Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling, in particular to a waste plastic recycling device. Background Art

[0002] The plastic bottle recycling process includes collection, sorting, cleaning, crushing, compression and final processing. In this process, the compression step is located after crushing, and its purpose is to further compress the crushed plastic bottles to reduce their volume for easy storage and transportation.

[0003] China Utility Model Announcement No.: CN220638589U includes a compression component and a diversion component. The crushed plastic first contacts the diversion baffle during the falling process. The diversion baffle divides the bottom falling space into several identical areas, which can divert the crushed plastic. Then, the crushed plastic in the central area of ​​the feed port is guided by the guide plates and bending parts inclined on both sides, changing its movement convenience so that it is spread to the areas on both sides below the feed port, thereby ensuring that the crushed plastic can be evenly spread inside the device, effectively avoiding the crushed plastic from accumulating directly below the feed port during unloading, forming a material pile similar to a cone, ensuring continuous feeding of the device, and improving the working efficiency of the device. The inclination of the guide plate and the bending part can also be changed by rotating the adjusting lever to control the guide angle, which is more convenient and quick, and meets the changing work requirements in actual work.

[0004] The applicant found that this patent had some shortcomings in use: the device did not have the function of secondary compression, and only compressed the plastic once, making the plastic not small enough and not tight enough.

[0005] Therefore, the present invention designs a waste plastic recycling device to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of the utility model is to provide a waste plastic recycling device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waste plastic recycling device, comprising: a recycling box, a main hydraulic cylinder is installed on one side of the recycling box, the output end of the main hydraulic cylinder is connected to the main pressure plate, both ends of the recycling box away from the main hydraulic cylinder are provided with side grooves, and auxiliary pressure plates are inserted in the side grooves, an auxiliary hydraulic cylinder is installed on the recycling box, the output end of the auxiliary hydraulic cylinder is connected to the auxiliary pressure plate, a discharge trough is provided on the other side of the recycling box, a discharge plate is provided in the discharge trough, a rotating shaft is rotatably installed under the discharge trough, and a rotating block fixedly installed to the bottom of the discharge plate is installed on the outer wall of the rotating shaft.

The output end of the multi-stage electric push rod is connected to the bottom of the extension plate, and the extension plate is slidably connected to the slot. When blanking, the multi-stage electric push rod drives the extension plate to extend, and then the rotating shaft drives the rotating block to rotate to rotate the blanking plate, so that the extension plate contacts the ground and is in an inclined state. The compressed plastic can automatically move downward to the ground. At this time, there is still a part of the plastic block on the extension plate. The multi-stage electric push rod drives the extension plate to retract into the slot, and the plastic block can all fall to the ground, completing the blanking. Then the blanking plate returns to its original position, and the compression operation can continue. The entire blanking process of the plastic block does not require staff to carry it to the ground, which is more labor-saving.

[0009] Preferably, an electric cylinder is installed on the top of the recycling box, and the output end of the electric cylinder is connected to a plug block. One end of the extension plate is provided with a limiting groove for plugging with the plug block. During the first compression, the electric cylinder drives the plug block to be inserted into the extension plate, which can limit the blanking plate and improve the stability of the blanking plate.

[0010] Preferably, a machine slot is provided at the bottom of the recycling box, and a servo motor is installed in the machine slot. One end of the rotating shaft passes through the machine slot and is connected to the output end of the servo motor. The servo motor drives the rotating shaft to rotate forward and reverse, so that the blanking plate can be rotated forward and reverse to open and close.

[0011] Preferably, support legs are provided at the four corners of the bottom of the recycling box, and the support legs support the recycling box.

[0012] Preferably, a controller is provided at one end of the recycling box, and the controller is convenient for staff to operate.

The plastic is compressed to the auxiliary pressure plate, and the auxiliary hydraulic cylinder drives the auxiliary pressure plate to extend to perform the second compression on the plastic. Through the secondary compression, the plastic is made smaller and more compact, which is more convenient to transport and store. BRIEF DESCRIPTION OF THE DRAWINGS
