三辊研磨机主要用于研磨各种油漆、油墨、油彩颜料、食品、化妆品及牙膏等膏状浆料之用,为油漆、油墨等工厂研细膏状浆料的主要设备。

The three-roller grinder is mainly used for grinding various pastes such as paints, inks, oil paints, foods, cosmetics and toothpaste. It is the main equipment for researching fine pastes in paint and ink factories.

 

三辊研磨机工作原理

通过机器水平方向排列的三根辊筒的表面相互挤扎及不同速度的摩擦而达到研磨作用,研磨物料一般只要研磨二次就可以达到要求,难研物料必须研磨多次,方能达到要求,后的加工细度一般可达到3~18µm左右(用细度刮板测定)。

工作时将快、慢辊调节到适当位置,启动机器,然后将需研磨的浆料加入中辊与慢辊之间铜刀处,浆料经过中、慢辊表面挤扎后,由中辊带给快辊,再由紧贴表面的出料刮刀予以刮下,通过装有拦板的刀板,流入盛料桶,由此构成整个研磨过程。

Three-roller grinding machine works:

The grinding effect is achieved by the surface of the three rollers arranged in the horizontal direction of the machine being squeezed against each other and friction at different speeds. Generally, the grinding material can meet the requirements as long as it is ground twice. The processing fineness can generally reach about 3 ~ 18µm (determined with a fineness scraper).

Adjust the fast and slow rolls to the proper position during work, start the machine, and then add the slurry to be ground to the copper knife between the middle and slow rolls. The fast roller is scraped off by the discharge scraper that is close to the surface, and then flows into the bucket through the blade equipped with the blocking plate, thereby constituting the entire grinding process.

三辊研磨机机器结构

★机器部分

机体采用铸件,由机座和上盖板组成,机体左右导轨面上按水平方向装有双列向心球面辊子轴承的慢、中、快轴承座每边各一只,并与上压板连接在一起,中辊轴承座用螺栓连接机体,快、慢辊轴承座由一对齿轮转动带动螺杆旋转作用,作前后移动,轴承座用于支撑慢、中、快三辊筒,辊筒轴的右端装有冷却水管及水箱,左端装置为传动齿轮箱,其机体下部里面装有电动机、慢辊与中辊之间两旁按辊筒中间的垂直下方装有加料用的铜刀,快辊前方紧靠辊筒表面装有出料用的刀片部件,由此组成三辊研磨机。

★传动部件

机座下部装有电动机,通过三角胶带传动,传入快辊,由快辊通过齿轮传动至中辊,中辊再传至慢辊。

★辊筒

辊筒分为快、中、慢各一,均冷硬合金离心浇铸而成,两端为经热处理的优质钢轴头,左轴头装有传动齿轮,右轴头中间通孔为水道孔作为辊筒在工作时冷却用。辊筒的硬层厚度不小于15mm,其硬度不低于肖氏硬度70,表面经精密磨削。

★进料装置

进料装置由铜刀和铜刀支架组成,安装在慢辊与中辊之间的两端,刀圆弧紧贴在慢、中辊两辊表面,保证不流物料,铜刀支架采用螺栓固定在机体上,便于调整边距及拆装清洗,铜刀应经常进行调整,务便于辊筒表面密贴。

★冷却装置

为适当地消除辊筒工作面因磨擦后产生的热膨胀影响辊筒接触面的平整,在辊筒右轴头处装有冷却水管,在水管接头处套有橡胶管,通入水源经辊筒内壁热交换后,由原孔回入水箱,流入下水道。

★出料装置

供出料用的出料板装于机体的出料板支架上,出料板上装有刀片,通过出料板调节螺钉,使刀片紧贴在快辊表面上,刀口的贴合位置应高于辊筒中间5 mm,便于顺利地刮下经磨细后附着在快辊表面上的物料。

★压力调整装置

转动手轮,经齿轮螺杆与螺帽的作用,促使快、慢辊沿导轨作前后移动,以调节浆料的研磨细度。

Three-roller grinder machine structure:

★ machine part

The machine body is made of castings, consisting of a machine base and an upper cover plate. The left and right guide surfaces of the machine body are equipped with two rows of slow, medium and fast bearing seats on each side of the slow, medium and fast bearing seats in the horizontal direction, and are connected to the upper pressure plate. Together, the middle roller bearing seat is connected to the body with bolts. The fast and slow roller bearing seat is driven by a pair of gears to drive the screw to rotate forward and backward. The bearing seat is used to support the slow, medium and fast three rollers, and the right end of the roller shaft. It is equipped with a cooling water pipe and a water tank, and the left end device is a transmission gear box. The lower part of the body is equipped with a motor, a slow roll and a middle roll. The surface of the roller is equipped with a blade member for discharging, thereby forming a three-roll mill.

★ Transmission parts

The lower part of the machine base is equipped with a motor, which is transmitted to the fast roller through the V-belt. The fast roller is transmitted to the middle roller through the gear, and the middle roller is then transmitted to the slow roller.

★ Roller

The rollers are divided into fast, medium and slow ones, all of which are made of centrifugal casting of cold-hard alloy. Both ends are heat-treated high-quality steel shaft heads. The roller is used for cooling during work. The hard layer thickness of the roller is not less than 15mm, its hardness is not less than 70 Shore hardness, and the surface is precision ground.

★ Feeding device

The feeding device is composed of a copper knife and a copper knife holder. It is installed at the two ends between the slow roller and the middle roller. On the machine body, it is easy to adjust the margins, as well as to disassemble, clean and clean. The copper knife should be adjusted often to make the surface of the rollers stick.

★ Cooling device

In order to properly eliminate the flatness of the roller contact surface due to the thermal expansion of the working surface of the roller due to friction, a cooling water pipe is installed at the right axis of the roller, a rubber tube is sleeved at the water pipe joint, and the water is passed through the inner wall of the roller. After the heat exchange, it returns to the water tank from the original hole and flows into the sewer.

★ Discharging device

The discharge plate for discharging is installed on the discharge plate bracket of the machine body. A blade is installed on the discharge plate. The blade is adjusted to fasten the surface of the fast roller through the adjustment screw of the discharge plate. The position of the knife edge should be higher than the roller. The middle of the barrel is 5 mm, which makes it easy to scrape off the finely adhered material on the surface of the fast roller.

★ Pressure adjustment device

Rotate the hand wheel, through the action of the gear screw and nut, to promote the fast and slow rollers to move back and forth along the guide rail to adjust the grinding fineness of the slurry.

Three-roller mill operating procedures

★ Check whether the position and locking of each component is normal. Fill in the lubricating oil according to the points shown in the figure and turn on the power.

★ Adjust the left and right handwheels, and observe whether the roll linkage is normal.

★ Remove the dirt on the roller surface: Wipe with soft paper or clean cotton yarn, loosen the handle

★ Adjust the gap between the front and rear rollers and the middle roller to 0.5 mm, then start the power supply to idle for 1-2 minutes.

★ After starting the operation, adjust the gap between the middle and the last two rollers to 0.3 mm, press the baffle plate, add slurry appropriately, visually inspect the coloring depth, fine-tune the rear roller to make the color uniformly cover the rollers, and lock the fixing nut.

★ Adjust the hand roller of the front roller at the same time with both hands to make the front roller slowly contact the middle roller. The surface of the current roller is evenly colored, then lock the fixing nut, and then adjust the angle of the material plate to make it light.

Press on the roller surface, the slurry can be discharged uniformly. Check the uniformity of the discharge and the particle size of the finished product, and continue to fine-tune the front and rear rollers until the finished product reaches the predetermined size. The blade scraper should be returned in time before and after.

★ Remove the paint and wash it in time. Wipe the test roller and related parts, loosen the scraper and the blocking plate, apply a small amount of oil, and then cover it with wax paper to protect it.
