[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0022] like Figure 1-Figure 5As shown, the present embodiment provides a vacuum roller with adjustable adsorption wrap angle, comprising a rotating outer cylinder 1, a fixed inner cylinder 2 is provided on the inner side of the rotating outer cylinder 1, a plurality of rows of vacuum ports 3 are provided on the side of the fixed inner cylinder 2 along its circumference, a sealing plate 4 is provided between two adjacent vacuum ports 3, an adjusting rotating cylinder 5 is provided on the inner side of the fixed inner cylinder 2, a single row of air ports 6 is provided on the side of the adjusting rotating cylinder 5, and a rotating rod 7 extending out of the fixed inner cylinder 2 is provided at one end of the adjusting rotating cylinder 5.

[0023] When the position of the adsorption wrap angle needs to be adjusted, the rotating rod 7 is rotated to align the air port 6 on the adjustment drum 5 with the vacuum port 3 at the required position to form a new vacuum area. There is no need to disassemble the vacuum roller, which simplifies the operation process and improves production efficiency.

[0024] In this embodiment, if Figure 3 As shown, six rows of vacuum ports 3 are provided, with five vacuum ports 3 in each row. The five vacuum ports 3 are evenly distributed along the length direction of the fixed inner cylinder 2, with multiple more adjustable areas, thereby improving the flexibility of the equipment.

[0025] In this embodiment, if Figure 2 As shown, a knob 8 is provided on the rotating rod 7, a key slot 9 is provided on the rotating rod 7, and a key 10 is provided on the knob 8 to be inserted into the key slot 9, so that the knob 8 can drive the adjusting drum 5 to rotate.

[0026] In this embodiment, if Figure 1 As shown, a knob limiting cylinder 11 is provided on the outer side of the rotating rod 7 on the fixed inner cylinder 2, and the bottom of the knob 8 is clamped in the knob limiting cylinder 11 to protect the knob 8 and prevent the knob 8 from falling off.

[0027] In this embodiment, if Figure 2 As shown, a spring 12 is provided on the inner bottom surface of the knob limiting cylinder 11, and a groove 13 is provided on the bottom surface of the knob 8. One end of the spring 12 is fixed on the inner bottom surface of the knob limiting cylinder 11, and the other end of the spring 12 is provided with a ring plate 14. The ring plate 14 is set in the groove 13. The spring 12 supports the position of the knob 8. When the knob 8 is rotated to drive the adjustment drum 5 to rotate, the groove 13 rotates relative to the ring plate 14, which will not affect the rotation of the adjustment drum 5.

[0028] In this embodiment, if Figure 3 and Figure 5As shown, the end surface of the knob 8 in contact with the knob limiting cylinder 11 is provided with a plurality of clips 15 along its circumference. The number and position of the clips 15 correspond one-to-one with the number and position of the sealing plates 4, and the air inlet 6 can be adjusted to a position completely corresponding to the vacuum port 3 to ensure the vacuum effect. The side of the knob limiting cylinder 11 in contact with the knob 8 is provided with a plurality of slots 16 for use with the clips 15 along its circumference. When adjusting the adsorption wrap angle position, press the knob 8 downward, the clips 15 will be disengaged from the slots 16, and can be rotated. After rotating to the desired position, release the knob 8 to allow the clips 15 to be stuck in the slots 16 to fix the position of the adjusting drum 5.

[0029] In this embodiment, if Figure 1 As shown, bearings 17 are provided at both ends of the rotating outer cylinder 1 to support the rotation of the rotating outer cylinder 1. The connectors, seals and other parts used between the rotating outer cylinder 1 and the fixed inner cylinder 2 are not changed in this application and conventional means can be used.

[0030] In summary, this embodiment achieves precise control of the suction wrap angle by providing multiple rows of vacuum ports 3 and sealing plates 4 on the exterior of a fixed inner cylinder 2 and arranging an adjustable rotating drum 5 with a single row of air ports 6 on the interior. Only the vacuum ports 3 corresponding to the air ports 6 can be vacuumed, thereby achieving a specific suction wrap angle. By adjusting the position of the air ports 6 on the adjustable rotating drum 5, the suction wrap angle can be easily changed to suit different production requirements without disassembling the vacuum roller, simplifying the operation process and improving production efficiency.
