[0024] The utility model provides Figure 1-4 A cutting device for producing paper product packaging boxes shown includes a cutting table 1, and an automatic waste collection mechanism is provided on the upper end of the cutting table 1;

[0025] The automatic waste collection mechanism includes two limit slides 2 opened on one side of the top of the cutting table 1, a push plate 3 is slidably provided between the inner walls of the two limit slides 2, two electric telescopic rods 4 are fixedly provided at both ends of the push plate 3, and two clamping plates 5 are fixedly provided at the output ends of the four electric telescopic rods 4. A feed trough 6 is opened on the other side of the top of the cutting table 1, and a conveyor belt 7 is provided at one end of the inner wall of the feed trough 6. A discharge trough 8 is opened in the middle position of one side of the outer wall of the cutting table 1, and a limit stopper is opened on one side of the cutting table 1 at the lower end of the discharge trough 8. The inner wall of the card slot 9 is interspersed with a collecting box 10, and when the push plate 3 pushes the stack of cardboards, the cardboard part that needs to be cut off is just located on the conveyor belt 7. When it is cut off, the conveyor belt 7 is started to bring it into the feed trough 6, and the feed trough 6 is in an inclined state. The feed trough 6 is connected to the inner wall of the discharge trough 8. The collecting box 10 is located below the discharge trough 8. After the waste is discharged from the discharge trough 8, it directly falls into the collecting box 10, and the conveyor belt 7 is made of metal material and will not be cut by the cutting blade 19;

[0026] Furthermore, a groove 11 is provided at the top of the cutting table 1 in the middle of the two limiting slide grooves 2, a rack 12 is inserted through the inner wall of the groove 11, and one side of the top of the rack 12 is fixedly connected to the bottom of the push plate 3, and a support frame 13 is fixedly provided at the top of the cutting table 1 above the groove 11.

[0027] The inner wall of the support frame 13 is rotatably provided with a gear 14, and the outer wall of the gear 14 is meshed with the outer wall of the rack 12. A motor 15 is fixedly provided on one side of the support frame 13, and one end of the gear 14 passes through the inner wall of the support frame 13 and is fixedly connected to the output end of the motor 15. According to the size of the paperboard of the paper product packaging box to be cut as needed, the motor 15 is started to rotate the gear 14 and then mesh the rack 12 to adjust the position of the push plate 3 to different degrees, so that the push plate 3 pushes the paperboard to the lower end of the cutting blade 19, so that the device can adjust the pushing distance according to the size of the paperboard;

[0028] Furthermore, the cutting mechanism with a limiting function includes a mounting bracket 16 fixed on the top of the cutting table 1, and hydraulic cylinders 17 are fixed on both sides of the top of the mounting bracket 16. Connecting shafts 18 are inserted at the output ends of the two hydraulic cylinders 17, and the outer walls of the two connecting shafts 18 are respectively inserted and connected with the inner walls of the mounting bracket 16.

[0029] A cutting blade 19 is fixedly provided at the bottom of the two connecting shafts 18 , and a connecting frame 20 is sleeved on the outer wall of the two connecting shafts 18 .

[0030] An extrusion plate 21 is fixedly provided at the bottom of the two connecting frames 20, and a spring 22 is sleeved on the outer wall of one end of the two connecting shafts 18, and the two ends of the two springs 22 are respectively fixedly connected to the top of the cutting blade 19 and the bottom of the two connecting frames 20. When the cutting blade 19 descends with the connecting shaft 18, the extrusion plate 21 is pressed on the upper end of the cardboard and the connecting shaft 18 stretches the spring 22. After cutting, the connecting shaft 18 rises with the blade, and the extrusion plate 21 rises together with it under the elastic support of the spring 22, without affecting the replacement of the cardboard.

[0031] Working principle: When using the cutting device for producing paper product packaging boxes in the present design, firstly, the stack of cardboards needs to be placed on the cutting table 1 so that it is close to one side of the push plate 3, and then the electric telescopic rods 4 at both ends of the push plate 3 are started to clamp the edges of the two sides of the cardboard with the clamping plates 5 on both sides, and the motor 15 is started to drive the gear 14 to rotate in the support frame 13 and then engage the rack 12 for transmission, and the rack 12 drives the push plate 3 to slide in the limiting slide groove 2 and then push the stack of cardboards to the bottom of the cutting blade 19, and the excess part is cut off in cooperation with the cutting of the blade. When cutting the edge material of the cardboard, the edge material is located at the upper end of the conveyor belt 7. After it is cut off by the cutting blade 19, the conveyor belt 7 is started to drive the waste material to the upper end of the feed trough 6 and move it to fall into the feed trough 6, slide from the feed trough 6 to the discharge trough 8 at the lower end and fall into the collection box 10, and through the collection The collecting box 10 is collected, and the collecting box 10 is slid out of the limiting card slot 9 later to process the waste therein. The staff does not need to operate the cutting table 1 to cut the cardboard while collecting and cleaning the cut waste, which improves the convenience of using the device. When cutting the cardboard, the hydraulic cylinder 17 at the upper end of the mounting bracket 16 is started to make the connecting shaft 18 with the cutting blade 19 descend to cut the stacked cardboard at the lower end. Before the cutting blade 19 contacts the cardboard, the squeezing plate 21 connected by the connecting frame 20 first contacts the cardboard and squeezes the cardboard, and then while squeezing, the connecting shaft 18 continues to stretch the spring 22 to descend so that the cutting blade 19 cuts the cardboard, so that while cutting, the structure can also assist the clamping plate 5 to squeeze and fix the upper side of the stacked cardboard to prevent the cardboard from deviating during the cutting process and causing a large error in cutting, thereby improving the cutting quality of the device.
