Description

Glass tube bubble blowing molding machine and molding process

Technical Field

The invention relates to the technical field of glass tube bubble blowing and forming, in particular to a glass tube bubble blowing and forming machine and a forming process.

Background Art

At present, glass tube bubble blowing machines are widely used in the manufacture of various glass products, such as glass bottles, glass cups, etc. Traditional glass tube bubble blowing machines are usually composed of a primary mold mechanism and a conveying and cooling mechanism. The primary mold mechanism is generally composed of a rotating mechanism, a disc, a heating and flame-spraying mechanism, a blowing mechanism and a bubble shell forming mold. The glass tube is blown into a product and the glass is burned through the flame head; the primary mold mechanism is used to heat and soften the glass tube, and blow it into the desired shape through air pressure, and then solidify it into a glass product through natural solidification. However, it is transported away by the conveying and cooling mechanism; there are some problems with the traditional glass tube blowing and foaming machine. First, the operator needs to manually take the blown glass products out of the primary molding mechanism. Since only one blowing and molding is performed, the molding effect is not good and the product is irregular. In order to improve the molding effect, it is necessary to continue to put a product into the blowing mechanism for finalization, and then take out the product and package it. Manual operation is required during the transportation process, and the degree of dependence on manual labor is high. This manual operation method is not only time-consuming and labor-intensive, but also seriously affects the production efficiency of the enterprise, and is also easy to cause damage to the glass products and reduce the quality of the products produced; secondly, due to the temperature and shape during the blowing process Changes, the size and quality control of glass products are more difficult; Chinese patent application No. 202211212010.2 discloses a cake-pressed bubble blowing machine and a product blowing process, the cake-pressed bubble blowing machine and the special-shaped glass product blowing process, by extending the first telescopic rod, the bubble blowing air pipe, the pressure plate, the transmission chain, the sprocket, and the connecting block, so that the block rotates, and the block drives the internal glass raw material to rotate, so that the glass raw material is evenly blown, and the efficiency of blowing the glass raw material is improved. The bubble blowing machine is an existing conventional mechanism, which mainly solves the problems of heating the glass raw material and blowing the glass raw material evenly. It only performs one initial forming, and the subsequent processes require manual operation, and there are the technical problems mentioned above.

Chinese patent application No. 201510189641.0 discloses a spiral tube bubble blowing machine for energy-saving lamps and a bubble blowing process thereof, which includes a frame and a transmission mechanism.

A turntable is provided at the center of the frame, and twelve workstations are provided on the turntable. When blowing air to the tube pins, the blowing time is controlled by an electric cam, and the blowing size is detected by a laser and controlled by an electromagnetic valve. The blowing process in the bubble blowing machine is detected and monitored in real time. The formed product falls on a conveyor belt, is manually clamped, and is placed in a finished product box. The public document also only blows the glass tube once, and the forming effect cannot be guaranteed; it cannot meet the needs in actual use, and therefore a glass tube bubble blowing molding machine and a molding process are proposed.
