Bottle blowing machine

Abstract

The invention relates to a bottle blowing machine. The machine comprises a frame, a die opening and closing assembly, a lift assembly, a bottom die locking assembly and a drive assembly, wherein the die opening and closing assembly comprises a bottom die, a fixed template and a movable template; the lift assembly comprises a cam, a lift rod and a pulley, a runner is formed on the cam, the pulley is slidably arranged in the runner, and the bottom die is fixed on the lift rod; the bottom die locking assembly comprises a driving connection block, a driven connection block, a first slide block and a second slide block, the first slide block is slidably arranged on the frame, and the second slide block is fixed on the movable template; the drive assembly comprises a rotating shaft and a power source; the movable template, the cam and the driving connection block are fixedly connected with the rotating shaft at the same time; and when the rotating shaft is rotated, a die is closed by the fixed and movable templates, and the bottom die rises and the first and second slide blocks slide between the frame and the bottom die. The bottle blowing machine can be used for driving the three assemblies to act at the same time through only one rotating shaft, and completing die closing, lifting and locking steps, and is simple in structure and convenient to operate, so that the efficiency of bottle blowing process can be improved.

Description

technical field [0001] The invention relates to a bottle blowing machine. Background technique [0002] Blow molding machine: It is a machine that can blow plastic particles (softened into liquid) or preforms into bottles through certain technological means. The bottle blowing machine includes a mold opening and closing mechanism, a bottom mold lifting mechanism, a bottom mold locking mechanism and a driving mechanism. [0003] The traditional mold opening and closing mechanism adopts a frame, and the fixed template and the movable template are installed on the frame. There is a mold locking mechanism at the junction of the fixed template and the movable template. The movable template is L-shaped and driven by the mold opening and closing cylinder. The cylinder drives the rack, the rack drives the movable template gear, the movable template gear is arranged on the pinion shaft, the pinion shaft connects the movable template, and the pinion shaft is installed on the support....

AI Technical Summary

Problems solved by technology

It can be seen that the bottle blowing machine in the prior art has a complex structure, the equipment is bulky, and is driven separately, which is not conducive to operation and is expensive.
