Description

Net pressing and floating preventing device of lapping machine

Technical Field

The utility model relates to the technical field of non-woven equipment, in particular to a net pressing and floating preventing device of a lapping machine.

Background

The lapping machine is an important device in the production of short-filament non-woven fabric, and is used for repeatedly lapping single fiber webs output by a carding machine into multiple layers of thick fiber webs with required width.

The lapping machine is mainly divided into a full-clamping high-speed lapping machine and a four-curtain common lapping machine. The high-speed lapping machine is mainly used on a high-speed production line such as a spunlace production process, and belongs to high-end equipment; the most widely used are also the conventional types of lappers. The main difference of the common lapping machine and the high-speed lapping machine in performance is that the common lapping machine has obvious lapping phenomenon except lapping speed, lapping uniformity and control mode, the fiber web is easily disturbed by air flow and is unevenly drawn in the process of drifting, so that the flatness of the paved multi-layer fiber web is poor, the height is bulky, a special cotton pressing device is required to be arranged, and the overall height of the whole machine is greatly increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a net pressing and floating preventing device of a lapping machine, which can effectively solve the problems in the background technology.

The technical scheme for realizing the aim is as follows: lapping machine presses net and prevents device that wafts, including the frame, installs end curtain in the frame, and the top of end curtain is provided with the lapping dolly that reciprocates about the track and laid the fibre web on end curtain, its characterized in that: two sides of the lapping trolley are rotatably provided with symmetrically arranged net pressing rollers, the left end and the right end of the rack are provided with two upper guide rollers and two fixed supporting blocks which are symmetrically arranged on the left side and the right side of the bottom curtain, the fixed supporting blocks are positioned below the inner sides of the upper guide rollers on the corresponding sides, the lapping trolley is positioned between the fixed supporting blocks on the two sides, the two upper guide rollers and the two fixed supporting blocks are both positioned above the bottom curtain, and the two lower guide rollers which are symmetrically arranged on the left side and the right side are arranged below the bottom curtain; the two upper guide rollers and the two lower guide rollers are rotatably connected with the frame, the net pressing curtain is wound between the two lower guide rollers, two ends of the net pressing curtain are respectively connected to the corresponding fixed supporting blocks after bypassing the upper guide rollers and the net pressing rollers on the corresponding sides, and the net pressing curtain between the net pressing roller and the corresponding fixed supporting blocks is parallel to the fiber net laid on the bottom curtain.

Further, the net pressing curtain is made of polytetrafluoroethylene high-temperature cloth.

Further, the lapping trolley comprises a support, a pair of upper net guide rollers are mounted on the upper portion of the support, a pair of lower net guide rollers are mounted on the lower portion of the support, a fiber net inlet is formed between the upper net guide rollers, and a fiber net outlet is formed between the lower net guide rollers.

Further, the rolling surface of the screen pressing roller is slightly lower than the lower end surface of the lower screen guiding roller.

The utility model has the beneficial effects that:

when the utility model works, the lapping trolley drives the two side lapping rollers to do reciprocating motion, when the lapping trolley moves leftwards, the right side lapping roller drives the lapping curtain wound on the right side lapping roller to gradually extend leftwards and lap the paved fiber net, while the lapping curtain wound between the left side lapping roller and the left side fixed support is gradually shortened along with the lapping trolley in the process of moving leftwards, when the lapping trolley moves rightwards, the left side lapping roller drives the lapping curtain wound on the left side lapping roller to gradually extend rightwards and lap the paved fiber net, while the lapping curtain wound between the right side lapping roller and the right side fixed support is gradually shortened along with the lapping trolley in the process of moving rightwards, and the process is circulated in a reciprocating way to lap the fiber net layer by layer on the bottom curtain, so that the flattened and compacted multilayer fiber net is prepared, and no relative motion exists between the lapping curtain and the fiber net layer on the bottom curtain.

Detailed Description

As shown in fig. 1 and 2, the utility model comprises a frame 1, a bottom curtain 2 is arranged on the frame 1, a lapping trolley 3 which reciprocates left and right along a track and lays a fiber net on the bottom curtain 2 is arranged above the bottom curtain 2, the lapping trolley 3 comprises a support 3.1, a pair of upper guide rollers 3.2 is arranged at the upper part of the support 3.1, a pair of lower guide rollers 3.3 is arranged at the lower part of the support 3.1, a fiber net inlet is formed between the upper guide rollers 3.2, and a fiber net outlet is formed between the lower guide rollers 3.3.

A pair of lower net guide rollers 3.3 of the net laying trolley 3 are rotatably provided with symmetrically arranged net pressing rollers 4 at both sides, the rolling surface of each net pressing roller 4 is slightly lower than the lower end surface of the lower net guide roller 3.3, two upper guide rollers 5 and two fixed supporting blocks 6 are symmetrically arranged at both sides of the bottom curtain 2 at both sides of the frame 1, the fixed supporting blocks 6 are positioned below the inner sides of the upper guide rollers 5 at the corresponding sides and fixedly connected with the frame 1, the net laying trolley 3 runs between the fixed supporting blocks 6 at both sides, the two upper guide rollers 5 and the two fixed supporting blocks 6 are positioned above the bottom curtain 2, two lower guide rollers 7 are symmetrically arranged below the bottom curtain 2, the two upper guide rollers 5 and the two lower guide rollers 7 are rotatably connected with the frame 1, a net pressing curtain 8 is wound between the two lower guide rollers 7, the net pressing curtain 8 is made of polytetrafluoroethylene high-temperature cloth, and both ends of the net pressing curtain 8 respectively pass through the upper guide rollers 5 and the upper guide rollers 5 at the corresponding sides, The net pressing roller 4 is connected with the corresponding fixed supporting block 6, and the net pressing curtain 8 between the net pressing roller 5 and the corresponding fixed supporting block 6 is parallel to the fiber net laid on the bottom curtain 2.
