DETAILED DESCRIPTION

[0020] The following is combined with Figures 1 to 4 The utility model is described in detail.

[0021] The utility model discloses a cardboard slotting mechanism with a paper scrap storage structure, comprising a conveyor belt 1, the front and rear ends of which are connected to other carton production processes. Under normal circumstances, after the cardboard is pressed, it will be transported to the conveyor belt 1 of the utility model to prepare for slotting. In the utility model, support mechanisms 2 are arranged on both sides of the conveyor belt 1, and the two support mechanisms 2 are symmetrical to each other. A connecting plate 11 and a first lifting motor 12 for driving the connecting plate 11 to rise and fall are arranged below the conveyor belt 1. The support mechanism 2 is provided with a support plate 201. The first upgrading motor drives the conveyor belt 1 to rise, so that the height of the conveyor belt 1 is higher than the support plate 201. After the conveyor belt 1 receives the cardboard, it transports the cardboard to a designated position, the conveyor belt 1 stops rolling, and then the first upgrading motor drives the conveyor belt 1 to descend, so that the top of the conveyor belt 1 is level with the top of the support plate 201, and the two ends of the cardboard are placed on the support plate 201 to prepare for slotting. A receiving groove 21 for accommodating paper scraps is arranged below the support plate 201, a guide plate 22 is arranged between the top of the receiving groove 21 and the support plate 201, and paper outlets 23 are arranged on both sides of the receiving groove 21. A plurality of cutouts 24 are arranged on the support plate 201, including a slotting device 3 arranged above the conveyor belt 1 and the support mechanism 2, the slotting device 3 is provided with a liftable press plate 31, and a retractable cutter 32 is arranged at the bottom of the press plate 31, and the cutter 32 can cooperate with the cutout 24 to slot and cut the corners of the cardboard. When slotting, the press plate 31 first presses the cardboard, and then the cutter 32 extends to cut the cardboard into slots, and the cut paper scraps fall onto the guide plate 22 through the cutout 24, and finally fall into the receiving groove 21. The cut paper scraps can be cleaned out from the paper outlet 23 after being accumulated, reducing the degree of air pollution caused by the flying dust generated by the paper scraps, improving the air quality of the equipment working environment, and having high environmental protection performance. The utility model fixes the paperboard by cooperating with the press plate 31 and the support plate 201, so that the paperboard can be prevented from moving when the paperboard is cut, and the cutting and grooving speed is fast and the precision is high.

[0022] The slotting device 3 is provided with a fixing frame 33, and a transmission device 4 is provided on the fixing frame 33 to drive the plate pressing device 31 to move horizontally. The position of the plate pressing device 31 can be adjusted according to the size of the paperboard, the slotting position, etc., so as to facilitate positioning, cutting and slotting of various paperboards.

[0023] The transmission device 4 is provided with a transmission motor 41, a first transmission wheel 42, a second transmission wheel 43, a transmission belt 44, and a connection block 45 fixedly connected to the transmission belt 44 in sequence. The first transmission wheel 42 is connected to the second transmission wheel 43 through the transmission belt 44, and the first transmission wheel 42 is fixedly connected to the rotating shaft of the transmission motor 41. The transmission motor 41 can drive the connection block 45 to move, thereby driving the platen device 31 to move.

[0024] Specifically, the slotting device 3 is provided with a lifting rod 34 movably connected to the connecting block 45, a second lifting motor 35 is provided at one end of the lifting rod 34, and the plate presser 31 is fixedly provided at the other end of the lifting rod 34. The transmission device 4 drives the lifting rod 34 to drive the plate presser 31 to move together, and adjusts the position of the plate presser 31. When slotting, the second lifting motor 35 drives the lifting rod 34 to descend, so that the plate presser 31 presses the cardboard on the support plate 201 to fix the cardboard. After the slotting is completed, the lifting rod 34 is reset, and the first lifting motor 12 drives the conveyor belt 1 to rise, so that the cardboard leaves the support plate 201, and then the conveyor belt 1 rolls to send the slotted cardboard to the next cardboard production process, and the cutting and slotting is stable and efficient.

[0025] One end of the plate pressing device 31 is provided with a cylinder 36 for driving the cutter 32 to extend and retract. The blade of the cutter 32 faces downward. During the process of cutting and slotting the cardboard, the cylinder 36 drives the cutter 32 to press down, and then resets, and repeats this process 3 to 5 times in sequence. The speed and depth of each press down gradually increase, and the cardboard is finally completely cut off. The slotting process of the cutter 32 lasts for about 1 second, and the slotting quality is stable.

[0026] The side of the plate presser 31 is provided with an air inlet 311, and the bottom of the plate presser 31 is provided with an air outlet 312 which is interconnected with the air inlet 311. The air inlet 311 is externally connected with a blowing air pipe, and the cutter 32 repeatedly cuts the cardboard to make grooves, and the gas is blown toward the air outlet 312 through the air inlet 311, exerting a thrust on the cardboard pre-cut by the cutter 32, so that the cut paper scraps can stably enter the cutout portion 24, so that the accommodating groove 21 can accommodate the paper scraps.

[0027] More specifically, the cutter 32 is U-shaped. The curved end of the U-shaped cutter 32 faces the conveyor belt 1, and a gap is provided in the middle of the corrugated cardboard. When the corrugated cardboard is cut, the air outlet 312 blows air toward the cardboard scraps. The U-shaped cutter 32 can further block the scraps and prevent the scraps from flying into the gap of the corrugated cardboard and affecting the neatness of the cardboard.

[0028] The side wall of the receiving groove 21 is provided with a guide window 25, and a push plate 26 is provided in the receiving groove 21. The push plate 26 is provided with a hand-pull plate 261 that passes through the guide window 25 and extends outward. When the paper scraps in the receiving groove 21 are accumulated to a certain extent, the worker can pull the hand-pull plate 261 to push the push plate 26, so that the push plate 26 pushes the paper scraps in the receiving groove 21 out of the paper outlet 23, which is convenient for the worker to clean up the paper scraps. The structure is simple and easy to use.

[0029] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
