[0020] 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.

[0021] like Figures 1-4 As shown, the vacuum roller that is easy to disassemble and install provided in this embodiment includes a vacuum roller body 1, and mounting inner tubes 2 are provided on both sides of the vacuum roller body 1. Special-shaped grooves 3 are provided on the mounting inner tubes 2, special-shaped blocks 4 are provided on both sides of the vacuum roller body 1, and a mounting outer tube 5 is provided on the outer side of the mounting inner tube 2. The mounting inner tube 2 can move forward and backward along the axial direction of the mounting outer tube 5, and a first fixing hole 6 and a second fixing hole 7 are provided on the mounting inner tube 2 and the mounting outer tube 5 respectively. Bolts 8 are provided in the first fixing hole 6 and the second fixing hole 7. When the mounting inner tube 2 extends outward, the two ends of the vacuum roller body 1 are clamped and fixed in the mounting inner tubes 2 on both sides through the cooperation of the special-shaped grooves 3 and the special-shaped blocks 4. The bolts 8 are then used to fix the positions of the mounting inner tube 2 and the mounting outer tube 5, so that the installation of the vacuum roller body 1 can be realized. When the mounting inner tube 2 moves inward, the two ends of the vacuum roller body 1 lose support and can be easily removed.

[0022] In this embodiment, if Figure 1As shown, a flange 9 is provided on the outer side of the mounting outer tube 5, and the mounting outer tube 5 is mounted at the desired position through the flange 9, and the connection is stable. During the subsequent disassembly and installation of the vacuum roller body 1, there is no need to disassemble the flange 9, so that the mounting outer tube 5 is always in the same position.

[0023] In this embodiment, if Figure 2 As shown, a spring 10 is provided between the bottom surface of the inner tube 2 and the inner bottom surface of the outer tube 5, which provides support and shock absorption for the inner tube 2 to ensure structural stability.

[0024] In this embodiment, if Figure 2 As shown, a telescopic rod 11 is provided in the spring 10, and the two ends of the telescopic rod 11 are respectively connected to the bottom surface of the inner tube 2 and the inner bottom surface of the outer tube 5, providing greater supporting force and ensuring that the inner tube 2 does not deviate from the axial movement of the outer tube 5.

[0025] In this embodiment, if Figure 2 As shown, the first fixing hole 6 is set on the bottom plate of the inner tube 2. The first fixing hole 6 passes through the bottom plate of the inner tube 2 along the radial direction of the inner tube 2. A longer bolt 8 is used to pass through the inner tube 2 and the outer tube 5, which is more convenient during disassembly.

[0026] In this embodiment, if Figure 2 As shown, a bolt tightening auxiliary block 12 is provided on the outer side of the second fixing hole 7 on the mounting outer tube 5 to increase the contact area with the bottom surface of the head of the bolt 8 and the nut, so that the bolt 8 is connected more tightly.

[0027] In this embodiment, if Figure 3 and Figure 4 As shown, the inner side of the special-shaped groove 3 is a circular groove, the outer side of the special-shaped groove 3 is a hexagonal groove, the inner side of the special-shaped block 4 is a circular block, and the outer side of the special-shaped block 4 is a hexagonal block, which prevents the vacuum roller body 1 and the mounting inner tube 2 from rotating relative to each other.

[0028] To sum up, in this embodiment, an inner tube 2 and an outer tube 5 are provided on both sides of the vacuum roller body 1. When the inner tube 2 is extended outward, the two ends of the vacuum roller body 1 are clamped and fixed. When the inner tube 2 is moved inward, the two ends of the vacuum roller body 1 lose support and are disassembled. When the vacuum roller body 1 needs to be cleaned or replaced, time can be greatly saved and work efficiency can be improved.

[0029] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
