Adjustable blowing head for glass bottle production

Abstract

The invention relates to the technical field of glass production. The invention aims to provide an adjustable blowing head for glass bottle production, which comprises a blowing head body, wherein a groove used for being arranged outside a bottle opening in a sleeving mode is formed in the bottom of the body, a vertical and square center hole is formed in the body, and the center hole extends into the groove from the upper surface of the body; an air blowing pipe is arranged in the center hole, a square sliding head matched with the center hole is arranged at the upper end of the air blowing pipe, a vertical air guide hole is formed in the center of the sliding head, and the air guide hole is communicated with the upper end of the air blowing pipe; and the body is composed of an upper half section and a lower half section, a driving mechanism is arranged in the area between the upper half section and the lower half section, and the air blowing pipe can be driven by the driving mechanism to move in the center hole in the vertical direction. The height of the air blowing pipe can be quickly and accurately adjusted, so that the length of the air blowing pipe extending into a bottle opening of a glass bottle blank is changed, and the production requirements of different types of glass bottles are met.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to an adjustable blowing head for glass bottle production. Background technique [0002] In the process of using the pressure blowing method to produce glass bottles, it is necessary to use self-suction or dripping to add molten glass raw materials into the initial mold, and then use the extrusion mold to process the raw materials into a blank with a bottle mouth, and then the blank It is transferred to the final mold, and the blank is blown by the blowing head. After the blank is inflated, it fills the inner cavity of the final mold, and finally the shape is realized. Since the final molding quality of the glass bottle is closely related to the final molding and the blowing head, it is not difficult to see that the blowing head is the core component in the glass bottle production process. The blowing head generally includes a main body that can be sleeved outside the bottl...

AI Technical Summary

Problems solved by technology

But the existing blowing head mainly has the following problems that need to be improved: 1, the stretching length of the blowing pipe of the existing blowing head in the bottle mouth cannot be adjusted, and for glass bottles with different heights and different material components, it will As a result, parameters such as inflation speed and inflation pressure cannot be optimally adapted, thereby affecting the molding quality of glass bottles; 2. The existing blowing head does not have a heating function, and the temperature of the pressurized air blown directly from the blowing head is relatively low , during the blowing process, the temperature of the blank from the original state to the final state drops too fast, which will lead to poor expansion and filling of the blank, which will also affect the final molding quality of the bottle
