Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please see Figures 1 to 3This utility model provides a technical solution: a label rolling device for label bags, including a conveyor belt 1. The surface of the conveyor belt 1 is treated with anti-static voltage scratches. A tension mechanism 2 is fixedly connected to the top right side of the conveyor belt 1. The tension mechanism 2 includes a vertical plate 21, which is used to initially guide the label strip and prevent edge burrs from cutting hands. A guide plate 4 is fixedly connected to the outer front side of the vertical plate 21. Two support columns 5 are fixedly connected to the outer front side of the vertical plate 21. Multiple limiting strips 6 are fixedly connected to the outside of the support columns 5. The grooves formed between adjacent limiting strips 6 limit the label strip. A rotating roller 7 is provided outside the limiting strip 6. The rotating roller 7 is a hollow cylindrical structure that can rotate synchronously with the movement of the label strip to reduce the resistance during the conveying of the label strip. The bottom of the vertical plate 21 is fixedly connected to the top right side of the conveyor belt 1. The vertical plate 21 is internally slidably connected to a sliding block 22. The sliding block 22 is externally fixedly connected to a connecting post 23. The other end of the connecting post 23 is fixedly connected to a perforated plate 24 with two holes on the outside for swinging in conjunction with a limiting post 26. The perforated plate 24 is externally slidably connected to the front side of the vertical plate 21. The internal groove of the perforated plate 24 is slidably connected to the outside of the two limiting posts 26. The upper external end of the perforated plate 24 is fixedly connected to an adjusting plate 25 for directly contacting the wrapping strip to change the wrapping angle and adjust the tension in real time, preventing scratches on the ink on the surface of the wrapping strip. The front external side of the vertical plate 21 is fixedly connected to two limiting posts 26, which restrict the movement of the tension mechanism 2 inside the perforated plate 24. The vertical plate 21 is internally fixedly connected to a fixing post 27 to support the rotation of the cylinder 291. The fixing post 27 is externally rotatably connected to a fixing block 28.

[0025] A drive assembly 29 is fixedly connected to the outside of the fixed block 28. The drive assembly 29 includes a cylinder 291. The cylinder 291 is fixedly connected to the outside of the fixed block 28. A telescopic column 292 is fixedly connected to the drive end of the cylinder 291. The cylinder 291 rotates under the drive of the cylinder 291. The telescopic column 292 is fixedly connected to the outside of the sliding block 22.

[0026] like Figure 1 and Figure 4 As shown, the tension mechanism 2 is externally fixedly connected to multiple guide posts 3. The guide posts 3 are used to guide the label strip from the unwinding roller 7 through each guide post 3 in a serpentine manner, and finally guide it to the take-up roller 7 to reduce vibration. Two support plates 8 are fixedly connected to the front of the tension mechanism 2 to support the spacing mechanism 9. The spacing mechanism 9 is fixedly connected to the adjacent side of the two support plates 8. The spacing mechanism 9 includes a collection box 91, which facilitates manual stacking and placement of label bags. The outer sides of the collection box 91 are fixedly connected to the adjacent side of the two support plates 8. A rectangular hole 92 is opened on the outer left side of the collection box 91 for the label bag to be fed out.

[0027] A power assembly 93 is fixedly connected to the inside right side of the vertical plate 21. The power assembly 93 includes a motor 931. The motor 931 is fixedly connected to the outside of the vertical plate 21. A rotating shaft 932 is fixedly connected to the drive end of the motor 931, which rotates under the drive of the motor 931. The rotating shaft 932 is rotatably connected to the outside of the vertical plate 21. The groove inside the vertical plate 21 is slidably connected to the outside of the connecting column 23. The rotating shaft 932 is fixedly connected to the outside of the eccentric wheel 94. The eccentric wheel 94 is fixedly connected to the outside of the power assembly 93. The label bags that are in contact with each other at the bottom are transported to the outside through the rectangular hole 92. Multiple rubber blocks 95 are fixedly connected to the outside of the eccentric wheel 94 to increase the friction between the eccentric wheel 94 and the label bags, which facilitates the transportation of the label bags. Correction plates 96 are fixedly connected to both sides of the top of the conveyor belt 1.

[0028] Working principle: First, the strip on the rotating roller 7 passes through multiple guide posts 3 and through the guide plate 4 and is placed on another rotating roller 7 for winding. During the winding process, the cylinder 291 is activated according to the tightness of the strip, so that the cylinder 291 drives the telescopic post 292 to push the sliding block 22 to move. Under the transmission of the sliding block 22, the connecting post 23 moves accordingly. Because the connecting post 23 is in the hole opened inside the vertical plate 21, the connecting post 23 slides in accordance with the opening of the hole and transmits the force to the perforated plate 24, so that the perforated plate 24 moves accordingly. Because the perforated plate 24 has an arc-shaped hole on the upper side and there is a limit post 26 in the hole, the perforated plate 24 rotates left and right under the restriction of the limit post 26, so that the adjusting plate 25 rotates accordingly, thereby changing the angle and adjusting the tension of the strip.

[0029] A label bag is placed in the collection box 91. Then, the motor 931 is started to drive the rotating shaft 932 to rotate. Under the drive of the rotating shaft 932, the eccentric wheel 94 rotates. The central axis of the eccentric wheel 94 is at the edge, so that the eccentric wheel 94 will indirectly contact the label bag in the collection box 91. Thus, the rubber block 95 on the contact edge of the eccentric wheel 94 contacts the label bag, and the label bag falls through the rectangular hole 92 under the action of force and onto the conveyor belt 1. Correction plates 96 are set on both sides of the conveyor belt 1 so that the label bag always stays in the center position under the transportation of the conveyor belt 1.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
