Abstract

The invention relates to a sliding type double-cohesion stepping and driving bottle blowing machine, which comprises a machine frame (1), a bottle preform seat transporting device (2), a driving device (3), a mould locking device (4) and a heating system (5). The machine is characterized in that the bottle preform seat transporting device (2) has a sliding type transporting structure and consists of an annular slide rail (2-1) and a slide block (2-2); the driving device (3) has a double-cohesion type stepping and pneumatic driving structure and comprises a stepping and pneumatic driving mechanism and a double-cohesion clutching mechanism; the stepping and pneumatic driving mechanism comprises a stepping cylinder (3-1) and a positioning cylinder (3-2); the double-cohesion clutching mechanism consists of opposite claws (3-3) and claws (3-2); the mould locking device has a gas-liquid interacting structure and comprises a gas-liquid pressure cylinder (4-1) and a mould locking mechanism (4-10) ; and the gas-liquid pressure cylinder (4-1) is connected with the mould locking mechanism (4-10) through a shaft coupler. The machine has the advantages of high accuracy for transporting workpieces, low noise, stable bottle blowing, simple whole structure, small volume, convenient use and maintenance, and low cost.

Description

technical field [0001] The invention relates to a bottle blowing machine, in particular to a sliding double-clinging step-driven bottle blowing machine, which is widely applicable to blowing PP plastic bottles or PET plastic bottles of various specifications. It belongs to the technical field of equipment for blowing plastic containers from preforms. Background technique [0002] The equipment that blows plastic containers from preforms is commonly known as blow molding machine. Most of the blow molding machines in the prior art use an endless chain to drive the movement of the preform seat in its preform seat conveying device, and the preform seat is sent to each station by the rotation of the chain to carry out the corresponding blowing process. This kind of conveying mechanism driven by a chain has the following disadvantages: (1) the transmission is not stable, easy to shake, and the accuracy of the workpiece positioning is poor; (2) the structure is complicated, the ma...
