毕业论文包装箱封口机设计说明书.doc

摘 要 本次课题设计的是折盖封箱机，采用两侧皮带驱动来进行折盖封箱的方案，上下封箱、经济、快速、平稳。这种方案在技术上是相当成熟的一种，它被广泛应用于生产实际中。这次设计的折盖封箱机，可以根据纸箱规格，手动调节宽度及高度，可单机作业，也可与 HYPERLINK /offer/post/fill_product_info.htm?offer_id=190784671operator=edit \t _blank 自动化 HYPERLINK /offer/post/fill_product_info.htm?offer_id=190784671operator=edit \t _blank 包装流水线配套使用。工作时，当箱体进入工作空间后，由光电开光控制推杆使折盖机构折合箱体，当箱体运行至刀架位置时，箱体将刀架和前胶带压轮压退位，而后胶带压轮在四杆机构的作用下与前胶带压轮保持同步运动而退位，并使前面的胶带与纸箱贴合并封箱。随着箱体前进，胶带不断地抽出封在箱体上。当箱体的后部离开刀架时，前胶带压轮由于四杆机构的作用与后胶带压轮的运动一致，而刀架受弹簧弹力作用，复位弹起，切断胶带。当箱体运动至离开后胶带压轮时，后胶带压轮也由于受可调弹簧回位作用而复位，使连在箱体上最后的胶带也贴在箱体上，完成后段封箱任务。该论文详细说明了本次封箱机设计的步骤及其依据。包括设计方案的选择、折盖机构的设计、电机的选择、工作台部件的设计、顶式部件设计和刀片的设计。 关键词：折盖封箱机；折盖机构；四杆机构；刀架部件；刀片设计  Abstract The packing box sealing machine that this subject is designed, adopt both sides belt to drive to carry on the scheme of a box, seal the box, economy, fast, steady up and down. This kind of scheme is applied to producing in reality extensively, is a quite ripe one technically. The packing box sealing machine designed this time, can regulate width and height by hand,according to the carton specification, but unit homework, can also pack the assembly line to use with automation tegether. Work, when the box into the working space, the box at the side of the toothed belts advance under friction. When run to the turret position, box blade frame and pressure roller pressure to step down before the tape, but after the knife and tape roller in the role of four-bar mechanism with a tape roller under the synchronized movement to abdicate, and to front .The tape and carton sealing paste the merger. With the advance box, tape keep out letters in the box on. When the box from the back of the blade, the first tape roller as the role of four-bar linkage with the movement of the roller after the tape line, the blade holder by a small spring elastic effect reset the bounce and cut tape. When the cabinet after the departure of tape roller sports, the post-tape roller is also adjustable spring back due to the role of the reset bi
