Technical Field
[0001] This utility model belongs to the field of label paper production technology, specifically an unwinding device for label paper production. Background Technology
[0002] In the production process of label paper, in order to release the roll of label paper smoothly and make the feeding process more continuous and stable, an unwinding device is often used to assist in the release of the label paper, thereby making the unwinding process of the label paper more stable.
[0003] Chinese Patent Publication No. CN219885270U discloses a novel label paper unwinding mechanism, including an unwinding assembly. The unwinding assembly includes a base plate, a support, and an unwinding roller wound with label paper. Cylinders are connected to both sides of the support, and rubber blocks are connected to the output ends of the cylinders. The rubber blocks are located below the unwinding roller. A detection mechanism includes a U-shaped frame connected to the outside of the support. Springs are connected to both sides of the top of the U-shaped frame, and tension sensors are connected to the tops of the springs. This invention uses tension sensors to detect the tension on the pull rod, so that when the label paper is not taut, the rubber blocks rise to prevent the unwinding roller from rotating, ensuring tension when the label paper is pulled out. Compared with existing technologies, this device can keep the label paper continuously taut, making it easier for operators to use.
[0004] The aforementioned unwinding device inevitably needs to remind external staff when the label paper unwinding is nearing completion. When staff are simultaneously monitoring several machines, it is difficult to detect in time that the unwinding is about to end, resulting in slower subsequent supply of label paper during processing and reduced work efficiency. Therefore, an unwinding device for label paper production is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes an unwinding device for label paper production.

[0024] Specific implementation examples are given below.
[0025] like Figure 1-4 As shown, an unwinding device for label paper production includes a processing base 1; an output motor 11 is installed on one side of the processing base 1; a release cylinder 12 is installed on the inner side of the processing base 1 via a bolt and nut assembly; a turntable 13 is rotatably connected to one side wall of the processing base 1; the turntable 13 and the release cylinder 12 are interconnected via a bolt and nut assembly; multiple sets of extrusion columns 14 are fixedly connected to the outer side wall of the turntable 13; a first fixed base 15 is installed on both sides of the bottom of the processing base 1; a spring column 16 is provided on the top of the first fixed base 15; a second fixed base 17 is fixedly connected to the top of the spring column 16; a first rotating column 18 is rotatably connected to the inner side of the second fixed base 17; a storage cylinder 19 is fixedly connected to one side of the second fixed base 17; a rattle plate 110 is installed inside the storage cylinder 19; a fixed ring 111 is fixedly connected to the inner side of the storage cylinder 19 away from the rattle plate 110; a striking column 112 is slidably connected to the inner side of the fixed ring 111; the striking column 112... A return spring 113 is fixedly connected to one end away from the fixed ring 111; the return spring 113 is connected to the side wall of the fixed ring 111; during operation, the operator installs the release tube 12 for winding the label paper inside the processing seat 1, so that the output motor 11, the release tube 12 and the turntable 13 are connected to each other; and multiple sets of spring columns 16 can push the second fixed seat 17 and the first rotating column 18 to move upward, so that the outer wall of the first rotating column 18 is in contact with the side wall of the label paper; when the thickness of the label paper on the release tube 12 gradually decreases to a certain thickness, the rotating turntable 13 can drive multiple sets of extrusion columns 14 to intermittently extrude the end of the striking column 112, and the return spring 113 resets the striking column 112, which can achieve the effect of striking the sounding plate 110 and emit a warning sound for the operator. The overall device reduces the occurrence of reduced work efficiency due to slow subsequent supply of label paper; the overall device improves the stability of label paper processing.
[0026] Furthermore, such as Figure 3As shown, the side wall of the extrusion column 14 has a groove 2; a slider 21 is slidably connected to the inside of the groove 2; a rotating wheel 22 is rotatably connected to the end of the slider 21; a threaded rotating column 23 is rotatably connected to the side wall of the extrusion column 14; a limiting block 25 is fixedly connected to the side wall of the extrusion column 14; the limiting block 25 is sleeved on the outside of the threaded push column 24; the threaded push column 24 and the threaded rotating column 23 are threadedly connected; during operation, when it is necessary to adjust the warning thickness, the operator operates the threaded rotating column 23 to rotate, so that the threaded push column 24 moves to the inside of the groove 2 through the limiting block 25, and the end of the threaded push column 24 presses against the slider 21, thereby pushing the slider 21 to move outward inside the groove 2; the whole device, by pre-pressing the striking column 112, can make the warning thickness of the label paper more in line with the working habits of the operator, thereby improving work efficiency.
[0027] Furthermore, such as Figure 2-3 As shown, a fixing plate 3 is fixedly connected to both sides of the top of the processing seat 1; an exhaust pipe 31 is fixedly connected to the top of the fixing plate 3; a rotating column 32 is fixedly connected to the side wall of the turntable 13; a transmission belt 33 is rotatably connected to the outer side wall of the rotating column 32; a rotating column 34 is rotatably connected to one end of the exhaust pipe 31; the outer side wall of the rotating column 34 is in contact with the inner side wall of the transmission belt 33; during operation, as the turntable 13 rotates, the transmission belt 33 can be driven to rotate by the rotating column 32, thereby causing the rotating column 34 to blow external air directly onto the label paper through the exhaust pipe 31, causing the dust attached to the surface of the label paper to fall off, thereby improving the cleanliness of the label paper surface.
[0028] Furthermore, such as Figure 2 As shown, a connecting plate 4 is fixedly connected to the bottom of the rotating column 18; a connecting plate 41 is fixedly connected to the bottom of the connecting plate 4; during operation, the operator can step on the connecting plate 41 and move the fixed seat 17 and the rotating column 18 downwards through the connecting plate 4. At this time, the operator can easily disassemble the release cylinder 12, thereby improving the ease of processing the label paper.
[0029] Furthermore, such as Figure 3 As shown, a fixing plate 2 5 is fixedly connected to the top of the processing seat 1; a rotating column 4 51 is rotatably connected to the end of the fixing plate 2 5; the outer side wall of the rotating column 4 51 is in contact with the inner side wall of the transmission belt 33; during operation, the fixing plate 2 5 and the rotating column 4 51 cooperate with each other to support the middle part of the transmission belt 33, thereby improving the stability of the wheel 22 during long-term operation and reducing the possibility of the transmission belt 33 sagging in the middle during long-term operation.
[0030] Furthermore, such as Figure 4As shown, a rotating bead 6 is rotatably connected to the end of the striking column 112. During operation, before the rotating wheel 22 presses the striking column 112, the rotating bead 6 first contacts the rotating wheel 22. The rotating bead 6 can effectively reduce the wear at the end of the striking column 112, thereby improving the stability of the striking column 112 during long-term operation.
[0031] Furthermore, such as Figure 4 As shown, the outer wall of the storage tube 19 has multiple sets of expansion slots 7; during operation, the expansion slots 7 can transmit the sound generated by the rattle plate 110 inside the storage tube 19 to the outside, thereby improving the warning effect on the staff.
[0032] Working principle: During operation, the operator installs the release cylinder 12 for winding label paper inside the processing base 1, connecting the output motor 11, the release cylinder 12, and the turntable 13. Multiple sets of spring columns 16 push the fixed base 17 and the rotating column 18 upwards, causing the outer wall of the rotating column 18 to fit against the side wall of the label paper. When the thickness of the label paper on the release cylinder 12 gradually decreases to a certain level, the rotating turntable 13 drives multiple sets of extrusion columns 14 to intermittently extrude pressure onto the end of the striking column 112. The return spring 113 resets the striking column 112, thus restoring the sounding disc 1. The device provides a striking effect and emits a warning sound for the worker. This reduces the likelihood of decreased work efficiency due to slow label paper supply. The device also improves the stability of label paper processing. When the warning thickness needs adjustment, the worker operates the threaded rotating column 23, causing the threaded push column 24 to move inwards through the limiting block 25 into the slide groove 2. The end of the threaded push column 24 presses against the slider 21, pushing the slider 21 outwards from the inside of the slide groove 2. By pre-pressing the striking column 112, the device ensures the label paper warning thickness better matches the work requirements. This improves work efficiency by influencing the work habits of the staff. During the rotation of the turntable 13, the drive belt 33 can be rotated via the rotating column 2 32, causing the rotating column 34 to blow external air directly onto the label paper through the exhaust pipe 31, causing dust adhering to the label paper surface to fall off, thus improving the cleanliness of the label paper surface. The staff can use the foot pedal connecting plate 2 41 to move the fixed base 2 17 and the rotating column 1 18 downwards via the connecting plate 1 4. At this time, the staff can easily disassemble the release cylinder 12, thus improving the ease of label paper processing. The fixed plate... The second 5 and the fourth 51 work together to support the middle of the transmission belt 33, thereby improving the stability of the pulley 22 during long-term operation and reducing the possibility of the transmission belt 33 sagging in the middle during long-term operation. Before the pulley 22 presses against the striking post 112, the rotating ball 6 first contacts the pulley 22. The rotating ball 6 can effectively reduce the wear at the end of the striking post 112, thereby improving the stability of the striking post 112 during long-term operation. The expansion slot 7 can transmit the sound generated by the rattle plate 110 inside the storage cylinder 19 to the outside, thereby improving the warning effect on the staff.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
