In the present application, the illustrative description of the above terms does not necessarily mean the same embodiment or embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or embodiments in a suitable manner.

[0034] The terms "first", "second", etc. are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features.

[0035] As Figures 1-8As shown, the embodiment of the present application provides a composite current collector traction device, which comprises a cooling roller 2, an annular cavity 3, a first cavity 31, a second cavity 32, two arc-shaped plates 6, a sleeve 26, an adjusting mechanism, a lifting mechanism and a water cooling mechanism 23. The annular cavity 3 is coaxially arranged in the inside of the cooling roller 2. The two arc-shaped plates 6 are symmetrically arranged on both sides of the annular cavity 3, and the space between the upper ends and the bottom ends of the two arc-shaped plates 6 is the second cavity 32 and the first cavity 31 respectively. The first cavity 31 is filled with hydraulic oil. The adjusting mechanism fills or removes the hydraulic oil in the first cavity 31, so as to drive the two arc-shaped plates 6 to synchronously rotate around the axis of the annular cavity 3 in the same direction or in the opposite direction, so as to adjust the size of the second cavity 32. The water cooling mechanism 23 is used for conveying circulating cooling water into the second cavity 32. The lifting mechanism is arranged at both ends of the cooling roller 2, and is used for vertically lifting the cooling roller 2 and simultaneously adjusting the size of the second cavity 32. The sleeve 26 is rotatably arranged on the outer surface of the cooling roller 2.

[0036] In the embodiment, the traction shaft is used for traction conveying of the composite current collector. The composite current collector passes through the upper surface of the cooling roller 2 for cooling. When the composite current collector needs to be tensioned, the lifting mechanism drives the cooling roller 2 to vertically lift, so as to tension the composite current collector by adjusting the height of the cooling roller 2. The lifting mechanism is started at the same time, and the adjusting mechanism is triggered to start. The adjusting mechanism fills or removes the hydraulic oil in the first cavity 31, so as to drive the two arc-shaped plates 6 to synchronously rotate around the axis of the annular cavity 3 in the same direction or in the opposite direction, so as to adjust the size of the second cavity 32 to be larger or smaller.

[0037] Since the composite current collector is in close contact with the upper surface of the cooling roller 2 for tensioning, when the cooling roller 2 is lifted, the size of the close contact angle between the composite current collector and the upper surface of the cooling roller 2 changes. When the cooling roller 2 is lifted, the close contact angle becomes larger. When the cooling roller 2 is lowered, the close contact angle becomes smaller.

[0038] When the close contact angle becomes larger, the size of the second cavity 32 becomes larger. When the close contact angle becomes smaller, the size of the second cavity 32 becomes smaller.

[0039] The water cooling mechanism 23 is used for conveying circulating cooling water into the second cavity 32, so as to cool and lower the temperature of the sleeve 26, and then cool and lower the temperature of the composite current collector.

[0040] The size of the second cavity 32 is adaptively adjusted when the cooling roller 2 is lifted, so that the cooling water flows through the heat conduction surface, the concentrated water flow lowers the temperature of the heat conduction surface, and the cooling is accelerated. The traditional tensioning and water cooling processes are combined, and the structure is simplified. The problem of low cooling efficiency and waste of water cooling resources caused by the traditional spiral flow channel which cools the entire inside of the traction shaft and cannot concentrate on the heat conduction surface is solved.

[0041] As shown in the figure, Figure 6 , Figure 7 and Figure 8As shown, optionally, the inner wall of the bottom end of the first chamber 31 is fixedly connected with a fixed plate 4, the fixed plate 4 divides the first chamber 31 into two mutually symmetrical spaces, the outer sides of the two arc-shaped plates 6 are matched and slid on the inner surface of the annular cavity 3, the bottom end of the arc-shaped plate 6 is fixedly connected with the side of the corresponding fixed plate 4, the bending spring 5 is telescopic along the arc-shaped track of the first chamber 31, the inside of the fixed plate 4 is provided with an oil delivery hole 7, a plurality of uniformly distributed oil passing holes 8 are symmetrically provided in the two inner side walls of the oil delivery hole 7 along the axis direction, and the oil passing holes 8 are in communication with the first chamber 31.

[0042] In the embodiment, the first chamber 31 is filled with hydraulic oil, the external hydraulic oil is input into the oil delivery hole 7, and then the hydraulic oil enters into the corresponding first chamber 31 through the oil passing holes 8 on the two sides. The increase of the hydraulic oil in the two first chambers 31 will push the upper ends of the arc-shaped plates 6 on the two sides to synchronously rotate towards each other, at this time, the space in the second chamber 32 becomes smaller, and the bending springs 5 on the two sides are stretched. If the hydraulic oil in the first chambers 31 on the two sides flows into the oil delivery hole 7 through the oil passing holes 8 and is discharged outward, the hydraulic oil in the first chambers 31 decreases, and at the same time, the bending springs 5 on the two sides restore the deformation to pull the arc-shaped plates 6, so that the upper ends of the arc-shaped plates 6 on the two sides synchronously rotate away from each other, at this time, the space in the second chamber 32 becomes larger.

[0043] As shown in Figure 2 , Figure 3 and Figure 7 As shown, optionally, the adjusting mechanism comprises an oil pipe 9, an electromagnetic valve 10, a sleeve 11, a piston plate 12 and a connecting rod 13, the oil pipe 9 is fixedly communicated with the end of the oil delivery hole 7, the electromagnetic valve 10 is fixedly installed on the oil pipe 9, one end of the oil pipe 9 away from the oil delivery hole 7 is fixedly communicated with the middle part of the upper end of the sleeve 11, the outer side of the piston plate 12 is slidably connected with the inner side of the sleeve 11, the bottom end middle part of the piston plate 12 is fixedly connected with the upper end part of the connecting rod 13, and the space on the upper end of the piston plate 12 and the inside of the oil pipe 9 are both filled with hydraulic oil.

[0044] In the embodiment, the piston plate 12 is pushed upward by the connecting rod 13, the hydraulic oil in the space on the upper end of the piston plate 12 moves upward and squeezes the hydraulic oil in the oil pipe 9 to enter into the oil delivery hole 7. When the piston plate 12 is driven by the connecting rod 13 to move downward, the space on the upper end of the piston plate 12 becomes larger, a negative pressure is generated inside, and then the hydraulic oil in the oil delivery hole 7 is extracted outward through the oil pipe 9 to fill the increased space on the upper end of the piston plate 12. The electromagnetic valve 10 realizes the on-off of the oil pipe 9.

[0045] As shown in Figure 3 Optionally, the bottom end of the sleeve 11 is open, and the space on the lower end of the piston plate 12 is communicated with the external atmospheric pressure.

[0046] In this embodiment, the lower end space of the piston plate 12 is in communication with the atmospheric pressure, which can ensure that the piston plate 12 is not hindered when lifting in the sleeve 11, and ensure that the normal oil pushing and oil pumping process is realized.

[0047] As shown in Figure 1 , Figure 3 and Figure 7 , optionally, the lifting mechanism comprises a base 1, a lifting plate 14, a fixed shaft 15, a connecting block 16, a bidirectional threaded screw rod 17, a servo motor 18, a guide rod 19 and a limiting plate 20, the cooling roller 2 is fixedly installed in the middle part of the outer periphery of the fixed shaft 15, the connecting block 16 is symmetrically fixedly connected to both ends of the fixed shaft 15, the bottom end of the guide rod 19 is fixedly connected to the upper end face of the base 1, the outer side of the guide rod 19 is slidingly connected to the inside of the corresponding connecting block 16, the servo motor 18 is fixedly installed on the upper end face of the base 1 and the output end is fixedly connected to the bottom end of the bidirectional threaded screw rod 17, the end surface of the lifting plate 14 is fixedly connected to the bottom end of the connecting rod 13, the bidirectional threaded screw rod 17 is threadedly connected to the inside of the corresponding connecting block 16, the inside of the lifting plate 14 is threadedly connected to the outside of the bidirectional threaded screw rod 17, and the lifting plate 14 and the corresponding connecting block 16 are located at the lower end and the upper end of the bidirectional threaded screw rod 17, respectively.

[0048] In this embodiment, the servo motor 18 starts and drives the bidirectional threaded screw rod 17 to rotate, drives the lifting plate 14 and the connecting block 16 to move synchronously towards or away from each other in the vertical direction, and then realizes that when the connecting block 16 drives the cooling roller 2 to rise, the lifting plate 14 moves downward, drives the piston plate 12 to move downward for oil pumping, and the space of the second chamber 32 becomes larger; when the connecting block 16 drives the cooling roller 2 to descend, the lifting plate 14 moves upward, drives the piston plate 12 to move upward for oil pumping, and the space of the second chamber 32 becomes smaller.

[0049] As shown in Figure 1 , optionally, the upper end part of the bidirectional threaded screw rod 17 and the guide rod 19 is fixedly connected with the limiting plate 20.

[0050] In this embodiment, by arranging the limiting plate 20 on the upper end part of the bidirectional threaded screw rod 17 and the guide rod 19, it is ensured that the connecting block 16 does not slip off when lifting.

[0052] In this embodiment, by setting the bearing 25, the sleeve 26 is ensured to be rotatable on the outer surface of the cooling roller 2, facilitating the composite current collector to be adhered and tensioned on the upper surface of the sleeve 26. Here, the sleeve 26 is adhered to the cooling roller 2, and it is also convenient for the composite current collector to transfer heat to the cooling roller 2 through the contact surface with the sleeve 26, so as to facilitate water cooling.

[0053] As shown in Figure 1 With Figure 7 As shown in the figure, optionally, the water cooling mechanism 23 comprises the water inlet pipe 21, the water outlet pipe 22 and a small water cooler.

The cooling roller 2 rises and the lifting plate 14 moves downward, driving the piston plate 12 to move downward to draw oil in the first chamber 31. The space of the second chamber 32 becomes larger, and the composite current collector and the sleeve 26 upper surface adhering surface becomes larger. The water cooling mechanism 23 delivers cooling water into the second chamber 32, and the concentrated water flow cools the larger adhering surface;

A method of processing a composite current collector based on the composite current collector drawing device according to any one of claims 1 to 6, characterized by, The steps are as follows: S1: the traction shaft is used for traction conveying the composite current collector, and the composite current collector passes through the upper surface of the sleeve (26) arranged on the cooling roller (2) to be cooled in the process; S2: when the composite current collector needs to be tensioned, the lifting mechanism drives the cooling roller (2) to vertically ascend, the height of the cooling roller (2) is adjusted to tension the composite current collector, the lifting mechanism is started to trigger the starting adjusting mechanism, the adjusting mechanism is started to draw away the hydraulic oil in the first chamber (31), thereby driving the two arc-shaped plates (6) to synchronously rotate away from each other, the space of the second chamber (32) is adjusted to be larger, at this time, the composite current collector is combined with the upper surface of the cooling roller (2) to have a larger croissant-shaped surface, and then the water cooling mechanism (23) is used for conveying circulating cooling water into the second chamber (32) to cool the sleeve (26), thereby cooling the composite current collector; S3: When the composite current collector is over-tensioned, the lifting mechanism drives the cooling roller (2) to vertically descend, and the over-tensioning of the composite current collector is released by adjusting the height of the cooling roller (2). The lifting mechanism is started at the same time, and the starting adjustment mechanism is triggered. The adjustment mechanism is started to fill the hydraulic oil into the first chamber (31), and then drives the two arc-shaped plates (6) to synchronously rotate towards each other. The space of the second chamber (32) becomes smaller. At this time, the composite current collector is in contact with the upper surface of the cooling roller (2), and the croissant becomes smaller. Then, the water cooling mechanism (23) is used to transport circulating cooling water into the second chamber (32) to cool the sleeve (26), and then the composite current collector is cooled and treated; S4: The cooled composite current collector is wound on the winding roller, and the work is completed.
