[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0046] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0048] The purpose of this invention is to provide a trouser placket machine that can ensure the consistency of the stop distance and improve sewing quality.

[0049] Please see Figures 1 to 5 To achieve the above objectives, this utility model provides a trouser placket machine, including a fabric flap 100. The fabric flap 100 includes a left flap 110, a right flap 120, and a middle seam 130 located between the left flap 110 and the right flap 120. The width of the middle seam 130 in the horizontal direction is greater than the thickness of the left front piece 200 and less than the thickness at the seam position 310 of the left front piece 200 and the connecting piece 300. The middle seam 130 is used for the left front piece 200 to pass through, and the seam position 310 located below the right flap 120 abuts against the entrance of the middle seam 130.

[0050] After the left front piece 200 and the connecting piece 300 are sewn together by a sewing machine, the sewing position 310 of the left front piece 200 and the connecting piece 300 has three layers of fabric. The thickness of the sewing position 310 is relatively large. When the left front piece 200 passes through the middle seam 130 from bottom to top and is pulled to the left, the part of the left front piece 200 located below the fabric turning baffle 100 and the connecting piece 300 sewn to the left front piece 200 move to the left until one end of the sewing position 310 moves to the entrance of the middle seam 130. At this time, because the thickness of the sewing position 310 is greater than the width of the middle seam 130 in the horizontal direction, the sewing position 310 cannot enter the middle seam 130 and is positioned. This setting can ensure the consistency of the stop distance and improve the sewing quality.

[0051] In one possible implementation, the system further includes a worktable 400, a movable plate 500, a first slider 600, and a first adjusting plate 800. The movable plate 500 is located above the worktable 400 and has a slide rail 510. The first slider 600 is connected to the slide rail 510 and can move along the extension direction of the slide rail 510. The first slider 600 is connected to a first fixed seat 700. The first adjusting plate 800 can move relative to the first fixed seat 700 in the height direction and is fixedly connected to the fabric turning baffle 100. The first adjusting plate 800 can move relative to the first fixed seat 700 in the height direction to adjust the distance between the fabric turning baffle 100 and the worktable 400 in the height direction. Then, the first adjusting plate 800 and the first fixed seat 700 are fixed by a first fixing member 900 to stabilize the position of the fabric turning baffle 100.

[0052] In one possible implementation, the seam position 310 between the left front panel 200 and the two side panels 300 includes one layer of left front panel 200 and two layers of side panels 300. The width of the middle seam 130 in the horizontal direction is greater than the thickness of one layer of left front panel 200 and less than the sum of the thicknesses of one layer of left front panel 200 and the two side panels 300. Specifically, when the thicknesses of the left front panel 200 and the side panels 300 are the same, the width of the middle seam 130 in the horizontal direction is greater than the thickness of one layer of left front panel 200 and less than the sum of the thicknesses of the two side panels 300. To ensure the blocking effect of the middle seam 130 on the stitching position 310 of the left front piece 200 and the connecting piece 300, given the thickness of the three-layer left front piece 200, it is preferable that the width of the middle seam 130 in the horizontal direction is greater than the thickness of the left front piece 200 and less than the sum of the thicknesses of the left front piece 200 and the connecting piece 300. Furthermore, when the thicknesses of the front piece and the connecting piece 300 are the same, the width of the middle seam 130 in the horizontal direction is greater than the thickness of the first layer of left front piece 200 and less than the thickness of the second layer of left front piece 200.

[0053] In one possible implementation, the thickness of the right flap 120 in the height direction is 1mm-6mm. The left front piece 200 and the connecting piece 300 of the trouser fabric are sewn together with a sewing machine. The left front piece 200 of the trouser fabric is inserted into the middle seam 130 of the folding flap 100 and then pulled to the left. When it is pulled to the seam position 310, the thickness increases and it cannot pass through the middle seam 130, so it cannot be pulled to the left any further. At this point, the stop position is secured. When the left front piece 200 of the trouser fabric is folded to the right, due to the action of the right flap 120, the left front piece 200 of the trouser fabric will cover the connecting piece 300. At this time, the length of the left front piece 200 located inside the middle seam 130 is consistent with the thickness of the right flap 120 in the height direction. After the subsequent fabric is removed from the folding flap 100, the left front piece 200 protrudes 0.5mm-3mm from the seam position 310. The size of the protrusion is controlled by the thickness of the right flap 120.

[0054] In one possible implementation, the first adjusting plate 800 has a first guide groove 810 at one end facing the first fixed base 700, and the first guide groove 810 extends along the height direction. The first fixed base 700 has a first limiting part 710 at one end facing the first adjusting plate 800. The first guide groove 810 has a first contact surface located on both sides of the first guide groove 810 in the left-right direction. The first limiting part 710 has a second contact surface located on both sides of the first limiting part 710 in the left-right direction. The second contact surface is used to contact with the first contact surface, so that the first limiting part 710 and the first guide groove 810 can move relative to each other in the height direction. This is to avoid horizontal offset during the relative movement of the first adjusting plate 800 and the first fixed base 700 in the height direction, and to facilitate subsequent fixation of the first adjusting plate 800 and the first fixed base 700 by the first fixing member 900.

[0055] In one possible implementation, the first limiting part 710 has a first connecting hole 711 at one end located within the first guide groove 810, and the first adjusting plate 800 has a first strip hole 820. The length direction of the first strip hole 820 is parallel to the height direction, and the first strip hole 820 communicates with the first guide groove 810. The first fixing member 900 passes through the first strip hole 820 and connects to the first connecting hole 711, so that the first adjusting plate 800 and the first fixing seat 700 are fixedly connected. The first connecting hole 711 may be, but is not limited to, a horizontally extending threaded hole, and the number of first connecting holes 711 may be, but is not limited to, two. The first fixing member 900 may be, but is not limited to, a screw. The threaded section of the first fixing member 900 passes through the first strip hole 820 and connects to the first connecting hole 711. Simultaneously, the stop of the first fixing member 900 abuts against the first adjusting plate 800 to restrict the movement of the first adjusting plate 800.

[0056] In one possible implementation, the first fixing base 700 further includes a first fixing part 720 connected to the first limiting part 710. The first fixing part 720 is located above the first slider 600, and the first fixing part 720 and the first slider 600 are fixedly connected by a first connecting member 1000. Specifically, the first slider 600 is provided with a first mounting hole, and the first fixing part 720 is provided with a second mounting hole. The first mounting hole and the second mounting hole correspond one-to-one. The first connecting member 1000 passes through the second mounting hole and is connected to the first mounting hole. The first mounting hole and the second mounting hole can be, but are not limited to, threaded holes, and the first connecting member 1000 can be, but is not limited to, a screw or threaded rod. The first fixing base 700 can be adjusted to move closer to or further away from the first slider 600 in the height direction through the first connecting member 1000, thereby achieving height adjustment of the fabric flipping baffle 100.

[0057] In one possible implementation, a second slider 1100 and a stop forming plate 1300 are also included. The second slider 1100 is connected to the slide rail 510 and is movable along the extension direction of the slide rail 510. The second slider 1100 is connected to a second fixing seat 1200. The stop forming plate 1300 is located below the left stop portion 110. When the left front piece 200 passes through the middle seam 130, the right end of the stop forming plate 1300 is positioned below the middle seam 130, so that the right end of the stop forming plate 1300 abuts against the left end of the stitching position 310 of the left front piece 200 and the connecting piece 300. The stop forming plate 1300 is connected to a second adjusting plate 1400 that is movable in the height direction relative to the second fixing seat 1200. A second fixing member 1500 is used to connect the second adjusting plate 1400 and the second fixing seat 1200, so that the second adjusting plate 1400 and the second fixing seat 1200 are relatively fixed. The second adjusting plate 1400 can move in the height direction relative to the second fixed seat 1200 to adjust the distance in the height direction between the stop forming plate 1300 and the worktable 400. Then, the second adjusting plate 1400 and the second fixed seat 1200 are fixed by the second fixing member 1500 to make the position of the stop forming plate 1300 stable. By adjusting the height of the stop forming plate 1300, the width of the gap in the height direction between the stop forming plate 1300 and the fabric turning baffle 100 can be adjusted.

[0058] In one possible implementation, the second adjusting plate 1400 has a second guide groove 1410 at one end facing the second fixed base 1200, and the second guide groove 1410 extends along the height direction. The second fixed base 1200 has a second limiting part 1210 at one end facing the second adjusting plate 1400. The second guide groove 1410 has a third contact surface located on both sides of the second guide groove 1410 in the left-right direction. The second limiting part 1210 has a fourth contact surface located on both sides of the second limiting part 1210 in the left-right direction. The fourth contact surface is used to contact with the third contact surface, so that the second limiting part 1210 and the second guide groove 1410 can move relative to each other in the height direction. This is to avoid horizontal offset during the relative movement of the second adjusting plate 1400 and the second fixed base 1200 in the height direction, and to facilitate subsequent fixation of the second adjusting plate 1400 and the second fixed base 1200 by the second fixing member 1500.

[0059] In one possible implementation, the second limiting part 1210 has a second connecting hole 1211 at one end located within the second guide groove 1410, and the second adjusting plate 1400 has a second strip-shaped hole 1420. The length direction of the second strip-shaped hole 1420 is parallel to the height direction, and the second strip-shaped hole 1420 communicates with the second guide groove 1410. The second fixing member 1500 passes through the second strip-shaped hole 1420 and is connected to the second connecting hole 1211, so that the second adjusting plate 1400 and the second fixing seat 1200 are fixedly connected. The second connecting hole 1211 may be, but is not limited to, a horizontally extending threaded hole, and the number of second connecting holes 1211 may be, but is not limited to, two. The second fixing member 1500 may be, but is not limited to, a screw. The threaded section of the second fixing member 1500 passes through the second strip-shaped hole 1420 and is connected to the second connecting hole 1211. At the same time, the stop of the second fixing member 1500 abuts against the second adjusting plate 1400 to restrict the movement of the second adjusting plate 1400.

[0060] In one possible implementation, the second fixing seat 1200 includes a second fixing part 1220 connected to the second limiting part 1210. The second fixing part 1220 is located above the second slider 1100, and the second fixing part 1220 and the second slider 1100 are fixedly connected by a second connector 1600. Specifically, the second slider 1100 is provided with a third mounting hole, and the second fixing part 1220 is provided with a fourth mounting hole. The third mounting hole and the fourth mounting hole correspond one-to-one. The second connector 1600 passes through the fourth mounting hole and is connected to the third mounting hole. The third mounting hole and the fourth mounting hole can be, but are not limited to, threaded holes, and the second connector 1600 can be, but is not limited to, a screw or threaded rod. The second fixing seat 1200 can be adjusted to move closer to or further away from the second slider 1100 in the height direction through the second connector 1600, which can also achieve height adjustment of the stop forming plate 1300.
