[0002] The label paper coating device is a device specially used to apply adhesive or other functional coatings on label paper. This device plays a key role in the production process of label paper, ensuring that the adhesive is evenly and accurately coated on the label paper, thereby improving the quality and performance of the label.

[0003] In the existing technology, firstly, some devices are unable to achieve accurate and uniform spraying of label paper, which may result in uneven distribution of paint, affecting product quality, and being unable to adapt to label paper of different sizes and shapes, limiting the application range of the equipment. The manual spraying method is inefficient and cannot meet the needs of large-scale production. Secondly, the connection and disassembly of the paint box and the spray assembly of some devices will become time-consuming, reducing production efficiency. The connection may not be strong enough, resulting in paint leakage or position displacement of the spray assembly. Replacing and maintaining the spray assembly will be more difficult, increasing downtime and maintenance costs. Finally, some devices are unable to accurately adjust the clamping rod, which may result in inaccurate connection between the spray assembly and the paint box, affecting the spraying effect. The operator may need to use more complicated methods to adjust the connection, which increases the difficulty and labor intensity of the operation. Utility Model Content

The lateral rod 14 is installed on both sides of the transverse frame 13.

[0030] In this embodiment, when the label paper enters the conveyor belt assembly 3, the spray assembly 2 is ready, the first cylinder 5 pushes the longitudinal plate 9 to move along the guide column, so that the transverse plate 8 and the paint box 30 are close to the label paper, and the second cylinder 6 pushes the transverse plate 8 to move transversely, so that the paint box 30 is accurately aligned with the position of the label paper, and the paint is transported from the paint box 30 to the spray assembly 2 through the connecting pipe 31.

[0031] The clamping auxiliary mechanism includes a rotating rack 17, a fixed plate 18, a rotating gear 19, a screw 20, a push block 21, a directional sleeve 22 and a return spring 23.

The rotation of the rotating gear 19 drives the screw 20 forward, and the screw 20 drives the push block 21. The push block 21 pushes the directional sleeve 22 to move longitudinally. The longitudinal movement of the movable sleeve causes the transverse frame 13 to move relative to the locking frame groove 25. The movement of the movable sleeve causes the slope groove 26 to push the lateral rod 14, thereby moving the transverse frame 13 away from the locking groove 12. The reset spring 23 returns the directional sleeve 22 to its initial position after the adjustment is completed, ensuring the stability of the adjustment.

A locking frame groove 25 is provided on the side wall of the directional sleeve 22, and slope grooves 26 are provided on both sides of the locking frame groove 25. The longitudinal movement of the movable sleeve causes the transverse frame 13 to move relative to the locking frame groove 25. The movement of the movable sleeve causes the slope groove 26 to push the lateral rod 14, thereby causing the transverse frame 13 to move away from the locking groove 12, and the longitudinal movement of the movable sleeve causes the slope groove 26 to push the lateral rod 14, thereby causing the transverse frame 13 to move away from the locking groove 12. Guide sleeves 27 are installed around the movable plate 9, and the guide sleeves 27 are movably installed on the guide columns. A guide block 28 is installed at the bottom of the transverse plate 8, and a slide rail 29 is installed on the top of the longitudinal plate 9, and the guide block 28 is installed on the slide rail 29 for guidance.

[0034] More specifically, ensure that all mechanisms are in their initial positions, the paint box 30 is filled with paint, the label paper is on the conveyor belt, start the conveyor belt assembly 3, the label paper starts to move, and the mobile spraying mechanism sprays according to the position of the label paper. At the same time, the quick clamping mechanism ensures a stable connection between the paint box 30 and the spraying assembly 2. As the label paper moves, the mobile spraying mechanism continues to spray until the label paper processing is completed. After the processing is completed, stop the conveyor belt assembly 3, separate and clean the spraying assembly 2 and the paint box 30 through the quick clamping mechanism, perform maintenance and inspection, and prepare for the next operation.

[0035] In summary, when the overall equipment is in use or running: when the spray mechanism needs to be moved, when the label paper enters the conveyor belt assembly 3, the spray assembly 2 is ready, the first cylinder 5 pushes the longitudinal plate 9 to move along the guide column, so that the transverse plate 8 and the paint box 30 are close to the label paper, the second cylinder 6 pushes the transverse plate 8 to move laterally, so that the paint box 30 is accurately aligned with the position of the label paper, and the paint is transported from the paint box 30 to the spray assembly 2 through the connecting pipe 31, and the spray assembly 2 sprays the paint evenly onto the label paper.

[0036] When the quick clamping mechanism is required to be operated, the paint box 30 and the spray assembly 2 can be quickly installed and disassembled. One end of the clamping rod 11 extends into the interior of the clamping tube 10, and the transverse frame 13 is located on the side wall of the clamping tube 10. When the paint box 30 and the spray assembly 2 need to be connected or disconnected, one end of the clamping rod 11 compresses the rubber pad 16 to form a sealed connection with the interior of the clamping tube 10. The transverse frame 13 moves under the action of the push spring 15, so that the locking groove 12 is clamped with the side of the clamping rod 11, fixing the connection between the paint box 30 and the spray assembly 2. When release is required, the transverse frame 13 moves to release the clamping.

[0037] When the operation of the clamping auxiliary mechanism is required, when the precise position of the clamping mechanism needs to be adjusted, the operator rotates the rotating gear 19, rotates the rotating rack 17, and drives the rotating gear 19 on the top of the fixed plate 18 to rotate. The rotation of the rotating gear 19 drives the screw 20 forward, and the screw 20 drives the push block 21, and the push block 21 pushes the directional sleeve 22 to move longitudinally. The longitudinal movement of the movable sleeve causes the transverse frame 13 to move relative to the locking frame groove 25. The movement of the movable sleeve causes the slope groove 26 to push the lateral rod 14, thereby moving the transverse frame 13 away from the locking groove 12. The reset spring 23 returns the directional sleeve 22 to its initial position after the adjustment is completed, ensuring the stability of the adjustment.

[0038] Ensure that all mechanisms are in their initial positions, the paint box 30 is filled with paint, the label paper is on the conveyor belt, start the conveyor belt assembly 3, the label paper starts to move, and the mobile spraying mechanism sprays according to the position of the label paper. At the same time, the quick clamping mechanism ensures a stable connection between the paint box 30 and the spraying assembly 2. As the label paper moves, the mobile spraying mechanism continues to spray until the label paper processing is completed. After the processing is completed, stop the conveyor belt assembly 3, separate and clean the spraying assembly 2 and the paint box 30 through the quick clamping mechanism, perform maintenance and repair, and prepare for the next operation.
