Description

Technical Field

[0001] This utility model relates to the field of label paper processing and production technology, and in particular to a self-adhesive rewinding device. Background Technology

[0002] Self-adhesive rewinding devices are used to rewind self-adhesive materials and consist of rewinding and tension control mechanisms. Their working principle is that the material enters the rewinding mechanism after unwinding, guiding, and tension control. Tension control ensures rewinding quality during the process, and the machine stops when the set value is reached. Currently, most self-adhesive rewinding devices on the market have unstable tension control, which may lead to material tearing, loose rewinding, and misalignment of roll layers during rewinding. Furthermore, they are difficult to use with different roll cores, making replacement difficult, reducing work efficiency, wasting time, and increasing costs.

[0003] Chinese Patent Publication No. CN110921385 discloses a utility model of a self-adhesive label winding device. The device includes: a frame on which a rotating motor, a winding mechanism, a cutting blade, and a control mechanism are mounted; the winding mechanism includes: a rotating frame, winding rollers, a transverse support, and a thickness sensor; the rotating frame is driven and connected to the rotating motor; the winding rollers are respectively disposed at both ends of the rotating frame; the thickness sensor is disposed on the transverse support, and its upper surface contacts the self-adhesive label roll on the winding roller, for measuring the thickness of the self-adhesive label roll; the control mechanism is electrically connected to the thickness sensor and the rotating motor, for controlling the operation of the rotating motor based on the thickness information; when the upper surface of the thickness sensor and the upper surface of the transverse support are on the same horizontal plane, the cutting blade contacts and cuts the self-adhesive label tape. This invention reduces roller changing time and improves production efficiency.

[0004] Most devices cannot effectively prevent the roll from falling off during winding, which may lead to safety accidents. Some devices use fixed roll cores, requiring manual alignment of the slots or tightening with tools, resulting in long roll changes and poor compatibility between different roll cores. Secondly, changing the roll is complicated and inefficient. In addition, unstable tension control may cause labels to wrinkle, deform, or be overstretched, especially thin self-adhesive materials, which are prone to tearing due to excessive tension or loose winding and interlayer displacement due to insufficient tension, affecting the accuracy of subsequent labeling processes.

[0005] Therefore, we propose a self-adhesive rewinding device to solve the above problems. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Reference Figure 1-5A self-adhesive rewinding device includes a base 1 with a feeding tension control mechanism 2 installed on one side of the top. This mechanism controls the tension change of the self-adhesive during the rewinding process. Two support walls 14 are fixedly connected to adjacent sides of the top of the base 1. A drive motor 6 is bolted to one side of one of the support walls 14. The output end of the drive motor 6 is driven by a roller changing mechanism 10 via a coupling. A core 19 is sleeved on the outside of the roller changing mechanism 10 for quick replacement of the core 19. A top plate 5 is fixedly connected to the top of the two support walls 14. Two pressure mechanisms 7 are fixedly connected to one side of the bottom of the top plate 5, and two upper hydraulic pumps 16 are fixedly connected to the other side. The bottom end of each pressure mechanism 7 is fixedly connected to a top support roller 15. The top support roller 15 is rotatably connected to a pressure roller 8 via a rotating bearing. Through the two pressure mechanisms 7, the pressure roller 8 can receive sufficient pressure, which facilitates the secondary control of the self-adhesive tension in the later stage. The top support roller 15 passes through the pressure roller 8 and is fixedly connected to the bottom end of the pressure mechanism 7. The bottom ends of the two upper hydraulic pumps 16 are fixedly connected to blade pads 4. The top of the machine base 1 and located between the feeding tension control mechanism 2 and the roller changing mechanism 10 are fixedly connected to two lower hydraulic pumps 17. The top of the two lower hydraulic pumps 17 is fixedly connected to blades 3. The blade pads 4 and blades 3 are symmetrical in the longitudinal direction, which facilitates the cutting of self-adhesive. The roller changing mechanism 10 includes a housing 1001, fixing bolts 1009, and a button 1014. The housing 1001 has a first inner cavity 1012 and a second inner cavity 1013. A partition 1002 is fixedly connected between the first inner cavity 1012 and the second inner cavity 1013. A bracket 1008 is fixedly connected to one side of the partition 1002 by fixing bolts 1009. A longer bolt is used to stabilize the bracket 1008. A turntable 12 is fixedly connected to one end of the bracket 1008. The button 1014... One end of the support column 1003 passes through the housing 1001, and the other end passes through the partition 1002. A support column 1003 is fixedly connected to the support column 1003 by pressing a button 1014. A slider groove 1015 is provided on one side of the support column 1003, and a movable plate 1005 is installed inside the slider groove 1015. Part of the slider groove 1015 provides space for the movable plate 1005 to move. A rolling groove 13 is provided on the movable plate 1005, and a horizontal bearing is slidably connected to the rolling groove 13. The transverse support shaft 1004 passes through the movable plate 1005 and the support column 1003 respectively. A turntable 12 is fixedly connected to one side of the movable plate 1005 to reduce the pressure on the transverse support shaft 1004. Limiters 1010 are fixedly connected to both sides of the top of the movable plate 1005. The top of the limiter 1010 passes through the bracket 1008. The bracket 1008 has slots 1011 at both ends on one side. An upper support cylinder 1006 is installed inside the slot 1011. The upper support cylinder 1006 is fixedly connected to the bracket 1008. The length of the upper support cylinder 1006 is slightly lower than that of the slot 1011. A tension spring 1007 is installed on the upper support cylinder 1006. A lower support cylinder 1016 is installed at the bottom of the tension spring 1007. The longitudinal movement of the limiter 1010 is realized by the elastic change of the tension spring 1007. One side of the lower support cylinder 1016 is fixedly connected to the movable plate 1005, thereby realizing the displacement change of the movable plate 1005.

[0020] Furthermore, the feeding tension control mechanism 2 includes a base 201, an inner support column 202, an outer support column 203, a pressing mechanism 9, a long roller 206, a short roller 204, a lower support shaft 205, and an upper support shaft 207. The outer support column 203 is fixedly connected to the top of the base 201, and the inner support column 202 is embedded inside the outer support column 203. Both the outer support column 203 and the inner support column 202 have matching small holes and are fixed by the pressing mechanism 9. When the pressing mechanism 9 is pressed, the outermost end of the pressing mechanism 9 is slightly lower than the small hole on the outer side of the inner support column 202. This allows the inner support column 202 to move and be fixed longitudinally inside the outer support column 203. The top of each pair of inner support columns 202 is fixedly connected to an upper support shaft 207 and a lower support shaft 205, respectively. The upper support shaft 207 passes through the long roller 206 and is connected to the long roller 206 by a rotating bearing. The lower support shaft 205 passes through the short roller 204 and is connected to the short roller 204 by a rotating bearing. Through the cooperation of the long roller 206 and the short roller 204, the tension of the self-adhesive tape is controlled for the first time during winding.

[0021] Furthermore, the pressure mechanism 7 includes a base 701, a protective shell 702, a central cavity 703, a high-pressure bearing spring 704, and a pressure support leg 705. One end of the base 701 is fixedly connected to the top plate 5, and the other end is fixedly connected to the protective shell 702. The protective shell 702 has a central cavity 703 inside, and the high-pressure bearing spring 704 is installed inside the protective shell 702. The elastic force of the high-pressure bearing spring 704 provides sufficient pressure to the pressure mechanism 7, which facilitates the secondary control of the tension of the self-adhesive in the later stage. One end of the high-pressure bearing spring 704 is fixedly connected to the base 701, and the other end is fixedly connected to the pressure support leg 705. The pressure support leg 705 is fixedly installed at the bottom of the high-pressure bearing spring 704.

[0022] Furthermore, the pressing mechanism 9 includes a reset support column 901, a rigid housing 902, a reset spring 903, and an inner cavity 904. The reset support column 901 is fitted with a rigid housing 902 at both ends, which supports the inner support column 202. The rigid housing 902 has an inner cavity 904 inside, and the reset spring 903 is installed inside the inner cavity 904. The elastic force of the reset spring 903 enables the rigid housing 902 to move laterally.

[0023] Furthermore, a column 11 is installed at the bottom of the roller changing mechanism 10 near the button 1014. A stable base 18 is fixedly connected to the bottom of the column 11. The column 11 is not fixed to the base 1 and can be moved in the non-working state. The column 11 can support the roller changing mechanism 10 in operation, thereby stabilizing the roller changing mechanism 10 in operation. The blade 3 and the blade pad 4 are longitudinally symmetrically distributed, which facilitates the cutting of non-stick adhesive.

[0024] Furthermore, the front view of the limiter 1010 is L-shaped to reduce its weight, the side view of the blade pad 4 is inverted Y-shaped to protect the blade 3 from chipping, and the side view of the column 11 is Y-shaped to distribute the pressure and make the column 11 more stable.

[0025] In summary: The operator first presses button 1014 to lower the limiter 1010. Rotating the core 19 allows for easy removal of the wound adhesive tape and facilitates replacement with different cores 19. The operator then uses the pressing mechanism 9 to retract the rigid housing 902 into the inner support column 202, allowing the inner support column 202 to move up and down on the outer support column 203. Moving the inner support column 202 adjusts the short roller 204 to a suitable height. The material to be wound is placed above the short roller 204. The pressing mechanism 9 is then used again to adjust the height of the long roller 206, ensuring it is tightly fitted to the material. The pressure between the long roller 206 and the short roller 204 initially controls the tension of the material during winding, ensuring it adheres to the top of the core 19. The strong pressure spring 704 in the pressure mechanism 7 then presses the pressure roller 8 against the core 19. The tight fit secures the winding material to the core 19, and also controls the tension of the winding material. The drive motor 6 is started, and the output shaft of the drive motor 6 rotates the roller changing mechanism 10 through the linkage. Since the limiter 1010 passes through the housing 1001 and the core 19, it not only restricts the left and right displacement of the winding material, but also positions the core 19. When the winding material reaches the target thickness, the drive motor 6 is turned off, and the upper hydraulic pump 16 and the lower hydraulic pump 17 are started at the same time. The blade pad 4 and the blade 3 move towards each other, thereby cutting the winding material between the blade pad 4 and the blade 3. The operator presses the button 1014, rotates and takes out the wound material, replaces the core 19, and then starts the drive motor 6 again to wind it up again.
