[0036] Embodiment 1

[0037] As Figures 1-5 shown, a round tube blank feeding device includes a rear-end feeding device 1, a conveying device 2 and a front-end stop device 6, and the conveying device 2 is located between the rear-end feeding device 1 and the front-end stop device 6;

[0038] A conveying plate 24 is provided between the conveying device 2 and the rear feeding device 1 and the front material blocking device 6 respectively. The conveying plate 24 at the rear end is adapted to guide the material onto the conveying device 2, and the conveying plate 24 at the front end is adapted to guide the material onto the front material blocking device 6. A through groove is provided in the middle of the conveying plate 24;

[0039] Feeding devices 3 are provided at the intervals between the conveying device 2 and the rear feeding device 1 and the front material blocking device 6 respectively. The feeding device 3 includes a rotatable feeding plate 32, and the feeding plate 32 is adapted to rotate to push the material forward to generate a displacement after passing through the through groove on the conveying plate 24.

[0040] As Figure 1 , Figure 5 shown, the rear feeding device 1 includes a rear feeding support 11, and the front material blocking device 6 includes a fixed support 61. One end of the feeding plate 32 located between the conveying device 2 and the rear feeding device 1 is rotatably installed on the rear feeding support 11, and one end of the feeding plate 32 located between the conveying device 2 and the front material blocking device 6 is rotatably installed on the fixed support 61;

[0041] The feeding device 3 further includes a telescopic cylinder 31. The telescopic cylinder 31 is located at the bottom of the feeding plate 32, and the top of the telescopic end of the telescopic cylinder 31 is movably hinged to the other end of the feeding plate 32.

[0042] As Figures 1-4 shown, the rear feeding device 1 includes a rear material blocking component 16. The rear material blocking component 16 includes a rear material blocking plate 14, and the rear material blocking plate 14 is adapted to move in a rotating manner in the through groove between the conveying plates 24 to control the movement of the material.

[0043] As Figure 1 , Figure 4 shown, the rear material blocking component 16 further includes a support, a material blocking cylinder 12 and a material blocking shaft 13. The housing of the material blocking cylinder 12 is movably hinged to the support, the material blocking shaft 13 is rotatably installed on the support, an articulated block 15 is fixedly sleeved on the outside of the material blocking shaft 13, and the inside of the articulated block 15 is movably hinged to the telescopic end of the material blocking cylinder 12. The rear material blocking plate 14 is fixedly sleeved on the outer peripheral surface of the material blocking shaft 13.

[0044] As Figure 2 , Figure 4 shown, the conveying device 2 includes a platform and at least two groups of conveying rollers 23 adapted to be driven by a driving motor 21 to rotate. The conveying rollers 23 are rotatably installed on the platform. One of the conveying rollers 23 is connected to the driving motor 21 through a driving shaft 22. A conveying wheel is coaxially connected to the conveying roller 23, and a conveyor belt 25 is connected to the conveying wheel.

[0045] As Figures 4-5As shown in the figure, the front-end material blocking device 6 includes a fixed bracket 61. Inside the fixed bracket 61, a rotating shaft 62 suitable for being driven to rotate by a motor is rotatably installed. A material blocking plate member 63 is fixedly sleeved on the outer peripheral surface of the rotating shaft 62. The material blocking plate member 63 is suitable for passing through the through groove on the conveying plate 24 to limit the material.

[0046] The working principle of this embodiment is as follows:

[0047] Place the round tube blank to be loaded on the rear-end loading bracket 11. At this time, the round tube blank is restricted by the rear-end material blocking plate 14 and will not enter the conveying device 2. When it is necessary to start conveying, start the material blocking cylinder 12 to drive its telescopic end to contract, causing the hinge block 15 to rotate. When the hinge block 15 rotates, it will drive the rear-end material blocking plate 14 to rotate to a position lower than the plane where the round tube blank is placed. At this time, the round tube blank loses its restriction and will enter the conveying device 2 through its own rolling along the conveying plate 24 and start to be transported;

[0048] Since the roundness of the diameter of the round tube blank is not high and it is not a standard circle, but there are various surface defects such as depressions, it will cause the phenomenon of being unable to roll and getting stuck during the process of rolling by its own gravity and cannot normally enter the conveying device 2. Therefore, a material pushing device 3 is provided. The material pushing device 3 realizes the swinging of the material pushing plate 32 under the reciprocating telescoping of the telescopic cylinder 31 to vibrate the round tube blank and promote the round tube blank to continue rolling to avoid getting stuck;

[0049] After being vibrated, the round tube blank can stably enter the conveying device 2 and start to be transported. The conveying device 2 is controlled by the driving motor 21. The driving motor 21 drives the conveying shaft and the conveying roller 23 to rotate, thereby realizing the belt transmission of the round tube blank;

[0050] When the round tube blank is conveyed to the limit stroke of the conveying device 2, it will continue to roll along the direction of the conveying plate 24 to the front-end material blocking device 6. A material pushing device 3 is also provided between the conveying device 2 and the front-end material blocking device 6 to avoid the phenomenon of getting stuck during the movement of the round tube blank;

[0051] When the round tube blank moves onto the front-end material blocking device 6, it will be restricted by the material blocking plate member 63 and stop moving, waiting for the next process to move the conveyed round tube blank to another conveying line. The material blocking plate member 63 can be driven to rotate by a driving device such as a motor. The rotatable setting can control the limit position of the movement of the round tube blank and can be adjusted for round tube blanks of different diameters to ensure that the next process can stably take out all the round tube blanks.

[0052] Embodiment Two

[0053] As Figure 3 、 Figure 5As shown in the figure, this embodiment further includes the following structure on the basis of Embodiment 1: It further includes a feeding component 4. The feeding component 4 is located on one side of the front end material blocking device 6. The feeding component 4 includes a rotatable feeding plate 43. The feeding plate 43 is adapted to take out the material in a rotational manner through the through groove on the conveying plate 24.

[0054] The feeding plate 43 includes a hook-shaped portion 44 and a guiding surface 45. The hook-shaped portion 44 is adapted to hook out the material and then convey it by rolling along the guiding surface 45.

[0055] As Figure 3 , Figure 5 shown in the figure, the feeding component 4 further includes a rear end feeding seat 46, a swing shaft adapted to be driven to rotate, a feeding cylinder 41, and a hinged rod 42. The outer shell of the feeding cylinder 41 is hinged inside the rear end feeding seat 46. One end of the feeding plate 43 is fixedly connected to the swing shaft. One end of the hinged rod 42 is fixedly connected to the swing shaft, and the other end of the hinged rod 42 is hinged to the telescopic end of the feeding cylinder 41.

[0056] As Figure 6 shown in the figure, a turning and transporting device 5 is arranged at the top of the feeding component 4. The turning and transporting device 5 includes a transporting shaft 52 adapted to be driven by a second driving motor 51 to rotate and transporting rollers 53. The transporting shaft 52 is rotatably installed inside the turning and transporting device 5. The transporting rollers 53 are fixedly sleeved on the outer peripheral surface of the transporting shaft 52. The feeding plate 43 is adapted to move the material along the direction of the guiding surface 45 onto the transporting rollers 53. The transporting rollers 53 are adapted to turn and then convey the material;

[0057] A groove is arranged in the middle of the transporting roller 53, and the groove is suitable for placing the material.

[0058] The working principle of this embodiment is as follows:

[0059] When the round tube blanks stay at the designated position on the front end material blocking device 6 and all the round tube blanks need to be taken out one by one and moved to another conveying line, the feeding cylinder 41 is started. When the telescopic end of the feeding cylinder 41 contracts, it drives the angle of the hinged rod 42 to shift, thereby driving the feeding plate 43 to rotate at the same angle. During the rotation, the round tube blanks are taken out one by one;

[0060] During the process of taking out the round tube blanks, the hook-shaped portion 44 of the feeding plate 43 will block between two adjacent round tube blanks. The round tube blank located in front of the hook-shaped portion 44 will be driven to move together. During the movement, the round tube blank will naturally roll onto the transporting rollers 53 along the direction of the guiding surface 45. At this time, the round tube blank changes from the initial horizontal transportation to vertical movement and moves through the cooperation of multiple transporting rollers 53. The turning setting can make the entire feeding and transporting process more flexible and facilitate adapting to various actual application scenarios;

[0061] The rotation of the transport roller 53 is driven by the second drive motor 51. At the same time, the part of the transport roller 53 for placing the round tube blank is a groove, and the whole groove is V-shaped. This setting can adapt to round tube blanks of various different diameters and ensure the stability during transportation.

[0062] In the specific embodiments described above, the technical problems solved, technical solutions and beneficial effects of the present utility model are further described in detail. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
