[0052] In this embodiment, one end of the sliding seat 33 is slidably connected to the sliding shaft 4, and a protruding ear is welded on the upper end of the sliding seat 33, and a spline sleeve 32 is movably connected to the inner side of the protruding ear through a bearing; the spline sleeve 32 is slidably connected to the spline shaft 2, and a transmission gear 31 is installed on the spline sleeve 32 with an interference fit;

[0053] There are two transmission gears 31, and the other transmission gear 31 is mounted on the sliding sleeve 35. The two transmission gears 31 are connected by a toothed belt 34. One end of the spline shaft 2 is connected to the first transmission unit 1 by transmission.

[0054] By adopting the above technical solution, when the first transmission unit 1 drives the spline shaft 2 to rotate, the spline sleeve 32 follows the spline shaft 2 to rotate in the sliding seat 33. At this time, the sliding sleeve 35 is driven to rotate through the cooperation of the transmission gear 31 and the toothed belt 34, so that the first crimping and grooving knife 36 can rotate.

[0055] In this embodiment, a positioning bolt 10 is further provided at the rear side of the connection between the sliding seat 33 and the sliding shaft 4 .

[0056] By adopting the above technical solution, the position of the sliding seat 33 can be adjusted along the sliding shaft 4. After the adjustment is completed, the locking bolt 10 can prevent the sliding seat 33 from sliding by itself.

[0057] In this embodiment, a keyway is provided at the shaft hole of the second crimping and slotting knife 7, and is in transmission and sliding connection with the key on the transmission shaft 6; the transmission shaft 6 is in transmission connection with the mating shaft 5 through the meshing of two gears;

[0058] The transmission shaft 6, the matching shaft 5, the spline shaft 2 and both ends of the matching shaft 5 are all mounted in cooperation with the frame body 12 through seat bearings.

[0059] By adopting the above technical solution, the mating shaft 5 drives the transmission shaft 6 to rotate through the meshing of two gears, thereby realizing the rotation of the second creasing and slotting knife 7, so as to cooperate with the first creasing and slotting knife 36 to creasing and slot the cardboard.

[0060] In this embodiment, the frame body 12 is provided with a side of the transmission shaft 9 and a retaining frame 19 is fixed thereto. The retaining frame 19 is used to block the loading of paperboards, and the paperboards are loaded through the loading assembly.

[0061] The loading assembly includes a material rack 14, on which two slide grooves 15 are provided; the slide grooves 15 are slidably connected to a push rack 18, and the bottom of the push rack 18 is connected to a push plate 16 via two fixing rods passing through the slide grooves 15; the push plate 16 is fixed to the cylinder rod of the cylinder 17; and the cylinder 17 is fixed to the bottom of the material rack 14.

[0062] By adopting the above technical solution, when in use, firstly, the stack of cardboards is placed between the two side upright plates 20. When loading, the cylinder rod of the air cylinder 17 contracts and pulls the push plate 16 inward. Under the traction of the push plate 16, the push frame 18 pushes the lowest cardboard in the stack of cardboards to move toward the transmission shaft 9. Due to the obstruction of the stop frame 19 and the gap between the stop frame 19 and the upper surface of the material rack 14 that can only allow one cardboard to pass, the push frame 18 can only push one cardboard to slide at a time, thereby realizing the loading of cardboards one by one.

[0064] When the cardboard is pushed halfway, the cardboard enters between the two transmission shafts 9. Driven by the transmission shaft 9, the cardboard can be transported between the first crimping and slotting knife 36 and the second crimping and slotting knife 7. Since the push frame 18 is always located at the bottom of the stack of cardboards, it can be easily reset without paper jams, so that the cardboards can be loaded one by one in an orderly manner.

[0065] In this embodiment, a material guide plate 13 is provided inside the frame body 12 , and the material guide plate 13 is located outside the second crimping and grooving knife 7 ; a controller 11 is also fixed outside the frame body 12 .

[0066] The working principle of the utility model is as follows: when in use, firstly, the stack of cardboards is placed between the two side upright plates 20. When loading, the cylinder rod of the air cylinder 17 contracts and pulls the push plate 16 inward. Under the traction of the push plate 16, the push frame 18 pushes the lowest cardboard in the stack of cardboards to move toward the transmission shaft 9; due to the obstruction of the stop frame 19, and the gap between the stop frame 19 and the upper surface of the material frame 14 can only allow one cardboard to pass, the push frame 18 can only push one cardboard to slide at a time, thereby realizing the loading of the cardboards one by one; when the cardboard is pushed halfway, the cardboard enters between the two transmission shafts 9, and driven by the transmission shaft 9, the cardboard can be transported to between the first crimping and slotting knife 36 and the second crimping and slotting knife 7;

[0067] When the first transmission unit 1 drives the spline shaft 2 to rotate, the spline shaft sleeve 32 rotates in the sliding seat 33 following the spline shaft 2. At this time, the sliding shaft sleeve 35 is driven to rotate through the cooperation of the transmission gear 31 and the toothed belt 34, so as to rotate the first crimping and slotting knife 36; the matching shaft 5 drives the transmission shaft 6 to rotate through the meshing of two gears, thereby realizing the rotation of the second crimping and slotting knife 7, so as to cooperate with the first crimping and slotting knife 36 to crimp and slot the cardboard;

[0068] The crimping ring 362 on the outside of the first disc 361 cooperates with the crimping groove 72 on the outside of the second disc 71, so that the cardboard can be crimped. This double-disc crimping can form positive and negative grooves, which is convenient for folding the cardboard; when the slotting knife 363 after the first disc 361 rotates one circle and the knife groove 73 after the second disc 71 rotates one circle, the cardboard can be slotted; the above structure integrates crimping and slotting, which greatly improves the processing efficiency of the cardboard.
