Description

Technical Field

[0001] The invention relates to the technical field of forming devices, in particular to a single-piece ribbing machine. Background Art

[0002] Traditionally, cuffs are made by manual sewing. Since the cuff production process requires multiple operation steps such as folding and curling, the above steps need to be manually operated during manual production, and then the folded and curled cuff fabric is sewn together by a sewing machine. The production efficiency is extremely low. In response to this, semi-automatic or automatic cuff ribbing machines have appeared on the market. Most of the equipment on the market can only fold and sew the edges once, which cannot meet the preparation needs of multiple folds and needs to be improved. Summary of the invention

[0003] To solve at least one of the above technical defects, the present invention provides the following technical solutions:

[0004] The present application discloses a single-piece rib machine, comprising a frame, a feeding mechanism, a folding and feeding mechanism, a first material transfer mechanism, a first sewing mechanism, and also comprising a secondary folding mechanism, a second material transfer mechanism, a second sewing mechanism, a second material clamping and conveying assembly, an outward turning mechanism, a stretching mechanism, and a feeding mechanism. The frame is provided with a material conveying path, and the feeding mechanism, the folding and feeding mechanism, the first material transfer mechanism, the first sewing mechanism, the secondary folding mechanism, the second material transfer mechanism, the second sewing mechanism, and the second material clamping and conveying assembly are sequentially arranged on the frame along the material conveying path; the feeding mechanism is used to feed material to the conveying path;

[0005] The folding and feeding mechanism is used to fold the cloth transferred by the feeding mechanism and convey it to the first place of the material transfer mechanism, and the material transfer mechanism conveys the folded cloth to the first and second folding mechanisms of the sewing mechanism in sequence, and the sewing mechanism sews the edges of the folded cloth;

[0006] The secondary folding mechanism is used to fold the fabric after sewing, and the second material transfer mechanism sequentially conveys the secondary folded fabric to the second sewing mechanism and the second material clamping and conveying assembly, and the second sewing mechanism sews the edges;

[0007] The second material clamping and conveying assembly includes a shift assembly, a rotating shaft 1, a pressing mechanism 2, and an opening mechanism, wherein the opening mechanism is used to open the cloth port, the shift assembly is used to insert the two rotating shafts 1 into the opened port and tighten them, and the shift assembly is used to transfer the tightened cloth to the eversion mechanism;

[0008] The stretching mechanism is arranged opposite to the eversion mechanism. The eversion mechanism is used to evert the cloth supported by the two rotating shafts. The stretching mechanism stretches and relaxes the everted cloth by opening and closing. The unloading mechanism is used to unload the cloth processed by the stretching mechanism.

[0009] In this solution, the process flow is redesigned, and the execution actions of each process are correspondingly set, enabling two-fold folding, hemming, and blanking of the fabric, improving the degree of automation. For fabrics such as robb, a stretching mechanism is specifically set to make the ribbing manifest through the opening and closing actions.

[0010] Furthermore, the secondary folding mechanism includes a pressing mechanism I, a displacement mechanism VI, a telescopic mechanism IX, a telescopic mechanism X, a telescopic mechanism XI, a bracket V, a bracket VI, and a pressing plate III. The displacement mechanism VI is arranged on the frame, and a bracket V is arranged at the mobile end of the displacement mechanism VI. The telescopic mechanism IX is arranged on the bracket V, and a bracket VI is arranged at the mobile end of the telescopic mechanism IX. The telescopic mechanism X and the telescopic mechanism XI are arranged on the bracket VI. A clamping plate III is arranged at the mobile end of the telescopic mechanism X, and a clamping plate IV is arranged on the bracket VI below the clamping plate III. The telescopic mechanism X reciprocates longitudinally above the clamping plate IV to make the clamping plate III and the clamping plate IV cooperate to clamp or release the fabric located in the middle. A pressing plate III is arranged at the telescopic end of the telescopic mechanism XI. With the cooperation of the displacement mechanism VI, the telescopic mechanism IX, and the telescopic mechanism X, the clamping plate III and the clamping plate IV clamp the end of the fabric transferred by the material transfer mechanism I. A pressing mechanism I is arranged on the side of the conveying channel at the end of the stroke of the material transfer mechanism I. When the clamping plate III and the clamping plate IV clamp the fabric, the other end on the conveying channel is pressed by the pressing mechanism I. The displacement mechanism VI moves along the transfer direction of the transfer mechanism I to move the clamped end of the fabric forward to complete the folding. The telescopic mechanism XI reciprocates longitudinally to press or release the side of the fabric at the hemming position with the pressing plate III.

[0011] During the transfer process of the material transfer mechanism I, clamping the end of the fabric with the clamping plate helps improve stability. Being pressed by the pressing mechanism helps improve the stability of the folding process. The cooperation between the telescopic mechanism XI and the pressing plate III helps make the side flat, facilitating subsequent sewing.

[0012] Furthermore, pressing mechanisms I are respectively arranged at the opposite side positions of the conveying channel. The two groups of pressing mechanisms help improve the stability of the folding process.

[0013] Furthermore, the pressing mechanism I includes a telescopic mechanism XII, a telescopic mechanism XIII, and a pressing plate IV. The telescopic mechanism XIII is arranged at the mobile end of the telescopic mechanism XII, and the pressing plate IV is arranged at the mobile end of the telescopic mechanism XIII. With the cooperation of the telescopic mechanism XII and the telescopic mechanism XIII, the pressing plate IV presses or releases the fabric on the conveying channel.

[0014] Furthermore, the transfer directions of the material transfer mechanism I, the material transfer mechanism II, and the displacement mechanism VI are the same.

[0015] Further, the second material clamping and conveying assembly includes a shift assembly, a rotating shaft 1, a pressing mechanism 2, an opening mechanism, and a driving motor. The shift assembly includes a shift mechanism 7, a shift mechanism 8, a shift mechanism 9, and a bracket 7. The shift mechanism 7 is arranged on the frame and the bracket 7 is arranged at the moving end of the shift mechanism 7. The shift mechanism 8 is arranged on the bracket 7. The bracket 8 is arranged at the moving end of the shift mechanism 8. The shift mechanism 9 is arranged on the bracket 8 and the driving motor is arranged in parallel at the moving end of the shift mechanism 9. The rotating shaft 1 is arranged at the output end of the driving motor. The shift mechanism 9 moves the driving motors toward or away from each other to make the two rotating shafts 1 open and close, and the pressing mechanism 2 presses the side of the material transfer mechanism 2 to press the side of the material transfer mechanism 2, and the opening mechanism opens the port of the cloth. Under the drive of the shift mechanism 8, the two rotating shafts 1 are extended into the opening port, and the shift mechanism 9 is used to move the two rotating shafts 1 away from or towards each other to tighten or loosen the cloth, and the shift mechanism 7 is used to move the cloth to the outside-turning mechanism in the tightened state.

[0016] The pressing action of the second pressing mechanism facilitates the opening mechanism to force the cloth port to open, and the driving motor drives the rotating shaft to rotate to facilitate entry into the cloth port. The shifting assembly composed of multiple shifting mechanisms facilitates the shifting of each action mechanism according to needs to achieve the completion of the predetermined execution action.

[0017] Furthermore, the shifting mechanism nine is a belt slide module and driving motors are respectively arranged on the parallel belt bodies, which facilitates displacement toward or away from each other and has low cost.

[0018] Furthermore, the opening mechanism includes a telescopic mechanism sixteen and a suction cup mechanism two. The suction cup mechanism two is arranged at the telescopic end of the telescopic mechanism sixteen and reciprocates in the longitudinal direction. The longitudinal telescopic movement facilitates adsorption of the top surface and promotes the opening of the corresponding port.

[0019] Furthermore, the pressing mechanism 2 includes a telescopic mechanism 14 and a pressing plate 5. The telescopic mechanism 14 is arranged on the frame and the pressing plate 5 is arranged at its moving end. The telescopic mechanism 14 reciprocates the pressing plate 5 in the longitudinal direction to press or separate the cloth on the conveying path.

[0020] Furthermore, the shifting mechanism eight has the same transfer direction as the material shifting mechanism two, and the transfer direction of the shifting mechanism seven is perpendicular to the transfer direction of the shifting mechanism eight, and the predetermined direction facilitates layout.

[0021] Furthermore, the feed channel is L-shaped and the middle section and the first section thereof are both straight-line-shaped. The first section of the feed channel is provided with a loading mechanism and a folding and feeding mechanism. The middle section of the feed channel is provided with a first material transfer mechanism, a first sewing mechanism, a secondary folding mechanism, and a second material transfer mechanism. The first section of the feed channel is provided with a second material clamping and conveying assembly, an external turning mechanism, a stretching mechanism, and a material unloading mechanism at a position of the frame relative to the first section of the feed channel. This facilitates the layout of each action mechanism.

[0022] Further, the stretching mechanism includes a second support rod, a fourteenth displacement mechanism, a fifteenth displacement mechanism, a sixteenth displacement mechanism, and an eleventh bracket. An installation seat is provided at the moving end of the fourteenth displacement mechanism, and the installation seat is reciprocally displaced longitudinally. The fifteenth displacement mechanism is provided on the installation seat, and the eleventh bracket is provided at the moving end of the fifteenth displacement mechanism. The sixteenth displacement mechanism is provided on the eleventh bracket, and the second support rod is arranged in parallel at the moving end of the sixteenth displacement mechanism. With the cooperation of the fourteenth displacement mechanism and the fifteenth displacement mechanism, the second support rod is inserted into or disengaged from the port of the cloth after eversion. When inserting into the cloth port, the second support rod is moved towards or away from each other by the sixteenth displacement mechanism to tighten or loosen the cloth. The opening and closing action of the second support rod to tighten or loosen the cloth helps to manifest the ribbing on the cloth and improve the aesthetics.

[0023] Further, the eversion mechanism includes a tenth displacement mechanism, an eleventh displacement mechanism, a twelfth displacement mechanism, a thirteenth displacement mechanism, a ninth bracket, a tenth bracket, a first support rod, and a jaw mechanism. The tenth displacement mechanism and the twelfth displacement mechanism are provided on the frame. The ninth bracket is provided at the moving end of the tenth displacement mechanism. The eleventh displacement mechanism is provided on the ninth bracket, and the jaw mechanism is oppositely arranged at its moving end. The jaw mechanism is moved towards or away from each other by the eleventh displacement mechanism. The tenth bracket is provided at the moving end of the twelfth displacement mechanism, and the thirteenth displacement mechanism is provided on the tenth bracket. The first support rod is arranged in parallel at the moving end of the thirteenth displacement mechanism, and the first support rod is moved towards or away from each other by the thirteenth displacement mechanism. The two first support rods are located between the two jaw mechanisms. When the seventh displacement mechanism moves the cloth to a predetermined position, the jaw mechanism is moved to clamp the side of the cloth by the cooperation of the tenth displacement mechanism and the eleventh displacement mechanism, and the cloth is everted onto the first support rod by abutting against the cloth with the first support rod during the reset process of the tenth displacement mechanism. The eversion action of the eversion mechanism causes the inner wall to turn into the outer wall, which helps to hide the seam edge and improve the aesthetics.

[0024] Further, the blanking mechanism includes a conveying component, a pushing component, and a first baffle. The conveying component passes between the stretching mechanism and the eversion mechanism. The first baffle is provided on the side frame of the conveying component and is higher than the conveying component. With the cooperation of the fourteenth displacement mechanism and the fifteenth displacement mechanism in the stretching mechanism, the first baffle is located between the two second support rods in the stretching mechanism. During the reset process of the second support rod, the cloth on the second support rod is separated and falls onto the conveying component under the limitation of the first baffle. The pushing component is arranged in front of or behind the first baffle along the conveying direction to push the cloth conveyed by the conveying component down. Under the action of the first baffle, the cloth on the second support rod is separated and falls onto the conveying component, and then is conveyed to the next process. For example, the pushing component pushes it out of the conveying component, which improves the degree of automation.

[0025] Further, both the first material transfer mechanism and the second material transfer mechanism include a fifth displacement mechanism, a sixth telescopic mechanism, a seventh telescopic mechanism, a fourth support, and a first pressing plate. The fifth displacement mechanism is arranged on the frame, and the fourth support is arranged at the moving end of the fifth displacement mechanism. The sixth telescopic mechanism is arranged on the fourth support. The seventh telescopic mechanism is arranged at the telescopic end of the sixth telescopic mechanism, and the first pressing plate is arranged at the telescopic end of the seventh telescopic mechanism. The sixth telescopic mechanism and the seventh telescopic mechanism cooperate to drive the first pressing plate to press or disengage from the fabric on the feeding channel.

[0026] Further, the conveying assembly is of the conveyor belt type.

[0027] Further, the pushing component includes a fifteenth telescopic mechanism and a pushing plate. The pushing plate is arranged at the telescopic end of the fifteenth telescopic mechanism. A storage tank is arranged on the corresponding frame on the other side of the conveying assembly along the telescopic direction of the fifteenth telescopic mechanism. Adding the storage tank can pre-store the pushed fabrics, etc., which is convenient for subsequent centralized transfer and processing.

[0028] Further, the first material transfer mechanism further includes a first edge pressing mechanism. The first edge pressing mechanism includes an eighth telescopic mechanism, a pivot shaft, and a second pressing plate. The eighth telescopic mechanism is pivotally connected to the fourth support, and its telescopic end is pivotally connected to a fixed block. The fixed block is pivotally connected to the pivot shaft, and the end of the pivot shaft is pivotally connected to the fourth support. The second pressing plate is arranged on the pivot shaft, and the second pressing plate is at the end of the first pressing plate. Adding the first edge pressing mechanism helps to keep the fabric flat during the movement process, which is convenient for subsequent process processing.

[0029] Further, the folding and feeding mechanism includes a fourth displacement mechanism, a second support, a third support, a second telescopic mechanism, a third telescopic mechanism, a fourth telescopic mechanism, and a fifth telescopic mechanism. The second support is arranged at the moving end of the fourth displacement mechanism, and the second support is moved along the feeding channel. The second telescopic mechanism is arranged on the second support, and the third support is arranged at the moving end of the second telescopic mechanism. The first clamping plate, the third telescopic mechanism, and the fourth telescopic mechanism are arranged on the third support. A convex end is arranged at the end of the first clamping plate, and a notch for the convex end to pass through longitudinally is arranged at the starting end of the feeding channel. The fifth telescopic mechanism is arranged at the moving end of the third telescopic mechanism, and a pushing block is arranged at the moving end of the fifth telescopic mechanism. The second clamping plate is arranged at the telescopic end of the fourth telescopic mechanism. Under the combined displacement of the fourth displacement mechanism and the second telescopic mechanism, the convex end passes through the notch from the bottom upwards, and the third telescopic mechanism moves the second clamping plate reciprocally along the longitudinal direction above the first clamping plate, so that the first clamping plate and the second clamping plate cooperate to clamp or release the fabric located in the middle. The pushing block is moved reciprocally along the longitudinal direction in front of the first clamping plate by the second telescopic mechanism, and when the first clamping plate and the second clamping plate are in the clamping state, the pushing block located below the first clamping plate moves towards the rear of the first clamping plate by the fifth telescopic mechanism. The folded fabric end is advanced by moving the fourth displacement mechanism along the length extension direction of the conveying channel where it is located. After the pushing block is reset, the second telescopic mechanism drives the first clamping plate to press the fabric on the feeding channel, and the fabric is displaced to the first material transfer mechanism by the fourth displacement mechanism.

[0030] In this solution, the folding and feeding mechanism is improved. After the clamping end of the clamping plate, a push block is used to push backward under the clamping plate, which helps to improve the flatness of the end of the clamped fabric and facilitates the operation of subsequent processes.

[0031] Furthermore, the feeding mechanism includes a material lifting component, a first clamping and conveying component, and a side baffle mechanism; the material lifting component includes a storage platform and a displacement mechanism I. The displacement mechanism I is arranged on the frame, and the storage platform is arranged at the moving end of the displacement mechanism I; the first clamping and conveying component includes a displacement mechanism II, a bracket I, a telescopic mechanism I, and a suction cup mechanism I. The displacement mechanism II is arranged on the frame, and the bracket I is arranged at the moving end of the displacement mechanism II. The telescopic mechanism I is arranged on the bracket I, and the suction cup mechanism I is arranged at the moving position of the telescopic mechanism I. The telescopic mechanism I reciprocates the suction cup mechanism I longitudinally. Under the movement of the displacement mechanism II and the telescopic mechanism I, the suction cup mechanism I adsorbs the fabric piece on the storage platform and transfers it to the feeding channel; the side baffle mechanism includes a displacement mechanism III and side baffles. The two side baffles are arranged oppositely, and the displacement mechanism III moves the side baffles towards and away from each other. The first clamping and conveying component moves the fabric piece between the two side baffles. During the process of the two side baffles moving towards each other, the fabric piece in the middle is adjusted in position. Air holes are arranged on the feeding channel between the two side baffles.

[0032] Adding air holes can be connected to equipment such as air suction and air extraction. For example, when the first clamping and conveying component feeds the fabric onto the feeding channel, air can be discharged through the air holes to reduce friction, which helps to improve the flatness of the fabric. For example, during the folding process of the folding mechanism, air suction through the air holes helps to improve the stability of the fabric. The side baffle mechanism helps to adjust the position of the fabric through the relative movement of the side baffles, facilitating the execution of subsequent folding actions.

[0033] Furthermore, it also includes a mounting frame. The mounting frame is provided with a displacement mechanism IV and a displacement mechanism II. The displacement mechanism IV includes a synchronous belt I, a driving wheel I, a driving shaft I, and a driving motor I. The displacement mechanism II includes a synchronous belt II, a driving wheel II, a driving shaft II, and a driving motor II. The driving shafts I and II are respectively arranged at both ends of the mounting frame, and the driving shafts I and II are correspondingly connected to the output ends of the driving motors I and II. Driving wheels I and II are arranged at both ends of the driving shafts I and II, and the driving wheels I and II on the driving shafts I and II are correspondingly connected by the synchronous belt I and the synchronous belt II. The driving wheel I on the driving shaft I is fixedly connected and the driving wheel II is rotatably connected. The driving wheel II on the driving shaft II is fixedly connected and the driving wheel I is rotatably connected. The synchronous belt I and the synchronous belt II are respectively connected to the bracket I and the bracket II. Using the mounting frame as a carrier helps to improve the assembly speed.

[0034] Further, it further includes a control end, and the control end is connected to the feeding mechanism, the folding and feeding mechanism, the first material transfer mechanism, the first sewing mechanism, the secondary folding mechanism, the second material transfer mechanism, the second sewing mechanism, the second clamping and conveying assembly, the outer turning mechanism, the stretching mechanism, and the discharging mechanism.

[0035] Further, the folding and feeding mechanism folds and conveys the material in its transfer direction to the first material transfer mechanism, and sews the edge along the transfer direction of the first material transfer mechanism by the first sewing mechanism; the secondary folding mechanism folds the fabric along the transfer direction of the first transfer mechanism, and the second sewing mechanism performs secondary edge sewing at the edge sewn by the first sewing mechanism; the opening mechanism opens the port of the fabric after the first folding, the shifting assembly inserts the two first rotating shafts into the opened port and tightens it, and the shifting assembly transfers the tightened fabric to the outer turning mechanism. Under the limitation of the edge sewing position, folding direction, etc., it is convenient to perform two - time folding, edge sewing and outer turning of a single - piece rib.

[0036] Further, the feeding mechanism includes a replenishing mechanism. The replenishing mechanism is located above the material lifting assembly. The replenishing mechanism includes the seventeenth shifting mechanism, a carrier plate, and a second baffle. A carrier plate is arranged at the moving end of the seventeenth shifting mechanism, and the carrier plate is slidably connected to the frame. A second baffle is longitudinally arranged above the moving path of the carrier plate. When the seventeenth shifting mechanism drives the carrier plate to move away from the position point above the storage platform, the second baffle pushes the material on the carrier plate onto the storage platform.

[0077] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0078] Embodiment 1

[0079] As Figures 1 - 4 shown, the present single-thread rib machine includes a frame. A material conveying channel 14 is formed on the frame 1. A feeding mechanism 2, a folding and feeding mechanism 3, a material shifting mechanism I 4, a sewing mechanism I, a secondary folding mechanism 6, a material shifting mechanism II 8, a sewing mechanism II, and a second clamping and conveying assembly 9 are sequentially arranged on the frame along the material conveying channel 14. The cloth is transferred to the outward turning mechanism 10 by the second clamping and conveying assembly 9, the cloth after outward turning is processed by the stretching mechanism 11, and the stretched cloth is discharged by the discharging mechanism 12.

[0080] In this example, the material conveying channel 14 is L-shaped, and its middle section and the first section are both linearly extended. At the first section of the material conveying channel 14, a feeding mechanism 2 and a folding and feeding mechanism 3 are installed on the frame 1. On the middle section frame of the material conveying channel 14, a material transfer mechanism I 4, a sewing mechanism I, a secondary folding mechanism 6, and a material transfer mechanism II are installed. On the frame opposite to the first section of the material conveying channel, a second clamping and conveying component 9, an outer turning mechanism 10, an extension mechanism 11, and a blanking mechanism 12 are installed. The sewing mechanism I and the sewing mechanism II are not shown in the attached drawings. The sewing mechanism I is installed at the installation position A5, and the sewing mechanism II is installed at the installation position B7. For the sewing mechanism I and the sewing mechanism II, they can be directly purchased on the market and are used for sewing the edges, which will not be elaborated here.

[0081] In this example, as Figure 3 , Figure 5 shown, a feeding mechanism 2 is installed at the end of the first section of the material conveying channel to feed the conveying channel. The feeding mechanism 2 includes a material lifting component 20, a first clamping and conveying component 21, and a side baffle mechanism 23.

[0082] The material lifting component includes a storage platform 201 and a displacement mechanism I 202. The displacement mechanism I is longitudinally installed on the frame outside the first section of the material conveying channel, such as a lead screw type. The moving end of the displacement mechanism I is horizontally fixed with the storage platform, and stacked block-shaped fabrics can be pre-placed on the storage platform. In addition, a replenishing mechanism can also be provided, such as Figure 23 shown. The replenishing mechanism 24 is located above the material lifting component 20. The replenishing mechanism includes a displacement mechanism XVII 242, a carrier plate 241, and a second baffle 243. The displacement mechanism XVII uses a cylinder. The displacement mechanism XVII is fixed on the frame at a position above the first section of the material conveying channel and the first clamping and conveying component 21 and along the extension direction of the first section. The moving end of the displacement mechanism XVII is fixed with the carrier plate. The carrier plate is slidably connected to the frame through a slide rail, a slider, etc. A second baffle is longitudinally fixed above the moving path of the carrier plate. Both side edges of the second baffle are fixed to the frame. Driven by the displacement mechanism XVII, the initial position point of the carrier plate is directly above the storage platform. Fabrics can be pre-stacked on the carrier plate. The second baffle is behind the initial position point of the carrier plate. When the storage platform is lifted to a predetermined position, driven by the displacement mechanism XVII, the carrier plate moves away from the initial position point above the storage platform. During the movement, the materials on the carrier plate are pushed onto the storage platform by the second baffle.

[0083] As Figures 1 - 4 , Figure 8As shown, in this example, the first material clamping and conveying assembly 21 includes a second shifting mechanism 210, a first support 211, a first telescopic mechanism 212, and a first suction cup mechanism 213. The second shifting mechanism is installed in the frame cavity below the material conveying channel. A gantry-type first support 211 is installed at the moving end of the second shifting mechanism to move the first support along the extension direction of the conveying channel where the second shifting mechanism is located. The first telescopic mechanism 212, such as a cylinder, is installed longitudinally on the first support 211. The first suction cup mechanism 213 is horizontally installed at the moving end of the first telescopic mechanism, such as formed by fixing suction nozzles on a mounting plate. The suction nozzles are connected to a vacuum pumping mechanism inside or outside the frame. The first telescopic mechanism reciprocates longitudinally to move the first suction cup mechanism. During use, the second shifting mechanism moves the first support so that the first suction cup mechanism at the moving end of the first telescopic mechanism is above the storage platform. The first telescopic mechanism moves downward to adsorb the ribbed fabric with the first suction cup mechanism. The first telescopic mechanism resets the first suction cup mechanism. Then, the second shifting mechanism moves the first support so that the first suction cup mechanism is above the conveying channel. Then, the first telescopic mechanism moves the first suction cup mechanism downward to place the fabric on the material conveying channel.

[0084] As Figures 1 - 4 , Figure 6 , Figure 7 As shown, the edge blocking mechanism 23 includes a third shifting mechanism 231 and edge blockers 232. The two edge blockers are oppositely arranged on the material conveying channel. The third shifting mechanism moves the edge blockers towards and away from each other to adjust the position of the cloth block in the middle between the two and on the material conveying channel. For the third shifting mechanism, a common belt linear slide type is adopted. The edge blockers 232 are fixedly arranged side by side on the parallel belts. The third shifting mechanism 231 is installed in the frame cavity below the material conveying channel. The plate forming the material conveying channel is formed with a cavity for the edge blockers to extend and move. The first material clamping and conveying assembly moves the cloth piece onto the material conveying channel between the two edge blockers.

[0085] Air holes 1001 can be selectively formed on the material conveying channel 14 between the two edge blockers and connected to an air extraction or blowing mechanism on the frame. During use, for example, when the first material clamping and conveying assembly feeds the material onto the material conveying channel, air can be discharged through the air holes to reduce friction, which helps improve the flatness of the fabric. For example, during the folding process of the folding mechanism, air extraction through the air holes for adsorption helps improve the stability of the fabric.

[0086] As Figures 1 - 4 , Figure 9As shown, in this example, the folding and feeding mechanism 3 is used to fold and convey the fabric transferred by the feeding mechanism to the first material transfer mechanism 4. The folding and feeding mechanism includes a fourth displacement mechanism 300, a second support 301, a third support 302, a second telescopic mechanism 303, a third telescopic mechanism 304, a fourth telescopic mechanism 306, and a fifth telescopic mechanism 305. Among them, the fourth displacement mechanism is located in the frame cavity below the corresponding material conveying channel. A gantry-type support 2 is installed at the moving end of the fourth displacement mechanism to move the support 2 along the material conveying channel. The second telescopic mechanism, such as a cylinder, is longitudinally installed on the support 2, and the third support is fixed at the moving end of the second telescopic mechanism. A first clamping plate 307, a third telescopic mechanism, and a fourth telescopic mechanism are installed on the third support. Among them, the first clamping plate 307 is located at the bottom end of the third support 302. A number of convex ends 309 are formed at intervals at the end of the first clamping plate 307. The number of convex ends are distributed at intervals along the length direction of the corresponding end in a tooth shape. A notch 1000 for the convex ends to pass through longitudinally is formed at the starting end of the material conveying channel, as Figure 6 shown. A second clamping plate 308 is installed at the telescopic end of the longitudinally fixed fourth telescopic mechanism. During use, the fourth displacement mechanism moves the support 2 until the second clamping plate passes over the end of the material conveying channel. The second telescopic mechanism moves the third support downward so that the first clamping plate is lower than the notch at the end of the material conveying channel. Then, the fourth displacement mechanism moves so that the first clamping plate is below the notch, and the second telescopic mechanism moves the third support upward. The convex ends on the first clamping plate pass through the notch longitudinally, and the end of the fabric placed at the notch is lifted synchronously. The fourth telescopic mechanism moves the second clamping plate downward longitudinally so that the second clamping plate and the first clamping plate clamp the fabric end in the middle.

[0087] As Figure 9 shown, in this example, the fifth telescopic mechanism 305 is horizontally fixed at the moving end of the third telescopic mechanism 304, and a push block 310 is fixed at the moving end of the fifth telescopic mechanism. The third telescopic mechanism reciprocates the push block longitudinally in front of the first clamping plate. When the first clamping plate and the second clamping plate are in a clamping state, the third telescopic mechanism moves the fifth telescopic mechanism downward until the push block is below the first clamping plate, and the fifth telescopic mechanism moves backward toward the first clamping plate, thereby pushing the fabric backward and simultaneously flattening the part of the fabric near the first clamping plate and the second clamping plate that clamps the fabric. Then, the fourth displacement mechanism moves along the length extension direction of the corresponding conveying channel (the moving direction of the fourth displacement mechanism is the same as the extension direction of the first section of the material conveying channel at this place) so that the clamped fabric end moves forward to complete folding. After the push block is reset, the second telescopic mechanism drives the first clamping plate to press the fabric piece on the material conveying channel, and under the drive of the fourth displacement mechanism, the fabric piece is displaced to the first material transfer mechanism. The first clamping plate and the second clamping plate are loosened, and the fourth displacement mechanism is reset.

[0088] Regarding the installation of the second displacement mechanism and the fourth displacement mechanism, as Figure 10As shown in the figure, an installation frame 203 is added. The installation frame is fixed in the frame cavity below the material conveying channel. A fourth displacement mechanism and a second displacement mechanism are installed on the frame-shaped installation frame. The fourth displacement mechanism includes a first synchronous belt 3001, a first driving wheel 3002, a first driving shaft 3003, and a first driving motor 3004. The second displacement mechanism includes a second synchronous belt 2104, a second driving wheel 2102, a second driving shaft 2103, and a second driving motor 2101. The two ends of the installation frame are respectively pivotally connected to the first driving shaft and the second driving shaft. The first driving shaft and the second driving shaft are correspondingly connected to the output ends of the first driving motor and the second driving motor. As Figure 10 shown, the output ends of the first driving motor 3004 and the second driving motor 2101 drive the corresponding driving shafts to rotate through belt and pulley transmission. Driving wheels are installed at both ends of the first driving shaft and the second driving shaft. The first driving wheels and the second driving wheels on the first driving shaft and the second driving shaft are correspondingly connected by a first synchronous belt and a second synchronous belt. The first driving wheel on the first driving shaft is fixedly connected, and the second driving wheel on the first driving shaft is rotatably connected. The second driving wheel on the second driving shaft is fixedly connected, and the first driving wheel on the second driving shaft is rotatably connected. The first synchronous belt and the second synchronous belt are respectively fixed to the bottom ends of the first bracket and the second bracket. Then, under the drive of the corresponding driving motors, the corresponding synchronous belts rotate, thereby moving the first bracket or the second bracket. The first synchronous belt and the second synchronous belt are both arranged along the extension direction of the material conveying channel where they are located. For the first driving motor and the second driving motor, they can be fixed on the frame or the installation frame. For each telescopic mechanism, a cylinder is used.

[0089] As Figures 1 - 4 , Figure 11 shown, in this example, the first material transfer mechanism 4 includes a fifth displacement mechanism 400, a sixth telescopic mechanism 401, a seventh telescopic mechanism 402, a fourth bracket 403, and a first pressing plate 404. The fifth displacement mechanism 400 is installed in the frame cavity below the middle section of the material conveying channel. The fourth bracket is fixed at the moving end of the fifth displacement mechanism 400. The fifth displacement mechanism moves the fourth bracket along the extension direction of the middle section of the material conveying channel. The fourth bracket is installed with the sixth telescopic mechanism. The seventh telescopic mechanism is installed at the telescopic end of the sixth telescopic mechanism. The first pressing plate is fixed at the telescopic end of the seventh telescopic mechanism. The sixth telescopic mechanism moves the seventh telescopic mechanism along the extension direction of the first section of the material conveying channel. The seventh telescopic mechanism moves the first pressing plate back and forth longitudinally. During use, when the folding feeding mechanism moves the fabric to the first material transfer mechanism, the sixth telescopic mechanism moves the seventh telescopic mechanism forward, and the seventh telescopic mechanism moves the first pressing plate downward to press the side of the folded fabric with the first pressing plate. Driven by the fifth displacement mechanism, the pressed fabric is moved to the first sewing mechanism. It is optional to form a hole groove for sewing the edge on the first pressing plate. When the hole groove is below the output end of the first sewing mechanism, the first sewing mechanism sews the side of the fabric pressed by the first pressing plate. Then, the first material transfer mechanism continues to drive the sewn fabric to the secondary folding mechanism. The material transfer mechanism can be selected as a lead screw type, a belt linear slide table type, etc. according to needs. Each telescopic mechanism is a cylinder.

[0090] As Figures 1 - 4 , Figure 13 shown, in this example, the secondary folding mechanism 6 includes a pressing mechanism 60, a displacement mechanism 61, a telescopic mechanism 62, a telescopic mechanism 63, a telescopic mechanism 64, a bracket 65, a bracket 66, and a pressing plate 67. Among them, the displacement mechanism 6 is installed on the frame on the side of the feeding channel. The bracket 65 is installed at the moving end of the displacement mechanism 6, and the displacement mechanism 6 moves the bracket 65 along the extending direction of the middle section of the feeding channel where it is located. The telescopic mechanism 62 is installed longitudinally on the bracket 65. The bracket 66 is fixed at the moving end of the telescopic mechanism 62. The telescopic mechanism 63 and the telescopic mechanism 64 are installed longitudinally on the bracket 66. Among them, the clamping plate 68 is fixed at the moving end of the telescopic mechanism 63, and the clamping plate 69 is fixed on the bracket 66 below the clamping plate 68. The telescopic mechanism 63 reciprocates longitudinally above the clamping plate 69 to move the clamping plate 68 so that the clamping plate 68 and the clamping plate 69 cooperate to clamp or release the fabric located in the middle. Preferably, the corresponding surfaces at the ends of the clamping plate 68 and the clamping plate 69 are both inclined surfaces to facilitate the entry of the end of the fabric.

[0091] The pressing plate 67 is fixed at the telescopic end of the telescopic mechanism 64, and the telescopic mechanism 63 is located between the telescopic mechanism 64 and the telescopic mechanism 62. For the pressing mechanism 60, as Figure 20 shown, the pressing mechanism 60 is installed at the opposite side positions of the feeding channel respectively. The two groups of pressing mechanisms help to improve the stability of the folding process. The pressing mechanism 60 includes a telescopic mechanism 600, a telescopic mechanism 601, and a pressing plate 602. The telescopic mechanism 601 is horizontally fixed at the moving end of the telescopic mechanism 600. The telescopic mechanism 600 is located in the frame cavity below the feeding channel at this position. The pressing plate 602 is fixed at the moving end of the telescopic mechanism 601, and the telescopic mechanism 601 expands and contracts along the extending direction of the first section of the feeding channel.

[0092] During use, after the fabric to be pressed by the material moving mechanism 1 moves to the predetermined position, the telescopic mechanism 600 moves up the telescopic mechanism 601. The telescopic mechanism 601 moves forward so that the pressing plate 602 is above the end of the fabric and moves down to press the end of the fabric. The telescopic mechanism 62 moves down so that the clamping plate 68 abuts or approaches the feeding channel. Then, driven by the displacement mechanism 6, the clamping plate 68 moves forward to abut the end of the fabric and makes the end of the fabric enter between the clamping plate 68 and the clamping plate 69. The clamping plate 68 moves down to cooperate with the clamping plate 69 to clamp the end of the fabric in the middle. Then, the material moving mechanism 1 releases the pressing on the fabric and resets. The displacement mechanism 6 moves forward so that the clamped end of the fabric moves forward to form a fold. The clamping plate 68 and the clamping plate 69 release the clamping. The telescopic mechanism 64 moves down the pressing plate 67 so that the pressing plate 67 presses down on the sewn side, which helps the side to separate from the clamping plate 68 and the clamping plate 69 and makes the side in a flat state. The pressing plate 67 resets, the material moving mechanism 1 disengages from the pressing on the fabric and resets. Then, the material moving mechanism 2 moves the fabric after secondary folding to the sewing mechanism 2 and the second clamping and conveying assembly in sequence.

[0093] For the material moving mechanism 2, its structure and action are the same as those of the material moving mechanism 1. AsFigure 12 As shown. In addition, the first material transfer mechanism may further include a first edge pressing mechanism, such as Figure 11 shown. The first edge pressing mechanism includes an eighth telescopic mechanism 405, a pivot 406 and a second pressing plate 407. The eighth telescopic mechanism is pivotally connected to the fourth bracket and its telescopic end is pivotally connected to a fixed block 408. The fixed block is pivotally connected to the pivot and the end of the pivot is pivotally connected to the fourth bracket. The second pressing plate is fixed on the pivot. The second pressing plate is at the end of the first pressing plate. The telescopic movement of the eighth telescopic mechanism can cause the pivot to rotate, thereby moving the first pressing plate and pressing the end of the fabric, which helps to keep the fabric flat during the movement.

[0094] The transfer directions of the first material transfer mechanism, the second material transfer mechanism and the sixth displacement mechanism are the same.

[0095] When the second material transfer mechanism moves the fabric to the second sewing mechanism, the second sewing mechanism sews the side of the fabric that has been folded twice and sewn once on the edge again. After that, the second material transfer mechanism moves the sewn fabric to the second clamping and conveying assembly.

[0096] Such as Figures 1 - 4 , Figure 14 shown. In this example, the second clamping and conveying assembly 9 includes a displacement assembly, a first rotating shaft 904, a second pressing mechanism 905, an opening mechanism 906, and a driving motor 907. The opening mechanism opens the fabric port. The displacement assembly inserts the two first rotating shafts into the opened port and tightens them. The displacement assembly transfers the tightened fabric to the eversion mechanism.

[0097] The displacement assembly includes a seventh displacement mechanism 900, an eighth displacement mechanism 901, a ninth displacement mechanism 902, and a seventh bracket 903. The seventh displacement mechanism 900 is installed on the frame, such as a lead screw type or a belt linear slide type. The mobile end of the seventh displacement mechanism is installed with the seventh bracket. The seventh displacement mechanism moves the seventh bracket 903 along the extending direction of the tail section of the conveying channel. The bottom end of the seventh bracket is installed with the eighth displacement mechanism, such as a lead screw type or a belt linear slide type. The mobile end of the eighth displacement mechanism is installed with an eighth bracket 908. The ninth displacement mechanism is installed on the eighth bracket, such as a belt linear slide type. The driving motor is installed in parallel on the mobile end of the ninth displacement mechanism, such as the driving motor is installed in parallel on the parallel belts. The output end of the driving motor is fixed with the first rotating shaft along the extending direction of the middle section of the conveying channel. The ninth displacement mechanism moves the driving motor towards or away from each other to make the two first rotating shafts perform an opening and closing action. The transfer direction of the eighth displacement mechanism is the same as that of the second material transfer mechanism, and the transfer direction of the seventh displacement mechanism is perpendicular to the transfer direction of the eighth displacement mechanism.

[0098] Such as such as Figures 1 - 3 , Figure 22As shown, the second pressing mechanism includes a telescopic mechanism fourteen 9051 and a pressing plate five 9052. The second pressing mechanism is installed at the frame at the end of the middle section of the feeding channel. The telescopic mechanism fourteen 9051 is installed on the frame and the pressing plate five 9052 is fixed at its moving end. The telescopic mechanism fourteen reciprocates vertically to press or disengage from the fabric on the feeding channel. The opening mechanism 906 includes a telescopic mechanism sixteen 9061 and a suction cup mechanism two 9062. The opening mechanism is located on the frame at the end of the middle section of the feeding section. The suction cup mechanism two is installed at the telescopic end of the telescopic mechanism sixteen. The suction cup mechanism two is consistent with the suction cup mechanism one and reciprocates vertically.

[0099] During use, after the second edge-sewing fabric is moved to a predetermined position by the second material transfer mechanism, the pressing plate five in the second pressing mechanism moves downward to press the other side of the fabric opposite to the second edge-sewing position. The suction cup mechanism two in the opening mechanism moves downward to adsorb the top layer of the fabric and then moves upward to create a gap between the top surface and the lower fabric layer, that is, the end of the fabric is in an open state. In this example, the port of the fabric cylinder formed after the first folding is opened. Then, driven by the eighth displacement mechanism, the two first rotating shafts extend into the opened port and the ninth displacement mechanism moves the two first rotating shafts away from each other to tighten the fabric. The suction cup mechanism two disengages from the adsorption and the second pressing mechanism disengages from the pressing. In the tightened state, the fabric is moved to the turning-outward mechanism by the seventh displacement mechanism.

[0100] As Figures 1 - 3 , Figures 17 - 19As shown, the eversion mechanism 10 includes a displacement mechanism ten 100, a displacement mechanism eleven 101, a displacement mechanism twelve 102, a displacement mechanism thirteen 103, a bracket nine 104, a bracket ten 105, a strut one 106, and a jaw mechanism 107. The displacement mechanism ten and the displacement mechanism twelve are installed on the frame on one side of the end of the stroke of the displacement mechanism seven. The displacement mechanism ten and the displacement mechanism twelve are installed at intervals longitudinally. The bracket nine is installed at the mobile end of the displacement mechanism ten. For the displacement mechanism ten, it can be of the type such as a lead screw, a belt linear slide. The displacement mechanism eleven is installed on the bracket nine and the jaw mechanism is installed relatively at its mobile end. The displacement mechanism eleven is such as a belt linear slide module. The jaw mechanism is installed on the parallel belts respectively. The jaw mechanism is of the type such as a pneumatic cylinder jaw, and the jaw mechanism is moved towards or away from each other by the displacement mechanism eleven. The bracket ten is installed at the mobile end of the displacement mechanism twelve located below. The displacement mechanism twelve is such as a pneumatic cylinder, etc. The moving direction of the displacement mechanism twelve is the same as that of the displacement mechanism ten. The displacement mechanism thirteen is installed on the bracket ten. The strut one is installed in parallel at the mobile end of the displacement mechanism thirteen and the strut one is moved towards or away from each other by the displacement mechanism thirteen. The displacement mechanism thirteen is such as a belt linear slide module. For example, the strut one is installed on the parallel belts respectively. The two strut ones are located between the two jaw mechanisms. When the displacement mechanism seven moves the fabric to a predetermined position, the displacement mechanism ten and the displacement mechanism eleven cooperate to adjust the front and rear positions of the jaw mechanism and the distance between the jaw mechanisms until the jaw mechanisms are respectively on both sides of the fabric. Then the edge side of the fabric is clamped by the jaw mechanisms. The position of the strut one is synchronously advanced. When the jaw mechanism moves backward, the fabric is abutted by the strut one to turn it outwards onto the strut one. The eversion action of the eversion mechanism causes the inner wall to become the outer wall, which helps to hide the seam edge and improve the aesthetics. Then the jaw mechanism releases the clamping and resets.

[0101] Such as Figures 1 - 3 , Figures 15 - 16As shown, in this example, the stretching mechanism 11 includes a second support rod 110, a fourteenth displacement mechanism 111, a fifteenth displacement mechanism 112, a sixteenth displacement mechanism 113, and an eleventh bracket 114. The stretching mechanism is installed opposite to the eversion mechanism. The stretching mechanism is located below the seventh displacement mechanism. The fourteenth displacement mechanism is installed on the frame. A fixed mounting seat 115 is installed at the moving end of the fourteenth displacement mechanism, and the mounting seat reciprocates longitudinally. The fourteenth displacement mechanism is, for example, a cylinder. The fifteenth displacement mechanism is installed on the mounting seat, and the eleventh bracket is installed at the moving end of the fifteenth displacement mechanism. The fifteenth displacement mechanism is, for example, a cylinder. The sixteenth displacement mechanism is installed on the eleventh bracket, and the second support rods are installed in parallel at the moving end of the sixteenth displacement mechanism. The sixteenth displacement mechanism is, for example, a belt linear slide module. For example, the second support rods are respectively installed on the parallel belts to make the two second support rods perform opening and closing actions. After the fabric is everted, the longitudinal position is adjusted by the fourteenth displacement mechanism, and the front and rear positions are adjusted by the fifteenth displacement mechanism. In cooperation, the second support rods are inserted into the ports of the everted fabric. When inserting into the fabric ports, the second support rods are moved towards each other by the sixteenth displacement mechanism to tighten the fabric. The first support rods move towards each other and then move backward to separate from the fabric. Then, the second support rods are opened and closed by the sixteenth displacement mechanism to tighten and loosen the fabric so that the ribbing on the fabric appears.

[0102] As Figures 1 - 4 As shown, the blanking mechanism 12 includes a conveying component 120, a pushing component 121, and a first baffle 122. Among them, the conveying component passes between the stretching mechanism and the eversion mechanism, and the conveying component adopts a conveyor belt type. The first baffle 122 is fixed on the side frame of the conveying component. The first baffle is higher than the position of the belt in the conveying component. The first baffle is located below the second support rods. After the stretching mechanism performs a predetermined action on the fabric, the longitudinal and front and rear positions are adjusted by the fourteenth displacement mechanism and the fifteenth displacement mechanism so that the first baffle is located between the two second support rods. During the backward movement of the second support rods, the first baffle is used for limiting so that the fabric on the second support rods falls off onto the belt in the conveying component.

[0103] The pushing component 121 is installed on the side frame behind the first baffle along the conveying direction to push down the fabric conveyed by the conveying component. The pushing component includes a fifteenth telescopic mechanism 1211 and a pushing plate 1212. The fifteenth telescopic mechanism is arranged in the frame cavity behind the pushing plate. The pushing plate is installed at the telescopic end of the fifteenth telescopic mechanism. A storage tank 1213 is arranged on the corresponding frame on the other side of the conveying component along the telescopic direction of the fifteenth telescopic mechanism. Preferably, the telescopic direction of the fifteenth telescopic mechanism is perpendicular to the conveying direction of the conveying component. When the conveying component moves the fabric to the pushing component, the pushing component pushes the fabric on the conveyor belt into the storage tank, which is convenient for subsequent centralized transfer and processing.

[0104] As Figures 1 - 3As shown in the figure, a control end 13 is added, and the control end is connected to the action execution mechanisms on the frame such as the feeding mechanism, the folding and feeding mechanism, the first material transfer mechanism, the first sewing mechanism, the secondary folding mechanism, the second material transfer mechanism, the second sewing mechanism, the second clamping and conveying assembly, the outer turning mechanism, the stretching mechanism, and the blanking mechanism. According to the predetermined program in the control end, it is convenient for automatic control operation.

All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
