Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of spinning equipment relates to a guide device for industrial yarn. BACKGROUND

[0002] Polyester filament is widely used in industry, which can be used as the skeleton material of tire cord, conveyor belt, cable covering, safety belt, plastic coated fabric, and also can be used for ropes, canvas, etc. The production and processing process of polyester filament is: chip - solid phase polymerization - screw extruder melting - melt pipeline - metering pump - spinning assembly - post heating - side blowing - oiling device - drafting and setting - main network - winding. The guide hook is needed to guide and fix the filament bundle between the processes.

[0003] In the production process of polyester industrial yarn, due to the production of many varieties, the fineness of the filament bundle is different, and there is a certain difference in the thickness of the filament bundle. If the same aperture guide hook is used in production, the tension of the filament bundle passing through the guide hook is not easy to control. Moreover, when the thickness of the filament bundle and the aperture are not matched, the friction of the filament bundle passing through the guide hook will produce white powder, and too much white powder will cover the broken filament detector and cause broken ends. At the same time, a layer of coking will be formed below the guide hook, producing loop yarn and other phenomena, which will affect the stability of the spinning condition.

[0004] At present, the aperture of the guide hook used in the production process is fixed, only the size is different, and when producing products with different fineness, only the large or small guide hook can be replaced, which cannot be adjusted and cannot be well matched with the produced varieties, which is easy to cause broken filament and loop yarn.

[0005] Patent CN202320832303.4 discloses a guide hook with adjustable angle, which uses linkage between rotating block, connecting rod and limiting shaft to adjust the angle of guide hook through rotating shaft sleeve and twisting adjusting bolt. Although it can reduce friction and white powder to some extent, it still cannot well control the angle when producing filament bundles with different thickness, and the aperture may not be matched.
