Description

Technical Field

[0001] This utility model relates to the field of printing plate production technology, and in particular to a double-cutting and center-cutting integrated machine. Background Technology

[0002] In the printing plate production process, as production technology becomes more mature, the control of production costs and other aspects becomes more refined. In the production process, small-sized plates are produced using wide-format plates and cut in the middle. The middle cutting technology currently used is achieved by a double-cutting machine, a middle-cutting machine, and a linkage system. The principle is as follows: the double-cutting machine is to enable the middle-cutting machine to cut accurately according to the preset size, ensuring the cut size. The linkage system is to ensure the consistency of the movements of the double-cutting machine and the middle-cutting machine. Even if the plate moves left or right during production, the linkage system can ensure that the double-cutting machine and the middle-cutting machine move together with the plate, ensuring the consistency of the final cut plate size. This achieves the goal of producing small-sized plates after cutting wide-format plates in the middle.

[0003] While existing technologies can achieve linkage between double-cutting and center-cutting equipment through a linkage system, these systems involve two separate devices, resulting in a large footprint and inconvenient operation. Furthermore, adjustments to the center-cutting and double-cutting equipment are primarily achieved manually through the linkage system, which is complex and difficult to operate. Additionally, when the cutting material shifts during the cutting process, the cutting blade position cannot be adjusted promptly based on the shift, easily leading to cutting deviations and affecting cutting accuracy. In light of the above, this application proposes a double-cutting and center-cutting integrated machine. Utility Model Content

The top right side of the U-shaped moving rod 502 is provided with a first threaded hole that is threaded to the corresponding first screw 501. The threaded connection allows the corresponding U-shaped moving rod 502 to move laterally while the first screw 501 rotates.

The bottom of the U-shaped moving rod 502 is fixedly installed to the top of the corresponding two edge cutters 4 by four T-shaped fixing bolts.

[0036] The support plate 8 is fixedly connected between the inner walls of the two sides of the U-shaped support frame 1. The U-shaped moving rod 502 is sleeved on the support plate 8, and the inner wall of the U-shaped moving rod 502 does not contact the outer side of the support plate 8.

[0037] The second thread drive mechanism 6 consists of two sets, which are installed on the support plate 8 and the U-shaped support frame 1, and are fixedly connected to the top of the corresponding middle cutting blade 3.

[0038] The second threaded drive mechanism 6 includes a second screw 601. Two mounting holes 801 are formed on the top of the support plate 8.

A connecting rod 602 is threaded onto the second screw 601, and a [missing information - likely a typo or typo] is formed on one side of the connecting rod 602. The second threaded hole is threadedly connected to the corresponding second screw 601. The threaded connection allows the corresponding connecting rod 602 to move laterally while the second screw 601 rotates. The bottom end of the connecting rod 602 is fixedly installed to the top of the corresponding middle cutter 3 by four T-shaped fixing bolts. The connecting rod 602 is slidably installed in the corresponding mounting hole 801. A second T-shaped slide rail is fixedly connected between the inner walls of the two sides of the mounting hole 801. A second T-shaped slide groove with openings on both sides is opened on the top of the connecting rod 602. The second T-shaped slide rail is slidably connected to the corresponding second T-shaped slide groove. The second T-shaped slide rail provides a lateral guiding effect for the connecting rod 602.

The output shaft ends of the two second drive motors 603 are fixedly connected to the two ends of the second screw 601 that are far apart from each other.

[0039] The ranging mechanism is installed on the support plate 8, the U-shaped moving rod 502 and the connecting rod 602. The ranging mechanism includes a grating ruler 10 and four photoelectric reading heads 7. The grating ruler 10 is fixedly connected to the front side of the support plate 8. The four photoelectric reading heads 7 are respectively fixedly installed on the front side of the two U-shaped moving rods 502 and the two connecting rods 602. An extension rod is fixedly connected to the front side of the connecting rod 602. The front end of the extension rod is fixedly connected to the corresponding photoelectric reading head 7. The extension rod is used to support the photoelectric reading head 7. All four photoelectric reading heads 7 are located at the lower front side of the grating ruler 10. The photoelectric reading heads 7 read the scale value on the grating ruler 10 to determine the lateral distance of the U-shaped moving rod 502 and the connecting rod 602.

[0040] The PLC controller 9 is fixedly connected to the top left side of the U-shaped support frame 1 and is electrically connected to four photoelectric reading heads 7, two second drive motors 603 and two first drive motors 503.

[0041] In this implementation scheme: The PLC controller 9 pre-sets the on / off scale values ​​of the first drive motor 503 and the second drive motor 603 according to cutting needs. The edge cutter 4 and the center cutter 3 are pre-adjusted to their initial positions. When cutting the moving plate material, the PLC controller 9 controls the first drive motor 503 and the second drive motor 603 to turn on. The first drive motor 503 drives the corresponding first screw 501 to rotate, and the second drive motor 603 drives the corresponding second screw 601 to rotate. Simultaneously, the rotation of the first screw 501 drives the corresponding U-shaped moving rod 502 to move laterally. The U-shaped moving rod 502 drives the corresponding edge cutting blade 4 and photoelectric reading head 7 to move laterally. While the second screw 601 rotates, it drives the corresponding connecting rod 602 to move laterally. The connecting rod 602 drives the corresponding middle cutting blade 3 and photoelectric reading head 7 to move laterally. While the photoelectric reading head 7 moves laterally, it reads the scale line on the grating ruler 10 and transmits its position to the PLC controller 9. When its position reaches the set value, the PLC controller 9 controls the corresponding first drive motor 503 and second drive motor 603 to shut down, so that the edge cutting blade 4 and the middle cutting blade 3 can cut the plate material at the same time.

[0042] It should be noted that the PLC controller 9 is electrically connected to the four photoelectric reading heads 7, the PLC controller 9, the two second drive motors 603, and the two first drive motors 503 via wires. The preferred model of the PLC controller 9 is Siemens SIMATICS 7-1200, the preferred model of the photoelectric reading head 7 is HEIDENHAIN LS 487, and the preferred models of the first drive motors 503 and the second drive motors 603 are Panasonic MINAS. The A6 series operates on the following principle: The cutting position setting is input via the touchscreen of the PLC controller 9. The PLC controller 9 converts the setting into a pulse count and sends pulse signals to the first drive motor 503 and the second drive motor 603. The output shafts of the first drive motor 503 and the second drive motor 603 rotate sequentially, driving the edge cutter 4 and the center cutter 3 to move via their corresponding screws. The photoelectric reading head 7 reads the scale of the grating ruler 8 in real time and feeds back the current position to the PLC controller 9 via the SSI protocol. The PLC controller 9 compares the feedback position with the setting value and dynamically adjusts the speed of the first drive motor 503 and the second drive motor 603 using a PID algorithm. When the position error is ≤ ±0.05mm, the PLC controller 9 cuts off the pulse output, and the first drive motor 503 and the second drive motor 603 brake and stop. Since the PLC controller 9, the four photoelectric reading heads 7, the two second drive motors 603, and the two first drive motors 503 are all existing mature products, their specific principles are existing technology and will not be elaborated further here.

[0043] Furthermore:

[0044] The double-cutting and center-cutting integrated machine also includes two 3D vision cameras 12, which are fixedly connected to the bottom of the inner walls on both sides of the U-shaped support frame 1. The 3D vision cameras 12 are electrically connected to the PLC controller 9.

[0045] In this embodiment, during the cutting process, the 3D vision camera 12 detects the position of the plate material movement in real time. When the plate material movement is detected to be offset, the detected offset direction and offset size are transmitted to the PLC controller 9. The PLC controller 9 controls the corresponding first drive motor 503 or second drive motor 603 to start according to the offset direction and offset size, so as to automatically control the corresponding edge cutting blade 4 or center cutting blade 3 to move laterally for adjustment.

[0046] It should be noted that the 3D vision camera 12 can preferably be a Zivid Two 3D camera. Its specific principle is as follows: the 3D vision camera 12 emits structured light (such as laser grid / infrared speckle) onto the surface of the plate to form a deformed pattern, and receives reflected light to generate a depth map. It converts the depth map into 3D point cloud coordinates through triangulation, and compares the 3D position difference between the current frame and the preset template through the built-in offset detection algorithm, and outputs parameters: horizontal offset ΔX (mm), vertical offset ΔY (mm), and rotation angle θ (°). The parameters are output to the PLC controller 9. The PLC controller 9 executes the action to control the first drive motor 503 or the second drive motor 603 to start according to the decision threshold. Since the 3D vision camera 12 is an existing product, its specific detection principle is existing technology and will not be described in detail here.

[0047] The usage method of this embodiment is as follows: During use, the scale values ​​and offset values ​​for opening and closing the first drive motor 503 and the second drive motor 603 are preset via the PLC controller 9 according to the cutting requirements. The edge cutter 4 and the center cutter 3 are pre-adjusted to their initial positions. After adjustment, when cutting the moving plate, the first drive motor 503 and the second drive motor 603 are turned on via the PLC controller 9. The first drive motor 503 drives the corresponding first screw 501 to rotate, and the second drive motor 603 drives the corresponding second screw 601 to rotate. Simultaneously, the rotation of the first screw 501 drives the corresponding U-shaped moving rod 502 to move laterally. The U-shaped moving rod 502 drives the corresponding edge cutter 4 and photoelectric reading head 7 to move laterally. Simultaneously, the rotation of the second screw 601 drives the corresponding connecting rod 602 to move laterally. The connecting rod 602 drives the corresponding middle cutting blade 3 and photoelectric reading head 7 to move laterally. While the photoelectric reading head 7 moves laterally, it reads the scale lines on the grating ruler 10 and transmits its position to the PLC controller 9. When its position reaches the set value, the PLC controller 9 controls the corresponding first drive motor 503 and second drive motor 603 to shut down. After adjustment, the plate material can be cut simultaneously by the edge cutting blade 4 and the middle cutting blade 3. Compared with the existing technology that uses two devices for cutting, the method of integrating the edge cutting blade 4 and the middle cutting blade 3 into one unit significantly reduces the space occupied. In operation, the PLC controller 9, the grating ruler 10 and the photoelectric reading head 7 work together to automatically control and adjust the position of the edge cutting blade 4 and the middle cutting blade 3, eliminating the need for manual adjustment and reducing the difficulty of operation.

[0048] In addition, during the cutting process, the 3D vision camera 12 detects the position of the plate movement in real time. When the plate movement is detected to be offset, the detected offset direction and offset size are transmitted to the PLC controller 9. The PLC controller 9 controls the corresponding first drive motor 503 or second drive motor 603 to start according to the offset direction and offset size, so as to automatically control the corresponding edge cutter 4 or center cutter 3 to move laterally for adjustment. By adjusting the position of the edge cutter 4 or center cutter 3 when the plate is offset, the cutting size remains unchanged, thereby improving the cutting accuracy.

[0049] Example 2

[0050] Reference Figure 3This embodiment differs from Embodiment 1 in that: the tops of the four edge cutting blades 4 and the tops of the two middle cutting blades 3 are all fixedly connected to external threaded blocks 11. The U-shaped moving rod 502 and the connecting rod 602 are respectively threaded onto the corresponding external threaded blocks 11. The bottoms of the U-shaped moving rod 502 and the connecting rod 602 are provided with threaded grooves, which are threadedly connected to the corresponding external threaded blocks 11. The tops of the four edge cutting blades 4 and the two middle cutting blades 3 are fixedly connected to the U-shaped moving rod 502 and the connecting rod 602 through the corresponding external threaded blocks 11. The threaded connection of the external threaded blocks 11 facilitates the subsequent removal of the edge cutting blades 4 and the middle cutting blades 3.

[0051] The method of use in this embodiment is as follows: The difference from the first embodiment is that it also has the following functions: the edge cutting blade 4 and the middle cutting blade 3 are respectively threadedly connected to the U-shaped moving rod 502 and the connecting rod 602 through the corresponding external threaded block 11. When the edge cutting blade 4 and the middle cutting blade 3 are replaced or repaired in the future, the edge cutting blade 4 and the middle cutting blade 3 can be directly removed by simply rotating them, which provides convenience for subsequent replacement or repair work.
