[0092] Therefore, it can be understood that the hat piece sewing machine according to the embodiment of the present application has at least the following beneficial effects: the feeding device 20 grips two hat pieces to the eyeletting device 30, the eyeletting device 30 sequentially sews the eyelets of the two hat pieces, the feeding device 60 delivers the hat pieces from the eyeletting device 30 to the fitting device 40, the fitting device 40 fits the two hat pieces, and then the seaming device 50 is used for seaming. Through the hat piece sewing machine, the eyelets of two hat pieces can be sewn and the two hat pieces can be seamed at the same time instead of manually.

[0093] Reference Figures 1-2In some embodiments of the present application, the positioning device comprises a first positioning mechanism 71, which is arranged on the feeding device 20. The feeding device 20 further comprises a material supporting mechanism 22 and a first sliding mechanism 23. The material supporting mechanism 22 is arranged on the workbench 11 in a liftable manner. Two material supporting mechanisms 22 are arranged, and each is located below a corresponding one of the two grabbing mechanisms 21. The cap pieces are placed on the material supporting mechanisms 22. Two first positioning mechanisms 71 are arranged, and each is located below a corresponding one of the two material supporting mechanisms 22. The first positioning mechanisms 71 are configured to position the cap pieces on the material supporting mechanisms 22. The first sliding mechanism 23 is arranged on the workbench 11. The two grabbing mechanisms 21 are arranged on the output end of the first sliding mechanism 23. The first sliding mechanism 23 is configured to drive the grabbing mechanisms 21 away from or close to the eyeletting device 30.

[0094] In addition to the original two liftable grabbing mechanisms 21, the feeding device 20 is additionally provided with two material supporting mechanisms 22. The two material supporting mechanisms 22 are arranged on the workbench 11 in a liftable manner and are respectively located below the two grabbing mechanisms 21. When the cap pieces are placed on the sewing machine, they are first placed on the material supporting mechanisms 22 to provide support for subsequent grabbing and positioning. In order to further ensure the stability of the cap pieces on the material supporting mechanisms 22, two first positioning mechanisms 71 are arranged, which are symmetrically arranged and respectively located below the two material supporting mechanisms 22. The design of the first positioning mechanisms 71 enables them to effectively position the cap pieces on the material supporting mechanisms 22, preventing the cap pieces from moving or deviating during processing, thereby ensuring the accuracy and quality of sewing. In addition, the feeding device 20 further comprises a first sliding mechanism 23, which is arranged on the workbench 11, and the two grabbing mechanisms 21 are mounted on the output end of the first sliding mechanism 23. The first sliding mechanism 23 is configured to drive the grabbing mechanisms 21 to slide on the workbench 11, so that the grabbing mechanisms 21 can move away from or close to the eyeletting device 30. This design not only facilitates the feeding and discharging operations of the cap pieces, but also makes the entire sewing process more smooth and efficient. After the grabbing mechanisms 21 grab the cap pieces, the first sliding mechanism 23 drives the grabbing mechanisms 21 to accurately deliver the cap pieces to the eyeletting device 30 for sewing processing, thereby realizing the automated or semi-automated production of cap piece sewing.

[0095] Further, with reference to Figure 2In some embodiments of the present application, the first positioning mechanism 71 includes a first positioning rod 711 and a plurality of first limiting rods 712. The first positioning rod 711 can be inserted through the material supporting mechanism 22 and inserted into the embroidery eye of the cap piece. The plurality of first limiting rods 712 are arranged on the outer circumferential side of the cap piece. The first positioning mechanism 71 is mainly composed of the first positioning rod 711 and the plurality of first limiting rods 712, which work together to ensure the accurate positioning of the cap piece on the material supporting mechanism 22. The first positioning rod 711 is designed to be inserted through the material supporting mechanism 22 and inserted into the embroidery eye of the cap piece. This design uses the embroidery eye on the cap piece as a positioning point, allowing the first positioning rod 711 to securely hold the cap piece and prevent it from moving during subsequent processing. In addition, the embroidery eye of the cap piece can also be positioned. At the same time, the insertion method of the first positioning rod 711 ensures its close cooperation with the material supporting mechanism 22, enhancing the stability of the entire positioning system. In addition to the first positioning rod 711, the first positioning mechanism 71 also includes a plurality of first limiting rods 712. These first limiting rods 712 are arranged on the outer circumferential side of the cap piece, and their function is to further limit the position of the cap piece to prevent it from shifting sideways. The number and position of the first limiting rods 712 can be adjusted according to the shape and size of the cap piece to ensure the best positioning effect.

[0096] In summary, the first positioning mechanism 71 achieves accurate positioning of the cap piece on the material supporting mechanism 22 through the cooperation of the first positioning rod 711 and the first limiting rod 712. This design not only improves the automation level of the sewing machine, but also ensures the accuracy and stability of the sewing process, thereby improving the quality and production efficiency of the product.

[0097] Referring to Figure 1 and Figure 3 In some embodiments of the present application, the positioning device further includes a second positioning mechanism 72, which is arranged on the embroidery eye device 30. The embroidery eye device 30 includes a first sewing mechanism 31 and a first material pressing mechanism 32. The first sewing mechanism 31 is arranged on the workbench 11 and is configured to sew the embroidery eye on the cap piece. The first material pressing mechanism 32 is movably arranged on the workbench 11. The second positioning mechanism 72 is provided with two, which are arranged below the workbench 11. The second positioning mechanism 72 is configured to position the embroidery eye of the cap piece, and the first material pressing mechanism 32 is configured to press the cap piece against the workbench 11.

[0098] For the hat piece sewing machine, the positioning device further comprises a second positioning mechanism 72, which is arranged on the eyeletting device 30 and cooperates with other parts of the eyeletting device 30 to ensure the accurate positioning of the hat piece during the eyeletting sewing process. The eyeletting device 30 comprises a first sewing mechanism 31, which is fixedly arranged on the workbench 11 and configured to sew the eyelet on the hat piece. When the first sewing mechanism 31 is working, it is necessary to ensure the stable and accurate position of the hat piece to ensure the sewing quality of the eyelet. In order to achieve this goal, the eyeletting device 30 is also provided with a first pressing mechanism 32. The first pressing mechanism 32 is movably arranged on the workbench 11 and can be lowered to press the hat piece on the workbench 11 when needed, and at the same time, the hat piece is driven by the first sewing mechanism 31 to slide along the sewing track of the eyelet during the sewing process of the eyelet, so as to prevent the movement of the position of the hat piece relative to the first pressing mechanism 32 during the sewing process. In addition, two second positioning mechanisms 72 are arranged below the eyeletting device 30. The two second positioning mechanisms 72 are symmetrically arranged, and their main function is to position the eyelet position of the hat piece. When the hat piece is placed on the workbench 11, the second positioning mechanism 72 can accurately align with the eyelet of the hat piece, and when the second positioning mechanism 72 positions the eyelet of the hat piece, it cooperates with the first pressing mechanism 32 to ensure that the hat piece maintains a stable position during the sewing process.

[0099] Further, with reference to Figure 3 In some embodiments of the present application, the second positioning mechanism 72 comprises a second lifting piece 721 and a second positioning rod 722, the second positioning rod 722 is arranged on the output end of the second lifting piece 721, and the second lifting piece 721 is configured to drive the second positioning rod 722 to pass through the workbench 11 and be inserted into the eyelet of the hat piece.

[0100] The second positioning mechanism 72 is mainly composed of a second lifting piece 721 and a second positioning rod 722, which work together to achieve accurate positioning of the embroidery eye of the hat piece. The second lifting piece 721 is fixedly arranged below the workbench 11 and has an output end for driving the second positioning rod 722 to perform lifting movement. The second positioning rod 722 is firmly installed on the output end of the second lifting piece 721 and moves up and down with the driving of the second lifting piece 721. During the working process, when the hat piece is placed on the workbench 11 and is ready for embroidery eye sewing, the second lifting piece 721 drives the second positioning rod 722 to rise. The second positioning rod 722 penetrates the workbench 11 and is accurately inserted into the embroidery eye of the hat piece. After the second positioning mechanism 72 achieves the positioning of the embroidery eye of the hat piece, the first pressing mechanism 32 can press the hat piece on the sewing table of the first sewing mechanism 31 at the same time, and then the second lifting piece 721 drives the second positioning rod 722 to descend below the sewing table to avoid the hat piece, so that the first pressing mechanism 32 can press the hat piece and drive the hat piece to slide on the sewing table. This design not only ensures the stable position of the hat piece during sewing, but also guarantees the accuracy of embroidery eye sewing and the smooth progress of sewing.

[0101] Through the cooperation of the second lifting piece 721 and the second positioning rod 722, the second positioning mechanism 72 can quickly position the embroidery eye position of the hat piece and provide accurate positioning support for subsequent sewing work. This design not only improves the automation degree of the hat piece sewing machine, but also further improves the quality and production efficiency of the product.

[0102] Referring to Figure 1 and Figure 4 In some embodiments of the present application, the positioning device further comprises a fixing mechanism 73, which is arranged on the fitting device 40. The fitting device 40 comprises a second driving mechanism 41 and a turnover plate 43. The second driving mechanism 41 is rotatably arranged on the workbench 11 through the first driving mechanism 42, and the second driving mechanism 41 is arranged on the output end of the first driving mechanism 42. The first driving mechanism 42 is configured to drive the second driving mechanism 41 to rotate. The turnover plate 43 is provided with two plates, which are symmetrically arranged between the two plates. The two turnover plates 43 are respectively arranged horizontally on the output end of the second driving mechanism 41, and the two turnover plates 43 are oppositely arranged. The turnover plate 43 is used to support the hat piece, and the second driving mechanism 41 drives the turnover plate 43 to be able to turn over relatively, so that the hat pieces can be fitted with each other. The fixing mechanism 73 is provided with two, which are arranged below the turnover plate 43. The fixing mechanism 73 is configured to fix the hat piece.

[0103] For the hat piece sewing machine, the positioning device further comprises a fixing mechanism 73 arranged on the fitting device 40 to ensure the position of the hat piece during the fitting process. The fitting device 40 comprises a second driving mechanism 41 and a turnover plate 43. The second driving mechanism 41 is rotatably arranged on the workbench 11 by the first driving mechanism 42, which is configured as a power source to drive the second driving mechanism 41 to rotate. The output end of the second driving mechanism 41 is provided with two turnover plates 43, which are symmetrically arranged and respectively horizontally extended to support the hat piece. During the work process, when two hat pieces are transported to the fitting device 40, they are respectively placed on the two turnover plates 43. After receiving the instruction, the second driving mechanism 41 drives the turnover plates 43 to relatively turn over, so that the two hat pieces can be fitted with each other. This design not only realizes the automatic fitting of the hat piece, but also ensures the stability and accuracy during the fitting process. In order to prevent the hat piece from slipping during the turnover fitting process, two fixing mechanisms 73 are arranged below the fitting device 40. The two fixing mechanisms 73 are respectively located below the two turnover plates 43, and their main function is to fix the position of the hat piece. When the turnover plate 43 supports the hat piece and turns over to fit, the fixing mechanism 73 can ensure that the position of the hat piece is accurately aligned, so as to ensure the quality of the fitted hat piece. At this time, the first driving mechanism 42 can drive the second driving mechanism 41 to make the turnover plate 43 turned over from the vertical state to the horizontal state, so as to turn over the fitted hat piece to the horizontal state, which is convenient for the clamping and transfer of the feeding device 60.

[0104] Further, in some embodiments of the present application, the fixing mechanism 73 comprises a driving member (not shown in the figure) and a fixing member (not shown in the figure), the fixing member is arranged on the output end of the driving member, the driving member is configured to drive the fixing member to pass through the turnover plate 43, and the fixing member is configured to be capable of contacting the hat piece to fix the hat piece on the turnover plate 43.

[0105] The fixing mechanism 73 is composed of a driving part and a fixing part, which are tightly matched to prevent the cap pieces from slipping during the bonding process. The driving part is stably arranged below the bonding device 40, specifically below the turnover plate 43. It has an output end for driving the fixing part to perform lifting or approaching motion. The fixing part is firmly installed on the output end of the driving part and moves away from or approaches the cap pieces with the driving of the driving part. During the bonding process of the cap pieces, when the two cap pieces are placed on the turnover plate 43 and are ready for bonding, the driving part will receive instructions to drive the fixing part to approach the cap pieces. The fixing part will pass through the reserved hole on the turnover plate 43 and accurately bond or insert into the cap pieces. This design not only ensures the stable position of the cap pieces during the bonding process, but also guarantees the accurate alignment between the cap pieces, thereby improving the quality of the bonded cap pieces. Desirably, the fixing part can be a vacuum suction accessory, and the driving part drives the fixing part to approach the cap pieces, so that the fixing part approaches and tightly bonds the cap pieces, thereby the cap pieces can be adsorbed on the vacuum suction accessory by using the negative pressure generated by vacuum suction, to realize the fixation and positioning of the cap pieces; the fixing part can also be a needle suction cup, and the driving part drives the needle in the fixing part to approach and penetrate into the cap pieces, thereby the cap pieces can be fixed and positioned on the turnover plate 43; or even it can be a clamping or other fixing form. In this embodiment, the specific structure of the fixing mechanism 73 can not be specifically limited, as long as it can realize the fixation and positioning of the cap pieces.

[0106] By the cooperation of the driving part and the fixing part, the fixing mechanism 73 can ensure the fixation of the position of the cap pieces and provide accurate positioning support for the subsequent bonding work. This design not only improves the automation degree of the cap sewing machine, but also further guarantees the quality and production efficiency of the product, so that the bonding process of the cap pieces is more stable, accurate and efficient.

[0107] Further, with reference to Figure 4In some embodiments of the present application, the fitting device 40 further comprises a second pressing mechanism 44, which is arranged on the rack 10 above the turnover plate 43, and the second pressing mechanism 44 comprises a liftable pressing block 441 for pressing the cap pieces against the turnover plate 43. Taking the fixing mechanism 73 as an example, the fitting device 40 is further equipped with a second pressing mechanism 44 to ensure the stability and accuracy of the cap pieces during the fitting process. The second pressing mechanism 44 is arranged on the rack 10 and above the turnover plate 43. This position design enables the second pressing mechanism 44 to play a key role in the cap fitting process. The core component of the second pressing mechanism 44 is the liftable pressing block 441, which can move up and down according to actual needs. Before the positioning of eyeletting, when two cap pieces are placed on the turnover plate 43 and ready for fitting, the second pressing mechanism 44 will receive instructions to drive the pressing block 441 to descend. The pressing block 441 will accurately press against the cap pieces, firmly fixing them on the turnover plate 43; at this time, the driving part of the fixing mechanism 73 drives the fixing part to rise. The fixing part will pass through the reserved hole on the turnover plate 43 and be accurately inserted into the cap pieces. This design not only ensures the stable position of the cap pieces during the fitting process, preventing the cap pieces from slipping off when the turnover plate 43 is turned over, but also guarantees the accurate alignment of the cap pieces. This design not only prevents the cap pieces from moving or shifting during the fitting process, but also ensures the smooth progress of the fitting process.

[0108] Referring to Figure 1 and Figure 5 In some embodiments of the present application, the positioning device further comprises a third positioning mechanism 74, which is arranged on the joint device 50, and the joint device 50 comprises a second sewing mechanism 51 and a third pressing mechanism 52. The second sewing mechanism 51 is arranged on the workbench 11, and the second sewing mechanism 51 is configured to sew two cap pieces; the third pressing mechanism 52 is movably arranged on the workbench 11, the third positioning mechanism 74 is located below the workbench 11, the third positioning mechanism 74 is configured to align the edges of the two fitted cap pieces with each other, and the third pressing mechanism 52 is configured to press the cap pieces against the workbench 11.

[0109] For the hat piece sewing machine, the positioning device is further provided with a third positioning mechanism 74, which is arranged on the jointing device 50 to ensure the accurate alignment and stable fixation of the hat piece during the sewing process. The jointing device 50 includes a second sewing mechanism 51 and a third pressing mechanism 52. The second sewing mechanism 51 is fixedly arranged on the workbench 11, which is responsible for sewing the two pieces of hat pieces that have been pasted together. In order to ensure the accuracy and beauty of the sewing, the edges of the hat pieces must be aligned with each other. In order to achieve this goal, the third positioning mechanism 74 is arranged below the workbench 11. The main function of the third positioning mechanism 74 is to ensure that the edges of the two pieces of hat pieces that have been pasted together can be aligned with each other. When the hat pieces are placed on the workbench 11 ready for sewing, the third positioning mechanism 74 will accurately position the edge position of the hat pieces, ensuring that they remain aligned during the sewing process. In addition, the jointing device 50 is also equipped with a third pressing mechanism 52. The third pressing mechanism 52 is movably arranged on the workbench 11, which can be lowered and press the hat piece against the workbench 11 when needed, and at the same time, the third pressing mechanism 52 can also drive the hat piece to slide along the sewing track on the sewing table of the second sewing mechanism 51 during the sewing process. This design not only prevents the hat piece from moving or shifting during the sewing process, but also ensures the smooth progress of the sewing process.

[0110] In summary, the third positioning mechanism 74, the second sewing mechanism 51 and the third pressing mechanism 52 together constitute the core part of the jointing device 50. The third positioning mechanism 74 ensures the accurate alignment of the edges of the hat pieces, and the third pressing mechanism 52 ensures the stability of the hat pieces during the sewing process. This design not only improves the automation level of the hat piece sewing machine, but also further improves the quality and production efficiency of the product.

[0111] Further, with reference to Figure 5 and Figure 7 In some embodiments of the present application, the third positioning mechanism 74 includes a pushing piece 741 and an alignment piece 742. The pushing piece 741 is arranged below the second sewing mechanism 51 and includes a pushing rod movably arranged below the second sewing mechanism 51. The alignment piece 742 is arranged below the second sewing mechanism 51 and located on one side of the pushing piece 741. The alignment piece 742 includes three or more fourth positioning rods 7421, which are movably arranged in the workbench 11. The fourth positioning rods 7421 are located on the outer circumferential side of the hat piece. The pushing rod is configured to push the hat piece into the alignment piece 742 to align the edges between the two hat pieces.

[0112] The third positioning mechanism 74 mainly consists of two parts, a pushing component 741 and an alignment component 742. The pushing component 741 is arranged below the second sewing mechanism 51, and its core component is a pushing rod. The pushing rod is movably arranged below the second sewing mechanism 51 and can be extended to push the hat pieces to the designated position when needed. The alignment component 742 is arranged on one side of the pushing component 741 and also below the second sewing mechanism 51. The alignment component 742 includes three or more fourth positioning rods 7421, which are movably arranged on the sewing table of the second sewing mechanism 51 and located on the outer circumferential side of the hat pieces. When the hat pieces are pushed by the pushing rod to the alignment component 742, the fourth positioning rods 7421 will be raised to contact the edges of the hat pieces, thereby aligning the edges of the two hat pieces. In the specific working process, when the two well-fitted hat pieces are placed on the sewing table of the second sewing mechanism 51 to prepare for sewing, the pushing rod will first extend to push the hat pieces to the position of the alignment component 742. Then, the fourth positioning rods 7421 are raised to closely contact the edges of the hat pieces, ensuring that the edges of the two hat pieces can be aligned with each other. This design not only improves the accuracy of sewing but also ensures that the sewn hat pieces have a neat and beautiful appearance.

[0113] Referring to Figure 1 and Figure 8 In some embodiments of the present application, the hat piece sewing machine further comprises a discharging device 80 arranged on the rack 10, and the discharging device 80 is located on one side of the jointing device 50. The discharging device 80 is configured to send the two well-sewn hat pieces out of the jointing device 50.

[0114] For the hat piece sewing machine, the discharging device 80 is arranged on the rack 10 and located on one side of the jointing device 50. The main function of the discharging device 80 is to smoothly and efficiently send the two well-sewn hat pieces out of the jointing device 50 for subsequent processing or packaging.

[0115] In the specific working process, after the two hat pieces are sewn in the jointing device 50, they will be conveyed to the position of the discharging device 80. The discharging device 80 usually includes a series of conveyor belts, rollers or clamps and other conveying mechanisms, which can work together to smoothly send the well-sewn hat pieces out of the jointing device 50. In order to ensure the smoothness and accuracy of discharging, the design of the discharging device 80 fully considers the size, shape and material characteristics of the hat pieces. The speed, position and spacing of the conveyor belts or rollers can be adjusted according to actual needs to ensure that the hat pieces are not damaged or deformed during discharging.

[0116] Specifically, referring to Figure 1 and Figure 8In some embodiments of the present invention, the discharge device 80 includes a first clamping mechanism 81, a storage bin 82, and a lifting plate 83. The first clamping mechanism 81 is disposed on the workbench 11 and is configured to clamp two sewn cap pieces. The storage bin 82 is disposed on one side of the first clamping mechanism 81 and is used to store the cap pieces. The lifting plate 83 is vertically and vertically disposed in the storage bin 82 and is configured to support the cap pieces and place them into the storage bin 82.

[0117] The discharge device 80 includes a first clamping mechanism 81, a storage bin 82, and a lifting plate 83. The first clamping mechanism 81 is mounted on the workbench 11, adjacent to the sewing device 50. After two cap pieces are sewn together in the sewing device 50, the first clamping mechanism 81 quickly clamps the sewn cap pieces to ensure they do not scatter or shift during subsequent transport. The storage bin 82 is located to one side of the first clamping mechanism 81 and is used to store the sewn cap pieces. The design of the storage bin 82 fully considers the storage needs and space utilization of the cap pieces, accommodating a certain number of cap pieces while maintaining their neatness and order. A lifting plate 83 is also installed in the storage bin 82. The main function of the lifting plate 83 is to support the cap pieces and place them smoothly into the storage bin 82. When the first clamping mechanism 81 conveys the sewn cap pieces to the opening of the storage bin 82, the lifting plate 83 rises, catches the cap pieces, and lowers to place them in the storage bin 82. Subsequently, the lifting plate 83 will be pulled away from the storage bin 82 and rise to prepare for the insertion of the next cap piece.

[0118] According to a second aspect embodiment of the present invention, the hat panel sewing method is applied to a hat panel sewing machine, and the hat panel sewing mechanism may refer to any of the embodiments of the first aspect described above and refer to... Figures 1-8 The hat piece sewing method includes the following steps:

[0119] Simultaneously, two cap pieces are grasped and conveyed, and the two cap pieces are placed symmetrically between them; the cap sewing machine includes a feeding device 20, which includes two liftable gripping mechanisms 21, two material supporting mechanisms 22, and a first sliding mechanism 23. The two gripping mechanisms 21 are set on the output end of the first sliding mechanism 23, and the first sliding mechanism 23 is configured to drive the gripping mechanisms 21 to move. The two gripping mechanisms 21 are symmetrically arranged between them, and the positions of the two gripping mechanisms 21 correspond one-to-one with the positions of the two material supporting mechanisms 22. The two cap pieces are placed on the material supporting mechanisms 22 respectively.

[0120] The eyelets of two hat pieces are sewn in sequence; the hat piece sewing machine includes an eyelet device 30, which is located on one side of the feeding device 20. The feeding device 20 feeds the two hat pieces to the eyelet device 30, which is configured to sew the eyelets on the hat pieces.

[0121] The two pieces of cap pieces are attached to each other. The cap piece sewing machine further comprises a jointing device 40 located on one side of the eyeletting device 30, and the jointing device 40 is configured to flip the symmetrically placed cap pieces relative to each other to attach the two cap pieces to each other;

[0122] The two pieces of cap pieces are attached to each other. The cap piece sewing machine further comprises a jointing device 40 located on one side of the eyeletting device 30, and the jointing device 40 is configured to flip the symmetrically placed cap pieces relative to each other to attach the two cap pieces to each other;

[0123] The two pieces of cap pieces are attached to each other. The cap piece sewing machine further comprises a jointing device 40 located on one side of the eyeletting device 30, and the jointing device 40 is configured to flip the symmetrically placed cap pieces relative to each other to attach the two cap pieces to each other;

[0124] The cap piece sewing method of the present application is specifically applied to a cap piece sewing machine with exquisite design, and the method covers a series of orderly and efficient steps to ensure that the whole process from grabbing to sewing of the cap pieces can maintain high quality and efficiency.

[0125] Firstly, the method starts with grabbing and conveying two pieces of cap pieces at the same time. The two pieces of cap pieces are placed symmetrically to ensure the smooth progress of subsequent processing steps. The feeding device 20 of the cap piece sewing machine is responsible for this task, which includes two liftable grabbing mechanisms 21, two material holding mechanisms 22 and a first sliding mechanism 23. The two grabbing mechanisms 21 are arranged symmetrically on the output end of the first sliding mechanism 23 and are driven to move by the first sliding mechanism 23. The grabbing mechanisms 21 are symmetrically arranged between the first sliding mechanism 23 and the material holding mechanisms 22. The cap pieces are placed on the material holding mechanisms 22 respectively, and then grabbed and conveyed to the next process by the grabbing mechanisms 21.

[0126] Next, the eyelets of the two pieces of cap pieces are sewn in turn. The eyeletting device 30 of the cap piece sewing machine is located on one side of the feeding device 20 and is responsible for receiving and sewing the eyelets of the cap pieces. The feeding device 20 accurately conveys the two pieces of cap pieces to the eyeletting device 30, and the eyeletting device 30 sews the eyelets of the two pieces of cap pieces according to the predetermined program.

[0127] Subsequently, the two pieces of cap pieces are attached to each other. This step is completed by the jointing device 40 of the cap piece sewing machine, which is located on one side of the eyeletting device 30. The jointing device 40 is configured to flip the symmetrically placed cap pieces relative to each other to attach them to each other. During this process, the jointing device 40 ensures the accurate alignment and close attachment between the cap pieces.

[0128] Subsequently, the two pieces of cap pieces are sewn together. The seaming device 50 is located on the other side of the attaching device 40. The seaming device 50 is configured to seam the two pieces of cap pieces together, and ensure the firmness and beauty of the seam by precise sewing technology.

[0129] Finally, the sewn cap pieces are discharged.

[0130] It should be noted that the step of conveying the cap pieces: the feeding device 60 of the cap sewing machine is arranged on one side of the eyeletting device 30, the attaching device 40 and the seaming device 50, and is responsible for conveying the cap pieces from the three devices in turn. The feeding device 60 ensures the smooth flow of the cap pieces in the processing process, and improves the overall production efficiency.

[0131] In summary, it can be understood that the cap sewing method according to the embodiment of the application has at least the following beneficial effects: the cap sewing method is applied to the cap sewing machine, the feeding device 20 grasps the two pieces of cap pieces to the eyeletting device 30, the eyeletting device 30 sequentially sews the eyelets of the two pieces of cap pieces, the cap pieces are conveyed by the feeding device 60, and the cap pieces are moved from the eyeletting device 30 to the attaching device 40, the attaching device 40 attaches the two pieces of cap pieces, and then the seaming device 50 is used for sewing. Through the cap sewing machine, the eyelets of the two pieces of cap pieces can be sewn simultaneously and the two pieces of cap pieces can be sewn by replacing manual operation.

[0132] In some embodiments of the application, the cap sewing machine further comprises a positioning device, the positioning device is located in the feeding device 20, the eyeletting device 30, the attaching device 40 and the seaming device 50, and the positioning device is configured to position the position of the cap pieces; wherein the positioning device comprises a first positioning mechanism 71, a first positioning rod 711 and a plurality of first limiting rods 712, the first positioning rod 711 is arranged in the material supporting mechanism 22 and is inserted into the eyelets of the cap pieces, and the plurality of first limiting rods 712 are located on the outer circumferential side of the cap pieces.

[0133] The step of simultaneously grasping and conveying the two pieces of cap pieces comprises the following steps:

[0134] After the grasping mechanism 21 grasps the cap pieces, the cap pieces are lifted to the height of the first positioning rod 711 and the first limiting rod 712, so that the cap pieces are separated from the first positioning mechanism 71.

[0135] The first sliding mechanism 23 drives the grasping mechanism 21 to move towards the eyeletting device 30, so that the grasping mechanism 21 places the cap pieces on the eyeletting device 30.

[0136] The cap sewing machine of the application further comprises a positioning device, which is distributed in the feeding device 20, the eyeletting device 30, the attaching device 40 and the seaming device 50, and its core function is to accurately position the position of the cap pieces, so that each processing step can be accurately and accurately performed.

[0137] In the positioning device, the first positioning rod 711 of the first positioning mechanism 71 and the first limiting rods 712 cooperated with the feeding device 20 together realize the accurate positioning of the hat pieces. Specifically, the first positioning rod 711 is arranged in the material supporting mechanism 22 and is inserted into the embroidery eye of the hat piece, which not only stabilizes the position of the hat piece but also provides an accurate positioning reference for the subsequent embroidery eye sewing. Meanwhile, the first limiting rods 712 located on the outer circumferential side of the hat piece ensure that the hat piece does not deviate from the predetermined position during the processing.

[0138] In the step of simultaneously grabbing and conveying two hat pieces, the positioning device plays a crucial role. After the grabbing mechanism 21 grabs the hat pieces, it drives the hat pieces to rise to the height of the first positioning rod 711 and the first limiting rods 712. During this process, the hat pieces gradually leave the direct constraint of the first positioning mechanism 71, but the position of the hat pieces remains stable and accurate through the accurate positioning of the first positioning rod 711 and the first limiting rods 712 and the stable grabbing of the grabbing mechanism 21.

[0139] Subsequently, the first sliding mechanism 23 is started, driving the grabbing mechanism 21 to move towards the embroidery eye device 30. During this movement, the grabbing mechanism 21 firmly holds the hat pieces, ensuring that they do not scatter or shift due to movement. Finally, the grabbing mechanism 21 accurately places the hat pieces on the embroidery eye device 30, fully preparing for the subsequent embroidery eye sewing step.

[0140] In some embodiments of the present application, the embroidery eye device 30 includes a first sewing mechanism 31 configured to sew the embroidery eye on the hat piece and a first material pressing mechanism 32 configured to press the hat piece below the first sewing mechanism 31. The positioning device includes two second positioning mechanisms 72, which are arranged below the first material pressing mechanism 32. The second positioning mechanisms 72 are configured to position the embroidery eye of the hat piece and include a second lifting piece 721 and a second positioning rod 722 arranged on the output end of the second lifting piece 721. The second lifting piece 721 is configured to drive the second positioning rod 722 to be inserted into the embroidery eye of the hat piece.

[0141] The step of sequentially sewing the embroidery eyes of two hat pieces also includes the following steps:

[0142] The second lifting piece 721 drives the second positioning rod 722 to rise so that the second positioning rod 722 is inserted into the embroidery eye of the hat piece.

[0143] The first material pressing mechanism 32 presses the hat piece onto the sewing table surface of the first sewing mechanism 31.

[0144] The second lifting member 721 drives the second positioning rod 722 to descend, so that the second positioning rod 722 is separated from the embroidery eye of the hat piece;

[0145] The first pressing mechanism 32 presses the hat piece and drives the hat piece to slide on the sewing table of the first sewing mechanism 31, and the first sewing mechanism 31 sequentially sews the embroidery eyes of the two hat pieces.

[0146] On the basis of the hat piece sewing method in the above embodiment, the design of the embroidery eye device 30 further refines the process of embroidery eye sewing, ensuring the accurate sewing of the embroidery eye of the hat piece. The embroidery eye device 30 mainly consists of the first sewing mechanism 31 and the first pressing mechanism 32, which work together to achieve efficient sewing of the embroidery eye of the hat piece. The first sewing mechanism 31 is configured to accurately sew the embroidery eye on the hat piece. The first pressing mechanism 32 is responsible for stably pressing the hat piece below the first sewing mechanism 31 and driving the hat piece to slide along the sewing track on the sewing table of the first sewing mechanism 31, ensuring that the hat piece does not move or deform during sewing and that the sewing of the embroidery eye proceeds smoothly.

[0147] In order to further improve the accuracy of embroidery eye sewing, two second positioning mechanisms 72 are specially provided in the positioning device, which are located below the first pressing mechanism 32 and are used to position the embroidery eye of the hat piece. The second positioning mechanism 72 consists of a second lifting member 721 and a second positioning rod 722, and the second positioning rod 722 is arranged on the output end of the second lifting member 721.

[0148] When sequentially sewing the embroidery eyes of the two hat pieces, first, the second lifting member 721 drives the second positioning rod 722 to ascend, so that the second positioning rod 722 is accurately inserted into the embroidery eye of the hat piece, providing an accurate positioning reference for sewing. Then, the first pressing mechanism 32 presses the hat piece on the sewing table of the first sewing mechanism 31, ensuring that the hat piece remains stable during sewing.

[0149] Then, the second lifting member 721 drives the second positioning rod 722 to descend, so that the second positioning rod 722 is separated from the embroidery eye of the hat piece, leaving space for sewing operation. At this time, the first pressing mechanism 32 continues to press the hat piece and drives the hat piece to slide on the sewing table of the first sewing mechanism 31. The first sewing mechanism 31 sequentially sews the embroidery eyes of the two hat pieces according to the predetermined program and the sewing track, ensuring the sewing quality and efficiency of the embroidery eye.

[0150] In some embodiments of the present application, the fitting device 40 comprises two reversible turning plates 43 and a second pressing mechanism 44. The two turning plates 43 are symmetrically arranged and horizontally placed. The turning plates 43 can be reversely turned to fit the two hat pieces together. The second pressing mechanism 44 is above the turning plates 43 and presses the hat pieces on the turning plates 43. The positioning device comprises two fixing mechanisms 73, which are below the turning plates 43 and configured to fix the position of the hat pieces. The fixing mechanism 73 comprises a driving part and a fixing part. The fixing part is on the output end of the driving part. The driving part is configured to drive the fixing part through the turning plates 43. The fixing part is configured to contact the hat pieces to fix the hat pieces on the turning plates 43.

[0151] The step of fitting the two symmetrically placed hat pieces further comprises the following steps:

[0152] The second pressing mechanism 44 presses the hat pieces on the turning plates 43.

[0153] The driving part drives the fixing part to pass through the turning plates 43 and contact the hat pieces to fix the hat pieces on the turning plates 43.

[0154] The two turning plates 43 are reversely turned to fit the two hat pieces together. The driving part drives the fixing part to release the hat pieces.

[0155] Under the framework of the hat piece sewing method of the foregoing embodiments, the fitting device 40 realizes the precise fitting of the two hat pieces. The fitting device 40 comprises two reversible turning plates 43 and a second pressing mechanism 44. The cooperation of the two ensures the efficiency and accuracy of the hat piece fitting process. The two turning plates 43 are symmetrically arranged and initially horizontally placed. This design enables the two hat pieces to be smoothly placed on the turning plates 43, preparing for the subsequent fitting operation. The turning plates 43 have the function of reversely turning, which is the key to realizing the fitting of the hat pieces.

[0156] The second pressing mechanism 44 is above the turning plates 43 and presses the hat pieces on the turning plates 43, ensuring that the fixing part of the fixing mechanism 73 is inserted into the embroidery eye of the hat piece to fix the position of the hat piece and position the hat piece. To further improve the accuracy of fitting, the positioning device is specially provided with two fixing mechanisms 73, which are below the two turning plates 43. The fixing mechanism 73 is composed of a driving part and a fixing part. The fixing part is on the output end of the driving part.

[0157] The fixing mechanism 73 plays an important role in the process of attaching two hat pieces placed symmetrically to each other. First, the second pressing mechanism 44 firmly presses the hat pieces against the turnover plate 43, ensuring that the position of the hat pieces does not change. Then, the driving member drives the fixing member to pass through the turnover plate 43 and approach and tightly attach or insert the hat pieces, providing a precise position reference for attachment and preventing the position of the hat pieces from slipping during the turnover process.

[0158] Subsequently, while the two turnover plates 43 are turned over to bring the two hat pieces closer to each other and finally attach them together, the driving member drives the fixing member to release the eyelet of the hat pieces. During this process, the precise positioning of the fixing mechanism 73 ensures the accuracy and consistency of the hat piece attachment.

[0159] In some embodiments of the present application, the joint device 50 includes a second sewing mechanism 51 configured to sew two hat pieces and a third pressing mechanism 52 configured to press the hat pieces against the sewing table of the second sewing mechanism 51; the positioning device further includes a third positioning mechanism 74 located below the sewing table of the second sewing mechanism 51, the third positioning mechanism 74 being configured to align the edges of the two attached hat pieces with each other; the third positioning mechanism 74 includes a pushing member 741 and an alignment member 742, the alignment member 742 including three or more fourth positioning rods 7421, the fourth positioning rods 7421 being liftably arranged in the sewing table of the second sewing mechanism 51, the fourth positioning rods 7421 being located on the outer circumferential side of the hat pieces, the pushing member 741 being configured to push the hat pieces into the alignment member 742 to align the edges between the two hat pieces by the alignment member 742;

[0160] The step of sewing two attached hat pieces includes the following steps:

[0161] The pushing member 741 pushes the hat pieces into the alignment member 742 to align the edges between the two hat pieces by the alignment member 742;

[0162] The third pressing mechanism 52 presses the hat pieces against the sewing table of the second sewing mechanism 51 at least once;

[0163] The fourth positioning rods 7421 are lowered below the sewing table of the second sewing mechanism 51;

[0164] The third pressing mechanism 52 presses the hat pieces and drives the hat pieces to slide on the sewing table of the second sewing mechanism 51, and the second sewing mechanism 51 sews the two hat pieces.

[0165] On the basis of the hat piece sewing method described in the foregoing embodiments, the design of the jointing device 50 further perfects the hat piece sewing process. The jointing device 50 mainly consists of a second sewing mechanism 51 and a third pressing mechanism 52, which jointly realize the precise sewing of two hat pieces. The second sewing mechanism 51 is the core of the sewing operation, which is configured to sew the two hat pieces that have been pasted. The third pressing mechanism 52 is responsible for stably pressing the hat pieces against the sewing table of the second sewing mechanism 51, ensuring that the hat pieces do not move or deform during the sewing process. In order to improve the accuracy of sewing, the positioning device is specially provided with a third positioning mechanism 74. The third positioning mechanism 74 is located below the sewing table of the second sewing mechanism 51, and its main function is to align the edges of the two pasted hat pieces with each other. The third positioning mechanism 74 consists of a pushing piece 741 and an alignment piece 742, and the alignment piece 742 includes three or more fourth positioning rods 7421, which are liftably arranged in the sewing table of the second sewing mechanism 51 and located at the outer circumferential side of the hat pieces.

[0166] When sewing two mutually pasted hat pieces, the third positioning mechanism 74 plays a key role. First, the pushing piece 741 pushes the hat pieces into the alignment piece 742, so that the alignment piece 742 can accurately align the edges between the two hat pieces. This step ensures the accurate butt joint of the hat piece edges during sewing, improving the sewing quality.

[0167] Next, the third pressing mechanism 52 presses the hat pieces against the sewing table of the second sewing mechanism 51 at least once, further stabilizing the position of the hat pieces. Then, the fourth positioning rods 7421 are lowered below the sewing table of the second sewing mechanism 51 to create space for the sewing operation.

[0168] Finally, the third pressing mechanism 52 continues to press the hat pieces and drives the hat pieces to slide along the sewing track on the sewing table of the second sewing mechanism 51. The second sewing mechanism 51 then sews the two hat pieces according to the predetermined program. During this process, the accurate alignment of the third positioning mechanism 74 and the stable pressing of the third pressing mechanism 52 together ensure the accuracy and consistency of the sewing.

[0169] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the above-described embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the application.
