[0028] like Figures 1 to 5 As shown;

[0029] Combining the above:

[0030] The cardboard cutting device with a protective structure is characterized in that a hydraulic telescopic rod 3 is fixed on the top of a gantry 2, the output end of the hydraulic telescopic rod 3 penetrates the gantry 2 and extends into the gantry 2, a cutting knife 4 is slidably connected in the middle of the gantry 2, the output end of the hydraulic telescopic rod 3 is fixedly connected to the cutting knife 4, a protective component is installed on the surface of the gantry 2, the protective component includes a collecting hood 9 fixed on the left side of the gantry 2, the collecting hood 9 is a rectangular cover structure, a plurality of ventilation holes are opened in the upper half of the collecting hood 9, and a shielding cover 8 is fixed on the right side of the gantry 2, the shielding cover 8 is an arched plate-like structure.

[0031] In this embodiment: when the utility model is performing a cutting operation, the hydraulic telescopic rod 3 drives the cutting knife 4 to cut the edge of the cardboard. The pressure-bearing base 1 is a T-shaped casting, which can withstand a large impact force. The cut burrs fall into the collecting cover 9. The collecting cover 9 with a concave bottom can collect the burrs. The collecting cover 9 can prevent the operator from accidentally putting his hand into the cutting knife 4, thereby protecting the operator and preventing external debris from damaging the cutting knife 4. The shielding cover 8 can prevent debris from entering the end position of the cardboard.

[0032] It should be noted that the hydraulic telescopic rod 3 is connected to an external hydraulic pump (not shown in the figure).

[0033] Going further:

[0034] In an optional embodiment, a propulsion assembly is provided on the right side of the pressure base 1, and the propulsion assembly includes a propulsion platform 5 and an electric push rod A6 fixed to the middle of the surface of the propulsion platform 5, and a propulsion plate 7 is fixed to the output end of the electric push rod A6, and the surface of the propulsion platform 5 is flush with the surface of the pressure base 1.

[0035] In this embodiment: through this design, when performing paper cutting operations, the cardboard is placed on the surface of the L-shaped pushing plate 7, and the electric push rod A6 is started. The electric push rod A6 pushes the cardboard to move to the cutting knife 4. The operator can remotely control the pushing process through the control module (not shown in the figure), which further improves safety. After cutting is completed, the electric push rod A6 is controlled to retract and reset, and the cardboard can be taken out, which is convenient for safely removing the cardboard.

[0036] Going further:

[0037] In an optional embodiment, a paper pressing assembly is installed on the right side of the gantry 2, and the paper pressing assembly includes a fixed plate 10 fixed to the outer wall of the gantry 2, an electric push rod B11 is fixed to the bottom side of the fixed plate 10, the electric push rod B11 passes through the top of the shielding cover 8, and a clamping plate 12 is fixed to the output end of the electric push rod B11.

[0038] In this embodiment: through this design, when the cardboard is pushed to the cutting knife 4, the control module starts the electric push rod B11, and the electric push rod B11 extends to drive the pressing plate 12 to move down, press the cardboard, make the cardboard fixed and stable, and then cut it, which can make the cardboard stable during the cutting process and avoid the cardboard from deflecting during cutting.

[0039] Going further:

[0040] In an optional embodiment, a support seat 13 is fixed to the upper surface of the fixed plate 10 , and the support seat 13 is fixedly connected to the outer side wall of the gantry 2 .

[0041] In this embodiment: through this design, since the electric push rod B11 applies downward pressure to the cardboard, the support seat 13 on the surface of the fixed plate 10 can support the fixed plate 10 to prevent the reaction force from acting on the fixed plate 10 and causing the fixed plate 10 to deform.

[0042] Going further:

[0043] In an optional embodiment, the bottom of the collecting hood 9 is a bucket-shaped structure, and a dust collector 14 is provided on one side of the collecting hood 9. The dust collector 14 is connected to the collecting hood 9 through a bellows.

[0044] In this embodiment: through this design, when cutting, the vacuum cleaner 14 can extract the cardboard burrs in the collection cover 9, which is convenient for cleaning the collection cover 9, so that the utility model can be used for a long time and prevent paper scraps from affecting the cutting of the cardboard.

[0045] Going further:

[0046] In an optional embodiment, a shearing groove 15 is provided on the surface of the pressure-bearing base 1 corresponding to the lower portion of the cutting blade 4 , and a rubber pad is engaged in the shearing groove 15 .

[0047] In this embodiment: through this design, the blade of the cutting knife 4 can be moved into the shearing groove 15, so that the cardboard can be fully cut to avoid the situation where the cardboard is not cut, and the rubber pad can protect the blade of the cutting knife 4.

[0048] Working principle and use process of the utility model: When the utility model is cutting, the cardboard is placed on the surface of the L-shaped pushing plate 7, and the electric push rod A6 is started. The electric push rod A6 pushes the cardboard to move to the cutting knife 4. The operator can remotely control the pushing process through the control module (not shown in the figure), which further improves safety. After the cutting is completed, the electric push rod A6 is controlled to retract and reset, and the cardboard can be taken out, which is convenient for safe removal of the cardboard. After the cardboard is pushed to the cutting knife 4, the control module starts the electric push rod B11, and the electric push rod B11 extends to drive the pressing plate 12 to move downward, press the cardboard, make the cardboard fixed and stable, and then cut, so that the cardboard can be cut in the cutting process. The utility model is stable, and the deviation of the cardboard during cutting is avoided, and then the cutting is carried out. During cutting, the cutting knife 4 is driven by the hydraulic telescopic rod 3 to cut the edge of the cardboard. The pressure-bearing base 1 is a T-shaped casting, which can withstand a large impact force. The cut burrs fall into the collecting cover 9, and the collecting cover 9 with a concave bottom can collect the burrs. The collecting cover 9 can prevent the operator from accidentally putting his hand into the cutting knife 4 to protect the personnel, and can prevent the cutting knife 4 from being damaged by external debris. The shielding cover 8 can prevent the cardboard from entering the end position. The cardboard burrs in the collecting cover 9 can be extracted by the vacuum cleaner 14, which is convenient for cleaning the collecting cover 9, so that the utility model can be used for a long time to avoid paper scraps affecting the cutting of the cardboard.
