Description

Technical Field

[0001] This application relates to the technical field of lead-acid battery separator production equipment, specifically a three-roller thickness fixing device for a battery separator production line. Background Technology

[0002] Lead-acid batteries are secondary batteries that use lead and its oxides as electrodes and sulfuric acid solution as electrolyte. They are widely used in transportation, energy storage, power and other fields. In order to prevent short circuits between the positive and negative electrodes of lead-acid batteries, a separator is installed inside the lead-acid battery. This separator allows electrolyte ions (such as H⁺, SO₄²⁻) to diffuse freely, and at the same time, it acts as an electrolyte carrier to promote the efficient electrochemical reaction. Common applications of lead-acid battery separators: 1. Car starting, lighting, ignition (SLI), this is the most common use.

[0003] 2. Uninterruptible power supply (UPS): Provides backup power for servers, data centers, and medical equipment.

[0004] 3. Electric vehicles: electric bicycles, motorcycles, forklifts, and golf carts.

[0005] 4. Renewable energy storage: Energy storage units for solar and wind power generation systems.

[0006] 5. Boats and RVs: Provide electricity for daily life.

[0007] 6. Emergency lighting equipment.

[0008] The traditional method for producing lead-acid battery separators involves using a five-roll forming machine (two vertical rolls for forming, two vertical rolls for thickness determination, and a large cooling roll) to shape the sheet material extruded from the die. The die is a horizontal extrusion type, which makes it prone to sag, making it difficult to control the thickness tolerance and surface quality of the separator. Furthermore, the forming and thickness determination equipment is too bulky, causing steel deformation during processing and resulting in errors that affect the equipment's precision. Transportation and installation are also inconvenient, and the limited space for inserting the separators during startup leads to low production efficiency. Therefore, it is necessary to provide a three-roll thickness determination device for the battery separator production line to solve these problems.

[0009] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0010] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a three-roller thickness fixing device for a battery separator production line, which solves the problem that the thickness and surface quality are difficult to control in the existing lead-acid battery separator production process.

[0011] The technical solution adopted by this application to solve its technical problem is: a three-roller thickness fixing device for a battery separator production line, including a frame, a first support installed at the bottom of the frame, a first steel roller with power and a second steel roller with power rotatably mounted on the first support, and a first gap between the first steel roller and the second steel roller for the passage of the battery separator; A powered third steel roller is rotatably mounted on the top of the frame. The third steel roller is used to guide the battery separator out and cool and shape it. The frame is equipped with a movable fixed seat, and a first front transition steel roller and a second front transition steel roller are mounted on the fixed seat with bearings, and a second gap exists between the first front transition steel roller and the second front transition steel roller. An extension frame is mounted on the frame, on which a first rear transition steel roller and a powered second rear transition steel roller are rotatably mounted. Rotary joints are provided at both ends of the first steel roller, the second steel roller, and the third steel roller.

[0013] Furthermore, a gap adjuster is provided between the first steel roller and the second steel roller.

[0014] Furthermore, a geared motor is fixedly mounted on the frame, and a lead screw is fixedly mounted on the output end of the geared motor. The lead screw is mounted to the frame bearing, and a fixed seat is driven onto the lead screw. The fixed seat is slidably mounted on the frame.

[0015] Furthermore, an electrostatic eliminator is installed on the extension frame.

[0016] The beneficial effects of this application are: the three-roll thickness fixing device for the battery separator production line provided by this application can compact and cool the pre-formed lead-acid battery separator pulled out from the two-roll forming machine through the three-roll thickness fixing device, thereby quickly producing lead-acid battery separators, solving the problem that the thickness and surface quality are difficult to control in the existing lead-acid battery separator production process.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

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

[0021] like Figures 1-4 As shown, this application provides a three-roller thickness fixing device for a battery separator production line, including a frame 1, the bottom of which is provided with casters 17 to facilitate the movement of the frame 1 into the processing area; Meanwhile, cylinders 16 are fixedly installed at both ends of the bottom of the frame 1. A first bracket is fixedly installed at the output end of the cylinder 16, and a vertical guide rail 3 is installed on the frame 1. The first bracket is slidably installed on the guide rail 3, so that the first bracket can slide vertically along the guide rail 3 under the extension and retraction of the cylinder 16. A first servo motor 21 is fixedly installed on one of the first brackets. A first steel roller 2 is fixedly installed on the output end of the first servo motor 21. The first steel roller 2 is mounted with bearings on both sets of first brackets, so that when the first servo motor 21 is started, it can drive the first steel roller 2 to rotate. Continue to refer to Figures 1-4 Two sets of second brackets are fixedly installed on the frame 1. The second brackets are located above the first bracket. A second servo motor 22 is fixedly installed on one of the second brackets. A second steel roller 5 is fixedly installed on the output end of the second servo motor 22. The second steel roller 5 is mounted with bearings on both sets of second brackets. Starting the second servo motor 22 can drive the second steel roller 5 to rotate. It should be noted that the first steel roller 2 can move closer to or further away from the second steel roller 5 as the first support moves vertically, thereby adjusting the gap between the first steel roller 2 and the second steel roller 5, and thus adapting to the forming of battery separators of different thicknesses. Furthermore, a gap adjuster 4 is provided between the first steel roller 2 and the second steel roller 5 to facilitate fine-tuning of the gap between the first steel roller 2 and the second steel roller 5.

[0022] like Figures 1-4 As shown, a first bearing seat 30 and a second bearing seat 31 are fixedly installed on both sides of the upper end of the frame 1, respectively. A third steel roller 29 is installed on the first bearing seat 30 and the second bearing seat 31, and a third servo motor 23 is fixedly installed on the frame 1. A belt transmission mechanism is installed at the output end of the third servo motor 23. The output end of the belt transmission mechanism is fixedly installed with the third steel roller 29, so that when the third servo motor 23 works, it can drive the third steel roller 29 to rotate. It should be noted that the belt transmission mechanism includes a drive pulley 25 fixedly installed at the output end of the third servo motor 23, and a passive pulley 26 fixedly installed on the third steel roller 29. A synchronous belt 27 is provided between the passive pulley 26 and the drive pulley 25 for transmission. Thus, the third servo motor 23 can drive the third steel roller 29 to rotate through the cooperation of the drive pulley 25, the synchronous belt 27 and the passive pulley 26. In order to guide the formed battery separator, a front transition mechanism is provided on the frame 1. The front transition mechanism includes a geared motor 12 fixedly installed on the frame 1. A lead screw 8 is fixedly installed at the output end of the geared motor 12. The lead screw 8 is installed with the bearing of the frame 1, so that when the geared motor 12 works, it can drive the lead screw 8 to rotate. Meanwhile, a fixed seat 9 is provided on the lead screw 8 for transmission. The fixed seat 9 is slidably installed on the frame 1, so that when the lead screw 8 rotates, it can drive the fixed seat 9 to adjust its position on the frame 1. Furthermore, a first front transition steel roller 10 and a second front transition steel roller 11 are mounted on the fixed base 9, with a gap between the first front transition steel roller 10 and the second front transition steel roller 11 for guiding the front end of the battery separator.

[0023] like Figures 1-4 As shown, a rear transition mechanism is also provided on the frame 1. The rear transition mechanism includes an extension frame 6 fixedly installed on the frame 1. A fourth servo motor 24 is fixedly installed on the extension frame 6. A second rear transition steel roller 14 is fixedly installed at the output end of the fourth servo motor 24. At the same time, a first rear transition steel roller 13 is mounted on the extension frame 6. Thus, the formed battery separator is transported to the next process through the first rear transition steel roller 13 and the second rear transition steel roller 14.

[0024] It should be noted that a rotary joint 18 is provided at both ends of the first steel roller 2, the second steel roller 5 and the third steel roller 29. The rotary joint 18 is used to introduce the medium into the steel roller so as to control the temperature of the steel roller. Furthermore, an electrostatic eliminator 15 is installed on the extension frame 6, which is used to eliminate static electricity during the molding of the battery separator. In summary, the three steel rollers of the three-roll thickness fixing device are arranged vertically. The pre-formed battery separator pulled out from the two-roll forming machine (horizontally arranged) is pulled through the gap between the first front transition steel roller 10 and the second front transition steel roller 11 mounted on the fixed seat 9 to the first steel roller 2 and the second steel roller 5. The fixed seat 9 can move up and down through the forward and reverse rotation of the reduction motor 12 and the transmission through the lead screw 8. Thus, the wrap angle of the battery separator with the first steel roller 2 and the second steel roller 5 can be changed. The first steel roller 2 is given an upward lifting force by the cylinder 16, and the gap between it and the second steel roller 5 is adjusted by the gap fine adjuster 4. This can adapt to the needs of battery separators of different thicknesses and varieties and can achieve rapid switching. Then the battery separator with the fixed thickness is simultaneously pulled onto the third steel roller 29 (large diameter cooling steel roller) with power for cooling and shaping. The first steel roller 2, the second steel roller 5 and the third steel roller 29 are all connected to a rotary joint 18 with water temperature control. The battery separator, cooled and shaped by the third steel roller 29 (large diameter cooling steel roller), is then pulled over the first rear transition steel roller 13 and the second rear transition steel roller 14, as well as the static eliminator 15, to the next process.

[0025] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
