Description

Technical Field

[0001] This utility model belongs to the field of composite current collector technology, specifically relating to a composite current collector traction device. Background Technology

[0002] A current collector, as the name suggests, refers to a structure or component that collects current. In lithium-ion batteries, it mainly refers to metal foil, such as copper foil or aluminum foil. More broadly, it can also include the tabs. Their main function is to collect the current generated by the battery's active materials to form a larger current output. Therefore, the current collector should have sufficient contact with the active materials, and its internal resistance should be as low as possible.

[0003] Currently, the thickness of composite current collectors is usually less than 10μm. Due to their thinness and high molecular weight, they are prone to damage, wrinkles, and film breaks during the winding process. Therefore, a traction device is required. However, traditional traction devices have a single structural function and poor stability during traction, which cannot effectively traction the composite current collector, thus affecting the traction effect. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a composite current collector traction device, which solves the problems of single structure and function, poor stability during traction, and inability to effectively traction the composite current collector, thus affecting the traction effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite current collector traction device, comprising a support frame, a motor disposed on one side of the support frame, the output end of the motor being connected to a rotating shaft, a support bracket disposed on the top of the support frame, a threaded slide rod disposed on the bottom of the support bracket, a threaded disc threadedly connected to the surface of the threaded slide rod, a spring disposed on the bottom of the threaded disc, a slider disposed on one end of the spring, and the slider sliding on the surface of the threaded slide rod, a connecting shaft disposed on one side of the slider, traction rubber rollers disposed on the surfaces of both the connecting shaft and the rotating shaft, and a guide shaft disposed at the other end inside the support frame, the guide shaft being located on one side of the rotating shaft.

[0008] Preferably, a connecting plate is provided at one end of the interior of the support frame, and a triangular scraper is provided on one side of the connecting plate.

[0009] Preferably, the inner wall of the support frame is provided with limit support blocks, and the connecting plate is located on the top of the limit support blocks. The two sides of the support frame are respectively provided with second bolts, and one end of the second bolt passes through the support frame and is threadedly connected to the connecting plate.

[0011] Preferably, a fixing block is provided at each end of the support frame, and a fixing hole is provided on one side of the fixing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] During use, the motor, rotating shaft, and traction rubber roller work together to pull the composite data collector, ensuring stable traction. Springs, sliders, threaded rods, connecting shafts, and traction rubber rollers further enhance the traction effect, preventing the composite data collector from slipping on the traction rubber roller surface, which would affect the traction efficiency. Simultaneously, a fan, air duct, connecting box, connecting pipe, and air outlet work together to blow air onto the composite data collector, creating airflow and dispersing dust to prevent surface dust accumulation that could affect future performance. A triangular scraper is also included to flatten the composite data collector, preventing wrinkles that could compromise the traction effect. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 The present invention provides the following technical solution: a composite current collector traction device, including a support frame 1, a motor 19 is provided on one side of the support frame 1, the output end of the motor 19 is connected to a rotating shaft 4, a support frame 6 is provided on the top of the support frame 1, a threaded slide rod 20 is provided at the bottom of the support frame 6, a threaded disc 21 is threadedly connected to the surface of the threaded slide rod 20, a spring 13 is provided at the bottom of the threaded disc 21, a slider 14 is connected to one end of the spring 13, and the slider 14 slides on the surface of the threaded slide rod 20, a connecting shaft 7 is provided on one side of the slider 14, traction rubber rollers 2 are provided on the surfaces of both the connecting shaft 7 and the rotating shaft 4, and a guide shaft 3 is provided at the other end inside the support frame 1, and the guide shaft 3 is located on one side of the rotating shaft 4.

[0021] In this embodiment: By setting a limiting support block 23, the connecting plate 24 is restricted, limiting the fixed position of the connecting plate 24, and the second bolt 12 is set to connect and fix the connecting plate 24, thereby increasing the convenience of its installation, avoiding the need for later maintenance, increasing the convenience of disassembly, and improving the use effect.

[0022] In this embodiment: by setting a threaded disc 21, the threaded disc 21 is threadedly connected to the threaded slide bar 20, thereby allowing the threaded disc 21 to move on the surface of the threaded slide bar 20 to adjust the spring 13, increasing the downward force of the spring 13, which in turn causes the slider 14 to press down, thereby causing the connecting shaft 7 and the traction rubber roller 2 to press down, thus adjusting the clamping force between the traction rubber rollers 2, thereby increasing the effectiveness of use.

[0023] In this embodiment: by setting the first bolt 5, the first bolt 5 is fixed to the support frame 6, thereby increasing the installation effect, making it easier to disassemble and maintain later, and increasing the convenience of installation.

[0024] In this embodiment, by setting three sets of auxiliary roller shaft groups 10 and bearings 11, the auxiliary roller shaft groups 10 can move through the bearings 11, which can ensure flexible rotation and traction effect. Furthermore, setting three sets increases its stability.

[0025] The working principle and usage process of this utility model are as follows: After installation, during use, the composite current collector passes between the three sets of auxiliary roller shafts 10, then through the interior of the triangular scraper 22, through the connecting box 9, and finally between the traction rubber rollers 2. The motor 19 is activated, causing it to rotate via the rotating shaft 4, thus tractioning the composite current collector. The two sets of traction rubber rollers 2 provide more stable traction. Simultaneously, the spring force of the spring 13 causes the slider 14 to slide on the surface of the threaded slide bar 20, thereby causing the slider 14, connecting shaft 7, and traction rubber rollers 2 to move downwards, causing the upper traction rubber roller 2... The lower traction rubber roller 2 is pressed to increase the traction effect on the composite current collector and prevent the composite current collector from sliding on the surface of the traction rubber roller 2, which would affect the traction effect. At the same time, the fan 17 is turned on to deliver air through the air duct 8 to the interior of the connecting box 9. Through the connection between the connecting pipes 25, the air enters the interior of the connecting box 9 and is finally sprayed out from the air outlet 18, so that the air blows towards the composite current collector, drives the air flow, blows away the dust, and prevents dust from settling on the surface, which would affect the later use effect. A triangular scraper 22 is set to flatten the composite current collector and prevent wrinkles, which would affect the traction effect. All electrical equipment in this device is powered by an external power source.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
