[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Example

[0025] A label coating device, such as Figures 1-4As shown, the device includes a main body 1, with an adhesive applicator 2 mounted on the top center of the main body 1. An adjustable limiting mechanism is provided at the front end of the adhesive applicator 2. The adhesive applicator also includes a control module. The adhesive applicator 2 includes a mounting frame 6, which is bolted to the top of the main body 1. A glue storage tank 8 is mounted on the upper end of the mounting frame 6 via a bracket. A lid 13 is mounted on the upper end of the glue storage tank 8 via an annular flange and bolts. The lid 13 has an adhesive inlet and a screw cap. A servo motor 14 is located in the middle of the top of the lid 13. A stirring shaft is mounted through the output end of the servo motor 14 and extends through the lid 13. Several stirring blades 15 are evenly mounted circumferentially on the side wall of the stirring shaft. An interactive panel 5 is mounted on one outer wall of the main body 1 via a bracket. The adhesive applicator also includes a tensioning mechanism, which includes a tension sensor and a swing-arm tensioning roller. The tension sensor detects the force on the label paper in real time and feeds it back to the control module. The control module adjusts the height of the tensioning roller via the servo motor. This mechanism is an existing technology and therefore its structure and principle are not shown or described in detail.

[0026] The glue application assembly 2 also includes a multi-head dispensing device 10, which is installed on the top inner side of the mounting frame 6. The multi-head dispensing device 10 is connected to the glue storage tank 8 through a pipe. The glue application device also includes a vision sensor, which is located on the top inner side of the mounting frame 6. By using the vision sensor to detect the width of the label paper, the dispensing heads of the multi-head dispensing device 10 are controlled to dispense glue onto the label paper. The multi-head dispensing device 10 adopts existing technology to achieve multi-head dispensing, and can control the amount of glue dispensed and whether the dispensing heads dispense glue. This solution is existing technology and will not be described in detail here. Rotating holes are provided at both the front and rear ends of the mounting frame 6, and a limit roller 12 is rotatably installed in the rotating holes. The outer wall of the mounting frame 6 is connected by a screw cap. Limiting roller 12 is installed to limit the label paper. Limiting roller 12 has an anti-slip coating. Limiting roller 12 is in contact with the backing paper of the label paper. The label paper is limited by limiting roller 12. The tension of the label paper is adjusted by the tensioning mechanism through contact between limiting roller 12 and the backing paper of the label paper. A horizontal plate is detachably installed on the mounting frame 6 by bolts. Rotating holes are symmetrically arranged on the horizontal plate. Glue roller 11 is rotatably installed in the rotating holes and limited by a screw cap. The surface of glue roller 11 is coated with a non-stick coating. The glue layer of the label paper is in contact with glue roller 11. A scraper is fixedly installed between glue rollers 11. The glue on the label paper is evenly spread by using the scraper. The non-stick coating on glue roller 11 can prevent it from sticking to the glue. By injecting glue into the glue storage tank 8, the servo motor 14 is driven by the control module to rotate the stirring shaft, thereby stirring the glue inside to prevent glue components from settling. At the same time, stirring can reduce its viscosity to a certain extent, making the glue easier to pour and shape, and facilitating the dispensing operation. The label paper is passed through the limit roller 12-glue roller 11-glue roller 11-limit roller 12 in sequence. The multi-head dispensing device 10 is used to dispense glue onto the coating layer of the label paper. During the movement of the label paper, the glue on the coating layer is spread evenly by using a scraper.

[0027] This device is further configured such as Figure 2 As shown, a heater 9 is installed on the glue storage tank 8. The interior of the glue storage tank 8 is equipped with a heat-conducting layer and a temperature sensor. By using the heater 9 to heat and keep the glue warm, the problem of the glue drying out when cooled is avoided.

[0028] This device is further configured such as Figure 1 As shown, the main body 1 of the device is equipped with a storage compartment, and a collection box 7 is installed in the storage compartment. The collection box 7 can be pulled out and is equipped with a transparent scale plate to facilitate observation of the glue volume inside. By using the collection box 7 to collect the scraped glue, it is convenient to reprocess it uniformly in the later stage, thereby reducing the production cost.

[0029] This device is further configured such as Figure 1As shown, a label roller frame 3 is installed on one side of the main body 1 of the device, and a label paper roll is installed on the label roller frame 3. The label paper roll can be replaced and removed.

[0030] This device is further configured such as Figure 1 As shown, the adhesive coating device also includes a surface activator 4, which is installed between the label roller frame 3 and the adhesive coating assembly 2. The surface activator 4 is existing technology and will not be described in detail here. By setting the surface activator 4, the adhesive layer of the label paper is activated, thereby improving the adhesion between the adhesive and the adhesive layer.

[0031] This device is further configured such as Figure 1 , Figure 4 As shown, the limiting mechanism includes mounting bases 16, which are installed in pairs at the end of the device body 1 away from the label roller frame 3. A groove is provided on the top of each mounting base 16, and a screw 18 is rotatably mounted in the groove. A handle 20 is provided on the top of each mounting base 16, passing through the mounting base 16 and connected to the screw 18. A lifting slide 19 is mounted on the screw 18, and a limiting roller 21 is rotatably mounted between the lifting slides 19. The surface of the limiting roller 21 is coated with a non-stick coating. A second limiting roller 17 is rotatably mounted on the lower half of the mounting base 16, and the surface of the second limiting roller 17 is coated with an anti-slip coating. By using the handle 20 to drive the screw 18 to rotate, the height of the limiting roller 21 is adjusted, thereby clamping the label paper.

[0032] The circuit connection between the control module and the individual components adopts existing technical solutions. The parts not involved in this device are the same as or can be implemented using existing technologies.

[0033] Working principle: The end of the label paper is removed from the label roller frame 3 and passed sequentially between the surface activator 4, limit roller 12, glue roller 11, glue roller 11, limit roller 12, limit roller 27, and limit roller 3 21. Finally, the label paper is clamped and rolled up using a traction device. The screw 18 is rotated by the rotating handle 20 to adjust the height of the limit roller 3 21, thereby clamping the label paper. Then, the glue is injected into the glue storage tank 8. The servo motor 14 drives the stirring plate 15 to rotate and stir the glue. At the same time, the glue is heated by the heater 9. According to the width of the label paper, the glue layer of the label paper is dripped using the multi-head dispensing device 10. The glue is spread evenly by the scraper. Excess glue flows into the collection box 7 for collection, which is convenient for later unified processing and reprocessing.

[0034] The above are merely preferred embodiments of this utility model. For parts that do not require creative effort in circuit control, signal control and transmission, please refer to the prior art. However, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and utility model concept of this utility model, should be included within the protection scope of this utility model.
