The utility model has the characteristics of novel structure, practicality are stronger.
Description
Technical Field
The utility model belongs to big circular knitting machine accessory field, especially single face machine accessory relates to an improved generation big circular knitting machine cylinder.
Background
The fire breaking grooves at the upper end of the outer diameter surface of the lower needle cylinder of the existing single-sided machine all adopt rectangular grooves, and the rectangular fire breaking grooves have the problems of long heat treatment time and easy deformation in the process of processing the needle cylinder because two groove edges are right angles.
Disclosure of Invention
In order to solve the problems, the utility model provides an improved generation circular knitting machine cylinder, it can not only shorten the time of thermal treatment effectively, but also has the more superior advantage of resistance to deformation performance, the utility model has the characteristics of novel structure, practicality are stronger.
In order to achieve the purpose, the utility model adopts the following specific technical measures: an improved cylinder of a circular knitting machine, which is characterized in that,
the outer diameter surface of the cylinder is milled with a plurality of vertical needle grooves which are used for guiding rail grooves when a knitting needle works in vertical operation;
the upper end of the outer diameter surface of the cylinder body is milled with a circle of fire breaking groove which is sunken towards the inner diameter direction, the width of the upper groove and the lower groove of the fire breaking groove is 6 mm-8 mm, and the depth of the groove is 8 mm-12 mm;
furthermore, the included angle between the lower groove wall of the fire breaking groove and the outer diameter surface of the barrel body is a right angle, and the outer edge of the upper groove wall of the fire breaking groove is milled into a cambered surface through a lathe;
the outer edge of the top surface of the cylinder body protrudes upwards to form a nozzle mouth, and the nozzle mouth is milled with a plurality of transverse needle grooves;
a plurality of screwing holes are drilled upwards in the bottom surface of the cylinder;
the lower end of the inner diameter surface of the cylinder body is milled with a circle of convection groove which is sunken towards the outer diameter direction.
The beneficial effects of the utility model reside in that, it has novel structure, the stronger characteristics of practicality.
The present invention will be further described with reference to the accompanying drawings and examples.
