The weighing filling station starts the fast feed valve and the slow feed valve at the same time to open the liquid into the barrel, when the mass of the measured liquid in the barrel reaches the preset value of the slow feed amount, the fast feed valve will be closed, and the remaining mass will be filled by the slow feed valve, and the slow feed valve will be closed when the set quantitative value is reached. PD(proportion, differentiation) is introduced in each repeat controller channel.
020-34563445After the filling bucket scale enters the automatic operation mode, open the feeding door to start feeding. The feeding device adopts a fast and slow feeding method. When the weight of the material reaches the fast feeding set value, stop the fast feeding and maintain the slow feeding. When the weight of the material reaches the final set value, close the feeding door and complete the filling process. After the material is exhausted, the discharge door of the weighing bucket is automatically closed, and the material is automatically transported downward. Perform the lid pressing and transfer to the next workstation. This process repeats automatically. The most direct and accurate way to achieve quantitative quality control is through weighing.
The filling Electronic scale is composed of an electronic scale unit, a conveying device, a cylinder filling gun, a lifting mechanism, etc. The storage bin is a buffer-type bin, which is used for material storage and provides a relatively uniform material flow; the gate is located at the bottom of the storage bin. When the equipment is under maintenance or has a malfunction, it is used to block the material inside the storage bin; the material cutting device consists of a cutting hopper, a cutting door, pneumatic components, and a supplementary air valve. During the electronic scale process, it provides fast and slow levels of feeding, and the material flows of both fast and slow feeding can be adjusted separately to ensure that the quantitative filling meets the accuracy requirements and speed requirements of measurement; the function of the supplementary air valve is to balance the air pressure difference inside the liquid Filling machine; it is mainly composed of a weighing hopper, a load-bearing bracket, and a weighing sensor, which converts the weight into an electrical signal and transmits it to the control unit; the electrical control device consists of a weighing controller, electrical components, and a control cabinet, and its function is to control the filling of benzene liquid, making the entire filling work in accordance with the pre-set program and working in an orderly manner.
