Description

Technical Field

[0001] This utility model relates to the technical field, and more specifically, to a paper cutting mechanism for producing paper honeycomb core equipment. Background Technology

[0002] Paper honeycomb board is a type of paperboard material composed of multiple honeycomb-shaped sheets. Its paper principle is mainly based on the honeycomb structure technology used in the paper product manufacturing process. Honeycomb paper is generally formed and cured by molding equipment.

[0003] Existing paper honeycomb paperboard includes honeycomb paper and face paper bonded to both sides of the honeycomb paper to form paper honeycomb paperboard. In the production process, the paper needs to be cut into strips. The cut strips are then bonded together to form the honeycomb paper core. A cutting device is required during the paper cutting process. The cutting device includes a cutting frame and a cutting blade mounted on the cutting frame. The cutting blade is equipped with a drive cylinder, which drives the cutting blade to move up and down. During the up and down movement, the paper that moves below the cutting blade is cut. The cut strips are then manually packaged, and finally, the packaged strips are placed into subsequent equipment for further processing.

[0004] In the aforementioned related technologies, paper can be cut by moving the cutting blade up and down. However, during the cutting process, the cutting blade needs to move up and down, and the paper is subjected to downward pressure. This causes the paper to deform during the cutting process, resulting in a decrease in the pass rate of the cut strips of paper. Utility Model Content

[0005] To address at least one of the aforementioned problems, this utility model provides a paper cutting mechanism for a paper honeycomb core production equipment.

[0006] A paper cutting mechanism for a paper honeycomb core production device includes a cutting frame and a cutting assembly mounted on the cutting frame. The cutting assembly includes an electric slide rail mounted on the cutting frame, a mounting bracket slidably connected to the electric slide rail, and an annular cutting blade mounted on the mounting bracket. The electric slide rail, mounting bracket, and annular cutting blade move along the width direction of the paper. The annular cutting blade cuts the paper during forward movement and continues to cut the paper during reverse movement.

[0007] Optionally, the mounting frame is provided with a clamping wheel, the clamping wheel is rotatably connected to the mounting frame, the annular cutting blade is fixed on the clamping wheel, and the cutting platform is provided with a receiving groove for accommodating the annular cutting blade.

[0008] Optionally, the cutting frame is provided with a paper-pulling assembly for pulling the paper to be cut to the area below the cutting assembly.

A gap is provided between the paper-pulling rollers and the paper-pulling rollers for the paper to pass through. The paper-pulling rollers and the paper-pulling rollers are used to abut against the surface of the paper. The cutting frame is provided with a pulling motor for driving the paper-pulling rollers to rotate.

[0009] Optionally, the cutting frame is provided with a pressing assembly, which includes a pressing roller rotatably connected to the cutting frame, a first pressing plate fixed to the pressing roller, and a pressing motor provided on the cutting frame.

Detailed Implementation

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-6 This application will be described in further detail.

[0015] This utility model embodiment provides a paper cutting mechanism for a paper honeycomb core production equipment, referring to... Figures 1 to 6 A paper cutting mechanism for a paper honeycomb core production equipment includes a cutting frame 01 and a cutting component 1 mounted on the cutting frame 01. A paper pulling component 2 is mounted on the cutting frame 01 to pull the paper to be cut to the underside of the cutting component 1, and then the paper is cut by the cutting component 1. In addition, a pressing component 3 is mounted on the cutting frame 01 to press the end of the paper to be cut. A cutting platform is mounted on the cutting frame 01 to place the paper to be cut. After the paper is cut, the workers pack the cut paper and then move it to the subsequent equipment.

[0016] The cutting assembly 1 includes an electric slide rail 11 mounted on the cutting frame 01, a mounting bracket 12 slidably connected to the electric slide rail 11, and an annular cutting blade 13 mounted on the mounting bracket 12. Under the action of the electric slide rail 11, the mounting bracket 12 and the annular cutting blade 13 mounted on the mounting bracket 12 can move along the width direction of the paper, thereby reducing the downward pressure on the paper during cutting, resulting in better paper slitting and improving the paper slitting pass rate. In this embodiment, the annular cutting blade 13 is configured as an annular structure.

[0017] During the paper cutting process, the electric slide rail 11 drives the mounting frame 12 and the annular cutting blade 13 to move back and forth. The paper can be cut during the forward movement of the annular cutting blade 13, and the paper can still be cut during the reverse movement of the annular cutting blade 13, thereby improving work efficiency.

[0018] A pressure roller 02 is provided on the mounting frame 12, and the pressure roller 02 is rotatably connected to the mounting frame 12. Simultaneously, the annular cutting blade 13 is fixed to the pressure roller 02. A receiving groove 03 is provided on the cutting platform to accommodate the annular cutting blade 13. During the movement of the annular cutting blade 13, it is positioned within the receiving groove 03, facilitating paper cutting. During the movement of the mounting frame 12, the pressure roller 02 can press down on the ends of the paper, thereby reducing wrinkles during cutting.

[0019] The paper pulling assembly 2 includes a paper pulling roller 21 rotatably connected to the cutting frame 01 and a plurality of paper pressing rollers 22 rotatably connected to the cutting frame 01. The cutting frame 01 is provided with a pulling motor (not shown in the figure) for driving the paper pulling roller 21 to rotate. The paper pulling roller 21 is arranged along the width direction of the paper, and the plurality of pressing rollers 02 are spaced apart along the width direction of the paper. A gap is provided between the paper pressing rollers 22 and the paper pulling roller 21 for the paper to pass through. At the same time, the paper pulling roller 21 and the paper pressing rollers 22 abut against the surface of the paper. By rotating the paper pulling roller 21, the paper can be pulled forward under the action of the paper pressing rollers 22, so that the paper can be moved to the bottom of the annular cutting blade 13.

[0020] The clamping assembly 3 includes a clamping roller 31 rotatably connected to the cutting frame 01, a first clamping plate 32 fixed to the clamping roller 31, and a clamping motor (not shown in the figure) disposed on the cutting frame 01. In this embodiment, the first clamping plate 32 is fixed to the clamping roller 31 by bolts, and the output shaft of the clamping motor is fixed to the clamping roller 31. The clamping motor drives the clamping roller 31 to rotate, and the clamping roller 31 drives the first clamping plate 32 to abut against the end of the paper on the worktable. Then, during cutting, the paper wrinkles can be reduced, and the stability of the paper after cutting can be improved.

[0021] A second pressing plate 6 is provided on the cutting frame 01. The second pressing plate 6 is slidably connected to the cutting frame 01 in the vertical direction. When the annular cutting blade 13 moves along the width direction of the paper, the surface of the pressing wheel 02 abuts against the surface of the second pressing plate 6 to ensure that the paper does not move or warp.

[0022] The implementation principle of the paper cutting mechanism of the paper honeycomb core production equipment in this application embodiment is as follows: When cutting the paper, the paper is passed between the paper pull roller 21 and the paper pull wheel. The paper pull roller 21 rotates and drives the paper to be cut to move below the annular cutting blade 13. Then, the annular cutting blade 13 is driven to move along the length direction of the paper by the electric slide rail 11. During the movement, the paper is cut. The paper can be cut during the reciprocating movement of the annular cutting blade 13, thereby improving the paper cutting efficiency. In addition, since the cutting is carried out along the width direction of the paper, compared with the existing technology of cutting from top to bottom, the deformation and wrinkles of the paper can be reduced, and the qualified rate of the cut paper can be improved.
