Bottle base conveying device

Abstract

The invention provides a bottle base conveying device. The device comprises a cooling water channel and a chain bracket which are arranged on a heater, wherein the chain bracket is provided with a transmission chain; the transmission chain is provided with a friction wheel; the friction wheel is inserted between plastic bottle bases in operation, and tightly pulls a screw socket of the plastic bottle base on the wall surface of the cooling water channel; the cooling water channel is provided with a groove to be inserted by a convex ring of the screw socket of the plastic bottle base; the height of the groove is matched with that of the convex ring; the friction wheel is connected with a self-transmission drive mechanism. The bottle base conveying device has the advantages of good conveying stability, good durability and good heat dissipation effect.

Description

technical field [0001] The invention relates to a bottle blank conveying device for a plastic bottle blank heater. Background technique [0002] The production of plastic bottles generally adopts a two-step method. First, the plastic raw materials are injected into tubular preforms with an injection molding machine, and then the plastic preforms are heated with a heater, and then the preforms are stretch blown with a stretch blowing machine. At present, most preform heaters insert the preform on the supporting seat, and the supporting seat is arranged on the dragged chain and passes through the infrared heating zone to heat the preform. The disadvantage of this technology is that when it is necessary to load and unload the preform on the support seat, multiple sets of manipulators are needed to cooperate with the stretch blowing mechanism, which not only causes complicated mechanism and high cost, but also has many movements of the manipulator and the relative speed Slow, s...

AI Technical Summary

Problems solved by technology

[0005] Although this method solves the problem of preform positioning, because the screw mouth of the preform has an oblique thread, its rolling posture is not straight, and the preform body will move up and down, which will affect the stability of the preform transportation; in addition, in order to To enhance the friction effect, the friction belt is generally made of rubber. The screw thread of the preform has a strong pulling and scratching effect on the friction, causing the friction belt to be damaged quickly; and due to the friction of the rubber, dust and other substances will easily fall off. Into the production container, affecting the hygiene of the container

Finally, the friction band affects the heat transfer between the screw port and the water channel
