[0015] Working principle: When crushing plastic waste, first put the plastic waste into the funnel, start the motor, and the output end of the motor rotates to drive one of the crushing rollers to rotate through the belt. After one of the crushing rollers rotates, it can drive one of the gears to rotate, and the rotation of the gear drives another gear to rotate, and then it can drive the other crushing roller to rotate, so that the two crushing rollers can rotate toward the middle, and then the plastic waste can be crushed. After one of the crushing rollers rotates, it can drive the rotating rod to rotate. After the rotating rod rotates, it can drive the bottom of the driving rod to move up and down, so that the screen frame can move up and down, so that the crushed The unqualified waste will be screened and the unqualified waste will move upward with the bottom of the driving rod. When the discharge port is aligned with the guide sleeve, the unqualified waste at the bottom of the screen frame will fall into the inside of the feed guide nozzle through the guide sleeve, and because the output end of the motor can drive the upper rotating shaft to rotate through the belt after the rotation, the rotating shaft can drive the conveyor belt to transmit after the rotation, and then drive the feeding plate to transmit, and then the unqualified waste can be transmitted to the discharge guide nozzle, and fall into the two crushing rollers through the discharge guide nozzle for crushing again, and then there is no need to transport the unqualified waste to the screening device, so the transportation time can be saved, and then the waste recovery efficiency can be improved;

[0016] When the piston moves upward, the one-way valve one closes and the one-way valve two opens, and the air in the collecting barrel is sucked away through the suction pipe, thereby generating an air pressure difference in the collecting barrel. Therefore, the suction force generated by the air pressure difference can be transmitted to the inside of the vacuum head two and the vacuum head one through the connecting pipe, thereby sucking away the dust, thereby preventing the dust in the working space from being scattered.

[0017] When the dust inside the collection barrel needs to be discharged, the switch valve at the interface between the pressure-stabilizing tank and the air outlet connecting pipe is opened. At this time, the high-pressure air inside the pressure-stabilizing tank will enter the interior of the mounting shell through the air outlet connecting pipe, thereby driving the impeller to rotate, which can drive the rotating column to rotate. After the rotating column rotates, it can drive the mounting frame to rotate. After the mounting frame rotates, it can drive the fixed cylinder to rotate. After the fixed cylinder rotates, it can drive the sliding column to rotate, thereby driving the scraper to rotate, and then the scraper can be used to scrape the dust on the inner wall of the collection barrel and discharge it through the discharge pipe.

[0018] The present invention provides a plastic recycling device for plastic mold processing, which has the following beneficial effects:

[0019] 1. The present invention crushes plastic waste by rotating a crushing roller, and when the crushing roller rotates, the screen frame can be driven to move up and down by the cooperation of a rotating rod and a driving rod, thereby achieving a screening effect, and after screening, the waste that fails the screening can be transferred to the rotating crushing roller for crushing again through a secondary processing conveying mechanism, thereby saving the time between the transfer from the crushing device to the crushing device, thereby saving time and labor, and improving the plastic recycling efficiency.

[0020] 2. The present invention collects and processes the dust generated during the pulverization by means of a cleaning mechanism, thereby preventing the dust from being dispersed during the pulverization, and can quickly discharge the dust through a dust scraping mechanism, which is convenient to use, thereby keeping the working environment clean and tidy, thereby preventing the staff from inhaling dust, and thus ensuring the health of the staff.
