Secondary shaping device and method for outlet of fiber rod forming machine

Abstract

The invention discloses a secondary shaping device and method for an outlet of a fiber rod forming machine. The secondary shaping device comprises a mounting frame and a secondary shaping mechanism; and the secondary shaping mechanism comprises a mounting plate, a secondary shaping cylinder and a secondary shaping mold. The secondary shaping mold is installed at the outlet of the fiber rod forming machine, and secondary shaping is conducted on a fiber rod stretching out of the outlet of the forming machine, so that the problem that expansion is prone to being generated only through one-time forming is avoided, and the production size precision of the fiber rod is improved; and furthermore, the secondary shaping mold is directly pressed in the secondary shaping cylinder through a single-side pressing assembly, so that fiber rods with different diameters can cause the diameter change of the secondary shaping mold to result in the phenomenon that the secondary shaping mold and a primary shaping mold are not coaxial, namely, mounting adjusting holes need to be formed in a mounting plate, the coaxiality between the secondary shaping mold and the primary shaping mold is conveniently adjusted to adapt to the diameter change of the fiber rod, and the production size precision of the fiber rod is further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fiber rod preparation, and in particular relates to a secondary setting device and a setting method for the outlet of a fiber rod forming machine. Background technique [0002] Fiber sticks are commonly known as perfume cores, oil storage integrated cotton, filter cotton cores, which are fiber bundles formed by combining many fine porous fiber threads. Fiber sticks are mainly used for natural and slow release of air purification and some products that need water diversion and filtration functions. Vacuumizers, microcomputer sweepers, etc.), medical (laboratory pipettes, oxygen concentrators, humidification bottles, etc.) and other industries; [0003] The existing cotton core rod preparation method is mainly the thermoforming drawing method, for example, a cotton core rod forming machine with the application number of 201810404266.0, which includes the following technical scheme: the forming part include...

AI Technical Summary

Problems solved by technology

[0004] According to the above-mentioned analysis of the prior art, the applicant found that the cotton wicks coming out of the forming section were often directly transported to the cutting section, and did not perform other processing work on the cotton wicks coming out of the forming section; and the applicant also found that In the preparation process of the cotton core rod in the prior art, the diameter of the cotton core rod is only controlled at the forming part, but the applicant found that the cotton core rod will expand after it comes out of the forming part, and after understanding the processing site, the general design This problem has been considered when forming the outlet diameter of the forming part, and generally speaking, the diameter requirements of the cotton core rod are not very strict, so there is a problem of low dimensional accuracy in the preparation of the cotton core rod in the prior art
