Obviously, the described embodiments are some but not all of the embodiments of the present application.

It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in any manner without conflict.
[0027] The current manual winding device often needs at least two operators when in use. When the winding frame needs to be stopped at a position for an operator to tie a knot or perform other operations, another operator usually needs to hold the winding frame to facilitate the operation of the operator, which wastes human resources, and the manual fixing of the position is unstable, and the produced sample is not uniform, which may affect the accuracy of the mechanical property test result.
[0028] To solve the above problems, a protruding structure is arranged on the winding frame, a buckle structure is correspondingly arranged on the support, the protruding structure on the winding frame and the buckle structure on the support are clamped, and the position of the winding frame is fixed. The protruding structure on the winding frame is arranged to be rotatable in the buckle structure, the winding frame is rotated, the position of the winding frame does not need to be manually fixed, human resources are saved, the stability of the position fixing is ensured, and the production efficiency is improved.
[0029] The winding device provided by the present application will be described in detail below with reference to the drawings.
[0030] It should be noted that the vertical direction in the present application is the direction of the z-axis in the figure, and in addition, Figure 1 In order to distinguish different elastic sheets, a gap is left between the elastic sheets, which is only a structural schematic diagram and does not contradict the actual abutting relationship of the two elastic sheets. Figure 2 An exemplary embodiment of the present application provides a winding device, as shown in the figure, the winding device comprises a winding frame 100 and a support 200, the support 200 is used for supporting the winding frame 100, the winding frame 100 is used for winding fibers, and the winding frame 100 is provided with a protruding structure 110 on each of the opposite sides. Two buckle structures 210 are arranged on the support 200, the distance between the buckle structure 210 and the ground is sufficient for the winding frame 100 to rotate; the protruding structure 110 can be clamped in the buckle structure 210, and the protruding structure 110 can also rotate in the buckle structure 210.
[0031] Figure 1
[0032] By setting the protruding structure 110 on the winding frame 100, setting the buckle structure 210 on the support 200 correspondingly, and clamping the protruding structure 110 on the winding frame 100 and the buckle structure 210 on the support 200, the position of the winding frame 100 is fixed; the protruding structure 110 on the winding frame 100 is set to be rotatable in the buckle structure 210, and the rotation of the winding frame 100 is realized, without the need for manual fixing of the position of the winding frame 100, saving human resources, and also ensuring the stability of the fixed position and improving the production efficiency.
[0033] In some embodiments, as shown in Figure 1 and Figure 2 The buckle structure 210 includes a first opening and closing part 2110, a second opening and closing part 2120, and a connecting part 2130. The first opening and closing part 2110 and the second opening and closing part 2120 are respectively arranged at the two ends of the connecting part 2130 along the z-axis direction, i.e. the upper and lower ends. Both the first opening and closing part 2110 and the second opening and closing part 2120 have an open state and a closed state. The first opening and closing part 2110 has a first open state and a first closed state, and the second opening and closing part 2120 has a second open state and a second closed state.
[0034] When the first opening and closing part 2110 is in the first closed state and the second opening and closing part 2120 is in the second closed state, the first opening and closing part 2110, the connecting part 2130, and the second opening and closing part 2120 together enclose a cavity 2140 of the buckle structure 210, which is used for clamping and rotating the protruding structure 110. When the first opening and closing part 2110 is in the first open state, the protruding structure 110 can be clamped into the cavity 2140 through the first opening and closing part 2110. When the second opening and closing part 2120 is in the second open state, the protruding structure 110 can be separated from the cavity 2140 through the second opening and closing part 2120.
[0035] By setting the first open state of the first opening and closing part 2110 and the second open state of the second opening and closing part 2120, the winding frame 100 can be installed on the support 200 and separated from the support 200. The operator in the field can replace the winding frame 100 of different models according to actual needs to prepare test samples of different models. By setting the first closed state of the first opening and closing part 2110 and the second closed state of the second opening and closing part 2120, the cavity 2140 enclosed by the first opening and closing part 2110, the connecting part 2130, and the second opening and closing part 2120 can be used for clamping and rotating the protruding structure 110. At this time, the first opening and closing part 2110 and the second opening and closing part 2120 can also play a protective role, preventing foreign matter from entering the inside of the cavity 2140 and ensuring the cleanliness of the inside of the buckle structure 210.
[0036] In some embodiments, continuing to refer to Figure 2The first opening and closing portion 2110 includes a first elastic piece 2111 and a second elastic piece 2112. The first end of the first elastic piece 2111 is hinged to the connecting portion 2130 through a first torsion spring 2113. The first torsion spring 2113 is used to provide a torque for the first elastic piece 2111 to rotate toward the outside of the cavity 2140. The outside of the cavity 2140 is the direction of rotation. Figure 2 The first spring 2111 rotates in the clockwise direction; the first end of the second spring 2112 is fixedly connected to the connecting portion 2130. In the natural state, the second end of the first spring 2111 abuts against the inner side surface of the second end of the second spring 2112 under the action of the first torsion spring 2113. It should be noted that the natural state here refers to the state in which the first spring 2111 and the second spring 2112 are not subjected to any external force.
[0037] In this embodiment, the length of the first elastic piece 2111 is greater than that of the second elastic piece 2112. In this case, in a natural state, the second elastic piece 2112 can provide better support for the first elastic piece 2111, thereby better supporting the protruding structure 110 when the protruding structure 110 is engaged with the buckle structure 210, thereby supporting the entire winding frame 100. Of course, in other embodiments, the length of the first elastic piece 2111 can also be slightly greater than or less than the length of the second elastic piece 2112, which is not limited here.
[0038] With such a design, under the action of the first torsion spring 2113, the first spring piece 2111 can only rotate from its initial position in the natural state toward the cavity 2140, but cannot rotate from the initial position toward the direction away from the cavity 2140, so that when the protruding structure 110 enters the cavity 2140 from the first opening and closing portion 2110, the first spring piece 2111 that is driven to rotate into the cavity 2140 returns to its initial position under the action of the first torsion spring 2113, and provides support force to the protruding structure 110 in the locked state in the cavity 2140.
[0039] In some embodiments, as Figure 2 As shown, the second opening and closing portion 2120 includes a third elastic piece 2121 and a fourth elastic piece 2122. The first end of the third elastic piece 2121 and the first end of the fourth elastic piece 2122 are respectively hinged to the connecting portion 2130. In a natural state, the second end of the third elastic piece 2121 and the second end of the fourth elastic piece 2122 abut each other. It should be noted that the abutment between the third elastic piece 2121 and the fourth elastic piece 2122 can be at the end surfaces of the distal ends, or the outer side surface of the third elastic piece 2121 and the inner side surface of the fourth elastic piece 2122 can abut each other. In addition, the third elastic piece 2121 and the fourth elastic piece 2122 can be configured to open and close in only one direction, or can be configured to open and close in both directions, both inside and outside the cavity 2140, all of which are within the scope of protection of this application.
[0040] In some embodiments, continue to refer to Figure 2The third elastic sheet 2121 and the fourth elastic sheet 2122 are both in a circular arc structure and have the same radius. The first end of the third elastic sheet 2121 is hinged to the connecting part 2130 through a second torsion spring 2123, and the first end of the fourth elastic sheet 2122 is hinged to the connecting part 2130 through a third torsion spring 2124. The second torsion spring 2123 is used to provide a torque to the third elastic sheet 2121 in the direction of the inside of the cavity 2140, and the third torsion spring 2124 is used to provide a torque to the fourth elastic sheet 2122 in the direction of the inside of the cavity 2140.
[0041] In this way, under the action of the second torsion spring 2123, the third elastic sheet 2121 can only rotate away from the cavity 2140 from the initial position in the natural state, and cannot rotate towards the cavity 2140 from the initial position. The fourth elastic sheet 2122 is the same. Therefore, when the protruding structure 110 moves away from the cavity 2140 from the second opening and closing part 2120, the third elastic sheet 2121 rotated outwards of the cavity 2140 returns to the initial position under the action of the second torsion spring 2123, and the fourth elastic sheet 2122 rotated outwards of the cavity 2140 returns to the initial position under the action of the third torsion spring 2124. In addition, the circular arc-shaped third elastic sheet 2121 and the fourth elastic sheet 2122 can reduce the space occupied by the buckle structure 210.
[0042] In some embodiments, as shown in Figure 2 The radius of the circular arc-shaped third elastic sheet 2121 and the fourth elastic sheet 2122 is greater than half the length of the longest side of the protruding structure 110, so as to ensure that the space of the cavity 2140 can provide rotation for the protruding structure 110.
[0043] In another embodiment, the third elastic sheet 2121 and the fourth elastic sheet 2122 can also be provided as a planar structure similar to the first elastic sheet 2111 and the second elastic sheet 2112. At this time, the length of the connecting part 2130 in the z-axis direction needs to be greater than the length of the longest side of the protruding structure 110 to provide sufficient space for the protruding structure 110 to rotate.
[0044] In some embodiments, as shown in Figure 2 The connecting part 2130 is in a cylindrical structure, and the shape of the end of the connecting part 2130 close to the first opening and closing part 2110 is adapted to the shape of the protruding structure 110 to limit the winding frame 100. Adaptation means that the cross-sectional shape of the connecting part 2130 is the same as the shape of the protruding structure 110, or the cross-sectional shape of the connecting part 2130 is slightly larger than the cross-sectional shape of the protruding structure 110 in the cross-sectional plane perpendicular to the z-axis direction. When the protruding structure 110 is clamped here, it is ensured that the winding frame 100 will not shake, and stable fixation is achieved.
[0045] It should be noted that the two connecting portions 2130 of the two buckle structures 210 are provided with through holes on the opposite two faces, so as to connect the protruding structure 110 and the winding frame 100.
[0046] In some embodiments, as shown in Figure 3 The length of the connecting portion 2130 in the vertical direction is greater than half of the length of the longest side of the protruding structure 110, so as to ensure that the protruding structure 110 has sufficient space for rotation.
[0047] In some embodiments, as shown in Figure 1 The winding frame 100 includes two first frames 120 and two second frames 130, the two first frames 120 and the two second frames 130 form a rectangular frame, the two protruding structures 110 are oppositely arranged on the middle sections of the two first frames 120, and the two second frames 130 are used for winding fibers. The frame-shaped winding frame 100 helps to reduce the weight of the winding frame 100 and save labor costs.
[0048] In some embodiments, as shown in Figure 1 The support 200 includes a base 220 and two support rods 230, the two support rods 230 are oppositely arranged on the base 220 and extend in the vertical direction, the distance between the two support rods 230 is slightly greater than the length of the second frame 130, and the buckle structure 210 is arranged on the support rod 230. The distance between the two support rods 230 is slightly greater than the length of the second frame 130, which means that when the protruding structure 110 on the winding frame 100 is clamped into the buckle structure 210 on the support rod 230, the winding frame 100 will not sway left and right between the two in the x-axis direction, ensuring the stability of the support. Figure 2
[0049] In some embodiments, as shown in The protruding structure 110 is a cuboid structure, the plane of which can ensure the stability of the clamping and is simple to process. The plane on which the protruding structure 110 is arranged can form a set angle with the plane on which the winding frame 100 is arranged, so as to ensure that one end of the winding frame 100 is low and the other end is high in the clamped state, facilitating the operator to operate at the low end.
[0050] The use process of the above winding device is as follows:
[0051] The operator inserts the protruding structure 110 from the first opening and closing part 2110 into the buckle structure 210, and makes the buckle structure 210 clamped with the protruding structure 110, so that the winding frame 100 is in a stable state. After fixing one end of the fiber on the winding frame 100, the operator lifts the winding frame 100 and starts to rotate the winding frame 100 manually, and completes the winding of the fiber. When the winding frame 100 needs to stop at a preset position to knot the fiber, the operator puts down the winding frame 100, and the protruding structure 110 is re-inserted into the connecting part 2130 close to one end of the first opening and closing part 2110 under the action of gravity, and the operator operates. Repeat the operation according to the above steps to finally complete the production of the sample.
[0052] The winding device provided by the application realizes the fixing and rotation of the winding frame 100 by setting the protruding structure 110 on the winding frame 100 and correspondingly setting the buckle structure 210 on the support 200, and the clamping and rotation of the protruding structure 110 and the buckle structure 210 in the cavity 2140. The first opening and closing part 2110 and the second opening and closing part 2120 provide an entrance and an exit for the protruding structure 110 to enter and exit, and the first opening and closing part 2110 can also provide support force for the protruding structure 110. Through the above setting, the position of the winding frame 100 does not need to be fixed manually, which saves human resources, ensures the stability of the fixed position, and improves the production efficiency.
