Dual-temperature-control double-loop cooling system of bottle cover compression molding machine

Abstract

The invention discloses a dual-temperature-control double-loop cooling system of a bottle cover compression molding machine. The dual-temperature-control double-loop cooling system comprises an upper mould and a lower mould of the bottle cover compression molding machine; the upper mould and the lower mould are separately equipped with cooling loops; the upper mould cooling loop comprises an upper mould cooling water hole formed in an upper mould guide rod of the upper mould; the upper mould cooling water hole is connected with an upper mould cold water joint; the upper mould cold water joint is connected with an upper mould water-distributing plate through an upper mould cold water tube; the upper mould water-distributing plate is connected with an upper mould transmission main shaft through an upper mould water-distributing tube; an upper mould water path is arranged in the upper mould transmission main shaft; the upper mould water path is connected with an upper mould water rotary joint; the upper mould water rotary joint is connected with an upper mould water cooler; the lower mould cooling loop comprises a lower mould cooling water hole formed in a lower mould guide rod of the lower mould; the lower mould cooling water hole is connected with a lower mould water-distributing plate through a lower mould water-distributing tube; the lower mould water-distributing plate is connected with a lower mould transmission main shaft; a lower mould water path is arranged in the lower mould transmission main shaft; the lower mould water path is connected with a lower mould water rotary joint; and the lower mould water rotary joint is connected with a lower mould water cooler.

Description

Technical field [0001] The invention relates to a dual-temperature-control dual-circuit cooling system of a bottle cap molding machine, which belongs to the field of plastic machinery. Background technique [0002] The existing bottle cap molding machine cooling system uses a chiller to cool the upper mold and the lower mold of the bottle cap at the same time. The performance is the same flow, the same water temperature, and the same pressure, so the wall thickness and requirements are different. The bottle cap cannot be adjusted. If the water is too cold, it will cause serious condensation on the machine and the mold. It is easy to rust and oxidize the machine itself. It will have a serious impact on the service life of the machine and the hygiene and safety of the cap. The surface watermark is too large, which affects the aesthetics of the product appearance. However, if the water temperature is high, the screw teeth of the bottle cap will be pulled, and it will not be easy to...

AI Technical Summary

Problems solved by technology

[0002] The existing bottle cap molding machine cooling system uses a chiller to cool the upper mold and the lower mold of the bottle cap at the same time, which means that the same flow rate, the same water temperature, and the same pressure work, so that the wall thickness and requirements are different. The bottle cap cannot be adjusted. If the water is too cold, the machine and the mold will have serious condensation, which will easily rust and oxidize the machine itself, which will have a serious impact on the service life of the machine and the hygiene and safety of the bottle cap. The surface watermark is too large, which affects the appearance of the product

However, if the water temperature is high, there will be phenomena such as pulling the screw teeth of the bottle cap, making it difficult to demould, etc., resulting in defective products.
