摘　　要：为解决某食用菌培养料包装袋袋口过长,不适用于栽培的问题,研制一种装配于自动装袋机中的热熔剪口装置,将曲柄轮的连续转动转化为切刀组带单侧停歇的正交往复运动。首先,阐述实现X向单侧停歇运动的凸轮-连杆机构设计过程,使用圆弧-过渡曲线-圆弧构造主要部件(槽形凸轮)的理论轮廓,为平滑连接2段圆弧,给出一种满足边界条件、运动规律和约束条件的三次B样条曲线算法设计过渡曲线;其次,设计控制Y向运动的主要部件(滚子轨道板)的形状、倾斜角度和分段特性;最后,给出装置的主要设计参数,并对其进行运动仿真与样机试验。结果表明,装置调试容易,运动过程平稳,满足自动化作业中耐高温塑料袋口熔断与切断的技术要求,剪口效率稳定在1000~1200袋/h。In order to solve the problem of too long mouth of bag for edible fungus culture material,which is not suitable for cultivation,a hot-melting cutting device which is assembled on automatic bagging machine was developed.The cutting device converts the continuous rotation of crank wheel to orthogonal reciprocating motion of the cutter group with unilateral stop.Firstly,the design process of cam-linkage mechanism for unilateral stop motion of X direction was described,an arc-transition curve-arc shape was used to construct the pitch curve of grooved cam which is the main component of the cutting device.A cubic B-spline curve algorithm which satisfies the boundary conditions,movement laws and constraints was presented to design the transition curve so that the two arcs could be connected smoothly.Secondly,the shape,slope angle and piecewise character of roller track board which is the main component of controlling Y direction were designed.Finally,the main design parameters of the device were given,and the motion simulation and the prototype tests were carried out.The results show that the device can be easily adjusted and move smoothly.The device meets the technical requirements of high temperature resistant plastic bag mouth fusing and cutting in practical operation.The cutting efficiency is kept at 1000~1200 bags/hour.
