High power twister

Abstract

The invention relates to a twisting device in the textile fiber twisting field. It is a high power twisting device, its character: it is composed of outer ingot device, inner ingot device, middle ingot device, package support mechanism, yarn retreating and guiding device and outer ingot cylinder mechanism, where the ingot rod of top rotary magnet base of the inner ingot device is supported on the top of the bottom ingot rod of the outer ingot device through the bearing, the static support base of the middle ingot device is supported on the ingot rod of top rotary magnet base through the bearing, the package support component of the package support mechanism on the top end of the ingot rod of top rotary magnet base through the bearing, the ingot-end cord rod and mouth are actively covered on the top end of the package support component, the outer ingot cylinder mechanism is outside the inner ingot device and the outer ingot cylinder is fixed with the frame. It has characters of rotation-rotation yarn feeding and 4 twisting rounds, simple structure, etc.

Description

technical field [0001] The invention relates to a twisting device in the field of textile fiber twisting, in particular to a high-magnification twisting spindle. Background technique [0002] The known two-for-one twist spindle, that is, the spindle turns once and adds two twists to the yarn, has been widely used in the spinning industry at present. Its main defects are: to process yarns of different raw materials, two-for-one twisting spindles with different structural sizes must be used. Spindle, that is, a structure type of two-for-one twisting spindle can only process yarns of a certain kind of raw material, which obviously limits the application of two-for-one twisting spindles to a certain extent, and increases manufacturing and production costs; in order to achieve high productivity, two-for-one twisting The twisting spindle must adopt a high working speed (generally 10000-15000rpm), which will increase energy consumption, aggravate machine vibration and noise, incre...

Problems solved by technology

Its main defects are: to process yarns of different raw materials, two-for-one twisting spindles with different structural sizes must be used. Spindle, that is, a two-for-one twisting spindle with a structure can only process a certain kind of raw material yarn, which obviously limits the application of two-for-one twisting spindles to a certain extent, and increases manufacturing and production costs; in order to achieve high productivity, two-for-one twisting The twisting spindle must adopt a high working speed (generally 10000-15000rpm), which will increase energy consumption, aggravate machine vibration and noise, and increase the design and manufacturing requirements and manufacturing cost of the spindle; when the two-for-one twisting spindle is working, the yarn produces an atmosphere, and the yarn High thread tension, easy to break, affect product quality, and require a special yarn tension regulator; produce fly, pollute the working environment

Its defects mainly include: when the spindle is twisting, the yarn package and the spindle cover in the spindle have to rotate at high speed with the spindle, the moment of inertia is large, and because the yarn package is difficult to achieve precise dynamic balance, the working speed of the spindle is still very high. High, it will inevitably produce greater vibration and noise; twisting efficiency needs to continue to improve

[0004] In recent years, people have paid attention to the development of high-power twisting machinery. Zhejiang Rifa Company has also proposed the idea of ​​a four-fold twisting spindle. However, its structure is too complicated to manufacture and use in actual production.
