Raw material crushing and recycling device for hard capsule production Technical Field The invention relates to the technical field of capsule production, in particular to a raw material crushing and recycling device for hard capsule production. Background In the hard capsule production process, raw materials such as gelatin, additives and the like are often required to be crushed to achieve the required particle fineness and mixing uniformity. Traditional raw material crushing processes are generally carried out step by adopting independent cutting (coarse crushing) equipment and crushing (fine crushing) equipment, materials need to be subjected to processes of transferring, intermediate collecting and the like, so that the production efficiency is low, dust and raw materials are easy to fall off in the transferring process, and waste and environmental pollution are caused. Some prior comminuting devices have attempted to combine cutting and comminuting functions, but have had the following problems: The crushing uniformity is insufficient, namely, the cut material directly enters a crushing area, and partial larger particles enter a crushing link without being fully cut due to uneven material mobility, so that the final crushing granularity is uneven, and the quality of the subsequent capsule molding is affected. The separation and recovery efficiency of the qualified powder is low, in the crushing process, the powder meeting the fineness requirement is mixed with particles which are not up to standard, and uniform screening is usually carried out after the whole batch is crushed, so that the production period is prolonged, and the instant and continuous recovery of the qualified powder cannot be realized. The structure is loose, the energy consumption is higher, the cutting and crushing mechanism is often controlled by an independent driving unit, the transmission structure is complex, the occupied space is large, the synergy is poor, and the whole energy consumption is higher. The materials are easy to be blocked, in the crushing process, fibrous or viscous materials are easy to be wound on a blade or blocked at a screen, frequent shutdown and cleaning are required, and the production continuity is affected. Therefore, there is an urgent need to design an integrated device which can realize continuous, efficient and uniform crushing, has an instant grading recovery function, has a compact structure and operates cooperatively, so as to solve the defects in the prior art.
