[0002] The shaving machine is a piece of equipment used in the leather industry. It is used to shave bare leather, wet leather or semi-dry leather to achieve the required thickness. In actual use, the knife sharpening of the domestic shaving machine will not stop when the leather enters. Endless sharpening wastes a lot of knives, grinding wheels and blades each time. The sharpening time needs to be controlled by the knife roller sharpening control device of the shaving machine.

[0003] As disclosed in the utility model patent with publication number CN220388837U and name of a knife roller sharpening control device for a shaving machine, it includes a base, a support vertical plate and a horizontal top plate, a servo motor is installed at the top end of the base through an end plate A and bolts, the output shaft of the servo motor is connected to a screw rod and a screw block is sleeved on the screw rod, the top of the screw block is installed with a support vertical plate through bolts and a horizontal top plate is welded to one side of the top of the support vertical plate, an electric hydraulic cylinder is installed at the bottom end of the horizontal top plate through a mounting seat, the output shaft of the electric hydraulic cylinder is connected to a support spring through a fixing plate and a grinding disc is installed at the bottom of the support spring through bolts, and a hanging plate is provided on one side of the support vertical plate.

[0004] When this device is actually used, the shaving machine will generate a large amount of waste beard when processing leather, which will affect the reciprocating grinding movement of the grinding disc on the knife roller. In addition, the continuous contact between the grinding disc and the knife roller during continuous grinding will further affect the movement of the grinding disc and reduce the grinding effect of the knife roller. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a grinding device for a knife roller of a shaving machine, which is used to solve the technical problem in the background technology that the grinding device for the knife roller of a shaving machine is difficult to move and grind smoothly.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A grinding device for a shaving machine blade roller comprises a machine body, a conical guide rail is fixedly provided on the machine body, a grinding frame is slidably provided on the conical guide rail, a driving component for driving the grinding frame to move on the conical guide rail is provided on the machine body, a grinding disc is adjustably provided on the grinding frame, and a plurality of lubrication components connected to the conical guide rail are also provided on the grinding frame.

[0008] Working principle:

[0009] The device is a knife roller grinding device for a shaving machine, which is mainly used to be installed on the body of the shaving machine and to grind the knife roller of the shaving machine, so as to improve the processing effect of the shaving machine on the cloth.

The driving assembly drives the grinding frame to move back and forth on the conical guide rail, and the grinding disc performs a reciprocating grinding operation on the knife roller. When the grinding frame moves, the lubrication assembly lubricates the grinding frame and the conical guide rail.

[0011] Beneficial effects obtained:

[0012] First, the tapered guide rail can effectively prevent the waste generated by the processed leather from staying on its surface due to its shape, making it easier for the grinding frame to slide on the tapered guide rail.

[0013] Secondly, a driving assembly is provided, which can effectively drive the grinding frame and the grinding disc to move on the tapered guide rail, so as to facilitate the reciprocating grinding of the grinding disc on the knife roller.
