Description

Technical Field

[0001] This utility model relates to the field of liquid material filling, and in particular to a liquid material loading system. Background Technology

[0002] The current liquid material filling system mainly consists of a weighing and metering system and a PLC controller, with functions limited to data acquisition and basic control. Its process relies on manual operation, and the specific steps are as follows: the vehicle drives into the loading arm position, and the anti-slip sleepers are placed manually; the loading arm mechanism is lowered and locked manually; the operator and the computer work together to complete the tare, filling start and completion signal confirmation; the sleepers are retrieved manually and the equipment is checked and reset.

[0003] However, existing liquid material filling equipment relies too heavily on manual judgment of the timing of operation during the filling process, which poses a significant risk of misjudgment and risks such as the loading arm being pulled off by the vehicle and the vehicle rolling away. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing liquid material filling equipment, which relies too much on manual judgment of the timing of operation during the filling process, and to provide a liquid material loading system.

[0005] This utility model provides a loading system for liquid materials, including: The base is equipped with a weighing mechanism, an arm loading mechanism, a control unit, and a positioning mechanism. The weighing mechanism is nested in the base and is movably connected to the base. The loading arm mechanism is spaced apart from the weighing mechanism, and the positioning mechanism is spaced apart from the weighing mechanism. The loading arm mechanism is provided with a position adjustment component. The control unit is communicatively connected to the position adjustment component, the weighing mechanism, the loading arm mechanism, and the positioning mechanism, respectively. The positioning mechanism is used to detect the vehicle's parking position, and the loading arm mechanism is used to fill the vehicle with liquid materials.

[0006] This utility model discloses a liquid material loading system. A weighing mechanism is nested on a base. When a vehicle is positioned on the weighing mechanism, the weighing mechanism measures the vehicle's weight, thereby controlling the amount of liquid material injected and preventing spillage. A positioning mechanism positions the vehicle on the base, ensuring it enters the filling range, allowing the loading arm to fill the vehicle. The loading arm is used to fill the vehicle with liquid material. The loading arm and the positioning mechanism are spaced apart to avoid affecting the weighing results. A position adjustment component adjusts the position of the loading arm, ensuring accurate entry of the liquid material into the vehicle's storage tank. The control unit analyzes data collected by the weighing and positioning mechanisms to control the actions of the position adjustment component and the loading arm, achieving automatic vehicle filling and preventing human error.

[0007] Preferably, the base is further provided with a static electricity elimination mechanism, which can be connected to the vehicle.

[0010] When the vehicle is parked on the weighing mechanism, the electrostatic induction unit is located below the vehicle. The electrostatic induction unit determines the static electricity on the vehicle by sensing the magnitude of the electric potential on the vehicle. The electrostatic induction unit is a non-contact static voltage tester. When the magnitude of the electric potential on the vehicle exceeds the threshold set by the control unit, the control unit sends an action signal to the contact device. The contact device then contacts the vehicle, causing the vehicle to conduct and discharge with the ground.

[0013] Preferably, the weighing mechanism includes a plate body, which is nested in the base and slidably connected to the base. A weighing sensor is provided on the plate body, and the weighing sensor is communicatively connected to the control unit.

[0014] The vehicle's weight is measured by a weighing sensor. The control unit uses this weight information to control the loading arm to inject liquid material into the vehicle or stop injecting liquid material into the vehicle.

[0017] Preferably, the loading arm mechanism includes a pumping mechanism, a telescopic pipe section, and a nozzle. One end of the telescopic pipe section is connected to the pumping mechanism, and the other end is connected to the nozzle. The control unit is controlled by the telescopic pipe section and the pumping mechanism.

[0021] Preferably, the nozzle is equipped with a pressure sensor, which is communicatively connected to the control unit.

[0022] Feedback from the pressure sensor enables the control unit to sense the connection status between the nozzle and the vehicle, preventing liquid material leakage.

[0023] Preferably, the control unit includes a PLC controller and an operation screen, the PLC controller is communicatively connected to the operation screen, and the PLC controller is communicatively connected to the position adjustment component, the weighing mechanism, the loading arm mechanism, and the positioning mechanism.

However, it should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0029] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.
