Novel semi-continuous high-speed spinning machine

Abstract

The invention relates to a novel semi-continuous high-speed spinning machine which comprises a rack, a glue supply device, a filament strip forming device, a spinning device and a winding device. The spinning device comprises a spinning roller which is transversely arranged relative to the operating surface of a spinning face, and the two ends of the spinning roller are fixed on the rack. The novel semi-continuous high-speed spinning machine improves spinning speed, ensures that filament strips are sufficiently reacted, and then achieves the purposes of ensuring the quality of the filament strips, improving production efficiency and reducing spinning cost.

Description

technical field

[0001] The present invention relates to a kind of spinning equipment, in particular, the present invention relates to a kind of semi-continuous high-speed spinning machine. Background technique

[0002] Pure methyl cellulose is extracted from cellulose raw material, called pulp. Treat with caustic soda and carbon disulfide to obtain orange-yellow cellulose xanthate sodium, and then dissolve it in dilute sodium hydroxide solution to become viscous spinning stock solution, called viscose. After the viscose is filtered, matured and defoamed, it is wet-spun, and the coagulation bath is composed of sulfuric acid, sodium sulfate and zinc sulfate. Sodium cellulose xanthate in the viscose reacts with sulfuric acid in the coagulation bath to decompose, and the cellulose is regenerated and precipitated. The obtained cellulose fiber becomes viscose fiber after washing, desulfurization, bleaching and drying. Viscose filament is a kind of viscose fiber, which is also ma...

Examples

Embodiment 1

[0089] Such as Figure 7 , Figure 8 with Figure 10 As shown, the semi-continuous high-speed spinning machine provided in this embodiment includes a frame 1, a glue supply device 2, a filament forming device 3, a spinning device 4, and a winding device 5, and the spinning device 4 includes a spinning device There are three spinning rolls 40, the spinning rolls 40 are arranged transversely to the operating surface of the spinning surface, and the spinning rolls 40 are parallel to each other.

[0090] Such as Figure 9 As shown, the operating surface of the spinning surface is a horizontal working surface located in the spinning surface area, and the horizontal arrangement of the spinning roller 40 relative to the operating surface of the spinning surface means that when the spinning worker faces the winding device, the spinning roller 40 is installed horizontally relative to spinning workers.

[0091] There are three spinning rolls 40 , which are drafting roll 404 , coagul...

Embodiment 2

[0098] Such as Figure 11 As shown, this embodiment is basically the same as Embodiment 1, except that the spinning roll 40 is arranged obliquely from one end to the other relative to the horizontal plane. The spinning roll 40 has a length of 1400 mm and a diameter of 100 mm.

Embodiment 3

[0100] This embodiment is basically the same as Embodiment 1, and the difference is: among the three spinning rollers 40, one of the spinning rollers 40 is connected to a driving device alone, and the other two spinning rollers 40 are connected to a driving device; the length of the spinning rollers 40 is 800mm , with a diameter of 50mm. Of course, it is also possible that the three spinning rollers 40 are all connected to one driving device.
