套标机的刀盘机构的设计理念：

1、要使套标机速度达到400bpm以上，每0.15秒就要完成一次套标循环的动作，下标与切标电机必须频繁起停，定位精准。

2、切标电机旋转带动刀盘旋转一周完成切标动作，切标电机的定位不准会使刀盘过冲，最终导致刀盘堵标。

以上两点是设计刀盘时必须要注意的点：要想刀盘高速运转必须要考虑到刀盘装刀数量。设计一般刀盘我们都是以四把刀，六把刀为例。

例如四把刀的刀盘：

四把刀相对简单一点，安装和调试都比较简单。它是由四个轴承安装座连接着四根轴，轴上锁定同步轮然后呢有一条同步带，四个轴承安装座都安装在一块大板上，都是对角等分安装的。当然安装的距离都是由设计师按产品的大小高低而定的。同步带把四个同步轮连在一起，四个同步轮的大小要一样大。当然，旋转四个同步轮模拟动作的时候要把刀片装上去模拟，刀片一定不能碰到边上的的零件。

这里跟大家说一下要注意的地方，就是轴承座与轴配合要紧配，一般公差不能偏出0.01mm，否则配合太松会导致高速运转的时候，容易出现机械故障，切标不准等等的原因。

Design concept of cutter head mechanism of sleeve labeling machine:

1. In order to make the labeling machine speed above 400bpm, the labeling cycle must be completed every 0.15 seconds. The subscript and cutting motors must be started and stopped frequently, and the positioning is accurate.

2. The rotation of the cutting motor drives the cutter head to rotate for one week to complete the cutting operation. The inaccurate positioning of the cutting motor will cause the cutter head to overshoot and eventually cause the cutter head to block the label.

The above two points are the points that must be paid attention to when designing the cutter head: the high-speed operation of the cutter head must consider the number of cutters installed on the cutter head. We design four cutters and six cutters as examples.

For example, the cutter head of four knives:

The four knives are relatively simple, and installation and commissioning are relatively simple. It is connected to four shafts by four bearing mounts. The synchronous wheel is locked on the shaft and then there is a synchronous belt. The four bearing mounts are all mounted on a large plate and are installed equally and diagonally. Of course, the installation distance is determined by the designer according to the size of the product. The timing belt connects the four synchronization wheels together, and the four synchronization wheels must be the same size. Of course, when the four synchronous wheels are rotated to simulate the action, the blade must be installed to simulate, and the blade must not touch the parts on the side.

Here I want to tell you what to pay attention to, that is, the bearing seat and the shaft must be tightly matched, and the general tolerance must not deviate from 0.01mm, otherwise the too loose fit will cause high-speed operation, prone to mechanical failure, inaccurate cutting, etc the reason.
