[0026] The injection molding raw material enters the filter box 3 and falls on the oblique filter plate 4. The oblique filter plate 4 is inclined. The weight of the raw material is relatively large. Under the influence of gravity acceleration, the raw material moves to the downward inclined end of the oblique filter plate 4. When the raw material moves to the end of the oblique filter plate 4, it moves obliquely upward along the oblique guide plate 6, and falls on the guide plate 25 through the gap between the oblique filter plate 4 and the filter box 3. The raw material is filtered on the oblique filter plate 4. Dust and other impurities in the raw material pass through the oblique filter plate 4 and fall on the oblique impurity discharge plate 5. The dust and other impurities are discharged from the filter box 3 through the oblique impurity discharge plate 5. The raw material moves along the guide plate 25. The raw materials fall onto the oblique screening plate 7, which screens the raw materials. Raw materials of qualified size pass through the oblique screening plate 7 and fall into the feed hopper 1. Large raw materials cannot pass through the oblique screening plate 7. Large raw materials move along the oblique screening plate 7. Large raw materials enter the grinder 8 through the feed pipe 9, and are crushed by the grinder 8. The crushed raw materials fall into the feed hopper 1 through the discharge pipe 10, which can filter the raw materials to prevent dust and other impurities from melting together with the raw materials, to prevent dust and impurities from affecting product quality, to make the raw materials the same size, to prevent uneven melting of the raw materials, and to improve product quality.

[0027] Refer to the instruction manual Figure 1 And the instruction manual Figure 2 A vertical impurity discharge pipe 11 is installed on one side of the filter box 3. A discharge port 12 is provided at the connection between the vertical impurity discharge pipe 11 and the filter box 3. One end of the oblique impurity discharge plate 5 penetrates the discharge port 12 and extends into the vertical impurity discharge pipe 11.

[0028] An impurity collecting box is placed below the vertical impurity discharge pipe 11, and impurities discharged by the oblique impurity discharge plate 5 enter the vertical impurity discharge pipe 11 through the impurity discharge port 12. The impurities are discharged into the impurity collecting box through the vertical impurity discharge pipe 11, which facilitates the collection of impurities and avoids mixing of impurities with raw materials.

[0029] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 And the instruction manual Figure 4 A transverse through groove 13 is provided on the top of the filter box 3, a linear slide 14 is installed on the top of the filter box 3, a power push rod 15 is installed on the sliding block of the linear slide 14, a fixed sleeve 16 is installed on the telescopic end of the power push rod 15, a connecting slide rod 17 is slidably connected in the fixed sleeve 16, a telescopic spring 18 is provided in the fixed sleeve 16, a brush 19 is provided at one end of the connecting slide rod 17, and the brush 19 contacts the surface of the oblique filter plate 4,

[0030] After long-term use, impurities are easily stuck in the filter holes of the oblique filter plate 4, and the power push rod 15 starts to work. The telescopic end of the power push rod 15 extends to drive the fixed sleeve 16, the connecting slide rod 17 and the brush 19 to move downward. The brush 19 contacts the surface of the oblique filter plate 4, and the linear slide 14 starts to work. The fixed sleeve 16, the connecting slide rod 17 and the brush 19 are driven to slide horizontally through the linear slide 14. When the brush 19 moves in the upward inclined direction of the oblique filter plate 4, the connecting slide rod 17 applies pressure to the telescopic spring 18. The telescopic spring 18 is deformed and contracted due to the pressure, and the connecting slide rod 17 slides along the fixed sleeve 16. The brush 19 can move upward, and the oblique filter plate 4 can be cleaned to remove impurities on the surface of the oblique filter plate 4, thereby preventing impurities from clogging the filter holes of the oblique filter plate 4 and improving the filtering effect.

[0031] Refer to the instruction manual Figure 3 The oblique screening plate 7 includes a fixed frame 20 and a plurality of screening rods 21. The plurality of screening rods 21 are evenly fixed in the fixed frame 20, and the spacing between adjacent screening rods 21 is the same.

[0032] Ordinary screening plates use filter holes for screening, which can easily get the raw materials stuck and unable to move. Using multiple screening rods 21 for screening can avoid getting the raw materials stuck and unable to move, and the raw materials can move along the spacing between adjacent screening rods 21.

[0033] Refer to the instruction manual Figure 1And the instruction manual Figure 2 One side of the filter box 3 is connected to an L-shaped feeding pipe 22, the other end of the L-shaped feeding pipe 22 is connected to a flexible feeding pipe 23, and the L-shaped feeding pipe 22 is connected to a negative pressure fan 24.
