[0002] Current plate cutting machines usually manually stabilize the plates in position for cutting, but their precision is poor. During cutting, the force exerted by the cutter on the plate is large, which inevitably causes displacement of the plate, resulting in reduced cutting precision. In addition, existing plate cutting machines have low cutting efficiency. Summary of the invention

[0003] In order to solve the above technical problems, an object of the present invention is to provide a plate cutting machine with high cutting efficiency.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a plate cutting machine, comprising a cutting table, a cutting mechanism and a first driving member, the cutting table is horizontally arranged along the front-to-back direction, and its upper end is used to place the plate, the cutting part of the cutting mechanism is suspended above the cutting table, the first driving member is used to drive the cutting mechanism to move along the front-to-back direction, and the cutting mechanism is used to cut the plate.

[0005] The beneficial effect of the above technical solution is that: it has a simple structure, and the first driving member drives the cutting mechanism to move along the front-rear direction on the cutting table, so that the cutting part of the cutting mechanism can move automatically to cut the plate.

[0006] The cutting mechanism described in the above technical solution includes a two-dimensional moving mechanism and a knife seat, wherein the two-dimensional moving mechanism is installed above the cutting table, and the knife seat is installed at the driving end of the two-dimensional moving mechanism, and the knife seat is used to detachably install the cutter, and the blade of the cutter faces downward, and the two-dimensional moving mechanism is transmission-connected to the first driving member, and the first driving member is used to drive the two-dimensional moving mechanism to move in the front-to-back direction, and the two-dimensional moving mechanism is used to drive the knife seat to drive the cutter to move in the up-down direction and / or left-right direction, and the knife seat and the cutter constitute the cutting part of the cutting mechanism.

[0007] The beneficial effect of the above technical solution is that the two-dimensional moving mechanism can cooperate with the first driving member to drive the knife holder to drive the cutter to move three-dimensionally so as to cut the plate more flexibly and efficiently. For example, the two-dimensional moving mechanism can drive the cutter to move in the left and right directions to cut the plate.

[0008] The two-dimensional moving mechanism in the above technical scheme includes a transverse moving component, a longitudinal moving component and two support seats. The transverse moving component is horizontally arranged above the cutting table in the left-right direction, and its two ends are slidably connected to the two sides of the cutting table through one of the support seats respectively. The support seat slides in the front-to-back direction on the cutting table under the action of external force.

[0017] The beneficial effect of the above technical solution is that the second driving member can drive the tool holder to rotate to any of the placement positions where no cutter is placed and is located directly below the tool holder. At this time, the tool holder can be driven by the longitudinal driving member to move downward to place the cutter on the corresponding placement position, and then move upward to reset to achieve the action of removing the cutter. The second driving member then drives the tool holder to rotate to any of the placement positions where a cutter is placed and is located directly below the tool holder. At this time, the tool holder can be driven by the longitudinal driving member again to move downward to be detachably connected with the cutter on the corresponding placement position to achieve automatic installation of the cutter.

[0018] In the above technical solution, a plurality of pressure plate assemblies are respectively provided in the middle part and any one side of the cutting table.
