[0001] The utility model relates to the technical field of conveying equipment, in particular to a plastic particle anti-blocking conveying equipment. Background Technique

[0002] Plastic particles, commonly known as plastic pellets, are raw materials for storing, transporting and processing plastic in semi-finished form. When plastic particles are processed as raw materials, they generally need to be conveyed to the equipment to be processed through a conveying device.

[0003] Existing conveying equipment generally conveys through a vacuum suction machine. However, during the conveying process, static electricity will be generated on the surface of plastic particles, which will cause the plastic particles to adsorb on the feeding hose or aggregate together, easily resulting in blockage. Moreover, the existing conveying equipment cannot adjust the height of the feeding hose, so when feeding equipment at different heights, different conveying pipes need to be replaced, and the use effect is poor. For this reason, we propose a plastic particle anti-blocking conveying equipment. Content of the Utility Model

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 - 4 , a plastic particle anti-blocking conveying device includes a base 1. A control box 28 is installed on the top of the base 1. A controller is installed in the control box 28. The controller is one of a control main board or a host. The top of the base 1 is provided with a material tank 11 through a plurality of support legs 4. A blanking pipe 3 is installed at the bottom of the material tank 11. The bottom end of the blanking pipe 3 is fixed on the conveying cylinder 2. The conveying cylinder 2 is fixed on the base 1. One end of the conveying cylinder 2 is connected to the exhaust end of the conveying pump 5, and the conveying pump 5 is fixed on the base 1. The other end of the conveying cylinder 2 is provided with a feeding hose 15. The conveying pump 5 is connected to the controller through a wire. During actual use, the conveying pump 5 can blow external air into the conveying cylinder 2 to blow the plastic particles falling from the material tank 11 into the feeding hose 15 for conveying.

[0029] It should be noted that, as Figure 1 shown, one end of the conveying cylinder 2 close to the feeding hose 15 is of a conical structure. In this way, when the air conveyed by the conveying pump 5 flows through the feeding hose 15, due to the reduction of the internal cross-section of the conveying cylinder 2, the air flow velocity will increase, preventing the plastic particles from being blocked.

[0030] AsFigure 3 As shown in the figure, a feed inlet 25 is provided on the side of the material tank 11. A spiral conveyor shaft 24 is rotatably connected inside the material tank 11. The bottom of the spiral conveyor shaft 24 extends into the blanking pipe 3, and the top of the spiral conveyor shaft 24 is connected to a first driving motor 10. The first driving motor 10 is fixed on the top of the material tank 11. The first driving motor 10 is connected to the controller through a wire. During actual use, the staff controls the first driving motor 10 to work through the controller. The first driving motor 10 drives the spiral conveyor shaft 24 to rotate, and conveys the plastic particles through the blanking pipe 3 to the conveying cylinder 2, and no blockage will occur during the conveying process.

[0031] It should be noted that the edge of the spiral conveyor shaft 24 is in clearance fit with the inner wall of the blanking pipe 3. In this way, during the conveying process, the plastic particles will not remain on the inner wall of the blanking pipe 3, and the spiral conveyor shaft 24 will not rub against the inner wall of the blanking pipe 3 during operation.

[0032] As Figure 1 and Figure 2 shown, on one side of the top of the material tank 11 near the feed inlet 25, a mounting seat 12 is installed. At least one mounting hole 8 is provided on the top of the mounting seat 12. The bottom end of the mounting hole 8 communicates with the inside of the material tank 11, and an ion blower 7 is installed inside the mounting hole 8. The ion blower 7 is connected to the controller through a wire. When adding plastic particles into the material tank 11, the staff can turn on the ion blower 7 through the controller. The ion blower 7 can blow the air containing ions towards the plastic particles falling into the material tank 11 from the feed inlet 25, removing the static electricity on the plastic particles, preventing the plastic particles from being adsorbed on the feeding hose 15 or adsorbed to each other and polymerized into a mass, so as to avoid blockage.

[0033] As Figure 1 shown, vertical plates 20 are symmetrically installed on the top of the base 1. Guide grooves 22 are provided on the adjacent surfaces of the two vertical plates 20. A support frame 18 is slidably connected inside each guide groove 22, and the top of each support frame 18 extends above the guide groove 22. The tops of the two support frames 18 are connected by a mounting plate 13. A rotating shaft 26 is rotatably connected to the top of the mounting plate 13. The bottom of the rotating shaft 26 is connected to a second driving motor 27. The second driving motor 27 is fixed to the bottom of the mounting plate 13. The second driving motor 27 is connected to the controller through a wire. The second driving motor 27 is a braking motor and can fix the rotating shaft 26 after adjusting the angle, and the rotating shaft 26 will not rotate by itself.

[0034] As Figure 1As shown, a support plate 14 is installed on the top of the rotating shaft 26, and a fixing seat 16 is vertically installed on the top of the supporting plate 14. One end of the feeding hose 15 is fixed on the fixing seat 16, and a discharge pipe 17 is installed on the other side of the fixing seat 16. The discharge pipe 17 is connected to the feeding hose 15. In actual use, the second driving motor 27 can drive the fixing seat 16 to rotate through the rotating shaft 26, and then the rotation angle of the discharge pipe 17 can be adjusted. The end of the discharge pipe 17 can be adjusted to a preset angle as needed.

[0035] It should be noted that the rotation angle of the rotating shaft 26 is A, 0°≤A≤360°, so that when the rotation angle of the discharge pipe 17 is adjusted, the feeding hose 15 will not be entangled on the fixing seat 16.

[0036] It should be noted that the bottom of the support plate 14 is in clearance with the top of the mounting plate 13, so that the fixing seat 16 can be supported by the support plate 14, so that the fixing seat 16 remains stable.

[0037] The bottoms of the two support frames 18 are connected by a strip connecting plate 21, and a telescopic mechanism 23 is installed at the bottom of the strip connecting plate 21. The bottom of the telescopic mechanism 23 is fixed on the base 1. The telescopic mechanism 23 is an electric push rod or a hydraulic cylinder, and the telescopic mechanism 23 is connected to the controller through a wire. In actual use, the strip connecting plate 21 can be pushed by the telescopic mechanism 23, and then the height of the discharge pipe 17 can be controlled, so as to facilitate the delivery of plastic particles to the preset equipment.

[0038] Specifically, when the utility model is in use, the staff first controls the telescopic mechanism 23 to work through the controller, and the telescopic mechanism 23 extends to push the strip connecting plate 21 upward, thereby driving the support frame 18 and the fixing seat 16 to move upward, so that the discharge pipe 17 can be adjusted to a preset height, and then the second drive motor 27 is controlled by the controller to work, and the second drive motor 27 drives the discharge pipe 17 to rotate through the rotating shaft 26, and adjusts the discharge pipe 17 to a preset angle, so that the end of the discharge pipe 17 is aligned with the silo of the external equipment, and then the staff transports the plastic particles into the material tank 11 through the feed port 25. At the same time, the staff controls the second drive motor 27 through the controller. The ion blower 7 and the first drive motor 10 are controlled to work. The ion blower 7 blows the air with ions to the plastic particles to remove the static electricity on the plastic particles. Then the first drive motor 10 drives the screw conveyor shaft 24 to rotate, and the plastic particles falling into the material tank 11 are conveyed to the conveying cylinder 2 through the drop pipe 3. At the same time, the controller controls the conveying pump 5 to work, and the conveying pump 5 blows external air into the conveying cylinder 2, so that the flowing air can blow the plastic particles falling into the conveying cylinder 2 into the feeding hose 15, and the plastic particles flow along the feeding hose 15 to the discharge pipe 17, and finally discharged to the external equipment silo through the discharge pipe 17 for subsequent processing.

[0039] Furthermore, as Figure 1 shown, a dust-proof net plate 9 is installed on the top of the mounting base 12. The dust-proof net plate 9 covers the top end of the mounting hole 8. The air inlet of the ion blower 7 can be blocked by the dust-proof net plate 9 to prevent dust or plastic particles from being sucked into the ion blower 7, so as to avoid damaging the ion blower 7.

[0040] Furthermore, as Figure 4 shown, a protective cover 19 is installed at the bottom of the mounting plate 13. The second driving motor 27 is located inside the protective cover 19. Under the action of the protective cover 19, the second driving motor 27 can be protected to prevent it from being damaged by an external object collision.

[0041] Furthermore, as Figure 1 shown, a guide plate 6 is installed on one side of the material tank 11 close to the feed inlet 25. The guide plate 6 is inclined, and the cross-section of the guide plate 6 is in a "U" shape structure. During actual use, the staff can pour the plastic particles on the guide plate 6. Under the action of gravity, the plastic particles will flow along the guide plate 6 to the feed inlet 25 and pass through the feed inlet 25 into the material tank 11.

[0042] The above is only a preferred specific embodiment 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 of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
