A kind of unginned cotton slagging-off motor-vibro screen
Technical field
The present invention relates to the textile machine apparatus field, especially, is a kind of unginned cotton motor-vibro screen of anti-mechanical fatigue.
Background technology
The effect of scutching cotton is that raw cotton is carried out mixed cotton, opener, all cotton, removal of impurities.According to beating behind the pine earlier, many pines are few to be beaten, caducous few broken, and how row is big assorted, evenly returns less, and well-mixed PROCESS FOR TREATMENT principle is carried out different raw cotton different disposal.The packed bulk density of raw cotton and ginning method are closer to dissolution, the packed bulk density of raw cotton hour, the hired roughneck should be less or hired roughneck's speed suitable slow; Pack when tight, the suitable speed that suitably increases opening or cleaning point or quickening hired roughneck is to keep certain degree of opening.Impurity in the raw cotton is the object that scutcher is directly handled, and generally contains assorted many suitable beat more, containing assorted few should lack dozen.
In scutching cotton technology, the sieve that electricity consumption is driven is removed processing to the impurity in the raw cotton, traditional electronic sieve is general centrifugally to be arranged on the motor or to adopt the mode of mechanical connection to drive the sieve vibration, because the characteristics of sieve are vibrations, and machinery is responsive especially to vibration, and vibration is easy to make machinery to produce tired the wearing and tearing.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of unginned cotton slagging-off motor-vibro screen, this unginned cotton slagging-off motor-vibro screen can be stopped mechanical friction.
The technical solution adopted for the present invention to solve the technical problems is:
This unginned cotton slagging-off motor-vibro screen comprises framework and the screen cloth that is arranged on the described framework, described framework is horizontally set in the impurity box body of a upper end open, described framework is hinged by at least three Flexible Connectors and described impurity box body, the periphery of described framework is evenly equipped with two permanent magnets at least, be respectively arranged with the electromagnet that adapts with described permanent magnet on the inwall of described impurity box body, described electromagnet is set up with a power-supply controller of electric respectively and independently is electrically connected.
As preferably, the bottom of described screen cloth is provided with vertically disposed bar magnet, and the bottom of described impurity box body is provided with the electric induction coil that cooperates with described bar magnet, and described electric induction coil is electrically connected with a pulse power.
As preferably, described impurity box body bottom is provided with the air-exhausting filtering device that air pump and filter screen constitute.
As preferably, described Flexible Connector is the adjustable vapour-pressure type extension sleeve of air pressure inside.
The invention has the advantages that:
Described electromagnet produces the permanent magnet on the described framework one by one and repels or attraction, make described framework produce vibration in the horizontal direction, described electromagnetic induction coil makes described bar magnet produce vertical vibration under the pulse current effect of the described pulse power, make described framework can carry out vibration on the vertical direction, come the self-magnetic field effect owing to drive the driving force of described framework, reduced mechanical connection, made whole device reliable and stable work.

The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
Consult Fig. 1 and Fig. 2, in the present embodiment, this unginned cotton slagging-off motor-vibro screen comprises framework 200 and the screen cloth 210 that is arranged on the described framework 200, described framework 200 is horizontally set in the impurity box body 100 of a upper end open, described framework 200 is hinged by at least three Flexible Connectors 300 and described impurity box body 100, the periphery of described framework 200 is evenly equipped with two permanent magnets 220 at least, be respectively arranged with the electromagnet 110 that adapts with described permanent magnet 220 on the inwall of described impurity box body 100, described electromagnet 110 is set up with a power-supply controller of electric respectively and independently is electrically connected.
Above-mentioned unginned cotton slagging-off motor-vibro screen, the bottom of described screen cloth 210 is provided with vertically disposed bar magnet 230, the bottom of described impurity box body 100 is provided with the electric induction coil 120 that cooperates with described bar magnet, described electric induction coil 120 is electrically connected with a pulse power, described electromagnetic induction coil 120 makes described bar magnet produce vertical vibration under the pulse current effect of the described pulse power, makes described screen cloth 210 can carry out vibration on the vertical direction.
Above-mentioned unginned cotton slagging-off motor-vibro screen, described impurity box body 100 bottoms are provided with the air-exhausting filtering device 150 of air pump and filter screen formation, the floating impurity that produces after unginned cotton in the screen cloth 210 is vibrated is in time taken away by described air-exhausting filtering device 150, prevents air pollution.
Above-mentioned unginned cotton slagging-off motor-vibro screen, described Flexible Connector 300 is the adjustable vapour-pressure type extension sleeve of air pressure inside, by regulating the air pressure of described vapour-pressure type extension sleeve, can adjust the binding force to described framework 200, make the Oscillation Amplitude of described framework 200 adjustable.
The operation principle of above-mentioned unginned cotton slagging-off motor-vibro screen:
Described power controller controls power supply in order, at random or self-defining mode drive 110 work of described electromagnet one by one, described electromagnet 110 produces the permanent magnet 220 on the described framework 200 one by one and repels or attraction, make described framework 200 produce vibration in the horizontal direction, described electromagnetic induction coil 120 makes described bar magnet produce vertical vibration under the pulse current effect of the described pulse power, makes described framework 200 can carry out vibration on the vertical direction.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included in protection scope of the present invention.
