[0020] The following is a combination of the appended examples of the present invention Figure 1-5 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] As shown in the figure, a suction roller of a labeling machine includes a roller body 1 and a rotating shaft 2, the rotating shaft 2 penetrates into the end of the roller body 1 and is fixedly connected to the roller body 1, the roller body 1 is provided with a plurality of air inlet holes 11 distributed side by side along the axial direction of the roller body 1, and an air outlet channel 21 is opened in the rotating shaft 2, a support plate 3 is fixedly connected to the roller body 1 and is located on one side of the end of the roller body 1, an air outlet chamber 4 connected to the air outlet channel 21 is formed between the support plate 3 and the inner wall of the roller body 1, a guide member 5 is fixedly connected to the support plate 3 and is located on the inner side of the air inlet hole 11 and parallel to the axial direction of the roller body 1, the guide member 5 has an opening facing the air inlet hole 11 and tightly connected to the inner wall of the roller body 1, so that a guide channel 6 connected to the air inlet hole 11 is formed between the guide member 5 and the inner wall of the roller body 1, and a guide port 51 connecting the guide channel 6 and the air outlet chamber 4 is opened at the end of the guide member 5.

[0022] The airflow from the roller body 1 is directed to the guide channel 6, which is formed between the guide member 5 and the inner wall of the roller body 1, thereby reducing the amount of air flowing out of the roller body 1 and the air inlet 21.

[0023] In addition, on the basis of the above structure, the support plates 3 are symmetrically arranged in two pieces in the roller body 1, so that two air outlet chambers 4 are formed in the roller body 1, respectively located at both ends of the roller body 1, and the two ends of the guide member 5 are fixedly connected to the two support plates 3, respectively. The air inlet holes 11 are symmetrically arranged in two rows on the roller body 1, and the guide members 5 are symmetrically arranged in two pieces in the roller body 1, so that two guide channels 6 corresponding to the two rows of air inlet holes 11 are formed in the roller body 1. The rotating shaft 2 is respectively at both ends of the roller body 1. There is one, and the guide port 51 is provided at each end of the guide member 5. The above structures are arranged in pairs, so that two air flow paths are formed in the roller body 1, with the starting points being two rows of air inlet holes 11 and the end points being the air outlet channels 21 in the two rotating shafts 2. After the two rotating shafts 2 are connected to the suction equipment, the two rows of air inlet holes 11 can be used to adsorb the material in contact with the outer wall of the roller body 1, thereby increasing the adsorption frequency of the material when the roller body 1 rotates, thereby enhancing the adsorption effect on the material.

[0024] In addition, based on the above structure, the guide member 5 is in the shape of a U-shaped plate, which reduces the resistance of the air flow when flowing in the guide channel 6, makes the air flow smoother and ensures the suction efficiency of the suction roller.

[0025] In addition, based on the above structure, the rotating shaft 2 passes through the support plate 3 and is fixedly connected to the support plate 3. The fixed connection between the rotating shaft 2, the roller body 1 and the support plate 3 is the same, so that the rotating shaft 2, the roller body 1 and the support plate 3 form a stable whole, ensuring the overall strength of the suction roller.

[0026] In addition, on the basis of the above structure, the air outlet chamber 4 is provided with a partition plate 7 which divides the air outlet chamber 4 into a first half chamber 41 and a second half chamber 42 which are not connected to each other. The first half chamber 41 and the second half chamber 42 are respectively connected to the two guide channels 6, and the two air outlet channels 21 are respectively connected to the first half chamber 41 and the second half chamber 42 on the corresponding side. Figure 2 As shown in the figure, the air outlet channel 21 on the left is connected to the second half cavity 42 on the left, and the air outlet channel 21 on the right is connected to the first half cavity 41 on the right, so that the two air flow paths with two rows of air inlet holes 11 as starting points and two air outlet channels 21 as end points are not connected to each other. When the suction roller is working, the air flows in the two air flow paths will not interfere with each other, thereby ensuring the stability and speed of the air flow, and then ensuring the suction efficiency of the suction roller.

[0027] In addition, on the basis of the above structure, a plurality of cleaning windows 11 connected to the air outlet chamber 4 are opened on the end face of the roller body 1, and a cover plate 13 for closing the cleaning window 11 is fixedly connected to the end face of the roller body 1. The cover plate 13 is detachably fixed to the end face of the roller body 1 by bolts. By removing the cover plate 13, the material debris sucked into the air inlet chamber during the operation of the suction roller can be cleaned through the cleaning window 11 to ensure the smoothness of the air flow during suction and the suction efficiency of the suction roller.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
