[0034] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, not all embodiments. The "fixed connection" disclosed in the specific embodiments includes, but is not limited to, "welded connection, integral molding connection, detachable fixed connection achieved by setting fixing ears and bolts," etc. Fixing can be achieved based on conventional connection methods recognized by those skilled in the art. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 12 The present invention provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a dispensing mechanism 8, used for separating or uniformly filling the mixture; The head-changing mechanism 9 is used for the conversion of the injected liquid and the cleaning liquid. Hydraulic rod 5 is used to drive dispensing mechanism 8 to move downward so that liquid filling can be carried out; A rod seat 7 has a connecting rod 6 fixedly connected to its center. The top of the connecting rod 6 is connected to the output end of the hydraulic rod 5. The rod seat 7 and the connecting rod 6 are the transmission medium between the hydraulic rod 5 and the dispensing mechanism 8. By placing the filling box 2 on top of the placement plate 1 with its filling port directly below the nozzle of the dispensing mechanism 8, and then activating the hydraulic rod 5, the connecting rod 6 connected to its output end will move downward along with the dispensing mechanism 8 through the rod seat 7. Finally, the nozzle of the dispensing mechanism 8 will be inserted into the interior of the filling box 2, thereby playing a pre-treatment role for subsequent filling.

[0036] The placement plate 1 has a filling box 2 and a support frame 3 on its top. A compensation block 4 is fixedly connected to the outside of the support frame 3. The compensation block 4 is connected to a hydraulic rod 5. The placement plate 1 is used to place the filling box 2, which is a square or round box structure.

[0037] The head-changing mechanism 9 includes a square rail 91, with an inlet pipe 92 and a conical pipe 95 slidably fitted on the top of the square rail 91. The head-changing mechanism 9 also includes a first liquid-distributing plate 93, which is fixedly connected inside the inlet pipe 92 and is used to divide or separately transport the injected liquid. Then, the operator manually pushes the inlet pipe 92 inward along the square rail 91, so that the bottom of the inlet pipe 92 coincides with the dispensing mechanism 8. Then, the required mixed liquid is introduced into the inlet pipe 92. At this time, the first liquid-distributing plate 93, which is fixedly connected inside the inlet pipe 92, will transport the mixed liquid in equal portions. In addition, the first liquid-distributing plate 93 also serves to separate and transport the four different liquids without interference.

[0038] A double-ended rod 94 is fixedly connected to the top of the feed pipe 92. The end of the double-ended rod 94 away from the feed pipe 92 is connected to a conical tube 95. The conical tube 95 is connected to an external blower, which discharges the mixture adhering to the inner wall of the equipment. Because the liquid vitamin contains a certain amount of thickener, the mixture has a certain viscosity. After the mixture is filled, the feed pipe 92 is pushed in the reverse direction, causing the conical tube 95 connected to it via the double-ended rod 94 to move directly above the dispensing mechanism 8. Then, the top of the conical tube 95 is connected to the external blower, which blows all the residual mixture adhering to the inner wall of the equipment into the filling box 2. This operation can also be performed during the process of blockage, thereby ensuring the complete conveying of residual mixture and preventing blockage.

[0039] like Figure 6 , Figure 7 and Figure 8As shown, the dispensing mechanism 8 includes an outer shell tube 81, the top of which is fixedly connected to a square rail 91, and the outer side of which is fixedly connected to a rod seat 7. The transition pipe 82 is used to transport and process the incoming mixture, and the transition pipe 82 is fixedly connected to the inside of the outer casing pipe 81. The second separating plate 83 is used for further equal distribution and conveying of the mixture. The second separating plate 83 is fixedly connected inside the transition pipe 82. The bottom of the transition tube 82 is fixedly connected to the central tube 84, and the interior of the central tube 84 is fixedly connected to the third liquid separator 85; The triangular blocking plate 87 is used to release and buffer the impact force of the mixture. The triangular blocking plate 87 is rotatably connected to the ring shaft 86. Both ends of the ring shaft 86 are fixedly connected to the ring seat 815. The ring seat 815 is fixedly connected to the inner side of the central tube 84. The elastic reset strip 88 is used to reset the triangular blocking plate 87. The top end of the elastic reset strip 88 is fixedly connected to the triangular blocking plate 87, and the bottom end of the elastic reset strip 88 is fixedly connected to the inside of the central tube 84. The mixed liquid flowing from the feed pipe 92 then enters the transition pipe 82, where a second distribution plate 83 is installed, serving the same function as the first distribution plate 93. The mixed liquid then impacts the triangular block plate 87 along the transition pipe 82. The compressed triangular block plate 87 deflects downward through the ring shaft 86 and compresses the elastic reset strip 88, which resets the triangular block plate 87 until the mixed liquid continues to flow downward along the upper surface of the triangular block plate 87 and finally enters the central pipe 84. The first function of the triangular block plate 87 is to separate the transition pipe 82 from the central pipe 84, preventing dust from entering the central pipe 84 when the mixed liquid is not being transported. The second function is to reduce the impact force of the downward flow of the mixed liquid, preventing excessive wear on the central pipe 84.

[0040] like Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the bottom of the third separating plate 85 is fixedly connected to a plate sleeve 89, and the bottom of the plate sleeve 89 is inserted and adapted to the fourth separating plate 80. The inner disc 801 is used to perform preliminary retention treatment on the conveyed mixture. The surface of the inner disc 801 is interlocked with the fourth liquid distribution plate 80. The inner disc 801 is fixedly connected inside the central tube 84.

[0041] A bottom receiving block 802 is fixedly connected to the center of the bottom of the No. 4 liquid separator 80, and a round block 803 is fixedly connected to the bottom of the bottom receiving block 802. The central column 804 is used to indirectly control the lifting and lowering of the fourth liquid separator 80. The top of the central column 804 is fixedly connected to the round block 803, and the outer side of the central column 804 is fixedly connected to the column sleeve 805. The reset spring 806 is used to reset the center post 804. The bottom of the reset spring 806 is fixedly connected to the post sleeve 805, and the top of the reset spring 806 is fixedly connected to the round block 803.

[0042] A cross 807 is fixedly connected to the bottom of the central column 804; The support column 808 and the cross 807 are slidably adapted to each other, and the bottom of the support column 808 is connected to the coupling 809. The electric push rod 800 is used as the power source for discharging and filling the mixture. The top of the electric push rod 800 is connected to the branch support 808 via a coupling 809. The electric push rod 800 is fixedly connected to the bottom of the inner cavity of the central tube 84. The second retraction state of the electric push rod 800 is that the limiting sleeve 811 continues to move downward and squeezes the cross 807 downward. Then, the central column 804, which is fixedly connected to the center of the top of the cross 807, will stretch the return spring 806 and move downward along with the fourth dispensing plate 80 through the round block 803 and the bottom receiving block 802 respectively. At this time, the fourth dispensing plate 80, which is pulled downward, will be pulled out from the plate sleeve 89 and move downward through the surface of the inner disc 801 until the top of the fourth dispensing plate 80 is on the same horizontal plane as the top of the inner disc 801. Finally, the mixed liquid is no longer separated but mixed together, thereby increasing the filling speed and force of the mixed liquid when filling a filling box 2.

[0043] The limiting sleeve 811 is used to control the downward movement of the cross 807. The limiting sleeve 811 and the cross 807 are mutually squeezed and adapted. The limiting sleeve 811 is fixedly connected to the outside of the branch support 808.

[0044] An infusion tube 812 is fitted onto the surface of the inner disc 801. The infusion tube 812 passes through the inner side of the central tube 84 and extends to its outer side. A bifurcated piece 813 is fixedly connected to the top of the inner cavity of the infusion tube 812. The electric push rod 800 has two retracted states. When the limiting sleeve 811 fixedly connected to the branch support 808 moves downward and its bottom contacts the cross 807, it is in the first retracted stage. At this time, the infusion tube 812 will open, allowing the mixed liquid to flow into the filling tank 2. At this time, the mixed liquid is still in a separated state and is divided into four equal parts for outward transportation, thereby enabling the same or different mixed liquids to be equally transported into the four filling tanks 2. At the same time, one or two electric push rods 800 can be activated individually to perform infusion filling processing on one or two infusion tubes 812.

[0045] The sealing piece 814 and the branch piece 813 are fitted together to close and open the infusion tube 812. The bottom of the sealing piece 814 is fixedly connected to the branch support 808, which passes through the inside of the infusion tube 812 and extends to its outside. The central tube 84 is internally fixedly connected to a third dispensing plate 85, which functions the same as the first dispensing plate 93. At this time, four electric push rods 800 can be activated simultaneously, causing the four electric push rods 800 to drive the branch support 808 downward through the coupling 809. The top of the branch support 808 is connected to the sealing plate 814. Initially, the sealing plate 814 is engaged with the bifurcation plate 813 and seals the top of the infusion tube 812. As the branch support 808 moves downward with the sealing plate 814, the sealing plate 814 and the bifurcation plate 813 are intersected, causing the mixed liquid to flow downward from the intersection and enter the infusion tube 812. This allows the mixed liquid to enter the filling box 2 along the infusion tube 812 and achieves automatic equal-division filling.

[0046] In use, the present invention is as follows: First, the filling box 2 is placed on top of the placement plate 1, with its filling port directly below the nozzle of the dispensing mechanism 8. Then, the hydraulic rod 5 is activated, causing the connecting rod 6 connected to its output end to move downwards along with the dispensing mechanism 8 via the rod seat 7. Finally, the nozzle of the dispensing mechanism 8 is inserted into the filling box 2 to pre-process the subsequent filling. Next, the operator manually pushes the feed pipe 92 inwards along the square rail 91 until its bottom coincides with the dispensing mechanism 8. Then, the required mixed liquid is introduced into the feed pipe 92. At this time, the first dispensing plate 93, fixedly connected inside the feed pipe 92, will equally distribute the mixed liquid. Simultaneously, the first dispensing plate 93 can also separate and transport four different liquids without interference.

[0047] Immediately afterward, the mixed liquid flowing from the inlet pipe 92 enters the transition pipe 82, where a second distributor plate 83 is installed, serving the same function as the first distributor plate 93. The mixed liquid then impacts the triangular block plate 87 along the transition pipe 82. The compressed triangular block plate 87 deflects downward via the ring shaft 86, compressing the elastic reset strip 88 until the mixed liquid continues to flow downward along the upper surface of the triangular block plate 87, finally entering the central pipe 84. A third distributor plate 85 is fixedly connected inside the central pipe 84, and its function is the same as the first distributor plate 93. At this point, the mixed liquid can... The four electric push rods 800 are activated simultaneously, causing the four electric push rods 800 to drive the branch support 808 downward through the coupling 809. The top of the branch support 808 is connected to the sealing plate 814. Initially, the sealing plate 814 is engaged with the bifurcation plate 813 and seals the top of the infusion tube 812. As the branch support 808 moves downward with the sealing plate 814, the sealing plate 814 and the bifurcation plate 813 are intersected, causing the mixed liquid to flow downward from the intersection and enter the infusion tube 812, so that the mixed liquid will enter the filling box 2 along the infusion tube 812.

[0048] The electric push rod 800 has two retraction states. When the limiting sleeve 811, which is fixedly connected to the branch support 808, moves downward and its bottom contacts the cross 807, it is in the first retraction stage. At this time, the infusion tube 812 will open and allow the mixed liquid to flow into the filling box 2. At this time, the mixed liquid is still in a separated state and is divided into four equal parts for outward transportation. The second retraction state of the electric push rod 800 is that the limiting sleeve 811 continues to move downward and squeezes the cross 807 downward. Then, the central column 804, which is fixedly connected to the center of the top of the cross 807, will stretch the return spring 806 and move downward along with the fourth liquid distribution plate 80 through the round block 803 and the bottom receiving block 802 respectively. At this time, the fourth liquid distribution plate 80, which is pulled downward, will be pulled out from the plate sleeve 89 and move downward through the surface of the inner disc 801 until the top of the fourth liquid distribution plate 80 and the top of the inner disc 801 are on the same horizontal plane. Finally, the mixed liquid is no longer separated but mixed together.

[0049] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
