Reciprocating open type equipment for fetching and sending semi-finished bottles or shaped bottles

Abstract

The reciprocating opening type preform or molded bottle pick-up and delivery device has a pair of template seats, and the mold opening and closing cylinder is installed in the template seat. One end of the plate is connected to power, and the other end of the reciprocating plate is connected to an open-type plastic preform or molded bottle clamping mechanism, which is characterized in that the open-type plastic preform or molded bottle clamping mechanism includes a There are cams on both sides of the left and right retrieving pliers, fixed clips are installed on the template seat, and a support spring is installed at one end of the two pliers. The other end of the pliers is formed with an opening for feeding and clamping.

Description

technical field [0001] The invention relates to parts of a plastic bottle blowing machine, mainly relates to a pick-up and delivery device for plastic bottle blanks, and belongs to processing equipment for plastic hollow containers. Background technique [0002] Using plastic as raw material, injection stretch blowing or extrusion blowing is used to produce various packaging containers, such as beverage bottles, medicine bottles, etc. The main equipment is plastic stretch blowing machine or plastic extrusion blowing machine (both are called plastic container forming blow molding machine ). Send the plastic bottle blank to the mold of the blow molding machine or take the blown molded bottle out of the mould. Translation split type, with templates at both ends and guide rods on both sides, the four sides are like a frame, and the forming mold is inside the frame, so it is generally necessary to change the direction (such as front and rear plus bottom) or one-way movement when...

AI Technical Summary

Problems solved by technology

The applicant has now invented a clamp-type (like steel wire clamp) mold opening and closing mechanism for plastic extrusion and stretch blowing machines. This mechanism makes the mold open like a fan on both sides of the jaw, and the bottle blank can be taken and delivered independently of translation. It is completed by the robot arm. At present, there is no matching pick-up and delivery device, so it cannot achieve automatic production.
