Description

[Detailed description of the invention] Carding machine and its setting method The present invention comprises a main cylinder with a hub and a car cylinder cooperating with the hub of said cylinder. along the working path adjacent to the outer surface of the main cylinder to carry out the Carding machine with rotating flat assembly with movable flats The present invention relates to a setting device for thinning.

The invention is particularly suitable for carding cotton, but also for wires containing synthetic fibers. The outside fiber raw material can also be carded by a carding machine.

To ensure an effective carding action, the tip and “flap” of the cylinder hub are It is important to set and maintain a preset air gap between the Typical void space for cotton raw materials is 0. Approximately 127 cm (0.05 inch) On the other hand, for example, the suitable air gap for a certain synthetic fiber is 0.0508 cm (0.02 inch). (inches).

When all parts of the cylinder surface and rotating flats cooperate in the working path, It is possible to obtain an almost uniform air gap between all parts of the cylinder surface and the rotating flat. important, and it manufactures and assembles cylinders and wire crosses and flats. This is achieved by using the appropriate datum when setting It will be done. However, the specific air gaps required for a given operation are currently not available in the field. and is implemented using relatively unsophisticated technology.

The working path of the rotating flat assembly is the movement of the flat by traveling support rollers. is defined by a "flexible bend" on which is supported. flexible bend has a curvature corresponding to that of the cylinder, but in order to obtain the desired air gap, radially spaced from the axis of the cylinder for micro-adjustment along the entire length of the flexible bend. clauses are usually required.

The air gap settings are typically multiple along the working path between the flat and the outside surface of the cylinder. This is done by using a “filler gauge” inserted into the Radial adjustment of the flexible bend between the flat and the cylinder as required This is done along the entire length of the flexible bend to obtain an air gap. The filler gauge is Depending on the characteristics of the work inserted into the gap between the tips of the ear teeth, and the setting work For example, since the air gap measurements differ from worker to worker depending on the method in which the Some workers tend to insert the gauge deeply into the cavity, while others tend to attach it loosely. Therefore, the quality of the setup work varies depending on the worker. Also, the word “flat” Ear wires are typically more flexible than cylinder wires, and set-up is performed by the operator. The configuration work is very dependent on technique and inclination or individual “feel”. varies depending on the worker and is unpredictable.

Adjustments are usually made between cardias called “fixed bends” and flexible bends. Performed at set points (usually 5 points) operating between fixed parts of the machine be done. Once the adjustment is completed, the carding machine will work for a long time. . However, after a certain period of time (especially with flat wires) wear occurs. However, re-polishing is required, so it is necessary to reset the voids taking into account the re-polishing that has been performed. becomes.

Furthermore, newer equipment requires closer air gap settings, thus reducing the setting process. Techniques of workers to perform setup tasks that require less skill It has become necessary to eliminate dependence on tendencies or "feelings".

When a certain type of raw material, e.g. from cotton to synthetic fibers, requires porosity adjustment, different An air gap must be established that allows for According to current technology, this need is not addressed above. Requires a complete resetting operation using a filled filler gauge. this takes time This is a process that involves making carding machines work with different types of raw materials. This means significant "downtime" when changing to Furthermore, individual workers The accuracy of gap setting depends on the technique and care taken in the work.

The invention therefore provides a more reliable initial design of the air gap between the flat and the cylinder. Improved settings that allow you to easily adjust the initial settings when required. The purpose of this invention is to provide a method and apparatus for
