Description

Technical Field

[0001] This invention relates to the field of laser plate-making equipment technology, and in particular to a large-size laser plate-making device and method thereof. Background Technology

[0002] Laser plate making uses a laser beam to melt a designated area of ​​the printing plate and remove unwanted parts. The printing plate made by laser plate making is an indispensable part of the printing process, serving as the medium for transferring ink onto the substrate. Currently, most laser plate making equipment on the market has significant limitations on the size of the plate. This makes it difficult to complete the printing of large printed materials with a single plate, while the quality of printed materials printed by splicing multiple small plates is difficult to control, often resulting in gaps at the seams that affect the appearance of the product.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN113878978A, patent name: a screen printing plate laser plate making machine) is as follows: the screen printing plate carrying mechanism includes a Y-axis drive mechanism disposed on both sides of the worktable and a base plate disposed on the Y-axis drive mechanism. The base plate is provided with pads for placing the screen printing plate and pneumatic clamping devices for fixing the screen printing plate. The pneumatic clamping devices are disposed on the four sides of the base plate.

[0004] As can be seen from the above implementation plan, when the screen printing laser plate making machine is making screen printing plates, the screen frame of the screen printing plate can only be placed on the screen printing plate carrying mechanism, and the size of the screen printing plate carrying mechanism determines the size of the screen frame. Therefore, the size of the screen printing plates that the screen printing laser plate making machine can make is greatly limited, and the range of adaptability is small. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art by providing plate moving components on both sides of the assembly frame. The plate moving components can move the plate making body into the assembly frame, and the laser component can perform segmented laser plate making on large plate making bodies. Therefore, it solves the problem that the size of the plate making body is limited by the size of the plate moving components of the equipment. Compared with traditional laser plate making equipment, it has a wider range of adaptability and can produce larger plate sizes.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] A large-size laser plate-making device includes a laser assembly, which includes a laser head. An assembly frame is provided on one side of the laser assembly, and at least one set of plate-making moving components are provided on both sides of the assembly frame. Each plate-making moving component includes two powered clamping rollers with an adjustable distance between them. The two powered clamping rollers can rotate to drive the plate-making body to move. An upper clamping component is provided at the upper end of the plate-making moving component, and a lower support component is provided at the lower end. The powered clamping rollers clamp the plate-making body from the front and rear sides, while the lower support component and the upper clamping component clamp the plate-making body from the upper and lower ends. The plate-making body is input from one end of the assembly frame and output from the other end of the assembly frame.

[0008] Furthermore, the plate-making moving assembly includes an upper mounting component, which is connected to an upper power mechanism. The upper end of the power clamping roller is connected to the upper power mechanism, and the lower end of the power clamping roller is connected to a lower power mechanism. The lower power mechanism is connected to the lower mounting component.

[0009] Furthermore, the upper mounting component includes a first motor mounting base, a movable slide is provided on the side of the first motor mounting base, a first sliding block and a second sliding block are slidably connected to the movable slide, and a first slide rail base is provided below the movable slide;

[0010] The upper power mechanism includes a first motor, the first motor is connected to a first drive gear, the first motor is connected to a first motor mounting base, the first drive gear is meshed with a first transmission gear, the first transmission gear is coaxially connected with a second transmission gear, and both sides of the second transmission gear are meshed with a first rack.

[0011] The first rack is slidably connected to the first slide rail seat. One end of the first rack is connected to a first seated bearing. The power clamping roller is connected to the first seated bearing. The upper end of the power clamping roller is connected to a first rotating gear. The first rotating gear is meshed with a second driving gear. The second driving gear is connected to a second motor.

[0012] The second motor is connected to the first sliding block, and the second drive gear is connected to the second sliding block.

[0013] Furthermore, the lower mounting component includes a second motor mounting base and a second slide rail base, and the lower power mechanism includes a third motor connected to the second motor mounting base. The third motor is connected to a third drive gear, which meshes with a third transmission gear. The third transmission gear is coaxially connected with a fourth transmission gear. The fourth transmission gear has second racks meshing with both sides, and the second racks are slidably connected to the second slide rail base. One end of the second rack is connected to a second bearing seat, and the end of the power clamping roller away from the first bearing seat is connected to the second bearing seat.

[0014] Furthermore, the upper clamping assembly includes a lifting power component and a linear bearing. The output end of the lifting power component is connected to the lifting base, and a linear rod is slidably inserted into the linear bearing. One end of the linear rod is connected to the lifting base.

[0015] The lifting base is equipped with an upper clamping motor, which is connected to an upper clamping gear. Upper clamping racks are meshed on both sides of the upper clamping gear, and the upper clamping racks are slidably connected in the upper rack slide.

[0016] Furthermore, an upper clamping adjustment slide rail is provided on the side of the lifting base away from the lifting power component. The upper clamping adjustment slide rail is connected to two opposing upper clamping seats, and the upper clamping seats are rotatably connected to upper clamping rollers.

[0017] One end of the upper clamping rack is connected to the upper clamping seat.

[0018] Furthermore, the assembly frame, laser component, and plate-making moving component are all mounted on the base assembly, which includes a base body with auxiliary rollers on both sides.

[0019] Furthermore, the lower support assembly is located at the upper middle part of the base body. The lower support assembly includes a dovetail slide rail, on which a first dovetail slide seat and a second dovetail slide seat are slidably connected. The base body is rotatably connected to an adjusting bolt, which is threadedly connected to the first dovetail slide seat. The adjusting bolt is threadedly connected to an adjusting nut, which is located on the outside of the base body. The base body is threadedly connected to a top-load bolt, one end of which abuts against the first dovetail slide seat. The top-load bolt is threadedly connected to an adjusting nut.

[0020] The side of the seat away from the top force bolt is connected to a clamping power component, and the output end of the clamping power component is connected to a second dovetail slide.

[0021] Furthermore, the first dovetail slide is provided with a load-bearing wheel, which includes a first cylinder and a second cylinder arranged coaxially. The second cylinder is located on the side of the first cylinder away from the top force bolt, and the diameter of the second cylinder is smaller than the diameter of the first cylinder.

[0022] The second dovetail slide is provided with a clamping seat, and the clamping seat is rotatably connected to a clamping roller. The cylindrical cross-section of the clamping roller is perpendicular to the cylindrical cross-section of the second cylinder, and the lower cylindrical end face of the clamping roller is higher than the upper end face of the cylindrical cross-section of the second cylinder.

[0023] The method for laser plate making using large-size laser plate making equipment includes the following steps:

[0024] A. Adjust the plate-making moving component of the assembly frame so that the distance between the two opposing power clamping rollers of the plate-making moving component is greater than the thickness of the plate body to be clamped. Adjust the upper clamping component so that the distance between the bottom of the upper clamping component and the lower support component is higher than the height of the plate body to be clamped.

[0025] B. Place the lower side of the printing plate against the auxiliary roller, and use the support of the auxiliary roller to push the printing plate between the two power clamping rollers.

[0026] C. Adjust the position of the load-bearing roller by adjusting the bolts so that when the printing body is pushed between the two power clamping rollers, one side of the printing body is just tangent to the surface where the first cylinder and the second cylinder are connected.

[0027] D. Since the upper end of the auxiliary roller and the upper end of the second cylinder of the load-bearing roller are on the same horizontal plane, when the printing body is pushed between the two power clamping rollers, the lower end of the printing body abuts against the upper end surface of the second cylinder.

[0028] E. The clamping power unit pushes the second dovetail slide towards the first dovetail slide, so that the clamping roller abuts against the side of the molded body away from the first cylinder. At this point, the first cylinder and the clamping roller clamp the lower end of the molded body, and the second cylinder supports the downward gravity of the molded body.

[0029] F. The lifting power unit pushes the lifting base downward, so that the upper clamping rollers are on both sides of the upper end of the template body. The upper clamping motor drives the upper clamping rack, so that the upper clamping rollers on both sides of the upper end of the template body move towards the middle, so that the upper clamping rollers clamp the upper end of the template body. At this point, the template body is clamped in the assembly frame.

[0030] G. Driven by the moving mechanism of the laser assembly, the laser head performs laser plate making on the plate making body between the plate making moving components on both sides of the assembly frame. After one end of the plate making body is completed, the power clamping roller rolls and pushes the plate making body towards the exit of the assembly frame. The other part of the plate making body that has not undergone laser plate making falls between the plate making moving components on both sides of the assembly frame. The laser head continues to perform plate making on the part of the plate making body that has just fallen between the plate making moving components on both sides of the assembly frame. As the laser head performs laser plate making on the plate making body, the part of the plate making body that has completed laser plate making is gradually pushed out of the assembly frame, while the part that has not undergone laser plate making is gradually fed into the assembly frame until the entire plate making body is laser plate made.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] The assembly frame is equipped with plate moving components on both sides, which can move the plate making body into the assembly frame. The lower support component can provide gravity support and transmission for the plate making body, and the upper clamping component can limit and clamp the upper part of the plate making body. The laser component can perform segmented laser plate making on large plate making bodies. Therefore, it solves the problem that the size of the plate making body is limited by the size of the plate moving component of the equipment. Compared with traditional laser plate making equipment, it has a wider range of adaptability and can produce larger plate sizes. Attached Figure Description

[0044] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0045] like Figures 1 to 9As shown, a large-size laser plate-making device includes a laser assembly 3, which includes a laser head 301. An assembly frame 2 is provided on one side of the laser assembly 3. At least one set of plate-making moving components 4 are provided on both sides of the assembly frame 2. The assembly frame 2, laser assembly 3, and plate-making moving components 4 are all mounted on a base assembly 1, which includes a base body 101. Auxiliary rollers 102 are provided on both sides of the base body 101. In this embodiment, two sets of plate-making moving components 4 are provided on both sides of the assembly frame 2. When the two sets of plate-making moving components 4 clamp the plate-making body 7, two lines on the plate-making body 7 are clamped, further ensuring the straightness of the plate-making body 7 during movement. When only one end of the plate-making body 7 is input into the assembly frame 2, or when most of the front end of the plate-making body 7 has moved out of the assembly frame 2, leaving only the rear end of the plate-making body 7 remaining in the assembly frame 2 for laser plate-making, the plate-making body 7 can still be perpendicular to the laser point of the laser head 301, ensuring the accuracy of laser plate-making.

[0046] Traditional laser plate-making equipment can only clamp the plate onto the plate-making support component, and then the laser head 301 moves to perform laser plate-making. Therefore, the size of the plate is greatly limited by the plate-making support component. A plate-making support component of a certain size can only be used to make a smaller plate body 7. However, in the plate-making equipment of the present invention, since the plate-making moving component 4 can move the plate body 7, the laser component 3 can perform laser plate-making on the same plate body 7 in batches. Therefore, as long as the height of the plate body 7 does not exceed the maximum clamping distance between the lower support component 5 and the upper clamping component 6, the length of the plate body 7 is not limited. Therefore, the plate-making equipment of the present invention has a wider range of applications. Compared with traditional laser plate-making equipment, it can produce larger plate bodies 7. Furthermore, since the plate body 7 is vertically held during laser plate-making, the entire machine makes better use of vertical space, resulting in a smaller footprint and allowing for greater utilization of the production workshop area.

[0047] The plate-making moving assembly 4 includes two powered clamping rollers 403. The distance between the two powered clamping rollers 403 is adjustable, so the two powered clamping rollers 403 can clamp plate bodies 7 of different thicknesses, making it highly adaptable. The two powered clamping rollers 403 can rotate to drive the plate body 7 to move. Therefore, whether the plate body 7 has just been entered into the assembly frame 2 or the tail end of the plate body 7 is about to leave the assembly frame 2, the plate body 7 can receive power transmission from the powered clamping rollers 403, and no manual pulling is required.

[0048] The upper end of the plate-making moving component 4 is provided with an upper clamping component 6, and the lower end of the plate-making moving component 4 is provided with a lower support component 5. The power clamping roller 403 clamps the plate-making body 7 from the front and rear sides, and the lower support component 5 and the upper clamping component 6 clamp the plate-making body 7 from the upper and lower ends. The plate-making body 7 is input from one end of the assembly frame 2 and finally output from the other end of the assembly frame 2. When the plate-making body 7 enters the assembly frame 2, its upper, lower, front and back are restricted, thus ensuring that it can be in a stable state during the laser plate-making process and ensuring the accuracy of laser plate-making.

[0049] The plate-making moving assembly 4 includes an upper mounting component 401, which is connected to an upper power mechanism 402. The upper end of the power clamping roller 403 is connected to the upper power mechanism 402, and the lower end of the power clamping roller 403 is connected to a lower power mechanism 404. The lower power mechanism 404 is connected to the lower mounting component 405. Since the power clamping roller 403 is relatively long, power mechanisms are provided at both the upper and lower ends of the power clamping roller 403. The upper power mechanism 402 and the lower power mechanism 404 simultaneously adjust the two power clamping rollers 403 to move closer or further apart, so that when the two power clamping rollers 403 clamp the plate-making body 7, the force at the upper and lower ends is uniform, and there is no problem of one end having a larger clamping force and the other end having a smaller clamping force. This ensures the stability of the plate-making body 7 during operation and also ensures the accuracy of the movement of the plate-making body 7.

[0050] The upper mounting component 401 includes a first motor mounting base 4011, a movable slide block 4012 is provided on the side of the first motor mounting base 4011, a first sliding block 4013 and a second sliding block 4014 are slidably connected to the movable slide block 4012, and a first slide rail seat 4015 is provided below the movable slide block 4012; the upper power mechanism 402 includes a first motor 4021, the first motor 4021 is connected to a first drive gear 4022, the first motor 4021 is connected to the first motor mounting base 4011, the first drive gear 4022 is meshed with a first transmission gear 4023, the first transmission gear 4023 is coaxially connected with a second transmission gear 4024, and the second transmission gear 4024 has two... Both sides are meshed with the first rack 4025; the first rack 4025 is slidably connected to the first slide rail seat 4015, and one end of the first rack 4025 is connected to the first bearing 40251. The power clamping roller 403 is connected to the first bearing 40251. Therefore, the first motor 4021 drives the first drive gear 4022 to rotate. The first drive gear 4022 drives the first transmission gear 4023 and the second transmission gear 4024 to rotate, thereby realizing that the first racks 4025 on both sides of the second transmission gear 4024 move towards the middle at the same time or move towards both sides at the same time. Thus, the two power clamping rollers 403 are driven to clamp the printing body 7 towards the middle or move away from both sides to release the printing body 7.

[0051] The upper end of the power clamping roller 403 is connected to a first rotating gear 4028, which meshes with a second driving gear 4027. The second driving gear 4027 is connected to a second motor 4026. Therefore, both power clamping rollers 403 have the power to rotate. When the two power clamping rollers 403 rotate in opposite directions, they can push the printing body 7 to move.

[0052] The second motor 4026 is connected to the first sliding block 4013, and the second drive gear 4027 is connected to the second sliding block 4014. Therefore, the second motor 4026 moves left and right with the power clamping roller 403, making the rotational power transmitted by the second motor 4026 to the power clamping roller 403 more precise, and making the pushing distance of the power clamping roller 403 when moving the printing body 7 more precise.

[0053] The lower mounting component 405 includes a second motor mounting base 4051 and a second slide rail base 4052. The lower power mechanism 404 includes a third motor 4041, which is connected to the second motor mounting base 4051. The third motor 4041 is connected to a third drive gear 4042, which meshes with a third transmission gear 4043. The third transmission gear 4043 is coaxially connected with a fourth transmission gear 4044. Second racks 4045 are meshed on both sides of the fourth transmission gear 4044. The second racks 4045 are slidably connected to the second slide rail base 4052. One end of 5 is connected to the second bearing 40451. The end of the power clamping roller 403 away from the first bearing 40251 is connected to the second bearing 40451. Therefore, when the upper and lower ends of the power clamping roller 403 move, they are controlled by separate power. Because the power clamping roller 403 is relatively long, the power at both ends is separated to control its movement, so that the force of the power clamping roller 403 when clamping the printing body 7 is more uniform. There will be no situation where the clamping force at one end is large and the clamping force at the other end is small. Therefore, the process of the power clamping roller 403 pushing the printing body 7 to move is more precise.

[0054] The upper clamping assembly 6 includes a lifting power component 601 and a linear bearing 603. In this embodiment, the lifting power component 601 can be a cylinder, an electric cylinder, or a combination of a motor and a module. The output end of the lifting power component 601 is connected to the lifting base 602. The linear bearing 603 is slidably inserted with a linear rod 604. One end of the linear rod 604 is connected to the lifting base 602. Both the lifting power component 601 and the linear bearing 603 are connected to the upper end of the assembly frame 2.

[0055] An upper clamping motor 606 is mounted on the lifting base 602. The upper clamping motor 606 is connected to an upper clamping gear 607. Upper clamping racks 608 are meshed on both sides of the upper clamping gear 607. The upper clamping racks 608 are slidably connected in an upper rack slide block 6081. An upper clamping adjusting slide rail 605 is mounted on the side of the lifting base 602 away from the lifting power component 601. The upper clamping adjusting slide rail 605 is connected to two opposing upper clamping seats 609. Upper clamping seats 609 are rotatably connected to upper clamping rollers 60. 91. One end of the upper clamping rack 608 is connected to the upper clamping seat 609. Therefore, the upper clamping motor 606 drives the upper clamping gear 607 to rotate, thereby causing the upper clamping rack 608 to move towards the middle or to both sides at the same time. It also drives the two opposite upper clamping seats 609 to move towards the middle, so that the upper clamping roller 6091 clamps the upper end of the printing body 7, or simultaneously drives the two opposite upper clamping seats 609 to move to both sides, so that the upper clamping roller 6091 releases the upper end of the printing body 7.

[0056] The lower support assembly 5 is located at the upper middle part of the base 101. The lower support assembly 5 includes a dovetail slide rail 501, on which a first dovetail slide seat 502 and a second dovetail slide seat 508 are slidably connected. The base 101 is rotatably connected to an adjusting bolt 505, which is threadedly connected to the first dovetail slide seat 502. An adjusting nut 506 is threadedly connected to the adjusting bolt 505, located on the outside of the base 101. A top-load bolt 504 is threadedly connected to the base 101, with one end of the top-load bolt 504 abutting against the first dovetail slide seat 502. The top-load bolt 504 is also threadedly connected to the adjusting nut 506, allowing for adjustments based on actual needs. The position of the first dovetail slide 502 is adjusted by manually rotating the adjusting bolt 505. After the position of the first dovetail slide 502 is determined, the adjusting nut 506 is tightened so that the adjusting nut 506 is pressed against the outside of the seat body 101, so that the adjusting bolt 505 will not rotate during the entire operation and will not affect the position of the first dovetail slide 502. In order to enable the first dovetail slide 502 to withstand greater force when the load-bearing roller 503 and the clamping roller 5091 clamp the bottom of the manufacturing body 7, a top force bolt 504 is set to abut against the first dovetail slide 502, so that the force on one side of the first dovetail slide 502 is more even.

[0057] A clamping power component 507 is connected to the side of the seat 101 away from the top force bolt 504. The output end of the clamping power component 507 is connected to the second dovetail slide 508. A load-bearing wheel 503 is provided on the first dovetail slide 502. The load-bearing wheel 503 includes a first cylinder 5031 and a second cylinder 5032 arranged coaxially. The second cylinder 5032 is located on the side of the first cylinder 5031 away from the top force bolt 504. The diameter of the second cylinder 5032 is smaller than the diameter of the first cylinder 5031. The upper end of the auxiliary roller 102 is on the same horizontal plane as the upper end of the second cylinder 5032 of the load-bearing wheel 503. Therefore, when the printing body 7 is pushed between the two power clamping rollers 403, the lower end of the printing body 7 abuts against the upper end face of the second cylinder 5032.

[0058] The second dovetail slide 508 is provided with a clamping seat 509, and the clamping seat 509 is rotatably connected to a clamping roller 5091. The cylindrical cross-section of the clamping roller 5091 is perpendicular to the cylindrical cross-section of the second cylinder 5032, and the lower cylindrical end face of the clamping roller 5091 is higher than the upper end face of the cylindrical cross-section of the second cylinder 5032. The clamping power component 507 pushes the second dovetail slide 508 toward the first dovetail slide 502, so that the clamping roller 5091 abuts against the side of the printing body 7 away from the first cylinder 5031. The first cylinder 5031 and the clamping roller 5091 clamp the lower end of the printing body 7. Since the load-bearing wheel 503 and the clamping roller 5091 can rotate, it is beneficial for the printing body 7 to move above them.

[0059] The method for laser plate making using large-size laser plate making equipment includes the following steps:

[0060] A. Adjust the plate-making moving component 4 of the assembly frame 2 so that the distance between the two opposing power clamping rollers 403 of the plate-making moving component 4 is greater than the thickness of the plate-making body 7 to be clamped. Adjust the upper clamping component 6 so that the distance between the lowest end of the upper clamping component 6 and the lower support component 5 is higher than the height of the plate-making body 7 to be clamped.

[0061] B. Place the lower side of the printing plate 7 against the auxiliary roller 102, and use the support of the auxiliary roller 102 to push the printing plate 7 between the two power clamping rollers 403.

[0062] C. Adjust the position of the load-bearing roller 503 by adjusting the bolt 505 so that when the printing body 7 is pushed between the two power clamping rollers 403, one side of the printing body 7 is just tangent to the surface where the first cylinder 5031 and the second cylinder 5032 are connected.

[0063] D. Since the upper end of the auxiliary roller 102 and the upper end of the second cylinder 5032 of the load-bearing roller 503 are on the same horizontal plane, when the manufacturing body 7 is pushed between the two power clamping rollers 403, the lower end of the manufacturing body 7 abuts against the upper end surface of the second cylinder 5032.

[0064] E. The clamping power unit 507 pushes the second dovetail slide 508 toward the first dovetail slide 502, so that the clamping roller 5091 abuts against the side of the molded body 7 away from the first cylinder 5031. At this point, the first cylinder 5031 and the clamping roller 5091 clamp the lower end of the molded body 7, and the second cylinder 5032 supports the downward gravity of the molded body 7.

[0065] F. The lifting power unit 601 pushes the lifting base 602 downward, so that the upper clamping rollers 6091 are on both sides of the upper end of the manufacturing body 7. The upper clamping motor 606 drives the upper clamping rack 608, so that the upper clamping rollers 6091 on both sides of the upper end of the manufacturing body 7 move towards the middle, so that the upper clamping rollers 6091 clamp the upper end of the manufacturing body 7. At this point, the manufacturing body 7 is clamped in the assembly frame 2.

[0066] G. Driven by the moving mechanism of the laser component 3, the laser head 301 performs laser plate making on the plate making body 7 between the plate making moving components 4 on both sides of the assembly frame 2. After one end of the plate making body 7 is completed, the power clamping roller 403 rolls and pushes the plate making body 7 towards the exit of the assembly frame 2. Then, the other part of the plate making body 7 that has not undergone laser plate making falls into the plate making moving components 4 on both sides of the assembly frame 2. The laser head 301 continues to perform plate making on the part of the plate making body 7 that has just fallen into the plate making moving components 4 on both sides of the assembly frame 2. As the laser head 301 performs laser plate making on the plate making body 7, the part of the plate making body 7 that has completed laser plate making is gradually pushed out of the assembly frame 2, while the part that has not undergone laser plate making is gradually fed into the assembly frame 2, until the entire plate making body 7 is completed.
