[0022] In order to better understand the present invention, the following is a detailed description with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] like Figure 1 As shown, a double-station slurry mixing system is used to centrally transport slurries of different color numbers to form color pastes used for rotary screen printing. It includes multiple dye tanks, multiple delivery pumps, and a first discharging mechanism and a second discharging mechanism. A color paste barrel is provided below the first discharging mechanism and the second discharging mechanism. Each dye tank contains dyes of different color numbers. To facilitate the distinction between different color numbers, each dye tank is printed or pasted with a number. In order to improve production efficiency, the slurry mixing system described in this embodiment is provided with two sets of discharging mechanisms on the basis of using the same set of dye tanks. The operation status of different delivery pumps is controlled by a controller to realize simultaneous feeding of the two sets of discharging mechanisms. As shown Figure 2 As shown, the first and second discharging mechanisms each include a circular discharging plate with several through-holes arranged thereon, each of which houses a discharging connector. Both the upper and lower ends of the connector are equipped with pagoda connectors. The upper pagoda connector is used to connect to the feed pipe, while the lower pagoda connector is connected to the discharging nozzle. To facilitate discharging, the lower end of the discharging nozzle is tapered. The discharging nozzle can be made of glass, polytetrafluoroethylene, or PE. If PE is used, a polytetrafluoroethylene hydrophobic layer can be further provided on its inner wall. To facilitate observation of the discharging process, the discharging nozzle is made of a transparent material.

[0025] Each dye tank is equipped with a first feed pipe and a second feed pipe. The first feed pipe is connected to a pagoda connector at the upper end of the first discharging mechanism via a feed pump, and the second feed pipe is connected to a pagoda connector at the upper end of the second discharging mechanism via a feed pump, so that each dye tank is connected to the first and second discharging mechanisms. To facilitate the connection and differentiation of the delivery paths of the different color slurries, the feed pump and the discharge connector are each provided with a number corresponding to the dye tank. In this embodiment, the infusion pump uses a DC peristaltic pump. This type of peristaltic pump is easy to electrically control and can rotate forward or reverse. Its flow rate increases with the increase of applied voltage, allowing for more accurate quantitative delivery. All peristaltic pumps are electrically connected to a PLC controller, which controls the delivery flow rate of each peristaltic pump's delivery path. The PLC controller obtains the preset delivery amount and delivery sequence of each color slurry through a host computer connected to it, and then starts the corresponding peristaltic pump to run for a specific time, thereby achieving simultaneous delivery of a fixed amount of dye liquor of different color numbers from two color slurry barrels.

[0026] The dual-station slurry mixing system described in this embodiment utilizes a single set of dye tanks, eliminating the need for multiple sets. This reduces dye redundancy and saves production costs. Combined with a delivery pump and first and second discharging mechanisms, it automatically delivers a fixed amount of color paste, efficiently preparing different colors of printing paste with high delivery efficiency and minimal operational error.

[0027] Example 2

[0028] like Figure 3 The figure shows a dual-station slurry mixing system, comprising multiple dye tanks, multiple delivery pumps, and first and second discharging mechanisms, each with a color paste barrel positioned below it. Each of the first and second discharging mechanisms comprises a circular discharging plate with several through-holes arranged therein, each fitted with a discharging connector. Both the top and bottom ends of the connector are fitted with pagoda connectors. The top pagoda connector is used to connect to the feed pipe, while the bottom pagoda connector is connected to the discharging nozzle. To facilitate discharging, the lower end of the discharging nozzle is tapered and made of polytetrafluoroethylene. To facilitate observation of the discharging process, the nozzle is made of a transparent material.

[0029] Each dye tank is equipped with a feed pipe, each of which is connected to the liquid inlet of a corresponding delivery pump, and the liquid outlet of the delivery pump is connected to a Y-shaped feed pipe. The two branches of the Y-shaped feed pipe are respectively connected to the pagoda joints at the upper ends of the first and second discharging mechanisms. Solenoid valves are installed on both branches of the Y-shaped feed pipe, and the solenoid valves and the delivery pump are electrically connected to the PLC controller. To further improve the accuracy of delivery, a weighing device is also provided. In this embodiment, the weighing device uses an electronic scale, which is electrically connected to the PLC controller and can transmit the real-time weighing weight to the PLC controller. The PLC controller starts the corresponding peristaltic pump in sequence based on the delivery volume and delivery sequence of each color paste preset in the system, and simultaneously controls the opening of the corresponding solenoid valve to deliver the corresponding slurry. The controller receives the weight value transmitted by the electronic scale in real time and adjusts the driving voltage of the peristaltic pump according to the remaining delivery volume. When the remaining delivery volume is large, it drives at high voltage, and when the remaining delivery volume is small, it drives at low voltage. When the preset amount is reached, the peristaltic pump and solenoid valve are turned off to achieve accurate and efficient delivery.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
