Abstract
The collecting and distributing homogenizer for air-lay machine includes one pricker roll and one air conduit communicated with pricker roll and below the pricker roll. The air conduit has one bent head with contracted cross section and one belled part connected to the bent head. The collecting and distributing homogenizer blows off fiber from the surface of the pricker roll with high speed airflow, and the fiber is first collected in the bend and then distributed for being spread onto the curtain to form homogeneous fiber net. The present invention is especially suitable for making thin fiber net.
Description
Technical field:
The present invention relates to a kind of air channel of random web-laying equipment.
Background technology:
Existing random web-laying equipment air channel (all wire stitchers) is straight cartridge form, and when air-flow arrived the fiber pressure-vaccum on the licker-in than lace curtaining, skewness can not form uniform fibre web.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructurely, the air draught air-flow can evenly disperse fiber, forms the collecting and distributing homogenizer of the random web-laying equipment of even fibre web.
Technical solution of the present invention is:
A kind of collecting and distributing homogenizer of random web-laying equipment comprises the air channel that communicates with licker-in, it is characterized in that: the air channel is positioned at the position of licker-in below, is arranged to the elbow shape, the bend part cross-sectional constriction, and it is gradually thick horn-like that the air channel of elbow bottom is.
The present invention is rational in infrastructure, by high velocity air fiber is blown off from the licker-in dial, earlier fiber is focused on the elbow (this is in middle section, whole wind road minimum) in air channel, then, the duct cross-section diffusion utilizes the air draught air-flow that fiber is evenly disperseed, lay is to defeated lace curtaining, form uniform fibre web, can effectively eliminate the fibre web crosswise unevenness, be particularly suitable for slim fiber web.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of one embodiment of the invention.
Fig. 2 is the right view of Fig. 1.
The specific embodiment:
A kind of collecting and distributing homogenizer of random web-laying equipment, comprise the air channel 2 that communicates with licker-in 1, the air channel is positioned at the position of licker-in 1 below, is arranged to the elbow shape, it is gradually thick horn-like that bend part 3 cross-sectional constriction (promptly in middle section, whole air channel minimum), the air channel of elbow bottom are.
