[0002] Compressed towels are easy to carry and store, typically made by compressing regular towels. They expand in contact with water while remaining intact, making them convenient to use. Compressed towels typically come in textures like mesh, pearl, and plain, with varying absorbency and abrasion resistance. When purchasing, choose the texture that best suits your needs. Compressed towels are generally disposable.

[0003] During the production process of compressed towels, it is usually necessary to first attach labels to the upper and lower surfaces of the cylindrical compressed towels, and then put a layer of film on the outside of the compressed towels with labels as a packaging structure.

The guide groove 8213 is an arc-shaped structure, and the number corresponds to the guide drive rod 824. The guide drive rod 824 moves inside the guide groove 8213.

[0055] See also Figure 13 The adsorption module 83 includes a motor mounting base 831 fixedly installed in the middle of the label storage module 82, and a workstation switching motor 834 is fixedly installed inside the motor mounting base 831. The end of the output spindle of the workstation switching motor 834 is fixedly connected to the cylinder mounting base 836, and two label picking cylinders 837 are symmetrically installed inside the cylinder mounting base 836.

The adsorption module 83 also includes a sensor mounting base 832 installed in the middle of the label storage module 82 and located on both sides of the motor mounting base 831. An infrared sensor 833 is fixedly installed at the end of each sensor mounting base 832, and a baffle 835 is provided on the external fixed sleeve of the output spindle of the workstation switching motor 834.

[0056] When the label paper is put on the tray 826, the distance between the trays 826 can be adjusted according to the diameter of the label paper. When adjusting, the knob 828 is rotated, and the knob 828 drives the second active tooth 829 to rotate, and the second active tooth 829 drives the second driven tooth 8212 to rotate. A guide driving rod 824 is inserted in the guide groove 8213 on the second driven tooth 8212, and the guide groove 8213 is arc-shaped. Therefore, when the guide groove 8213 rotates, it squeezes the guide driving rod 824, so that the slider 823 slides inside the slide groove 822, and the label paper limiting rod 825 and the tray 826 move as a whole, finally achieving the effect of the trays 826 moving closer or farther away synchronously. After the stacked label paper is placed, the trays 826 support it. When the label paper is blanked, the label taking cylinder 83 7 extends, pushing the suction cup 839 to move up. When the suction cup 839 contacts the bottom layer of label paper, the internal pressure of the air pipe 838 becomes negative, allowing the suction cup 839 to generate suction and absorb the bottom layer of label paper. Then the label picking cylinder 837 shortens and pulls the label paper downward, causing the label paper to be slightly light and pass over several trays 826. At this time, the label paper is unloaded. When a station absorbs label paper, the station switching motor 834 drives the cylinder mounting seat 836 to rotate. During the rotation process, the two infrared sensors 833 detect the baffle 835 and control the station switching motor 834 to stop and rotate 180 degrees. At this time, another station will reach the position of the previous station and repeat the above operation to absorb new label paper. After the label paper is absorbed, the elevator 81 drives the label storage module 82 and the adsorption module 83 to move downward synchronously. After the label paper contacts the surface of the compressed towel, the suction cup 839 releases the label paper, and the cycle is repeated.

[0057] See also Figure 14 The film heat shrink module 9 includes an outer protective cover 91 fixedly installed on the top of the equipment cabinet 1, and a film heat shrink gun 92 is fixedly installed on the side of the outer protective cover 91. The heat shrink nozzle of the film heat shrink gun 92 is located inside the outer protective cover 91. When each clamp 3 rotates with the turntable 2, it passes through the inside of the outer protective cover 91 and stops at the position of the heat shrink nozzle of the film heat shrink gun 92 for a certain period of time.

[0058] When the film heat shrink module 9 is working, the film heat shrink gun 92 generates high-temperature hot air and sprays it toward the compressed towel covered with the film. After being heated, the film shrinks, so that the film is wrapped around the outside of the compressed towel.

[0059] In summary, the fully automatic sleeve packaging machine, by respectively setting a turntable 2, a clamp 3, a feeder 4, a loading module 5, a sleeve film module 6, an upper label blanking module 8, a film heat shrink module 9, a unloading module 10 and a lower label blanking module 12, can cooperate and collaborate with each other, and automatically complete the work of attaching and removing labels and packaging sleeves of compressed towels. Compared with the manual labeling and sleeve wrapping method in the prior art, the efficiency is higher, can meet the needs of mass production, and has low production costs, and the yield rate is greatly improved compared with manual labor.
