Abstract

The utility model relates to a godet wheel with double V-shaped grooves, which comprises a godet wheel body (41), wherein a circle of large V-shaped grooves (42) are formed in the godet wheel body (41), and a circle of small V-shaped grooves (43) are formed in the bottom of each large V-shaped groove (42). According to the godet wheel with the double V-shaped grooves, the small V-shaped groove is additionally formed in the bottom of the V-shaped groove of the godet wheel, the core wire is limited in the small V-shaped groove, and a supporting point is added for the core wire to swing left and right, so that the transmitted shaking force is smaller, the stability of the core wire is improved, and the quality of a finished product of the core-spun yarn is effectively guaranteed.

Description

double-V-shaped groove godet wheel

Technical Field

The utility model relates to a godet roller with double V-shaped grooves, and belongs to the technical field of textile machinery accessories.

Background

The core spun yarn is also called composite yarn or covering yarn, and is a new type of yarn formed by combining two or more kinds of fibers. The core spun yarn is generally spun by using synthetic fiber filaments with good strength and elasticity as core filaments and wrapping short fibers such as cotton, wool and viscose fibers together for twisting. The core-spun yarn has the excellent performances of both filament core yarn and short fiber covering. The core-spun yarn has rich varieties, is widely applied in the textile industry, and has wide development prospect.

In the textile industry, core-spun yarns are usually spun using a ring spinning machine, and a godet unit is an essential accessory for the ring spinning machine to spin the core-spun yarns. Traditional godet roller device includes the fixed bolster and sets up the godet roller part in the fixed bolster both sides, and the fixed bolster comprises long nut and end support, and the godet roller part includes the bolt axle and installs the bearing in bolt axle one end and the godet roller of seting up the blind hole, and the screw axle other end is connected on the long nut of fixed bolster, and the bearing is installed in the blind hole of godet roller. In the production process of the core-spun yarn, the core wire swings left and right to a certain degree (the left and right swing amplitude is about 55 degrees), and because certain deviation exists between the center of the wire handle and the center of the godet wheel in actual operation, the left and right swing of the core wire and the angle of the V-shaped wheel groove of the godet wheel are larger, the core wire shakes, and the quality of the core-spun finished yarn is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a godet wheel with double V-shaped grooves, wherein a small V-shaped groove is additionally arranged at the bottom of a large V-shaped groove of the godet wheel, a core wire is limited in the small V-shaped groove, and a supporting point is added for the left-right swinging of the core wire, so that the swinging force transmitted downwards is smaller, the stability of the core wire is increased, and the quality of a finished product of core-spun yarn is effectively ensured.

The technical scheme adopted by the utility model for solving the problems is as follows: the utility model provides a two V type groove godet rollers, it includes the godet roller body, be provided with the big V type groove of round on the godet roller body, big V type bottom of the groove portion is provided with the little V type groove of round.

Optionally, the included angle between the left side wall and the right side wall of the large V-shaped groove is 55-65 degrees.

Optionally, an included angle between the left side wall and the right side wall of the large V-shaped groove is 60 degrees.

Optionally, the included angle between the left side wall and the right side wall of the small V-shaped groove is 20-40 degrees.

Optionally, an included angle between the left side wall and the right side wall of the small V-shaped groove is 30 degrees.

Optionally, the depth of the small V-shaped groove is less than 1 mm.

Compared with the prior art, the utility model has the advantages that:

1. according to the core-spun yarn winding device, the small V-shaped groove is additionally arranged at the bottom of the large V-shaped groove of the godet wheel, the core yarn is limited in the small V-shaped groove, and the fulcrum is added for the left-right swinging of the core yarn, so that the transmitted swinging force is smaller, the stability of the core yarn is improved, and the quality of a finished product of the core-spun yarn is effectively ensured;

2. the height of the small V-shaped groove is not easy to be too high, and is preferably controlled to be less than 1mm, so that the small V-shaped groove can be prevented from winding wires and yarns, and is not easy to clean.
