Description

Technical Field

[0001] This utility model relates to the field of cap sewing technology, specifically to a feeding mechanism for a cap sewing device. Background Technology

[0002] A hat is made by stitching together multiple pieces of fabric, each piece requiring two pieces of fabric placed side-by-side to be sewn together. Currently, the sewing of these pieces is mostly done manually. Workers take two pieces of fabric from a basket, stack them, and then sew them together using a sewing machine to complete the hat piece.

[0003] With rising labor costs leading to increased production costs, and due to variations in worker skills and proficiency, inconsistent hat panel production results in poor quality control. Manual sewing is costly, physically demanding, inefficient, and inconsistent; therefore, automated hat panel sewing equipment is needed. Utility Model Content

[0029] like Figures 1 to 5As shown, a feeding mechanism for a cap sewing device includes a frame 1. A pair of feeding frames 2 for storing fabric raw materials are provided on the frame 1. A lifting platform 21 is provided inside the feeding frame 2. A conveying mechanism 4 for conveying the fabric raw materials to a detection platform 3 is provided next to the feeding frame 2. A single-layer peeling mechanism is also provided next to the feeding frame 2. The single-layer peeling mechanism includes a rolling component 5 and a separation conveying component 6. The rolling component 5 is movably mounted on the frame 1. The rolling component 5 includes a rolling block 51 that is driven to rotate by a rolling drive mechanism. The bottom surface of the rolling block 51 is provided with a rolling curved surface 51a. The separation conveying component 6 includes a flat support plate 61 that is driven to move by a separation drive device.

[0030] The crushing block 51 is connected to a negative pressure device (the air pipe connected to the negative pressure device is not shown in the figure), and the crushing block 51 is provided with an adsorption hole 51b. While the crushing block 51 crushes the fabric material, the adsorption hole 51b uses negative pressure to adsorb the fabric material, so that one end of the top layer of fabric material can be more effectively lifted, facilitating the insertion of the flat support plate 61 of the separation conveying component 6, so as to achieve the purpose of separating the top layer of fabric material.

[0031] The rolling drive mechanism includes a first cylinder 52, a cam 53 connected to the first cylinder 52, a rotating shaft 54 ​​connected to the cam 53, and the rolling block 51 fixed to the rotating shaft 54.

[0032] The frame 1 is equipped with a translation cylinder 71, on which a compaction assembly bracket 72 is fixed. A first vertical cylinder 73 is mounted on the compaction assembly bracket 72, and a mounting base 74 is mounted on the first vertical cylinder 73. The first cylinder 52 is mounted on the mounting base 74, and the rotating shaft 54 ​​is rotatably engaged with the mounting base 74. The upper end of the first cylinder 52 is hinged to the mounting base 74. The first cylinder 52 drives the cam 53 to rotate, which in turn drives the rotating shaft 54 ​​to rotate, thereby causing the compaction block 51 to rotate. The translation cylinder 71 drives the entire compaction assembly 5 to move horizontally, while the first vertical cylinder 73 drives the lifting and lowering of the compaction assembly 5.

[0033] The separation drive device is a second cylinder 62, the bottom of the flat support plate 61 is fixed with a slider 63, the frame 1 is fixed with a slider guide rail 64, and the slider 63 slides in cooperation with the corresponding slider guide rail 64.

[0034] The conveying mechanism 4 includes a base 41, a horizontal slide rail 42 on the base 41, a slide block 43 on the horizontal slide rail 42, a second vertical cylinder 44 fixed on the slide block 43, and an adsorption head 45 mounted on the second vertical cylinder 44. In this embodiment, the slide block 43 is driven to move by the cylinder. Through the cooperation of the slide block 43 and the second vertical cylinder 44, the adsorption head 45 can move in space.

[0035] The horizontal slide rail 42 is provided with slide guide rails 46 on both sides, and the slide 43 slides in cooperation with the slide guide rails 46. The slide guide rails 46 make the movement of the slide 43 smoother.

[0036] The second vertical cylinder 44 is equipped with an adsorption head bracket 45a, and the adsorption heads 45 are fixed side-by-side on the adsorption head bracket 45a. The adsorption head bracket 45a facilitates the fixation of the adsorption heads 45.

[0037] The bottom of the frame 1 is equipped with lockable rollers 11. The rollers 11 facilitate the overall movement of the cap sewing device, and can be locked after the device is in position.

[0038] Working principle:

[0039] The cap sewing device of this utility model uses two pieces of fabric material to be fed simultaneously. Two stacks of multi-layered fabric material are placed on the lifting platform 21 of the corresponding feeding frame 2. The lifting platform 21 gradually rises to transport the fabric material upwards. Since only the top layer of fabric material needs to be taken each time it is fed, the top layer of fabric material needs to be peeled off, thereby achieving the purpose of feeding one piece at a time.

[0040] The feeding mechanism of the cap sewing device of this utility model is equipped with a single-layer peeling mechanism, which peels off the top layer of fabric material through the cooperation of the crushing component 5 and the separating conveying component 6. The specific process is as follows: Through the cooperation of the translation cylinder 71 and the first vertical cylinder 73, the crushing block 51 is moved above the feeding frame 2. While the crushing block 51 is descending, the first cylinder 52 drives the rotating shaft 54 ​​to rotate through the cam 53, which in turn drives the crushing block 51 to rotate, so that the crushing block 51 rotates and crushes the fabric material, causing the top layer of fabric material near the separating conveying component 6 to be lifted up. At the same time, the suction holes 51b on the crushing block 51 use negative pressure to absorb the lifted fabric material. Then, the second cylinder 62 drives the flat support plate 61 to move and insert below the top layer of fabric material, thereby peeling off the top layer of fabric material. At this time, the negative pressure device is turned off, and the top layer of fabric material will be laid flat on the flat support plate 61.

[0041] Next, the conveying mechanism 4 operates, driving the suction head 45 to move through the cooperation of the slide 43 and the second vertical cylinder 44. The suction head 45 transfers the fabric material on the flat support plate 61 to the detection platform 3 (next process), completing the simultaneous feeding of two pieces of fabric material. While the conveying mechanism 4 is operating, the crushing assembly 5 exits the conveying line, and the separation conveying assembly 6 resets.

[0042] By repeating this process, the fabric raw materials can be automatically fed piece by piece, freeing up labor and improving processing efficiency.

[0043] 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.
