Spiral Dragon ConveyerThe Spiral Dragon Conveyer was also known as the Spiral Conveyer. Its working principle was that the rotating spiral blades moved the materials and transported them.
In terms of structure, it has the advantages of simple structure, low manufacturing cost, strong sealing, safe and convenient operation, and more loading and unloading in the middle. Usually, it was composed of the main body of the screw conveyor (including the head section, the middle section, and the tail section), the access device, and the driving device. The spiral shaft has spiral blades, and the surface of the blades can be divided into solid surface type, belt surface type, blade surface type, etc. according to the different materials being transported. The end of the spiral shaft in the direction of material movement is equipped with a thrust bearing to bear the reaction force of the material to the spiral. When the length of the machine is long, a middle suspension bearing should be added. The bearing types at both ends are different. The thrust bearing in the direction of material movement is used to bear the force in the direction of material movement, and the starting end is a centrifugal bearing.
In terms of application, it is widely used in building materials, chemical industry, electric power, metals, coal, grain and other industries. It is suitable for horizontal or inclined transportation of powder, granules and small block materials, such as coal, ash, slag, cement, grain, etc. The material temperature must be less than 200 ° C. It is not suitable for transportation of materials that are easy to deteriorate, sticky, and easy to agglomerate.
In the aspect of forming spiral blades, there were single-piece manual hot pressing forming method, mold hot pressing forming method, mold cold pressing forming method, etc. Different methods had their own characteristics and were suitable for different production scale and blank thickness.
There are various forms of transportation, including horizontal transportation, inclined transportation, vertical transportation, etc. The transportation distance varies according to the shape of the machine, generally from 2 meters to 70 meters, which is reflected in the concrete mixing plant. And the spiral dragon conveyor produced by different manufacturers will have different specifications and characteristics in terms of size and applicable materials. For example, the LS spiral conveyor produced by some manufacturers is generally between 200 - 600mm in diameter and 2 - 30m in length.

Mini Spiral EnchanterSpiral Engraving Machine, also known as LS Spiral Conveyer, was designed and manufactured in accordance with the standard of J B/T679 - 95 Spiral Conveyer. It was the replacement product of GX Spiral Conveyer. It is equipped with an axially-moving journal bearing to compensate for the length error of the screw shaft and adapt to temperature changes. It has the advantages of compact structure, small cross-section area, light weight, good sealing performance, and high transmission efficiency. The middle section and the tail section were installed with bearings to support the spiral shaft, and the head section was used to bear the axial-direction force, which made the process layout flexible and easy to install, disassemble, and move. The spiral screw made of stainless steel was not easy to corrode, including resistance to corrosion, rust, or wear. Its common transportation form is horizontal or inclined transportation. There is a feed valve at the lower end of the feed port. The spiral can be reversed for discharge, which is convenient for discharge and cleaning. It also has acid resistance, alkali-resistance, high and low temperature resistance and other characteristics. Although he did not find any special information about the small spiral entwined dragon, these basic characteristics were also applicable to it. In terms of production, it could be drawn through Solidworks, such as drawing a circle on the top view base plane, stretching, creating a base plane and drawing a circle to generate a spiral line, creating a 3D sketch to convert the spiral line into a solid line, and then using the lofting and bending command to generate the twisted dragon surface.
