Winding drum adjusting device of lithium battery slitting machine

Abstract

The invention discloses a winding drum adjusting device of a lithium battery slitting machine. The winding drum adjusting device comprises a machine frame, a paper feeding roller, a paper transferringroller and a tension roller, the paper feeding roller is connected with bearings on the machine frame through connecting shafts at the two ends of the outer wall of the paper feeding roller, L-shapedsupports are arranged on the two sides of the lower surface of the machine frame respectively, the paper transferring roller is connected with bearings on the L-shaped supports through connecting shafts at the two ends of the outer wall of the paper transferring roller, sliding grooves, fixing lugs and fixing blocks are arranged on the two sides of the upper surface of the machine frame respectively, and the sliding grooves, the fixing lugs and the fixing blocks are sequentially arranged from left to right; and the tension roller is connected with bearings on the fixing blocks through connecting shafts at the two ends of the outer wall of the tension roller, and the tension roller, the paper transferring roller and the paper feeding roller are sequentially arranged from left to right. According to the device, through the arrangement of a series of structures, the position of a winding drum on the lithium battery slitting machine is conveniently adjusted, the optimal degree of tightness of the winding drum during winding of slit membranes is achieved through the position adjustment, and the accuracy of slitting the membranes is improved.

Description

Technical field [0001] The invention relates to the technical field of slitting machines, in particular to a winding drum adjustment device of a lithium battery slitting machine. Background technique [0002] With the rapid development of the new energy industry, there is a great demand for the production of lithium battery separators and automotive power battery separators. The separators required for lithium batteries need to be slit to the corresponding width according to the battery specifications. The slit separators include dry film, wet film, and ceramic film. , The slitting requires fast speed, neat sides and low winding tension. Lithium battery slitting machine is an indispensable equipment for the production of related items. [0003] The current lithium battery slitting machine mainly includes a platform mechanism, an unwinding mechanism, a defect detection platform, a transition mechanism, and a winding mechanism. During the diaphragm cutting process, most of the windin...

Problems solved by technology

[0003] The current lithium battery slitting machine mainly includes a platform mechanism, an unwinding mechanism, a defect detection platform, a transition mechanism, and a winding mechanism. During the diaphragm slitting process, most of the winding drums do not have facilities to adjust the tension of the diaphragm. It cannot be adjusted. Due to the tension of the diaphragm, the size of the cut diaphragm will deviate when it is rolled on the reel. If the diaphragm with deviation is wound into a roll, the entire roll of diaphragm may be scrapped. room for improvement
