Description

Technical Field

[0001] The utility model relates to the technical field of high borosilicate glass pressing, in particular to an automatic bottom-sealing and plastic-forming device for high borosilicate glass tubes. Background Art

[0002] At present, there are mainly two methods for manufacturing single-layer glass cups. One is the kiln production method, that is, through the method of pressing or blowing molds, using the stamping of a punch or the pressure of air pressure to force the high-temperature glass liquid to form in the mold. When producing glass cups by this manufacturing method, a kiln needs to be equipped, and the requirements for related equipment are relatively high. Moreover, this method has problems such as low production efficiency, high processing cost per cup, poor transparency of the finished product, and high requirements for the supporting facilities of the production environment. The other is the cutting production method. First, a glass tube is made. Using the glass tube as raw material, the two ends of the glass tube are clamped and supported and rotated synchronously. The glass tube is locally heated with a flame until the glass softens. Then, a blade made of a heat-resistant material with a thickness less than the width of the heating area and not affinity with the glass is slowly cut from the middle of the heating area, so that a glass tube gradually forms a glass cup with a bottom.

[0003] However, in the existing technology, when sealing the bottom of the glass tube, most rely on a hand-held flame spraying device to heat the continuously rotating glass tube and cut it manually. The splitting effect of the glass tube is not ideal, and the shape of the bottom end of the glass tube is prone to be irregular, affecting the effect of the processing work, thereby affecting the product quality of the glass cup prepared from the glass tube.

[0004] The information disclosed in this background art section is only intended to enhance the understanding of the overall background of the utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.
