纸盒成型机设计
摘 要
本文设计的粘贴式天地盖纸盒成型机，将已经经过剪裁和压痕的纸板进行一次性纸盒冲压成型。由于生产的纸盒尺寸可变，工作之前需要预先通过转动具有双向螺纹的长螺柱来调节纵向和横向弯板间的距离，一次纸盒成型过程分为几个时间阶段，主要是通过已设计好的不规则轮廓的大小凸轮以及成对的带轮和锥齿轮完成时间上的控制。纸板输送定位后，纸板随上可换冲头运动，先弯折带有纸舌两侧的纸板，然后进行纸舌弯折涂胶，最后进行另外两侧纸板的弯折同时与经过表面涂胶的纸舌粘贴，成型完成后纸盒随下可换冲压头在弹簧作用力下返回至成型初始位置，在进行下一张纸板输送的同时完成出料过程，通过协调各部分之间的运动时间关系完成在各个机构运动周期内的一次纸盒成型。
该机型为全机械设计，具有整体尺寸小、机能可靠、生产周期短、并能方便调节产品尺寸进行产品调整作业等优点，可以接入生产线流水作业，也能够进行单件少批量的生产，因此它对实际的生产具有很多现实意义。

Design of Carton Forming Machine
Abstract
In this paper the bonded paste covered carton former is designed through a disposable press forming of a clipped and creased cardboard. Due to the variable size of the production of the carton, time control should be achieved by turning the irregularly big and small cam which has a two-way screw and pairs of pulleys as well as bevel gears before the work begins. After the cardboard conveying is positioned, punch sport is brought on it, and first the cardboard with tongue paper on two sides is bended, then the tongue paper is folded and glued, finally the cardboard on the other two sides is folded, meanwhile stuck to the tongue paper glued on the surfa-
ce. After formed, the carton will return to the initial position under the spring force of the punch. The ejection of compact process is finished while the following cardboard is being conveyed. A long double-screw bolt lined in a carton in the motion cycle of each institute is used to adjust the distance between the vertical and horizontal bending cardboard through the coordination of the relationship between motion and time in different parts. A carton former process is divided into several time stages, mainly through the already designed type.
This type is a completely mechanical design, having many advangtages such as small size, reliable funct-
ion, and short production cycle as well as adjusting the product size conveniently for the operation adjustment. What’s more, it can not only join in the production line for line process, it can also undertake a small amount
of production for a single kind. Therefore it has a lot of practical significance to the actual production.
Key words: Carton former; bending cardboard; cam link mechanism; gear rack;bevel gear
2设计主要研究的内容
针对ZK660-A智能全自动天地盖纸盒成型机存在的不足以及其他大多数纸盒成型机械的最后成型环节大多采用手工生产，生产成本较高、质量不稳等问题，本课题拟设计一种方便实用的小型粘贴式天地盖纸盒成型机，用于简单纸盒的成型加工。能够方便调节纸盒成型机内部结构尺寸，生产不同规格尺寸的纸盒，并且生产周期较短，外观整体结构小，可以进行单件少量的生产，也可以接入生产线进行流水作业。
纸盒成型最小尺寸为100mm 100mm 30mm，最大尺寸为200mm 300mm 30mm。纸盒尺寸如图2-1。
