Gear 210 is fixed on the upper end of shaft 24 at a position corresponding to gear 29. Several stirring rods 25 are fixed on the main shaft 22, shaft 23, and shaft 24 inside the melting box 1.
[0025] Specifically, the stirring rods 25 on the main shaft 22, the first auxiliary shaft 23 and the second auxiliary shaft 24 are all staggered, and the main shaft 22, the first auxiliary shaft 23 and the second auxiliary shaft 24 are all rotatably connected to the melting box 1 through bearings.
[0026] By adopting the above technical solution, collisions between the stirring rods 25 on the main shaft 22, secondary shaft 1 23 and secondary shaft 24 are avoided, and the main shaft 22, secondary shaft 1 23 and secondary shaft 24 can all rotate in the melting box 1.
[0027] Specifically, the connecting belt 28 and the fixed frame 211, as well as the gear 29 and the fixed frame 211, are staggered, and the lower end of the interior of the melting box 1 is set as an inclined structure.

[0030] Example 2
[0031] The difference between this embodiment and embodiment 1 is that: a screen plate 8 is provided inside the feed pipe 5, and support plates 9 are provided at both ends inside the feed pipe 5. Protrusions 10 are fixed on both sides of the lower end of the screen plate 8, and grooves 11 corresponding to the protrusions 10 are provided on the upper end of the support plate 9.
[0032] By adopting the above technical solution, the sieve plate 8 is placed in the feed pipe 5, the support plate 9 supports the sieve plate 8, and the protrusions 10 on both sides of the lower end of the sieve plate 8 enter the groove 11 at the upper end of the support plate 9. When feeding material into the feed pipe 5, the sieve plate 8 can screen the masterbatch entering the melting box 1 and can screen out impurities mixed in the masterbatch.
[0033] Specifically, a push rod 12 is slidably connected to the lower end of the feed pipe 5 at the position corresponding to the screen plate 8. A push plate 14 is fixed to the upper end of the push rod 12, and a handle 13 is fixed to the lower end of the push rod 12.
[0034] By adopting the above technical solution, when cleaning the screen plate 8, the push rod 12 is pushed upward by the gripping rod 13. The push rod 12 pushes the push plate 14 upward in the feed pipe 5. The push plate 14 can push the screen plate 8 upward. By setting the push rod 12 and the push plate 14, it is easy to remove the screen plate 8 from the feed pipe 5 for cleaning, and avoid the screen plate 8 being tightly attached to the inner wall of the feed pipe 5 after installation, which makes it inconvenient to remove.
[0035] Specifically, a cover plate 15 is hinged to the upper end of the feed pipe 5, and a handle 16 is fixed to one end of the cover plate 15. A rubber pad is glued to the surface of the handle 16.
[0036] By adopting the above technical solution, when no material needs to be added, the cover plate 15 can be rotated to the upper end of the feed pipe 5 by rotating the handle 16, which can seal and protect the upper end of the feed pipe 5 and prevent external impurities from falling into the melting box 1 through the feed pipe 5.
[0037] In this embodiment, by setting a sieve plate 8, the sieve plate 8 is placed in the feed pipe 5. The support plate 9 supports the sieve plate 8. The protrusions 10 on both sides of the lower end of the sieve plate 8 enter the grooves 11 on the upper end of the support plate 9. When feeding material into the feed pipe 5, the sieve plate 8 can screen the masterbatch entering the melting box 1 and remove impurities mixed in with the masterbatch. When it is necessary to clean the sieve plate 8, the push rod 12 is pushed upward by the handle 13. The push rod 12 pushes the push plate 14 upward in the feed pipe 5. The push plate 14 can push the sieve plate 8 upward. By setting the push rod 12 and the push plate 14, it is easy to remove the sieve plate 8 from the feed pipe 5 for cleaning. This avoids the sieve plate 8 being tightly attached to the inner wall of the feed pipe 5 after installation, making it difficult to remove. When it is not necessary to feed material, the cover plate 15 is rotated to the upper end of the feed pipe 5 by the handle 16. This can seal and protect the upper end of the feed pipe 5 and prevent external impurities from falling into the melting box 1 through the feed pipe 5.
[0038] In this utility model, the motor 21 is a previously disclosed technology, and the selected model is 5IK120GN-CF.
[0039] In this utility model, the electric heating element 6 is a previously disclosed technology, and the selected model is BLT-DRB.
[0040] The working principle and usage process of this utility model: When using the PP plastic masterbatch mixing and melting device, the device is installed in a suitable position. With the stirring assembly 2 in place, the masterbatch to be mixed is added to the melting tank 1 through the feed pipe 5. The electric heating element 6 is then turned on to heat-melt the masterbatch in the melting tank 1. The motor 21 is turned on to drive the main shaft 22 to rotate clockwise. The main shaft 22 drives the auxiliary shaft 23 to rotate clockwise via pulley 26, pulley 27, and connecting belt 28. The main shaft 22 drives the auxiliary shaft 24 to rotate counterclockwise via gears 29 and 210. The rotation of the main shaft 22, auxiliary shaft 23, and auxiliary shaft 24, through several stirring rods 25, mixes and stirs the masterbatch in the melting tank 1. By setting the stirring assembly 2, the masterbatch in the melting tank 1 can be stirred and mixed in multiple directions, improving the mixing quality of the masterbatch. A sieve plate 8 is also included. The sieve plate 8 is placed in the feed pipe 5, and the support plate 9 supports the sieve plate 8. The protrusions 10 on both sides of the lower end of the sieve plate 8 enter the grooves 11 on the upper end of the support plate 9. When feeding material into the feed pipe 5, the sieve plate 8 can screen the masterbatch entering the melting box 1 and remove impurities mixed in with the masterbatch. When the sieve plate 8 needs to be cleaned, the push rod 12 is pushed upward by the handle 13. The push rod 12 pushes the push plate 14 upward in the feed pipe 5. The push plate 14 can push the sieve plate 8 upward. By setting the push rod 12 and the push plate 14, it is easy to remove the sieve plate 8 from the feed pipe 5 for cleaning. This avoids the sieve plate 8 being tightly attached to the inner wall of the feed pipe 5 after installation, making it difficult to remove. When feeding is not required, the cover plate 15 is rotated to the upper end of the feed pipe 5 by the handle 16. This can seal and protect the upper end of the feed pipe 5 and prevent external impurities from falling into the melting box 1 through the feed pipe 5.
