[0014] 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.

[0015] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic flat material feeding device, including a base 1, a pressing device and a pulling device. The pressing device includes a pressing bracket 2, a threaded cylinder 3 and a fixed pressure plate 4. The pressing bracket 2 is installed on the top of the base 1, the threaded cylinder 3 is installed on the pressing bracket 2, and the fixed pressure plate 4 is installed on the telescopic shaft of the threaded cylinder 3. The pressing device is used to fix the material during laser processing. The movement of the threaded cylinder 3 drives the fixed pressure plate 4 to move, thereby pressing the material to be processed onto the base 1. The material pulling device includes a guide rail 5, a sliding frame 6, a material pulling cylinder 7, an upper pressure cylinder 8, and an upper pressure plate 9. Two guide rails 5 are provided, installed on one side of the base 1. The sliding frame 6 is movably installed on the guide rails 5, allowing it to slide. The material pulling cylinder 7 is installed on the base 1, and its telescopic shaft is fixedly connected to the sliding frame 6. Movement of the telescopic shaft of the material pulling cylinder 7 drives the sliding frame 6 to move. The upper pressure cylinder 8 is installed on the sliding frame 6, and the upper pressure plate 9 is installed on the telescopic shaft of the upper pressure cylinder 8. The material pulling device is used to feed material forward. Movement of the upper pressure cylinder 8 drives movement of the upper pressure plate 9, thereby pressing the material to be processed between the upper pressure plate 9 and the sliding frame 6. The material pulling cylinder 7 drives the entire sliding frame 6 to move, thus moving the material.

[0016] A mounting groove 10 is provided on the base 1, and a feeding hole 11 is provided below the mounting groove 10. The processed and laser-cut material falls from the feeding hole 11 into the receiving frame. A positioning template 12 for fixing the material is placed in the mounting groove 10. The positioning template 12 is fixed in the mounting groove 10 by bolts. A set of positioning grooves 13 are opened on the positioning template 12. When the long strip of flat material is fed into the base 1, it is fed into the positioning groove 13 (e.g., ...). Figure 5 (As shown); the positioning template 12 adopts a replaceable design, and the shape and size of the positioning groove 13 are designed according to the needs; the number of positioning grooves 13 is designed to be multiple, so that multiple sets of materials can be fed and laser processed at the same time; a set of fixing holes 16 are provided on the mounting groove 10, so that the positioning template 12 can be easily replaced in the mounting groove 10, and other shapes of tooling fixtures can also be installed.

[0017] The sliding frame 6 is also equipped with a buffer plate 14. The buffer plate 14 is made of a material with a certain deformation force. The buffer plate 14 and the upper pressure plate 9 together fix the material to accommodate slight errors in the raw material.

[0018] A limiting baffle 15 is provided on the guide rail 5. The limiting baffle 15 is fixed to the guide rail 5 by bolts, so that the position of the limiting baffle 15 on the guide rail 5 can be adjusted, thereby limiting the upper limit of the extension of the material pulling cylinder 7 according to the needs of the processed raw materials.

[0019] In use: First, the long strip of flat material is inserted into the upper pressure plate 9. The upper pressure cylinder 8 drives the upper pressure plate 9 to move and fix the flat material. Then, the pulling cylinder 7 retracts and conveys the flat material to the positioning template 12 on the base 1. The positioning groove 13 plays a role in accurately positioning the flat material. Then, the threaded cylinder 3 moves to fix the flat material on the base 1. Finally, laser processing is performed. After processing, the cut material falls from the feeding hole 11. The upper pressure cylinder 8 is released first, the pulling cylinder 7 extends, the upper pressure cylinder 8 fixes the material, the upper pressure cylinder 8 is released, and the pulling cylinder 7 retracts to convey the flat material to the base 1 again. This cycle is repeated to achieve continuous feeding and processing. When the long strip of flat material is finished, the next material is manually put in.
