Net laying mechanism with compensation function

Abstract

The invention relates to a lapping mechanism having a compensation function, and lapping the mechanism belongs to the technical field of a cotton web lay-up device in complete set non-woven mechanical equipment. The lapping mechanism comprises a lapping cart, a lapping trolley, a pair of first drive roll and second drive roll, a first conveying curtain, a second conveying curtain, and a pair of hauling wire ropes with the both ends fixed on a machine frame and the lapping trolley and the middle part mutually implicated with the lapping cart, and also comprises a first fiber web compensation device. The position of the first fiber web compensation device on the machine frame is arranged at the identical end provided with the first drive roll and the second drive roll machine frame, the first fiber web compensation device is connected with the first conveying curtain, the second conveying curtain, and a pair of hauling wire ropes, a second fiber web compensation device, the motion direction of which is opposite to the motion direction of the first fiber web compensation device is arranged on the lapping cart, and the second fiber web compensation device is mutually connected with the first conveying curtain, the second conveying curtain, and a pair of hauling wire ropes. The lapping mechanism has the advantages that a lay-up cotton web body presents the bread-shaped effect of the thick middle and the both thin sides, and has perfect improvement function to the quality of downstream non-woven products.

Description

technical field [0001] The invention belongs to the technical field of a cotton web laying device in a complete set of non-woven machinery equipment, and more specifically relates to a web laying mechanism with a compensation function. Background technique [0002] As known in the industry, as a complete set of non-woven machinery and equipment, it mainly includes an opening machine, a carding machine, a cotton feeding machine, a web laminating machine, and a needle punching machine according to the sequence of the process, and the web laminating machine is composed of a frame, a web laying mechanism, and a forming machine. The web mechanism is composed of the web mechanism, which plays the role of laying the non-woven fiber cotton fed by the carding machine onto the web forming curtain corresponding to the bottom. [0003] The net laying mechanism of known net laying machine mainly has two kinds of structural forms, and they are shown in Fig. 1 and Fig. 2 respectively. Tak...

Problems solved by technology

The net-laying trolley 2 is driven by the motor to reciprocate. Under the connection of the traction wire rope 5, the net-laying trolley 1 moves with the movement of the net-laying trolley 2, and the first and second conveying curtains 3 and 4 are connected by a curve in the figure. The illustrated non-woven fiber cotton enters the net in a pinched manner, and the quality of forming or laying the net is better than the previous structure, but when the net laying trolley 2 changes direction or returns at the left and right ends, it will also cause the laying to slow down due to the slowing down of the speed. Cotton nets stacked on the web curtain show the phenomenon that both ends (both sides) are thick and the middle is thin, which hinders the quality of non-woven products after needle punching
