[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In practice, plastic slitting requires unwinding and rewinding equipment. The unwinding equipment unwinds the plastic rolls, and the rewinding equipment rewinds the slit plastic fabric. However, in reality, installing the plastic rolls on the unwinding equipment and disassembling and replacing the rewinding device for the plastic fabric is quite troublesome, which reduces the efficiency of slitting plastic packaging bags. Therefore, there is an urgent need in this field to improve the plastic slitting machine for packaging bag processing, thereby solving the shortcomings of the existing technology. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a plastic slitting machine for packaging bag processing, which improves the efficiency of slitting plastic packaging bags.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a plastic slitting machine for packaging bag processing, comprising a supporting base plate, on which two sets of symmetrical fixed support plates and movable support plates are provided. A drive unit for driving the movable support plate to move on the supporting base plate is provided on one side of the supporting base plate.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-7A plastic slitting machine for packaging bag processing includes a base plate 1, on which two sets of symmetrical fixed support plates 2 and movable support plates 3 are provided. A drive unit 4 for driving the movable support plates 3 to move on the base plate 1 is provided on one side of the base plate 1. A fixed shaft 9 passing through the movable support plate 3 is rotatably connected to one side of the fixed support plates 2. A first drive motor 5 for driving the fixed shaft 9 to rotate is fixedly installed on one side of the fixed support plates 2. Two symmetrical fixed plates 6 are fixedly installed on the upper part of the base plate 1. A rotating shaft 7 is rotatably connected between the two fixed plates 6. Several slitting blades 8 for slitting are provided on the side of the rotating shaft 7. 9 are used to fix the roll material to be slit and several take-up reels 10 respectively. A second drive motor 11 for driving the rotating shaft 7 to rotate is fixedly installed on one side of a fixed plate 6. A tensioning wheel 12 for tensioning the conditions to be slit is provided on the upper part of the bearing base plate 1. The drive unit 4 includes a third drive motor 20 fixedly installed on one side of the bearing base plate 1. Sliding blocks 21 are fixedly installed on the lower ends of the two movable support plates 3. A sliding groove 22 adapted to the sliding block 21 is opened on the upper part of the bearing base plate 1. A drive screw 23 with one end fixedly installed to the output end of the third drive motor 20 is rotatably connected in the sliding groove 22. The drive screw 23 passes through the sliding block 21 and is threadedly connected to it.

[0031] Specifically, when the plastic roll of packaging bag needs to be slit, two third drive motors 20 are started. The output end of the third drive motor 20 drives the drive screw 23 to rotate. The rotation of the drive screw 23 drives the sliding block 21 to move in the sliding groove 22. The sliding block 21 drives the movable support plate 3 to move. The movable support plate 3 disengages from the fixed shaft 9. The plastic roll of packaging bag is then fitted onto the side of one of the fixed shafts 9 by a lifting device. The winding reel 10 for winding is fitted onto the side of the other fixed shaft 9. The fixed shaft 9 can be an air shaft or other shaft that can provide a fixing effect, as is currently available. Then, the third drive motor 20 drives the movable support plate 3 in the reverse direction. The movable support plate 3 moves and fits onto one side of the fixed shaft 9, completing the slitting of the packaging bag. The fixing of the plastic roll and the take-up reel 10 is performed in the same way as its disassembly, which facilitates the assembly and disassembly of the plastic roll and the take-up device. Then, one of the first drive motors 5 is started to drive the plastic roll of the packaging bag to unwind. The plastic roll of the packaging bag is coiled around the side of the tension wheel 12 to the side of several slitting discs 8. It extends to the position of the take-up reel 10 through the slitting of the slitting discs 8. First, the slitting of the plastic roll of the packaging bag is manually coiled around the side of the take-up reel 10. Then, another first drive motor 5 is started to drive several take-up reels 10 to rotate. At the same time, the second drive motor 11 is started to drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives several slitting discs 8 to rotate, thereby slitting the plastic roll of the packaging bag. The take-up reel 10 then winds it up.

[0032] As a technical optimization of this utility model, two symmetrical first fixing columns 13 are fixedly installed on the upper part of the bearing base plate 1. Both ends of the tensioning wheel 12 are rotatably connected to the positioning seat 14. A limiting column 15 that penetrates the positioning seat 14 is fixedly installed on the upper end of the first fixing column 13. A spring 16 located between the first fixing column 13 and the positioning seat 14 is sleeved on the side of the limiting column 15.

[0033] Specifically, the tensioning wheel 12 is rotatably connected between the two positioning seats 14. The height of the tensioning wheel 12 is higher than that of the rotating shaft 7. The plastic of the packaging bag exerts a downward pulling force on the tensioning wheel 12. When the tensioning wheel 12 moves downward, the spring 16 is under pressure. At the same time, the spring 16 exerts an upward pushing force on the positioning seats 14, thereby achieving the tensioning effect on the plastic of the packaging bag. The limiting post 15 limits the position of the positioning seats 14 and prevents the spring 16 from undergoing radial deformation.

[0034] As a technical optimization of this utility model, a fixing ring 17 is fixedly installed on each of the opposite sides of the slitting disc 8. A limiting bolt 18 is threaded through and connected to one end of the fixing ring 17. A limiting groove 19 adapted to the end of the limiting bolt 18 is opened on the side of the rotating shaft 7.

[0035] Specifically, when it is necessary to cut plastic packaging bags into different widths, the position of the slitting disc 8 is adjusted by sliding the fixing ring 17 on the side of the rotating shaft 7. After the position of the slitting disc 8 is adjusted, the limiting bolt 18 is locked. One end of the limiting bolt 18 abuts against the inner wall of the limiting groove 19 to limit and fix the position of the slitting disc 8. At the same time, the limiting groove 19 limits the position of the limiting bolt 18, which can cut plastic packaging bags into different widths and improve the applicability of the slitting machine.

[0036] As a technical optimization of this utility model, a slitting auxiliary roller 24 adapted to several slitting discs 8 is provided between the two fixed plates 6. A fourth drive motor 29 for driving the slitting auxiliary roller 24 to rotate is provided on one side of the fixed plate 6. Adjusting seats 25 are rotatably connected to both ends of the slitting auxiliary roller 24. An adjustment groove 26 adapted to the adjustment seat 25 is opened through the fixed plate 6. An adjustment threaded rod 27 with one end rotatably connected to the upper part of the adjustment seat 25 is threaded through and threaded to the upper end of the fixed plate 6. A limit nut 28 is threadedly connected to the upper side of the adjustment threaded rod 27. A scale plate 33 with scale is fixedly installed on the side of the fixed plate 6. The scale plate 33 is adapted to the position of the adjustment groove 26.

[0037] Specifically, the slitting auxiliary roller 24 guides and presses the plastic of the packaging bag, and the fourth drive motor 29 is activated to drive the slitting auxiliary roller 24 to rotate, improving the slitting effect of the plastic of the packaging bag. By rotating the adjusting threaded rod 27, the adjusting seat 25 moves within the adjusting groove 26. When the adjusting seat 25 moves, the distance between the slitting auxiliary roller 24 and the slitting blade 8 is adjusted. The position of the slitting auxiliary roller 24 is determined by observing the scale on the scale plate 33. Then, the position of the adjusting seat 25 is fixed by locking the limiting nut 28. This allows for the slitting of plastic packaging bags of different thicknesses, thus improving the applicability of the slitting machine.

[0038] As a technical optimization of this utility model, a number of symmetrical second fixed columns 30 are fixedly installed on the upper part of the bearing base plate 1. A fixed frame 31 is fixedly installed on the upper part of the second fixed columns 30. An auxiliary positioning roller 32 is rotatably connected inside the fixed frame 31. The rotation of the auxiliary positioning roller 32 limits the plastic of the packaging bag during the conveying process, preventing the plastic of the packaging bag from shifting during the conveying process and causing the cutting size to shift.
