[0034] During operation, the second regulating mechanism 14 and the third regulating mechanism 15 allow for the rapid opening and closing of multiple first valves 4 and second valves 6, which facilitates the simultaneous mixing of multiple ingredients with polypropylene raw materials, thereby improving the convenience of operation and the efficiency of mixing.

[0035] Furthermore, the second rack frame 1404 includes a third guide rail 1501, a third lead screw 1502 is movably connected to the inner wall of the third guide rail 1501, a third slider 1503 is connected to the surface of the third lead screw 1502, and the third rack frame 1504 is connected to the top of the third slider 1503.

[0036] The inner wall of the third rack frame 1504 has several sets of tooth blocks evenly distributed, and each set of tooth blocks meshes with the second gear 12 on the valve stem of several second valves 6.

[0037] During operation, it facilitates the quick opening and closing of the first valve 4 and the third valve 9, thus enabling it to be applied to the operation steps of mixing individual ingredients with water first, further improving the ease of operation.

[0039] During operation, it can simultaneously open and close multiple valves, as well as individually control a single valve, achieving versatility in regulation and ensuring the function of individually operating different proportions of ingredients.

[0040] Furthermore, the top and bottom of the first rack frame 1304 are provided with two sets of tooth blocks that are staggered, and the tooth blocks are respectively engaged with the two first gears 11.

[0041] During operation, the sliding of the first rack frame 1304 can drive the opening and closing of a first valve 4 and a third valve 9 respectively.

[0046] Working principle: First, the first lead screw 1302 is rotated, causing the first slider 1303 to slide under the guidance of the first guide rail 1301. As the first rack frame 1304 slides, it drives a first gear 11 to rotate. The first gear 11 drives the valve stem to rotate, thus opening the third valve 9. After continuing to slide, it can drive the first gear 11 to rotate in the opposite direction, thus closing the third valve 9. Then, after continuing to slide, it drives another first gear 11 to rotate, thus opening a first valve 4. After continuing to slide or in the opposite direction, it drives a first valve 4 to close. This is suitable for the operation step of mixing a single ingredient with water evenly.

[0047] When the second lead screw 1402 or the third lead screw 1502 is rotated, the second slider 1403 can slide under the guidance of the second guide rail 1401, or the third slider 1503 can slide under the guidance of the third guide rail 1501. This allows the second rack frame 1404 to drive several first gears 11 to rotate synchronously and open and close several first valves 4 simultaneously, and the third rack frame 1504 to drive several second gears 12 to rotate synchronously and open and close several second valves 6 simultaneously. This makes it suitable for mixing multiple ingredients with polypropylene raw materials at the same time.
