倍速输送线是运用倍速链条的增速功能，使其上承托货物的工装板快速运行，通过阻挡器停止于相应的操作位置;或通过相应指令来完成积放动作及移行、转位、专线等功能。由于该机运送货物的台板需反复使用，所以很少单台使用，而是与各种专机如顶升平移机，顶升转位机等配套构成水平或垂直循环系统。它采用特制的，经表面处理的挤压铝合金型材作为导轨，使自流式输送系统在输送过程中具有非常好的稳定性和持久性，适合产品大批量连续生产。同时自流式输送系统灵活、多样化的设计使它具备多功能的特性。

所以自流式输送系统广泛地应用于各种电子电器、机电等行业生产线。倍速链流水线最常用的行业有：电脑显示器生产线、电脑主机生产线、笔记本电脑装配线、空调生产线、电视机装配线、微波炉装配线、打印机装配线、传真机装配线、音响功放生产线、发动机装配线。

Times the speed conveyor line is to use times speed chain growth function, supporting the goods on the tooling plate fast run, stop in the corresponding operation via the block position; Or by the movements of the corresponding instructions to complete the product put, migration and inversion,special line, etc. Counter to be repeatedly used to transport the goods due to the machine, so rarelysingle use, but with all kinds of special plane such as top dressing switching, jack-up transfer machine and other supporting form horizontal or vertical circulation system. It is made of a special, after surface treatment of aluminum profile extrusion as a guide, make the fluid conveying system in the process of transport has very good stability and durability, suitable for large quantities of continuous production. At the same time, since the fluid conveying system flexible, diverse design makes it has the multi-function features.

So since the streaming transmission system is widely used in various electronic, electrical andmechanical industry such as the production line. Times the line speed chain industry of the most commonly used are: computer monitors line, computer mainframe line, notebook computer assembly line, production line for air conditioning, TV assembly line, microwave oven assembly line, assembly line printer, fax machine assembly line, audio power amplifier, engine assembly line production line.
