Description

Technical Field

[0001] This utility model relates to the technical field of plastic pellet production equipment, and in particular to a plastic pellet lifting device. Background Technology

[0002] In the plastics processing industry, the conveying and lifting of plastic granules is a crucial step in the production process. Lifting devices are typically used to transport plastic granules from lower to higher locations (such as silos) to meet subsequent processing needs. Currently, most common plastic granule lifting devices employ a structure of a lifting pipe combined with a conveying screw. The rotation of the conveying screw pushes the plastic granules upwards along the lifting pipe, and they ultimately fall to the target location through the discharge pipe at the upper end of the lifting pipe.

[0003] However, existing plastic pellet lifting devices have significant technical flaws. The fixed position of the discharge pipe means the plastic pellets can only fall from a fixed location, eventually accumulating in the same spot within the collection container. When the collection container has a large volume, this fixed discharge method causes localized accumulation of plastic pellets, making it difficult to evenly distribute them and fill the container completely. To fill the container, it often requires constant manual adjustment of the container's position or handling and leveling of the accumulated plastic pellets. This not only increases the labor intensity of workers and wastes labor costs but also interrupts production continuity and reduces production efficiency. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a plastic particle lifting device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A plastic granule lifting device includes a lifting pipe with a conveying screw rotatably mounted inside it. A discharge pipe is provided on the lower side of the upper end of the lifting pipe. Fixed seats are provided on both sides of the discharge pipe, and rotating columns are rotatably mounted on the two fixed seats. Connecting rods are detachably mounted on the rotating columns. Semi-arc guide plates are connected to the lower ends of the two connecting rods. The semi-arc guide plates are located below the discharge pipe and are used to guide the plastic granules falling from the discharge pipe. A driving device for driving the rotating columns to rotate is also provided on the lifting pipe.

[0007] In some embodiments, the driving device includes a gear disposed on the rotating column, a rack that can mesh with the gear sliding on the fixed seat, a cylinder disposed on the lifting tube, and a connecting frame disposed on the piston rod of the cylinder, the connecting frame being connected to the rack.

[0008] In some embodiments, a slot is provided on the side wall of the rotating column, one end of the connecting rod is inserted into the slot and locked by bolts.

[0009] In some embodiments, the device further includes a movable support, on which a hinge seat is provided, at the lower end of the lifting tube a mounting seat, on which a hinge shaft is provided, the hinge shaft being rotatably mounted on the hinge seat, and on which a swing adjustment device is provided for driving the lifting tube to swing up and down around the hinge shaft as an axis is also provided.

[0010] In some embodiments, the swing adjustment device includes a linear screw module disposed on the movable support, a support rod disposed on the movable slider of the linear screw module, a transverse guide column disposed on the support rod, and a slide rail extending along the length direction disposed on the lower side of the lifting tube, the transverse guide column being slidably disposed within the slide rail.

[0011] In some embodiments, movable wheels are provided at the four corners of the bottom wall of the movable support.

[0012] In some embodiments, a feed hopper is provided on the upper side of the lower end of the riser tube.

[0013] In some embodiments, a motor for driving the conveying screw to rotate is provided on the lower end face of the lifting tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By incorporating a semi-circular guide plate, a rotating column, and a drive device, the drive device rotates the rotating column, which in turn rotates the semi-circular guide plate. The semi-circular guide plate, at different angles, guides the plastic granules falling from the discharge pipe in different directions, allowing for flexible adjustment of the discharge position. This ensures that the plastic granules are evenly distributed within the collection container, preventing localized accumulation and making it easier to fill the container without requiring manual adjustment of the container position or leveling of the granules.

[0016] 2. Since no manual intervention is required to adjust the stacking state of the plastic granules, manual operation is reduced, the labor intensity of workers is lowered, and labor costs are saved. At the same time, the production process can be carried out continuously, avoiding production interruptions caused by manual operation and effectively improving production efficiency.

[0022] like Figures 1-4 The illustrated plastic granule lifting device includes a lifting pipe 1, a conveying screw 2 rotatably installed inside the lifting pipe 1, a discharge pipe 3 provided on the lower side of the upper end of the lifting pipe 1, fixed seats 4 provided on both the left and right sides of the discharge pipe 3, rotating columns 5 rotatably installed on the two fixed seats 4, connecting rods 6 detachably installed on the rotating columns 5, and semi-arc guide plates 7 connected to the lower ends of the two connecting rods 6. The semi-arc guide plates 7 are located below the discharge pipe 3 and are used to guide the plastic granules falling from the discharge pipe 3. A driving device for driving the rotating columns 5 to rotate is also provided on the lifting pipe 1.

[0023] Based on the above structure, by setting up a semi-circular guide plate 7, a rotating column 5, a driving device, etc., the driving device can drive the rotating column 5 to rotate, thereby driving the semi-circular guide plate 7 to rotate. The semi-circular guide plate 7 can guide the plastic particles falling from the discharge pipe 3 in different directions at different angle positions, realizing flexible adjustment of the discharge position. In this way, the plastic particles can be evenly distributed in the collection container, avoiding local accumulation, thus making it easier to fill the entire container without manually adjusting the container position or spreading the particles.

[0024] Since no manual intervention is required to adjust the stacking state of the plastic granules, manual operation is reduced, the labor intensity of workers is lowered, and labor costs are saved. At the same time, the production process can be carried out continuously, avoiding production interruptions caused by manual operation and effectively improving production efficiency.

[0025] See Figure 1 As shown, the front side of the semi-circular guide plate 7 is inclined downward, so that the plastic particles can be guided to the front of the discharge pipe 3.

[0026] See Figure 2As shown, the rear side of the semi-circular guide plate 7 is inclined downward, so that the plastic particles can be guided to the rear of the discharge pipe 3.

[0027] In this invention, the driving device includes a gear 21 mounted on the rotating column 5, a rack 22 that can mesh with the gear 21 sliding on the fixed seat 4, a cylinder 23 mounted on the lifting tube 1, and a connecting frame 24 mounted on the piston rod of the cylinder 23, the connecting frame 24 being connected to the rack 22.

[0028] When the piston rod of cylinder 23 extends or retracts, it drives rack 22 to slide, thereby driving gear 21 and rotating column 5 to rotate. Finally, the guiding direction of semi-arc guide plate 7 is adjusted through connecting rod 6.

[0029] See Figure 4 As shown, a slot 31 is provided on the side wall of the rotating column 5. One end of the connecting rod 6 is inserted into the slot 31 and locked by bolts 32.

It is easy to replace, repair or clean the semi-arc guide plate 7. At the same time, different specifications of guide plates can be replaced according to different discharge requirements, which improves the flexibility and versatility of the device.
