[0021] The following will be combined with the drawings in 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.

[0022] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the present invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0023] like Figure 1 As shown, the embodiment of the present invention includes a frame 1 for placing cardboards, and the frame 1 includes a placement table 11 for placing cardboards; and a mounting bracket 12 fixedly connecting the lifting component 2 and the clamping component 4.

[0024] Specifically, in this embodiment, the frame 1 is spliced ​​by slotted aluminum, and the cardboard is manually placed on the placement table 11 to facilitate the lifting component 2 and the clamping component 4 to transport and cut the cardboard. Secondly, the left side of the mounting bracket 12 is fixedly connected to the placement table 11, the middle is fixedly connected to the lifting component 2, and the right side is fixedly connected to the clamping component 4, so that the processing path of the cardboard is from left to right.

[0025] Furthermore, this embodiment also includes: a lifting assembly 2 for lifting the cardboard, which slides relative to the frame 1 along a horizontal plane; a clamping assembly 4 arranged on the frame 1, which includes a grabbing claw 44 for clamping the cardboard, and the grabbing claw 44 moves relative to the lifting assembly 2 and the frame 1; and a cutting assembly 6 for cutting the cardboard, and the grabbing claw 44 can drive the cardboard and the lifting assembly 2 to move relative to the cutting assembly 6.

[0026] Specifically, the lifting assembly 2 can lift the cardboard in the placement table 11 to a certain height to separate it from other cardboards. In addition, the lifting assembly 2 can slide relative to the mounting bracket 12, so that the lifted cardboard can slide relative to the mounting bracket 12. Secondly, the clamping assembly 4 is fixedly connected to the right side of the mounting bracket 12. The grabbing claw 44 can approach the lifting assembly 2 through a power part such as a guide rail or a cylinder, thereby clamping the lifted cardboard. Then, the grabbing claw 44 can drive the lifted cardboard and the lifting assembly 2 to move rightward relative to the mounting bracket 12. The lifted cardboard is then moved to the top of the cutting component 6, where the distance that the grabbing claw 44 moves to the right depends on the distance between the rightmost side of the cardboard and the cutting surface of the cutting component 6, which is the cardboard size required for production. Therefore, the size of the cut cardboard can be adjusted by adjusting the movement distance of the grabbing claw 44. After the lifting component 2 lifts the cardboard, the clamping component 4 automatically approaches the lifting component 2 to clamp the lifted cardboard and moves it to the cutting component 6, thereby realizing automatic cutting of the cardboard, thereby improving the cutting efficiency of cardboards of different sizes.

[0027] like Figure 2 As shown, the clamping assembly 4 also includes: a movable guide rail 42 arranged on the frame 1, the length direction of the movable guide rail 42 is the movement direction of the grabbing claw 44; and a movable bracket 41 arranged on the movable guide rail 42, the grabbing claw 44 is arranged on the movable bracket 41, and the movable bracket 41 drives the grabbing claw 44 along the movable guide rail 42 under the push of the movable cylinder 43 to approach or move away from the lifting assembly 2.

[0028] Specifically, the telescopic direction of the moving cylinder 43 is the same as the length direction of the moving guide rail 42, so that it can push the moving bracket 41 to move along the moving guide rail 42, and then drive the grabbing claw 44 to move along the moving guide rail 42, so that the grabbing claw 44 can approach the lifting component 2 to clamp the lifted cardboard, and move away from the placement table 11 to place the clamped cardboard on the cutting track of the cutting component 6, so that after the lifting component 2 automatically lifts the cardboard, the clamping component 4 can automatically move the lifted cardboard to the area to be cut. Secondly, the stroke of the moving cylinder 43 is the stroke of the grabbing claw 44 to ensure that it can contact and clamp the lifted cardboard. The movement trajectory of the moving cylinder 43 is also the movement trajectory of the lifted cardboard, so that the moving cylinder 43 can adjust its own proximity switch in time to adjust the movement distance of the lifted cardboard, and then determine its cutting size, thereby improving the flexibility of cutting cardboard.

[0029] Furthermore, the clamping assembly 4 also includes a clamping claw cylinder 45 that drives the grabbing claw 44 to clamp the cardboard. The grabbing claw 44 is connected to the movable end of the clamping claw cylinder 45. The grabbing claw 44 adjusts its own thickness to change the height of its grabbing surface in contact with the cardboard. The lifting surface of the lifting assembly 2 in contact with the cardboard can be coplanar with the grabbing surface.

[0030] Specifically, the movement of the clamping jaws 44 is an opening and closing movement, so that the grabbing jaws 44 are separated from or contacted with the lifted cardboard for clamping. When the type of the clamping jaws 45 is determined, the opening and closing stroke of the grabbing jaws 44 is determined, which only needs to be greater than the thickness of the cardboard. Secondly, the clamping surface of the relative movement of the grabbing jaws 44 is adjusted according to the height of the top surface of the lifted cardboard, so that the clamping surfaces of the grabbing jaws 44 after contacting the cardboard are respectively coplanar with the top and bottom surfaces of the cardboard, so that after the grabbing jaws 44 clamp the cardboard, the cardboard does not bend relative to the lifting component 2, thereby affecting the flatness of the cardboard.

[0031] like Figure 3 As shown, the lifting assembly 2 includes: a lifting cylinder 21 arranged on the frame 1, and the movement direction of the telescopic end of the lifting cylinder 21 is perpendicular to the cardboard; and a vacuum suction cup 22 arranged at the telescopic end of the lifting cylinder 21, and the lifting cylinder 21 can drive the vacuum suction cup 22 and then drive the cardboard to move vertically.

[0032] Specifically, the lifting assembly 2 is fixedly connected to the mounting bracket 12 and is directly above the placement table 11, so that when the lifting cylinder 21 drives the vacuum suction cup 22 to move downward, it can contact the cardboard in the placement table 11, and thus the vacuum suction cup 22 is fixedly connected to the cardboard through vacuum. In this embodiment, three vacuum suction cups 22 are provided, thereby increasing the force exerted on the cardboard, thereby enhancing the stability between the cardboard and the vacuum suction cup 22. After the vacuum suction cup 22 is fixedly connected to the cardboard, the lifting cylinder 21 moves upward perpendicular to the cardboard, so that the cardboard in contact with the vacuum suction cup 22 is separated parallel to other cardboards, which is convenient for subsequent grabbing claws 44 to grab, and prevents the lifted cardboard from escaping from the opening and closing area of ​​the grabbing claws 44.

[0033] Furthermore, it also includes a slide rail 3, the length direction of which is the movement direction of the lifting cylinder 21 relative to the frame 1. The clamping component 4 drives the lifting cylinder 21 and then drives the cardboard to move along the slide rail 3 relative to the cutting component 6.

[0034] Specifically, the slide rail 3 is fixedly connected to the mounting bracket 12, and the mounting surface of the slide rail 3 is parallel to the cardboard, so that when the lifting cylinder 21 moves along the slide rail 3, the lifting height of the side of the cardboard close to the clamping component 4 remains unchanged, so that the grabbing claw 44 can clamp this side and drive the cardboard to move along the slide rail 3, and then drive the cardboard to be placed directly above the cutting component 6, wherein the length direction of the slide rail 3 is also perpendicular to the rightmost side of the cardboard, so that during the movement of the cardboard, its rightmost side is always parallel to the cutting surface of the cutting component 6, thereby ensuring the cutting effect of the cardboard.

[0035] like Figure 4As shown, the cutting assembly 6 includes: a cutting guide rail 61 arranged on the frame 1, the mounting surface of the cutting guide rail 61 is parallel to the cardboard, and the length direction of the cutting guide rail 61 is perpendicular to the movement direction of the grabbing jaw 44; and a cutting tool 62 that moves along the length direction of the cutting guide rail 61, the cutting surface of the cutting tool 62 can intersect with the cardboard, and the grabbing jaw 44 drives the cardboard to move relative to the cutting tool 62.

[0036] Specifically, the cutting tool 62 moves along the cutting guide 61 to cut the cardboard. The cutting surface of the cutting tool 62 is the cutting surface. When the cutting tool 62 moves along the cutting guide 61, the height difference between the cutting tool 62 and the cardboard remains unchanged, so that the cutting tool 62 can always contact the cardboard when cutting the cardboard, thereby ensuring the continuity of cutting. Secondly, the grabbing jaw 44 drives the cardboard to move relative to the cutting tool 62 until it intersects with the cutting surface of the cutting tool 62. The cutting tool 62 moves from left to right to cut the cardboard to obtain cardboard that meets the size; secondly, the movement trajectory of the cutting tool 62 is always perpendicular to the movement trajectory of the grabbing jaw 44, so that the two side surfaces of the cut cardboard are parallel, ensuring the cutting quality.

[0037] like Figure 5 As shown, this embodiment also includes a conveying assembly 5, which includes: a conveyor belt 51 arranged on the frame 1, and the conveying direction of the conveyor belt 51 is the movement direction of the cutting assembly 6 for cutting the cardboard; a clamping member 52 arranged on the conveyor belt 51, and the clamping member 52 is tangent to the conveyor belt 51; and a straightening cylinder 53 arranged on one side of the conveyor belt 51, the telescopic end surface of the straightening cylinder 53 is parallel to the side surface of the conveyor belt 51, and the distance between the telescopic end surface of the straightening cylinder 53 and the side surface of the conveyor belt 51 is the width of the cut cardboard.

[0038] Specifically, the grabbing jaws 44 place the cut cardboard between the two conveyor belts 51. When the grabbing jaws 44 separate from the cut cardboard, the cardboard falls onto the conveyor belt 51 and moves toward the discharge port under the drive of the conveyor belt 51. One side of the cardboard is limited by the protrusion on one side of the conveyor belt 51, and the other side is limited by the straightening cylinder 53, so that the positions of the two sides of the cardboard relative to the two sides of the conveyor belt 51 remain unchanged during the conveying process, thereby ensuring the position accuracy of the cardboard when it exits the discharge port; secondly, the clamping member 52 consists of a clamping rod rotatably connected to the frame 1 and a clamping wheel rotatably connected to one end of the clamping rod. The side of the clamping wheel is tangent to the top surface of the cardboard. When the cardboard moves, the clamping wheel moves, so that the clamping wheel can apply pressure to the conveyor belt 51 on the cardboard being conveyed, ensuring that the position of the cardboard relative to the conveyor belt 51 does not change.

[0039] Secondly, the cut cardboard is limited by the telescopic end face of the straightening cylinder 53 and one side face of the conveyor belt 51 so that its width is the distance between the two. The straightening cylinder 53 can adjust the distance between the end face and the conveyor belt 51 according to the different widths of the cut cardboard, so as to improve the adaptability of the conveyor belt 51 to the size of the conveyed cardboard.

[0040] Furthermore, the conveyor belt 51 is provided at both ends of the clamping assembly 4 , and the movement trajectory of the grabbing jaw 44 does not intersect with the conveyor belt 51 .

[0041] Specifically, the conveyor belt 51 is divided into two sections and operates independently. A grabbing claw 44 is provided between the two sections, so that the moving cylinder 43 drives the grabbing claw 44 to move without interfering with the conveyor belt 51. When the grabbing claw 44 moves the cut cardboard to the top of the two sections of the conveyor belt 51, the grabbing claw 44 opens and the cardboard can fall onto the top of the conveyor belt 51 and be transported out, realizing automatic loading, automatic cutting and automatic discharging of the cardboard, further improving the degree of automation of the embodiment.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
