Clamping type feeding device of pre-pricking machine

Abstract

A clamping-type feeding device of pre-lunge machine comprises a frame, and some elements as fiber network transmitter and power device mounted on the frame, while the power device is connected with the fiber network transmitter. The fiber network transmitter comprises upper and lower transmitting curtains, upper and lower active rollers mounted on the frame, upper and lower compressing rollers, upper and lower small feeding rollers, while two ends of compressing rollers are rotationally mounted on the frame. The upper and lower small feeding rollers via roller sheathes are individually arranged on the rotary axles of compressing rollers, while they extruded outside the frame. The upper transmitting curtain is tensioned on the upper active roller, upper compressing roller and upper small feeding roller, while the lower transmitting curtain is tensioned on the lower active roller, lower compressing roller and lower small feeding roller. The upper and lower transmitting curtains form backward Y-shaped space between them. The invention can be engaged with the material inlet of pre-lunge machine, to transmit fiber network via low tension rate, while the surface and uniformity of fiber network will not be damaged.

Description

technical field [0001] The invention relates to a fiber web pre-feeding device in a complete set of non-woven machinery equipment, and more specifically relates to a clamping type feeding device of a pre-looming machine. Background technique [0002] As shown in Figure 1, the clamping feeding device of the existing pre-puncher generally includes a frame 1, a fiber web conveying mechanism and a power mechanism, and the above fiber mesh conveying mechanism and the power mechanism are all installed on the frame 1, and the It is connected with the transmission mechanism of the web conveying mechanism. The fiber web conveying mechanism generally includes an upper transmission curtain 2, a lower transmission curtain 3, an upper feeding roller 4, a lower feeding roller 5, an upper driving roller 6, a lower driving roller 7, an upper tension roller 8 and a lower tension roller 9, Both ends of the upper and lower feed rollers 4, 5, the upper and lower driving rollers 6, 7 and the up...

AI Technical Summary

Problems solved by technology

[0005] Due to the relatively large diameters of the upper and lower feed rollers 4 and 5, the distance between the nip point of the upper and lower feed rollers 4 and 5 and the first row of needles of the pre-looming machine is generally about 120 cm, so the fiber web leaves the upper and lower The lower feeding rollers 4 and 5 will expand after the nip point. Therefore, when feeding the fiber web to the pre-looming machine, the fiber web has a long conveying distance and large conveying resistance, resulting in a large traction rate and uneven feeding. At the same time, because the upper and lower feeding rollers 4 and 5 are generally embedded with ring-shaped mesh guide sheets 12, it is easy to scratch and damage the fibers of the fiber web, reducing the quality of the finished product
