[0039] Specifically, the utility model discloses a kind of feeding devices 3, especially suitable for sewing machine of bending eyebrow brim 1.The sewing machine includes sewing mechanism 2, and the feeding device 3 of the utility model is designed for efficient, accurate feeding, to improve sewing quality and production efficiency.Feeding device 3 includes a support cylinder 10, which is located below sewing mechanism 2, and is designed as a cylinder.This design enables bending eyebrow brim 1 to move freely along the axial direction of support cylinder 10.The surface of support cylinder 10 is smooth to reduce friction with bending eyebrow brim 1, ensuring smooth feeding process.At one end of support cylinder 10, first feeding mechanism 20 is provided.First feeding mechanism 20 can move along the axial direction of support cylinder 10.First feeding mechanism 20 contains first pressing assembly 21, which includes first pressing component 211.First pressing component 211 is movably arranged above support cylinder 10 and moves up and down by appropriate mechanism (such as air cylinder, motor drive, etc.).When first pressing component 211 is pressed down, it can tightly press bending eyebrow brim 1 on the outer surface of support cylinder 10.On the outside of the other end of support cylinder 10, second feeding mechanism 30 is rotatably arranged.Second feeding mechanism 30 is located below sewing mechanism 2 and is designed with a clamping structure to fix one end of bending eyebrow brim 1.Second feeding mechanism 30 can also move along the axial direction of support cylinder 10 to adapt to the sewing of bending eyebrow brim 1.More importantly, second feeding mechanism 30 can rotate around the axis of support cylinder 10 on the lateral side of support cylinder 10.This design enables second feeding mechanism 30 to move bending eyebrow brim 1 on the outer surface of support cylinder 10, thereby achieving precise feeding control, and then sewing at different positions of bending eyebrow brim 1, finally completing sewing on bending eyebrow brim 1.

[0040] In use, first place bending eyebrow brim 1 on support cylinder 10 and press it by first pressing component 211 of first feeding mechanism 20.Then, use first feeding mechanism 20 to deliver bending eyebrow brim 1 to the position of second feeding mechanism 30, and use second feeding mechanism 30 to clamp and fix bending eyebrow brim 1.Next, adjust the position of second feeding mechanism 30 according to sewing requirements, and fix bending eyebrow brim 1 by its clamping structure.Finally, start the sewing machine, and second feeding mechanism 30 starts to rotate around the axis of support cylinder 10, and drives bending eyebrow brim 1 to move on the outer surface of support cylinder 10 to change the position of bending eyebrow brim 1 relative to sewing mechanism 2, so that sewing mechanism 2 sews on bending eyebrow brim 1.Because bending eyebrow brim 1 is tightly pressed on support cylinder 10, and the feeding process is controlled by machinery, the accuracy of sewing and production efficiency can be significantly improved.

[0041] Therefore, it can be understood that the feeding device 3 has at least the following beneficial effects: firstly, the first feeding mechanism 20 is used to convey the curved brim 1 to the second feeding mechanism 30, and then the second feeding mechanism 30 is used to clamp the curved brim 1, and at the same time, the second feeding mechanism 30 is used to drive the curved brim 1 to slide on the outer surface of the supporting cylinder 10, so as to change the relative position of the curved brim 1 relative to the sewing mechanism 2, and then the sewing mechanism 2 is used to sew on the curved brim 1. The first feeding mechanism 20 and the second feeding mechanism 30 can replace manual feeding and avoid relying on the proficiency of manual work, thereby improving the production efficiency and the sewing quality.

[0042] Further, with reference to Figures 1 to 3 In some embodiments of the present application, the first feeding mechanism 20 further comprises a first sliding plate 23, the first sliding plate 23 being slidingly arranged on the outer surface of the supporting cylinder 10, the first pressing assembly 21 being arranged on the first sliding plate 23, the first feeding mechanism 20 further comprising a first driving assembly 22, the first driving assembly 22 being arranged in the supporting cylinder 10, the output end of the first driving assembly 22 being connected to the first sliding plate 23, one end of the curved brim 1 abutting one side of the first sliding plate 23, the first driving assembly 22 driving the first sliding plate 23 to slide along the axis direction of the supporting cylinder 10, so as to make the curved brim 1 slide into the second feeding mechanism 30.

[0043] Specifically, according to the further refinement of the present application, the first feeding mechanism 20 is additionally provided with the first sliding plate 23 and the first driving assembly 22 on the basis of the first pressing assembly 21, so as to realize higher precision and automation of the feeding process. The first sliding plate 23 is slidingly arranged on the outer surface of the supporting cylinder 10 and can freely slide along the axis direction of the supporting cylinder 10. The first pressing assembly 21 is fixedly installed on the first sliding plate 23 and moves synchronously with the first sliding plate 23. In order to drive the first sliding plate 23 to slide along the axis direction of the supporting cylinder 10, the first driving assembly 22 is built in the first feeding mechanism 20. The first driving assembly 22 can be a motor-driven lead screw mechanism, a pneumatic cylinder or other suitable driving device, and the output end thereof is connected to the first sliding plate 23. When the first driving assembly 22 is started, it will drive the first sliding plate 23 to move along the axis direction of the supporting cylinder 10, and then drive the first pressing assembly 21 and the curved brim 1 to move together.

[0044] In actual operation, one end of the curved brim 1 will abut against one end side of the first sliding plate 23. When the first driving assembly 22 is activated, the first sliding plate 23 will slide along the axis direction of the support cylinder 10, while pushing the curved brim 1 to move together. Due to the pressing effect of the first pressing assembly 21, the curved brim 1 will be tightly fitted on the outer surface of the support cylinder 10, ensuring the stability and accuracy of the feeding process. When the first sliding plate 23 slides to the position of the second feeding mechanism 30, one end of the curved brim 1 will be clamped and fixed by the second feeding mechanism 30, thereby smoothly completing the feeding. By integrating the first sliding plate 23 and the first driving assembly 22, the feeding device 3 of the utility model realizes the automated feeding of the curved brim 1. This design not only improves the accuracy and efficiency of feeding, but also further reduces the dependence on worker proficiency. At the same time, the cooperative work of the first sliding plate 23 and the first driving assembly 22 makes the feeding process more stable and reliable, thereby ensuring the stability and consistency of the sewing quality.

[0045] Further, with reference to Figures 1 to 2 In some embodiments of the utility model, the first pressing assembly 21 further includes a first driving component 212, the output end of the first driving component 212 is connected to the first pressing component 211, and the first driving component 212 drives the first pressing assembly 21 to press the curved brim 1. According to the further optimized design of the utility model, the first pressing assembly 21 is additionally equipped with the first driving component 212 on the basis of the original first pressing component 211, to realize higher flexibility and controllability of the pressing operation of the curved brim 1. The first driving component 212 in the first pressing assembly 21 can be a pneumatic cylinder, an electric push rod, a hydraulic cylinder, or any driving mechanism capable of producing linear displacement. The output end of the first driving component 212 is closely connected to the first pressing component 211, and by controlling the start and stop of the first driving component 212, the lifting movement of the first pressing component 211 can be accurately regulated and controlled.

[0046] In actual application, when it is necessary to stably press the curved brim 1 against the surface of the support cylinder 10, the first driving component 212 only needs to be activated. Subsequently, the first driving component 212 will output driving force to drive the first pressing component 211 to descend, until it firmly presses the curved brim 1 against the support cylinder 10. This design ensures the stability of the curved brim 1 during sewing operation, effectively preventing deviation or shaking caused by external interference.

[0047] Further, with reference to Figures 1 to 2In some embodiments of the utility model, first compression part 211 still includes first compression piece 2111, first drive part 212 includes first drive piece 2121, first compression piece 2111 is arranged on the output end of first drive piece 2121, first drive piece 2121 drives first compression piece 2111 to move towards support cylinder 10, first compression piece 2111 abuts to curved brim 1, to make curved brim 1 tightly adhere to the outer surface of support cylinder 10.

[0048] According to the deep design of the utility model, first compression part 211 and first drive part 212 form a close cooperation in first compression assembly 21, aiming to ensure that curved brim 1 can be stably and accurately attached to the outer surface of support cylinder 10. First compression piece 2111 of first compression part 211 is usually made of materials with good rigidity and stability, such as metal or high-strength plastic. The shape and size of first compression piece 2111 will be customized according to the specific characteristics of curved brim 1 to ensure that pressure can be applied to it comprehensively and uniformly. First drive part 212 contains a first drive piece 2121 as the power source of the compression action. This first drive piece 2121 can be a cylinder, an electric push rod, a hydraulic cylinder or other linear drive equipment, and its output end is directly connected to first compression piece 2111. When first drive piece 2121 is activated, it will output driving force to push first compression piece 2111 to move towards support cylinder 10.

[0049] In actual operation, when curved brim 1 needs to be compressed to support cylinder 10, the control system will issue an instruction to first drive piece 2121. After receiving the instruction, first drive piece 2121 starts immediately, and through the driving force output by it, first compression piece 2111 moves along the preset path to approach support cylinder 10. As first compression piece 2111 gradually approaches, it will contact curved brim 1 and continuously apply pressure until curved brim 1 is tightly compressed on the outer surface of support cylinder 10. This design ensures the stability of curved brim 1 during sewing process, effectively preventing deviation or shaking caused by external force. At the same time, the close cooperation of first compression piece 2111 and first drive piece 2121 allows the compression force to be finely adjusted according to actual needs to adapt to curved brim 1 of different materials and thicknesses.

[0050] Similarly, further, Figures 1 to 2In some embodiments of the utility model, first compression part 211 includes second compression piece 2112, second compression piece 2112 is arranged at the both sides of first compression piece 2111, first drive part 212 still includes second drive piece 2122, second drive piece 2122 is connected with second compression piece 2112, and second drive piece 2122 is used to drive second compression piece 2112 to move towards support cylinder 10, and second compression piece 2112 abuts the both sides of curved brow hat brim 1 to make the both sides of curved brow hat brim 1 tightly adhere to the outer surface of support cylinder 10.

[0051] Specifically, according to the further optimization design of the utility model, first compression part 211 adds second compression piece 2112 on the basis of first compression piece 2111, and simultaneously, first drive part 212 also correspondingly increases second drive piece 2122 to realize the more comprehensive and stable compression of the both sides of curved brow hat brim 1. In addition to the original first compression piece 2111, first compression part 211 also contains two second compression pieces 2112. The two second compression pieces 2112 are arranged at the both sides of first compression piece 2111, and they are also made of materials with good rigidity and stability, such as metal or high-strength plastic. The shape and size of second compression piece 2112 can be adjusted according to the specific shape and size of curved brow hat brim 1 to ensure that it can closely fit the both sides of curved brow hat brim 1. In order to drive second compression piece 2112 to perform the compression operation, second drive piece 2122 is added in first drive part 212. Second drive piece 2122 is directly connected with second compression piece 2112, and it can be a linear drive device such as a pneumatic cylinder, an electric push rod or a hydraulic cylinder. When second drive piece 2122 is activated, it will output driving force to push second compression piece 2112 to move towards support cylinder 10.

[0052] In actual operation, when curved brow hat brim 1 needs to be compressed to support cylinder 10, the control system will simultaneously issue instructions to first drive piece 2121 and second drive piece 2122. After receiving the instructions, first drive piece 2121 is started to drive first compression piece 2111 to move towards support cylinder 10 and abut the middle part of curved brow hat brim 1; at the same time, second drive piece 2122 is also started to drive the two second compression pieces 2112 to move towards support cylinder 10 and abut the both sides of curved brow hat brim 1. Under the joint action of first compression piece 2111 and second compression piece 2112, curved brow hat brim 1 is comprehensively and uniformly compressed on the outer surface of support cylinder 10. This design not only ensures the stability of curved brow hat brim 1 during the sewing process, but also effectively prevents the deviation, shaking or warping caused by external force. At the same time, due to the close cooperation of first compression piece 2111, second compression piece 2112, first drive piece 2121 and second drive piece 2122, the compression force can be finely adjusted according to actual needs to adapt to curved brow hat brim 1 with different materials, thicknesses and shapes.

[0053] Referring to Figure 1 and Figure 2 In some embodiments of the present application, the first driving component 212 further comprises a third driving member 2123, which is connected with the first pressing component 211, and the output direction of the third driving member 2123 extends along the axial direction of the supporting cylinder 10, and the third driving member 2123 is used to drive the first pressing component 211 to move away from or close to the supporting cylinder 10, so as to enable the curved brim 1 to be placed in the clamped position of the supporting cylinder 10.

[0054] Specifically, according to another innovative design of the present application, the first driving component 212 not only contains a driving element for directly pressing the curved brim 1 in the first pressing assembly 21, but also adds a third driving member 2123 to realize the movement of the first pressing component 211 in the axial direction of the supporting cylinder 10, thereby facilitating the accurate placement of the curved brim 1 in the clamped position of the supporting cylinder 10. The third driving member 2123 is an important component newly added to the first driving component 212, which is connected with the first pressing component 211 and is responsible for driving the first pressing component 211 to move along the axial direction of the supporting cylinder 10. The third driving member 2123 can be a pneumatic cylinder, an electric push rod, a hydraulic cylinder or any driving device capable of generating linear displacement, and its output direction strictly extends along the axial direction of the supporting cylinder 10.

[0055] In actual operation, when it is necessary to place the curved brim 1 in the clamped position of the supporting cylinder 10, the control system will issue an instruction to the third driving member 2123. After receiving the instruction, the third driving member 2123 is immediately started to output a driving force to push the first pressing component 211 (including the first pressing member 2111 and possibly the second pressing member 2112) to move along the axial direction of the supporting cylinder 10 away from the initial position of the supporting cylinder 10. This movement provides sufficient space for the placement of the curved brim 1. Subsequently, the operator or the automated equipment can accurately place the curved brim 1 in the clamped position of the supporting cylinder 10. After the placement is completed, the control system again issues an instruction to the third driving member 2123, and the third driving member 2123 is reversely driven to move the first pressing component 211 towards the supporting cylinder 10 until the first pressing member 2111 (and the second pressing member 2112, if present) abuts and presses the curved brim 1, ensuring the stability of the curved brim 1 during the sewing process.

[0056] Referring to Figure 1 and Figure 3In some embodiments of the utility model, second feeding mechanism 30 includes: second slide plate 33, second compression assembly 31 and second drive assembly 32. Second slide plate 33 is attached to the outer surface of one end of support cylinder 10;Second compression assembly 31 is arranged on second slide plate 33, and second compression assembly 31 is used to compress curved brow brim 1, so that curved brow brim 1 is attached to the outer surface of support cylinder 10;Second drive assembly 32 is arranged at the end of support cylinder 10 away from first feeding mechanism 20, and the output end of second drive assembly 32 is connected to second slide plate 33, and second drive assembly 32 is used to drive second slide plate 33 to slide along the axis direction and the outer surface of support cylinder 10, so that second compression assembly 31 drives curved brow brim 1 to slide on the outer surface of support cylinder 10.

[0057] According to the overall design of the utility model, second feeding mechanism 30 as an important part of feeding device 3 undertakes the task of accurately sliding curved brow brim 1 on the outer surface of support cylinder 10. Second feeding mechanism 30 is mainly composed of second slide plate 33, second compression assembly 31 and second drive assembly 32, which cooperate together to ensure the stable conveying of curved brow brim 1 during sewing. Second slide plate 33 is the basic component of second feeding mechanism 30, which is closely attached to the outer surface of one end of support cylinder 10. The design of second slide plate 33 considers the fit and sliding property of the outer surface of support cylinder 10, and is usually made of wear-resistant and low-friction coefficient material to ensure smooth sliding and reduce wear. Second compression assembly 31 is arranged on second slide plate 33, and its main function is to compress curved brow brim 1 to tightly fit on the outer surface of support cylinder 10. Second compression assembly 31 can include compression parts and corresponding driving elements, and through the action of driving elements, compression parts can firmly press curved brow brim 1 to prevent deviation or falling during sliding. Second drive assembly 32 is the power source of second feeding mechanism 30, which is arranged inside support cylinder 10 and connected with second slide plate 33. The output end of second drive assembly 32 is directly connected to second slide plate 33, and through the output driving force, second slide plate 33 can slide along the axis direction and the outer surface of support cylinder 10. Second drive assembly 32 can be a motor-driven lead screw, cylinder, hydraulic cylinder and other linear driving devices, which can accurately control the moving distance and speed of second slide plate 33.

[0058] In actual operation, when it is necessary to slide the brim 1 on the outer surface of the support cylinder 10, the control system will issue an instruction to the second driving assembly 32. After receiving the instruction, the second driving assembly 32 is started, and an output driving force is generated to push the second sliding plate 33 (and the second pressing assembly 31 and the brim 1 thereon) to slide along the axis direction of the support cylinder 10. At the same time, the second pressing assembly 31 keeps the brim 1 pressed to ensure its stability during the sliding process. Through the close cooperation of the second sliding plate 33, the second pressing assembly 31 and the second driving assembly 32, the second feeding mechanism 30 can realize the precise sliding of the brim 1 on the outer surface of the support cylinder 10, providing stable and reliable feeding support for the subsequent sewing operation.

[0059] Further, with reference to Figure 1 and Figure 3 In some embodiments of the present application, the second pressing assembly 31 includes a second pressing component 311 and a second driving component 312, the second driving component 312 is arranged on the second sliding plate 33, and the second pressing component 311 is arranged on the output end of the second driving component 312. The second driving component 312 drives the second pressing component 311 to press the brim 1.

[0060] Specifically, according to the further refined design of the present application, the second pressing assembly 31, as a key part of the second feeding mechanism 30, is composed of a second pressing component 311 and a second driving component 312. They work together to realize the precise pressing of the brim 1, ensuring the stability and reliability during the feeding process. The second pressing component 311 is the part of the second pressing assembly 31 that directly acts on the brim 1. It is usually designed to have sufficient rigidity and stability to ensure that a stable pressure can be maintained during the pressing process. The shape and size of the second pressing component 311 will be customized according to the specific characteristics of the brim 1 to ensure that it can fully and uniformly cover and press the brim 1. The second driving component 312 is arranged on the second sliding plate 33, and it is the power source that drives the second pressing component 311 to perform the pressing action. The second driving component 312 can be a pneumatic cylinder, an electric push rod, a hydraulic cylinder or other linear driving devices. Its output end is connected to the second pressing component 311. When the second driving component 312 is activated, it will output a driving force to push the second pressing component 311 to move towards the brim 1 until it is tightly pressed on the outer surface of the support cylinder 10.

[0061] In actual operation, when it is necessary to press the curved brim 1 on the supporting cylinder 10, the control system will issue an instruction to the second driving component 312. Upon receiving the instruction, the second driving component 312 is immediately started to output a driving force to drive the second pressing component 311 to move along the preset path towards the curved brim 1. As the second pressing component 311 gradually approaches, it will contact the curved brim 1 and continuously apply pressure until the curved brim 1 is tightly pressed on the outer surface of the supporting cylinder 10. This design ensures the stability of the curved brim 1 during feeding and effectively prevents deviation or shaking due to external forces. At the same time, since the output force of the second driving component 312 can be finely adjusted according to actual needs, the second pressing assembly 31 can adapt to curved brims 1 of different materials, thicknesses, and shapes, providing wide applicability and flexibility.

[0062] Further, with reference to Figure 1 and Figure 3 In some embodiments of the present application, the second pressing component 311 includes two third pressing pieces 3111, and the second driving component 312 includes two fourth driving pieces 3121, the two third pressing pieces 3111 are respectively arranged on the output ends of the two fourth driving pieces 3121, and the two fourth driving pieces 3121 are oppositely arranged and located on both sides of the curved brim 1, and the fourth driving piece 3121 is used to drive the third pressing piece 3111 to abut against both sides of the curved brim 1.

[0063] Specifically, according to the further optimization of the present application, the second pressing component 311 adopts the design of two third pressing pieces 3111 in the second pressing assembly 31, and the second driving component 312 is correspondingly configured with two fourth driving pieces 3121. This design of bilateral pressing ensures that the curved brim 1 can receive more uniform and stable pressure during feeding, thereby improving the accuracy and overall efficiency of sewing. The two third pressing pieces 3111 contained in the second pressing component 311 are directly applied to the sides of the curved brim 1. These two third pressing pieces 3111 are respectively designed with contact surfaces matching the shapes of the two sides of the curved brim 1 to ensure that they can tightly fit and press the curved brim 1. The material selection of the third pressing piece 3111 also considers rigidity and stability to ensure that it will not deform or be damaged due to external forces during pressing. In order to drive the third pressing piece 3111 to perform the pressing operation, two fourth driving pieces 3121 are configured in the second driving component 312. These two fourth driving pieces 3121 are oppositely arranged and respectively located on both sides of the curved brim 1, and are connected to the corresponding third pressing pieces 3111. The fourth driving piece 3121 can be a linear driving device such as a pneumatic cylinder, an electric push rod, or a hydraulic cylinder, which can output sufficient driving force to push the third pressing piece 3111 towards the curved brim 1.

[0064] In actual operation, when it is necessary to press the curved brim 1 tightly on the support cylinder 10, the control system will simultaneously issue instructions to the two fourth driving members 3121. After receiving the instructions, the two fourth driving members 3121 are simultaneously started to drive the corresponding third pressing members 3111 to move to the two sides of the curved brim 1. With the gradual approach of the third pressing members 3111, they will simultaneously abut to the two sides of the curved brim 1 and continuously exert pressure until the curved brim 1 is tightly pressed on the outer surface of the support cylinder 10. This double-sided pressing design not only ensures the stability of the curved brim 1 during feeding, but also effectively prevents deviation or warping caused by single-sided pressing. At the same time, since the two fourth driving members 3121 can be independently controlled, the pressure on the two sides can be adjusted according to actual needs to adapt to curved brims 1 of different shapes and materials.

[0065] In some embodiments, similar to the first pressing member 211 in the first feeding mechanism 20, the second pressing member 311 can also include a fourth pressing member 3112; correspondingly, the second driving member 312 can also include a fifth driving member 3122, the fourth pressing member 3112 is arranged at the output end of the fifth driving member 3122, and the fourth pressing member 3112 and the fifth driving member 3122 are arranged between the two third pressing members 3111 and the two fourth driving members 3121. Therefore, it can be understood that the fourth pressing member 3112 and the fifth driving member 3122 are used to press the middle part of the curved brim 1, so that the curved brim 1 is attached to the outer surface of the support cylinder 10, which is conducive to the sliding of the curved brim 1 on the outer surface of the support cylinder 10 by the second feeding mechanism 30, thereby facilitating the sewing of the sewing mechanism 2 on the curved brim 1.

According to the above-mentioned first aspect embodiment, it can be understood that the sewing machine can replace manual feeding and avoid relying on the proficiency of manual operation, thereby improving the production efficiency and the quality of sewing. Further, the sewing machine can be provided with multiple feeding devices 3, and each feeding device 3 is configured with a corresponding sewing mechanism 2, so that a hat brim feeding device can also be arranged in the sewing machine, and the hat brim feeding device is used to sequentially provide the hat brim to the multiple feeding devices 3 and the sewing mechanism 2, thereby greatly improving the efficiency of hat brim production.

[0067] The utility model embodiment makes the detailed explanation in combination with the drawing, but the utility model is not limited to the above -mentioned embodiment, still can make various changes in the knowledge range that the person skilled in the art has possesses without departing from the utility model's tenet under the precondition that the utility model is not limited to the above -mentioned embodiment.
