The invention relates to a cap assembling device which is used for assembling kettle caps,
bottle caps and other combined type caps. The cap assembling device is characterized in that a cap combining device comprises a divided plate, a plurality of locating components are arranged on the divided plate along the periphery, and a concave-convex
station sliding rail is arranged below the divided plate in a surrounding mode and located at the position which is aligned to the locating components vertically. The locating components comprise screening blocks, locating pads, and a guide
assembly which is arranged below the screening blocks and the locating pads and used for changing the
vertical distance between the locating pads and the screening blocks. The screening blocks and the locating pads are used for locating raw materials, and the lower end of the guide
assembly is connected with the
station sliding rail. The cap combining device in a divided plate mode is used, connection of upper caps and lower caps is controlled intelligently and finished automatically, and a lower cap conveying device, an upper cap conveying device, a paster conveying device, an
output device and the like are combined, so that the complete process from feeding to output of finished products of kettle caps is finished orderly and compactly.
Production automation is improved, and assembling efficiency of the kettle caps, the
bottle caps and other combined type caps is improved.
