Description

Technical Field

[0001] This utility model belongs to the field of foil material conveying technology, specifically relating to a conveyor for negative electrode coated foil material. Background Technology

[0002] Aluminum foil and other foil materials, after being corona-treated, are processed through negative pressure coating, rolling, slitting, and winding to become the negative electrode current collector for sodium-ion batteries. The movement of the foil materials between these processes is accomplished by conveyors.

[0003] Chinese patent document CN222063599U discloses a conveying device for negative electrode coated foil. It uses a main roller with a larger diameter in the middle and smaller diameters on both sides to cooperate with a pressure roller located above the junction of the main roller and the auxiliary roller, so that the foil is tightly attached to the main roller, thereby avoiding the foil from curling or wrinkling.

[0004] However, in the existing technology, although the foil is properly clamped, the clamping force is relatively fixed and not easy to adjust. When the foil breaks accidentally during the conveying process, the foil near the break point is prone to shrinking or sliding away from the break point due to the sharp decrease in tension. In severe cases, it may even fall out of the conveying device, resulting in large-area deformation of the foil and turning it into waste. Therefore, a conveyor for negative electrode coated foil is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a conveyor for negative electrode coated foil.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A conveyor for negative electrode coated foil includes a frame in which the conveyor can be installed in a foil conveying line. The frame is provided with a conveying component that can clamp the foil to limit its movable range during conveying. Anti-detachment components are provided at the front and rear of the frame to further clamp the foil when it retracts or slides due to accidental breakage.

[0008] The conveying assembly includes idler rollers movably mounted within the frame, with pressure rollers positioned above the idler rollers;

[0009] The anti-detachment assembly includes a lifting component that can activate the anti-detachment assembly when the idler roller reverses due to the accidental breakage of the foil it is holding, a pressing component that can move the pressure roller a certain distance toward the idler roller after the anti-detachment assembly is activated, and a transmission component that can change the direction of the power from the lifting component and transmit it to the pressing component.

[0010] The lifting component includes a first bracket fixedly connected to one side of the frame, a vertical rod movably connected to the first bracket, a pawl movably connected to the lower end of the vertical rod, and ratchet wheels fixedly connected to the front and rear ends of the idler roller.

[0011] The pressing component includes a second bracket fixedly installed on the other side of the frame, a bent rod movably installed inside the second bracket, and a pressing frame movably connected to the bent rod.

[0012] Preferably, the transmission component includes a shaft seat fixedly connected to one side of the first bracket and the second bracket respectively, a rack fixedly connected to one side of the upright rod and the bent rod, a rotating shaft movably connected between adjacent shaft seats, and two gears fixedly connected to the outer side of the rotating shaft.

[0013] Preferably, the pressing component further includes a second spring disposed between the second bracket and the bending rod, and a locking rod is provided on one side of the bending rod.

[0014] Preferably, the first bracket is slidably connected to the upright, and the upright is rotatably connected to the pawl.

[0015] Preferably, both the second support and the pressure frame are slidably connected to the bending rod.

[0016] Preferably, the bearing seat is rotatably connected to the shaft, and the adjacent rack is meshed with the gear.

[0017] Preferably, the bending rod and the locking rod are connected by threads.

[0018] The beneficial effects of this utility model are as follows: By setting up a ratchet in the lifting component that can rotate synchronously with the idler roller and a pressure frame in the pressing component that can rise and fall together with the pressure roller, the anti-detachment component can be activated at the moment when the idler roller, pressure roller, and ratchet reverse due to accidental breakage of the foil. The pressure frame presses the pressure roller against the idler roller by a certain distance, so that the idler roller and pressure roller can further clamp the foil to limit the disorderly movement when the foil breaks, thereby preventing the foil from deforming over a large area and becoming waste.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figures 1-5As shown, a conveyor for negative electrode coated foil includes a frame 1 in which the conveyor can be installed in a foil conveying line. The frame 1 is provided with a conveying component 2 that can clamp the foil to limit its movable range during conveying. The frame 1 is provided with anti-detachment components 3 at the front and rear of the frame 1 to further clamp the foil when it retracts or slides due to accidental breakage.

[0031] In this embodiment, the frame 1 provides installation positions for key components such as the fixed roller seat 201, the limiting block 203, the first bracket 301, and the second bracket 305, so that the conveyor can be moved as a whole when the frame 1 moves, so that the conveyor can be arranged in the foil conveying line for use.

[0032] In this embodiment: the conveying assembly 2 includes fixed roller seats 201 fixedly installed in front and rear of the frame 1 respectively, a support roller 202 movably connected between the two fixed roller seats 201, limit blocks 203 fixedly connected to the front and rear of the frame 1, a limit rod 204 provided between the frame 1 and the limit block 203, a movable roller seat 205 provided between the adjacent limit rod 204 and the frame 1, a pressure roller 206 movably connected between the two movable roller seats 205, a first spring 207 provided between the movable roller seat 205 and the frame 1, a screw 208 provided on the limit block 203, a handle 209 fixedly connected to the upper end of the screw 208, and a gasket 210 fixedly connected to the lower end of the screw 208;

[0033] The fixed roller seat 201 is rotatably connected to the support roller 202. The frame 1 and the limiting rod 204 are slidably connected to the movable roller seat 205. The movable roller seat 205 is rotatably connected to the pressure roller 206. The limiting rod 204 is slidably connected to the first spring 207. The limiting block 203 is threadedly connected to the screw 208.

[0034] The fixed roller seat 201 and the movable roller seat 205 respectively limit the movable range of the idler roller 202 and the pressure roller 206 in this conveyor. The limit block 203 provides the installation position for the limit rod 204 and the screw 208. The frame 1, the limit rod 204, the first spring 207 and the screw 208 together limit the movable range and position change of the movable roller seat 205. The frame 1 and the limit rod 204 enable the movable roller seat 205 to rise and fall vertically together with the pressure roller 206 only in this conveyor. The first spring 207 can provide support for the movable roller seat 205, making its rise and fall smoother. The pad 210 that replaces the screw 208 in contact with the movable roller seat 205 can stably apply pressure to the movable roller seat 205 when the operator rotates the screw 208 through the handle 209, thereby adjusting the height difference between the pressure roller 206 and the idler roller 202.

[0035] In this embodiment: the anti-detachment component 3 includes a lifting member that can activate the anti-detachment component 3 when the idler roller 202 reverses due to the accidental breakage of the foil it is holding; a pressing member that can move the pressure roller 206 a certain distance toward the idler roller 202 after the anti-detachment component 3 is activated; and a transmission member that can change the direction of the power from the lifting member and transmit it to the pressing member.

[0036] The lifting component includes a first bracket 301 fixedly connected to one side of the frame 1, a vertical rod 302 movably connected to the first bracket 301, a pawl 303 movably connected to the lower end of the vertical rod 302, and ratchet wheels 304 fixedly connected to the front and rear ends of the roller 202. The pressing component includes a second bracket 305 fixedly installed on the other side of the frame 1, a bent rod 306 movably installed in the second bracket 305, and a pressure frame 307 movably connected to the bent rod 306. The transmission component includes a bearing seat 308 fixedly connected to one side of the first bracket 301 and the second bracket 305 respectively, a rack 309 fixedly connected to one side of the vertical rod 302 and the bent rod 306, a rotating shaft 310 movably connected between adjacent bearing seats 308, and two gears 311 fixedly connected to the outer side of the rotating shaft 310. The pressing component also includes a second spring 312 disposed between the second bracket 305 and the bent rod 306, and a locking rod 313 disposed on one side of the bent rod 306.

[0037] The first bracket 301 is slidably connected to the upright 302, the upright 302 is rotatably connected to the pawl 303, the second bracket 305 and the pressure frame 307 are both slidably connected to the bending rod 306, the bearing seat 308 is rotatably connected to the rotating shaft 310, the adjacent rack 309 is meshed with the gear 311, and the bending rod 306 is threadedly connected to the locking rod 313.

[0038] The movable range of the upright 302, whose lower end is connected to a pawl 303, is limited by the first bracket 301. The pawl 303 limits the rotation direction of the ratchet 304 that rotates with the pressure roller 206. The movable range of the bending rod 306 is limited by the frame 1, the second bracket 305, and the second spring 312. The rotating shaft 310 is installed by two bearing seats 308 connected to the first bracket 301 and the second bracket 305, respectively. The height change of the upright 302 is transmitted to the meshed gear 311 by the rack 309 connected to the upright 302, so that the gear 311 drives the rotating shaft 310 to rotate relative to the bearing seat 308. After rotation, the rotating shaft 310 can be driven by another gear 311. 1. The rack 309 connected to the bending rod 306 drives the bending rod 306 to move in the opposite direction to the upright rod 302, and rises and falls relative to the second support 305. The height change of the bending rod 306 is transmitted to the movable roller seat 205 through the pressure frame 307. The second spring 312 provides support for the bending rod 306 to appropriately overcome the influence of its own weight on the height change of the movable roller seat 205. The contact between the locking rod 313, which can be tightened and loosened, and the side of the pressure frame 307 adjusts the friction between the pressure frame 307 and the bending rod 306, so that the operator can adjust the height of the pressure frame 307 relative to the bending rod 306, or lock the height of the pressure frame 307 on the bending rod 306.

[0039] Working Principle: When this conveyor is installed for conveying negative electrode coated foil, it should be installed perpendicular to the foil conveying direction in the foil conveying line. The installation height should be such that the foil can pass between the idler roller 202 and the pressure roller 206. After installation, loosen the locking rod 313, then rotate the screw 208 through the handle 209 to apply pressure to the movable roller seat 205 with the shim 210. This allows the idler roller 202 and the pressure roller 206 to properly clamp the foil between them, and the V-shaped part of the pressure frame 307 should always rest on the movable roller seat 205. After clamping, tighten the locking rod 313. Furthermore, during subsequent foil conveying, the idler roller 202 should rotate counterclockwise and the pressure roller 206 should rotate clockwise. After the above preparations are complete, the foil passing through this conveyor can be pulled by external tensioning equipment, allowing the foil to travel in the conveying line at the required speed.

[0040] During the movement, the ratchet 304, which rotates counterclockwise with the idler roller 202, can continuously move the pawl 303. However, since the height change of the movable roller seat 205 is limited by the first spring 207 and the screw 208, when the locking rod 313 locks the height of the pressure frame 307, the pressure frame 307 on the movable roller seat 205 can prevent the bending rod 306 from falling. Since the bending rod 306 can react to the upright rod 302 through the rack 309, gear 311 and other components, the height of the upright rod 302 will not change when the ratchet 304 rotates normally, although the pawl 303 is moved, thus ensuring the stable operation of the conveyor.

[0041] However, when the foil breaks unexpectedly and retracts or slips, because the idler roller 202 and pressure roller 206 are in close contact with the foil, the retraction or slippage of the foil will cause the idler roller 202 and pressure roller 206 to stop abruptly and reverse. Since the ratchet 304 rotates synchronously with the idler roller 202, when the ratchet 304 reverses, it will lift the pawl 303. The lifted pawl 303 will drive the upright 302 to move upward relative to the first support 301. The upward movement of the upright 302 will be transmitted to the bending rod 306 through the rack 309, gear 311 and other components, so that the bending rod 306 will press down on the movable roller seat 205 through the pressure frame 307. Therefore, after the foil breaks, once the ratchet 304 reverses, the pressure frame 307 will apply pressure to the movable roller seat 205, so that the pressure roller 206 is close to the idler roller 202 to further clamp the foil, thereby limiting the foil from retracting, slipping or detaching from the conveyor.

[0042] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
