Description

Technical Field

[0001] The utility model belongs to the technical field of quartz tube production equipment, in particular to a tube drawing device for quartz tube production. Background Art

[0002] Quartz tubes are a special type of industrial glass made from silicon dioxide and are an excellent base material. Quartz glass possesses a range of excellent physical and chemical properties. It is used in electric fire buckets, electric stoves, and electric heaters to generate heat. Quartz tubes are categorized into various types based on their properties and applications, including transparent quartz tubes, UV-filtering quartz tubes, and colored quartz tubes. Each type of quartz tube has distinct characteristics in terms of light transmittance, corrosion resistance, and high-temperature resistance.

[0003] According to the patent authorization publication number CN218202532U, a tube drawing machine for producing quartz tubes for photovoltaic semiconductors includes a base, a water reservoir, a collection frame, a support plate and a heater. The top left side of the base is connected to the water reservoir, the top right side of the base is slidably connected to the collection frame, a support plate is connected between the base and the water reservoir, and a heater is installed on the top left side of the support plate. By starting the water pump, the water pump will draw water into the nozzle, and the water will then be sprayed onto the shaping tube through the nozzle. The water will take away the heat of the quartz tube in the shaping tube, allowing the quartz tube to cool and shape. In this way, the recycled water can be cooled to achieve the effect of cooling the quartz tube, avoiding the quartz tube from cooling and not shaping.

[0004] However, it has many disadvantages. For example, when water is sprayed directly on the shaping tube, the cooling effect is limited due to the thickness of the wall of the shaping tube. At the same time, in actual production, the quartz tube coming out of the shaping tube is not cooled to room temperature, but still has a certain temperature and needs to be cooled further. Moreover, in the above patent, after the quartz tube is cut off, it falls directly into the collection frame, which has the risk of being broken. Utility Model Content
