對薄而均勻組織片進行切制的機械,即為切片機。使用堅硬的石蠟或其他物質(zhì)對組織進行支持,每切一次切片厚度器向刀的方向推進所需距離。厚度器的梯度一般為1微米。對石蠟包埋的組織進行切制時,因為粘著前一張切片的蠟邊,而將切片的切片條制成多張。
A slicer is a machine for cutting thin and uniform tissue slices. Use hard paraffin or other materials to support the tissue, and push the thickness gauge to the required distance in the direction of the knife after each cut. The gradient of thickness gauge is generally 1 micron. When the paraffin embedded tissue is cut, because it adheres to the wax edge of the previous section, the slices are made into multiple slices.
使聚合物帶條切成顆粒的設(shè)備。導(dǎo)條板、喂入輥、加壓輥、旋轉(zhuǎn)刀盤共同構(gòu)成切片機。通過無級變速器傳動刀盤,由刀盤利用一組變換齒輪對喂入輥傳動。根據(jù)切粒尺寸,多把刀片裝配于刀盤上。對齒輪進行調(diào)換變換,能夠使切斷長度改變。
Equipment for pelleting polymer strips. The slicer is composed of a strip guide plate, a feeding roller, a pressure roller and a rotary cutter head. The cutter head is driven by CVT, and the feed roller is driven by the cutter head through a set of change gears. According to the grain size, more blades are assembled on the cutter head. The cutting length can be changed by changing gears.
對無級變速器進行調(diào)夠使帶條的惟入速度進行改變。切片是矩形或者圓柱形,大部分使用水下切粒機。其優(yōu)點是可以使得熔體或切片接觸空氣中氧得以避免,并且使切片光滑,使造粒中造成的粉末。
Adjusting the CVT can change the entry speed of the belt. Slicing is rectangular or cylindrical, most of the use of underwater granulator. The advantages of the method are that the melt or chip can avoid contacting oxygen in the air, the chip can be smooth, and the powder produced in granulation can be eliminated.
制漿造紙行業(yè):通常形式有刀盤式切片機,沉重的刀盤還起到飛輪的作用,使切片過程得以穩(wěn)定。
Pulp and paper industry: usually in the form of cutter head slicer, the heavy cutter head also acts as a flywheel to stabilize the slicing process.
沿盤面輻射狀安裝刀片,并且突出大約20毫米,原木由溜槽通過往轉(zhuǎn)盤的一側(cè)喂入,切片時,刀片和原木軸線成一定角度,處理量為290m3SUB/h,一般情況下,刀盤轉(zhuǎn)速為每分鐘249轉(zhuǎn),刀盤直徑為3360毫米,木片長度為24毫米,有16只刀片在刀盤上安裝,通過4臺馬達進行帶動,總功率為4×315千瓦,馬達速度為每分鐘25轉(zhuǎn)。
The blade is radially installed along the disk surface and protrudes about 20 mm. The logs are fed through the chute to one side of the turntable. When slicing, the blade is at a certain angle with the log axis, and the processing capacity is 290m3 sub / h. generally, the rotating speed of the cutterhead is 249 rpm, the diameter of the cutterhead is 3360 mm, and the length of the wood chip is 24 mm. There are 16 blades installed on the cutterhead, which are carried out by four motors The total power is 4 × 315 kW and the motor speed is 25 rpm.
對細(xì)胞或組織切片進行制作的機器。旋轉(zhuǎn)式和滑走式切片機應(yīng)用于光學(xué)顯微鏡,超薄切片機應(yīng)用于電子顯微鏡,超薄切片使用玻璃刀或鉆石刀進行制作。
A machine for making sections of cells or tissues. Rotary and sliding microtome are used in optical microscope, ultrathin microtome is used in electron microscope, ultrathin microtome is made with glass knife or diamond knife.
材料的裝置包括熱膨脹式以及機械推進式。冷凍切片機、低溫恒溫器以及冷凍超薄切片機應(yīng)用冷凍切片法。圓筒切片機應(yīng)用于徒手切片。
Material devices include thermal expansion and mechanical propulsion. Frozen slicing method was used in frozen slicer, cryostat and ultra-thin frozen slicer. Cylinder slicer is used for freehand slicing.
