Light mineral wool fiber felt needling forming device

Abstract

The invention provides a light mineral wool fiber felt needling forming device, belongs to the technical field of mineral wool fiber felt processing setting, and solves the technical problems that during existing needling, relative movement exists between a needling needle and the surface of a raw material, so that the needling needle is easy to break, and the surface of the raw material is scratched. The light mineral wool fiber felt needling forming device comprises a working table, a needling mechanism comprises two vertical plates, the two vertical plates are fixed to the upper side of the working table, a guide plate is fixed between the two vertical plates, a motor is fixed to the upper end of one vertical plate, a U-shaped rod is fixed to the output shaft end of the motor, a driving rod is rotationally connected to the U-shaped rod, and the driving rod is rotationally connected to the working table. A lifting rod is rotatably connected to the lower end of the driving rod, a limiting groove is formed in the limiting plate, the lifting rod is slidably connected with the limiting groove, and a needling assembly is fixed to the lower end of the lifting rod. Compared with the prior art, the needle protection device has the advantages that during needling, the needle and raw materials move synchronously, so that the needle is protected, and the product quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mineral wool fiber felt processing equipment, and relates to a needle-punching forming device, in particular to a light-weight mineral wool fiber felt needle-punching forming device. Background technique [0002] Mineral wool fibers are fibers obtained from mineral rocks with a fibrous structure. For example, asbestos is extracted from mineral fibers. Mineral wool fibers are more and more widely used in many fields, especially in the paper industry. During processing, it is necessary to use acupuncture machine to acupuncture it to make it into shape. The function of the acupuncture machine is to repeatedly puncture the fiber web with barbed needles. The hook will drive the fibers on the surface and sub-surface of the fiber web to move from the plane direction of the fiber web to the vertical direction of the fiber web, causing the fibers to shift up and down, and the fibers that are displaced up and down ...

AI Technical Summary

Problems solved by technology

[0004] Although the acupuncture forming device disclosed in this patent can quickly switch templates, the acupuncture mechanism in the device moves straight up and down. Since the raw material is still in a moving state during the acupuncture action, the needle and the surface of the raw material are instantly punctured. There is relative movement, which causes the puncture needle to break easily, and the surface of the raw material is scratched, which affects the product quality
