Dry powder filling gradual detection device and method

Abstract

The invention discloses a dry powder filling gradual detection device and method. The dry powder filling gradual detection device comprises a rotary base, a filling mechanism, a powder weighing mechanism, multiple groups of supporting and detecting assemblies and a control device, wherein the filling mechanism comprises a supporting rod, a first servo motor and the like; the supporting rod penetrates through a rotating disc and is fixedly connected to a support base, a stator of the first servo motor is fixedly connected to the upper end of the supporting rod, a rotor of the first servo motor is coaxially and fixedly connected to a worm, the worm is sleeved with a charging barrel, and the head end of the charging barrel is fixedly connected to the stator of the first servo motor; the tail end of the charging barrel is rotatably connected to the worm; a feeding bin and a discharging bin are arranged at the upper end and the lower end of the charging barrel respectively, a storage bin is slidably connected to the lower end of the discharging bin, a rack is fixedly connected to the side wall of the storage bin, a second servo motor is fixedly connected to the side wall of the discharging bin, a rotor of the second servo motor is meshed with the rack through a gear, and a powder weighing mechanism is hinged to an opening in the lower end of the storage bin. Through cooperation of the rotating base and the multiple groups of supporting and detecting assemblies, the whole continuous production mode of filling, sealing and detecting can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dry powder filling inspection device and a filling inspection method. Background technique [0002] In the prior art, manual production is used to produce B dry powder products for online use, including randomly selecting a certain number of packaging bags for air tightness testing before production, filling, weighing, and sealing during the production process, and the final finished product Generally, it is no longer tested for air tightness, and the quality of each bag of products cannot be guaranteed. [0003] In the traditional process of weighing, the upper opening of the dry powder bag is pressed together, requiring the staff to manually open the dry powder bag inlet (similar to the opening of a plastic bag), and then use the corresponding filling tool to fill the dry powder bag Dry powder, weighed after filling. The traditional operation is to use manual fillin...

Problems solved by technology

The traditional operation is to use manual filling of dry powder into dry powder bags, which is a waste of time, low in efficiency, and high cost for workers. Workers lower their heads for a long time to fill dry powder, which is prone to cervical spondylosis

[0004] At the same time, the traditional way to test the airtightness of packaging bags is to seal the empty bag first, then inflate the bag and maintain a certain pressure to detect whether there is air leakage in the bag, but this method can only be used for random inspection , and the bags after detection can no longer be used, which will cause a certain amount of waste, and there is no guarantee that every bag of products will be detected, and there is still a risk of finished product leakage
