Description

Technical Field

[0001] The present invention relates to the technical field of post-press equipment in the printing industry, and in particular to a corrugated paper conveying mechanism. Background Art

[0002] Post-press equipment refers to the machinery that further processes semi-finished printed products, including laminating machines and die-cutters. All of these machines require corrugated paper conveying. Currently, most corrugated paper conveying systems on the market use a suction mechanism to suck the paper directly onto the paper delivery roller. This method doesn't provide left-right alignment for the corrugated paper. If the stack of sheets on the corrugated paper is uneven, the face paper will not fit evenly, leading to product quality issues. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention aims to provide a corrugated paper conveying mechanism.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A corrugated paper conveying mechanism, comprising a front supporting paperboard, a rear paperboard, a paper separation suction nozzle mechanism, a paper delivery suction nozzle mechanism, a conveying belt assembly, a paper discharging belt assembly, a front rule 1, a front rule 2, a push rule 1, a push rule 2, a paper receiving roller, a high-speed photoelectric and a supporting paperboard; the front supporting paperboard is arranged in front of the rear paperboard, the front supporting paperboard is L-shaped, and is used to support the front end of the paper stack, the rear paperboard is arranged behind the rear end of the paper stack, and is used to perform rear positioning of the paper; a supporting paperboard is provided below the rear end of the paper, and is used to support the rear end of the paper stack; the paper separation suction nozzle mechanism The nozzle mechanism and the paper delivery suction nozzle mechanism are both arranged below the paper stack. Both the paper separation suction nozzle mechanism and the paper delivery suction nozzle mechanism can move forward and backward, and the suction nozzles of both the paper separation suction nozzle mechanism and the paper delivery suction nozzle mechanism can move up and down. The paper delivery suction nozzle mechanism, the conveyor belt assembly, the paper discharge belt assembly and the paper receiving roller are arranged in sequence from back to front. A high-speed photoelectric device is also provided on the front side of the conveyor belt assembly. When the conveyor belt assembly conveys the paper forward, the high-speed photoelectric device can illuminate the side of the paper, at which time the conveyor belt assembly will stop conveying the paper.

[0006] The front rule 1 is arranged between the paper output belt assembly and the conveyor belt assembly, and the front rule 2 is arranged between the paper output belt assembly and the paper receiving roller; the push rule 1 is used to push the paper delivered by the paper delivery nozzle mechanism to the conveyor belt assembly, and the push rule 2 is used to push the paper transmitted by the conveyor belt assembly toward the paper output belt assembly.

[0007] Furthermore, the belt assembly is an air suction belt assembly that tilts downward from the back to the front.

[0008] Furthermore, the paper separating suction nozzle mechanism and the paper delivering suction nozzle mechanism are arranged in a feeder, and the suction actions of the paper separating suction nozzle mechanism and the paper delivering suction nozzle mechanism are respectively controlled by two different pneumatic valves; in the initial state, the paper separating suction nozzle mechanism and the paper delivering suction nozzle mechanism have the same height, after starting the paper sucking process, the suction nozzle of the paper separating suction nozzle mechanism can be extended upward to the bottom of the paper stack and suck the bottom of the paper under the control of the pneumatic valve, and then the paper separating suction nozzle mechanism and the paper delivering suction nozzle mechanism move backward as a whole to the rear cardboard, at this time, the suction nozzle of the paper separating suction nozzle mechanism releases the paper under the control of the corresponding pneumatic valve, and then descends to its original position, the suction nozzle of the paper delivering suction nozzle mechanism can be extended upward and suck out the bottom of the paper under the control of the corresponding pneumatic valve, and then the paper separating suction nozzle mechanism and the paper delivering suction nozzle mechanism move forward to the position of push gauge one, and the suction nozzle of the paper delivering suction nozzle mechanism releases the paper under the control of the corresponding pneumatic valve, and finally descends to its original position.

[0009] Furthermore, the suction nozzles of the paper separating suction nozzle mechanism and the paper delivering suction nozzle mechanism can extend upward by at least 15 mm when suctioning.

[0010] Furthermore, when the paper separating nozzle mechanism and the paper delivering nozzle mechanism move backward or forward as a whole, the distance moved by the paper separating nozzle mechanism is smaller than the distance moved by the paper delivering nozzle mechanism.

[0011] Furthermore, the paper separating nozzle structure and the paper delivering nozzle mechanism are driven to move back and forth by different crank slider mechanisms respectively, and the crank slider mechanism includes a rotating disk and a crank, and the rotating disk is used to drive the crank to move back and forth by rotating, thereby pushing the connected paper separating nozzle structure or paper delivering nozzle mechanism to move back and forth; the rotating disks of the two crank slider mechanisms are driven to rotate by the same power mechanism, and the rotation radius of the rotating disk corresponding to the paper delivering nozzle mechanism is larger than the rotation radius of the rotating disk corresponding to the paper separating nozzle mechanism.

[0012] Furthermore, the push gauge 1 and the push gauge 2 have the same structure, both including a chain and a sprocket. The sprocket is used to drive the chain to rotate. An iron block serving as a push gauge is installed on the chain. During the rotation of the chain, the iron block can push the paper forward.

[0013] Furthermore, the front rule one and the front rule two can move up and down. When the front end of the paper reaches the front rule one or the front rule two, the front rule one or the front rule two blocks and positions the paper. After the positioning is completed, the front rule one or the front rule two is lifted up so that the paper can continue to be transported forward.

[0014] The beneficial effect of the present invention is that: by using the present invention, the side positioning of the corrugated paper can be effectively performed, eliminating the phenomenon that the corrugated paper is uneven on the left and right after manual papering and the left and right precision is poor after being attached to the face paper, thereby greatly improving the attachment precision of the corrugated paper and the face paper, improving the product yield and reducing costs.

[0019] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0020] This embodiment provides a corrugated paper conveying mechanism, such as Figure 1 As shown, it includes a front supporting paperboard 4, a rear paperboard 3, a paper separation suction nozzle mechanism 1, a paper delivery suction nozzle mechanism 2, a conveying belt assembly 6, a paper discharge belt assembly 10, a front rule 1 8, a front rule 2 9, a push rule 1 5, a push rule 2 7, a paper receiving roller 11, a high-speed photoelectric 12 and a supporting paperboard 13; the front supporting paperboard 4 is arranged in front of the rear paperboard 3, the front supporting paperboard 4 is L-shaped, and is used to support the front end of the paper stack, and the rear paperboard 3 is arranged behind the rear end of the paper stack for rear positioning of the paper; a supporting paperboard 13 is provided below the rear end of the paper to support the rear end of the paper stack; the paper separation suction nozzle mechanism The paper delivery nozzle mechanism 1 and the paper delivery nozzle mechanism 2 are both arranged under the paper stack, and the paper separation nozzle mechanism 1 and the paper delivery nozzle mechanism 2 can both move forward and backward, and the suction nozzles of the paper separation nozzle mechanism 1 and the paper delivery nozzle mechanism 2 can both move up and down; the paper delivery nozzle mechanism 2, the conveying belt assembly 6, the paper discharge belt assembly 10 and the paper receiving roller 11 are arranged in sequence from back to front; a high-speed photoelectric device 12 is also provided on the front side of the conveying belt assembly 6; when the conveying belt assembly 6 conveys the paper forward, the high-speed photoelectric device 12 can just illuminate the position of the side of the paper, and at this time the conveying belt assembly 6 will stop conveying the paper (such as Figure 2 shown);

[0021] The front rule 1 8 is arranged between the paper output belt assembly 10 and the conveyor belt assembly 6, and the front rule 2 9 is arranged between the paper output belt assembly 10 and the paper receiving roller 11; the push rule 1 5 is used to push the paper transferred from the paper delivery nozzle mechanism 2 to the conveyor belt assembly 6, and the push rule 2 7 is used to push the paper transmitted from the conveyor belt assembly 6 toward the paper output belt assembly 10.

[0022] During the operation of the above-mentioned corrugated paper conveying mechanism, the suction nozzle of the paper separating suction nozzle mechanism 1 extends upward to absorb the paper and then moves backward, pulling the absorbed paper to the rear cardboard 3 for rear positioning; then the suction nozzle of the paper delivering suction nozzle mechanism 2 extends upward to absorb the paper, the suction nozzle of the paper separating suction nozzle mechanism 1 releases the paper and retracts downward, and the paper delivering suction nozzle mechanism 2 delivers the paper forward to the push gauge 1 5; the push gauge 1 5 pushes the paper to the conveying belt assembly 6; the conveying belt assembly 6 rotates to deliver the paper to the position of the high-speed photoelectric 12, and the high-speed photoelectric 12 just illuminates the position of the side of the paper. At this time, the conveying belt assembly 6 stops conveying the paper, and the front gauge 1 8 forward positions the paper; at this time, the push gauge 2 7 pushes the paper to the paper output belt assembly 10, and the paper output belt assembly 10 continues to convey the paper forward until it reaches the position of the front gauge 2 9, and the front gauge 2 9 forward positions the paper again, and then the paper output belt assembly 10 continues to deliver the paper to the paper receiving roller 11. Because the side edge of each sheet of paper can be sent to the high-speed photoelectric irradiation position, this can ensure that the side edge of each sheet of paper is transported to the same position, realizing the side positioning of the paper and improving the accuracy of the fit with the surface paper.

[0023] In this embodiment, the belt assembly is a suction belt assembly that tilts downward from the back to the front. The suction belt assembly is used to suck the paper and transport it obliquely forward. When the side of the paper is detected by a high-speed photoelectric sensor, the conveying stops and the paper is released.

[0024] In this embodiment, the paper separation nozzle mechanism 1 and the paper delivery nozzle mechanism 2 are arranged in one feeder, and the suction actions of the paper separation nozzle mechanism 1 and the paper delivery nozzle mechanism 2 are respectively controlled by two different pneumatic valves; Figure 3 As shown, in the initial state, the paper separating suction nozzle mechanism 1 and the paper delivering suction nozzle mechanism 2 have the same height. After the paper sucking process starts, the suction nozzle of the paper separating suction nozzle mechanism 1 can be extended upward to the bottom of the paper stack and suck the bottom of the paper under the control of the pneumatic valve. Then the paper separating suction nozzle mechanism 1 and the paper delivering suction nozzle mechanism 2 move backward as a whole to the rear paper board. At this time, the suction nozzle of the paper separating suction nozzle mechanism 1 releases the paper under the control of the corresponding pneumatic valve, and then descends to its original position. The suction nozzle of the paper delivering suction nozzle mechanism 2 can be extended upward and suck out the bottom of the paper under the control of the corresponding pneumatic valve. Then the paper separating suction nozzle mechanism 1 and the paper delivering suction nozzle mechanism 2 move forward to the position of push gauge one, and the suction nozzle of the paper delivering suction nozzle mechanism 2 releases the paper under the control of the corresponding pneumatic valve, and finally descends to its original position.

[0025] Furthermore, the suction nozzles of the paper separating suction nozzle mechanism and the paper delivering suction nozzle mechanism can extend upward by at least 15 mm when suctioning.

[0026] Furthermore, in this embodiment, when the paper separating nozzle mechanism 1 and the paper delivering nozzle mechanism 2 move backward or forward as a whole, the distance moved by the paper separating nozzle mechanism 1 is smaller than the distance moved by the paper delivering nozzle mechanism 2 .

[0027] More specifically, in this embodiment, if Figure 4 As shown, the paper separating nozzle structure 1 and the paper delivering nozzle mechanism 2 are driven to move forward and backward by different crank slider mechanisms respectively. The crank slider mechanism includes a rotating disk 14 and a crank 15. The rotating disk 14 is used to drive the crank 15 to move forward and backward by rotation, thereby pushing the connected paper separating nozzle structure 1 or the paper delivering nozzle mechanism 2 to move forward and backward; the rotating disks of the two crank slider mechanisms are driven to rotate by the same power mechanism, and the rotation radius of the rotating disk corresponding to the paper delivering nozzle mechanism 2 is larger than the rotation radius of the rotating disk corresponding to the paper separating nozzle mechanism 1.

[0028] Using the same power mechanism to drive both crank slider mechanisms allows for simultaneous forward and backward movement of the paper-separating nozzle mechanism 1 and the paper-delivering nozzle mechanism 2. By using rotating disks with different rotation radii, the crank lengths move at different amplitudes, achieving different amplitudes of movement for the paper-separating nozzle mechanism 1 and the paper-delivering nozzle mechanism 2. In this embodiment, the rotating disk corresponding to the paper-delivering nozzle mechanism 2 has a rotation radius of 60 mm, while the rotating disk corresponding to the paper-separating nozzle mechanism 1 has a rotation radius of 25 mm. When the rotating disk rotates 180°, the paper-separating nozzle mechanism 1 moves 50 mm, and the paper-delivering nozzle mechanism 2 moves 120 mm.

[0029] In this embodiment, the push gauge 1 and the push gauge 2 have the same structure, both including a chain and a sprocket. The sprocket is used to drive the chain to rotate. An iron block serving as a push gauge is installed on the chain. During the rotation of the chain, the iron block can push the paper forward.

[0030] In this embodiment, the front rule one and the front rule two can move up and down. When the front end of the paper reaches the front rule one or the front rule two, the front rule one or the front rule two blocks and positions the paper. After the positioning is completed, the front rule one or the front rule two is lifted up so that the paper can continue to be transported forward.

[0031] It should be noted that the front rule 1 and the front rule 2 are both driven by cylinders to move up and down. Other up and down driving mechanisms can also be used.

[0032] In this embodiment, the chains of the push gauge 1 and the push gauge 2, the conveyor belt assembly and the feeder all have an inclined structure with the front lower and the back higher.

[0033] It should be noted that the distance between the paper discharge belt assembly and the conveyor belt assembly is determined according to the length of the paper.

[0034] Those skilled in the art can make various corresponding changes and modifications based on the above technical solutions and concepts, and all of these changes and modifications should be included in the protection scope of the claims of the present invention.
