[0045] like Figure 1-Figure 6 As shown, the folding module 3 includes a folding positioning seat 31, a folding upper and lower cylinders 32 installed on the frame 1 and used to drive the folding positioning seat 31 to move up and down, and a pressing assembly 33, a bag bottom folding assembly 34, two bag side folding assemblies 35 and two upper bag corner folding assemblies 36, which are respectively installed on the folding positioning seat 31 and cooperate with each other. Therefore, the above-mentioned bag bottom folding assembly 34, two bag side folding assemblies 35 and two upper bag corner folding assemblies 36 can be used to fold the bag bottom, bag side and upper bag corner of the pocket cloth.

[0046] like Figure 1-Figure 6 As shown, the material pressing assembly 33 includes a bag pressing plate 332 which can be detachably mounted on the bottom of the hem folding positioning seat 31 through a quick release screw 331, and a bag pressing groove 333 corresponding to the shape of the pocket fabric is arranged on the bottom surface of the bag pressing plate 332. Therefore, the bag pressing plate 332 can be quickly disassembled and assembled through the arrangement of the quick release screw 331, so as to replace the bag pressing groove 333 of different shapes, so that the present invention can be applied to pocket fabrics of different shapes.

[0047] like Figure 1-Figure 6 As shown, the bag bottom folding assembly 34 includes a bag bottom folding cylinder 341 which is installed on the left end of the folding positioning seat 31 so as to be adjustable left and right, and a bag bottom folding piece 342 which is connected to the output shaft of the bag bottom folding cylinder 341 so as to be adjustable up and down and is located below the bag pressing plate 332.

[0048] like Figure 1-Figure 6 As shown, the two bag edge folding assemblies 35 are respectively located on both sides of the middle part of the folding positioning seat 31, and each bag edge folding assembly 35 includes a bag edge folding cylinder 351 which is adjustable forward and backward mounted on the folding positioning seat 31, and a bag edge folding sheet 352 which is adjustable upward and downward connected to the output shaft of the bag edge folding cylinder 351 and is located below the bag pressing plate 332.

[0049] like Figure 1-Figure 6As shown, two upper bag corner folding components 36 are respectively located on both sides of the right end of the folding positioning seat 31, and each upper bag corner folding component 36 includes an upper bag corner folding cylinder 361 that can be adjusted forward and backward and mounted on the folding positioning seat 31, and an upper bag corner folding piece 362 that can be adjusted up and down and connected to the output shaft of the upper bag corner folding cylinder 361 and is located below the bag pressing plate 332. Specifically, the two upper bag corner folding pieces 362 are distributed in an "eight" shape.

[0050] Therefore, the present invention provides the bottom folding piece 342, the side folding piece 352 and the upper corner folding piece 362 which can be adjusted horizontally and vertically, so that the folding module 3 can be used to fold pocket fabrics of different sizes and thicknesses, and has a wide range of uses. At the same time, because the bottom folding piece 342, the side folding piece 352 and the upper corner folding piece 362 are adjustable, only one set of molds is needed to replace multiple sets of molds, and when different pocket fabrics need to be processed, the trouble of frequently disassembling and replacing molds is avoided and the use cost is saved.

[0051] like Figure 3 , Figure 4 and Figure 6 As shown, the feeding module 4 includes a feeding positioning seat 41 installed on the frame 1, a movable plate 45 which can move up and down, a feeding upper and lower cylinder 42 which is installed on the feeding positioning seat 41 and is used to drive the movable plate 45 to move up and down, a feeding left and right cylinder 43 which is installed on the movable plate 45, and a feeding template 44 which is located below the bag pressing plate 332 and can be moved left and right by the driving of the feeding left and right cylinders 43; the feeding template 44 can be used to place pocket cloth so that the folding module 3 can perform folding.

[0052] like Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, an "L"-shaped stopper 441 is respectively provided on both sides of the middle of the feeding template 44; one end of the stopper 441 is connected to the side of the feeding template 44, and a stopper groove 442 opening to the left is formed between the other end and the side of the feeding template 44. Therefore, by providing the stopper groove 442, it can be used to limit the pocket fabric when placing the pocket fabric, so as to facilitate the alignment of the pocket fabric. In addition, it can also clamp the two sides of the pocket fabric to a certain extent to prevent it from being easily loosened. Specifically, when using, in the process of placing the pocket fabric, the two sides of the pocket fabric are directly inserted into the two stopper grooves 442, and then the pocket fabric is pushed backward until the ends of the pocket fabric are respectively abutted against the stopper 441. The fabric placement process is simple and convenient, which not only facilitates the positioning of the pocket fabric, but also prevents it from exceeding the preset position.

[0053] like Figure 3 , Figure 4 and Figure 6 As shown, for the loading template 44, both sides of the front end and the middle part can be set as inclined surfaces sloping outward and downward (not marked in the figure), so that after the pocket fabric is placed, the two sides of the pocket fabric can droop more naturally to facilitate the subsequent folding operation.

[0054] An electromagnet (not shown) for cooperating with the feeding template 44 may also be provided on the bag pressing plate 332, so that the electromagnet can be magnetically attracted to the feeding template 44 after being energized, so that the bag pressing plate 332 can be stably and closely attached to the feeding template 44, thereby preventing the pocket fabric from loosening. Of course, the electromagnet will lose its magnetic force after being powered off, so as to loosen the feeding template 44.

[0055] In addition, the feeding and unloading module 5 can be used to transport the workpiece that has completed the folding by cooperating with the folding module 3 and the loading module 4 to the position of the sewing machine head 6 on the workbench 2 for subsequent sewing; the feeding and unloading module 5 can also be used to transport the workpiece that has been sewn by the sewing machine head 6 to the unloading port 21 on the workbench 2 to realize unloading.

[0057] like Figure 3-Figure 6 As shown, bolts for threaded connection with the cylinder body of the bag bottom folding cylinder 341 are passed through the left and right strip holes 311 on the bag bottom, so that the bag bottom folding cylinder 341 can be adjusted left and right. Specifically, when in use, the position adjustment can be achieved by loosening the bolts and then directly moving the bag bottom folding cylinder 341 left and right, and the bag bottom folding piece 342 can be driven to move left and right synchronously. After the adjustment is completed, the bolts can be locked.

[0058] like Figure 3-Figure 6 As shown, bolts for threaded connection with the cylinder body of the bag edge folding cylinder 351 are passed through the front and rear strip holes 312 of each bag edge, so that the front and rear adjustment of the bag edge folding cylinder 351 can be realized; specifically, when in use, the front and rear adjustment can be realized by loosening the bolts and then directly moving the bag edge folding cylinder 351 forward and backward, and the bag edge folding piece 352 can be driven to move forward and backward synchronously, and the bolts can be locked after the adjustment is completed.

[0059] like Figure 3-Figure 6As shown, bolts for threaded connection with the cylinder body of the upper bag corner folding cylinder 361 are passed through the front and rear strip holes 313 of each upper bag corner, so that the upper bag corner folding cylinder 361 can be adjusted forward and backward; specifically, when in use, the front and rear adjustment can be achieved by loosening the bolts and then directly moving the upper bag corner folding cylinder 361 forward and backward, and the upper bag corner folding piece 362 can be driven forward and backward synchronously, and the bolts can be locked after the adjustment is completed.

[0060] like Figure 3-Figure 6 As shown, at the same time, a plurality of scale values ​​314 are arranged on one side of each upper bag corner front and rear strip hole 313, which are sequentially distributed front and back, to show the adjustable range of the upper bag corner folding piece 362; a pointer 315 for matching with the scale value 314 and a handle 316 for conveniently turning the bolt are sleeved on the bolt in each upper bag corner front and rear strip hole 313. In this embodiment, the plurality of scale values ​​314 are divided into various values ​​such as "45 mm", "60 mm", "80 mm" and "100 mm", so that the adjustment range of the upper bag corner folding cylinder 361 can be conveniently and intuitively seen. Therefore, since the upper bag corner folding piece 362 has strict requirements on the movement of the position, after setting the above-mentioned scale values ​​314, the upper bag corner folding piece 362 can be conveniently and accurately moved to prevent it from exceeding the movement stroke.

[0061] like Figure 5 As shown, a bag bottom positioning block (not shown) at the top of the bag bottom folding piece 342 is provided with a bag bottom upper and lower strip hole 343 extending up and down, and a bolt for threaded connection with the output shaft of the bag bottom folding cylinder 341 is passed through the bag bottom upper and lower strip hole 343. When in use, the bag bottom folding piece 342 can be adjusted up and down by simply loosening the bolt and then directly moving it up and down, and then locking the bolt after the adjustment is completed.

[0064] Preferably, for ease of use, the lower end of the quick-release screw 331 is threadedly connected to the first quick-release threaded hole (not shown in the figure) of the edge removal positioning seat 31 and the second quick-release threaded hole (not shown in the figure) of the bag pressing plate 332. Therefore, after the above arrangement, when the quick-release screw 331 is to be disassembled, it can be quickly disassembled by simply twisting it accordingly.

[0065] like Figure 3-Figure 6 As shown, in addition, in order to improve the comfort when twisting the quick-release screw 331 , an adjustment handle 334 is further provided on the top of the quick-release screw 331 .

[0066] In this embodiment, the feeding and unloading module 5 includes a positioning plate 51, a front and rear driving assembly 52 installed on the workbench 2 and used to drive the positioning plate 51 to move forward and backward, and an external pressing and unloading assembly 53 and an internal pressing assembly 54 respectively installed on the positioning plate 51.

[0067] like Figure 7-Figure 11 As shown, the external pressing and blanking assembly 53 includes a pressing block 531 and an external pressing cylinder 532 installed on the positioning plate 51 and used to drive the pressing block 531 to move up and down; the pressing block 531 includes a U-shaped pressing portion 533 and a blanking portion 534 integrally formed on the rear side of the U-shaped pressing portion 533; the external pressing and blanking assembly 53 also includes two external pressing blocks 535 respectively located in the U-shaped pressing portion 533 and distributed front and back, and two external connecting blocks 536 whose two ends are adjustably connected to the U-shaped pressing portion 533 and the external pressing blocks 535; by correspondingly adjusting the external connecting blocks 536 and the external pressing blocks 535, the positions of the two external pressing blocks 535 in the front, back, left and right directions can be adjusted separately. In addition, the unloading portion 534 can be used to push the sewn workpiece backward to the unloading port 21 on the workbench 2 during the synchronous movement with the U-shaped pressing portion 533 to realize unloading, that is, one pressing block 531 can realize two functions at the same time.

[0068] like Figure 7-Figure 11As shown, the internal pressing component 54 includes an air gripper 541, an internal pressing cylinder 542 installed on the positioning plate 51 and used to drive the air gripper 541 to move up and down, two internal positioning seats 543 respectively installed on two clamps of the air gripper 541 and distributed front and back, two internal connecting blocks 544 respectively installed on the two internal positioning seats 543 and distributed front and back and adjustable front and back, and two internal pressing blocks 545 respectively installed on the two internal connecting blocks 544 and adjustable left and right and located between the two external pressing blocks 535; a sewing groove 55 is formed between adjacent external pressing blocks 535 and the internal pressing blocks 545; by correspondingly adjusting the internal connecting blocks 544 and the internal pressing blocks 545, the positions of the two internal pressing blocks 545 in the front, back, left and right directions can be adjusted separately.

[0069] Therefore, after the above-mentioned design of the external pressing and unloading assembly 53 and the internal pressing assembly 54, the structure is not only simple but also has multiple beneficial effects, such as: (1) each external pressing block 535 and internal pressing block 545 can be individually adjusted in the front, back, left and right directions, so that the external pressing block 535 and the internal pressing block 545 can be used to press the sides of pocket fabrics of various sizes after the corresponding position adjustment, so as to facilitate the subsequent cooperation with the sewing machine head 6. (2) Since the two internal pressing blocks 545 are driven by the air claw 541, and because the two clamps of the air claw 51 have no other restrictions, they can be moved closer to or apart from each other without restriction, and then the two internal pressing blocks 545 can also be moved closer to or apart from each other without restriction, and finally the two internal pressing blocks 545 can be suitable for pocket fabrics of various widths. Specifically, as long as the width of the inner pressure block 545 is small enough and the movement stroke of the clamp of the air claw 541 is large enough, the width of the two inner pressure blocks 545 will be small after they are close to each other or the distance between them will be large after they are separated. Therefore, the two inner pressure blocks 545 can be correspondingly applied to pocket fabrics of large or small widths, and the scope of use is very wide. (3) Since there are many combinations of adjustment methods for the outer pressure block 535 and the inner pressure block 545, for example, the outer pressure block 535 and the inner pressure block 545 can be adjusted to be parallel to each other or slightly inclined (such as similar to the shape of an "eight"). In this way, the outer pressure block 535 and the inner pressure block 545 can be used not only for sewing conventionally shaped fabrics, but also for sewing unconventionally shaped fabrics (such as fabrics with two sides in the shape of an "eight"). (4) Since the outer pressing block 535 and the inner pressing block 545 are also adjustable, only one set of molds is needed to replace multiple sets of molds. When processing different pocket fabrics, it not only avoids the trouble of frequent disassembly and replacement of molds, but also greatly saves other mold costs, that is, the cost of use is low. (5) Since the unloading portion 534 and the U-shaped pressing portion 533 are integrally formed, the unloading portion 534 will be driven to move synchronously during the process of the U-shaped pressing portion 533 moving forward and backward; specifically, when the U-shaped pressing portion 534 is in use, while pressing the second workpiece to be sewn and moving backward, the unloading portion 533 will move the first sewn workpiece backward to the unloading port 21 of the workbench 2, thus realizing unloading. It can be seen that this design enables the external pressure cylinder 532 and the front and rear drive components 52 to simultaneously realize the corresponding movement of workpieces in two different processes when they are in action, which has high work efficiency and eliminates the requirement of setting up a separate unloading module, thereby simplifying the overall structure; at the same time, this design not only reduces the cost of the equipment, but also ensures the synchronization of the equipment's actions to avoid asynchronous actions.

[0070] like Figure 7-Figure 11As shown, preferably, each outer pressure block 535 is provided with a plurality of first outer adjustment holes 5351 evenly distributed along the left-right direction, and a plurality of second outer adjustment holes 5331 are evenly distributed around the U-shaped pressing portion 533; each outer connection block 536 is provided with an outer positioning hole 5361 and an outer strip hole 5362 distributed along its length direction; the outer positioning hole 5361 is connected to a first outer adjustment hole 5351 by bolts; the outer strip hole 5362 is connected to a second outer adjustment hole 5331 by bolts. Therefore, after the above holes are set, the outer connection block 536 and the outer pressure block 535 can be adjusted accordingly by simply loosening the corresponding bolts, so as to change the position and direction of the outer pressure block 535, and the adjustment is completed by tightening the bolts after the adjustment is completed.

[0071] like Figure 7-Figure 11 As shown, preferably, each inner positioning seat 543 is provided with a first inner strip hole 5431 extending forward and backward; each inner pressure block 545 is provided with a plurality of first inner adjustment holes 5451 evenly distributed in the left-right direction; each inner connecting block 544 is provided with a second inner adjustment hole 5441 corresponding to the first inner strip hole 5431 and a second inner strip hole 5442 corresponding to the first inner adjustment hole 5451 and extending in the left-right direction; the first inner strip hole 5431 is connected to a second inner adjustment hole 5441 by bolts; the second inner strip hole 5442 is connected to a first inner adjustment hole 5451 by bolts. Similarly, after the above-mentioned holes are provided, the inner connecting block 544 and the inner pressure block 545 can be adjusted accordingly by simply loosening the corresponding bolts, so as to change the position and direction of the inner pressure block 545, and the adjustment is completed by tightening the bolts after the adjustment is completed.

[0072] like Figure 7-Figure 11 As shown, preferably, two first inner strip holes 5431 distributed up and down can be respectively provided on each inner positioning seat 543; each first inner strip hole 5431 is connected to a corresponding second inner adjustment hole 5441 through a bolt. Therefore, since two first inner strip holes 5431 are provided on each inner positioning seat 543, this design can also ensure the connection stability between the inner connection block 544 and the inner positioning seat 543.

[0073] like Figure 7-Figure 11 As shown, preferably, two second inner strip holes 5442 distributed on the left and right are respectively provided on each inner connection block 544; each second inner strip hole 5442 is connected to a corresponding first inner adjustment hole 5451 through a bolt. Therefore, by providing two second inner strip holes 5442 to connect with the inner pressure block 545, the stability between the inner pressure block 545 and the inner connection block 544 can be ensured.

[0074] like Figure 7-Figure 11As shown, preferably, the number of the external connection blocks 536 on each external pressing block 535 can also be set to two, so as to improve the connection stability between the U-shaped pressing portion 533 and each external pressing block 535 and avoid the external pressing block 535 from loosening.

[0075] like Figure 7-Figure 11 As shown, preferably, in order to ensure the movement stability of the pressing block 531, three evenly distributed external pressing cylinders 532 are provided. However, those skilled in the art should know that the number of external pressing cylinders 532 can be increased or reduced according to actual needs.

[0076] Preferably, a first guide assembly and a second guide assembly are respectively provided on the positioning plate 51; the first guide assembly includes a first guide rail mounted on the positioning plate 51 and a first slider mounted on the first guide rail movably up and down and connected to the pressure block 531. The second guide assembly includes a second guide rail mounted on the positioning plate 51 and a second slider mounted on the second guide rail movably up and down and connected to the cylinder of the air claw 541. Therefore, the setting of the first guide assembly can allow the pressure block 531 and the outer pressure block 535 to achieve more stable up and down movement. Similarly, the setting of the second guide assembly can allow the inner pressure block 545 to achieve more stable up and down movement.

[0077] like Figure 7-Figure 11 As shown, preferably, the two ends of each external connection block 536 are respectively connected to the top surface of the U-shaped pressing portion 533 and an external pressing block 535. In addition, each internal connection block 544 is "L"-shaped; the first end of each internal connection block 544 is connected to the internal positioning seat 543, and the second end is connected to the top surface of the internal pressing block 545, that is, the internal pressing block 545 is connected to the internal positioning seat 543 through the internal connection block 544.

[0078] Preferably, the two outer pressing blocks 535 and the two inner pressing blocks 545 are correspondingly in a straight bar shape, an arc shape or a bent shape. Therefore, by setting the outer pressing blocks 535 and the inner pressing blocks 545 in different shapes, sewing grooves 55 of different shapes can be formed between each outer pressing block 535 and the inner pressing block 545, so that they can press the side edges of pocket fabrics of different shapes. For example, when the outer pressing block 535 and the inner pressing block 545 are both in a straight bar shape, the pocket fabrics with straight edges on both sides can be pressed accordingly; and if the outer pressing block 535 and the inner pressing block 545 are both in an arc shape or a bent shape, the pocket fabrics with arc edges or bent edges on both sides can be pressed accordingly. In this embodiment, the two outer pressing blocks 535 and the two inner pressing blocks 545 are all in a straight bar shape.

[0079] like Figure 7-Figure 11As shown, preferably, the cross-section of the blanking portion 534 is rectangular and a through hole (not marked in the figure) is provided in the middle thereof extending upward and downward, so that the blanking portion 534 can be used to press the surroundings of the workpiece, and when the blanking portion 534 presses the workpiece, people can directly observe the condition of the workpiece through the through hole to avoid the situation where the material is stuck but the staff are unaware of it.

[0080] Since the structure of the front and rear drive assembly 52 is prior art, it will not be described in detail here. Meanwhile, since the structure of the sewing machine head 6 is also prior art, it will not be described in detail here.

[0081] The specific use principle of the present invention is introduced below to facilitate understanding of the present invention:

[0082] First, after starting the equipment, place the trouser leg fabric and the pocket fabric on the workbench 2 below the feeding template 44 and on the feeding template 44 respectively;

[0083] Next, the upper and lower folding cylinders 32 drive the folding positioning seat 31 to move downward until the bag pressing plate 332 is covered on the feeding template 44 by the bag pressing groove 333 and the feeding template 44 is magnetically attracted by the energized electromagnet, thereby fixing the pocket fabric;

[0084] Next, the bottom folding cylinder 341, the side folding cylinder 351 and the upper corner folding cylinder 361 are operated in sequence, and synchronously drive the bottom folding piece 342, the side folding piece 352 and the upper corner folding piece 362 to operate in sequence, so as to form folding edges at the bottom, side and upper corner of the pocket fabric;

[0085] Next, the hemming upper and lower cylinders 32 and the feeding upper and lower cylinders 42 respectively drive the hemming positioning seat 31 and the movable plate 45 to move downward correspondingly until the pocket fabric moves to the position of the trouser leg fabric;

[0086] Next, the upper pocket corner folding cylinder 361, the pocket side folding cylinder 351 and the pocket bottom folding cylinder 341 are reset in sequence, so that the folded parts of the pocket fabric are matched and overlapped on the trouser leg fabric;

[0087] Next, the front and rear driving assembly 52 drives the outer pressing and unloading assembly 53 and the inner pressing assembly 54 to move forward to the top of the stacked pocket fabric and trouser leg fabric;

[0088] Next, the outer pressing cylinder 532 and the inner pressing cylinder 542 are respectively operated, so that the four sides of the U-shaped pressing part 533 are pressed on the four sides of the trouser leg fabric; at the same time, the outer pressing block 535 and the inner pressing block 545 are respectively pressed on the corresponding positions of the two side edges of the pocket fabric, so as to position the pocket fabric properly. Of course, there is a sewing groove 55 between the outer pressing block 535 and the inner pressing block 545 for the sewing machine head 6 to perform sewing action;

[0089] Next, the left and right feeding cylinders 43 drive the feeding template 44 to retract so that it leaves the pocket fabric;

[0090] Next, the front and rear drive assembly 52 drives the external material pressing and unloading assembly 53 and the internal material pressing assembly 54 to move backward and drive the cloth to be sewn to move to the bottom of the sewing machine head 6;

[0091] Next, after the sewing machine head 6 has finished sewing a seam along the outer edge of the inner pressing block 545 on both sides of the fabric, the inner pressing cylinder 542 drives the inner pressing block 545 to rise, and then the air claw 541 drives the two inner pressing blocks 545 to approach each other for a certain distance, and then the inner pressing cylinder 542 drives the inner pressing block 545 to descend to the corresponding position of the pocket fabric, and then the sewing machine head 6 sews another seam along the outer edge of the inner pressing block 545;

[0092] Next, after the stitches are sewn, the front and rear drive components 52 continue to drive the outer pressing and unloading components 53 and the inner pressing component 54 forward to move to the position of the next stacked pocket fabric and trouser leg fabric (i.e., the workpiece to be sewn), and the unloading portion 534 at this time is just pressed on the first workpiece that has been sewn. When the front and rear drive components 52 are driven backward later, since the unloading portion 534 has been pressed on the first sewn workpiece, the first sewn workpiece and the workpiece to be sewn will move backward at the same time; and after the workpiece to be sewn moves to the position of the sewing machine head 6, the first sewn workpiece will also move to the unloading port 21 of the workbench 2 at the same time, that is, unloading is realized, and then the sewing machine head 6 can sew the workpiece to be sewn again;

[0093] Next, when the shape of the bag pressing groove 333 is to be changed, the quick release screw 331 is only needed to be loosened, and then other bag pressing plates 332 can be replaced, and the quick release screw 331 can be locked after the replacement is completed;

[0094] Next, when you want to adjust the horizontal positions of the bag bottom folding piece 342, the bag side folding piece 352 and the upper bag corner folding piece 362, loosen the corresponding bolts in the bag bottom left and right strip holes 311, the bag side front and rear strip holes 312 and the upper bag corner front and rear strip holes 313, and then move the corresponding cylinders horizontally, and then lock the bolts after the adjustment is completed;

[0095] Next, when you want to adjust the upper and lower positions of the bag bottom folding piece 342, the bag side folding piece 352 and the upper bag corner folding piece 362, loosen the corresponding bolts in the bag bottom upper and lower strip holes 343, the bag side upper and lower strip holes 353 and the upper bag corner upper and lower strip holes 363, and then move each folding piece up and down accordingly, and then lock the bolts after the adjustment is completed;

[0096] Next, when you want to adjust the outer pressure block 535 and the inner pressure block 545, you can loosen the bolts at the corresponding positions according to the positions you want to adjust to make subsequent adjustments; for example, if the two sides of the pocket fabric are one long and the other short, you only need to loosen the bolts between the inner connecting block 544 and the inner pressure block 545, and then adjust the end of one of the inner pressure blocks 545 to be further to the left than the end of the other inner pressure block 545, so that the two different inner pressure blocks 545 can be pressed against the sides of the pocket fabric of different lengths, and after the adjustment is completed, the bolts are respectively locked in the corresponding holes to complete the adjustment; in addition, you can also loosen the bolts between the outer pressure block 535 and the outer connecting block 536 accordingly, and then adjust the end of one of the outer pressure blocks 535 to be further to the left than the end of the other outer pressure block 535, and after the adjustment is completed, the corresponding bolts are respectively locked in the corresponding holes to complete the adjustment;

[0097] Next, if you want to adjust the width of the sewing groove 55, you only need to loosen the bolts between the outer connecting block 536 and the U-shaped pressing part 533, the bolts between the outer connecting block 536 and the outer pressure block 535, and the bolts between the inner connecting block 544 and the inner positioning seat 543. Then you can adjust the position between the outer pressure block 535 and the inner pressure block 545 in the front-to-back direction to change the size of the sewing groove 55. Moreover, when adjusting, you can also achieve corresponding position adjustment according to the actual stitching style you want to sew. I will not go into details here. After the adjustment is completed, the corresponding bolts are locked in the corresponding holes to complete the adjustment.
