[0037] Example 1:

[0038] Figures 1 to 5An embodiment of the double-material filling device for row containers of the utility model is disclosed. The double-material filling device for row containers of the utility model comprises a material channel, a filling needle seat 3 and a plurality of filling needles 10 arranged at intervals in the horizontal direction.

[0039] The material channel includes a first transverse channel 33, a second transverse channel 34, a plurality of first vertical feed channels 31 and a plurality of second vertical feed channels 32. The first vertical feed channels 31 and the second vertical feed channels 32 are arranged in the needle filling seat 3. The upper area of ​​the needle filling seat 3 is the material distribution seat 8 of the needle filling seat 3. The first transverse channel 33 and the second transverse channel 34 are arranged in the material distribution seat 8 of the needle filling seat 3.

[0040] One end of each first vertical feeding channel 31 is connected to the storage device through a first transverse channel 33, and one end of each second vertical feeding channel 32 is connected to the storage device through a second transverse channel 34;

[0041] The filling needle 10 includes an inner filling needle 2 and an outer filling needle 1 sleeved on the inner filling needle 2, and a filling channel 4 is formed between the outer filling needle 1 and the inner filling needle 2;

[0042] The other end of each first vertical feeding channel 31 is communicated with the inner filling needle 2 , and the other end of each second vertical feeding channel 32 is communicated with the filling channel 4 .

[0043] During filling, solution A flows into the row of containers through the first transverse channel 33, is distributed through the multiple first vertical down-feed channels 31, and finally flows out of the inner filling needle 2 into the container to be filled. Solution B flows into the second transverse channel 34, is distributed through the multiple second vertical down-feed channels 32, and finally flows out of the filling channel 4 into the container to be filled, completing the filling of two different solutions into the same container. The row of containers of this embodiment, through the provision of inner and outer filling needles, forms two independent filling pathways, achieving dual-material filling. The structure of the row of containers of this embodiment is simple and compact, and the ratio of the two liquids can be adjusted to accommodate filling requirements of different solution ratios, resulting in high adaptability. The provision of multiple filling needles 10, first vertical down-feed channels 31, and second vertical down-feed channels 32 allows for simultaneous filling of multiple containers, resulting in high filling efficiency.

[0044] Each first vertical feeding channel 31 is in communication with each inner filling needle 2 in a one-to-one correspondence, and each second vertical feeding channel 32 is in communication with each filling channel 4 in a one-to-one correspondence.

[0045] Preferably, in this embodiment, the filling needle holder 3 includes an upper needle holder 301 and a lower needle holder 302 in addition to the material distributor 8. The upper needle holder 301 is connected to two sides of the filling block, which is connected to the external lifting assembly through the filling block to drive the filling needle 10 up and down, resulting in a simple and reliable structure. Furthermore, the upper needle holder 301 and the lower needle holder 302 are fixedly connected, and the first vertical feeding channel 31 and the second vertical feeding channel 32 extend through the upper needle holder 301. The outer filling needle 1 extends through the lower needle holder 302 and is fixedly connected to it. The inner filling needle 2 is also fixedly connected to the lower needle holder 302.

[0046] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, a feed annular groove 12 is provided between the outer wall of the outer filling needle 1 and the needle holder 3. The other end of the second vertical feed channel 32 tilts toward the first vertical feed channel 31 and connects to the filling channel 4 at the feed annular groove 12. Because the gap between the inner filling needle 2 and the filling channel 4 is relatively small, the tilted second vertical feed channel 32 prevents the first and second vertical feed channels 31 and 32 from coming too close together and causing interference, resulting in a rational layout and easy processing. Preferably, the feed annular groove 12 is provided between the outer wall of the outer filling needle 1 and the lower needle holder 302.

[0047] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, the needle holder 3 has a mounting hole 35. The outer needle 1 is sheathed over the inner needle 2, with the top of the outer needle 1 abutting against the inner needle 2. The inner needle 2 is locked into the mounting hole 35 of the needle holder 3 by the outer needle 1. The tops of the inner and outer needles 2 and 1 are sealed together by a first sealing ring 5. The needle 10 is a split-body design, with the inner and outer needles 2 and 1 sealed together by the first sealing ring 5. This simple, threadless design facilitates processing. Both the inner and outer needles 2 and 1 of each needle 10 can be independently removed for replacement or maintenance. The inner needle 2 channel and the filling channel 4 are not connected, allowing for independent filling. Preferably, the mounting hole 35 is located within the lower needle holder 302.

[0048] Furthermore, in this embodiment, if Figure 1 and Figure 2As shown, the mounting hole 35 comprises coaxially connected upper hole section 351 and lower hole section 352, the inner diameter of the upper hole section 351 is smaller than that of the lower hole section 352, the top end of the outer filling needle 1 is adapted to be sleeved in the upper hole section 351, the top end of the inner filling needle 2 is adapted to be sleeved in the upper hole section 351 and located above the outer filling needle 1, and the bottom of the filling needle base 3 is provided with a limiting mechanism for limiting the axial displacement of the outer filling needle 1. The design of the mounting hole 35 being large at the bottom and small at the top facilitates the disassembly and replacement of the filling needle 10 and can prevent the inner filling needle 2 from being damaged with the first sealing ring 5 at the top end of the outer filling needle 1 and the sealing ring between the outer filling needle 1 and the mounting hole 35 from being damaged when the filling needle 10 is installed and contacted with the mounting hole 35, thereby generating shearing and causing damage, improving the sealing effect; the filling needle 10 is limited by the limiting mechanism, and the structure is stable.

[0049] Further, as shown in Figure 1 and Figure 2 , the upper hole section 351 and the lower hole section 352 are communicated through the transition cone surface 36. The transition cone surface 36 enables the filling needle 10 to be guided into the upper hole section 351 when the filling needle 10 is installed, and can also prevent the sealing ring from being damaged due to the transition being not smooth between the upper hole section 351 and the lower hole section 352, thereby improving the sealing effect.

[0050] Further, as shown in Figure 1 and Figure 2 , the outer filling needle 1 is provided with a feeding hole 11 on the side wall in the lower hole section 352, the second vertical downward channel 32 and the filling channel 4 are communicated through the feeding hole 11, the second sealing ring 6 is arranged between the outer filling needle 1 and the inner wall of the upper hole section 351, and the third sealing ring 7 is arranged between the outer filling needle 1 and the inner wall of the lower hole section 352, the feeding ring groove 12 is located between the second sealing ring 6 and the third sealing ring 7 and communicates the second vertical downward channel 32 and the feeding hole 11. By arranging the sealing rings above and below the feeding ring groove 12, the solution in the second vertical downward channel 32 can be prevented from leaking out of the filling needle base 3, and the sealing is reliable.

[0051] Further, as shown in Figure 2 , the limiting mechanism comprises a limiting block 37 and a locking member 38, the outer wall of the outer filling needle 1 is provided with a limiting groove 13, and the limiting block 37 is fixed on the filling needle base 3 through the locking member 38 and clamped in the limiting groove 13. Since the limiting block 37 can be clamped into the limiting groove 13 only after the filling needle 10 is installed in place, the setting of the limiting groove 13 can determine whether the filling needle 10 is installed in place, and after installation is completed, the locking member 38 is locked and fixed, and the structure is reliable and stable.

[0052] Further, in the embodiment, the first horizontal channel 33 and the second horizontal channel 34 are arranged in parallel in the distribution base 8; each first vertical downward channel 31 or each second vertical downward channel 32 is arranged in parallel in the filling needle base 3, and the structure is compact and arranged reasonably.

[0053] Furthermore, in this embodiment, a first filling valve 81 is provided on the first vertical feeding channel 31, and a second filling valve 82 is provided on the second vertical feeding channel 32. By controlling the opening and closing of the first filling valve 81 and the second filling valve 82, the filling amounts of the two solutions can be independently controlled, facilitating adjustment of the ratio of the two solutions and providing greater adaptability. Preferably, both the first filling valve 81 and the second filling valve 82 are diaphragm valves.

[0054] Example 2:

[0055] Figure 6 An embodiment of the dual-material filling system for row containers in the present invention is disclosed. The dual-material filling system for row containers in this embodiment includes a first material tank 9, a second material tank 91 and the dual-material filling device for row containers of embodiment 1. The first material tank 9 is connected to the first transverse channel 33, and the second material tank 91 is connected to the second transverse channel 34.

[0056] In the row container dual-material filling system of this embodiment, the first material tank 9 and the second material tank 91 are filled with two different solutions, namely solution A and solution B. Solution A flows from the first material tank 9 through the first transverse channel 33 and the first vertical down-feed channel 31 in sequence, and flows out of the inner filling needle 2 into the container to be filled. Solution B flows from the second material tank 919 through the second transverse channel 34 and the second vertical down-feed channel 32 in sequence, and flows out of the filling channel 4 into the container to be filled, completing the filling of two different solutions into the same container. The row container dual-material filling system of this embodiment forms two independent filling passages through the arrangement of inner and outer filling needles, achieving dual-material filling. It has a simple and compact structure and can adapt to the filling requirements of different solution ratios by adjusting the ratio of the two materials. There are multiple filling needles 10, first vertical down-feed channel 31, and second vertical down-feed channel 32, so that multiple containers can be filled simultaneously, with high filling efficiency.
