Abstract

The invention relates to a combined type spinning frame carbon fiber bottom cradle, which is characterized in that a rubber ring bottom cradle is redesigned and is composed of two parts being combined with each other, wherein the part A is a support mounting part and the part B is a bearing bottom rubber ring rotating part; a section of straight part of the part B has a length of 3-5 millimeters, a curve part which is connected to the straight part has a corresponding length of 21-19 millimeters, and a distance from the highest point of the curve part to the front edge of the straight part is 8-11 millimeters; a distance from the highest point of the curve part to the tail end of the rubber ring bottom cradle is correspondingly 16-13 millimeters; a height difference between the curve part and the straight part is correspondingly 4-3.1 millimeters; the total height of a boot-shaped part is 26.25-5 millimeters; the total width of the boot-shaped part is 20-420 millimeters; a mounting slot which is matched with the part A is left in the middle of the boot-shaped part; the mounting slot has a depth of 20-3 millimeters and a width of 3.5-22 millimeters; and the material of the bottom cradle is a plastic casting material such as nylon or carbon fiber, and the like.

Description

technical field [0001] The invention relates to a combined carbon fiber lower pin of a spinning frame, which relates to a drafting part in a drafting mechanism of a spinning frame. Background technique [0002] Spinning frame, as a universal spinning machine in the world, has become one of the indispensable machines in people's life; at present, the lower apron pin (hereinafter referred to as are lower pins) are basically formed by cold drawing, some of which have been improved and have achieved better results during use, but these lower pins are cold drawn first and then followed up without exception. The process of electroplating chromium or electroplating nickel at the end of processing will inevitably lead to lower precision of the lower pin due to the influence of machining accuracy in the processing process, which will affect the quality of spinning, and electroplating will also seriously affect the environment. Carbon fiber upper pins have been widely used in the tex...
