The top surface of the second servo slide 13 is flush with the top surface of the workbench 11. The sewing machine 14 and the sewing table 15 are fixedly mounted on the top surface of the slide of the second servo slide 13 by bolts.

[0033] The first servo slide 12 can drive the second servo slide 13 to move horizontally, and the second servo slide 13 can drive the sewing machine 14 and the sewing table 15 to move longitudinally. The first servo slide 12 and the second servo slide 13 can cooperate to drive the sewing machine 14 and the sewing table 15 to move arbitrarily in the horizontal direction.

[0034] The pressing assembly 2 includes a pressing device and a flattening device. The pressing device is used to press the cloth, and the flattening device is used to flatten the cloth before sewing. The pressing device includes a pressing plate 22, which is in a square frame shape. The pressing plate 22 is located between the sewing table 15 and the head of the sewing machine 14. The head of the sewing machine 14 passes through the space enclosed by the pressing plate 22.

[0035] The pressing plate 22 is a metal plate, and the two layers of cloth pass through the upper and lower parts of the pressing plate 22 respectively.

[0036] The pressing device includes a bottom frame 21 and a top frame 23. A third servo slide 24 is connected to the side of the top frame 23 away from the sewing machine 14. The bottom frame 21 and the top frame 23 are connected to the pressing plate 22 via an adjusting assembly 25. The adjusting assembly 25 is used to ensure that the distance between the pressing plate 22 and the bottom frame 21 and the top frame 23 is the same.

[0037] The bottom frame 21 and the top frame 23 are metal frames, and the inner dimensions of the bottom frame 21 and the top frame 23 are the same as the inner dimensions of the pressure plate 22. The third servo slide 24 is vertically mounted on the top surface of the workbench 11 by bolts, and the top frame 23 is horizontally mounted on the slide of the third servo slide 24 by bolts. The third servo slide 24 can drive the top frame 23 to move vertically.

[0038] The adjustment assembly 25 includes an adjustment plate 251, which is welded and installed on the front and rear sides of the bottom frame 21 and the top frame 23. A guide column 252 is welded on the top surface of the adjustment plate 251 of the bottom frame 21. The guide column 252 penetrates upward through the adjustment plate 251 at the pressure plate 22 and the top frame 23. The adjustment plates 251 at the pressure plate 22 and the top frame 23 can slide up and down along the guide column 252. Two adjustment springs 253 are sleeved on each guide column 252 and located between the adjustment plates 251. The two adjustment springs 253 are located on the upper and lower sides of the pressure plate 22, and the two ends of the adjustment spring 253 are respectively against the pressure plate 22 and the adjustment plate 251.

[0039] When the third servo slide 24 drives the top frame 23 to move upward, the adjustment plate 251 at the top frame 23 moves upward, and the adjustment spring 253 between the pressure plate 22 and the adjustment plate 251 at the top frame 23 is released. The elastic force of the adjustment springs 253 on the upper and lower sides of the pressure plate 22 produces a difference, and the lower adjustment spring 253 also begins to stretch, driving the pressure plate 22 to move upward until the elastic force of the adjustment springs 253 on the upper and lower sides of the pressure plate 22 is balanced.

[0040] The flattening device includes 8 tensioning rollers 26, which are rotatably mounted on the edges of the base frame 21 and the top frame 23, and the tensioning rollers 26 on the base frame 21 and the top frame 23 are abutted against each other. The axis of the tensioning roller 26 forms an angle of 45° with the long axis of the base frame 21 and the top frame 23, and a tensioning motor 27 is connected to the end of the tensioning roller 26.

[0041] The tensioning motor 27 adopts a servo motor, and the output shaft of the tensioning motor 27 is fixedly connected to the end of the tensioning roller 26 through a coupling, and the tensioning motor 27 can drive the tensioning roller 26 to rotate. When the tensioning roller 26 rotates, since the tensioning roller 26 and the long axis of the bottom frame 21 and the top frame 23 form a 45° angle, the cloth will be driven to move away from the center of the bottom frame 21 and the top frame 23 in a 45° direction. The eight tensioning rollers 26 cooperate with each other to achieve torque balance, which can realize the tensioning of the cloth.

[0042] The flattening device further includes a feed roller 28 , which is mounted on the short edge of the bottom frame 21 and the top frame 23 facing the pressing plate 22 , the feed roller 28 abuts against the pressing plate 22 , and is connected to a feed motor 29 .

[0043] There are four feed rollers 28, which are rotatably mounted on the short edge of the bottom frame 21 and the top frame 23 facing the pressure plate 22. The feed motor 29 adopts a servo motor, and the feed motor 29 is fixedly mounted on the bottom frame 21 and the top frame 23 facing the third servo slide 24 by bolts. The output shaft of the feed motor 29 is fixedly connected to the feed roller 28 through a coupling, and the feed motor 29 can drive the feed roller 28 to rotate. When the feed roller 28 presses the cloth and rotates in the same direction, it can drive the cloth forward to realize automatic feeding. When the feed rollers 28 on both sides of the bottom frame 21 and the top frame 23 are opposite, the cloth can be pulled to both sides to realize the flattening of the cloth.

[0044] The cutting assembly 3 is located on the side of the pressing assembly 2. The cutting assembly 3 includes a measuring device and a cutting device.

[0045] The measuring motor 32 adopts a servo motor. The measuring motor 32 is fixedly installed on the side of the first frame 34 by bolts. There are two measuring motors 32. The output shafts of the two measuring motors 32 are fixedly connected to the measuring roller 31 and the guide roller 33 through a coupling. The measuring motor 32 can measure the rotation of the measuring roller 31 and the guide roller 33 in the same direction, thereby driving the stitched fabric forward. By controlling the number of revolutions of the measuring motor 32, the number of revolutions of the measuring roller 31 and the guide roller 33 can be controlled, thereby controlling the forward length of the stitched fabric. Length measurement is achieved. After the fabric exceeds the guide roller 33, it will sag under the influence of its own weight.

[0046] The cutting device comprises a second frame 35 , which is fixedly mounted on the side of the first frame 34 by bolts, and a laser cutting head 38 is mounted on the side of the second frame 35 facing the first frame 34 through a screw drive device.

The output shaft of the cutting motor 36 passes through the second frame 35 and is fixedly connected to a cutting screw 37, which is threadedly connected to a laser cutting head 38.

[0049] When the cutting motor 36 rotates, it can drive the cutting screw 37 to rotate. Since the cutting screw 37 is threadedly connected to the laser cutting head 38, when the cutting screw 37 rotates, it can drive the laser cutting head 38 to move along the axis direction of the cutting screw 37. The movement of the laser cutting head 38 is used to achieve horizontal cutting of the cloth.

[0050] When using the device, first use the third servo slide 24 to drive the top frame 23 to rise, and the adjustment plate 251 at the top frame 23 moves upward. The adjustment spring 253 between the pressure plate 22 and the adjustment plate 251 at the top frame 23 is released, and the elastic force of the adjustment springs 253 on the upper and lower sides of the pressure plate 22 produces a difference. The lower adjustment spring 253 also begins to stretch, driving the pressure plate 22 to move upward until the elastic force of the adjustment springs 253 on the upper and lower sides of the pressure plate 22 is balanced.

[0051] At this time, the pressing plate 22 and the upper frame 23 and the bottom frame 21 are separated, and the two layers of cloth are passed through the upper and lower sides of the pressing plate 22 respectively, and then the upper frame 23 is driven down by the third servo slide 24, and the adjustment plate 251 at the upper frame 23 is lowered, pressing down the adjustment spring 253, driving the pressing plate 22 to descend, until the feeding rollers 28 on the upper and lower sides press the cloth.

[0052] The tensioning motor 27 is started, and the tensioning motor 27 drives the tensioning roller 26 to rotate, driving the cloth to move in a direction obliquely at 45 degrees, thereby achieving the tensioning of the cloth.

[0053] The sewing machine 14 is started, and the first servo slide 12 and the second servo slide 13 are used to drive the sewing machine 14 and the sewing table 15 to move on a horizontal plane to complete sewing of the cloth.

[0054] After sewing is completed, the feeding motor 29 is started to drive the fabric to move toward the cutting assembly 3, and the subsequent fabric is delivered to the middle of the pressing plate 22. The measuring motor 32 is used to drive the measuring roller 31 and the guide roller 33 to rotate. The number of rotations of the measuring motor 32 is controlled to control the number of rotations of the measuring roller 31 and the guide roller 33 to achieve fabric measurement. When the stitching pattern is located below the laser cutting head 38, the feeding motor 29 and the measuring motor 32 are stopped.

[0055] After being tensioned by the tensioning roller 26, the first servo slide 12 and the second servo slide 13 drive the sewing machine 14 and the sewing table 15 to move on the horizontal plane to perform the second sewing.

[0056] At the same time, the cutting motor 36 and the laser cutting head 38 are started, and the cutting motor 36 drives the cutting screw 37 to rotate, driving the laser cutting head 38 to move. When the laser cutting head 38 moves horizontally, it cuts the stitched cloth, completing the cloth cutting.
