Description
Technical field
The present invention relates to a kind of left Weft inserting device of high speed rapier towel loom, belong to rapier towel loom picking motion and change
Into technical field.
Background technology
According to China Textile Machinery association《Textile Machinery Industry " 13 " develops instruction》Analysis, Chinese fabric manufacture equipment are opened
Hair should further agree with the development trend of following New Weaving Technique, towards modularization, versatility, high quality, high-speed and high-efficiency, ring
The directions such as guarantor are developed.Wherein differentiation loom, extraordinary loom are following prior development directions.Development meets extraordinary loom needs
High-performance terry cloth loom, big jacquard loom, carpet loom, adapts to the needs of textile industry product restructuring, can be weaving
Mechanical Manufacturing Enterprises bring extensive development opportunity.
Towel is one of necessity indispensable in people's daily life.With the improvement of people's living standards, to hair
The demand of towel is also significantly rising.Towel current actual amount in China's is 1-1.2 bars for each person every year, and developed country reaches every
Annual more than 10 of people.If we reach 2 from 1 every year per capita, domestic manufacturer will have little time to produce, and reach 3-5
Bar, then can supply falls short of demand.The daily necessities such as towel, bath towel city field boundary is extremely huge, this huge towel by class knop cloth market,
Development for China's terry cloth loom provides vast market prospect.
Rapier towel loom in current rapier towel loom field, mainly two kinds of patterns, one kind are bent axle beatings, connect
The middle low speed rapier towel loom of bar wefting insertion；One kind is Cam Beating-up Mechanism, the high speed arrow shaft towel of connecting rod, cam or propeller wefting insertion
Loom.Middle low speed rapier towel loom is with 747 types, and based on 736 types, speed is generally below 200 revs/min, and price is generally 70,000
Member or so is following；The import of high speed rapier towel loom is with G9200, GT-MAX, and based on R88 types, speed generally at 400 revs/min, is sold
Valency is generally more than 400,000 yuan, and domestic imitated high speed rapier towel loom price is generally also more than 260,000.
The rapier towel loom of two kinds of patterns of the above, the price difference of home-made machine have reached nearly 200,000 yuan.In recent years due to city
Key element is there occurs many changes, as the costs such as labor wage, raw material, logistics, management, finance are all going up, middle low speed arrow shaft
Terry cloth loom faces the test of costs of production and operation, and high speed rapier towel loom is too expensive.So a speed is developed 330
Rev/min, high speed rapier towel loom of the price at 150,000 yuan or so, it has also become city's field boundary there is an urgent need to a kind of type.Develop this
One key mechanism of kind type is the Weft inserting device for adapting to run at high speed.
The Weft inserting device of low speed rapier towel loom is mainly double leval jib wefting insertion and six-bar linkage wefting insertion in domestic at present, to open
Put formula, it is easy to maintenance, cost is cheap.Defect is that rapier transmission box part will add beating load with slay swing,
Limit loom speed rising；The rapier transmission box gear structure big, open with nylon rack back lash, cotton dust easily rest on
On nylon rack, the consumption of wefting insertion is added, also limit the raising of speed.And the Weft inserting device of high speed rapier towel loom is all
It is enclosed in babinet, it is fixed, either spatial linkage is used, or cam is used, otherwise carried out using propeller
Wefting insertion, the accuracy of manufacture, manufacture cost is all very high, can meet that high speed rapier towel loom runs at high speed.But maintenance is very troublesome.
Based on this, propose the present invention.
