Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Reference Figures 1-3 The device for fixing and cutting polyurethane impregnated simulated leather fabric includes a first table 1. The device is characterized by: a cutting table 2 fixedly connected to the back of the first table 1; a second table 3 fixedly connected to the back of the cutting table 2; table legs 4 fixedly connected to the bottom of the first table 1 and the second table 3; an edge-pressing module 5 on the top of the cutting table 2; a vertical plate 6 fixedly connected to the top of the second table 3; a horizontal plate 7 fixedly connected to the top of the vertical plate 6; an auxiliary plate 8 fixedly connected to the front of the horizontal plate 7; a circular hole on the top of the auxiliary plate 8; a cylinder 9 on the top of the auxiliary plate 8; the cylinder 9 being threadedly connected to the auxiliary plate 8 via a cylinder bolt; and a cylinder rod 10 at the bottom of the cylinder 9, which is compatible with the circular hole.

[0019] The cylinder rod 10 is threadedly connected to a clamping plate 11. A threaded hole is provided on the front of the clamping plate 11, and a clamping plate bolt is threadedly connected inside the threaded hole. An auxiliary block 12 is threadedly connected to the clamping plate 11 through the clamping plate bolt. A tool connecting block 13 is fixedly connected to the bottom of the auxiliary block 12.

[0021] The fabric is placed on top of the cutting table 2. At this time, the fabric is fixed by the edge pressing module 5 and airflow is blown out to form an airflow film on the fabric, thereby reducing the electrostatic adsorption phenomenon generated by the cutter 14 during cutting. After the fabric is fixed, the cylinder 9 is started and the cylinder rod 10 moves downward, which in turn drives the cutter 14 and the anti-cutting fuzzing module 15 to move downward together. The cutter 14 cuts the fabric, while the anti-cutting fuzzing module 15 blows low-temperature hot air to the cut part of the fabric, so that the cut section is heat-melted and then pressed firmly to prevent fuzz or fray from appearing at the cut part.

[0022] As a preferred embodiment of this example, Figures 4 to 6 As shown, the pressing module 5 includes a placement ring 501, a first table plate 1 is fixedly connected to the top of the placement ring 501, a compressed gas cylinder 502 is installed on the inner wall of the placement ring 501, a head straight pipe 503 is fixedly connected to one end of the compressed gas cylinder 502, and a threaded joint 504 is fixedly connected to the surface of the head straight pipe 503.

[0023] One end of the threaded connector 504 is threadedly connected to an electric control valve 505. The surface of the electric control valve 505 is threadedly connected to an air supply pipe 506. The electric control valve 505 is installed with a first cavity box 507 through the air supply pipe 506. A second cavity box 508 is fixedly connected to the side of the first cavity box 507.

[0024] The bottom of the second cavity box 508 is provided with an airbag 509. The bottom of the first cavity box 507 is fixedly connected with a short upright plate 510. The side of the second cavity box 508 is provided with a first air nozzle connection end 511. The first air nozzle connection end 511 is internally threaded with a first air nozzle 512. One end of the first air nozzle 512 is fixedly connected with a transverse cylinder 513. One end of the transverse cylinder 513 is provided with an isolation plate 514. The isolation plate 514 is threadedly connected to the transverse cylinder 513 through an isolation plate bolt.

[0025] Placement ring 501 is welded to the bottom of the first table 1. Compressed gas cylinder 502 is installed inside placement ring 501. End cap straight pipe 503 is integrally connected to compressed gas cylinder 502, and threaded joint 504 is integrally connected to end cap straight pipe 503. Electric control valve 505 is installed between threaded joint 504 and gas supply pipe 506. Gas supply pipe 506 is installed between electric control valve 505 and first cavity box 507. First cavity box 507 and second cavity box 508 are welded together. Airbag 509 is integrally connected to second cavity box 508. Short upright plate 510 is welded between first cavity box 507 and cutting table 2. First air nozzle connection end 511 is welded to second cavity box 508. First air nozzle 512 is screwed into first air nozzle connection end 511. Transverse cylinder 513 is welded to first air nozzle 512. Isolation plate 514 is installed to transverse cylinder 513 by isolation plate bolts.

[0026] The electric control valve 505 is activated, allowing gas from the compressed gas cylinder 502 to pass through the valve and enter the gas supply pipe 506. The gas then enters the first cavity box 507 via the gas supply pipe 506. After a brief pause, the gas enters the second cavity box 508. The gas in the second cavity box 508 then enters the connection between the airbag 509 and the first air nozzle 511, inflating the airbag 509 and securing the fabric. Meanwhile, the gas in the first air nozzle connection 511 enters the first air nozzle 512 and is sprayed onto the fabric surface, forming an air film. This reduces the possibility of electrostatic adsorption during cutting. The isolation plate 514 prevents foreign objects from entering the first air nozzle 512.

[0027] By setting the edge pressing module 5, the device can press and fix the edges of conventional fabrics. This reduces the possibility of indentations caused by traditional rigid pressing plates. At the same time as pressing the edges, airflow is sprayed onto the fabric to reduce the possibility of electrostatic adsorption during cutting. One module has two functions, which increases the device's competitiveness in the market to a certain extent.

[0028] like Figures 7 to 9 As shown, in this embodiment, the anti-cutting and fraying module 15 includes a track plate 1501. A tool connecting block 13 is fixedly connected to one side of the track plate 1501. A connecting threaded hole is opened on the side of the track plate 1501. A connecting bolt is threaded inside the connecting threaded hole. A slider 1502 is threadedly connected to the track plate 1501 through the connecting bolt.

[0029] The front of the slider 1502 is fixedly connected to the third cavity box 1503. The bottom of the third cavity box 1503 is fixedly connected to the second air nozzle connection end 1504. The second air nozzle connection end 1504 is internally threaded with the second air nozzle 1505. The top of the third cavity box 1503 is fixedly connected to the threaded connector 1506. The front of the third cavity box 1503 is fixedly connected to the rectangular rigid plate 1507.

[0030] A silicone plate 1508 is provided at the bottom of the rectangular rigid plate 1507, a guide plate 1509 is provided on the back of the silicone plate 1508, and a blower 1510 is provided at the top of the rectangular rigid plate 1507. The blower 1510 is connected to the rectangular rigid plate 1507 by a blower bolt thread. A connecting pipe 1511 is threadedly connected to the surface of the threaded connector 1506, and the blower 1510 is installed on the threaded connector 1506 through the connecting pipe 1511.

[0031] The track plate 1501 is welded to the side of the tool connecting block 13. The slider 1502 is slid into the track plate 1501 and then fixed together with connecting bolts. The third cavity box 1503 is welded to the front of the slider 1502. The second air nozzle connecting end 1504 is welded to the bottom of the third cavity box 1503. The second air nozzle 1505 is screwed to the bottom of the second air nozzle connecting end 1504. The threaded connector 1506 is integrally connected to the third cavity box 1503. The rectangular hard plate 1507 is welded to the front of the third cavity box 1503. The silicone plate 1508 is integrally connected to the rectangular hard plate 1507. The guide plate 1509 is integrally connected to the silicone plate 1508. The blower 1510 is installed on the top of the rectangular hard plate 1507 with blower bolts. The connecting pipe 1511 is installed between the threaded connector 1506 and the blower 1510.

[0032] First, adjust the height of slider 1502 inside track plate 1501 according to the thickness of the fabric. Then, start blower 1510. Low-temperature hot air blown out by blower 1510 enters the third cavity box 1503 through connecting pipe 1511. After the gas stays briefly in the third cavity box 1503, it enters the second air nozzle 1505 from the second air nozzle connection end 1504 and is sprayed out from the second air nozzle 1505. The blown low-temperature hot air will be affected by the guide plate 1509, so that the low-temperature hot air can cover a larger area. The low-temperature hot air can heat melt the fabric at the cut section and the surrounding area, so that the fabric can be shaped. At this time, silicone plate 1508 will also press on the fabric, thereby re-sealing and compacting the shaped and fuzzy fabric, thereby reducing the probability of fuzzing at the cut section during cutting.

[0033] By setting an anti-fuzzing module 15, the module can fall together with the cutter 14. After the cutter 14 finishes cutting the fabric, the module can heat-melt and press the cut part to shape it, thereby reducing the possibility of fuzzing at the cut position during cutting to a certain extent, and thus reducing the possibility of affecting product quality due to fuzzing at the cut position of the fabric.

[0034] The working principle of this practical application is as follows: The fabric is placed on top of the cutting table 2. The edge-pressing module 5 then secures the fabric and blows air to form an airflow film on it, reducing electrostatic adsorption by the cutter 14 during cutting. After the fabric is secured, the cylinder 9 is activated, causing the cylinder rod 10 to move downwards. This, in turn, moves the cutter 14 and the anti-fuzzing module 15 downwards together. The cutter 14 cuts the fabric, while the anti-fuzzing module 15 blows low-temperature hot air onto the cut area, causing the cut surface to melt and then press it down to prevent fraying or rough edges. When the fabric is raised, the electronic control valve 505 is activated, allowing gas from the compressed gas cylinder 502 to pass through the valve and enter the gas delivery pipe 506. The gas then enters the first cavity housing 507 via the pipe 506. After a brief pause in the first cavity housing 507, the gas enters the second cavity housing 508. The gas in the second cavity housing 508 then enters the connection between the airbag 509 and the first air nozzle 511, inflating the airbag 509 and thus securing the fabric. The first air nozzle connection 511... The gas inside the first nozzle 512 enters the first nozzle 512 and is sprayed onto the surface of the fabric, forming an air film. This reduces the possibility of electrostatic adsorption during cutting. The isolation plate 514 prevents foreign objects from entering the first nozzle 512. First, adjust the height of the slider 1502 inside the track plate 1501 according to the thickness of the fabric. Then, start the blower 1510. The low-temperature hot air blown out by the blower 1510 enters the third cavity box 1503 through the connecting pipe 1511. The gas stays briefly in the third cavity box 1503. The air enters the second air nozzle 1505 from the second air nozzle connection end 1504 and is ejected from the second air nozzle 1505. The blown-out low-temperature hot air will be affected by the guide plate 1509, so that the low-temperature hot air can cover a larger area. The low-temperature hot air can heat melt the fabric at the cut section and the surrounding area, so that the fabric can be shaped. At this time, the silicone plate 1508 will also press onto the fabric, thereby re-sealing and compacting the shaped and fuzzy fabric, thereby reducing the probability of fuzzing at the cut section during cutting.

[0035] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
