Description

Technical Field

[0001] This utility model relates to the field of acupuncture machine technology, specifically to a net feeding mechanism for an acupuncture machine. Background Technology

[0002] A needle punching machine is a blanket-forming device that compresses and needles refractory fiber blanket blanks of a certain thickness to form refractory fiber blankets. It uses needles with triangular or other shaped cross sections and barbs on the edges to repeatedly puncture the fiber web. The fiber web that comes off the cross-web or air-laid web forming machine is very loose when it is fed into the needle punching machine. It only has a certain strength due to the cohesion between the fibers, but the strength is very poor. When multiple needles puncture the fiber web, the barbs on the needles will drive the fibers on the surface and subsurface of the fiber web to move from the plane of the fiber web to the vertical direction of the fiber web. This causes the fibers to shift up and down, and the fibers that shift up and down will compress the fiber web, causing the fibers in the fiber web to come together and be compressed.

[0003] A utility model application with application number 202420688354.9 discloses a feeding device for a pre-needling machine, belonging to the technical field of feeding devices. It includes: a frame; a feeding roller, a lower conveyor curtain, and an upper conveyor curtain mounted on the frame; the feeding roller and the upper conveyor curtain are positioned above the lower conveyor curtain; the lower conveyor curtain is arranged at an angle; and the upper conveyor curtain is positioned to one side of the feeding roller via a lifting mechanism. This utility model adds an upper conveyor curtain to the feeding mechanism of the pre-needling machine, which can pre-compress thick fiber webs, making the web thinner and allowing it to enter more evenly between the feeding roller and the lower conveyor curtain, thus solving the problem of water ripples on the fabric surface. The upper conveyor curtain is raised and lowered via a lifting mechanism, which can meet different usage needs and improve the applicability of the equipment. In the aforementioned prior art, the feeding mechanism of the needle punching machine cannot limit the fiber web according to the width of different fiber webs, which can easily cause the fiber web to shift during the conveying process, thereby affecting the needle punching effect of the fiber web. Utility Model Content

[0004] In order to solve the problem that the existing needle punching machine's feeding mechanism cannot limit the fiber web according to different fiber web widths, which easily leads to the displacement of the fiber web during the conveying process and thus affects the needle punching effect, the purpose of this utility model is to provide a feeding mechanism for a needle punching machine.
