三．进料装置
3. feeding device
进料装置是保证物料能均匀,定量地进入压力区,并使物料受到良好挤压的一个重要装置。在工作中,物料始终充满整个进料装置,由其导向进入磨辊的压力区。
The feeding device is an important device to ensure that the materials can enter the pressure zone uniformly and quantitatively, and make the materials well squeezed. During work, the material always fills the entire feeding device and is guided by it into the pressure zone of the grinding roller.
进料装置由进料筒、闸板、下侧板、支架、丝杆、连杠、电机减速机等组成，详见进料装置装配随机部件图。
The feeding device is composed of the feeding tube, gate plate, the lower side plate, support, screw rod, connecting rod, and motor reducer. For details, please refer to the random parts assembly drawing of the feeding device.
在侧挡板的下端,既在压力区的磨损严重部位设置了高硬度的硬质合金材料。这样可以减小磨损,提高被挤压物料的挤压质量。
At the lower end of the side baffle, the high-hardness cemented carbide material is set in the severely worn parts of the pressure zone. This can reduce wear and improve the extrusion quality of the material being extruded.

The lever-type energy-saving feeding device composed of gate plate, screw rod, connecting rod, and motor reducer. The screw rod is controlled by the motor reducer, and the opening of the gate is controlled by the connecting rod, so as to achieve the effect of controlling the processing capacity. .
侧板顶紧装置用以控制侧挡板与磨辊端面的间隙,该装置是由支架、顶紧螺杆、蝶形弹簧及弹簧座等组成。
The side plate tightening device is used to control the gap between the side baffle plate and the end surface of the grinding roller. The device is composed of bracket, tightening screw, butterfly spring and spring seat.
通过顶紧螺杆可以调节侧挡板下端位置与磨辊端面的间隙。调节压板可以对蝶形弹簧的顶紧力作调整,使侧挡板在正常工作时保证与磨辊端面有适当的间隙,减小磨辊端面的漏料。
The gap between the lower end of the side baffle and the end surface of the grinding roller can be adjusted by tightening the screw. The adjusting pressure plate can adjust the tightening force of the butterfly spring, so that the side baffle can ensure a proper gap with the end face of the grinding roller during normal operation, and reduce the material leakage of the end face of the grinding roller.
四．主电机和传动系统
4. main motor and driving system
主电机是整套辊压机主动力源。采用两台高压三相异步电动机,用户可自购或委托制造商配套。
The main motor is the main power source of the complete roller press. Two high-voltage three-phase asynchronous motors are used, which can be purchased by the user or commissioned by the manufacturer.
传动系统采用国际上先进的行星减速器悬挂传动装置。通过缩套联轴器将行星减速器的输出轴刚性地固定在磨辊主轴上(见主轴联接图)。减速器的安装定位基础为磨辊主轴,并且减速器可以随主轴作水平移动。减速器的输出扭矩,由扭矩支承装置(见扭矩支承装置示意图)来平衡。扭矩支承包括一个四连杆机构和一个弹性系统。该扭矩支承可以满足活动辊的水平移动,同时起到均载、吸振和缓冲的作用,可以使加工、安装精度降低。四连杆机构中的所有铰接点均采用带密封圈的关节轴承,适应性强。弹性系统中的弹性元件采用具有轴向尺寸小,刚度系数大的蝶形弹簧。在设备工作中,可以通过调整装置,调节其弹簧的顶紧力,使弹性系统适应设备负载的状况,主电机与行星减速器之间使用万向节传动轴联接。由于该万向节传动轴设置在高速端,使其本身所需传递的扭矩相对较小,转速高。并且所用的十字轴万向节传动轴具有传动效力高、传递扭矩大、传动平稳、润滑条件好、节点倾角大等特点。
The driving system adopts the international advanced planetary reducer suspension driving device. The output shaft of the planetary reducer is rigidly fixed on the main shaft of the grinding roller through the shrink sleeve coupling (see the main shaft connection drawing). The installation and positioning basis of the reducer is the grinding roller main shaft, and the reducer can move horizontally with the main shaft. The output torque of the reducer is balanced by the torque support device (see the schematic drawing of the torque support device). The torque support includes one four-bar linkage and an elastic system. The torque support can meet the horizontal movement of the movable roller, and at the same time has the functions of load balancing, vibration absorption and buffering, and can reduce the processing and installation accuracy. All articulation points in the four-bar linkage mechanism adopt joint bearings with sealing rings, which is highly adaptable. The elastic element in the elastic system adopts butterfly springs with small axial size and large stiffness coefficient. In the equipment work, the tensioning force of the spring can be adjusted by the adjusting device, so that the elastic system can adapt to the condition of the equipment load. The main motor and the planetary reducer are connected by the universal joint drive shaft. Because the universal joint drive shaft is arranged at the high-speed end, the torque required to transmit by itself is relatively small and the speed is high. And the cross-shaft universal joint drive shaft used has the characteristics of high driving efficiency, large transmission torque, smooth transmission, good lubrication conditions, and large node inclination.
传动系统中所用到的缩套联轴器为一非标配套件,它由圆锥缩套、两个收缩盘,高强度螺栓组和防尘圈等组成。其工作原理是:拧紧高强度螺栓,使圆锥缩套紧压减速器的中空轴,并使其发生弹性变形,紧抱在磨辊主轴轴颈上,利用其间正压力所产生的磨擦力来起到传递扭矩和减速器定位的功能。
The shrink sleeve coupling used in the driving system is the non-standard accessory. It consists of the round tapered shrink sleeve, two shrink disks, the high-strength bolt group and the dust ring. Its working principle is: Tighten the high-strength bolts to make the round tapered shrink sleeve compress the hollow shaft of the reducer, and make it elastically deform, tightly hug the main shaft journal of the grinding roller, and the friction force generated by the positive pressure is used to transmit torque and reducer positioning.
五．液压系统
5. hydraulic system
液压系统是为磨辊提供所需的挤压粉碎力而设置的,其主要作用是液压弹簧,兼有液压保护功能。它的性能直接影响到挤压粉碎物料的质量和设备的安全。
The hydraulic system is set up to provide the required squeezing and crushing force for the grinding roller. Its main function is hydraulic spring, which also has hydraulic protection function. Its performance directly affects the quality of crushed materials and the safety of equipment.
该系统由泵站,阀台和油缸三大部分组成(见液压系统图)。油缸直接安装在机架上，阀台、泵站集成在油箱上，然后通过管路连接起来。
The system consists of three parts: pump station, valve table and oil cylinder (see hydraulic system drawing). The oil cylinder is directly installed on the frame, and the valve table and pump station are integrated on the oil tank, and then connected by pipelines.
泵站是提供液压油泵,主要由油泵、油泵电机、溢流阀、压力表及滤油器等组成。该泵站的滤油器与加压主油路串联布置,使液压油经过滤油器过滤后进入主油路,以避免因杂质进入主油路可能造成的系统元件的堵塞、系统压力可根据操作需要无级调节。可无级调节控制系统所需的压力。滤油器上附有压差发讯装置,当滤油器滤筒堵塞,两边压差达到一定值时发出报警信号,通知操作人员清洗或更换滤筒。阀台部分是液压系统的主油路和控制油路,由两只大容量蓄能器和电磁溢流阀等组成。在工作时,四只主油缸通过大直径管路与两只蓄能器相连通,使得它们之间的压力始终相同,油缸的动态特性灵敏,流量大的特点,磨辊间一旦进入异物,系统压力升高时,它能及时打开卸压,保护主机设备。该溢流阀即可液控,又可电控。在调试和处理意外事故时,可以按动电钮卸压或调整压力。阀台上另设置有压力传感器和电接点压力表。可以通过压力传感器,将压力系统压力信号输给主控制室和控制柜,与主机联锁,也便于操作人员观察操作。电接点压力表主要是控制液压系统压力的上、下限。控制泵站油泵电机的启闭。
The pumping station provides hydraulic oil pumps, which are mainly composed of oil pumps, oil pump motors, overflow valves, pressure gauges and oil filters. The oil filter of the pump station is arranged in series with the pressurized main oil circuit, so that the hydraulic oil enters the main oil circuit after being filtered by the oil filter. In order to avoid the blockage of system components that may be caused by impurities entering the main oil circuit, the system pressure can be steplessly adjusted according to operation needs. The pressure required by the control system can be steplessly adjusted. The oil filter is equipped with the pressure difference signaling device. When the oil filter cartridge is blocked and the pressure difference on both sides reaches a certain value, an alarm signal will be issued to notify the operator to clean or replace the filter cartridge. The valve table is the main oil circuit and control oil circuit of the hydraulic system, which is composed of two large-capacity accumulators and an electromagnetic overflow valve. When working, the four main cylinders are connected to the two accumulators through large-diameter pipelines, so that the pressure between them is always the same. The dynamic characteristics of the cylinders are sensitive and the flow rate is large. Once foreign matter enters the grinding roller room, when the system pressure rises, it can open the pressure relief in time to protect the main equipment. The overflow valve can be controlled hydraulically and electrically. When debugging and handling accidents, you can press the button to relieve or adjust the pressure. The pressure sensor and the electric contact pressure gauge are additionally arranged on the valve table. The pressure signal of the pressure system can be transmitted to the main control room and the control cabinet through the pressure sensor, and it is interlocked with the main machine, which is also convenient for the operator to observe and operate. The electric contact pressure gauge mainly controls the upper and lower limits of the hydraulic system pressure. Control the opening and closing of the oil pump motor of the pump station.
四只油缸直接作用于活动辊轴承座上,为磨辊提供适当的挤压粉碎力。油缸作用力可通过油路控制系统的转换使其作用于单边轴承座或双边轴承座,当磨辊分边动作时,由位移传感器对两轴承座的水平位移进行检测控制。油缸由缸体、活塞、端盖、耐磨环和密封圈组成。见油缸装配示意图,该油缸为双作用缸,这样一旦设备的进料系统发生故障。可以及时用油缸将活动辊拉回,增大辊隙,排除故障。
The four oil cylinders directly act on the bearing seat of the movable roller to provide proper crushing force for the grinding roller. The force of the oil cylinder can act on the single-sided bearing seat or the double-sided bearing seat through the conversion of the oil circuit control system. When the grinding roller is separated, the horizontal displacement of the two bearing seats is detected and controlled by the displacement sensor. The oil cylinder is composed of cylinder body, piston, end cover, wear ring and sealing ring. See the cylinder assembly drawing, the cylinder is the double-acting cylinder, so that once the equipment's feeding system fails, the movable roller can be pulled back with the oil cylinder in time to increase the gap and eliminate the fault.
在油缸活塞杆的端面,设置了一环面压头,以防止因移动辊轴线偏斜时,给液压缸附加径向载荷。
An annular pressure head is arranged on the end surface of the piston rod of the oil cylinder to prevent additional radial load to the hydraulic cylinder when the axis of the moving roller is deflected.
