A kind of unginned cotton slagging-off motor-vibro screen
Technical field
The present invention relates to textile machine apparatus field, especially, is a kind of unginned cotton motor-vibro screen of resistance to mechanical fatigue.
Background technology
The effect of scutching cotton carries out mixed cotton, opener, all cotton, removal of impurities to raw cotton.Beat according to first pine is rear, many pines are few to be beaten, caducous few broken, and how row is large assorted, evenly returns less, well-mixed PROCESS FOR TREATMENT principle, carries out different raw cotton different disposal.The packed bulk density of raw cotton and cotton ginning method are relatively closer to dissolution, the packed bulk density hour of raw cotton, hired roughneck should less or Beater Speed should be slow; When packing tight, suitably should increase the speed of opening or cleaning point or quickening hired roughneck, to keep certain degree of opening.Impurity in raw cotton is the object that scutcher directly processes, general containing many should beating of mixing more, should beat less less containing assorted.
In scutching cotton technique, the sieve that electricity consumption generally can be made to drive carries out removing process to the impurity in raw cotton, traditional electronic sieve is generally centrifugal to be arranged on motor or to adopt the mode of mechanical connection to drive said screen, feature due to sieve is vibration, and machinery is responsive especially to vibration, vibration is easy to make machinery produce tired wearing and tearing.
Summary of the invention
In order to solve the 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 stop 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 is arranged on the screen cloth in described framework, described framework is horizontally set in the impurity box body of a upper end open, described framework is connected with described impurity box body elasticity by least three Flexible Connectors, the periphery of described framework is at least evenly equipped with two pieces of permanent magnets, the inwall of described impurity box body is respectively arranged with the electromagnet adapted with described permanent magnet, described electromagnet is independently controlled by a power-supply controller of electric.
As preferably, the bottom of described screen cloth is provided with the bar magnet perpendicular to screen plane, and the bottom of described impurity box body is provided with the electric induction coil coordinated with described bar magnet, and described electric induction coil is electrically connected with a pulse power.
As preferably, bottom described impurity box body, be provided with the air-exhausting filtering device of air pump and filter screen formation.
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 in described framework one by one and repels or attract, described framework is made to 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, enable the vibration that described framework is carried out in vertical direction, owing to driving the driving force of described framework from magnetic fields, decrease mechanical connection, make whole device reliable and stable work.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Consult Fig. 1 and Fig. 2, in the present embodiment, the screen cloth 210 that this unginned cotton slagging-off motor-vibro screen comprises framework 200 and is arranged in described framework 200, described framework 200 is horizontally set in the impurity box body 100 of a upper end open, described framework 200 is connected with described impurity box body 100 elasticity by least three Flexible Connectors 300, the periphery of described framework 200 is at least evenly equipped with two pieces of permanent magnets 220, the inwall of described impurity box body 100 is respectively arranged with the electromagnet 110 adapted with described permanent magnet 220, described electromagnet 110 is independently controlled by a power-supply controller of electric.
Above-mentioned unginned cotton slagging-off motor-vibro screen, the bottom of described screen cloth 210 is provided with the bar magnet 230 perpendicular to screen cloth 210 plane, the bottom of described impurity box body 100 is provided with the electric induction coil 120 coordinated with described bar magnet, described electric induction coil 120 is electrically connected with a pulse power, described electric induction coil 120 makes described bar magnet produce vertical vibration under the pulse current effect of the described pulse power, makes the vibration that described screen cloth 210 can carry out in vertical direction.
Above-mentioned unginned cotton slagging-off motor-vibro screen, the air-exhausting filtering device 150 of air pump and filter screen formation is provided with bottom described impurity box body 100, the floating impurity of the vibrated rear generation of the unginned cotton in screen cloth 210 is taken away in time 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, the binding force to described framework 200 can be adjusted, making 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, random or self-defining mode drives described electromagnet 110 to work one by one, described electromagnet 110 produces the permanent magnet 220 in described framework 200 one by one and repels or attract, described framework 200 is made to 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 the vibration that described framework 200 can be carried out in vertical direction.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included in protection scope of the present invention.
