DX268V intelligent two-for-one doubling machine

Abstract

The invention discloses a DX268V intelligent two-for-one doubling machine, and belongs to the technical field of two-for-one doubling machine equipment. A single two-for-one doubling unit is driven bya transmission motor and a stepping motor to operate, the transmission motor drives a transmission belt through a motor belt wheel to drive three spindles to rotate at a high speed so as to achieve the purpose of yarn twisting, and each motor in a lathe body is controlled by a PLC control module and is connected with a control panel host in a lathe head through a 485 communication line to be independently controlled to be started and shut. When abnormal conditions such as yarn breaking occur, automatic shutdown is achieved through detection of a speed yarn detector, unnecessary idling lossesare reduced, and the effect that single-spindle control starting and shutting operation is convenient is achieved; the stepping motor ensures the synchronism of a friction roller and an overfeeding driving wheel; a yarn collecting opening is located over the position among an upper porcelain eye of a front striping finger, an upper porcelain eye of a left-rear striping finger and an upper porcelain eye of a right-rear striping finger, the consistency of the tension of the three yarns is guaranteed, the tension of a transmission belt controls a tensioning wheel through a tensioning tension spring, and therefore the spindle speed is kept consistent by the transmission belt through the enough tensioning wheel.

Description

technical field [0001] The invention belongs to the technical field of doubling and paralleling equipment, and in particular relates to a DX268V intelligent doubling and paralleling machine. Background technique [0002] Traditional doubling machine: [0003] 1. Long-distance belt transmission, because the number of spindles of the two-for-one twister is relatively long, generally around 288 spindles, and the long-distance transmission error is large, which requires high quality of the dragon belt. [0004] 2. Traditional doubling machines are generally divided into two-in-one and three-in-one. Because of the dragon-belt linear transmission, it is difficult to achieve consistent tension in yarn plying. Ply yarn will be equipped with a cutter device to cut off other strands of yarn, which will cause winding on the spindle, causing environmental pollution in the workshop and troublesome cleaning. [0005] 3. The safety system of equipment operation is low. Because the tradit...

[0004] 2. Traditional doubling machines are generally divided into two-in-one and three-in-one. Because of the dragon-belt linear transmission, it is difficult to achieve consistent tension in yarn plying. Ply yarn will be equipped with a cutter device to cut off other strands of yarn, which will cause winding on the spindle, which will cause environmental pollution in the workshop and troublesome cleaning

[0005] 3. The safety system of equipment operation is low. Because the traditional doubling machine adopts the structure of collective transmission, when a certain station breaks the yarn and needs jointing, because all parts are in motion, it is easy to happen when the operation is improper or careless. security incident
