Description

Technical Field

[0001] The utility model relates to the technical field of paper product production equipment, in particular to a cutting device for paper product production. Background Art

[0002] Paper products are typically unprocessed or minimally processed. They undergo a series of processes, including designing, cutting, folding, and printing, before becoming finished products. For example, printing paper is not produced in stacks, but rather rolled into rolls for easy transportation and subsequent processing. Paper manufacturers first split the rolls into larger sheets, depending on the intended use, and then cut the sheets into the desired size.

[0003] Cutting paper requires a paper trimmer. Conventional paper trimmers typically consist of a knife, a pusher, and a presser. Operators use the pusher to align the paper, the presser to hold the top of the paper down, and the knife to cut from top to bottom. This poses a risk. Utility Model Content

[0029] Example 1:

[0030] See also Figure 1-5 The present invention describes the above technical solution in detail through the following embodiments:

[0031] A cutting device for paper product production, comprising:

[0032] The cutting assembly 1 includes a cutting table 11, a cutting frame 12 is fixedly installed on the top front of the cutting table 11 by bolts, a cutter 14 is slidably installed in the cutting frame 12, a pushing assembly 2 is provided on the top surface of the cutting table 11 and behind the cutting frame 12, and an alignment assembly 3 is provided on the front side of the cutting assembly 1.

[0033] The cutter 14 is used for cutting paper products.

[0034] A first cylinder 13 and a second cylinder 15 are provided on the top of the cutting frame 12. The piston rod of the first cylinder 13 passes through the cutting frame 12 and is fixedly connected to the cutter 14 by bolts. The piston rod of the second cylinder 15 passes through the cutting frame 12 and is fixedly connected to the pressing plate 16 by bolts.

[0035] When the first cylinder 13 is working, it can drive the cutter 14 to move in the vertical direction. When the second cylinder 15 is working, it can drive the pressing plate 16 to move in the vertical direction.

[0036] The pressing plate 16 can press the paper product to prevent the paper product from moving when the cutter 14 cuts.

[0037] The pusher assembly 2 includes a slide frame 21, which is slidably connected to the cutting table 11. A push plate 23 is fixed to the front of the slide frame 21 and located on the top of the cutting table 11 by screws. The slide frame 21 is connected to a drive device, which is used to drive the slide frame 21 to slide along the cutting table 11, pushing the paper product toward the cutter 14.

[0038] When the sliding frame 21 moves, it can drive the push plate 23 to move along the top surface of the cutting table 11. When the paper product is placed on the top surface of the cutting table 11 and the push plate 23 moves toward the cutter 14, it can drive the paper product to move toward the cutter 14.

[0039] The pusher assembly 2 includes a baffle 22 , which is fixed to the left and right sides of the top surface of the cutting table 11 by screws. A through hole is provided at the bottom of the baffle 22 , and the sliding frame 21 can slide along the through hole.

[0040] The baffle 22 can limit the movement of the paper product to both sides, thereby preventing the paper product from sliding off the top surface of the cutting table 11 when moving toward the cutter 14 .

[0041] The driving device includes a first screw 24 , which is rotatably mounted at the center of the bottom surface of the cutting table 11 . The first screw 24 is threadedly connected to the sliding frame 21 , and a first motor 25 is provided at the end of the first screw 24 .

[0042] The first motor 25 is a servo motor and is fixedly mounted on the bottom surface of the cutting table 11 by bolts. When the first motor 25 is working, it can drive the first screw 24 to rotate, thereby driving the threaded sliding frame 21 to move, and then driving the push plate 23 to move.

[0043] The alignment component 3 includes a loading platform 31, and two paper pushing racks 36 are slidably installed on the top surface of the loading platform 31. Each paper pushing rack 36 passes through the loading platform 31 downward and is fixed with a second slider 35 by screws. The second slider 35 is connected to a second drive component, and the second drive component is used to drive the two paper pushing racks 36 to move horizontally at the same time.

[0044] The sides of the paper pusher 36 are against each other and the end faces are flush. When the paper pusher 36 moves toward the cutter 14, it can push the paper products toward the push plate 23, and cooperate with the push plate 23 to align the paper products.

[0045] A guide groove 32 is formed on the top surface of the loading platform 31 . A receiving groove 33 is formed on the outer side of one end of the guide groove 32 away from the cutting platform 11 . The paper pusher 36 can slide along the guide groove 32 .

[0046] The guide groove 32 is used to limit the moving direction of the paper pushing rack 36 .

[0047] The second driving assembly includes a second lead screw 34 , which is rotatably mounted directly below the guide slot 32 . The axis of the second lead screw 34 is parallel to the axis of the guide slot 32 , and the second slider 35 is threadedly connected to the second lead screw 34 .

[0048] When the second lead screw 34 rotates, it can drive the second slider 35 to rotate, and then drive the paper pusher 36 to rotate. When the paper pusher 36 abuts against the side surfaces of the receiving groove 33 and the guide groove 32, the paper pusher 36 cannot rotate, and thus the second slider 35 cannot rotate. At this time, the second lead screw 34 continues to rotate, and the second slider 35 will move along the axis of the second lead screw 34, so that the paper pusher 36 will move along the axis of the guide groove 32.

[0049] The head of the second lead screw 34 passes through the loading platform 31 and is connected to the second motor 38 through the gear box 37 .

[0050] Two large gears 371 are rotatably mounted in the gear box 37 . Each of the large gears 371 is meshed with a small gear 372 . The two small gears 372 are meshed with each other, and one of the small gears 372 is engaged with the output shaft of the second motor 38 .

[0051] The second motor 38 is a servo motor. When the second motor 38 is working, it can drive one of the small gears 372 to rotate, thereby driving the meshing large gear 371 and the other small gear 372 to rotate, and then driving the other large gear 371 to rotate. At this time, the rotation directions of the two large gears 371 are opposite.

[0052] The second lead screw 34 is engaged with the two large gears 371 , so that when the second motor 38 is working, it can drive the two second lead screws 34 to rotate in opposite directions at the same time.

[0053] When the operator of this embodiment uses the device, he places paper products on the cutting table 11 and stacks them neatly, controls the first motor 25 to work, and rotates the first lead screw 24, thereby driving the threaded sliding frame 21 to move, and further driving the push plate 23 to move.

[0054] When the push plate 23 moves toward the cutter 14 , it can drive the paper product to move toward the cutter 14 .

[0055] When the paper product exceeds the distance of the cutter 14 and reaches the cutting length, the first motor 25 stops working.

[0056] The second motor 38 is controlled to work, and the two second lead screws 34 are driven to rotate in opposite directions at the same time through the gear box 37. When the second lead screw 34 rotates, the second slider 35 can be driven to rotate, and then the paper pusher 36 is driven to rotate. When the paper pusher 36 abuts against the side surfaces of the receiving groove 33 and the guide groove 32, the paper pusher 36 cannot rotate, and thus the second slider 35 cannot rotate. At this time, the second lead screw 34 continues to rotate, and the second slider 35 will move along the axis of the second lead screw 34, so that the paper pusher 36 will move along the axis of the guide groove 32.

[0057] When the paper pusher 36 moves toward the cutter 14 , it can push the paper products toward the push plate 23 , and cooperate with the push plate 23 to align the paper products.

[0058] After the paper products are aligned, the second motor 38 is controlled to stop working, and the second cylinder 15 is controlled to work to drive the pressing plate 16 to descend and press the paper products.

[0059] The second motor 38 is controlled to operate again, driving the second lead screw 34 to reverse, driving the paper pusher 36 away from the cutter 14. When the paper pusher 36 moves to the receiving slot 33, it is no longer blocked by the guide slot 32, and the paper pusher 36 and the second slider 35 rotate toward the receiving slot 33 until the paper pusher 36 is flush with the loading platform 31, at which point the second motor 38 is stopped.

[0060] At this time, the first cylinder 13 is controlled to work, driving the cutter 14 to move downward to cut the paper product. After cutting, the first cylinder 13 is controlled to work, driving the cutter 14 to move upward to cut the paper product. At the same time, the second cylinder 15 is controlled to work, driving the pressing plate 16 away from the paper product.

[0061] Remove the cut paper.

[0062] Repeat the above steps to complete the cutting of the paper product.
