Labtech实验室橡胶两辊开炼机

These rubber mills are distinguished from our other polymer mills by a more heavy duty build up of the rolls, bearings and Nip-Gap adjustment as well as a significantly larger drives where the rolls are directly coupled to heavy-duty helical bevel gears. This enables trouble free processing of even the toughest rubber compounds. The design and appearance of these rubber mills are the same as our other Scientific mills.

橡胶两辊开炼机由我们其他的聚合物两辊开炼设备发展而来，但是具有更坚固的结构设计，包括辊筒、轴承、间隙调整等部分。辊驱动直接连接于螺旋斜线齿轮装置实现，中间不经过任何传动消耗。这样最坚硬的橡胶制品也可以轻松开炼。

Modern designed steel cabinet built up with welded rectangular steel tubes. Swing away control panel mounted on a tubular steel arm. Heavy duty machined U-shaped frame for the roll assembly.

现代设计的柜式结构是由角钢焊接而成。摇臂式控制面板由管状钢架支撑。辊组件置于坚固的U型钢结构中。

Rolls machined from high-grade tool steel, which has been treated to a hardness of over 60 Rockwell C and hard chromed, precision ground as well as polished to a mirror surface. The rolls are mounted with dual heavy-duty bearings on each shaft and resting in machined bearing blocks. The grease lubricated bearing assemblies are built with special heat resistant seals on the roll sides to prevent leakage and to ensure a long bearing life at high temperature.

辊由高级工具钢制成，经过热处理，洛氏硬度超过60，并经镀铬和镜面抛光处理。辊经由双重坚固的轴承连杆置于轴承套中。油脂润滑的轴承组件，经过特殊的防热密封设计，可防止泄露并保证高热环境下的高使用寿命。

Central Nip Gap Adjustment with Digital Electronic Nip Gap instrument on the Control Panel for readouts in increments of 0,1 mm. Nip-Gap adjustable from 0,2 to 10,0 mm. Safety stops to avoid that the rolls touch each other. A hand wheel placed centrally below the roll U-frame adjusts the Nip-Gap. The hand wheel is linked to the front roll via heavy-duty gears so that the nip-gap can be easily adjusted even while running a heavy compound.

间隙调整数值会在控制面板显示，精度为0.1mm。调整范围从0.2mm到10.0mm。紧急制动装置确保两辊不会彼此接触。U型结构下的手轮用来调整间隙。手轮通过高坚固的齿轮连接到前辊，即便是开炼大量橡胶也可以轻松调节。

Water Cooling or optional oil heating/cooling of the Rolls where the water or oil flows in spiral channels near the roll surface which gives an extremely efficient cooling/heating of the rolls and the compound being milled. The cooling/heating media is connected to the rolls through rotary joints with ball bearing and carbon seals for a leak free operation.

水冷却或油加热/冷却方式，是通过贴近辊表面的螺旋型流道来实现的，保证强力的加热冷却效果。冷却/加热介质由旋转接头和辊连接，球轴承和密封圈保证不会泄漏。

Direct drive to the rolls with heavy-duty helical bevel gears where the output shaft is directly coupled to the roll shaft.

高坚固的螺旋斜线轴承直接驱动辊筒。输出轴直接连接辊轴，中间没有任何传动消耗。

Individual infinite variable speed drive of each roll with AC-motors coupled to programmable frequency inverters.

电机驱动方式为交流变频无极变速驱动。

Digital readout on control panel of roll torque in KN.

数字式显示装置显示当前辊的扭矩。

Speed variation of each roll by means of two potentiometers on the control cabinet.

控制面板上两个旋钮直接控制辊速度。

Synchronous speed variations of both rolls by means of a potentiometer on the control panel, which will regulate speed of both rolls simultaneously without changing the friction ratio between the rolls.

控制面板上还有同步变速装置，可同时改变两辊的速度而不改变摩擦比。

Swing open left and right side top cabinets with swing away control cabinet.

左右电气柜均为柔性方式连接，可轻松打开。

Non Touching and tiltable Split Type Bronze Side Platens. The side platens are split so that they follow the contour of the front roll when changing the Nip-Gap. The standard feature of tiltable side platens allows for fast and easy cleaning of the area facing the rolls.

同样还有非接触式铜质侧挡板。挡板被分割成两半，这样在改变间隙时可以包覆着辊面而相应运动。挡板可方便的清洁。

Bronze Scraping Knife with holders at front and rear part of the rolls.

辊前方和后面都有筒质刮刀。

Safety features according to European (CE) Safety Norms and other world standards, comprising of:  安全设计参照CE及其他世界安全标准，包括：

l         Protection cage over the rolls with interlocked swing open front and rear parts, which stop the rolls when opened.保护罩覆盖于辊筒之上，在打开时辊将停止转动。

l         Stop bar over the rolls which, when activated, will instantly stop the rolls.辊上方还有制动杆，按下时将立即停止辊转动。

l         Knee activated front and rear panels on the mills lower part, which instantly stop the rolls.电柜下部前后均有膝盖型制动装置，激活时可立即停止辊转动。

l         Interlocked Swing Open left and right top panels which stops the rolls and cuts of the electric supply when opened.左右电柜均有自锁装置，在打开时辊将停止转动并切断电源。

l         Interlocked rear cover to control panel, which cuts of the electric supply if the cover is removed.控制面板后盖带自锁装置，在打开时切断电源。

l         Safety main electric switch handle on the door to the electric cabinet, which cuts off the main supply before the door is opened. 电柜门把手联动电源开关，在门被打开时总电源被自动切断。
