拉幅机装置及拉幅机装置内的异物除去方法以及溶液制膜设备
摘要：
本发明的针板拉幅机内的膜以两侧端部被针（72）及针板（73）担载的状态输送。针（72）及针板（73）在释放膜的担载时，被送至喷射风洗涤区域（83）。喷射风洗涤区域（83）中，针（72）及针板（73）被腔室（202）内覆盖。在腔室（202）内，对针（72）及针板（73）喷出喷射风。通过喷出该喷射风，将包含膜的添加剂经液化或固化而成的物质或者将针（72）插入到膜中时所产生的冲孔渣滓等的异物从针（72）及针板（73）上除去。异物介由抽吸喷嘴被排出至腔室（202）外。
摘要（英）：

In a pin tenter, a film is conveyed with both side ends thereof supported by pins (72) and pin plates (73). When the film is released from the pins (72) and the pin plates (73), the pins (72) and the pin plates (73) are delivered to a jet wind cleaning area (83). In the jet wind cleaning area (83), the pins (72) and the pin plates (73) are covered by a chamber (202). Jet wind is then directed against the pins (72) and the pin plates (73) in the chamber (202). This application of jet wind against the pins (72) and the pin plates (73) removes foreign substances from the pins (72) and the pin plates (73) such as liquefied or solidified film additives and punching scraps produced when the pins (72) are inserted into the film. The foreign substances are discharged from the chamber (202) through a suction nozzle.
