Detailed Implementation

[0041] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0042] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0043] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0044] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0045] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0046] First, it should be noted that the X, Y, and Z directions mentioned in the embodiments of this application are referred to in the appendix. Figure 4 , Figure 8 The marked directions. Among them, the axes in the X direction, Y direction, and Z direction intersect each other.

[0047] like Figures 1-10 According to a first aspect of the embodiments of this application, an unwinding mechanism 100 is provided, including a first driving component 2, a transmission component 4, a tensioning shaft 5, and a first mounting base 6; the transmission component 4 is disposed at the output end of the first driving component 2, and the transmission component 4 has a groove 41; the end of the tensioning shaft 5 is placed in the groove 41; the first mounting base 6 and the transmission component 4 are spaced apart along the X direction, and the tensioning shaft 5 is rotatably connected to the first mounting base 6.

[0048] like Figures 1-10 As shown, the unwinding mechanism 100 includes a first drive assembly 2, a transmission assembly 4, a tensioning shaft 5, and a first mounting base 6; wherein, the tensioning shaft 5 is used to mount the material roll, and when the tensioning shaft 5 rotates around its own axis, it can unwind or rewind, and the first drive assembly 2 can provide power for the rotation of the tensioning shaft 5 around itself.

[0049] In related technologies, gear transmission is used between the transmission component 4 and the tensioning shaft 5. When the material roll is unwound or rewound, it is inconvenient to disassemble the tensioning shaft 5 and the transmission component 4, which will affect the working efficiency of the unwinding mechanism 100.

[0050] like Figure 1 , Figure 6 and Figure 10 As shown, the transmission assembly 4 is connected to the output end of the first drive assembly 2. The transmission assembly 4 has a groove 41, the length direction of which is the same as the X direction. The tensioning shaft 5 is placed in the groove 41, and the direction of the axis of the tensioning shaft 5 is the same as the length direction of the groove 41. The first mounting seat 6 is spaced apart from the transmission assembly 4 in the X direction. The first mounting seat 6 is located on the side of the transmission assembly 4 away from the first drive assembly 2. The tensioning shaft 5 is rotatably connected to the first mounting seat 6. The tensioning shaft 5 can rotate relative to the first mounting seat 6 around its own axis. The first mounting seat 6 can provide support for the tensioning shaft 5 in the Z direction.

[0051] Specifically, the axial direction of the transmission component 4 is the same as the length direction of the groove 41; when the first drive component 2 drives the transmission component 4 to rotate around its own axis, the end of the tensioning shaft 5 is located in the groove 41, so that the transmission component 4 can drive the tensioning shaft 5 to rotate around its own axis.

[0052] In the unwinding mechanism 100 of this application, the end of the tensioning shaft 5 is directly placed in the groove 41, which greatly improves the convenience of installation and disassembly of the tensioning shaft 5 and the transmission assembly 4, thereby improving the loading and unloading efficiency of the unwinding mechanism 100; and the first mounting seat 6 can provide support for the tensioning shaft 5, avoiding the problem of unstable rotation of the tensioning shaft 5.

[0053] In one alternative embodiment, the radial cross-section of the groove 41 is V-shaped; the tensioning shaft 5 includes a connecting shaft section 51, the radial cross-section of which is V-shaped, and the connecting shaft section 51 is placed within the groove 41. When the transmission assembly 4 rotates about its own axis, relative sliding between the groove 41 and the connecting shaft section 51 can be avoided, thereby improving the transmission stability between the transmission assembly 4 and the tensioning shaft 5.

[0054] Among them, the connecting shaft section 51 of the tensioning shaft 5 is connected to the first end 52, the connecting shaft section 51 is placed in the groove 41, and the first end 52 is rotatably connected to the first mounting base 6.

[0055] In one optional embodiment, the first drive assembly 2 includes a first drive member 21 and a ball spline 22. The first drive member 21 includes an output shaft 211. The ball spline 22 is connected to the output shaft 211. The ball spline 22 is movable relative to the output shaft 211 in the X direction. The transmission assembly 4 is disposed on the ball spline 22.

[0056] In related technologies, during the unwinding and winding process, the tension shaft 5 may deviate due to vibration, shaking and other problems. Therefore, it is necessary to correct the deviation of the tension shaft 5 to improve the efficiency and quality of unwinding and winding.

[0057] like Figure 2 , Figure 6 and Figure 10As shown, the first drive assembly 2 includes a first drive member 21 and a ball spline 22; wherein, the first drive member 21 includes an output shaft 211, which is connected to the ball spline 22, and the ball spline 22 can move relative to the output shaft 211 in the X direction; the transmission assembly 4 is connected to the ball spline 22, and one end of the tensioning shaft 5 is placed in the groove 41 of the transmission assembly 4; the first drive member 21 can drive the ball spline 22 to rotate around the axis in the X direction through the output shaft 211, and can drive the tensioning shaft 5 to rotate around its own axis through the transmission assembly 4, and the ball spline 22 can also move relative to the output shaft 211 in the X direction, so that the tensioning shaft 5 can be driven to move in the X direction through the transmission assembly 4 to achieve the correction function.

[0058] The transmission component 4 is mounted on the ball spline 22 by utilizing the linear movement between the ball spline 22 and the output shaft 211. By moving the ball spline 22 relative to the output shaft 211 in the X direction, the deviation correction is achieved, which reduces the resistance of the tensioning shaft 5 when moving in the X direction, thereby improving the stability and deviation correction efficiency of the unwinding mechanism 100. Furthermore, the ball spline 22 has the characteristics of high transmission efficiency, high precision, low wear, ability to withstand multi-directional loads, and easy maintenance, thereby improving the working efficiency and control accuracy of the unwinding mechanism 100.

[0059] In an optional embodiment, the unwinding mechanism 100 further includes a second mounting base 7, a mounting plate 11, a first support base 9, and a first sliding assembly 12. The second mounting base 7 and the first mounting base 6 are spaced apart on the mounting plate 11 along the X direction. The ball spline 22 is rotatably connected to the second mounting base 7. The first support base 9 is located below the mounting plate 11. The mounting plate 11 and the first support base 9 are slidably connected through the first sliding assembly 12.

[0060] like Figure 2 and Figure 6 As shown, the unwinding mechanism 100 also includes a second mounting base 7, a mounting plate 11, a first support base 9, and a first sliding assembly 12; wherein, the second mounting base 7 and the first mounting base 6 are spaced apart along the X direction, the transmission assembly 4 is located between the first mounting base 6 and the second mounting base 7, and both the first mounting base 6 and the second mounting base 7 are mounted on the mounting plate 11; the ball spline 22 is rotatably connected to the second mounting base 7. Specifically, the second mounting base 7 has a through hole, and a bearing is sleeved inside the through hole. The outer wall of the ball spline 22 is embedded in the inner ring of the bearing, and the ball spline 22 is rotatably connected to the second mounting base 7 through the bearing. The axial direction of the through hole is the same as the X direction.

[0061] To further explain, the first support seat 9 is located below the mounting plate 11 in the Z direction. This can also be understood as the first support seat 9 being located below the first mounting seat 6 and the second mounting seat 7 in the Z direction. The mounting plate 11 and the first support seat 9 are slidably connected by the first sliding assembly 12. The first sliding assembly 12 can provide guidance for the mounting plate 11 to move relative to the first support seat 9 in the X direction. In other words, it improves the smoothness of the movement of the first mounting seat 6 and the second mounting seat 7 in the X direction, and in other words, it can improve the smoothness of the movement of the tensioning shaft 5 in the X direction.

[0062] In an optional embodiment, the unwinding mechanism 100 further includes a second drive component 3, the output end of which is connected to the mounting plate 11. The second drive component 3 can drive the mounting plate 11 to move along the X direction. By providing power output through the second drive component 3, the position of the tensioning shaft 5 in the X direction can be adjusted to achieve the correction function.

[0063] In one optional embodiment, the second drive assembly 3 includes a second drive member 31 and a connector 32. The second drive member 31 is disposed on the first support base 9. One end of the connector 32 is connected to the output end of the second drive member 31, and the other end of the connector 32 is connected to the mounting plate 11. The second drive member 31 can drive the first mounting base 6 and the second mounting base 7 to move in the X direction through the connector 32 and the mounting plate 11.

[0064] like Figure 2 and 6 As shown, the second drive assembly 3 includes a second drive member 31 and a connector 32. The second drive member 31 is disposed on the first support seat 9, that is, the second drive member 31 is located below the mounting plate 11 in the Z direction. One end of the connector 32 is connected to the output end of the second drive member 31, and the other end of the connector 32 is connected to the mounting plate 11. The second drive member 31 can drive the mounting plate 11 to move relative to the first support seat 9 in the X direction through the connector 32. The mounting plate 11 can drive the first mounting seat 6 and the second mounting seat 7 to move in the X direction. Therefore, the ball spline 22 can move relative to the output shaft 211 in the X direction, and the tensioning shaft 5 also moves in the X direction to achieve the correction function.

[0065] The second driving member 31 is located below the mounting plate 11 in the Z direction. On the one hand, this makes the structure of the unwinding mechanism 100 more compact. On the other hand, the second driving member 31 is also located below the first sliding component 12. When the second driving member 31 drives the mounting plate 11 to move, the mounting plate 11 moves relative to the first sliding component 12 in the X direction. This reduces the force arm of the mounting plate 11 relative to the first sliding component 12, thereby reducing the reverse torque and improving the smoothness of the movement of the mounting plate 11 in the X direction.

[0066] In one specific implementation, the second drive element 31 may be a linear motor, a hydraulic cylinder, or a pneumatic cylinder.

[0067] In one alternative implementation, such as Figure 6 As shown, the second drive assembly 3 further includes a first limiting part 33 and a second limiting part 34. The first limiting part 33 and the second limiting part 34 are spaced apart from each other along the X direction on the first support base 9. The output end of the second drive member 31 is located between the first limiting part 33 and the second limiting part 34. The output end of the second drive member 31 moves between the first limiting part 33 and the second limiting part 34, thereby limiting the range of movement of the tensioning shaft 5 in the X direction.

[0068] In an optional embodiment, the unwinding mechanism 100 further includes a third mounting base 8, a second support base 10, a second sliding assembly 13, and a connecting rod assembly 1. The third mounting base 8 is spaced apart from the first mounting base 6 along the X direction. The second support base 10 is located below the third mounting base 8. The second support base 10 and the third mounting base 8 are slidably connected through the second sliding assembly 13. One end of the connecting rod assembly 1 is connected to the mounting plate 11, and the other end of the connecting rod assembly 1 is connected to the second mounting base 7.

[0069] The tensioning shaft 5 includes a first end 52 and a second end 53. The first end 52 is rotatably connected to the first mounting base 6, and the second end 53 is rotatably connected to the third mounting base 8.

[0070] like Figure 3 and Figure 7As shown, the unwinding mechanism 100 also includes a third mounting base 8, a second support base 10, a second sliding assembly 13, and a connecting rod assembly 1. The third mounting base 8 and the first mounting base 6 are spaced apart in the X direction, and the first mounting base 6 is located between the third mounting base 8 and the second mounting base 7 in the X direction. The second support base 10 and the first support base 9 are spaced apart in the X direction, and the second support base 10 is located below the third mounting base 8. It can be understood that the second support base 10 is located below the third mounting base 8 in the Z direction. The third mounting base 8 and the second support base 10 are connected by the second sliding assembly 13. That is, the second sliding assembly 13 can provide guidance for the movement of the third mounting base 8 relative to the second support base 10 in the X direction. The first end 52 of the tensioning shaft 5 is rotatably connected to the first mounting base 6, and the second end 53 of the tensioning shaft 5 is rotatably connected to the second mounting base 7. The second sliding assembly 13 can improve the smoothness of the movement of the third mounting base 8 in the X direction. The first mounting base 6 and the third mounting base 8 together provide support for the tensioning shaft 5 in the Z direction to improve the load capacity of the tensioning shaft 5.

[0071] To further explain, one end of the linkage assembly 1 is connected to the mounting plate 11, and the other end of the linkage assembly 1 is connected to the third mounting seat 8. When the second drive assembly 3 drives the mounting plate 11 to move in the X direction, the third mounting seat 8 will move in the X direction under the action of the linkage assembly 1, so that the tension shaft 5 moves as a whole in the X direction. This can prevent the force from being transmitted to the tension shaft 5 when the second drive assembly 3 drives the mounting plate 11 to move in the X direction, thereby preventing the tension shaft 5 from deforming. The linkage assembly 1 can improve the stability of the tension shaft 5, the first mounting seat 6, the second mounting seat 7, and the third mounting plate 11 in the X direction.

[0072] In one optional embodiment, the first mounting base 6 includes a first mounting portion 61 and a second mounting portion 62; the first mounting portion 61 is provided with a first receiving groove 613, and the first mounting portion 61 includes a first mounting end 611 and a second mounting end 612, which are located on both sides of the first receiving groove 613; the second mounting portion 62 is provided with a second receiving groove 623, and the second mounting portion 62 includes a third mounting end 621 and a fourth mounting end 622, which are located on both sides of the second receiving groove 623; the first mounting end 611 is rotatably connected to the third mounting end 621, and the third mounting end 621 and the fourth mounting end 622 are connected by a first bolt 63; the first receiving groove 613 and the second receiving groove 623 form a first mounting groove, and the first end 52 is disposed in the first mounting groove.

[0073] like Figure 2As shown, the first mounting base 6 includes a first mounting part 61 and a second mounting part 62. The first mounting part 61 is located above the second mounting part 62 in the Z direction, and the second mounting part 62 is connected to the mounting plate 11.

[0074] The first mounting part 61 is provided with a first receiving groove 613, which faces the second mounting part 62. In the Y direction, the first mounting end 611 and the second mounting end 612 are located on both sides of the first receiving groove 613. The second mounting part 62 is provided with a second receiving groove 623, which faces the first mounting part 61. In the Y direction, the third mounting end 621 and the fourth mounting end 622 are located on both sides of the second receiving groove 623. The first mounting end 611 and the third mounting end 621 are rotatably connected. The connection between the first mounting end 611 and the third mounting end 621 is the first connection point. The first mounting part 61 can rotate around the rotation axis of the first connection point so that the second mounting end 612 and the fourth mounting end 622 abut or separate.

[0075] To further explain, the first mounting base 6 includes an open state and a closed state. In the open state, the second mounting end 612 and the fourth mounting end 622 are not in contact, and the first end 52 of the tensioning shaft 5 can be placed in the second receiving groove 623. When the open state changes to the closed state, the first mounting part 61 rotates around the rotation axis of the first connection, and the second mounting end 612 and the fourth mounting end 622 come into contact. The first receiving groove 613 and the second receiving groove 623 form a first mounting groove, and the first end 52 of the tensioning shaft 5 is located in the first mounting groove. The second mounting end 612 and the fourth mounting end 622 are connected by a first bolt 63 to lock the second mounting end 612 and the fourth mounting end 622. In this embodiment, the first mounting part 61 and the second mounting part 62 can be quickly opened and closed, which facilitates the quick installation of the tensioning shaft 5 on the first mounting base 6. In other words, it facilitates the loading or unloading of the tensioning shaft 5. Furthermore, the second mounting end 612 and the fourth mounting end 622 are connected by the first bolt 63, which provides high fastening. When the end of the tensioning shaft 5 is placed in the groove 41 of the transmission assembly 4, the first end 52 of the tensioning shaft 5 is fixed by the first mounting base 6, which can improve the stability of the tensioning shaft 5 during rotation.

[0076] In an optional embodiment, the third mounting base 8 includes a third mounting portion 81 and a fourth mounting portion 82; the third mounting portion 81 is provided with a third receiving groove 813, and the third mounting portion 81 includes a fifth mounting end 811 and a sixth mounting end 812, which are located on both sides of the third receiving groove 813; the fourth mounting portion 82 is provided with a fourth receiving groove 823, and the fourth mounting portion 82 includes a seventh mounting end 821 and an eighth mounting end 822, which are located on both sides of the fourth receiving groove 823; the fifth mounting end 811 is rotatably connected to the seventh mounting end 821, the sixth mounting end 812 is connected to the eighth mounting end 822 by a second bolt 83, the third receiving groove 813 and the fourth receiving groove 823 form a second mounting groove, and the second end 53 is disposed in the second mounting groove.

[0077] like Figure 3 As shown, the third mounting base 8 includes a third mounting part 81 and a fourth mounting part 82. The third mounting part 81 is located above the fourth mounting part 82 in the Z direction. The fourth mounting part 82 is slidably connected to the second support base 10 through the second sliding assembly 13.

[0078] like Figure 4 As shown, the third mounting part 81 is provided with a third receiving groove 813, which faces the fourth mounting part 82. In the Y direction, the fifth mounting end 811 and the sixth mounting end 812 are located on both sides of the third receiving groove 813. The fourth mounting part 82 is provided with a fourth receiving groove 823, which faces the third mounting part 81. In the Y direction, the seventh mounting end 821 and the eighth mounting end 822 are located on both sides of the fourth receiving groove 823. The fifth mounting end 811 and the seventh mounting end 821 are rotatably connected. The connection between the fifth mounting end 811 and the seventh mounting end 821 is the second connection point. The third mounting part 81 can rotate around the rotation axis of the second connection point so that the sixth mounting end 812 and the eighth mounting end 822 abut or separate.

[0079] Further explanation: The third mounting base 8 includes an open state and a closed state. In the open state, the sixth mounting end 812 and the eighth mounting end 822 are not in contact, allowing the second end 53 of the tensioning shaft 5 to be placed in the fourth receiving groove 823. When the open state changes to the closed state, the third mounting part 81 rotates around the rotation axis of the second connection, and the sixth mounting end 812 contacts the eighth mounting end 822. The third receiving groove 813 and the fourth receiving groove 823 form a second mounting groove, and the second end 53 of the tensioning shaft 5 is located in the second mounting groove. The sixth mounting end 812 and the eighth mounting end 822 are connected by a second bolt 83 to lock the sixth mounting end 812 and the eighth mounting end 822. In this embodiment, the third mounting part 81 and the fourth mounting part 82 can be quickly opened and closed, facilitating the quick installation of the tensioning shaft 5 on the second mounting base 7. In other words, it facilitates the loading or unloading of the tensioning shaft 5. Furthermore, the connection between the sixth mounting end 812 and the eighth mounting end via the second bolt 83 provides high tightness, improving the stability of the tensioning shaft 5 during rotation.
