This process is a key step in the manufacture of lead-free glass products and involves heating the raw materials (usually composed of compounds such as silicates and oxides) to a high enough temperature to transform them from solid to liquid.
[0003] When personnel melt the lead-free glass shell raw materials, the traditional melting is to add the raw materials into the melting device, which lacks an effective stirring mechanism and has an unsatisfactory stirring effect. As a result, the raw materials cannot be fully mixed during the melting process, resulting in uneven melting, low melting efficiency, and uneven melting. As a result, the melting efficiency of the lead-free glass shell raw materials is low, and the product quality cannot be guaranteed. In addition, adding power sources for multiple stirring will lead to waste of resources and increase the energy consumption of the device. Utility Model Content

The person starts the motor 5, and the internal heating system of the melting furnace 1 starts to work, heating the raw materials to gradually melt them into liquid glass. The motor 5 drives the pulley 1 6 to rotate, and the pulley 2 7 is driven by the belt to rotate synchronously. The pulley 2 7 drives the round rod 16 and the stirring block 14 thereon to rotate, so as to stir the raw materials in the melting furnace 1 to promote uniform mixing and melting of the raw materials. The pulley 1 6 drives The reciprocating screw 12 rotates, and since the circular scraper 15 is sleeved with the reciprocating screw 12 through a thread, the circular scraper 15 reciprocates on the reciprocating screw 12, and the outer surface of the circular scraper 15 moves on the inner wall of the melting furnace 1, so that the raw materials on the inner wall of the melting furnace 1 and the raw materials inside the melting furnace 1 are fully mixed and melted, and the spoiler wave plate 17 inside the circular scraper 15 moves up and down inside the melting furnace 1, which complements the rotation and movement of the stirring block 14, further enhancing the stirring effect, breaking the temperature stratification and bubbles in the molten liquid, and improving the stirring effect.

The setting of the motor 5 gives the pulley 6 the power to rotate. The symmetrical setting of the reciprocating screw 12 and the long rod 13 makes the annular scraper 15 more stable during displacement. The staggered setting of the spoiler wave plate 17 makes the liquid disturbed in the up and down directions during the flow process, and further fully mixed. The outer surface of the annular scraper 15 moves on the inner wall of the melting furnace 1, and the raw materials on the inner wall of the melting furnace 1 are fully mixed with the raw materials inside the melting furnace 1 for melting.
