An upper template 6 is sleeved inside the second mounting groove 51, and a plurality of second plug holes 63 are provided on both sides of the upper template 6, and the plurality of second plug holes 63 are arranged in an array. An insertion rod 18 is snap-fitted to the inside of each second plug hole 63, and the outer wall of the upper template 6 is snap-fitted to the inner wall of the second mounting groove 51 via a plurality of insertion rods 18. A cutter 61 is fixedly connected to the middle part of one side of the upper template 6, and a gasket 62 is provided on the outer side and the inner side of the cutter 61, and one side of the gasket 62 is fixedly connected to one side of the upper template 6. A bottom plate 3 is provided on one side of the bottom of the cutter 61, and the inner walls of the four corners of the bottom plate 3 are fixedly connected to the legs of the positioning bracket 2. A mounting groove 31 is provided on one side of the top of the bottom plate 3, and the lower template 4 is connected to the inside of the mounting groove 31 by snapping. Multiple plug holes 42 are provided at both ends of the lower template 4, and the inside of each plug hole 42 is snap-connected with an insertion rod 18, and the lower template 4 is snap-connected to the inner wall of the mounting groove 31 through multiple insertion rods 18. A knife groove 41 is provided on one side of the top of the lower template 4, and one side of the upper template 6 is attached to one side of the lower template 4 through the movable plate 5, and the cutter 61 is snap-connected to the inner wall of the knife groove 41 through the upper template 6. And one end of the multiple insertion rods 18 is fixedly connected to the push plate 17, and one side of each push plate 17 is fixedly connected to multiple electric push rods 16, and the multiple electric push rods 16 are arranged in an array.

The plurality of inserting rods 18 are slidably connected to the inner walls of both sides of the installation groove 31 and the cutting blade 61 via the electric push rod 16 .

[0027] During operation, when the produced packaging bags need to be cut, the packaging bag material strip is passed between the bottom plate 3 and the movable plate 5, and the material strip is attached to the top of the lower template 4. Then the hydraulic push rod 7 is used to push the movable plate 5 down, and the four corners of the movable plate 5 are connected to the legs of the positioning bracket 2 to prevent the movable plate 5 from being misplaced when moving. The upper template 6 can be stably attached to the top of the lower template 4, and then the cutter 61 is inserted into the inside of the knife groove 41, and the cutting of the material strip is completed by the cutter 61. The gasket 62 is then used to press the edge of the cutting position to prevent the material strip from wrinkling during cutting, thereby ensuring the cutting effect of the packaging bag. After the cutting is completed, the movable plate 5 is lifted by the contraction of the hydraulic push rod 7, so that the upper template 6 is separated from the lower template 4, and then the material strip is moved, and the above steps are repeated to complete the cutting of the packaging bag.

The outer wall of each driven wheel 13 is rotatably connected to a transmission belt 14, and the inner wall of the other end of each transmission belt 14 is rotatably connected to another driven wheel 13. And the other driven wheel 13 is fixedly connected to one end of a smoothing roller 11, and the smoothing roller 11 rotates inside the rectangular rod 10 through the driven wheel 13 and the transmission belt 14.

[0029] During operation, the material strip is passed through the two smoothing rollers 11, and then the drive motor 15 is started. The output shaft of the drive motor 15 is used to drive the driven wheel 13 to rotate, and the rotation of the driven wheel 13 is used to drive the transmission belt 14 to rotate, so that the other driven wheel 13 rotates synchronously. A smoothing roller 11 is driven to rotate inside the rectangular rod 10, and then the two adjacent smoothing rollers 11 are meshed by the transmission gear 12, so that the material strip can be driven to move on the top of the bottom plate 3, and the cutting position of the material strip can be adjusted automatically. The smoothing rollers 11 at both ends can not only transport the material strip, but also smooth it, reducing the occurrence of wrinkles during cutting, and improving the practicality and efficiency of the equipment.

In addition, the use of multiple positioning slide bars 8 can improve the anti-seismic effect of the equipment, reduce the jamming of the movable plate 5 when moving, and increase the service life of the equipment.

[0032] Working principle: insert the lower template 4 and the upper template 6 into the grooves at both ends of the installation groove 31 and the second installation groove 51, and then push the lower template 4 and the upper template 6 so that they are completely in contact with the inner wall of the installation groove 31 and the second installation groove 51. Then use the electric push rod 16 to push the push plate 17 to reinsert the multiple insertion rods 18 into the inside of the socket 42 and the second socket 63, so that the lower template 4 and the upper template 6 are fixed on one side of the bottom plate 3 and the movable plate 5. When the produced packaging bags need to be cut, the packaging bag material strip is passed between the bottom plate 3 and the movable plate 5, and respectively passed between the two smoothing rollers 11 at both ends, so that the material strip is in contact with the top of the lower template 4. Use the hydraulic push rod 7 to push the movable plate 5 down, use the connection between the four corners of the movable plate 5 and the feet of the positioning bracket 2, and use the connection between the reset spring 9 and the inner wall of the corner of the movable plate 5 to further ensure the stability of the movable plate 5. The upper template 6 can be stably attached to the top of the lower template 4, and then the cutter 61 is inserted into the inside of the knife groove 41, and the cutter 61 is used to complete the cutting of the material strip. The gasket 62 is then used to press the edge of the cutting position to prevent wrinkles in the material strip during cutting. After the cutting is completed, the movable plate 5 is lifted by the contraction of the hydraulic push rod 7, so that the upper template 6 is separated from the lower template 4. Then the drive motor 15 is started, and the output shaft of the drive motor 15 is used to drive the driven wheel 13 to rotate, and the rotation of the driven wheel 13 is used to drive the transmission belt 14 to rotate, so that the other driven wheel 13 rotates synchronously. A smoothing roller 11 is driven to rotate inside the rectangular rod 10 respectively, and then the meshing of the transmission gear 12 is used to make the two adjacent smoothing rollers 11 rotate synchronously, which can drive the material strip to move on the top of the bottom plate 3, and the adjustment of the material strip cutting position can be automatically completed. Repeat the above steps to complete the cutting of the packaging bag.
