The purpose of the present invention is to provide a thin metal mesh punched anti-wrinkle inlet, that is, to improve the existing structure due to the excessive length formed between the conveying end and the inlet structure between the upper conveying wheel and the lower conveying wheel. This distance makes the conveying end easy to squeeze, crease or jam when conveying the thin metal mesh to this distance, and affect the uneven mesh punching of the thin metal mesh. It provides a way to make the metal thin The mesh can be more smoothly conveyed and punched, and it can avoid the thin metal mesh squeezing, wrinkles or jamming of the metal thin mesh punching anti-wrinkle inlet.

According to the above-mentioned objective, the present invention proposes an anti-wrinkle inlet for punching metal thin nets. The inlet is mainly provided with a first oblique convex body extending outward from one side of a bottom knife seat, and is fixed on the bottom knife A second oblique convex body extending outward from one side of a pressing plate above the seat, so that the first oblique convex body and the second oblique convex body correspond up and down to form the inlet, and the inlet extends in and close to the top and bottom A conveying end is formed between a corresponding upper conveying wheel and a lower conveying wheel to shorten the distance between the conveying end and the material inlet between the upper conveying wheel and the lower conveying wheel.

Furthermore, the first oblique convex body of the bottom knife seat extends from above on one side of the bottom knife seat from bottom to top to the outside to form an oblique cone-shaped body.

Furthermore, the second oblique convex body of the pressure plate extends from the bottom of one side of the pressure plate from top to bottom to the outside to form an oblique cone.

Furthermore, a conveying path is formed between the pressing plate and the bottom knife seat, and the conveying path extends along the material inlet and is intersected.

Furthermore, the inlet is used for conveying the thin metal mesh into and out of the conveying channel.

The present invention can achieve the following advantages through the above technology:

1. The present invention passes through the inlet formed between the first oblique convex body and the second oblique convex body, and the inlet extends into and close to the upper and lower corresponding upper and lower conveying wheels To shorten the distance between the thin metal mesh at the conveying end and the feed opening between the upper conveying wheel and the lower conveying wheel, so that the thin metal mesh is separated from the upper conveying wheel and the lower conveying wheel. The intermediate conveying end is conveyed to the inlet, thereby forming a guiding effect for the thin metal mesh.

2. The present invention enables the thin metal mesh to be completely pressed by the first oblique convex body and the second oblique convex body, as well as the pressure plate and the bottom knife seat, and can prevent the thin metal mesh from squeezing, wrinkling or When the material is clamped and the upper tool is used to punch the bottom tool, the mesh of the thin metal mesh can be uniform, so the quality of the thin metal mesh is very good.
