[0002] Waste plastic recycling refers to the process of recycling, sorting, cleaning, crushing and other preliminary processing of discarded plastics in daily life or industrial production, and recycling them. These waste plastics mainly come from various plastic packaging, plastic bags, plastic bottles, plastic tableware, plastic films, etc., and also include scraps or waste products in industrial production.

[0003] Recycled waste plastics can be converted into renewable plastic granules through a series of processing in a granulator. The working principle of the granulator mainly includes feeding, hot melt extrusion, cooling, water filtration, air drying, cutting and discharging. The material is first evenly transported to the hot melt extrusion chamber through the feeding device, and is compressed into strips under the joint action of the spiral and the mold, and then cooled, filtered and air dried, and then cut by a rotating cutting knife, and finally the cut particles are discharged through the discharge port.

[0004] However, during the use of the existing waste plastic recycling particle processing granulator, the three processing steps of cooling, filtering, and air drying are connected to each other, resulting in a longer overall length of the production line, which occupies more processing site and space, and is not conducive to full utilization of the site. Therefore, the existing granulator cannot meet people's usage needs during use. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 As shown, the utility model is a waste plastic recycling particle processing granulator, comprising: a drying component 1, a cooling component 2, an extruder 3 and a cutter 4, the extruder 3 is fixedly connected to one end of the cooling component 2, the cutter 4 is fixedly connected to the other end of the cooling component 2, and the drying component 1 is fixedly installed on the side of the cooling component 2;

[0027] The drying component 1 includes a support frame 12, a water filter plate 13, a plug-in frame 19 and a limiting sleeve 17. The water filter plate 13 is fixedly mounted on the upper outer surface of the support frame 12. The limiting sleeve 17 is symmetrically arranged at the inner center of the support frame 12. The plug-in frame 19 is slidably plugged into the top of the limiting sleeve 17. The top of the support frame 12 and directly above the water filter plate 13 is evenly rotated and clamped with an air-drying shaft 110. The top of the plug-in frame 19 is fixedly connected with an air-drying hood 16.

[0028] An air dryer 15 is arranged at the top center of the air drying hood 16, a driving motor 11 is arranged inside the support frame 12 and between the limiting sleeves 17, a threaded rod 18 is fixedly connected to the top of the driving motor 11, the bottom of the plug-in frame 19 is threadedly connected to the outer surface of the threaded rod 18, and limiting rollers 14 are evenly arranged inside the upper surface of the water filter plate 13.

[0029] The cooling component 2 includes a cooling roller shaft 21 , a material shifting rack 22 and a cooling water tank 23 . The cooling roller shaft 21 is evenly arranged on one side of the interior of the cooling water tank 23 , and the material shifting rack 22 is clamped on one end of the interior of the cooling water tank 23 .

[0030] The water filter plate 13 in the utility model is located directly above the cooling water tank 23, and the overall size of the cooling water tank 23 is larger than the overall size of the water filter plate 13, which can prevent water droplets inside the water filter plate 13 from falling to the outside of the cooling water tank 23, thereby being able to receive all water droplets dripping from the water filter plate 13.

[0031] The outer surface of the material shifting rack 22 in the utility model is provided with a groove, which can facilitate the material shifting rack 22 to be connected with the extruded plastic strip through the groove, so as to facilitate the staff to control the movement of the pulled extruded plastic strip. Only one end of the two ends of the cooling roller shaft 21 is in contact with the inner surface of the cooling water tank 23, and a gap can be reserved on one side of the inner side of the cooling water tank 23 to facilitate the cooling water tank 23 to slide inside the material shifting rack 22. The support frame 12 is fixedly connected to the outer surface of the cooling water tank 23 to ensure the stability of the support frame 12. A limit block is set at one end of the air-drying shaft 110 to prevent the sliding plastic strip from detaching from the outer surface of the air-drying shaft 110.

[0032] The working principle of the utility model is as follows: before processing the recycled waste plastics into plastic particles, first adjust the height of the air-drying hood 16, control the driving motor 11 to drive the threaded rod 18 to rotate, so that the end of the plug-in frame 19 rises on the outer surface of the threaded rod 18, and at the same time the plug-in frame 19 will drive the air-drying hood 16 away from the upper surface of the air-drying shaft 110, and then place the waste plastics into the extruder 3 to heat and melt, and extrude the melted plastic from one end, and at the same time the staff picks up the material shifting frame 22 so that the groove at one end is aligned with the extrusion end of the extruder 3, and when the extruded plastic strip falls into the groove, quickly rotate the material shifting frame 22 to bend the plastic strip, and pull the plastic strip to the other end under the cooling roller 21 inside the cooling water tank 23, and then pull it upward to the outer surface of the limit roller 14, and pull it to the other end, and then continue to pull the plastic strip upward, and It is set up on the outer surface of the air-drying shaft 110 and finally pulled to the other end, and then the driving motor 11 is controlled to drive the threaded rod 18 to rotate in the opposite direction, thereby driving the air-drying hood 16 to descend to the top of the air-drying shaft 110 through the plug-in frame 19, and at the same time, the air-drying machine 15 blows air downward to dry and dissipate the plastic strips sliding on the upper surface of the air-drying shaft 110, and then the end is inserted into the side of the cutting machine 4. The cutting machine 4 will cut the plastic strips when it is running, and finally form plastic particles. When the plastic strips pass through the upper surface of the water filter plate 13, the water on the plastic surface will fall into the inside of the water filter plate 13, starting the water filtering effect, and the filtered water will pass through the water filter plate 13 and drip into the cooling water tank 23 for collection. Therefore, by stacking the water filter plate 13, the air-drying shaft 110 and the air-drying hood 16 up and down, the footprint of the granulator can be reduced in the horizontal space, thereby meeting people's usage needs.

[0033] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
