[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the present invention, an automatic feeding machine includes a fabric cutting frame 1. A transmission sprocket 18 is rotatably mounted on one end of the fabric cutting frame 1 via a transmission shaft 17. A longitudinal cutter 4 is mounted between the two transmission sprockets 18 via a transmission chain 19 and a mounting bracket 20. One end of the transmission shaft 17 is connected to a motor 22 via a gear set 21. The motor 22 is fixedly mounted on the inner wall of the fabric cutting frame 1 via a base. Two sets of parallel transmission sprockets 18 and transmission chains 19 are arranged on the transmission shaft 17. Limiting plates are also provided on both sides of the transmission sprockets 18, allowing the motor 22 and gear set 21 to drive the transmission sprockets 18 and transmission chains 19 to rotate and adjust, thereby adjusting the height of the longitudinal cutter 4. The longitudinal cutter 4 slides through the cutting end face of the fabric cutting frame 1 for fabric cutting. The other end of the frame 1 is equipped with a lifting bracket 7 via a lead screw 13. The inner wall of the fabric cutting frame 1 is also equipped with a guide rail 14, and the lifting bracket 7 is also equipped with a guide slider 15 that slides with the guide rail 14. The two ends of the lifting bracket 7 are rotatably equipped with fabric positioning plates 9 via a first connecting frame 16 and a connecting shaft 8. The fabric positioning plate 9 is equipped with multiple fabric clamps on one side, which facilitates the horizontal clamping and fixing of one end of the fabric to be cut. The clamping and fixing stability is high, and the operation is convenient and quick. The lifting bracket 7 and the fabric positioning plate 9 are connected by a second connecting frame 24, which is equipped with a first cylinder 23 for adjusting the fabric positioning plate 9 by 90 degrees. This facilitates the setting of the fixed fabric end parallel to the side of the fabric cutting frame 1, and facilitates the cutting of the fixed end face of the fabric by using the vertical cutting blade 4 with lifting adjustment.

[0022] like Figure 1As shown, in order to prevent the fabric from moving during cutting and to improve the cutting accuracy, a fabric adsorption assembly is also provided on one side of the fabric cutting machine frame 1. The fabric adsorption assembly includes an adsorption plate 2 set at one end of the fabric cutting machine frame 1. The adsorption plate 2 has multiple negative pressure adsorption holes 3 on one side, and the adsorption plate 2 is symmetrically arranged with two sets of longitudinal cutting blades 4 inside the fabric cutting machine frame 1. The lower side of the adsorption plate 2 is connected to a negative pressure fan 6 through a pipe 5, so that the negative pressure fan 6 and the pipe 5 can perform air suction treatment on the negative pressure adsorption holes 3 on one side of the adsorption plate 2. When the fabric is longitudinally set on one side of the fabric cutting machine frame 1, it is tightly set against the end faces on both sides of the cutting edge under the action of negative pressure, realizing the longitudinal clamping and positioning of the fabric, preventing the fabric from moving during cutting, improving the cutting accuracy, and making unloading convenient and quick.

[0023] like Figure 1 and Figure 3 As shown, in order to laterally clamp and fix one end of the fabric to be cut, the fabric clamp also includes a second cylinder 11 set on one side of the fabric positioning plate 9 via the upper bracket 10, and a clamping plate 12 is provided at the lower end of the second cylinder 11, so that multiple clamping plates 12 can be driven to move down by multiple second cylinders 11, which can laterally clamp and fix one end of the fabric to be cut. The clamping and fixing stability is high and the operation is convenient and quick. The clamping end face of the fabric positioning plate 9 is also provided with a groove 25 for longitudinal cutting, which makes it easy for the longitudinal cutting knife 4 to longitudinally cut the fabric fixed on one side of the fabric positioning plate 9 through the groove 25.

[0024] The working principle and usage process of this utility model are as follows: When in use, connect the external power supply, place one end of the curtain fabric to be cut horizontally on the fabric positioning plate 9, and then use multiple fabric clamps on one side of the fabric positioning plate 9 to clamp and fix one end of the curtain fabric horizontally. Then, the first cylinder 23 drives the fabric positioning plate 9 and the fabric to rotate 90 degrees towards the side of the fabric cutting machine frame 1. Then, the lead screw 13 drives the lifting bracket 7, the fabric positioning plate 9 and the fabric to be cut to move vertically upward into place, and the upward movement height of the fabric is always less than the height of the longitudinal cutter 4. Then, the fabric adsorption component adsorbs the curtain fabric tightly against the cutting end face. Finally, the motor 22 and the sprocket group drive the lower side of the longitudinal cutter 4 to cut the curtain fabric. After the cutting is completed, the longitudinal cutter 4 moves upward to reset, and the fabric positioning plate 9 moves downward to flip and reset, completing a single cutting and cutting. Moreover, the operation is convenient and quick, the cut is relatively flat, and the cutting and cutting accuracy is high. After manual feeding, the longitudinal clamping and cutting of the fabric can be realized, and the degree of automation is high.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
