Description

Technical Field

[0001] The present invention relates to the field of plastic pellet production, and particularly to a feeding and conveying device for recycled plastic pellets. Background Art

[0002] Recycled plastic pellets, namely PCR plastic pellets, are plastic raw materials remade from used plastic products through steps such as collection, cleaning, and processing. During the plastic pellet processing, they generally go through stages such as heating, melting, and plasticization. Therefore, when they are extruded and conveyed to other devices, they still maintain a relatively high temperature.

[0003] The feeding and conveying device for recycled plastic pellets usually adopts an inclined conveyor belt design. Its working principle is to load materials from the lower end of the conveyor belt, and then use the continuous movement of the conveyor belt to convey the plastic pellets to a high place to provide raw materials for subsequent processing equipment. However, in the actual application process, since the plastic pellets may be soft and sticky due to incomplete cooling, these pellets often adhere to the outer surface of the conveyor belt, resulting in difficulty in completely separating the pellet materials during the conveying and feeding processes, thereby affecting the overall feeding efficiency and the smoothness of the production line.

[0004] Therefore, it is very necessary to propose a feeding and conveying device for recycled plastic pellets to solve the above problems. Summary of the Invention

On the outer periphery of the side of the side plate 1 facing the conveyor belt 3, a convex strip 8 with an inclination adapted to that of the conveyor belt 3 and located outside the edge of the conveyor belt 3 is provided. On the outer side of the upper end of the convex strip 8 inclined upward, second teeth 40 adapted to the first discharging gear 7 are evenly arranged, so that the first discharging gear 7 meshes with the second teeth 40 when passing through the second teeth 40;

[0045] As Figures 8-9 shown, in order to facilitate the reset of the discharging push plate 14 after discharging, a reset frame 29 is fixedly connected to the back side wall of the discharging push plate 14. A first T-shaped rod 33 corresponding to the reset frame 29 is fixedly connected to the inner wall of the storage cavity 10, and the reset frame 29 is movably sleeved on the outer side of the first T-shaped rod 33. A first spring 34 is sleeved on the outer part of one end of the first T-shaped rod 33 close to the discharging push plate 14, and is configured such that the first spring 34 is compressed when the discharging push plate 14 displaces in a direction away from the first T-shaped rod 33.

[0046] As Figures 8-9 shown, in order to increase the stability of the displacement of the discharging push plate 14 in the storage cavity 10, a cross arm 30 is fixedly provided at the end of the back surface of the discharging push plate 14. The cross arm 30 corresponds to the rack 27.

[0047] As Figure 2 and Figures 4-11As shown, as an embodiment, a drying mechanism is provided on the conveying box 4. The drying mechanism includes a wind gathering cavity 19 provided at one end of the conveying box 4 away from the storage cavity 10. A first rotating shaft 15 is rotatably connected in the wind gathering cavity 19 along the width direction of the conveyor belt 3. Both ends of the first rotating shaft 15 extend to the outside of the conveying box 4 and are fixedly provided with drying gears 6, and the drying gears 6 and the first discharging gear 7 are in different vertical planes. A first bevel gear 20 is uniformly provided on the outside of the first rotating shaft 15. One end of the wind gathering cavity 19 close to the storage cavity 10 is rotatably connected with a second rotating shaft 21 corresponding to the first bevel gear 20 one by one. A second bevel gear 24 meshing with the first bevel gear 20 is fixedly provided at one end of the second rotating shaft 21 close to the first bevel gear 20. A fan blade 23 is provided at one end of the second rotating shaft 21 close to the second bevel gear 24. A flow guiding cone 22 corresponding to the fan blade 23 is fixedly provided on the inner wall of the wind gathering cavity 19 at one end close to the storage cavity 10. In order to filter the incoming gas, a dust-proof net 13 is provided at one end of the wind gathering cavity 19 away from the storage cavity 10. Cavities 16 communicating with the wind gathering cavity 19 are provided at the top and both ends of the conveying box 4 close to one end of the storage cavity 10, and the cavities 16 are located outside the storage cavity 10. First air outlets 17 communicating with the cavities 16 are provided at the upper end and both ends inside the storage cavity 10. First teeth 9 are uniformly provided on the top of the convex strip 8 and the inclined upward end of the convex strip 8, and the first teeth 9 and the second teeth 40 are in different vertical planes.

[0048] In addition, as Figure 6 、 Figures 8-9 shown, in order to blow off the plastic particles on the discharging push plate 14 during discharging, second air outlets 18 are uniformly provided on the discharging push plate 14, and the first air outlets 17 are located at one end of the discharging push plate 14 away from the wind gathering cavity 19 in the initial state of the first spring 34. Therefore, the air flow will not blow out from the second air outlets 18 before discharging.

[0049] As Figure 4 、 Figures 6-9As shown, as an embodiment, a stirring assembly is provided on the discharging push plate 14. The stirring assembly includes a fixing frame 32 fixedly arranged on the side of the discharging push plate 14 close to the air gathering cavity 19. A fourth rotating shaft 35 is evenly and rotatably connected to the fixing frame 32. One end of the fourth rotating shaft 35 far from the air gathering cavity 19 extends to the side of the discharging push plate 14 far from the air gathering cavity 19, and a turning plate 12 is arranged on the end of the fourth rotating shaft 35 far from the air gathering cavity 19. A first cam 36 is fixedly arranged on the end of the fourth rotating shaft 35 close to the air gathering cavity 19. A connecting rod 37 is jointly and movably connected to a plurality of first cams 36. One end of the connecting rod 37 is provided with a traction frame 39. A guide rod 28 is rotatably connected to the end of the fixing frame 32 close to the traction frame 39. A second cam 38 for intermittently driving the displacement of the traction frame 39 is fixedly arranged at the corresponding position of the guide rod 28 and the traction frame 39. The guide rod 28 corresponds to one of the second rotating shafts 21, and one end of the guide rod 28 far from the fixing frame 32 is movably and guidingly connected to the inner side of the corresponding second rotating shaft 21, and the guide rod 28 and the second rotating shaft 21 are key-connected.

[0050] In addition, as Figure 1 , Figures 2-3 shown, a storage hopper 2 for storing plastic particles is fixedly arranged at the lower end of the side plate 1 and on the top of the lower end of the conveyor belt 3, and an opening is arranged at the bottom of the storage hopper 2. A plugging assembly for opening and closing the opening is arranged at the lower end of the storage hopper 2. The plugging assembly includes a sliding opening 45 arranged on one side of the lower end of the storage hopper 2. A plugging plate 41 is horizontally slidably connected to the sliding opening 45. A linkage member for driving the transverse displacement of the plugging plate 41 and linked with the displacement of the conveying box 4 is arranged on one side of the lower end of the storage hopper 2 close to the sliding opening 45. The linkage member includes a through groove 46 penetrating through the top of the outer end of the plugging plate 41. A driving plate 42 is vertically movably connected to the inner side of the through groove 46. A guide groove 47 is obliquely arranged on the end side wall of the inner cavity of the through groove 46. A guide wheel 48 movably connected to the guide groove 47 is arranged on the end side wall of the driving plate 42, and is configured such that when the driving plate 42 moves upward, the plugging plate 41 moves outward. A driving slope plate 5 for driving the driving plate 42 to rise is arranged on the top of the conveying box 4. In order to reduce the friction between the driving plate 42 and the driving slope plate 5, a roller 44 is rotatably connected to the lower end of the driving plate 42, and the roller 44 is used for rolling cooperation with the driving slope plate 5. When the roller 44 is in rolling cooperation with the driving slope plate 5, the plastic particles can fall between two adjacent conveying boxes 4, and then the plastic particles can enter the storage cavity 10 on a rear conveying box 4. And in order to facilitate the reset of the driving plate 42, an elastic assembly is arranged at the upper end of the driving plate 42. The elastic assembly includes a fixing plate 43 arranged on the side wall of the lower end of the storage hopper 2 and above the driving plate 42. A second T-shaped rod 49 is vertically movably connected to the fixing plate 43, and the bottom of the second T-shaped rod 49 is fixedly connected to the top of the driving plate 42. A second spring 50 is vertically arranged between the top of the driving plate 42 and the bottom of the fixing plate 43.

[0051] In order to facilitate the transfer box 4 to reach the end of the conveyor belt 3 for direction change and turning, a fixed base plate 11 is fixedly arranged at one end of the bottom of the transfer box 4, and the width of the fixed base plate 11 is smaller than the width of the transfer box 4. The fixed base plate 11 is fixedly connected to the outer side of the conveyor belt 3, and the bottom of the end of the transfer box 4 away from the fixed base plate 11 is attached to the outer side of the conveyor belt 3.

[0052] During use, the plastic particle raw materials are stored in the storage hopper 2. When the conveyor belt 3 operates, it will drive the conveying box 4 to operate synchronously. When the driving slope plate 5 at the top of the conveying box 4 contacts the roller 44, the roller 44 will be squeezed, and the roller 44 will drive the entire driving plate 42 to move upward. The second spring 50 is compressed, and then the guide wheel 48 drives the blocking plate 41 to move outward through the guide groove 47. Thus, the bottom opening of the storage hopper 2 is opened, and the plastic particles fall onto the conveyor belt 3 and then enter the storage cavity 10 on a conveying box 4 below. During the period when the conveying box 4 is located at the upper end of the conveyor belt 3, the drying gear 6 will engage with the first set of teeth 9, so that the first rotating shaft 15 rotates to drive the first bevel gear 20 to rotate. The first bevel gear 20 drives the second rotating shaft 21 to rotate through the second bevel gear 24. Then, the second bevel gear 24 rotates, and the air flow enters the air gathering cavity 19 and then enters the cavity 16 under the action of the diversion cone 22, and then blows into the inner side of the storage cavity 10 through the first air outlet 17. Thus, a certain degree of drying and cooling treatment can be performed on the plastic particles. Since initially the first air outlet 17 is located at the end of the unloading push plate 14 away from the air gathering cavity 19, the air flow will not blow out from the second air outlet 18, avoiding the plastic particles being blown out from the storage cavity 10. In addition, when the second rotating shaft 21 rotates, one of the second rotating shafts 21 will also drive the second cam 38 to rotate through the guide rod 28. The second cam 38 will intermittently contact the inner wall of the traction frame 39, and then intermittently realize the displacement of the entire traction frame 39 and the connecting rod 37. The reciprocating displacement of the connecting rod 37 drives the multiple fourth rotating shafts 35 to rotate reciprocally through the first cam 36. Then, the fourth rotating shafts 35 drive the turning plate 12 to rotate reciprocally, and the turning plate 12 turns the plastic particles, facilitating the drying and cooling treatment. When the conveying box 4 reaches the upper turning point of the conveyor belt 3, the first unloading gear 7 will engage with the second set of teeth 40, and then drive the second unloading gear 26 to rotate. The second unloading gear 26 drives the unloading push plate 14 to move outward through the rack 27. The connecting rod 37 is compressed by the cooperation of the reset frame 29 and the first T-shaped rod 33. The outward movement of the unloading push plate 14 can push out the plastic particles in the storage cavity 10. Moreover, since the guide rod 28 is movably and guidingly connected to one of the second rotating shafts 21, the guide rod 28 can also rotate during pushing. Due to the displacement of the unloading push plate 14, some of the first air outlets 17 will gradually be located at the end of the unloading push plate 14 close to the air gathering cavity 19. Thus, some of the air flow can be discharged through the second air outlet 18. Coupled with the turning of the turning plate 12, it is convenient to unload the plastic particles adhered to the unloading push plate 14 and the turning plate 12. And due to the action of the air flow blown out from the second air outlet 18, it is more convenient to discharge the plastic particles. When the conveying box 4 gradually moves to the bottom of the conveyor belt 3, the drying gear 6 will be separated from the first set of teeth 9, and the first unloading gear 7 will be separated from the second set of teeth 40. When it moves to the top of the conveyor belt 3 again, the drying gear 6 will engage with the first set of teeth 9 again, and this cycle continues.
