Preparation devices for medium borosilicate medicinal glass tubes and methods thereof

A preparation device for a medium borosilicate medicinal glass tube, comprising:

• a melting system, wherein the melting system includes a melting zone and a clarification zone disposed in sequence;
• the melting zone is configured to melt batch material into molten glass and feed the molten glass into the clarification zone, and the clarification zone is configured to perform bubble homogenization and stirring deaeration on the molten glass, and feed the molten glass into a feeder of a forming system through a feed pipe;
• the forming system, wherein the forming system includes a muffle furnace, a shaping furnace, and an annealing furnace arranged in sequence;
• wherein the muffle furnace includes the feeder, the feeder is in a shape of an inverted truncated cone, a guide pipe is arranged below the feeder, the guide pipe extends to a lower end of the shaping furnace from the muffle furnace, a furnace channel is disposed outside the feeder and the guide pipe inside the muffle furnace, the furnace channel is coaxially with the feeder and the guide pipe to form an annular seam;
• at least one set of traction rollers and at least one guide clamping ring are provided in the shaping furnace, the at least one set of traction rollers and the at least one guide clamping ring are configured to clamp and position glass melt, and the at least one set of traction rollers are arranged on a gripping drive bracket, the gripping drive bracket and the at least one guide clamping ring are arranged on a wall of the shaping furnace and connected to an external servo motor;
• and at least one set of traction rollers and at least one guide clamping ring are provided on an upper part of the annealing furnace;
• and
• a cutting system that cuts a formed and annealed glass tube according to a preset size, wherein the cutting system is disposed below the forming system, wherein
• a side of each of the at least one set of traction rollers is a rotational surface, a plurality of traction rollers are one set of traction rollers which are set at a same horizontal level in the shaping furnace, and generatrices of the rotational surfaces of the traction rollers form an annulus wrapping the glass tube.
