Problems solved by technology

This technical solution has the following disadvantages: the self-rotating chain meshes with the sprockets of all the preform seats, the stability is poor during operation, and the noise is large
This requires multiple self-rotating chains to drive the preform holders in different rows, and the preform holders in the same row must be connected by the same node of the conveyor chain, so the transmission structure will be very complicated.

Embodiment Construction

[0015] The structure of an embodiment of the bottle blank rotation device of the blow molding bottle blank heating system of the present invention, as Figure 1-3 shown. The preform rotation device of the blow molding preform heating system is integrally installed on a frame. The frame is located below the preform heating zone. A driving sprocket 4 and a driven sprocket 4' are respectively installed at the two ends of the frame rear side. The driving sprocket 4 is driven by a stepping motor. A conveyor chain 8 is connected between the driving sprocket 4 and the driven sprocket 4'. Each group of outer chain plates of the conveying chain 8 is fixedly connected with the rear end of an aluminum strip flat plate 1 . There is a horizontal guide rail at the upper end of the frame front side, which corresponds to the horizontal section on the conveyor chain 8 and accommodates the guide wheels 15 at the front ends of each bar-shaped flat plate 1 . In this way, the strip-shaped fla...

Abstract

A bottle blank rotating apparatus for the heating system of blowing bottle blanks is composed of a plane plate, multiple bottle blank holders installed on said plate in rotary mode, multiple magnets installed eccentrically to said bottle blank holders (one for one), and an active plate with multiple magnets relative to the magnets on bottle blank holders. When said active plate and plane plate is parallelly swinging along a circular tracing, the bottle blank holders and their bottle blanks are rotating under the action of magnetic attraction.

Description

technical field [0001] The invention relates to a plastic processing equipment, in particular to an equipment combined with blow molding and parison manufacturing. technical background [0002] In the preform heating system of the two-step blown synthetic resin bottle, in order to ensure that the preform is heated evenly, the usual practice is to make the preform seat on which the preform is placed to rotate, so as to drive the preform to rotate and receive heat during the heating process. radiation. Chinese Invention Patent Specification CN 1067006C discloses the patent No. ZL 95120815.2, and in the technical proposal titled "Blow Molding Device and Forming Method", several preform holders for preforms are respectively installed on a conveying chain, and the conveying The chain transports the preform holders where the preforms are placed through the heating zone; each preform holder is equipped with a sprocket, and another rotation chain meshes with the sprockets of all th...
