[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1This embodiment of a continuous granulation device for processing EVA plastic particles includes a support plate 1, a plurality of legs 2 fixed below the support plate 1, a base plate 3 fixed on the side of the plurality of legs 2 away from the support plate 1, a feeding mechanism 4 for stable feeding is provided on the top of the support plate 1, a cutting and cooling assembly 5 for cutting the extruded material is provided on the right side of the feeding mechanism 4, a water supply assembly 6 fixedly connected to the cutting and cooling assembly 5 is provided below the base plate 3, and an electric fan 7 is provided between the support plate 1 and the base plate 3 for cooling the water supply assembly 6 and the water in the water supply assembly 6.

[0025] In addition, the feeding mechanism 4 includes a housing 401 fixed to the top of the support plate 1. A drive motor 402 located on the left side of the housing 401 is fixed to the top of the support plate 1. The drive motor 402 can provide a continuous and stable driving force to the rotating rod 403. One end of the output shaft of the drive motor 402 is fixed with a rotating rod 403 that passes through the housing 401. Two sealed bearings are fixed to the outer surface of the rotating rod 403. The rotating rod 403 is rotatably connected to the side wall of the housing 401 through the two sealed bearings. A heating layer 404 is provided on the inner side wall of the housing 401. An electric heating wire is provided in the heating layer 404. The heating layer 404 heats the EVA plastic through the electric heating wire. A feed nozzle 405 is fixedly connected to the top of the housing 401.

[0026] It should be further explained that a spiral blade is fixed on the outer surface of the rotating rod 403. The spiral blade, together with the rotating rod 403, can continuously and stably extrude the raw material. The outer side of the spiral blade is in contact with the heating layer 404.

[0027] In this embodiment, the right side of the outer shell 401 is provided with multiple extrusion holes, through which the raw material can be smoothly extruded, thereby facilitating the cutting and cooling assembly 5 to cut and cool the extruded molten raw material.

[0028] Please refer to it again. Figures 1 to 4 To facilitate the cutting of raw materials, the cutting and cooling assembly 5 in this embodiment includes a connecting frame 502. A driven rod 503 is fixed on the left side of the connecting frame 502 and extends into the feeding mechanism 4. Multiple cutting blades 504 are fixed on the left side of the connecting frame 502 and outside the driven rod 503. When the rotating rod 403 rotates, it will drive the connecting frame 502 to rotate together, which will cause the multiple cutting blades 504 to rotate. Due to the misalignment structure between the cutting blades 504 and the extrusion hole, the raw material can be effectively cut due to the shear force when it is extruded. Multiple blades 505 are fixed on the outside of the connecting frame 502. The blades 505 can cause the water to rotate. Multiple limiting parts 506 are provided on the inside of the connecting frame 502. A stabilizing plate 507 is abutted on the right side of the connecting frame 502. A waterproof shell 501 is placed on the top of the support plate 1.

[0029] Furthermore, multiple ear plates are provided on the outer sides of both the waterproof shell 501 and the outer shell 401. A bolt passes through each pair of mating ear plates, and a nut is threaded onto the outer surface of the bolt. Through the cooperation of the bolt, nut, and ear plate, the waterproof shell 501 can be smoothly fixed to the outer shell 401. A sealing ring is fixed on the left side of the waterproof shell 501, which can play a waterproof role. A stepped hole is opened on the right side of the rotating rod 403 and located outside the outer shell 401. Multiple keyways are opened on the inner side of the stepped hole. The driven rod 503 extends into the rotating rod 403 through the stepped hole. Multiple transmission keys are fixed on the outer surface of the driven rod 503, which respectively extend into the multiple keyways. Through the cooperation of the keyways and transmission keys, the power of the rotating rod 403 can be smoothly transmitted to the rotating rod 403.

[0030] It is known that each limiting part 506 includes a connecting rod 5061 fixed to the right side of the rotating rod 403. The inner left wall of the connecting rod 5061 is rotatably connected to a threaded rod 5062 extending out of the connecting rod 5061 via a bearing. The connecting rod 5061 is provided with a moving groove 5063 and a rotating groove 5065. The outer surface of the threaded rod 5062 is threadedly connected to a moving block 5064 extending into the moving groove 5063. When the threaded rod 5062 is rotated, the moving block 5064 will move, thereby causing the stabilizing plate 507 to abut against the connecting frame 502.

[0031] In addition, the water supply assembly 6 includes a water pump 601 fixed to the top of the base plate 3. A water tank 602 is fixedly connected to the left side of the water pump 601. An inlet pipe 603 and an outlet pipe 604 are fixedly connected to the right side of the water pump 601 and the left side of the water tank 602, respectively. The water pump 601 is used to provide power for the flow of water. A filter section 605 is provided at the end of the outlet pipe 604 away from the water tank 602. A drain pipe 606 is fixedly connected to the top of the filter section 605. Both the drain pipe 606 and the inlet pipe 603 are connected to the waterproof shell 501.

[0032] It should be further explained that the filter unit 605 includes a storage box 6051 that is fixedly connected to the water outlet pipe 604. The right side of the storage box 6051 is hinged to a movable door. A connecting plate 6052 is fixed to the inside of the storage box 6051. The connecting plate 6052 has multiple connecting holes to ensure that water can pass through smoothly. Multiple connecting springs 6053 are fixed to the top of the connecting plate 6052. A filter screen 6054 is fixed to the top of the multiple connecting springs 6053. When water flows down, the connecting springs 6053 will be compressed due to the impact force. When the external force disappears, the connecting springs 6053 will release elastic potential energy, causing the filter screen 6054 to shake up and down, thereby shaking off the water.

[0033] In this embodiment, when it is necessary to remove the connecting bracket 502, the threaded rod 5062 is rotated in the opposite direction, causing the moving block 5064 to move to the right. When the moving block 5064 moves into the rotating groove 5065, since one side is no longer limited, the moving block 5064 will rotate with the threaded rod 5062. At this time, the stabilizing plate 507 can be taken out, thereby removing the connecting bracket 502.

[0034] It is understandable that a connecting bearing is fixed inside the stepped hole, and the driven rod 503 abuts against the inner ring of the connecting bearing. This connection method can play a certain connecting role, and it can be removed simply by pulling out the driven rod 503 during disassembly.

[0035] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0036] The working principle of the above embodiments is as follows:

[0037] In use, the raw material is first put into the feed nozzle 405, and then the drive motor 402 is started. The drive motor 402 drives the rotating rod 403 to rotate, thereby causing the raw material to move stably inside the outer shell 401. At the same time, the heating layer 404 heats the raw material, causing it to become molten and be extruded from the right side of the outer shell 401. While being extruded, the cutting and cooling component 5 is constantly rotating, and the cutting blade 504 on it cuts the raw material into pellets. At the same time, the water supply component 6 causes water to continuously flow into the waterproof shell 501. Due to the stirring action of the paddle 505, the water will form a vortex and flow into the filter section 605. At this time, the pelleted plastic will remain in the filter section 605. The user only needs to take it out and then dry it.
