The meshing sides of the first support plate rack 18 and the first pressure plate rack 20 are arranged upward, and the meshing sides of the second support plate rack 19 and the second pressure plate rack 21 are arranged downward;

[0027] The first supporting movable plate 3 and the second supporting movable plate 4 are respectively connected to the first supporting plate 22 and the second supporting plate 23, and the first pressing movable plate 5 and the second pressing movable plate 6 are respectively connected to the first pressing plate 24 and the second pressing plate 25. Specifically, the two supporting bases 1 are respectively connected to the two ends of the first supporting plate 22 via the first supporting movable plate 3 in the adjustment assembly installed above them, the two supporting bases 1 are respectively connected to the two ends of the second supporting plate 23 via the second supporting movable plate 4 in the adjustment assembly installed above them, the two supporting bases 1 are respectively connected to the two ends of the first pressing plate 24 via the first pressing movable plate 5 in the adjustment assembly installed above them, and the two supporting bases 1 are respectively connected to the two ends of the second pressing plate 25 via the second pressing movable plate 6 in the adjustment assembly installed above them.

[0028] Working principle:

[0029] When the fabric to be sewn is pressed, the fabric to be sewn is laid on the upper surface of the first support plate 22 and the second support plate 23, and then the first pressing plate 24 and the second pressing plate 25 are controlled to press and fix downward. When the width of the fabric to be sewn changes (the width direction of the fabric to be sewn is parallel to the support base 1 and perpendicular to the length direction of the first support plate 22), the servo motors 7 on the two support bases 1 can be controlled to operate synchronously, and then the driving end of the servo motor 7 drives the active pulley 8 to rotate, and then the synchronous transmission effect of the synchronous belt 13 can drive the first driven pulley 11 and the second driven pulley 12 to rotate synchronously, and then drive the first rotating shaft 9 and the second rotating shaft 10 to rotate synchronously, so that the first rotating shaft 9 can drive the first support plate gear 14 and the first pressing plate gear 15 at both ends thereof to rotate synchronously, and the second rotating shaft 10 can drive the second support plate gear 16 and the second pressing plate gear 17 at both ends thereof to rotate synchronously.

[0030] Afterwards, the first support plate gear 14 is meshed with the first support plate rack 18, and the second support plate gear 16 is meshed with the second support plate rack 19. Since the meshing sides of the first support plate rack 18 and the second support plate rack 19 are arranged relative to each other, the first support plate gear 14 and the second support plate gear 16 can be used to synchronously rotate forward or reverse to drive the first support plate rack 18 and the second support plate rack 19 to move in the direction of approaching or moving away from each other, thereby driving the first support movable plate 3 and the second support movable plate 4 to move in the direction of approaching or moving away from each other; and then the width between the first support plate 22 and the second support plate 23 is opened and closed, that is, the distance between the first support plate 22 and the second support plate 23 is adjusted to meet the requirements of fabrics to be sewn of different widths.

[0031] At the same time, the first pressure plate gear 15 is meshed with the first pressure plate rack 20, and the second pressure plate gear 17 is meshed with the second pressure plate rack 21. Since the meshing sides of the first pressure plate rack 20 and the second pressure plate rack 21 are arranged relatively to each other, the first pressure plate gear 15 and the second pressure plate gear 17 can be used to rotate forward or reverse synchronously to drive the first pressure plate rack 20 and the second pressure plate rack 21 to move toward each other or away from each other, and then drive the first pressure movable plate 5 and the second pressure movable plate 6 to move toward each other or away from each other; then the width between the first pressure plate 24 and the second pressure plate 25 can be opened and closed to adapt to the requirements of fabrics to be sewn of different widths.

[0032] And since the first support plate gear 14, the first pressure plate gear 15, the second support plate gear 16 and the second pressure plate gear 17 all rotate synchronously, and the first support plate gear 14, the first pressure plate gear 15, the second support plate gear 16 and the second pressure plate gear 17 are of the same model, it can effectively ensure that the width opening and closing adjustment direction and size between the first support plate 22 and the second support plate 23 are synchronized with the width opening and closing adjustment direction and size between the first pressure plate 24 and the second pressure plate 25, thereby effectively ensuring that the first pressure plate 24 and the second pressure plate 25 can always be directly opposite the first support plate 22 and the second support plate 23.

[0033] The entire process is achieved by controlling the synchronous operation of the servo motors 7 on the two support bases 1, thereby achieving the synchronous opening and closing effect of the first clamping plate 24 and the second clamping plate 25, and the first support plate 22 and the second support plate 23, thereby greatly improving the switching efficiency for products of different widths and greatly reducing the changeover cost.

[0034] In this embodiment, the servo motor 7 can be connected to the controller, and the controller can be used to control the rotation direction and number of revolutions of the servo motor 7, thereby achieving precise control of the opening and closing dimensions of the first support plate 22 and the second support plate 23, the first clamping plate 24 and the second clamping plate 25 to adapt to the dimensions of products of different widths and effectively ensure positioning accuracy.

[0035] Example 2, as a further preferred embodiment of Example 1, a first slider and a second slider are fixedly installed on one side of the support frame 2, and a third slider and a fourth slider are fixedly installed on the other side of the support frame 2. The inner side surface of the first supporting movable plate 3, the inner side surface of the second supporting movable plate 4, the inner side surface of the first clamping movable plate 5 and the inner side surface of the second clamping movable plate 6 are all horizontally fixedly installed with the first slide rail 26, the second slide rail 27, the third slide rail 28 and the fourth slide rail 29 respectively. The first slider, the second slider, the third slider and the fourth slider are slidably connected to the first slide rail 26, the second slide rail 27, the third slide rail 28 and the fourth slide rail 29 respectively.

[0036] By providing the first slide rail 26, the second slide rail 27, the third slide rail 28, and the fourth slide rail 29, when the first supporting movable plate 3, the second supporting movable plate 4, the first pressing movable plate 5, and the second pressing movable plate 6 are moving, the first slide rail 26, the second slide rail 27, the third slide rail 28, and the fourth slide rail 29 can guide the first supporting movable plate 3 along the axial direction of the first slide rail 26, the second supporting movable plate 4 along the axial direction of the second slide rail 27, the first pressing movable plate 5 along the axial direction of the third slide rail 28, and the second pressing movable plate 6 along the axial direction of the fourth slide rail 29. This effectively ensures the stability of the first supporting movable plate 3, the second supporting movable plate 4, the first pressing movable plate 5, and the second pressing movable plate 6 during movement.

[0037] Example three, as a further preferred solution of Example one, the first lifting slide module 30 is fixedly installed on the outer side surface of the first clamping movable plate 5, and the second lifting slide module 31 is fixedly installed on the outer side surface of the second clamping movable plate 6. The first lifting slide module 30 is slidingly connected to the side of the first lifting slide module 30, and the second lifting slide module 31 is slidingly connected to the side of the second lifting slide module 31. The first moving blocks 32 are respectively fixedly installed at both ends of the first clamping plate 24, and the second moving blocks 33 are respectively fixedly installed at both ends of the second clamping plate 25.

[0038] In the initial state, the first movable block 32 is located above the first lifting slide module 30, and the second movable block 33 is located above the second lifting slide module 31. During use, the servo motor 7 is first operated to drive the first and second pressing plates 24, 25, and the first and second support plates 22, 23 to open and close to the appropriate widths; then, the fabric to be sewn is laid on the upper surfaces of the first and second support plates 22, 23. The first and second lifting slide modules 30, 31 are then controlled to operate synchronously, driving the first and second movable blocks 32, 33 to move downward synchronously, and further driving the first and second pressing plates 24, 25 to move downward synchronously, respectively, to press against the upper surfaces of the first and second support plates 22, 23, thereby achieving a compacting and fixing effect on the fabric to be sewn.

[0039] After sewing is completed, the first lifting slide module 30 and the second lifting slide module 31 are controlled to rotate synchronously in the opposite direction to drive the first moving block 32 and the second moving block 33 to move upward to the initial position synchronously, and then the sewn fabric can be taken out manually.

[0040] In this embodiment, the first and second lift modules 30 and 31 utilize conventionally known technical solutions, which are readily understood by those skilled in the art and will not be further described. Furthermore, the control ports of the first and second lift modules 30 and 31 can be connected to a controller to achieve synchronous control of the first and second lift modules 30 and 31.

[0041] In the fourth embodiment, a plurality of press cylinders 38 are mounted on the upper surfaces of the first and second press plates 24, 25. The telescopic shafts of the press cylinders 38 pass through the first and second press plates 24, 25, respectively, and are fixedly connected to a press plate 39. Therefore, after the first and second lift slide modules 30, 31 drive the first and second press plates 24, 25 downwardly to press against the upper surface of the fabric to be sewn, the telescopic shafts of the press cylinders 38 can be controlled to extend, thereby driving the press plate 39 downwardly to press against the upper edge of the fabric to be sewn, thereby further ensuring the stability of the fabric to be sewn during the sewing process.

[0042] In Example 5, a further preferred embodiment of Example 1, fixed blocks 34 are mounted on both sides of the upper surface of the support frame 2. An adjusting screw 35 is threadedly connected to the center of the fixed block 34. The screw end of the adjusting screw 35 passes through the fixed block 34 and is fixedly mounted to a pressure roller seat 36. A tensioning pulley 37 is rotatably mounted within the pressure roller seat 36 via a rotating shaft. The outer ring of the tensioning pulley 37 is pressed against the outer surface of the timing belt 13. Therefore, by rotating the adjusting screw 35, the pressure roller seat 36 can be driven to move toward the timing belt 13, thereby tightening the timing belt 13 via the tensioning pulley 37. This effectively ensures the tension of the timing belt 13.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
