Description

Technical Field

[0001] This utility model belongs to the field of printing roller processing technology, and in particular relates to a shaft-driven printing roller clamping structure for a cleaning machine. Background Technology

[0002] The main body of a gravure printing roller is generally a cylindrical steel tube. Before engraving images, the surface of the gravure printing roller needs to be cleaned by a cleaning machine to prevent impurities from affecting subsequent processes such as chrome plating and polishing. Furthermore, the roller needs to be cleaned again after engraving. Some existing cleaning machines have drive shafts and center limiting holes on both sides. Conical dead centers are mounted on the drive shafts, and conical live centers are inserted into the center limiting holes to hold the roller in place for rotational cleaning. However, this type of cleaning machine can only be used to clean non-shafted rollers. For shafted rollers, the inability to hold them in place prevents cleaning. Therefore, a shafted roller holding structure needs to be invented for cleaning machines. Utility Model Content

[0003] The purpose of this invention is to provide a shafted roller clamping structure for a cleaning machine, which solves the problem that some existing cleaning machines cannot fix the shafted roller.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A clamping structure for a shafted printing roller in a cleaning machine includes a printing roller bushing detachably and fixedly connected to the drive shaft of the cleaning machine. The printing roller bushing is used to limit the first shaft of the shafted printing roller. A rotating center is inserted into a center limiting hole of the cleaning machine, and the head of the rotating center is used to insert into the shaft hole of the second shaft of the shafted printing roller. A limiting hole is provided on the side of the printing roller bushing facing the first shaft, allowing the first shaft to be inserted. A connecting hole is provided on the side of the printing roller bushing facing the drive shaft, allowing the drive shaft to be inserted.

[0006] Preferably, in combination with the above scheme, the limiting hole and the connecting hole are coaxially arranged.

[0007] Preferably, in conjunction with the above scheme, the limiting hole is a conical hole, the diameter of which gradually increases from the inside to the outside.

[0008] Preferably, in conjunction with the above scheme, a fixing part is provided between the limiting hole and the connecting hole, and the fixing part is used to connect with the drive shaft.

[0009] Preferably, in conjunction with the above scheme, the fixing part is provided with a fixing hole, which is used for detachable and fixed connection with the drive shaft by screws.

[0010] Preferably, in conjunction with the above scheme, the fixing hole is a T-shaped hole.

[0011] Preferably, in conjunction with the above scheme, the outer contour of the printing roller bushing is a cylindrical structure.

[0012] The beneficial effects of this utility model are as follows: Using the shafted roller clamping structure of this utility model for cleaning machines, the corresponding model of adjusting bushing can be selected according to the different shaft diameters of the shafted roller. Furthermore, the clamping of the center sleeve body and the adjusting bushing can be finely adjusted by tightening the adjusting bolts. Only inexpensive adjusting bushings of different models need to be manufactured, eliminating the need to replace the more expensive center sleeve body, thus reducing production costs.

[0013] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0020] Figure 7 This is a diagram showing the fit between the second shaft, the center limiting hole, and the rotating center in this utility model. Detailed Implementation

[0021] like Figure 1 and Figure 2 The existing cleaning machine shown has a conical dead center 20 detachably fixed to the drive shaft 4 on the left by screwing, and a conical live center 30 inserted into the center limiting hole 5 of the moving mechanism on the right. This structure can only be used to clamp and fix the hollow printing roller 10 without a shaft, but cannot be used to fix the printing roller 3 with a shaft and perform rotation cleaning.

[0022] like Figures 3 to 7As shown, this utility model provides a new clamping structure for a shafted printing roller in a cleaning machine. A printing roller sleeve 1 is detachably and fixedly connected to the drive shaft 4 of the cleaning machine. The printing roller sleeve 1 is used to limit the first shaft 31 of the shafted printing roller 3. A rotating tip 2 is inserted into the tip limiting hole 5 of the cleaning machine. The rotating tip 2 is a standard part with a bearing inside and its conical head is rotatable. The head of the rotating tip 2 is used to insert into the shaft hole 321 of the second shaft 32 of the shafted printing roller 3. A limiting hole 11 is provided on the side of the printing roller sleeve 1 facing the first shaft 31, and the limiting hole 11 is used to allow the first shaft 31 to be inserted. A connecting hole 12 is provided on the side of the printing roller sleeve 1 facing the drive shaft 4, and the connecting hole 12 is used to allow the drive shaft 4 to be inserted.

[0023] To make the rotation of the roller driven by the drive shaft 4 more stable, the limiting hole 11 and the connecting hole 12 are coaxially arranged.

[0024] Since the shaft diameters of different models of shafted rollers 3 are different, in order to adapt to the first shaft 31 with different diameters, the limiting hole 11 is a conical hole with its diameter gradually increasing from the inside to the outside.

[0025] To facilitate the drilling of screw holes and their connection and fixation to the drive shaft 4, a fixing part 13 is provided between the limiting hole 11 and the connecting hole 12. The fixing part 13 is used to connect to the drive shaft 4.

[0026] To facilitate connection and fixation with the drive shaft 4 using screws, and to allow for the removal and replacement of other tips and printing roller bushings 1, the fixing part 13 is provided with fixing holes 14, which are used for detachable and fixed connection with the drive shaft 4 by screws 15.

[0027] To facilitate the installation and positioning of the screw 15, the fixing hole 14 is a T-shaped hole with a stepped surface.

[0028] For ease of processing, the outer contour of the printing roller bushing 1 is a cylindrical structure.

[0029] How to use this utility model:

[0030] When using this utility model to clean the shafted printing roller, first remove the conical dead center 20 and the conical live center 30 from the cleaning machine, and put the printing roller bushing 1 on the drive shaft 4 on the left side of the cleaning machine. Screw 15 into the fixing hole 14 and the threaded hole 41 of the drive shaft 4 to fix the printing roller bushing 1 and the drive shaft 4. Then, install the rotating center 2 into the center limiting hole 5 on the right side of the cleaning machine. Then, align the first shaft 31 on the left side of the shafted printing roller 3 with the limiting hole 11 inserted into the printing roller bushing 1 to complete the left side limiting. Start the moving mechanism of the cleaning machine to drive the rotating center 2 to move to the left. The conical head of the rotating center 2 enters the shaft hole 321 of the second shaft 32 on the right side to complete the right side limiting, thereby pressing against the left and right ends of the shafted printing roller 3. Then, start the cleaning machine motor to drive the shafted printing roller 3 to rotate and clean.
