[0026] The preferred technical solution in this embodiment is as follows Figure 1 and Figure 2 As shown in , the labeling assembly includes a labeling box 8 rotatably arranged on the slider 4, and a second locking portion 9 is arranged between the labeling box 8 and the slider 4. The labeling box 8 can be freely rotated on the slider 4 to adjust the angle and then locked using the second locking portion 9. The labeling box 8 is provided with an opening and closing door. Figure 3 As shown in , the labeling box 8 is provided with an unwinding roller 10 and a driving roller 11, and a driving mechanism for driving the driving roller 11 to rotate. The bottom of the labeling box 8 is provided with an inverted triangle labeling head 12, and the labeling head 12 is provided with a through slot with upper and lower openings. The through slot is provided with a guide block 13 of the same inverted triangle. The triangles of the guide block 13 are all chamfered, and a thin rotating shaft 14 is provided at the lower opening of the through slot. Figure 3 As shown in the figure, the unwinding roller 10 is used to fix the label roll sleeve 15, and the driving roller 11 is used to fix the paper roll sleeve 16, wherein one end of the label tape 17 on the label roll sleeve 15 penetrates into the labeling head 12, and then passes through the thin rotating shaft 14 and then passes out from the labeling head 12 and is connected to the paper roll sleeve 16. During this period, the label 43 on the label tape 17 is separated from the paper tape 18 under the influence of the thin rotating shaft 14. At this time, the product on the conveyor belt will contact one end of the label 43 and take away the label 43 when passing by. After the label is coated with the labeling component 6, the label 43 will be completely attached to the product.

[0027] The preferred technical solution in this embodiment is to facilitate the disassembly of the label roll sleeve 15 and the paper roll sleeve 16. Figure 4As shown in the figure, the unwinding roller 10 and the driving roller 11 both include a roller body 19, a coaxial center hole 20 with an opening at the top is arranged in the roller body 19, a plurality of extension grooves 21 connected to the center hole 20 are arranged in an axially rotating array on the outer wall of the roller body 19, a top block 22 is slidably arranged in each of the extension grooves 21, a first spring 23 is arranged between each of the top blocks 22 and the extension groove 21, a protrusion 24 is arranged on the inner side of each of the top blocks 22, a top column 25 is slidably arranged in the center hole 20, a plurality of layers of ejection steps 26 corresponding to the protrusions 24 are arranged on the top column 25, and the bottom of each of the ejection steps 26 is chamfered. A second spring 27 is provided between the top column 25 and the bottom of the center hole 20, and a thread is provided on the top of the center hole 20 and a screw cover 42 is screwed thereon; the height of the top column 25 in the center hole 20 is adjusted up and down by loosening and tightening the screw cover 42 in cooperation with the elastic force of the second spring 27; during this period, when the ejection step 26 is aligned with the protrusion 24 up and down, the ejection block 22 on the outer side of the top column 25 will extend out of the roller body 19, thereby tightening the roll sleeve (including the label roll sleeve 15 and the paper roll sleeve 16) on the roller body 19; when the ejection step 26 is staggered with the protrusion 24, the ejection block 22 is retracted into the roller body 19 by the elastic force of the first spring 23, thereby releasing the tightening state of the roll sleeve, and the roll sleeve can be directly pulled out in this state.

[0028] The preferred technical solution in this embodiment is to prevent the unwinding roller 10 and the driving roller 11 from idling after the driving mechanism stops, causing the label tape 17 to loosen and affect the normal use of the labeling machine. Figure 4 and Figure 5 As shown in , the labeling box 8 is provided with gears 28 fixedly connected to the unwinding roller 10 and the driving roller 11, and a slide groove 29 is provided on one side of each gear 28, and a toothed slider 30 is slidably provided in each of the slide grooves 29, and one end of each of the toothed sliders 30 is provided with a tooth that matches the gear 28 gear teeth, and a third spring 31 is provided between each of the slide grooves 29 and the toothed slider 30. Through the elastic support of the third spring 31, the toothed end of the toothed slider 30 is always engaged with the gear 28, so that the gear 28 is self-locked after lacking the rotational power; when the gear 28 recovers the rotational power, the rotational torque of the gear 28 is greater than the elastic force of the third spring 31, so that the toothed slider 30 rebounds.

[0029] The preferred technical solution in this embodiment is that, considering that the label widths of different products are different, if the elastic force of the third spring 31 is too large, the resistance of the tooth slider 30 to the rotation of the gear 28 will be too large, thereby breaking the label tape 17 and the paper tape 18. Figure 5As shown in the figure, a pressure block 32 is arranged between each of the third springs 31 and the slide slot 29, and a threaded countersunk hole 33 connected to a slide slot 29 is opened on the outer wall of the labeling box 8. An adjusting bolt 34 whose inner end abuts the pressure block 32 is arranged in each of the threaded countersunk holes 33. By loosening and tightening the adjusting bolt 34, the pressure block 32 in the slide slot 29 is used to compress the third spring 31. By adjusting the compression length of the spring, the elastic force of the third spring 31 is adjusted.

[0030] The preferred technical solution in this embodiment is as follows Figure 6 As shown in , the label covering member 6 is a rubber sheet, one end of which is connected to the labeling box 8 and has a spring embedded therein, and the other end of the rubber sheet is cut into a plurality of strips.

The rotating shaft 38 is driven to rotate by rotating the crank 40, so that the external thread end 39 at the bottom of the rotating shaft 38 is lifted up and down in the threaded hole 36, and the spline rod 37 is driven to rise and fall synchronously during the process, so as to achieve height adjustment.

[0032] In the preferred technical solution of this embodiment, in order to improve the smoothness of rotation, a bearing 41 is provided between the spline rod 37 and the rotating shaft 38 .

[0033] In the preferred technical solution of this embodiment, the first locking part 5 is a jacking bolt arranged on the slider 4, and a flat section matching the jacking bolt is arranged on the side of one of the transverse slide bars 3, and the inner end of the jacking bolt abuts against the flat section of the transverse slide bar 3, and the locking state of the slider 4 and the transverse slide bar 3 can be achieved by loosening and tightening the jacking bolt. The second locking part 9 is a hinged hole bolt and a matching nut, and the hinged hole bolt is used as a hinge axis, and the tightening, squeezing or loosening state between the two components is achieved by loosening and tightening the hinged hole bolt and the matching nut.
