Description

Technical Field

[0001] The utility model relates to the technical field of net laying machines, in particular to a width adjustment structure of a net laying machine. Background Art

[0002] When producing non-woven fabrics, what comes out of the carding machine is generally a single-layer fiber web. It is usually necessary to lay the single-layer fiber web into a non-woven fabric blank with a certain width and thickness. This process is called laying, which is mainly completed by a laying machine.

[0003] Currently, a Chinese patent application, CN213113793U, discloses a width adjustment device for a cross-lapper. The device specifically relates to the technical field of cross-lapper equipment, comprising a workbench with a roller rotatably mounted in the middle of the workbench, brackets fixedly mounted on either side of the workbench's top, a fixed platform fixedly mounted on top of each bracket, a fixed column fixedly mounted in the middle of the fixed platform's inner cavity, and a rocker rotatably mounted on the fixed column. The utility model utilizes a threaded rod and a threaded block. Rotating the threaded rod controls the left and right movement of the threaded block on the threaded rod, thereby controlling the left and right movement of a slider. The threaded block and slider are fixedly connected to control the movement of a transmission rod. Due to the rotational connection between the transmission rod and the rocker, the two sliders can be controlled to move simultaneously in opposite or opposite directions, thereby controlling the distance between two limit plates, thereby adjusting the width of the web during web laying. This allows for width adjustment according to customer needs during web laying, thereby expanding the applicability of the cross-lapper.

[0004] In actual production, it is found that the width of the laid net can be adjusted by adjusting the limit plate, but the height of the limit plate is different. When the thickness of the laid net is higher than the limit plate, the limit plate loses its limiting purpose, causing the laid net to deviate. Therefore, we proposed a width adjustment structure of the lay machine to solve the above problem. Utility Model Content
