Problems solved by technology

The preform loading device of the existing fully automatic plastic stretch blowing machine is a tube-taking manipulator installed above the template. When working, the tube-taking manipulator extends to the front outside of the template and clamps the bottle tube from the output port of the heating device. The disadvantages of it are: The tube manipulator needs to extend forward when it is working. When it is opened, the manipulator clamps the bottle tube by the jaws, and then moves back to send the bottle tube to the stretch blow mold. After stretching and blowing, the formed bottle is sent out and the jaws are opened, so The structure of the motion mechanism and control device is complicated, and the processing, installation and maintenance are troublesome

Abstract

The invention discloses an automatic blank feeding device of a full-automatic plastic drawing-blowing machine, comprising a rack, a template arranged on the rack, a mould, a mould opening and closing mechanism, a heating device and a bottle blank conveying mechanism. The automatic blank feeding device is characterized in that the mould is provided with a blank feeding device comprising a supporting board arranged on the rack or the mould, a plastic bottle blank guide cylinder is arranged in the supporting board, and the center of the guide cylinder is in line with the center of the mould; the mould mouth of a movable mould is provided with a blank receiving fork in contact with the plastic bottle blank. When the technical scheme works, a heated bottle blank is driven above the bottle blank guide cylinder by the bottle blank conveying mechanism, and the bottle blank can automatically fall into the guide cylinder; the center of the guide cylinder is in line with the center of the mould, so that the bottle can automatically fall into the mould; the blank receiving fork is arranged on the mould mouth of the mould, and then, the blank receiving fork automatically enters the mould for receiving the bottle blank, which has the advantages of accurate positioning, high working efficiency and time saving.

Description

technical field [0001] The invention relates to a plastic stretch-blow machine, in particular to an automatic billet loading device for a fully automatic plastic stretch-blow machine, and belongs to the field of plastic machinery. Background technique [0002] When the plastic hollow container is processed by the two-step method of injection molding and stretch blowing, the plastic raw material such as PET is first injected into a preform by the injection molding machine, and the preform needs to be heated by a heater for a second time, and then the heated preform is put into the stretch blowing machine Stretch blowing in the mold to form a bottle. In the existing technology, the heater and the stretch blowing machine can be combined on one machine. The preform heated by the heater can automatically enter the stretch blowing machine mold, which is called a fully automatic plastic stretch blowing machine. The preform loading device of the existing fully automatic plastic stre...
