The electronic filling scale adopts a high-precision all-electronic weight detection method for weighing and measurement to control the filling and filling operations of the barrel-packed raw materials. It has a high degree of automation and can minimize the spillage of materials, prevent the pollution of materials to the environment to the greatest extent, thereby providing effective labor protection for operators. At the same time, the system can be used in humid, dangerous or other adverse environments. The automatic Filling machine only needs to place the same-sized barrels neatly at the designated position, and the professional mechanical hand will accurately take out one packaging barrel each time, and precisely transport the packaging barrel to the filling nozzle through the power track. The system is manufactured using a PLC programmable controller, which is safe and reliable; the filling head and pipeline use quick connectors, which are convenient for disassembly and cleaning; it adopts a two-stage automatic filling method, with high accuracy; when the filling head is not inserted into the barrel, it will automatically lift the lever; when the filling target value is reached, the filling head will automatically rise. The automatic filling machine can freely choose between net weight and gross weight filling methods, and can set and store 30 sets of formulas for calling, and the filling target volume can be freely set, which is convenient for various weight packaging. The Filling system can be filled by one-click operation, the operation is simple, and it is equipped with a manual operation mode. The out-of-tolerance alarm and automatic control of the feeding pump function are provided. There are two windows to display the filling volume, the number of barrels, and the cumulative volume, etc. The automatic discrimination function of the skin weight range and no barrel filling function is provided. It is a fully enclosed integrated raw material filling equipment.

The electronic filling scale includes a lifting base, a support, a gear pump, a filling gun, a conveying mechanism and a control mechanism. The gear pump includes a large gear pump and a small gear pump; the double-speed filling gun and the intermediate oil tank are fixed on the support, and the single-speed filling gun is set on the lifting base. Between the lifting base and the support, there is an Electronic scale; the control circuits of the large gear pump, the small gear pump, the double-speed filling gun and the electronic scale are all electrically connected through wires to the control mechanism, to form an electronic scale-based standard barrel material filling equipment. When the filling machine is connected to the piston filling gun's pot discharge port, the power for filling is provided by the piston filling gun. After the filling machine is connected to the piston filling gun, the standard barrel is pushed to the filling machine and the filling gun is slowly lowered to the bottom of the standard barrel, after setting the material quality according to the density of the material, the automatic selection switch is turned to the automatic gear, then the piston filling gun is opened for filling. During the filling process, as the filling gun is at the bottom of the barrel, with the increase of the injected material volume in the barrel, the filling gun will automatically rise, when the material volume reaches the set value, the weighing instrument will automatically give a signal to close the filling valve.

The Liquid filling machine is driven by the forward and backward movement of the air tank to drive the piston in the material storage tank to perform reciprocating motion, achieving material suction and filling. Open the air source switch and select the manual and automatic selection switch. In the automatic gear, the piston performs reciprocating motion, and in the manual gear, gently step on the foot pedal valve to complete one reciprocating filling. (Initially, the air tank extends) Customers can choose automatic or manual gear according to factors such as production capacity, material conditions, and the operator's proficiency. After releasing the emergency stop switch, the process pneumatic switch is sensed to open, the main air path enters the rear chamber of the air tank, and the air tank moves forward, pulling the piston head forward and squeezing the material. The material passes through the one-way valve in the discharge connector into the discharge hose, and finally enters the empty barrel to be filled (the filling head is closed during filling, and opened during discharge). When the return pneumatic switch is reached, the return pneumatic switch opens. Before the main air path is switched to the front of the air tank, the air tank moves backward to pull the piston head backward, generating negative pressure in the front chamber of the material storage tank. The one-way valve opens, and the material in the feeding bucket is pressed by the atmospheric pressure into the feeding hose, through the three-way pipe into the material storage tank. During automatic filling, the air path will be switched again, repeating the operation to achieve automatic filling.
