Lifting gear of cap whirling machine

Abstract

A screw cover retractor device of a screw cover machine comprises a supporting frame, two screw retractor components, a motor, a motor gear and a gear idle. The screw retractor components are arranged at the supporting frame. The motor drives the screw retractor components turning by the gear idle. The flexing of screw cover tie-ins is drove by a cylinder. The cylinder is communicated with pressure air source and controlled by a control circuit. Adopting the device, a motor can synchronously drive two screw retractor components and can synchronously and tightly screw two covers once, screwing cover efficiency can be increased by one time by comparing with the prior technology. By adopting quick disappearing end bumper of the cylinder driving disappearing end bumper axis of rotation, the rapid flexible prepressing approach of the screw cover tie-ins and the covers is implemented. A reset spring can ensure the bottle covers and the bottle mouths are in a compressing condition all the time and can also automatically adjust bottle cover winding moment to ensure the screw cover tie-ins wind up the moments of the bottle covers, etc, automatically avoid screwing loosely or in a fractured state due to dimension errors of the bottle covers and the bottle height.

Description

Technical field: [0001] The invention relates to a bottle filling machine or capping machine, in particular to a capping lifting device. Background technique: [0002] The bottle capping machines commonly used now are disc-type capping machines, which consist of a continuously rotating circular worktable and several capping joints distributed in the same circle. The capping joints are located above the circular workbench. The height does not change when working, and there are bottle placement stations corresponding to the screw cap joints on the disc, and bottle body lifting devices corresponding to each bottle body station on the circular workbench, all lifting devices are controlled by It consists of a tappet and an end cam. When the tappet on the turntable turns to the highest point of the end cam, the bottle cap is in the tightening position. There is only one tightening station among all the stations on the turntable. The disc rotates continuously, and the bottle caps a...

AI Technical Summary

Problems solved by technology

[0003] ①The production efficiency is low, only one bottle cap can be tightened at a time

[0004] ②During the capping process, since the bottle body is pushed up by the end face cam and the tappet, the distance between the bottle mouth and the screw cap joint is a fixed value, and there are errors in both the bottle body and the bottle cap, and they are different from the bottle body. The contact and compression method of the cap is a rigid compression method, and the probability of crushing the bottle cap or not being able to press the bottle cap is high, which cannot ideally meet the packaging requirements of screw caps
