Specific embodiments

[0025] The specific embodiments described herein are intended to be illustrative only and are not intended to limit the present application. Numerous variations and modifications will become apparent to those skilled in the art in view of the foregoing description.

[0026] In the present application, unless otherwise stated, the orientation words contained in the terms such as "up, down, inner, outer" only represent the orientation of the terms in the normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation on the terms.

[0027] As Figures 1-5 shown, a PVC decorative film embossing roller mounting structure comprises: a limit ring 1 coaxially fixedly assembled on the end part of the embossing roller, a bearing 2 with an inner diameter greater than the diameter of the end part of the embossing roller, a plurality of arc-shaped gaskets 3 arranged at intervals along the axial direction and capable of contacting the inner ring of the bearing 2, and a pressing unit 4 detachably assembled on the end part of the embossing roller.

[0028] The end of the arc-shaped gasket 3 protrudes from the limiting ring 1 and is provided with a flange part 4 which can contact the inner ring end of the bearing 2. The inner wall of the arc-shaped gasket 3 is gradually inclined to the axis of the compression ring roller in the direction close to the limiting ring 1 to form a first inclined wall. The compression unit comprises a positioning sleeve 5 which is detachably sleeved on the outer side of the end of the embossing roller and can move close to the limiting ring 1. The outer wall of the positioning sleeve 5 is a second inclined wall which matches the first inclined wall. The bearing 2 is located between the limiting ring 1 and the flange part 4.

[0029] When the embossing roller needs to be replaced, the compression unit is detached from the end of the embossing roller. After the positioning sleeve 5 is detached, the arc-shaped gasket 3 loses the support of the positioning sleeve 5 and can be detached from the inner side of the inner ring of the bearing 2, so that the bearing 2 can be detached. The limiting ring 1 is fixedly assembled on the end of the commonly used embossing roller, so that the limiting ring 1 does not need to be detached, the working efficiency of replacing the embossing roller can be improved. When the bearing 2 is assembled again, the bearing 2 is sleeved on the end of the embossing roller, the arc-shaped gasket 3 is inserted into the inner ring of the bearing 2, and the compression unit is assembled on the end of the embossing roller. The positioning sleeve 5 is sleeved on the outer side of the embossing roller. When the positioning sleeve 5 moves close to the limiting ring 1, the second inclined wall gradually matches the first inclined wall, so that the arc-shaped gasket 3 matches the inner ring of the bearing 2 to support the bearing 2. The bearing 2 and the end of the embossing roller are coaxial, and the limiting ring 1 and the flange part 4 clamp the inner ring of the bearing 2.

[0030] Through the above-mentioned way of detaching and assembling the bearing 2, the operation is simple and convenient, the damage to the bearing 2 is minimized, and the installation precision of the bearing 2 is high, so that the embossing depth can be accurately controlled.

[0031] The compression unit further comprises an installation cylinder 6 which is fixedly connected with the positioning sleeve 5 in the coaxial direction of the opening end, and a first installation bolt 7 which can pass through the end of the installation cylinder 6 and whose head can abut against the outer wall of the installation cylinder 6. The end face of the end of the embossing roller is recessed and provided with a threaded hole 8 which matches the first installation bolt 7.

[0032] By loosening the first installation bolt 7, the installation cylinder 6 and the positioning sleeve 5 can be detached. When assembling, the first installation bolt 7 is connected with the threaded hole 8 by passing through the installation cylinder 6, and the positioning sleeve 5 is pushed to move close to the limiting ring 1 by continuously rotating the first installation bolt 7. The first installation bolt 7 can universally position the installation of the positioning sleeve 5, which reduces the difficulty of assembly and disassembly and improves the working efficiency when replacing the embossing roller.

[0033] The compression unit further comprises at least one disassembly bolt 9 which can abut against the end face of the end of the compression ring roller. The end of the installation cylinder 6 is provided with a threaded through hole 10 through which the disassembly bolt 9 passes.

[0034] When the bearing 2 is disassembled, the positioning sleeve 5 is tightly inserted between the arc-shaped gaskets 3, and the disassembly bolt 9 is assembled on the threaded hole 10, and the disassembly bolt 9 is continuously rotated, after the end of the disassembly bolt 9 abuts against the end of the embossing roller, the installation cylinder 6 and the positioning sleeve 5 are continuously moved away from the limiting ring 1, the disassembly difficulty is further reduced by the disassembly bolt 9, and the work efficiency is improved.

[0035] The outer wall of the installation cylinder 6 is provided with a threaded part 11 matched with the disassembly bolt 9.

[0036] When assembled, the disassembly bolt 9 affects the rotation of the first installation bolt 7 driven by the tool, so the disassembly bolt 9 is disassembled from the threaded hole 10 and assembled on the threaded part 11, which facilitates the rotation of the first installation bolt 7 and prevents the disassembly bolt 9 from being lost.

[0037] The second inclined wall of the positioning sleeve 5 is provided with a plurality of strip-shaped grooves 12 penetratingly arranged in the circumferential direction and communicated with the inside, and the end of the strip-shaped groove 12 close to the limiting ring 1 is an open end.

[0038] The part of the positioning sleeve 5 between the adjacent two strip-shaped grooves 12 forms an elastic arm, and the elastic arm is tightly attached to the outer wall of the end of the embossing roller after being extruded by the arc-shaped gasket 3, so that the assembly precision of the bearing 2 is further improved.

[0039] The limiting ring 1 is threadedly connected with at least one second installation bolt 13, and the end side wall of the embossing roller is recessed to form a positioning groove for inserting the end of the corresponding second bolt.

[0040] The outer wall of the installation cylinder 6 is provided with at least one reinforcing rib 14.

[0041] The preferred embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the specific details in the above embodiments, and various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0042] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present application will not further describe various possible combination manners.

[0043] In addition, various different embodiments of the present application can be combined arbitrarily, as long as they do not violate the spirit of the present application, and should be considered as disclosed by the present application.
