The automatic barrel Filling machine adopts microcomputer technology and communicates through the RS485 interface and the Modbus RTU protocol with the ARM control system. The filling machine can select the working mode to achieve preset target values and arbitrary liquid addition modes, and can automatically switch between the gravity flow mode and the pump liquid addition mode. The setting of weight parameters utilizes the intelligent weight judgment, enabling precise control at the set weight in the pump liquid addition mode, effectively avoiding errors caused by human judgment or operation. The Filling system realizes the start-stop control of the filling system based on the preset filling volume, and completes accurate measurement, display, settlement, and printing functions of the filling volume, effectively controlling overloading problems. The setting of upper and lower limits of pressure, weight, and temperature parameters realizes the emergency cut-off function in abnormal filling pipelines, effectively avoiding accidents. It can realize functions such as liquid addition times, liquid addition volumes, and liquid addition query and automatic accumulation. The automatic filling machine places the barrel in the limit hole of the hopper, moves the barrel to the exact position below the filling needle by turning the plate with the handle, sets the parameters through the control panel and performs filling. The screw rod can adjust the height of the filling needle, facilitating filling of barrels of different heights. When the mass of the barrel reaches the set parameter value, the weighing scale on the roller transmits the signal to the control panel, which controls the filling needle to stop filling, and then moves the barrel in the limit hole to the lifting platform by turning the plate with the handle. At this time, the lifting platform starts to descend under the drive of the driving component. When the lifting platform reaches the lowest point, the filled barrel is removed. With this setting, the operator does not need to move and does not need to lower the barrel, avoiding spillage of the contents in the barrel when manually lowering it, improving work efficiency while also enhancing the stability of the filling process.

The weighing filling machine is equipped with a support on the top side of the base, and a barrel is placed on the limit hole of the support. The barrel is connected to a conveying pipe at the lower end, and the conveying pipe is connected to a connection pipe at one end. The connection pipe is connected to a filling pipe at the bottom end. The connection pipe is equipped with a drip-proof and leakage prevention component. The drip-proof and leakage prevention component includes a circular groove on the top of the connection pipe, and a sealing piston head is inserted into the groove. The sealing piston head is in a sealing contact with the inner wall of the filling pipe, and a sponge block is detachably connected to the bottom of the sealing piston head. The sponge block is in a sliding and squeezing contact with the inner wall of the filling pipe. A waterproof weighing scale is set on one side of the support. A regulating component for adjusting the position of the double-layer weighing scale is set on one side of the weighing scale on the bottom side. The quantitative filling machine is equipped with a sleeve plate on the conveying pipe, and the bottom sides of both sides of the sleeve plate are connected to support plates. The cross plate is installed on the top side of the support near the top, and the support plate is connected to the top of the cross plate. A control valve is installed on the conveying pipe. One side of the connection pipe is provided with a connection hole, and one end of the conveying pipe is sealedly connected to the interior of the connection hole through the support plate. A cover plate is set on the top of the barrel, and a handle is set on the top of the cover plate. On the top of the connection pipe, an installation frame is connected, and a micro electric push rod is installed on the top of the installation frame. The piston rod of the micro electric push rod passes through the installation frame and is connected to the top of the sealing piston head. The regulating component includes two support rods passing through the connection on the cross plate, and two fixed plates are connected on both sides of the Electronic scale. Each fixed plate is connected to a sleeve, and each sleeve is slidably fitted on the support rod. Each support rod is provided with multiple adjustment holes, and each sleeve is provided with a screw, which is threaded and sleeved onto the screw nut. A guardrail is set on the top of the explosion-proof scale, and an elevated frame is set on the bottom of the stainless steel scale. On one side of the support near the bottom, a three-phase socket is set, and on one side of the support near the middle, a control panel is set. The control panel is electrically connected to the control valve, the micro electric push rod, and the scale.
