TECHNICAL FIELD
[0001] The utility model relates to a powdering machine technical field, specifically for a powdering machine's unloading device. BACKGROUND
[0002] The powdering machine is a key equipment for efficiently refining raw materials into powder, and a powder outlet is designed below the core component - the crushing mechanism, so as to smoothly guide the finished fine powder out. In the current powder collection process, cloth bags equipped with tightening ropes are widely used. Although this design is good in portability and sealing, it faces some challenges in actual operation, as follows:
[0003] 1. Cloth bag falling off: During the operation of the powdering machine, especially in high-yield and fast powder flow conditions, the bag opening of the cloth bag is prone to fall off from the edge of the powder outlet, causing powder scattering, affecting the working environment and possibly causing raw material waste.
[0004] 2. Complicated operation: When collecting powder, the user needs to manually put the bag opening on the powder outlet and tighten the tightening rope, which is a relatively complicated operation.
[0005] The main reasons for the above problems are:
[0006] 1. Smoothness of the stainless steel shell: The stainless steel material used for the shell of the powdering machine has a smooth surface, and the friction coefficient between the cloth bag material is low, making it difficult to form a stable connection, especially under the impact of powder flow, which is more prone to falling off.
[0007] 2. Design limitations of the cloth bag: Although the cloth bag is convenient to carry and seal, its fixed method relying on the tightening rope is not stable enough in high-speed and high-volume powder flow environments, and cannot effectively resist external forces.
[0008] Therefore, we propose a powdering machine unloading device. INVENTION CONTENTS
