Automatic paper cutting machine using Geneva mechanism
ABSTRACT
使用日内瓦机制的切割机的设计对于以相等和准确的尺寸切割纸张非常有用。日内瓦驱动器是一种索引机制，可将连续运动转换为间歇性运动。由于间歇性运动，纸张在切割周期的时间间隔之间移动。然后，切割纸张是通过曲柄和杠杆机制来实现的。切割器将通过弹簧效果返回其原始位置。
This machine is also used to cut the various kind of paper products, plastic, thin film, leather, slice of nonferrous metal etc. This system can be applicable in paper cutting industry and proves how it can be a low cost solution in the production practice也可以看看：Paper Cutting And Rewinding Machine Mechanical Project
INTRODUCTION
Traditional hand lever cutting machine has drawbacks viz. it doesn’t provide safety to operator. It is not user friendly as every time user has to adjust the paper to desired cut position and hold the paper before taking cut. It is very time consuming and tedious process to take a job with different cut size so such machine also accuracy job taken on this machine depends on operators skills.
为了克服问题，设计了自动切割机，以减少标记和切割纸张的时间。
Geneva mechanism is commonly used indexing mechanism where an intermittent motion is required.
Geneva mechanism is commonly used indexing mechanism where an intermittent motion is required.
The conventional Geneva mechanism is generally simple and inexpensive. Because there is no special curved profile on any of the components except straight lines and circular arcs.
纸张切割是由曲柄和杠杆机制完成的。切割后，连接到切刀的弹簧将使切割机回到原始位置。
该机器的主要目的是减少标记论文的时间。因此，这台机器正在基于时机完全工作。它在书籍或笔记本中有广泛的应用区域
制造业，访问卡或标签制造业
etc.
Main Components Of Projects :
- 日内瓦轮：在我们的日内瓦，驱动的车轮有四个插槽，因此，对于驱动轮的每个旋转，驱动器的进展为90度。因此，360度的1/4度实现了间歇性运动。
- SPROCKETS:链轮或链轮轮是带有牙齿，齿轮甚至与链条融合的链轮的配置型轮。链轮用于通过滚子链之间的两个轴之间的电力传输。
- ROLLER CHAIN:Roller chain is the type of chain drive most commonly used for transmission of mechanical power between two sprockets. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket.
- 裁纸器：A paper cutter is a tool, designed to cut the paper with a straight edge. Paper cutters vary in size. This paper cutter is used as the oscillator in the four bar crank and lever mechanism.
- 线圈弹簧：线圈弹簧（也称为螺旋弹簧）是一种机械元素，通常用于存储能量并随后释放它。该线圈弹簧用于将切割器带到其原始位置。
- 轴：A shaft is a rotating machine element which is used to transmit power from one place to another. This shaft form an integral part of the machine itself. The crank shaft is an example of machine shaft.
- PAPER ROLLER:纸辊是一种间歇性运动时用于滚动纸的元素。纸辊用于喂养纸张而不会造成任何损坏。
工作原则
手柄固定在曲柄上（链轮）。如果手柄旋转，
1。When the cam pin is in extreme right position i.e. engage position, the crank shaft will be at extreme bottom position. Hence the cutter is in full open position and the spring will be in rest position.
2.When the cam pin is in extreme bottom position i.e. disengage position, the crank shaft will be at extreme left position. Hence the cutter is in partial cutting position and the spring will be in partial tension.
3.当凸轮引脚处于极端位置，即脱离位置时，曲柄轴将处于极端位置。因此，切割器处于完整的切割位置，弹簧将处于全部张力。4.当凸轮引脚处于极端位置，即脱离位置时，曲柄轴将处于极端位置。因此，切割器处于部分切割位置，弹簧将处于部分张力。因此，纸切割是通过上述日内瓦和切割器的四个过程来实现的。
优点：
1。No need for marking the paper.
2.它将减少标记纸张的时间。
3.纸的尺寸将是准确的。
4.Manufacturing cost is less.
5.没有噪声污染。
6.Compact in size.
7.可以用于小规模行业。
8.可以轻松更改机器元素
限制：
1。Can’t able to cut the papers above 15 cm width.
2.无法切割一堆论文，即超过5篇论文。
3.Can’t be used for large scale industries.
应用程序：
1.它能够在剪纸行业中使用。
2.它能够在纸制作中使用
3. It can be used in many small scale paper industries.
4.可以用来切割用于设计的颜色纸。
5.它可以用于固定商店。
