[0023] like Figure 1 As shown, a cutting device for processing plastic packaging bags includes a worktable 1 and a pair of rotating rollers 2. Table legs 3 are fixed at the four corners of the bottom of the worktable 1. The pair of rotating rollers 2 are installed above and below the worktable 1 in a linked manner (utilizing the idle space below the worktable 1 and reducing the height of the workpiece above the worktable 1). The linked rotating rollers 2 are used to pull the packaging bags on the worktable 1. A boss 4 is provided on one rotating roller 2 along its axis. The cross-section of the boss 4 is triangular and a cutting edge is provided on the top of the boss 4. A knife groove 5 is opened on the other rotating roller 2 along its axis. An A-slot 6 is opened on the worktable 1. The boss 4 is fitted into the knife groove 5 through the A-slot 6. Since the diameter of the rotating roller 2 is fixed, the length of the packaging bag cut by the boss 4 after one rotation can be precisely controlled, avoiding the need for workers to judge the length by eye, reducing the labor intensity of workers and improving the cutting efficiency.

[0024] In this embodiment, as Figure 1 and 2 As shown, a gate-shaped bracket 7 is installed on the workbench 1. A pair of cutters 8 are installed on the bracket 7 along the axial direction of the rotating roller 2. The pair of cutters 8 are used to cut the rough edges on both sides of the packaging bag. The bracket 7 is rotatably mounted above the workbench 1 via an ear seat 17. A limit block 18 is fixed on the ear seat 17. The limit block 18 is used to limit the rotation of the bracket 7. When a roll of packaging bag is cut and a new roll of packaging bag is put on for cutting, the bracket 7 is lifted and the packaging bag is fed into the rotating roller 2. After the bracket 7 is lowered, the rough edges of the new roll of packaging bag can be cut off by the cutters 8. The structure is simple and the material change is convenient.

[0025] In this embodiment, as Figure 1 As shown, a pair of support plates 9 are also fixed on the workbench 1. A connecting rod 10 is hinged on the support plate 9. The pair of support plates 9 are rotatably mounted to the pressure roller 11 through the connecting rod 10. The pressure roller 11 is located in the feeding area of ​​a pair of rotating rollers 2. The packaging bags in the feeding area of ​​the rotating rollers 2 are tightened by the pressure roller 11 to prevent the wrinkled packaging bags from entering the pressure roller 11, which would cause the length after cutting to be greater than the length designed for production.

[0026] In this embodiment, as Figure 1 and 3As shown, the clamping blocks 12 are slidingly installed on the support 7, the A through holes and the B through holes are formed on the clamping blocks 12 and do not intersect with each other, the A through holes are formed along the Y axis direction, the B through holes are formed along the X axis direction, the support 7 is inserted into the A through holes, the shanks of the cutters 8 are inserted into the B through holes, the A notches 13 and the B notches 14 are further formed on the clamping blocks 12, the A notches 13 are communicated with the A through holes, the B notches 14 are communicated with the B through holes, the A bolts 15 and the B bolts 16 are further screwed on the clamping blocks 12, the A bolts 15 are used for narrowing the A notches 13, the B bolts 16 are used for narrowing the B notches 14, the distance between the two clamping blocks 12 can be adjusted by unscrewing the A bolts 15, so as to adapt to the cutting requirements of the packaging bags with different widths.

[0027] In the embodiment, as shown in the figure, Figure 1 The spring 19 is installed between the support plate 9 and the connecting rod 10, the deformation of the spring 19 provides sufficient tension for the compression roller 11, so as to ensure the tightness of the packaging bag.

[0028] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
