It accurately controls the cutting process through the computer numerical control system, has the advantages of high efficiency and high precision, and can greatly improve production efficiency and product quality. Especially when processing columnar materials, CNC cutting machines need to perform precise positioning and cutting. In order to ensure the automation of production and improve work efficiency, CNC cutting machines usually need to be equipped with automatic feeding devices. This device can automatically feed columnar materials into the cutting machine and ensure the stability and positioning accuracy of the materials, thereby reducing the risk of manual operation, improving production efficiency, and ensuring the continuity and stability of the processing process.

[0003] At present, the existing automatic feeding devices of CNC cutting machines usually use conveyor belts, robotic arms or rollers to transport columnar materials to the cutting machine. The conveyor belt can stably transport the materials to the working area, and the robotic arm can accurately position the materials. However, most of these devices feed materials continuously, which will cause material accumulation and affect the stability and efficiency of production. Therefore, an automatic feeding device for CNC cutting machine is proposed to solve the above problems. Utility Model Content

A moving arm 9 is slidably connected to the side wall of the slide rail 8, and a push block 10 is slidably connected to the side wall of the moving arm 9. A connecting shaft 11 is arranged inside the push block 10, and one end of the connecting shaft 11 is arranged inside the rotating frame 7 and slidably connected to the inside of the slide plate 6. The shape of the slide groove inside the slide plate 6 is square. When the rotating frame 7 is rotated to a vertical state, it plays the effect of supporting the connecting shaft 11, and also plays the effect of guiding the movement of the connecting shaft 11. The push blocks 10 are all fixedly connected to the bottom of the moving frame 3;

[0031] When the material is in the first position, the movable frame 3 is in the first position, and the material in the material receiving frame 13 is in the first position, and the material in the material receiving frame 13 is in the second ... When the lever 11 is in the downward direction, the lever 12 is in the forward direction, and the lever 12 is in the forward direction, so that the lever 12 can be moved back and forth, thereby the lever 12 is in the forward direction, and the lever 12 is in the forward direction, so that the lever 12 can be moved back and forth, thereby the lever 12 can be moved back and forth, thereby the lever 12 can be moved back and forth, thereby the lever 12 can be moved back and forth,

[0032] Reference Figure 4 The discharging mechanism includes a mounting frame 12, a material receiving frame 13 is fixedly connected to the bottom of the mounting frame 12, the material receiving frame 13 is fixedly connected to the side wall of the fixing frame 2, a material storage box 14 is fixedly connected to the top of the mounting frame 12, a discharging trough 18 is opened inside the material storage box 14, a fixing plate 15 is arranged between the discharging trough 18 and the bottom end of the material storage box 14, and is fixedly connected to the top of the mounting frame 12, a material discharge barrel 16 is rotatably connected between the fixing plates 15, and the material discharge barrel 16 is arranged at the top of the discharging trough 18, a motor 17 is fixedly connected to the side wall of one side fixing plate 15, and the output end of the motor 17 is fixedly connected to one end of the material discharge barrel 16, a support column 20 is fixedly connected to the top of the bottom of the mounting frame 12, and the bottom end of the support column 20 is fixedly connected to the top of the bottom plate 1, and a baffle 19 is fixedly connected to the top of the mounting frame 12, and the baffle 19 is arranged outside the discharging trough 18 to prevent the material from falling off from the top of the mounting frame 12 and failing to fall into the inside of the material receiving frame 13.

[0033] When using the equipment, first place the columnar raw material in the storage box 14. Since the storage box 14 has an arc-shaped shape, the raw material inside it will automatically slide downward and fall into the interior of the discharge barrel 16. Then start the motor 17 to drive the discharge barrel 16 to rotate. When the opening of the discharge barrel 16 is facing downward, the material in the barrel will naturally fall and fall into the receiving frame 13 through the discharge chute 18. Through the continuous rotation of the discharge barrel 16, continuous transportation of the material can be achieved. When the material in the discharge barrel 16 is emptied, the material in the storage box 14 will be automatically replenished into the discharge barrel 16 to ensure the continuous discharge of the material, ensure the continuity and stability of the discharge, and effectively avoid stagnation problems caused by material accumulation or blockage.

[0034] Working principle: When the device is used, first place the columnar raw material inside the storage box 14. At this time, due to the curvature of the storage box 14 itself, the raw material at the bottom will slide downward and fall into the lower barrel 16. At this time, the motor 17 is started to drive the lower barrel 16 to rotate. As the lower barrel 16 rotates, when the opening of the lower barrel 16 is facing downward, the material inside the lower barrel 16 will fall downward and fall into the receiving frame 13 through the discharge chute 18. After the lower barrel 16 is emptied, as it continues to rotate, the material at the bottom of the storage box 14 will continue to fall into the lower barrel 16, thereby achieving a continuous discharge effect.

[0035] When the material falls into the receiving frame 13, the double-headed motor 5 is started to drive the rotating frame 7 to rotate. As the rotating frame 7 rotates, the connecting shaft 11 is further driven to move, and one side of the connecting shaft 11 slides inside the chute plate 6 from bottom to top, and the push block 10 is driven to move upward, and synchronously slides on the moving arm 9, thereby lifting the moving frame 3 upward, and lifting the material in the receiving frame 13 through the internal card slot. As the rotating frame 7 continues to rotate, when the connecting shaft 11 moves horizontally from right to left inside the chute plate 6, the push block 10 is synchronously moved, thereby The movable arm 9 is pushed to slide forward on the slide rail 8, and the movable frame 3 moves forward the distance of a slot. When the connecting shaft 11 moves from top to bottom inside the slide plate 6, the push block 10 moves downward on the movable arm 9, so that the movable frame 3 follows the downward movement, and the material inside the movable frame 3 stays in the slot in the current fixed frame 2. When the connecting shaft 11 moves from left to right in the slide plate 6, the push block 10 will be pulled backward to complete the resetting of the movable frame 3. As the slide plate 6 continues to rotate, the movable frame 3 will continue to transport the material on the fixed frame 2 and the material receiving frame 13 forward, thereby achieving the effect of intermittent feeding.
