AI Technical Summary

Technical Problem

Traditional cosmetic bottle production suffers from problems such as low efficiency in material feeding and distribution, unstable conveying, easy product damage, high defect rate, high manual labor, and high production costs, making it difficult to meet market demands and meet the company's goals of cost reduction and efficiency improvement.

Method used

The preforms are precisely positioned and stably transported by a drive motor that drives a lead screw. Combined with the clamping of the slide table, fixture seat and fixture head, the conveying process is stable. The material distribution mechanism is designed with a semi-circular grooved material distribution plate, which, together with the rotating column and guide plate, achieves accurate material distribution and reduces accumulation and omission. The various processes are closely connected to achieve automated operation.

Benefits of technology

It improved the efficiency and quality of cosmetic bottle production, reduced product damage and defect rates, reduced manual labor and production costs, and met market demands and the company's goal of cost reduction and efficiency improvement.

Abstract

This utility model discloses a fully automated blow molding device for cosmetic bottles, including a frame, a feeding robot, a conveying mechanism, a dispensing mechanism, a heating mechanism, and a blow molding mechanism. The frame provides overall support, and the feeding robot automatically picks up PET preforms and places them on the conveying mechanism. The conveying mechanism uses a drive motor and lead screw to drive a slide table, and combines a cylinder, a pull rod, and a clamping head to achieve stable transmission of the preforms. The dispensing mechanism uses a rotating column to drive a dispensing plate, and completes precise dispensing of the preforms through its outer edge groove and guide plate. After dispensing, the preforms enter the heating mechanism, where a sprocket transmission system drives uniform heating to reach the softening temperature for blow molding. They are then transferred to the blow molding mechanism, where they are inflated with compressed air, held under pressure, and cooled to complete the molding process. This device achieves automated production through the coordinated operation of its various mechanisms, effectively improving production efficiency, reducing defect rates and production costs, and has good application and promotion value.
