Description

Technical Field

[0001] The utility model belongs to the technical field of cloth-pulling and cutting machines, and more specifically, particularly relates to a central unwinding synchronous constant tension cloth-pulling and cutting machine. Background Art

[0002] A fabric cutting machine is a device used to cut textiles, cloth or other similar materials. It usually consists of a platform and a moving arm with a cutting knife. The operator places the material to be cut on the platform and then uses a control device to move the arm so that the cutting knife cuts the material. Fabric cutting machines are often used in industrial production to efficiently cut large quantities of textiles and improve production efficiency.

[0003] Because the cloth is subjected to external tension and is stretched before being cut, when the cutting knife of the cloth-pulling cutting machine cuts the cloth, the cloth will lose tension at the cut position, causing the internal stress of the cloth to be released, resulting in wrinkles appearing instantly at the cut position. Since the appearance of wrinkles will cause the cloth to deform at the same time, continuing to cut at this time may easily lead to uneven cutting position, affecting the quality of the product after cutting. In addition, some materials such as cotton and wool are prone to produce lint when cutting. These lints enter the machine parts and easily cause damage to the machine, affecting the service life of the cutting machine.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a center unwinding synchronous constant tension cloth cutting machine is provided, in order to achieve a more practical purpose. Utility Model Content

[0030] A bidirectional screw 14 is rotatably installed in the second slide groove 11 , and the bidirectional screw 14 passes through the upper and lower ends of a pair of L-shaped clamping plates 12 and is threadedly connected with the L-shaped clamping plates 12 .

[0031] Among them, a first motor 15 is installed at the top of the mounting plate 10, and the output end of the first motor 15 is connected to the bidirectional screw 14 through a coupling. The first motor 15 drives the bidirectional screw 14 to rotate. Under the limiting action of the second slide groove 11, a pair of L-shaped clamping plates 12 move toward each other at the same time, so that the L-shaped clamping plates 12 can clamp both sides of the cloth. After clamping, the electric telescopic rod 9 contracts a distance to tighten the cloth, so that the cloth can always be subjected to tension during the cutting process.

[0032] A second screw rod 16 is rotatably installed in the first sliding groove 5 , and the second screw rod 16 passes through the top end of the pressing plate 6 and is threadedly connected to the pressing plate 6 .

[0033] Among them, a second motor 17 is installed at the top of the gantry 4, and the output end of the second motor 17 is connected to the second screw 16 through a coupling. The second motor 17 drives the second screw 16 to rotate. Under the limiting action of the first slide groove 5, the clamping plate 6 moves downward to press the cloth on the placement plate.

[0034] Among them, the cutting component includes a third mounting seat 18, the third mounting seat 18 is installed at the top of one side of the gantry 4, and a third slide groove 19 is provided at the bottom end of the third mounting seat 18.

[0036] Among them, the dust collection component includes a dust box 25, which is installed on one side of the top of the gantry 4, a filter 26 is installed inside the dust box 25, an electric fan 27 is installed at the bottom of the dust box 25, a dust inlet duct 28 is installed at the top of one side of the dust box 25, and the dust inlet duct 28 is connected to the air inlet 22, and an air outlet 29 is provided on one side of the dust box 25 at a position close to the output end of the electric fan 27. During the cutting process of the cutting knife 21, the electric fan 27 is turned on at the same time to discharge the air in the dust box 25 from the air outlet 29, so that negative pressure is instantly generated in the dust box 25. At this time, the fluff flying out from the cutting position enters the dust box 25 from the air inlet 22 through the dust inlet duct 28 and is adsorbed on the filter 26.

[0037] A placing plate 30 is installed at the top of the workbench 1 just below the pressing plate 6, and a collecting groove 31 is provided on one side of the top of the workbench 1 to facilitate the collection of the cut cloth.

[0038] The working principle of this embodiment is as follows: when using the cloth pulling and cutting machine to cut the cloth, the staff first places the cloth to be cut on the unwinding roller 2, pulls the cloth through the bottom end of the guide roller 3 and moves it to one side of the placement plate, and then the staff turns on the mobile cloth pulling mechanism 13 to pull the cloth, and then turns on the first motor 15 and the second motor 17 at the same time. Under the limiting action of the second slide 11, a pair of L-shaped clamping plates 12 move toward each other at the same time, so that the L-shaped clamping plates 12 can clamp both sides of the cloth. After clamping, the electric telescopic rod 9 contracts a certain distance to tighten the cloth so that the cloth can always be subjected to tension during the cutting process. The second motor 17 drives the second screw 16 to rotate. Under the limiting action of the first slide 5, the pressing plate 6 moves downward to press the cloth on the placement plate, and then turns on the third motor 2 4. The third motor 24 drives the third screw 23 to rotate. Under the limiting action of the third slide groove 19, the slider 20 moves, drives the cutting knife 21 to move and cut the cloth. If the cut cloth is cotton or wool, which is easy to produce lint, the staff can turn on the electric fan 27. The electric fan 27 discharges the air in the dust box 25 from the air outlet 29, so that negative pressure is instantly generated in the dust box 25. At this time, the lint flying out from the cutting position enters the dust box 25 from the air inlet 22 through the dust inlet duct 28 and is adsorbed on the filter screen 26, reducing the lint entering the machine and causing damage to the machine. After the cutting is completed, the L-shaped clamping plate 12 is released, and the cloth pulling mechanism 13 moves and pulls the cut cloth into the collecting tank 31, and then moves toward the direction of the gantry 4 again, waiting for the next cutting operation.
