Description

Technical Field

[0001] The invention relates to the technical field of packaging bag production, and in particular to a bag making machine used for packaging bag production. Background Art

[0002] Packaging bags are widely used in industries such as medicine and food. When producing packaging bags, plastic particles are generally melted by an extruder and then cooled and inflated by a film blowing device. The film is then prepared into a tube film through a traction device and a reel device, and then heat-sealed and cut into bags. In the production process of packaging bags, plastic particles need to be blown to form the required plastic film, so plastic particles need to be added to the blow molding machine. At present, most of them are transported by a feeder, and the bags containing plastic particles need to be manually opened, and then the plastic particles are poured into the feeder. In this process, the plastic particles need to be transported and disassembled manually, which is not only time-consuming and labor-intensive, but also inefficient. A plastic particle feeder for packaging bag production and processing disclosed by Patent No. CN213107694U replaces the manual bag unpacking and feeding process, which saves time and labor and improves production efficiency.

[0003] However, in order to quickly unpack the bags, whether it is manual unpacking or using a plastic pellet feeding machine for packaging bag production and processing in the above-mentioned patent, the bags are cut open by a knife.

[0027] A method for using a bag making machine for producing packaging bags, applicable to the above-mentioned bag making machine for producing packaging bags, comprises the following steps: S1, using the bag opening component 3 to cut the package bag containing the plastic particles, and the plastic particles in the package bag enter the material mixing mechanism 5 through the cut opening; S2, the material leveling mechanism 5 disperses the incoming plastic particles and spreads the plastic particles evenly inside the chip removal mechanism 2; S3, when the plastic particles pass through the chip removal mechanism 2, the airflow flowing from bottom to top in the chip removal mechanism 2 will sweep away the debris in the plastic particles and discharge them from the top of the chip removal mechanism 2; S4, the clean plastic particles enter the conveying mechanism 4 and are discharged at a uniform speed.

[0028] In this embodiment, when in use, the package bag is placed on the top of the multiple sleeves 351, and then one of the push-pull rods 353 is pulled to make the transfer mechanism 35 carry the package bag and move from one side of the inner wall of the box bucket 31 to the other side. During this process, the bottom of the package bag located on the top of the multiple sleeves 351 will be cut by the multiple blades 343 during the movement. As the package bag is cut, the plastic particles contained in the package bag are dumped from the opening of the package bag into the box bucket 31 and enter the transition pipe 51 through the curved pipe 32. The plastic particles enter the transition pipe 51 through the circular inlet 511 and enter the circular pipe 52 through the rectangular outlet 512. The started motor 2 54 drives the rotating shaft 53 to rotate continuously during the working process. The rotating rotating shaft 53 discharges the plastic particles entering the circular pipe 52 from the discharge port 521 in equal amounts through the plurality of blades 531. The plastic particles discharged from the discharge port 521 fall on the top of the sieve plate 26. The plastic particles falling on the top of the screen plate 26 will be evenly spread along the inclined screen plate 26 and roll toward the gathering cover 28. During this process, the airflow blown by the fan 24 will blow toward the screen plate 26 from bottom to top. Under the blowing of the airflow from bottom to top, the debris generated by cutting the package bag mixed in the plastic particles will float up and be discharged from the chassis 21 through the chip discharge pipe 27. Afterwards, the plastic particles roll along the inclined screen plate 26 toward the gathering hood 28 and enter the port of the conveying pipe 42 through the gathering of the gathering hood 28. Then, under the rotation of the conveying auger 43 driven by the motor 44, the plastic particles enter the conveying pipe 42 and enter the discharge pipe 45 under the conveyance of the conveying auger 43 and are finally discharged through the discharge pipe 45.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
