塑料粉碎机的维护内容及方法


1. 挡帘 Check apron 

观察档帘是否有更替的必要,视情况自行判定。避免造成回收料污染。

Observe whether the check apron needs to be replaced and determine according to specific situations. Avoid recycled material pollution.


2. 安全装置 Safety equipment 

1)启动粉碎机

Turn on the granulator 

2)松动安全开关的星形把手,直至安全开关完全分离

Loosen the star shaped handle of the safety switch until it completely falls apart

3)如粉碎机及时停机,说明安全装置功能正常。

If the granulator stopped promptly, then the safety equipment functions properly. 

注:如果安全开关分离后机器未能停机,请立刻手动停机(断掉主电源)并联系设备负责人。

Note: if it fails to shut down the machine by separating the safety switch, immediately perform manual shutdown (cut off the main power supply) and contact the person in charge. 


3. 电器元件 Electric components 

参照电器件连接部分,检查电器件所有线路是否松动脱落或损坏,有资格的工程人员可进行检查维修。

Refer to the electric Component Connection section, check all the circuit of electric components for loss or damage, qualified engineers can conduct inspection and maintenance. 


4. 润滑  Lubrication

   所有轴承均是终身免润滑的,不必加润滑油脂

All bearings are free of lubrication for lifetime, lubricating grease is not necessary. 


5. 传送带 Conveyor belt

如果是带有传送带装置的设备,For equipment with conveyor belt

1)请检查传送带的方向是否正确

check if the direction of the conveyor belt is correct 

2)检查输送带运动的直线度,如果皮带在运动过程中是倾斜的,先停止运转

如下图,打开端部盖板,调整调节螺丝C约1/4圈,再开机运转检查皮带的直线性,反复调节直到皮带运动的直线度满足要求不再倾斜。

Check the linear of belt movement, if it is oblique, then stop the equipment as shown in the following picture, repeat adjustment until the belt movement meet the requirements. 

注:皮带的直线性公差在1%,调节螺丝的扭力不能超过5N.M

Note: the linear tolerance of belt is 1%, the torque force of regulating screw should not exceed 5N.M


6. 清洁 Cleaning

1)对于使用过程中粉尘容易产生情况下的清洁,每天或至少每周需要清洁一次,轴承部分每天都需要用吸尘器清洁粉尘;

In case that dust is easy to be generated in use, it needs to be cleaned every day or at least once a week, the bearing part needs to be cleaned with vacuum cleaner every day. 

2)对于正常情况情况下的使用,每300小时需要需要清扫一次,轴承部分每周需要用吸尘器清洁一次。

For normal use, it needs to be cleaned every 300 hours, the bearing part needs to be cleaned with vacuum cleaner every week. 

3)轴承处的清理:见下图,用洗尘器进风管口对准排屑槽,旋转转子几圈即可。

Cleaning the bearing part: as shown below, face the inlet nozzle of vacuum to the chip removal groove, spin the rotor for a few circles.

注:轴承处粉尘的清理非常重要,虽然奥为有充分的防尘结构,但难免有少量粉尘进入,在高温下容易造成轴承的损坏。

Note: Cleaning the dust in the bearing part is very important, although Aowei has complete dust-proof structure, but it is inevitable that a small amount of dust entering, which may cause damages to the bearing at high temperature.  


7. 塑料粉碎机的动定刀 Rotating and fixed blades 

1)切削室的所有动定刀螺丝螺母均带螺纹紧固剂,在任何情况下均不能私自松动、加固、更换。

All the screw nuts of rotating and fixed blades in the cutting chamber are equipped with threaded fastening agent, it cannot be loosened, reinforced or replaced without permission under any circumstances.

2)动定刀间隙要定期检查,正确的间隙应该在0.15-0.25;

切忌使用刃口钝化的刀片,这样不紧造成机器的磨损,也造成能耗的损耗,也不能得到高品质的回收塑料粒子,动刀片要根据情况及时更换,定刀也要根据情况及时修磨或更换。

The gap between rotating and fixed blades should be regularly checked, proper gap should be 0.15-0.25. Do not use blades with passivated cutting edge, it will not only cause abrasion and loss of energy, but also make it hard to get high quality recycled plastic particles, rotating blades should be replaced according to the situation, fixed blades should be repaired or replaced as needed. 

3)在更换刀片的情况下,所有螺丝必须废弃掉,必须更换新的12.9级高强度螺丝,所有垫片,动定刀压块必须使用奥为生产或认可的部件。

When replacing blades, all the screws should be abandoned and replaced by 12.9 grade High-strength screws, all pads and briquetting of rotating and fixed blades should use parts produced or approved by Aowei. 

处理刀片的时候需要小心,它们很锋利,可能造成人身伤害。更换刀片的时候请戴上防护手套,以免割伤手指或手。

Be careful when dealing with the blades, they are sharp and may cause personal injury. Wear protective gloves when replacing blades so that they won’t cut your fingers or hands. 

4)转子本身容易转动,在更换刀片时候必须有木头块放置在切削中防止转子转动。

Rotator can be easily rotated, when replacing blades, place wood blocks in the cutting chamber to prevent the rotator from moving. 

5)动定刀螺丝拧紧扭力须按照下表规格进行安装:

Tightening torque of rotating and fixed blades should be installed according to the following specification:

8. 驱动皮带 Driving belt

1)手动旋转皮带轮几圈,检查皮带是否有裂口缝隙或边缘磨损,齿牙是否有破裂  

Manually rotate the belt pulley for a few times to check whether there are cracks, gaps or edge abrasion on the belt, whether there are cracks on the teeth 

2)在更换皮带或皮带轮的时候,务必调整皮带轮与电机驱动轮的平行度,保持皮带张力适中,皮带张力大小根据皮带规格有关。检测皮带张力可使用张力计测定。

When replacing the belt or belt pulley, adjust the depth of parallelism between the belt pulley and the driving wheel to ensure that the belt tension is moderate, the belt tension is relevant to the belt specification. Tensiometer can be used to measure the belt tension.
