Introduction of the Gil Box Machine

Author:QINSUN Released in:2023-06 Click:99

One of the most important pieces of equipment in the long fiber processing system, such as in worsted spinning, is the gill box machine. Because the fiber directional parallelism and uniformity of the slivers produced by the roller carding machine do not match the spinning criteria, some of them still have the “hook” phenomenon and cannot be spun directly in the long-staple spinning system. Therefore, the top is processed and reshaped using a gill box machine.

The carding process of the gill box machine is a crucial step in the wool spinning process. The purpose is to improve the degree of parallel stretching of the fibers and to improve the structure of the sliver by gathering. The working condition of the gill box is very closely related to the performance and quality of the worsted spinning mill.

The Main Tasks of Gill ProcessMultiple merging and stretching improve the homogeneity of medium and long sliver parts; Directional parallelism and fiber separation are further increased by the combination of needles, and hooks and curls are removed. The fibers are mixed evenly and yarn quality is maintained through repeated merging and drawing. Remove all minor impurities and short hair. Types of gill boxes

In the worst case, many different types of gill machines are used in today\'s wool spinning processing system.

They are classified according to the mode of transmission of the needle plate and the device used to control the fibers in the drawing section: screw gill machines, chain Gill machines, rotary gill machines, toothed roller gable machinesInline and pinboard-free drawing machines are the most common.

According to the installation arrangement of the pinboard, it can be divided into three types: open type, cross type and half-cross type.

There are many types of Gilling machines, but their composition is about the same and mainly consists of feeding mechanism and Stretching mechanism, pressure mechanism, winding mechanism and automatic leveling device.

Feeding mechanism

It is mainly composed of belt table, belt roller, belt bar and guide belt mounting plate etc., on which several wool tops be merged to the Unto mix and improve evenness of the wool surface.

Outfeed Mechanism

It mainly consists of front, middle and rear rollers, compaction rollers and needle comb boxes. Among them, the needle row mechanism is more complicated and includes parts such as needle plate, screw rod, beater, pressure plate and guide rail. The function is to pull the combined raw materials finely and at the same time improve the straightening parallelism of the fibers.

Pressure Mechanism

The two tasks of pressing the front roller and raising the comb box can each be done by rebuilding the valve.

Winding Mechanism

It mainly consists of a winding plate, a small pressure roller, a can chassis and a can and its function is to produce a sliver that conforms to certain specifications.

Automatic levellingung device

In the wool processing plant, it is usually equipped with a final gill machine equipped with an automatic leveling device, which is purely mechanical. The main function is to automatically change the draw ratio after detecting the thickness change of the fed sliver, which actively and effectively improves the uniformity of the output sliver and improves the quality of the finished sliver.

Gill box process

The process of the gill box is similar to that of the drafting system, except that the carding mechanism has been added to the drafting system.

Multiple slivers are drawn from the can and stacked side-by-side on the rod guide table to form fiber layers before being sent after the run the rod guide roller or the bead roller get into the rear roller.

After the sliver has been pulled forward a little from the middle roller, it gets into the transversesneedle plate area and is pulled by the front roller through the upper and lower rollers in a circular motion needle plate retaining straps to complete drawing and carding. In order to achieve progressive carding, the upper and lower needle boards gradually penetrate the fiber layer.

The fibers drawn and output by the front roller are collected in a sliver by the bundler and the compaction roller, and finally wound up and regularly placed through the winding disc and the inclined winding tube into the output can.

Error causes and solutions

Possible causessolutions Uniformity unevenThe stretch ratio or the front gauge of the card is set too large;
Poor connection;
Front roller pressure is unstable;
Needle plate and roller lint or are defective. Adjust the stretching process;
Specification connector;
Strengthen the correction of equipment.Uneven weightIncorrect adjustment from feeding slEiter or broken sliver and missing roots;
Roller pressure is uneven. Adjust the number of forage roots and strengthen the tour;
Adjust the roller pressure. Hair grain increases. needle board, steel needle, belt hook bent, steel needle defect, etc.;
The draw ratio of the head needle and the second needle is too large;
Upper channel is not clean and smooth. waitg reinforce;
Adjust the draw ratio;
Clean carefully. Splitter hairLess oil, lower moisture absorption, high static electricity, poor fiber cohesion;
The upper channel hangs wool.
Fiber length is too long;High friction on fiber surface;
