Description

Technical Field

[0001] This invention relates to the field of electrode foil production technology, specifically to an electrode foil production conveying tension adjustment mechanism. Background Technology

[0002] Electrode foil is a core material for aluminum electrolytic capacitors. Its production process is a continuous precision manufacturing process, mainly including multiple continuous processes such as etching, formation, cleaning, drying, and winding. Stable transport of electrode foil between each process is a prerequisite for ensuring product quality. Due to the characteristics of electrode foil itself, such as thinness, brittleness, and the formation of a porous corrosion layer and dense oxide film on the surface, the stability, uniformity, and adjustment accuracy of tension are extremely important during transport. Abnormal fluctuations in tension will directly damage the surface functional layer of the electrode foil, leading to deterioration of the product's electrical performance, exceeding dimensional accuracy standards, and even causing the foil to tear and be scrapped, seriously affecting production efficiency and yield.

[0003] Currently, in electrode foil production conveyor lines, tension adjustment mechanisms mostly adopt simple and low-cost spring-type tensioning structures. This type of structure usually sets a tension roller in the middle section of the electrode foil conveying, connects the tension roller to the spring assembly, and relies on the elastic force generated by the elastic deformation of the spring to act on the tension roller. By adjusting the preload of the spring, the pressure of the tension roller on the electrode foil is changed, thereby realizing the adjustment of tension. However, when the tension of the electrode foil is adjusted by the elastic force of the spring, the spring will generate self-excited vibration and resonance due to the external force. The vibration will be transmitted to the foil, resulting in large fluctuations in the foil conveying and affecting the stability of the foil conveying. Therefore, an electrode foil production conveying tension adjustment mechanism is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an electrode foil production and conveying tension adjustment mechanism to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electrode foil production conveying tension adjustment mechanism, comprising: The base plate has two side plates that are symmetrically arranged on the top outer surface, and two guide rollers are rotatably arranged between the two side plates. A tensioning assembly is located between two side plates and is used to tension the electrode foil. An adjustment component is located at the tensioning component, and the tension of the electrode foil is autonomously adjusted by the adjustment component.

[0006] As a further explanation of the present invention, the tensioning assembly includes two support blocks, and the outer surfaces of the two side plates are provided with receiving grooves. The two support blocks are respectively accommodated inside the two receiving grooves, and a tensioning roller is rotatably arranged between the two support blocks.

[0007] As a further explanation of the present invention, the adjusting component includes a fixed cylinder, the support block has a fixed groove inside, the fixed cylinder is disposed inside the fixed groove, a cylindrical airbag is installed inside the fixed cylinder, a piston cylinder is connected to the top outer surface of the fixed cylinder, a first piston disc is movably inserted inside the piston cylinder, and a piston rod is fixedly connected to the top outer surface of the first piston disc.

[0008] As a further explanation of the present invention, a detection component is provided on one side of the fixed cylinder, and the sealing performance of the cylindrical airbag is detected by the detection component.

[0009] As a further explanation of the present invention, the detection component includes a connecting pipe connected to one side of the fixed cylinder, the other end of the connecting pipe being connected to an extension pipe, the extension pipe extending to one side of the support block, and a second piston disc slidably connected to the inner surface of the extension pipe.

[0010] As a further explanation of the present invention, a connecting rod is fixedly connected to the other end of the second piston disc, and a compression disc is fixedly connected to the other end of the connecting rod. A connecting tube is provided on the bottom outer surface of the extension tube, and a fixing rod is movably inserted into the top outer surface of the connecting tube. A triangular block is fixedly connected to the top of the fixing rod, and a rubber piston is fixedly connected to the bottom of the fixing rod. The rubber piston is slidably connected to the inside of the connecting tube. A discharge tube is connected to the bottom outer surface of the connecting tube, and a spring-loaded one-way valve is installed inside the discharge tube. An injection tube is connected to the outer surface of the connecting tube, and a sealing cap is threadedly connected to the outer surface of the injection tube.

[0011] As a further explanation of the present invention, a first spring is provided between the inner wall of the extension tube and the second piston disc.

[0012] As a further explanation of the present invention, a second spring is fixedly connected between the triangular block and the inner wall of the extension tube, and the second spring is sleeved on the outside of the fixed rod.

[0013] As a further explanation of the present invention, the outer surface of the side plate is provided with an adjustment component, which adjusts the pretension force of the cylindrical airbag.

[0014] As a further explanation of the present invention, the adjustment assembly includes a mounting plate disposed above the side plate, wherein an adjustment screw is threaded through the outer surface of the mounting plate, and the other end of the adjustment screw is rotatably connected to a piston rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the electrode foil is supported by a tensioning roller, and the air pressure is delivered to the interior of the cylindrical airbag by the sliding of the first piston disc inside the piston cylinder. The tension of the electrode foil is autonomously adjusted by the expansion of the cylindrical airbag. The deformation of the cylindrical airbag replaces the deformation of the spring, thus avoiding the spring from vibrating continuously due to external force, which would affect the stability of the electrode foil delivery.

[0016] 2. In this invention, the air pressure during the expansion of the cylindrical airbag is transmitted to the second piston disc. The air pressure overcomes the elastic force of the second spring, causing the second piston disc to move the connecting rod and the extrusion disc. When the sealing of the cylindrical airbag is poor, the elastic force of the second spring causes the extrusion disc to reset, causing the extrusion disc to squeeze the triangular block. The triangular block then drives the fixing rod, causing the rubber piston to increase the air pressure inside the connecting tube, squeezing out the red ink from the discharge tube. This allows for timely judgment of whether the sealing of the cylindrical airbag is in good condition.

[0017] 3. In this invention, when it is necessary to adjust the expansion preload of the cylindrical airbag, the adjustment screw is rotated, which drives the piston rod to move downward, thereby adjusting the expansion force of the cylindrical airbag. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to the following: Figures 1-7 This invention provides a technical solution: an electrode foil production and conveying tension adjustment mechanism, comprising a base plate 100, a tensioning assembly, and an adjustment assembly. Two side plates 101 arranged symmetrically are fixedly connected to the top outer surface of the base plate 100. Two guide rollers 102 are rotatably arranged between the two side plates 101. The tensioning assembly is located between the two side plates 101 and tensions the electrode foil accordingly. The adjustment assembly is located at the tensioning assembly and autonomously adjusts the tension of the electrode foil. Specifically, the electrode foil production and conveying tension adjustment mechanism includes a base plate 100, a tensioning assembly, and an adjustment assembly. The base plate 100 is made of high-strength alloy material, possessing good load-bearing capacity and structural stability, effectively preventing deformation during long-term operation. Two symmetrically arranged side plates 101 are fixedly connected to the top outer surface of the base plate 100 by bolts. The two side plates 101 are arranged parallel to each other and perpendicular to the base plate 100, ensuring the overall structural regularity and balanced stress distribution. Two guide rollers 102 are rotatably arranged between the two side plates 101. The two ends of the guide rollers 102 are rotatably connected to the side plates 101 through bearings. The bearings can effectively reduce the friction during the rotation of the guide rollers 102, reduce the wear during the electrode foil conveying, and ensure the smooth rotation of the guide rollers 102, thereby ensuring the stability of the electrode foil conveying process. The tensioning assembly is located between the two side plates 101 and on one side of the two guide rollers 102. The tensioning assembly provides stable tension for the electrode foil, providing a basis for tension adjustment. The adjustment assembly is integrated at the tensioning assembly and works in conjunction with it. The adjustment assembly can autonomously adapt and adjust the tension of the electrode foil, responding in real time to changes in tension during the electrode foil conveying process, ensuring that the tension is always maintained within a reasonable range.

[0022] In this embodiment, the tensioning assembly includes two support blocks 200. The outer surfaces of the two side plates 101 are provided with receiving grooves. The two support blocks 200 are respectively housed inside the two receiving grooves. A tensioning roller 201 is rotatably arranged between the two support blocks 200. Specifically, the tensioning assembly includes two support blocks 200 with identical structures. The opposite outer surfaces of the two side plates 101 are provided with receiving grooves that are adapted to the support blocks 200. The receiving grooves are arranged vertically and their inner walls are polished to ensure the smoothness of the support blocks 200 when moving inside the receiving grooves, while avoiding excessive friction between the support blocks 200 and the inner walls of the receiving grooves, which would affect the adjustment sensitivity. Two support blocks 200 are respectively adapted to be accommodated inside two receiving grooves, and the support blocks 200 can slide freely along the vertical direction of the receiving grooves. A tensioning roller 201 is rotatably arranged between the two support blocks 200 through a bearing. The tensioning roller 201 is arranged parallel to the guide roller 102, and a wear-resistant rubber sleeve is sleeved on the outer surface of the tensioning roller 201. The surface of the rubber sleeve is provided with anti-slip texture, which can effectively increase the friction between the electrode foil and ensure the tensioning effect, and avoid scratching or damaging the surface of the electrode foil, thus ensuring the product quality of the electrode foil. The electrode foil is passed between the guide roller 102 and the tensioning roller 201, and the tensioning roller 201 is used to tighten the electrode foil and adjust the tension of the electrode foil.

[0023] In this embodiment, the adjustment component includes a fixed cylinder 300. The support block 200 has a fixed groove inside, and the fixed cylinder 300 is disposed inside the fixed groove. A cylindrical airbag 301 is installed inside the fixed cylinder 300. A piston cylinder 302 is connected to the top outer surface of the fixed cylinder 300. A first piston disc 303 is movably inserted inside the piston cylinder 302. A piston rod 304 is fixedly connected to the top outer surface of the first piston disc 303. Specifically, the cylindrical airbag 301 is made of high-strength elastic sealing material, which has good elastic deformation capability and sealing performance. It can absorb the fluctuation of tension force through its own elastic deformation and realize the autonomous adjustment of tension force. The piston cylinder 302 is vertically connected to the top outer surface of the fixed cylinder 300. The piston cylinder 302 is connected to the inside of the fixed cylinder 300, and a sealing gasket is provided at the connection between the two to ensure the sealing of the connection and prevent gas leakage. A first piston disc 303 adapted to the inner wall of the piston cylinder 302 is movably inserted inside the piston cylinder 302. A sealing ring is fitted on the outer surface of the first piston disc 303. The sealing ring fits tightly with the inner wall of the piston cylinder 302, further improving the sealing performance between the piston cylinder 302 and the first piston disc 303. A piston rod 304 is vertically fixedly connected to the top outer surface of the first piston disc 303. The top end of the piston rod 304 extends to the outside of the piston cylinder 302, and the piston rod 304 is connected to the top inner wall of the support block 200. During normal electrode foil transport, the cylindrical airbag 301 is in a state of expansion. Its elastic force pushes the fixed cylinder 300, which in turn drives the support block 200 and the tensioning roller 201 to maintain a stable tension, ensuring that the tension of the electrode foil is maintained within the set range. When the tension of the electrode foil increases at a certain moment due to fluctuations in transport speed or local pulling, the tension of the electrode foil will increase accordingly. At this time, the electrode foil exerts downward pressure on the tensioning roller 201. This pressure is transmitted to the tensioning roller 201, causing the tensioning roller 201 to move downward under force. The tensioning roller 201 drives the support blocks 200 on both sides to slide downward along the receiving groove. During the movement of the support blocks 200, the piston rod 304 moves downward synchronously, causing relative movement between the piston cylinder 302 and the piston rod 304, which in turn pushes the first piston disc 303 to slide downward inside the piston cylinder 302. When the first piston disc 303 slides downward, it compresses the gas inside the fixed cylinder 300, causing the cylindrical airbag 301 to undergo compression deformation under gas pressure. The elastic deformation of the cylindrical airbag 301 absorbs the increase in tension force, thus achieving autonomous buffering and adjustment of the electrode foil tension. Conversely, when the pulling force of the electrode foil decreases, the tension force decreases accordingly. The cylindrical airbag 301, under its own elastic restoring force, expands again, pushing the first piston disc 303 upward, causing the piston rod 304 and support block 200 to move upward, and the tensioning roller 201 to move upward synchronously, increasing the tension on the electrode foil and ensuring that the tension force is always maintained within a reasonable range. Compared with the traditional spring adjustment structure, this embodiment uses the deformation of the cylindrical airbag 301 instead of the spring deformation, effectively avoiding the problem of continuous autonomous vibration of the spring after being subjected to external force, reducing the impact of vibration on the stability of electrode foil conveying. At the same time, the deformation process of the cylindrical airbag 301 is smoother, the adjustment accuracy is higher, and it can better adapt to the conveying requirements of the electrode foil.

[0024] Example 2: Please refer to the following: Figures 1-7 The present invention provides a technical solution: a detection component is provided on one side of the fixed cylinder 300. The detection component detects the sealing performance of the cylindrical airbag 301. Specifically, the detection component can detect the sealing performance of the cylindrical airbag 301 in real time, promptly detect leakage problems of the cylindrical airbag 301, avoid tension adjustment failure due to sealing failure of the cylindrical airbag 301, thereby ensuring the continuity of electrode foil production and transportation, and reducing the production failure rate.

[0025] In this embodiment, the detection component includes a connecting pipe connected to one side of the fixed cylinder 300, and an extension pipe 400 connected to the other end of the connecting pipe. The extension pipe 400 extends to one side of the support block 200, and a second piston disc 401 is slidably connected to the inner surface of the extension pipe 400. Specifically, when the cylindrical airbag 301 is in a normal sealed state, the gas inside it remains stable, and some gas is transported to the extension pipe 400 through the connecting pipe. The air pressure inside the extension pipe 400 is maintained within a set range, and the air pressure continuously squeezes the second piston disc 401, causing it to overcome the elastic force of the first spring 407 and remain in a set position inside the extension pipe 400. When the cylindrical airbag 301 leaks, the air pressure inside it gradually decreases, and the air pressure inside the extension pipe 400 also decreases accordingly. At this time, the second piston disc 401 will move towards the connecting pipe under the action of the elastic restoring force of the first spring 407. The movement of the second piston disc 401 can directly reflect the sealing state of the cylindrical airbag 301.

[0026] In this embodiment, a connecting rod 402 is fixedly connected to the other end of the second piston disc 401, and a compression disc 403 is fixedly connected to the other end of the connecting rod 402. A connecting pipe 405 is provided on the bottom outer surface of the extension pipe 400, and a fixing rod is movably inserted into the top outer surface of the connecting pipe 405. A triangular block 404 is fixedly connected to the top of the fixing rod, and a rubber piston is fixedly connected to the bottom of the fixing rod. The rubber piston is slidably connected to the inside of the connecting pipe 405. A discharge pipe 406 is connected to the bottom outer surface of the connecting pipe 405, and a spring-loaded one-way valve is installed inside the discharge pipe 406. An injection pipe is connected to the outer surface of the connecting pipe 405. The outer surface of the injection tube is threaded with a sealing cap. A first spring 407 is provided between the inner wall of the extension tube 400 and the second piston disc 401. Specifically, the inclined surface of the triangular block 404 faces the extrusion disc 403, and the position of the triangular block 404 corresponds to the position of the extrusion disc 403, so that the extrusion disc 403 can accurately extrude the triangular block 404 when it moves. A rubber piston is fixedly connected to the bottom of the fixing rod. The rubber piston fits tightly with the inner wall of the connecting tube 405, and the rubber piston can slide along the vertical direction of the connecting tube 405. A sealing structure is provided between the rubber piston and the inner wall of the connecting tube 405 to ensure the sealing between the two. The bottom outer surface of the connecting pipe 405 is vertically connected to the discharge pipe 406. A spring-loaded one-way valve is installed inside the discharge pipe 406. The spring-loaded one-way valve is directed from the connecting pipe 405 to the discharge pipe 406 to prevent the discharged liquid from flowing back. One side of the outer surface of the connecting pipe 405 is connected to an injection pipe. The injection pipe is used to inject red ink for testing into the connecting pipe 405. A sealing cap is threaded onto the outer surface of the injection pipe. The sealing cap can seal the injection pipe to prevent ink leakage. When the cylindrical airbag 301 is in a good sealed state, the air pressure in the extension tube 400 is stable, the second piston disc 401 is held in the set position, and the connecting rod 402 and the extrusion disc 403 are also in a stationary state. At this time, the extrusion disc 403 does not contact the triangular block 404, and the triangular block 404 and the fixing rod remain stable under their own weight and the action of subsequent components. The rubber piston is located at the top of the connecting tube 405, and the red ink inside the connecting tube 405 is in a stationary state and will not be discharged from the discharge tube 406. When the cylindrical airbag 301 leaks due to poor sealing, the air pressure inside the extension tube 400 drops. Under the elastic restoring force of the first spring 407, the second piston disc 401 moves towards the connecting tube. The second piston disc 401 drives the connecting rod 402 to move synchronously. The connecting rod 402 drives the extrusion disc 403 to move towards the triangular block 404. As the extrusion disc 403 moves, it contacts the inclined surface of the triangular block 404 and generates a downward extrusion force. At this time, the triangular block 404 moves downward under the extrusion force, driving the fixing rod to move downward synchronously. The fixing rod drives the bottom rubber piston along the inner wall of the connecting tube 405. As the rubber piston slides downwards, it squeezes the red ink inside the connecting pipe 405, increasing the air pressure inside the connecting pipe 405. When the air pressure reaches the opening pressure of the spring-loaded check valve, the spring-loaded check valve opens, and the red ink inside the connecting pipe 405 is discharged from the discharge pipe 406 through the spring-loaded check valve. By observing whether red ink is discharged from the discharge pipe 406, the operator can promptly determine whether the sealing of the cylindrical airbag 301 is in good condition. Once ink is found to be discharged, the machine can be stopped immediately for inspection and replacement of the cylindrical airbag 301 to avoid tension adjustment failure due to sealing failure of the cylindrical airbag 301, thus ensuring smooth production.

[0027] In this embodiment, a second spring 408 is fixedly connected between the triangular block 404 and the inner wall of the extension tube 400. The second spring 408 is sleeved on the outside of the fixing rod. Specifically, the second spring 408 is fixedly connected between the triangular block 404 and the inner wall of the extension tube 400. The second spring 408 is sleeved on the outside of the fixing rod, and one end of the second spring 408 is fixedly connected to the bottom of the triangular block 404, and the other end is fixedly connected to the inner wall of the extension tube 400. The second spring 408 is always in a naturally stretched state, providing an upward restoring force for the triangular block 404. Specifically, when the extrusion disc 403 extrudes the triangular block 404, the triangular block 404 moves downward, causing the second spring 408 to be further stretched and undergo elastic deformation. When the sealing problem of the cylindrical airbag 301 is resolved and the air pressure in the extension tube 400 returns to normal, the extrusion disc 403 no longer applies extrusion force to the triangular block 404. At this time, the second spring 408 contracts under its own elastic restoring force, driving the triangular block 404 to return to its original position. The triangular block 404 drives the fixing rod and the rubber piston to return to their original positions simultaneously.

[0028] Example 3: Please refer to the following: Figures 1-7 The present invention provides a technical solution: the outer surface of the side plate 101 is provided with an adjustment component, and the pretension force of the cylindrical airbag 301 is adjusted by the adjustment component. Specifically, the pretension force of the cylindrical airbag 301 can be flexibly adjusted by the adjustment component, so as to accurately set the initial tension force of the electrode foil according to the production specifications and conveying requirements of the electrode foil.

[0029] In this embodiment, the adjustment assembly includes a mounting plate 500 disposed above the side plate 101. An adjusting screw 501 is threaded through the outer surface of the mounting plate 500. The other end of the adjusting screw 501 is rotatably connected to the piston rod 304. Specifically, when it is necessary to adjust the expansion preload of the cylindrical airbag 301 to set the initial tension of the electrode foil, the operator rotates the adjusting knob to drive the adjusting screw 501 to move up and down along the threaded hole of the mounting plate 500. When the adjusting screw 501 moves downward, it pushes the piston rod 304 to move downward simultaneously. The piston rod 304 pushes the first piston disc 303 downward to squeeze the gas inside the fixed cylinder 300, causing the cylindrical airbag to move downward. As the expansion of the cylindrical airbag 301 increases, its elastic force strengthens, which in turn drives the tensioning roller 201 to move upward, increasing the tension on the electrode foil and improving the initial tension. Conversely, when the adjustment knob is turned to move the adjustment screw 501 upward, the piston rod 304 moves upward under the elastic restoring force of the cylindrical airbag 301, reducing the expansion of the cylindrical airbag 301 and weakening the elastic force. The tensioning roller 201 then moves downward, reducing the tension on the electrode foil and lowering the initial tension, until the pre-tension of the cylindrical airbag 301 and the initial tension of the electrode foil are adjusted to the set requirements, adapting to the production of electrode foils of different specifications and with different conveying requirements.

[0030] Working principle: In use, the electrode foil is passed between the guide roller 102 and the tensioning roller 201. The tensioning roller 201 tightens the electrode foil and adjusts the tension of the electrode foil. When the tension of the electrode foil changes due to the increased tensile force at a certain moment, the force on the electrode foil is transmitted to the tensioning roller 201, causing the tensioning roller 201 to be stressed. The tensioning roller 201 drives the support block 200 to move, causing relative movement between the piston cylinder 302 and the piston rod 304. This causes the first piston disc 303 to move inside the piston cylinder 302, thereby deforming the cylindrical airbag 301. The deformation of the cylindrical airbag 301 replaces the deformation of the spring, thus autonomously adjusting the tension of the electrode foil and avoiding the continuous autonomous vibration of the spring under external force, which would affect the stability of the electrode foil conveying. When the cylindrical airbag 301 expands, the gas generated is delivered into the extension tube 400. The air pressure compresses the second piston disc 401, causing it to overcome the elastic force of the first spring 407 and move. When the cylindrical airbag 301 is not well sealed, the second piston disc 401 is not subjected to the compressive force of the air pressure. At this time, the elastic restoring force of the first spring 407 causes the second piston disc 401 to return to its original position. The second piston disc 401 drives the connecting rod 402 and the compression disc 403 to move, causing the compression disc 403 to compress the triangular block 404. At this time, the triangular block 404 moves downward, causing the rubber piston at one end of the fixed rod to move, increasing the air pressure inside the connecting tube 405. The air pressure enters the discharge tube 406, causing the red ink inside the connecting tube 405 to be discharged from the discharge tube 406 through the spring-loaded one-way valve, thereby timely determining whether the sealing of the cylindrical airbag 301 is in good condition. When it is necessary to adjust the expansion preload of the cylindrical airbag 301 to set the initial tension of the electrode foil, the operator rotates the adjustment knob to move the adjustment screw 501 up and down along the threaded hole of the mounting plate 500. When the adjustment screw 501 moves downward, it pushes the piston rod 304 downward simultaneously. The piston rod 304 pushes the first piston disc 303 downward to compress the gas inside the fixed cylinder 300, thereby increasing the expansion degree of the cylindrical airbag 301 and enhancing its elastic force. This, in turn, drives the tensioning roller 201 upward to increase the expansion preload. The tensioning force on the electrode foil is increased to improve the initial tension. Conversely, when the adjusting knob is turned to move the adjusting screw 501 upward, the piston rod 304 moves upward under the elastic restoring force of the cylindrical air bladder 301. The expansion degree of the cylindrical air bladder 301 decreases, the elastic force weakens, and the tensioning roller 201 moves downward, reducing the tensioning force on the electrode foil and lowering the initial tension until the pre-tensioning force of the cylindrical air bladder 301 and the initial tension of the electrode foil are adjusted to the set requirements, adapting to the production of electrode foils of different specifications and with different conveying requirements.
