Positive blowing mechanism of bottle making row machine

Abstract

The invention discloses a positive blowing mechanism of a bottle making row machine. The blowing mechanism is characterized in that a hollow channel is formed in the middle of a blowing head body of a blowing head; a blowing tube is provided; the top of the blowing tube is fixed at the bottom of an air distribution valve in a threaded connection manner; the lower part of the blowing tube penetrates through the hollow channel of the blowing head and reaches the opening of a glass bottle; an annular air exhaust side way is formed between the outer side wall of the blowing tube and the inner wall of the hollow channel; positive blown air enters the positive blowing channel, passes through an inlet channel of a valve core, passes through the air distribution valve and enters the blowing tube to form a blowing channel; the annular air exhaust side way is communicated with exhaust holes through an outlet channel of the valve core so as to form an exhaust channel. The blowing mechanism can sufficiently utilize positive blown air to accomplish blowing of the glass bottle, can avoid energy waste and is beneficial for cooling and heat radiation of the glass bottle.

Description

technical field [0001] The invention relates to a mold used in the production of glass products (bottles and cans), in particular to a positive blowing mechanism of a bottle-making row machine. Background technique [0002] When producing glass bottles and cans, whether it is blow-blow method or press-blow method, the rank-and-row machine bottle-making machine must involve the process of blowing air, and the air consumption of this process basically accounts for the entire bottle-making process. 30%-40% of that, therefore, reducing the air consumption of positive blowing is conducive to energy saving and consumption reduction. [0003] Glass bottles and jars are divided into two processes in the production process: forming and shaping. The molding process refers to the process in which the glass blank is turned from the initial mold to the forming mold, and then the glass material is blown by positive blowing to make the glass material cling to the inner wall of the forming...

AI Technical Summary

Problems solved by technology

Based on the blowing principle, it can be seen that the part of the blowing air discharged from the vent hole 4 only plays a role in balancing the pressure, and does not take away any heat in the glass bottle, and also causes a large waste of compressed gas.
