Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
embodiment 1,see shown in Fig. 1-3, a kind of feeding mechanism of extruder, comprise hopper 1, feeding square cylinder 2, blanking barrel 3, feed screw 4, base plate 5 and driving mechanism 6, feeding square cylinder 2 and driving mechanism 6 are all arranged at base plate 5, hopper 1 and blanking barrel 3 are all communicated with feeding square cylinder 2, feed screw 4 to be arranged in feeding square cylinder 2 and to be connected to the output of driving mechanism 6, and feed screw 4 is set to double-screw type feed screw.When the utility model conveying extruding, solve that extruding machine pan feeding is uneven, speed speed not etc., uneven, the raw material caking of material dispersion takes the problem of encircleing not charging, importantly can ensure the continuity of feeding mouth feeding, can also mutually from clear screw rod retentate.
Preferably, feed screw 4 comprises the first feed screw 41 and the spacing of the second feed screw 42, first feed screw 41 of be arrangeding in parallel with the first feed screw 41 and the second feed screw 42 is greater than 2cm.The rotating part 432 that first feed screw 41 or the second feed screw 42 comprise helical axis 431 and connect as one with helical axis 431, the rotating part body 4322 that rotating part 432 comprises contact site 4321 and is connected with contact site 4321 arc structure.There is no gap in the middle of this structure, there is good self-cleaning function, and have very high measuring accuracy; Be applicable to the feeding of larger material, improve feeding capacity, feeding ability and Pouring oar.
Preferably, hopper 1 comprises hopper body 11 and visor 12, and visor 12 arranges hopper body 11 outer surface, hopper body 11 is stainless steel, achieve antirust effect, the setting of visor 12 is convenient to observe material surplus in hopper 1, and hopper 1 is arranged at the top of feeding square cylinder 2.
Preferably, driving mechanism 6 comprises cycloidal pin reductor 62, buncher 63 and gear-box 64, and the output of buncher 63 is connected with the input of cycloidal pin reductor 62, and the output of cycloidal pin reductor 62 is connected with gear-box 64 input.The design of cycloidal pin reductor 62 is selected, and makes overall driving mechanism 6 mounting structure more compact, achieves less space mounting.
Preferably, feeding square cylinder 2 comprises feed cylinder 21, discharge port 22 and horizontal agitator 23, and discharge port 22 is communicated with feed cylinder 21 and blanking barrel 3, and horizontal agitator 23 is arranged in feed cylinder 21.Feeding square cylinder 2 plays the effect of outputting material.
Operation principle of the present utility model is: 1, according to material formula, by the mixing of agitator some time, joins buffering bucket, wait for and enter extruder plastication after various material stirring is even.2, buffering bucket material relies on gravity to flow to middle and lower part and the feed cylinder of bucket, because space narrows extruding, the proportion of material is inconsistent, cause flow rate inconsistent, part heavy material material concentrates on bottom, and material is again uneven, and at this moment vertical stirring oar is started working, by the stirring movement up and down of material, material evenly enters screw rod transmission position secondary.3, the same direction of twin-screw work rotates, and material has own wt, and do not do rotation round motion with screw rod, by screw rod rotary squeezing, the formation that constantly travels forward delivers into extruding machine.
