[0021] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0022] As Figs. 1-3As shown, the anti-rollover plate cutting machine comprises a base 1, a cross rail 2 and a push knife frame 3. One end of the cross rail 2 is vertically fixedly connected to the base 1, and the push knife frame 3 is horizontally slidably installed on the cross rail 2. A push knife 4 that can move up and down is installed below the push knife frame 3. A plurality of upper pulleys 5, side pulleys 6 and bottom pulleys 7 are sequentially arranged from top to bottom along the length direction of the base 1. The axial direction of the upper pulley 5 and the axial direction of the bottom pulley 7 are both perpendicular to the length direction of the base, and the axial direction of the side pulley 6 is perpendicular to the base 1. The side pulley 6 is located between the upper pulley 5 and the bottom pulley 7, and a clamping space for one side of a plate 8 to be inserted is formed between the upper pulley 5, the side pulley 6 and the bottom pulley 7. During cutting, a cushion block (wood board, ceramic tile, etc.) is placed below the plate 8 so that one side of the plate 8 is suspended. During use, the base 1 is placed on one side of the plate 8, and the suspended side of the plate 8 is inserted into the clamping space. The upper pulley 5 acts on the upper surface of one side of the plate, the side pulley 6 acts on the side edge of the plate 8, and the bottom pulley 7 acts on the lower surface of the plate. The push knife 4 is pressed down, and the push knife frame 3 is pushed to move along the cross rail 2, so that the push knife cuts the plate 8. In this way, during the cutting process of pressing down and pushing the push knife 4, once the base 1 is tilted, the bottom pulley 7 can hook the lower surface of the plate 8, so that the base cannot be tilted and cannot damage the plate 8, thereby improving the stability of the base during the cutting process.

[0023] As a preferred embodiment of the above technical solution, the side pulley 6 is connected to the base 1 through a connecting shaft.

[0024] As a preferred embodiment of the above technical solution, a flange 9 is fixed to the lower end of the side pulley 6, and the flange 9 is coaxial with the side pulley 6. The flange 9 can support the lower surface of the plate 8, further preventing the base from tilting during plate cutting.

[0025] As a preferred embodiment of the above technical solution, a side plate 10 is fixedly connected to the outside of the base 1, and the side plate is located below the connection between the cross rail and the base. The side plate 10 connects the bottom pulley 7 through an L-shaped plate below the side plate.

[0026] As a preferred embodiment of the above technical solution, the L-shaped plate comprises a vertical plate 11 and a horizontal plate 12. One end of the horizontal plate 12 is rotatably connected to the bottom pulley 7, and the other end is fixedly connected to the lower end of the vertical plate 11. The vertical plate 11 and the side plate 10 are connected by a plurality of bolts, or are fixed by welding, or are integrally formed.

[0027] As a preferred embodiment of the above technical solution, the vertical plate 11 is located outside the side plate 10. A plurality of threaded holes 13 for the bolts to be screwed into are arranged on the side plate 10, and a plurality of vertical waist holes 14 for the bolts to pass through are arranged on the vertical plate 11. The height of the L-shaped plate can be adjusted through the vertical waist hole 14, so that the user can adjust the height of the bottom pulley 7 installed on the L-shaped plate according to the thickness of the plate, so that the amplitude of the up and down movement of the bottom pulley 7 when hooking the plate is smaller, thereby further improving the stability of the base during the cutting process.

[0028] As the preferred of the above technical solution, the number of the bottom pulley 7 is three.

[0029] As the preferred of the above technical solution, the lower surface of the base 1 is fixedly connected with two parallel clamping plates 15, the clamping plate 15 is fixedly connected with the base 1, and the upper pulley 5 is rotatably installed between the two clamping plates 15. The clamping plate 15, the base 1 and the side plate 10 are integrally formed by aluminum profile, thereby improving the stability of the base.

[0030] As the preferred of the above technical solution, the connection between the base 1 and the cross rail 2 is between one end of the base 1 and the middle of the base 1. Compared with the prior art in which the connection between the base 1 and the cross rail 2 is located in the middle of the base 1, the cross rail 2 is designed to be closer to one end of the base 1. In this way, when the large plate material is just cut, the clamping space can be filled with the plate material to the maximum extent, the suspended part of the base 1 is reduced, and the stability of the pushing sliding process is improved.

[0031] As the preferred of the above technical solution, the push knife frame 3 is provided with an anti-collision block 16 on the side close to the base 1, and the anti-collision block 16 is detachably connected with the push knife frame 3. When the push knife frame 3 moves to the edge of the plate 8, under the action of inertia, excessive force will easily cause the base 1 to tilt, and then cause the push knife frame 3 or the cross rail 2 to knock against the plate 8, resulting in damage to the plate 8. The anti-collision block 16 is made of rubber.

[0032] It is worth mentioning that the push knife, cross rail and other technical features involved in the utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected by using the conventional selection in the field, and should not be regarded as the invention point of the utility model patent. The utility model patent will not be further expanded and described in detail.

[0033] The above detailed the preferred embodiments of the utility model, it should be understood that those skilled in the art can make many modifications and changes without creative labor according to the conception of the utility model, therefore, all the technical solutions obtained by logical analysis, reasoning or limited experiment on the basis of the prior art according to the conception of the utility model should be within the protection scope determined by the claims.
