DETAILED DESCRIPTION

[0021] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0023] As Figures 1-3 shown, the present application provides a compression roller replacement structure, which comprises a printing device mounting plate 1, two groups of printing device supports 101 are fixedly installed on the printing device mounting plate 1, and annular supporting plates 102 are fixedly installed on the printing device supports 101, the annular supporting plates 102 are used for supporting the compression roller;

[0024] The compression roller assembly 2 is supported and placed between the two groups of annular supporting plates 102, the compression roller assembly 2 comprises a roller cylinder 201 placed between the two groups of annular supporting plates 102, and the roller cylinder 201 has a roller shaft 202;

[0025] The bearing seats 203 are sleeved and installed at both ends of the roller shaft 202, the roller shaft 202 is placed between the two groups of annular supporting plates 102 through the bearing seats 203, the sleeve 204 is fixedly installed at both ends of the roller shaft 202, and the sleeve 204 has an irregular slot inside;

[0026] The fixing assembly 3 is installed on the printing device mounting plate 1, and is used for clamping the compression roller. The fixing assembly 3 comprises two sets of fixing frames 301 fixedly installed on the printing device mounting plate 1, and the fixing frames 301 are fixedly installed with plug blocks 302, which are adapted to be matched with the plug slots, so as to preliminarily fix the two ends of the compression roller.

[0027] The fixing frames 301 are installed with clamping units, which comprise support frames 303 fixedly installed on the fixing frames 301, and the support frames 303 are fixedly installed with sliding rods 304 in T-shaped structure. The sliding rods 304 are fixedly installed with fixed seats 305 at one end, and the fixed seats 305 are threadedly connected with bidirectional screw rods 306, which have bidirectional screw grooves (not marked in the figure).

[0028] The bidirectional screw rods 306 are threadedly connected with two sets of sliding blocks 307, and the sliding blocks 307 are fixedly installed with oppositely arranged clamping half-rings 308, which are adapted to wrap the sleeve 204. The sliding blocks 307 are adapted to move close to or away from each other with the rotation of the bidirectional screw rods 306, so that the clamping half-rings 308 are adapted to synchronously slide with the sliding blocks 307 to clamp the sleeve 204, thereby fixing the compression roller.

[0029] The bidirectional screw rods 306 are fixedly installed with handles at one end, which facilitate the rotation of the bidirectional screw rods 306 to drive the two sets of sliding blocks 307 to rotate.

[0030] Working principle:

[0031] When the compression roller is damaged and needs to be replaced after long-term use, the handles are held and the bidirectional screw rods 306 are rotated to drive the two sets of sliding blocks 307 to move away from each other, thereby driving the two sets of clamping half-rings 308 to move away from each other, so that the two ends of the compression roller are no longer clamped. This fixing method is relatively convenient to disassemble compared with the above-mentioned patent through bearing connection, and is convenient for disassembling the compression roller.

[0032] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
