Abstract

The invention specifically relates to a pre-loosing pull yarn tray used for an automatic doffer. The pull yarn tray comprises a baseplate (1), a skeleton plate (2), a gripping body (3), and an outer edge (4), wherein the skeleton plate (2) is arranged outside of the baseplate (1), the gripping body (3) is arranged outside of the skeleton plate (2), and the outer edge (4) is arranged outside of the gripping body (3); an engineering material adopted by the baseplate (1) is a phenol formaldehyde resin, an engineering material adopted by skeleton plate (2) is a polyurethane elastic body, an engineering material adopted by the gripping body (3) is solid silicone rubber, and an engineering material adopted by the outer edge (4) is a double layer spandex coating leather. The device enables the working process of the pull yarn of the doffer to be more exact and reliable, can greatly lighten and avoid damage on spun cotton and impulsion on a thread spinning spindle when the common type doffer pulls out yarn, expands the applicability of a moveable doffer, and realizes automatic control.

Description

technical field [0001] The invention belongs to a mobile doffing machine used for doffing of a ring spinning machine, and in particular relates to a pre-loosening and drawing disc used for an automatic doffer. Background technique [0002] my country's textile enterprises have long used manual doffing, and some manufacturers with high technical level use a mobile and simple auxiliary machine called "doffing trolley" to help workers complete the doffing process. This type of device has various types, simple structure, and low cost, but one of the main problems is that when spinning high-grade cotton yarn, the pre-drawing disc of rigid material will cause small damage to the cotton yarn, which needs to be improved and perfected urgently. The existing doffing machines of the same kind use traditional hard phenolic resin laminates or stainless steel plates to make the pre-loosening disc. damage. Contents of the invention [0003] The technical problem to be solved by the pre...
