[0030] Refer to Figure 1-6 ,

[0031] A corrugated cardboard cross-cutting device includes: a conveying pressure roller 1, a driving member 2, a cutting member 3, and a pushing member 4.

[0032] The conveying pressure roller 1 is arranged on a workbench 5 forming a supporting surface 51, and the conveying pressure roller 1 cooperates with the supporting surface 51 of the workbench 5 to press the corrugated cardboard. The driving member 2 is used to drive the conveying pressure roller 1 to rotate. The rotation of the conveying pressure roller 1 will drive the corrugated cardboard to move on the workbench 5, thereby realizing the movement of the corrugated cardboard. The cutting member 3 is used to cut the corrugated cardboard. A receiving groove 11 is formed in the conveying pressure roller 1, and the cutting member 3 is arranged in the receiving groove 11. The pushing member 4 is used to push the cutting member 3 outwards relative to the receiving groove 11 to a first position and retract it inwards to a second position; when the cutting member 3 is in the first position, the rotation of the conveying pressure roller 1 can cut the corrugated cardboard through the cutting member 3; when the cutting member 3 is in the second position, the rotation of the conveying pressure roller 1 can only convey the corrugated cardboard. In this embodiment, the cutting member 3 can be a cutter, the pushing member 4 can be one of a cylinder, a hydraulic cylinder, and an electric push rod, and the driving member 2 is a motor.

[0033] By adopting the above technology, when the cutting member 3 is in the second position, the conveying pressure roller 1 rotates to drive the corrugated cardboard to move. After the corrugated cardboard is moved to a suitable position, the pushing member 4 moves the cutting member 3 to the first position. The cutting member 3 is equivalent to a cutter body formed on the conveying pressure roller 1, and the corrugated cardboard can be cut when the conveying pressure roller 1 rotates.

[0034] In actual application, the cutting member 3 can be in the second position, the conveying pressure roller 1 rotates several circles, and then the cutting member 3 is in the first position, and the conveying pressure roller 1 rotates one circle, so as to realize the adjustment of the position where the corrugated cardboard needs to be cross-cut.

[0035] In some embodiments, a stop block 6 is provided in the receiving groove 11, and a through groove 62 is formed in the stop block 6; the pressing and cutting member 3 is pushed outwards through the through groove 62 to a first position and retracted inwards to a second position; the pressing and cutting member 3 includes: a cutting portion 31 and a mounting portion 32; the width of the cutting portion 31 matches that of the through groove 62; an elastic member 7 is provided between the mounting portion 32 and the stop block 6, and the pushing member 4 is used to apply an inward retracting thrust to the mounting portion 32. The cutting portion 31 is a blade, and the mounting portion 32 is a block for mounting the blade.

[0036] Specifically, an arc surface 61 is formed at one end of the stop block 6 facing away from the elastic member 7; the radian of the arc surface 61 matches the radian of the outer wall surface of the conveying pressure roller 1. During the rotation of the conveying pressure roller 1, the contact area between the conveying pressure roller 1 and the corrugated cardboard is greatly increased.

[0037] Specifically, a support plate 8 is provided on the workbench 5; the driving member 2 includes a rotary power structure and a transmission rotating shaft 25; the transmission rotating shaft 25 is rotatably connected to the support plate 8, and the rotary power structure is used to drive the transmission rotating shaft 25 to rotate. The rotary power structure includes a driving motor 21, a first gear 22, a second gear 23 and a motor bracket 24. The motor bracket 24 is fixed on the support plate 8, the first gear 22 is connected to the output end of the driving motor 21, the second gear 23 is connected to the transmission rotating shaft 25, the driving motor 21 is installed on the motor bracket 24, the first gear 22 meshes with the second gear 23, and the driving motor 21 drives the transmission rotating shaft 25 to rotate through the first gear 22 and the second gear 23 in sequence.

[0038] Specifically, the pushing member 4 includes: a linear power structure 45, a first transmission structure 41 and a second transmission structure 43; the linear power structure 45 drives the mounting portion 32 and the cutting portion 31 to be pushed outwards to a first position through the first transmission structure 41 and the second transmission structure 43 in sequence.

[0039] Specifically, the first transmission structure 41 forms a transmission inclined surface 42; the second transmission structure 43 forms an abutting surface 44; the first transmission structure 41 is close to the conveying roller, and the transmission inclined surface 42 drives the second transmission structure 43, the mounting portion 32 and the cutting portion 31 to be pushed outwards to a first position through the abutting surface 44.

[0040] Specifically, a protruding portion 26 is formed on the transmission rotating shaft 25; the first transmission structure 41 is sleeved on the transmission rotating shaft 25 and is slidably connected to the transmission rotating shaft 25.

[0041] Among them, the linear power structure 45 is an electric push rod, the first transmission structure 41 is a block, and the second transmission structure 43 is a rod. The second transmission structure 43 is fixed to the mounting portion 32, and the first transmission structure 41 is slidably connected to the transmission rotating shaft 25 and the protruding portion 26. The linear power structure 45 is used to drive the first transmission structure 41 to move closer to and away from the conveying pressure roller 1. The transmission inclined surface 42 abuts against the abutting surface 44. When the first transmission structure 41 moves closer to the conveying pressure roller 1, the transmission inclined surface 42 pushes the second transmission structure 43 away from the transmission rotating shaft 25, and the second transmission structure 43 drives the mounting portion 32 and the cutting portion 31 to move to the first position. A universal ball is installed on the output end of the linear power structure 45, and the output end of the linear power structure 45 is pushed outwards, that is, the universal ball contacts the first transmission structure 41 to drive the first transmission structure 41 to move closer to the conveying pressure roller 1.

[0042] In addition, the output end of the linear power structure 45 retracts inwards, that is, the universal ball moves away from the conveying pressure roller 1, so that the first transmission structure 41 is no longer subjected to a thrust force. At this time, the elastic member 7 applies a thrust force to the mounting portion 32, so that the mounting portion 32 and the cutting portion 31 move to the first position. The first transmission structure 41 moves together with the mounting portion 32, and the abutting surface 44 of the first transmission structure 41 abuts against the transmission inclined surface 42 to reset the first transmission structure 41.
