Abstract
Description
Technical Field
[0001] The utility model relates to the field of polyester yarn production, in particular to a twisting disc for producing polyester pre-oriented yarns. Background Art
[0002] Twisting is to make the two ends of the straightened yarn rotate relative to each other, so that the single fibers on the surface of the yarn form a spiral shape relative to the axis of the yarn. Twisting can make the inclined fibers produce centripetal pressure on the axis of the yarn when the yarn is subjected to a tensile external force, so that there is a certain friction resistance between the fibers, which is not easy to slip, thereby increasing the strength of the yarn, and ultimately improving the ability of the yarn to resist external forces during the weaving process and the use of textiles, and having better durability. For short fibers, the main function of twisting is to make the fibers gather together to form yarns with certain physical and mechanical properties, so that they can withstand various external forces during weaving and the use of textiles and have certain durability.
[0003] The twisting disc is an indispensable part of the twisting equipment, which is assembled on the spindle rod for use. However, the existing twisting disc and the spindle rod are not convenient to assemble. Most of the time, the twisting disc is pinned to the spindle rod through a rigid pin structure. When disassembling, the pin needs to be taken out, but the removal process is very laborious and inconvenient, which affects the use of the device.
[0004] Therefore, in order to solve the deficiencies in the prior art, a twisting disk for producing polyester pre-oriented yarns with a simple structure needs to be designed. Utility Model Content
[0005] The utility model provides a twisting disc for producing polyester pre-oriented yarns to solve the problems of the prior art.
[0006] The purpose of the utility model can be achieved through the following technical scheme: A twisting disk for producing polyester pre-oriented yarn comprises: a twisting disk body, a spindle rod and a positioning piece, the lower end of the twisting disk body is provided with an insertion rod, the lower end of the insertion rod is provided with a slot, the inside of the spindle rod is vertically provided with a plug hole for accommodating the plug rod and a slider hole connected to the plug hole, the slider holes are arranged in parallel, the positioning piece comprises an insertion block, a spring and a turntable, the insertion block is slidably arranged in the slider hole, the insertion block is provided with a protrusion matching the slot, the spring is sleeved on the insertion block, the turntable is rotatably arranged on the outside of the spindle rod, and arc-shaped push blocks are symmetrically arranged in the turntable, the outer end of the insertion block is located between the arc-shaped push blocks and the outer end of the insertion block is provided with an arc portion.
[0007] As a further improvement, the insertion rods and the insertion holes are arranged in four groups in a 90-degree circular array.
[0008] As a further improvement, the two groups of arc-shaped push blocks constitute a limiting member, and the limiting member and the arc-shaped push blocks are arranged in a 90-degree circular array in four groups.
[0009] As a further improvement, a push rod is provided on the outer side of the turntable.
[0010] As a further improvement, the slider hole is provided with an annular limiting portion 1, the insert block is provided with an annular limiting portion 2, and the spring is arranged between the annular limiting portion 1 and the annular limiting portion 2.
[0011] Compared with the prior art, the twisting disc for producing polyester pre-oriented yarn of the utility model has the following beneficial effects:
[0012] The turntable is rotated to make the arc-shaped push block contact the arc-shaped part of the plug block, thereby pushing the plug block to move along the inside of the slider, and then the plug rod of the twisting disc body is inserted into the insertion hole of the spindle rod, and the turntable is rotated in the opposite direction. The plug block moves outward under the action of the spring, and the protrusion on the inside of the plug block is inserted into the slot of the plug rod, thereby locking the spindle rod to the twisting disc body. At the same time, the outside of the plug block is located between the two groups of arc-shaped push blocks, which can prevent the turntable from rotating arbitrarily. When the twisting disc body needs to be disassembled, it only needs to be rotated to move the plug block inward and then the protrusion exits the slot of the plug rod. The operation is simple and the locking is stable. BRIEF DESCRIPTION OF THE DRAWINGS
