TECHNICAL FIELD
[0001] The utility model relates to the technical field of fur cutting, particularly to a fur cutting device with self-adaptive tensioning. BACKGROUND
[0002] In the fur processing industry, cutting is one of the core processes that determines the quality of finished products and material utilization. Traditional fur cutting mainly relies on manual operation combined with semi-automatic machinery. During operation, the raw hide or tanned leather is usually laid flat on the workbench, and the edge is fixed by mechanical clamps or pneumatic suction cups for multi-point fixation to expand the leather surface. Then, the worker holds the cutting tool or controls the numerical control cutting head to cut along the predetermined trajectory. However, the existing technology has several significant shortcomings in actual application. Most of the fixing devices use simple rigid clamping or constant air pressure suction, which cannot dynamically adjust according to the thickness, elasticity, and fiber direction of different areas of the leather. This leads to local stress concentration or relaxation wrinkles on the leather surface, especially when dealing with irregularly shaped or naturally textured leather. The cutting path is prone to deviation, resulting in size errors or uneven edges, causing waste of raw materials. Therefore, there is a need for a fur cutting device with self-adaptive tensioning. This device not only can clamp and fix different thickness of fur, but also can make the fur in a tight state according to the tensioning degree of the fur. However, it will not hard pull the fur, causing damage to the fur. At the same time, the device can cut and cut the fur to meet the various cutting requirements of the user. SUMMARY

An electric cylinder 103 is fixedly installed on the slider of the second lead screw moving mechanism 102, and the telescopic rod end of the electric cylinder 103 is fixedly connected to the cutting blade 104. Specifically, through one of the first lead screw moving mechanisms 101... The motor on the bracket drives the lead screw of the first lead screw moving mechanism 101 to rotate, which in turn drives the lead screw of the other first lead screw moving mechanism 101 to rotate, which in turn drives the sliders of the two first lead screw moving mechanisms 101 to move, further driving the second lead screw moving mechanism 102 to move back and forth, thereby driving the cutting blade 104 to move back and forth; the second lead screw moving mechanism 102 drives the electric cylinder 103 and the cutting blade 104 to move left and right, thus realizing multi-directional movement of the cutting blade 104 by using the two first lead screw moving mechanisms 101 and one second lead screw moving mechanism 102; the electric cylinder 103 extends and retracts to push the cutting blade 104 down, so that the cutting blade 104 can descend freely to cut.
[0034] In one optional embodiment of the present invention, such as Figures 4-7 As shown, the side compression fixing mechanism includes: a support rod 201, a rectangular plate 202, a spring 203, a grooved plate 204, and a connecting bracket 205; There are two support rods 201, each fixedly installed on the ground.

Specifically, by moving the rectangular plate 202, the spherical body on the rectangular plate 202 pushes or pulls one side of the channel plate 204, thereby causing the channel plate 204 to rotate, which in turn drives the connecting bracket 205 to rotate.

The upper top plate 207 is slidably mounted in the groove of the connecting bracket 205. Specifically, the small motor 209 drives the first cylindrical gear 210 to rotate, thereby driving the second cylindrical gear 211 to rotate, which in turn drives the two first swing rods 212 to swing, which in turn drives the two second swing rods 213 to swing, further driving the upper top plate 207 to move up and down in the groove of the connecting bracket 205.
[0038] In one optional embodiment of the present invention, such as Figure 11 As shown, the fixed fur part 2 also includes: a third lead screw moving mechanism 217, an arc-shaped base plate 221, a third cylindrical gear 222, and a lifting mechanism; There are two third lead screw moving mechanisms 217.

[0040] In one optional embodiment of the present invention, such as Figure 12 , Figure 13 As shown, the fixed fur part 2 also includes: a first spur rack 223, a fourth cylindrical gear 224, a fifth cylindrical gear 225, a second spur rack 226, a connecting rectangular plate 227, a side support plate 228, a third spur rack 229, and a supporting base plate 230.

[0041] Working principle: This equipment can keep the fur taut according to its tension, but will not pull it hard and cause damage. At the same time, this equipment can cut and trim the fur and meet the user's various trimming requirements. The fur to be processed is placed manually between the upper plate 207 and the lower plate 208. A small motor 209 drives the first cylindrical gear 210 to rotate, which in turn drives the second cylindrical gear 211 to rotate, which in turn drives the two first swing rods 212 to swing, which in turn drives the two second swing rods 213 to swing. This further drives the upper plate 207 to move up and down in the groove of the connecting bracket 205. As the upper plate 207 descends, it clamps one end of the fur. The trapezoidal protrusions on the upper plate 207 and the lower plate 208 are not too sharp and will damage the fur, while increasing the friction on the fur end to prevent the fur from shifting during the cutting process. The motor on one of the third lead screw moving mechanisms 217 drives the lead screw of the third lead screw moving mechanism 217 to rotate, thereby driving the lead screws of the two third lead screw moving mechanisms 217 to rotate, further driving the sliders on the two third lead screw moving mechanisms 217 to move, thereby driving the four U-shaped plates 218 to move respectively, further driving the first rectangular support plate 219 and the second rectangular support plate 220 to rotate, thereby pushing the arc-shaped base plate 221 to move up and down. When the fur is too long, the arc-shaped base plate 221 is used to lift the middle part of the fur, which can not only make the fur completely laid on the equipment, but also make the fur taut according to the tension of the fur, so as to facilitate cutting. The third lead screw moving mechanism 217 drives the third cylindrical gear 222 to rotate, which in turn drives the first spur rack 223 to move, thereby driving the third spur rack 229 to move, further driving the fourth cylindrical gear 224 to rotate, thereby driving the fifth cylindrical gear 225 to rotate, which in turn drives the two second spur racks 226 to move, thereby driving the two connecting rectangular plates 227 to move in opposite directions; further, it drives the two triangular support plates 215 connected to the same side of each connecting rectangular plate 227 to move, thereby driving the multiple rectangular plates 202 to move; By moving the rectangular plate 202, the spherical object on the rectangular plate 202 pushes or pulls one side of the grooved plate 204, thereby causing the grooved plate 204 to rotate, which in turn drives the connecting bracket 205 to rotate. As the arc-shaped base plate 221 is raised, the two ends of the fur rotate outward continuously. This allows the fur to be spread out flat, and the arc-shaped base plate 221 will not push up the middle of the fur, causing the two ends of the fur to bend and affecting the quality of the fur. The motor on the bracket of one of the first lead screw moving mechanisms 101 drives the lead screw of the first lead screw moving mechanism 101 to rotate, thereby driving the lead screw of the other first lead screw moving mechanism 101 to rotate, thereby driving the sliders of the two first lead screw moving mechanisms 101 to move, further driving the second lead screw moving mechanism 102 to move back and forth, thereby driving the cutting blade 104 to move back and forth; the second lead screw moving mechanism 102 drives the electric cylinder 103 and the cutting blade 104 to move left and right, thereby achieving multi-directional movement of the cutting blade 104 by using the two first lead screw moving mechanisms 101 and one second lead screw moving mechanism 102; the electric cylinder 103 extends and retracts to push the cutting blade 104 down, thereby allowing the cutting blade 104 to descend freely for cutting.
