[0022] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0023] An automatic label-attaching device for hot melt adhesive spreaders with label buffers, such as Figures 1-5 As shown, the system includes a frame 1 and label roll 2, a fixed label receiving module 3, and a sliding label receiving module 4 connected to the frame 1. There are multiple sets of label roll 2; in this embodiment, there are eight sets, arranged at intervals below the frame 1. Specifically, the label roll 2 is slidably connected to the frame 1, and can slide to the inside or outside of the frame 1. When the label roll 2 slides to the inside of the frame 1, it forms a label receiving station; when it slides to the outside, it forms a label changing station. The label roll 2 is equipped with a mandrel, and the label 5 is fixedly connected to the mandrel. When the label 5 is used up, the label roll 2 slides to the label changing station to replace the label 5; after the label 5 is replaced, the label roll 2 slides to the label receiving station to stand by.

[0024] Fixed label receiving modules 3 are fixedly connected to the frame 1, and their number is the same as that of the label roll tubes 2, with each tube corresponding to one of the label roll tubes 2. Sliding label receiving modules 4 are slidably connected to the frame 1 and can be connected to any of the fixed label receiving modules 3 to attach labels 5. The specific structure and working principle of the fixed label receiving modules 3 and the sliding label receiving modules 4 have been disclosed in the background technologies CN217918832U and CN115140593A, and will not be repeated here.

[0025] A label buffer device 6 for storing labels 5 is connected to the back of the frame 1. The label buffer device 6 includes a fixed roller group 602 and a sliding roller group 601 arranged at both ends of the frame 1 along its length. The sliding roller group 601 can move closer to or further away from the fixed roller group 602. Both the fixed roller group 602 and the sliding roller group 601 have several spaced-apart winding rollers 603 in the vertical direction. Specifically, the frame 1 has a belt group 7 arranged along the length of the frame 1 on the side near the label buffer device 6. The belt group 7 includes a motor-driven drive pulley 701, a driven pulley 702, and a belt 703 meshing with the drive pulley 701 and the driven pulley 702. The sliding roller group 601 has a mounting plate 704 bolted to the belt 703. The mounting plate 704 is bolted to either the upper or lower belt body of the belt 703. In this embodiment, the sliding roller group 601 is fastened to the upper belt body of the belt 703 by bolts through the mounting plate 704. When belt 703 rotates clockwise, sliding roller group 601 moves closer to fixed roller group 602; when belt 703 rotates counterclockwise, sliding roller group 601 moves further away from fixed roller group 602. Fixed roller group 602 has thirteen sets of winding rollers 603, and sliding roller group 601 has fourteen sets of winding rollers 603. Labels 5 from sliding label receiving module 4 are sequentially wound onto the winding rollers 603 of both fixed roller group 602 and sliding roller group 601. When sliding roller group 601 is at its furthest point, label buffer device 6 can store up to sixty meters of label 5, ensuring that the equipment can operate without stopping or slowing down during label receiving, maintaining normal operating speed.

[0026] To ensure the stability of the sliding roller group 601 during displacement, the frame 1 is also equipped with a slide rail 8, and both the fixed roller group 602 and the sliding roller group 601 are equipped with a sliding sleeve 9 that matches the slide rail 8. Specifically, there are two sets of slide rails 8, which are arranged at intervals in the vertical direction, and the sliding sleeves 9 on the fixed roller group 602 and the sliding roller group 601 are matched with the slide rails 8 one by one.

[0027] The top of the frame 1 is also equipped with a label-winding module 10 that moves synchronously with the sliding label-receiving module 4. The label-winding module 10 can receive the labels 5 from the sliding label-receiving module 4 and turn the labels 5 to ensure that the output direction of the labels 5 meets the requirements. Specifically, the label-winding module 10 includes a reversing roller 11 and a support roller 12. The reversing roller 11 is arranged at a 45° angle to the horizontal direction, and the support roller 12 is arranged at a 90° angle to the horizontal direction. The support roller 12 is located below the reversing roller 11. The labels 5 from the sliding label-receiving module 4 pass around the reversing roller 11 and are output from the gap between the reversing roller 11 and the support roller 12.

[0028] The working principle of this device is as follows: When automatic labeling is required, the label 5 no longer enters the label buffer device 6. The belt 703 rotates clockwise, and the sliding roller group 601 moves closer to the fixed roller group 602, releasing the stored label 5. The label 5 joint of the label roll 2 overlaps with the first label suction plate of the fixed label receiving module 3. Each fixed label receiving module 3 works in conjunction with the sliding label receiving module 4 to complete the labeling. After the labeling is completed, the belt 703 rotates counterclockwise, and the sliding roller group 601 moves away from the fixed roller group 602 to continue storing the label 5. Through the storage function of the label buffer device 6, the labeling process can be carried out at a speed of 250 meters per minute without stopping or slowing down, improving work efficiency. At the same time, the integrated mechanism occupies a small area and is easier to install.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
