Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive coating equipment technology, and in particular to an adhesive coating equipment for self-adhesive labels. Background Technology
[0002] In the traditional self-adhesive label production process, the adhesive coating process is a crucial step in determining label quality. Traditional adhesive coating equipment has many limitations. Many adhesive coating devices have a fixed nozzle spacing, making it difficult to flexibly adjust according to the width of different label papers and diverse spraying needs. This results in them being only applicable to specific sizes of label papers, with poor versatility. When faced with adhesive coating tasks for label papers of different sizes, different equipment often needs to be changed, which greatly reduces production efficiency and increases production costs. At the same time, during storage and use, the adhesive is prone to sedimentation due to the lack of effective stirring and heating measures. Especially in low-temperature environments, the adhesive is prone to solidification, leading to poor fluidity and affecting the uniformity and quality of the adhesive coating. This results in inconsistent adhesive coating effects on the label papers and reduces the product qualification rate. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings:
[0022] like Figures 1-5 As shown, this embodiment provides a self-adhesive label coating device, including a support plate 1, a mounting frame 2 on the support plate 1, an adhesive storage tank 3 rotatably mounted between the mounting frames 2, an unwinding shaft 4 for attaching label rolls on the mounting frames 2, the unwinding shaft 4 being linked with the adhesive storage tank 3, and a motor 5 on the mounting frames 2 for driving the unwinding shaft 4. The rotation of the motor 5 drives the unwinding shaft 4 to rotate, thereby unwinding the label roll attached to the unwinding shaft 4. A connecting frame 6 is provided on the side, and a pump body 7 is provided on the connecting frame 6. The inlet end of the pump body 7 is connected to the glue storage tank 3. An adjustable spraying component 8 for spraying glue is provided on the connecting frame 6. The output end of the pump body 7 is connected to the adjustable spraying component 8. The glue inside the glue storage tank 3 is transferred to the adjustable spraying component 8 through the pump body 7. A telescopic cylinder 9 is provided on the connecting frame 6 for adjusting the adjustable spraying component 8. The position of the adjustable spraying component 8 can be flexibly adjusted by telescopically extending and retracting the cylinder.
[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 5As shown, the adjustable spraying assembly 8 includes a slide rail 801 and a dispensing pipe 802. The slide rail 801 is installed between the output ends of the telescopic cylinder 9, and the dispensing pipe 802 is fixedly connected to the output end of the pump body 7. Multiple spray heads 803 are slidably connected to the slide rail 801. Each spray head 803 is connected to an inlet pipe 804, the other end of which is connected to the dispensing pipe 802. The inlet pipe 804 is made of flexible tubing. The pump body 7 draws in the glue from the glue container 3 through the inlet end and then delivers it to the dispensing pipe 802 from the output end. Since the dispensing pipe 802 is connected to the multiple spray heads 803 through the flexible inlet pipe 804, the glue is evenly distributed to each spray head 803. In the process, the spray head 803 evenly sprays glue onto the label paper, completing the glue application of the self-adhesive label. The slide rail 801 has a waist-shaped hole 805 on one side, and a screw 806 is connected to the spray head 803. The screw 806 slides and engages with the waist-shaped hole 805. A clamping nut 807 is threaded onto the screw 806. According to the width of the label paper and the actual glue application requirements, the position of the slide rail 801 is adjusted by the telescopic cylinder 9 to change the overall spraying position range. The spray head 803 is slid to move the screw 806 in the waist-shaped hole 805, adjusting the spacing between the spray heads 803. After adjustment, the clamping nut 807 is tightened to fix the position of the spray head 803.
[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 3 As shown, a heating plate 10 is installed on the outside of the glue placement tank 3. A drive sprocket 11 is connected to the unwinding shaft 4. A driven sprocket 12 is provided on the glue placement tank 3. A chain 13 meshes between the drive sprocket 11 and the driven sprocket 12. A guide roller 14 is provided on the connecting frame 6. The guide roller 14 guides the label paper, so that the label paper can be smoothly conveyed to the bottom of the adjustable spraying assembly 8. A sealing block 15 is plugged into the glue placement tank 3. The motor 5 drives the unwinding shaft 4 to rotate. Since the drive sprocket 11 connected to the unwinding shaft 4 and the driven sprocket 12 on the glue placement tank 3 are meshed through the chain 13, the rotation of the unwinding shaft 4 will drive the glue placement tank 3 to rotate synchronously, ensuring that the glue in the glue placement tank 3 can be mixed evenly and avoiding sedimentation.
[0025] In use, this utility model is connected to an external power source. The sealing block 15 is removed from the glue container 3, and an appropriate amount of glue is added to the container. After adding the glue, the sealing block 15 is replaced to prevent glue leakage and the entry of external impurities. The heating plate 10 is activated to heat the glue in the container 3, maintaining its good fluidity to ensure smooth subsequent spraying. The label roll is attached to the unwinding shaft 4. Based on the width of the label and the actual glue application requirements, the position of the slide rail 801 is adjusted using the telescopic cylinder 9 to change the overall spraying range. The spray head 803 is slid, causing the screw 806 to move within the oblong hole 805, adjusting the spacing between the spray heads 803. After adjustment, the clamping nut 807 is tightened to fix the position of the spray head 803. This allows for precise control of the glue spraying range and density to adapt to the glue application requirements of different label sizes. The motor 5 is then activated. The unwinding shaft 4 rotates. Since the driving sprocket 11 connected to the unwinding shaft 4 is engaged with the driven sprocket 12 on the glue placement tank 3 through the chain 13, the rotation of the unwinding shaft 4 will drive the glue placement tank 3 to rotate synchronously, ensuring that the glue in the glue placement tank 3 can be mixed evenly and avoiding sedimentation. The label paper to be coated is placed under the guide roller 14. The guide roller 14 guides the label paper, allowing it to be smoothly transported to the adjustable spraying assembly 8. The pump body 7 is started, and the pump body 7 draws the glue in the glue placement tank 3 through the inlet end and then delivers it to the distribution pipe 802 from the outlet end. Since the distribution pipe 802 is connected to multiple spraying heads 803 through the inlet pipe 804 made of flexible material, the glue will be evenly distributed to each spraying head 803. When the label paper passes under the adjustable spraying assembly 8 at a constant speed, the spraying head 803 sprays the glue evenly onto the label paper, completing the coating work of the self-adhesive label.
