新型塑料扁丝拉丝机

New-type Patented Plastic Flat Thread Extruding Machine

性能及特点

普通拉丝机在使用过程中，为了改变拉丝机拉伸线速度，都是通过更换链轮来实现的。由于链轮的大小都是固定的，这样更换链轮的方式非常影响工作效率，其中每个链轮更换后都是固定的速度，一个固定的速度就需要一个固定的链轮，无形当中提高了生产成本。同时这样的方式往往线速度不准确，线速度拉伸倍数无法提高编织丝的质量，而且还非常耗电。

我厂研发的新型电脑数控拉丝机组，牵伸比4-11，同时可自由变频精确调整拉伸比，无须更换链轮；同时本机的主控台可控制扁丝厚度，使生产过程中始终保持扁丝均匀的厚度，特别适用于生产吨袋、彩条布、水泥包装袋及化工袋等。该型机组可增加单丝拉力，整体提高产品质量档次。

本机组可利用*再生料、粉料或颗粒料拉制扁丝。挤出机的螺杆、机筒采用38CrMoAlA合金钢，经氮化处理，硬度达到HV950以上；挤出机的减速器采用20CrMnTi合金钢制造的硬齿面斜齿轮减速器，链轮采用45#中碳钢并经高温淬火处理，牵引辊筒电镀硬铬，牵引机构增加自控张力收卷辊筒；挤出机料筒、三通和膜头采用铸铝加热圈加热，经久耐用。

Performance and Characteristics

For a traditional extruding machine, it must change its chain wheel to change its drawing linear speed. However, the chain wheel’s size is fixed, which means one wheel stands for one speed. Users have to prepare different sizes of chain wheel for different speed. This causes low efficiency and high cost. For more, the speed is not accurate when changing by this way.

Now our new type extruding machine is adjustable for drawing ratio from 4 to 11, which is controllable and precise via free frequency conversion. It is no more necessary to change any chain wheel when changing its drawing speed. It’s an ideal machine for extruding plastic thread for making container sack, cement sack, chemical sack and so on.

  The machine can extruder flat thread directly by using * recycled material in powder or granular form. Its screw and cylinder are made of 38CrMoAlA alloy after nitriding treatment, the hardness of which is up to HV950 or above. The speed reducer uses hardened helical gear reducer made of 20CrMnTi alloy; the chain wheel is made of 45# quenched medium carbon steel. The drawing roller is electroplated with hard chrome; the drawing system is additionally equipped with tension controllable rewinding shaft; and the feeding drum, three-way pipe and die head adopts aluminum cast heater that’s durable in use.
