TECHNICAL FIELD
[0001] The utility model relates to a plastic stay device. BACKGROUND
[0002] The plastic granulator is mainly used for processing waste plastic film (industrial packaging film, agricultural mulch, greenhouse film, handbag, etc.), woven bag, agricultural convenient bag, basin, bucket, beverage bottle, furniture, daily necessities lamp, and is suitable for most common waste plastics, is the most widely used and the most popular plastic regeneration processing machinery in the waste plastic regeneration industry, such as the "continuous silk screen changer for plastic granulation production" disclosed in Chinese patent CN202321749344.3, which is a device that pre-mixes and plasticizes plastic raw materials to form a plastic melt, and extrudes the plastic melt into a plastic strip. The plastic strip is cut into plastic particles of a certain length by the plastic granulator after cooling.
[0003] The above-mentioned screen changer, the plastic raw material enters the shell 1 through a group of feeding ports, then enters the first square tube through the round pipe, passes through the round connecting piece into the filter plate, is filtered through the filter plate, and then flows out from the first discharge port. When the filter screen needs to be replaced, the lifting device lifts the filter plate that needs to be replaced through the hydraulic telescopic rod, one round pipe at the feeding port is closed, the plastic raw material passes through the other round pipe and the filter plate, and then is sent into the round connecting piece connected thereto and the second square tube. The short-range hydraulic telescopic rod is started, the adapter pipe moves, the round pipe connected to the first square tube is separated from the main adapter pipe and is locked by the outer wall of the adapter pipe, the auxiliary adapter pipe is connected to the round pipe connected to the second square tube, the second discharge hole is connected to the pipeline below, the plastic raw material enters the auxiliary adapter pipe through the second square tube and the round pipe, then enters the discharge box, and finally is transported to other equipment through the second discharge hole. After the filter screen replacement is completed, the lifting device returns the filter screen plate to the original position, the short-range hydraulic telescopic rod pushes the adapter pipe back, and the plastic raw material resumes the initial travel route and is output from the first discharge hole, achieving continuous flow.
[0004] This design flows the plastic raw material into the shell through a group of feeding ports, then divides the flow by two groups of round pipes, selects one group of round pipes for the plastic raw material to enter, filters the plastic raw material through the filter screen, and then discharges the plastic raw material through the corresponding discharge hole. At the same time, two groups of discharge holes are additionally provided to block the discharge hole that does not discharge by the short-range hydraulic telescopic pipe, which is an unreasonable design with a complex structure.
[0005] In order to avoid the occurrence of the flow interruption phenomenon, the device needs to fill the plastic raw material in another conveying channel in advance. When the filter screen is replaced and the plastic raw material is conveyed by the other group of round pipes, the continuous flow effect can be achieved. The operation process is very complicated.

While the plastic raw material is continuously discharged by the discharging assembly, the first material feeding hole is continuously fed. The user controls the feeding speed to be greater than the discharging speed, and at this time, the plastic raw material generates hydraulic pressure, which causes a part of the plastic raw material to pass through the second discharging hole and enter the second channel, continuously fill the second channel, and form a vacuum state until the second channel is filled with the second channel. As time passes, impurities in the plastic raw material are continuously filtered by the first filter, and the impurities in the plastic raw material are continuously attached to the first filter, so that the first filter is blocked, and the user needs to replace the first filter. When the plastic raw material is discharged by the first channel and the filling of the second channel is completed, the user controls the hydraulic cylinder to drive the material distribution slider to slide and block the first material feeding hole, the plastic raw material is injected from the second material feeding hole, filtered by the second filter, then enters the discharging assembly through the second discharging hole, and is then discharged by the discharging assembly.
