Web curtain receiver

Abstract

The invention discloses a web curtain receiver which comprises a web curtain rack, a base, a plurality of transmission rollers, a first driving mechanism, a first lifting mechanism, a second lifting mechanism and a controller, the transmission rollers are rotationally installed on the web curtain rack, web curtains are arranged on the transmission rollers, and the first driving mechanism is in transmission connection with the transmission rollers; a first melting nozzle and a second melting nozzle are arranged above the web curtain at intervals, and air suction mechanisms are arranged at the positions, corresponding to the first melting nozzle and the second melting nozzle, below the web curtain; and the first lifting mechanism is installed at the end, close to the first melting nozzle, of the base, the second lifting mechanism is installed at the end, close to the second melting nozzle, of the bottom of the base, the power output ends of the first lifting mechanism and the second lifting mechanism fix the web curtain rack, and the distances between the first melting nozzle and the net curtain and between the second melting nozzle and the net curtain in the vertical direction are adjustable. The web curtain receiver can quickly and conveniently adjust the height between the web curtain and the melting nozzles, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of nonwoven fabric production equipment, in particular to a net curtain receiver. Background technique [0002] In the production of nonwoven fabrics, it is mainly divided into three basic processes: fiber preparation, web forming and laying, and fiber bonding or consolidation. Among them, the mechanical equipment corresponding to fiber preparation is mainly opening machine, carding machine and cotton feeding machine, the mechanical equipment corresponding to web forming and laying is web laying machine, and the mechanical equipment corresponding to fiber bonding or consolidation is Acupuncture machine. The fiber web is the most important semi-finished product in the production of nonwovens, and the quality of the web is an important factor that directly affects the performance and use of nonwovens. With the improvement of non-woven technology and equipment, the web-laying machine has become the main web-forming met...

Problems solved by technology

According to different requirements, the web thickness of the cotton web on the net forming curtain is also different, and in the process of laying the cotton net, if the distance between the net curtain and the upper nozzle is too far, the cotton net will fall for a long distance, which will easily cause fluff And the laying is slow. If the distance between the net curtain and the nozzle above is too close, the distance between the net curtain and the nozzle cannot meet the requirements of web formation for a cotton web that requires a large thickness. Therefore, it is necessary to adjust the net curtain and the nozzle in time. The relative height of the spray head, the height adjustment method of the existing net curtain is mostly achieved by removing the net curtain and the front and rear driving rollers of the net curtain, and installing them at the required height separately, which is cumbersome to assemble and disassemble, time-consuming and laborious
