Embodiment Construction

[0016] exist figure 1 Among them, the airtight metering mechanism for bagged materials in the present invention consists of upper and lower parts that do not touch. Tightening mechanism 5, shaft 6, load cell 7, sealing strip 8. The vacuum port 11 is located at the bottom of the discharge pipe 12, and the feed pipe 1 is located at a certain distance below the discharge pipe 12. When feeding, the vacuum port 11 is opened, and a vacuum airflow is formed in the annular zone between the feed pipe 1 and the discharge pipe 12 to avoid Dust spills and dust flying. From the beginning of feeding to the end of feeding, the influence of vacuum air flow on metering is relatively constant, so as to ensure that the metering accuracy is not affected.

[0017] The fixed splint 4, the movable splint 3 are connected with the feed pipe 1 with 4 shafts 6, and the fixed splint 4 is fixed on the load cell 7. When installing the material bag 9, open the tensioner 5, lift the movable splint 3 and t...

Abstract

The invention relates to a bagged material airtight metering mechanism comprising a discharging tube, a vacuum port, a feeding tube, a movable clamp plate, a fixed clamp plate, a shaft, a locking mechanism, a weighing sensor and a sealing strip. The mechanism simultaneously carries out the opening of the port of a material bag, clamping and fixation, feeding, dust suction and metering, the weighing part is not in contact with other objects, and the mechanism ensures that the precision reaches or exceeds 0.1%; and the port of the material bag is sealed to avoid the leakage and the flying of dust.

Description

Technical field [0001] The invention belongs to the field of metering and packaging, and relates to a bagged material airtight metering mechanism, especially a bagged material airtight metering mechanism for high-precision metering. Background technique [0002] In order to ensure that the accuracy reaches or exceeds 0.1% when bagging powder and granular materials with a measuring range of 100g to 5kg, manual loading is usually used, which will cause dust leakage or dust flying, which will damage the operator's safety. Physical health, pollution of the environment and materials. Contents of the invention [0003] In order to ensure the metering accuracy of powder and granular materials in bags and avoid dust leakage and dust flying, the invention provides a sealed metering mechanism for bagged materials. The mechanism stretches, clamps and fixes the mouth of the material bag, feeds, vacuums, and measures at the same time, and the weighing part does not contact with other ...
