Description

Technical Field

[0001] This utility model relates to the field of plastic pellet packaging technology, specifically a moisture-proof and recyclable plastic pellet packaging device. Background Technology

[0002] Recycled plastic pellets are granular materials made from recycled and reprocessed used plastic waste. They help reduce dependence on limited natural resources and reduce the environmental burden by recycling waste plastics. Recycled plastic pellets promote the development of a circular economy and achieve efficient use of resources. In addition, the production of recycled plastic pellets consumes less energy than the production of new plastics, which helps to slow down the consumption of energy resources. After processing, recycled plastic pellets need to be packaged for storage, transportation and sale.

[0003] Currently, recycled plastic pellets are usually packaged in boxes or bags, which have poor sealing properties and are easily affected by moisture, reducing the quality of the recycled plastic pellets and making them unsuitable for later processing and use. To address this, we propose a moisture-proof packaging device for recycled plastic pellets. Utility Model Content

[0004] The purpose of this utility model is to provide a moisture-proof packaging device for recycled plastic granules, which facilitates vacuum packaging of recycled plastic granules to improve sealing, prevent the recycled plastic granules from getting damp, ensure the quality of the recycled plastic granules and their subsequent use. It solves the problem that the current packaging of recycled plastic granules in boxes or bags has poor sealing, is prone to getting damp, reduces the quality of the recycled plastic granules, and is not conducive to subsequent processing and use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof and recyclable plastic pellet packaging device, comprising a base, a placement cylinder, and a sealing plate. A fixing frame is fixedly installed on the upper surface of the placement cylinder, and a first hydraulic cylinder and a vacuum pump are fixedly installed on the upper surface of the fixing frame. The output end of the first hydraulic cylinder is fixedly connected to the sealing plate. Cylinders are symmetrically fixedly installed on both sides of the outer surface of the placement cylinder near the upper surface, and hollow plates are fixedly connected to the output ends of both cylinders. Adsorption holes are provided on the inner sides of both hollow plates, and ultrasonic sealing plates are fixedly installed on the inner sides of both hollow plates below the adsorption holes.

[0006] Preferably, a three-way valve is fixedly connected to the input end of the vacuum pump, and a three-way pipe is fixedly connected to the end of the three-way valve. The remaining two ends of the three-way pipe are respectively fixedly connected to a first branch pipe and a second branch pipe. A connecting pipe is fixedly connected to the end of the first branch pipe, and the two ends of the connecting pipe are respectively fixedly connected to the front surface of the two hollow plates. The end of the second branch pipe is fixedly connected to the upper surface of the sealing plate. When the vacuum pump is working, the air inside the hollow plate is first drawn away, and the bag opening is adsorbed and fixed to the hollow plate through the adsorption hole. Secondly, when the sealing plate seals the opening of the placement cylinder, the air inside the placement cylinder and the packaging bag can be drawn away. After vacuum packaging is completed, the three-way valve is adjusted to make the inside of the placement cylinder and the hollow plate connected to the outside, so that the sealing plate and the placement cylinder can be separated, and the bag opening and the hollow plate can also be separated.

[0007] Preferably, a feed valve is fixedly installed on the upper surface of the sealing plate. When the sealing plate covers the opening of the placement cylinder, the recycled plastic particles can be loaded into the packaging bag through the feed valve.

[0008] Preferably, the placement cylinder is equipped with a weighing plate, which can be used to weigh the recycled plastic granules when they are put into the packaging bag.

[0009] Preferably, a base is fixedly installed on the lower surface of the placement cylinder, and a second hydraulic cylinder is fixedly installed inside the base. The output end of the second hydraulic cylinder is fixedly connected to the lower surface of the weighing plate. The second hydraulic cylinder drives the weighing plate to rise, so that the vacuum-packed packaging bag and recycled plastic granules move to the top of the placement cylinder for easy removal.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by incorporating a placement cylinder, a cylinder, a hollow plate, adsorption holes, an ultrasonic sealing plate, a fixing frame, a sealing plate, a first hydraulic cylinder, and a vacuum pump, facilitates vacuum packaging of recycled plastic granules. This improves sealing performance, prevents moisture absorption, and ensures the quality and effectiveness of the recycled plastic granules in later use. The first hydraulic cylinder raises the sealing plate, exposing the opening of the placement cylinder. The packaging bag is then inserted into the cylinder through the opening, and the bag opening is held in place by adsorption holes on the inner sides of the two hollow plates. This design ensures the packaging bag is properly sealed. The bag opening is opened, and recycled plastic granules are then inserted into the packaging bag through the opening. After the bag is filled, the first hydraulic cylinder drives the sealing plate to descend and seal the opening of the placement cylinder. Two cylinders drive two hollow plates to move in opposite directions, causing the opening of the packaging bag to close. The vacuum pump works to remove the air from the placement cylinder and the packaging bag. Then, the two cylinders drive the two hollow plates to continue moving in opposite directions and seal the opening of the packaging bag through two ultrasonic sealing plates. Finally, the first hydraulic cylinder drives the sealing plate to rise and reset, and the packaging bag and recycled plastic granules inside the placement cylinder can be removed.

[0012] 2. This utility model achieves the effect of facilitating the weighing of vacuum-packed recycled plastic granules and facilitating the removal of the vacuum-packed plastic granules from the placement cylinder by setting up a weighing plate and a second hydraulic cylinder. When the recycled plastic granules are put into the packaging bag, they can be weighed by the weighing plate. After vacuum packaging is completed, the second hydraulic cylinder drives the weighing plate to rise, so that the vacuum-packed packaging bag and recycled plastic granules move to the top of the placement cylinder for easy removal.

The output ends of the two cylinders 3 are fixedly connected to hollow plates 16. Adsorption holes 14 are provided on the inner side of the two hollow plates 16. The bag opening can be adsorbed and fixed to the inner side of the hollow plate 16 through the adsorption holes 14.

[0021] An ultrasonic sealing plate 15 is fixedly installed on the inner side of each of the two hollow plates 16 below the adsorption hole 14. The ultrasonic sealing plate 15 can seal the opening of the packaging bag. A three-way valve 11 is fixedly connected to the input end of the vacuum pump 8. A three-way pipe 12 is fixedly connected to the end of the three-way valve 11. The remaining two ends of the three-way pipe 12 are respectively fixedly connected to a first branch pipe 9 and a second branch pipe 13. A connecting pipe 10 is fixedly connected to the end of the first branch pipe 9. The two ends of the connecting pipe 10 are respectively fixedly connected to the front surface of the two hollow plates 16. The second branch pipe 13... The end is fixedly connected to the upper surface of the sealing plate 5. When the vacuum pump 8 is working, the air inside the hollow plate 16 is first drawn away, and the bag opening is adsorbed and fixed on the hollow plate 16 through the adsorption hole 14. Secondly, when the sealing plate 5 seals the opening of the placement cylinder 2, the air inside the placement cylinder 2 and the packaging bag can be drawn away. After the vacuum packaging is completed, the three-way valve 11 is adjusted to make the inside of the placement cylinder 2 and the hollow plate 16 connected to the outside, so that the sealing plate 5 and the placement cylinder 2 can be separated, and the bag opening can also be separated from the hollow plate 16.

[0022] In use, the first hydraulic cylinder 7 drives the sealing plate 5 to rise, exposing the opening of the placement cylinder 2. The packaging bag is inserted into the placement cylinder 2 through the opening, and the two sides of the bag opening are attracted and fixed by the suction holes 14 on the inner side of the two hollow plates 16, thus opening the bag opening. Then, recycled plastic granules are put into the packaging bag through the opening. After the bag is filled, the first hydraulic cylinder 7 drives the sealing plate 5 to fall and seal the opening of the placement cylinder 2. The two cylinders 3 drive the two hollow plates 16 to move in opposite directions, closing the bag opening. The vacuum pump 8 works to remove the air from the placement cylinder 2 and the packaging bag. Then, the two cylinders 3 drive the two hollow plates 16 to continue moving in opposite directions and seal the bag opening through the two ultrasonic sealing plates 15. Then, the first hydraulic cylinder 7 drives the sealing plate 5 to rise and reset, and the packaging bag and recycled plastic granules inside the placement cylinder 2 can be removed.
