Based on the embodiments in 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.

[0030] See also Figure 1-6The utility model provides a technical solution: a resin screening device with a vertical multi-stage screening structure, including a shell 1, a feed port 2, a motor 3, a rotating shaft 4, a filter plate 5, a moving frame 6, a fixed plate 7, a connecting pipe 8, a tooth chain 9, a support plate 10, a material box 11, a connecting plate 12, a cylinder 13, a push plate 14, and a material box 2 15. Embodiment 1

[0031] The resin screening device is provided with a multi-stage screening structure, which enables the resin particles to be screened multiple times through the filter plate 5, specifically:

[0032] The side surface of the shell 1 is correspondingly provided with openings, and also includes a feed port 2, which is installed through the upper surface of the shell 1. The shell 1 is provided with a multi-stage screening structure inside, and the multi-stage screening structure can screen the resin three times in sequence by controlling the rotation of the filter plate 5. The multi-stage screening structure includes a motor 3, which is installed on the front surface of the shell 1. The motor 3 is fixedly connected with a rotating shaft 4, and the two ends of the rotating shaft 4 are respectively rotatably installed on the front and rear surfaces of the inner wall of the shell 1. The outer surface of the rotating shaft 4 is fixedly installed with a filter plate 5, and the upper surface of the filter plate 5 is symmetrically fixed with a fixed plate 7, and a movable frame 6 is slidably installed between the fixed plates 7. The movable frame 6 A connecting pipe 8 is fixedly installed on the upper surface of the filter plate 5, and the upper end of the connecting pipe 8 is fixedly installed on the upper surface of the inner wall of the shell 1. Another connecting pipe 8 is connected to the lower surface of the filter plate 5, and the lower end of the connecting pipe 8 is connected to the fixing plate 7 on the upper surface of the second filter plate 5. A connecting pipe 8 is also provided between the lower surface of the second filter plate 5 and the fixing plate 7 on the upper surface of the third filter plate 5. A sprocket is fixedly installed on the outer surface of the rotating shaft 4 to which the three filter plates 5 are fixedly connected, and a tooth chain 9 is meshed and connected on the outer surface of the sprocket.

Figure 3As shown, the resin particles will fall onto the upper surface of the filter plate 5 through the connecting pipe 8 between the first filter plate 5 and the upper surface of the inner wall of the shell 1, and will be located between the moving frames 6. A fixed plate 7 is fixedly installed on the upper surface of the filter plate 5, and the moving frame 6 is slidably installed between the fixed plates 7. The sliding friction between the moving frame 6 and the fixed plates 7 is relatively large, so there will be no natural sliding. Then the motor 3 is turned on, and the motor 3 will drive the rotating shaft 4 to rotate. The outer surface of the rotating shaft 4 is fixedly connected to the filter plate 5, and the motor 3 is set to rotate alternately in forward and reverse directions, so the filter plate 5 will swing and rotate around the rotating shaft 4 as the center.

At the same time, since the tooth chain 9 is connected to the rotating shaft 4 fixedly connected to the three filter plates 5, the three filter plates 5 swing and rotate at the same time, so that the resin particles are screened through the three vertically arranged filter plates 5 in turn, so that the resin particles are divided into four grades of different sizes. Embodiment 2

[0034] The resin screening device is provided with a graded discharging structure, so that the resin particles of different sizes after screening enter different material boxes 11 respectively, specifically:

[0035] The housing 1 is also connected with a graded discharging structure, which can push the moving frame 6 through the push plate 14 so that the material above the filter plate 5 enters the material box 11.

A connecting plate 12 is fixedly mounted on the other side surface of the housing 1, and a cylinder 13 is fixedly mounted on the side surface of the connecting plate 12, and a piston rod of the cylinder 13 slides through the side surface of the connecting plate 12 and is fixedly connected with a push plate 14, and the front end of the push plate 14 is set to an iron material, and the front end of the push plate 14 corresponds to the opening of the side surface of the housing 1 respectively, and a material box 15 is slidably mounted on the bottom surface of the housing 1, and the front surface of the housing 1 is provided with an opening corresponding to the material box 15, the moving frame 6 on the upper surface of the filter plate 5 corresponds to the opening of the side surface of the housing 1, and the side surface of the moving frame 6 is provided with a magnet corresponding to the push plate 14;

[0036] After the resin particles are screened, the smallest resin particles will pass through the third filter plate 5 and fall into the second material box 15. The second material box 15 is slidably mounted on the bottom surface of the housing 1. The second material box 15 can be pulled out through the handle on the front surface of the second material box 15. Resin particles of different particle sizes will be left on the upper surface of the three filter plates 5. At this time, the motor 3 drives the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the filter plates 5 to adjust to a parallel state, such as Figure 2 As shown, the two sides of the filter plate 5 correspond to the openings on the two side surfaces of the shell 1 respectively, and then the side surface of the connecting plate 12 is fixedly installed with a cylinder 13, which is opened and will push the push plate 14 to move. The side end of the push plate 14 corresponds to the opening on the side surface of the shell 1, and the push plate 14 will push the moving frame 6 to move the moving frame 6 to the right. The moving frame 6 will drive the resin particles on the upper end of the filter plate 5 to move, and then the moving frame 6 passes through the opening on the side surface of the shell 1, so that the resin particles fall into the material box 11, and the material box 11 is placed on the support plate 10 fixedly installed on the side surface of the shell 1, so that three resin particles of different sizes fall into different material boxes 11 respectively, which is convenient for the staff to classify and take, and then the cylinder 13 drives the push plate 14 to move to the left, so that the iron material at the front end of the push plate 14 pulls the moving frame 6 back through the magnet set on the side surface of the moving frame 6, which is convenient for the next use.
