[0037] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0038] The following refers to Figures 1 - 8 Describe the multi-wire harness tensioning device 100 and the film separation system of the embodiments of the present invention.

[0039] The multi-wire harness tensioning device 100 of the embodiments of the present invention includes a mounting bracket 1, a rotating shaft 2 and a plurality of winches 3.

[0040] The rotating shaft 2 is rotatably arranged on the mounting bracket 1; a plurality of winches 3 are sleeved on the rotating shaft 2 at intervals along the width extension direction of the mounting bracket 1 of the rotating shaft 2 (for example, Figure 1 The left-right direction shown in the figure), and a plurality of winches 3 can respectively wind a plurality of wire harnesses 200 on the disk body of the winch 3 so as to drive a plurality of winches 3 to wind the corresponding wire harnesses 200 simultaneously through the rotation of the rotating shaft 2.

[0041] In the multi-wire harness tensioning device 100 of the embodiments of the present invention, by arranging a plurality of winches 3 on the same rotating shaft 2, and a plurality of winches 3 can respectively wind a plurality of wire harnesses 200 on the disk body of the winch 3, a plurality of winches 3 can simultaneously tension a plurality of wire harnesses 200, avoiding the problems of low adjustment efficiency and high adjustment equipment cost caused by separately arranging tensioning members. Thus, the multi-wire harness tensioning device 100 has the advantage of high operating efficiency of the tensioning operation.

[0042] Therefore, the multi-wire harness tensioning device 100 of the embodiment of the present utility model has the advantage of improving the tensioning efficiency of the wire harness 200.

[0043] Specifically, the rotating shaft 2 extends along Figure 1 the left-right direction shown in the figure. A plurality of winches 3 are arranged on the rotating shaft 2 at intervals along the extending direction of the rotating shaft 2 and rotate with the rotation of the rotating shaft 2.

[0044] As Figure 1 、 Figure 3 and Figure 5 shown, the multi-wire harness tensioning device 100 of the embodiment of the present utility model further includes a plurality of pulley groups 4. The pulley groups 4 are arranged on the mounting bracket 1, and the wire harness 200 extending outward from the winch 3 is adapted to be lapped on the pulley groups 4. It can be understood that at least a part of the wire harness 200 is wound on the winch 3 at the corresponding position.

[0045] For the multi-wire harness tensioning device 100 of the embodiment of the present utility model, by arranging a plurality of pulley groups 4, it is helpful to position and guide the corresponding wire harness 200, and it can have a certain pre-tightening effect, thereby preventing the problem of chaos of the wire harness 200 when the wire harness 200 is in a relaxed state, and helping to solve the tensioning problem of different required tensions of different wire harnesses 200 in the winding and unwinding system of multiple wire harnesses 200 at the same time. Thus, the multi-wire harness tensioning device 100 has an improved tensioning effect on the wire harness 200.

[0046] As Figure 4 、 Figure 6 and Figure 8 shown, the pulley group 4 includes a first fixed pulley 41, a movable pulley 42 and a second fixed pulley 43. Each of the first fixed pulley 41 and the second fixed pulley 43 has a height difference from the movable pulley 42 in the height direction of the mounting bracket 1. The first fixed pulley 41 and the second fixed pulley 43 are rotatably fixed on the mounting bracket 1, and the movable pulley 42 is movably arranged relative to the mounting bracket 1 along the height direction of the mounting bracket 1. One end of each wire harness 200 is wound around the winch 3, and the wire harness 200 is adapted to be sequentially lapped on the first fixed pulley 41, the movable pulley 42 and the second fixed pulley 43

[0047] It can be understood that after one end of the corresponding wire harness 200 is wound by the winch 3, the wire harness 200 bypasses the first fixed pulley 41, the movable pulley 42 and the second fixed pulley 43 and then is lapped on the wire harness positioning bracket 300.

[0048] The multi-wire harness tensioning device 100 according to an embodiment of the present utility model divides the pulley block 4 into a first fixed pulley 41, a movable pulley 42, and a second fixed pulley 43, and the movable pulley 42 is movably arranged relative to the mounting bracket 1 along the height direction of the mounting bracket 1. The movement of the movable pulley 42 can adjust the tension of the corresponding wire harness 200 by dividing the wire harness 200, adapting to the adjustment of different slack wire harnesses 200. Thus, the multi-wire harness tensioning device 100 according to an embodiment of the present utility model has the advantage of good applicability.

[0049] For example, when the pulling forces of multiple wire harnesses 200 are basically the same, the tension is directly adjusted uniformly by rotating the rotating shaft 2. When the pulling forces between the wire harnesses 200 differ greatly, the position of the movable pulley 42 can be adjusted to adjust the pulling of the wire harness 200. Then, the tension is adjusted uniformly by rotating the rotating shaft 2. It is also possible to first make a rough adjustment by rotating the rotating shaft 2, and then tension the slack wire harness 200 among them.

[0050] As Figure 4 、 Figure 6 and Figure 8 shown, the multi-wire harness tensioning device 100 according to an embodiment of the present utility model further includes a movable pulley frame 5. The movable pulley 42 is rotatably arranged on the movable pulley frame 5. One of a guide groove and a guide projection 14 is provided on the mounting bracket 1, and the other of the guide groove and the guide projection 14 is provided on the movable pulley frame 5. The guide projection 14 is in guiding sliding fit with the guide groove. In other words, a guide groove is provided on the mounting bracket 1, and a guide projection 14 is provided on the movable pulley frame 5. A guide projection 14 is provided on the mounting bracket 1, and a guide groove is provided on the movable pulley frame 5.

[0051] The multi-wire harness tensioning device 100 according to an embodiment of the present utility model, by providing the movable pulley frame 5 that is in guiding sliding fit with the mounting bracket 1 by means of the guide projection 14 and the guide groove, avoids the swing of the movable pulley 42 during the movement, that is, only makes the movable pulley 42 move reciprocally in the up and down direction. Thus, the multi-wire harness tensioning device 100 according to an embodiment of the present utility model helps to improve the stability of the pulley block 4.

[0052] As Figure 4 、 Figure 6 and Figure 8 shown, the multi-wire harness tensioning device 100 according to an embodiment of the present utility model further includes an elastic pulling member 6. The mounting bracket 1 is provided with a pulling positioning point. The pulling positioning point and each of the first fixed pulley 41 and the second fixed pulley 43 are arranged on both sides of the movable pulley 42 in the height direction of the mounting bracket 1. One end of the elastic pulling member 6 is connected to the movable pulley frame 5, and the other end of the elastic pulling member 6 is connected to the pulling positioning point, so as to limit the movement of the movable pulley 42.

[0053] The multi-wire harness tensioning device 100 according to the embodiment of the present utility model can provide a certain pulling force for the tensioning of the corresponding wire harness 200 through the provided elastic pulling member 6. When the pulling force is constant, the tension between different wire harnesses 200 is also prone to consistent deformation. Furthermore, the difference in tension between different wire harnesses 200 is compensated. That is, when the tension difference between multiple wire harnesses 200 is not large, it can be compensated by the pulling force of the elastic pulling member 6.

[0054] Furthermore, there can be multiple pulling and positioning points. The consistent deformation of the elastic pulling member 6 indicates that it can provide the same pulling force, thereby ensuring the consistency of the tension between different wire harnesses 200. When the deformation of the elastic pulling member 6 is inconsistent and the distance between the movable pulley 42 and the first fixed pulley 41 and the second fixed pulley 43 differs significantly, the position of the pulling and positioning point at the other end of the elastic pulling member 6 can be adjusted simultaneously. Thus, the multi-wire harness tensioning device 100 according to the embodiment of the present utility model helps to further reduce the difference in the pulling force between different wire harnesses 200.

[0055] Optionally, the elastic pulling member 6 can be a tension spring.

[0056] As Figure 4 、 Figure 6 and Figure 8 shown, the multi-wire harness tensioning device 100 according to the embodiment of the present utility model further includes a positioning runner 44. The positioning runner 44 is arranged between the first fixed pulley 41 and the second fixed pulley 43 in the thickness direction of the mounting bracket 1, and a first wire groove 45 is provided between the positioning runner 44 and the first fixed pulley 41, and a second wire groove 46 is provided between the positioning runner 44 and the second fixed pulley 43. The wire harness 200 is threaded through the first wire groove 45 and the second wire groove 46, and the positioning runner 44, the first fixed pulley 41, and the second fixed pulley 43 are all in contact with the wire harness 200. It can be understood that the central rotation shafts 2 of the positioning runner 44, the first fixed pulley 41, and the second fixed pulley 43 are arranged in parallel.

[0057] The multi-wire harness tensioning device 100 according to the embodiment of the present utility model, through the positioning runner 44 arranged between the first fixed pulley 41 and the second fixed pulley 43, the positioning runner 44, the first fixed pulley 41, and the second fixed pulley 43 are all in contact with the wire harness 200. Thus, the wire harness 200 can be further positioned, and furthermore, the problem of the wire harness 200 running off is prevented.

[0058] As Figure 4 、 Figure 6 and Figure 8 shown, the positioning runner 44, the first fixed pulley 41, and the second fixed pulley 43 can be arranged at the same height. Thus, the positioning and twisting effect on the wire harness 200 is further improved.

[0059] As Figure 1 、Figure 3 and Figure 5 As shown in Figure 5 , the mounting bracket 1 includes a support frame 11, and a first bearing block 12 and a second bearing block 13 provided on both sides in the width direction of the support frame 11. Both ends of the rotating shaft 2 are rotatably fitted on the first bearing block 12 and the second bearing block 13 respectively.

[0060] For the multi-wire harness tensioning device 100 of the embodiment of the present utility model, both ends of the rotating shaft 2 are fixed by the first bearing block 12 and the second bearing block 13 provided on the support frame 11. Thus, the multi-wire harness tensioning device 100 of the embodiment of the present utility model has the advantage of good structural stability.

[0061] As Figure 1 、 Figure 3 and Figure 5 shown, the multi-wire harness tensioning device 100 of the embodiment of the present utility model further includes a driving member 7. The driving member 7 includes a motor 71 and a driving wheel 72. The main body of the motor 71 is connected to the support frame 11, the driving wheel 72 is provided on the output shaft of the motor 71, and the driving wheel 72 is cooperated with the rotating shaft 2 through a belt.

[0062] For the multi-wire harness tensioning device 100 of the embodiment of the present utility model, by providing the driving member 7, the driving of the rotating shaft 2 can be realized. Thus, the multi-wire harness tensioning device 100 of the embodiment of the present utility model has the advantage of high degree of mechanization. In addition, the driving wheel 72 is provided on the output shaft of the motor 71, and the driving wheel 72 is cooperated with the rotating shaft 2 through a belt. Thus, the multi-wire harness tensioning device 100 of the embodiment of the present utility model has the advantage of good transmission stability.

[0063] Optionally, the driving member 7 can also be cooperated with a magnetic powder clutch 8 and the motor 71 to adjust the tension of winding and unwinding.

[0064] The embodiment of the present utility model is not limited thereto. For example, in other embodiments, the rotating shaft 2 can also be manually driven by a handle.

[0065] Further, a limiting hole is provided on the support frame 11, and the motor 71 is embedded in the limiting hole. Thus, the multi-wire harness tensioning device 100 has the advantage of good structural stability.

[0066] The film material separation system of the embodiment of the present utility model includes a plurality of wire harnesses 200, a wire harness positioning frame 300, and the multi-wire harness tensioning device 100 according to any one of the above. The wire harness positioning frame 300 is connected to the mounting bracket 1, and the wire harness 200 has a film material fixing point for film tearing.

[0067] The film material separation system of the embodiment of the present utility model has the advantage of improving the tensioning efficiency of the wire harness 200.

[0068] Optionally, the wire harness 200 can be a flexible linear or strip-shaped article such as a wire, a tape, a film, etc.

[0069] As Figure 1 , Figure 3 and Figure 5 shown, there are at least two wire harness positioning frames 300, and the number of the multi-wire harness tensioning devices 100 is 2. The two multi-wire harness tensioning devices 100 are mirror-symmetrically arranged at intervals along the length direction of the film separating system (for example, Figure 1 the front-back direction shown in

[0070] is the thickness direction of the mounting bracket 1). Among them, the two wire harness positioning frames 300 are correspondingly arranged on the two mounting brackets 1. The tops of the two wire harness positioning frames 300 each have a plurality of wire harness rollers 301. Each wire harness 200 is laid on the corresponding wire harness roller 301. The two ends of the wire harness 200 are respectively wound on the winches 3 of the two multi-wire harness tensioning devices 100, so as to realize the winding of the wire harness 200.

[0071] Working principle of the film material separation system according to the embodiment of the present utility model: Define the two multi-wire harness tensioning devices 100 as the unwinding side and the winding side respectively. When the rotating shaft 2 on the unwinding side rotates clockwise, the winch 3 on the rotating shaft 2 is driven to rotate through the belt, and the wire harness 200 is released from the reel on the unwinding side. While the motor 71 on the winding side rotates counterclockwise synchronously, driving the winch 3 on the winding side to rotate, and tightening the wire harness 200 released from the unwinding side. During this process, the single-wire harness 200 tensioning pulley group 4 installed between the two winches 3 tensions the wire harness 200 through the stretching of the spring. When multiple wire harnesses 200 are simultaneously unwound and wound in this system, due to the plastic deformation of the wire harness 200 itself or the error of the release linear velocity, the lengths of each wire harness 200 may gradually become different, resulting in different tensions required to tension the wire harness 200. This compensates for the tension required when tensioning the wire harness 200 by the different stretching lengths of the spring, so that each wire harness 200 can be tensioned. The film material fixing points on the wire harness 200 can cooperate with the segregation of the film material to drag a part of the film to play a role in tearing the film.
