s4, when the material of small dose needs to be added, start corresponding first electric putter (29), the piston rod of first electric putter (29) drives arm-tie (30) and piston rod (31) vertical downstream, piston rod (31) no longer insert conveying pipe (23) inside this moment, material in conveying pipe (23) can normally be discharged, when needing the ejection of compact, start second electric putter (36), the piston rod of second electric putter (36) drives the vertical rebound of second plectane (34), second plectane (34) are not at conflict ejection of compact funnel (3), the hole discharge on this moment material through second plectane (34), accomplish ejection of compact process.
