Detailed Description

The present utility model will be further described with reference to specific examples and fig. 1 to 7, but the present utility model is not limited to these examples.

The embodiment particularly provides a knife sharpening device of a cutting bed, which is used for grinding a cutting ring 3 and comprises a fixed knife rest 1, two groups of knife sharpening mechanisms 2 and a knife sharpening baffle 4. The fixed knife rest 1 is used for fixing a cutting ring 3, and two groups of knife sharpening mechanisms 2 and knife sharpening baffles 4 are fixed on a cutting bed. Wherein, sharpening mechanism 2 part is arranged in sharpening baffle 4, sharpens in sharpening baffle 4, and the piece that the sharpening process produced also piles up in sharpening baffle 4 prevents piece departure.

The two groups of sharpening mechanisms 2 are respectively positioned at two sides of the cutting ring 3, and further, the sharpening mechanisms 2 are provided with a power piece 21, a movable seat 22 and a sharpening piece 23. The power piece 21 is used for providing power; the movable seat 22 is fixedly connected with the power piece 21 and driven by the power piece 21; the knife sharpening piece 23 is rotatably arranged on the movable seat 22, moves along with the movable seat 22 and is movably abutted against the cutting ring 3; specifically, in this embodiment, the movable base 22 is provided with a motor 28, a mounting member 24 and a sharpening member 23, the motor 28 is used for driving the sharpening member 23 to rotate, and the sharpening member 23 is fixed on the motor 28 through the mounting member 24 and is driven by the motor 28.

When the knife sharpening device sharpens, the power piece 21 drives the movable seats 22 at two sides so that the knife sharpening pieces 23 rotating at two sides of the cutting ring 3 are abutted against the cutting ring 3. According to the design, the power piece 21 is arranged to drive the movable seat 22, so that the sharpening piece 23 on the movable seat 22 automatically sharpens, the sharpening piece 23 is ensured to be relatively sharp all the time, cloth scraps and the like are not attached to the surface, and the cloth cutting process is smooth. The design of the two sets of sharpening mechanisms allows the two sharpening pieces 23 to be respectively ground from both sides so that both sharp corners of the ring cutter 3 are uniformly ground.

Further, the sharpening mechanism 2 is provided with at least a sliding rail 25 which is arranged on the cutting bed; a sliding block 221 is fixed on the moving seat 22, and moves along the sliding rail 25; the driving member controls the sliding block 221 to move along the sliding rail 25, so that the moving seat 22 moves along with the sliding block and drives the sharpening member 23 on the moving seat 22 to abut against or be far away from the ring cutter 3. The moving seat 22 and the motion track of the knife sharpening piece 23 are fixed through the design of the sliding rail 25 and the sliding block 221, so that the knife sharpening piece 23 can cut according to the designed cutting direction and angle.

Further, in actual use, the power member 21 may be a spring assembly, which is connected to the slider 221, so that the slider 221 drives the movable seat 22 to move under the driving of the spring assembly and controls the knife sharpening member 23 on the movable seat 22 to abut against or be away from the ring knife 3.

Meanwhile, the sharpening mechanism 2 is provided with a limit switch 26 which is movably abutted with the movable seat 22; when the movable seat 22 abuts against the limit switch 26, the knife blade 23 is released from abutting against the ring blade 3. The maximum working stroke of the knife sharpening piece 23 is controlled by setting the limit switch 26, the working of the cutting ring 3 has certain requirements on the parameters of the cutting ring, when the cutting ring 3 is ground to a certain degree, the cutting work cannot be continued normally, and at the moment, the cutting ring needs to be replaced. When the movable seat 22 abuts against the limit switch 26, it indicates that the cutting ring 3 cannot continue to work, and at this time, the motor 28 should drive the sharpening member 23 to release the abutment with the cutting ring 3, so that the user should replace the cutting ring 3 to ensure that the cutting work is smoothly performed.

Specifically, the limit switch 26 is formed with an abutment groove 261; the movable seat 22 is provided with an abutting surface 222; when the movable seat 22 abuts against the limit switch 26, the abutment surface 222 abuts against the abutment groove 261. The knife sharpening piece 23 stops sharpening by arranging the abutting groove 261 to abut against the abutting surface 222 on the movable seat 22, and the matched motor 28 better prevents the knife sharpening piece 23 from continuously sharpening when the cutting ring 3 cannot meet the working requirement.

In this embodiment, the sharpening mechanism 2 further has a guiding oblique block 27 fixedly arranged on the cutting bed; the guide rail and the limit switch 26 are fixedly arranged on the guide inclined block 27; wherein the guiding inclined blocks 27 in the two groups of sharpening mechanisms 2 have a height difference. The design of the guiding bevel block 27 makes the knife sharpening piece 23 grind the side face of the cutting ring 3 when grinding the cutting ring 3, and the symmetrical design of the two sides makes the two side faces of the cutting ring 3 grind so that the cutting face of the cutting ring 3 presents a sharp shape similar to a triangle to make the cutting process smooth. Meanwhile, the design of the height difference also ensures that the clamping force of the sharpening piece 23 on the cutting ring 3 during the grinding can not influence the normal operation of the cutting ring 3.

Further, the sharpening mechanism 2 further has at least a mounting member 24 fixedly provided on the cutting bed for mounting the power member 21.

In addition, the upper end and the lower end of the fixed tool rest 1 are respectively provided with a first bump 11 and a second bump 12; a guide wheel III 13 is clamped between the first lug 11 and the second lug 12 and is used for driving the ring cutter 3 to move. In the present embodiment, the first bump 11 is provided with a first connection hole 111; the second bump 12 is provided with a second connecting hole 121; fixing a first guide wheel 14 on the first bump 11 through a first connecting hole 111 by a fastener, and fixing a second guide wheel 15 on the second bump 12 through a second connecting hole 121; the movement of the cutting ring 3 is stabilized by the first guide wheel 14, the second guide wheel 15 and the third guide wheel 13. And the first guide wheel 14 and the second guide wheel 15 are arranged on two sides of the cutting ring 3, and the first guide wheel 14, the third guide wheel 13 and the second guide wheel 15 are arranged from high to low, so that the movement of the cutting ring 3 is facilitated. The movement of the cutting ring 3 is described in detail in patent No. 202110459929.0, and will not be described in detail.

Further, a travel groove 41 is formed in the knife sharpening baffle 4; the mounting piece 24 on the movable seat 22 extends into the sharpening baffle 4 through the travel slot 41 and moves in the travel slot 41. The travel groove 41 cooperates with the limit switch 26 to control the travel of the sharpening piece 23.

The upper and lower ends of the sharpening baffle 4 are provided with avoiding grooves 42, and the width of the avoiding grooves is larger than that of the cutting ring 3. The cutting ring 3 can be inserted into the recess 42.

The above embodiments are only preferred embodiments of the present technical solution, and do not limit the protection scope of the present technical solution accordingly, so: all equivalent changes according to the structure, shape and principle of the present technical scheme should be covered in the protection scope of the present technical scheme.
