Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings. The longitudinal direction in this specification refers to the direction extending along the length of the nonwoven fabric, and the transverse direction described in this specification refers to the direction along the width of the nonwoven fabric.

[0029] A dry-process nonwoven pretreatment unit, used for combing, laying and trimming the cotton fibers unpacked by a bale opener. The pretreatment unit mainly includes: used to uniformly transport the fibers in the cotton channel The air-supply cotton uniform mechanism 10 sent into the cotton box, the cotton box arranged at the downstream of the wind-sent cotton uniform mechanism 10, the web laying mechanism 50 and the trimming mechanism 60 arranged at the downstream of the cotton box.

[0030] Wherein the cotton box includes an upper cotton box 20 and a lower cotton box 40, the upper cotton box 20 is connected to the ai...

Abstract

The invention relates to a non-weaving pretreatment unit by a dry method, comprising a pneumatic cotton evener mechanism, a cotton box and a lapping mechanism. The pneumatic cotton evener mechanism comprises an air passage, a pair of swing baffle plates and a reciprocating swing mechanism. A cotton fibre inlet is arranged at one side where the air passage is connected with a cotton feeding curtain; a cotton fibre outlet is arranged at one side where the air passage is connected with the cotton box, wherein the cotton fibre outlet is wider than the cotton fibre inlet; the pair of swing baffle plates are pivotally and rotatably arranged inside the air passage, and the rotating shafts of the swing baffle plates are located at both sides of the cotton fibre inlet; the reciprocating swing mechanism is in synchronous transmission connection with the pair of swing baffle plates, and is respectively used for evenly feeding the fibre entering from the cotton fibre inlet to the air passage to the cotton box. In the invention, the pneumatic cotton evener mechanism is additionally provided with a pair of swing baffle plates which can swing in a reciprocating way so that the cotton fibre entering the air passage by air pressure is evenly dispersed in the width amplitude direction of the cotton box, the cotton of the fibre layer is evenly distributed, and the problem of unevenness of the fibre is solved.

Description

technical field [0001] The invention belongs to the field of non-woven equipment, in particular to a non-woven pretreatment unit and its cotton feeding device. Background technique [0002] In the prior art, the manufacturing process of nonwoven fabrics is mainly divided into pretreatment process and stitching process. The pretreatment process mainly includes: unpacking→rough opening→fine opening→cotton feeding→carding→laying. The short fiber is processed by bale opener, rough opener, fine opener, cotton feeding box, carding machine and net laying machine respectively. On the one hand, the use of multiple processing equipment is expensive and takes up space. On the other hand, it is difficult to accurately control the amount of cotton feeding and the speed of the assembly line among multiple equipment. Therefore, the weight of non-woven products manufactured by using existing non-woven equipment The error rate is high. [0003] See Chinese patent 200410016392.7, the cotton...
