[0029] Through the above technical solution, a material distribution bin 202 is set for material storage, and the servo motor 302 drives the feeding auger 304 to rotate at a fixed angle and a fixed speed. The quantitative rotation of the feeding auger 304 transmits the additives entering the batching barrel 301 in equal amounts out of the batching barrel 301 for additive addition. The added metering can be achieved by controlling the servo motor 302, thereby achieving the effect of accurately adding powder and granular additives.

[0030] The interior of the additive storage box 201 is divided into multiple sub-bins 202, and multiple groups of quantitative distribution devices 3 are set at the same time, and the servo motors 302 on the multiple groups of quantitative distribution devices 3 are controlled individually. Therefore, when the product is processed, by controlling the switch and speed of different servo motors 302, multiple additives can be added simultaneously and in unequal amounts, achieving the effect of adding different additives in batches and in unequal amounts.

[0031] Specifically, the support device 1 includes a support frame body 101, the top of the support frame body 101 is fixedly connected to an upper traction frame 102, the middle of the support frame body 101 is fixedly connected to a waist traction frame 103, the upper traction frame 102 is fixedly connected to the additive storage box 201, and the waist traction frame 103 is fixedly connected to the dispensing barrel 301.
