The unwinding guide roller 6 is rotatably connected to the upper side of the laminating machine wall panel 1. The driving device 7 is respectively connected to the metering rubber roller 3 and the glue transfer rubber roller 4, and is rotatably connected to the eccentric roller 5 on the laminating machine wall panel 1. During the coating process, the material is first introduced by the unwinding guide roller 6, and enters the glue coating gap 32 close to the glue coating steel roller 2, and then passes through the coating gap 41 close to the glue coating transfer rubber roller 4 for secondary coating. Then the material bypasses the outer side of the glue coating transfer rubber roller 4 and is discharged after adjustment by the eccentric roller 5.

[0047] The consistency and quality of the coating are guaranteed. By finely adjusting the glue coating gap and the coating gap, the device can adapt to materials of different thicknesses and types to ensure uniform and flawless coating. The design of the unwinding guide roller and the eccentric roller improves the tension and position control of the material, making the coating process smoother and reducing the warping and wrinkling of the material. The rotating steel roller assembly and disassembly structure simplifies the replacement of the roller, reduces downtime and improves production efficiency.

[0048] Furthermore, the rotating roller assembly and disassembly structure includes a first glue coating roller driven shaft 81, a second glue coating roller driven shaft 82 and a metering rubber roller shaft pressure plate 83. The first glue coating roller driven shaft 81 is connected to the second glue coating roller driven shaft 82 and rotates together. The second glue coating roller driven shaft 82 is also detachably connected to the metering rubber roller shaft pressure plate 83 to form a mounting position 88. The mounting position 88 is used to install the metering rubber roller 3. The metering rubber roller shaft pressure plate 83 and the second glue coating roller driven shaft 82 are both provided with a locking structure 84. Removing the locking structure 84 can move the glue transfer rubber roller 4 out of the mounting position 88.

[0049] The rotating roller assembly and disassembly structure optimizes the roller shaft connection mode of the coating machine, wherein the driven shaft of the first glue pressure roller is connected to the driven shaft of the second glue pressure roller and rotates together. The driven shaft of the second glue pressure roller is provided with a detachable connection to the metering rubber roller shaft pressure plate, and this configuration forms a mounting position dedicated to installing the metering rubber roller. The design of the locking structure allows the glue transfer rubber roller to be quickly removed and replaced from the machine when needed without the need for a complicated disassembly process.

[0050] The advantage of this structure is that it significantly improves the maintenance efficiency and flexibility of the coating machine. The introduction of the locking structure allows operators to quickly replace the roller, greatly shortening the downtime of the machine. In addition, this design also improves the safety of the equipment because it can reduce accidents or damage that may occur during the disassembly process. In general, this optimization enhances the continuity of the coating process and the reliability of production.

[0051] Further, a small inclined surface 85 is formed on the inner side of both ends of the connection between the second glue roller driven shaft 82 and the metering rubber roller shaft pressure plate 83, and the small inclined surface 85 is respectively biased to the outer side of both ends. After the metering rubber roller shaft pressure plate 83 is disassembled, an opening 86 is formed on the second glue roller driven shaft 82, and the length of the opening 86 is slightly larger than the diameter of the formed mounting position 88. The locking structure 84 includes a first locking structure 841 and a second locking structure 842. The first locking structure 841 is arranged at the connection between the second glue roller driven shaft 82 and the metering rubber roller shaft pressure plate 83 at both ends, and the second locking structure 842 is respectively arranged on the second glue roller driven shaft 82 and the metering rubber roller shaft pressure plate 83, and extends into the mounting position 88. The portion of the metering rubber roller 3 extending into the mounting position 88 is the metering A rubber roller connecting seat 87, one end of the metering rubber roller connecting seat 87 is provided with a first opening 871 corresponding to the second locking structure 842, the first opening 871 cooperates with the second locking structure 842 to fix the metering rubber roller 3, the other end of the metering rubber roller connecting seat 87 is connected to the metering rubber roller 3, the first locking structure 841 is provided with a second opening 8411, a bolt 8412 and a groove 8413, the second opening 8411 is provided at the connection between the two ends of the metering rubber roller shaft pressure plate 83, the groove 8413 is provided at the connection between the two ends of the second glue coating roller driven shaft 82, and the size of the groove 8413 corresponds to the bolt 8412, the bolt 8412 passes through the second opening 8411 and extends into the groove 8413 to be connected to the second glue coating roller driven shaft 82.

[0052] The connection between the driven shaft of the second glue coating roller and the shaft pressure plate of the metering rubber roller is designed with a special inclined surface and opening structure, so that the shaft pressure plate can be easily removed and installed. The design of the inclined surface and opening, with an opening whose length is slightly larger than the diameter of the installation position, provides a position for the metering rubber roller to be easily accessed and removed. The first locking structure is located at the connection between the driven shaft and the shaft pressure plate, while the second locking structure fixes the metering rubber roller. This design ensures the stability and precise alignment of the metering rubber roller during operation; the advantage of this mechanical design is that it improves the installation and disassembly efficiency of the roller shaft and saves time for maintenance and replacement of the roller shaft. The structure of the opening and inclined surface simplifies the assembly process, allows the roller shaft to be quickly fixed in place, and improves the safety performance of the machine. The application of the locking structure ensures stability and accuracy during operation, while reducing the risk of failure due to improper assembly, and improving the reliability and production efficiency of the overall equipment.

[0053] Furthermore, a first roller bearing 811 is installed on the driven shaft 81 of the first glue roller, and a second roller bearing 812 is also provided on the end of the metering rubber roller connecting seat 87 connected to the metering rubber roller. The second roller bearing 812 rotates together with the metering rubber roller 3, and drives the metering rubber roller connecting seat 87 and the first glue roller driven shaft 81, the first roller bearing 811 and the second glue roller driven shaft 82 to rotate. A fixing part 813, a sliding part 814 and a driving part 815 are also provided on the driven shaft 81 of the first glue roller.

The driving part 815 is arranged below the sliding part 814, and the driving part 815 can drive the sliding part 814 to move up and down.

[0054] The driven shaft of the first glue roller is equipped with a first roller bearing, while the metering roller is connected to the connecting seat through a second roller bearing. This configuration allows the second roller bearing to rotate with the metering roller and drive the connecting seat and the first and second glue roller driven shafts to work together. In addition, the fixed part, the sliding part and the driving part together constitute a power transmission system. The fixed part is connected to the driven shaft and mounted on a sliding part that can move vertically along the wall of the laminating machine; the advantage of this design is that it provides a stable and adjustable transmission mechanism to ensure uniform distribution and precise control of the coating pressure. The first and second roller bearings ensure the smooth rotation of the glue roller and reduce friction and wear during movement. The driving part allows the sliding part to move vertically along the wall of the machine, so that the position of the glue roller can be adjusted to achieve fine adjustment of the coating pressure.

[0055] Furthermore, the eccentric roller 5 is further provided with an eccentric adjusting member 51, the eccentric adjusting member 51 is connected to the eccentric roller 5, and two eccentric adjusting members 51 are provided and are located at both ends of the eccentric roller 5, the eccentric adjusting member 51 is provided with a base shaft section 511, a concentric shaft section 512, an eccentric shaft section 513 and a first fixing assembly 514, the concentric shaft section 512 and the eccentric shaft section 513 are located on both sides of the base shaft section 511, and the concentric shaft section 512 and the base shaft section 511 are connected to each other. The central axis of the eccentric shaft segment 513 and the base shaft segment 511 do not coincide with each other. The eccentric shaft segment 513 is connected to the eccentric roller 5. The concentric shaft segment 512 is fixed to a fixing seat 516 provided on the first fixing component 514 through a fastener 515 provided on the first fixing component 514. Adjusting the fastener 515 and the concentric shaft segment 512 will drive the eccentric shaft segment 513 to rotate, thereby adjusting the central axis of the eccentric roller 5.

[0056] The eccentric adjustment member on the eccentric roller is a precision component used to fine-tune the position of the eccentric roller. Each eccentric adjustment member includes a base shaft segment, a concentric shaft segment, an eccentric shaft segment, and a first fixed component. The concentric shaft segment is located on the central axis of the base shaft segment, while the eccentric shaft segment deviates from the central axis and is connected to the eccentric roller. By adjusting the fasteners on the concentric shaft segment, the rotation of the eccentric shaft segment can be precisely controlled, thereby changing the position of the central axis of the eccentric roller.

[0057] The main advantage of this design is that it provides extremely high adjustment accuracy, allowing the operator to adjust the position of the eccentric roller according to coating requirements. This ability to accurately control the eccentricity is essential to ensure uniform distribution of paint and control coating thickness.

[0058] The metering rubber roller 3 is also provided with a heat circulating water system 31, and the heat circulating water system 31 comprises:

[0059] A second fixing assembly 311, the second fixing assembly 311 comprises a metering rubber roller fixing seat 3111 and a quick-release driving shaft 3112, the quick-release driving shaft 3112 is provided with a pressure plate mounting position 3113 and the quick-release driving shaft 3112 is rotatably connected to the metering rubber roller fixing seat 3111;

[0062] The hot circulating water system achieves temperature control through a water supply structure set inside the metering rubber roller. The system includes a fixed component and a quick-release driving shaft rotatably connected thereto. The driving shaft is provided with a pressure plate mounting position, which can be quickly disassembled and connected. The water supply structure is connected to the quick-release driving shaft and extends into the pressure plate mounting position, so that water can flow into the metering rubber roller. The advantage of this design is that it allows the temperature of the metering rubber roller to be accurately controlled through the water circulation system, thereby affecting the viscosity and fluidity of the coating material. This temperature control plays an important role in maintaining the quality of the coating and the coating effect. The cavity design of the rotating steel roller structure ensures that the water circulation will not be affected by the rotation of the roller, ensuring the stable operation of the system and the uniform distribution of heat energy, thereby improving production efficiency and product quality.

[0063] Furthermore, the metering rubber roller 3 is also provided with a metering rubber roller rotating component 33, a sliding component 34 and an adjusting component 35.

[0064] The rotating assembly, sliding assembly and adjusting assembly on the metering roller work together to adjust the coating gap. The rotating assembly enables the metering roller to rotate smoothly, while the sliding assembly is connected to the inner side of the laminator wall panel, allowing the metering roller to move along a certain trajectory. The adjusting assembly is responsible for controlling the movement of the sliding assembly. In this way, the gap between the metering roller and the coating steel roller can be accurately adjusted, thereby affecting the thickness and uniformity of the coating. The advantage of this design is that it provides a method for accurately adjusting the coating gap, ensuring uniform distribution and quality control of the coating during the coating process. By using the adjusting assembly and the sliding assembly together, the coating gap can be quickly and easily adjusted to adapt to changes in different materials and coating requirements.
