[0002] The fiber web laying machine is an important piece of equipment in textile machinery. It is mainly used to evenly lay fiber webs onto a fiber laying curtain, preparing for subsequent processing steps (such as needle punching and hydroentangling). The laying machine uses a carding mechanism to card the fibers into single fibers, and then the movement of the laying curtain evenly lays the fibers into a web. The continuous movement of the laying curtain ensures a continuous output of fiber webs for use in subsequent processes. In the prior art, a net laying machine with adjustable net height is disclosed in patent announcement number CN219410113U, which includes a base plate: mounting plates are fixedly connected to both the left and right sides of the base plate, four fixing cylinders are fixedly connected to the upper side of the base plate, an adjustment unit is provided on the upper side of the fixing cylinders, mounting blocks are fixedly connected to the outer side of the fixing cylinders, and net laying components are provided on the upper side of the mounting blocks.

[0003] In the nonwoven fabric production process, the height adjustment of the web forming curtain of the web laying machine has a significant impact on product quality. Existing web laying machines with adjustable web forming curtain height (such as those shown in patent CN219410113U) achieve height adjustment of the web forming curtain drive roller by using components such as chutes, sliders, and electric push rods, and utilize rubber plates to seal the chutes to prevent fiber blockage of the sliders. However, some problems still exist in practical use. For example, adjusting the position of the slider and connecting plate can cause the rubber plate to fail to fit and seal the chutes, resulting in an unsatisfactory sealing effect. Fibers may still enter the chutes, making slider movement difficult and affecting adjustment accuracy and efficiency. Furthermore, the inclusion of electric push rods and rubber plates increases the cost of the drive equipment used in the web laying machine. Summary of the Invention
