DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figure 1-Figure 22 As shown, the technical solution adopted by the present invention is as follows: a feeding device for cutting metal pipes includes a base 1 and a supporting mechanism.

[0046] There are two supporting mechanisms, both of which are slidably arranged on the base 1.

[0047] Each support mechanism includes a fixed ring 5 and two scroll plates. The fixed ring 5 is slidably mounted on the base 1. Specifically, the fixed ring 5 is fixedly connected to two support blocks 4, both of which are slidably mounted on the base 1. The base 1 is equipped with an electrically controlled slide rail 3 that drives the support blocks 4 to slide.

[0048] The fixing ring 5 is rotatably connected to the annular plate 7, and the annular plate 7 is rotatably connected to the circular plate 13. The fixing ring 5, the annular plate 7 and the circular plate 13 are coaxially arranged.

[0049] like Figure 4As shown, the fixing ring 5 has a mounting cavity, within which a first motor 9 is mounted. The output shaft of the first motor 9 is fixedly connected to a gear 10. The annular plate 7 is fixedly connected to a gear ring 8, which meshes with the gear 10. Both the gear ring 8 and the gear 10 are located within the mounting cavity. The first motor 9 drives the annular plate 7 to rotate via the gear 10 and the gear ring 8.

[0050] The annular plate 7 is fixedly connected to a fixing frame 11, and a second motor 12 is fixedly mounted on the fixing frame 11. The output shaft of the second motor 12 is fixedly connected to the circular plate 13. The second motor 12 drives the circular plate 13 to rotate relative to the annular plate 7.

[0051] One of the vortex plates is fixedly mounted on the annular plate 7, and the other vortex plate is fixedly mounted on the circular plate 13. In this embodiment, the spiral directions of the two vortex plates are the same.

[0052] The two vortex plates form a material receiving channel. The pipe 27 is placed in the material receiving channel between the two vortex plates.

[0053] The circular plate 13 is rotated relative to the annular plate 7, thereby rotating the vortex plate connected to the circular plate 13, so that the width of the material holding channel between the two vortex plates becomes larger or smaller, thereby adapting to pipes 27 with different outer diameters.

[0054] Each scroll plate is provided with a transmission assembly. The transmission assembly includes a transmission belt 20 and a driving member. The transmission belt 20 is slidably sleeved on the scroll plate. Figure 15 、 Figure 16 As shown, grooves 16 are provided on both sides of the scroll plate, and the transmission belt 20 is arranged in the grooves 16. The driving member is installed on the scroll plate to drive the transmission belt 20 to slide along the scroll plate.

[0055] The drive element includes a transmission roller 17. A transmission roller 17 is rotatably mounted at each end of the scroll plate. A transmission belt 20 is wound between the two transmission rollers 17. A third motor 19 is fixedly connected to each end of the scroll plate. The output shaft of the third motor 19 is fixedly connected to the corresponding transmission roller 17.

[0056] The third motor 19 drives the transmission roller 17 to rotate, thereby causing the transmission belt 20 to slide along the scroll plate.

[0057] To ensure smooth sliding of the drive belt 20 along the scroll plate, two sprockets 18 are fixedly connected to each drive roller 17. Two chains 21 are fixedly mounted on the inner side of the drive belt 20, with each chain 21 corresponding to each sprocket 18. The chains 21 mesh with the corresponding sprockets 18. The drive rollers 17 rotate the sprockets 18, which in turn drive the chains 21, allowing the drive belt 20 to slide smoothly along the scroll plate.

[0058] like Figure 18As shown, the chain 21 is embedded in the drive belt 20 so that the drive belt 20 remains in contact with the scroll plate.

[0059] A rubber layer 22 is fixedly connected to the outside of the transmission belt 20. The rubber layer 22 protrudes from the scroll plate. When the pipe 27 enters between the two scroll plates, the pipe 27 contacts the rubber layer 22, preventing the pipe 27 from being damaged by the rigid clamping of the scroll plates.

[0060] An L-shaped guide plate 6 is fixedly connected to one side of the fixing ring 5. A supporting guide plate 2 is installed in the middle of the base 1.

[0061] Multiple pipes 27 are sequentially placed between the two L-shaped guide plates 6. Guided by the L-shaped guide plates 6, the ends of the pipes 27 enter between the scroll plates on the two support mechanisms. The third motor 19 is activated, causing the drive belt 20 to slide along the scroll plates. The drive belt 20 drives the pipes 27 along the material receiving channel between the two scroll plates and into the scroll plates, thereby sequentially moving the pipes 27 into the scroll plates. The pipes 27 are fixedly mounted between the two support mechanisms, and the cutting mechanism can then be used to cut the pipes 27 between the two support mechanisms.

[0062] After the cutting is completed, the third motor 19 rotates in the opposite direction, so that the transmission belt 20 slides along the vortex plate. The transmission belt 20 drives the pipe fittings 27 to move outside the vortex plate along the material receiving channel between the two vortex plates, thereby making the multiple pipe fittings 27 after cutting move to the outside of the vortex plate in turn, completing the automatic blanking.

[0063] A retaining plate 23 is fixedly connected to the scroll plate, which is fixedly connected to the annular plate 7. A sliding groove is defined in retaining plate 23, within which a retaining plate 25 slides. A spring 24 is disposed within the sliding groove and fixedly connected between retaining plate 25 and retaining plate 23. A roller 26 is rotatably connected to the end of retaining plate 25 that is away from retaining plate 23.

[0064] Working Principle: For ease of description, the scroll plate connected to the annular plate 7 is named the first scroll plate 14, and the scroll plate connected to the circular plate 13 is named the second scroll plate 15. In this embodiment, the material receiving channel is located between the side of the second scroll plate 15 closest to the axis of the stationary ring 5 and the side of the first scroll plate 14 farther from the axis of the stationary ring 5. The opening of the material receiving channel is located at the end of the first scroll plate 14 farther from the axis of the stationary ring 5.

[0065] First, the outer diameter of the tube 27 is cut as needed to adjust the width of the material channel. This ensures that the channel matches the outer diameter of the tube 27. The spacing between the two rubber layers 22 in the channel is smaller than the outer diameter of the tube 27. This ensures that the tube 27 entering the channel contacts the rubber layers 22, allowing the transmission belt 20 to drive the tube 27 along the channel through the rubber layers 22.

[0066] Specifically, the second motor 12 is started, the second motor 12 drives the circular plate 13 to rotate, and the circular plate 13 drives the second scroll plate 15 to rotate, as shown in FIG. Figure 21 In the direction shown, the second scroll plate 15 rotates counterclockwise relative to the first scroll plate 14, thereby reducing the width of the material receiving channel. The second scroll plate 15 rotates clockwise relative to the first scroll plate 14, thereby increasing the width of the material receiving channel.

[0067] Start the first motor 9, which drives the annular plate 7 to rotate through the gear 10 and the gear ring 8, and the circular plate 13, the first scroll plate 14 and the second scroll plate 15 rotate accordingly, so that the opening of the material channel faces upward and cooperates with the L-shaped guide plate 6, as shown in FIG. Figure 21 shown.

[0068] Then, the electric-controlled slide rail 3 is started to slide the support block 4 on the base 1 , thereby adjusting the distance between the two support mechanisms so that the distance between the vertical portions of the two L-shaped guide plates 6 matches the length of the pipe 27 .

[0069] Then multiple pipe fittings 27 are sequentially placed between the two L-shaped guide plates 6. The pipe fittings 27 slide downward along the L-shaped guide plates 6, and the ends of the pipe fittings 27 enter the material holding channel, and the ends of the multiple pipe fittings 27 enter the material holding channel in sequence.

[0070] Start the third motor 19, the third motor 19 drives the transmission roller 17 to rotate, the sprocket 18 to rotate, the sprocket 18 drives the chain 21 to rotate, and then the transmission belt 20 slides along the vortex plate, and the transmission belt 20 drives the pipe 27 to gradually slide into the material holding channel, that is, gradually approach the axis of the fixed ring 5.

[0071] Until the pipe 27 that first enters the material holding channel abuts against the baffle 25 and the material holding channel is filled, multiple pipes 27 are arranged in sequence in the material holding channel, and the multiple pipes 27 are all fixed on the supporting mechanism.

[0072] Then, the second motor 12 is started, as shown in FIG. Figure 21 In the direction shown, the circular plate 13 rotates counterclockwise, and the second scroll plate 15 rotates counterclockwise relative to the first scroll plate 14. The width of the material holding channel is further reduced, and the pipe 27 squeezes the rubber layer 22, causing the rubber layer 22 to further deform, and then the pipe 27 is further clamped and fixed in the material holding channel, which is convenient for subsequent cutting.

[0073] Afterwards, the multiple pipe fittings 27 installed on the two supporting mechanisms can be cut by the cutting mechanism. Multiple pipe fittings 27 can be cut simultaneously at one time, which is beneficial to improving the cutting efficiency.

[0074] After the cutting is completed, the two cut pipes 27 are respectively placed on the two supporting mechanisms. Then, the first motor 9 is started, the annular plate 7 rotates, and the annular plate 7 drives the circular plate 13, the first vortex plate 14 and the second vortex plate 15 to rotate synchronously, so that the opening of the material receiving channel faces downward, as shown in FIG. Figure 22 Then place the receiving trolley under the opening.

[0075] Thereafter, the third motor 19 is started to slide the transmission belt 20 along the scroll plate. The transmission belt 20 drives the pipe 27 to slide toward the opening of the material receiving channel through the rubber layer 22, and falls into the material receiving trolley from the opening.

[0076] The feeding device of the present invention can fix the pipe 27 while discharging the pipe 27, thereby completing the loading process, facilitating the subsequent cutting process, and improving the processing efficiency of the pipe 27. After the cutting is completed, the movement of the transmission belt 20 causes the pipes 27 to be discharged from the material receiving channel in sequence, completing the automatic unloading process.

[0077] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
