[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Referring to Figure 1 - Figure 3 In an embodiment provided by the present utility model: a threaded multi-wedge head drum includes a rotating shaft 1, and the material of the rotating shaft 1 is stainless steel, which can provide excellent corrosion resistance and strength to ensure the stability and durability of the rotating shaft 1 during long-term use. It is characterized in that: a drum body 2 is installed outside the rotating shaft 1, and the material of the drum body 2 is cast iron, which not only has good cost-effectiveness but also can withstand relatively high loads. External threads 3 are provided on the outside of the drum body 2, and the external threads 3 are evenly distributed on the outside of the rotating shaft 1. The external threads 3 are evenly distributed along the outside of the rotating shaft 1, which is beneficial to increasing the friction between the drum body 2 and the material and improving the transmission efficiency. Multi-wedge pulleys 4 are fixedly connected to both the left and right sides of the drum body 2, and the material of the multi-wedge pulleys 4 is a high-performance synthetic resin, which provides good wear resistance and elasticity to ensure the long-term durability of the pulley under high-speed operation and high-load conditions. A plurality of spiral bodies 5 are detachably connected to the outside of the two multi-wedge pulleys 4, and the inclination angle of the spiral body 5 with respect to the axis of the rotating shaft 1 forms an angle α of 75° to 105°, which is beneficial to adjusting the axial movement speed of the material in different application scenarios. The spiral bodies 5 on the outside of the multi-wedge pulley 4 are evenly distributed horizontally;
[0032] Referring to Figure 2 - Figure 4, installation chutes 6 are provided inside both of the two multi-wedge belt pulleys 4. The design of the installation chutes 6 here can ensure the smooth installation of this roller. The outer part of the rotating shaft 1 is arranged inside the installation chutes 6. Positioning grooves 7 are provided inside both of the two multi-wedge belt pulleys 4. On both the left and right sides of the outer part of the rotating shaft 1, a plurality of positioning blocks 8 are fixedly connected. The outer parts of the positioning blocks 8 are arranged inside the positioning grooves 7. The design here can achieve the quick docking and installation of the multi-wedge belt pulley 4 through the mutual cooperation of the positioning blocks 8 and the positioning grooves 7. Wear-resistant components are provided on the outer parts of both the rotating shaft 1 and the spiral body 5. The wear-resistant component includes a first wear-resistant coating 9, and the material of the first wear-resistant coating 9 is a tungsten carbide coating. The tungsten carbide coating provides extremely high hardness and wear resistance. The inner part of the first wear-resistant coating 9 is fixedly connected to the outer part of the roller body 2. A second wear-resistant coating 10 is fixedly connected to the outer parts of a plurality of spiral bodies 5. The material of the second wear-resistant coating 10 is a ceramic coating. The ceramic coating not only has high hardness but also excellent thermal stability and chemical stability, thereby protecting the service life of the spiral body 5 in a harsh environment.
[0033] Working principle: First, the roller body 2 is made of cast iron, which has good load-bearing capacity and cost-effectiveness. The external threads 3 provided on its outer part are evenly distributed. Such a design can significantly increase the contact area and friction force between the roller body 2 and the material, thereby improving the transmission efficiency and stability. When the material is placed on the roller, the external threads 3 can effectively grip the surface of the material to prevent sliding and ensure that the material can move smoothly along the predetermined direction. Secondly, the multi-wedge belt pulleys 4 fixedly connected to both the left and right sides of the roller body 2 are made of high-performance synthetic resin material. This material not only provides the necessary wear resistance but also maintains good elasticity, enabling the belt pulley to still have a long service life under high-load and high-speed operating conditions. The design of the multi-wedge belt pulley 4 allows a plurality of spiral bodies 5 to be detachably connected to its outer part. The inclination angle of each spiral body 5 forms an angle of 75° to 105° with the axis of the rotating shaft 1. This can adjust the axial movement speed of the material by changing the angle of the spiral body 5 to adapt to different conveying requirements. In addition, the design of the roller also takes into account easy installation and positioning accuracy. The installation chutes 6 and the positioning grooves 7 provided inside the multi-wedge belt pulley 4 cooperate with the plurality of positioning blocks 8 on the rotating shaft 1. This design not only simplifies the installation process but also ensures the precise docking between the belt pulley and the roller body 2, avoiding deviation during operation. Finally, to further improve the durability of the equipment, wear-resistant components are provided on the outer parts of both the rotating shaft 1 and the spiral body 5, including the first wear-resistant coating 9 with a tungsten carbide coating and the second wear-resistant coating 10 with a ceramic coating. These high-quality coating materials can significantly improve the wear resistance of the components and extend the service life of the equipment in a harsh environment.
[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
