接触式平动换卷薄膜收卷机设计

摘要收卷机属于缠绕机械的一个种类，在冶金、造纸印刷、化工化纤、纺织印染行业被广泛使用。当收卷对象为薄膜、纸张、布匹时，由于此类材料具有长度远大于宽度，宽度远大于厚度，且抗弯强度低的共同特点，所以往往也被称为柔幅材料收卷机。收卷机为柔幅材料运动提供动力并最终将其卷成符合要求的成品幅卷。在各种柔幅材料收卷中又以薄膜收卷最为复杂。9353
本文主要介绍了接触式平动换卷薄膜收卷机的设计，主要包括电机的选型，收卷机的结构设计，气动系统的设计。
电机的选型主要根据电机参数计算选择出合适的电机；收卷机的结构设计主要包括驱动辊的结构设计和平动换卷机构的结构设计；气动系统的的设计主要根据拨叉的摆动范围和压力要求选择合适的气压缸，并选用合适的气压压元件完成气压回路的设计。

TitleContact-type Translational Roll Alternation Winder Design
Abstract
Winder belongs to a class of winding machinery, metallurgy, paper printing, in chemical fiber and textile dyeing and printing industry is widely used. When the winding object for film, paper, cloth, because this kind of material has a length far outweigh the width, width far outweigh the thickness, and bending strength low common features, so often also known as soft picture material winder. Winder for soft materials to provide power movement of and ended its rolled into the finished product to meet the requirements of volume. In all kinds of soft material winding film winding most complex.
This paper mainly introduces the contact-type translational roll alternation winder design, including the selection of the motor and the winding machine structure design, pneumatic system design.
The motor of the selection of the main motor parameter calculation according to choose the right motor; Winder structure design includes drive roller structure design and reel changing organization structure design; Pneumatic system design main according to dial the swing range of fork to choose the appropriate air cylinder, and choose the right the pressure of the pressure element complete air pressure circuit design.
Keywords Winder Film winding Selection of the motor Winder structure design Pneumatic system
