Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Referring to Figures 1 - 5 , a plastic particle feeding machine with a preheating function includes a base 1, and a feeding device is inclined above the base 1; wherein, as Figure 1 and Figure 3 shown, the feeding device includes a cylinder 2, a discharge port 11 is arranged below the top of the cylinder 2, and a feed port 13 is arranged above the bottom of the cylinder 2. A screw conveyor shaft 4 is arranged inside the cylinder 2, and the end of the screw conveyor shaft 4 is rotatably connected to the end of the cylinder 2. One end of the screw conveyor shaft 4 penetrates through the cylinder 2 and is connected to a first driving motor 5. The first driving motor 5 is fixed on the cylinder 2. The operation of the first driving motor 5 can drive the screw conveyor shaft 4 to rotate, thereby driving the plastic particles in the cylinder 2 to be conveyed upward.

[0029] On both sides of the bottom of the cylinder 2, support seats 6 are rotatably installed through rotating shafts. The support seats 6 are fixed on the base 1. Below the cylinder 2, an inclined telescopic mechanism 7 is provided. The top of the telescopic mechanism 7 is rotatably installed in the first U-shaped seat 8. The first U-shaped seat 8 is fixed on the cylinder 2. And the bottom of the telescopic mechanism 7 is rotatably installed in the second U-shaped seat 9. And the second U-shaped seat 9 is fixed on the support frame 10. And the support frame 10 is fixed on the base 1. In the actual use process, the telescopic mechanism 7 is one of an electric push rod, a cylinder, and a hydraulic cylinder, which can drive the cylinder 2 to rotate and adjust the inclination angle of the cylinder 2. When in use, the angle of the cylinder 2 can be adjusted according to the height of the plastic processing equipment, so as to facilitate the connection between the discharge port 11 and the plastic processing equipment.

[0030] It should be noted that, as Figure 1 shown, a first hose 12 is installed at the bottom of the discharge port 11, and the other end of the first hose 12 is installed with a connecting flange. When in use, the connecting flange is connected to the raw material inlet of the plastic processing equipment. And the flexible bending of the first hose 12 enables the installation and connection of the connecting flange to be unaffected regardless of the inclination of the cylinder 2 at various angles.

[0031] An aggregate hopper is installed at the upper end of the bottom of the conveying device. The aggregate hopper includes an aggregate box 15. The aggregate box 15 is connected to the base 1 through a fixing frame. The bottom of the aggregate box 15 is conical and is installed with a blanking pipe 27. The conical structure facilitates the plastic particles in the aggregate box 15 to fully fall downward; the blanking pipe 27 is connected to the feed inlet 13. In the actual use process, a second hose 14 is installed at the top of the feed inlet 13, and the other end of the second hose 14 is connected to the blanking pipe 27. Due to the vertical fixation of the aggregate box 15, the bending deformation of the second hose 14 does not hinder the angle adjustment of the cylinder 2;

[0032] A cover plate 16 is installed on the top of the aggregate box 15, and a material dropping port 17 is opened on one side of the cover plate 16. Plastic particles can be added to the aggregate box 15 from the material dropping port 17;

[0033] A connecting shaft 18 is arranged inside the aggregate box 15. The top of the connecting shaft 18 penetrates through the cover plate 16 and is installed with a driving mechanism for driving the connecting shaft 18 to rotate. The connecting shaft 18 is rotatably connected to the cover plate 16. The driving mechanism includes a first gear 21. The first gear 21 is placed above the cover plate 16 and is coaxially fixed with the connecting shaft 18. And a second gear 22 is meshed on the side of the first gear 21. A second driving motor 23 is installed on the second gear 22. The second driving motor 23 is fixed on the cover plate 16 through a bracket. Through the transmission of the gears, the second driving motor 23 provides power for the rotation of the connecting shaft 18.

[0034] On the side surface of the connecting shaft 18, a number of turnover plates 19 are arranged at intervals and inclined. The turnover plates 19 are connected to the connecting shaft 18 through a connecting frame 20. The turnover plates 19 are heat-conducting plates, and a number of cavities 29 are formed on the side surfaces of the turnover plates 19, and heating elements 30 are arranged in the cavities 29. After the plastic particles enter the aggregate bin 15, the turnover plates 19 will rotate with the connecting shaft 18, so as to turn and contact the plastic particles in the aggregate bin 15. During this process, the heating elements 30 will continuously generate heat, and transfer the heat to the plastic particles in contact with them through the turnover plates 19, so as to preheat the plastic particles before feeding, so that the plastic particles can be melted faster in the subsequent use process; and continuously rotating the turnover plates 19 also ensures that the heat is transferred to the plastic particles placed in the aggregate bin 15 comprehensively and sufficiently; in the actual use process, the heating element 30 is one of a heating rod and a heating wire.

[0035] Specifically, during use, first connect the connecting flange to the inlet of the plastic processing equipment, and then continuously pour the plastic particles into the aggregate bin 15. At this time, as the plastic particles flow into the cylinder 2, the plastic particles in the aggregate bin 15 will be preheated due to the heat transfer of the turnover plates 19. The plastic particles falling into the cylinder 2 will be conveyed towards the discharge port 11 under the rotation of the spiral conveyor shaft 4. The heat insulation plate 3 on the inner wall of the cylinder 2 can reduce the heat loss of the plastic particles during transportation in the cylinder 2. Finally, the plastic particles will fall into the plastic processing equipment from the discharge port 11 to complete the feeding operation of the plastic particles.

[0036] It should be noted that the connecting frame 20 and the connecting shaft 18 are both hollow. A slip ring is installed at the top of the connecting shaft 18. The slip ring includes a stator 24 and a rotor 25. The stator 24 is fixed on the top of the connecting shaft 18, and the wires of the heating element 30 are buried in the connecting frame 20 and the connecting shaft 18 and connected to the stator 24. The rotor 25 is rotatably installed on the stator 24, and the rotor 25 is fixed to the baffle 26 through a bracket. In the actual use process, the rotor 25 is connected with a power supply wire, and the power supply wire is connected to a power supply to supply power for the operation of the heating element 30. The setting of the slip ring ensures that when the heating element 30 is powered, the wires of the heating element 30 will not be damaged due to the rotation of the connecting shaft 18.

[0037] Furthermore, a baffle 26 is arranged in the middle of the cover plate 16. The baffle 26 corresponds to the first gear 21 and is arranged close to the feeding port 17, which can shield components such as gears and slip rings, so that when the plastic particles fall into the aggregate bin 15 from the feeding port 17, some particles will fall on the gears or slip rings, affecting their normal transmission or rotation.

[0038] It should be further noted that after the angle of the cylinder 2 is adjusted, the position of the discharge port 11 may have too large a deviation from the inlet position of the plastic processing equipment. If the connecting flange is directly fixed, it is very easy to cause excessive twisting of the first hose 12 and block the feeding of plastic particles. Therefore, self-locking universal wheels 28 are installed at the bottom corners of the base 1, which can be used to move and adjust the position of the feeding machine to ensure the smoothness of the first hose 12 after the adjustment of the cylinder 2; and it also facilitates the handling and movement of the feeding machine.

[0039] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
