Valve port packaging machine through the frequency converter stepless adjustment of motor speed through the size of the air conditioning feeding tube material flow rate, the whole process is completed by the microcomputer. Specific approach is in the initial stage of material filling, high-speed impeller or spiral blade will feed the material into the filling mouth, forming thrust and compressed air in the filling tube to boost the material into the bag quickly; When the material is filled to the required component of 70 or so, the motor begins to slow down, until it reaches the required packaging component, the flow pressure gradually decreases, and the section of the canned tube is gradually reduced under the effect of the cylinder, until it is completely closed after weighing.
Through the improved valve mouth type dry mortar packaging machine, because of the selection of larger diameter filling tube, accelerate the initial filling speed, reduce the phenomenon of tube blockage, increase the scale of material adaptation, packaging speed; The multi-stage control of the flow speed in the later stage can reduce the flow rate of materials quickly and ensure the packaging accuracy. Packing mouth with dust cover, useful to reduce dust diffusion, improve the working environment.
