Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic copper foil processing, and particularly relates to a self - pressing device for the squeezing roller of a copper foil forming machine. Background Technique

[0002] As a key link in the production of electrolytic copper foil, the process of copper foil forming includes multiple steps such as liquid supply, copper foil forming, water washing, liquid squeezing, and drying. After the copper foil forming process is completed, it is followed by squeezing and water washing through a squeezing roller, then squeezing water again using the squeezing roller, and finally drying.

[0003] Generally speaking, most of the surface defects of copper foil in the production process originate from the copper foil forming process. Especially during the process of squeezing water and liquid in the copper foil forming process, it is crucial to ensure that the squeezing roller closely adheres to the surface of the copper foil. Otherwise, it may lead to incomplete liquid squeezing or debonding of the roller surface, thus causing copper foil quality problems. In the prior art, the structure of the squeezing roller used for squeezing water and liquid on the outgoing foil end of the copper foil forming machine is too simple to realize the on - line adjustment of the fitting degree between the squeezing roller and the copper foil. Summary of the Utility Model

[0004] The technical problem solved by the utility model is to provide a self - pressing device for the squeezing roller of a copper foil forming machine, which can be used to solve the defects in the above technical background.

The guiding inclined plane is a smooth convex arc surface arranged obliquely and is fixed between the two side brackets. The copper foil produced in the copper foil forming machine is attached to the surface of the guiding inclined plane in a tensioned state and is continuously guided through the guiding inclined plane;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0019] SeeFigure 1 A preferred embodiment of the self - pressing device for the squeezing roller of a copper foil making machine. The self - pressing device for the squeezing roller of the copper foil making machine in this embodiment is an accessory structure arranged at the rear of the copper foil making machine, which is used to squeeze water and liquid from the copper foil produced by the copper foil making machine, so as to reduce the adhesion of electrolyte on the surface of the copper foil and facilitate further improvement of product quality in the subsequent processing process.

[0020] The self - pressing device for the squeezing roller of the copper foil making machine includes side brackets and connecting rods. The side brackets are the supporting structures of the functional main body of the self - pressing device for the squeezing roller of the copper foil making machine. The self - pressing device for the squeezing roller of the copper foil making machine is arranged on both sides of the foil - discharging path of the copper foil making machine through the side brackets, ensuring that the squeezing roller can accurately align with the advancing direction of the copper foil. The side brackets are made of high - strength alloy materials, having excellent corrosion resistance and mechanical strength to cope with various challenges in the production environment. Between the side brackets, they are strengthened and connected by connecting rods with adjustable lengths. This design not only enhances the stability of the overall structure but also allows for flexible adjustment according to the width of the copper foil and the specific specifications of the production line, ensuring that the squeezing roller can accurately cover the entire width of the copper foil and avoiding the problem of un - squeezed areas at the edges. Considering that in different embodiments, the structures of the side brackets and the connecting rods have no particularity and are only used for structural support, the drawings of this embodiment omit the display of the structural parts of the side brackets and the connecting rods.

[0021] The self - pressing device for the squeezing roller of the copper foil making machine also includes a pair of self - pressing adjustment mechanisms, and the two side self - pressing adjustment mechanisms are in a counter - supporting structure; the self - pressing adjustment mechanisms are assembled on the side brackets on both sides of the foil - discharging path of the copper foil making machine through the assembly frame 1.

[0022] The assembly frame 1 is fixedly assembled with a guide - material inclined - plane support 7 on the inner side, and the guide - material inclined plane 6 is assembled through the guide - material inclined - plane support 7. The surface of the guide - material inclined plane 6 is covered with stainless steel, and the stainless - steel surface is processed by mirror finishing or formed with a self - lubricating layer. The surface of the guide - material inclined plane 6 is the guiding plane for the copper foil 8 produced in the copper foil making machine. When the copper foil 8 passes through the guide - material inclined plane 6, it is introduced from the upper rear of the guide - material inclined plane 6 and led out in the tangential direction at the lower part of the guide - material inclined plane 6. The setting of the guide - material inclined plane 6 can enable the copper foil 8 to enter the squeezing - roller area in a tensioned state, and after the water and electrolyte on the surface are squeezed out by the squeezing roller, it enters the next process. In addition, the guide - material inclined plane 6 as a whole structure can be detachably assembled on the side brackets through the assembly frame 1.

[0023] The assembly frame 1 is provided with a fixing frame 12 on the outer side. The assembly frame 1 detachably assembles the self - pressing adjustment mechanism through the fixing frame 12. The self - pressing adjustment mechanism is used to assemble the squeezing roller and realize the close - fitting and adaptive pressure adjustment between the roller surface 9 of the squeezing roller and the guide - material inclined plane 6. And the detachable assembly method can facilitate the maintenance and replacement of the self - pressing adjustment mechanism, ensuring the continuity and high efficiency of the production line.

[0024] The self-pressure adjustment mechanisms on both sides are symmetric in structure and both include a base 5. The main body of the base 5 consists of two assembly plates arranged side by side. The two assembly plates have the same structure and are detachably assembled to the fixing frame 12 on both sides through threaded connectors.

[0025] A guiding chute is provided at the position below the assembly plate of the base 5. After the base 5 is assembled on the fixing frame 12, the guiding chute is in a horizontal state. An assembly gap is reserved between the two assembly plates of the base 5. A sliding seat 4, a ball screw pair 3, and a driving motor 2 are arranged at the position of the assembly gap of the base 5. The sliding seat 4 is assembled to the guiding chute on both sides and can slide along the guiding chute. A bearing seat 11 is provided on the upper part of the sliding seat 4. The bearing seat 11 is used for precisely installing the squeezing roller shafts 9 at both ends of the squeezing roller to ensure that the squeezing roller shafts 9 remain stable and have good coaxiality during rotation. To ensure the coaxiality stability of the squeezing roller during high-speed rotation operation, a high-precision bearing is embedded inside the bearing seat 11. By assembling the squeezing roller shafts 9 to the high-precision bearing, the friction and wear during the rotation of the squeezing roller shafts 9 can be reduced, and the overall operation efficiency and service life can be improved; the sliding seat 4 has a concave cavity on the outside, and a soft lining block is lined in the concave cavity. The outer surface of the soft lining block is flush with the outer surface of the sliding seat 4. The outer end of the ball screw pair 3 abuts against the outer surface of the soft lining block, and the driving part is assembled and connected to the driving motor 2. Through the combination of the driving motor 2 and the ball screw pair 3, not only an accurate moving track is provided for the sliding seat 4, but also the smoothness of the sliding seat during adjustment is ensured.

[0026] Correspondingly, the guiding chute provides a reliable path for the smooth movement of the sliding seat 4. By polishing the surface of the chute inside the guiding chute, the friction is reduced, making the sliding seat 4 more stable during adjustment and reducing the impact of vibration on the squeezing effect.

[0027] To further optimize the performance and reliability of the self-pressure device of the squeezing roller of the raw foil machine, an intelligent monitoring and feedback system can also be introduced on the basis of the structure of this embodiment. This system integrates high-precision pressure sensors, displacement sensors, and an intelligent control unit, realizing real-time monitoring and dynamic adjustment of the contact pressure and position between the squeezing roller and the copper foil.

[0028] Specifically, the pressure sensor is cleverly embedded between the squeezing roller shaft and the bearing seat, and can accurately measure and feedback the actual contact pressure of the squeezing roller on the copper foil surface. When the monitored pressure value deviates from the preset range, the intelligent control unit will immediately start the adjustment mechanism, and automatically correct the position of the sliding seat by adjusting the output power of the driving motor or the feed amount of the ball screw pair to ensure that a constant and optimal contact pressure is maintained between the squeezing roller and the copper foil. This design effectively solves the problem of pressure fluctuation caused by material thickness change or equipment wear, and further improves the stability and consistency of the squeezing effect.

[0029] In addition, displacement sensors are installed on both sides of the guiding chute to monitor the specific position of the sliding seat in the chute in real time. Combining with intelligent control algorithms, the data of the displacement sensors can assist the control unit to more precisely control the moving distance and speed of the sliding seat, achieving more refined position adjustment. This not only improves the adjustment accuracy, but also reduces the energy consumption and wear during the adjustment process, and extends the service life of the equipment.

[0030] The introduction of the intelligent monitoring and feedback system not only endows the self-pressing device of the squeezing roller of the copper foil machine with a higher level of automation and intelligence, but also significantly improves the stability and efficiency of the production line. Through real-time monitoring and dynamic adjustment, the device can adapt to changes under different production conditions, ensuring the continuous optimization of the water squeezing and liquid squeezing effects of the copper foil, and providing strong support for the high-quality development of the copper foil manufacturing industry.

[0031] In another embodiment, the driving motor 2 and the ball screw pair 3 can also be replaced by a manual structure, that is, an adjusting handle is set to directly drive the movement of the sliding seat 4 in the guiding chute. Although the automation level of this manual adjustment structure is reduced; although the manual adjustment structure is relatively lacking in terms of automation and intelligence, it has the advantages of low cost, simple maintenance, and flexible operation. In certain specific scenarios, the manual adjustment structure can also exhibit good performance and effects. For example, in the production line commissioning, emergency repair, or small-scale production environment, its simplicity and directness become significant advantages.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the use of these embodiments is only for explaining the present invention and is not intended to limit the protection scope of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications and / or variations to the present invention, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
