Technical Field

[0001] The invention relates to the technical field of self-adhesive label processing, in particular to a paper sheet laminating device based on the manufacture of self-adhesive labels. Background Art

[0002] Self-adhesive labels are a common form of label. The surface is covered with a layer of glue that is not easy to fall off, and can be easily pasted on objects. Self-adhesive labels have the characteristics of strong durability, good adhesion, not easy to be damaged, and not easy to fall off. They are widely used in product packaging, office stationery, logistics and transportation.

[0003] The flattening process of the self-adhesive label is to make the label flat and neat through the process steps of pressing, conveying, drying, and sorting to meet the needs of different application occasions, such as a three-dimensional self-adhesive label pressing device disclosed in a Chinese patent (Announcement No.: CN215852346U);

[0029] Two sets of support plates 2 4 are fixedly connected on both sides of the outer surface of the upper end of the operating table 1, away from the side of the support plate 1. A pressure roller 5 and a support roller are arranged between the two sets of support plates 2 4. One end of the self-adhesive label paper is passed through between the support roller and the pressure roller 5, and then fixed on the surface of the winding roller 2. The support roller is rotatably connected to the support plate 2 4, and the pressure roller 5 is located above the support roller.

[0030] A slide groove is provided at a position corresponding to the outer surface of the support plate 2 4 and the pressure roller 5, and a T-shaped column 8 is fixedly connected inside the slide groove. A spring 10 and a slider 11 are provided on the outer surface of the T-shaped column 8, and the slider 11 is slidably connected to the T-shaped column 8. The pressure roller 5 is rotatably connected to the two groups of sliders 11.

[0034] Embodiment 3: Figure 2 , Figure 3 and Figure 5 As shown, the difference between this embodiment and the embodiment 1 and the embodiment 2 is that a pressing mechanism 7 is connected between the cleaning mechanism 6 and the two sets of supporting plates 4, and the pressing mechanism 7 includes a connecting plate 71 fixedly connected to the outer surface of one side of the cleaning plate 63, and the lower end outer surface of the connecting plate 71 is fixedly connected to the positions near both ends with convex strips 72;

[0035] A pressure plate 73 is provided below the connecting plate 71, and a rotation groove is provided on the outer surface of the upper end of the pressure plate 73 near both ends.

During the repeated movement of the cleaning plate 63, the convex strip 72 repeatedly fits and is misaligned with the corresponding rotation column 74. During the fit between the convex strip 72 and the rotation column 74, the pressure plate 73 drives the movable strip 75 to move downward.

[0036] The outer surface of the pressing plate 73 and the positions corresponding to the two groups of supporting plates 24 are fixedly connected with movable bars 75. The positions corresponding to the supporting plates 24 and the movable bars 75 are provided with mounting grooves 76, and the movable bars 75 penetrate into the interior of the mounting grooves 76 and are movably connected thereto. The interior of the mounting grooves 76 is provided with springs 27, and the two ends of the springs 27 are respectively fixedly connected to the mounting grooves 76 and the movable bars 75. When the convex strip 72 and the rotating column 74 are misaligned, the pressing plate 73 drives the pressing roller 93 to move upward under the action of the springs 27. A support plate 78 is fixedly connected to the position below the pressing plate 73 between the two groups of supporting plates 24, and the support plate 78 supports the self-adhesive label paper.

[0037] Embodiment 4: Figure 2-7 As shown, the difference between this embodiment and embodiment 1, embodiment 2, and embodiment 3 is that a plurality of groups of pressing components 9 are provided on the outer surface of the lower end of the pressing plate 73, each group of pressing components 9 includes two groups of fixing blocks 91, and the fixing blocks 91 are fixedly connected to the pressing plate 73, and one side outer surface of the two groups of fixing blocks 91 is rotatably connected with a rotating shaft;

[0038] One end of the rotating shaft is fixedly connected with a rotating plate 92, and a pressing roller 93 is rotatably connected between the two sets of rotating plates 92. A torsion spring 94 is provided on the outer surface of the rotating shaft, and the two ends of the torsion spring 94 are respectively fixedly connected with the corresponding rotating plate 92 and the fixed block 91. The rotating plates 92 corresponding to the two adjacent sets of pressing rollers 93 are tilted in opposite directions in a natural state.

[0039] The pressing plate 73 drives the movable bar 75 to move downward, and the pressing rollers 93 move downward with the pressing plate 73. Under the joint action of the pressing plate 73 and the supporting plate 78, the two adjacent groups of pressing rollers 93 drive the rotating plate 92 to rotate in different directions. Under the action of the torsion spring 94, the pressing rollers 93 elastically roll and press the self-adhesive label paper in a direction perpendicular to the winding direction.

[0040] The outer surface of the lower end of the pressure plate 73 is fixedly connected to the limiting column 95 near the two ends, and the outer surface of the limiting column 95 is movably connected to the U-shaped frame 96, a fixing plate 99 is fixedly connected between the two groups of U-shaped frames 96, and the outer surface of the lower end of the fixing plate 99 is provided with a cleaning cotton 97, and a spring 98 is provided on the outer surface of the limiting column 95 between the U-shaped frame 96 and the pressure plate 73, and the two ends of the spring 98 are respectively fixedly connected to the fixing plate 99 and the corresponding U-shaped frame 96. In the process of the pressing roller 93 rolling and pressing the self-adhesive label paper, the cleaning cotton 97 is in contact with the surface of the pressing roller 93 under the action of the spring 98, and the colloid adhering to the surface of the pressing roller 93 is removed during the rolling of the pressing roller 93.

[0041] The working process and principle of the present invention are as follows:

[0042] Step 1: Pass one end of the self-adhesive label paper through the support roller and the pressure roller 5, and then fix it on the surface of the winding roller 2. The slider 11 drives the pressure roller 5 to fit the surface of the self-adhesive label paper under the action of the spring 10;

[0043] Step 2: Start the motor 3 to drive the reel 2 to rotate and reel the self-adhesive label paper. The pressure roller 5 rolls the self-adhesive label paper along the reeling direction under the action of the spring 10 to improve the fit between the label and the paper layer and to make the self-adhesive label evenly distributed on the label and the paper layer.

[0044] Step 3: When the self-adhesive label paper is being pulled, the pressing roller 5 rotates under the action of friction, and the electric push rod 62 repeatedly pushes and pulls the cleaning plate 63 to move along the surface of the pressing roller 5, and the cleaning cotton 64 wipes the excess colloid adhering to the surface of the pressing roller 5 to prevent the pressing roller 5 from adhering to the self-adhesive label paper during the rotation process;

[0045] When the cam 72 is dislocated with the rotating column 74, the pressing plate 73 drives the movable bar 75 to move downward, and the pressing roller 93 moves downward with the pressing plate 73, and drives the rotating plate 92 to rotate to one side under the joint action of the pressing plate 73 and the supporting plate 78.

When the cam 72 is dislocated with the rotating column 74, the pressing plate 73 drives the pressing roller 93 to move upward under the action of the spring 2 77;

[0046] Step 5: When the pressure roller 93 is rolling and pressing the self-adhesive label paper, the cleaning cotton 2 97 is in contact with the surface of the pressure roller 93 under the action of the spring 3 98, and removes the colloid adhering to the surface of the pressure roller 93 during the rolling process.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
