Embodiment 1

[0022] A non-woven high-efficiency carding system of the present embodiment includes a cylinder 1, a lower doffer 2, an upper doffer 3 installed on the frame main body, a plurality of carding units composed of a work roll 4 and a stripping roll 5, And the transfer roller 6, between the lower doffer 2 and the upper doffer 3, there is a buffer carding unit for the surface high-speed airflow generated by the high-speed rotation of the branch cylinder 1, and the buffer carding unit includes a group of buffer work rolls 8 and buffer stripping rollers 9. The buffer stripping roller 9 is located between the buffer work roller 8 and the upper doffer 3 . An upwind roll 10 is provided between the upper doffer 3 and the closest work roll 4 , and a leeward roll 7 is provided between the lower doffer 2 and the buffer work roll 8 . The distance between the buffer work roll 8 and the cylinder 1, between the buffer stripping roller 9 and the cylinder 1, and between the buffer work roll 8 and ...

Embodiment 2

[0026] A nonwoven high-efficiency carding system of this embodiment is different from Embodiment 1 in that the distance between the buffer work roll 8 and the cylinder 1 is 0.10 m, and the distance between the buffer stripping roller 9 and the cylinder 1 is 0.10 m. The gauge is 0.20mm, and the gauge between the buffer work roll 8 and the buffer stripping roller 9 is 0.20mm.

Embodiment 3

[0028] A nonwoven high-efficiency carding system of this embodiment is different from Embodiment 1 in that the distance between the buffer work roll 8 and the cylinder 1 is 0.25mm, and the distance between the buffer stripping roller 9 and the cylinder 1 is 0.25 mm. The gauge is 0.35mm, and the gauge between the buffer work roll 8 and the buffer stripping roller 9 is 0.40mm.

Abstract

The invention discloses a non-woven efficient carded web formation system. The system comprises a cylinder, a lower doffer, an upper doffer, a plurality of carding units and a transferring roller which are installed on a rack body, wherein the carding units are formed by work rollers and stripping rollers; a buffer carding unit used for shunting surface jet stream generated by high-speed rotation of the cylinder is arranged between the lower doffer and the upper doffer and comprises a group of buffer work rollers and a group of buffer stripping rollers; and the buffer stripping rollers are arranged between the buffer work rollers and the upper doffer. The non-woven efficient carded web formation system can overcome the defects of low yield, poor fiber web appearance and uniformity and the like in the prior art, effectively improve the carding performance of a carding machine and the uniformity of a doffer output fiber web, increase the fiber transfer quantity between the cylinder and the doffers, and achieve efficient carded web formation of the complete carding machine.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to an efficient carding web forming system installed on a non-woven carding machine. Background technique [0002] Fiber carding is a key process in the web-forming process of dry-laid nonwovens. The carding machine combs the opened and mixed fibers into a thin web composed of single fibers, which is then laid into a web or directly consolidated. The function of the carding machine has four aspects: (1) Thoroughly comb the mixed fiber raw material to make it into a single fiber state; (2) Make the various fiber components in the fiber raw material be further mixed evenly; (3) Further remove the impurities in the raw material Impurities; (4) make the fibers parallel and straight. The uniformity and quality of the fiber web output from the carding machine has a direct impact on the uniformity and quality of the final nonwoven material. [0003] In the prior art, the invention paten...
