Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery pole piece processing, in particular to a roller pressing machine for soft-pack lithium battery pole pieces. Background Art

[0002] Soft-pack lithium battery is a new type of lithium-ion battery with the advantages of small size, light weight and high energy density. Therefore, it is widely used in mobile electronic devices, electric vehicles and energy storage fields. The production process of soft-pack lithium battery mainly includes four steps: preparation of positive electrode materials, preparation of negative electrode materials, battery assembly and packaging. Among them, the preparation of positive and negative electrode materials often requires the use of rolling equipment to prepare them into corresponding pole pieces. Traditional rolling equipment mostly uses double rollers to rotate and extrude the positive and negative electrode materials to form corresponding positive and negative pole pieces. However, during the rolling process, the sides of the pole piece material will deform and extend outward, making the pole piece size non-standard and irregular. It is often necessary to perform subsequent side cutting operations on the pole piece after rolling, which will reduce the overall processing efficiency of the pole piece. Utility Model Content

[0003] The purpose of the utility model is to provide a rolling processing machine for soft-pack lithium battery pole pieces, which can vertically and synchronously cut off the excess extension of the side of the lithium battery pole piece that is deformed by rolling, ensure that the pole piece output after rolling is standardized, eliminate the need for subsequent cutting, and improve processing efficiency.

[0004] The cam is secured to the chassis and has a first end secured thereto and a second end secured thereto, the second end secured to the chassis being secured to the chassis. The right sides of the motor and the synchronous motor are fixedly connected to the slide and the bearing seat respectively, and an electric push rod is symmetrically arranged on the left and right sides just above the second roller shaft, and the electric push rods are all fixed with the frame, and the output ends on the opposite sides of the electric push rods are fixedly connected with a triangular ring seat, and the center of the opposite side of the triangular ring seat is fixedly connected with a triangular cutter, and a recovery box is arranged on the lower rear side of the second roller shaft, and the recovery box is downwardly engaged with the frame and slidably connected with it, and the excess extension of the side edges of the deformed lithium battery pole pieces by rolling is vertically and synchronously cut off by symmetrically arranging triangular cutters on both sides between the roller shafts, so as to ensure the standard of the pole pieces output after rolling, without the need for later cutting, thereby improving the processing efficiency, and in addition, the electric push rod is used to freely adjust the horizontal and horizontal spacing of the triangular cutters, so as to freely determine the lateral size of the rolled pole pieces, which is suitable for cutting requirements of pole pieces of different sizes and improves the flexibility of its cutting edge.

[0005] According to the roll-pressing machine for soft-pack lithium battery pole pieces, the triangular ring seat and the triangular cutter thereon are both shifted rearward so that the front corner of the triangular cutter is directly above the second roller axis. This ensures that excess pole pieces caused by compression, extension, and deformation on both sides after rolling are removed.

[0006] According to the roller-pressing machine for soft-pack lithium battery pole pieces, a sanding plate is fixedly connected to the inner bottom of the recycling box to prevent high-temperature waste from sticking to the recycling box and affecting recycling efficiency.

[0007] According to the roller pressing machine for soft-pack lithium battery pole pieces, a handle is fixedly connected to the center of the rear side of the recycling box, which facilitates the removal of the recycling box and the cleaning and recycling of the waste materials removed therefrom.

[0008] According to the roller-pressing machine for soft-pack lithium battery pole pieces, a handle is fixedly connected to the top center of the frame, which facilitates the rapid transfer of the entire machine.

[0009] According to the roller-pressing machine for soft-pack lithium battery pole pieces, anti-skid pads are fixedly connected to the bottom of the frame in a cross-symmetrical manner to maintain the stability of the entire device during installation.

[0010] According to the roller-pressing machine for soft-pack lithium battery pole pieces, the bottom of each electric push rod is fixedly connected to a horizontal limit rod, and the opposite ends of each horizontal limit rod are fixedly connected to the frame to maintain the horizontal and linear output of the electric push rod.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In the utility model, triangular cutters are symmetrically set up on both sides between the rollers to vertically and synchronously cut off the redundant extension of the side edges of the deformed lithium battery pole pieces after rolling, thereby ensuring that the pole pieces output after rolling are standardized and do not need to be cut later, thereby improving processing efficiency. In addition, the electric push rod is used to freely adjust the horizontal spacing of the triangular cutters, so that the horizontal size of the rolled pole pieces can be freely determined, which is suitable for the cutting requirements of pole pieces of different sizes and improves the flexibility of its cutting edge.
