[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figure 1-Figure 7 As shown, this embodiment proposes a mechanical automatic cutting device, including a cutting centering mechanism 1, a dust removal mechanism 2 and a box body 11. The cutting centering mechanism 1 includes a downward pressure cylinder 12, which is installed inside the box body 11. A downward pressure shaft 121 is installed at the output end of the downward pressure cylinder 12. The bottom of the downward pressure shaft 121 is fixedly connected to a cutting knife 122 by screws. Two symmetrically arranged limit rods 123 are fixedly connected to the inside of the box body 11. The top of the cutting knife 122 is fixedly connected to two symmetrically arranged sliding shafts 124. One side of the sliding shaft 124 is fixedly connected to a connecting plate 125 by screws. The bottom of the connecting plate 125 is fixedly connected to a rack plate 126 by screws. Four symmetrically arranged limit rods 123 are rotatably installed inside the box body 11. The rotating screw 13, the outer circumference of the rotating screw 13 is provided with a sliding block 132, the outer circumference of the rotating screw 13 is fixedly provided with a rotating gear 131, the two rotating gears 131 are meshed with the rack plate 126, the internal sliding assembly of the sliding block 132 is provided with a positioning plate 133, and the interior of the box body 11 is fixedly connected with four symmetrically arranged limit shafts 14. Through the arrangement of the downward pressing cylinder 12, the positioning plate 133 and other structures, after the material position is completed, the downward pressing cylinder 12 is turned on, and the downward pressing cylinder 12 is pressed down while driving the cutting shears 122 to be pressed down for cutting. At the same time, the sliding block 132 drives the positioning block to slide, and slightly adjusts the position of both sides of the material so that it is in the center position of the equipment cutting, thereby improving its cutting accuracy.

[0031] like Figure 1-Figure 7As shown, there are four symmetrically arranged circular holes inside the box body 11, and four rotating screws 13 are rotatably installed inside the four circular holes respectively.

[0032] like Figure 3-Figure 7 As shown, a thread groove is provided inside the sliding block 132 , and the rotating screw 13 is threadedly connected to the inside of the thread groove.

[0033] like Figure 3-Figure 7 As shown, a limiting groove begins to be formed inside the sliding block 132 , and the limiting shaft 14 passes through the limiting groove.

[0034] like Figure 1-Figure 7 As shown, a circular groove begins to be formed inside the limiting rod 123, and the sliding shaft 124 is slidably connected inside the limiting groove.

[0035] like Figure 6 As shown, a square groove is opened inside the sliding block 132, and the positioning plate 133 is slidably connected inside the square groove. Two symmetrically arranged rebound springs 134 are commonly connected between the positioning plate 133 and the inner wall of the square groove.

[0036] When the material is placed on the cutting board, the pressing cylinder 12 is turned on. When the pressing cylinder 12 is pressed down, the pressing shaft 121 is pressed down, and the cutting blade 122 is pressed down to cut. At this time, the pressing shaft 121 drives the sliding shaft 124 to be pressed down, and the sliding shaft 124 is pressed down, and the rack plate 126 is pressed down. When the rack plate 126 is pressed down, the rotating gear 131 is rotated, and the rotating gear 131 rotates to drive the rotating screw 13 to rotate. When the rotating screw 13 rotates, the sliding block 132 is displaced toward the center of the cutting. When the sliding block 132 moves, it drives the positioning plate 133 to move toward the center position of the equipment. A rebound spring 134 is connected between the positioning plate 133 and the sliding plate, which can effectively prevent damage to the material when the material is pushed and positioned. At the same time, the position of both sides of the material can be slightly adjusted so that it is in the center position of the cutting device, thereby improving its cutting accuracy.

[0037] Example 2

[0038] like Figure 1-Figure 4As shown, this embodiment also introduces a mechanical automatic cutting device, which adds the following structure on the basis of the embodiment 1: the dust removal mechanism 2 includes a placement frame 21, the placement frame 21 is fixedly connected to the inside of the box body 11 by screws, the placement frame 21 is fixedly connected to the inside of the porous plate 211, the inside of the box body 11 is equipped with a motor 22, and the inside of the box body 11 is rotatably equipped with two symmetrically arranged rotating shafts 221, the outer circumference of the rotating shaft 221 is fixedly provided with a fan blade 222, and the outer circumference of the two rotating shafts 221 is jointly equipped with a transmission skin Belt 223, one end of one rotating shaft 221 is connected to a coaxially arranged motor 22 through a coupling, and a dust collecting frame 224 is slidingly assembled inside the box body 11. Through the arrangement of the motor 22, the fan blades 222 and other structures, the motor 22 can be turned on while the equipment is cutting. When the motor 22 rotates, the fan blades 222 are driven to rotate. The rotation of the fan blades 222 collects the dust in the cutting process. The dust is filtered when passing through the dust collecting frame 224, so that the dust remains inside the dust collecting frame 224, reducing dust scattering and improving the service life of the equipment.

[0039] like Figure 5-Figure 4 As shown, a groove is provided inside the box body 11, and the dust collecting frame 224 is slidably connected inside the groove.

[0040] The specific implementation principle of this embodiment is as follows: during the cutting process of the equipment, the motor 22 is turned on, and the motor 22 starts to drive one of the rotating shafts 221 to rotate. The rotation of this rotating shaft 221 drives the other rotating shaft 221 to rotate through the transmission belt 223. At the same time as the two rotating shafts 221 rotate, the fan blades 222 are driven to rotate. When the fan blades 222 rotate, the dust generated by the cutting is sucked into the dust collecting frame 224. The dust collecting frame 224 is provided with a mesh to filter and intercept the dust. After the dust collection is completed, it is only necessary to collect the dust. The frame 224 can be taken out to complete cleaning, reduce dust flying, and increase the service life of the equipment. The utility model also has an auxiliary frame 111, a rotating shaft 112, a roller 113 and a two-hand switch 114. The auxiliary frame 111 is arranged on one side of the box body 11, which has a rotating shaft 112. The rotating shaft 112 is provided with a roller 113, which can assist in the transportation of materials. The two-hand switch 114 is arranged on one side of one of the placement frames 21. When the equipment is in use, it is necessary to press the two-hand switch 114 at the same time to start the equipment, thereby improving the safety of use.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
