[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown in this embodiment, a raw material screening device for processing disposable plastic cups includes a housing 1. A screening mechanism is installed inside the housing 1, a vibration mechanism is installed at the bottom of the housing 1, and a cooling mechanism is provided on one side of the housing 1. The screening mechanism includes a first guide plate 9, which is fixedly connected to the top of the housing 1. A feeding hopper 3 communicates with the top of the housing 1. A first screening plate 10 is fixedly connected to the top of the housing 1, and a second screening plate 10 is fixedly connected to the middle of the housing 1. The guide plate 11, the second screen plate 12 is fixedly connected to the middle of the box body 1, and the third guide plate 13 is fixedly connected to the bottom of the box body 1. The first guide plate 9, the first screen plate 10, the second guide plate 11, the second screen plate 12 and the third guide plate 13 are arranged in order from top to bottom inside the box body 1. The first guide plate 9 and the second guide plate 11 are used to guide the plastic particles so that the plastic particles can pass through the mesh on the first screen plate 10 and the second screen plate 12 throughout the process.

[0023] Plastic granules are poured into the housing 1 through the feed hopper 3. After the vibration mechanism operates, the plastic granules are guided by the first guide plate 9 to fall onto the first screen plate 10. The plastic granules screened by the first screen plate 10 fall onto the second guide plate 11, and are then guided by the second guide plate 11 to the second screen plate 12 for further screening. Finally, the plastic granules screened by the second screen plate 12 fall onto the third guide plate 13 to achieve the purpose of grading and screening.

[0024] A first through groove 14 is provided on the top of one side of the box body 1, a second through groove 15 is provided in the middle of one side of the box body 1, and a third through groove 16 is provided on the bottom of one side of the box body 1. The top surface of one end of the first screening plate 10, the second screening plate 12 and the third guide plate 13 coincides with the inner bottom surface of the first through groove 14, the second through groove 15 and the third through groove 16, respectively.

[0025] The cooling mechanism includes a fan 5, which is fixedly connected to the top of one end of the base plate 4. The output end of the fan 5 is connected to a diversion pipe 6, and the outside of the diversion pipe 6 is connected to three air outlet pipes 7. One end of each of the three air outlet pipes 7 is connected to an air diffuser 8.

[0026] The air diffusers 8 are respectively set above the sides of the first screen plate 10, the second screen plate 12 and the third guide plate 13. The interior of the air diffuser 8 located inside the housing 1 is fixedly connected with a grid. The grid can prevent plastic particles from entering the air diffuser 8. During the screening of plastic particles, since the freshly produced plastic particles still have residual heat, the fan 5 can be started to cool them down. The fan 5 draws air from the outside, which is then distributed to each air outlet pipe 7 by the diversion pipe 6, and then dispersed and blown out by the air diffusers 8 to cool down the plastic particles on the first screen plate 10, the second screen plate 12 and the third guide plate 13.

[0027] like Figure 1 and Figure 3 As shown, a discharge hopper 2 is fixedly installed at one end of the first channel 14, the second channel 15, and the third channel 16. A discharge hole 17 is opened at one end of the discharge hopper 2. A guide pipe is installed in the discharge hole 17. The guide pipe is used to discharge the graded and screened plastic particles into the storage container. The inner bottom surface of the discharge hopper 2 is inclined to the discharge hole 17. Under the action of the vibration mechanism, the plastic particles guided by the first screen plate 10, the second screen plate 12, and the third guide plate 13 will enter the corresponding discharge hopper 2 through the first channel 14, the second channel 15, and the third channel 16 respectively, and be discharged through the discharge hole 17 and the connected guide pipe.

[0028] like Figure 1 and Figure 4 As shown, the vibration mechanism includes a base plate 4, and a number of columns 18 are fixedly connected to the top of one end of the base plate 4. Springs 19 are fixedly connected to the outer side of the top of each of the columns 18, and one end of the springs 19 is fixedly connected to the bottom of the housing 1.

[0029] A connecting frame 20 is fixedly connected to the middle of the bottom of the box 1. A vibration motor 21 is fixedly connected inside the connecting frame 20. When the vibration motor 21 is started, the box 1 begins to vibrate under the support of the spring 19 so that the plastic particles can be screened and graded by the first screen plate 10 and the second screen plate 12.

[0030] This utility model provides a raw material screening device for processing disposable plastic cups. The specific working principle is as follows: Plastic granules are poured into the box 1 through the feeding hopper 3, and the vibration motor 21 is started. The box 1 begins to vibrate under the support of the spring 19. Then, the plastic granules are guided by the first guide plate 9 to fall onto the first screening plate 10. The plastic granules screened by the first screening plate 10 fall onto the second guide plate 11 and are guided by the second guide plate 11 to the second screening plate 12 for screening. Finally, the plastic granules screened by the second screening plate 12 fall onto the third guide plate 13. At this time, the plastic granules on the first screening plate 10, the second screening plate 12 and the third guide plate 13 enter the corresponding discharge hopper 2 through the first through groove 14, the second through groove 15 and the third through groove 16, and are finally discharged through the discharge hole 17 and the connected guide pipe.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
