Pulling-plate-type bottle blank conveying mechanism of plastic bottle blowing machine

Abstract

The invention discloses a pulling-plate-type bottle blank conveying mechanism of a plastic bottle blowing machine. The pulling-plate-type bottle blank conveying mechanism comprises a blank feeding mechanism, a conveying mechanism, a heating device and a pulling-blowing mechanism which are arranged on a rack; the conveying mechanism comprises two annular tracks, conveying plates which are evenly and alternately laid are arranged between the two annular tracks, idler wheels are arranged on the inner side walls and the outer side walls of the conveying plates correspondingly and matched with thetwo annular tracks correspondingly, and every alternate conveying plates are movably connected through an upper pulling plate and a lower pulling plate; supporting shafts are arranged in the junctionsbetween the upper pulling plates and the conveying plates as well as between the lower pulling plates and the conveying plates, bottle blank inserting seats are arranged in the supporting shafts, andplastic bottle blanks are driven by the blank feeding mechanism to be inserted into the bottle blank inserting seats; and self-transmission chain wheels are arranged on the lower parts of the supporting shafts, the two annular positions of the two annular tracks are each provided with a large chain wheel, a revolution power part is arranged below one of the large chain wheels, wheel teeth of thelarge chain wheels extend into the position between every two adjacent supporting shafts, and the supporting shafts are driven by the revolution power part to drive the idler wheels on the conveying plates to operate on the annular tracks.

Description

technical field [0001] The invention relates to a plastic bottle blowing machine, in particular to a pull plate type preform conveying mechanism for a plastic bottle blowing machine, which belongs to the field of plastic machinery. Background technique [0002] Plastic hollow containers are produced by injection stretch blowing, such as mineral water bottles, oil bottles and cosmetic bottles. The plastic preform is transported to the stretch-blow mechanism for stretch-blow molding. Assembling the heating device, conveying mechanism and stretch blowing mechanism on the same frame, and equipped with an automatic billet feeding mechanism, is called a fully automatic plastic blow molding machine. Among them there is a full-automatic plastic blow molding machine, whose conveying mechanism includes an annular conveying track and conveying blocks evenly distributed on the conveying track, a preform seat is arranged in the conveying block, an auto-transmission gear is arranged outs...

AI Technical Summary

Problems solved by technology

The disadvantages are: 1. After a long time of use, the revolution chain will become loose and deformed, which will cause the origin of the revolution to shift and affect the preform transportation; 2. Only the outer side of the conveying block is provided with rollers, so the operation stability is poor and deviations are prone to occur
