A volume metering device for granular material packaging machine with automatic self-turning plate

Abstract

The invention discloses a servo automatic-flap volumetric measuring device of a particle material packing machine. The volumetric measuring device comprises two vertical plates, a bottom mounting plate is fixed between the two vertical plates, guide rails are symmetrically arranged on the bottom mounting plate, a measuring plate is supported through the guide rails, multiple measurement spigots are evenly formed in the measuring plate, a measurement adjusting block is arranged in each measurement spigot, and a measuring cavity is formed between the measurement adjusting block and the inner end of corresponding measurement spigot; an adjusting and fixing strip is fixed in front of the measuring plate, and a packed volume adjusting component is arranged between each measurement adjusting block and the adjusting and fixing strip; a material feed flap is hinged to a position corresponding to each measuring cavity below the measuring plate and used for controlling the opening and the closing of the corresponding measuring cavity; a material storage bin is arranged between the two vertical plates and located over the measuring plate; the device is further provided with a reciprocation driving mechanism. By means of the servo automatic-flap volumetric measuring device of the particle material packing machine, a dynamic online adjustment on the packed volume size can be achieved without stopping the machine, materials are not prone to leaking, the packed materials and packing materials can be saved, and the production efficiency and the packing quality are improved.

Description

technical field [0001] The invention relates to a metering device, in particular to a volumetric metering device for a granular material packing machine with an automatic self-turning plate. Background technique [0002] Granular materials are an important form of oral solid drugs, and the minimum packaging unit is generally between 1g and 10g. The National Pharmacopoeia stipulates that the deviation between the actual loading amount and the specified loading amount should be less than ±5%, the particle size range is between 20 mesh and 40 mesh, and the fine powder (>80 mesh) content is less than 5%. According to the above requirements, the bulk density of the mixed granular materials is basically at a stable value. In actual production, the general Chinese medicine materials are between 0.50-0.55g / ml, and the western medicine materials are about 0.60g / ml, which is the volume of the materials. It has a relatively stable linear relationship with its weight. Therefore, ph...

Time consuming and waste of packaging material

In addition, in this way, the triangular bucket and the side wall of the metering plate are close together, and the fine powder can easily leak from the gap between the two under the action of gravity, which will cause powder to be trapped in the packaging bag and affect the sealing quality.

Therefore, the installation accuracy is extremely high and the use is difficult
