[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Please refer to Figure 1 and Figure 2 One embodiment of the utility model provides a multi-material automatic filling device, which is mainly used to mix a variety of chemical raw materials in proportion to generate new chemical products; for example: methyl bromide, dimethyl ether.

[0021] A multi-material automatic filling device comprises: a control mainboard and a plurality of filling units. The control mainboard and the plurality of filling units transmit data to each other through photoelectric isolation and a 485 communication circuit.

[0022] The control motherboard includes a high-performance main processor, a storage unit, a precision clock circuit and a cloud server interface. The storage unit is interconnected with the high-performance main processor data, and the storage unit includes a large-capacity data storage circuit for storing the data of the control motherboard and the charging unit. The precision clock circuit is interconnected with the high-performance main processor signal, and the precision clock circuit ensures the stability and accuracy of the system. There are two main ways to interface with the cloud server. The first is to connect the local computer through the serial port to WIFI or Ethernet, the local computer is connected to the cloud server, and the cloud server is connected to the mobile terminal. The second is to connect the cloud server through the serial port to the 4G module, the 4G module is connected to the cloud server, and the cloud server is connected to the management department. Both methods of connection are bidirectional.

[0023] The filling unit includes a signal acquisition control board and a material storage tank. The signal acquisition control board controls the corresponding filling pipeline and thus controls the output of the material storage tank. The number and placement of the signal acquisition control board and the material storage tank are not limited and can be set according to actual site requirements.

[0024] The signal acquisition control board includes a processor, a weighing sensor, a filling valve control terminal and a discharge valve control terminal. The weighing sensor transmits data to the processor through photoelectric isolation and a 24-bit analog signal acquisition circuit. The processor transmits control signals to the filling valve control terminal and the discharge valve control terminal through photoelectric isolation and output circuits. The weighing sensor measures weight information and inputs it into the processor for analysis and processing. The processor controls the filling valve control terminal and the discharge valve control terminal according to the collected data and control instructions, thereby realizing the filling of materials.

[0025] The control mainboard controls several filling units to convey different materials. The control mainboard can control several filling units simultaneously or successively.

[0026] The filling pipeline includes a filling valve, a metering tank and a discharge valve in sequence according to the material conveying direction. The filling valve is opened and closed by the filling valve control end, and the discharge valve is opened and closed by the discharge valve control end.

[0027] The following is the material filling process, which is divided into the filling process and the discharge process:

[0028] Filling process: the discharge valve is closed. The discharge valve needs to be closed first to prevent the material from being discharged in advance. The signal acquisition control board controls the filling valve to open. The metering tank transmits the measured material data information to the signal acquisition control board. After filling to the rated value, the signal acquisition control board controls the filling valve to close.

[0029] Discharging process: The signal acquisition control board controls the discharging valve to open, allowing the material temporarily stored in the metering tank to be released. After the discharging is completed, the signal acquisition control board controls the discharging valve to close.

[0030] According to the actual situation of the station, the output pipes of several filling units can all lead to the mixing tank. Alternatively, the output pipes of several filling units can lead to different storage tanks. The control mainboard can control the proportion and sequence of different materials, and can also control different filling units to fill according to different situations. For example, if the material storage tank is occupied or the material is insufficient, the control mainboard can only allocate different filling units.

[0031] Compared with the existing technology, a control main board can simultaneously interconnect with several signal acquisition control boards, and can obtain and control the working conditions of each inflation station, saving labor costs and increasing work efficiency.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
