Lapping carriage with cotton pressing function

Abstract

The invention provides a lapping carriage with a cotton pressing function and belongs to the technical field of nonwoven machines. The lapping carriage comprises a lapping carriage assembly, the lapping carriage assembly comprises a front wall plate of the lapping carriage, a rear wall plate of the lapping carriage, a left lapping roller, a right lapping roller and a lower cotton delivery ring lattice guide roller, wherein the front wall plate of the lapping carriage corresponds to the rear wall plate of the lapping carriage, and the front wall plate, the rear wall plate and a machine frame rear cross beam form a rolling pair; the left and right lapping rollers bilaterally correspond to each other and are supported between the front wall plate of the lapping carriage and the rear wall plate of the lapping carriage; the position on the upper portion, corresponding to the right lapping roller, of the lower cotton delivery ring lattice guide roller is supported between the front wall plate of the lapping carriage and the rear wall plate of the lapping carriage; the lapping carriage is characterized by comprising a cotton pressing mechanism, the cotton pressing mechanism is used for pressing nonwoven fiber cotton fleece laid out due to the synergistic effect of the right and left lapping rollers, and the cotton pressing mechanism is arranged on the machine frame and connected with the front wall plate and the rear wall plate of the lapping carriage. The phenomena that the nonwoven fiber cotton fleece from the left and right lapping rollers is ethereal so as to be disorderly webbed and even stuck to the rollers are avoided, and the lapping quality and efficiency are ensured.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a net laying trolley with a cotton pressing function. Background technique [0002] As is known in the industry, the production equipment for complete sets of non-woven products such as non-woven fabrics and non-woven felts mainly includes openers, carding machines, web laying machines and needle punching machines (or spunlace machines). The fibers are opened and supplied to the carding machine, and the non-woven fibers combed by the carding machine are supplied to the web laying machine for web laying, and after the web laying machine lays the web, it is sent to the acupuncture machine for acupuncture or spunlace spunlace to form a non-woven product. [0003] Latter is an important part of the complete set of non-woven product production equipment, and the technical information about the lapper can be found in the published Chinese patent documents, such ...

Problems solved by technology

[0006] Furthermore, as the industry knows, the quality of the net laying effect will have a direct impact on the quality of non-woven products. For example, due to factors such as electrostatic effects, airflow, and the speed of the net laying trolley during the net laying process of the net laying trolley, fibers often appear. The phenomenon of sticking roll, winding roll and floating (floating) of non-woven fiber cotton web, and the faster the reciprocating speed of the laying trolley, the more prominent the phenomenon of fiber sticking roll, winding roll and floating (floating), while the fiber sticking Rollers, winding rollers and floating not only cause disordered webs, but also affect the uneven thickness of the non-woven fiber cotton layer on the web curtain, and eventually lead to inconsistent weights of non-woven products after needle punching, and affect the speed of web laying, especially when the fibers are sticky. When the roller is seriously wound, it is necessary to stop the machine to clean the left and right web rollers, 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.
