[0026] Working principle: Leather is the skin of livestock, wild animals or reptiles, which is a cortical material obtained after processing such as depilation and tanning. It is usually used to make products such as clothing, shoes, furniture and car seats. At the same time, in order to ensure the beauty of the products, a carving device is required to carve patterns on the leather surface. The existing carving device does not fix the leather during the transportation process, which makes the leather easily deformed by heat during the carving process, resulting in a decrease in the carving quality of the leather. In order to solve this problem, a fixing mechanism and an adjusting mechanism are set, and the turntable 16 is rotated so that it pushes the threaded rod 15 to move telescopically inside the support plate 1 during rotation, so that with the cooperation of the sliding rod 14, the movable frame 2 is pushed to move horizontally inside the support plate 1, thereby changing the distance between the movable frames 2 on both sides so that it can be suitable for leather of the current size. At this time, the leather is placed between the conveyor belt 8 and the shell 4, and the spring 5 pushes the shell The body 4 moves downward, so that the roller 6 inside the shell 4 contacts the leather, and with the cooperation of the protrusion 7, the edge of the leather is squeezed and buckled on the inside of the card slot 9 to fix the edge of the leather. Then the servo motor 10 is controlled to drive the output end drive roller 11 to rotate, thereby driving the conveyor belt 8 to move with the cooperation of the driven roller 12. At the same time, the flat plate 13 can support the conveyor belt 8, thereby transporting the leather on the surface of the conveyor belt 8 to the inside of the carving room 17 for carving. During the processing, the exhaust fan 18 is turned on to allow air to circulate inside the carving room 17, and with the cooperation of the filter 19, harmful substances are filtered out. At the same time, the door curtain 20 can prevent harmful gas leakage. After that, the servo motor 10 is continued to be controlled to drive the conveyor belt 8 to move, and the carved leather is moved out of the inside of the carving room 17 to complete the carving of the leather, thereby solving the problem that the carving quality of the leather is reduced due to position offset.
