[0032] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0033] like Figure 1-5 As shown, a corrugated cardboard flattening device comprises a flattening platform 1, a translation frame 2 is fixedly connected to the upper side of the flattening platform 1, the translation frame 2 is assembled and connected to a flattening mechanism 3, and a positioning device 4 is provided on one side of the translation frame 2;

[0034] The flattening mechanism 3 includes a translation block 31, a telescopic cylinder 32 is assembled and connected below the translation block 31, a hinged plate 33 is assembled and connected below the telescopic cylinder 32, and a flattening member 34 is hinged below the hinged plate 33;

[0035] A roller 341 is rotatably connected to the middle of the lower portion of the flattening member 34 . The lower side of the roller 341 is located below the flattening member 34 . Both sides of the roller 341 of the flattening member 34 are inclined obliquely upward.

[0036] According to the technical solution of this embodiment, the pressing platform 1 is used to place the corrugated cardboard, the translation frame 2 is used to drive the flattening mechanism 3 to move, the flattening mechanism 3 flattens the corrugated cardboard, the positioning device 4 is used to position the corrugated cardboard to prevent the flattening mechanism 3 from moving during the flattening process of the corrugated cardboard, thereby affecting the flattening effect, and the telescopic cylinder 32 is used to control the flattening member 34 to move downward. When the flattening member 34 moves downward, the roller 341 first contacts the corrugated cardboard, and the translation block 31 moves along the translation frame 2 to flatten the corrugated cardboard. Because both sides of the flattening member 34 It is inclined upward, so the center of gravity of the flattening piece 34 is located on the upper part of the roller 341. When the flattening piece 34 is moved, the flattening piece 34 will rotate, so that the inclined surface of the flattening piece 34 contacts the corrugated cardboard. There is rolling friction between the roller 341 and the corrugated cardboard. Therefore, when the translation frame 2 drives the translation block 31 to move, the driving force required by the translation frame 2 to move the flattening piece 34 can be reduced. The two sides of the flattening piece 34 are inclined upward, so when the flattening piece 34 moves, the force on the flattening piece 34 changes, and the inclined surface of the flattening piece 34 contacts the corrugated cardboard to flatten the corrugated cardboard.

[0037] Reference Figure 3 The translation frame 2 includes four pillars 21, which are located at the four corners of the pressure platform 1. A connecting bar 22 is fixedly connected to the top of two pillars 21 on one side, and a sliding rod 23 and a screw 24 are provided between the two connecting bars 22. The connecting bar 22 is assembled and connected to a motor 241 that is transmission-connected to the end of the screw 24. The translation block 31 is threadedly connected to the screw 24 and slidably connected to the sliding rod 23.

[0038] In this embodiment, when the lead screw 24 rotates, the lead screw 24 drives the translation block 31 to move, and the translation block 31 drives the flattening member 34 to move to flatten the corrugated cardboard. The slide bar 23 is used to ensure the horizontal arrangement of the translation block 31.

[0039] Reference Figure 3 : There are two slide bars 23, and the two slide bars 23 are located on both sides above the pressing platform 1.

[0040] Reference Figure 5 The positioning device 4 includes a positioning block 41, both ends of which are slidably connected to the sliding rod 23, a rotating shaft 42 is rotatably connected below the positioning block 41, both ends of the rotating shaft 42 are transmission-connected with vertically arranged connecting rods 43, the lower end of the connecting rod 43 is provided with a thread, the thread at the lower end of the connecting rod 43 is spirally connected to a threaded sleeve 44, and the lower ends of the two threaded sleeves 44 are fixedly connected to positioning plates 45.

[0041] In this embodiment, because the positioning block 41 is slidably connected to the slide rod 23, the positioning block 41 can move according to the size of the corrugated cardboard to position the end of the corrugated cardboard. When the rotating shaft 42 is rotated, the connecting rod 43 rotates. When the connecting rod 43 rotates, the threaded sleeve 44 and the connecting rod 43 move up and down, so that when the rotating shaft 42 is rotated, the positioning plate 45 moves up and down.

[0042] Reference Figure 5 The connecting rod 43 is rotatably connected below the positioning block 41, the two ends of the rotating shaft 42 are assembled and connected with the first bevel gear 51, the upper part of the connecting rod 43 is assembled and connected with the second bevel gear 52, and the first bevel gear 51 and the second bevel gear 52 are meshed and transmission connected.

[0043] In this embodiment, the lateral rotation is converted into vertical rotation by the meshing of the first bevel gear 51 and the second bevel gear 52. The second bevel gear 52 is located on the inner side of the first bevel gear 51, so the rotation directions of the connecting rod 43 are opposite, and the spiral directions of the threads at the lower ends of the two connecting rods 43 are opposite. Therefore, when the rotating shaft 42 is rotated, the two threaded sleeves 44 move up or down at the same time, and the positioning plate 45 is moved up and down by rotating the rotating shaft 42.

[0044] Reference Figure 5 : The end of the rotating shaft 42 is fixedly connected with a rotating handle 6.

[0045] In this embodiment, the rotating handle 6 is used to drive the rotating shaft 42 to rotate, which has a labor-saving effect.

[0046] Reference Figure 4 : Counterweight blocks 342 are provided on both sides of the flattening member 34, and the plane on the lower side of the counterweight blocks 342 is located in the same plane as the plane below the flattening member 34.

[0047] In this embodiment, the counterweight block 342 is used to ensure that the gravity of the flattening member 34 is located above the roller 341, so that the flattening member 34 is easily offset, so that the inclined surface of the flattening member 34 contacts the corrugated cardboard to flatten the corrugated cardboard.

[0048] Working principle: the corrugated cardboard is first placed on the pressing platform 1, and one end of the corrugated cardboard is placed on the left side of the pressing platform 1, and then the positioning mechanism 4 is moved to the left end of the corrugated cardboard, and the positioning plate 45 is moved downward by rotating the rotating handle 6 to tightly position the corrugated cardboard. After the positioning of the corrugated cardboard is completed, the lead screw 24 is controlled by the motor to rotate, so that the flattening piece 34 moves from the left end to the right end, and the translation block 31 returns when it is close to the positioning block 41, and the motor 241 reverses. The forward and reverse rotation of the motor 241 is controlled by the sensor. When the sensor of the positioning block 41 senses that the translation block 31 is approaching, a signal is sent to the motor 241, so that the motor 241 reverses; the flattening piece 34 moves in the opposite direction, and the flattening piece 34 is hinged to the hinged plate 33, so when the flattening piece 34 is unbalanced, the flattening piece 34 rotates, and the inclined surface of the flattening piece 34 contacts the corrugated cardboard to flatten the corrugated cardboard.

[0049] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0050] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
