[0001] The utility model relates to the technical field of self-adhesive paper processing, in particular to a back-side gluing device for safety line self-adhesive paper. Background Art
[0002] Self-adhesive paper is mostly made of high-strength white board paper as the base paper, coated with self-adhesive paper. There is a security line inside the self-adhesive paper to make it anti-counterfeiting. The main use of self-adhesive paper is to print trademarks and labels.
[0003] When gluing the self-adhesive paper, some self-adhesive papers need to be glued not only on the front side but also on the back side. However, most of the current gluing devices only have a front side gluing unit. When the self-adhesive paper is transmitted, only the front side can be glued. If the back side needs to be glued, additional equipment can only be installed to achieve this, which is more costly. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a back-side gluing device for safety line self-adhesive paper.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A gluing mechanism and a glue outlet plate are arranged between the two side supporting mechanisms, and a glue outlet system is arranged on the surface of the side walls of both sides of the workbench and on one side of the supporting mechanism.
[0008] In addition, a preferred structure is that an opening is provided on the upper surface of the workbench, and supporting feet are fixedly provided at the four corners of the bottom surface of the workbench.

[0010] In addition, a preferred structure is that the support mechanism includes a fixed seat, which is fixed on both sides of the upper surface of the workbench, and a telescopic rod is provided at the bottom of the upper end seat body of the fixed seat, and the other end of the telescopic rod away from the fixed seat is fixedly connected to a rotating seat.

[0012] In addition, a preferred structure is that the gluing mechanism includes a rubber cylinder, and rotating shafts are arranged on both sides of the rubber cylinder body, and the rotating shafts on both sides are rotatably arranged on a rotating seat.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Reference Figure 1-6 A back-side gluing device for a safety line self-adhesive paper comprises a workbench 1, a front-side gluing unit 5 is arranged in the middle of the upper surface of the workbench 1, driving roller units 4 are symmetrically arranged on both sides of the front-side gluing unit 5 on the workbench 1, and a back-side gluing unit 6 is arranged below the front-side gluing unit 5;
[0024] The back glue coating unit 6 includes a support mechanism 61, which is symmetrically installed in the middle of the two sides of the workbench 1. A glue application mechanism 62 and a glue discharge plate 64 are arranged between the two side support mechanisms 61. A glue discharge system 63 is arranged on the surface of the side walls of the two sides of the workbench 1 and on one side of the support mechanism 61.
[0025] Among them, an opening 12 is opened on the upper surface of the workbench 1, and supporting feet 11 are fixedly installed at the four corners of the bottom surface of the workbench 1. Placement plates 3 are arranged on the side walls of the supporting feet 11 on both sides of the workbench 1. Glue collecting boxes 2 are placed on the upper surfaces of the placement plates 3 on both sides. The glue collecting boxes 2 are convenient for collecting glue dripping from the back gluing unit 6 and the one side driving roller unit 4.
[0026] In addition, the supporting mechanism 61 includes a fixed seat 611, which is fixed on both sides of the upper surface of the workbench 1. A telescopic rod 612 is provided at the bottom of the upper end of the fixed seat 611. The other end of the telescopic rod 612 away from the fixed seat 611 is fixedly connected to a rotating seat 614. The telescopic rod 612 enables the rotating seat 614 to move up and down.
[0027] Moreover, a spring 613 is sleeved on the outside of the telescopic rod 612, one end of the spring 613 is fixed to the bottom of the upper end seat body of the fixed seat 611, and the other end is fixedly connected to the upper surface of the rotating seat 614. A gluing mechanism 62 is rotatably arranged between the rotating seats 614 on both sides. In combination with the characteristics of the spring 613, the glue cylinder 621 can cooperate with the roller of the front gluing unit 5 to press the self-adhesive paper.
[0028] In addition, the gluing mechanism 62 includes a glue cylinder 621, and a rotating shaft 622 is set on both sides of the cylinder body of the glue cylinder 621. The rotating shaft 622 on both sides is rotatably set on the rotating seat 614. The glue cylinder 621 cooperates with the rotation of the rotating shaft 622 to attach the glue on the glue cylinder 621 to the back of the self-adhesive paper.
[0029] Moreover, the glue outlet of the glue discharge plate 64 is aligned with the glue cylinder 621, and connecting pipes connected to the glue discharge system 63 are arranged on both sides of the glue discharge plate 64. The connecting rods on both sides of the glue discharge plate 64 are fixed on the side walls of the rotating seat 614. The glue discharge system 63 is a device that can automatically and quantitatively transport glue to the glue discharge plate 64, and the glue discharge plate 64 is a device that can discharge glue evenly and drip onto the glue cylinder 621. Both of these devices are prior arts and are well known to people in the field of glue coating devices. There is no need to elaborate on their structures and distances.
[0030] In this embodiment, when the front gluing unit 5 is applying glue, the driving roller units 4 on both sides are used to transmit the self-adhesive paper. During this process, the springs 613 on both sides contract and cooperate with the telescopic rod 612, so that the rotating seat 614 can approach the fixed seat 611, so that the glue cylinder 621 can be close to the self-adhesive paper, thereby cooperating with the roller of the front gluing unit 5 to tightly stick the self-adhesive paper, but because the contraction force of the spring 613 is not large, the self-adhesive paper will not be crushed. During this process, the glue discharge system 63 will continue to transport glue to the glue discharge plate 64.
[0031] The glue discharging plate 64 will evenly discharge the glue, and the glue will evenly drip onto the glue cylinder 621 under the action of gravity, and then the glue cylinder 621 will apply the glue to the back of the self-adhesive paper by rolling, thereby completing the work of gluing the back of the self-adhesive paper, and in the process of gluing, the dripping glue will be collected by the glue collecting box 2, thereby ensuring the cleanliness of the working environment.
[0032] In the utility model, a back gluing unit 6 is arranged below the front gluing unit 5, so that when the front gluing unit 5 performs gluing on the front side of the security self-adhesive paper, the glue cylinder 621 at the bottom can also apply glue to the back side of the self-adhesive paper by rolling, and the supporting mechanism 61 can ensure that the glue cylinder 621 is always attached to the back side of the self-adhesive paper. Such a design can make the glue cylinder 621 stick tightly when applying glue to self-adhesive papers of different thicknesses. This gluing device realizes simultaneous gluing on the front and back sides, effectively saving costs, and no additional equipment is required for special back gluing.
[0033] 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. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
