[0037] like Figure 1-Figure 6 As shown, according to the first aspect of the embodiment of the present application, there is provided a material shaft 100, comprising a shell 1, a driving mechanism 3 and a tensioning mechanism 2; a guide hole 11 is opened on the shell 1, and the guide hole 11 is located between the two axial ends of the shell 1, and the axis of the guide hole 11 intersects with the axis of the shell 1; the driving mechanism 3 is at least partially arranged inside the shell 1; the tensioning mechanism 2 comprises a connecting rod 21 and a push block 22, one end of the connecting rod 21 is hinged to the driving mechanism 3 along the radial direction of the shell 1, and the push block 22 is hinged to the other end of the connecting rod 21 along the radial direction of the shell 1, and the push block 22 is at least partially located in the guide hole 11, and the driving end of the driving mechanism 3 can move along the axial direction of the shell 1 to drive the connecting rod 21 to rotate around the radial direction of the shell 1, and the push block 22 can move along the axial direction of the guide hole 11 to be exposed from the guide hole 11 or be located inside the shell 1.

[0038] The embodiment of the present application provides a material shaft 100, which can be used in an AGV vehicle 200 to load materials.

[0039] like Figure 1-Figure 3 As shown, the material shaft 100 includes a housing 1 , a driving mechanism 3 and a tensioning mechanism 2 .

[0040] The housing 1 is in the shape of a hollow column, and may be a hollow cylinder, a hollow prism or a hollow cuboid. In the embodiment of the present application, the housing 1 is in the shape of a hollow cylinder as an example for description.

[0041] To further explain, the housing 1 has a containing space inside, and a guide hole 11 is opened on the housing 1 . The guide hole 11 is connected to the containing space, and the axis of the guide hole 11 intersects with the axis of the housing 1 .

[0042] Further explanation: the driving mechanism 3 is at least partially disposed inside the housing 1, that is, disposed in the accommodation space; if the driving mechanism 3 is partially disposed inside the housing 1, then the driving end of the driving mechanism 3 is disposed inside the housing 1; the driving mechanism 3 may also be entirely disposed inside the housing 1. The driving end of the driving mechanism 3 can move along the axial direction of the housing 1.

[0043] Further explanation, such as Figure 4 and Figure 5 As shown, the tensioning mechanism 2 includes a connecting rod 21 and a push block 22; wherein, one end of the connecting rod 21 is hinged to the driving end of the driving mechanism 3, and one end of the connecting rod 21 can rotate relative to the driving end of the driving mechanism 3 along the radial direction of the housing 1; the other end of the connecting rod 21 is hinged to the push block 22, and the connecting rod 21 can be connected to the push block 22 along the radial direction of the housing 1; the push block 22 can move axially along the guide hole 11, and the push block 22 is at least partially located in the guide hole 11; when the driving end of the driving mechanism 3 moves toward the driving mechanism 3, one end of the connecting rod 21 moves along the axial direction of the housing 1 toward the driving mechanism 3, and the axial distance between the two ends of the connecting rod 21 in the housing 1 gradually increases, and then the radial distance between the two ends of the connecting rod 21 in the housing 1 will gradually decrease, so the push block 22 will be driven to move toward the center of the housing 1, In this way, the size of the push block 22 exposed inside the shell 1 is reduced, and it may not even be exposed in the guide hole 11. At this time, the material roll 300 can be passed through the material shaft 100. After the material is passed through the material shaft 100, the driving end of the driving mechanism 3 moves along the axial direction of the shell 1 in the direction away from the driving mechanism 3, and one end of the connecting rod 21 moves along the axial direction of the shell 1 in the direction away from the driving mechanism 3. The distance between the two ends of the connecting rod 21 in the axial direction of the shell 1 gradually decreases, and then the distance between the two ends of the connecting rod 21 in the radial direction of the shell 1 will gradually increase, so the push block 22 will be driven to move in the direction away from the center of the shell 1, so that the push block 22 will be partially exposed in the guide hole 11. When the push block 22 is exposed in the guide hole 11, the push block 22 will hold the material roll 300 on the material shaft 100 tightly, thereby preventing the material roll 300 from falling off the material shaft 100.

[0044] The material shaft 100 provided in the embodiment of the present application, when there are multiple material rolls 300 arranged closely on the cache rack, the material shaft 100 passes through the material roll 300 shaft, and the push block 22 is located between the two ends of the shell 1, so it is only necessary to drive the push block 22 to move along the radial direction of the shell 1, so that the push block 22 can hold the material roll 300 tightly, so as to take one or more material rolls 300 on the cache rack, which has high compatibility and can improve work efficiency. .

[0045] In an optional embodiment, the material shaft 100 also includes a first mounting plate 6 and a guide rod 4, and the guide rod 4 is arranged on the first mounting plate 6 along the axial direction of the outer shell 1; the driving mechanism 3 includes a connecting plate 34, and the connecting plate 34 is provided with a through hole 341, and the guide rod 4 is passed through the through hole 341, and the connecting plate 34 can move along the axial direction of the outer shell 1 and slide relative to the guide rod 4, and the connecting rod 21 is hinged to the connecting plate 34 along the radial direction of the outer shell 1.

[0046] like Figure 1 As shown, the material shaft 100 further includes a first mounting plate 6 and a guide rod 4 , one end of the guide rod 4 is connected to the first mounting plate 6 , and the length direction of the guide rod 4 is the same as the axial direction of the housing 1 .

[0047] Further description, the driving mechanism 3 includes a connecting plate 34, which is located at the driving end of the driving mechanism 3. A through hole 341 is opened on the connecting plate 34, and the axis of the through hole 341 is in the same direction as the axis of the outer shell 1; the connecting plate 34 and the first mounting plate 6 are arranged at an axial distance along the outer shell 1, and the guide rod 4 can be inserted into the through hole 341, and the connecting plate 34 can move along the length direction of the guide rod 4.

[0048] Further, the connecting rod 21 is hinged with the connecting plate 34, so that the connecting rod 21 can rotate relative to the connecting plate 34 around the radial direction of the housing 1. When the driving end of the driving mechanism 3 moves along the axial direction of the housing 1, that is, the connecting plate 34 can slide along the length direction of the guide rod 4, the guide rod 4 can provide a guiding effect for the connecting plate 34, and the guide rod 4 can also provide a supporting effect for the connecting plate 34 to prevent the connecting plate 34 from deflecting.

[0049] In an optional embodiment, a protrusion 61 is formed at one end of the first mounting plate 6 close to the guide rod 4, and the outer diameter of the protrusion 61 is smaller than the outer diameter of the first mounting plate 6; an annular protrusion is formed on the inner wall of one end of the outer shell 1, and the annular protrusion has an annular hole, and the protrusion 61 is embedded in the annular hole, the side wall of the first mounting plate 6 abuts against the inner wall of the outer shell 1, and the first mounting plate 6 is connected to the annular protrusion through a connecting piece.

[0050] Further explanation: a protrusion 61 is formed at one end of the first mounting plate 6, and the protrusion 61 and the first mounting plate 6 can be an integral structure, or the protrusion 61 can be installed on the end surface of the first mounting plate 6; the outer diameter of the first mounting plate 6 is larger than the outer diameter of the protrusion 61, and the guide rod 4 is connected to the protrusion 61; an annular protrusion is formed on the inner wall of the shell 1, and the annular protrusion has an annular hole, and the annular protrusion is at a certain distance from the end of the shell 1, and the protrusion 61 is embedded in the annular hole of the annular protrusion, so the first mounting plate 6 can be located inside the shell 1, and the side wall of the first mounting plate 6 abuts against the inner wall of the shell 1, and the first mounting plate 6 abuts against the annular protrusion, and the first mounting plate 6 and the annular protrusion are connected by a connecting piece.

Thus, both ends of the guide rod 4 have support points, and when the connecting plate 34 slides along the guide rod 4, the guide rod 4 can avoid the guide rod 4 tilting downward under the action of the gravity of the connecting plate 34 and the material roll, which causes the connecting plate 34 to slide unsmoothly.

[0054] In an optional embodiment, a plurality of adjusting screws 8 are provided on the circumference of the second mounting plate 7, and the plurality of adjusting screws 8 are distributed at intervals along the circumference of the second mounting plate 7; the adjusting screws 8 abut against the inner wall of the outer shell 1, and the adjusting screws 8 can adjust the gap between the second mounting plate 7 and the outer shell 1 along the radial direction of the outer shell 1.

[0056] Further, the adjusting screw 8 abuts against the inner wall of the housing 1, and the gap between the second mounting plate 7 and the housing 1 can be adjusted by adjusting the screw 8, so that the second mounting plate 7 and the housing 1 can be locked by adjusting the screw 8 to improve the structural strength of the material shaft 100. And the center of the housing 1 can be adjusted to be consistent with the center of the connecting plate 34 by adjusting the screw 8 to prevent the push block 22 from being deflected in the guide hole 11.

Therefore, by providing a plurality of tensioning mechanisms 2, when the material roll 300 is sleeved on the material shaft 100, the material roll 300 is subjected to a more uniform force, which can prevent the material roll 300 from being offset or falling on the material shaft 100 when the material shaft 100 moves.

[0060] To further illustrate, multiple tensioning mechanisms 2 are connected to the connecting plate 34. When the connecting plate 34 moves along the axial direction of the shell 1, the push blocks 22 of the multiple tensioning mechanisms 2 can move simultaneously to achieve the tightening or loosening of the material roll 300.
