[0042] See also Figures 1 to 3 In an embodiment of the present invention, a correction module 40 is provided for use in a sewing device 100. The sewing device 100 includes a sewing module 20, which is used to sew multiple layers of fabric. The correction module 40 includes a drive assembly 41 and a partition structure 42. The drive assembly 41 is connected to the partition structure 42, and the partition structure 42 includes at least one partition plate. The drive assembly 41 is used to drive the partition structure 42 to move so that each partition plate is inserted into the gap between two adjacent layers of fabric. The at least one partition plate includes at least one first partition plate 421, which is arranged to be tilted upward along the direction of travel of the multiple layers of fabric.

[0043] In the above-mentioned correction module 40, the driving component 41 drives the partition structure 42 to move so that each partition plate is inserted into the gap between two adjacent layers of fabric one by one, and the multiple layers of fabric can be separated without manual operation, and the first partition plate 421 is tilted upward along the direction of travel of the multiple layers of fabric, thereby improving the success rate of the partition plate inserting into the gap between the two layers of fabric to a certain extent, facilitating other subsequent correction operations on the fabric, and thereby improving the efficiency and quality of sewing.

[0044] Specifically, the sewing equipment 100 is a mechanical device used to complete the sewing, embroidery, cutting, ironing and other processing links of clothing, textiles, etc. The sewing equipment 100 includes but is not limited to round neck machines, rib hem machines (overlock hem machines), rib cuff machines (overlock cuff machines), and interlock hem machines. Figure 1 The sewing device 100 can be a round neck machine for sewing a round neck collar strip to the neckline of a coat. The sewing device 100 includes a sewing module 20, which can sew the folded circular round neck collar strip to the body tightly together.

[0045] In the related art, round-neck sewing needs to ensure that the collar height of the entire circle of the garment after sewing meets the pattern requirements of the clothing design, and the maximum deviation cannot exceed a certain deviation, and the deviation value cannot exceed 1mm in most cases. During the round-neck sewing process, the collar strips need to be manually folded and placed on the round-neck machine for sewing. In scenarios where fast operation is required, it is difficult to manually fold the collar strips into a completely aligned state. Coupled with the cutting error of the collar strip pieces, the collar height of the garment (the vertical height from the neckline to the collar tip) will have a large deviation, affecting the sewing quality. Currently, the round-neck machine is equipped with a correction module with the above function. The correction module includes a distribution plate for separating the upper and lower collar strips. During operation, the upper and lower collar strips need to be manually pulled apart before the distribution plate can be controlled to move and inserted into the gap between the upper and lower collar strips. Without manual operation, the distribution plate has a high probability of failure and cannot be inserted into the gap between the upper and lower collar strips, resulting in correction failure, which in turn affects the efficiency and quality of round-neck sewing.

[0046] Optionally, in some embodiments, the sewing device 100 further includes a tensioning and rotating module 30. The fabric is sleeved on the tensioning and rotating module 30, and the tensioning and rotating module 30 can tension the fabric and drive the fabric to rotate. Figure 1 The fabric above the tensioning and rotating module 30 travels from right to left. The sewing module 20 and the deflection correction module 40 are located between the two cloth guide rollers 31 of the tensioning and rotating module 30, with the sewing module 20 located to the left of the deflection correction module 40. When the tensioning and rotating module 30 drives the fabric from right to left, the deflection correction module 40 first corrects the fabric, and then drives the corrected fabric portion to continue to the left to the sewing module 20 for sewing.

[0047] It is understood that in other embodiments, the direction of movement of the fabric above the tensioning and rotating module 30 may be from left to right, and the sewing module 20 may be located to the right of the deflection correction module 40. When the tensioning and rotating module 30 drives the fabric to move from left to right, the deflection correction module 40 first corrects the fabric, and then drives the corrected fabric portion to continue moving rightward to the sewing module 20 for sewing.

[0048] Please combine Figure 2 The sewing device 100 is provided with a fixed base 60. A drive assembly 41 is mounted on the fixed base 60 and connected to the partition structure 42. The drive assembly 41 is configured to drive the partition structure 42 so that each partition plate in the partition structure 42 is inserted into the gap between two adjacent layers of fabric. In one embodiment, the drive assembly 41 drives the partition structure 42 in a forward-backward direction. Optionally, the first drive assembly 41 may include a cylinder 411, the piston rod of which is fixedly connected to the partition structure 42 via a connector 43. When the piston rod is retracted, the partition structure 42 is in an initial position and positioned outside the fabric. When the deflection correction module 40 begins operation, the cylinder 411 is inflated. The compressed air pushes the piston rod outward, driving the partition structure 42 forward, inserting each partition plate into the gap between two adjacent layers of fabric. When the deflection correction module 40 ceases operation, the cylinder 411 is deflated, causing the piston rod to retract, driving the partition structure 42 backward to its initial position, allowing the partition plates to exit the gap between the two fabrics.

[0049] Please combine Figure 3 and Figure 4 At least one partition plate includes at least one first partition plate 421, which is arranged to be tilted upward along the advancing direction of the fabric, that is, the side of the first partition plate 421 closer to the sewing module 20 is higher than the side farther away from the sewing module 20. When the driving assembly 41 drives the first partition plate 421 to contact the fabric, the gap between the two adjacent layers of fabric first contacts the lower side of the first partition plate 421. When the driving assembly 41 drives the first partition plate 421 to continue moving toward the gap, the fabric continues to move in the advancing direction. The gap between the fabrics can gradually expand the contact area of the first partition plate 421 due to the upward tilt of the first partition plate 421, which can reduce the resistance of the fabric to the partition plate to a certain extent, so that the higher left side of the first partition plate 421 also enters the gap, thereby allowing the first partition plate 421 to completely enter the gap between the adjacent two layers of fabric.

[0050] The upward tilt setting along the forward direction of the fabric allows the first partition plate 421 to dynamically adjust its contact angle with the fabric during the insertion process, thereby adapting to slight changes in the gap between two adjacent layers of fabric, and to a certain extent improving the success rate of the first partition plate 421 inserting the gap to separate the two adjacent layers of fabric, thereby facilitating the subsequent correction operations of the correction module 40 on the fabric, thereby improving the efficiency and quality of sewing.

[0051] The number of the first partition plates 421 can be specifically limited according to the number of layers of fabric, and the present invention does not impose any specific limitation on this. In one example, when separating three layers of fabric, please combine Figure 3The number of the first partition plate 421 is 1, and it is located in the middle of the partition structure 40.

[0052] In some embodiments, the multi-layer fabric includes an upper layer of fabric, a middle layer of fabric, and a lower layer of fabric, and the partition structure 42 includes a first partition plate 421, a second partition plate 422, and a bottom plate 423, so that the second partition plate 422 is inserted into the gap between the upper layer of fabric and the middle layer of fabric, the first partition plate 421 is inserted into the gap between the middle layer of fabric and the lower layer of fabric, and the bottom plate 423 supports the lower layer of fabric.

[0053] In this way, the partition structure 42 can completely separate the upper layer of fabric, the middle layer of fabric and the lower layer of fabric, making it difficult for the fabrics to separate from the partition structure 42 and affect the sewing effect, while avoiding contact between the fabrics and affecting the sewing position.

[0054] Specifically, the multi-layer fabric includes an upper layer of fabric, a middle layer of fabric and a lower layer of fabric. Optionally, the upper layer of fabric is a body fabric, and the middle layer of fabric and the lower layer of fabric are two layers of fabric formed by folding the collar strip.

[0055] In the related art, after the current partition structure separates the middle fabric and the lower layer (i.e., the upper and lower layers of the fabric collar strip), there is an open space above the middle fabric and below the lower fabric. In some cases, the fabric is easily detached from the partition structure, affecting the correction effect, and the upper fabric (i.e., the body fabric) is in direct contact with the middle fabric. During the sewing process, the middle fabric is easily touched by the upper fabric, affecting the sewing position, and thus affecting the sewing effect.

[0056] In the embodiment of the present invention, please combine Figure 1 and Figure 2 When the driving assembly 41 drives the partition structure 42 to move, the first partition plate 421 is inserted into the gap between the middle fabric and the lower fabric, that is, the middle fabric is located between the first partition plate 421 and the second partition plate 422, and the lower fabric is located between the first partition plate 421 and the bottom plate 423, so that the upper and lower sides of the middle fabric and the lower fabric are both in a closed space, so the fabric is not easily separated from the partition structure 42.

[0057] At the same time, the second partition plate 422 is inserted into the gap between the upper fabric and the middle fabric, thereby completely separating the upper fabric, the middle fabric and the lower fabric, avoiding contact between the fabrics and affecting the sewing position, and ensuring the sewing effect of the fabrics to a certain extent.

[0058] It is understandable that the surfaces of the first partition plate 421 , the second partition plate 422 and the bottom plate 423 are relatively smooth, which to a certain extent prevents the fabric from encountering resistance when moving relative to the partition structure 42 and affecting the sewing effect and efficiency.

[0059] In some embodiments, the upper surface of the first partition plate 421 is an inclined curved surface.

[0060] In this way, the first partition plate 421 can be more easily inserted into the gap between the middle fabric and the lower fabric to separate the middle fabric and the lower fabric.

[0061] Specifically, please combine Figure 3 and Figure 4 The upper surface of the first partition plate 421 is a curved surface, and is tilted upward along the direction of travel of the multiple layers of fabric, that is, the side close to the sewing module 20 is higher than the side away from the sewing module 20, so that the curved surface has a certain height difference. This height difference makes it possible for the end of the first partition plate 421 close to the fabric to at least partially overlap with the gap between the two adjacent layers of fabric and contact the fabric when it contacts the fabric. The smaller contact area can reduce the resistance encountered by the first partition plate 421 at the moment of insertion into the gap, making it easier for the first partition plate 421 to be inserted into the gap between the middle fabric and the lower fabric.

[0062] As the first partition plate 421 continues to move toward the gap and the fabrics continue to move in the forward direction, the contact area between the gaps between the fabrics and the first partition plate 421 gradually increases, so that the first partition plate 421 completely enters the gap between the middle fabric and the lower layer to separate the middle fabric from the lower layer.

[0063] In some embodiments, the partition structure 42 is provided with a first groove 425 and a second groove 426, the first partition plate 421 and the second partition plate 422 form opposite side walls of the first groove 425, the first partition plate 421 and the bottom plate 423 form opposite side walls of the second groove 426, the sewing device 100 includes a baffle 50, and the partition structure 42 is configured to limit the middle fabric and the lower fabric together with the baffle 50, so that the middle fabric is located between the bottom of the first groove 425 and the baffle 50, and the lower fabric is located between the bottom of the second groove 426 and the baffle 50.

[0064] In this way, the baffle 50 and the partition structure 42 jointly limit the middle fabric and the lower fabric to fix the positions of the fabrics.

[0065] Specifically, please combine Figure 3 and Figure 4The first groove 425 and the second groove 426 of the partition structure 42 are spaced apart along the folding direction (i.e., the vertical direction) of the fabric. The first partition plate 421 and the second partition plate 422 form the opposing side walls of the first groove 425. The first groove 425 is used to accommodate the middle fabric. The opposing side walls of the first groove 425 can restrain the upper and lower sides of the middle fabric to prevent it from escaping from the partition structure 42. The first partition plate 421 and the bottom plate 423 form the opposing side walls of the second groove 426. The opposing side walls of the second groove 426 can restrain the upper and lower sides of the lower fabric to prevent it from escaping from the partition structure 42. Therefore, by restricting the vertical movement of the middle and lower fabrics, the edges of the fabrics can be controlled to produce greater corrective rigidity to cope with more complex situations, such as when the middle and lower fabrics are significantly misaligned, or when the fabrics are made of a harder material and require greater control force.

[0066] Please combine Figure 1 The baffle 50 is arranged opposite to the partition structure 42, so that the fabric is located between the baffle 50 and the partition structure 42, wherein the middle fabric is located between the bottom of the first groove 425 and the baffle 50, and the lower fabric is located between the bottom of the second groove 426 and the baffle 50, so that the baffle 50 and the partition structure 42 jointly limit the positions of the middle fabric and the lower fabric, so that the middle fabric and the lower fabric are respectively accommodated in the first groove 425 and the second groove 426.

[0067] Optionally, in Figure 1 In the middle cloth and the lower cloth are placed on two cloth guide rollers 31. The right cloth guide roller 31 is provided with a limiting groove 31a to accommodate the middle cloth and the lower cloth, thereby limiting the front and rear directions of the middle cloth and the lower cloth to prevent the middle cloth and the lower cloth from falling off the cloth guide roller. Figure 5 The sewing device 100 also includes a ribbed base plate 80 and two sidewall structures 90 located between the partition structure 42 and the right cloth guide roller 31 to further limit the position of the fabric. The ribbed base plate 80 is located below the lower layer of fabric and is used to support the lower layer of fabric; the two sidewall structures 90 are respectively provided on the front and rear sides of the middle fabric and the lower layer of fabric. When the middle fabric and the lower layer of fabric move in the forward direction (from right to left), the two support cylinders 92 can limit the position of the middle fabric and the lower layer of fabric in the front and rear directions to prevent the fabric from falling off. Therefore, when the deviation correction module 40 is working, the multiple partition plates of the partition structure 42 are inserted into the gaps between the corresponding adjacent fabrics, and together with the baffle 50, the fabric is limited and constrained, which can prevent the fabric position from deviating during sewing and ensure the sewing quality to a certain extent.

[0068] In some embodiments, the distance between the baffle 50 and the bottom of the first groove 425 is less than the width of the middle fabric, and the distance between the baffle 50 and the bottom of the second groove 426 is less than the width of the lower fabric.

[0069] In this way, the baffle 50 can push the cloth into the first groove 425 and the second groove 426 due to the width difference to ensure that the position of the cloth is fixed.

[0070] Specifically, please combine Figure 1 , one end of the middle cloth and the lower cloth away from the partition structure 42 abuts against the baffle 50. When the driving assembly 41 drives the partition structure 42 to move so that the middle cloth and the lower cloth are respectively accommodated in the first groove 425 and the second groove 426, since the distance between the baffle 50 and the bottom of the first groove 425 is smaller than the width of the middle cloth, and the distance between the baffle 50 and the bottom of the second groove 426 is smaller than the width of the lower cloth, the middle cloth and the lower cloth are subjected to the squeezing force of the baffle 50. The squeezing force of the baffle 50 pushes the middle cloth and the lower cloth toward the bottom of the first groove 425 and the bottom of the second groove 426, so that the edges of the middle cloth and the lower cloth are close to the first groove 425 and the second groove 426 to ensure that the cloth positions are fixed.

[0071] The distances between the baffle 50 and the bottom of the first groove 425 and the bottom of the second groove 426 can be specifically limited according to actual conditions, and the present invention does not impose any specific limitations on this.

[0072] Optionally, in the stacking direction of the middle fabric and the lower fabric, the bottom of the first groove 425 and the bottom of the second groove 426 are aligned. When the edge of the middle fabric and the edge of the lower fabric respectively abut against the bottom of the first groove 425 and the bottom of the second groove 426, the edge of the middle fabric and the edge of the lower fabric are aligned, which is beneficial to improving sewing quality.

[0073] In some embodiments, the maximum distance between the first partition plate 421 and the second partition plate 422 is smaller than the minimum distance between the first partition plate 421 and the bottom plate 423 .

[0074] In this way, the position of the middle fabric is further restricted to prevent the middle fabric from being separated from between the first partition plate 421 and the second partition plate 422 .

[0075] Specifically, please combine Figure 3 and Figure 4The maximum distance between the first and second partition plates 421, 422 is d1, and the minimum distance between the first and second partition plates 421 and the bottom plate 423 is d2. Optionally, d1 < d2, meaning the distances between the first and second partition plates 421, 422 are both smaller than the distance between the first and second partition plates 421 and the bottom plate 423. The intermediate fabric is positioned between the first and second partition plates 421, 422, which constrain the upper and lower sides of the intermediate fabric. The smaller distance between the first and second partition plates 421, 422 reduces deformation and displacement of the intermediate fabric during movement, preventing it from separating from between the first and second partition plates 421, 422.

[0076] In certain embodiments, the second partition plate 422 includes a protruding portion 422 a that protrudes relative to the first partition plate 421 and the bottom plate 423 .

[0077] In this way, it can be used to receive upper fabrics with a larger area, so that the upper fabrics are not easily separated from the second partition plate 422 .

[0078] Specifically, please combine Figure 2 The second partition plate 422 is located above the first partition plate 421 and is used to support the larger upper layer of fabric. A protrusion 422a is provided on the side of the second partition plate 422 closest to the fabric. This protrusion 422a protrudes relative to the first partition plate 421 and the bottom plate 423, increasing the contact area between the second partition plate 422 and the upper layer of fabric. This provides stable support for the upper layer of fabric and prevents it from detaching or shifting from the second partition plate 422 during handling. This reduces sewing problems caused by detachment or shifting, ensuring sewing quality to a certain extent.

[0079] Optionally, the sewing device 100 also includes a third partition plate 70 for receiving at least part of the upper layer of fabric. The third partition plate 70 is located between the partition structure 42 and the right guide roller 31 of the tensioning and rotating module 30, and is arranged to separate the fabric from the partition structure 42. When the first partition plate 421 of the partition structure 42 is inserted between the middle fabric and the lower fabric, the sewing device 100 can drive the third partition plate 70 to move backward through the screw motor so that the third partition plate 70 is located above the middle fabric, and then the upper fabric is placed on the two guide rollers 31 and located above the third partition plate 70, so that the third partition plate 70 provides stable support for the upper fabric, thereby further improving the sewing quality.

[0080] In some embodiments, the partition structure 42 includes a partition 424 and a second partition plate 422 . The partition plate is provided with a second groove 426 and a notch 424 a . The second partition plate 422 is provided on a side of the notch 424 a away from the second groove 426 to enclose the notch 424 a into a first groove 425 .

[0081] In this way, the upper and lower sides of the middle fabric and the lower fabric are both in a closed space, and the fabrics are not easily separated from the partition structure 42 .

[0082] Specifically, please combine Figure 3 The partition plate is provided with a second groove 426 and a notch 424a. The first partition plate 421 and the bottom plate 423 form two side walls of the second groove 426. The first partition plate 421 forms one side wall of the notch 424a. The top of the first partition plate 421 is an open space. Figure 2 The divider 424 is located below and fixedly connected to the second divider plate 422. The second divider plate 422 is located on the side of the notch 424a facing away from the second groove 426 to enclose the open space above the notch 424a, thereby forming a first groove 425. The second divider plate 422 and the first divider plate 421 serve as the two side walls that enclose the first groove 425. Therefore, when the drive assembly 41 drives the divider structure 42, the middle fabric and the lower fabric are respectively accommodated in the first groove 425 and the second groove 426. The upper and lower sides of the middle and lower fabrics are both enclosed in a closed space, making it difficult for the fabrics to escape from the divider structure 42. At the same time, the upper fabric is located above the second divider plate 422, so that the divider structure 42 can completely separate the upper, middle, and lower fabrics.

[0083] exist Figure 2 In the figure, the driving component 41 is fixedly connected to the second partition plate 422 through the connecting member 43, and the second partition plate 422 is fixedly connected to the partition member 424, so that the driving component 41 is fixedly connected to the partition structure 42. The driving component 41 can drive the partition structure 42 to move so that the partition plate is inserted between two adjacent layers of fabric.

[0084] In some embodiments, the driving assembly 41 is used to drive the partition structure 42 to move downward in an inclined manner so that the partition plate is inserted into the gap between two adjacent layers of fabric.

[0085] In this way, as the partition structure 42 moves downwardly, the partition plate can be guided to be inserted into the gap between two adjacent layers of fabric.

[0086] Specifically, during operation of the deflection correction module 40, the drive assembly 41 drives the partition structure 42 to tilt downward so that the partition plate is inserted into the gap between two adjacent layers of fabric. That is, when the partition plate just contacts the edge of the fabric, the edge of the partition plate is higher than the gap between the fabrics. Furthermore, because the first partition plate 421 is tilted along the direction of travel of the fabrics, with the side closer to the sewing module 20 being higher and the side farther from the sewing module 20 being lower, this height difference allows at least a portion of the edge of the first partition plate 421 to coincide with the gap between the middle fabric and the lower fabric layer, thereby allowing at least a portion of the first partition plate 421 to be inserted into the gap between the middle fabric and the lower fabric layer. As the partition structure 42 tilts downward, the remaining portion of the first partition plate 421 is also guided into the gap, allowing the partition plate to be fully inserted into the gap between the two adjacent layers of fabric.

[0087] Optionally, the installation direction of the drive component 41 is inclined downward relative to the horizontal plane, and the drive component 41 is connected to the partition structure 42 so that the movement direction of the partition structure 42 is consistent with the axis of the drive component 41. The drive component 41 drives the partition structure 42 to move in a straight line in the inclined downward direction, so that the partition plate is inserted into the gap between the two adjacent layers of fabric.

[0088] An embodiment of the present invention provides a sewing device 100 , which includes a sewing module 20 and a deviation correction module 40 according to any one of the above embodiments.

[0089] In the above-mentioned correction module 40, the driving component 41 drives the partition structure 42 to move so that each partition plate is inserted into the gap between two adjacent layers of fabric one by one, and the multiple layers of fabric can be separated without manual operation, and the first partition plate 421 is tilted upward along the direction of travel of the multiple layers of fabric, thereby improving the success rate of the partition plate inserting into the gap between the two layers of fabric to a certain extent, facilitating other subsequent correction operations on the fabric, and thereby improving the efficiency and quality of sewing.

[0090] Specifically, please combine Figure 1 The sewing device 100 includes an operating table 10, which can be used to carry components of the sewing device 100. For example, the sewing module 20 and the correction module 40 can be set on the operating table 10 to work in conjunction with each other.

[0091] Optionally, the sewing device 100 also includes a tensioning and rotating module 30 and a bone-finding module. The fabric is sleeved on the tensioning and rotating module 30, and the tensioning and rotating module 30 can tension the fabric and drive the fabric to rotate. The tensioning module is arranged on one side of the operating table 10, and the sewing module 20 and the correction module 40 are located between the two cloth guide rollers 31 of the tensioning and rotating module 30. The bone-finding module is used to identify and locate the bone position of the fabric (i.e., the edge or specific line of the fabric). When the bone-finding module is working, the tensioning and rotating module 30 drives the fabric to rotate at the same time. After the bone-finding module identifies and locates the bone position of the fabric, the tensioning and rotating module 30 drives the bone position of the fabric to move to the sewing module 20. At this time, the driving component 41 drives the partition structure 42 to move so that each partition plate is inserted into the gap between the two adjacent layers of fabric one by one, thereby separating each layer of fabric, making it easier for the correction module 40 to perform other correction operations on the fabric, thereby improving the efficiency and quality of sewing.

[0092] It is understandable that the above-mentioned correction module 40 can be applied to sewing equipment 100 including but not limited to round collar machines, overlock hem machines, overlock cuff machines, and interlock hem machines that need to separate and align multiple layers of fabric.
