[0041] Working principle:

[0042] When the color mixing and dosing device is working, the synchronous belt transmission is driven by the motor to drive the color mixing stirring shaft to rotate, thereby driving the color mixing head to rotate synchronously; the main material enters from the feed port of the main material feeding assembly, passes through the main material circulation channel of the feeding valve seat, and enters the inner cavity of the color mixing head seat from the mixing port; the first auxiliary material enters from the feed port of the first auxiliary material circulation channel, passes through the first auxiliary material circulation channel of the feeding valve seat, and enters the inner cavity of the color mixing head seat from the mixing port. At this time, the telescopic rods of the main material feeding cylinder and the auxiliary material feeding cylinder are both in an extended state, and the main material feeding cylinder is driven by the gear meshed with the 1 / 4 gear. The rack controls the main material feed valve core and then controls the main material and the first auxiliary material to enter the inner cavity of the color mixing head seat respectively. At this time, both the main material and the first auxiliary material can enter the inner cavity of the color mixing head seat for mixing; the second auxiliary material enters from the feed port of the second auxiliary material circulation channel, passes through the second auxiliary material circulation channel of the feed valve seat and enters the inner cavity of the color mixing head seat from the mixing port. At this time, the telescopic rods of the main material feed cylinder and the auxiliary material feed cylinder are in a retracted state, and the auxiliary material feed cylinder controls the auxiliary material feed valve core by driving the rack meshing with the 1 / 4 gear and then controls the second auxiliary material to enter the inner cavity of the color mixing head seat.

[0043] The colorant enters from the feed block of the colorant feed block, passes through the inner cavity of the colorant guide seat and the side feed hole of the colorant color matching plate, and then enters the inner cavity of the color mixing head seat from the raw material mixing hole. At this time, the ejector of the ejector cylinder is in a retracted state; the main material, auxiliary material and colorant are stirred and mixed by the rotating color mixing head in the inner cavity of the color mixing head seat and then discharged from the discharge port of the discharge seat; when the equipment needs to suspend color mixing and stirring, the ejector of the ejector cylinder extends to support the tail of the side feed hole of the colorant color matching plate to prevent the colorant from entering the inner cavity of the color mixing head seat.

[0044] In short, when the telescopic rods of the main material feeding cylinder and the auxiliary material feeding cylinder are in the extended state, the main material and the first auxiliary material will both enter the inner cavity of the color mixing head seat to be mixed and stirred with the colorant, and the second auxiliary material will circulate in the second auxiliary material circulation channel; when the telescopic rods of the main material feeding cylinder and the auxiliary material feeding cylinder are in the retracted state, the main material and the second auxiliary material will both enter the inner cavity of the color mixing head seat to be mixed and stirred with the colorant, and the first auxiliary material will circulate in the first auxiliary material circulation channel; when the telescopic rods of the main material feeding cylinder are in the retracted state and the telescopic rod of the auxiliary material feeding cylinder is in the extended state, the main material will circulate in the main material circulation channel, the first auxiliary material will circulate in the first auxiliary material circulation channel, and the second auxiliary material will circulate in the second auxiliary material circulation channel.
