The working method of the dustproof system for roller grinding comprises the following steps:
the first step: when a roller is polished by a roller grinder, a second motor is controlled to work, the output end of the second motor drives a rotary plate to rotate, a multidirectional rotary piece is driven to perform circular motion in the rotary process of the rotary plate, a connecting frame is driven to perform reciprocating swinging motion by taking the joint of the connecting frame and a connecting seat as an axis in the motion process, piston push rods at two ends of the connecting frame respectively perform reciprocating motion in a blowing guide sleeve and a suction guide sleeve, when the piston push rods move in the blowing guide sleeve towards the direction of a second gas pipeline, air flow is generated by the movement of the piston, the air flow flows towards the direction of the roller grinder through the end part of the second gas pipeline, metal dust is blown towards the direction of a chip adsorption assembly by the air flow forming thrust, and meanwhile, the air force generated by the second gas pipeline and used for blowing the roller grinder also has the effect of cooling the roller grinder;
and a second step of: when the air flow in the second air conveying pipeline blows metal dust to the direction of the chip adsorption assembly and the piston push rod in the air suction guide sleeve moves to the direction far away from the first air conveying pipeline, the air flow generated by the movement of the piston forms suction force, the metal dust blown by the second air conveying pipeline is further assisted to move to the direction of the chip adsorption assembly, and the air blowing guide sleeve and the piston push rod in the air suction guide sleeve cooperate to guide the polished metal dust to the chip adsorption assembly for adsorption;
and a third step of: when the polishing position of the roller changes, the first motor is controlled to work, the output end of the first motor rotates to drive the driving screw rod to rotate, so that the driving block is driven to move on the driving screw rod and the limiting rod, and the driving block drives the wind power guiding assembly to move until the first gas transmission pipeline and the second gas transmission pipeline in the wind power guiding assembly correspond to the polishing position of the roller;
fourth step: the wind power guiding assembly controls the metal dust generated by polishing to blow to the electromagnet rotary drum, and simultaneously controls the electromagnet rotary drum to be electrified to generate magnetic adsorption force, and the metal dust generated by polishing the roller also has magnetic force due to friction force, so that the metal dust is adsorbed on the surface of the electromagnet rotary drum, and the metal dust is prevented from scattering everywhere;
fifth step: when the metal dust is adsorbed by the electromagnet rotary drum, the third motor is controlled to work, the electromagnet rotary drum rotates towards the direction of the scrap scraping plate, the electromagnet rotary drum contacts with the edge of the side end of the scrap scraping plate, and the metal dust and the dust adsorbed by the surface of the electromagnet rotary drum are scraped onto the scrap scraping plate;
sixth step: the scraped metal scraps and dust fall into the recycling cavity above the scrap recycling bin through the inclined scrap scraping plate, after the scrap in the recycling cavity above is filled, the scrap recycling bin is controlled to rotate 180 degrees by controlling the fourth motor to work, the scrap in the recycling cavity above is dumped into the scrap collecting box, the recycling cavity at the lower end of the scrap recycling bin is rotated to the upper side originally, and the scraped metal scraps and dust on the electromagnet rotating drum are continuously collected.
The above at least one technical scheme adopted by the embodiment of the invention can achieve the following beneficial effects:
firstly, when roll grinder polishes the roll, can produce a large amount of metal dust and metal piece scatter everywhere, if do not handle it, metal dust entering device inside can cause the damage to the device, when carrying out the roll and polish, control second motor work, the second motor output drives the rotor plate rotation, the rotor plate rotation in-process drives multidirectional rotating member and carries out circular motion, drive the link in the motion process and carry out reciprocating swing motion with the junction of connecting seat for the axle, the piston push rod at link both ends carries out reciprocating motion in blowing uide bushing and the uide bushing that breathes in tandem respectively, the piston push rod is in blowing uide bushing and when moving to second gas transmission pipeline direction, the motion of piston produces the air current, the air current flows through the tip of second gas transmission pipeline to roll grinder's direction, the air current forms thrust and blows the metal dust to the direction of piece adsorption component, when the piston push rod in the uide bushing that breathes in is in to keeping away from the direction removal of first gas transmission pipeline simultaneously, the air current that the piston motion produced forms the suction, further auxiliary is by the direction removal of the metal piece that the second gas transmission pipeline was blown from the adsorption component, the direction removal of the die dust that the uide bushing and the direction of the die dust that the direction of the second gas transmission pipeline was carried out in the die grinder have the direction of the second gas transmission pipeline to the effect of the dust that the dust of the roll is formed simultaneously.
And secondly, because the two piston push rods reciprocate in the blowing guide sleeve and the air suction guide sleeve respectively, the first air conveying pipeline and the second air conveying pipeline can both produce the effect of air suction and air blowing, instability of metal dust flow can be caused, the flow direction of air flow is limited by the check valve, the outward pushing air flow generated by the piston push rods is controlled by the check valve arranged at the end part of the first air conveying pipeline and can not be discharged through the check valve, but is discharged through the air outlet above the first air conveying pipeline, the inward sucking air flow generated by the piston push rods is controlled by the check valve, only the outward blowing air flow can be discharged through the check valve communicated above the second air conveying pipeline, and the outward blowing air flow can not be discharged through the check valve communicated above the second air conveying pipeline, so that the effect that the end part of the first air conveying pipeline only outputs the air flow sucked into the first air conveying pipeline and the end part of the second air conveying pipeline only outputs the air flow blown outwards into the second air conveying pipeline is realized.
Third, when the wind-force direction subassembly control is polished the metal dust that produces and is blown to the electro-magnet rotary drum, control electro-magnet rotary drum circular telegram produces magnetic attraction, and the metal dust that the roll was polished and is produced also has magnetic force owing to frictional force's reason, thereby is adsorbed at the surface of electro-magnet rotary drum to prevent that the metal dust from scattering everywhere.
Fourth, when metal dust is adsorbed by the electromagnet rotary drum, the third motor is controlled to work, the electromagnet rotary drum rotates towards the direction of the scrap scraping plate, and the electromagnet rotary drum contacts with the side end edge of the scrap scraping plate to scrape the metal dust and dust adsorbed on the surface of the electromagnet rotary drum onto the scrap scraping plate.
Fifthly, scraped metal scraps and dust fall into the recycling cavity above the scrap recycling bin through the inclined scrap scraping plate, after the scrap in the recycling cavity above is filled, the scrap recycling bin is controlled to rotate 180 degrees by controlling the fourth motor to work, the scrap in the recycling cavity above is dumped into the scrap collecting bin, the recycling cavity originally located at the lower end of the scrap recycling bin is rotated to the upper side, and the scraped metal scraps and dust on the electromagnet rotary drum are continuously collected.
The air blowing end and the air suction end of the wind power guiding assembly can be controlled to be adjusted along with the polishing position change of the roll grinder through the driving displacement assembly, when the polishing position of the roll changes, the first motor is controlled to work, the output end of the first motor rotates to drive the driving screw to rotate, so that the driving block is driven to move on the driving screw and the limiting rod, and the driving block drives the wind power guiding assembly to move until the first air conveying pipeline and the second air conveying pipeline in the wind power guiding assembly correspond to the polishing position of the roll.
