How to replace the blade of rubber and plastic mill

Zhengzhou Yuxi Environmental Protection Technology Co., Ltd. specializes in the production and manufacture of rubber-plastic pulverizers and PVC pelletizers. In the long-term processing of customers, the damage of the CNC blade is always a big problem for customers. Now people come to summarize the damage of the CNC blade How to solve it.

After the waste tire granulator machine has been used for a period of time, it is inevitable that some cutter heads will be damaged, so people should dismantle and replace the cutter heads at that time. Replacing the blade can ensure quality and yield. If the cutter head is not dismantled and replaced immediately, it will cause unevenness in the crushing of rubber and plastic, reducing the production volume and substandard crushing quality. Let me briefly explain how to replace the blade.

First of all, people have to cut off the switch power supply of the waste tire grinding mill. Safety is the top priority. When the cutter head is not sharp, people have to cut it. If the cutter head is not damaged, it is not necessary to use a high-purity graphite blade with cooking oil. The flat cutter head can be sharpened with a flat sand wheel, and finally sharpened with an edible oil stone. The angle of view of the cutter head should be less than 37°. When sharpening with a sand wheel, it is necessary to add refrigerant to avoid quenching of the cutting edge. If the blade damage is serious, you need to disassemble and replace the new cutter head, install and adjust the cutter head, adjust the aspect ratio of the cutting edge, and the tooth surface of the flat cutter head is exposed outside the disk. After the vertical aspect ratio is adjusted, it should be twisted after adjustment. Fix the anchor bolts of the knife to avoid the theme activities of the knife head and damage the equipment. For the adjustment of the fixed knife, the gap between the fixed knife and the movable knife should be adjusted to 1-2mm. After replacing the blade, we should check whether the bolts of each part are tightened. If they are loose, tighten them. Turn the pulley by hand. There should be no friction between the parts and the housing to ensure safety. After starting the machine, the feed can only be started when the machine is running at a normal speed. It is not allowed to start with materials. Do not throw the material deeply with your hands to avoid injury. If the machine makes abnormal noises during work, stop the tyre crushing machine for inspection and troubleshooting to avoid damage to the machine. Operators are not allowed to stand in the middle of the feed opening but should feed sideways to prevent accidents.
