The other is to use an inclined toothed separating knife, such as the sheet separating device disclosed in the Chinese utility model patent "A Sheet Separating Device" (authorization announcement number: CN216710945U). The distance between the teeth of this separating knife is the same and fixed.

[0038] Sheet 10. Specific embodiments

[0039] The specific embodiments of the present invention are described below through specific examples. Those skilled in the art can easily understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented in other different ways, that is, without departing from the scope disclosed by the present invention, different modifications and changes can be made.

[0040] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the drawings, without special meanings and do not limit the protection scope of the present invention.

[0041] Embodiment: A forced mechanical sheet separating device, as Figures 1 to 11 shown, includes a bracket 1, a main body plate 2, and a lifting drive unit 3 capable of driving the main body plate to lift. A positioning and blowing mechanism 4, a material pressing mechanism 5, and a material separating mechanism 6 are installed on the main body plate 2. The positioning and blowing mechanism 4 includes a positioning drive cylinder 41 and a positioning rod 42. The positioning rod is installed at the power output end of the positioning drive cylinder, and the positioning rod is driven to translate by the positioning drive cylinder;

[0042] Both the material pressing mechanism 5 and the material separating mechanism 6 are installed on the corresponding fine adjustment structure 7, and the material pressing mechanism and the material separating mechanism are driven to lift along the Z direction by the fine adjustment structure;

[0043] The blank holding mechanism 5 includes a blank holding driving cylinder 51, a blank holding seat 52 and a blank holding knife 53. The blank holding seat 52 is installed at the power output end of the blank holding driving cylinder 51, and the blank holding knife is installed on the blank holding seat. The blank holding driving cylinder drives the blank holding seat to move, driving the blank holding knife to translate, pressing and limiting the vertical side of the sheet 10 except the topmost sheet.

[0044] The sheet separating mechanism 6 includes a sheet separating driving cylinder 61, a sheet separating seat 62 and a sheet separating knife 63. The sheet separating seat 62 is installed at the power output end of the sheet separating driving cylinder 61, and the sheet separating knife is installed on the sheet separating seat. The sheet separating driving cylinder drives the sheet separating seat to move, driving the sheet separating knife to move obliquely upward to separate the topmost sheet from the sheets below it.

[0045] In this embodiment, the lifting driving unit 3 is a lifting driving cylinder, and the upper end of the push rod of the lifting driving cylinder is fixedly installed on the main body plate.

[0046] In this embodiment, as Figure 11 shown, in another embodiment of the present invention, the main body plate 2 and the bracket 1 are slidably connected through a first Z-direction slider rail structure 11: The first Z-direction slider rail structure 11 includes a Z-direction slider and a Z-direction rail. A lower nut 12 is fixed to the lower part of the bracket 1, and an upper nut 21 is fixed to the lower part of the main body plate 2 or on the Z-direction slider. Both ends of the first tension spring 13 are respectively installed on the lower nut and the upper nut. Connecting an upper nut and a lower nut to the first tension spring at the same time is beneficial to the quick rebound when the push rod of the lifting driving cylinder retracts, making the positioning rod more quickly in place and the blank holding tighter, with better effect.

[0047] In this embodiment, the sheet separating mechanism is installed on the sheet separating base 64, and the blank holding mechanism is installed on the blank holding base 54;

[0048] Both the blank holding base and the side surface of the main body plate and the sheet separating base and the side surface of the main body plate are slidably connected through a second Z-direction slider rail structure 641;

[0049] As Figure 5 shown, the fine adjustment structure 7 is installed on the main body plate. The fine adjustment structure 7 includes a worm gear 71, a worm 72, a knob 73 and a screw rod 74. The knob is installed at one end of the worm. The worm and the worm gear are meshed. The central hole of the worm gear is provided with internal threads, and the screw rod is threadedly connected to the central hole of the worm gear. One end of the screw rod is installed on the sheet separating base or the blank holding base;

[0050] Rotating the knob drives the worm to rotate. Through the cooperation of the worm gear and the worm, the worm gear is driven to rotate. Then, through the threaded cooperation between the worm gear and the screw rod, the sheet separating base or the blank holding base is driven to move up and down to finely adjust its height.

[0051] The fine-tuning structure of the worm and worm gear combination has a similar function to a micrometer, but has a simpler structure and lower cost, and can achieve the purpose of fine-tuning.

[0052] In this embodiment, the positioning rod is a positioning rod with air holes, and the positioning rod can be externally connected to a gas. It can not only play the role of pressing the material sheet, but also blow air to separate the unseparated part of the topmost material sheet from other material sheets.

[0053] In this embodiment, the material distribution seat and the material distribution base are slidably connected through an X-direction slider rail structure 65. The X-direction slider rail structure 65 includes an X-direction slider 651 and an X-direction rail 652. The root of the material distribution seat is rotatably connected to the X-direction slider through a rotating shaft 66. The middle part of the material distribution seat is connected to the front end of the X-direction slider through a second tension spring 67. The material distribution knife is detachably installed at the end of the material distribution seat.

[0054] In this embodiment, the end of the material distribution knife is triangular with a tip. The tip of the material distribution knife is triangular, which is stronger and not easily broken compared to a sheet-shaped blade, is easier to catch the material, has a better material distribution effect, and will not cause the situation of separating two sheets of material.

[0055] In this embodiment, preferably, the pressing knife and the material distribution knife have similar or the same shape.

[0056] In this embodiment, the pressing seat and the pressing base are also slidably connected through an X-direction slider rail structure 65. It is convenient for the pressing seat to move smoothly along the X direction.

[0057] As Figure 11 shown, in this embodiment, preferably, shoulders 14 are formed on both sides of the upper end of the bracket. A space position avoidance is formed to facilitate the replacement of the pressing knife and the material distribution knife.

[0058] In this embodiment, both the pressing mechanism and the material distribution mechanism are driven by separate cylinders, which can realize different strokes of the pressing knife and the material distribution knife. In this way, it is also applicable to the material distribution of irregular material sheets, further improving the versatility of the device.

[0059] The working principle and process of the present invention:

[0060] As Figure 3 shown, when the lifting drive cylinder is started, the device on the main body plate is driven by the first Z-direction slider rail structure Z1 rail slider to rise to the proper position. Then the positioning drive cylinder drives the positioning rod to extend. At this time, the positioning rod is higher than the material surface, and the lifting drive cylinder is closed. Under the action of gravity, the positioning rod falls on the upper surface of the stack of material sheets;

[0061] As Figure 4 and Figure 5As shown, a fine-tuning structure is used to separately adjust the heights of the material separating knife and the material pressing knife. The height of the material pressing knife is adjusted to be lower than the thickness of a single sheet of the material separating knife by the thickness of one sheet. Then, the material pressing drive cylinder pushes the material pressing knife to closely fit against the vertical side of the lower sheet.

[0062] As Figures 6 to 8 shown, the material separating drive cylinder pushes the X-direction slider to move, the material separating seat rotates clockwise around the rotating shaft, the second tension spring restricts the whole to prevent loosening, and the tip of the material separating knife moves forward and upward to lift the topmost sheet, separating it from the lower sheet. At this time, the positioning drive cylinder pushes out the positioning rod, and the air holes on the positioning rod blow air to completely separate the unseparated part between the topmost sheet and the lower sheet. By repeating this process, the mechanical separation of multiple sheets one by one can be achieved. Figure 10 Figure [X] shows the state after the topmost sheet is lifted, mainly to show the position of the material separating knife at this time. Therefore, the material pressing knife and the positioning rod are not shown in the figure.

[0063] The above are only embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structures made by using the specification and drawings of the present invention, directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
