Description

Technical Field

[0001] The utility model relates to the technical field of plastic pellet production, in particular to a plastic pellet packaging device with improved efficiency. Background Art

[0002] Plastic pellets are the common name for plastic particles. They are the raw materials for storing, transporting and processing plastics in the form of semi-finished products. Plastics are a type of polymer material. Petroleum can be used as a raw material to produce ethylene, propylene, vinyl chloride, styrene, etc. The molecules of these substances can react with each other under certain conditions to form compounds with large molecular weight, namely polymers.

[0003] After the production of plastic pellets is completed, the plastic pellets need to be bagged and packaged. However, when the existing plastic pellet packaging device is in use, the feed pipe at the bottom of the storage tank needs to be adapted to the packaging bag, and the radius of the storage tank itself is much larger than the radius of the feed pipe. This will cause the plastic pellets at the bottom of the storage tank to be squeezed and accumulated by the plastic pellets above it. In addition, the plastic pellets themselves are small in size and can easily interact with each other under pressure, thereby clogging the feed pipe and reducing the packaging efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 , a plastic pellet packaging device with improved efficiency, comprising a conveying device, and a feeding device arranged above the conveying device, wherein the feeding device is fixed to the conveying device through a support frame 2;

[0024] The unloading device includes a unloading tank 1, which is located above the conveying device and is fixed to the support frame 2 through a fixed seat 3, wherein the unloading tank 1 includes a tank body 11 with an opening on the top, and a top cover 12 installed on the top of the tank body 11 through a flange, and the fixed seat 3 is fixed on the outer wall of the tank body 11 to facilitate disassembly of the unloading tank 1 and cleaning of the inside of the unloading tank 1.

In actual use, the packaging bag and the opening of the discharge nozzle 4 are placed in the same direction to ensure stability when the plastic pellets are discharged. A feeding pipe is installed on one side of the top of the discharge tank 1 to facilitate the addition of materials into the discharge tank 1.

[0026] like Figure 3 and Figure 4As shown, a first drive motor 5 is installed on the top of the discharge tank 1 (that is, the first drive motor 5 is installed on the top of the top cover 12), a drive shaft 6 is installed on the bottom of the first drive motor 5, the drive shaft 6 penetrates into the interior of the discharge tank 1 and the two are rotatably connected (that is, the drive shaft 6 is rotatably connected to the top cover 12), the bottom of the drive shaft 6 is rotatably installed on the connecting frame 10, the connecting frame 10 is fixed to the bottom of the discharge tank 1 (that is, the connecting frame 10 is fixed to the bottom of the tank body 11), a second spiral blade 9 is coaxially installed at the bottom of the drive shaft 6, and a plurality of first spiral blades 7 are coaxially arranged at intervals on the side of the drive shaft 6, and the plurality of first spiral blades 7 are arranged along the same spiral The first spiral blade 7 is set in the "L"-shaped connecting rod 8, the top of the connecting rod 8 is fixed on the driving shaft 6, and the connecting rod 8 is matched with the inner wall clearance of the discharge tank 1 (that is, the inner wall clearance of the connecting rod 8 and the tank body 11 is matched). When packaging, the rotation of the first spiral blade 7 will transfer the plastic pellets at the edge of the discharge tank 1 upward, thereby loosening the plastic pellets at the bottom of the discharge tank 1 and reducing the interaction between the plastic pellets, making it easier for the second spiral blade 9 to drive the plastic pellets to rotate in a spiral manner, so that the second spiral blade 9 can quickly transport the plastic pellets to the discharge nozzle 4 for discharging, thereby improving the packaging efficiency of the plastic pellets.

[0027] Further, such as Figure 1 As shown, the conveying device includes two parallel supporting beams 13, and a driving roller 14 is provided at the end between the two supporting beams 13. The end of the driving roller 14 is rotatably connected to the supporting beam 13. A second driving motor 16 is installed at one end of one of the driving rollers 14, and the second driving motor 16 is fixed on the supporting beam 13. A conveyor belt 15 is arranged on the driving roller 14, and the supporting beam 13 is installed on the base 18 through a plurality of spaced-apart pillars, wherein the supporting frame 2 is installed on the base 18, and the packaging bag is placed on the conveyor belt 15.

The telescopic mechanism 20 is installed on a fixed frame 21, one of the fixed frames 21 is fixed on the support frame 2, and the other fixed frame 21 is fixed on the base 18. When packing, the limit seats 19 will move to both sides of the packing bag under the action of the telescopic mechanism 20, thereby limiting the side of the packing bag to prevent the center of gravity of the packing bag from shifting and tipping over during packing.

[0030] It should be further explained that, in order to ensure the stability of the limit seat 19 when it moves, a guide shaft 22 is provided parallel to the side of the telescopic mechanism 20, one end of the guide shaft 22 is fixed on the limit seat 19, and the other end of the guide shaft 22 slides through the fixing frame 21.
