Description

Technical Field

[0001] The present invention relates to the technical field of garment processing, and more particularly to a pocket turning-up fixing mechanism and a pocket opening machine for opening pockets of garments. Background Art

[0002] In the garment manufacturing industry, pocket opening machines are essential auxiliary processing machinery, primarily used to create pockets in specific locations on garments to accommodate small items such as mobile phones and wallets. The traditional manufacturing process typically begins with a laser opening to create a stop, followed by a pocket opening machine to flanging and securing the pocket opening, and finally, sewing.

[0003] However, existing bag opening machines have many limitations in practical applications. Most of these machines are designed for pockets of specific sizes. When the pocket size changes, the machine has difficulty adapting and cannot complete precise flanging and fixing operations. In addition, the thickness of the clothing fabric is also a significant factor affecting the performance of the bag opening machine. Different garments use fabrics of varying thicknesses, and existing bag opening machines have poor adaptability to fabric thickness and are unable to automatically adjust the flanging and fixing parameters based on the fabric thickness. This results in poor flanging results, loose fixings, and even possible fabric damage when processing fabrics of varying thicknesses. This problem of poor compatibility with pocket size and fabric thickness has seriously affected the efficiency and quality of clothing production, increased production costs, and limited the ability of clothing companies to respond to demand for diversified products.

[0004] Therefore, how to solve the problem of poor compatibility of existing bag opening machines with respect to pocket size and fabric thickness is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide a pocket cuff fixing mechanism for opening a pocket in clothing, which is compatible with fabrics of different sizes and thicknesses within a certain size range.

[0006] Another object of the present invention is to provide a bag opening machine including the above-mentioned pocket flange fixing mechanism for opening pockets in clothing, which can quickly adapt to pockets of different sizes without replacing parts or making complicated equipment adjustments, thereby greatly shortening the changeover time and improving production efficiency.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0040] It should be noted that the directional words such as "upper" and "lower" below are defined based on the drawings in the specification.

[0041] The core of this invention is to provide a pocket cuff fixing mechanism for garment pocket openings that is compatible with fabrics of varying sizes and thicknesses within a certain size range. Another core aspect of this invention is to provide a pocket opening machine incorporating this pocket cuff fixing mechanism. This machine can quickly adapt to pockets of varying sizes and shapes without requiring component replacement or complex equipment adjustments, significantly reducing changeover time and improving production efficiency.

[0042] Please refer to Figure 1 and Figure 2 A pocket flanging fixing mechanism for opening a pocket in clothing includes a cloth pressing plate 1, a magnet 2 and a flanging fixing mechanism 3. The magnet 2 is arranged on the cloth pressing plate 1. The cloth pressing plate 1 presses the cloth to the flanging fixing mechanism 3 through the magnet 2. The coordinated use of the cloth pressing plate 1 and the magnet 2 provides a fast and reliable way to fix the cloth. The operator only needs to place the cloth on the flanging fixing mechanism 3 and then cover it with the cloth pressing plate 1. The magnet 2 can be automatically adsorbed and fixed without the need for additional fixing operations, which simplifies the cloth fixing process and improves work efficiency.

[0043] The flange fixing mechanism 3 includes a base plate 31, a first flange fixing component 32, a second flange fixing component 33, a limiting pressure plate 34 and an elastic member 35. Specifically, the first flange fixing component 32 is symmetrically arranged at the two short side ends of the base plate 31, and the first flange fixing component 32 is movable along the length direction of the base plate 31, so that the mechanism can adapt to the size changes of the pocket in the long side direction. The second flange fixing component 33 is symmetrically arranged at the two long side ends of the base plate 31, and the second flange fixing component 33 is movable along the width direction of the base plate 31, so that the mechanism can adapt to the size changes of the pocket in the short side direction. The movable design of the first flange fixing component 32 and the second flange fixing component 33 enables the first flange fixing component 32 and the second flange fixing component 33 to be flexibly adjusted according to the actual size of the pocket, so that they can quickly adapt to pockets of different sizes.

[0044] The limiting pressure plate 34 is connected to the base plate 31, and an elastic member 35 is provided between the limiting pressure plate 34 and the first flanging fixing component 32 and the second flanging fixing component 33. The elastic member 35 is used to limit the movement of the first flanging fixing component 32 and the second flanging fixing component 33 in the vertical direction. The elastic member 35 provided between the limiting pressure plate 34 and the first flanging fixing component 32 and the second flanging fixing component 33 provides the mechanism with an adjustable elastic pressing force, so that the mechanism can adapt to fabrics of different thicknesses. Whether it is thin fabric or thick fabric, the elastic member 35 can automatically adjust the pressing force according to the thickness of the fabric, ensuring that the fabric will not be damaged due to excessive pressing force or shifted due to insufficient pressing force during the flanging and fixing process, thereby improving the compatibility of the mechanism with different fabric thicknesses.

[0045] The first and second flange fixing assemblies 32, 33 are each provided in two sets, symmetrically arranged. The symmetrical arrangement of the first and second flange fixing assemblies 32, 33 ensures balanced force during operation. When flanging and fixing the short and long sides of a pocket, the assemblies on both sides are simultaneously stressed, avoiding imbalance or deformation of the equipment caused by unilateral force. This enhances the stability and reliability of the equipment during operation and extends its service life. This balanced force distribution also helps reduce vibration during operation, ensuring that the equipment can stably and accurately complete the flanging and fixing of the pocket, further improving the quality and stability of the product.

[0046] It should be noted that the limiting pressure plate 34 is fixed to the bottom plate 31 by screws or welding to limit the vertical movement of the first flange fixing assembly 32 and the second flange fixing assembly 33 .

[0047] The overall mechanism is compact in design and the layout of the components is reasonable, making full use of the limited space, so that the volume of the entire flange fixing mechanism 3 is relatively small. For clothing processing workshops, this means that more equipment can be arranged in a limited production space, improving space utilization and facilitating equipment maintenance and management.

[0048] The pocket flap fixing mechanism for opening pockets in clothing arranged in the above manner is compatible with fabrics of various sizes and thicknesses, eliminating the need for frequent replacement of equipment or parts due to changes in pocket size or fabric thickness, thereby reducing equipment replacement costs and time costs.

[0049] In the above embodiment, the bottom plate 31 is provided with a first guide groove 311 for limiting the moving direction of the first flange fixing assembly 32 , and a second guide groove 312 for limiting the moving direction of the second flange fixing assembly 33 .

[0050] It should be noted that the base plate 31 is provided with guide grooves around its perimeter, along which the first and second flange fixing assemblies 32, 33 can slide. The first and second guide grooves 311, 312 provide a clear path for the first and second flange fixing assemblies 32, 33 to move, ensuring the precision and stability of these two assemblies during movement. This ensures that the flange fixing assemblies are accurately positioned in the desired position, enabling precise flanging and securing of the short and long sides of the pocket, and improving the stability and consistency of the flanging quality.

[0051] The guide groove design effectively reduces lateral deviation and shaking of the flange fixing assembly during movement. Through precise guidance, each flange fixing operation is ensured to be performed along the predetermined path, significantly reducing the defective rate during production. The first guide groove 311 and the second guide groove 312 provide stable support for the flange fixing assembly, ensuring that the assembly remains stable during movement.

[0052] Furthermore, the design of the guide groove enables the first flange fixing component 32 and the second flange fixing component 33 to be compactly arranged on the base plate 31, making full use of the space of the base plate 31, improving the space utilization rate of the equipment, and making the overall size of the equipment more compact, which is convenient for integration into existing clothing processing production lines. There is no need for large-scale transformation and adjustment of the production site, thereby reducing the installation and use costs of the equipment.

[0053] Please refer to Figure 3 The first flange fixing assembly 32 includes a first tongue plate 321, a first pressure plate 322 and a first slide plate 323 stacked in sequence. The first slide plate 323 is slidably arranged along the first guide groove 311. The first slide plate 323 is provided with a first slide groove. The first tongue plate 321 and the first pressure plate 322 are both slidably arranged along the first slide groove. The clamping end of the first pressure plate 322 is provided with an opening.

[0054] As will be understood, the first slide plate 323 has a first internal slot, along which the first tongue plate 321 and the first pressure plate 322 can slide. The first tongue plate 321 is positioned above the first pressure plate 322, allowing for relative sliding movement. Both slide plates have connecting holes and slotted sliding holes for access by a drive mechanism, which drives the first tongue plate 321 and the first pressure plate 322. Both the first tongue plate 321 and the first pressure plate 322 slide along the first slot, allowing the operator to flexibly adjust their positions based on the fabric thickness and flanging requirements. This flexible adjustment capability accommodates fabrics of varying thicknesses and materials, enhancing the versatility and adaptability of the device.

[0055] The stacked design of the first tongue plate 321, the first pressure plate 322, and the first slide plate 323 allows the flanging operation to be performed in layers. The first tongue plate 321 is responsible for the initial positioning and guidance of the fabric flanging, while the first pressure plate 322 compresses and secures the fabric after flanging. This layered design ensures the accuracy and stability of the flanging operation, avoiding the uneven or uneven flanging caused by the operation of a single component. The first pressure plate 322 has an opening at the pressing end, allowing it to better adapt to fabrics of varying thicknesses and provide a stable holding force during the pressing process.

[0056] The flexible adjustment capabilities of the first tongue plate 321 and the first pressure plate 322 enable the device to quickly adapt to pockets of varying sizes and shapes without having to replace parts or make complex equipment adjustments. This rapid changeover capability significantly reduces changeover time and improves production efficiency. It is particularly suitable for small-batch, high-variety garment production, enabling rapid response to market changes and customer needs.

[0057] Furthermore, first ball plungers 324 are provided on both side walls of the first chute, and guide blocks are provided on the first tongue plate 321 and the first pressure plate 322 . The guide blocks are provided with slots for engaging with the first ball plungers 324 .

[0058] It should be noted that after the first ball plunger 324 is engaged with the slots of the first tongue plate 321 and the first pressure plate 322, the first tongue plate 321 and the first pressure plate 322 cannot slide on their own and require a certain force to achieve sliding. In the initial position, the first ball plunger 324 is in the slots of the first tongue plate 321 and the first pressure plate 322. Specifically, the guide blocks on the first tongue plate 321 and the first pressure plate 322 cooperate with the first guide grooves to ensure the positional accuracy of the first tongue plate 321 and the first pressure plate 322 during the sliding process. The first ball plunger 324 is engaged with the slots on the guide blocks, so that the first tongue plate 321 and the first pressure plate 322 can accurately return to the initial position or other preset position after each movement, thereby improving the stability and consistency of the flanging operation.

[0059] In the above embodiment, the first slide plate 323 is provided with at least two set screws for fixing the first slide plate 323 to the first guide slot 311. The set screws may also be installed on both sides of the first guide slot 311 to fix the first slide plate 323 to the first guide slot 311.

[0060] It is understood that the set screws are mounted on the first slide plate 323. When the set screws are tightened downward, the first slide plate 323 is fixed, and the bottom end of the set screws abuts against the first guide groove 311 of the base plate 31, thereby securing the first slide plate 323 to the base plate 31 and preventing the first slide plate 323 from sliding within the first guide groove 311 of the base plate 31. Securing the first slide plate 323 within the first guide groove 311 by at least two set screws ensures that the first slide plate 323 remains stable during operation and is prevented from displacement due to external forces or vibrations. This allows the first flanging fixing assembly 32 to maintain a precise position during the flanging and fixing operations, thereby improving the stability and consistency of the flanging quality.

[0061] The use of set screws allows the operator to precisely adjust the position of the first slide 323. During adjustment, the operator can first loosen the set screw, move the first slide 323 to the desired position, and then tighten the set screw to secure it. This precise adjustment capability ensures that the first slide 323 is accurately positioned in the desired position during each operation, improving the processing accuracy of the equipment. The set screw design makes the equipment operation more intuitive and simple. The operator does not need to make complex adjustments or use additional tools; simply tightening or loosening the screw can complete the fixing and release of the first slide 323. This reduces the number of steps and time required, reduces the difficulty of operation, and improves the versatility and ease of use of the equipment.

[0062] Please refer to Figure 4 The second flange fixing assembly 33 includes a second tongue plate 331, a second pressure plate 332 and a second slide plate 333 stacked in sequence. The second slide plate 333 is slidably arranged along the second guide groove 312. The second slide plate 333 is provided with a second slide groove. The second tongue plate 331 and the second pressure plate 332 are both slidably arranged along the second slide groove. The clamping end of the second pressure plate 332 is provided with an opening.

[0063] It should be noted that the second slide plate 333 has a second internal chute, along which the second tongue plate 331 and the second pressure plate 332 can slide. The second tongue plate 331 slides relative to the second pressure plate 332. Both slide plates have connecting holes and slotted sliding holes for access to the drive mechanism, which drives the second tongue plate 331 and the second pressure plate 332. The second tongue plate 331 and the second pressure plate 332 slide along the second chute, allowing the operator to flexibly adjust their positions based on the fabric thickness and flanging requirements. This flexible adjustment capability accommodates fabrics of varying thicknesses and materials, enhancing the versatility and adaptability of the device.

[0064] The stacked design of the second tongue plate 331, second pressure plate 332, and second slide plate 333 allows the flanging operation to be performed in layers. The second tongue plate 331 is responsible for the initial positioning and guidance of the fabric flanging, while the second pressure plate 332 compresses and secures the fabric after flanging. This layered design ensures the accuracy and stability of the flanging operation, avoiding the uneven or uneven flanging caused by the operation of a single component. The second pressure plate 332 has an opening at the pressing end, allowing it to better adapt to fabrics of varying thicknesses and provide stable holding force during the pressing process.

[0065] The flexible adjustment capabilities of the second tongue plate 331 and the second pressure plate 332 enable the machine to quickly adapt to pockets of varying sizes and shapes without having to replace parts or make complex equipment adjustments. This rapid changeover capability significantly reduces changeover time and improves production efficiency. It is particularly suitable for small-batch, high-variety garment production, enabling rapid response to market changes and customer needs.

[0066] In the above embodiment, the second ball plunger 334 is provided on both side walls of the second slide groove, and the second tongue plate 331 and the second pressure plate 332 are both provided with guide blocks, and the guide blocks are provided with a slot for engaging with the second ball plunger 334 .

[0067] It is understandable that after the second ball plunger 334 is engaged with the slots of the second tongue plate 331 and the second pressure plate 332, the second tongue plate 331 and the second pressure plate 332 cannot slide on their own and require a certain amount of force to achieve sliding. In the initial position, the second ball plunger 334 is in the slots of the second tongue plate 331 and the second pressure plate 332. Specifically, the guide blocks on the second tongue plate 331 and the second pressure plate 332 cooperate with the second guide grooves to ensure the position accuracy of the second tongue plate 331 and the second pressure plate 332 during the sliding process. The second ball plunger 334 is engaged with the slots on the guide blocks, so that the second tongue plate 331 and the second pressure plate 332 can accurately return to the initial position or other preset positions after each movement, thereby improving the stability and consistency of the flanging operation.

[0068] As a preferred embodiment, the second slide plate 333 is provided with at least two set screws, which are used to fix the second slide plate 333 to the second guide groove 312. The set screws can also be installed on both sides of the second guide groove 312 to fix the second slide plate 333 to the second guide groove 312.

[0069] It should be noted that the set screw is mounted on the second slide plate 333. When the set screw is tightened downward, the second slide plate 333 is fixed, and the bottom end of the set screw abuts against the second guide groove 312 of the base plate 31, thereby fixing the second slide plate 333 to the base plate 31 and preventing the second slide plate 333 from sliding within the second guide groove 312 of the base plate 31. Securing the second slide plate 333 within the second guide groove 312 by at least two set screws ensures that the second slide plate 333 remains stable during operation and is not displaced by external forces or vibrations. This allows the second flanging fixing assembly 33 to maintain a precise position during the flanging and fixing operations, thereby improving the stability and consistency of the flanging quality.

[0070] The use of set screws allows the operator to precisely adjust the position of the second slide 333. During adjustment, the operator can first loosen the set screw, move the second slide 333 to the desired position, and then tighten the set screw to secure it. This precise adjustment capability ensures that the second slide 333 is accurately positioned in each operation, improving the processing accuracy of the equipment. The set screw design makes the equipment operation more intuitive and simple. The operator does not need to make complex adjustments or use additional tools. Simply tightening or loosening the screw can complete the fixing and release of the second slide 333, reducing the number of steps and time, reducing the difficulty of operation, and improving the versatility and ease of use of the equipment.

[0071] In the above case, the elastic member 35 is an elastic plate, and the elastic plate is provided on the first tongue plate 321 and the second tongue plate 331 .

[0072] As can be understood, the elastic plate presses the first and second tongue plates 321 and 331 downward, while also allowing for a certain amount of vertical flexibility, allowing for compatibility with a range of fabric thicknesses. The elastic properties of the elastic plate allow the first and second tongue plates 321 and 331 to accommodate fabrics of varying thicknesses. During the flanging process, the elastic plate automatically adjusts the pressing force based on the fabric thickness, ensuring that the fabric is neither damaged by excessive pressure nor displaced by insufficient pressure. This design significantly improves the mechanism's adaptability to fabrics of varying thicknesses, making it particularly suitable for garments requiring a wide range of fabric thicknesses. The elastic properties of the elastic plate also provide a stable securing mechanism. During the flanging and securing process, the elastic plate automatically adapts to slight deformations or positional changes in the fabric, maintaining a stable holding position and preventing the fabric from shifting or loosening during the flanging and securing process. This ensures smoother subsequent sewing processes and reduces the rate of defective products resulting from insecure fabric fixation. The elastic plate's flexibility allows it to accommodate fabrics of varying materials. For soft or easily deformable fabrics, the elastic plate provides gentle yet stable pressure, preventing deformation or damage caused by rigid pressure. For stiffer fabrics, the elastic plate also provides sufficient pressure to ensure stability, thereby improving the mechanism's adaptability to different fabric materials. The elastic plate's design eliminates the need for complex adjustments when flanging and securing fabric. The elastic plate automatically adapts to the thickness and material of the fabric. Operators simply position the fabric in the appropriate position, and the plate automatically provides the appropriate pressure, streamlining the process and improving efficiency.

[0073] The elastic plate ensures that the first tongue plate 321 and the second tongue plate 331 exert a uniform vertical pressure. This uniform pressure helps to achieve a smooth turning edge of the pocket seam, avoiding problems such as uneven turning edges caused by uneven pressure, thereby improving the appearance and sewing quality of the pocket.

[0074] In practical applications, the elastic plate may be a spring, a spring plate, or elastic rubber, etc., and there is no limitation to this.

[0075] Furthermore, the first tongue plate 321 and the first pressure plate 322 are vertically staggered with the second tongue plate 331 and the second pressure plate 332 to avoid interference during movement. This ensures that the first and second flange fixing assemblies 32, 33 can independently perform flange operations, avoiding interference caused by spatial overlap between components and improving the smoothness and reliability of the device's operation. Because the first and second flange fixing assemblies 32, 33 can move independently and without interfering with each other, the device can operate on both the short and long sides of a pocket simultaneously, eliminating the need to wait for one assembly to complete before operating another. This significantly improves flange efficiency, shortens production cycles, and increases production efficiency.

[0076] It should be noted that the staggered design enables the first flanging fixing assembly 32 and the second flanging fixing assembly 33 to be efficiently arranged within a limited space, thereby improving the space utilization of the equipment, reducing the overall size and floor space of the equipment, and making the structure of the equipment clearer and simpler, making it easier for operators to operate and maintain. The staggered design rationally divides the working areas of the first flanging fixing assembly 32 and the second flanging fixing assembly 33, allowing the various components to cooperate and work together to form an organic whole. This reasonable partitioning not only improves the working efficiency of the equipment, but also makes the structure of the equipment clearer and simpler, making it easier for operators to operate and maintain, and also facilitates design and production by equipment manufacturers. The staggered design ensures that the first flanging fixing assembly 32 and the second flanging fixing assembly 33 can maintain precise position and motion trajectory during movement, which helps to improve the accuracy and quality of the flanging, ensuring that both the short and long sides of the pocket can achieve a uniform and smooth flanging effect, thereby improving the appearance quality and sewing quality of the product.

[0077] Please refer to Figure 5 In a feasible embodiment, the flange fixing mechanism 3 includes a base plate 31, a first flange fixing component 32, a second flange fixing component 33, a locking block 6, a gear 5, a rack 4, a pad, and a cover plate. The first flange fixing component 32 and the second flange fixing component 33 are provided with racks 4 on both sides, which mesh with the gear 5. The gear 5 can rotate around their respective locking screws. When the locking screws are tightened, the locking block 6 is pulled upward, and the gear 5 is clamped between the locking block 6 and the pad and cannot rotate, thereby fixing the first flange fixing component 32 and the second flange fixing component 33. When the position of the flange fixing component needs to be adjusted, by rotating the gear 5, the meshing relationship between the gear 5 and the rack 4 enables the flange fixing component to be moved to the desired position along the guide groove of the base plate 31. The transmission principle of the gear 5 and the rack 4 is used to achieve precise position adjustment, ensuring that the flange fixing mechanism 3 can adapt to pockets of different sizes.

[0078] The locking block 6 is not fixed to the base plate 31. When the locking screw is tightened, the locking block 6 is pulled upward, and the gear 5 is clamped between the locking block 6 and the backing plate. Due to the tensioning effect of the locking block 6, the gear 5 cannot rotate on the rack 4, thereby achieving the fixation of the first flange fixing assembly 32 and the second flange fixing assembly 33. When the position of the flange fixing mechanism 3 needs to be adjusted, the locking screw is loosened, the locking block 6 is relaxed, and the gear 5 resumes its free rotation state. The position of the flange fixing mechanism 3 can be adjusted again by rotating the gear 5. The position of the flange fixing mechanism 3 can be adjusted by simply rotating the gear 5, which can adapt to pockets of different sizes and improve the versatility and flexibility of the device.

[0079] In summary, the pocket flange fixing mechanism for opening pockets in clothing provided by the present invention is used by manually loosening the fixing screws on the first slide 323 and the second slide 333, moving the first slide 323 and the second slide 333 in the guide groove of the base plate 31 until they reach a position that meets the pocket size to be produced, manually tightening the fixing screws of the first slide 323 and the second slide 333 respectively to fix the first slide 323 and the second slide 333, then placing the fabric on the flange fixing mechanism 3, covering the fabric pressing plate 1, and the magnet 2 on the fabric pressing plate 1 is adsorbed on the flange fixing mechanism 3 to fix the fabric. The driving device drives the first tongue plate 321 on one side to extend and reach the folding position of the pocket stop, then drives the first pressing plate 322 to extend, causing the pocket stop to enter the opening on the first pressing plate 322. The first pressing plate 322 then retracts back to its original position, driving the stop to bend along the first tongue plate 321. The first tongue plate 321 then retracts back to its original position, leaving a sewing area. The first tongue plate 321 and the first pressing plate 322 on the other side then perform the same action to flanging the stop on the other side. After the stop is flanging, the second tongue plate 331 extends and reaches the folding position of the pocket stop. The second pressing plate 332 then extends and causes the pocket stop to enter the opening on the second pressing plate 332. The second pressing plate 332 then retracts back to its original position, driving the stop to bend along the second tongue plate 331. The second tongue plate 331 then retracts back to its original position, leaving a sewing area. After the flaps around the pocket are completed, the first ball plunger 324 is inserted into the slots of the first tongue plate 321 and the first pressure plate 322, and the second ball plunger 334 is inserted into the slots of the second tongue plate 331 and the second pressure plate 332, thereby fixing the pocket flaps for the next sewing operation.

[0080] Compared with the existing technology, this mechanism has a compact structure and can save equipment space. At the same time, it can be infinitely compatible with fabrics of different lengths, widths and thicknesses within a certain size range, realizing rapid changeover production.
