AI Technical Summary

Technical Problem

The existing glass blowing process is labor-intensive and has low production efficiency. Unstable manual rotation leads to irregular shaping of the liquid glass, affecting the quality of the finished product.

Method used

The system employs an air blowing device, a preliminary shaping device, a pre-forming device, and a rotating mechanism. A micro motor drives the rotating mechanism to rotate the metal air tube. Combined with the pin positioning component and the air blowing device, the system achieves automated shaping and forming of molten glass.

Benefits of technology

It reduces labor intensity, improves production efficiency and forming quality, ensures uniform stress on all parts of the molten glass, overcomes the influence of gravity, and guarantees the roundness and quality of the blown glass.

Abstract

This invention discloses a blowing device and method for insulated double-layered glassware, belonging to the technical field of glassware manufacturing equipment. It includes a blowing device, a preliminary shaping device, a pre-forming device, and a rotating mechanism. The pre-forming device is installed on the side of the preliminary shaping device, and the rotating mechanism is assembled at the rear end of the blowing device. The blowing device is mounted on the preliminary shaping device and the pre-forming device. The blowing device and method of this invention use a micro-motor for power, significantly reducing labor intensity and improving shaping efficiency compared to manual rotation. Drilling a hole in the molten glass provides a breakthrough point for blowing the glass. The use of a power device for rotation and blowing replaces manual operation, allowing the operator to focus on observing the forming state of the molten glass and adjusting the blowing volume, rotation speed, and angle based on the real-time forming status, thus improving the quality of the blown glass.
