Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a cardboard cutting machine for cardboard printing. Background Art

[0002] Cardboard printing is a process of transferring information such as patterns and words to the surface of cardboard through specific printing equipment and processes. As a common packaging material, cardboard is widely used in the packaging of various products due to its low cost, recyclability, environmental protection, etc. Before cardboard printing, it is necessary to cut the printed cardboard, and it is cut into paper of the required specifications by a cardboard cutting machine for printing.

[0003] The cardboard cutting machines on the market include automatic paper cutting machines and manual paper cutting machines. Among them, the manual paper cutting machine, as a common office equipment, mainly includes a frame, a knife holder, a paper cutting knife, a paper clamping component, a paper pushing handle and a cutting table. The working principle is to place the paper to be cut on the cutting table and fix it with a pressure cardboard (or paper clamping component). According to the length and angle to be cut, a locator is used for positioning. The user pushes the paper pushing handle to make the paper cutting knife move downward. When the paper cutting knife contacts the paper, the sharp blade starts to cut the paper. As the paper pushing handle is continuously pushed, the paper cutting knife gradually penetrates into the paper and finally cuts it off. When the paper cutting knife reaches the bottom, the paper is completely cut off. At this time, the pressure cardboard (or paper clamping component) can be released and the cut paper can be taken out.

[0004] At present, in order to cut the cardboard, the paper cutting knife of the manual paper cutting machine generally opens a cutting slot corresponding to the paper cutting knife on the workbench below the paper cutting knife. When cutting the paper, the paper cutting knife enters the cutting slot to completely cut off the cardboard. For example, the cardboard cutting machine of model DC-3204SQ. Although the setting of this cutting slot is convenient for the paper cutting knife to cut off the cardboard, a large amount of shredded paper will be generated when the paper cutting knife cuts the paper, and it will also fall into the cutting slot. With the accumulation over a long time, the cutting slot will be blocked, thus affecting subsequent paper cutting. It requires the staff to clean it with tools such as brushes and iron wires, which is relatively time-consuming and laborious.

[0005] Therefore, it is necessary to design a cardboard cutting machine for cardboard printing that is convenient for cleaning. Summary of the Utility Model

Specific implementation manner

[0022] Example 1 is given by Figures 1-5 A cardboard cutting machine for cardboard printing includes a cutting seat 3 fixed on a workbench 1. An adjusting paper blocking structure 2 is vertically installed on one side edge of the cutting seat 3. A paper cutting knife structure 4 is fixedly installed on the back of the cutting seat 3. Below the paper cutting knife structure 4, a cutting groove 5 is formed on the top surface of the workbench 1. An auxiliary collection structure 6 is arranged on one side of the cutting groove 5;

[0023] In this embodiment, the cardboard cutting machine is a Downton manual paper cutting machine with the model DC-3204SQ. The specific mechanism compositions of the adjusting paper blocking structure 2, the cutting seat 3 and the paper cutting knife structure 4 are prior art and do not need to be described in detail. The working principle is mainly based on the movement of the blade to cut the paper. When the user pushes the paper pushing handle, the paper cutting knife will move downward to cut the paper. When the paper cutting knife reaches the bottom, the paper will be cut off. This process is repeated until all the required papers are cut.

[0024] Specifically, stack the printed cardboard together, place it on the workbench 1, and limit and adjust the printed cardboard on the workbench 1 through the adjusting paper blocking structure 2 so that the cutting position is in the cutting seat 3, below the paper cutting knife structure 4. Next, hold the pull rod of the paper cutting knife mechanism and apply force downward to drive the blade downward to cut the printed cardboard. The blade and the cut shredded paper enter the cutting groove 5.

[0025] The auxiliary collecting structure 6 includes a displacement groove and a movable plate 61 connected to the cutting groove 5. Sliding grooves 612 are provided on the top of both sides of the displacement groove. Moving blocks 615 are slidably connected inside the two sliding grooves 612. The moving blocks 615 are fixedly connected to the ends of both sides of the movable plate 61. A guide rod 613 is fixed at one end of the moving block 615. The guide rod 613 extends through the workbench 1. The outside of the guide rod 613 is located in the sliding groove 612 and is sleeved with a spring 614. A discharge cavity 63 is provided inside the workbench 1 to communicate with the cutting groove 5 and the displacement groove.

[0026] A pull handle 611 is fixed to the outer end of the movable plate 61 , and the pull handle 611 is installed on the movable plate 61 to facilitate pulling out the movable plate 61 .

[0027] Specifically, as the number of paper scraps in the cutting groove 5 increases, the user can grab the handle 611 to pull the movable plate 61 to move. The movable plate 61 is subjected to force and moves in the sliding groove 612 through the moving block 615. The guide rod 613 extends out of the workbench 1, and the internal spring 614 is squeezed and contracted. At this time, the movable plate 61 moves backward to expose the displacement groove, thereby expanding the space of the cutting groove. The paper scraps inside the displacement groove fall into the discharge chamber 63 for storage due to the change in space, so that the cutting groove 5 is connected, and there is no need to spend time manually cleaning the cutting groove 5, which is relatively time-saving and labor-saving. Release the handle 611, the spring 614 rebounds and drives the guide rod 613 and the moving block 615 to return, so that the movable plate 61 returns to cover the displacement groove.

[0028] Embodiment 2, on the basis of embodiment 1, the discharge chamber 63 passes through the side end of the workbench 1 and is connected to the outside, and a pushing mechanism 62 is slidably connected inside the discharge chamber 63. The pushing mechanism 62 includes a movable groove 631 opened on the workbench 1 and connected to the discharge chamber 63, and a connecting block 621 slidably connected to the inside of the discharge chamber 63. A rectangular brush 623 is fixedly wrapped on one side of the outer side of the connecting block 621, and a pulling block 622 is fixed on one side end of the connecting block 621, and a part of the pulling block 622 extends to the outside through the movable groove 631, and the width and height of the rectangular brush 623 are greater than or equal to the width and height of the discharge chamber 63.

[0029] Specifically, when a large amount of paper scraps are collected in the lower feeding chamber, the paper scraps are pushed out and cleaned through the pushing structure, and the pulling block 622 is grasped to move the force in the movable groove 631, thereby driving the connecting block 621 and the rectangular brush 623 in the discharge chamber 63 to move. The rectangular brush 623 cleans the internal space of the discharge chamber 63 and pushes the paper scraps to the opening position of the lower feeding chamber, thereby completely taking them out and emptying the lower feeding chamber, and the lower feeding chamber can collect materials normally later.

[0030] Working principle:

[0031] In use, stack the cardboard for printing together and place it on the workbench 1. Adjust the paper blocking structure 2 to limit and adjust the cardboard for printing on the workbench 1 so that the cutting position is in the cutting seat 3 and below the paper cutting knife structure 4. Next, grasp the pull rod of the paper cutting knife mechanism and apply a downward force to drive the blade downward to cut the printed cardboard. The blade and the cut shredded paper scraps enter the cutting groove 5;

[0032] As the shredded paper in the cutting groove 5 increases, the user can grasp the handle 611 and pull the movable plate 61 to move. The movable plate 61 is stressed and moves through the moving block 615 in the sliding groove 612. The guide rod 613 extends out of the workbench 1, and the internal spring 614 is compressed and contracted. At this time, the movable plate 61 moves backward to expose the displacement groove, so that the space of the cutting groove expands. The shredded paper inside the displacement groove and the cutting groove falls into the discharge cavity 63 for storage due to the change of space, so that the cutting groove 5 is unblocked, and there is no need for manual time-consuming cleaning of the cutting groove 5, which is relatively time-saving and labor-saving. Release the handle 611, and the spring 614 rebounds to drive the guide rod 613 and the moving block 615 to return to their original positions, so that the movable plate 61 returns to cover the displacement groove;

[0033] When there is a lot of shredded paper collected in the discharge cavity, push the shredded paper out for cleaning through the pushing structure. Grasp the pull block 622 and apply a force to move in the moving groove 631, driving the connecting block 621 and the rectangular brush 623 in the discharge cavity 63 to move. The rectangular brush 623 cleans the internal space of the discharge cavity 63 and pushes the shredded paper to the opening position of the discharge cavity, so as to completely take it out and empty the discharge cavity, and the discharge cavity can receive materials normally in the later stage.
