Embodiment Construction

[0020] exist Figure 1 to Figure 6 In the shown schematic diagram of the present invention, the web forming machine frame 1 is a frame frame, and a net curtain 2 is laid on the upper surface of the frame, and the tow is received above the web forming machine, and the wire is formed in the web forming machine frame. The lower part of the bundle and fiber web is equipped with a main suction mechanism and a secondary suction air channel mechanism. The main suction area is where the tow falls to the web forming machine, and the secondary suction area is to enable the fiber web to transition smoothly on the mesh curtain. , the main suction mechanism, the secondary suction air channel mechanism are connected with the fan trench. The main suction mechanism includes the main air duct bracket, annular sleeve, main air duct air volume regulating valve, arc slide rail, slider, ring gear, main air duct, toothed belt, motor, gear, windshield, nylon gang and perforated plates. The main ai...

Abstract

The invention discloses a web former with a rotatable main air duct. The web former mainly comprises a main air suction mechanism and an auxiliary air suction duct mechanism, wherein the auxiliary air suction duct mechanism is connected with the main air suction mechanism through an annular sleeve. According to the invention, a pair of pre-pressing rollers and a whole set of heating device provided for the pre-pressing rollers are omitted, the energy consumption is reduced, the labor resources are reduced, the production cost is reduced, the equipment structure is simple, and the operation is safe and convenient. Under the condition that a machine frame of the web former is fixed, the main air duct can freely rotate within the range of 0-45 degrees, so that a certain included angle is formed between the main air suction duct and the cloth feeding direction, and the longitudinal and transverse strength ratio of a product can be effectively reduced; and the horizontal width of an air suction area can be changed, and then the breadth of the final product is changed, so that one web former can produce products with various breadths, and the manufacturing and labor cost is saved.

Description

technical field [0001] The invention patent belongs to the field of nonwovens and relates to a web forming machine. Background technique [0002] The frame of the web forming machine is a frame-shaped frame, and a net curtain is laid on the upper surface of the frame, and the tow is received above the web forming machine, and a main suction air duct is arranged at the lower part of the tow and fiber net in the web forming machine frame And the auxiliary air duct, the main air suction area is the position where the tow falls to the web forming machine, the auxiliary air suction area is to make the fiber web transition smoothly on the mesh curtain, the main air suction air channel and the auxiliary air suction air channel The fan is connected to the trench, and the static eliminator is fixed on the upper part of the frame of the web forming machine and the corresponding position of the auxiliary suction air duct. There is a front guide walking platform in the running direction...
