DF-300多层纸复合机组滚压牵引部分设计
摘 要
本项目研制DF-300多层纸复合机组滚压牵引设计，适用于生产各种厚度的纸垫用纸．我们所研制的这套制纸机组可以降低劳动强度，提高自动化程度，以解决新型防渗漏纸垫用纸生产效率太低的问题．
总体设计思路：在驱动电机的驱动下，通过链传动使牵引滚辊子转动；滚压辊子通过气压缸提供压力把包装纸紧压在牵引辊上，并随着牵引辊一起转动，同时要保持牵引辊一定的温度，使纸垫纸保持干燥状态．
纸带在上胶后进行一次滚压牵引，通过气缸的压力压紧纸带，使它紧靠牵引轮上，牵引轮在链的带动下保持纸带恒定的速度，这样的辅助牵引滚压设置要每隔１.５米安置一套。在烘干后，即在切纸前，我们在这设置了主牵引滚压装置，主牵引轮在链的带动下匀速转动，为了增加摩擦力，我们在主牵引轮的光滑钢表面上加一层橡胶。为保证前面的烘干程度，我们在主牵引轮的里面通入热油。考虑到前面的轴承辊子等综合摩擦力，我们在这里安置了最大的牵引部分，在牵引轮的上下表面分别设置了一个滚压辊子，并且在每个滚压辊上的两头安置一对压紧气缸，通过杠杆的作用，把压力作用在牵引辊上，依靠摩擦力的作用牵引辊拖动纸带以一定的速度前进。
为了防止纸带的走偏，我们在烘干过程中设置了纠偏装置，纠偏装置在纸带的上方安置了一对并排放置的光电元件，两个光电元件左右相差２厘米，在光电元件的后头设置了一套纠偏的机械装置，以气压缸为驱动装置，气压缸通过接受光电元件的控制信号，推动支架前后摆动，又有杠杆在支架的支撑下带动纸带轮左右摆动才进而实现对纸带的纠偏。

Abstract
This project development DF-300 multilayer laminating paper rolling traction design, applicable to the production of thickness of the paper pad paper. We in this paper TaoZhi unit can reduce the labor intensity, increased a developed utomation, in order to solve the new leakage paper pad of paper production efficiency is too low.
The overall design ideas: the drive motor drive, through the chain that traction roll rotation roll; Rolling rolls through the air cylinder pressure to provide tightly compressed in traction wrapping paper roll, and roll with traction with rotation, and at the same time keep drawing roller a certain temperature, the paper pad of paper to keep dry condition.
After the glue tape in a rolling traction, through the pressure of the cylinder pressure paper tape, make it close to pulling rollers, traction wheel in the chain helped keep paper tape constant speed, the auxiliary traction rolling every 1.5 m set up to put a. In the drying, namely in the paper cutting before, we in this setting the Lord traction rolling device, the Lord traction in the chain wheel driven by rotation at a constant speed, in order to increase friction, we in the main pulling rollers on the surface of steel smooth add a layer of rubber. To ensure that the front drying degree, we in the main traction inside the wheel ventilation with hot oil. Consider to the front of the rolling bearing, and other comprehensive friction, we are here for the biggest drawing part, in traction round of the top and bottom surfaces were set up a rolling roll, and roll in each roller on the two for a pair of pressure cylinder head, through the role of leverage, and the pressure in traction roll role, rely on the role of the friction roller tape to certain traction drag speed.
In order to prevent the tape deviate, we during drying set the correction device, correction device in the upper part of the tape place for a pair of photoelectric element placed side by side, two photoelectric element are about 2 cm, in the back of the photoelectric element set up a set of rectification of machinery, air cylinder to for driving system, air cylinder by accepting photoelectric element control signals, and promote the stents to and fro, and leverage the support in the stents driving wheel swings around to tape and then realizing the rectification of tape.
