CN201102997Y - Roller of cotton combing machine - Google Patents

Abstract

The utility model discloses a roller of a carding machine, which uses the theory of a fan to arrange a plurality of fan blade-shaped scrapers at the two ends of an upper roller and a lower roller of the carding machine. The scrapers are arranged in a radial shape along the radial direction and vertical to the end face of the roller. Airflow is produced at the scrapers when the upper roller and the lower roller run at a high speed, which can blow away the cotton concentrated around the roller, a cotton stripping roller and a doff wallboard, thus preventing the phenomena that short fibers concentrated around the two ends of the upper roller, the lower roller and the cotton stripping roller can be brought into slivers to form thick slivers and cause uneven product quality if the short fibers are not cleaned off for a long time. With the roller, the quality of the slivers is improved and the labor intensity of textile workers is relieved.

Description

Card Roll

technical field

The utility model belongs to the field of textile machinery, in particular to a carding machine roll.

Background technique

At present, no matter whether the carding machines at home and abroad are used for spinning cotton or chemical fiber, there is a phenomenon of accumulation of short fibers at both ends of the upper and lower rolls, and around the stripping rollers. Flowers will be brought into the sliver to form a thick sliver, resulting in uneven sliver. Now mainly rely on the car operator to regularly clean these places, which increases the labor intensity of the car operator and causes greater trouble to the user.

Contents of the invention

The utility model provides a carding roll, which solves the troublesome problem that the current carding rolls, stripping rollers and doffer wallboards rely on manual cleaning for flower collection.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions to achieve:

A card roll, comprising an upper roll and a lower roll, is characterized in that at least one scraper blade is provided on the end faces of the two ends of the upper roll and the lower roll.

In the technical solution of the present invention, it also has the following technical features: the scraper on the end surface of the roll is arranged radially, and the scraper is perpendicular to the end surface of the roll.

In the technical solution of the utility model, it also has the following technical features: multiple scrapers on the same end face are evenly arranged radially.

In the technical solution of the utility model, it also has the following technical features: the scraper is in the shape of a fan blade, and an airflow is generated at the scraper when the upper and lower rollers are running at high speed, and the airflow can blow away the rollers, stripping rollers and doffers Set flowers around wall panels.

In the technical solution of the present invention, it also has the following technical features: three scrapers are arranged on each end surface of the roll, and the angle between the scrapers is 120°.

Compared with prior art, advantage and positive effect of the present utility model are:

The roller of the carding machine of the utility model utilizes the principle of a fan, and a plurality of blade-shaped scrapers are arranged at both ends of the upper and lower rollers of the carding machine, and the scrapers are radially arranged and perpendicular to the end face of the roller, When the upper and lower rollers are running at high speed, airflow is generated at the scraper. This airflow can blow away the flowers around the rollers, stripping rollers and doffer wallboards, avoiding the two ends of the upper and lower rollers, the cotton stripping rollers and the doffer wallboards. If the accumulated short fibers are not cleaned for a long time, they will be brought into the sliver to form a thick sliver, resulting in uneven sliver, thereby improving the quality of the sliver and reducing the labor intensity of the operator.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Shown in Fig. 1 is the structural representation of the utility model carding machine roll;

Shown in Fig. 2 is the plan view of upper roller;

Among them: 1. Doffer; 2. Cotton stripping roller; 3. Upper roller; 31. Scraper; 4. Lower roller; 5. Doffer wallboard; 6. Three-roller wallboard; 7. Collecting flowers.

Detailed ways

A roll on a carding machine, comprising an upper roll 3 and a lower roll 4, because the gap between the doffer 1, the stripping roller 2, the upper roll 3 and the lower roll 4 on the carding machine is easy to form a collection Flower 7, three scrapers 31 are arranged radially on each end surface of the two ends of the upper roll 3 and the lower roll 4, and the scrapers are arranged radially and evenly on the circumferential end faces of the rolls, and the angle between the scrapers and the scrapers is It is 120°, and the blade is perpendicular to the end face of the roll.

The scraper 31 is in the shape of a fan blade. When the upper roller 3 and the lower roller 4 are running at high speed, an airflow is generated at the scraper. This airflow can blow away the upper roller 3, the lower roller 4, the stripping roller 2, the doffer 1, and the doffer wall. The flowers 7 around the board 5 and the three-roller wallboard 6.

The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model in other forms. Any skilled person who is familiar with this profession may use the technical content disclosed above to change or remodel it into an equivalent change. Equivalent embodiment. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model without departing from the content of the technical solution of the utility model still belong to the protection scope of the technical solution of the utility model.
