Multi-roller cotton blending machine

Abstract

The invention relates to a multi-roller cotton blending machine. The cotton blending machine comprises one or more groups of series connection machine sets. Each machine set has a condenser, an automatic cotton feeding mechanism, a multi-roller cotton layer conveying channel, an output pipe, a cotton blower system and an electrical automation control system. The multi-roller cotton layer conveyingchannel is driven by a variable-frequency and variable-speed motor and comprises several working rollers, several hair stripping rollers and a cleaning roller located at the top end of a wall plate rack, wherein the working rollers and the hair stripping rollers are arranged at intervals and are located on the wall plate rack. One working roller and one hair stripping roller form one cotton layerconveying channel. Coaxial straight needle rollers are arranged in the working rollers and the hair stripping rollers. In the invention, a high-efficiency and high-yield multi-roller cotton blendingwarehouse has advantages that the fibers are not damaged 100%; a blending uniformity is high; processing efficiency is increased by at least 3 times; cotton fiber molding is good; the machine is designed reasonably and beautifully; a dustproof effect is good; the machine is intelligently controlled; installation is convenient; and a land occupation space is saved and so on.

Description

technical field [0001] The invention relates to the technical field of textile and nonwoven fabric machinery, in particular to a multi-roller cotton blending machine. Background technique [0002] There is a double-roller slanting nail curtain cotton mixing warehouse, which includes a frame wall panel, a transmission mechanism, a cotton condenser, an automatic cotton feeding mechanism, a double-roller mechanism, and a single-layer slant nail curtain. Conveying transmission mechanism, output curtain opening mechanism, cotton conveying fan system and electrical automation control system. The cotton condenser includes a fixed perforated circular screen that accepts the coarsely opened materials delivered by the front-end equipment, and a cotton air separation and dust removal device, so that the air and dust in the cotton wool opened in the front road can be separated as much as possible, and the remaining cotton wool falls into the mixed cotton bin; the automatic cotton feedi...

Problems solved by technology

The cotton condenser includes a fixed perforated circular screen that accepts the coarsely opened materials delivered by the front-end equipment, and a cotton air separation and dust removal device, so that the air and dust in the cotton wool opened in the front road can be separated as much as possible, and the remaining cotton wool falls into the mixed cotton bin; the automatic cotton feeding mechanism includes a cotton feeding flat curtain, a curtain roller located on the wall panel frame, front and rear photoelectric devices and transmission devices, and the front photoelectric device automatically controls the height and amount of cotton delivered by the front equipment , the rear photoelectricity automatically controls the height of the cotton position close to the transmission mechanism of the single-layer oblique nail curtain; the double-roller mechanism includes two sawtooth rollers, a stripping roller (1 piece) and a working roller arranged at intervals on the wall panel frame Combination of rollers (1 piece) and the oblique nail curtain in the middle; the single-layer oblique nail curtain transmission mechanism includes a oblique nail curtain with different widths, two curtain guide rollers and curtain support rollers to form a cotton layer conveying channel , with the improvement of production capacity of single-layer cotton web through frequency conversion and speed regulation of inclined nail curtains, the mixing uniformity of different varieties of cotton batts has a downward trend from 50%; and because of the technical limitations of the equipment itself, the significant decline in uniformity seriously affects the user's actual production demand

And the oblique nail curtain (composed of rubber curtains, wooden sticks, metal nails, etc.) rubber curtains are easy to discolor and peel, wooden sticks are easy to break, and metal nails are easy to fall off>, the fed cotton is mixed, and it cannot be cleaned and evenly fed into the lower The first process, the single-layer inclined nail curtain transmission mechanism set in the middle of the double-roller beater, prevents the cotton wool from the front and rear working rollers and stripping rollers from being completely stripped and transferred; the working rollers and stripping rollers cannot fully 100% mixing and opening effect without damaging the fibers (the phenomenon of slanting nail curtain wrapping and belting back). When the mixing ratio reaches up to 50%, the production capacity is limited; at the same time, the double-roller diagonal nail curtain mixing warehouse is only suitable for Various chemical fiber raw materials are blended, and are only suitable for raw material lengths of 38mm to 76mm, and raw material lengths greater than 76 to 120mm are basically unable to be mixed and output, and serious winding occurs, and the normal mechanical speed of 40m / min cannot be guaranteed, and the total installed power 15KW, the production capacity is 330Kg / h, which seriously restricts the carding process of the subsequent process. There are many flying flowers on the shaft head, the machine has many faults, frequent shutdowns, and cleaning every 12 hours. The labor intensity of the workers is high, the environment is harsh, Disadvantages such as low efficiency and low production capacity
