[0028] The utility model will be further described below in conjunction with the accompanying drawings.

[0029] like Figure 1 The neckline rib folding and stacking machine shown in the figure comprises a machine platform 100, the machine platform 100 comprises a table, the machine platform 100 is provided with a feeding unit 600 capable of gradually conveying the stacked neckline rib cloth pieces upward, a grabbing unit 700 capable of grasping the neckline rib cloth piece on the uppermost layer of the feeding unit 600 onto the table, a folding unit 200 capable of folding the neckline rib cloth piece on the table in the length direction, and a folding unit 200 capable of pressing and conveying the double-layer neckline rib cloth piece after folding to the first layer. A sewing machine 1000 has a pressing and feeding unit 300 for sewing the beginning of a double-layer neckline rib cloth piece, a stop turning unit 400 for folding the upper stop of the ring-shaped neckline rib cloth piece 180 degrees after sewing, and a stacking and pressing unit 500 and a material receiving unit 800 for stacking and sewing the stacked ring-shaped neckline rib cloth pieces, and stacking the folded end of the stop of the ring-shaped neckline rib cloth piece in the width direction, and holding the stacked ring-shaped neckline rib cloth pieces and conveying them to a second sewing machine 2000 for reinforcing and sewing the stacked ring-shaped neckline rib cloth pieces.

[0030] The feeding unit 600 first delivers the ribbed fabric piece to a suitable position under the table 100. Then, the grabbing unit 700 grabs the fabric piece and places it accurately on the table. The folding unit 200 then folds the collar ribbed fabric piece in half to form a double-layer fabric piece. At this time, the pressing unit 300 will tightly press the folded fabric piece and stably deliver it to the first sewing machine 1000 for stitching.

[0031] After the seaming is completed, the workflow is transferred to the stopper turning unit 400, which can turn the upper stopper 180° to form a folded cloth piece. Next, the stacking and pressing unit 500 stacks the folded cloth piece in the width direction and continues to convey it to the second sewing machine 2000 for sewing and reinforcement at the sewn seams. Finally, the reinforced collar rib cloth piece is collected by the material receiving unit 800, thus completing the entire processing process.

[0032] The neckline rib crease and stacking machine integrates multiple processes in one, realizes continuous operation from raw materials to finished products, and significantly improves production efficiency. The equipment can accurately fold and fold ribbed cloth pieces, and reinforce and sew at precise positions to ensure good product quality. The equipment realizes the full-automatic crease and stacking of neckline ribs, reduces labor intensity, and reduces labor costs. The equipment is suitable for the crease and stacking processing of various neckline ribs and has strong versatility. In short, the neckline rib crease and stacking machine of the utility model not only makes the crease and stacking steps of the neckline ribs in one go, improves production efficiency, but also realizes automated operation, reduces manual operation links, and improves production accuracy and stability.

[0033] The specific structure of each unit is as follows:

[0034] like Fig.11 The feeding unit 600 includes a feeding fixed vertical plate 601 fixedly mounted under the table top of the machine table 100, a third guide rail 602 with a stroke in the up-down direction, a third screw rod 603 with a rotation axis in the up-down direction, a third slider 604 slidingly matched with the third guide rail 602, the third screw rod 603 is driven by a third motor 605, the third screw rod 603 is screwed with a third nut, the third nut is fixedly connected to the third slider 604, the third slider 604 is also fixedly connected to two feeding movable vertical plates 606, and the upper ends of the two feeding movable vertical plates 606 are fixedly connected to a floating support plate 607; the feeding fixed vertical plate 601 is also fixedly connected to a feeding fixed flat plate 608, the feeding fixed flat plate 608 is located below the floating support plate 607, and a fourth guide rail 609 with a stroke in the left and right direction, a fourth screw rod 610 with an axial rotation in the left and right direction, and a fourth slider slidably matched with the fourth guide rail 609 are fixed on the loading fixed plate 608. The fourth screw rod 610 is driven by a fourth motor 611, and the fourth screw rod 610 is threadedly connected with a fourth nut, and the fourth nut is fixedly connected to the fourth slider, and the fourth slider is also fixedly connected to two vertical shifting rods 612; a fixed support plate 613 is also suspended and fixedly connected above the loading fixed plate 608, and two long holes 614 with a length in the left and right direction are opened on the fixed support plate 613, and two shifting rods 612 pass through the two long holes 614 respectively with a gap and are fixedly connected to a push plate 615.

[0035] When the feeding process begins, the third screw rod 603 driven by the third motor 605 starts to rotate. Since the third screw rod 603 is screwed to the third nut fixed to the third slider 604, the third slider 604 moves up and down along the third guide rail 602. A floating support plate 607 is fixed to the loading movable vertical plate 606 fixed to the third slider 604. When the third slider 604 moves up and down, the loading movable vertical plate 606 and the floating support plate 607 thereon also move with it. The up and down movement of the floating support plate 607 realizes the lifting and lowering of the neckline ribbed cloth piece. When the cloth piece is lifted to a certain position, the third motor 605 stops working. At this time, the fourth screw rod 610 driven by the fourth motor 611 starts to work. Since the fourth screw rod 610 is screwed to the fourth nut of the fourth slider, when the fourth screw rod 610 starts to rotate, the fourth slider starts to move left and right. The two levers 612 fixed to the fourth slider are linked to the push plate 615. When the fourth slider moves left and right, the two levers 612 will dynamically adjust the position of the push plate 615. When the position of the push plate 615 is adjusted to a suitable state, it will push the neckline rib cloth piece at this position from the floating support plate 607 to the table of the machine table 100, which is exactly the position where the grabbing unit 700 can grab it. In this way, a complete loading process is completed. During the whole process, the precise coordination between the motor, screw rod, slider, vertical plate and other components can accurately deliver the neckline rib cloth piece to the grabbing unit 700, preparing for the subsequent folding, sewing and other processes. This whole set of delicate and complex process of coordinated work of various components greatly improves the accuracy and degree of automation of quality control, and significantly improves production efficiency.

[0036] like Figure 12-13 The material grabbing unit 700 includes a fourth linear module 701 fixed on the machine table 100 with a stroke in the left-right direction, a material grabbing vertical plate 702 fixed on the slide of the fourth linear module 701, and fifth guide rails 703 with a stroke in the up-down direction are fixed on the front and rear surfaces of the material grabbing vertical plate 702 respectively, and two fifth sliders 704 respectively slidingly matched with the two fifth guide rails 703 are fixedly connected to a cantilever 705 in the front-to-back direction. The material grabbing vertical plate 702 is also fixedly connected to a twelfth cylinder 710 with a stroke in the up-down direction. The piston rod of the cylinder 710 is connected to the cantilever 705; at least one slide groove 706 with a stroke in the up and down direction is fixedly arranged at one end close to the cantilever 705 connected to the fifth slider 704 and the free end close to the cantilever 705, and the slide groove 706 slides in the slide rod 707, and a limit block 709 is fixed at the upper end of the slide rod 707 and a needle-punched cloth grabber 708 is fixed at the lower end. A spring is sleeved on the slide rod 707 between the slide groove 706 and the needle-punched cloth grabber 708; the position of the slide groove 706 in the front and rear directions of the cantilever 705 is adjustable.

[0037] First, the fourth linear module 701 is used to control the left and right movement of the material grabbing plate 702, so as to locate the cloth piece. The material grabbing plate 702 is combined with the fifth slider 704 and the fifth guide rail 703, and can move in the up and down directions to change the height of the cloth grabbing. The up and down movement of the material grabbing plate 702 is controlled by the twelfth cylinder 710 fixed thereto, and the piston rod is connected to the cantilever 705. A cantilever 705 is fixed on the material grabbing plate 702, and at least one up and down slide groove 706 is fixed at both ends of the cantilever, and a slide rod 707 is slidably matched in the slide groove. A limit block 709 is fixed at the upper end of the slide rod, and a needle-punched cloth grabber 708 is fixed at the lower end. A spring is sleeved on the slide rod 707 to achieve a certain degree of pressure and bounce back after the cloth grabber 708 contacts the cloth piece. At the beginning of the material grabbing process, the twelfth cylinder 710 drives the cantilever 705 to move downward, and through the slide groove 706 and the spring on the slide bar 707, the needle-punched cloth grabber 708 is pressed against the cloth piece. When the needle-punched cloth grabber 708 contacts the cloth piece, the downward force will continue to grasp the cloth piece through the spring on the slide bar 707. At the same time, the upper end limit block 709 of the slide bar 707 limits the further downward movement of the slide bar 707, so that the needle-punched cloth grabber 708 grasps the cloth piece. After grasping the cloth, the twelfth cylinder 710 retracts the piston, and the cantilever 705, the slide bar 707 and the needle-punched cloth grabber 708 rise together, taking the cloth piece away from its original position. Finally, through the fourth linear module 701, the material grabbing vertical plate 702 and the fifth slider 704, the cantilever 705, the needle-punched cloth grabber 708 and a whole set of linkage structures thereon are driven to move to the right to the predetermined position, completing the positioning of the cloth piece and preparing for the next process. Each component plays an important role in the material grabbing process, and the coordination between them can effectively improve the accuracy and efficiency of the material grabbing process, ensuring smooth grabbing of the fabric for subsequent folding, pressing and feeding operations. The needle-punched fabric grabber is an existing technology and will not be described in detail.

[0038] like Figure 2-4The material folding unit 200 includes a gantry 201 fixed on the table top of the machine 100. The gantry is fixed on the table top of the machine 100 to provide a stable support structure for the material folding unit 200. A first linear module 202 with a stroke in the front-to-back direction is fixed under the crossbeam of the gantry 201. The module is responsible for moving in the front-to-back direction. A material folding vertical plate 203 is fixed on the slide of the first linear module 202. A first guide rail 204 in the left-right direction is fixed on the material folding vertical plate 203. A first screw rod 205 with an axial direction in the left-right direction is rotatably arranged. A first slider 206 with a sliding fit of the first guide rail 204 is slidably fitted. The first screw rod 205 is driven by a first motor 207. The first motor 207 provides power for the first screw rod 205 to achieve precise linear movement. The first screw rod 205 is screwed to the first nut, the first slider 206 is fixed to the first nut and the movable upright plate 210, the front side of the movable upright plate 210 is fixed with a first cylinder 208 with a stroke in the up-down direction, and a lower clamping plate 209 is fixed on the piston rod of the first cylinder 208; the rear side of the movable upright plate 210 is fixed with a second cylinder 211 with a stroke in the up-down direction, and an upper clamping plate 212 is fixed on the piston rod of the second cylinder 211, and the lower clamping plate 209 and the upper clamping plate 212 form a pressing pair for clamping one end of the collar ribbed cloth piece; the rear side of the movable upright plate 210 is also fixed with a third cylinder 213 with a stroke in the up-down direction, and a high-pressure air pipe 214 is fixed on the piston rod of the third cylinder 213, and the left and right axial sections of the high-pressure air pipe 214 are located behind the upper clamping plate 212 and the lower clamping plate 209, and a plurality of air outlets facing the upper clamping plate 212 and the lower clamping plate 209 are provided on the left and right axial sections of the high-pressure air pipe 214. The high-pressure air pipe 214 is used to provide high-pressure air to blow the fabric to make it fit.

[0039] When folding the material, the ribbed cloth piece has been accurately captured by the material grabbing unit 700 and is located at a preset position. The first cylinder 208 is started, driving the lower clamping plate 209 to move downward and reach one end of the cloth piece. The lower clamping plate 209 moves to the bottom and shovels into one end of the cloth piece. Next, the second cylinder 211 is started, driving the upper clamping plate 212 to move downward, so that one end of the cloth piece is tightly clamped by the upper clamping plate 212 and the lower clamping plate 209. Then, the first motor 207 is started, driving the first screw rod 205 to move all components including the upper and lower clamping plates fixed on the movable vertical plate 210 toward the other end of the cloth piece. This stretches the cloth piece from one end to the other end to achieve folding. When the folding is completed, the second cylinder 211 reacts, and the upper clamping plate 212 moves upward and releases the cloth piece. At this time, the third cylinder 213 is started, driving the high-pressure air pipe 214 to blow air to the cloth piece, so that the upper end of the cloth piece and its lower end are tightly attached together, which is equivalent to completing the folding action. Finally, all components are reset and ready to start the next folding cycle. Through fine control and precise fabric handling, the equipment can ensure that each fold is at the exact position and angle, thus meeting the requirements of quality precision and high efficiency in production.

[0040] like Figure 5-7 The pressure-feeding unit 300 includes a second linear module 301 directly or indirectly fixed on the table 100 with a stroke in the left-right direction, a second guide rail 302 with a forward-backward direction fixed on the slide of the second linear module 301, a second screw rod 303 with a rotation axis in the forward-backward direction, a second slider 305 slidably matched with the second guide rail 302, the second screw rod 303 is driven by a second motor 304, the second screw rod 303 is screwed with a second nut, the second nut is fixedly connected to the second slider 305, and the second slider 305 is also fixedly connected to an L-shaped pressure-feeding vertical plate 306, and the free end of the pressure-feeding vertical plate 306 is fixedly provided with a fixed pressure-feeding plate 307 close to the table 100, and the fixed pressure-feeding plate 307 is provided with a left-right long direction. A needle groove in the right direction, an avoidance groove 311 is provided on the pressure delivery plate 306 above the fixed pressure delivery plate 307; the front side of the pressure delivery plate 306 is fixedly provided with a fourth cylinder 308 with a stroke in the up and down directions, an upper pressure plate 309 is fixedly provided on the piston rod of the fourth cylinder 308, and a needle groove corresponding to the needle groove on the fixed pressure delivery plate 307 is provided on the upper pressure plate 309; the rear side of the pressure delivery plate 306 is fixedly provided with a fifth cylinder 310 with a stroke in the up and down directions, an intermediate clamping plate 312 is fixedly provided on the piston rod of the fifth cylinder 310, and the front end of the intermediate clamping plate 312 passes through the avoidance groove 311 and is located between the upper pressure plate 309 and the fixed pressure delivery plate 307, and does not exceed the needle groove on the upper pressure plate 309 and the fixed pressure delivery plate 307.

[0041] First, the second motor 304 is started to drive the second screw rod 303 to rotate, causing the second slider 305 to start moving left and right on the second guide rail 302, thereby driving the pressure feed plate 306 to move. When the pressure feed plate 306 moves to a specific position, the fifth cylinder 310 on the rear side is started, so that the middle clamping plate 312 passes through the avoidance groove 311 and moves to the position between the upper pressing plate 309 and the fixed pressure feed plate 307. In this way, the upper layer of the ribbed cloth piece will enter between the upper pressing plate 309 and the middle clamping plate 312, and the lower layer of the ribbed cloth piece will enter between the middle clamping plate 312 and the fixed pressure feed plate 307. This design effectively isolates the upper and lower fabric layers. Subsequently, the second motor 304 stops, and the pressure feed plate 306 and the fixed pressure feed plate 307 stop moving, fixing the fabric at a specific position. Then, the fourth cylinder 308 on the front side is started to drive the upper pressing plate 309 to move downward, pressing tightly on the fabric at the upper end, and preparing for the sewing process. When a portion of the fabric is sewn, the fourth cylinder 308 and the fifth cylinder 310 are started again, and the upper pressure plate 309 and the middle clamp plate 312 rise respectively, releasing the fabric and preparing for the next round of movement and sewing. This process will be repeated until the entire fabric is sewn. The design of the three-layer clamp plate group, namely the fixed pressure plate 307 below, the upper pressure plate 309 and the middle clamp plate 312 above, their coordinated work can achieve smooth movement of the fabric, effectively isolate the upper and lower fabric layers, and keep the fabric close during sewing. The design of the entire unit takes into account the accuracy of operation and production efficiency to meet excellent production needs.

[0042] like Figure 8 The stopper flap unit 400 includes a first slide cylinder 401 which is directly or indirectly fixed on the table top of the machine 100 and has a stroke in the left-right direction, a sixth cylinder 402 which is fixed on the slide of the first slide cylinder 401 and has a stroke in the front-back direction, a seventh cylinder 403 which is fixed on the piston rod of the sixth cylinder 402 and has a stroke in the up-and-down direction, and an L-shaped stopper flap 404 which is fixed on the piston rod of the seventh cylinder 403.

[0043] The stopper unit 400 first moves in the left and right directions through the first slide cylinder 401, which is specifically controlled by the first slide cylinder 401. When the first slide cylinder 401 moves to the appropriate position, the front and back movements can be controlled by the sixth cylinder 402. At the same time, the up and down movements are controlled by the piston rod of the seventh cylinder 403 in the vertical direction. This design allows the stopper flap 404 to be accurately deployed at any position in the space, thereby realizing the flipping operation of the upper layer of the ribbed cloth piece. The entire process is completed by the cylinders working alternately back and forth, so that the upper layer of the ribbed cloth piece can be flipped in a precise and free manner.

[0044] like Figure 9-10The stacking and pressing unit 500 includes a third linear module 501 which is directly or indirectly fixed on the table 100 and has a stroke in the left-right direction. The slide of the third linear module 501 is fixed with an eighth cylinder 502 and a ninth cylinder 503 which have a stroke in the front-back direction. The piston rod of the eighth cylinder 502 is fixed with a tenth cylinder 504 which has a stroke in the up-down direction. The piston rod of the tenth cylinder 504 is fixed with a stacking plate 505. The lower end of the stacking plate 505 is bent 90 degrees to form a lower pinching finger 506. The stacking plate 505 is also fixed with an eleventh cylinder 507 which has a stroke in the up-down direction. The piston of the eleventh cylinder 507 An upper pinching finger 508 is fixedly connected to the rod, and the upper pinching finger 508 and the lower pinching finger 506 form a pinching pair for clamping one end of the collar ribbed cloth piece; a fixed stacking feeding plate 509 is fixedly connected to the piston rod of the ninth cylinder 503, and a movable stacking feeding plate 510 that can slide up and down relative to the fixed stacking feeding plate 509 is sleeved on the fixed stacking feeding plate 509, and the lower surface of the movable stacking feeding plate 510 has a step surface that is lower in the front and higher in the back, and a needle groove with a long direction in the left and right direction is provided on the relatively lower front surface; a circular hole with an axial direction in the up and down direction is also provided on the movable stacking feeding plate 510, and a screw 511 is screwed to the fixed stacking feeding plate 509 after a gap is passed through the circular hole, and a spring is sleeved on the rod of the screw 511.

[0045] First, the upper pinching finger 508 and the lower pinching finger 506, this pair of pinching pairs are used to pinch one end of the collar ribbed cloth piece. Under the control of this pair of pinching pairs, the end of the grabbed ribbed cloth piece will move toward the other end of the cloth piece, and the other end of the cloth piece will be pressed by the step surface with a lower front and a higher back. When the upper pinching finger 508 and the lower pinching finger 506 release the clamping of the end of the ribbed cloth piece, this end will extend into the unpressed area of ​​the step surface. Finally, the newly arrived end of the cloth piece is pressed by the step surface together with the part of the cloth piece that has been pressed. After this action is completed, the overall position of the ribbed cloth piece is stabilized and can be safely moved to the next position. Finally, the stacking and pressing unit drags the ribbed cloth piece that has been sorted in this way to the second sewing machine. Here, a stitch of about 1 cm will be reinforced on the cloth piece.

[0047] After the sewing process is completed, the stacking and pressing unit releases the collar rib fabric piece with the reinforcement stitches. At this time, the material throwing plate 807 will be driven to rotate by the thirteenth cylinder 805 to transfer the collar rib fabric piece with the reinforcement stitches to the receiving hopper 802. When the height of the collar rib fabric piece in the receiving hopper 802 is detected by the photoeye 804, it means that the receiving hopper 802 has reached a certain filling level. At this time, the fifth linear module 801 will drive the receiving hopper 802 to move downward, releasing more space to store more rib fabric pieces. When the set number is reached, the receiving hopper 802 can be emptied. The rib fabric pieces can be effectively collected and stored after the sewing step is completed, which improves work efficiency.
