[0002] Honeycomb paperboard is an environmentally friendly and energy-saving material made based on the honeycomb structure principle found in nature. It is made by bonding corrugated paper into countless hollow three-dimensional regular hexagons to form a paper core, and then bonding face paper to both sides to create this new type of sandwich structure board. However, in the actual production process, a cutting device is needed to cut the long strips of honeycomb paperboard into the required length.

[0003] The existing technology has the following problems:

[0004] In existing honeycomb paperboard cutting devices, when the honeycomb paperboard is placed on the operating table, if the operator touches it unintentionally, it will cause the position to shift, resulting in positional deviation during cutting. In addition, it is inconvenient to clean dust or dirt from the surface of the honeycomb paperboard during cutting. Furthermore, the blades in existing honeycomb paperboard cutting devices are fixed in design, making it inconvenient to disassemble and replace them, resulting in troublesome and laborious blade replacement.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1: As Figures 1 to 5 As shown, this utility model provides a honeycomb cardboard cutting device, including an operating table 1. Baffles 2 are fixedly connected to the front and rear sides of the upper surface of the operating table 1. Through the arrangement of the baffles 2 and the cardboard positioning components 8 on the left and right sides, a limiting cavity is formed, facilitating the clamping and fixing effect of the cardboard positioning components 8 on the honeycomb cardboard. A toothed plate 3 is fixedly connected to the upper side of one side of each of the front and rear baffles 2. Through the cooperation of the toothed plate 3 and the motor 41, the U-shaped frame 4 moves, allowing for position adjustment according to actual conditions. The U-shaped frame 4 is slidably connected to the upper surface of the front and rear operating tables 1. A hydraulic cylinder 6 is fixedly connected to the middle of the horizontal direction of the U-shaped frame 4. A [missing information - likely a device or component] is located below the output end of the hydraulic cylinder 6. The cutting blade 7 is activated by the hydraulic cylinder 6 and pushed to cut the honeycomb cardboard on the upper surface of the operating table 1. Cardboard positioning components 8 are provided on the left and right sides of the opposite surfaces of the front and rear baffles 2. The cardboard positioning components 8 are used to clamp and fix the honeycomb cardboard. A positioning rod 5 is slidably connected through the vertical direction of the U-shaped frame 4. The design of the positioning rod 5 ensures that the U-shaped frame 4 can only move horizontally left and right, preventing the U-shaped frame 4 from disengaging from the baffles 2. The upper surface of the front and rear baffles 2 is provided with grooves. The inside of the grooves is fixedly connected to the two ends of the positioning rod 5. The grooves facilitate the installation of the positioning rod 5.

[0027] Two motors 41 are fixedly connected to the U-shaped frame 4 in a mirror image in the vertical direction. The output ends of the two motors 41 are fixedly connected to gears 42. The outer surface of the gears 42 meshes with the outer surface of the rack plate 3. The front and rear baffles 2 and the rack plate 3 form an L-shape and are set in a mirror image. The motors 41 are electrically connected to the power supply through wires, which facilitates the starting of the motors 41. When the motors 41 move, they will drive the gears 42 to rotate. Due to the setting of the rack plate 3, the movement of the U-shaped frame 4 is effective, and the position can be easily adjusted.

[0028] Example 2: Figures 1 to 5As shown, the cardboard positioning assembly 8 includes a U-shaped baffle 81. The vertically opposite surfaces of the U-shaped baffle 81 are each provided with a mounting groove. The mounting grooves are designed to facilitate the vertical sliding of the plate 84. Springs 82 are fixedly connected to the left and right sides of the mounting grooves. The plate 84 is slidably connected inside the mounting grooves. The upper end of the spring 82 is fixedly connected to the lower surface of the plate 84. The elasticity of the spring 82 causes the plate 84 to move upwards. Through the cooperation of the positioning post 85 and the positioning hole 22, the position of the honeycomb cardboard is restricted after clamping. Brushes 83 are fixedly connected to the opposite sides of 84 and U-shaped baffle 81. The upper and lower brushes 83 are of the same length. Before use, the honeycomb paperboard is placed between the upper and lower brushes 83 and moved by pushing the honeycomb paperboard. During the movement, the upper and lower brushes 83 clean the dust on the surface of the honeycomb paperboard. After cleaning, the honeycomb paperboard enters between the left and right U-shaped baffles 81. Positioning posts 85 are fixedly connected to the front and rear of the upper surface of the plate 84. The positioning posts 85 cooperate with the positioning holes 22 to perform the positioning function.

[0029] Two L-shaped grooves 21 are mirror-imagely formed on the lower surface of the opposite side of the front and rear baffles 2. The interior of the front and rear L-shaped grooves 21 is slidably connected to the outer surface of the cardboard positioning assembly 8. Several positioning holes 22 are formed on the upper surface of the inner wall of the front and rear L-shaped grooves 21. The interior of the positioning holes 22 is inserted into the outer surface of the positioning post 85. This structure facilitates the left and right movement of the U-shaped baffle 81, making it convenient to clamp and fix honeycomb cardboard of different sizes. After the honeycomb cardboard is cut, the user presses the positioning post 85 to cause the spring 82 to retract, causing the positioning post 85 to separate from the positioning hole 22, so as to facilitate the movement of the U-shaped baffle 81 and make it easy to remove the honeycomb cardboard.

[0030] Example 3: Figures 1 to 5As shown, a mounting plate 73 overlaps the upper surface of the cutting blade 7. The middle of the upper surface of the mounting plate 73 is fixedly connected to the output end of the hydraulic cylinder 6. The design of the mounting plate 73 facilitates the installation and removal of the cutting blade 7. Two L-shaped blocks 71 are fixedly connected to the upper surface of the cutting blade 7 in a mirror image. The inner sides of the two L-shaped blocks 71 overlap with the outer surface of the mounting plate 73. The structure of the L-shaped blocks 71 prevents the cutting blade 7 from falling downwards after installation. The horizontally opposite surfaces of the front and rear L-shaped blocks 71 are provided with blocking grooves. The blocking grooves facilitate the limiting of the blocking blocks 75 and prevent the cutting blade 7 from sliding left and right. The opposite surfaces of the front and rear blocking grooves are provided with slots 72 for inserting... The slot 72 facilitates the insertion of the T-shaped plate 77 into the horizontal outer surface, further defining the positions of the connecting plate 74 and the blocking block 75. The upper surface of the mounting plate 73 is movably connected to the connecting plate 74 at both the front and rear. The end face of the connecting plate 74 is fixedly connected to the blocking block 75, and the outer surface of the blocking block 75 overlaps with the inside of the blocking slot. This structure achieves the limiting effect after the cutting blade 7 is installed. The end face of the blocking block 75 is fixedly connected to the arc-shaped elastic plate 76, and the end face of the arc-shaped elastic plate 76 is fixedly connected to the T-shaped plate 77. The horizontal outer surface of the T-shaped plate 77 is inserted into the inside of the slot 72. This structure prevents the blocking block 75 from easily moving within the blocking slot, thus improving stability.

[0031] Working principle: During use, by pushing the honeycomb paperboard, the upper and lower brushes 83 clean the dust on the surface. After cleaning, the honeycomb paperboard falls onto the upper surface of the operating table 1, and the honeycomb paperboard is positioned between the left and right U-shaped baffles 81. By pressing the plate 84, the spring 82 contracts, and the positioning post 85 separates from the positioning hole 22. Then, by moving the left and right U-shaped baffles 81, the honeycomb paperboard is clamped. After clamping, the worker releases the plate 84, and the spring 82 resets, causing the positioning post 85 to re-insert into the positioning hole 22 for limiting. Then, the hydraulic cylinder 6 is activated to drive the cutting blade 7 to move downward to facilitate the cutting of the honeycomb paperboard.

[0032] When the cutting blade 7 needs to be replaced, the hydraulic cylinder 6 is in the closed state. The worker pushes the T-shaped plate 77 to separate the horizontal outer surface of the T-shaped plate 77 from the inside of the slot 72. Then, the worker flips the connecting plate 74 and the blocking block 75 to separate the blocking block 75 from the blocking groove in the L-shaped block 71. Then, the worker moves the cutting blade 7 to separate the L-shaped block 71 from the mounting plate 73, thus completing the disassembly and replacement operation.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
