[0033] By adopting the above technical solution, the device can start to adjust the opening size of the first slot 7 through the adjustment mechanism, so that the operator can adjust the appropriate raw material feeding rate according to actual needs, thereby greatly improving the accuracy of the ingredient ratio of the device.
[0034] In the implementation mode of the present application, Figure 2 and Figure 4 As shown, the intermittent mechanism includes a half-gear disc 13 installed on the outer surface of the stirring shaft 3 and a two-way tooth plate 14 movably installed on the top of the stirring box 1.
