[0023] The following is for reference. Figure 1 and Figure 2 Describes the infusion control structure according to an embodiment of the present invention.

[0024] like Figure 1 and Figure 2 As shown, the filling control structure according to an embodiment of the present utility model includes a material tank 100, a speed regulating valve 200, and a filling valve 300.

[0025] The material hopper 100 has a discharge port 130 on its lower side; the speed control valve 200 includes a speed control valve pipe 210 and a speed control valve body 220, the rear end of the speed control valve pipe 210 is connected to the discharge port 130, and the speed control valve body 220 includes a rotary actuator 221 and a rotary valve core 222, as shown in the reference. Figure 3 , Figure 4The rotary actuator 221 is located outside the speed control valve tube 210, and the rotary valve core 222 is located inside the speed control valve tube 210. The rotary actuator 221 can drive the rotary valve core 222 to rotate. The rotary valve core 222 has a fast flow channel 2221 and a slow flow channel 2222. The diameter of the fast flow channel 2221 is larger than the diameter of the slow flow channel 2222. The front and rear ends of the speed control valve tube 210 can be connected through the fast flow channel 2221 or the slow flow channel 2222. The filling valve 300 is connected to the front end of the speed control valve tube 210.

[0026] For example, such as Figure 1 and Figure 2 As shown, the storage tank 100 serves as a container for liquid materials. The storage tank 100 has a discharge port 130 on its lower side, capable of discharging liquid materials. The speed control valve 200 includes a speed control valve pipe 210 and a speed control valve body 220. The rear end of the speed control valve pipe 210 is connected to the discharge port 130, allowing liquid materials to enter the speed control valve pipe 210 of the speed control valve 200. (Refer to...) Figure 3 , Figure 4 The speed control valve body 220 includes a rotary actuator 221 and a rotary valve core 222. The rotary actuator 221 is located outside the speed control valve tube 210, and the rotary valve core 222 is located inside the speed control valve tube 210. The rotary actuator 221 can drive the rotary valve core 222 to rotate. The rotary valve core 222 has a fast flow channel 2221 and a slow flow channel 2222, with the diameter of the fast flow channel 2221 being larger than the diameter of the slow flow channel 2222. That is, when the rotary valve core 222 rotates, the fast flow channel 2221 and the slow flow channel 2222 will also rotate and switch angles. The front and rear ends of the speed control valve tube 210 can be connected through either the fast flow channel 2221 or the slow flow channel 2222, meaning the speed control valve tube 210 can be selectively connected through either the fast flow channel 2221 or the slow flow channel 2222. The filling valve 300 is connected to the front end of the speed control valve tube 210 and is responsible for filling the liquid material into the bottle.

[0027] In actual operation, taking ink as a liquid material as an example, the ink will be stored in the material container 100. When ink needs to be filled, first place the bottle to be filled in the corresponding position of the filling valve 300, and then open the filling valve 300 to start the work of filling the ink into the bottle.

[0028] When the filling valve 300 is opened, the ink in the material tank 100 enters the speed control valve pipe 210 of the speed control valve 200 through the outlet 130. The speed control valve body 220 of the speed control valve 200 controls the switching operation between the fast flow channel 2221 and the slow flow channel 2222 by controlling the rotation of the rotary valve core 222.

[0029] Reference Figure 5When the rotary valve core 222 switches to the state where the fast flow channel 2221 connects to the speed control valve tube 210, that is, the two ends of the speed control valve tube 210 can be connected through the fast flow channel 2221. In this way, the larger diameter of the fast flow channel 2221 can be used to enable the filling valve 300 to fill ink into the bottle at a faster flow rate, thereby improving the efficiency of the filling process.

[0030] When the rotary valve core 222 switches to the state where the slow flow channel 2222 connects to the speed control valve tube 210, that is, the two ends of the speed control valve tube 210 can be connected through the slow flow channel 2222. This allows the filling valve 300 to fill the bottle with ink at a slower flow rate by utilizing the smaller diameter of the slow flow channel 2222. And when the filling speed is reduced, the accuracy of detecting the amount of ink in the bottle can be improved.

[0031] By using the above method, we can achieve the goal of rapid filling by utilizing the fast flow channel 2221 and improve filling efficiency, while also improving the detection accuracy control by combining the slow flow channel 2222 with the slow filling, thus avoiding waste and increased costs caused by excessive liquid material actually being filled into the bottle.

[0032] In some embodiments of this utility model, the speed regulating valve pipe 210 has a valve body cavity 211. The rear end of the valve body cavity 211 is connected to the discharge port 130 through the speed regulating valve rear pipe 212, and the front end of the valve body cavity 211 is connected to the filling valve 300 through the speed regulating valve front pipe 213. The rotary valve core 222 is located inside the valve body cavity 211. A side pipe 214 is provided on the right side of the valve body cavity 211. The rotary actuator 221 is connected to the side pipe 214. The rotary actuator 221 is provided with a rotating shaft 2211. The rotating shaft 2211 passes through the side pipe 214 and is connected to the rotary valve core 222. The rotary actuator 221 can control the rotary valve core 222 to rotate to a fast flow state or a slow flow state. When the speed regulating valve 200 is in the fast flow state, the front and rear ends of the fast flow channel 2221 are connected to the speed regulating valve front pipe 213 and the speed regulating valve rear pipe 212, respectively. When the speed control valve 200 is in slow flow state, the front and rear ends of the slow flow channel 2222 are connected to the front pipe 213 and the rear pipe 212 of the speed control valve, respectively.

[0033] The speed control valve pipe 210 has a sufficiently precise valve body cavity 211. The front and rear ends of this valve body cavity 211 are connected to the front speed control valve pipe 213 and the rear speed control valve pipe 212, forming a continuous pipeline structure. The rear speed control valve pipe 212 at the rear end of the valve body cavity 211 is tightly connected to the discharge port 130 to ensure smooth material flow. The front speed control valve pipe 213 at the front end of the valve body cavity 211 is connected to the filling valve 300 to ensure precise control of the filling process.

[0034] The rotary valve core 222 inside the valve body cavity 211 is the core of the speed control valve body 220. The rotary actuator 221 is equipped with a rotary shaft 2211 that is fixedly connected to the rotary valve core 222, ensuring that the rotary actuator 221 can accurately control the rotation of the rotary valve core 222, allowing the rotary valve core 222 to flexibly switch between fast flow and slow flow states. Specifically, when the speed control valve 200 is in the fast flow state, the front and rear ends of the fast flow channel 2221 are unobstructedly connected to the front pipe 213 and the rear pipe 212 of the speed control valve, respectively, while the two ends of the slow flow channel 2222 are blocked by the inner wall of the valve body cavity 211, ensuring that the material passes through at a higher flow rate. Conversely, when the speed control valve 200 switches to the slow flow state, the front and rear ends of the slow flow channel 2222 are connected to the front pipe 213 and the rear pipe 212 of the speed control valve, respectively, while the two ends of the fast flow channel 2221 are blocked by the inner wall of the valve body cavity 211, thereby controlling the material to flow smoothly at a lower flow rate. This design not only achieves the purpose of rapid filling and improves filling efficiency, but also enables precise filling when combined with detection accuracy.

[0035] In some embodiments of this utility model, the fast flow channel 2221 and the slow flow channel 2222 of the rotary valve core 222 can be staggered and do not intersect, or they can intersect to form a cross-shaped structure.

[0036] In some embodiments of this utility model, valve body cavity sealing rings 215 are provided on the front and rear sides of the valve body cavity 211 to prevent fluid from leaking from the gap between the inner wall of the valve body cavity 211 and the outer wall of the rotary valve core 222, thereby affecting the adjustment effect of the rotary valve core 222.

[0037] In some embodiments of this utility model, the rotary drive 221 employs a pneumatic actuator. Pneumatic actuators offer advantages such as rapid response, low cost, and simple maintenance. In particular, they can quickly complete actions, making them suitable for applications requiring high-frequency operation of the speed control valve 200. Therefore, the rotary drive 221 uses a pneumatic actuator as the core driving component of the speed control valve 200, which is sufficient to ensure the stability and efficiency of the rotary action.

[0038] In some embodiments of this utility model, a manual valve 400 is provided between the front end of the speed regulating valve pipe 210 and the filling valve 300. The manual valve 400 is used to manually close and stop the filling work after the filling is completed, and can also manually adjust the fluid flow rate when necessary, so as to realize more control over the filling process.

[0039] In some embodiments of this utility model, a waterproof and breathable hole 230 is provided on the speed control valve tube 210, and a waterproof and breathable membrane is embedded in the waterproof and breathable hole 230. That is, the waterproof and breathable hole 230 is provided on the surface of the speed control valve tube 210, and the waterproof and breathable membrane that meets the performance requirements is embedded inside the waterproof and breathable hole 230. This is intended to discharge gas inside the speed control valve tube 210 without leaking liquid material, which helps to ensure that the liquid material inside the speed control valve tube 210 can maintain smooth flow and effectively prevents the liquid material from being unable to be discharged smoothly due to insufficient pressure inside the speed control valve tube 210.

[0040] In some embodiments of this utility model, the waterproof vent 230 is located on the valve body cavity 211 of the speed control valve pipe 210, and the waterproof vent 230 can correspond to the fast flow channel 2221 or the slow flow channel 2222. When the speed control valve 200 is in the fast flow state, the front and rear ends of the fast flow channel 2221 are connected to the front pipe 213 and the rear pipe 212 of the speed control valve, respectively, while the slow flow channel 2222 is connected to the waterproof vent 230. When the speed control valve 200 is in the slow flow state, the front and rear ends of the slow flow channel 2222 are connected to the front pipe 213 and the rear pipe 212 of the speed control valve, respectively, while the fast flow channel 2221 is connected to the waterproof vent 230, which can accelerate the exhaust. This ensures that the exhaust process is coordinated with the switching process of the fast flow channel 2221 and the slow flow channel 2222, further ensuring smoother flow of liquid materials inside the speed control valve pipe 210.

[0041] An ink filling machine according to a second aspect embodiment of the present invention includes a filling control structure according to the first aspect embodiment of the present invention described above. (Refer to...) Figure 1 , Figure 2 This utility model ink filling machine also includes a base 500, with the lower side of the material tank 100 connected to the rear side of the base 500. A receiving platform 600 is provided on the front side of the base 500, located below the filling valve 300. In actual operation, the ink is initially in the material tank 100. When ink needs to be filled, the bottle to be filled is placed on the receiving platform 600, and the filling valve 300 is opened to begin filling the bottle with ink.

[0042] The ink filling machine according to the present invention reduces filling waste by adopting the above-described filling control structure, which facilitates cost reduction and waste reduction in ink filling and improves ink filling efficiency.

[0043] In some embodiments of this utility model, reference is made to Figure 2The lower side of the material bucket 100 is connected to the rear side of the base 500 through a lifting structure 700. The lifting structure 700 includes a fixed rod 710 on the lower side, a movable rod 720 on the upper side, and a fixing structure 730. The upper end of the fixed rod 710 slides into the lower end of the movable rod 720. The lower end of the fixed rod 710 is connected to the base, and the upper end of the movable rod 720 is connected to the material bucket 100. The fixing structure 730 can fix the fixed rod 710 and the movable rod 720.

[0044] The material tank 100 is connected to the base 500 via a lifting structure 700, facilitating height adjustment of the material tank 100 to accommodate different bottle heights. A fixed rod 710 slides into and engages with a movable rod 720, ensuring movement between the two. The lower end of the fixed rod 710 is securely connected to the base 500, while the upper end of the movable rod 720 is connected to the material tank 100. Adjusting the height of the movable rod 720 adjusts the height of the material tank 100, consequently adjusting the height of the speed control valve 200 and the filling valve 300 connected to the material tank 100.

[0045] The main function of the fixing structure 730 is to effectively fix the fixing rod 710 and the movable rod 720, ensuring that the material bucket 100 can be fixed and maintained stable after the height is adjusted. For example, the fixing structure 730 can be a pin, with several through holes distributed on both the fixing rod 710 and the movable rod 720. After the height of the movable rod 720 is adjusted, the fixing structure 730 can be inserted into the corresponding through holes of the fixing rod 710 and the movable rod 720 to fix the material bucket 100. Alternatively, the fixing structure 730 can be a locking screw sleeve, with the fixing rod 710 having a threaded clamp. After the height of the movable rod 720 is adjusted, the fixing structure 730 can be tightened on the threaded clamp, causing the threaded clamp to clamp the movable rod 720, thus fixing the material bucket 100, and so on.

[0046] In some embodiments of this utility model, reference is made to Figure 2 , Figure 6 A positioner 610 is provided on the receiving platform 600. The positioner 610 includes a positioner fixing seat 611, a hand-tightening bolt 612 and a limiting plate 613. The lower side of the positioner fixing seat 611 is connected to the receiving platform 600. The limiting plate 613 has an elongated hole 6131. ​​The hand-tightening bolt 612 passes through the elongated hole 6131 and is threaded to the upper side of the positioner fixing seat 611. The hand-tightening bolt 612 can press the limiting plate 613 tightly.

[0047] In some specific embodiments of this utility model, the positioner 610 on the receiving platform 600 is used to position the bottle on the receiving platform 600, making it easier for the bottle to be aligned with the filling valve 300.

[0048] The positioning plate 613 of the positioner 610 can be adjusted to accommodate bottles of different sizes and shapes. Specifically, a hand-tightening bolt 612 passes through this elongated hole 6131 and is threadedly connected to the upper part of the positioner fixing seat 611. When the hand-tightening bolt 612 is loosened, the positioning plate 613 can move along the elongated hole 6131. ​​When the hand-tightening bolt 612 is tightened, the positioning plate 613 is pressed and fixed, thereby ensuring accurate positioning.

[0049] In some embodiments of this utility model, the base 500 has a weighing cavity 510 on the front side, and a weighing sensor 620 is provided in the weighing cavity 510. The lower side of the weighing sensor 620 is connected to the bottom wall of the weighing cavity 510, and the upper side of the weighing sensor 620 is connected to the lower side of the receiving platform 600.

[0050] In some other embodiments of this utility model, the front part of the base 500 is designed with a weighing cavity 510, and a weighing sensor 620 is installed inside the weighing cavity 510. The lower part of the weighing sensor 620 is firmly connected to the bottom wall of the weighing cavity 510, while the upper part of the weighing sensor 620 is connected to the lower part of the receiving platform 600. This design can ensure the accuracy and stability of the weighing data.

[0051] In some embodiments of this utility model, a stirring motor 110 is provided on the upper side of the material tank 100, and a stirrer 120 is provided inside the material tank 100. The stirring motor 110 is connected to the stirrer 120 through a stirring motor shaft 111. The stirrer 120 stirs the ink in the material tank 100 to ensure that the ink remains uniform and to avoid local solidification and clumping of the ink, which would cause waste.

[0052] In some embodiments of this utility model, an injection pipe 140 is connected to the rear side of the material tank 100 for injecting ink into the material tank 100.

[0060] According to the filling control structure of this utility model embodiment, the following effects can be achieved by setting it up as follows: When the rotary valve core 222 switches to the state where the fast flow channel 2221 is connected to the speed regulating valve tube 210, the larger diameter of the fast flow channel 2221 can be used to enable the filling valve 300 to fill the bottle with ink at a faster flow rate, thereby improving the efficiency of the filling process; when the rotary valve core 222 switches to the state where the slow flow channel 2222 is connected to the speed regulating valve tube 210, the smaller diameter of the slow flow channel 2222 can be used to enable the filling valve 300 to fill the bottle with ink at a slower flow rate, thereby improving the detection accuracy of the amount of ink in the bottle; through the above fast and slow flow switching method, the purpose of fast filling using the fast flow channel 2221 is achieved, improving filling efficiency, and the detection accuracy control is improved by combining the slow filling of the slow flow channel 2222, avoiding excessive liquid material actually filled into the bottle, which would cause waste and increase costs.
