Description

Technical Field

[0001] This utility model relates to the field of lithium battery copper foil production technology, specifically to an O-ring tension adjustment device. Background Technology

[0002] In the production of lithium-ion battery copper foil, the foil production process is one of the key steps. The foil production machine drives the O-rings to rotate continuously through a traction device. During this process, the O-rings can seal the titanium rollers, preventing leakage of electrolytes and other substances, maintaining the stability of the environment around the titanium rollers, and thus ensuring the smooth progress of the foil production process.

[0003] During the operation of the foil forming machine, the force on the O-ring varies due to various factors (such as traction speed and the surface roughness of the titanium roller). When the force on the O-ring is too great, it will deform excessively, leading to a decrease in sealing effect, leakage from the grooves of the titanium roller, and consequently, copper plating problems at the edges. Conversely, when the force is too small, the O-ring is prone to loosening and shaking during operation, and may even detach from the guide roller, causing the titanium roller to tear at the edges and affecting the quality of the copper foil. Utility Model Content

[0004] The purpose of this invention is to provide an O-ring tension adjustment device. This O-ring tension adjustment device adjusts the tension of the O-ring by adjusting the height of the moving roller on the fixed frame, thereby ensuring the seal of the O-ring on the titanium roller and ensuring the quality of the copper foil.

[0007] In some embodiments, the adjustment assembly further includes two auxiliary slots, which are symmetrically arranged at both ends of the lifting slot; Two sliding screws are provided, which are slidably disposed in the auxiliary groove and are connected to the moving roller through the auxiliary groove.

[0008] In some embodiments, the adjustment assembly further includes a connecting plate disposed on the side of the movable roller near the fixed frame, and connected to both the sliding screw and the lifting block.

[0009] In some embodiments, the adjusting assembly further includes a limiting washer, which is sleeved on the sliding screw, and the outer diameter of the limiting washer is greater than the width of the auxiliary groove.

[0010] In some embodiments, a cleaning component is also included, which is disposed on the side of the fixing frame near the first fixed roller, and the cleaning component can clean the O-ring.

This allows for real-time adjustment of the O-ring tension based on the actual operating conditions of the foil-making machine and the stress state of the O-ring, preventing problems such as deformation, loosening, and vibration caused by excessive or insufficient stress. Maintaining appropriate O-ring tension at all times improves the sealing effect of the O-ring on the titanium roller, reduces leakage from the titanium roller grooves, avoids copper plating issues at the edges, and ensures the production quality of the copper foil.

[0014] This invention uses a dropper to evenly drip cleaning water onto the surface of the O-ring, which can dilute and promptly rinse away the copper sulfate solution on the surface of the O-ring, preventing it from precipitating and crystallizing and adhering to the O-ring and roller. This avoids the problems of operation jamming and reduced sealing effect caused by the accumulation of crystals, and reduces the risk of O-ring jamming or falling off. Attached Figure Description

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] refer to Figure 1-2An O-ring tensioning adjustment device includes a fixed frame 1, a first fixed roller 2, a second fixed roller 3, a movable roller 4, an adjustment assembly 5, and a cleaning assembly 6. The fixed frame 1 is the supporting structure of the entire device, including a fixed plate 11 and a support plate 12. The fixed plate 11 can be fixed to the work platform by bolt assembly. The support plate 12 is vertically fixed to the fixed plate 11. The support plate 12 has a rotatable first fixed roller 2, a second fixed roller 3, and a movable roller 4 on one side, which can be fixed by bolt assembly. This is prior art and will not be described in detail here. The movable roller 4 is located between the first fixed roller 2 and the second fixed roller. Between the first fixed roller 2, the second fixed roller 3, and the moving roller 4, an O-ring drive connection is formed (this is existing technology and will not be described in detail here), forming a closed-loop structure to ensure that the O-ring can maintain a stable tension during operation. On the other side of the support plate 12, an adjustment component 5 is provided. The adjustment component 5 is located between the moving roller 4 and the fixed frame 1. The adjustment component 5 can adjust the height of the moving roller 4 on the fixed frame 1, thereby changing the tension of the O-ring between the first fixed roller 2, the second fixed roller 3, and the moving roller 4, thus ensuring the seal of the O-ring on the titanium roller and ensuring the quality of the copper foil.

[0019] In some embodiments, the adjusting assembly 5 includes a first fixing block 51, a second fixing block 52, a lead screw 53, a lifting groove 54, and a lifting block 55. The first fixing block 51 is located at the bottom of the other side of the support plate 12, and the second fixing block 52 is located at the top of the other side of the support plate 12. The first fixing block 51, the second fixing block 52, and the support plate 12 can all be welded and fixed. The lead screw 53 is rotatably disposed between the first fixing block 51 and the second fixing block 52, and the top of the lead screw 53 passes through the second fixing block 52, facilitating subsequent connection of a drive device such as a handwheel (see reference). Figure 2 (A motor can also be configured according to actual needs) to achieve precise control of the rotation of the lead screw 53. A lifting groove 54 is provided vertically on the support plate 12. The lifting groove 54 provides a precise guide track for the lifting block 55, ensuring that the lifting block 55 always maintains a vertical movement trajectory during the lifting process, avoiding deviation or shaking, thereby ensuring the accuracy of the position adjustment of the moving roller 4. The lifting block 55 is sleeved on the lead screw 53 and screwed to the lead screw 53. The lifting block 55 passes through the lifting groove 54 and connects to the moving roller 4. The lifting block 55 can rise and fall within the lifting groove 54. When the lead screw 53 rotates under the action of external driving force, according to the transmission principle of the lead screw and nut pair, the lifting block 55 will move linearly along the axis of the lead screw 53. With the lifting block 55 rising and falling, the moving roller 4 will also move up and down synchronously, thereby realizing the adjustment of the height of the moving roller 4 on the fixed frame 1.

[0020] In some embodiments, to further improve the stability and reliability of the position adjustment of the movable roller 4, the adjustment assembly 5 also includes two auxiliary grooves 56 and two sliding screws 57. The two auxiliary grooves 56 are symmetrically arranged at both ends of the lifting groove 54 and are arranged vertically. Together with the lifting groove 54, the auxiliary grooves 56 form a guiding system for the position adjustment of the movable roller 4, providing a precise track for the sliding screws 57 to slide, ensuring that the movable roller 4 maintains a stable movement trajectory during the adjustment process. The sliding screws 57 are slidably disposed in the auxiliary grooves 56 and pass through the auxiliary grooves 56 to connect with the movable roller 4. When the lifting block 55 moves up and down under the drive of the lead screw 53, the sliding screws 57 slide synchronously in the auxiliary grooves 56. The auxiliary lifting blocks 55 share the weight of the movable roller 4, dispersing the stress generated during the adjustment process, thereby avoiding problems such as wear, deformation, or movement jamming of the lifting blocks 55 due to uneven force, and improving the service life and adjustment accuracy of the adjustment assembly.

[0021] In some embodiments, the adjustment assembly 5 further includes a connecting plate 58, which is located on the side of the movable roller 4 near the fixed frame 1 and is connected to both the sliding screw 57 and the lifting block 55. The connecting plate 58 enables the fixed connection between the sliding screw 57 and the lifting block 55, further enhancing the stability and rigidity of the movable roller 4 during the adjustment process and ensuring that the movable roller 4 can maintain precise position adjustment under complex working conditions.

[0022] In some embodiments, the adjusting assembly 5 further includes a limiting washer 59, which is sleeved on the sliding screw 57, and the outer diameter of the limiting washer 59 is larger than the width of the auxiliary groove 56. When the sliding screw 57 slides in the auxiliary groove 56, the limiting washer 59 can prevent the sliding screw 57 from dislodging from the auxiliary groove 56 due to excessive movement, thereby avoiding equipment failure or safety accidents caused by component detachment and improving the safety and reliability of the adjusting assembly.

[0023] In some embodiments, during the operation of the foil-making machine, O-rings carry copper sulfate solution out of the electrolytic cell. When this solution comes into contact with the external environment, due to temperature changes, the high-concentration copper sulfate solution will precipitate a large amount of crystals. These crystals gradually adhere to the surfaces of the O-rings and rollers. Over time, the accumulation of crystals increases the friction between the O-rings and rollers, causing operational jamming. In severe cases, the accumulation of crystals can disrupt the normal fit between the O-rings and rollers, causing the O-rings to detach from the rollers, further affecting the sealing effect and exacerbating the copper plating problem on the edges of the titanium rollers.

[0024] To address the issues of decreased sealing performance of O-rings due to copper sulfate crystals adhering to them during equipment operation, a cleaning component 6 is added to the side of the fixed frame 1 near the first fixed roller 2. The cleaning component 6 can clean the O-rings and prevent copper sulfate crystals from adhering to them.

[0025] Specifically, the cleaning component 6 includes an inlet pipe 61, a delivery pipe 62, and three drip tubes 63. The inlet pipe 61 connects to an external water source (including a water storage tank, a water pump, etc., which are existing technologies and will not be described in detail here), providing a stable and continuous supply of cleaning water to the cleaning component 6, ensuring that the cleaning component 6 can continuously perform its cleaning function during equipment operation. The delivery pipe 62 is fixed to the support plate 12 and can be firmly installed on the support plate 12 by welding, snap-fit, or other fixing methods, and is tightly connected to the inlet pipe 61, forming a water delivery channel to ensure that the cleaning water can be efficiently and leak-free delivered to the drip tubes 63. The three drip tubes 63 are respectively located above the first fixed roller 2, the second fixed roller 3, and the moving roller 4, with the outlet of the drip tube 63 precisely aligned with the location of the O-ring. The frequency of water droplets falling from the drip tube 63 can be adjusted according to actual needs. The specific structure of the drip tube 63 is existing technology and will not be described in detail here. When the equipment is running, cleaning water is delivered to the dripper 63 through the inlet pipe 61 and the delivery pipe 62. The dripper 63 then drips the water evenly and slowly onto the surface of the O-ring, providing continuous and gentle cleaning. This effectively dissolves and washes away the copper sulfate crystals adhering to the surface of the O-ring, preventing the adhesion of copper sulfate crystals, ensuring the sealing performance of the O-ring, reducing the equipment failure rate, and extending the service life of the equipment.

[0026] The specific working principle is as follows: When it is necessary to adjust the tension of the O-ring, rotate the lead screw 53. Since the lifting block 55 is screwed to the lead screw 53 and is constrained by the lifting groove 54, the lifting block 55 will move vertically up and down along the lifting groove 54 under the drive of the lead screw 53. The movement of the lifting block 55 will cause the moving roller 4 to move up and down, thereby changing the wrap angle and tension of the O-ring between the first fixed roller 2, the second fixed roller 3, and the moving roller 4, achieving precise adjustment of the O-ring tension so that it can maintain a suitable tightness according to actual production needs. Simultaneously, the sliding screw 57 slides within the auxiliary groove 56, providing auxiliary support and guiding for the moving roller 4, ensuring the stability and accuracy of the adjustment process.

[0027] During the operation of the foil-making machine, the O-rings continuously carry copper sulfate solution out of the electrolytic cell. When the portion of the O-ring carrying the copper sulfate solution moves to the first fixed roller 2, the second fixed roller 3, and the moving roller 4, the dropper 63 of the cleaning component 6 continuously drips cleaning water onto the surface of the O-ring. The cleaning water dilutes and washes away the copper sulfate solution and crystals adhering to the surface of the O-ring, preventing the accumulation of copper sulfate crystals on the surface of the O-ring and rollers, thereby preventing the precipitation of copper sulfate crystals.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
