Description

A web laying machine for evenly stacking cotton

Technical Field

The utility model relates to the technical field of textile machinery, in particular to a web laying machine for evenly stacking cotton.

Background Art

A web laying machine is a machine that folds the carded fiber web repeatedly through the web laying machine, and after reaching the expected size and weight, it is stacked and conveyed to the next process. It can be used in conjunction with different types of carding equipment. A web laying machine is generally composed of a frame, a web laying mechanism, and a web forming mechanism. The web laying mechanism consists of a web guide roller, a web laying curtain mounted on the web guide roller, a power transmission device that drives the web laying curtain to operate, and a movable frame also known as a synchronous moving mechanism.

The web laying curtains of the web laying mechanism of the current web laying machine are composed of an upper web laying curtain, a lower web laying curtain and a compensation curtain located between the upper and lower web laying curtains, which cooperate with each other to lay the cotton web on the web forming curtain of the web forming mechanism. The web laying machines currently sold in the domestic market can be divided into reciprocating web laying machines, also called multi-curtain web laying machines, and clamping web laying machines. The reciprocating web laying machines are also called multi-curtain web laying machines. The reciprocating web laying machines have more conveying curtains, including three-curtain web laying machines and four-curtain web laying machines, and each has a variety of structures. The three-curtain web laying machine is currently commonly used in China, and the clamping type also has a variety of structures, such as high-speed three-curtain and two-curtain forms.

The use of a web laying machine can make the width of the folded web not limited by the working width of the carding machine, so as to obtain a web with a large unit area mass, increase the unit area mass of the web, increase the width of the web, adjust the longitudinal and transverse strength ratio of the web, improve the uniformity of the web, and obtain a web structure with fibers of different specifications and colors arranged in layers. Application number: 201720956030.9, discloses a web laying machine for evenly stacking cotton, including a frame, a conveyor belt, a guide wheel, a web laying bucket, a telescopic rod and a sleeve rod, so that the device solves the problem of cotton layer dislocation or wrinkles during the laying work of the existing web laying machine. However, when using this device, since the net-laying bucket is used to lay out the cotton layers layer by layer, the rolling wheel rolls and presses the cotton layers as the net-laying bucket swings, and the net-laying bucket is hinged on the frame, so the swing trajectory of the net-laying bucket is curved. As a result, the length of the rolling wheel may not be sufficient when pressing the cotton layers on both sides, which may easily lead to incomplete pressing of the cotton layers, causing inconvenience to the operator.

Therefore, it is necessary to provide a web laying machine with uniform cotton stacking to solve the above technical problems.
