Tablet press and feeding detection device and ventilation device thereof

Abstract

The invention belongs to the technical field of tablet presses, in particular to a tablet press and a feeding detection device and ventilation device thereof. A ventilation opening is formed in the tablet press, an airflow driving function of a dust remover is utilized, airflow in a driving cabin and airflow in a lower cabin of the tablet press are driven to flow, good heat dissipation and ventilation in the tablet press are achieved, heat accumulation in the tablet press is reduced, and the probability that parts of the tablet press are damaged or defective products are produced due to the high temperature is reduced; and a temperature switch, a lower cabin air outlet door linked with the temperature switch, and a lower cabin air inlet door which can be opened and closed as required arearranged, so that the lower cabin can be internally ventilated and cooled only when the temperature is too high, and the lower cabin air inlet door and the lower cabin air outlet door are closed whenthe temperature is not too high, so that the internal environment of the lower cabin is kept clean to the greatest extent. According to the feeding detection device, a proximity switch is arranged ina discharging pipeline, and an alarm is linked to identify and raise alarm against an insufficient state of the materials, so that the yield is improved.

Description

technical field [0001] The invention belongs to the technical field of tablet presses, and in particular relates to a feeding detection device, a ventilation device and a tablet press of a tablet press. Background technique [0002] The tablet press machine is mainly used in the tablet process of the pharmaceutical industry. It is an important equipment for pressing granules into tablets in industrial production. In the common tablet press, the driving cabin itself has two cooling fans with a power of 15 watts, and the heat dissipation efficiency is low; Usually, in order to keep the interior clean, there are no ventilation channels, so the heat cannot be dissipated. Usually in the production workshop, the tablet press machine is placed in the tablet pressing room, which is a clean area, and the production workshop is also equipped with a non-clean area isolated from the clean area. A dust collector is installed in the non-clean area, and the dust collector passes through t...

Problems solved by technology

[0005] At present, during this process, a hopper window is installed on the hopper to observe whether the material in the hopper is supplied sufficiently. Sensitive to air humidity or poor fluidity, it is easy to cause the window of the hopper to be blocked by powder, and it is impossible to observe whether the supply is insufficient in time, and because the material is sensitive to air humidity or poor fluidity, it is easy to form accumulation at the outlet of the hopper, resulting in forced feeder Insufficient supply of materials, high defective rate
