Abstract

An automatic lifter for carpet tufting machine needle bar consists of flywheel, link on eccentric pin, link block connected with another end of link, needle bar connected with link block vertically, pendulum driven by link block, needle bar fixing block arranged on top of link block, twisted-coil cant hook coupled below link block, whose middle is fixed with needle bar fixing block, transmission bent handle arranged on top of pendulum, one end contacts with upper end of twisted-coil cant hook, another end is fixed connected with medium link block and pressure bar by Connecting board, pressurebar lifter is made up of twisted-coil cant hook coupled below link block and transmission bent handle controlled by pressure bar; needle bar stops at summit instantly while twisted-coil cant hook is automatically uncoupled. It's fast, accurate and efficient, has better quality and less consumption.

Description

technical field [0001] The invention relates to a carpet tufting machine, and an automatic lifting device for a loom needle bar of the carpet tufting machine. Background technique [0002] At present, the carpet tufting machine used in China, whether it is imported from abroad or domestically designed and manufactured, the needle bar in the machine head is driven by the eccentric pin on the transmission flywheel to move up and down to perform tufting action, which is tufting work. When the presser foot plate is pressed down, pressing the woven block tightly, the needle bar of the tufting machine moves up and down continuously, and performs continuous tufting action. When the loom completes one or one pattern, the thread must be cut or moved. When the cloth block is embroidered, the operator should step on the clutch to stop the machine from working. At the same time, the hand wheel must be shaken with the right hand, and the needle bar can be lifted up to the top dead center...
