DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment", "some embodiments", "exemplarily" and "one embodiment" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or embodiment are included in at least one embodiment or embodiment of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or embodiment. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or embodiments in a suitable manner.

[0022] The terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0023] like Figure 1-8As shown, an embodiment of the present invention provides a composite current collector traction device, including a cooling roller 2, an annular cavity 3, a first chamber 31, a second chamber 32, two arc-shaped plates 6, a sleeve 26, an adjustment mechanism, a lifting mechanism and a water cooling mechanism 23. The annular cavity 3 is coaxially opened inside the cooling roller 2, and the two arc-shaped plates 6 are symmetrically arranged on both sides of the annular cavity 3 and the space between the upper end and the bottom end of the two are the second chamber 32 and the first chamber 31 respectively. The first chamber 31 is filled with hydraulic oil. The adjustment mechanism fills or extracts the hydraulic oil into the first chamber 31 to drive the two arc-shaped plates 6 to rotate synchronously toward or away from each other around the axis of the annular cavity 3 to adjust the size of the second chamber 32. The water cooling mechanism 23 is used to transport circulating cooling water into the second chamber 32. The lifting mechanism is mounted at both ends of the cooling roller 2 for vertical lifting and lowering of the cooling roller 2 and driving the adjustment of the size of the second chamber 32 at the same time. The sleeve 26 is rotatably sleeved on the outer surface of the cooling roller 2.

[0024] In this embodiment, the traction shaft traction transports the composite current collector, and the composite current collector passes through the upper surface of the cooling roller 2 for cooling during the process. When the composite current collector needs to be tensioned, the lifting mechanism drives the cooling roller 2 to lift vertically, and the composite current collector is tensioned by adjusting the height of the cooling roller 2. The lifting mechanism is started and the adjustment mechanism is triggered at the same time. The adjustment mechanism starts to fill or remove hydraulic oil in the first chamber 31, thereby driving the two arc plates 6 to rotate synchronously toward or away from each other around the axis of the annular cavity 3, and adjusting the space of the second chamber 32 to become larger or smaller; Since the composite current collector is tightly attached to the upper surface of the cooling roller 2, when the cooling roller 2 is raised or lowered, the size of the laminating bread angle between the composite current collector and the upper surface of the cooling roller 2 changes. When the cooling roller 2 rises, the laminating bread angle becomes larger; when the cooling roller 2 falls, the laminating bread angle becomes smaller. When the bread-fitting angle becomes larger, the space of the second chamber 32 becomes larger; when the bread-fitting angle becomes smaller, the space of the second chamber 32 becomes smaller; The water cooling mechanism 23 is used to deliver circulating cooling water into the second chamber 32 to cool the sleeve 26 and further cool the composite current collector; When the cooling roller 2 is raised or lowered, the space size of the second chamber 32 is adaptively adjusted to facilitate the cooling water to flow through the heat-conducting surface, concentrate the water flow to cool the heat-conducting surface, and accelerate the cooling; the traditional tensioning and water cooling processes are combined to simplify the structure; the problem that the traditional spiral flow channel cools the entire traction shaft, cannot concentrate the cooling of the heat-conducting surface, has low cooling efficiency, and wastes water cooling resources is solved.

[0025] like Figure 6 , Figure 7 and Figure 8As shown, optionally, a fixing plate 4 is fixedly connected to the inner wall of the bottom end of the first chamber 31, and the fixing plate 4 divides the first chamber 31 into two symmetrical spaces. The outer sides of the two arc-shaped plates 6 are fitted and slid on the inner surface of the annular chamber 3 and are matched in size. A bending spring 5 is fastened between the bottom end of the arc-shaped plate 6 and the corresponding side surface of the fixing plate 4. The bending spring 5 is retractable along the arc trajectory of the first chamber 31. An oil delivery hole 7 is opened inside the fixing plate 4, and a plurality of evenly distributed oil holes 8 are symmetrically opened on the two inner side walls of the oil delivery hole 7 along the axial direction, and the oil holes 8 are connected to the first chamber 31.

[0026] In this embodiment, the first chamber 31 is filled with hydraulic oil, and the external hydraulic oil is input into the oil delivery hole 7, and then the hydraulic oil enters the corresponding first chamber 31 through the oil holes 8 on both sides. The increase of hydraulic oil in the first chambers 31 on both sides will push the upper ends of the arc plates 6 on both sides to rotate synchronously towards each other. At this time, the space in the second chamber 32 becomes smaller, and the bending springs 5 ​​on both sides are stretched; if the hydraulic oil in the first chambers 31 on both sides flows into the oil delivery hole 7 through the oil holes 8 and is discharged outward, the hydraulic oil in the first chamber 31 is reduced, and at the same time, the bending springs 5 ​​on both sides restore their deformation to pull the arc plates 6, so that the upper ends of the arc plates 6 on both sides rotate synchronously away from each other, and at this time, the space in the second chamber 32 becomes larger.

[0027] like Figure 2 , Figure 3 and Figure 7 As shown, optionally, the regulating mechanism includes an oil pipe 9, a solenoid valve 10, a sleeve 11, a piston plate 12 and a connecting rod 13. The oil pipe 9 is fixedly connected to the end of the oil delivery hole 7, the solenoid valve 10 is fixedly installed on the oil pipe 9, the end of the oil pipe 9 away from the oil delivery hole 7 is fixedly connected to the middle of the upper end of the sleeve 11, the outer side of the piston plate 12 is slidably connected to the inner side of the sleeve 11, the upper end of the connecting rod 13 is fixedly connected to the middle of the bottom end of the piston plate 12, and the upper end space of the piston plate 12 and the oil pipe 9 are filled with hydraulic oil.

[0028] In this embodiment, the piston plate 12 is pushed upward by the connecting rod 13, and the hydraulic oil in the upper space of the piston plate 12 moves upward and squeezes the hydraulic oil in the oil pipe 9 into the oil delivery hole 7; when the connecting rod 13 drives the piston plate 12 to move downward, the space at the upper end of the piston plate 12 becomes larger, and negative pressure is generated inside, and then the hydraulic oil in the oil delivery hole 7 is drawn out through the oil pipe 9 to fill the enlarged space at the upper end of the piston plate 12. The solenoid valve 10 realizes the on-off of the oil pipe 9.

[0029] like Figure 3 As shown, optionally, the bottom end of the sleeve 11 is open, and the space at the lower end of the piston plate 12 is connected to the external atmospheric pressure.

[0030] In this embodiment, the space at the lower end of the piston plate 12 is connected to the atmospheric pressure, which can ensure that the piston plate 12 will not be hindered when it is raised and lowered in the sleeve 11, thereby ensuring the normal oil pushing and pumping process.

[0031] like Figure 1 , Figure 3 and Figure 7 As shown, optionally, the lifting mechanism includes a base 1, a lifting plate 14, a fixed shaft 15, a connecting block 16, a bidirectional threaded screw 17, a servo motor 18, a guide rod 19 and a limit plate 20. The cooling roller 2 is fixedly installed inside the middle of the outer periphery of the fixed shaft 15, and the connecting blocks 16 are symmetrically fixedly connected at both ends of the fixed shaft 15. The bottom end of the guide rod 19 is fixedly connected to the upper end surface of the base 1, and the outer side of the guide rod 19 is slidably connected to the inside of the corresponding connecting block 16. The servo motor 18 is fixedly installed on the upper end surface of the base 1 and the output end is fixedly connected to the bottom end of the bidirectional threaded screw 17. The upper surface of the end of the lifting plate 14 is fixedly connected to the bottom end of the connecting rod 13, the bidirectional threaded screw 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 outer side of the bidirectional threaded screw 17, and the lifting plate 14 and the corresponding connecting block 16 are respectively located at the lower end and upper end of the bidirectional threaded screw 17.

[0032] In this embodiment, the servo motor 18 starts and drives the bidirectional threaded screw 17 to rotate, driving the lifting plate 14 and the connecting block 16 to move synchronously toward or away from each other in the vertical direction, thereby achieving: when the connecting block 16 drives the cooling roller 2 to rise, the lifting plate 14 moves downward, driving the piston plate 12 to move downward to pump oil, 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, driving the piston plate 12 to move upward to transport oil, and the space of the second chamber 32 becomes smaller.

[0033] like Figure 1 As shown, optionally, the upper ends of the bidirectional threaded screw 17 and the guide rod 19 are both fixedly connected to the limit plate 20 .

[0034] In this embodiment, by providing a limit plate 20 on the upper end of the bidirectional threaded screw 17 and the guide rod 19, it is ensured that the connecting block 16 does not slip when being lifted or lowered.

[0035] like Figure 1 , Figure 4 and Figure 5 As shown, optionally, annular grooves 24 are symmetrically provided on both sides of the outer surface of the cooling roller 2, bearings 25 are fixedly installed in the annular grooves 24, and both sides of the inner surface of the sleeve 26 are fixedly installed on the outer ring of the bearing 25, and the inner surface of the sleeve 26 rotates in contact with the outer surface of the cooling roller 2.

[0036] In this embodiment, the bearing 25 is provided to ensure that the sleeve 26 can rotate on the outer surface of the cooling roller 2, so that the composite current collector can be fitted and tensioned and transmitted on the upper surface of the sleeve 26. Here, the sleeve 26 is fitted with the cooling roller 2, which also makes it easier 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.

[0037] like Figure 1 and Figure 7 As shown, optionally, the water cooling mechanism 23 includes a water inlet pipe 21, a water outlet pipe 22 and a small water chiller. The side walls at both ends of the second chamber 32 are fixedly connected with the water inlet pipe 21 and the water outlet pipe 22, and the water inlet and outlet of the small water chiller are fixedly connected with the water inlet end of the water inlet pipe 21 and the water outlet end of the water outlet pipe 22.

[0038] In this embodiment, the small chiller transports cooling water to the second chamber 32 through the water inlet pipe 21 to cool the composite collector. The water that takes away the heat enters the machine through the water outlet pipe 22 for cooling, and then is put into use again to realize cold water circulation. Since this is existing technology, it will not be further described in this article.

[0039] like Figure 1 As shown, optionally, side plates 27 are symmetrically fixedly connected to both sides of the base 1, and bolts 28 are connected to the inner threads of the side plates 27.

[0040] In this embodiment, the base 1 is fixedly mounted on the mounting surface by rotating and tightening the bolts 28 in the side plates 27 to improve stability.

[0041] like Figure 1-8 As shown, a composite current collector processing method is based on the composite current collector traction device as above, and the steps are: S1: The traction shaft tractions and transports the composite current collector, and the composite current collector passes through the upper surface of the sleeve 26 sleeved on the cooling roller 2 for cooling; S2: When the composite current collector needs to be tensioned, the servo motor 18 starts and drives the bidirectional threaded screw 17 to rotate, driving the lifting plate 14 and the connecting block 16 to move synchronously in the vertical direction, the cooling roller 2 rises and the lifting plate 14 moves downward, driving the piston plate 12 to move downward to pump oil from the first chamber 31, and the space of the second chamber 32 becomes larger. At this time, the angle between the composite current collector and the upper surface of the sleeve 26 becomes larger, and the water cooling mechanism 23 transports cooling water into the second chamber 32, and the concentrated water flow cools the enlarged fitting surface; S3: When the composite current collector is over-tensioned, the servo motor 18 starts and drives the bidirectional threaded screw 17 to rotate in the opposite direction, driving the lifting plate 14 and the connecting block 16 to move synchronously in the vertical direction, the cooling roller 2 descends and the lifting plate 14 moves upward, driving the piston plate 12 to move upward to supply oil to the first chamber 31, and the space of the second chamber 32 becomes smaller. At this time, the angle between the composite current collector and the upper surface of the sleeve 26 becomes smaller, and the water cooling mechanism 23 transports cooling water into the second chamber 32, and the concentrated water flow cools the smaller fitting surface; S4: The composite current collector after cooling is rolled up on a winding roller, and the work is completed.

[0042] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.

Then, the water cooling mechanism (23) is used to transport 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 descend vertically, and the composite current collector is relieved of excessive tension by adjusting the height of the cooling roller (2). The lifting mechanism is started and the adjustment mechanism is triggered at the same time. The adjustment mechanism is started to fill the first chamber (31) with hydraulic oil, thereby driving the two arc plates (6) to rotate synchronously in opposite directions, and adjusting the space of the second chamber (32) to become smaller. At this time, the angle of contact between the composite current collector and the upper surface of the cooling roller (2) 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), thereby cooling the composite current collector; S4: The composite current collector after cooling is rolled up on a winding roller, and the work is completed.
