Then the screening machine body 1 can be placed at the position corresponding to the discharge port of the granulator, and then the plastic particles can be cooled by the water inside the screening machine body 1. During the cooling of the plastic particles, the plastic particles can be filtered and screened through the screening net 5. At the same time, the driving motor can be used to drive the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the stirring rod 7 to rotate, thereby stirring the plastic particles. It can effectively prevent the plastic particles from clogging the screening net 5, so that the cooling and screening effect of the plastic particles is better. After the screening is completed, the lifting plate 3 can be driven to rise by the electric push rod, and the collecting trough 4 can be taken out, so that the plastic particles can be taken out. At the same time, the screened plastic particles will enter the interior of the collecting bucket 8, and then the sealing plug 10 can be removed to allow water to flow out through the water outlet.

After the water has finished flowing out, the plastic particles inside the collecting bucket 8 can be taken out, making the recovery of the screened plastic particles more convenient.
[0025] like Figure 3 to Figure 4 As shown, the rotating shaft 6 is divided into two sections, and the bottom end of the rotating shaft 6 located at the top is fixedly connected to a threaded sleeve 11, and the top of the rotating shaft 6 located at the bottom is fixedly connected to a threaded block 12; the threaded block 12 is threadedly connected at an internal position of the threaded sleeve 11; during operation, when the rotating shaft 6 and the stirring rod 7 need to be cleaned or replaced, the threaded block 12 can be screwed out of the threaded sleeve 11, thereby making the replacement and cleaning of the rotating shaft 6 and the stirring rod 7 more convenient.
[0026] like Figure 1 to Figure 2As shown, a plurality of guide blocks 13 are fixedly connected to the side wall of the collecting trough 4; a guide groove is provided on the inner side wall of the screening machine body 1; the guide blocks 13 are arranged corresponding to the guide groove; when working, by arranging the guide blocks 13 on the side wall of the collecting trough 4 and restricting the guide blocks 13 by the guide groove, the stirring rod 7 can effectively avoid the collection trough 4 from rotating when stirring the water, so that the collection trough 4 has a better filtering effect on plastic particles.
[0027] like Figure 3 to Figure 4 As shown, the inside of the threaded sleeve 11 is slidably connected with a sliding block 14; a spring is fixedly connected between the top of the sliding block 14 and the inner wall of the threaded sleeve 11; during operation, when the threaded block 12 is screwed into the inside of the threaded sleeve 11, the sliding block 14 is pushed by the spring, which can make the pressure between the threaded block 12 and the threaded hole greater, making the friction between the threaded block 12 and the threaded hole greater, thereby making the friction between the threaded block 12 and the threaded hole greater.

[0029] like Figure 5 As shown, a plurality of anti-wear balls 16 are arranged between the lifting plate 3 and the positioning block 15; the side walls of the anti-wear balls 16 are in contact with the side walls of the lifting plate 3 and the positioning block 15; during operation, when the positioning block 15 rotates inside the lifting plate 3, by arranging the anti-wear balls 16 between the lifting plate 3 and the positioning block 15, the sliding friction between the lifting plate 3 and the positioning block 15 can be converted into rolling friction, so that the friction force between the lifting plate 3 and the positioning block 15 is smaller, thereby reducing the wear between the lifting plate 3 and the positioning block 15.
[0030] During operation, in the process of producing plastic particles, cooling water can be first injected into the interior of the screening machine body 1. The liquid level of the cooling water needs to be higher than the height of the screening net 5. Then the screening machine body 1 can be placed at a position corresponding to the discharge port of the granulator. Then, the plastic particles can be cooled by the water inside the screening machine body 1. During the cooling process of the plastic particles, the plastic particles can be filtered and screened through the screening net 5. At the same time, the driving motor can be used to drive the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the stirring rod 7 to rotate, thereby stirring the plastic particles, which can effectively The plastic particles are prevented from clogging the screening net 5, so that the cooling and screening effect of the plastic particles is better. After the screening is completed, the lifting plate 3 can be driven to rise by the electric push rod, and the collecting tank 4 can be taken out, so that the plastic particles can be taken out.

[0032] By providing a guide block 13 on the side wall of the collecting tank 4 and limiting the guide block 13 through the guide groove, the stirring rod 7 can effectively prevent the collecting tank 4 from rotating when stirring the water, so that the collecting tank 4 has a better filtering effect on plastic particles.
[0033] When the threaded block 12 is screwed into the threaded sleeve 11, the sliding block 14 is pushed by the spring, which can increase the pressure between the threaded block 12 and the threaded hole, thereby increasing the friction between the threaded block 12 and the threaded hole.
[0034] When the rotating shaft 6 rotates inside the lifting plate 3 , the lifting plate 3 limits the rotation of the positioning block 15 , so that the rotating shaft 6 is less likely to tilt during rotation, and the rotation of the rotating shaft 6 is more stable.
[0035] When the positioning block 15 rotates inside the lifting plate 3, by arranging the anti-wear ball 16 between the lifting plate 3 and the positioning block 15, the sliding friction between the lifting plate 3 and the positioning block 15 can be changed into rolling friction, so that the friction force between the lifting plate 3 and the positioning block 15 is smaller, thereby reducing the wear between the lifting plate 3 and the positioning block 15.
