Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag processing, in particular to a fully automatic packaging bag cutting machine. Background Art

[0002] A plastic packaging bag is a packaging bag made of plastic as raw material and used for various articles in production and life. It is widely used in daily life and industrial production. Commonly used plastic packaging bags are mostly made of polyethylene film. This film is non-toxic, so it can be used to hold food. When it is necessary to process and cut a polypropylene food packaging bag, a cutting machine will be used to cut it.

[0003] At present, when the cutting machine cuts the packaging bag, during the cutting process, friction will occur between the packaging bag and the blade of the cutting machine. This friction will cause the transfer of electrons, thus generating static electricity. The packaging bags will be adsorbed to the cutting knife due to static electricity, resulting in the packaging bags not being able to be cut normally by the cutting knife. Therefore, we propose a new type of fully automatic packaging bag cutting machine.

[0033] Please refer to Figures 1 to 5 , the present utility model provides a technical solution:

[0034] Embodiment 1

[0035] Such as Figures 1 to 5, the present utility model provides a fully automatic bag slitter, including support feet 1. At the top of the support feet 1, a transmission mechanism 2 is provided. Above the transmission mechanism 2, a bag cutting mechanism 3 is provided. Below the bag cutting mechanism 3, an anti-sticking mechanism 4 is provided. Outside the bag cutting mechanism 3, an anti-static mechanism 5 is provided. The anti-static mechanism 5 includes a guide rail 51. Inside the guide rail 51, a conductive sheet 52 is slidably connected. The number of conductive sheets 52 is two. Outside the conductive sheet 52, a conductive rod 53 is fixedly installed. At the bottom of the conductive rod 53, a conductive spring 54 is fixedly installed. At the lower end of the conductive spring 54, a conductive block 55 is fixedly installed. Outside the conductive block 55, an inclined support block 56 is fixedly installed. Below the conductive block 55, a grounding rod 57 is fixedly installed. The conductive block 55 is arranged between the conductive spring 54 and the grounding rod 57. The lower end of the grounding rod 57 is in contact with the ground. The conductive block 55 is located in the installation groove 24. The inclined support block 56 is fixedly connected to the transmission table 21. The conductive rod 53 horizontally penetrates the gantry 31. A copper bar 33 is fixedly installed between the two conductive sheets 52.

[0036] In this embodiment, by the combined use of the conductive sheet 52, the conductive rod 53, the conductive spring 54, the conductive block 55 and the grounding rod 57, using their conductivity, the free charges generated by the friction between the cutting knife 34 and the packaging bag can be introduced into the ground, making the cutting knife 34 equipotential with the ground, and the charges leak through the ground, thus eliminating static electricity. At the same time, the inclined support block 56 is used to fix the conductive block 55 to a specified position, and the conductive spring 54 can deform correspondingly as the cutting knife 34 moves up and down, so that the cutting knife 34 and the ground always maintain a conducting path to facilitate eliminating static electricity at all times.

[0037] Embodiment Two

[0038] As Figures 1 to 5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the transmission mechanism 2 includes a transmission table 21 fixedly installed at the top of the support feet 1. Above the transmission table 21, a base 22 is fixedly installed. Inside the base 22, a conveyor belt 23 is provided. An installation groove 24 is opened inside the transmission table 21. The bag cutting mechanism 3 includes a gantry 31 fixedly installed above the conveyor belt 23. At the center of the upper side of the gantry 31, a hydraulic cylinder 32 is fixedly installed. At the output end of the hydraulic cylinder 32, a copper bar 33 is fixedly installed. Below the copper bar 33, a cutting knife 34 is fixedly installed.

[0039] In this embodiment, the conveyor belt 23 can transport the packaging bag, facilitating the transportation of the packaging bag to directly below the cutting knife 34. The hydraulic cylinder 32 can provide power to drive the cutting knife 34 to move downward for slitting the packaging bag. At the same time, the copper bar 33 has good conductivity, facilitating the export of free charges on the cutting knife 34.

[0040] Embodiment Three

[0041] As Figures 1 to 5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the anti-sticking mechanism 4 includes anti-sticking rods 41 fixedly installed inside the base 22. The number of anti-sticking rods 41 is two, and the distance between the two anti-sticking rods 41 is greater than the transverse width of the cutting knife 34.

[0042] In this embodiment, through the anti-sticking rods 41, it can be ensured that when the cutting knife 34 cuts the packaging bag, even if the cutting knife 34 adheres to the packaging bag, the anti-sticking rods 41 can promptly separate the cutting knife 34 from the packaging bag.

[0043] During specific use, as a fully automatic packaging bag cutting machine, the present utility model places the packaging bag on the conveyor belt 23. The conveyor belt 23 transports the packaging bag. When the packaging bag is transported directly below the cutting knife 34, the conveyor belt 23 stops. The hydraulic cylinder 32 is started, and the hydraulic cylinder 32 drives the cutting knife 34 to move downward (the copper bar 33 and the conductive sheet 52 will move synchronously) to perform a cutting operation on the packaging bag. When static electricity is generated during the process of cutting the packaging bag, the conductive sheet 52 will conduct the charge on the cutting knife 34 to the conductive rod 53, the conductive rod 53 will conduct the charge to the conductive spring 54, the conductive spring 54 will conduct the charge to the conductive block 55, and the conductive block 55 will conduct the charge to the grounding rod 57. Finally, the charge will be transferred from the grounding rod 57 to the ground. By using the conductivity of the above-mentioned components, the free charge generated by the friction between the cutting knife 34 and the packaging bag is introduced into the ground, making the cutting knife 34 equipotential with the ground, and the charge leaks through the ground, thereby achieving the purpose of eliminating static electricity. Moreover, even if the cutting knife 34 adheres to the packaging bag for any reason, during the process of the cutting knife 34 retracting from the inside of the anti-sticking rod 41, the anti-sticking rod 41 will also separate the cutting knife 34 from the packaging bag.

[0044] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any simple changes, equivalent replacements, or modifications made on the basis of the present utility model to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present utility model.
