Specific embodiment

As shown in figs. 1-7, a kind of knife sharpening device of adjustable angle, including the first parts 5 are arranged on first parts 5 There is the rectangular notch for arrangement of tool 2,5 upper end of the first parts is fixed with the first connector 14, first connector Tapped through hole is provided on 14, first connector 14 drives axle thread by the tapped through hole and the first stepper motor 12 Connection, 5 upper end of the first parts is located at the rectangular notch two sides and is respectively and fixedly provided with knife rest 4, the company of being respectively and fixedly provided on the knife rest 4 Spindle, is respectively and fixedly provided with blade grinder 3 in the connecting shaft, two blade grinders 3 and the cutter 2 cloth at an angle It sets；First parts, 5 lower end is fixed with the second parts 7 and third parts 6, sets among second parts 7 and third parts 6 The 4th parts 8 are equipped with, the 4th parts 8 are to be slidably matched with second parts 7 and third parts 6, the 4th parts 8 Bottom end is fixed with sliding block 9, and 9 lower end of sliding block is provided with slideway 10, and the slideway 10 is fixed on station 11；Described 4th 8 bottom end of parts is further fixed on connecting lever 16, and the second connector 15 is fixed on the connecting lever 16, is arranged on second connector 15 There is tapped through hole, second connector 15 is threadedly coupled by tapped through hole with the drive shaft of second stepper motor 13.

First stepper motor 12 is fixed on station 11, and first stepper motor 12 passes through PLC controller control Make its positive and negative rotation and velocity of rotation.

The second stepper motor 13 is fixed on station 11, and the second stepper motor 13 passes through PLC controller control Make its positive and negative rotation and velocity of rotation.

The action process of the utility model is as follows:

Cutter 2 cut paper products 1 during, cutter 2 is driven by driving mechanism, in vertical direction on move down It is dynamic, so that sliding friction occurs with the blade grinder 3 being fixed on knife rest 4, to realize the purpose of polishing.

Adjust one: during cutter 2 cuts paper product 1, cutter 2 understands gradually rust, is at this moment controlled by PLC controller The first stepper motor 12 drive shaft forward or reverse and its velocity of rotation, the mode being threaded into, which pushes, is fixed on First connector 14 of one parts, 5 upper end is mobile and then drives the third parts 6 and the second parts for being fixed on 1 lower end of the first parts 7 with the 4th parts 8 occur it is opposite slide, to realize the rotation of the first parts 5 in the horizontal plane, thus make blade grinder 3 with Angle between cutter 2 changes, and realizes the repairing of sharpening angle.

Adjust two: during cutter 2 cuts paper product 1, under long-time, cutter 2 can be become narrow gradually, at this moment by PLC The drive shaft of controller second stepper motor 13 is forward or reverse and its velocity of rotation, the mode being threaded into pass through drive The mobile drive in turn of connecting lever 16 for being fixed on 8 lower end of the 4th parts is fixed on the sliding block 9 of 8 lower end of the 4th parts along 10 front and back of slideway Sliding to realize the back-and-forth motion of the 4th parts 8 in the plane, and then drives and is fixed on third parts 6 and the second parts 7 The first parts 5 be moved forward and backward in the plane, to make the distance between blade grinder 3 and cutter 2 change, to realize The width of sharpening is repaired.

In real work, adjusting one and adjusting two to carry out simultaneously.

Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model Range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are practical new to this The various changes and improvements that the technical solution of type is made should all fall into the protection scope that the utility model claims book determines It is interior.
