Oiling device for short fiber postprocessing

Abstract

The invention belongs to the technical field of chemical fiber production equipment and discloses an oiling device for short fiber postprocessing. The oiling device comprises a frame, an oil collectorlifting mechanism, an oil collector, an oil spraying tank, an oil gathering roller, an oil gathering roller driving motor, an oil pumping mechanism and a pressure air introduction mechanism. The frame comprises a base and a longitudinal plate; the oil collector lifting mechanism is arranged on the base; the oil collector is connected with the oil collector lifting mechanism; the left end of the oil spraying tank is fixed to the upper portion of the longitudinal plate, the right end of the oil spraying tank is correspondingly positioned above the oil collector in a horizontal cantilever state,the upper portion of the oil spraying tank is provided with an oil spraying tank cover, and the lower portion of the oil spraying tank is provided with an oil spraying hole; the oil gathering rolleris arranged in a cavity of the oil spraying tank, and the left end of the oil gathering roller is supported on a left wall of the oil spraying tank while the right end is supported on the right wall of the oil spraying tank; the oil gathering roller driving motor is fixed to the upper portion of the longitudinal plate and connected with the oil gathering roller; the oil pumping mechanism is arranged at the left end of the oil spraying tank cover and communicated with the cavity of the oil spraying tank; the pressure air introduction mechanism is in pipeline connection with the oil spraying tank cover and communicated with the cavity of the oil spraying tank. Convenience in yarn penetrating is achieved, the requirement of regulation in fiber bundle fiber material changes is met, and uniformoiling effects of fiber bundles are achieved.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber production equipment, and in particular relates to an oiling device for short fiber post-processing. Background technique [0002] As known in the industry, hot water is needed to heat the tow during the post-processing and stretching of short fibers (that is, chemical fiber staple fibers) so as to facilitate fiber stretching. When the fibers are stretched in a hot water bath, the The oil agent is dissolved in hot water, so it needs to be oiled again after the fiber comes out of the hot water bath, and can be dried after oiling again. This oiling process is usually called post-processing oiling process in the industry. Oiling the fibers can make the fibers have a smooth and soft feel, improve the antistatic properties of the fibers, reduce the friction between fibers and between fibers and other objects, and make the processing process go smoothly. In addition, fiber oiling can also improv...

Problems solved by technology

But it is not limited to the aforementioned three patent solutions that have the following disadvantages: one, because the positions of the two fuel injection pipes correspondingly arranged up and down cannot be changed, thus causing the fiber tow channel between the upper and lower fuel injection pipes The height cannot be adjusted, so on the one hand, it is inconvenient for threading (threading refers to passing the fiber tow through the aforementioned fiber tow channel), because the greater the height of the fiber tow channel, the easier it is to thread, and vice versa. It is not conducive to adaptive adjustment of the height of the fiber tow channel according to the change of the fiber tow or fiber material; second, because the linear velocity of the fiber tow is relatively high, if the nozzles are sprayed according to the teachings of CN201400791Y and CN205062253U Oil, so although the fiber filament speed can be obtained from the surface and the outside, the waste of the oil is amazing, and if the oil injection holes provided on the oil injection pipe are used to spray oil according to CN206941030U, although the former can be used in a certain Avoid oil waste to a certain extent, but due to the lack of oil pressure protection measures, it is not enough to achieve uniform oiling effect from the surface to the inside of the fiber tow
