Description

Technical Field

[0001] This utility model relates to the field of bag opening machine technology, specifically an automated fabric bag opening machine. Background Technology

[0002] In the garment manufacturing industry, especially when making pockets for trousers, jackets, and other garments, opening the pocket is a crucial and complex process. Traditionally, the pocket-opening process relies heavily on skilled workers operating manually. This typically involves positioning the pocket lining (pocket lip), marking the pocket opening on the garment piece, manually cutting the opening, manually folding the pocket edge inwards (i.e., hemming) to create a smooth edge, and finally sewing it in place using a sewing machine. This purely manual operation mode has significant drawbacks: firstly, it demands extremely high levels of skill and experience from the workers, resulting in high training costs; secondly, it has low production efficiency, making it difficult to meet the demands of large-scale production; and thirdly, the product quality is inconsistent, as the width and smoothness of the hem, as well as the evenness of the stitching, depend entirely on the worker's condition, easily leading to defective products.

[0003] To improve automation, some semi-automatic bag-opening machines have emerged on the market. These machines typically use templates or simple pneumatic clamps to hold the fabric in place, but the core "hemming" step still largely requires manual intervention or is completed step-by-step through multiple complex independent mechanisms, resulting in incomplete automation. Existing fully automatic solutions also have significant drawbacks: for example, the lack of dynamic coordination between the hemming and pressing mechanisms can easily lead to uneven hemming, wrinkles, or even fabric damage due to excessive pressure on the fabric during the hemming process; secondly, the connections between various workstations in the entire production process (such as feeding, cutting, hemming, and sewing) are not smooth enough, resulting in waiting time and limiting further improvements in overall efficiency; furthermore, the equipment has poor versatility and struggles to quickly adapt to different sizes, materials, and bag types.

[0012] The operator lays the fabric to be opened flat on the pressure plate, so that it covers the rectangular groove area corresponding to pressure strip one and pressure strip two; The large and small pressure frames respectively drive the pressure strips one and two, fixed inside them, through the rectangular grooves on the pressure plate, firmly pressing the fabric against the surface of the pressure plate. At this point, the fabric is completely fixed; The clamping components include cylinder four, clamping plate one, cylinder five, clamping plate two, cylinder six, side positioning component, cylinder seven, upper positioning component, cylinder eight, and lower positioning component.

One set of cylinder ten is fixedly connected to the front cover plate, and the other set of cylinder ten is fixedly connected to the rear cover plate.

[0016] The cylinder ten of the movable cover plate retracts, and the cylinder nine extends, pulling the front and rear cover plates down and open to make room for the folded edges.

[0017] The frame pressing assembly descends via its lifting cylinder, bringing the pressing plate and the pressed fabric close to the material feeding mechanism of the hem folding assembly, while maintaining the pressed state.

[0018] The front and rear feeders are activated. Motor 1 drives pulley 2 and the double-acting lead screw to rotate via belt 1.

[0019] Two opposing threads on the bidirectional lead screw drive two material-grabbing claws to move towards each other along the motion track.

[0020] As the fabric-pulling claws pull the front and rear edges of the fabric inward, the pressing components respond in the corresponding areas. For example, cylinder two or three may release or lift a small amount of pressure, allowing the fabric to bend and fold smoothly inward while being pulled, rather than being pressed down. Simultaneously, cylinders four and five at clamping plates one and two are activated, pushing clamping plates one and two inward to fold the fabric. Subsequently, cylinders seven and eight are activated, pushing the upper and lower positioning components inward to press and flatten the folded fabric, ensuring a neat fold line. After the front and rear folds are completed, the front and rear pulling components reset.

[0021] The left and right feeding components are activated. First, motor two drives screw one to rotate, which moves the fixed plate along guide rail two, causing the entire left and right feeding mechanism to move to the working position.

[0022] Next, the motor starts, driving the lead screw to rotate, causing the two material feeders to move towards each other on the fixed track.

[0023] Similarly, after the left and right material-ejecting plates have finished ejecting the material, cylinder six is ​​activated. Cylinder six drives the side plate positioning component, causing the side positioning block to move inward, folding the left and right fabric edges. At the same time, the pressing component coordinates and relaxes in the corresponding left and right areas. This fixes the completed front and rear folded parts, ensuring that the left and right folds are not disturbed. Two sets of clamping cylinders are fixedly connected to the back of the fixed platform, and the clamping cylinders correspond to the cloth support plate.

[0024] The lifting cylinder of the pressing frame assembly drives the entire assembly downward, precisely pressing the fabric onto the bag lip of the support plate. At this time, the clamping cylinder on the back of the fixing table activates, clamping the support plate below, temporarily combining the two into a single unit.

[0025] The pressure frame displacement assembly or the fabric support plate displacement mechanism (usually the former depending on the design) moves the fabric-bag lip assembly below the sewing machine. The sewing machine starts and sews along the bag opening.

[0026] Compared with the prior art, this utility model provides an automated fabric bag opening machine, which has the following beneficial effects: This invention integrates laser cutting, automated hemming, bag lip positioning, and sewing into a single unit, achieving fully automated operation from fabric feeding to finished product sewing. Utilizing a pressure frame displacement component and a fabric support plate displacement mechanism, it enables automatic material flow between multiple workstations. Combined with the cyclical operation mode of two sets of fabric support plates, processes such as feeding, positioning, and sewing can be performed in parallel, completely eliminating waiting time between processes and resulting in an order-of-magnitude increase in production efficiency. Simultaneously, automated production completely eliminates reliance on skilled workers, ensuring extremely high consistency and stability in product quality.

[0027] 2. This utility model utilizes the precise coordination between the pressing frame assembly and the folding edge assembly. During the folding process, the pressing components (such as cylinders two and three) do not constantly press down on the fabric, but rather dynamically and locally release or lift the pressure according to the actions of the front and rear and left and right material-pulling components. Simultaneously, the assisted folding by the clamping components allows the material-pulling claws and plates to smoothly pull the fabric edge in and fold it, effectively avoiding the problems of uneven folding, wrinkling, or fabric damage caused by excessive friction in traditional methods. This ensures a clean, neat, and high-quality folding effect at the bag opening. Attached Figure Description

[0041] The movable cover plate includes cylinder nine 519, fixing bracket 520, cylinder ten 521, front cover plate 522, and rear cover plate 523. Four sets of fixing brackets 520 are fixedly connected to the upper side of the rectangular plate. A support plate is fixedly connected to the output end of the fixing bracket 520. Two sets of cylinder ten 521 are fixedly connected to the upper side of the support plate. One set of cylinder ten 521 is fixedly connected to the front cover plate 522, and the other set of cylinder ten 521 is fixedly connected to the rear cover plate 523.

[0042] The cylinder 521 of the movable cover plate retracts, and the cylinder 519 extends, pulling the front cover plate 522 and the rear cover plate 523 upward to open, making room for the folded edge.

[0043] The pressing frame assembly 4 descends via its lifting cylinder, bringing the pressing plate 41 and the pressed fabric close to the material-pulling mechanism of the folding assembly 5, but maintaining the pressed state.

[0044] The front and rear feeders are activated. Motor 1 51 drives pulley 2 54 and double-acting lead screw 55 to rotate via belt 1 52.

[0045] Two opposing threads on the bidirectional lead screw 55 drive two material-grabbing claws 56 to move toward each other along the motion track.

[0046] At the instant that the fabric-pulling claw 56 pulls the front and rear edges of the fabric inward, the pressing component responds in the corresponding area. For example, cylinder 2 42 or cylinder 3 44 may release or lift a small amount of pressure, allowing the fabric to bend and fold smoothly inward when pulled, rather than being pressed down. At the same time, cylinders 49 and 411 at clamping plates 1 and 2 are activated, pushing clamping plates 410 and 2 inward to fold the fabric. Then, cylinders 7 415 and 8 417 are activated, pushing upper positioning component 416 and lower positioning component 418 inward to press and flatten the folded fabric, ensuring a neat fold line. After the front and rear folds are completed, the front and rear fabric-pulling components reset.

[0047] The left and right material handling components are activated. First, motor 2 57 drives lead screw 1 58 to rotate, which in turn moves fixed plate 59 along guide rail 2 510, causing the entire left and right material handling mechanism to move to the working position.

[0048] Next, motor 513 starts, driving the lead screw to rotate, causing the two material feeders 512 to move towards each other on the fixed track.

[0049] Similarly, after the left and right material-ejecting plates 512 have finished ejecting the material, cylinder six 413 is activated. Cylinder six 413 drives the side plate positioning component 414, causing the side positioning block to move inward and fold the left and right fabric edges. At the same time, the pressing component coordinates and relaxes in the corresponding left and right areas. This fixes the completed front and rear folded parts, ensuring that the left and right folds are not disturbed. Two sets of clamping cylinders are fixedly connected to the back of the fixed platform, and the clamping cylinders correspond to the cloth support plate 3.

[0050] The lifting cylinder of the pressing frame assembly 4 drives the entire assembly downward, precisely pressing the fabric onto the bag lip of the support plate 3. At this time, the clamping cylinder on the back of the fixing table activates, clamping the support plate 3 below, temporarily combining the two into a single unit.

[0051] The pressure frame displacement assembly 7 or the fabric support plate displacement mechanism 8, depending on the design, is usually responsible for moving the "fabric-bag lip" assembly to below the sewing machine 6. The sewing machine 6 starts and sews along the bag opening.

[0052] The specific usage and function of this embodiment are as follows: Phase 1: Fixing the fabric and cutting the bag opening Fabric feeding: The operator lays the fabric to be opened flat on the pressure plate 41, so that it covers the rectangular groove area corresponding to the pressure strip 47 and the pressure strip 48.

[0053] Pressing the fabric: The pressing component is activated.

[0054] The piston rod of cylinder 42 retracts, driving the large pressure frame 46 to move downward.

[0055] The piston rod of cylinder 44 retracts, driving the small pressure frame 45 to move downward.

[0056] The large pressure frame 46 and the small pressure frame 45 respectively drive the pressure strip 47 and the pressure strip 48 fixed on their inner sides to pass through the rectangular groove on the pressure plate 41, firmly pressing the fabric onto the surface of the pressure plate 41. At this time, the fabric is completely fixed.

[0057] Transfer to the cutting position: The frame pressing displacement component 7 is activated, driving the entire frame pressing component 4 to move in the horizontal plane.

[0058] Motor 5 71 and Motor 6 76 work together. Motor 5 71 drives pulley 3 72 to rotate through pulley 1 and belt 3 73, and then drives track plate 1 711 to move in one direction, such as the X-axis, through a set of pulley 4 74 and belt 5 75.

[0059] Simultaneously, motor 6 76 drives pulley 6 78 and rectangular rotating rod 79 to rotate via pulley 2 and belt 6 77. Pulley 7 710, sliding on rectangular rotating rod 79, changes its radial position accordingly, driving the fixed platform to move along track plate 1 711 in another direction, such as the Y-axis, via the transmission belt.

[0060] The combined motion of the two causes the fixed platform and its connected pressure frame assembly 4 to move precisely to the underside of the laser cutter.

[0061] Laser cutting: A laser cutter emits a laser to cut a pre-set square shape, such as a bag opening, into the already compressed fabric.

[0062] Transfer to the folding position: After the cutting is completed, the frame pressing displacement component 7 moves again to precisely transfer the frame pressing component 4 above the folding component 5.

[0063] Phase Two: Dynamic Collaborative Automated Hemming This stage is the core of the equipment, requiring precise cooperation between the frame pressing assembly 4 and the folding assembly 5. The movable cover plate needs to be lowered and opened during this stage to allow space for the material unloading action.

[0064] Prepare to fold the edges and open the cover: The cylinder 521 of the movable cover plate retracts, and the cylinder 519 extends, pulling the front cover plate 522 and the rear cover plate 523 downwards and opening, making room for the folded edge.

[0065] The pressing frame assembly 4 is lowered by its lifting cylinder, so that the pressing plate 41 and the pressed fabric are close to the material feeding mechanism of the folding assembly 5, but remain in a pressed state.

[0066] Front and back folds and coordination: The front and rear feeder components are activated. Motor 1 51 drives pulley 2 54 and double-acting screw 55 to rotate via belt 1 52.

[0067] Two opposing threads on the bidirectional lead screw 55 drive two feeding claws 56 to move toward each other along the motion track.

[0068] At the instant that the fabric-pulling claw 56 pulls the front and rear edges of the fabric inward, the pressing component responds in the corresponding area. For example, cylinder 2 42 or cylinder 3 44 may release or lift a small amount of pressure, allowing the fabric to bend and fold smoothly inward when pulled, rather than being pressed down. At the same time, cylinders 49 and 411 at clamping plates 1 and 2 are activated, pushing clamping plates 410 and 2 inward to fold the fabric. Then, cylinders 7 415 and 8 417 are activated, pushing upper positioning component 416 and lower positioning component 418 inward to press and flatten the folded fabric, ensuring a neat fold line. After the front and rear folds are completed, the front and rear fabric-pulling components reset.

[0069] Left and right folding edges and coordination: The left and right material handling components are activated. First, motor 2 57 drives lead screw 1 58 to rotate, which in turn moves fixed plate 59 along guide rail 2 510, causing the entire left and right material handling mechanism to move to the working position.

[0070] Next, motor 513 starts, driving the lead screw to rotate, causing the two material feeders 512 to move towards each other on the fixed track.

[0071] Similarly, after the left and right material feeding plates 512 have finished feeding the material, cylinder six 413 is activated. Cylinder six 413 drives the side plate positioning component 414, causing the side positioning block to move inward, folding the left and right fabric edges. At the same time, the pressing component coordinates and relaxes in the corresponding left and right areas. This fixes the completed front and rear folded parts, ensuring that the left and right folds are not disturbed.

[0072] Folding and shaping, and closing the cover: Once all four sides are folded, the frame pressing assembly 4 lifts the fabric, and the movable cover plate resets and closes.

[0073] Phase 3: Bag Lip Preparation, Assembly, and Sewing Bag lip preparation: While the above steps are being performed in parallel, at another workstation, the operator places the bag lip on a set of idle support plates 3.

[0074] Bag lip positioning: Positioning mechanism 2 is activated. Rodless cylinder module 21 drives the mounting bracket to move into position, and then cylinder 22 pushes positioning plate 23 down along guide rail 24 to press or push the bag lip to the preset position, completing precise positioning.

[0075] Fabric support plate circulation and combination: The support plate displacement mechanism 8 moves the support plate 3, which has been positioned for the bag lip, to the assembly station.

[0076] Motor 7 81 drives the rotating shaft 83 to rotate via belt 7 82, and then drives the track plate 3 89 and the mechanism on it to move via belt 8 84.

[0077] Specifically, motor 85 drives belt 10 88 via belt 9 86 and pulley 87, causing the moving table 810 to slide along track plate 3 89. Cylinder 11 812 drives sliding plate 811 to move along linear guide rail, and cylinder 12 814 finally drives clamping rod 813 to clamp and move cloth support plate 3.

[0078] Meanwhile, the fabric that has been folded and pressed into shape by the movable cover plate is moved by the pressure frame displacement assembly 7 to the top of the same workstation.

[0079] The lifting cylinder of the pressing frame assembly 4 drives the entire assembly downward, precisely pressing the fabric onto the bag lip of the support plate 3. At this time, the clamping cylinder on the back of the fixing table activates, clamping the support plate 3 below, temporarily combining the two into a single unit.

[0080] Transfer and sewing: The presser frame displacement assembly 7 or the fabric support plate displacement mechanism 8, depending on the design, usually involves the former transferring the "fabric-bag lip" assembly to below the sewing machine 6. The sewing machine 6 starts and sews along the bag opening.

[0081] System Reset and Cycle: After sewing is completed, all clamping and holding mechanisms are released, and the finished product is removed. The empty fabric support plate 3 returns to station C to await the next feeding, while the pressing frame assembly 4 returns to station A to begin a new round of work. Through the alternating cycle of the two sets of fabric support plates 3, parallel operations of feeding, positioning, and sewing are achieved, forming a continuous and efficient production cycle.

[0082] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
