Description

Bottle embryo reason embryo distance conveyor of bottle blowing machine Technical Field The utility model relates to the technical field of bottle embryo conveying, in particular to a bottle embryo arranging and spacing conveying device of a bottle blowing machine. Background The heating energy consumption of bottle blowing machine is the biggest part in whole production line, traditional bottle blowing machine does not have pitch-changing device, the interval of bottle embryo seat and the interval equidistance in mould bottle chamber, lead to the heat utilization ratio greatly reduced of heating fluorescent tube, can realize through bottle embryo pitch-changing mechanism of bottle blowing machine, the interval between bottle embryo and the bottle embryo is less than the mould die cavity interval when the bottle embryo heats, in the fluorescent tube region of same length, the heating quantity of bottle embryo compares with traditional bottle embryo pitch-changing mechanism of bottle embryo that does not have bottle blowing machine and increases several times, the utilization ratio of fluorescent tube heat energy has been promoted by a wide margin, reach energy-conserving purpose. The existing bottle embryo pitch-changing mechanism of the bottle blowing machine consists of a plurality of push rods with guide heads, adjacent push rods are linked by a chain with set length, the last push rod at the downstream end is connected with a piston rod of a cylinder, the cylinder drives the last push rod when the pitch is changed, the last push rod pulls the chain, after the chain is straightened, the next push rod is pulled by the chain, the next push rod pushes the chain again, after the chain is straightened, the next push rod is pulled by the chain again, and so on.
