Full-automatic slide pitch-changing manipulator of bottle blowing machine

Abstract

The invention provides a full-automatic slide pitch-changing manipulator of a bottle blowing machine, comprising a base plate, wherein the base plate is provided with a fixing base; a fixing plate is provided with a rotating air cylinder; the rotating air cylinder is connected with a sliding shaft; the sliding shaft is provided with a movable block; the movable block is provided with pipe billet fingers; and the pipe billet fingers are driven by a finger air cylinder. The full-automatic slide pitch -changing manipulator is characterized in that: the base plate is slidably provided with the movable plate; the movable plate is provided with racks; the sliding shaft is provided with gears; the gears are engaged with the racks; the movable plate is manufactured with a pitch-changing slide; rolling wheels are arranged below the movable block; and the rolling wheels are fitted with the pitch-changing slide. By the technical scheme in the invention, the gears and the racks are engaged and turned, and the slide has a changed pitch, so that the bottle billets tightly arranged in a heater are accurately arranged on bottle billet supporting bases which are arranged widely in a pull-blow machine through the pitch-changing manipulator; and the slide pitch-changing manipulator is simple in structure, stable and reliable in action.

Description

technical field [0001] The invention relates to a slideway variable distance manipulator of a fully automatic bottle blowing machine, which belongs to the field of plastic machinery. Background technique [0002] Using a plastic blow molding machine to produce hollow plastic containers, such as mineral water bottles, oil bottles, etc., first use an injection molding machine to inject plastic raw materials into preforms, and the preforms are heated twice by a heater, and then the heated bottles are blown by a stretch blowing machine. Embryo stretch blow molding. The existing equipment is that the heater (oven) and the blow molding machine share the same chain running track (called a linear blow molding machine), and the distance between the heating seat (preform support seat) on the chain is determined by the size of the container (bottle) after stretch blowing. It is determined that the spacing is larger, and the heat utilization rate of the heater is relatively low. Especi...

AI Technical Summary

Problems solved by technology

The existing equipment is that the heater (oven) and the blow molding machine share the same chain running track (called a linear blow molding machine), and the distance between the heating seat (preform support seat) on the chain is determined by the size of the container (bottle) after stretch blowing. Therefore, the spacing is larger, and the heat utilization rate of the heater is relatively low. Especially when producing large-capacity bottles, the spacing of the heating seats is larger, the heat utilization rate of the heater is lower, and the energy consumption of the machine is increased.
