Cross lapper with cotton pressing function

Abstract

The invention relates to a cross lapper with a cotton pressing function. The cross lapper comprises a lapping carriage assembly, wherein the lapping carriage assembly comprises a front wallboard, a rear wallboard, a left lapping roller and a right lapping roller of a lapping carriage, and is characterized by also comprising a cotton pressing mechanism; the cotton pressing mechanism comprises a left cotton pressing roller and a right cotton pressing roller, a left upper guide roller and a left lower guide roller of a cotton pressing curtain, a right upper guide roller and a right lower guide roller of the cotton pressing curtain, and the cotton pressing curtain; the left cotton pressing roller is supported between the front wallboard and the rear wallboard of the lapping carriage; the right cotton pressing roller is supported between the front wallboard and the rear wallboard of the lapping carriage; the left upper guide roller of the cotton pressing curtain is supported on the left end of a rack; the left lower guide roller of the cotton pressing curtain is supported on the left end of the rack; the right upper guide roller of the cotton pressing curtain is supported on the right end of the rack; the right lower guide roller of the cotton pressing curtain is supported on the right end of the rack; the left end of the cotton pressing curtain is fixedly connected with the left end of the rack; the left cotton pressing roller, the left upper guide roller and the left lower guide roller of the cotton pressing curtain, the right upper guide roller and the right lower guide roller of the cotton pressing curtain, and a right cotton pressing roller are sequentially sleeved on the middle part of the cotton pressing curtain; the right end of the cotton pressing curtain is fixedly connected with the right end of the rack. The lapping quality and the lapping efficiency are ensured, and the quality of a non-woven product is ensured.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a web-laying machine with the function of pressing cotton. Background technique [0002] As known in the industry, the production equipment of complete sets of non-woven products such as non-woven fabrics and non-woven felts mainly includes opening machines, carding machines, web laminating machines and needle punching machines (or spunlace machines). The fiber is opened and supplied to the carding machine. The non-woven fiber carded by the carding machine is supplied to the web-laying machine for laying. [0003] The web-laying machine is an important part of the complete set of non-woven product production equipment, and the technical information about the web-laying machine can be found in the published Chinese patent documents, such as CN2637519Y (web-laying machine), CN100554539C (Laying mechanism with compensation function), CN201272889Y (Cross-lapp...

Problems solved by technology

[0006] Undoubtedly, the quality of the web laying effect will have a direct impact on the quality of non-woven products. For example, due to factors such as electrostatic effect, air flow, and the speed of the web laying car during the web laying process, fiber sticking to the roll often occurs. , roll winding and non-woven fiber cotton net floating (floating), and the faster the reciprocating speed of the laying trolley, the more prominent the fiber sticking roll, winding roll and floating (floating) phenomenon, while the fiber sticking roll, Winding and floating not only cause disordered webs but also affect the uneven thickness of the non-woven fiber cotton layer on the web-forming curtain, which eventually leads to inconsistent weights of non-woven products after needle punching and affects the speed of web laying, especially when the fibers are bonded to rolls In severe cases, it is necessary to clean the left and right web rolls in the shutdown state, which not only increases the extra work intensity of the online workers, but also delays the efficiency of the web lapper

In particular, once the web-laying machine stops, the front feeding curtain stops feeding, and the rear needle loom stops needle punching. This unfavorable factor of continuous reaction has a serious impact on the production efficiency of non-woven products.

Therefore, how to avoid fiber sticking to rollers and cotton web floating etc. has been perplexing the industry for a long time, but there is no beneficial enlightenment to solve this technical problem in the Chinese and foreign patents and non-patent literatures disclosed so far.
