Abstract
Description
Technical Field
[0001] This invention relates to the field of textile technology, and in particular to a sewing system and sewing equipment. Background Technology
[0002] In the existing sewing processing fields of clothing, bags, and footwear, double-needle sewing machines are widely used as an important production equipment. In current double-needle machine technology, the fabric feeding process mainly relies on manual operation. The operator needs to manually place the fabric under the presser foot and continuously guide and push the fabric during the sewing process to ensure it moves smoothly along the predetermined path.
[0003] However, this manual sewing method has significant drawbacks. Operators need to manually align the various materials to be sewn, and due to changes in sewing position, they must continuously search for the corresponding sewing location. This is detrimental to sewing accuracy; for example, when the spacing between the materials is uneven or the tightness of the fit is inconsistent, the stitches are prone to asymmetry. Furthermore, manual sewing cannot maintain stable tension for extended periods. The fabric is prone to wrinkling, stretching, and even springing back during continuous pushing, resulting in skipped stitches, misaligned stitches, and dimensional deviations, severely impacting the quality of the finished product. Summary of the Invention
[0004] The main objective of this invention is to provide a sewing system and sewing equipment that can improve sewing efficiency, stability, and automation.
[0005] To achieve the above objectives, some embodiments of the present invention provide a sewing system comprising: frame, The loading platform connects to the frame and is suitable for carrying the first material. The pressing structure is connected to the frame and is located above the loading platform. The pressing structure is suitable for bonding the first material. The pressing structure has a vertical through hole through itself, through which the needle assembly passes to facilitate sewing the first material and other materials. The needle assembly is connected to the frame, and the end of the needle assembly is configured to have an extended position and an end position. In the extended position, the needle assembly is adapted to sew a first material and other materials. In the end position, the needle assembly is adapted to be spaced apart from the first material and other materials respectively. The end position is located on one side of the extended position along a first direction. The needle assembly switches from the extended position to the end position to sew the first material and other materials and drives the first material and other materials to move along the first direction.
[0006] In some embodiments, the sewing system further includes an auxiliary wheel set, which includes a roller and a wheel set bracket. The wheel set bracket is connected to the frame, and the roller is rotatably connected to the wheel set bracket. The roller is capable of rotating in a direction perpendicular to the first direction, and the outer peripheral wall of the roller is adapted to abut against the first material.
[0007] In some embodiments, the wheel set support includes a first segment and a second segment. The first segment has two ends that are distributed opposite to each other along the length direction. A roller is rotatably connected to one end of the first segment, and the other end of the first segment is rotatably connected to the second segment. The rotation axes of the first segment and the second segment are parallel to the rotation axis of the roller.
[0008] In some embodiments, the sewing system further includes a cutter assembly connected to the frame, the cutter assembly being disposed on one side of the needle assembly along a first direction, and the cutter assembly being configured to cut the sewn first material and other materials so as to separate the sewn first material and other materials from each other.
[0009] In some embodiments, the sewing system further includes a material collection assembly, which includes at least a material guide groove disposed on one side of the cutting blade assembly along a first direction and inclined downward to guide the first material and other materials separated by the cutting blade assembly.
[0010] In some embodiments, the sewing system further includes a pull tube structure disposed below the carrying platform. The pull tube structure includes an upper side and a lower side distributed in a vertical direction. The upper side is adapted to pass through a first material, and the lower side is adapted to pass through other materials. A needle assembly is disposed at one end of the pull tube structure facing a first direction to be adapted to sew the first material and other materials passing through the pull tube structure.
[0011] In some embodiments, the pull tube structure includes a first outer wall and a second outer wall protruding in a vertical direction. The first outer wall and the second outer wall are disposed on opposite sides of the pull tube structure along a second direction. The first direction, the second direction and the vertical direction are perpendicular to each other. The outer surfaces of the first outer wall and the second outer wall are both suitable for attaching other materials.
[0012] A second aspect of the present invention provides a sewing device for sewing a front panel of a hat and a binding strip. The front panel includes a hat body, a first piece, and a second piece, both connected to the same edge of the hat body. The sewing device comprises the sewing system of any one of claims 1 to 7. The sewing device includes a pull tube structure, a connecting frame, and a guide member and a separating member. The separating member is located on the side of the guide member facing a first direction. The guide member defines a first guide channel, which is adapted to allow the first and second pieces to pass through together. The separating member is adapted to separate the first and second pieces passing through the first channel, such that the first and second pieces are spaced apart along a second direction, which is perpendicular to the second direction. The outer wall of the pull tube structure is adapted to fit the binding strip, which connects the first and second pieces separated by the separating member to opposite sides of the hat body along the second direction.
[0013] In some embodiments, the sewing device further includes an auxiliary structure, which includes a first support foot and a second support foot spaced apart along a second direction. Both the first support foot and the second support foot are adapted to extend into the inside of the hat body to assist the pressing structure in fitting the inside of the hat body.
[0014] In some embodiments, the sewing device further includes a feeding structure comprising grippers and a rotating base, the grippers being adapted to grip the front panel of the cap and the rotating base being rotatably connected to the grippers to adjust the orientation of the front panel of the cap.
[0015] According to the above embodiments, the beneficial effects of the present invention are: The sewing system of this application includes a frame, a carrying platform, a pressing structure, and a needle assembly. The frame serves as the structural foundation of the entire system and is used to connect other accessories. The carrying platform is connected to the frame and is adapted to carry a first material, which may be a material such as a hat body front panel. The pressing structure is connected to the frame and is located above the carrying platform. The pressing structure is adapted to fit the first material and has a vertical through-hole through which the needle assembly passes to sew the first material and other materials. The needle assembly is connected to the frame, and its end is configured with an extended position and a terminated position. In the extended position, the needle assembly is adapted to sew the first material and other materials. In the terminated position, the needle assembly is adapted to be spaced apart from the first material and other materials respectively. The terminated position is located on one side of the extended position along a first direction. The needle assembly switches from the extended position to the terminated position to sew the first material and other materials and at least drives the first material to move along the first direction.
[0016] In summary, by integrating the sewing action of the needle assembly with the material driving function, the sewing system automatically propels the first material along a first direction during the sewing process, enabling the sewing action to proceed spontaneously and continuously, thus improving sewing efficiency. After completing the sewing at the extended position, the movement trajectory of the needle assembly's end point during its movement to the end position can be considered a fan shape. This not only completes the sewing action but also drives the first material forward synchronously through its trajectory change, avoiding the complex structure of an additional feeding mechanism required in traditional sewing. This design simplifies equipment composition, reduces manufacturing costs, and simultaneously improves the system's compactness and operational stability.
[0017] The pressing structure provides appropriate adhesion pressure to the first material during sewing; that is, the pressure provided by the pressing structure is less than the traction force exerted by the needle assembly to move the first material along the first direction. The pressing structure restricts the vertical movement of the material, ensuring stable material position during sewing and improving the uniformity and consistency of the stitches. Due to the through-hole design of the pressing structure, the needle assembly can accurately pass through and complete the sew, avoiding skipped stitches or uneven stitches caused by material misalignment. The overall structure achieves simultaneous sewing and feeding, improving automation while ensuring sewing quality, making it suitable for continuous, high-efficiency production needs.

[0026] The following is for reference. Figures 1 to 14 This describes a sewing system and sewing equipment according to embodiments of the present invention. (Refer to...) Figures 1 to 4 In some embodiments, the sewing system of this application includes a frame 100, a carrying platform 400, a pressing structure 1000, and a needle assembly 900. The frame 100 serves as the structural foundation of the entire system and is used to connect other accessories. The carrying platform 400 is connected to the frame 100 and is adapted to carry a first material, which may be a material such as the front panel 20 of a cap. The pressing structure 1000 is connected to the frame 100 and is located above the carrying platform 400. The pressing structure 1000 is adapted to conform to the first material and has a vertical through-hole 1100 through which the needle assembly 900 passes to facilitate sewing the first material and other materials. The needle assembly 900 is connected to the frame 100. The end of the needle assembly 900 is configured to have an extended position and an end position. In the extended position, the needle assembly 900 is adapted to sew a first material and other materials. In the end position, the needle assembly 900 is adapted to be spaced apart from the first material and other materials respectively. The end position is located on one side of the extended position along a first direction. The needle assembly 900 switches from the extended position to the end position to sew the first material and other materials and drives the first material and other materials to move along the first direction.
[0027] In summary, by integrating the sewing action of the needle assembly 900 with the material driving function, the sewing system achieves automatic propulsion of the first material along a first direction during the sewing process, enabling the sewing action to proceed spontaneously and continuously, thus improving sewing efficiency. After completing the sewing at the extended position, the movement trajectory of the needle assembly 900's end as it moves to the end position can be considered a fan shape. This not only completes the sewing action but also drives the first material forward synchronously through its trajectory change, avoiding the complex structure of an additional feeding mechanism required in traditional sewing. This design simplifies the equipment composition, reduces manufacturing costs, and simultaneously improves the system's compactness and operational stability.
[0028] The pressing structure 1000 provides appropriate bonding pressure to the first material during sewing; that is, the pressure provided by the pressing structure 1000 is less than the traction force exerted by the needle assembly 900 to move the first material along the first direction. The pressing structure 1000 restricts the vertical movement of the material, ensuring stable material position during sewing and improving the uniformity and consistency of the stitches. Due to the through-hole 1100 design of the pressing structure 1000, the needle assembly 900 can accurately pass through and complete the sewing, avoiding skipped stitches or uneven stitches caused by material misalignment. The overall structure achieves simultaneous sewing and feeding, improving automation while ensuring sewing quality, making it suitable for continuous, high-efficiency production needs.
[0029] In some embodiments, the through hole 1100 of the pressing structure 1000 is a strip hole extending along the first direction. This design facilitates the fan-shaped movement of the needle and provides ample room for the needle to pull the first material along the first direction.
[0030] Reference Figures 3 to 7In some embodiments, the sewing system further includes an auxiliary wheel assembly 2000, which includes a roller 2100 and a wheel assembly bracket 2200. The wheel assembly bracket 2200 is connected to the frame 100, and the roller 2100 is rotatably connected to the wheel assembly bracket 2200. The roller 2100 can rotate in a direction perpendicular to the first direction, and the outer peripheral wall of the roller 2100 is adapted to abut against the first material. During the sewing process, the auxiliary wheel assembly 2000 provides limiting support to the first material at a different position than the pressing structure 1000. The outer peripheral wall of the roller 2100 rolls in contact with the surface of the material, which not only limits the material's displacement in the direction perpendicular to the first direction but also avoids scratches or stretching deformation of the fabric caused by sliding friction. The roller 2100 rotates freely around an axis perpendicular to the first direction and can roll synchronously with the advancement of the first material, so that the constraint on the first material is always gentle and continuous, and the first material will not wrinkle or get stuck due to sudden changes in local resistance. The wheel set bracket 2200 confines the roller 2100 at a height position that applies appropriate pressure to the first material, ensuring a mutually corresponding limiting relationship between it and the pressing structure 1000. The material obtains a stable trajectory between them, maintaining straight-line movement even during high-speed sewing, improving stitch straightness and appearance consistency. This auxiliary wheel set 2000 has a simple structure, occupies little space, requires no additional power, and achieves dynamic limiting solely through the movement of the material itself. While improving sewing quality, it reduces equipment complexity and energy consumption, providing a reliable guarantee for long-term continuous production.
[0031] Reference Figures 3 to 7 In some embodiments, the wheel assembly bracket 2200 includes a first segment 2210 and a second segment 2220. The first segment 2210 has two ends that are relatively distributed along its length. A roller 2100 is rotatably connected to one end of the first segment 2210, and the other end of the first segment 2210 is rotatably connected to the second segment 2220. The rotation axes of the first segment 2210 and the second segment 2220 are parallel to the rotation axis of the roller 2100. The wheel assembly bracket 2200 includes a first segment 2210 and a second segment 2220, with a rotating joint between them that is parallel to the axis of the roller 2100, allowing the roller 2100 to achieve adaptive swing freedom while maintaining its limiting function. When the first material momentarily rises or falls due to changes in thickness or local unevenness, the first segment 2210 can rotate slightly around the rotation axis, causing the roller 2100 to float up and down as a whole, instantly releasing excess pressure and avoiding fabric indentations, stretching, or even machine stoppage caused by rigid compression. In some embodiments, the rotating joint incorporates built-in damping to absorb vibration and reduce rebound, preventing continuous wobbling of the roller 2100 after floating and ensuring that the limiting action is always gentle and stable. This segmented support design achieves pressure adaptation and vibration suppression with a simple mechanical structure, improving the smoothness of material passage and reducing the frequency of maintenance due to jamming, providing continuous and reliable protection for high-speed, continuous sewing.
[0032] Referring to 3, in some embodiments, the sewing system further includes a cutter assembly 800 connected to the frame 100, the cutter assembly 800 being disposed on one side of the needle assembly 900 along a first direction, and the cutter assembly 800 being configured to cut the sewn first material and other materials so that the sewn first material and other materials are separated from each other.
[0033] The cutting blade assembly 800 is integrated into the frame 100 and located downstream of the needle assembly 900, enabling continuous sewing and cutting. When the needle assembly 900 completes sewing and continues to drive the material along the first direction, the sewn edge of the material is immediately guided into the working area of the cutting blade assembly 800 for immediate cutting. This layout eliminates the traditional secondary positioning, transfer, or manual trimming steps, completely eliminating dimensional drift caused by repeated clamping, ensuring that the cut and the final stitch always maintain a fixed relative position, resulting in neat thread ends and a consistent appearance. Simultaneously, continuous cutting avoids material buildup and blockage, keeping the work area clean and reducing downtime for cleaning. The blade assembly shares the same feeding power as the sewing action, requiring no additional drive. Its compact structure and low energy consumption improve overall machine integration and shorten the single-piece processing cycle, providing subsequent processes with clean-edged, dimensionally stable semi-finished products, effectively balancing efficiency and quality. For example, if the first direction is horizontal, the blades of the cutting blade assembly 800 move vertically. When the cutting node of the entire unit consisting of the first sewn material and other materials reaches the blade position, the cutting blade assembly 800 performs the cutting. Since the transport speed, sewing length, and incoming material length can all be preset, the cutting node can be accurately calculated, resulting in a high degree of automation in the sewing system.
[0034] Reference Figure 3 In some embodiments, the sewing system further includes a material collection assembly 3000, which includes at least a guide trough located on one side of the cutting blade assembly 800 along a first direction and inclined downwards to guide the material being cut by the cutting blade assembly 800. The inclined design of the guide trough provides a material discharge path for the cutting blade assembly 800. The cut material automatically slides down the guide trough under gravity, quickly detaching from the sewing area, preventing material accumulation that could cause jamming or contamination of subsequent fabric, keeping the work surface clean. The inclined channel eliminates the need for additional fans or conveyor belts, simplifying the structure and eliminating the risk of downtime due to material entanglement. The guide trough and the cutting blade assembly 800 are arranged sequentially along the first direction, ensuring that the cutting and discharge actions are completed continuously, preventing material from springing back into the sewing area and affecting stitch quality. This material collection solution achieves continuous and reliable material management at low cost, provides a clean and safe production environment for long-term unattended operation, and effectively improves the smoothness of overall machine operation and ease of maintenance.
[0035] Reference Figures 8 to 12 In some embodiments, the sewing system further includes a pull tube structure 300, located below the loading platform 400. The pull tube structure 300 includes an upper side and a lower side distributed vertically. The upper side is suitable for passing through a first material, and the lower side is suitable for passing through other materials. A needle assembly 900 is located at the end of the pull tube structure 300 facing a first direction, suitable for sewing the first material and other materials passing through the pull tube structure 300. Specifically, the pull tube structure 300 is built into the lower part of the loading platform 400, forming upper and lower layered channels, so that the first material and other materials are spatially isolated and pre-shaped before sewing. The upper channel constrains the first material to maintain a partially flattened posture, and the flattened part is suitable for the fit of the pressing structure 1000. The lower channel guides other materials to enter according to the required cross-section. The two converge at the exit of the needle assembly 900, ensuring that the stacking order and relative position meet the preset conditions. This layout makes full use of the internal space of the frame 100, shortens the feeding path, and avoids the exposed guide 310 from interfering with the operator. Meanwhile, the concealed design of the pull tube reduces the risk of external dust and oil contamination of the fabric, improving the cleanliness of the finished product. By integrating the guide, alignment, and sewing entrance into the same component, the system eliminates the need for additional positioning clamps and adjustment time. Even under continuous high-speed operation, it can maintain a stable stacking state, providing a reliable guarantee for uniform stitches and a smooth appearance, thus improving sewing quality and overall machine integration.
[0036] Reference Figures 8 to 12 In some embodiments, the pull tube structure 300 includes a first outer wall 340 and a second outer wall 350 protruding in a vertical direction. The first outer wall 340 and the second outer wall 350 are disposed on opposite sides of the pull tube structure 300 along a second direction. The first direction, the second direction and the vertical direction are perpendicular to each other. The outer surfaces of the first outer wall 340 and the second outer wall 350 are both suitable for attaching other materials.
[0037] The first outer wall 340 and the second outer wall 350 protrude vertically on both sides of the pull tube structure 300, forming a continuous and rigid guide facade. Other materials are clamped by the two outer walls from the moment they enter the lower channel of the pull tube, and are stably constrained along the second direction. The facade fit forces the material edges to fold upward synchronously, naturally presenting a regular U-shaped cross-section, maintaining a consistent covering posture without the need for additional pressure plates or manual pre-folding. The vertical protruding walls are integrally formed with the pull tube body, which not only strengthens the torsional rigidity of the entire component, but also effectively suppresses the lateral movement and rebound of the material during high-speed feeding, ensuring that each layer of material is always accurately aligned and has uniform tension at the needle inlet. This design achieves the three major functions of guiding, shaping and supporting simultaneously with the simplest outer wall shape, reducing the number of parts and adjustment links, providing a neat edge and stable layered state for subsequent sewing, significantly reducing the risk of scrap and the workload of equipment maintenance.
[0038] Reference Figures 1 to 14 The second aspect of this application provides a sewing device for sewing a hat front panel 20 and binding strips. The hat front panel 20 includes a hat body 23, a first section 21, and a second section 22. The first section 21 and the second section 22 are both connected to the same edge of the hat body 23. The sewing device is characterized by comprising the sewing system of any one of claims 1 to 7. The sewing device includes a pull tube structure 300 and a connecting frame 100. The pull tube structure 300 includes a guide member 310 and a separating member 320, with the separating member 320 disposed on the guide member 310. On the side facing the first direction, the guide 310 defines a first guide channel, which is adapted to allow the first piece 21 and the second piece 22 to pass through together. The separator 320 is adapted to separate the first piece 21 and the second piece 22 passing through the first channel 330, so that the first piece 21 and the second piece 22 are spaced apart along the second direction, which is perpendicular to the second direction. The outer wall of the pull tube structure 300 is adapted to fit the binding strip, which is capable of connecting the first piece 21 and the second piece 22 separated by the separator 320 to the opposite sides of the cap body 23 along the second direction.
[0039] Specifically, the sewing equipment of this application deeply integrates the sewing system of the above embodiment with the pull tube structure 300 that fits the front piece 20 of the hat body, so that the first piece 21, the second piece 22, and the binding strip of the front piece 20 of the hat body complete guiding, separation, covering, and sewing within the same feeding stroke. The guide member 310 of the pull tube structure 300 first allows the two pieces to pass through the first guide channel side by side to ensure that the entry posture is consistent. The subsequent separation member 320 quickly spreads the two pieces apart in the second direction at the channel exit to form a fixed interval. At the same time, the binding strip adheres to the outer wall of the pull tube and moves forward, and its two side edges naturally roll up and wrap the edges of the spread pieces respectively. With the help of the fan-shaped trajectory of the needle assembly 900 of the sewing system and the feeding power, the main body 23 of the hat body moves forward continuously. The binding strip and the two pieces complete positioning, covering, and sewing synchronously without additional power, completely eliminating the intermittent operations such as manual piece separation, strip alignment, and secondary presser foot. This integrated solution achieves both spacing and wrapping with a single pull tube, eliminating human error, ensuring symmetrical stitches and uniform edges, improving the consistency of finished product appearance and production efficiency, and reducing reliance on skilled workers.
[0040] Reference Figure 3 and Figure 4In some embodiments, the sewing device further includes an auxiliary structure 200, which includes a first support leg 210 and a second support leg 220 spaced apart along a second direction. Both the first support leg 210 and the second support leg 220 are adapted to extend into the inner side of the hat body 23 to assist the pressing structure 1000 in conforming to the inner side of the hat body 23. The auxiliary structure 200, through the symmetrical arrangement of the first support leg 210 and the second support leg 220 in the second direction, provides two-point rigid support from the inner side of the hat body 23, ensuring that the pressing structure 1000 can be stably pressed down from a preset position inside the hat body 23 without pressing down on the outer side of the hat body 23 to prevent wrinkles in the front panel 20. Specifically, after the support legs extend into the inner side, they expand the soft hat body 23 into a smooth curved surface, eliminating wrinkles and collapse, ensuring uniform force on the pressing surface, and preventing skipped stitches or uneven stitch widths caused by localized air pockets. Meanwhile, the inner support offsets part of the lateral force of the pressing structure 1000, effectively suppressing the lateral movement of materials during high-speed feeding. This auxiliary structure 200 replaces complex vacuum or clamping solutions with simple components, without adding extra power, ensuring the flatness and positioning accuracy of materials in the stitching area, while reducing the workload of equipment debugging and maintenance, providing a reliable guarantee for continuous, high-quality, and unattended production.
[0041] Reference Figure 5 In some embodiments, the sewing equipment further includes a feeding structure 500, which includes a gripper 510 and a rotating base 520. The gripper 510 is adapted to grip the front panel 20 of the hat body, and the gripper 510 is rotatably connected to the rotating base 520 to adjust the orientation of the front panel 20. The feeding structure 500, through the combination of the gripper 510 and the rotating base 520, integrates the gripping and orientation adjustment of the front panel 20 of the hat body into the same action cycle. After the gripper 510 completes gripping, the rotating base 520 can drive the gripper 510 to rotate in a horizontal or vertical plane, so that the front and rear ends of the hat panel and the orientation of the front and back sides are adjusted into place in one go, without the need for manual secondary placement or additional workstation flipping. This ensures that the placement angle is consistent each time, eliminating entry jamming or sewing thread skewing caused by differences in the orientation of the incoming material. The entire feeding process does not require the operator to reach into the equipment, which reduces labor intensity and improves operational safety. It provides a precise and directional material source for subsequent guiding, flattening, and sewing processes, effectively ensuring the continuity of the machine's operation and the consistency of the finished product's appearance.
[0042] The sewing system and sewing equipment of this application are described below with reference to a specific embodiment. (Refer to 1 to...) Figure 14The sewing system and sewing equipment disclosed in this invention systematically integrate feeding, guiding, flattening, separating, covering, sewing, cutting, and material collection functions to meet the automated sewing needs of the front piece 20 of the hat and the binding strip on a double-needle sewing machine 10. This replaces the inefficient processes of traditional manual piece separation, strip matching, feeding, and cutting. The sewing system is based on a frame 100, and sequentially includes a carrying platform 400, a pressing structure 1000, a needle assembly 900, a pull tube structure 300, a cutting blade assembly 800, and a material collection assembly 3000. The carrying platform 400 supports the main body 23 of the hat, while the pressing structure 1000 gently presses it from above, preventing fabric movement while retaining the ability to slide along the first direction by the needle. After the needle assembly 900 completes the sewing at the extended position, it moves along a fan-shaped trajectory to the end position, and pushes the front piece 20 of the cap body and the binding strip forward in sync, realizing an integrated structure of sewing and driving, eliminating the need for an additional feeding mechanism, simplifying the structure and improving cycle stability.
[0043] The pull tube structure 300 is located below the carrying platform 400 and contains a guide component 310 and a separator component 320. First, the first segment 21 and the second segment 22 enter side-by-side through the first guide channel. Then, at the exit, the separator component 320 instantly separates the two segments along the second direction, forming a fixed interval. Simultaneously, the outer wall of the pull tube adheres to the binding strip, causing its two sides to naturally curl upwards into a U-shape. This completes the triple action of feeding, segmenting, and wrapping during continuous movement in the first direction, ensuring that the binding strip symmetrically wraps the edges of the segments and preventing uneven tightness or gaps caused by manual wrapping. The cutting blade assembly 800 follows immediately downstream of the needle assembly 900, using the same feeding power to instantly cut off the previously sewn material. The inclined guide chute allows the material to automatically slide down to the collection area by gravity, keeping the worktable clean and preventing accumulation that could interfere with continuous production.
[0044] To further improve the straightness and flatness of material movement, the system is equipped with an auxiliary wheel set 2000. The rollers 2100 hold the fabric surface with a damped two-section bracket and can adaptively float according to changes in thickness, providing another positional limit while avoiding excessive compression. The first and second support feet 220 of the auxiliary structure 200 extend into the inner side of the cap body 23, forming a two-point internal support, echoing the pressing structure 1000, ensuring that the fabric in the sewing area is always taut and wrinkle-free, effectively improving stitch symmetry and appearance consistency. The feeding structure 500 uses a combination of grippers 510 and a rotating base 520. After gripping, the grippers 510 rotate around a vertical or horizontal axis to adjust the front and rear end sequence and front and back orientation of the cap piece in one go, eliminating manual piece placement, shortening the feeding cycle, and reducing the operator's labor intensity. In addition, the sewing equipment also includes a guiding mechanism 600 and a flattening mechanism 700. The guiding mechanism 600 has a second channel 610 that gradually narrows along the feeding direction to further ensure the flatness and positional accuracy of the material when it enters. The flattening mechanism 700 is used to unfold the front panel 20 of the hat body, so that the auxiliary structure 200 can extend into the inside of the main body 23 of the hat body. The auxiliary structure 200 presses down the main body 23 of the hat body, so that the main body 23 of the hat body moves to the pressing structure 1000 along with the movement of the first support foot 210 and the second support foot 220 for sewing.
[0045] The entire sewing equipment integrates the aforementioned functional modules into a single frame 100 according to the process sequence, forming a complete flow channel from automatic material feeding, guiding and flattening, piece covering, sewing and pulling to material collection. Material flows in one direction without manual transfer, significantly reducing cumulative errors caused by repetitive positioning. Simultaneously, the modular design makes maintenance and debugging more convenient, providing a reliable, compact, and low-energy-consumption technical solution for high-speed, high-quality, and large-scale production of hat products.

Any equivalent structural transformations made using the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
