Chain jacquard

Abstract

The invention provides a chain jacquard machine which includes a frame, a wallboard, a scraping out cutter mechanism and a transmission mechanism. The scraping out cutter mechanism includes an adjusting screw rod, a down base, a scraping out cutter frame plate, a small pull rod and a scraping out cutter, the transmission mechanism includes a drive sprocket, a first adjusting sprocket with two sheds, a tension sprocket and a closed chain, the closed chain external connects with sprocket of the first shed adjusting sprocket, and inner connects with sprockets of the second shed adjusting sprocket, the tension sprocket and the drive sprocket, some eccentric locating holes are distributed on the first and second shed adjusting sprocket, upper end of the adjusting screw rod hinge joints with an eccentric locating hole. The chain jacquard machine provided by the invention has advantages that running of the machine is stability with little impact and lower noise, speed of mainshaft is increased, torquemoment is reduced for applicable to over loading woof and high speed loom, structure of the machine is simple by reducing some components, trouble point and trouble rate are reduced greatly, maintainability of the machine is simple, so the machine is low in price and has lower maintain cost, producting efficiency is increased.

Description

technical field [0001] The invention relates to a jacquard machine, in particular to a chain type jacquard machine. Background technique [0002] At present, the most widely used is a lifting rocker type jacquard machine, referring to Fig. 3 and Fig. 4, its working principle is: drive the double eccentric wheel 22 to transmit power to the double connecting rod 23 through the transmission shaft 21, and the connecting rod 23 The eccentric movement drives the lifting rocker 24 to reciprocate, thereby driving the upper seat 25, the adjusting screw 26, the lower seat 27, the broach frame plate 28, and the small pull rod 29 to realize the reciprocating movement of the broach 30, thereby satisfying the jacquard function of the jacquard machine . The disadvantages of lifting rocker jacquard machine are: [0003] 1. When the equipment is in operation, the lifting rocker 24 performs reciprocating motion, and the acceleration at high and low positions is very large, resulting in rela...

AI Technical Summary

Problems solved by technology

The disadvantages of lifting rocker jacquard machine are:

[0003] 1. When the equipment is running, the lifting rocker 24 performs reciprocating motion, and the acceleration is very large at the high and low positions, resulting in relatively large impact and noise, which is not suitable for high-speed work requirements

[0004] 2. The transmission shaft 21 directly drives the double eccentric wheel 22 to rotate without speed reduction, so the speed is low and the required torque is large, which is not suitable for heavy-duty work requirements

[0005] 3. The structure is complex and the cost of parts is high, resulting in a high price of the whole machine; at the same time, the parts are too large and too many, the space structure is limited, some bearings cannot fully guarantee the five-year life, and the failure points and failure rates of the corresponding components are greatly increased , so the equipment maintenance is complex and the maintenance cost is high
