Description

Technical Field

[0001] This utility model relates to the technical field of waste collection, specifically to a waste collection device for packaging bag production. Background Technology

[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during production and distribution. They are widely used in daily life and industrial production. A large amount of waste is generated during the production of packaging bags, and collection devices are needed to handle the waste.

[0003] An existing waste collection device for medical composite film packaging bags, such as the one with patent publication number CN212472528U, uses a lifting hydraulic rod to raise and lower a lifting mesh frame, and a lowering hydraulic rod to lower the mesh frame, to compress the packaging bag waste. This replaces the traditional manual collection method, thereby improving the efficiency of the workers. By blowing hot air onto the compressed packaging bag waste with a hot air blower, the surface of the packaging bag waste can be thermally melted and shrunk, thus packaging and compressing the packaging bag waste. This reduces the space occupied by the packaging bag waste and makes it easier for workers to collect and put away.

[0004] However, the process generates a certain amount of harmful gases, which can cause certain harm to workers. In addition, the output temperature of the hot air blower is high when it is working for a long time, which may ignite the packaging bag, making it impractical. Utility Model Content

When the waste in the collection filter 8 needs to be cleaned, the three-way valve 1 4 and the three-way valve 2 11 are adjusted to form a passage between the main inlet pipe 3, the backup collection mechanism, the backup outlet pipe 12, and the air pump 9. The waste can be collected by the backup collection mechanism, forming a closed loop for the collection outer barrel 7, which facilitates the removal and cleaning of the collection filter 8.

[0024] The backup collection mechanism includes a backup outlet pipe 12, a backup inlet pipe 13, an internally threaded cap 14, a backup collection outer cylinder 15, an externally threaded port 16, a backup collection filter cartridge 17, and a connecting frame 18. The rear middle side of the collection outer cylinder 7 is connected to the front side of the backup collection outer cylinder 15 via the connecting frame 18. The backup collection filter cartridge 17 is detachably installed inside the backup collection outer cylinder 15. The top end of the backup collection outer cylinder 15 is connected to the bottom end of the externally threaded port 16. The outer side of the externally threaded port 16 is detachably threaded to the inner side of the internally threaded cap 14.

[0029] In summary, when using a waste collection device for packaging bag production, the waste absorption guide hood 2 is fixed to the corresponding work position via the outer connecting frame 1 for absorbing waste. Specifically, the collection filter 8 is installed inside the collection outer barrel 7, and the top cover 5 is closed on the top of the collection outer barrel 7. Turning the locking handle 19 causes the moving pin 20 to rotate and pin into the fixed pin frame 21, thus closing and fixing the top cover 5. The sealing ring gasket 22 ensures a sealed contact after the top cover 5 is closed, preventing air leakage. The collection outer barrel 7 acts as a connecting part. By adjusting the three-way valve 4 and the three-way valve 11 respectively, a passage is formed between the main inlet pipe 3, the collection outer barrel 7, the air outlet pipe 10, and the air pump 9. When the air pump 9 is running, the waste absorption guide hood 2 absorbs the waste under negative pressure and collects it inside the collection outer barrel 7. The waste is collected by the collection filter 8 and the air is discharged by the air pump 9. When the waste in the collection filter 8 needs to be cleaned, the three-way valve 14 and the three-way valve 211 can be adjusted to form a passage between the main inlet pipe 3, the spare collection outer cylinder 15, the spare outlet pipe 12 and the air pump 9. The spare collection filter 17 is installed in the spare collection outer cylinder 15. The inner threaded cover 14 is screwed closed on the outside of the outer threaded opening 16. The sucked-in waste can be collected in the spare collection filter 17 and the air is discharged by the spare outlet pipe 12, forming a closed circuit for the collection outer cylinder 7, which makes it convenient to remove the collection filter 8 for cleaning. In addition, the air pump 9 can be connected through the connecting seat 23 to fix the position of the air pump 9 relative to the collection outer cylinder 7. The observation window 24 can be used to observe from the outside to the inside, which makes it convenient to judge the internal condition of the collection outer cylinder 7 and deal with it in time.
