DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] A typical implementation of the present utility model is as follows Figure 1 As shown, a pipe cutting and unloading device comprises a blanking rack 1, which is placed at the rear end of a laser cutting machine and is used to receive the finished pipe after cutting. A receiving plate 2 is arranged on one side of the blanking rack 1, and the finished pipe after cutting falls onto the receiving plate 2 and falls onto the blanking rack 1 through the receiving plate 2. A waste opening is arranged at one end of the receiving plate 2, and a waste cart is placed below the waste opening. The waste after cutting falls into the waste cart from the waste opening. A folding plate 3 is arranged at the waste opening at one end of the receiving plate 2, and the folding plate 3 is rotatably connected to the receiving plate 2 through a hinge. A fixing plate 5 is arranged at one end of the bottom surface of the receiving plate 2 close to the folding plate 3, and the fixing plate 5 A first cylinder 4 is arranged perpendicular to the receiving plate 2, between the fixed plate 5 and the folding plate 3. The first cylinder 4 is arranged obliquely, and its fixed end is rotatably connected to the bottom end of the fixed plate 5, and the telescopic end is rotatably connected to the folding plate 3. The folding plate 3 is driven to rotate around the hinge by the first cylinder 4. When the telescopic end of the first cylinder 4 is extended, the upper surface of the folding plate 3 is flush with the upper surface of the receiving plate 2, so that short-length pipes (less than 200mm in length) can fall directly onto the finished product blanking rack. When the telescopic end of the first cylinder 4 is shortened, the folding plate 3 flips down. At this time, the waste opening at the end of the receiving plate 2 is opened, so that the waste can fall into the waste cart from the waste opening.

[0026] A lifting device and a flipping device are provided below the receiving plate 2, which can drive the receiving plate 2 to lift and flip the receiving plate 2, making it convenient for pipe unloading.

[0027] Specifically, Figure 2As shown, the lifting device includes a fixed seat 9, one side of which is connected to the blanking rack 1 and fixed to the blanking rack 1 by bolts, and the fixed seat 9 is slidably connected to a lifting base 10 on the side away from the blanking rack 1, and a guide rail slider mechanism is arranged between the lifting base 10 and the fixed seat 9. The guide rail slider mechanism is a common guide rail slider mechanism on the market, wherein two guide rails are provided, and the two guide rails are fixed in parallel to the lifting base 10, and sliders are slidably connected to the guide rails, and the sliders are fixedly connected to the fixed seat 9, thereby realizing a sliding connection between the fixed seat 9 and the lifting base 10, and the two guide rails are arranged vertically, and the lifting base 10 can perform lifting and lowering movements along the guide rails.

[0028] A driving motor is also fixed to the side of the fixed seat 9 away from the blanking rack 1, and a gear 6 is fixedly connected to the output shaft of the driving motor. A rack 7 is arranged at the position corresponding to the gear 6 on the inner wall of the lifting base 10. The rack 7 is arranged parallel to the two guide rails, and the gear 6 is meshed with the rack 7. When the driving motor rotates, the gear 6 and the rack 7 are used to drive the lifting base 10 to achieve lifting.

[0029] Both sides of the lifting base 10 are provided with a turning device, and the lifting base 10 is connected to the receiving plate 2 through the turning device. Figure 3 As shown, the flipping device includes a first support rod 8, which is fixed to the top of the side of the lifting base 10, and is located on the side of the top of the side of the lifting base 10 close to the fixed seat 9. The top of the first support rod 8 is rotatably connected to one side of the bottom surface of the receiving plate 2, and the other side of the bottom surface of the receiving plate 2 is rotatably connected to the second support rod 11. The second support rod 11 is connected to the second cylinder 15 through a connecting block 13 and a slide rail 14. Specifically, a second cylinder 15 is also provided on the side of the lifting base 10, and a slide rail 14 is provided above the second cylinder 15. The second cylinder 15 and the slide rail 14 are both vertically arranged A connecting block 13 is slidably connected to the slide rail 14, and a connecting plate 12 is fixed to the connecting block 13. The telescopic end of the second cylinder 15 is connected to the bottom of the connecting plate 12, and the end of the second support rod 11 away from the receiving plate 2 is rotatably connected to the top of the connecting plate 12. When the telescopic end of the second cylinder 15 drives the connecting block 13 to slide along the slide rail 14, the connecting block 13 drives the side connected to the receiving plate 2 to move up and down through the second support rod 11. Since the height of the first support rod 8 remains unchanged, the second cylinder 15 is used to realize the inclination of the upper surface of the receiving plate 2, which is convenient for quick unloading.

[0030] By setting a lifting device and a turning device, the lifting device is used to increase the height of the receiving plate, and the turning device is used to tilt the receiving plate to one side, so that the finished pipes that fall onto the receiving plate can quickly fall onto the blanking rack through the inclined receiving plate, thereby improving the efficiency of pipe unloading.

[0031] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
