Description

Technical Field

[0001] This application relates to the field of label production technology, and in particular to a coating apparatus for label production. Background Technology

[0002] In the label manufacturing industry, lamination is a crucial process for enhancing the waterproofness, wear resistance, and aesthetics of labels, and the performance of the equipment directly impacts product quality and production efficiency. Traditional label lamination equipment often employs a fixed structure, relying on manual adjustment of the tension between the label paper and the laminating material. This is not only cumbersome and labor-intensive, but also difficult to precisely control the tension, easily leading to problems such as material wrinkles, misalignment, or even breakage during the lamination process, affecting lamination quality and yield.

[0003] While some automated laminating equipment is equipped with tension adjustment mechanisms, these are mostly based on a single mechanical or pneumatic adjustment method, lacking the ability to sense and dynamically respond to tension changes in real time. When processing label paper and laminating materials of different materials and thicknesses, the equipment cannot adaptively adjust, requiring frequent shutdowns to adjust parameters, which severely reduces production efficiency.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem that equipment cannot adaptively adjust when processing label paper and laminating materials of different materials and thicknesses, requiring frequent shutdowns for parameter adjustments and severely reducing production efficiency, this application provides a laminating device for label production.

[0006] The label production coating device provided in this application adopts the following technical solution:

[0007] A label production laminating device includes a frame, an internal groove for a laminating roller movably disposed within the groove, a set of guide rollers symmetrically distributed on both sides of the laminating roller, rotating blocks rotatably disposed on both sides of the inner wall of the frame, a connecting shaft fixed to one end of each rotating block, the guide rollers and the connecting shaft being rotatably connected, and rotating drum one and rotating drum two alternately disposed on the outer walls of both sides of the frame.

[0008] Preferably, positioning blocks are symmetrically fixed on both sides of the inner wall of the frame, and a damping spring for support is connected between the positioning blocks and the rotating block.

[0009] Preferably, a rotating shaft is rotatably connected at the center of the inner parts of the first and second rotating cylinders, and a support arm is connected to both ends of the rotating shaft.

[0010] Preferably, a fixing member is welded to one end of the support arm, and the fixing member is fixed to the outer wall of the frame by screws.

[0011] Preferably, a drive shaft is connected to the middle of both ends of the coating roller, one end of the drive shaft extends to the outside of the chute and is fitted with a fixing block, and the fixing block is fixed to the outer wall of the chute with screws.

[0012] Preferably, a motor is mounted on the outer wall of one of the fixing blocks, and the output end of the motor passes through the fixing block and drives the coating roller.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This application utilizes rotating drums one and two, securely mounted on a frame via a rotating shaft, support arm, and fixing components, to ensure smooth material roll conveying. Guide rollers, linked to rotating blocks, damping springs, and positioning blocks, sense material tension changes in real time and automatically adjust the guide roller position and angle to prevent loosening, wrinkling, or breakage, ensuring smooth conveying. A motor drives the coating rollers, using friction to synchronously pull the label paper and coating material forward, achieving efficient power transmission and precise synchronization. The entire system requires no frequent manual calibration and can adapt to different materials and thicknesses of raw materials. Through the extrusion of the coating rollers, a tight and flawless coating process is completed, significantly improving label production quality and efficiency. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a coating apparatus for label production. (Refer to...) Figures 1-2The system includes a frame 1, with a groove 7 inside the frame 1. A laminating roller 2 is movably mounted in the groove 7. A set of guide rollers 10 are symmetrically distributed on both sides of the laminating roller 2. Rotating blocks 13 are rotatably mounted on both sides of the inner wall of the frame 1. A connecting shaft 14 is fixed to one end of each rotating block 13. The guide rollers 10 and the connecting shaft 14 are rotatably connected. Rotary drums 5 and 6 are alternately mounted on the outer walls of both sides of the frame 1. The squeezing action of the laminating roller 2, combined with the smooth conveying and tension adjustment of the guide rollers 10, ensures that the label paper and the laminating material are tightly bonded, reducing defects such as bubbles and wrinkles, improving the quality of the finished label lamination and production efficiency, and providing high-quality semi-finished products for subsequent processing.

[0021] In this application, positioning blocks 11 are symmetrically fixed on both sides of the inner wall of the frame 1, and damping springs 12 for support are connected between the positioning blocks 11 and the rotating block 13. The guide roller 10 is connected to the rotatable rotating block 13 through the connecting shaft 14, and together with the positioning blocks 11 and the damping springs 12, they form a tension adaptive system. When the tension of the label paper or laminating material changes, the rotating block 13 rotates to drive the guide roller 10 to adjust its position and angle, and the damping springs 12 automatically extend and retract to buffer the change. This ensures that the material is conveyed smoothly and prevents breakage due to excessive tension or wrinkles due to insufficient tension, thus ensuring the continuous stability of the laminating process.

[0022] like Figure 3 As shown, a rotating shaft 9 is rotatably connected to the center of the inner parts of rotating drum 5 and rotating drum 6. Support arms 3 are connected to both ends of the rotating shaft 9, and a fixing piece 4 is welded to one end of each support arm 3. The fixing piece 4 is fixed to the outer wall of the frame 1 with screws. Rotating drum 5 and rotating drum 6 are connected to the frame 1 via the rotating shaft 9, support arms 3, and fixing piece 4, forming a stable triangular support structure. This ensures the stability of the label paper roll and the laminating material roll during rotation, preventing material shifting or entanglement due to shaking.

[0023] In this application, a drive shaft is connected to the middle of both ends of the laminating roller 2. One end of the drive shaft extends outside the slide 7 and is fitted with a fixing block 8. The fixing block 8 is fixed to the outer wall of the slide 7 with screws. A motor is installed on the outer wall of one of the fixing blocks 8. The output end of the motor passes through the fixing block 8 and drives the laminating roller 2. The motor drives the laminating roller 2 to rotate, and the friction between the laminating roller 2 and the material synchronously drives the label paper and the laminating material forward.

[0024] The implementation principle of a label production coating device according to an embodiment of this application is as follows:

[0025] During operation, the roll of label paper to be laminated is mounted on rotary drum 5, and the roll of laminating material is mounted on laminating roller 2. Rotary drum 5 and rotary drum 6 are securely mounted on both sides of the frame 1 via a rotating shaft 9 connected to a support arm 3 and a fixing member 4. The label paper is drawn out from rotary drum 5, passing between two guide rollers 10. The guide rollers 10 are rotatably connected to a rotating block 13 via a connecting shaft 14, and the rotating block 13 can rotate on the inner wall of the frame 1. At the same time, the laminating material is drawn out from laminating roller 2, similarly passing over the other side of the guide roller 10, and gradually adheres to the label paper under the guidance of the guide rollers 10.

[0026] When the motor is started, the motor output drives the laminating roller 2 to rotate. As the laminating roller 2 rotates, its surface comes into contact with the label paper and laminating material that are bonded together, generating friction and causing the label paper and laminating material to be conveyed forward synchronously. During the conveying process, the guide roller 10 plays a role in tensioning and guiding, ensuring that the label paper and laminating material are conveyed flatly.

[0027] Because a damping spring 12 connects the positioning block 11 and the rotating block 13, when the tension of the label paper or laminating material changes, the rotating block 13 can rotate around the inner wall of the frame 1 at a certain angle. The position and angle of the guide roller 10 are adjusted by the extension and retraction of the damping spring 12, thereby automatically adjusting the tension of the material and avoiding problems such as material loosening, wrinkling, or breakage. Finally, the label paper and laminating material are tightly bonded under the pressure of the laminating roller 2, completing the laminating process. The laminated label is output from the other side of the laminating roller 2 and enters the subsequent processing flow.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
