摘要：颗粒状糖果包装机设计是典型的机械系统设计，它不仅包括机构的尺寸、强度设计，还包括了传动机械系统设计。本设计主要是针对圆台柱状巧克力糖的铝箔纸包装。设计主要内容有三方面：设计方案设计、机械手及进出糖机构设计与传动系统链设计。
机械手及进出糖机构设计是本设计功能能否执行的灵魂，它也是本设计的设计重点之一。它要实现巧克力糖的输入、折边、抄底边、等等功能，直到最后由输送带输出。整个系统功能实现中，机械手要实现的是夹糖、折边、转送等重要功能，因此对机械手的形状、夹紧力及转位角度也提出了不同的设计要求，设计机械手时，也始终回绕着这几点进行。
传动系统设计，作为一个动作执行系统，动力是必不可少的，当然对动力的传递系统也就显得尤其重要了。系统功能中要实现机械手转位、送糖盘转位、供纸、剪纸、抄纸、接糖、顶糖及拨糖等功能，它们都需要不同大小的动力，这就需要传动系统的调节。如在机械手的转位功能中，为实现间歇的转位功能就得通过传动链中的槽轮机构来实现，该机构要保证机械手在转到位后，有一定的停留时间，从而为顶糖、接糖及拨糖功能的实现提供必要的机械动作执行时间。设计好的包装机机构正常的生产率为120r/min，且其生产率可在70～130r/min.

Abstract: The grain candy packer design is a typical machine system design. It not only included the organization's size, strength...etc. the design. And it still included the design of the transmission system. This design primarily aims at the circle pillar chocolates' aluminum foil packing. The design only contents contain three sides: Design project design, machine hand and I/O sugar mechanism design and the transmission system design.
It is Soul whether the function of the machine hand and I/O sugar mechanism’s design can carry out in this design. It is also one of the design points of this design. It wants to realize the importation, fold of the chocolates the sides, etc. the function. Until it finally be output by belt conveyer. In whole system function realizes, the machine hand realizes many important function, for example: clip the sugar, fold of the chocolates the sides, transfer...etc. Therefore to the shape of the machine hand, clip the tight dint and turn the angle also bring upped the different design request. When designed the machine hand, it is also proceeding with the center of these points.
System, motive is necessary. Certainly it is particularly important of the power transmission system. In the system function, it must realize moving the machine hand, moving the sugar dish, providing the paper, cutting paper, curling, connecting the sugar, crest the sugar and dialing the sugar etc. All these functions need the different power. It can be controlled with the transmission system. Such as the function of turning machine hand, for realizing a function of intermittent turning it needs the sheave of the transmission to regulate. After the machine turned the assurance position, the mechanism wants to have certainly stop over time, it can take enough time to crest sugar, connect the sugar and dial sugar. The transmission system still guaranteed the normal rate of production of packer to 120 r/ min .At the same time it can be controlled the rate of production at 70 ～ 130 r/ min.
Key words: Packer, chocolates packing, machine hand.
