Description

Technical Field

[0001] The utility model belongs to the technical field of label production, and in particular relates to a gluing device for adhesive label paper. Background Art

[0002] Label paper, also known as barcode paper, is a printing material widely used in various industries. It is mainly used to make various labels and instructions. It is usually composed of base paper, face paper and adhesive. It is widely used in office and stationery, medical supplies, commerce and retail, industrial manufacturing, environmental protection and other fields.

[0003] In the production process of label paper, gluing is a key link that determines the stickiness and use effect of the label. Traditional label paper gluing equipment usually adopts a method of guiding the label paper in the air and then using a rubber roller to apply glue to achieve the gluing operation of the label paper. However, in the actual production process, it is found that since the label paper is guided in the air, the label paper lacks support during the gluing process. Due to the influence of the rubber roller pressing against the glue, the label paper is prone to loosening and wrinkling, which affects the gluing effect and finished product quality of the label paper. For this reason, the present application proposes a gluing device for adhesive label paper. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] This embodiment provides a device for gluing adhesive label paper, and its structural diagram is shown as follows: Figure 1-Figure 5As shown, it includes a workbench 1, one end of the workbench 1 is provided with a feeding roller 4 with label paper wound on it, side panels 2 are provided on both sides of the top of the workbench 1, a conveyor belt 3 for conveying label paper is installed between a pair of side panels 2, and the workbench 1 is equipped with a gluing component 5 located above the conveyor belt 3, and the gluing component 5 includes a fixed arm 20 fixed on one side of the workbench 1, a glue storage box 21 fixed on the top of the fixed arm 20, and a glue roller 22 installed at the bottom of the glue storage box 21. The glue in the glue storage box 21 can flow to the glue roller 22 for gluing operation. There are several air holes 7 on the conveyor belt 3, and an air suction component 6 is installed on the side plate 2 to generate negative pressure in the conveyor belt 3. The air suction component 6 includes a first frame 9 fixed on the side plate 2, and the first frame 9 passes through the side plate 2 and is connected to the middle of the conveyor belt 3. An exhaust fan 10 is installed in the first frame 9. After the label paper wound on the unwinding roller 4 is unfolded and attached to the conveyor belt 3, it is transported under the glue roller 22. The exhaust fan 10 in the first frame 9 is started to continuously pump the air in the conveyor belt 3 outwards, generating negative pressure in the conveyor belt 3, and then Several air holes 7 on the belt 3 generate negative pressure. The air holes 7 located at the top of the conveyor belt 3 use the negative pressure to absorb the conveyed label paper, so that the label paper can be conveyed in contact with the top surface of the conveyor belt 3. The gluing roller 22 glues the label paper conveyed in contact with the top surface of the conveyor belt 3, and adopts the negative pressure adsorption method to make the label paper be conveyed in contact with the conveyor belt 3 for gluing. Compared with the traditional structure of gluing in which the label paper is transported in the air, the bottom of the label paper is subjected to force, and the label paper can be unfolded flatly to avoid wrinkles, thereby ensuring the gluing effect of the label paper.

[0026] Furthermore, a third plate frame 17 is provided on the upper surface of the workbench 1, and a sealing film 18 is laid inside the third plate frame 17 for sealing the air holes 7 at the bottom of the conveyor belt 3 to ensure that the air holes 7 at the top of the conveyor belt 3 can absorb the label paper.

[0027] In this embodiment, a first plate frame 11 is installed at one end of the first frame body 9 away from the side plate 2 , and a protective net 12 is installed in the first plate frame 11 to play a protective role.

[0028] Furthermore, in this embodiment, a support frame 19 is provided at the bottom of the workbench 1, and a drying component 8 is provided on the top of a pair of side panels 2. The drying component 8 includes a second frame 13 fixed on the top of the pair of side panels 2. The second frame 13 is located on the side of the gluing component 5 away from the discharge roller 4. A supply fan 14 is installed in the second frame 13. A second plate frame 15 is provided on the top of the second frame 13. A heating wire 16 is installed in the second plate frame 15. After the label paper is glued, it is conveyed under the second frame 13. With the heating cooperation of the heating wire 16, the supply fan 14 is started to blow air toward the conveyor belt 3, so that the label paper conveyed to the conveyor belt 3 and glued can be dried, thereby ensuring that the glue is fully cured.

[0029] Working principle: When in use, the label paper wound on the unwinding roller 4 is unwound and attached to the conveyor belt 3 and transported under the glue coating roller 22. At the same time, the exhaust fan 10 in the first frame 9 is started to continuously pump the air in the conveyor belt 3 outwards, generating negative pressure in the conveyor belt 3, and then generating negative pressure at several air holes 7 on the conveyor belt 3. The air holes 7 at the bottom of the conveyor belt 3 are blocked by the sealing film 18, and the air holes 7 at the top of the conveyor belt 3 use the negative pressure to absorb the conveyed label paper, so that the label paper can be conveyed in contact with the top surface of the conveyor belt 3. The glue coating roller 22 glues the label paper conveyed in contact with the top surface of the conveyor belt 3. After the label paper is glued, After being transported under the second frame 13, the air supply fan 14 is started to blow air toward the conveyor belt 3 under the heating cooperation of the electric heating wire 16, so as to dry the label paper after being conveyed and glued on the conveyor belt 3 to ensure that the glue is fully solidified. Finally, the label paper is transported to the next processing step through the conveyor belt 3. During the whole process, negative pressure adsorption is adopted to make the label paper be conveyed on the conveyor belt 3 for gluing and drying. Compared with the traditional structure of transporting the label paper in the air for gluing and drying, the bottom of the label paper is subjected to force, and the label paper can be unfolded flatly to avoid wrinkles, thereby ensuring the gluing effect of the label paper and improving the quality of the finished label paper.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
