Description

Technical Field

[0001] The utility model discloses a packaging label traction device, which relates to the field of label traction. Background Art

[0002] Labels with glue are commonly known as "self-adhesive labels". Wet wipes need to be labeled during the production and packaging process, and the movement of the label tape needs to be achieved through a label traction device.

[0003] The existing packaging label traction device refers to the patent document CN206155938U. The device proposed in the patent document has a simple structure and is relatively simple compared to traditional traction devices. It combines a traction roller with a pressure wheel, which greatly improves the traction force and ensures that the label tape is quickly released from the unwinding reel. It has the characteristics of reliable operation and high precision.

[0004] However, in actual use, it is found that the inner tube of the label tape roll has various sizes, and the above device cannot easily and quickly install label tape rolls of different sizes on the unwinding reel, which affects the rate of replacing the label tape roll and further affects the work efficiency of label traction.

The shaft end of the bidirectional threaded rod is fixedly connected with a handle.

[0010] Furthermore, the top end of the compression spring is fixedly connected to the inner top wall of the limiting groove, and the rotating shaft end of the second traction roller passes through the fixed plate and is fixedly connected to the output rotating shaft of the servo motor.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figure 1-Figure 4 This embodiment proposes a packaging label traction device, including a fixed plate 1, a reeling mechanism 2 and a traction mechanism 3 are provided on the front of the fixed plate 1, and the reeling mechanism 2 includes a reeling disc 201 rotatably sleeved on the inner wall of the fixed plate 1.

[0024] The inner wall of the unwinding disk 201 is rotatably sleeved with a bidirectional threaded rod 202, and two slide grooves 203 are provided on the front of the unwinding disk 201. The inner wall of each slide groove 203 is slidably connected to a slider 204 threadedly connected to the bidirectional threaded rod 202, and the outer surface of each slider 204 is fixedly connected to a positioning rod 205.

[0025] When the bidirectional threaded rod 202 rotates, the two sliders 204 can move respectively in the inner wall of the slide groove 203, and the two sliders 204 will move towards or away from each other. Since the positioning rod 205 is fixedly connected to the outer surface of the slider 204, the two positioning rods 205 can also move towards or away from each other.

[0026] In this way, label tape rolls of different sizes can be installed or removed by changing the positions of the two positioning rods 205. The two positioning rods 205 can be supported in the inner wall of the label tape roll to achieve rapid positioning of the label tape roll, making the replacement of the label tape roll more convenient, saving time and improving the traction efficiency of the label.

[0027] The inner walls of the two slide grooves 203 are fixedly connected to two guide rods 206, and the inner walls of the two sliders 204 are respectively slidably mounted on the outer surfaces of the four guide rods 206. By setting the guide rods 206, the sliders 204 can be more stable during movement, and the positions of the two positioning rods 205 can be adjusted conveniently, thereby facilitating the loading and unloading of label rolls of different sizes.

[0028] The shaft end of the bidirectional threaded rod 202 passes through the unwinding disk 201 and extends to the outside of the unwinding disk 201. The shaft end of the bidirectional threaded rod 202 is fixedly connected with a handle 207. By setting the handle 207, the contact area of ​​the shaft of the bidirectional threaded rod 202 can be increased, which facilitates the rotation of the bidirectional threaded rod 202 and further facilitates the adjustment of the distance between the two positioning rods 205.

[0029] The traction mechanism 3 includes a limiting groove 301 opened on the outer surface of the fixed plate 1, and the inner wall sliding sleeve of the limiting groove 301 is provided with a movable block 302, the top of the movable block 302 is fixedly connected to a compression spring 303, and the top of the compression spring 303 is fixedly connected to the inner top wall of the limiting groove 301.

[0030] By limiting the position of the compression spring 303 , the movable block 302 can be better limited so that the movable block 302 maintains a tendency of continuous downward movement.

[0031] The inner wall of the movable block 302 is rotatably connected with a first traction roller 304, and the inner wall of the fixed plate 1 is rotatably sleeved with a second traction roller 305. The first traction roller 304 and the second traction roller 305 are in contact with each other in an initial state.

[0032] A servo motor 306 is installed on the back of the fixed plate 1 , and the shaft end of the second traction roller 305 passes through the fixed plate 1 and is fixedly connected to the output shaft of the servo motor 306 . The servo motor 306 can drive the second traction roller 305 to rotate.

[0033] Since the types of labels are different, the thickness of the label tape is different. By setting the compression spring 303, the position of the first traction roller 304 is no longer fixed, so that the first traction roller 304 can move according to the thickness of the label tape, ensuring that the surfaces of the first traction roller 304 and the second traction roller 305 can contact the two side surfaces of the label tape, and use friction to stably pull the label tapes of different thicknesses.

[0034] The inner wall of the fixed plate 1 is rotatably sleeved with a first guide roller 4, a second guide roller 5 and a third guide roller 6, and the outer surfaces of the first guide roller 4, the second guide roller 5 and the third guide roller 6 are fixedly connected with a limiting plate 7, and the front side of each limiting plate 7 is in the same plane as the front side of the unwinding disk 201.

[0035] By providing the first guide roller 4, the second guide roller 5 and the third guide roller 6, the label tape can be conveniently guided, and by providing the limiting piece 7, the label tape can be limited and blocked to avoid excessive deviation of the label tape during transportation.

[0036] The inner wall of the fixed plate 1 is rotatably sleeved with a discharge roller 8, the discharge roller 8 and the unwinding disk 201 are respectively located on both sides of the front of the fixed plate 1, and the discharge roller 8 is located above the unwinding disk 201. By setting the discharge roller 8, the label tape can be output, which is convenient for subsequent labeling work.

[0037] In summary, the label tape roll is installed on the unwinding disk 201, and then the label tape is guided by the first guide roller 4, and then guided downward around the limit plate 7. The label tape guided upward by the limit plate 7 needs to continue to be pulled and transmitted between the first traction roller 304 and the second traction roller 305. After that, the label tape pulled and transported by the first traction roller 304 and the second traction roller 305 will be guided by the third guide roller 6, and finally bypass the discharge roller 8 for output and subsequent labeling work.

[0038] Working principle: first install the label tape reel on the unwinding disk 201. When installing the unwinding disk 201, put the inner wall of the label tape reel on the outer surface of the two positioning rods 205, and then turn the handle 207. When the handle 207 is rotated, the bidirectional threaded rod 202 will be driven to rotate. The rotation of the bidirectional threaded rod 202 can make the two sliders 204 move towards or away from each other. At this time, the handle 207 should be turned to make the two sliders 204 move away from each other on the inner walls of the two slide grooves 203. In this way, the two positioning rods 205 will move synchronously with the two sliders 204, so that the two positioning rods 205 can support and position the inner wall of the label tape reel. Then, the label tape will pass around the first guide roller 4 and the limit plate 7 in turn, and then pass through the first traction roller 304 and the second traction roller 305. Due to the different thicknesses of the label tapes, At the same time, in order to ensure that the label tape can be stably pulled and conveyed, a compression spring 303 is provided. The compression spring 303 can keep the movable block 302 and the first pulling roller 304 in a downward movement trend, so that the first pulling roller 304 and the second pulling roller 305 can respectively contact the upper and lower surfaces of the label tape when pulling and conveying the label tapes of different thicknesses, and then drive the servo motor 306 to work. When the servo motor 306 is working, it can drive the second pulling roller 305 to rotate, so that the first pulling roller 304 and the second pulling roller 305 can use friction to pull and convey the label tapes of different thicknesses more stably, and the label tapes conveyed by the first pulling roller 304 and the second pulling roller 305 can then bypass the third guide roller 6 and the discharge roller 8 in turn for output, which is convenient for subsequent labeling work.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
