Abstract

An air door and a large-suction-nozzle air door of a combined yarn trap of an automatic winder in spinning production are characterized in that a cavity between a yarn trap yarn suction channel and an air door front shell and a cavity between the yarn trap yarn suction channel and an air door rear shell are negative-pressure cavities which are mutually sealed, a yarn trap front suction opening is sequentially connected with a suction pipe and a suction nozzle, a yarn trap rear suction pipe is communicated with the negative-pressure cavities through connecting pipes, and therefore opening and closing of the yarn trap air door is controlled; a large-suction-nozzle air door control mechanism comprises a cam shaft which rotates to change the angle position of an air door swing bar through a cam, then a four-bar mechanism formed by the air door swing bar, a connecting bar and an air door connecting bar transmits the angle position change to the air door, and the air door can be located at different work positions in the splicing circulation. The air door and the large-suction-nozzle air door of the combined yarn trap of the automatic winder have the advantages that the large-suction-nozzle air door is used for controlling opening and closing of the yarn trap, the structure is simple and reliable, and the phenomena that broken barrels are generated and the yarn splicing process is affected are avoided.

Description

The compound type yarn trap air door of automatic winder and large suction nozzle air door

Technical field

The present invention relates to field of textile machinery, the compound type yarn trap air door of the automatic winder that is specifically related to use in caused by spinning industrial production and large suction nozzle air door.

Background technology

In the normal doff process of automatic winder, yarn package speed is very high, and velocity variations is also larger, so yarn has the possibility of fracture at any time.The yarn trap of installing on machine can siphon away effectively because of the formed small fragment hard waste of yarn breakage, prevents that small fragment hard waste is brought into bobbin and forms bad cylinder, also has the functions such as flyings on cleaning yarn and impurity simultaneously.But when automatic winder proceeds to while splicing cyclic process, yarn trap can impact Yarn splicing process again, and therefore, yarn trap often needs to have switching function.For this reason, traditional yarn trap arranges switching air door between suction inlet and yarn, with the action of magnet control air door.But the effect of playing due to air door is to stop rather than close, and traditional yarn trap still has certain influence to Yarn splicing process in actual use.

At present, the yarn trap of import automatic winder is all arranged on air door the centre that yarn trap is inhaled yarn channel substantially, with this, realize the contract fully that yarn trap is inhaled yarn channel, but mostly still adopt electromagnet to control separately its action, therefore manufacturing cost is higher, and electromagnet easily damages, cause yarn trap disabler and produce bad cylinder.

Summary of the invention

The object of the invention is to overcome the defect in above-mentioned background technology, design a kind of compound type yarn trap air door and large suction nozzle air door of automatic winder.

The present invention is by taking following technical measures to realize: the designed automatic winder compound type yarn trap air door providing is characterised in that with large suction nozzle air door:

Suction inlet (7) after large suction nozzle suction yarn channel (16) side of air door rear housing (6) arranges a yarn trap, while is suction inlet (9) before the large suction nozzle of air door front case (1) is inhaled the other correspondence position of yarn channel (16) yarn trap is set, and corresponding breather port (17) is set on the correspondence position of air door (2), sealing band (8) sealing for breather port (17), thus, the cavity between the suction yarn channel (15) of yarn trap and air door front case (1), air door rear housing (6) forms airtight negative pressure cavity mutually; Connected sucking pipe (10), suction nozzle (11) successively on suction inlet (9) before yarn trap, suction inlet after yarn trap (7) is connected negative pressure cavity by taking over (5), with this, controls the switching work of yarn trap air door;

Suction nozzle airdoor control mechanism comprises camshaft (12) greatly, be fixed on the cam (13) on camshaft (12), the rotation of cam (13) changes the angle position of air door fork (14), air door fork (14), connecting rod (3), throttle linkage (4) form space four bar linkage mechanism and are delivered to air door (2), realize thus the different control position of air door (2) in the cyclic process of splicing.

The present invention's advantage is compared with prior art yarn trap air door and large suction nozzle air door to carry out integrated design, utilizing large suction nozzle air door to control yarn trap opens and closes, simple and reliable for structure, do not adopt magnet control, avoided damaging because of electromagnet the phenomenon that produces bad cylinder or affect Yarn splicing.

The specific embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

The present invention has carried out integrated design to automatic winder yarn trap air door and large suction nozzle air door: in large suction nozzle air door cavity, having built one has the yarn trap air door chamber of leakproofness with former cavity, utilizes air door revolution action to intersect to open and close large suction nozzle to inhale yarn channel and yarn trap suction yarn channel simultaneously; When the air door designing can guarantee large suction nozzle suction yarn channel unlatching, yarn trap suction yarn channel is closed, and when large suction nozzle suction yarn channel is closed, the unlatching of yarn trap suction yarn channel.

Work schedule to air door is adjusted, and it is not only possessed inhale yarn change, idle is energy-conservation, work grips, the function of exhaustion refuse yarn, also need in the cyclic process of splicing, not affect Yarn splicing, can in normal doff process, performance catch yarn function again.

Large suction nozzle air door has adopted swing arm roller cam mechanism, has designed the shape of air door, and in air door bottom, corresponding position has breather port, also calculates and has revised cam:

When normal doff, the large suction nozzle between air door front case and air door rear housing is inhaled yarn channel and is sealed (see figure 5) by air door, and now, after the breather port before yarn trap on suction inlet, air door, yarn trap, suction inlet is in breakthrough status, and yarn trap is inhaled yarn channel and opened; When splicing the suction yarn change of circulation, air door turns to maximum position, and large suction nozzle is inhaled yarn channel and is opened to maximum (see figure 6), and now before yarn trap, after suction inlet and yarn trap, the suction of the yarn trap between suction inlet yarn channel is sealed by air door; In the idle of the circulation of splicing, when energy-conservation, air door turns to minimum position, and large suction nozzle is inhaled yarn channel and opened 1/4(and see Fig. 7), now, before yarn trap, after suction inlet and yarn trap, the yarn trap passage between suction inlet is sealed by air door; When the work of the circulation of splicing grips and exhausts refuse yarn, air door turns to midway location, and large suction nozzle is inhaled yarn channel and is opened to half (see figure 8), and now, before yarn trap, after suction inlet and yarn trap, the suction of the yarn trap between suction inlet yarn channel is still sealed by air door.
