Description

Technical Field

[0001] This utility model relates to the field of polypropylene granule packaging technology, and in particular to an automatic bagging and packaging machine for polypropylene granules. Background Technology

[0002] Polypropylene granules are one of the most basic and important raw materials in the plastics industry. After the polypropylene granules are produced, they need to be bagged and packaged using automatic bagging and packaging machines.

[0003] For example, CN113277132B discloses a plastic granule packaging bag device with an automatic opening and fixing function. This device provides an automatic opening and sealing packaging bag for plastic granules. The device includes a base plate, an opening mechanism, and a feeding mechanism. The opening mechanism is mounted on the top of the base plate, and the feeding mechanism is located on the top side of the base plate near the opening mechanism. When the opening mechanism operates, it conveys the rightmost bag in the feeding mechanism forward to directly below the dropping mechanism, eliminating the need for separate bag placement and reducing labor intensity. When the opening mechanism operates, it opens the bag's inlet, simultaneously positioning the inlet over the outlet of the dropping mechanism. The dropping mechanism then allows the plastic granules to fall into the bag, completing the bagging process. However, since plastic granules usually generate dust during the packaging process, and the plastic granule bagging device cannot remove the dust generated during the bagging process, the accumulation of dust can easily cause an explosion and pollute the surrounding environment.

[0004] Therefore, an automatic bagging and packaging machine for polypropylene granules has been developed that can remove the dust generated during the bagging process, thus avoiding pollution of the working environment and reducing safety hazards. Utility Model Content

[0005] To overcome the shortcomings of existing plastic granule bagging devices, which cannot remove the dust generated during the granule bagging process, and whose dust accumulation can easily cause explosions and pollute the surrounding environment, this utility model provides an automatic polypropylene granule bagging and packaging machine that can remove the dust generated during the polypropylene granule bagging process, avoid polluting the working environment, and reduce safety hazards.

[0006] The technical solution is as follows: An automatic bagging and packaging machine for polypropylene granules includes a conveyor, partitions, protrusions, first gears, clamping plates, first racks, sliding frames, elastic elements, pulleys, a bagging assembly, a bag feeding assembly, and a sealing assembly. Multiple partitions are connected to the conveyor belt. A protrusion is connected to the front side of the conveyor's middle section. A first gear is rotatably connected to the middle of each partition. Clamping plates are slidably connected to both the front and rear parts of each partition. A first rack is connected to each clamping plate, and each first rack meshes with an adjacent first gear. A sliding frame is connected to each clamping plate on the front side, and each sliding frame is slidably connected to an adjacent partition. An elastic element connects each sliding frame to the connected partition. A pulley is rotatably connected to the inner front part of each sliding frame. The sliding frame is press-fitted with the protrusion through the pulley. The conveyor is equipped with a bagging assembly capable of filling polypropylene granules into packaging bags. The bagging assembly is equipped with a bag feeding assembly capable of lifting the packaging bags upwards. The conveyor is also equipped with a sealing assembly capable of sealing the packaging bags.

[0007] As an improvement to the above solution, multiple pads are provided on the underside of the conveyor.

[0008] As an improvement to the above solution, the elastic element is a telescopic spring.

[0009] As an improvement to the above solution, the bagging assembly includes a support frame, a first electric push rod, a feeding frame, and a dust suction pipe. The support frame is connected to the middle of the conveyor, and the first electric push rod is connected to the upper sides of both the front and rear parts of the support frame. The feeding frame is connected between the telescopic ends of the first electric push rod, and the dust suction pipe is connected to both the left and right sides of the feeding frame.

[0010] As an improvement to the above solution, the bag feeding assembly includes a second rack, a second gear, a third rack, a second electric push rod, and an electric suction cup. The second rack is connected to both the front and rear sides of the feeding frame. The second gear is rotatably connected to both the front and rear sides of the upper part of the support frame. The third rack is slidably connected to the lower part of the second rack. Both the third rack and the second rack mesh with the adjacent second gear. The lower part of the third rack is connected to the second electric push rod. The electric suction cup is connected to the telescopic end of the second electric push rod.

[0011] As an improvement to the above solution, the sealing assembly includes a third electric push rod and a hot melt plate. Multiple third electric push rods are connected to the upper right side of the conveyor, and a hot melt plate is connected between the telescopic ends of two adjacent third electric push rods.

[0012] As an improvement to the above solution, the conveyor, the first electric push rod, the second electric push rod, the electric suction cup, the third electric push rod, the hot melt plate, and the processor are electrically connected through a control module.

[0013] This utility model has the following advantages: When polypropylene granules are poured into the packaging bag from the feeding frame, a vacuum cleaner is connected to the external suction pipe. When the polypropylene granules are bagged, the vacuum cleaner is started and the dust generated during the bagging process is sucked out through the suction pipe, which can avoid polluting the working environment and reduce safety hazards.

[0021] An automatic bagging and packaging machine for polypropylene granules, such as Figures 1-5As shown, the assembly includes a conveyor 1, partitions 2, protrusions 3, a first gear 4, clamping plates 5, a first rack 6, a sliding frame 7, elastic elements, pulleys 9, a bagging assembly, a bag feeding assembly, and a sealing assembly. Twelve partitions 2 are connected to the conveyor belt of the conveyor 1. Four pads are provided on the underside of the conveyor 1 to prevent wear on the ground. A protrusion 3 is connected to the front of the middle section of the conveyor 1. The middle of each partition 2 is rotatably connected to a first gear 4. Clamping plates 5 are slidably connected to both the front and rear sections of each partition 2. Each clamping plate 5 is connected to a first gear 6. A rack 6 is provided, and the first rack 6 meshes with the adjacent first gear 4. A sliding frame 7 is connected to the front clamping plate 5. The sliding frame 7 is slidably connected to the adjacent partition plate 2. An elastic element, which is a telescopic spring 8, is connected between the sliding frame 7 and the connected partition plate 2. A pulley 9 is rotatably connected to the inner front part of the sliding frame 7. The sliding frame 7 is pressed and engaged with the protrusion 3 through the pulley 9. A bagging assembly is provided on the conveyor 1. A bag feeding assembly is provided on the bagging assembly. A sealing assembly is also provided on the conveyor 1.

[0022] like Figure 1 , Figure 4 and Figure 5 As shown, the bagging assembly includes a support frame 10, a first electric push rod 11, a feeding frame 12, and a dust suction pipe 18. The support frame 10 is connected to the middle of the conveyor 1. The first electric push rod 11 is connected to the upper sides of both the front and rear parts of the support frame 10. The feeding frame 12 is connected between the telescopic ends of the first electric push rod 11. The feeding frame 12 is slidably connected to the support frame 10. The dust suction pipe 18 is connected to both the left and right sides of the feeding frame 12.

[0023] like Figure 1 and Figure 4 As shown, the bag feeding assembly includes a second rack 13, a second gear 14, a third rack 15, a second electric push rod 16, and an electric suction cup 17. The front and rear sides of the feeding frame 12 are connected to the second rack 13. The front and rear sides of the upper part of the support frame 10 are rotatably connected to the second gear 14. The lower part of the second rack 13 is slidably connected to the third rack 15. The third rack 15 and the second rack 13 are both meshed with the adjacent second gear 14. The lower part of the third rack 15 is connected to the second electric push rod 16. The telescopic end of the second electric push rod 16 is connected to the electric suction cup 17.

[0024] like Figure 1 and Figure 2 As shown, the sealing assembly includes a third electric push rod 19 and a hot melt plate 20. Four third electric push rods 19 are connected to the upper right side of the conveyor 1. A hot melt plate 20 is connected between the telescopic ends of two adjacent third electric push rods 19. The conveyor 1, the first electric push rod 11, the second electric push rod 16, the electric suction cup 17, the third electric push rod 19, the hot melt plate 20 and the processor are electrically connected through a control module.

[0025] When using this utility model, first place the conveyor 1 in the polypropylene granule packaging area, then place the packaging bag between the clamping plates 5. Through the force of the telescopic spring 8, the clamping plates 5 clamp the packaging bag. The processor starts the conveyor 1 through the control module to transport the packaging bag to the right. When the packaging bag is transported to the bottom of the unloading frame 12, the pulley 9 contacts the protrusion 3, causing the sliding frame 7 to move forward. The telescopic spring 8 is squeezed and contracted. While the sliding frame 7 moves forward, it drives the front clamping plate 5 to move forward. Through the meshing motion of the first rack 6 and the first gear 4, the rear clamping plate 5 moves backward, releasing the packaging bag. The processor activates the second electric push rod 16 and the electric suction cup 17 through the control module, pushing the electric suction cup 17 closer together to adsorb the packaging bag, and then moving the electric suction cup 17 away from each other to open the packaging bag. Then, the first electric push rod 11 is activated to push the feeding frame 12 downward, which drives the second rack 13 downward, so that the second gear 14 and the third rack 15 mesh and move, thereby causing the second electric push rod 16 and the electric suction cup 17 to move upward, covering the packaging bag outside the feeding frame 12 to prevent polypropylene granules from falling out. Then, the polypropylene granules are poured from the feeding frame 12 into the packaging bag. After bagging is completed, the electric suction cup 17 stops adhering to the packaging bag and continues to transport the packaging bag to the right. At this time, the pulley 9 disengages from the protrusion 3, the telescopic spring 8 rebounds, and the sliding frame 7 resets. This causes the clamping plates 5 to move closer together and clamp the packaging bag again. When the packaging bag moves between the hot melt plates 20, the processor starts the third electric push rod 19 and the hot melt plates 20 through the control module, so that the hot melt plates 20 move closer together and are heated to seal the packaging bag, thus completing the bagging and packaging of polypropylene granules. This cycle is repeated to achieve continuous bagging and packaging of polypropylene granules. When pouring polypropylene granules from the feeding frame 12 into the packaging bag, a vacuum cleaner can be connected to the suction pipe 18. When the polypropylene granules are being bagged, the vacuum cleaner can be turned on and the dust generated during the bagging process can be sucked out through the suction pipe 18, thereby avoiding pollution of the working environment and reducing safety hazards.
