All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Embodiment 1
[0024] See also Figure 1-Figure 5 The utility model provides a technical solution: a feeding and unwinding mechanism for label production, comprising a body 1, an inner wall of the body 1 is fixedly connected with a placing rack 2, the body 1 plays a fixed limiting role on the placing rack 2, so that the placing rack 2 will not deviate, the front end of the placing rack 2 is fixedly connected with two connecting rods 3, the front end of the connecting rod 3 is fixedly connected with a limiting block 6, the outside of the connecting rod 3 is slidably connected with a placing rack 4, the inside of the placing rack 4 is provided with two limiting grooves 12, the outside of the limiting block 6 is slidably connected to the inside of the limiting groove 12, the limiting groove 12 plays a limiting role on the internal limiting block 6, so that the placing rack 4 will not be separated from the outside of the connecting rod 3, the inside of the placing rack 2 and the placing rack 4 are both rotatably connected with a plurality of rollers 13, the edge of the label can slide on the outside of the roller 13, so that the roller 13 can guide the label without causing damage to the label.
[0025] When it is necessary to guide and correct the label, the label is placed inside the placement rack 1 2 and the placement rack 2 4, and the edge of the label is fit with the outside of the roller 13, so that the edge of the label can be fit with the "C"-shaped inner bend of the placement rack 1 2 and the placement rack 2 4, so that the label will not fall off from the inside of the placement rack 1 2 and the placement rack 2 4, and the transportation of the label is more stable.
[0026] Embodiment 2
[0027] On the basis of the first embodiment, in order to realize the correction of labels of different sizes, two installation grooves 7 are provided on the inner rear side of the placement frame 2 4, and the bottom end of the placement frame 2 4 is rotatably connected to the internal shaft 8, and the placement frame 2 4 limits the rotation shaft 8, so that the rotation shaft 8 can rotate stably, and the left and right sides of the outside of the rotation shaft 8 are fixedly connected to the pull rope 9, and the outside of the pull rope 9 is slidably connected to the inside of the installation groove 7, and the installation groove 7 limits the pull rope 9, so that the pull rope 9 will not deviate, and the outside of the pull rope 9 is provided with a spring 10, one end of the spring 10 is fixedly connected to the inner wall of the installation groove 7, and the end of the pull rope 9 away from the rotation shaft 8 A card block 11 is fixedly connected, and the other end of the spring 10 is fixedly connected to the end of the card block 11 close to the pull rope 9. The outside of the card block 11 is slidably connected to the inside of the installation groove 7. The installation groove 7 limits the internal card block 11, so that the card block 11 can stably squeeze the spring 10 to produce deformation. A plurality of card slots 5 are provided on the outside of the connecting rod 3. The spacing of the card slots 5 is adapted to the size of different labels. The card slots 5 on the left and right sides are symmetrically distributed. The outside of the card block 11 is engaged with the inside of the card slot 5, and the card block 11 matches the card slot 5. Since the size of the label is a standard size, the two card blocks 11 can limit the connecting rod 3 respectively.
[0028] When it is necessary to adjust the distance between the placement rack 1 2 and the placement rack 2 4, the rotating shaft 8 is rotated so that the rotating shaft 8 can wrap the pull rope 9, and then the pull rope 9 can pull the block 11 to move inward, so that the block 11 can squeeze the spring 10 to deform, and at the same time the block 11 can be disengaged from the inside of the front slot 5, and then the placement rack 2 4 is pulled forward, so that the placement rack 2 4 can slide on the outside of the connecting rod 3, and when the placement rack 2 4 moves to a suitable distance, the rotating shaft 8 is released, and the spring 10 is able to perform a reset movement, so that the spring 10 can push the block 11 to engage with the inside of the slot 5, so that the position of the placement rack 2 4 can be fixed.
[0029] Embodiment 3
[0030] On the basis of Example 2, in order to realize the correction of labels of different thicknesses, the interior of the placement rack 1 2 and the placement rack 2 4 are both slidably connected with a guide plate 14, and the placement rack 1 2 limits the internal guide plate 14. The interior of the guide plate 14 is slidably connected to the outside of the roller 13, so that the guide plate 14 and the roller 13 will not affect each other. The two guide plates 14 are fixedly connected to the separated sides with a slider 15, and the slider 15 limits the guide plate 14. The front and rear side sliders 15 are respectively slidably connected to the interior of the placement rack 1 2 and the placement rack 2 4, so that the slider 15 can slide smoothly. The internal thread of the middle slider 15 is connected to a threaded rod 16, and the two threaded rods 16 are respectively rotatably connected to the interior of the placement rack 1 2 and the placement rack 2 4, so that the threaded rod 16 can rotate stably.
[0031] When the height of the guide plate 14 needs to be adjusted, the threaded rod 16 is rotated so that the threaded rod 16 can drive the middle slider 15 to move downward, thereby driving the guide plate 14 to move downward. Since the placement rack 1 2 and the placement rack 2 4 limit the slider 15 and the guide plate 14, the guide plate 14 will not deviate during movement, thereby enabling the guide plate 14 to contact the surface of the label, making the label more stable during transportation.
[0032] In actual use, by adjusting the distance between placement rack 1 2 and placement rack 2 4, the labels can be transported from the inside of placement rack 1 2 and placement rack 2 4, so that the labels will not shift during transportation, and workers do not need to manually correct the labels, which reduces the labor intensity of the workers and does not affect the production progress of the labels, thereby ensuring that the production efficiency of the labels will not be affected, making the mechanism more economical to use.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
