[0031] To solve the technical problems in the background art, as Figure 1-2 shown, the present application provides a technical solution: an intermittent pipe feeding device, characterized as follows:

[0032] The workbench 1 is horizontally arranged and used to support the whole device. The material box 2 is an open box body, having a first side plate 3, a bottom plate 5 and two symmetrical second side plates 4. A blanking port 6 is arranged on one side of the material box 2, and the material box 2 has an included angle with the horizontal direction. The horizontal position of the blanking port 6 is lower than the horizontal position of the first side plate 3 symmetric to it. The material box 2 is fixed on the workbench 1. The bottom plate 5 of the material box 2 is used to carry the pipe materials. The two symmetrical second side plates 4 of the material box 2, together with the first side plate 3 and the bottom plate 5, form the structure of the material box 2. The connecting rod 7 is arranged at the top opening of the material box 2 to connect the two symmetrical second side plates 4. The stop block 8 is arranged on the connecting rod 7 and used to block the downward sliding of the pipe materials. The supporting plate 9 is arranged beside the blanking port 6. The initial position of the supporting plate 9 is lower than that of the bottom plate 5. The supporting plate 9 has a slope 10. The supporting plate 9 is used to lift the pipe materials sliding out of the material box 2. Because of the slope 10, the pipe materials will roll down from the slope 10. The first cylinder 11 is arranged under the supporting plate 9 and used to lift the supporting plate 9. The detection switch 12 is used to detect whether there are pipe materials on the supporting plate 9 and control the operation of the first cylinder 11. The V-shaped block 13 is arranged beside the supporting plate 9 and used to receive the pipe materials sliding out of the supporting plate 9. The V-shaped block 13 is V-shaped and can center the pipe materials therein. The second cylinder 14 is coaxially arranged with the V-shaped block 13 and used to push the pipe materials in the V-shaped block 13.

[0033] During use, when the pipe materials need to be loaded, the pipe materials are loaded into the material box 2. The bottom-layer pipe materials can slide out downward, and the other-layer pipe materials are kept in the material box 2 by the connecting rod 7 and the stop block 8. When a pipe material descends to the supporting plate 9, the detection switch 12 detects that there is a pipe material on the supporting plate 9, controls the first cylinder 11 to start, lifts the supporting plate 9, enables the pipe material to slide out of the supporting plate 9 along the slope 10 and enter the V-shaped block 13, and the second cylinder 14 starts to push the pipe materials in the V-shaped block 13 into the machine to be processed, such as a stamping machine or a pipe cutting machine, etc., to realize the intermittent feeding of the pipe materials.

[0034] It should be noted that the limiting plate 15 is arranged in parallel with the second side plate 4 and is located inside the material box 2. The size of the limiting plate 15 is adapted to the internal size of the material box 2 to ensure that the limiting plate 15 can be stably located inside the material box 2. One end of the adjusting rod 16 is connected to the limiting plate 15, and the other end is threadedly connected to the second side plate 4. The adjusting rod 16 is made of a stainless steel rod, aluminum material, plastic or other hard materials with a diameter, and has sufficient strength and stability. The threaded part of the adjusting rod 16 cooperates with the threaded hole on the second side plate 4. By rotating the adjusting rod 16, the distance between the limiting plate 15 and the second side plate 4 can be adjusted. The function of the limiting plate 15 is to sort the pipe materials of different lengths and improve the applicability of the material box 2. For example, if the width of the material box 2 is 100 cm, it can be applicable to all pipe materials within 100 cm in length. When the pipe material is 60 cm, the limiting plate 15 is adjusted to a suitable position through the adjusting rod 16, and a suitable cavity can be formed inside the material box 2.

[0035] Further, the U-shaped groove 17 is provided on the stopper 8 as shown in the figure. The U-shaped groove 17 is U-shaped, and its opening width is slightly larger than the outer diameter of the pipe material so that the pipe material can smoothly enter the groove. The depth of the U-shaped groove 17 is designed according to the outer diameter of the pipe material to ensure that the pipe material is stably positioned in the groove and does not slide out downward.

[0036] It should be noted that multiple stoppers 8 are provided. Some pipe materials are heavier. Especially when a lot of pipe materials are stacked, the downward gravity causes a large downward kinetic energy, and multiple stoppers 8 need to be provided.

[0037] Further, the limit block 18 is provided on the side of the V-shaped block 13 away from the material frame 2. The main function of the limit block 18 is to prevent the pipe material from having too high a speed, rushing out of the V-shaped block 13, and rolling onto the workbench 1.

[0038] It should be noted that the slope 10 is located at the top of the pallet 9, and the angle between it and the horizontal plane is between 20 - 35 degrees. The design of this slope 10 enables the pipe material to smoothly slide into or out of the pallet 9. When the pipe material rolls onto the slope 10, due to the angle between the slope 10 and the horizontal plane, the pipe material will naturally slide under the action of gravity to the lower part of the pallet 9.

[0039] It should be noted that the top block 19 is provided at the end of the telescopic rod of the second cylinder 14 for pushing the pipe material. The top block 19 is made of wear-resistant material, has high hardness and strength, and can withstand a large pushing force. The top block 19 is firmly connected to the telescopic rod of the second cylinder 14 to ensure that it will not fall off during the pushing process.

[0040] It should be pointed out that the anti-slip layer 20 is sleeved on the surface of the top block 19. The anti-slip layer 20 is made of rubber, silica gel or other materials with a high friction coefficient, which can effectively increase the friction between the top block 19 and the contact surface and prevent sliding. According to actual application requirements, the thickness of the anti-slip layer 20 can be adjusted between 2 mm and 10 mm to adapt to different scenarios.

[0041] It should be pointed out that the length of the second side plate 4 is greater than the length of the bottom plate 5, which makes the pallet 9 located between the two second side plates 4. After the pipe material slides out of the bottom plate 5, it is still within the enclosure of the two second side plates 4 and the pallet 9, and the pipe material will not slip off, and the stability of the entire structure has been significantly improved.

[0042] Further, the angle between the material frame 2 and the horizontal direction is set to be not less than 20 degrees. This angle is achieved by adjusting the inclination angle of the bottom plate 5 part of the material frame 2. The bottom plate 5 is made of a metal or plastic plate with a certain thickness, and its inclination angle can be adjusted by a support rod fixed on the workbench 1. When the angle between the material frame 2 and the horizontal direction is 30 degrees, the stability of the material frame 2 is better, the downward force of the pipe material during transportation is relatively stable, the pipe material is easy to slide off, but the upper pipe material is not easy to roll out.

[0043] Although embodiments of the present application have been shown and described, those of ordinary skill in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
