Converting assembly for flatulent or slip shafts with different diameters

Abstract

The invention relates to the field of a lithium ion battery and discloses a converting assembly for flatulent or slip shafts with different diameters. The converting assembly comprises three tiles with same shape and size and 120-degree radian and at least three rubber rings; mutually parallel grooves which are used together with the rubber rings are formed on an outer side wall of each tile; the quantity of the grooves is as same as the quantity of the rubber rings; the three tiles are spliced into a cylinder; the grooves on the outer side walls of the three tiles after being spliced are end-to-end jointed, and then concave rings which are mutually parallel to each other are formed on the outer side wall of the cylinder and the central axis of the cylinder is vertical to the concave rings; and the rubber rings are respectively sleeved in the concave rings so as to fix the three tiles into a whole cylinder converting assembly. The assembly is suitable for coiling and uncoiling reels in different sizes, is low in cost, is capable of conveniently switching the coiling and uncoiling reels in different sizes and is capable of effectively increasing the production efficiency.

Description

technical field [0001] The invention relates to the field of lithium-ion batteries, in particular to a conversion tool for air expansion or differential shafts with different diameters. Background technique [0002] At present, the pole piece rolling machine and pole piece shearing machine of our lithium battery front-end process, the air expansion / slip shaft for winding and unwinding are all customized in one size, and the die-cutting machine and winding machine used in the later stage Since the winding machine involves different manufacturers and different process requirements, it is useful to use different sizes of reels for rewinding and unwinding. The existing roller presses and slitters cannot simultaneously take care of the rewinding and unwinding requirements of the subsequent equipment.

Problems solved by technology

[0002] At present, the pole piece rolling machine and pole piece shearing machine of our lithium battery front-end process, the air expansion / slip shaft for winding and unwinding are all customized in one size, and the die-cutting machine and winding machine used in the later stage Since the winding machine involves different manufacturers and different process requirements, it is useful to use reels of different sizes. The existing roller presses and slitting machines cannot simultaneously take care of the rewinding and unwinding requirements of the subsequent equipment.

If two reels with different specifications need to be rewound and unwound, two special air expansion / slip shafts need to be designed separately, which is expensive, long cycle, and troublesome and time-consuming to replace, especially the sliding shaft of the shearing machine. The differential shaft is connected with the equipment, and it takes time and effort to disassemble and assemble. If the two reels are frequently switched during the production process, it will seriously affect the production plan. Therefore, it is urgent to develop a convenient and fast air expander suitable for different diameters. Or slip shaft conversion tooling
