[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] As attached Figure 1 As shown, the utility model provides a vacuum adsorption device for label paper labeling, including a label removal drum and a label suction drum rotatably mounted on the top of a frame (not shown). The label removal drum is used to absorb the labels that have been glued and transfer them to the label suction drum. The label suction drum matches the material to be labeled.

[0032] Specifically, a second rotating shaft 13 and a third rotating shaft 15 are rotatably installed on the frame. The top of the second rotating shaft 13 is detachably connected to the first rotating shaft 9. The second seal 10 is sleeved at the connection and fixed by a second clamp 33. The mark taking drum is fixedly installed on the first rotating shaft 9; the top of the third rotating shaft 15 is detachably connected to the fourth rotating shaft 20. The third seal 19 is sleeved at the connection, and the mark suction drum is fixedly installed on the fourth rotating shaft 20.

[0033] Both the label suction drum and the label removal drum are hollow structures, and a second adsorption hole 28 is provided on the side wall of the label suction drum, and a first adsorption hole 22 is provided on the side wall of the label removal drum; the second rotating shaft 13, the third rotating shaft 15, the first rotating shaft 9, and the fourth rotating shaft 20 are all hollow tubular structures, and the second rotating shaft 13 is connected with the first rotating shaft 9 and the label removal drum in sequence, and the third rotating shaft 15 is connected with the fourth rotating shaft 20 and the label suction drum in sequence, and the second rotating shaft 13 and the third rotating shaft 15 are connected with the air inlet end of the fan through the air path, thereby realizing negative pressure in the label removal drum and the label suction drum, and completing the adsorption and transfer of the label paper.

[0034] As attached Figure 3 and attached Figure 5 As shown, the marking drum includes a first adsorption cylinder 1 with an open top, fixed to a fourth rotating shaft 20. The top of the fourth rotating shaft 20 passes through the first adsorption cylinder 1 and is then connected to a first end cap 4, which abuts the top of the first adsorption cylinder 1. The fourth rotating shaft 20 is also threadedly mounted with an end cap 3 for limiting the position of the first end cap 4. A first sealing member 2 is installed between the first end cap 4 and the end cap 3. This structure allows the first end cap 4 to be removed, allowing cleaning of the interior of the first adsorption cylinder 1.

[0035] A portion of the fourth rotating shaft 20 located inside the first adsorption cylinder 1 is provided with a plurality of first air holes 23 .

[0036] A first groove 24 is provided at the bottom of the fourth rotating shaft 20, and a first flange 25 matching the first groove 24 is provided at the top of the third rotating shaft 15. During installation, the first flange 25 is placed in the first groove 24 and fixed by bolts; the third sealing member 19 is sleeved at the connection and fixed by a first clamp 27.

[0037] The third rotating shaft 15 passes through a second sleeve 18 fixedly mounted on the frame and rotatably engages with the second sleeve 18 via a first bearing 26. After the third rotating shaft 15 passes through the frame, the first gear 14 is mounted. A second bearing seat 17, which rotatably engages with the third rotating shaft 15, is also fixedly mounted at the bottom of the frame. This sleeve and bearing seat design fully ensures the stability of the third rotating shaft 15.

[0038] The protruding teeth 16 on the first gear 14 mesh with the third gear on the drive motor (not shown).

[0039] The outer wall of the first suction cylinder 1 is provided with a first protruding ring and a first annular groove 35, spaced apart from each other. The first protruding ring is divided into a second curved portion 37 and a first curved portion 36 by two vertical third grooves 34. The aforementioned first suction hole 22 is located in the first curved portion 36. The two vertical third grooves 34 are located at opposite ends of the same diameter of the first suction cylinder 1. This arrangement allows the ends of the label paper to be located in the two third grooves 34, preventing glue from adhering to the label removal drum and facilitating the transfer of the label paper to the label absorption drum.

[0040] The structure of the suction drum is as shown in the attached Figure 4 and attached Figure 6 As shown, it includes a second adsorption cylinder 8 fixedly mounted on a first rotating shaft 9 and having an open top. A stud 6 is fixedly mounted on the top of the second adsorption cylinder 8. A second end cap 5 is sleeved on the stud 6 and abuts against the top of the second adsorption cylinder 8. The second end cap 5 is retained in place by a nut 7 mounted on the stud 6. This design allows the interior of the second adsorption cylinder 8 to be cleaned.

[0041] A second air hole 29 is provided in the portion of the first rotating shaft 9 located at the second adsorption cylinder 8 .

[0042] The second rotating shaft 13 passes through the first shaft sleeve 11 fixedly mounted on the frame and is rotatably engaged with the first shaft sleeve 11 via the second bearing 32. After passing through the frame, the second rotating shaft 13 is rotatably engaged with the first bearing seat 12 mounted at the bottom.

[0043] The outer wall of the second adsorption cylinder 8 is provided with spaced apart second protruding rings 38 and second annular grooves 39. The aforementioned plurality of second adsorption holes 28 are arranged in an annular array on the second protruding ring 38. The second protruding rings 38 correspond one-to-one with the first protruding rings, and the second annular grooves 39 correspond one-to-one with the first annular grooves 35.

[0044] Of course, the first bearing seat 12 and the second bearing seat 17 can also be installed in the frame in other ways. The top of the first adsorption cylinder 1 can also use a non-openable end cover instead of the existing openable structure. Similarly, the top of the second adsorption cylinder 8 can also use a non-openable end cover instead of the existing openable structure.

[0045] To facilitate the transfer of label paper from the label removal drum to the label absorption drum, and to facilitate the attachment of label paper from the label absorption drum to the material, the absorption module 6 also includes two paddle groups 21. Each paddle group 21 is equipped with two sets of arc-shaped paddles, which are located in the corresponding first annular groove 35 and second annular groove 39, respectively. When the label paper on the label removal drum rotates to the corresponding set of paddles, it is picked up by the corresponding paddles and approaches the label absorption drum along the arc of the paddles, where it is then smoothly adsorbed to the drum. As the label absorption drum rotates, the end of the label paper meets the other set of paddles again and is picked up. The label paper then approaches the material along the arc of the paddles. In other words, this paddle group 21 guides the transfer of the label paper.

[0046] As attached Figure 7As shown, the paddle assembly 21 includes a first paddle assembly and a second paddle assembly. The first paddle assembly includes a first connecting post 40. A plurality of arcuate first paddles 42 are fixedly mounted on the first connecting post 40 in a linear array along its length. The ends of the first paddles 42 are positioned within corresponding second annular grooves 39. A first stopper 41 is sleeved on the first connecting post 40 between two adjacent first paddles 42 to position the first paddles 42.

[0047] The second paddle assembly includes a second connecting post 47. A plurality of arcuate second paddles 48 are fixedly mounted on the second connecting post 47 in a linear array along its length. The ends of the second paddles 48 are positioned within corresponding first annular grooves 35. A second stopper 49 is sleeved on the second connecting post 47 between two adjacent second paddles 48 to position the second paddles 48.

[0048] The bottom of the first connecting column 40 is fixedly inserted in the first connecting sleeve 43, and of course it can also be connected by other methods such as threaded installation; the first connecting sleeve 43 is fixedly connected to the positioning ring 45 through the first support arm 44; the bottom of the second connecting column 47 is installed in the second connecting sleeve 46, and the installation method is the same as the connection method between the first connecting column 40 and the first connecting sleeve 43. The second connecting sleeve 46 is fixedly connected to the positioning ring 45 through the second support arm, and the positioning ring 45 is sleeved on the first shaft sleeve 11 and then fixed by a top screw or bolt.

[0049] The interior of the fourth rotating shaft 20 is sequentially arranged from top to bottom, with a first large-diameter section 50 and a first small-diameter section 51 interconnected. The first small-diameter section 51 is connected to the first groove 24, and the diameter of the first groove 24 is larger than that of the first small-diameter section 51. Due to the presence of the first small-diameter section 51, the airflow is accelerated in the first small-diameter section 51 during the fan suction, which facilitates the discharge of gas from the first adsorption cylinder 1 and helps stabilize the negative pressure. The aforementioned first air hole 23 is located in the first large-diameter section 50.

[0050] As shown, the interior of the first rotating shaft 9 is provided with a second large-diameter section 52 and a second small-diameter section 53, which are interconnected from top to bottom. The second small-diameter section 53 is connected to the second groove 30. The diameter of the second groove 30 is larger than that of the second small-diameter section 53. The principle of this design is the same as that of the fourth rotating shaft 20. The aforementioned second air hole 29 is provided in the second large-diameter section 52.

[0051] A second flange 631 matching the second groove 630 is fixed to the top of the second rotating shaft 13 .

[0052] During operation, the label suction drum is unpowered. The rotating material first drives the drum, and the fan generates negative pressure between the label removal drum and the label suction drum. The rotating material presses against the drum, driving the drum's rotation. One end of the label's back is coated with glue, and the label removal drum absorbs the back of the label. The glued end lies in the third groove 34. When the label on the label removal drum rotates to the corresponding set of paddles, it is picked up by the corresponding paddles and moves toward the label suction drum along the arc of the paddles. It is then smoothly attracted to the drum, which then absorbs the front of the label, flipping the label over. As the label suction drum rotates, the end of the label meets another set of paddles again and is picked up. The label then moves along the arc of the paddles toward the material.

[0053] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
