[0002] During the gluing process of the glass fiber cloth, a feeding rack is required to feed the glass fiber cloth. Before using the feeding rack, the reel with the glass fiber cloth must be installed on the feeding rack.

[0003] The existing method of loading a roll of glass fiber cloth is usually to manually control a feed truck to transport the roll to the corresponding position on the feed rack, then manually control the jack on the feed truck to lift the roll, and then manually visually check whether the connecting holes at both ends of the roll are aligned with the connecting shaft of the feed rack.

The lifting mechanism includes a hydraulic cylinder 23 fixed to the top of the loading trolley 1, and the four corners of the top of the loading trolley 1 are fixedly connected to support columns 24. The top of the support column 24 is provided with a limiting hole 25. The bottom of the base plate 2 is fixedly connected to a limiting rod 26 that slides with the limiting hole 25. The output end of the hydraulic cylinder 23 is fixedly connected to the bottom of the base plate 2. The base plate 2 is driven to rise and fall by the hydraulic cylinder 23. The limiting hole 25 can limit the limiting rod 26, which can improve the stability of the lifting of the base plate 2.

[0027] A top plate 10 is provided on the top of the base plate 2, and two first bearing seats 11 arranged opposite to each other are fixedly connected to the top of the base plate 2. A first screw 12 is rotatably connected between the two first bearing seats 11, and a first motor 13 is fixedly connected to one of the first bearing seats 11.

[0028] The top of the top plate 10 is fixedly connected to a support frame, which includes two support plates 8 arranged opposite to each other. The top of the support plate 8 is provided with a positioning hole 9 for placing the reel 32. The two ends of the reel 32 can be placed in the two positioning holes 9 respectively; the positioning holes 9 are a triangular structure with a wide top and a narrow bottom, which can be used to place reels of different outer diameters, improving applicability, and the left and right sliding of the top plate 10 can drive the support frame to move left and right, thereby adjusting the distance between the connecting hole of the reel 32 and the connecting shaft 33 of the unwinding rack, which facilitates the docking of the connecting shaft 33 with the connecting hole;

When it is necessary to place reels 32 of different outer diameters on the support frame, since the inner diameter of the connecting hole of the reel 32 remains unchanged, different height differences will be generated between the connecting hole of the reel 32 and the connecting shaft 33 of the unloading rack. By adjusting the second sensing head 7 to slide up and down on the vertical plate 5, the height difference between the connecting hole and the connecting shaft 33 is offset, thereby greatly improving practicality.

[0031] Working principle:

[0032] like Figure 1-4As shown, when the automatic feeding device is in use, the reel 32 with the glass fiber cloth is placed on the support frame, and then the device is started, and the second motor 20 drives the second screw 19 to rotate, drives the second slider 21 to move back and forth, and then drives the feeding car 1 to move backward. After the first positioning sensor 3 on the feeding car 1 is aligned and sensed by the signal of the first sensing head 6, the first sensing head 6 will feed back the signal to the controller, and the controller will control the second motor 20 to stop, and then drive the bottom plate 2 to rise through the hydraulic cylinder 23. After the second positioning sensor 4 on the bottom plate 2 is aligned and sensed by the signal of the second sensing head 7, the second sensing head 7 will feed back the signal to the controller, and the controller will control the hydraulic cylinder 23 to stop, so that the connecting holes at both ends of the reel 32 on the support frame are aligned with the connecting shaft 33 of the unloading rack, and the material is automatically loaded, so that the loading of the reel 32 is completed in one step, thereby improving the loading efficiency of the glass fiber cloth.
