Cotton filling gun for glass fiber puffing

Abstract

The invention relates to a cotton filling gun for glass fiber bulking, and relates to the technical field of glass fiber bulking equipment, the cotton filling gun comprises a seat body, a shell and an air cylinder fixed on the seat body, the seat body and the shell are fixed and sealed, and a threading hole for glass fibers to penetrate through is formed in the seat body in the length direction of the seat body in a penetrating mode; the air cylinder is used for abutting against the glass fiber in the threading hole, one end of the seat body is located in the shell and is chamfered, the end, located in the shell, of the seat body and the inner wall of the shell form a high-pressure air outlet, and the seat body is provided with a partition plate which is connected with the shell in an inserted mode and matched with the shell in a sliding mode; the partition plate divides an inner cavity of the shell into an air storage cavity and an air guide cavity in the conveying direction of the glass fibers, the partition plate and the inner wall of the shell are arranged in a sealed mode, a plurality of vent holes are circumferentially formed in the partition plate with the threading hole as the center, and an air source is communicated with the end, close to the seat body, of the shell and ventilates air into the air storage cavity. According to the invention, high-pressure gas is uniformly dispersed, so that the puffing dispersion effect on the glass fiber is improved.

Description

technical field [0001] The present application relates to the technical field of glass fiber expansion equipment, in particular to a cotton filling gun for glass fiber expansion. Background technique [0002] Glass fiber is filled in the car muffler as a kind of automobile sound-absorbing material, and its sound-absorbing effect is closely related to the dispersion degree of glass fiber. The glass fiber is filled in the automobile muffler after puffing and dispersion, which plays the role of heat preservation and noise reduction. Generally, glass fiber penetrates into the cotton filling gun, and a high-pressure air outlet is formed inside the cotton filling gun, and high-pressure gas is connected to the surface of the cotton filling gun. The muzzle direction of the cotton filling gun runs in the direction of the muzzle, and continuously expands and disperses the glass fibers. After a certain amount of glass fiber is expanded, the cylinder at the end of the cotton filling gu...

Problems solved by technology

[0003] However, in the process of using the existing glass fiber cotton filling gun, the glass fiber is often dispersed unevenly, which affects the heat preservation and noise reduction effect after the glass fiber is filled into the automobile muffler.
