[0002] The knitwear production process involves the ribbing process. This involves placing the ribbed and body pieces on a ribbing machine as desired and then sewing them together.

[0068] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0069] As described in the background, a ribbing machine is used to place the ribbed and body panels on a ribbing machine as desired, and then sew the two panels together using the ribbing machine. For ease of description, this application will label either the ribbed or body panel as a first panel 20, and the other as a second panel 30.

[0070] See also Figure 1 and Figure 3 When the automatic sewing equipment 10 is sewing, it is necessary to use the transmission device 300 to tension and transmit the first piece 20 and the second piece 30, and wrap the first piece 20 and the second piece 30 between the two tensioning wheels of the transmission device 300 to form a closed loop, in which one piece is sleeved between the other piece and the tensioning wheel (in this application, it is assumed that the first piece 20 is located between the second piece 30 and the tensioning wheel), and the two tensioning wheels can drive the first piece 20 and the second piece 30 to rotate together around the two tensioning wheels, so that the first piece 20 and the second piece 30 are connected as a whole after sewing by the sewing device 500.

[0071] For ease of description, the definition is as follows Figure 1The XYZ rectangular coordinate system shown in FIG. 1 is a rectangular coordinate system in which the XY plane is parallel to the plane on which the first and second panels 20, 30 are sewn, the X-axis is parallel to the line connecting the centers of the two tensioning pulleys in the transmission device 300, the Y-axis is perpendicular to the X-axis and lies within the XY plane, and the Z-axis is perpendicular to the XY plane. It should be noted that in this application, the X-axis, Y-axis, and Z-axis represent only the horizontal, vertical, and vertical axes, respectively, and do not refer to positive or negative directions.

[0072] like Figure 1 and Figure 2 As shown, the present application proposes an automatic sewing device 10, comprising: a mounting frame 700, which serves to support the other components of the automatic sewing device 10. A sewing device 500, which is used to sew the first and second panels 20, 30, and the sewing device 500 is connected to the mounting frame 700. A transmission device 300, which includes two tensioning wheel parts for tensioning and transmitting the first and second panels 20, 30, and the two tensioning wheel parts include at least one movable tensioning wheel part 320, which is movably connected to the mounting frame 700. A bone position adjustment device 200, which includes at least a pressing plate 210, which can move in the X, Y, and Z axes to adjust the bone position. The panel positioning, clamping, and fixing device 100 is used to clamp and fix the first panel 20 and / or the second panel 30 in a first direction, and / or to move the first panel 20 and / or the second panel 30 in a second direction, wherein the first direction is parallel to the Z-axis and the second direction is parallel to the Y-axis. The blowing device 400 is used to blow the first panel 20 and the second panel 30 straight during the sewing process. The blowing device 400 is connected to the mounting frame 700.

[0073] It can be understood that the sewing device 500 can sew the first piece 20 and the second piece 30 together, and the sewing device 500 can sew, stop the needle, cut the thread, etc. according to the set trajectory, and can automatically realize the sewing process. The sewing device 500 includes various components that can realize the sewing process, and its structure can refer to sewing machines and other equipment.

[0074] It should be noted that joining multiple panels will create a seam at the joining position of the panels, which is called a bone position. The bone position adjustment device 200 is used to adjust the bone position created at the joining of the panels to a specific side to achieve a good appearance and comfortable wearing function.

[0075] It should be noted that the transmission device 300 includes two tensioning wheel parts, one of which can be a movable tensioning wheel part 320, and the two tensioning wheel parts can be moved closer or farther away only by moving the movable tensioning wheel part 320, or both tensioning wheel parts can be movable tensioning wheel parts 320, and the two movable tensioning wheel parts 320 can be moved separately to adjust the distance between the two tensioning wheel parts.

[0076] When it is necessary to use the automatic sewing equipment 10 for sewing, the first piece 20 and the second piece 30 need to be laid on the transmission device 300 first, so that the first piece 20 and the second piece 30 are wound around the transmission device 300. Assuming that the first piece 20 is laid first and then the second piece 30 is laid, after the first piece 20 is laid, the piece positioning, clamping and fixing device 100 is used to fix the first piece 20 in the Z-axis direction to avoid the first piece 20 from being offset when the second piece 30 is laid, affecting the laying efficiency. When the second piece 30 is laid, the fixing effect of the piece positioning, clamping and fixing device 100 on the first piece 20 is cancelled, and the transmission device 300 is turned on, so that the tensioning wheel of the transmission device 300 rotates and drives the first piece 20 and the second piece 30 to rotate around the two tensioning wheels, and decides whether to use the piece positioning, clamping and fixing device 100 to move and adjust the first piece 20 and the second piece 30 in the Y-axis direction according to the positions of the first piece 20 and the second piece 30. Once the positions of the first and second panels 20, 30 are confirmed to be correct, the sewing device 500 is activated to sew the first and second panels 20, 30 together. The skeletal position adjustment device 200 can be used to adjust the skeletal position created by sewing the first and second panels 20, 30 together to a predetermined position. Throughout the sewing process, the blowing device 400 remains activated to straighten the first and second panels 20, 30, preventing curling of the first or second panels 20, 30 and affecting the sewing effect. If the first and second panels 20, 30 become offset during the sewing process, the panel positioning, clamping, and fixing device 100 can be used to adjust the first and second panels 20, 30 in the Y-axis direction.

[0077] In the above scheme, a blowing device 400 is provided to blow the first piece 20 and the second piece 30 straight during the sewing process, thereby preventing the first piece 20 and the second piece 30 from curling during the sewing process, thereby ensuring the sewing quality; a piece positioning, clamping and fixing device 100 is provided to fix the first piece 20 or the second piece 30 when laying it, thereby preventing the first piece 20 or the second piece 30 from shifting when laying the other piece, thereby improving the piece laying efficiency; a transmission device 300 with a movable tensioning wheel part 320 is provided, so that the transmission device 300 can be flexibly adjusted according to the size of the piece to expand the scope of application; a bone position adjustment device 200 is provided to replace manual adjustment of the bone position, thereby realizing automatic adjustment of the bone position, improving the degree of automation of the automatic sewing equipment 10, and ensuring stable sewing quality.

[0078] See also Figure 2 and Figure 4In a specific configuration, an upper deflection-correcting device 600 is further included. The upper deflection-correcting device 600 is movably connected to the mounting frame 700 and includes a mopping wheel 610 that drives the first or second panel 20 or 30 to move in the second direction by contacting the first or second panel 20 or 30; and a rolling drive component 620 that is connected between the mounting frame 700 and the mopping wheel 610 and is configured to drive the mopping wheel 610 to move relative to the mounting frame 700 and / or to rotate the mopping wheel 610 to drive the first or second panel 20 or 30 to move in the second direction. The second direction is the Y-axis direction.

[0079] like Figure 4 As shown, in this embodiment, a sliding mechanism is provided between the upper correcting device 600 and the mounting frame 700. The upper correcting device 600 and the mounting frame 700 are connected by sliding. The upper correcting device 600 can slide relative to the mounting frame 700 in the Y-axis direction, so that the upper correcting device 600 can approach or move away from the first cutting piece 20 and the second cutting piece 30 in the Y-axis direction.

[0080] like Figure 4 and Figure 5 As shown, in a specific setting, the rolling drive component 620 includes a cylinder 621 and a motor 622, wherein the cylinder 621 is used to drive the mop wheel 610 to rotate relative to the mounting frame 700 so that the mop wheel 610 approaches and / or moves away from the first piece 20 or the second piece 30, so that when the first piece 20 or the second piece 30 needs to move in the Y-axis direction, the cylinder 621 can drive the mop wheel 610 to approach and contact the first piece 20 or the second piece 30; the motor 622 is used to drive the mop wheel 610 to rotate to drive the first piece 20 and / or the second piece 30 to move in the Y-axis direction.

[0081] In this embodiment, a belt transmission is adopted between the motor 622 and the mop wheel 610. In actual applications, a gear transmission or the like may also be adopted between the motor 622 and the mop wheel 610.

[0082] like Figure 5 and Figure 6 As shown, further, the upper correcting device 600 also has a plurality of rollers 630, the diameter of the rollers 630 is smaller than the diameter of the mop wheel 610; the plurality of rollers 630 are all connected to the mop wheel 610, the axis of the plurality of rollers 630 is located on the circumferential edge of the mop wheel 610, the radial surfaces of the plurality of rollers 630 are perpendicular to the radial surface of the mop wheel 610, and the peripheries of the plurality of rollers protrude from the periphery of the mop wheel 610.

[0083] It should be noted that the surfaces of the mopping wheel 610 and the smaller roller 630 are smooth to ensure that fine threads on the surface of the first or second panel 20 or 30 are not snagged during movement. The mopping wheel 610 exerts a Y-axis force on the first or second panel 20 or 30 during deflection correction, which creates a certain resistance to movement in the X-axis. If the first or second panel 20 or 30 is knitted, it is susceptible to deformation and stretching, affecting the sewing effect. Therefore, a roller 630 that can rotate along its own center of circle is added to the periphery of the mop wheel 610. When the first piece 20 or the second piece 30 moves in the Y-axis direction, the rolling of the roller 630 and the smooth outer surface of the mop wheel 610 and the roller 630 reduce the friction between the mop wheel 610 and the first piece 20 or the second piece 30 in the X-axis direction, making the transmission of the first piece 20 and the second piece 30 by the transmission device 200 smoother during the sewing process.

[0084] like Figure 4 and Figure 5 As shown, in a specific setting, the upper correcting device 600 also includes a clamping mechanism 640 for fixing the first cutting piece 20 and the second cutting piece 30. The clamping mechanism 640 includes a telescopic cylinder and a support platform connected to the upper correcting device 600. The telescopic cylinder can drive the support platform to move in the Z-axis direction, so that the support platform is close to and / or away from the first cutting piece 20 and the second cutting piece 30, so as to support and fix the first cutting piece 20 or the second cutting piece 30 in the Z-axis direction.

[0085] like Figure 4 and Figure 5 As shown, in one specific configuration, the upper deflection-correcting device 600 also includes a cutter 650 for cutting the sewing thread after sewing is completed. Cutter 650 is connected to the upper deflection-correcting device 600 via a telescopic cylinder. Cutter 650 can move relative to the upper deflection-correcting device 600 in the Y-axis direction to approach and cut the sewing thread. When sewing is complete, the telescopic cylinder extends, allowing cutter 650 to move in the Y-axis direction to approach and cut the sewing thread. After the sewing thread is cut, the telescopic cylinder retracts, causing cutter 650 to retract to its initial position.

[0086] See also Figure 7 and Figure 8In a specific setting, the piece positioning, clamping and fixing device 100 includes: a positioning mechanism 110, the positioning mechanism 110 includes a movable platform 111 that can move between a first position and a second position, and when the movable platform 111 is in the second position, it can fix the first piece 20 or the second piece 30 in the first direction (i.e., the Z-axis direction); a correcting mechanism 120, which is used to drive the first piece 20 and / or the second piece 30 to move along the second direction (i.e., the Y-axis direction), wherein the second direction (i.e., the Y-axis direction) is perpendicular to the first direction (i.e., the Z-axis direction), and the first direction (i.e., the Z-axis direction) and the second direction (i.e., the Y-axis direction) are both perpendicular to the tensioning direction (i.e., the X-axis direction) of the first piece 20 and the second piece 30.

[0087] It is understood that both the positioning mechanism 110 and the clamping mechanism 640 function during the panel placement process, and both function to secure the first panel 20 or the second panel 30 in the first direction (i.e., the Z-axis direction). The two mechanisms mutually enhance the securing effect, achieving a better securing effect. For ease of description, it is assumed that the first panel to be placed is the first panel 20, and the other panel is the second panel 30.

[0088] like Figure 7 and Figure 8 As shown, in this embodiment, the first position and the second position are arranged in a direction perpendicular to the plane of the cutting piece (i.e., the Z-axis direction). It can be understood that the movable table 111 moves between the first position and the second position, and the movable table 111 moves from the first position to the second position to complete the fixing of the first cutting piece 20.

[0089] It should be noted that the deflection correction mechanism 120 is not only used to correct the position of the first panel 20 during the panel laying process, but can also be used to correct the position of the first panel 20 and the second panel 30 during the sewing process. During the sewing process, the first panel 20 and the second panel 30 rotate around the two tensioning pulleys under the action of the tensioning pulleys. At this time, the deflection correction mechanism 120 can be used to correct the position of the first panel 20 and the second panel 30 during the sewing process, preventing the first panel 20 and the second panel 30 from tilting during the sewing process, which would result in poor sewing quality, thereby ensuring sewing quality.

[0090] Furthermore, if Figure 7 As shown, the deflection-correcting mechanism 120 is connected to the movable platform 111. The deflection-correcting mechanism 120 can adjust its contact with the first panel 20 and / or the second panel 30 as the movable platform 111 moves along the Z-axis. Without damaging the first panel 20 and / or the second panel 30, the deflection-correcting mechanism 120 contacts and generates friction with the first panel 20 and / or the second panel 30, thereby achieving synchronous movement of the first panel 20 and / or the second panel 30 through the movement of the deflection-correcting mechanism 120.

[0091] It can be understood that when the friction between the correcting mechanism 120 and the first piece 20 and / or the second piece 30 is too small, the movement of the correcting mechanism 120 cannot drive the first piece 20 and / or the second piece 30. At this time, the position of the correcting mechanism 120 can be adjusted by the movable platform 111 to generate pressure between the correcting mechanism 120 and the first piece 20 and / or the second piece 30, thereby increasing the friction between the correcting mechanism 120 and the first piece 20 and / or the second piece 30, and then realizing the movement of the correcting mechanism 120 to drive the first piece 20 and / or the second piece 30.

[0092] Therefore, although the deflection-correcting mechanism 120 is connected to the positioning mechanism 110 and relies on the positioning mechanism 110 for displacement in the Z-axis direction, it is not limited to being able to contact the first panel 20 and / or the second panel 30 only when the positioning mechanism 110 is in the second position. Specifically, when the deflection-correcting mechanism 120 is used in the panel laying process, the movable platform 111 is in the second position, and the first panel 20 is fixed by the positioning mechanism 110. At this time, the deflection-correcting mechanism 120 can contact the first panel 20 and can use the movement of the deflection-correcting mechanism 120 to drive the first panel 20 to move in the Y-axis. When the deflection-correcting mechanism 120 is used in the sewing process, the positioning mechanism 110 only needs to drive the deflection-correcting mechanism 120 to a position of contact with the first panel 20 or the second panel 30. It is not limited to being in the first position or the second position. However, the position where the deflection-correcting mechanism 120 contacts the first panel 20 or the second panel 30 should be between the first position and the second position.

[0093] In this embodiment, the distance between the correcting mechanism 120 and the first cutting piece 20 or the second cutting piece 30 is smaller than the distance between the positioning mechanism 110 and the first cutting piece 20. At this time, when the correcting mechanism 120 is turned on, the first cutting piece 20 and / or the second cutting piece 30 can be moved and corrected. When the correcting mechanism 120 is closed, the correcting mechanism 120 in contact with the first cutting piece 20 is driven by the positioning mechanism 110 to fix the first cutting piece 20.

[0094] In the above solution, by providing a movable platform 111 capable of moving between a first position and a second position, the positioning mechanism 110 can secure the first panel 20. This allows the positioning mechanism 110 to secure the first panel 20 after it is laid, thus preventing the first panel 20 from shifting when the second panel 30 is laid, thereby improving production efficiency. Furthermore, the above solution also provides a deflection correction mechanism 120 on the movable platform 111. The deflection correction mechanism 120 uses its own movement and the friction between it and the first panel 20 or the second panel 30 to move the first panel 20 or the second panel 30. This allows the first panel 20 and the second panel 30 to be repositioned after they are laid, eliminating the need for re-laying, thereby improving production efficiency.

[0095] Please participate Figure 7 and Figure 8 Furthermore, the positioning mechanism 110 further includes a telescopic mechanism 112, which drives the movable platform 111 to move between a first position and a second position. It is understood that the telescopic mechanism 112 can drive the movable platform 111 from the first position to the second position, and can also move the movable platform 111 from the second position to the first position.

[0096] It is understood that the telescopic mechanism 112 includes at least a telescopic rod and a driving source, which can drive the telescopic mechanism 112 to extend or contract along the Z-axis direction to drive the movable platform 111 to move between the first position and the second position. The driving source can be a pneumatic cylinder or a hydraulic cylinder.

[0097] It is obvious that the movable platform 111 is connected to the telescopic mechanism 112, and can be fixedly connected, detachably connected or integrally formed. Specifically, the movable platform 111 and the telescopic mechanism 112 can be connected by threaded connection, welding or the like.

[0098] See also Figure 8 It should be noted that when the movable platform 111 is in the second position, the movable platform 111 is in contact with the first piece 20, and there is an interaction force between the movable platform 111 and the first piece 20 that is perpendicular to the plane of the first piece 20. In this embodiment, there is an interaction force between the movable platform 111 and the first piece 20 in the Z-axis direction. Figure 7 As shown, when the moving platform 111 is in the first position, the moving platform 111 is not in contact with the first panel 20, and the first panel 20 can move freely.

[0099] See also Figure 7 and Figure 8Furthermore, the positioning mechanism 110 also includes a support platform 113, the position of the support platform 113 is fixed, and is used to cooperate with the movable platform 111 to fix the first cutting piece 20. When the movable platform 111 is in the second position, the movable platform 111 clamps the first cutting piece 20 between the movable platform 111 and the support platform 113.

[0100] It can be understood that the fixed position of the support platform 113 means that the support platform 113 is fixed relative to the mounting frame 700 of the automatic sewing equipment 10. The support platform 113 can be fixed to the mounting frame 700 of the automatic sewing equipment 10, and its fixing method can be one of threaded connection, welding, etc.

[0101] It is obvious that the main function of the support platform 113 is to cooperate with the movable platform 111 to fix the position of the first cut piece 20, and the material and shape of the support platform 113 are not limited. In this embodiment, the support platform 113 is an iron sheet that is threadedly connected to the mounting bracket 700 of the automatic sewing machine 10.

[0102] It is understood that the position of the support platform 113 should be fixed in the moving direction of the movable platform 111 so that the first panel 20 is located between the support platform 113 and the movable platform 111. When the movable platform 111 is in the second position, the first panel 20 is clamped between the support platform 113 and the movable platform 111, and interaction forces are generated between the panel and the support platform 113 and the movable platform 111, thereby increasing the friction between the panel and the support platform 113 and the movable platform 111. This ensures that the first panel 20 cannot move when affected by the second panel 30 when the panels are laid.

[0103] See also Figure 7 Furthermore, the correcting mechanism 120 includes: a correcting member, which is connected to the movable platform 111, and can move relative to the first cutting piece 20 and / or the second cutting piece 30 in a direction parallel to the Y-axis, and contact the first cutting piece 20 and / or the second cutting piece 30, and use friction to drive the first cutting piece 20 and / or the second cutting piece 30 to move; a correcting drive 122, which is used to drive the correcting member to move.

[0104] It can be understood that the correcting member is connected to the movable table 111 so that the correcting member can move as the movable table 111 moves in the Z-axis direction, but the correcting member and the movable table 111 are movably connected so that the correcting member can move in the Y-axis direction relative to the movable table 111.

[0105] The correcting drive 122 serves as the power source of the correcting part. In order to reduce power loss during the power process, the correcting drive 122 can also be connected to the moving platform 111, so that the distance between the correcting drive 122 and the correcting part is smaller, and the power of the correcting drive 122 can be used as much as possible to move the correcting part.

[0106] See also Figure 7 The deviation correction drive 122 includes a driving machine 1211 , a driving wheel 1222 and a driven wheel 1223 , wherein the driving wheel 1222 is connected to the output shaft of the driving machine 1211 .

[0107] It is understandable that the driving machine 1221 can be a power source such as a motor, a heat engine, etc. In this embodiment, the driving machine 1221 is a motor.

[0108] It is understandable that the driving wheel 1222 can be directly connected to the output shaft of the driving machine 1211, or can be indirectly connected to the output shaft of the driving machine 1211 through a gear structure, etc. In this embodiment, the driving wheel 1222 is directly connected to the output shaft of the correction motor.

[0109] See also Figure 7 Furthermore, the deviation-correcting member is a conveyor belt 121, which is connected between the driven wheel 1223 and the driving wheel 1222 and is in a closed loop. The driving wheel 1222 drives the conveyor belt 121 to rotate around the driven wheel 1223 and the driving wheel 1222.

[0110] It can be understood that the conveyor belt 121 rotates around the driven wheel 1223 and the driving wheel 1222 , and the driving wheel 1222 and the driven wheel 1223 should be located on the inner side of the rotation path of the conveyor belt 121 .

[0111] It can be understood that the conveyor belt 121 should be in contact with the first piece 20 and / or the second piece 30. The conveyor belt 121 can be a belt, a chain, etc. In order to protect the surface of the first piece 20 and / or the second piece 30, in this embodiment, the conveyor belt 121 is a belt.

[0112] See also Figure 7 In a specific setting, the number of the driven wheels 1223 is two, and the line connecting the centers of the two driven wheels 1223 and the driving wheel 1222 is a triangular structure.

[0113] It can be understood that when the contact area between the conveyor belt 121 and the first piece 20 and / or the second piece 30 is large, the friction between the conveyor belt 121 and the first piece 20 and / or the second piece 30 is greater, and the pressure per unit area of the first piece 20 and / or the second piece 30 when the conveyor belt 121 drives the first piece 20 and / or the second piece 30 to move is smaller, thereby protecting the surface of the first piece 20 and / or the second piece 30.

[0114] In this embodiment, in order to make the contact area between the conveyor belt 121 and the first cutting piece 20 and / or the second cutting piece 30 larger, any two of the two driven wheels 1223 and one driving wheel 1222 are arranged horizontally along the Y-axis, so that a section of the conveyor belt 121 can contact the first cutting piece 20 and / or the second cutting piece 30.

[0115] It is understood that since the driving wheel 1222 is connected to the deflection correction motor, in order to prevent the deflection correction motor from being located close to the first piece 20 and / or the second piece 30 and affecting the conveyor belt 121 in driving the first piece 20 and / or the second piece 30, in this embodiment, the two driven wheels 1223 are located on the side close to the first piece 20 and / or the second piece 30, and the driving wheel 1222 is located on the side away from the first piece 20 and / or the second piece 30. In other words, the two driven wheels 1223 are arranged horizontally along the Y-axis.

[0116] In other embodiments, the conveyor belt 121 may also be in a non-closed loop. For example, the deflection correction drive 122 includes an unwinding mechanism and a rewinding mechanism, and the two ends of the conveyor belt 121 are respectively connected to the rewinding mechanism and the unwinding mechanism.

[0117] See also Figure 7 In a specific setting, the deviation correction drive 122 also includes a pressure wheel 1224, which presses the conveyor belt 121 from the outer side of the conveyor belt 121.

[0118] It can be understood that the function of the pressure wheel 1224 is to subject the conveyor belt 121 to reverse pressure, thereby tensioning it, so as to prevent the conveyor belt 121 from aging, loosening, and wearing after long-term use, and prevent slipping between the conveyor belt 121 and the driving wheel 1222.

[0119] See also Figure 9 In one specific embodiment, the bone position adjustment device 200 further includes a fixed bracket 230 and a drive mechanism 220 connected between the fixed bracket 230 and the pressing plate 210. The drive mechanism 220 is configured to drive the pressing plate 210 to move in the X, Y, and Z axes. For example, the drive mechanism 220 may include a rack and pinion mechanism in both the X and Y axes, and a screw mechanism in the Z axis, to achieve movement in the X, Y, and Z axes.

[0120] It should be noted that the function of the fixed bracket 230 is to support the pressing plate 210 and the driving mechanism 220. In one specific embodiment, the fixed bracket 230 is fixedly connected to the mounting frame 700 or the sewing device 500 of the automatic sewing equipment 10. In another specific embodiment, the fixed bracket 230 can also be connected to the ground, etc.

[0121] It should be noted that the automatic sewing machine 10 should be equipped with a control system and a bone position detection device. The bone position adjustment device 200 merely serves as an implementation mechanism for the bone position adjustment step. The bone position adjustment device 200 can also be controlled by the control system to achieve automatic bone position adjustment. It is understood that the bone position detection device can detect the position of the bone and output the bone position detection results to the control system. The control system can determine whether the bone position needs to be adjusted based on the bone position detection results. When the bone position needs to be adjusted, the control system can control the bone position adjustment device 200 to adjust the bone position.

[0122] When the bone position is adjusted using the bone position adjustment device 200, the driving mechanism 220 drives the pressing plate 210 to move near the bone position and insert it under the bone position, and then the pressing plate 210 is used to move the bone position to the other side. The rear driving mechanism 220 drives the pressing plate 210 to reset to a position that does not affect the sewing device 500 to perform sewing.

[0123] In the above scheme, a driving mechanism 220 is provided to drive the pressing plate 210 to move in the XYZ three-axis direction, thereby realizing free movement of the pressing plate 210 in the XYZ three-axis direction, that is, the pressing plate 210 can move to any point within the travel range of the driving mechanism 220, and then the driving mechanism 220 and the pressing plate 210 are supported by the fixed bracket 230, filling the gap in the existing automatic sewing equipment 10 that cannot automatically adjust the bone position, improving the degree of automation of the automatic sewing equipment 10, further reducing labor costs, and improving automatic sewing efficiency.

[0124] In one embodiment, a fixing base 240 is connected between the pressing plate 210 and the driving mechanism 220 , and the fixing base 240 can be driven by the driving mechanism 220 to move along the XYZ three-axis directions, thereby realizing the movement of the pressing plate 210 in the XYZ three-axis directions.

[0125] It is understood that the fixing base 240 is disposed between the pressing plate 210 and the driving mechanism 220, and its function is to connect the pressing plate 210 and the driving mechanism 220. It should be noted that the connection between the fixing base 240 and the Z-axis drive 223, and the connection between the fixing base 240 and the pressing plate 210 should both be stable, preferably fixed or detachable.

[0126] like Figure 9As shown, in a specific configuration, the drive mechanism 220 includes a Y-axis drive 221, an X-axis drive 222, and a Z-axis drive 223. The Y-axis drive 221 is connected to the fixed bracket 230; the X-axis drive 222 is connected to the Y-axis drive 221 and can be moved along the Y-axis by the Y-axis drive 221; the Z-axis drive 223 is connected to the X-axis drive 222 and can be moved along the X-axis by the X-axis drive 222. The Z-axis drive 223 can drive the fixed base 240 to move along the Z-axis. The order in which the Y-axis drive 221, X-axis drive 222, and Z-axis drive 223 are connected is not limited to this. In other configurations, the Z-axis drive 223, X-axis drive 222, and Y-axis drive 221 can be connected between the fixed bracket 230 and the fixed base 240, or the X-axis drive 222, Z-axis drive 223, and Y-axis drive 221 can be connected in this order.

[0127] It is understandable that during the use of the bone position adjustment device 200, the pressing plate 210 may be deformed due to excessive force. In this case, in order to ensure that the efficiency of automatic sewing is not affected, any one of the connection methods between the fixing seat 240 and the Z-axis drive 223 and the connection between the fixing seat 240 and the pressing plate 210 can be set to a detachable connection, such as a threaded connection, to facilitate the replacement of the pressing plate 210, so that when the pressing plate 210 is deformed, a new pressing plate 210 can be quickly replaced to avoid affecting the efficiency of automatic sewing.

[0128] In other embodiments, the pressing plate 210 may be directly connected to the Z-axis drive 223 .

[0129] It should be noted that the Y-axis drive 221, the X-axis drive 222, and the Z-axis drive 223 must be installed perpendicular to each other, and the connection between the Y-axis drive 221 and the X-axis drive 222, the connection between the Y-axis drive 221 and the fixed bracket 230, and the connection between the X-axis drive 222 and the Z-axis drive 223 should all adopt a stable connection method, preferably a fixed connection or a detachable connection, which can be welding, threaded connection, etc.

[0130] It can be understood that the Y-axis drive 221, the X-axis drive 222, and the Z-axis drive 223 can adopt any type of drive component that can achieve the telescopic function, such as a telescopic cylinder, an electric push rod, etc. In this embodiment, the Y-axis drive 221, the X-axis drive 222, and the Z-axis drive 223 are all telescopic cylinders.

[0131] Furthermore, the pressed sheet 210 has a sheet-like structure.

[0132] It should be noted that the bone position is a seam formed at the connection position of the pieces when multiple pieces are joined together. Generally, the width of the bone position is narrow and the thickness is slightly larger than the thickness of the pieces. Before the bone position adjustment device 200 adjusts the bone position, the bone position will remain vertical or tilt to either side in a natural state. It is understandable that if the bone position tilts to either side, when the bone position needs to be adjusted, that is, the bone position needs to be adjusted to the other side, the pressing plate 210 needs to be inserted under the bone position first, and then the pressing plate 210 is used to move the bone position to the other side. In order to make it more convenient to insert the pressing plate 210 under the bone position, the pressing plate 210 is set to a sheet shape.

[0133] It should be noted that the thickness of the pressing plate 210 should not be too thin, so as to avoid deformation of the pressing plate 210 after the bone position is adjusted, thereby affecting the next bone position adjustment.

[0134] See also Figure 9 Furthermore, the pressing piece 210 includes: a connecting piece 211, one end of the connecting piece 211 is connected to the fixing seat 240; and a paddle 212, the paddle 212 is connected to the other end of the connecting piece 211, and the paddle 212 is horizontal to the X-axis direction.

[0135] It should be noted that the paddle 212 contacts and adjusts the bone position. The paddle 212 being horizontal to the X-axis means that the paddle 212 is parallel to the plane formed by the X-axis and the Y-axis. This is to ensure that the paddle 212 is parallel to the cut piece in the automatic sewing state, so that the pressing plate 210 can be inserted under the bone position when adjusting the bone position, and to prevent the paddle 212 from being inserted obliquely into the bone position, causing the cut piece to shift or the paddle 212 to break.

[0136] It is understood that the connecting piece 211 is connected between the fixing base 240 and the paddle 212. Its main function is to prevent the paddle 212 from being on the same horizontal plane as the fixing base 240, and to create a height difference between the two in the Z-axis direction. In other words, the paddle 212 is positioned below the fixing base 240, which can prevent the paddle 212 from being interfered with by the fixing base 240 in the Z-axis direction during bone position adjustment, thereby limiting the height of the paddle 212.

[0137] The interference of the fixing seat 240 in the Z-axis direction can be understood as follows: since the thickness of the cutting piece is very thin, and the fixing seat 240 is connected to the pressing plate 210, for example, by welding, there may be some connection areas whose thickness is greater than that of the pressing plate 210, so that when the fixing seat 240 descends, the connection area with a larger thickness has already contacted the cutting piece but the pressing plate 210 cannot be inserted under the bone position; it can also be understood that when the paddle 212 is directly connected to the fixing seat 240, the fixing seat 240 needs to descend to contact or be close to the cutting piece, and then the paddle 212 can be inserted under the bone position, and at this time, movement in the X-axis direction or the Y-axis direction may cause the cutting piece to shift, causing sewing to offset or be stopped.

[0138] It is understood that the connecting piece 211 can be arranged perpendicular to the fixing base 240 or at an angle. When the connecting piece 211 is arranged perpendicular to the fixing base 240, the fixing base 240 is located directly above the paddle 212 in the Z-axis direction, and the paddle 212 should not be interfered with by the fixing base 240 during bone position adjustment. However, if the paddle 212 is shorter in the Y-axis direction, there is still the possibility of interference from the fixing base 240 in the Y-axis direction during bone position adjustment.

[0139] The interference of the fixing seat 240 in the Y-axis direction can be understood as that when the width of the fixing seat 240 in the Y-axis direction is greater than the length of the paddle 212 in the Y-axis direction, when the bone position is located between the fixing seat 240 and other devices of the automatic sewing equipment 10 in the Y-axis direction, the paddle 212 can only move to the position where the fixing seat 240 and other devices of the automatic sewing equipment 10 abut. If the bone position is close to other devices of the automatic sewing equipment 10, when the paddle 212 moves to the position where the fixing seat 240 and other devices of the automatic sewing equipment 10 abut, it still cannot contact the bone position, and the bone position cannot be adjusted.

[0140] Therefore, if Figure 9 As shown, in this embodiment, the connecting piece 211 extends along the Z-axis while also tilting in the Y-axis, forming an obtuse angle with the paddle 212. This ensures that the paddle 212 is not interfered with by the fixing base 240 during bone position adjustment in the Y-axis direction. For example, if the connecting piece 211 is rectangular, its longitudinal ends are connected to the fixing base 230 and the paddle 212, respectively, resulting in a height difference between the fixing base 240 and the paddle 212 in the Z-axis direction. Furthermore, the connecting piece 211 is tilted toward the Y-axis, creating an angle between the length of the connecting piece 211 and the Z-axis direction.

[0141] like Figure 9As shown, in this embodiment, the paddle 212 is positioned below the fixing base 240 on the side proximal to the sewing device 500 of the automatic sewing machine 10. It is understood that the joint is a seam formed by joining multiple panels, and its length varies, but the joint begins at the location of the sewing device 500. Therefore, to accommodate shorter joints, the connecting piece 211 is tilted in the Y-axis direction toward the side proximal to the sewing device 500, so that the paddle 212 is positioned below the fixing base 240 on the side proximal to the sewing device 500. In a specific configuration, the paddle 212 and the fixing seat 240 are located on the same side of the fixing bracket 230. In the Y-axis direction, the connecting piece 211 is configured to be inclined toward the fixing bracket 230 in the Y-axis direction, so that the paddle 212 is closer to the fixing bracket 230 than the fixing seat 240. When the fixing bracket 230 is installed on the automatic sewing machine 10, the paddle 212 is located on the side of the fixing seat 240 closer to the sewing device 500 and below the fixing seat 240.

[0142] Furthermore, the connecting piece 211 and the paddle 212 are formed in an integral structure, and specifically can be formed by die-casting followed by CNC bending or stamping.

[0143] Furthermore, the fixing bracket 230 has an L-shaped structure, including: a vertical plate 232, one end of which is connected to the sewing device 500 of the automatic sewing equipment 10; and a horizontal plate 231, which is fixedly connected to the other end of the vertical plate 232 and is perpendicular to the vertical plate 232.

[0144] See also Figure 9 In this embodiment, a plurality of long grooves 2321 are provided at one end of the vertical plate 232 connected to the sewing device 500. These long grooves 2321 can be adapted to the sewing device 500 to realize a threaded connection, so that the vertical plate 232 can move up and down relative to the sewing device 500 while maintaining a stable connection structure.

[0145] Please continue reading Figure 1 The Y-axis driver 221 is connected to the horizontal plate 231. In order to ensure the stability of the connection between the Y-axis driver 221 and the horizontal plate 231, the horizontal plate 231 extends horizontally at the connection between it and the Y-axis driver 221 to increase the connection area between it and the Y-axis driver 221 and enhance the stability of the connection between it and the Y-axis driver 221.

[0146] It should be noted that a variety of connection methods can be used between the Y-axis drive 221 and the horizontal plate 231. In order to ensure stability between the two, a fixed connection or a detachable connection is preferably used. In this embodiment, a threaded connection is used between the Y-axis drive 221 and the horizontal plate 231.

[0147] Furthermore, a reinforcing plate 233 is connected between the horizontal plate 231 and the vertical plate 232. The reinforcing plate 233 serves to make the connection between the horizontal plate 231 and the vertical plate 232 more stable.

[0148] Generally, since the horizontal plate 231 and the vertical plate 232 are arranged vertically, the connection range is only one side of the horizontal plate 231 or the vertical plate 232, and rotation or deformation is easy to occur between the horizontal plate 231 and the vertical plate 232 when subjected to force. Figure 9 As shown, the driving mechanism 220 is connected to the horizontal plate 231. The gravity of the driving mechanism 220, the fixing seat 240 and the pressing plate 210 produces a downward pulling force on the horizontal plate 231. This pulling force makes the horizontal plate 231 tend to rotate relative to the vertical plate 232, that is, with the connection point between the horizontal plate 231 and the vertical plate 232 as the center of the circle, the horizontal plate 231 and the other end of the vertical plate 232 tend to approach each other. On the other hand, the driving mechanism 220 needs to move the pressing plate 210 relative to the fixed bracket 230 when driving the pressing plate 210 to move. The driving mechanism 220 inevitably has a thrust on the fixed bracket 230. For example, in this embodiment, the Y-axis drive 221 is connected to the horizontal plate 231. When the Y-axis drive 221 drives other components relative to the fixed bracket 230 along the Y-axis drive 221, there is also a corresponding thrust on the horizontal plate 231 in the Y-axis direction. This thrust easily causes the connection between the horizontal plate 231 and the vertical plate 232 to be easily twisted and deformed, that is, the connection between the horizontal plate 231 and the vertical plate 232 is circular, and there is a tendency to rotate in the plane where the horizontal plate 231 is located. Therefore, it is necessary to set a reinforcing plate 233 between the horizontal plate 231 and the vertical plate 232 to improve the bearing capacity of the horizontal plate 231 and the vertical plate 232, so as to avoid the deformation of the fixed bracket 230 during use, which causes the pressing plate 210 to fail to adjust the bone position.

[0149] It is understandable that the structure between the reinforcing plate 233 and the horizontal plate 231 and the vertical plate 232 is not limited, but generally, the reinforcing plate 233 and the horizontal plate 231 and the vertical plate 232 form a triangular structure that is more stable.

[0150] Specifically, the reinforcing plate 233 can be tilted between the horizontal plate 231 and the vertical plate 232 so that a right triangle is formed between the horizontal plate 231, the vertical plate 232 and the reinforcing plate 233. The reinforcing plate 233 is used to support the horizontal plate 231 to avoid rotation between the horizontal plate 231 and the vertical plate 232 during use, thereby affecting the positioning of the pressing plate 210.

[0151] like Figure 9As shown, in this embodiment, the reinforcing plate 233 is a right-angled triangle structure, and the two right-angled sides of the reinforcing plate 233 are fixedly connected to the horizontal plate 231 and the vertical plate 232 respectively. At this time, the reinforcing plate 233 is perpendicular to the horizontal plate 231 and the vertical plate 232. The reinforcing plate 233 is used to support the horizontal plate 231 to avoid rotation between the horizontal plate 231 and the vertical plate 232 during use, thereby affecting the positioning of the pressing plate 210.

[0152] It should be noted that the connection method between the reinforcing plate 233 and the horizontal plate 231 and the vertical plate 232 is not limited, but in order to ensure the stability of the fixing bracket 230, it is preferably a fixed connection, which can be welding.

[0153] When using the bone position adjustment device 200, after the bone position detection device detects the bone position, the control system analyzes the bone position information and raises the sewing needle and built-in presser foot of the sewing device 500. The control system then controls the bone position adjustment device 200 to lower the pressing plate 210 so that it is inserted under the bone position. The pressing plate 210 is then raised and moved in the direction in which the bone position is to be adjusted, thereby completing the bone position adjustment. After the bone position adjustment is completed, the sewing needle and built-in presser foot of the sewing device 500 are lowered, and sewing continues.

[0154] See also Figure 1 、 Figures 10 to 12 In a specific setting method, the blowing device 400 includes: a blowing part 410, which is connected to the mounting frame 700 through a first telescopic mechanism 411, and is used to straighten the first cut piece 20 and the second cut piece 30; a blowing compensation part 420, which is arranged opposite to the blowing part 410 and is connected to the mounting frame 700 through a second telescopic mechanism 421, and is used to straighten the first cut piece 20 and the second cut piece 30 when the blowing part 410 stops blowing.

[0155] It is understood that the purpose of the blowing unit 410 and the blowing compensation unit 420 is to prevent the edge of the cut piece from curling. Generally speaking, curling occurs at the edge of the cut piece and curls inward from the edge of the cut piece. Therefore, the blowing direction of the blowing unit 410 and the blowing compensation unit 420 should include a direction perpendicular to the direction of travel of the cut piece, that is, the blowing direction should include the Y-axis direction.

[0156] It is understood that the blowing compensation portion 420 serves to supplement the blowing effect of the blowing portion 410. It can be used to blow air to the first and second panels 20, 30 when the blowing portion 410 is withdrawn and paused, allowing the first and second panels 20, 30 to straighten under the action of the wind and prevent curling. It should be noted that the blowing compensation portion 420 can also be used alone, for example, in sewing panels for small-sized clothing.

[0157] It is understood that the first telescopic mechanism 411 can drive the blowing portion 410 to move relative to the mounting frame 700, so that the blowing portion 410 moves closer to or farther away from the first panel 20 and the second panel 30 in the Y-axis direction. Similarly, the second telescopic mechanism 421 can drive the blowing compensation portion 420 to move relative to the mounting frame 700, so that the blowing compensation portion 420 moves closer to or farther away from the first panel 20 and the second panel 30 in the Y-axis direction.

[0158] Specifically, if Figure 10 and Figure 11 As shown, in this embodiment, one end of the first telescopic mechanism 411 is fixedly connected to the automatic sewing device 10, and the other end is connected to the blowing part 410, as shown in FIG. Figure 10 As shown, when the first telescopic mechanism 411 is extended, the blowing portion 410 is close to the first and second cutting pieces 20 and 30, as shown in FIG. Figure 2 As shown, when the first telescopic mechanism 411 is shortened, the blowing portion 410 moves away from the first panel 20 and the second panel 30 .

[0159] like Figure 10 As shown, in this embodiment, one end of the second telescopic mechanism 421 is connected to the automatic sewing equipment 10, and the other end of the second telescopic mechanism 421 and the blowing compensation part 420 are both connected to a connecting vertical plate, and the second telescopic mechanism 421 and the blowing compensation part 420 are located on the same side of the connecting vertical plate, so that when the second telescopic mechanism 421 is extended, the blowing compensation part 420 is away from the first piece 20 and the second piece 30, and when the second telescopic mechanism 421 is shortened, the blowing compensation part 420 is close to the first piece 20 and the second piece 30.

[0160] It can be understood that the first telescopic mechanism 411 drives the blowing part 410 and the second telescopic mechanism 421 drives the blowing compensation part 420 to move closer to or away from the first piece 20 and the second piece 30, wherein close or away refers to the relative position of the blowing part 410 or the blowing compensation part 420 and the first piece 20 and the second piece 30 on a plane parallel to the plane where the pieces are located when the first telescopic mechanism 411 or the second telescopic mechanism 421 is extended or shortened. It can be understood that the blowing part 410 or the blowing compensation part 420 is relatively close to or relatively away from the first piece 20 and the second piece 30 when the first telescopic mechanism 411 or the second telescopic mechanism 421 is extended or shortened, and is not limited to the position close to the first piece 20 and the second piece 30 as the position close to the first piece 20 and the second piece 30, nor is it limited to the position away from the first piece 20 and the second piece 30 as the position not in contact with the first piece 20 and the second piece 30.

[0161] Specifically, when the first telescopic mechanism 411 is extended, the blowing portion 410 approaches the first panel 20 and the second panel 30. At this time, the end of the blowing portion 410 farthest from the first telescopic mechanism 411 can be close to the first panel 20 and the second panel 30, or can have exceeded the edge of the first panel 20 or the second panel 30 (the edge near the blowing portion 410), so that the blowing portion 410 is located above or below the first panel 20 and the second panel 30. When the first telescopic mechanism 411 is shortened, the blowing portion 410 moves away from the first panel 20 and the second panel 30. At this time, the end of the blowing portion 410 farthest from the first telescopic mechanism 411 must be retracted to the outside of the edge of the first panel 20 and the second panel 30 so that the blowing portion 410 does not affect the sewing of the first panel 20 and the second panel 30.

[0162] Similarly, when the second telescopic mechanism 421 is extended, the blowing compensation part 420 moves away from the first piece 20 and the second piece 30. At this time, the blowing compensation part 420 can be withdrawn to the outside of the edge of the first piece 20 and the second piece 30 (the edge of one side of the near blowing compensation part 420), or it can still exceed the edge of the first piece 20 or the second piece 30, but withdraw toward the side of the far blowing part 410 when the second telescopic mechanism 421 is shortened.

[0163] It should be noted that the function of the first telescopic mechanism 411 and the second telescopic mechanism 421 is to drive the blowing part 410 or the blowing compensation part 420 to move. They can be telescopic cylinders, electric push rods, etc. In this embodiment, the first telescopic mechanism 411 and the second telescopic mechanism 421 are both telescopic cylinders.

[0164] In the above scheme, by setting the blowing compensation part 420 which is arranged opposite to the blowing part 410, the blowing part 410 can be replaced by the blowing part 410 to continue to blow the first piece 20 and the second piece 30 straight after the blowing part 410 is withdrawn, without affecting the continued sewing of the first piece 20 and the second piece 30, so that the first piece 20 and the second piece 30 can always be kept without curling during the sewing process, thereby improving the sewing quality, ensuring the stability of the sewing quality, and reducing the defective rate.

[0165] See also Figure 4 The blowing device 400 further includes a sensing device 430 for sensing the distance between the stitched portions of the first and second panels 20 and 30 and the blowing portion 410 .

[0166] Specifically, the function of the sensing device 430 is to sense the distance between the stitched parts of the first and second panels 20 and 30 so that when the blowing unit 410 may affect the stitching of the first and second panels 20 and 30, the blowing unit 410 can be withdrawn in time.

[0167] Specifically, sensing device 430 can be a contact sensor, whose contacts are activated by the contact and compression of two objects. Common examples include limit switches and two-dimensional matrix position sensors. When a moving object strikes a limit switch, its internal contacts activate, thereby achieving control. During use, sensing device 430 can be positioned between first and second panels 20, 30. When a stitched portion of first and second panels 20, 30 approaches sensing device 430, the stitched portion will contact sensing device 430, causing sensing device 430 to emit a signal.

[0168] The sensing device 430 can also be a proximity switch, which emits an "action" signal when an object approaches a set distance from it, without requiring direct contact with the object. There are many types of proximity switches, including electromagnetic, photoelectric, differential transformer, eddy current, capacitor, reed switch, and Hall effect types. During use, the set distance is the distance between the blowing unit 410 and the stitched portion of the first and second panels 20, 30, which may affect the sewing of the first and second panels 20, 30. When the stitched portion of the first and second panels 20, 30 reaches the set distance, the sensing device 430 emits a signal.

[0169] Furthermore, the blowing device 400 also includes an adjustment device that controls the extension and / or contraction of the first and second telescopic mechanisms 411 and 421 based on the sensing result of the sensing device 430. Specifically, when the adjustment device receives a signal from the sensing device 430, the adjustment device controls the first telescopic mechanism 411 to contract so that the blowing portion 410 moves away from the first and second panels 20 and 30. At this time, the end of the blowing portion 410 farther from the first telescopic mechanism 411 must be retracted to the outside of the edge of the first and second panels 20 and 30 so that the blowing portion 410 does not affect the sewing of the first and second panels 20 and 30. The adjustment device controls the second telescopic mechanism 421 to contract so that the blowing compensation portion 420 moves closer to the first and second panels 20 and 30, thereby taking over from the blowing portion 410 and continuing to straighten the first and second panels 20 and 30 without affecting the continued sewing of the first and second panels 20 and 30.

[0170] See also Figure 3 、 Figure 11 and Figure 12 In a specific setting, the blowing part 410 includes an upper blowing plate 412 and a lower blowing plate 413 arranged in parallel. The upper blowing plate 412 and the lower blowing plate 413 are respectively located above the first cut piece 20 and the second cut piece 30 when the blowing part 410 is in the blowing state.

[0171] like Figure 3As shown, in this embodiment, on the plane where the sewing device 500 is located, the first panel 20 is located below the second panel 30, that is, the first panel 20 is located between the second panel 30 and the tensioning wheel. At this time, the upper air blowing plate 412 is located above the second panel 30, and the lower air blowing plate 413 is located above the first panel 20, that is, the lower air blowing plate 413 is located between the first panel 20 and the second panel 30.

[0172] See also Figure 12 Furthermore, the upper air blowing plate 412 and the lower air blowing plate 413 are both provided with an air inlet 414 and an air outlet 415 , and a ventilation duct for connecting the air inlet 414 and the air outlet 415 is provided inside the upper air blowing plate 412 or the lower air blowing plate 413 .

[0173] It will be appreciated that the air inlet 414 is intended to admit the air necessary to straighten the first or second panel 20, 30. The air inlet 414 should be connected to a device capable of supplying air, such as a blower via an air duct. The ventilation duct connects the air inlet 414 and the air outlet 415, conveying the air from the air inlet 414 to the air outlet 415. The air outlet 415 directs the air toward the first or second panel 20, 30, preventing the first or second panel 20, 30 from curling due to the wind.

[0174] It should be noted that if Figure 12 As shown, the air outlet 415 can be provided on the upper surface or lower surface of the upper air blowing plate 412 or the lower air blowing plate 413. However, in order to achieve the best blowing effect of the air blowing portion 410, the blowing direction should be parallel to the plane where the first panel 20 or the second panel 30 is located. Therefore, the upper air blowing plate 412 and the lower air blowing plate 413 can be provided with a blowing tab with a side wall opening to adjust the blowing direction. The blowing tab covers the air outlet 415, and the hollow interior of the blowing tab allows the side wall opening to communicate with the air outlet 415, thereby adjusting the blowing direction to be parallel to the plane where the first panel 20 or the second panel 30 is located. In addition, the blowing tab can be configured to rotate relative to the air outlet 415, so that the direction can be adjusted on a plane parallel to the plane where the first panel 20 or the second panel 30 is located by rotating the blowing tab.

[0175] See also Figure 10 The blowing compensation portion 420 includes a blowing plate 422 , and the blowing plate 422 is provided with an air outlet unit, and the blowing direction of the air outlet unit is toward the blowing portion 410 .

[0176] It can be understood that since the blowing compensation part 420 and the blowing part 410 are arranged relative to each other, and the cut piece is located between the blowing compensation part 420 and the blowing part 410, the blowing direction of the blowing compensation part 420 is toward the direction of the blowing part 410, that is, toward the cut piece.

[0177] It can be understood that the function of the air outlet unit is to make the wind blow toward the first cut piece 20 or the second cut piece 30. The structure of the air outlet unit can be similar to the upper air blowing plate 412 or the lower air blowing plate 413, and an air inlet 414, an air outlet 415 and a ventilation duct connecting the air inlet 414 and the air outlet 415 are provided. Ventilation can also be directly carried out in the blowing direction through the air outlet pipe 423.

[0178] See also Figure 10 In this embodiment, the air outlet unit includes an air outlet pipe 423 externally disposed on the air blowing plate 422 , and the air outlet pipe 423 is fixedly connected to the upper surface of the air blowing plate 422 .

[0179] It can be understood that one end of the air outlet pipe 423 is facing the blowing direction, and is used to blow air toward the first piece 20 and the second piece 30 to prevent the first piece 20 or the second piece 30 from curling. The other end of the air outlet pipe 423 should be connected to a device that can input air, such as a blower connected through an air supply duct.

[0180] It can be understood that the air outlet pipe 423 is fixedly connected to the blowing plate 422, which means that the air outlet pipe 423 can move synchronously with the blowing plate 422, and is relatively stationary without displacement. The connection method can be gluing, welding, snap connection, etc. In this embodiment, the air outlet pipe 423 is welded to the blowing plate 422.

[0181] like Figure 10 and Figure 11 As shown, in this embodiment, the air outlet pipe 423 is L-shaped, and one end of the air outlet pipe 423 is located on the upper surface of the blowing plate 422, and is used to blow air toward the first cut piece 20 and the second cut piece 30. The other end of the air outlet pipe 423 passes through the blowing plate 422 and is located on the lower surface of the blowing plate 422, and is used to connect a device that can input air.

[0182] See also Figure 10 and Figure 11 In one embodiment, the blowing compensation unit 420 further includes a piece support plate 424. The piece support plate 424 is higher than the blowing plate 422. When the blowing compensation unit 420 is in the blowing state, the first piece 20 and the second piece 30 are supported by the piece support plate 424 and are not attached to the blowing plate 422. This prevents the first piece 20 and the second piece 30 from affecting the blowing effect of the blowing plate 422. In other words, in a direction perpendicular to the plane in which the first piece 20 and the second piece 30 lie, the piece support plate 424 is closer to the first piece 20 and the second piece 30 than the blowing plate 422.

[0183] It is understandable that if Figure 3As shown, the first cut piece 20 and the second cut piece 30 are arranged in parallel, and the blowing compensation part 420 is located below the first cut piece 20. Therefore, in the direction perpendicular to the plane where the first cut piece 20 and the second cut piece 30 are located, the cut piece support plate 424 is closer to the first cut piece 20 and the second cut piece 30 than the blowing plate 422. The cut piece support plate 424 is higher than the blowing plate 422, and plays a supporting role for the first cut piece 20 and the second cut piece 30.

[0184] Furthermore, the cutting piece support plate 424 is connected to the second telescopic mechanism 421 .

[0185] It is understood that the cutting plate 424 can be fixedly connected to the second telescopic mechanism 421, that is, the cutting plate 424 can be relatively stationary and not move relative to the second telescopic mechanism 421, and the connection method can be gluing, welding, threading, snap connection, etc. Similarly, the cutting plate 424 can also be slidably connected to the second telescopic mechanism 421, so that the cutting plate 424 can be adjusted according to the position of the cutting plate to accommodate cutting plates of different widths.

[0186] In this embodiment, the cutting piece support plate 424 is slidably connected to the second telescopic mechanism 421. Figure 10 As shown, the cutting piece support plate 424 is connected to the end of the second telescopic mechanism 421 connected to the automatic sewing machine 10. The cutting piece support plate 424 can be slid to the side of the second telescopic mechanism 421 near the air outlet and fixed. When not manually adjusted, the cutting piece support plate 424 does not move relative to the automatic sewing machine 10. At this time, regardless of whether the blowing compensation unit 420 is in the blowing state, the cutting piece support plate 424 can support the first cutting piece 20 and the second cutting piece 30.

[0187] See also Figure 10 Furthermore, a smooth panel support 424 is located on one side of the air outlet plate in the direction of the air flow from the air outlet plate. It is understood that the air flow from the air outlet plate is directed toward the air outlet portion, parallel to the plane where the first and second panels 20, 30 lie, and perpendicular to the direction of travel of the first and second panels 20, 30. The panel support 424 is located on one side of the air outlet plate to support the first and second panels 20, 30 when the air outlet plate blows air, preventing the panels from sticking to the air outlet plate and affecting the air flow.

[0188] It can be understood that the cutting piece support plate 424 is used to support the first cutting piece 20 and the second cutting piece 30, and needs to be in contact with the first cutting piece 20 or the second cutting piece 30. Its smooth surface can prevent the first cutting piece 20 or the second cutting piece 30 from being hooked, thereby protecting the first cutting piece 20 and the second cutting piece 30.

[0189] See also Figure 13 and Figure 14In a specific setting, the transmission device 300 includes: a mobile platform 310, which is movably connected to the mounting frame 700; a mobile tensioning wheel portion 320, which is connected to the mobile platform 310, and the mobile tensioning wheel portion 320 includes a first driving member 321 and a first tensioning wheel 322, the first driving member 321 is used to drive the first tensioning wheel 322 to rotate, and the first driving member 321 is built into the first tensioning wheel 322.

[0190] The movable tensioning wheel unit 320 includes a first driving member 321 and a first tensioning wheel 322. The first driving member 321 is used to drive the first tensioning wheel 322 to rotate. The first driving member 321 is internal to the first tensioning wheel 322. During the automatic sewing process, the first and second panels 20 and 30 are wound between the two tensioning wheels, and the rotation of the tensioning wheels drives the first and second panels 20 and 30 to rotate.

[0191] In the above scheme, the first driving member 321 is built into the first tensioning wheel 322. Compared with the prior art in which the driving member is connected to the outside of the tensioning wheel, the volume of the movable tensioning wheel part 320 is smaller, and the movable tensioning wheel part 320 is coordinated with the movable platform 310, so that the movable tensioning wheel part 320 can move relative to the other tensioning wheel on the mounting frame 700. Since the volume of the movable tensioning wheel part 320 is small, when approaching the other tensioning wheel, the problem of the two tensioning wheels being unable to approach each other due to the large volume of the driving member in the prior art will not occur. As a result, the two tensioning wheels can be moved to a closer position relative to the tensioning wheels in the prior art, and are thus suitable for small-sized clothing to meet the use requirements of clothing of various sizes.

[0192] It is understood that the mobile platform 310 is movably connected to the mounting frame 700 so that the mobile platform 310 can move relative to the mounting frame 700, which can be achieved by using a transmission mechanism, such as a gear rack mechanism. Figure 13 and Figure 15 As shown, in this embodiment, a slide rail 340 is provided between the mobile platform 310 and the mounting frame 700 , and the mobile platform 310 is slidably connected to the slide rail 340 .

[0193] It can be understood that the mobile platform 310 and the mounting frame 700 are connected by sliding, wherein the slide rail 340 is fixedly connected to the mounting frame 700, and the mobile platform 310 can be provided with pulleys etc. adapted to the slide rail 340 to enable the mobile platform 310 to slide relative to the mounting frame 700 along the slide rail 340.

[0194] See also Figure 15Furthermore, the movable platform 310 includes a support plate 311 and a third driving member 312 . The third driving member 312 is used to drive the support plate 311 to slide along the slide rail 340 , and the movable tensioning wheel portion 320 is connected to the support plate 311 .

[0195] It is understood that since the movable tensioning wheel portion 320 is connected to the support plate 311, the third driving member 312 drives the support plate 311 to slide along the slide rail 340, and the support plate 311 drives the movable tensioning wheel portion 320 to move, thereby achieving movement of the movable tensioning wheel portion 320. The support plate 311 can be provided with a pulley or the like that is compatible with the slide rail 340, so that the support plate 311 can slide along the slide rail 340 under the drive of the third driving member 312.

[0196] It should be noted that the third driving member 312 can be a power source such as a motor, a heat engine, etc. In this embodiment, the third driving member 312 is a motor.

[0197] See also Figure 13 In a specific setting, the transmission device 300 also includes a movable tensioning wheel portion 320 and a fixed tensioning wheel portion 330. The fixed tensioning wheel portion 330 is fixedly connected to the mounting frame 700. The fixed tensioning wheel portion 330 includes a second driving member 331 and a second tensioning wheel 332. The second driving member 331 is used to drive the second tensioning wheel 332 to rotate.

[0198] It can be understood that the fixed connection between the fixed tensioning wheel part 330 and the mounting frame 700 means that during the sewing process, the relative positions of the fixed tensioning wheel part 330 and the mounting frame 700 are not adjusted, and the connection method between the fixed tensioning wheel part 330 and the mounting frame 700 can adopt one of the fixed connection or detachable connection, such as threaded connection, welding, etc.

[0199] It can be understood that in order to tension and transmit the cut pieces by the movable tensioning wheel portion 320 and the fixed tensioning wheel portion 330, the movable tensioning wheel portion 320 and the fixed tensioning wheel portion 330 should be respectively arranged on both sides of the sewing device 500, and the external dimensions of the second tensioning wheel 332 and the first tensioning wheel 322 are comparable, so that the first cut piece 20 and the second cut piece 30 can be wound around the first tensioning wheel 322 and the second tensioning wheel 332 and can be driven by the rotation of the first tensioning wheel 322 and the second tensioning wheel 332.

[0200] It should be noted that the second driving member 331 can be a power source such as a motor, a heat engine, etc., as long as it can drive the second tensioning wheel 332 to rotate. In this embodiment, the second driving member 331 is a motor.

[0201] It should be noted that the second driving member 331 can be externally connected to the second tensioning wheel 332 or built into the second tensioning wheel 332. When the second driving member 331 is built into the second tensioning wheel 332, the structure of the second tensioning wheel 332 is consistent with that of the first tensioning wheel 322.

[0202] In this embodiment, the second driving member 331 is located on one side of the second tensioning wheel 332, and the second driving member 331 is connected to the mounting frame 700, and the second tensioning wheel 332 is connected to the output shaft of the second driving member 331, so that the second tensioning wheel 332 and the output shaft of the second driving member 331 rotate synchronously.

[0203] It is understood that when the second driving member 331 is located on one side of the second tensioning wheel 332, one end of the second tensioning wheel 332 is connected to the output shaft of the second driving member 331, and the other end is used to tension and transmit the cut piece. The second tensioning wheel 332 can be a one-piece structure or can be composed of multiple connected parts.

[0204] See also Figure 13 and Figure 14 In a specific setting, the first tensioning wheel 322 includes a sleeve 3221, a long tube 3222 and a roller 630 kit. The sleeve 3221 is connected to the output shaft of the first driving member 321 and is sleeved on the outside of the first driving member 321. It can rotate synchronously with the output shaft of the first driving member 321. The long tube 3222 is connected between the sleeve 3221 and the roller 630 kit, so that the roller 630 kit rotates synchronously with the sleeve 3221.

[0205] like Figure 14 As shown, the sleeve 3221 has a stepped cylindrical structure, with its larger end sleeved on the outside of the first driving member 321 and the other end connected to the output shaft of the first driving member 321, so that the sleeve 3221 and the output shaft of the first driving member 321 rotate synchronously.

[0206] It is understood that the long tube 3222 connects between the sleeve 3221 and the roller assembly 3223, acting as a power transmission mechanism, enabling the roller assembly 3223 to rotate synchronously with the sleeve 3221. The long tube 3222 is internally mounted within the roller assembly 3223. When the first tensioning wheel 322 tensions the cut piece and drives it to rotate, the sleeve 3221 and the roller assembly 3223 come into contact with the cut piece. To ensure smooth transmission of the cut piece and avoid wrinkles caused by uneven height during transmission, the sleeve 3221 and the roller assembly 3223 are of the same size.

[0207] See also Figure 14 and Figure 15Furthermore, the movable tensioning wheel unit 320 further includes a support member 323, which is connected between the first driving member 321 and the movable platform 310. The function of the support member 323 is to connect the movable platform 310 and the movable tensioning wheel unit 320 and to fix the relative position of the first driving member 321 and the movable platform 310, so that the first driving member 321 can move with the movement of the movable platform 310.

[0208] See also Figure 14 In one embodiment, the supporting component 323 includes: a vertical plate 3231, which is perpendicular to the movable platform 310; a horizontal plate 3232, which is horizontal to the movable platform 310, and one end of the horizontal plate 3232 is fixedly connected to the vertical plate 3231; a connecting plate 3233, which is parallel to the vertical plate 3231, and one end of the connecting plate 3233 is connected to the other end of the horizontal plate 3232, and the other end of the connecting plate 3233 is fixedly connected to the first driving member 321.

[0209] like Figure 14 As shown, the connecting plate 3233 is parallel to the vertical plate 3231 and faces the upper and lower sides of the horizontal plate 3232 respectively. The connecting plate 3233 and the vertical plate 3231 are respectively connected to the moving platform 310 and the first driving member 321.

[0210] It should be noted that the vertical plate 3231 and the movable platform 310, the horizontal plate 3232 and the vertical plate 3231, the horizontal plate 3232 and the connecting plate 3233, and the connecting plate 3233 and the first driving member 321 are all detachably connected. In this embodiment, threaded connections are used.

[0211] Furthermore, a plurality of reinforcing plates are provided between the vertical plate 3231 and the movable platform 310 and between the connecting plate 3233 and the transverse plate 3232 , wherein the function of the reinforcing plates is to make the vertical plate 3231 and the connecting plate 3233 more stable.

[0212] In one embodiment, the first tensioning wheel 322 further includes a spherical tail seat 3224 . One end of the spherical tail seat 3224 is a hemispherical structure, and the other end of the spherical tail seat 3224 is sleeved on an end of the connecting plate 3233 near the first driving member 321 .

[0213] It can be understood that when the first tensioning wheel 322 tensions the piece and drives the piece to rotate by rotating itself, when the width of the piece is wider, the piece may contact areas outside the sleeve 3221, the long tube 3222 and the roller kit 3223. In order to protect the piece from being hooked when it contacts other areas, a spherical tail seat 3224 is provided to extend the first tensioning wheel 322 so that the first tensioning wheel 322 can be adapted to wider pieces, and the semicircular structure at one end of the spherical tail seat 3224 is used to allow the wider piece to hang naturally and prevent the piece from being hooked by other components.

[0214] like Figure 14 As shown, it can be understood that the function of the spherical tailstock 3224 is to protect the cut piece from being hooked by other devices. One end of the spherical tailstock 3224 is hemispherical, and the other end is cylindrical and has a groove that matches the connecting plate 3233. The groove is mounted on the outside of the connecting plate 3233 and is fixedly connected to the connecting plate 3233. To ensure smooth transmission of the cut piece, the radius of the spherical tailstock 3224 that contacts the cut piece should be consistent with the radius of the sleeve 3221.

[0215] When the first tensioning wheel 322 tensions the cut piece and rotates the cut piece, the sleeve 3221, roller assembly 3223, and spherical tailstock 3224 of the first tensioning wheel 322 come into contact with the cut piece. Since the spherical tailstock 3224 is connected to the connecting plate 3233, and both the sleeve 3221 and roller assembly 3223 can rotate and drive the cut piece under the drive of the first driving member 321, in order to ensure more uniform force on the cut piece during rotation and reduce friction between the stationary spherical tailstock 3224 and the moving cut piece, the contact area between the sleeve 3221 and roller assembly 3223 and the cut piece should be maximized, while the contact area between the spherical tailstock 3224 and the cut piece should be reduced. Therefore, in this embodiment, one cylindrical end of the spherical tailstock 3224 can be sleeved inside the sleeve 3221, leaving only the hemispherical end of the spherical tailstock 3224 outside the sleeve to protect the cut piece.

[0216] It should be noted that the spherical tail seat 3224 is connected to the connecting plate 3233, and the sleeve 3221 rotates with the first driving member 321. In order for the spherical tail seat 3224 to not interfere with the rotation of the sleeve 3221, the spherical tail seat 3224 and the sleeve 3221 are close to but not in contact with each other, and there is a small gap between them.

[0217] like Figure 14 As shown, further, a protective cover 3234 is provided on a side of the transverse plate 3232 far from the first driving member 321 , and the edge of the protective cover 3234 is smooth.

[0218] It is understood that when the first tensioning wheel 322 tensions the cut piece and drives the cut piece to rotate by its own rotation, if the sewing device 500 is located close to the first tensioning wheel 322 and the sewing position 500 is lower than the highest position of the first tensioning wheel 322, the cut piece may contact the side of the transverse plate 3232 away from the first driving member 321 during the downward pressure stitching of the sewing device 500. To prevent the cut piece from contacting the transverse plate 3232 and causing the transverse plate 3232 to hook onto the cut piece, a protective cover 3234 is provided on the outer surface of the transverse plate 3232. The edges of the protective cover 3234 that may contact the cut piece are rounded to protect the cut piece.
