Technical Field

[0001] This utility model relates to the field of self-adhesive label production technology, specifically to a coating device for printed self-adhesive labels. Background Technology

[0002] Self-adhesive labels are a type of label material made of paper, film or other special materials as the face stock, coated with adhesive on the back, with silicone-coated release paper as the backing paper, and processed through printing, die-cutting and other processes. Compared with traditional labels, they have the advantages of not needing to apply glue, paste, or water, being pollution-free, and saving labeling time. They are convenient and quick to use and are widely used in daily chemical, pharmaceutical, electronics, logistics, food and other industries.

[0003] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0004] When applying self-adhesive coating to existing labels, the adhesive nozzle continuously dispenses adhesive for an extended period. Due to the adhesive's inherent stickiness and the small size of the dispensing equipment, the nozzle may become clogged, thus affecting the label coating efficiency.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a coating device for self-adhesive labels on printed materials, which solves the problem that the adhesive outlet may become clogged during prolonged dispensing of adhesive due to the adhesive's inherent adhesion, thereby reducing the coating efficiency of self-adhesive labels.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A coating device for self-adhesive labels of printed materials includes a label processing equipment body and a support frame fixedly installed on the top of the label processing equipment body. The self-adhesive coating equipment body is rotatably installed on the other side of the inner side of the support frame. An adhesive outlet is uniformly and fixedly installed through the bottom of the self-adhesive coating equipment body. A second servo motor fixedly connected to the rear end of the support frame is fixedly installed on the other side of the rear end of the support frame.

[0009] A support plate is movably installed on the other side of the inner side of the support frame, and a hydraulic push rod fixedly connected to the support plate is fixedly installed on the other side of the top of the support frame. An installation plate is provided at the bottom of the support plate, and needles aligned with the glue outlet are evenly fixedly installed at the bottom end of the installation plate.

[0010] Preferably, a conveyor belt is rotatably mounted on the top of the label processing equipment body, and a first servo motor is fixedly mounted on the other side of the rear end of the label processing equipment body and is fixedly connected to the conveyor belt bearing.

[0011] Preferably, a heating element is fixedly installed on the top of the self-adhesive coating equipment body, and a connecting pipe is fixedly connected to the front end of the self-adhesive coating equipment body.

[0012] Preferably, the front and rear ends of the other side of the support frame are provided with through grooves, and a sliding rod that is fixedly connected to the support plate is movably installed inside the through groove.

[0013] Preferably, the front and rear ends of the support plate are provided with limiting holes, the front and rear ends of the mounting plate are movably installed with limiting blocks extending into the limiting holes, and the front and rear ends of the mounting plate are fixedly installed with springs.

[0014] Preferably, a coating roller is rotatably mounted at the bottom inside the support frame, and a drying device is fixedly mounted on one side inside the support frame.

[0015] Compared with the prior art, this utility model provides a coating device for self-adhesive labels of printed materials, which has the following beneficial effects: When the glue outlet becomes blocked and the glue dispensing rate decreases, the second servo motor drives the main body of the self-adhesive coating equipment to rotate, so that the glue outlet rotates to the top. The output end of the hydraulic push rod drives the support plate to move downward inside the support frame, thereby driving the needle to move downward, so that the needle pierces the glue outlet and extends into the interior of the self-adhesive coating equipment body, thereby breaking through the blockage of the glue outlet. This avoids the situation where the glue outlet may become blocked due to the adhesive properties of self-adhesive labels, thus reducing the self-adhesive label coating efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a coating device for self-adhesive labels for printed materials.

[0024] Please see Figures 1-5 A coating device for self-adhesive labels for printed materials includes a label processing equipment body 1 and a support frame 2 fixedly installed on the top of the label processing equipment body 1. A conveyor belt 101 is rotatably installed on the top of the label processing equipment body 1. A first servo motor 102 fixedly connected to the bearing of the conveyor belt 101 is fixedly installed on the other side of the rear end of the label processing equipment body 1. A self-adhesive coating equipment body 201 is rotatably installed on the other side of the inner side of the support frame 2. An adhesive outlet 202 is uniformly and fixedly installed through the bottom of the self-adhesive coating equipment body 201. A second servo motor 203 fixedly connected to the rear end of the self-adhesive coating equipment body 201 is fixedly installed on the other side of the rear end of the support frame 2.

[0025] A support plate 3 is movably installed on the other side of the inner side of the support frame 2. A hydraulic push rod 301 fixedly connected to the support plate 3 is fixedly installed on the other side of the top of the support frame 2. An installation plate 302 is provided at the bottom of the support plate 3. Needles 303 aligned with the glue outlet 202 are evenly fixedly installed at the bottom end of the installation plate 302.

[0026] With the above-described structure, the self-adhesive label coating device for printed materials uses the output of the first servo motor 102 to drive the conveyor belt 101 to rotate and transport the printed labels, enabling the device to coat the labels with self-adhesive. If the glue outlet 202 becomes clogged after prolonged operation, reducing the glue dispensing rate, the output of the second servo motor 203 is controlled by a switch to rotate the main body 201 of the self-adhesive coating equipment, causing the glue outlet 202 to rotate to the top. Then, the output of the hydraulic push rod 301 drives the support plate 3 and the mounting plate 302 to move downward inside the support frame 2. Since the needle 303 is aligned with the glue outlet 202, the needle 303 pierces the glue outlet 202 and extends into the interior of the main body 201 of the self-adhesive coating equipment, thereby penetrating the clogged area of ​​the glue outlet 202. This solves the problem that the glue outlet 202 may become clogged and reduce the self-adhesive coating efficiency of the labels due to the adhesive properties of the self-adhesive.

[0027] Furthermore, a heating element 204 is fixedly installed on the top of the self-adhesive coating equipment body 201, and a connecting pipe 205 is fixedly connected to the front end of the self-adhesive coating equipment body 201. The connecting pipe 205 allows for the replenishment of self-adhesive to the interior of the self-adhesive coating equipment body 201, enabling continuous self-adhesive coating operations. The heating element 204 heats the interior of the self-adhesive coating equipment body 201, preventing the self-adhesive from sticking to the inner wall of the body.

[0028] Furthermore, a through groove 206 is provided at the front and rear ends of the other side of the support frame 2, and a slide rod 304 fixedly connected to the support plate 3 is movably installed inside the through groove 206. When the support plate 3 moves inside the support frame 2, the slide rod 304 slides inside the through groove 206, thereby making the movement of the support plate 3 more stable.

[0029] Furthermore, limiting holes 305 are provided at the front and rear ends of both sides of the support plate 3. Limiting blocks 306 extending into the limiting holes 305 are movably installed inside the front and rear ends of both sides of the mounting plate 302. Springs 307 are fixedly installed inside the front and rear ends of both sides of the mounting plate 302. When the needle 303 needs to be cleaned, pressing the limiting block 306 causes it to retract into the mounting plate 302, allowing one end of the limiting block 306 to slide out from the limiting hole 305. This allows the mounting plate 302 to be removed from the support plate 3 for cleaning the needle 303. After cleaning, the spring force of the spring 307 causes the limiting block 306 to extend into the limiting hole 305, fixing the mounting plate 302 inside the support plate 3 for easy operation by staff.

[0030] Furthermore, a coating roller 4 is rotatably installed at the bottom inside the support frame 2, and a drying device 5 is fixedly installed on one side inside the support frame 2. When the label surface is covered with self-adhesive, it is transported by the conveyor belt 101 and passes through the coating roller 4. The coating roller 4 brushes the self-adhesive, ensuring it is evenly distributed on the label surface. Then, it passes through the drying device 5, which dries the self-adhesive, allowing it to solidify and adhere stably to the label surface.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
