[0016] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0017] Example 1, as Figure 1-2 As shown, a combined automatic feeding mechanism includes a feeding platform 1, a gantry frame 2 is installed above the feeding platform 1, a screw slide 3 is installed on the upper wall of the inner cavity of the gantry frame 2, a slide seat 4 is slidably connected to the outer surface of the screw slide 3, a first sliding frame 5 is fixedly installed below the slide seat 4, a second sliding frame 6 is provided below the first sliding frame 5, a sliding plate 22 is fixedly connected above the second sliding frame 6, sliders 8 are fixedly installed on the left and right sides of the lower surface of the sliding plate 22, slide rails 7 are fixedly installed on the left and right sides of the first sliding frame 5, and the second sliding frame 6 is slidably connected to the slide rails 7 through the sliders 8; a positioning plate 9 is fixedly installed below the first sliding frame 5, a telescopic motor 10 is fixedly installed on the second sliding frame 6, the telescopic shaft end of the telescopic motor 10 is connected to the positioning plate 9, a material receiving tray 21 is fixedly installed on the upper surface of the sliding plate 22; a needle clamp cylinder 11 is installed below the second sliding frame 6;

[0018] A lifting electric cylinder 12 is installed in the feeding platform 1. The movable rod of the lifting electric cylinder 12 passes through the upper surface of the feeding platform 1 and is connected to the lifting platform 13. The upper surface of the lifting platform 13 is used to place a fabric tray 14.

[0019] Working principle:

[0020] When in use, the operator first places a batch of fabrics on the fabric tray 14, and then places the fabric tray 14 on the lifting platform 13, and then controls the movable rod of the lifting electric cylinder 12 to drive the entire lifting platform 13 to a predetermined height, so that the top layer of fabric on the fabric tray 14 corresponds to the needle clamp cylinder 11 under the second sliding frame 6; then controls the needle clamp cylinder 11 to clamp the top layer of fabric, and then controls the lifting electric cylinder 12 to drive the entire lifting platform 13 down to its initial position.

[0021] Afterwards, the screw slide 3 is controlled to operate, so as to drive the first sliding frame 5 to extend forward through the slide 4, so that the entire first sliding frame 5, the second sliding frame 6 and the needle clamp cylinder 11 can be moved to the first work station, and then the telescopic shaft of the telescopic motor 10 is controlled to extend, thereby driving the entire second sliding frame 6 and the needle clamp cylinder 11 to extend forward again, so that the needle clamp cylinder 11 and the receiving tray 21 can be moved to the second work station. At this time, the needle clamp cylinder 11 is exactly opposite to the position of the lower mold base. At this time, the fabric can be released by controlling the needle clamp cylinder 11, so that the fabric automatically falls into the mold cavity of the lower mold base; at the same time, the product with the composite hemming completed in the upper mold base can be released, so that the product with the composite hemming completed automatically falls onto the receiving tray 21. Afterwards, the telescopic shaft of the telescopic motor 10 is controlled to retract to its initial position, causing the entire second sliding frame 6 to return to the first station. At this time, the hemmed products on the receiving tray 21 can be manually removed. The screw slide 3 is then controlled to drive the slide 4 back to its initial position, which in turn causes the first sliding frame 5 to return to its initial position. The above steps are then repeated in this cycle, thereby automating the handrail hemming loading process, greatly improving production efficiency and reducing labor intensity, with significant technical and economic benefits.

[0022] In this embodiment, the screw slide 3, telescopic motor 10, needle clamp cylinder 11 and lifting electric cylinder 12 all adopt well-known technical solutions in the prior art, which are already understood by those skilled in the art and will not be described in detail here.

[0023] In Example 2, as a further preferred embodiment of Example 1, mutually parallel guide rail frames 15 are mounted on both left and right sides of the upper wall of the inner cavity of the gantry frame 2. Guide rails 16 are fixedly mounted below the guide rail frames 15. Sliding blocks 17 are fixedly mounted on both sides of the upper surface of the first sliding frame 5. The sliding blocks 17 are slidably connected to the guide rails 16. The provision of the guide rail frames 15 and the guide rails 16 enables the first sliding frame 5 to slide in cooperation with the guide rails 16 through the sliding blocks 17, thereby effectively ensuring the stability of the first sliding frame 5 during the forward and backward sliding process.

[0024] Example 3, as a further preferred embodiment of Example 2, has L-shaped limit plates 18 fixedly mounted on both the left and right sides of the first sliding frame 5. The two L-shaped limit plates 18 are located on the left and right sides of the guide rail frame 15, respectively. The inner sides of the two L-shaped limit plates 18 are rotatably connected to a plurality of rollers 19 via a rotating shaft. The rollers 19 are in contact with the upper surface of the guide rail frame 15. The L-shaped limit plates 18 can limit the left and right position of the first sliding frame 5, effectively preventing the first sliding frame 5 from shifting. Moreover, by arranging the rollers 19 on the inner sides of the L-shaped limit plates 18, the rollers 19 can provide a certain degree of support for the first sliding frame 5.

[0025] Embodiment 4, as a further preferred embodiment of embodiment 1, an auxiliary positioning column 20 is provided on the fabric tray 14. The auxiliary positioning column 20 can achieve the positioning effect of the fabric, so that batches of fabrics can be accurately positioned by the auxiliary positioning column 20 and the fabric tray 14.

[0026] In the present invention, a controller can be provided on the front side of the gantry frame 2, and the signal output end of the controller is connected to the signal input ends of the screw slide 3, the telescopic motor 10, the needle clamp cylinder 11, and the lifting cylinder 12. Thus, the PLC control chip in the controller can realize the drive control of the screw slide 3, the telescopic motor 10, the needle clamp cylinder 11, and the lifting cylinder 12, thereby achieving an automated control effect.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
