①PVC膜压纹机主要利用在两个待焊工件接触面所产生的摩擦热能来使塑料熔化。热能来自一定压力下,一个工件在另一个表面以一定的位移或振幅往复的移动。一旦达到预期的热合程度,振动就会停止,同时仍旧会有一定的压力施加于两个工件上,使刚刚热合好的部分冷却、固化,从而形成紧密地结合。
(1) PVC film embossing machine mainly uses the friction heat energy produced at the contact surface of two workpieces to be welded to melt the plastics. Thermal energy comes from the reciprocating movement of one workpiece on another surface with a certain displacement or amplitude under a certain pressure. Once the desired degree of thermal bonding is achieved, the vibration will stop, and at the same time, there will still be a certain pressure applied to the two workpieces, so that the part just heated can be cooled and cured, thus forming a close bond.
②PVC膜压纹机另一种方式是利用高频热能热合的方法。PVC膜压纹机在进行轨道式振动摩擦热合时,上部的工件以固定的速度进行轨道运动——向各个方向的圆周运动。运动可以产生热能,使两个塑料件的热合部分达到熔点。一旦塑料开始熔化,运动就停止,两个工件的热合部分将凝固并牢牢的连接在一起。小的夹持力会导致工件产生小程度的变形,高周波瞬间热合,加热,通过高频一次焊接热合成功。
(2) Another way of PVC film embossing machine is to use high frequency thermal energy to heat up. When the PVC film embossing machine is in track vibration friction thermal closure, the upper part of the workpiece moves in orbit at a fixed speed - circular motion in all directions. Motion can generate heat energy, so that the hot-bonded parts of two plastic parts reach the melting point. Once the plastic begins to melt, the movement stops, and the heat-bonding parts of the two workpieces will solidify and firmly connect. Small clamping force will lead to a small degree of deformation of the workpiece, high cycle instantaneous thermal closure, heating, through a high frequency welding thermal synthesis work.
