Non-woven fabric lapping device with rough selvedge suction system and application in non-woven fabric production

Abstract

The invention discloses a non-woven fabric lapping device with a rough selvedge suction system and application in non-woven fabric production. The non-woven fabric lapping device comprises a first inclined curtain and a rack, wherein a first flat curtain and a lapping sliding frame are arranged on the rack, a ring curtain is arranged on the lapping sliding frame and a driving roller, the driving roller is connected with a right-angle speed reducer through a chain, the right-angle speed reducer is in shaft connection with a ring curtain motor, a lapping trolley is arranged below the lapping sliding frame, the lapping trolley is connected with a reciprocating transmission roller through a chain, the reciprocating transmission roller is connected with a second motor through a chain, two output rollers are arranged at the bottom of the lapping trolley, a bottom flat curtain is arranged below the rack, a pressing roller is arranged on the right side of the rack, a conveying curtain is arranged on the right side of the pressing roller, a rough selvedge suction pipe is arranged on the right side of the conveying curtain, cross lapping is changed into progressive reciprocating lapping, produced non-woven fabric products are uniform in thickness and neat in edge, super-thick selvedges do not need to be cut off in the later period, and wide application and popularization value is achieved in the technical field of non-woven fabric manufacturing.

Description

technical field [0001] The invention belongs to the field of non-woven fabric production, and in particular relates to a non-woven fabric web laying device and the technical field of application thereof. Background technique [0002] In the production of nonwovens, it is mainly divided into three basic processes: fiber preparation, web forming and laying, and fiber web bonding or consolidation. 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, cross-lapping has become the main web-forming method in the non-woven industry. [0003] The net-laying machine is connected to the rear of the carding equipment, and its function is to spread the formed cotton web evenly. The technical feature of the cross-lapping net is that the net-laying rack and the output conveyor are plac...

Problems solved by technology

[0007] In order to solve the above-mentioned lateral shrinkage of the fiber web in the laying of the traditional cross-lapper, the overfeeding of the fiber web during the reverse deceleration / acceleration process of the investigation of the web laying survey makes the thickness of the fiber web uneven and the two sides are heavier than the middle, and the subsequent reinforcement In order to solve the problem of lateral shrinkage of the product due to drafting in the process, the purpose of the present invention is to provide a non-woven fabric laying device with a burr-absorbing system, which changes the connection structure between the traditional cross-lapper and the spreading machine, and changes the cross-laying to a passing Into the reciprocating laying, the thickness of the non-woven fabric produced is uniform, and it can form a non-woven fabric with a part of the fiber arrangement in the radial direction and the weft direction, which improves the warp and weft breaking strength of the non-woven fabric, greatly improving The mechanical properties of the produced non-woven fabrics have a wide range of popularization and application value in the field of non-woven fabric manufacturing technology
