[0001] The invention relates to the technical field of cutting equipment, and in particular to a cutting equipment for cold-proof composite fabrics with good cutting effect. Background Art

[0002] With the continuous development of society and the continuous advancement of science and technology, the technology related to cutting equipment is also constantly improving. Fabrics are materials used to make clothing. Fabrics can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. At present, cold-proof composite fabrics are deeply loved by people. In the process of production and processing, cold-proof composite fabrics need to be cut by cutting equipment.

[0003] The currently used cutting equipment cannot smooth the cold-proof composite fabrics on both sides of the cutting knife when cutting the cold-proof composite fabrics. When the cutting knife cuts the cold-proof composite fabrics, the cold-proof composite fabrics are easily wrinkled due to movement, which leads to uneven cutting of the fabrics, poor cutting effect of the cold-proof composite fabrics, and is not conducive to the use of the cutting equipment. Summary of the invention

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art: the cutting equipment currently used cannot smooth the cold-proof composite fabrics on both sides of the cutting knife when cutting the cold-proof composite fabrics. When the cutting knife cuts the cold-proof composite fabrics, the cold-proof composite fabrics are easily wrinkled due to movement, which leads to uneven cutting of the fabrics, poor cutting effect of the cold-proof composite fabrics, and is not conducive to the use of the cutting equipment. A cutting equipment for cold-proof composite fabrics with good cutting effect is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cutting device for cold-proof composite fabrics with good cutting effect, comprising a support platform, a bracket fixedly connected to the support platform, a placement seat slidably connected to the bracket, a rotating rod connected to the placement seat via a torsion spring, and a bearing plate fixedly connected to the rotating rod;

[0007] Two hydraulic cylinders are fixedly installed on the bracket, and the driving ends of the two hydraulic cylinders are fixedly connected to a cross, and a cutting knife is fixedly connected inside the cross. Two sliding openings are provided on the cross, and an I-shaped block is slidably arranged in each of the sliding openings. A T-shaped frame is connected to the I-shaped block through a first spring, and a pressing wheel is rotatably arranged on the T-shaped frame;

After the cross plate moves up with the T-shaped frame, it will be completely located above the upper end surface of the L-shaped plate. Under the elastic force of the second spring, the pull rod will slide relative to the cross, thereby driving the I-shaped block and the T-shaped frame to move along the sliding mouth. The two pressing wheels will roll against the fabric at the same time, and the distance between the two pressing wheels will increase, so that the fabric can be smoothed. After that, the cutting knife can move down to cut the smoothed fabric, avoiding uneven cutting of the fabric. The cutting effect of cold-proof composite fabric is better, which is conducive to the use of cutting equipment;

[0020] 2.

After the loading plate rotates with the rotating rod, it will change from a horizontal state to a tilted downward state, so that the fabric above the loading plate can slide down to the storage box for collection under the action of gravity. There is no need to manually remove the cut fabric, the operation is relatively simple and quick, and it is conducive to the use of the cutting equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] A limit assembly is fixedly installed on the cross 9, and the limit assembly includes two L-shaped plates 30 fixedly installed on the upper surface of the cross 9, and the upper end of each T-shaped frame 19 is fixedly connected to a horizontal plate 28, and the horizontal plate 28 is provided with a through hole for connecting the L-shaped plate 30. Two pull rods 29 are connected to the cross 9 through two second springs 31, and each T-shaped frame 19 is provided with a vertical groove 26. One end of each pull rod 29 is slidably connected to the corresponding vertical groove 26, and one side of each horizontal plate 28 is fixedly connected to a mounting rod 12 with an L-shaped cross-section. The two mounting rods 12 are symmetrically arranged, and the two mounting rods 12 are used to facilitate manual control of the movement of the two horizontal plates 28 at the same time, so as to reinsert one end of each L-shaped plate 30 into the through hole.

[0033] A slot is provided on the support platform 1, in which a support block 14 is slidably connected, the upper surface of the support block 14 is fixedly connected to the bearing plate 8, two symmetrically arranged fixing bars 16 are fixedly connected to the bracket 3, a storage box 2 is provided on one side of the support platform 1, a reciprocating screw 15 is rotatably connected to the bracket 3, a guide rod 20 is fixedly connected to the bracket 3, a placement seat 6 is slidably connected to the guide rod 20, the placement seat 6 is threadedly connected to the reciprocating screw 15, a servo motor is fixedly installed on the bracket 3, and the driving end of the servo motor is fixedly connected to the reciprocating screw 15.

[0034] When the fabric is cut, the servo motor drives the reciprocating screw rod 15 to rotate, and the placement seat 6 will move along the reciprocating screw rod 15, and the support block 14 and the carrying plate 8 will move at the same time. When the support block 14 moves to the outside of the support platform 1, the placement seat 6 continues to move in the same direction, and the concave-shaped rotating rod 24 will move against the two fixed bars 16, and the rotating rod 24 will rotate relative to the placement seat 6. Since one end of the torsion spring 25 is fixedly connected to the rotating rod 24 and the other end is fixedly connected to the placement seat 6, the torsion spring 25 is deformed, and the carrying plate 8 rotates with the rotating rod 24 and then changes from a horizontal state to a tilted downward state, so that the cloth above the carrying plate 8 can slide down to the inside of the storage box 2 under the action of gravity for collection, and there is no need to manually remove the cut fabric. The operation is relatively simple and quick, which is conducive to the use of the cutting equipment.

[0035] A limiting strip 7 with a T-shaped cross section is slidably connected to the placement seat 6, and a third spring 5 is sleeved on the limiting strip 7. One end of the third spring 5 is fixedly connected to the limiting strip 7, and the other end of the third spring 5 is fixedly connected to the placement seat 6. A fastening pad 4 is fixedly connected to the lower surface of the limiting strip 7. The fastening pad 4 is made of rubber. When in use, the limiting strip 7 is first pulled upwards, and then one end of the cold-proof composite fabric is placed on the surface of the placement seat 6. Then, the external force applied to the limiting strip 7 is removed. Under the elastic force of the third spring 5, the limiting strip 7 will move vertically downward until the surface of the fastening pad 4 is in close contact with the surface of the cold-proof composite fabric, thereby achieving a compression and fixation of the cold-proof composite fabric.

[0036] Two rotating cylinders 18 are rotatably connected to the bracket 3, and the inner wall of each rotating cylinder 18 is fixedly connected with a compression spring 21, and one end of the compression spring 21 is fixedly connected with a fixing sleeve 17, and a winding roller is arranged between the two fixing sleeves 17, and a clamping groove 23 with an isosceles trapezoidal cross-section is provided in each fixing sleeve 17, and a rubber pad is fixedly connected to the inner wall of the clamping groove 23, and a plurality of limiting grooves 22 arranged in a ring array are provided on the inner wall of each rotating cylinder 18, and each fixing sleeve 17 is slidably connected to the corresponding limiting groove 22, and the winding roller with the cold-proof composite fabric wound up is respectively inserted into the corresponding clamping groove 23 at both ends, and is tightly attached to the rubber pad, and under the elastic force of the compression spring 21, the two fixing sleeves 17 can be firmly connected to the winding roller, and the limiting groove 22 can prevent the fixing sleeve 17 and the rotating cylinder 18 from rotating relative to each other.

[0037] In the present invention, when in use, first pull the limit strip 7 upwards, then place one end of the cold-proof composite fabric (not shown) on the surface of the placement seat 6, then remove the external force applied to the limit strip 7, and under the elastic force of the third spring 5, the limit strip 7 will move vertically downward until the surface of the fastening pad 4 is in close contact with the surface of the cold-proof composite fabric, thereby achieving the compression and fixation of the cold-proof composite fabric, and then the servo motor drives the reciprocating screw rod 15 to rotate, and the placement seat 6 will move along the reciprocating screw rod 15, and will pull the cold-proof composite fabric, causing the winding roller to rotate, and when the cold-proof composite fabric moves to the appropriate position, the servo motor stops running.

[0038] After that, the hydraulic cylinder 10 drives the cross 9 to move vertically downward, and the two pressing wheels 11 are located on both sides of the cutting knife 13. After the two pressing wheels 11 move downward with the cross 9, they will first contact the cold-proof composite fabric on the placement seat 6. Subsequently, the hydraulic cylinder 10 continues to drive the cross 9 to move downward, and the T-shaped frame 19 will slide relative to the I-shaped block 32. Since one end of the first spring 27 is fixedly connected to the I-shaped block 32 and the other end of the T-shaped frame 19 is fixedly connected, the first spring 27 is deformed, and one end of the pull rod 29 slides inside the vertical groove 26 at the same time. In the initial state, one end of each L-shaped plate 30 passes through the corresponding through-hole, and the horizontal plate 28 moves up with the T-shaped frame 19. It will be completely located above the upper end surface of the L-shaped plate 30. Since one end of each second spring 31 is fixedly connected to the pull rod 29, and the other end is fixedly connected to the cross 9, under the elastic force of the second spring 31, the pull rod 29 will slide relative to the cross 9, thereby driving the I-shaped block 32 and the T-shaped frame 19 to move along the slide, and the two pressing wheels 11 will roll along the fabric at the same time, and the distance between the two pressing wheels 11 will increase, so that the fabric can be smoothed, and then the cutting knife 13 can be moved down to cut the smoothed fabric, avoiding uneven cutting of the fabric, having a better cutting effect on the cold-proof composite fabric, and being conducive to the use of the cutting equipment.
