[0023] This specific embodiment is a cutting device for producing packaging bags, and its structural schematic diagram is as follows Figure 1 and Figure 2 shown, including a support frame 1 and a cutter 8. There are two groups of support frames 1. A support block 6 is installed between the two groups of support frames 1. The two sides of the support block 6 are circular-arc shaped. A cutting groove 12 is opened at the center position of the upper surface of the support block 6. A card slot 11 is opened on the side of one group of support frames 1. A limiting component 2 is installed on one group of support frames 1. A motor 3 is installed on the side of the support frame 1. The motor 3 is connected with a driving roller. A conveyor belt 4 is sleeved outside the driving roller. The other end of the conveyor belt 4 is sleeved with a driven roller 5. The driving roller and the driven roller 5 are adapted to the arc of the support block 6. The height of the support block 6 is adapted to the conveyor belt 4. A bottom block 7 is installed at the middle position between the two groups of support frames 1. A support plate 9 is installed on the upper surface of the bottom block 7. The support plate 9 is L-shaped. A cylinder 10 is fixedly penetrated through the horizontal end of the support plate 9. The lower end of the cylinder 10 is fixedly connected with the cutter 8. The position of the cutter 8 corresponds to that of the cutting groove 12. When cutting the wrapping paper, first adjust the limiting component 2 according to the width of the wrapping paper so that the limiting component 2 limits the wrapping paper. Then start the two motors 3. The motors 3 start to drive the driving roller to rotate. The driving roller rotates to drive the conveyor belt 4 to rotate. The conveyor belt 4 rotates to drive the driven roller 5 to rotate. Place the packaging cardboard on the conveyor belt 4 provided with the limiting component 2. Under the action of the conveyor belt 4, the packaging cardboard moves towards the support block 6. When starting the motor 3, start the cylinder 10 synchronously. The cylinder 10 starts to drive the cutter 8 to move up and down. When the cutter 8 moves downwards, it cuts the packaging cardboard, dividing the packaging cardboard into small pieces. The divided cardboard contacts the other conveyor belt 4 and is conveyed out of the device under the action of the conveyor belt 4.

[0024] Refer to Figure 1 and Figure 3 and Figure 4As shown in the figure, the limiting component 2 includes a connecting plate 201. The connecting plate 201 is fixedly installed at the lower end of the side surface of the support frame 1. The other end of the connecting plate 201 is connected to a box body 206. A chute 205 is provided on the upper surface of the box body 206. A screw rod 209 is rotatably penetrated through the box body 206. The screw rod 209 is connected to a disc 207. The disc 207 is rotationally connected to the box body 206 through the screw rod 209. Two groups of symmetrically distributed rotating rods 208 are installed outside the disc 207. The screw rod 209 is threadedly connected to a moving plate 202. The upper end of the moving plate 202 is connected to a limiting plate 203. The lower end of the limiting plate 203 contacts the conveyor belt 4. A limiting rod 204 is installed on the side surface of the limiting plate 203. The moving plate 202 is slidably adapted to the chute 205. The limiting plate 203 is snap-fitted to the card slot 11. Rotating the rotating rod 208, the rotation of the rotating rod 208 drives the disc 207 to rotate. The rotation of the disc 207 drives the screw rod 209 to rotate. The rotation of the screw rod 209 drives the moving plate 202 to horizontally move along the chute 205. The movement of the moving plate 202 drives the limiting plate 203 to disengage from the card slot 11. The movement of the limiting plate 203 makes the distance between the two limiting plates 203 smaller, so as to be adapted to the width of the wrapping paper. The limiting rod 204 provides limitation for the limiting plate 203 when the limiting plate 203 horizontally moves.

[0025] Working principle: When cutting the wrapping paper, first adjust the limiting component 2 according to the width of the wrapping paper so that the limiting component 2 limits the wrapping paper. The specific method is to rotate the rotating rod 208. The rotation of the rotating rod 208 drives the disc 207 to rotate. The rotation of the disc 207 drives the screw rod 209 to rotate. The rotation of the screw rod 209 drives the moving plate 202 to horizontally move along the chute 205. The movement of the moving plate 202 drives the limiting plate 203 to disengage from the card slot 11. The movement of the limiting plate 203 makes the distance between the two limiting plates 203 smaller, so as to be adapted to the width of the wrapping paper. The limiting rod 204 provides limitation for the limiting plate 203 when the limiting plate 203 horizontally moves. Through the setting of the limiting component 2, when transporting the wrapping paper, it is convenient to adjust the distance between the two limiting plates 203 according to the width of the wrapping paper, so as to facilitate the limitation of the wrapping paper, prevent the wrapping paper from deflecting during transportation, prevent deviation in the cutting of the wrapping paper, and thus reduce the defective rate of the production of the packaging bag;

[0026] Subsequently, two sets of motors 3 are started. The rotation of the motors 3 drives the rotation of the driving rollers, the rotation of the driving rollers drives the rotation of the conveyor belt 4, and the rotation of the conveyor belt 4 drives the rotation of the driven rollers 5. The packaging cardboard is placed on the conveyor belt 4 provided with the limiting component 2. Under the action of the conveyor belt 4, the packaging cardboard moves towards the direction of the support block 6. When the motor 3 is started, the cylinder 10 is started synchronously. The start of the cylinder 10 drives the cutter 8 to move up and down. When the cutter 8 moves downwards, it cuts the packaging cardboard, dividing the packaging cardboard into small pieces. The divided cardboard contacts another set of conveyor belts 4 and is conveyed out of the device under the action of the conveyor belts 4. By the combined use of the cutter 8 and the cylinder 10, it is convenient to divide the cardboard, facilitating the next step of folding the cardboard.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
