Description

Technical Field

[0001] This utility model relates to the field of embroidery eyelet equipment technology, specifically to a feeding structure for an embroidery eyelet sewing machine. Background Technology

[0002] In hat production, one step involves embroidering eyelets on the hat pieces, followed by stacking and sewing two embroidered pieces together—this is the eyelet sewing process. Currently, this process is largely done manually. Specifically, the operator places the hat pieces in the designated position on the eyelet sewing machine, aligns the two pieces, stacks them, and then places them under the sewing machine head for sewing. Manual operation is not only inefficient, but also prone to inconsistent product quality due to varying operator skill and attention to detail. Furthermore, the process requires operators to maintain a seated or standing posture, resulting in high labor intensity. Therefore, an automatic eyelet sewing machine is needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies and to disclose to the public a feeding structure for an embroidery stitching machine that has a reasonable structure, can improve production efficiency and product consistency, and reduce the labor intensity of workers.

[0004] The technical solution of this utility model is implemented as follows: A feeding structure for an eyelet sewing machine includes a frame on which an eyelet sewing machine and a sewing machine head are fixed. A feeding frame is provided on the frame, and a feeding conveying mechanism is provided between the feeding frame and the eyelet sewing machine. The feeding conveying mechanism includes a slide rail, and a feeding suction head that can move along the slide rail is provided on the slide rail. A transfer robot is provided between the eyelet sewing machine and the sewing machine head, and the transfer robot is rotatably mounted on the frame.

[0005] Further optimization measures for this technical solution are as follows: As an improvement, the feeding conveyor mechanism further includes a cable chain with a slider connected to it. The slider slides in engagement with the slide rail, and the feeding suction head is mounted on the slider. Driven by the cable chain and through the cooperation of the slider and the slide rail, the feeding suction head moves along the direction of the slide rail.

[0006] As an improvement, a lifting cylinder is provided on the slider, and the feeding suction head is fixed on the lifting cylinder. The lifting cylinder is used to raise and lower the feeding suction head.

[0007] As an improvement, the slider is provided with side plates on both sides of the lifting cylinder, and pressure heads are fixed on the side plates. When the feeding suction head descends to suck up material, it will cause the two ends of the cap to tilt up. The pressure heads are provided here to press down the cap, which can reduce the error rate of the feeding suction head picking up material.

[0008] As an improvement, the transfer robot includes a base that slides with a frame, a rotating seat is mounted on the base, and a mechanical gripper is fixed on the rotating seat. The rotating seat is driven by a motor, and the mechanical gripper rotates 180° by rotating the rotating seat.

[0009] As an improvement, the feeding frame is vertically equipped with several limiting posts on the outer periphery of the storage area. The limiting posts restrict the placement range of the cap piece.

[0010] As an improvement, the feeding frame is equipped with a lifting tray, and the lifting tray has an insertion rod at the corresponding embroidery eye position of the cap piece. When the cap piece is placed, the insertion rod is inserted into the embroidery eye, and with the limiting post, the placement of the cap piece can be more accurate, so as to ensure the quality of subsequent cap piece processing.

[0011] As an improvement, an empty material sensor is installed next to the feeding frame. When the caps in the feeding frame are used up, a signal (indicator light, prompt sound, etc.) is emitted to remind the operator to replenish the caps.

[0012] As an improvement, the feeding frame includes a first feeding frame and a second feeding frame arranged side by side along the slide rail direction of the feeding conveyor mechanism. During processing, sometimes two cap pieces are made from different raw materials; the first and second feeding frames facilitate the placement of cap pieces made from two different raw materials.

[0013] The advantages of this utility model compared with the prior art are: This utility model discloses a feeding structure for a embroidery eyelet sewing machine. The structure is rationally designed, using a feeding conveyor to transfer cap pieces from the feeding frame to the embroidery eyelet machine. Then, a 180° rotating transfer robot moves the cap pieces, now processed for embroidery eyelet sewing, to below the sewing machine head. This achieves automated feeding of the cap pieces for embroidery eyelet sewing, significantly improving production efficiency and reducing worker workload. Because the feeding process is mechanized and automated, consistency in feeding position is ensured each time, thereby improving product consistency and quality. Attached Figure Description

[0019] like Figures 1 to 6As shown, a feeding structure for a embroidery eyelet sewing machine includes a frame 1, on which an embroidery eyelet machine 2 and a sewing machine head 3 are fixed. A feeding frame 4 is provided on the frame 1, and a feeding conveying mechanism 5 is provided between the feeding frame 4 and the embroidery eyelet machine 2. The feeding conveying mechanism 5 includes a slide rail 51, and a feeding suction head 52 that can move along the slide rail 51 is provided on the slide rail 51. A transfer robot 6 is provided between the embroidery eyelet machine 2 and the sewing machine head 3, and the transfer robot 6 is rotatably mounted on the frame 1.

[0020] The feeding conveyor mechanism 5 also includes a drag chain 53, on which a slider 54 is connected. The slider 54 is slidably engaged with the slide rail 51, and the feeding suction head 52 is mounted on the slider 54.

[0021] The slider 54 is equipped with a lifting cylinder 55, and the feeding suction head 52 is fixed on the lifting cylinder 55.

[0022] The entire feeding conveyor mechanism 5 is driven by a drive device to move the drag chain 53, and the drag chain 53 drives the slider 54 to move laterally on the slide rail 51 (between the feeding frame 4 and the embroidery machine 2). The lifting cylinder 55 controls the lifting and lowering of the feeding suction head 52 to complete the picking and placing of the cap piece.

[0023] The slider 54 has side plates 54a on both sides of the lifting cylinder 55, and pressure heads 56 are fixed on the side plates 54a. When the feeding suction head 52 descends to suck up material, it will cause the two ends of the cap to tilt up. The pressure head 56 is set here to press down the cap, which can reduce the error rate of the feeding suction head 52 picking up material.

[0024] The transfer robot 6 includes a base 61 that slides with the frame 1. A rotating seat 62 is mounted on the base 61, and a mechanical gripper 63 is fixed on the rotating seat 62. The rotating seat 62 is driven to rotate by a rotary motor. Through the rotation of the rotating seat 62, the mechanical gripper 63 on it can rotate 180° in the plane, thereby realizing the transfer of the completed embroidered cap piece from the embroidery machine 2 to the sewing machine head 3.

[0025] The feeding frame 4 has several limiting posts 4a vertically arranged around the outer perimeter of the material storage area.

[0026] The feeding frame 4 is equipped with a lifting tray 4b, and the lifting tray 4b is equipped with a rod 4c at the corresponding embroidery eye position of the cap piece.

[0027] An empty material sensor 4d is installed next to the feeding frame 4.

[0028] Inside the feeding frame 4, the limiting post 4a restricts the placement of the cap pieces, and the positioning of the insertion rod 4c further improves the accuracy of the placement of the cap pieces to be processed. The empty material sensor 4d is set up to send a signal (indicator light, prompt sound, etc.) when the cap pieces in the feeding frame 4 are used up, reminding the operator to replenish the cap pieces.

[0029] The loading frame 4 includes a first loading frame 41 and a second loading frame 42 arranged side by side along the slide rail 51 of the loading conveying mechanism 5. During processing, sometimes the two cap pieces are made of different materials (different fabrics or different patterns). The first loading frame 41 and the second loading frame 42 are provided to facilitate the placement of cap pieces made of two different materials.

[0030] The working principle of the feeding structure of this embroidery eyelet sewing machine: The operator stacks the cap pieces to be processed and places them into the limiting post 4a of the feeding frame 4. During placement, the embroidery eyelets on the cap pieces pass through the insertion rod 4c on the lifting tray 4b. The equipment starts, and the lifting tray 4b rises as the number of cap pieces decreases. The feeding conveyor mechanism 5 operates, the slider 54 moves to the position of the first feeding frame 41, the feeding suction head 52 descends to pick up the top cap piece, the feeding suction head 52 rises, and the slider 54 moves to the position of the embroidery eye machine 2, placing the cap piece in the set position, where the embroidery eye machine 2 completes the embroidery work.

[0031] Next, the robotic arm 6 is transferred to work. The mechanical gripper 63 picks up the cap piece that has completed the embroidery process. The rotating base 62 rotates 180° so that the cap piece faces the sewing machine head 3. The base 61 moves towards the sewing machine head 3, and the mechanical gripper 63 places the cap piece in the set position below the sewing machine head 3. This completes the feeding process of one cap piece.

[0032] Next, the feeding conveyor 5 picks up the material from the second feeding frame 42 and transports it to the embroidery machine 2. After the embroidery machine 2 completes the embroidery work, the transfer robot 6 transfers it to the area below the sewing machine head 3 and places it on top of the previous cap piece, thus completing the feeding process for the two cap pieces. The sewing machine head 3 then sews the two cap pieces together, completing the sewing process.

[0033] This utility model discloses a feeding structure for a embroidery eyelet sewing machine. The structure is rationally designed and enables automated feeding throughout the entire embroidery eyelet sewing process, significantly improving production efficiency and reducing worker workload. Because the feeding process is mechanized and automated, consistency in feeding position is ensured each time, thereby improving product consistency and quality.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
