide wheels 24 to facilitate the coating and cooling processes.

[0035] In this embodiment, refer to Figure 4 The tension control mechanism 3 includes a tension bracket 30 and a linear guide rail 31, a tension limit sensor 34 and a distance sensor 35 mounted on the tension bracket 30. The linear guide rail 31 includes a slide rail and a slider 32. A tension adjustment shaft 33 is provided on the slider 32, and the adhesive bandage is located below the tension adjustment shaft 33.

[0036] When there is insufficient bandage, the distance sensor detects the distance to the bandage and sends a signal to the unwinding assembly 21 and the power conveying roller 25 assembly to accelerate the feeding speed. This ensures that the bandage remains suspended throughout the rewinding process, almost unaffected by external forces, achieving zero-tension rewinding. When the bandage cannot be wound up due to external force, it will tighten upwards, touching the tension adjusting shaft 33 and causing the slider 32 to move. This triggers the tension limit sensor, causing the rewinding machine to alarm and stop rewinding.

[0037] It is understood that zero tension in this utility model does not mean that the tension of the bandage is 0, but only that the bandage is in a suspended state.

[0038] In this embodiment, refer to Figures 5-7The rewinding mechanism 4 includes a rewinding bracket 40 and a turntable assembly, a rewinding assembly, and a sealing assembly mounted on the rewinding bracket 40. The turntable assembly includes a turntable 41 and a turntable drive for driving the turntable 41 to rotate. The turntable drive includes a turntable motor 48. Three rewinding shafts 42 are arranged around the turntable 41, and when the turntable 41 rotates, it rotates the rewinding shafts 42 to the loading position C, the rewinding position A, and the sealing unloading position B. The rewinding assembly includes a first rewinding drive and a second rewinding drive 43. The second rewinding drive 43 is used to drive the rewinding shaft 42 located at the rewinding position A to rotate. The sealing assembly includes a first sealing drive and a second sealing drive 44. The first sealing drive is used to press the adhesive bandage against the paper core on the rewinding shaft 42 at the rewinding position A, and the second sealing drive 44 is used to drive the rewinding shaft 42 located at the sealing unloading position B to rotate.

[0039] The first rewinding drive and the first sealing drive are both cylinders, labeled as pressing cylinder 45 and sealing cylinder 46 respectively. The second rewinding drive 43 and the second sealing drive 44 are both belt driven. Taking the second rewinding drive 43 as an example, the second rewinding drive 43 includes a rewinding motor 431, a driving pulley 432, a driven pulley 433, a rewinding double-sided synchronous belt 434, and a rewinding synchronous pulley 435. The rewinding double-sided synchronous belt 43... 4 is connected between the driving pulley 432 and the driven pulley 433. The driving pulley 432 is connected to the main shaft of the rewinding motor 431, and the rewinding synchronous pulley 435 is connected to the rewinding shaft 42. The rewinding synchronous pulley 435 meshes with the rewinding double-sided synchronous belt 434. Thus, when the rewinding motor 431 drives the driving pulley 432 to rotate, the rewinding double-sided synchronous belt 434 drives the rewinding synchronous pulley 435 to rotate, which in turn drives the rewinding shaft 42 to rotate, thus performing the rewinding operation.

[0040] In this embodiment, refer to Figure 8 The cutting mechanism 5 includes a cutting bracket 50, a scissor translation component, and a pneumatic scissor 52. The scissor translation component includes a front-to-back moving cylinder 521, which is mounted on the cutting bracket 50. The pneumatic scissor 52 is mounted on the output end of the front-to-back moving cylinder 521. When the front-to-back moving cylinder 521 extends or retracts, it drives the pneumatic scissor 52 to move closer to or further away from the turntable 41. The pneumatic scissor 52 is used to cut the adhesive tape located between the rewinding position A and the sealing and unloading position B.

[0041] In this embodiment, refer to Figure 9 and Figure 10The paper core feeding mechanism 6 includes a feeding bracket 60, a hopper 61, a vibrating conveying guide 66, a transfer groove 69, and a feeding pusher. An inclined guide plate is provided on one side of the hopper 61, and the vibrating conveying guide 66 is connected to the top outer side of the guide plate. A lifting plate is provided inside the hopper 61 and is slidably connected to the guide plate. When the lifting plate moves upward, it is used to lift the paper core and drop it into the vibrating conveying guide 66. The discharge end of the vibrating conveying guide 66 is connected to the inlet end of the transfer groove 69. The feeding pusher is used to push the paper core located at the discharge end of the transfer groove 69 to be sleeved on the rewinding shaft 42.

[0042] Furthermore, the guide plate includes a first guide plate 62 and a second guide plate 63, which are arranged in a stepped manner and have a gap between them. The lifting plate includes a first lifting plate 64 and a second lifting plate 65. The first lifting plate 64 is slidably connected to the side of the first guide plate 62 near the hopper 61, and the second lifting plate 65 is slidably connected between the first guide plate 62 and the second guide plate 63. A lifting cylinder 612 and a connecting plate 6 are provided at the bottom of the hopper 61. 13. The lifting cylinder 612 moves the first lifting plate 64 and the second lifting plate 65 up and down through the connecting plate 613. When the paper core in the hopper 61 rolls onto the first lifting plate 64, the first lifting plate 64 rises up and moves against the paper core. After the paper core passes the first guide plate 62, it will roll towards the second guide plate 63. When it rolls onto the second lifting plate 65, the second lifting plate 65 rises up and continues to move against the paper core. After the paper core passes the second guide plate 63, it will roll towards the vibrating conveying guide 66 and roll into the vibrating conveying guide 66.

[0043] Furthermore, the discharge end of the vibrating conveying guide 66 is provided with an air blowing port 67. The paper core that rolls into the vibrating conveying guide 66 moves to the discharge end of the vibrating conveying guide 66 under vibration, and then the air blowing port 67 blows the paper core into the transfer groove 69.

[0044] Furthermore, the feeding pusher includes a pusher cylinder 611 and a pusher block 610 connected to the output end of the pusher cylinder 611. The pusher cylinder 611 is coaxial with the rewinding shaft 42 located at the feeding position C, thereby pushing the paper core in the transfer groove 69 onto the rewinding shaft 42.

[0045] In a preferred embodiment, a guide channel adjusting block 68 is slidably connected to the discharge end of the vibrating conveying guide channel 66. Moving the guide channel adjusting block 68 can adjust the size of the discharge port of the vibrating conveying guide channel 66 to accommodate paper cores of different sizes.

[0046] In this embodiment, refer to Figure 11 and Figure 12The feeding mechanism 7 includes a paddle 71, a paddle cylinder 72, and a scraper cylinder 73. The paddle 71 is connected to the output end of the paddle cylinder 72, and the paddle cylinder 72 is connected to the output end of the scraper cylinder 73. The paddle cylinder 72 is used to drive the paddle 71 to move away from / near the rewinding shaft 42 located at the material sealing position, and the scraper cylinder 73 is used to drive the paddle 71 to move along the length direction of the rewinding shaft 42.

[0047] Furthermore, the feeding mechanism 7 also includes a guide rod 75 and a feeding cylinder 74. The guide rod 75 is connected to the output end of the feeding cylinder 74. The feeding cylinder 74 is used to drive the guide rod 75 to rotate. When the guide rod 75 rotates to a horizontal state, it is coaxial with the rewinding shaft 42. When the scraper cylinder 73 drives the paddle 71 to move, it can push the rewound paper core with adhesive tape onto the guide rod 75. The diameter of the guide rod 75 is smaller than the inner diameter of the paper core so that the paper core can fall off and be fed.

[0048] It is understood that the rewinding action in this embodiment is as follows:

[0049] 1. While the unwinding assembly 21 and the power conveying roller 25 assembly pull and unwind the bandage raw material, the gluing head 22 applies glue to it. After the gluing is completed, the cold air blower 23 blows cold air to cool the glued surface.

[0050] 2. The paper core feeding mechanism 6 uses the lifting action of the lifting plate to send the paper core in the hopper 61 to the vibrating conveyor guide 66. As the vibrating conveyor guide 66 vibrates, the paper core is sent to the end of the vibrating conveyor guide 66. The air blowing port 67 of the vibrating conveyor guide 66 blows the paper core to the transfer groove 69. Then, the pushing cylinder pushes the paper core into the rewinding shaft 42. A plunger is installed on the rewinding shaft 42, so the paper core is fixed on the rewinding shaft 42.

[0051] 3. The turntable 41 rotates, causing the rewinding shaft 42 with the paper core to rotate 120 degrees clockwise from the feeding position C to the rewinding position A. The forward and backward moving cylinder 521 drives the pneumatic scissors 52 to move forward, cutting the bandage. Then the forward and backward moving cylinder 521 retracts, and at this time, the rewinding synchronous wheel 435 at the rear end of the rewinding shaft 42 meshes with the rewinding double-sided synchronous belt 434. The rewinding double-sided synchronous belt 434 starts to rotate clockwise, simultaneously driving the rewinding shaft 42 to rotate counterclockwise. The pressing cylinder 45 covers the material, and the tail of the bandage will adhere to the paper core as the rewinding shaft 42 rotates counterclockwise. When the tail of the paper core is completely adhered to the tail of the bandage, the rewinding double-sided synchronous belt 434 starts to rotate counterclockwise, and the rewinding shaft 42 drives the paper core to rotate clockwise for rewinding. After the rewound bandage reaches the specified length, the rewinding double-sided synchronous belt 434 stops rotating.

[0052] 4. After rewinding, the rewinding shaft 42 rotates 120 degrees clockwise from the rewinding position A to the sealing and unloading position B. At this time, the front and rear moving cylinder 521 drives the pneumatic scissors 52 to cut the bandage. The cutting sensor 47 senses and determines whether the bandage is cut. The sealing cylinder 46 covers the rewinding product. At this time, the sealing synchronous wheel at the rear end of the rewinding shaft 42 located at the sealing and unloading position B engages with the sealing double-sided synchronous belt. The sealing double-sided synchronous belt rotates counterclockwise, driving the rewinding shaft 42 to rotate clockwise. The bandage at the scissor tip is wound up and sealed as the rewinding shaft 42 rotates. At this time, the product is glued and rewound.

[0053] 5. The rewound product is on the rewinding shaft 42. The paddle cylinder 72 of the feeding mechanism 7 extends, driving the paddle 71 to be tangent to the rewinding shaft 42. Then, the scraping cylinder 73, along with the paddle 71, scrapes the rewound product onto the guide rod 75 of the feeding cylinder 74. Then, the feeding cylinder 74, along with the guide rod 75, rotates 90 degrees. The rewound product is fed out by gravity, completing the entire rewinding process of the equipment.

[0054] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
