Description
Technical field
The present invention relates to a kind of water jet looms equipment, particularly a kind of weft insertion device for water jet looms.
Background technology
Water jet looms due to efficiency high, weave fabric quality good, always by city's place identity, but, selecting the quantity of latitude and select the weft yarn of latitude to require, compared to Rapier looms and air-jet loom, water jet looms truly has self limitation, due to this circumscribed existence, the D number of weft yarn is confined in 1: 4 scope.On water jet looms, weft insertion device is its key component, in the use procedure of water jet looms, the weft yarn that Pumping mechanism wefting insertion can draw is in the selection of kind or thickness, normally 2 kinds, the structure also had can be increased to 4 kinds, but, prerequisite is that these different weft yarns also have in size close at composition, because the hydraulic pressure that same set of weft insertion device produces is certain.Along with the development of textile technology, new fabric is more and more higher to the multifarious requirement of weft yarn, and a lot of fabric weft yarn number requires many, and thus due to the restriction of weft insertion device, water jet looms in long-term use, does not catch up with the development of technology gradually.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of weft insertion mechanism of water jet loom by two-stage cam mechanism driving three groups of independence water pumps is provided.
Technical scheme of the present invention is: a kind of water jet looms three pump many sprays weft insertion device, comprise the three groups of water pumps be arranged in frame, and the cam mechanism to connect with water pump, described cam mechanism comprises the one-level cam mechanism connected with first group of water pump, second group of water pump, the secondary cam mechanism connected with the 3rd group of water pump; Wherein, one-level cam mechanism comprises about two cam swings being set to " L ", " Γ " shape respectively distributed, the one-level cam slidingly contacted between two cam swings and with one end of two cam swings, the other end of two cam swings connects with water pump respectively; Secondary cam mechanism comprises the cam swing being set to " Γ " shape, and be positioned at the top of cam swing and the secondary cam slidingly contacted with one end of cam swing, the other end of cam swing connects with the 3rd group of water pump; One-level cam and secondary cam are by link gear synchronous rotary, and the corner of cam swing is coupling in frame.
Preferably: described actuating unit comprises power input bent axle, and the opening shaft coordinated with bent axle, two power output shafts coordinated with opening shaft, power output shaft connects with cam mechanism.
Preferably: the electromagnetic steering valve connected with water pump is 2 enter 4 and go out electromagnetic steering valve.
Preferably: described cam is set to eccentric structure.
Preferably: the other end of described cam swing is connected with the pump rod of water pump by connecting rod piece.
Preferably: described cam swing and cam contact place are set to a rotating annular sleeve.
Beneficial effect of the present invention is: reasonable in design of the present invention, and complete machine oscillation is little, long service life, and new Pumping mechanism, different hydraulic pressure can be produced, increase and select number of latitude amount, 12 weft yarns can be had at most to select; The increase of wefting insertion power, requirement for weft yarn is relaxed, the D number of weft yarn is not being confined in 1: 4 scope, like this, weft yarn is in use just unrestricted, expands the scope of weaving cotton cloth, pumping system can produce different wefting insertion power, like this, the requirement for yarn reduces, and kind and the thickness of weft yarn are unaffected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
A kind of water jet looms three pump many sprays weft insertion device, comprise the three groups of water pumps be arranged in frame, and the cam mechanism to connect with water pump, described cam mechanism comprises the one-level cam mechanism connected with first group of water pump, 1, second group of water pump 2, the secondary cam mechanism connected with the 3rd group of water pump 3; Wherein, one-level cam mechanism comprises about two cam swings 4 being set to " L ", " Γ " shape respectively distributed, the other end of one-level cam 5, two cam swings 4 slidingly contacted between two cam swings 4 and with one end of two cam swings 4 connects with water pump 1,2 respectively; Secondary cam mechanism comprises the cam swing 4 being set to " Γ " shape, and be positioned at the top of cam swing 4 and the secondary cam 6 slidingly contacted with one end of cam swing 4, the other end of cam swing 4 connects with the 3rd group of water pump 3; One-level cam 5 and secondary cam 6 are by link gear synchronous rotary, and the corner 10 of cam swing 4 is coupling in frame.Described cam is set to eccentric structure.The other end of described cam swing 4 is connected with the pump rod 8 of water pump by connecting rod piece 7.Described cam swing 4 is set to a rotating annular sleeve 9 with cam contact place, can reduce the friction between cam and cam swing 8, increase its service life.
Adopt 2 to enter 4 and go out the electromagnetic steering valve solution electromagnetic steering valve problem of taking up space more.Traditional electromagnetic steering valve 1 enters 2 and go out, and is applicable to the two spray of single pump.If nozzle increases, the quantity of the electromagnetic steering valve of needs also increases gradually.If nozzle quantity reaches 8 sprays, that employing 1 is entered 2 and is gone out electromagnetic steering valve, will with 9.And the position of wallboard is limited on the left of water jet looms.Adopt 2 enter 4 go out after, only need 3.
All-purpose nozzle size is large, and two spraying nozzle spacing are generally at about 16mm.And wefting insertion traverse is limited, opening is limited, and what add waterline itself does parabolic motion, so wefting insertion is limited in limited space.When ensureing that nozzle needle is constant, sprinkler body and nozzle being supportted seat and unites two into one, save space, ensure adjustability again.
During work, actuating unit drives one-level cam 5 and secondary cam 6 synchronous rotary, thus drive cam swing 4 to rotate around its corner 10, one end of cam swing 4 swings up and down, the other end of cam swing 4 swings, thus drives water pump to fetch water work by brace 7, simultaneously, hydraulic pressure can be controlled by regulating Compress Spring, thus control waterline and weft yarn.
