[0035] See also Figures 1 to 4 , a correction module 1000 according to an embodiment of the present invention is used in a sewing device. The sewing device includes a sewing module (not shown). The sewing module is used to sew a first fabric and a second fabric 11. The correction module 1000 includes a first drive assembly 100 and a correction assembly 200. The first drive assembly 100 is connected to the correction assembly 200 through a first transmission member 300. The correction assembly 200 is used to contact the second fabric 11. The first drive assembly 100 is used to control the correction assembly 200 through the first transmission member 300 to drive the second fabric 11 to move so that the edge of the second fabric 11 is located at a preset position 12, so that the sewing module can sew the edges of the first fabric and the second fabric 11.

[0036] In the above-mentioned correction module 1000, the first driving component 100 is used to control the correction component 200 through the first transmission member 300 to drive the second fabric 11 to move so that the edge of the second fabric 11 is located at the preset position 12, so that the sewing module can sew the edges of the first fabric and the second fabric 11, thereby automatically adjusting the edge of the second fabric 11 and ensuring a uniform sewing effect on the edges of the first fabric and the second fabric 11.

[0037] Specifically, the sewing device is used to sew a first fabric (not shown) and a second fabric 11 together. It may include a deflection correction module 1000 and a sewing module. During operation, the deflection correction module 1000 and the sewing module cooperate to sew the first and second fabrics 11 together. Alternatively, the sewing device can be used to sew flat hems, overlock hems, overlock crew necks, flat hems, and upper waistbands.

[0038] It should be noted that in the embodiments of the present invention, the first and second fabrics 11 can refer to two pieces of fabric to be sewn together, or they can refer to different parts of the same piece of fabric. To facilitate understanding of the embodiments of the present invention, the first and second fabrics 11 are merely used to illustrate the embodiments of the present invention and do not constitute a limitation on the scope of protection of the present invention. In actual applications, the correction module 1000 is also suitable for correcting the deviation of a single layer of fabric when sewing to achieve a uniform sewing effect.

[0039] In one embodiment, a sewing device includes a tensioning and rotating module (not shown) and a sewing module. The tensioning and rotating module can be used to tension and rotate a first fabric and a second fabric 11 that is sleeved on the first fabric, and the sewing module is used to sew the first and second fabrics 11 together. Optionally, the tensioning and rotating module can include a first roller (not shown) and a second roller (not shown), and the first and second fabrics 11 can be sleeved on the first and second rollers in sequence. Optionally, the sewing module can include a separator 500 for separating the first and second fabrics 11 and supporting the second fabric 11 during sewing.

[0040] In one embodiment, the deviation correction component 200 is in contact with the second fabric 11. The first drive component 100 is connected to the deviation correction component 200 via the first transmission member 300. When the first drive component 100 is in operation, the deviation correction component 200 can be controlled by the first transmission member 300 to drive the second fabric 11 to move, so that the edge of the second fabric 11 is located at the preset position 12, so that when the sewing module sews the edges of the first fabric and the second fabric 11, a uniform sewing effect is guaranteed to a certain extent. Optionally, the first drive component 100 may include a first motor. Optionally, the first transmission member 300 may include but is not limited to a conveyor belt, a gear, etc. As the first fabric and the second fabric 11 are continuously fed to the sewing module, the sewing module can pass the suture through the first fabric and the second fabric 11 to form a lock or chain stitch, so that the edges of the first fabric and the second fabric 11 are sewn together. The preset position 12 can be set on the sewing path before the sewing module sews the first fabric and the second fabric 11 together, thereby preventing misalignment and uneven seams when sewing the second fabric 11 and the first fabric to a certain extent, thereby improving the sewing effect. Optionally, the sewing path corresponds to the position where the stitch is formed and extends along the direction of fabric feeding.

[0041] In one embodiment, the web correcting module 1000 may include a web correcting sensor, which may be used to detect the edge position of the second fabric 11 .

[0042] In one embodiment, the deflection correction sensor may include a photoelectric sensor. The photoelectric sensor may include a light emitter and a light receiver. The light emitter can emit light toward the set position 13, and the light receiver can receive the light reflected from the set position 13. When the second fabric 11 is located at the set position 13, part of the light is blocked, and the light receiver detects a change in light intensity. When the second fabric 11 is located outside the set position 13, light is reflected back to the light receiver normally.

[0043] In one embodiment, please combine Figure 4 The photoelectric sensor emits a light beam toward the set position 13. When a change in the beam intensity is detected, the correcting assembly 200 is controlled to move the second fabric 11 in a second direction away from the set position 13. When no change in the beam intensity is detected, the correcting assembly 200 is controlled to move the second fabric 11 in the second direction toward the set position 13. This process is repeated, causing the edge of the second fabric 11 to oscillate at different times at the set position 12. This achieves dynamic stability while allowing for more precise control of the position of the edge of the second fabric 11. The second direction is perpendicular to the feeding direction of the second fabric 11 and parallel to the partition plate 500. It should be noted that the set position 12 is a position within the vicinity of the set position 13. Controlling the second fabric 11 to move away from or toward the set position 13 in the second direction can ensure that the edge of the second fabric 11 is located at the set position 12.

[0044] In one embodiment, please combine Figure 3 The photoelectric sensor can emit two light beams, respectively, toward two set positions 13. The distance between the two set positions 13 along the second direction is greater than zero, and the preset position 12 is located between the two set positions 13. When a change in the intensity of both light beams is detected, the web-correcting assembly 200 is controlled to move the second fabric 11 in the second direction so that the edge of the second fabric 11 is located between the two set positions 13, that is, the edge of the second fabric 11 is located at the preset position 12. When no change in the intensity of either light beam is detected, the web-correcting assembly 200 is not controlled to move the second fabric 11 in the second direction, thereby maintaining the edge of the second fabric 11 at the preset position 12. Optionally, the distance between the two set positions 13 along the feeding direction of the second fabric 11 is greater than or equal to zero. Optionally, the distance between the two set positions 13 along the second direction is greater than or equal to 1 mm and less than or equal to 2 mm. It should be understood that the dashed box represents the second fabric 11 with an edge outside the preset position 12.

[0045] It can be understood that the distance between the two set positions 13 along the second direction is greater than zero, and the preset position 12 is located between the two set positions 13, which can make the range of the preset position 12 larger, thereby avoiding the vibration of the sewing equipment caused by the correction component 200 frequently adjusting the edge of the second fabric 11 to a certain extent, and at the same time, it can avoid the false detection problem caused by the protrusion of the seam to a certain extent, thereby improving the stability of the sewing equipment and the sewing quality.

[0046] In one embodiment, in the feeding direction of the second fabric 11, the set position 13 can be closer to the sewing module than the correction component 200, thereby ensuring to a certain extent that the second fabric 11 is located at the preset position 12 when the sewing module sews the first fabric and the second fabric 11.

[0047] In some embodiments, please combine Figure 1 and Figure 2 The first driving component 100 includes a connecting component 101, and the first transmission member 300 is connected to the correcting component 200 through the connecting component 101. The first transmission member 300 drives the correcting component 200 to move along the first direction and the second direction through the connecting component 101. The first direction and the second direction are perpendicular to each other and are both perpendicular to the feeding direction of the second cloth 11.

[0048] In the above embodiment, the first transmission member 300 is connected to the correction component 200 through the connecting component 101. The first transmission member 300 drives the correction component 200 to move along the first direction and the second direction through the connecting component 101, so that the correction component 200 can contact the second fabric 11 for correction. At the same time, in the non-correction state, the interference with the sewing process is reduced.

[0049] Specifically, the first direction is perpendicular to the feeding direction of the second cloth 11 and perpendicular to the partition plate 500 . The second direction is perpendicular to the feeding direction of the second cloth 11 and parallel to the partition plate 500 .

[0050] When the first driving assembly 100 is in operation, the first transmission member 300 and the connecting assembly 101 can be used to control the deviation-correcting assembly 200 to drive the second cloth 11 to move along the second direction.

[0051] In one embodiment, the first transmission member 300 drives the correcting assembly 200 to move in a first direction toward the second fabric 11 through the connecting assembly 101 to contact the second fabric 11. The first transmission member 300 drives the correcting assembly 200 to move in a second direction through the connecting assembly 101 to drive the second fabric 11 to move in the second direction so that the edge of the second fabric 11 is located at the preset position 12.

[0052] In one embodiment, the first transmission member 300 drives the correcting assembly 200 to move in the first direction away from the second fabric 11 via the connecting assembly 101. Optionally, when the correcting of the second fabric 11 is complete or no further correcting is required, the correcting assembly 200 can move in the first direction away from the second fabric 11 to prepare for the next correcting operation, thereby avoiding unnecessary friction or interference caused by continuous contact to a certain extent.

[0053] In some embodiments, please combine Figure 1 and Figure 2 The connecting component 101 includes a camshaft 1011, a first connecting plate 1013 and a second connecting plate 1014. The camshaft 1011 is connected to the correcting component 200 through the first connecting plate 1013 and the second connecting plate 1014. The camshaft 1011 is used to drive the first connecting plate 1013 and the correcting component 200 to move in the first direction under the drive of the first transmission member 300, and to drive the second connecting plate 1014 and the correcting component 200 to move in the second direction under the drive of the first transmission member 300.

[0054] In the above embodiment, the camshaft 1011 is connected to the correction component 200 through the first connecting plate 1013 and the second connecting plate 1014. The camshaft 1011 is used to drive the first connecting plate 1013 and the correction component 200 to move in the first direction under the drive of the first transmission member 300, and to drive the second connecting plate 1014 and the correction component 200 to move in the second direction under the drive of the first transmission member 300. The movement can be transmitted to the correction component 200, and the correction component 200 can be controlled more accurately.

[0055] Specifically, the first driving assembly 100 may include a first driving member 104, and the first driving member 104 may be connected to the correcting assembly 200 via the first transmission member 300 and the connecting assembly 101. Optionally, the first driving member 104 may include a first motor.

[0056] In one embodiment, when the first driving member 104 is in operation, the first transmission member 300 can drive the connecting assembly 101 to drive the deviation-correcting assembly 200 to move along the first direction and the second direction.

[0057] In one embodiment, the connecting assembly 101 includes a camshaft 1011 and a first active synchronous gear 1012. The first driving member 104 can be connected to the first active synchronous gear 1012, and the first transmission member 300 can be mounted on the camshaft 1011 and the first active synchronous gear 1012. When the first driving member 104 is in operation, it can drive the first active synchronous gear 1012 to rotate, thereby driving the camshaft 1011 to rotate through the first transmission member 300.

[0058] The camshaft 1011 is connected to the correcting assembly 200 via a first connecting plate 1013 and a second connecting plate 1014. In one embodiment, the camshaft 1011 is connected to the first connecting plate 1013, which is in turn connected to the second connecting plate 1014 and the correcting assembly 200, while the second connecting plate 1014 is connected to the correcting assembly 200. When the camshaft 1011 rotates, it moves the first connecting plate 1013, thereby moving the correcting assembly 200 in a first direction, while simultaneously moving the second connecting plate 1014, thereby moving the correcting assembly 200 in a second direction.

[0059] In some embodiments, please combine Figure 1 and Figure 2 The first driving component 100 includes an elastic member 102 , one end of the elastic member 102 is connected to the correcting component 200 , and the other end is connected to the first connecting plate 1013 .

[0060] In the above embodiment, one end of the elastic member 102 is connected to the correcting assembly 200, and the other end is connected to the first connecting plate 1013. When the correcting assembly 200 approaches the second fabric 11 along the first direction to correct the second fabric 11, it is further ensured that the correcting assembly 200 can contact the second fabric 11, thereby improving the effectiveness of the correction.

[0061] Specifically, in one embodiment, the correction component 200 is provided with a limiting portion 204. When the camshaft 1011 rotates, it can drive the first connecting plate 1013 to move. When the first connecting plate 1013 moves in the first direction, when the first connecting plate 1013 moves away from the second fabric 11, the first connecting plate 1013 can abut against the limiting portion 204, and at the same time, the correction component 200 is driven to move along the first direction away from the second fabric 11 through the limiting portion 204.

[0062] In one embodiment, the first connecting plate 1013 connects the camshaft 1011 and the correcting assembly 200. When the camshaft 1011 rotates, it drives the first connecting plate 1013 to move. During the movement of the first connecting plate 1013 in the first direction, when the first connecting plate 1013 approaches the second fabric 11, the first connecting plate 1013 moves away from the limiting portion 204. Simultaneously, under the action of gravity, the correcting assembly 200 moves along the first direction toward the second fabric 11.

[0063] The elastic member 102 is arranged along the first direction. One end of the elastic member 102 is connected to the deviation-correcting assembly 200 , and the other end is connected to the first connecting plate 1013 .

[0064] When the camshaft 1011 rotates, it drives the first connecting plate 1013 to move. As the first connecting plate 1013 moves in the first direction and approaches the second fabric 11, the elastic member 102 is stretched, generating an elastic force in the first direction. This elastic force, combined with gravity, causes the correcting assembly 200 to move in the first direction toward the second fabric 11. It will be appreciated that the elastic member 102 can further ensure, to a certain extent, that the correcting assembly 200 moves in the first direction toward the second fabric 11.

[0065] In some embodiments, please combine Figure 1 and Figure 2 The correcting assembly 200 includes a first correcting assembly 201 and a second correcting assembly 202. The first transmission member 300 is connected to the first end of the camshaft 1011. The first correcting assembly 201 is connected to the first end of the camshaft 1011, and the second correcting assembly 202 is connected to the second end of the camshaft 1011. The first transmission member 300 is used to drive the first correcting assembly 201 and the second correcting assembly 202 to alternately contact the second cloth 11 through the connecting assembly 101 to control the edge position of the second cloth 11.

[0066] In the above embodiment, the first transmission member 300 is used to drive the first correcting component 201 and the second correcting component 202 to alternately contact the second fabric 11 through the connecting component 101 to control the edge position of the second fabric 11, thereby achieving continuous and stable correction control, avoiding response lag or deviation accumulation problems to a certain extent, and improving the correction accuracy.

[0067] Specifically, in one embodiment, the sewing device may include a third drive assembly (not shown), which may be used to drive the correction module 1000 to move along the first direction, thereby moving the correction module 1000 closer to or farther from the partition plate 500. Optionally, the third drive assembly includes a pneumatic device (cylinder).

[0068] In one embodiment, before starting to sew the first and second fabrics 11, the third drive assembly can drive the correcting module 1000 to move in the first and second directions so that the correcting assembly 200 contacts the second fabric 11. After starting to sew the first and second fabrics 11, the first drive assembly 100 can drive the correcting assembly 200 to move in the first and second directions to adjust the position of the edge of the second fabric 11.

[0069] In one embodiment, the camshaft 1011 includes a first end and a second end opposite to each other in the feeding direction of the second cloth 11. The first transmission member 300 can be sleeved on the first end of the camshaft 1011, and the first driving member 104 can drive the camshaft 1011 to rotate via the first transmission member 300 when in operation.

[0070] In one embodiment, the first correcting component 201 and the second correcting component 202 may respectively include a main body 203, and the surface of the main body 203 facing the first connecting plate 1013 is provided with a first slide rail 2031. Correspondingly, the first connecting plate 1013 is provided with a first slider (not shown), and the first connecting plate 1013 and the first correcting component 201 are slidably connected through the first slide rail 2031 and the first slider.

[0071] In one embodiment, the connection assembly 101 may include two second connection plates 1014, and the surfaces of the two second connection plates 1014 facing the first connection plate 1013 are provided with third slide rails 1014a. Correspondingly, the first connection plate 1013 is provided with a third slider 1013a. The first connection plate 1013 and the second connection plate 1014 can be slidably connected via the third slider 1013a and the third slide rails 1014a. It is understood that when the first connection plate 1013 moves in the first direction, the third slider 1013a can slide along the third slide rails 1014a, thereby preventing the second connection plate 1014 from moving in the first direction due to the first connection plate 1013 to a certain extent.

[0072] In one embodiment, the correction module 1000 includes a mounting support plate 400, and a second slide rail 401 is provided on the surface of the mounting support plate 400 facing the second connecting plate 1014. Correspondingly, the second connecting plate 1014 is provided with a second slider (not shown), and the second connecting plate 1014 and the mounting support plate 400 are slidably connected through the second slider and the second slide rail 401.

[0073] In one embodiment, the two main bodies 203 are respectively provided with two limiting portions 204. When the camshaft 1011 rotates, the first connecting plate 1013 can be driven to move. When the first connecting plate 1013 moves in the first direction, when the first connecting plate 1013 moves away from the second fabric 11, the first connecting plate 1013 can abut against the limiting portion 204, and at the same time, the main body 203 is driven by the limiting portion 204 to move along the first direction away from the second fabric 11, thereby causing the first correcting component 201 or the second correcting component 202 connected to the first connecting plate 1013 away from the second fabric 11 to move along the first direction away from the second fabric 11.

[0074] In one embodiment, the two first connecting plates 1013 can be respectively connected to the first end and the second end of the camshaft 1011 and the two bodies 203. When the camshaft 1011 rotates, it can drive the first connecting plates 1013 to move. During the movement of the first connecting plates 1013 in the first direction, when the first connecting plates 1013 approach the second fabric 11, the first connecting plates 1013 move away from the limiting portion 204. The first connecting plates 1013 slide on the first slide rail 2031 via the first slider. Simultaneously, under the action of gravity, the first or second correcting assembly 201, 202 connected to the first connecting plate 1013 near the second fabric 11 moves along the first direction toward the second fabric 11.

[0075] In one embodiment, the second connecting plate 1014 is connected to the body 203. When the camshaft 1011 rotates, it can drive the first connecting plate 1013 to move. When the first connecting plate 1013 moves clockwise, the first connecting plate 1013 drives the second connecting plate 1014 via the third slider 1013a and the third slide rail 1014a, which drives the body 203 to move in the second direction, thereby causing the first or second correcting assembly 201, 202, which is in contact with the second cloth 11, to move in the second direction toward the second cloth 11.

[0076] In one embodiment, the second connecting plate 1014 is connected to the body 203. When the camshaft 1011 rotates, it can drive the first connecting plate 1013 to move. When the first connecting plate 1013 moves counterclockwise, the first connecting plate 1013 drives the second connecting plate 1014 and the body 203 to move in the second direction via the third slider 1013a and the third slide rail 1014a, thereby causing the first or second correcting assembly 201, 202 in contact with the second cloth 11 to move in the second direction away from the second cloth 11.

[0077] In one embodiment, the first driving assembly 100 may include two elastic members 102, and the connecting assembly 101 may include two first connecting plates 1013. The two elastic members 102 may connect the two first connecting plates 1013 and the two bodies 203 respectively.

[0078] The elastic member 102 is arranged along a first direction. When the camshaft 1011 rotates, it drives the first connecting plate 1013 to move. During the movement of the first connecting plate 1013 in the first direction, when the first connecting plate 1013 approaches the second fabric 11, the elastic member 102 is stretched, thereby generating an elastic force in the first direction. This elastic force, combined with gravity, causes the body 203 to exert a force on the second fabric 11 in the first direction, thereby causing the first and second correcting assemblies 201, 202 to exert a force on the second fabric 11 in the first direction. It will be appreciated that the elastic member 102 can further ensure that the first and second correcting assemblies 201, 202 move in the first direction toward the second fabric 11 to a certain extent.

[0079] In one embodiment, when the first correcting component 201 moves toward the second fabric 11 along the first direction, the second correcting component 202 moves away from the second fabric 11 along the first direction, thereby enabling the first correcting component 201 and the second correcting component 202 to alternately contact the second fabric 11.

[0080] In some embodiments, please combine Figure 1 and Figure 2 The correcting assembly 200 includes a second driving assembly 205 and a roller 206. The roller 206 is used to contact the second fabric 11. The second driving assembly 205 is connected to the roller 206 and is used to drive the roller 206 to drive the second fabric 11 to move so that the second fabric 11 is delivered to the sewing module.

[0081] In the above embodiment, the correction component 200 includes a second drive component 205 and a roller 206. The second drive component 205 is used to drive the roller 206 to drive the second fabric 11 to move so that the second fabric 11 is delivered to the sewing module, thereby enabling the correction component 200 to control the feeding speed of the second fabric 11, which is beneficial to reducing the space requirement for additional capacity control components.

[0082] Specifically, the roller 206 can be used to contact the second fabric 11. The second drive assembly 205 can drive the roller 206 to rotate, thereby causing the second fabric 11 in contact with the surface of the roller 206 to move under the action of friction and be transported to the sewing module. It will be understood that the friction force on the surface of the second fabric 11 facing the roller 206 is much greater than the friction force on the surface of the second fabric 11 facing away from the roller 206.

[0083] Optionally, the second drive assembly 205 may include, but is not limited to, a motor and a pneumatic device (e.g., a cylinder). In one embodiment, the second drive assembly 205 includes a second drive member 2051, which may include a second motor. The second motor is connected to the roller 206 via a gear to drive the roller 206 to move the second fabric 11, so that the second fabric 11 is delivered to the sewing module. In one embodiment, the second drive assembly 205 includes a second drive member 2051, which may include a second motor. The second motor is connected to the roller 206 via a timing belt 2052 to drive the roller 206 to move the second fabric 11, so that the second fabric 11 is delivered to the sewing module. The second motor can provide a smoother power transmission through the timing belt 2052 while achieving remote transmission, thereby facilitating the flexibility of the sewing equipment layout.

[0084] In one embodiment, the roller 206 is in contact with the second fabric 11. The first drive assembly 100 can control the roller 206 in contact with the second fabric 11 to move in the second direction to drive the second fabric 11. The second drive assembly 205 can drive the roller 206 to rotate, thereby conveying the second fabric 11 to the sewing module. Optionally, the feed speed of the second fabric 11 can be controlled by controlling the rotation speed of the roller 206, so that the feed speed of the second fabric 11 is adapted to the feed speed of the sewing module, thereby achieving capacity control and a capacity sewing effect.

[0085] In one embodiment, a sewing device may include a lower feed dog, which may be located in a sewing module and configured to contact a first fabric. The lower feed dog may rotate to move the first fabric, thereby conveying the first fabric to the sewing module. The sewing module may control the feed speed of the sewing module by controlling the rotational speed of the lower feed dog.

[0086] In one embodiment, the second fabric 11 may include a pulling section, a holding section, and a uniform speed section. Optionally, during the pulling section, the feed speed of the sewing module is greater than or equal to the feed speed of the second fabric 11. During the holding section, the feed speed of the sewing module is less than the feed speed of the second fabric 11. During the uniform speed section, the feed speed of the sewing module is equal to the feed speed of the second fabric 11.

[0087] It is understandable that the correction component 200 can correct the second fabric 11 while controlling the feeding speed of the second fabric 11 to achieve position-controlled sewing, thereby reducing the space requirement for additional position control components.

[0088] In some embodiments, please combine Figure 1 and Figure 2 The second driving assembly 205 includes a second driving member 2051 and a synchronous belt 2052 , and the second driving assembly 205 is connected to the roller 206 via the synchronous belt 2052 .

[0089] In the above embodiment, the second driving member 2051 is connected to the roller 206 via the synchronous belt 2052, which can provide smoother power transmission and realize remote transmission, thereby helping to improve the flexibility of the sewing equipment layout.

[0090] Specifically, the second drive assembly 205 may include a second active synchronous wheel 2053 and a second driven synchronous wheel 2054. The second active synchronous wheel 2053 may be connected to the second drive member 2051, and the second driven synchronous wheel 2054 may be connected to the roller 206. The second synchronous belt 2052 may be mounted on the second active synchronous wheel 2053 and the second driven synchronous wheel 2054. When the second drive member 2051 is in operation, it may drive the second active synchronous wheel 2053 to rotate, thereby driving the second driven synchronous wheel 2054 to rotate via the synchronous belt 2052, and further driving the roller 206 to rotate. Optionally, the second drive member 2051 may include a second motor, the output shaft of which is connected to the first active synchronous wheel 1012.

[0091] It is understood that the second drive assembly 205 controls the rotation of the roller 206 of the correcting assembly 200 via the synchronous belt 2052, allowing the second drive assembly 205 to be positioned away from the correcting assembly 200. This reduces the space occupied by the correcting assembly 200 while ensuring effective correcting and feeding of the second fabric 11, thus optimizing the spatial layout of the correcting module 1000 and reducing its complexity. Furthermore, the second drive assembly 205 can be positioned away from the correcting assembly 200, thereby reducing the space restrictions on its installation, increasing the selectivity of the second drive assembly 205, and thus reducing the cost of the second drive assembly 205.

[0092] In some embodiments, please combine Figure 1 and Figure 2 The first driving assembly 100 includes a cam follower 103 , a camshaft 1011 is provided with an eccentric hole (not shown), the cam follower 103 is provided in the eccentric hole, and the first connecting plate 1013 is connected to the camshaft 1011 through the cam follower 103 .

[0093] In the above embodiment, the first connecting plate 1013 is connected to the camshaft 1011 through the cam follower 103, so that the first connecting plate 1013 moves with the movement of the camshaft 1011, thereby adjusting the edge of the second fabric 11 so that the edge of the second fabric 11 is located at the preset position 12.

[0094] Specifically, in the feeding direction of the second cloth 11, the cam shaft 1011 includes a first end and a second end, each of which is provided with an eccentric hole, and the two eccentric holes are located in two directions symmetrically along the center of the eccentric shaft. A cam follower 103 is provided on each of the two eccentric holes.

[0095] The connecting assembly 101 includes two first connecting plates 1013 , which are respectively connected to two cam followers 103 . When the camshaft 1011 rotates, the camshaft 1011 can drive the two first connecting plates 1013 to move through the cam followers 103 .

[0096] See also Figures 1 to 4 An embodiment of the present invention provides a sewing device. The sewing device includes a tensioning and rotating module, a sewing module, and a deviation correction module 1000 according to any of the above embodiments. The tensioning and rotating module is configured to tension and rotate a first fabric and a second fabric 11 sleeved on the first fabric. The sewing module is configured to sew the first and second fabrics 11. The deviation correction module 1000 is configured to control the edge position of the second fabric 11 so that the edge of the second fabric 11 is located at a preset position 12.

[0097] In the above-mentioned sewing equipment, the correction module 1000 is used to control the edge position of the second fabric 11 so that the edge of the second fabric 11 is located at the preset position 12, thereby automatically adjusting the edge of the second fabric 11 and ensuring a uniform sewing effect on the edges of the first fabric and the second fabric 11.

[0098] Specifically, the sewing device is used to sew together a first fabric and a second fabric 11. It may include a deflection correction module 1000, a tensioning and rotating module, and a sewing module. During operation, the deflection correction module 1000, the tensioning and rotating module, and the sewing module cooperate to sew the first and second fabrics 11, which are sleeved on the tensioning module. Alternatively, the sewing device can be used to sew flat hems, overlock hems, overlock crew necks, flat hems, and upper waistbands.

[0099] Optionally, the tensioning and rotating module may include a first roller and a second roller, and the first and second fabrics 11 may be sequentially mounted on the first and second rollers 206. Optionally, the sewing module may include a partition plate 500 for separating the first and second fabrics 11 and supporting the second fabric 11 when sewing the first and second fabrics 11.

[0100] In one embodiment, the deflection correction assembly 200 is in contact with the second fabric 11. The first drive assembly 100 is connected to the deflection correction assembly 200 via a first transmission member 300. When the first drive assembly 100 is in operation, the deflection correction assembly 200 can be controlled by the first transmission member 300 to drive the second fabric 11, so that the edge of the second fabric 11 is positioned at a predetermined position 12. This ensures a relatively uniform sewing effect when the sewing module sews the edges of the first and second fabrics 11. Optionally, the first drive assembly 100 may include a first motor.

[0101] It is understood that the first drive assembly 100 controls the correcting assembly 200 via the first transmission member 300 to correct the second fabric 11, allowing the first drive assembly 100 to be positioned away from the correcting assembly 200. This effectively corrects the second fabric 11 while reducing the space occupied by the correcting assembly 200, thereby optimizing the spatial layout of the correcting module 1000 and reducing its complexity. Furthermore, the first drive assembly 100 can be positioned away from the correcting assembly 200, thereby reducing installation space constraints for the first drive assembly 100, increasing the selectivity of the first drive assembly 100, and thereby reducing the cost of the first drive assembly 100.

[0102] As the first and second fabrics 11 are continuously fed to the sewing module, the module can thread the sewing thread through the first and second fabrics 11, forming a lockstitch or chain stitch, thereby sewing the edges of the first and second fabrics 11 together. The pre-set position 12 can be located on the sewing path before the sewing module sews the first and second fabrics 11 together. This can primarily prevent misalignment and uneven seams when sewing the second fabric 11 to the first fabric, thereby improving the sewing effect. Optionally, the sewing path corresponds to the position where the stitch is formed and extends along the direction of fabric feed.

[0103] See also Figures 1 to 4 The embodiment of the present invention provides a deviation correction method for the sewing device of the above embodiment, the deviation correction method comprising:

[0104] In the case of sewing the first and second fabrics 11, obtaining the position of the edge of the second fabric 11;

[0105] Determining whether the edge of the second fabric 11 is at a preset position 12;

[0106] If not, the correction module 1000 is controlled to adjust the edge of the second fabric 11 to the preset position 12 .

[0107] If yes, it is determined whether the edge of the second fabric 11 is at the preset position 12 .

[0108] In the above-mentioned correction method, when sewing the first fabric and the second fabric 11, the correction module 1000 is controlled to adjust the edge of the second fabric 11 to the preset position 12, so that the edge of the second fabric 11 can be automatically adjusted, ensuring a uniform sewing effect of the edges of the first fabric and the second fabric 11.

[0109] Specifically, in one embodiment, the sewing device may include a deviation correction module 1000 , and the deviation correction module 1000 may include a deviation correction sensor. The deviation correction sensor may be used to obtain the position of the edge of the second cloth 11 .

[0110] In one embodiment, the deflection correction sensor may include a photoelectric sensor. The photoelectric sensor may include a light emitter and a light receiver. The light emitter can emit light toward the set position 13, and the light receiver can receive the light reflected from the set position 13. When the second fabric 11 is located at the set position 13, part of the light is blocked, and the light receiver detects a change in light intensity. When the second fabric 11 is located outside the set position 13, light is reflected back to the light receiver normally.

[0111] In one embodiment, please combine Figure 4 The photoelectric sensor emits a light beam toward the set position 13. When a change in the beam intensity is detected, the correcting assembly 200 is controlled to move the second fabric 11 in a second direction away from the set position 13. When no change in the beam intensity is detected, the correcting assembly 200 is controlled to move the second fabric 11 in the second direction toward the set position 13. This process is repeated, causing the edge of the second fabric 11 to oscillate at different times at the set position 12. This achieves dynamic stability while allowing for more precise control of the position of the edge of the second fabric 11. The second direction is perpendicular to the feeding direction of the second fabric 11 and parallel to the partition plate 500. It should be noted that the set position 12 is a position within the vicinity of the set position 13. Controlling the second fabric 11 to move away from or toward the set position 13 in the second direction can ensure that the edge of the second fabric 11 is located at the set position 12.

[0112] In one embodiment, please combine Figure 3The photoelectric sensor can emit two light beams, respectively, toward two set positions 13. The distance between the two set positions 13 along the second direction is greater than zero, and the preset position 12 is located between the two set positions 13. When a change in the intensity of both light beams is detected, the web-correcting assembly 200 is controlled to move the second fabric 11 in the second direction so that the edge of the second fabric 11 is located between the two set positions 13, that is, the edge of the second fabric 11 is located at the preset position 12. When no change in the intensity of either light beam is detected, the web-correcting assembly 200 is not controlled to move the second fabric 11 in the second direction, thereby maintaining the edge of the second fabric 11 at the preset position 12. Optionally, the distance between the two set positions 13 along the feeding direction of the second fabric 11 is greater than or equal to zero. Optionally, the distance between the two set positions 13 along the second direction is greater than or equal to 1 mm and less than or equal to 2 mm. It should be understood that the dashed box represents the second fabric 11 with an edge outside the preset position 12.

[0113] It can be understood that the distance between the two set positions 13 along the second direction is greater than zero, and the preset position 12 is located between the two set positions 13, which can make the range of the preset position 12 larger, thereby avoiding the vibration of the sewing equipment caused by the correction component 200 frequently adjusting the edge of the second fabric 11 to a certain extent, and at the same time, it can avoid the false detection problem caused by the protrusion of the seam to a certain extent, thereby improving the stability of the sewing equipment and the sewing quality.

[0114] In one embodiment, in the feeding direction of the second fabric 11, the set position 13 can be closer to the sewing module than the correction component 200, thereby ensuring to a certain extent that the second fabric 11 is located at the preset position 12 when the sewing module sews the first fabric and the second fabric 11.
