塑料粉碎機(jī)篩網(wǎng)采用雙軸或單軸低速轉(zhuǎn)動，利用刀盤對物料進(jìn)行切、割、撕、拉。直連蝸輪蝸桿減速電機(jī)，直接安裝在破碎機(jī)主動軸上，通過齒輪變速傳至動軸，使主動軸的動刀與殼體上的靜止刀盤形成相對運(yùn)動。主動軸上的螺旋齒刀盤交錯(cuò)排列，使物料進(jìn)入后，同時(shí)受到擠、撕、剪的作用，從而使物料得到破碎。

Claw knife type plastic crusher screen adopts double axis or single axis at low speed, using cutter head to cut, cut, tear and pull material. Directly connected worm gear and worm reducer motor is directly installed on the driving shaft of the crusher and transmitted to the moving shaft through the gear speed change, so that the moving cutter of the driving shaft and the static cutter head on the shell form a relative movement. The spiral tooth cutter disc on the drive shaft is staggered, so that the material enters, and is squeezed, torn and shears at the same time, so that the material is broken.

由于所需斷碎的鐵濾網(wǎng)物料大多脆硬，因此破碎機(jī)內(nèi)片，小齒輪，篩網(wǎng)、刀片同等機(jī)件，必須是用耐磨損的堅(jiān)硬材料合金鋼制成。在主軸上裝有飛輪，以使主軸在破碎塑料時(shí)具有較大的扭矩。利用高速旋轉(zhuǎn)的葉輪將長的塑料攪撕折斷，高速旋轉(zhuǎn)的主軸上串聯(lián)著多片圓鋼板，圓板聯(lián)著主軸旋轉(zhuǎn)。圓板四周都裝有4~6個(gè)用錳鋼鑄成的小形齒輪。小齒輪在自己的小軸上自由地轉(zhuǎn)動。長而亂成團(tuán)的塑料從頂口進(jìn)入機(jī)內(nèi)，被高速轉(zhuǎn)動的鋼板上齒輪絞動，撕打成小碎塊，由底部的篩孔流出篩孔大小可根據(jù)塑料要求的斷碎顆粒大小而選定。

Because most of the broken iron filter material is brittle and hard, the crusher inner piece, pinion, screen mesh, blade and other parts must be made of wear-resistant hard material alloy steel. The flywheel is installed on the spindle to make the spindle have greater torque when breaking plastic. The long plastic is torn and broken by a high-speed rotating impeller. A number of circular steel plates are connected in series on the high-speed rotating spindle, and the circular plate is connected with the spindle to rotate. Four to six small cogs made of manganese steel are installed on all sides of the circular plate. The pinion turns freely on its own little shaft. Long and disordered plastic from the top mouth into the machine, is twisted by the high-speed rotating steel plate gear, torn into small pieces, from the bottom of the sieve hole out of the sieve size can be selected according to the plastic requirements of the size of broken particles.
