摘要：【中文】本发明属于压片机技术领域，尤其涉及一种压片机的进料检测装置、通风装置和压片机，通过在压片机上设置通风口，利用了除尘器的带动气流功能，带动驱动舱和压片舱下舱内的气流流动实现了压片机内的良好散热通风，降低了压片机内的热量积累，减小了压片机因为高温导致的零部件损坏或者生产不良品的概率；设置温度开关，以及与其相联动的下舱出风门，和可根据需要开闭的下舱进风门，使得压片舱下舱只有温度过高时才会利用除尘器进行内部通风散热，在不通风时，下舱进风门和下舱出风门均关闭，最大可能的保持压片舱下舱内部的环境清洁。进料检测装置，通过在出料管道处设置接近开关，并联动有报警器对物料不足状态进行识别报警，提高了良品率。 【EN】The invention belongs to the technical field of tablet presses, and particularly relates to a feeding detection device, a ventilation device and a tablet press of the tablet press.A vent is arranged on the tablet press, and the airflow function of a dust remover is utilized to drive airflow in a driving cabin and a lower cabin of a tablet pressing cabin to flow, so that good heat dissipation and ventilation in the tablet press are realized, the heat accumulation in the tablet press is reduced, and the probability of damage to parts or defective product production of the tablet press caused by high temperature is reduced; the temperature switch is arranged, the lower cabin air outlet door is linked with the temperature switch, and the lower cabin air inlet door can be opened and closed according to needs, so that the inner ventilation and heat dissipation can be carried out by using the dust remover only when the temperature of the lower cabin of the tabletting cabin is too high, the lower cabin air inlet door and the lower cabin air outlet door are both closed when the air is not ventilated, and the inside environment of the lower cabin of the tabletting cabin is kept clean to the greatest extent. Feeding detection device through set up proximity switch in ejection of compact pipeline department to the linkage has the alarm to discern the warning to the not enough state of material, has improved the yields.
