摘要:

针对现有丝绸生产流程长、工序多、效率低的问题,探索了通过借鉴先进络筒机的络交卷绕和张力控制等技术,将传统自动缫丝机进行升级改造。新型的筒子缫丝机保留了原缫丝线路的前部分,而将小竹或卷绕形式改造成单绪控制的筒子卷绕形式,同时选择合适的干燥方式,并在卷绕前依次增加了上油装置和超喂装置,通过变频技术实现络交卷绕装置与超喂装置的同步控制。结果表明:利用改造的缫丝机进行缫丝,可实现连续稳定的筒子缫丝;同时采用适当的工艺条件,其缫制的筒装丝性能与传统工序缫制的小竹或丝或筒装丝的性能相当,可满足后加工的要求。

Abstract:

For the problems of lengthy process, excessive processing steps and low efficiency in the existing silk production, a transformation of the widely used automatic silk reeling machine into a new type of automatic silk reeling machine for direct silk winding was explored by learning from the winding technology and the tension control of advanced winder. This new automatic reeling machine retained the front part of the silk reeling thread route of traditional automatic silk reeling machine, and the small reel for winding, however, was transformed into a single-thread-controlled bobbin for winding with a suitable drying method. An oiling device and an overfeeding device were added to the winding unit. The synchronous control of the winding unit and the overfeeding device was realized by the frequency conversion technology. When the silk was reeled using the transformed silk reeling machine, the results show that the silk can be wound continuously and stably on the bobbin, which has the same performance under suitable conditions with silks on small reels or on bobbin produced by traditional process and satisfies the requirements of post-processing.

Key words: direct bobbin winding, automatic silk reeling machine, tension control, overfeeding device, silk
