Description
Technical Field
The utility model relates to a polyester staple fiber processing technology field especially relates to a false twist equipment for polyester staple fiber.
Background
The terylene, namely polyester fiber, has the advantages of good crease resistance and shape retention, higher strength and elastic recovery capability, firmness and durability, crease resistance, no ironing and no hair sticking. The polyester staple fiber is obtained by spinning polyester fiber into a tow and cutting the tow. The false twisting means that both ends of the multifilament are held and twisted by a twisting device in the middle of both ends of the multifilament, the multifilament obtains twists of the same number with opposite twist directions at both ends of the twisting device, and the sum of the twists of the whole yarn is 0. The false twisting device needs to twist fibers by using a friction wheel, the friction wheel made of ceramic materials and polyurethane materials is commonly used in the market, the friction wheel made of ceramic materials is good in wear resistance, high in strength and long in service life, but easily damages the fibers, reduces the tension of the fibers, and the friction wheel made of polyurethane materials is small in damage to the fibers, but poor in wear resistance, short in service life and high in use cost.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a false twisting device for polyester staple fibers comprises a base 1, wherein a driving shaft 2 and two driven shafts 3 are connected to the base 1 through bearings, the driving shaft 2 and the two driven shafts 3 are arranged in a regular triangle shape, a plurality of friction discs 4 are respectively arranged on the driving shaft 2 and the driven shafts 3 from top to bottom, the topmost friction disc 4 is a leading-in disc 5, the bottommost friction disc 4 is a leading-out disc 6, the friction discs 4 are composed of a fixed disc 7 and a friction sleeve 8, the fixed disc 7 is fixed on the driving shaft 2 and the driven shafts 3, and the friction sleeve 8 is sleeved outside the friction sleeve 8.
Wherein, the friction discs 4 on the driving shaft 2, one of the driven shafts 3 and the other driven shaft 3 are alternately arranged from top to bottom, and the diameters of the friction discs 4 are gradually increased from top to bottom.
Wherein, the outside bottom circumference interval of fixed disk 7 is provided with inserted block 9, and the slot 10 that matches with inserted block 9 is seted up to the inboard bottom of friction cover 8, and the material of fixed disk 7 is pottery, and the material of friction cover 8 is polyurethane.
During false twisting of polyester staple fibers, the driving mechanism drives the driving shaft 2 and the driven shaft 3 to rotate, so that the friction discs 4 are driven to rotate, the polyester staple fibers enter the friction discs 4 through the guide-in disc 5, shuttle among the friction discs 4 and then are guided out through the guide-out disc 6, and false twisting is completed among the friction discs.
