Description

Technical Field

[0001] The present application relates to the technical field of plastic packaging machines, and particularly to a plastic packaging machine. Background Art

[0002] Generally, after a plastic packaging bag packs the material items, it needs to be sealed and cut by relevant equipment. That is, the plastic bag is sealed, and the excess material at the sealed end is cut off.

[0003] The existing Chinese patent with the publication number CN215476130U discloses a sealing and cutting device for a plastic packaging machine, including a conveying table. A protective cover is fixedly connected to the top of the conveying table. Two moving rods are arranged on the top surface inside the protective cover. A moving ring is fixedly connected to the bottom of the two moving rods. Tooth grooves are formed on the front and rear surfaces of the inner wall of the moving ring. An adjusting cutting device is arranged at the bottom of the moving ring, and a driving device is arranged inside the protective cover. When the gear meshes with the tooth groove on the rear surface inside the moving ring, it drives the moving ring to move left. When the moving ring moves left, it drives the adjusting cutting device to move left. When the gear meshes with the tooth groove on the front surface inside the moving ring, it drives the moving ring to move right. When the moving ring moves right, it drives the adjusting cutting device to move right, thereby completing the cutting of the plastic packaging. This not only improves the efficiency of plastic packaging sealing and cutting, but also improves the safety and practicality of the device.

[0004] However, the above plastic packaging machine has the following disadvantages: By setting an adjusting cutting mechanism, the adjusting cutting device moves left and right, thereby completing a reciprocating motion for cutting. However, static electricity is generated during the cutting of plastic packaging, making the surface of the cutting knife carry static charges. This will cause the plastic chips and fragments generated by cutting to adhere to the surface of the tool. At the same time, static electricity will increase the friction and static adsorption between the tool and the plastic packaging, reducing the cutting efficiency.

[0005] Therefore, we propose a plastic packaging machine to solve this problem.

[0006] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

The soft cloth 9 is in contact with the blade surface of the cutting knife 15. A driving mechanism is arranged in the first chute; by providing the anti-static pulsed ion wind rod 20 and the soft cloth 9, the static electricity on the tool surface is released, reducing the friction and static electricity adsorption between the tool and the plastic packaging, and at the same time reducing the adhesion of plastic fragments during cutting, thereby reducing the cleaning work and maintenance frequency, improving the cutting efficiency, and then using the soft cloth 9 to gently clean the tool surface to remove slight residues or impurities on the surface of the cutting knife 15, ensuring the cleanliness and smoothness of the tool surface to improve its service life.

[0021] Referring to Figures 1-2 , the driving mechanism includes a screw rod 17 and a motor 12. The screw rod 17 is rotatably installed in the first chute. The screw rod 17 penetrates through the first slider 13, and the screw rod 17 is threadedly connected to the first slider 13. One side of the protective cover 1 is fixedly installed with the motor 12, and the output end of the motor 12 is drivingly connected to the screw rod 17, which can drive the first slider 13 to move, thereby driving the telescopic dust removal mechanism to move.

[0022] Referring to Figures 1-3 , limiting grooves 11 are provided on both sides of the connecting column 3. The two limiting grooves 11 are communicated with the second chute.

[0025] The implementation principle of an embodiment of this application's plastic packaging machine is as follows: During use, start the first hydraulic cylinder 2. The first hydraulic cylinder 2 pushes the connecting frame 4 downward. The connecting frame 4 drives two second sliders 10 downward. The two second sliders 10 drive the telescopic column 5 downward. The telescopic column 5 drives the support plate 7 and the second hydraulic cylinder 6 downward. The support plate 7 drives the soft cloth 9 and the static elimination pulse ion wind rod 20 downward. Then start the second hydraulic cylinder 6. The second hydraulic cylinder 6 pushes the support plate 7 to move towards one side of the cutting knife 15. The support plate 7 drives the soft cloth 9 and the static elimination pulse ion wind rod 20 close to the cutting knife 15. Before removing static electricity, firmly install the rod body and the supporting high-voltage power supply. Insert the high-voltage plug of the rod body into the high-voltage output connection socket of the supporting high-voltage power supply, and connect the grounding terminal of the rod body to the grounding stud of the high-voltage power supply. Turn on the power switch. The switch indicator light is on, indicating that the power supply is working. Positive and negative ions will be generated at the electrode needles to neutralize the static electricity on the surface of the object. At the same time, start the motor 12. The motor 12 drives the screw rod 17 to rotate. The screw rod 17 drives the first slider 13 to move. The first slider 13 drives the telescopic dust removal mechanism to move, eliminating the static electricity contained on the surface of the cutting knife 15 after cutting plastic. At the same time, it drives the mounting seat 8 and the soft cloth 9 to move, gently cleaning the cutting knife 15 after static electricity elimination, and removing slight residues or impurities on the surface of the cutting knife 15.
