Description

Technical Field

[0001] The utility model relates to the technical field of web laying machines, in particular to a pressure roller of a web laying machine. Background Art

[0002] The web laying machine is an important part of a complete set of non-woven product production equipment. First, the wire mesh is transferred upward by the ascending conveyor, and the wire mesh is laid on the horizontal conveyor by the back-and-forth swinging of the swinging web laying machine head. Finally, the fluffy wire mesh is compacted by the pressure roller. The traditional installation of the pressure roller adopts bolt fixing. If the distance between the pressure roller and the horizontal conveyor is adjusted, the bolts need to be removed to move the pressure roller down or up, and then fixed again. This method of adjusting the pressure roller spacing is time-consuming and laborious, and the efficiency is low. At the same time, when the pressure tube is rolling and pressing the wire mesh, some wire mesh will be entangled on its surface. If it is not cleared in time, it will become more and more, and finally affect the rolling and pressing of the wire mesh by the pressure roller. Utility Model Content
