摘 要
本设计主要介绍了锯齿状塑料破碎机的发展历史、工作原理和设计过程。基于对塑料炭行业的分析和近期塑料炭行业的背景,以及锯齿塑料破碎机存在的问题和不足,我们制定了塑料炭行业的使用方案设计。
本设计采用单电机驱动方式,电机轴接皮带传动,大皮带轮接单级减速机输入轴。减速机的输出轴与主动齿轮滚轴连接,扭矩通过同步齿轮传动传递到从动齿轮滚轴。本次设计的主要设计内容包括单级减速机、皮带传动、一对同步齿轮、齿辊盘和齿辊轴的设计。由于整个传动系统比较简单,保证了传动的稳定性。考虑到牙科塑料研磨机存在的一些问题,本次设计还增加了一些改进措施。磨盘上装有磨锥,以提高磨辊齿的磨削效果,减少粉尘过多的现象。装有弹簧回缩安全装置,能很好地补偿散状物料进入破碎箱时齿辊的位移,防止破碎辊被铁屑损坏。

ABSTRACT
This design mainly introduces the development history, working principle and design process of the zigzag plastic crusher. Based on the analysis of the coal industry and the recent background of the coal industry, and the problems and deficiencies of the sawtooth plastic crusher, we have formulated the use plan design of the coal industry.
The design adopts single motor drive mode, motor shaft to belt drive, large pulley to single stage reducer input shaft. The output shaft of the reducer is connected to the active gear roller, and the torque is passed through the synchronous gear drive to the driven gear roller. The main design contents of this design include a single-stage reducer, belt drive, a pair of synchronous gear, tooth roller disc and tooth roller shaft design. Because the whole transmission system is relatively simple, the transmission stability is guaranteed. Considering some problems with the dental plastic grinder, some improvements were added to this design. The grinding plate is equipped with a grinding cone to improve the grinding effect and reduce excessive dust. The spring retraction safety device can well compensate for the displacement of the tooth roll when the scattered material enters the crushing box to prevent the broken roll from being damaged by iron chips.
