Description

Technical Field

[0001] This utility model relates to the field of offset printing and coding technology, and in particular to a roller clamping device for adding coding to an offset printing machine. Background Technology

[0002] Offset printing machines are printing devices that use the principle of oil and water repulsion to transfer images and text onto the substrate through a rubber blanket roller. The offset printing machine equipped with a coding roller clamping device is an auxiliary device designed for the need to print variable information during the offset printing process. Its main function is to ensure that the coding head and the substrate maintain a stable and appropriate contact pressure during the coding process, thereby ensuring the coding quality.

[0003] A search revealed Chinese Patent Publication No. CN219214397U, which discloses a roller clamping device for adding inkjet printing to an offset printing machine. The device is positioned above the substrate conveying roller of the offset printing machine, and a detachable mounting and fixing part is installed on the machine. Multiple clamping components are arranged axially on the fixing part. The printhead of the inkjet printing device is located between any two clamping components. When the substrate to be printed is below the printhead, each clamping component includes a fixing block and a roller on one side. The fixing block is installed on the fixing part, and the roller is circumferentially connected to the substrate. This utility model describes a roller clamping device for adding inkjet printing to an offset printing machine, applicable to various industries. The moving rollers flatten the substrate, preventing the substrate from being squeezed due to asynchronous movement of the rollers and the cylinders, without adding extra power. At the same time, this structure can be installed on existing finished equipment without disassembling the equipment, which can be completed without disassembly. The assembly cost is low and the reliability is high. However, in the existing offset printing machines with roller clamping devices for inkjet printing, the roller clamping device can adapt to a certain range of material thickness and texture changes. It cannot adapt well to smooth, rough, or unevenly thick materials. The rollers are prone to slippage and cannot provide stable clamping force. For materials with uneven thickness, it is difficult to ensure that the entire material surface can be uniformly controlled for transmission and clamping. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a roller pressing device for adding inkjet printing to an offset printing machine. It aims to improve the problems in the prior art where the roller pressing device cannot adapt well, the roller is prone to slippage, it cannot provide stable pressing force, and it is difficult to ensure that the entire material surface can be uniformly controlled for transmission and pressing for materials with uneven thickness.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a roller clamping device for adding inkjet printing to an offset printing machine, comprising a fixed frame and a belt. A support frame is fixedly connected to the top of the outer wall of the fixed frame. A motor is fixedly connected to the front side of the inner wall of the fixed frame. A first rotating wheel is fixedly connected to the output end of the motor. Fixed plates are fixedly connected to the front and rear sides of the inner wall of the fixed frame. A second rotating wheel is rotatably connected to the front side of the outer wall of the front fixed plate. The second rotating wheel is driven by the first rotating wheel through the belt. The rear side of the outer wall of the second rotating wheel is fixedly connected to the first rotating wheel. A gear is fixedly connected to the first gear. Gears 2 are rotatably connected to the left and right sides of the outer wall of the front fixed plate. The gears 2 mesh with the first gear. Rollers are rotatably connected to the rear sides of the outer walls of the two gears 2. Threaded rods are threadedly connected to the top of the inner walls of the multiple fixed plates. Lifting plates are rotatably connected to the outer walls of the threaded rods. Rolling shafts are rotatably connected to adjacent sides of the inner walls of the lifting plates. A sprayer is installed on the left side of the outer wall of the rolling shaft. A correction mechanism is fixedly connected to the right side of the inner wall of the fixed frame. The correction mechanism is used to correct the deviation of the transported items.

[0006] The above technical solution involves a motor serving as the power source, installed on the front side of the inner wall of the fixed frame. After the motor is started, rollers one and two transmit power via belt drive. Roller two drives gears one and two to rotate synchronously in opposite directions. The roller, driven by gear two, propels the offset printing material forward, ensuring stable material transmission. The fixed plate is connected to the lifting plate via a threaded rod, enabling the rolling shaft to move up and down and adjust its distance from the roller. As the rolling shaft rotates, the spraying machine rotates synchronously, performing inkjet printing on the offset printing material, thus achieving the inkjet printing function on the offset printing machine. A correction mechanism on the right side of the inner wall of the fixed frame monitors and corrects item deviation in real time, ensuring that the item is transmitted along the predetermined path.

[0007] As a further description of the above technical solution:

[0008] The correction mechanism includes an electric push rod, which is fixedly connected to the right side of the inner wall of the fixed frame. The output end of the electric push rod is fixedly connected to a ratchet groove. A turntable is rotatably connected to the middle of the inner wall of the ratchet groove. A pawl is rotatably connected to one side of the inner wall of the turntable. A spring plate is provided at the bottom of the outer wall of the pawl. A lever is fixedly connected to one side of the outer wall of the turntable. An adjusting rod is rotatably connected to the adjacent side of the inner wall of the ratchet groove.

[0009] The above technical solution involves an electric push rod installed on the right side of the inner wall of the fixed frame, responsible for outputting linear thrust for correction. The thrust is transmitted through the ratchet groove, causing the turntable to rotate in one direction. The lever swings accordingly, pushing the component to change direction. The adjusting rod adjusts the position and angle of the ratchet groove to adapt to different needs. After correction is complete, the electric push rod stops, and the spring plate ensures that the pawl remains engaged with the ratchet groove, preventing reverse deviation.

[0010] As a further description of the above technical solution:

[0011] An adjusting frame is slidably connected to the rear side of the outer wall of the spraying machine, and a bolt is threadedly connected to both the front and rear sides of the inner wall of the adjusting frame.

[0012] The above technical solution involves adjusting and fixing the rear adjustment bracket on the outer wall of the spraying machine using an inner wall bolt. Loosen bolt one to accommodate the coding requirements of different items, then tighten bolt one after adjustment to ensure the adjustment bracket is fixed in position to the spraying machine.

[0013] As a further description of the above technical solution:

[0014] The top of the outer walls of the two fixing plates are fixedly connected to fixing rods, and the left and right ends of the outer walls of the fixing rods are threaded with two bolts.

[0015] The above technical solution involves connecting and reinforcing the fixing plate with a fixing rod, and adjusting the tightness of the bolts by rotating them to ensure structural stability.

[0016] As a further description of the above technical solution:

[0017] The support frame is fixedly connected to the front and rear sides of the top, and the top left and right sides of the gasket are threaded with three bolts.

[0018] Through the above technical solution: the gasket is located at the top of the support frame for cushioning and protection, preventing damage to the support frame surface when the bolts are tightened. Tightening the bolts ensures stable installation of the components and allows for adjustment of position and tightness, ensuring tight and reasonable connection of all parts of the device and guaranteeing the normal operation of the offset printing machine's inkjet roller clamping device.

[0019] As a further description of the above technical solution:

[0020] A wear-resistant block is fixedly connected to the bottom of the outer wall of the motor, and a buffer pad is fixedly connected to the bottom of the outer wall of the wear-resistant block.

[0021] The above technical solution involves wear-resistant blocks and buffer pads at the bottom of the motor. The wear-resistant blocks reduce frictional loss, and the buffer pads dampen vibrations, thereby reducing the impact of motor operation vibrations and ensuring equipment stability.

[0022] As a further description of the above technical solution:

[0023] The top of the outer wall of the spraying machine is equipped with an insertion hole, and the top of the outer wall of the spraying machine is provided with an exhaust hole.

[0024] The above technical solution allows for easy connection of external power and data via the socket on the top of the spraying machine, and the exhaust port removes excess gas, ensuring smooth coding operation.

[0025] As a further description of the above technical solution:

[0026] A throttle handle is fixedly connected to the top of the outer wall of the two threaded rods, and foot supports are fixedly connected to the left and right sides of the bottom of the fixing frame.

[0027] The above technical solution involves fixing the throttle to the top of the threaded rod, and rotating the throttle to adjust the threaded rod to adjust the height of the lifting plate and the rolling shaft to adapt to different pressing requirements; the foot support is located at the bottom of the fixed frame to ensure the stability of the device during operation.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the roller pressing device uses a motor as a power source, which drives the first rotating wheel, which in turn drives the second rotating wheel via belt transmission. The first gear on the second rotating wheel drives the second gear, which in turn drives the roller to transport the offset printing material. By rotating the threaded rod, the height of the lifting plate can be adjusted, and the distance between the pressing shaft and the roller can be changed to achieve pressing. At the same time, the spraying machine on the pressing shaft completes the inkjet printing during material transportation, which reduces assembly costs and improves reliability.

[0030] 2. In this utility model, the electric push rod is fixed to the right side of the fixed frame. After starting, it pushes the ratchet groove. The pawl engages with the ratchet groove under the action of the spring plate, driving the turntable to rotate in one direction. The lever on the turntable swings to achieve correction. The adjusting rod can adjust the mechanism parameters to adapt to different needs. After correction is completed, it remains in a locked state. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a roller clamping device for adding inkjet printing to an offset printing machine, comprising a fixed frame 1 and a belt 6. A support frame 3 is fixedly connected to the top of the outer wall of the fixed frame 1. A motor 4 is fixedly connected to the front side of the inner wall of the fixed frame 1. A first roller 5 is fixedly connected to the output end of the motor 4. Fixed plates 7 are fixedly connected to the front and rear sides of the inner wall of the fixed frame 1. A second roller 8 is rotatably connected to the front side of the outer wall of the front fixed plate 7. The second roller 8 is connected to the first roller 5 via the belt 6. A first gear 9 is fixedly connected to the rear side of the outer wall of the second roller 8. A second gear 10 is rotatably connected to both the left and right sides of the outer wall of the front fixed plate 7. Gear 2 10 meshes with gear 1 9. Rollers 11 are rotatably connected to the rear outer walls of the two gears 2 10. Threaded rods 12 are threadedly connected to the top inner walls of multiple fixed plates 7. Lifting plates 13 are rotatably connected to the outer walls of threaded rods 12. Rolling shafts 14 are rotatably connected to the adjacent inner walls of lifting plates 13. A sprayer 15 is installed on the left side of the outer wall of the rolling shaft 14. A correction mechanism 2 is fixedly connected to the right side of the inner wall of the fixed frame 1. The correction mechanism 2 is used to correct the conveying of items. An adjusting frame 16 is slidably connected to the rear outer wall of the sprayer 15. Bolts 17 are threadedly connected to the front and rear inner walls of the adjusting frame 16.

[0040] Specifically, motor 4, as the power source, is fixed to the front side of the inner wall of the fixed frame 1. After starting, motor 4 drives the first rotating wheel 5 to rotate, which is connected to the second rotating wheel 8 via belt 6 to transmit power. The second rotating wheel 8 drives the first gear 9 to rotate, and the first gear 9 meshes with the second gear 10, causing the two gears 10 to rotate synchronously in opposite directions. The roller 11 rotates under the drive of the second gear 10, which is used to push the offset printing material forward to ensure continuous and stable material transmission. The top of the fixed plate 7 is threadedly connected to the threaded rod 12. The lifting plate 13 moves up and down by rotating the threaded rod 12. The rolling shaft 14 is connected to the lifting plate 13 and can adjust the distance between it and the roller 11. When the rolling shaft 14 rotates, the ink is sprayed... The coating machine 15 rotates synchronously to perform inkjet printing on the offset printing material, realizing the addition of inkjet printing function to the offset printing machine. The correction mechanism 2 on the right side of the inner wall of the fixed frame 1 monitors and corrects the deviation of the transported items in real time to ensure that the items are transported along the predetermined path. The adjustment frame 16 on the rear side of the outer wall of the coating machine 15 is adjusted and fixed by bolts 17 on the front and rear sides of the inner wall. When the bolts 17 are loosened, the adjustment frame 16 can slide relative to the coating machine 15 to adjust the position and angle of the coating machine 15 to adapt to the inkjet printing requirements of different transported items. After adjustment, the bolts 17 are tightened to fix the relative position of the adjustment frame 16 and the coating machine 15, ensuring that the inkjet printing work is accurate and stable.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The correction mechanism 2 includes an electric push rod 201, which is fixedly connected to the right side of the inner wall of the fixed frame 1. The output end of the electric push rod 201 is fixedly connected to a ratchet groove 202. A turntable 203 is rotatably connected to the middle of the inner wall of the ratchet groove 202. A pawl 205 is rotatably connected to one side of the inner wall of the turntable 203. A spring plate 204 is provided at the bottom of the outer wall of the pawl 205. A lever 206 is fixedly connected to one side of the outer wall of the turntable 203. An adjusting rod 207 is rotatably connected to the adjacent side of the inner wall of the ratchet groove 202. A fixing rod 18 is fixedly connected to the top of the outer wall of the two fixing plates 7. Bolts 19 are threadedly connected to the left and right ends of the outer wall of the fixing rod 18. Shims 20 are fixedly connected to the front and rear sides of the top of the support frame 3. Bolts 21 are threadedly connected to the left and right sides of the top of the shims 20.

[0042] Specifically, the electric push rod 201 is installed on the right side of the inner wall of the fixed frame 1, and is used to output linear thrust for correction. The thrust is transmitted through the ratchet groove 202, causing it to move in a set direction and providing initial power for correction. The turntable 203 is connected to the ratchet groove 202, and the pawl 205 is held in engagement with the ratchet groove 202 by the spring plate 204. When the ratchet groove 202 moves, the pawl 205 interacts with it, causing the turntable 203 to rotate unidirectionally. The lever 206 on the turntable 203 swings, pushing the component that needs correction to change direction. The adjusting rod 207 is used to adjust the position and angle of the ratchet groove 202 to adapt to different correction requirements. After correction is completed, the electric push rod 201... 1. Stop. Spring plate 204 ensures that pawl 205 and ratchet groove 202 remain engaged to prevent reverse displacement. The two fixing plates 7 are connected and reinforced by fixing rod 18. Rotating bolt 2 19 can adjust the tightness of fixing rod 18 and fixing plate 7 to ensure the structural stability of fixing plate 7. The gasket 20 on the top of support frame 3 plays a buffering and protective role to prevent damage to the surface of support frame 3 when bolt 3 21 is tightened. By rotating bolt 3 21, other components can be firmly installed on the top of support frame 3. At the same time, the installation position and tightness of the components can be adjusted to make the connection of all parts of the device tight and reasonable, ensuring the normal operation of the roller clamping device for adding inkjet printing to the offset printing machine.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A wear-resistant block 22 is fixedly connected to the bottom of the outer wall of the motor 4. A buffer pad 23 is fixedly connected to the bottom of the outer wall of the wear-resistant block 22. An insertion hole 24 is installed on the top of the outer wall of the sprayer 15. An exhaust hole 25 is opened on the top of the outer wall of the sprayer 15. A throttle 27 is fixedly connected to the top of the outer wall of the two threaded rods 12. Foot supports 26 are fixedly connected to the bottom left and right sides of the fixed frame 1.

[0044] Specifically, the wear-resistant block 22 and buffer pad 23 at the bottom of the motor 4 reduce frictional loss, while the buffer pad 23 acts as a shock absorber, reducing the impact of motor 4's vibration on the overall device and ensuring equipment stability. The socket 24 on the top of the sprayer 15 facilitates external power and data connection, while the exhaust port 25 can expel excess gas from the inside, ensuring normal coding operation. The throttle 27 is fixed to the top of the threaded rod 12, and the threaded rod 12 can be easily adjusted by rotating the throttle 27 to adjust the height of the lifting plate 13 and the rolling shaft 14 to meet different pressing requirements. The foot support 26 at the bottom of the fixed frame 1 provides stable support, ensuring the stability of the entire device during operation.

[0045] Working principle: Motor 4 serves as the power source, fixed to the front inner wall of the fixed frame 1. After motor 4 starts, its output end drives the first rotating wheel 5 to rotate, generating initial power. The first rotating wheel 5 is connected to the second rotating wheel 8 via belt 6, transmitting power to the second rotating wheel 8, causing the second rotating wheel 8 to rotate on the front outer wall of the front fixed plate 7. Due to the smoothness and elasticity of belt 6, it can effectively transmit power and reduce impact. The gear 9 fixed on the rear outer wall of the second rotating wheel 8 rotates synchronously with the second rotating wheel 8. The gear 9 is fixed to the front fixed plate 7. Gears 10, rotatably connected to the left and right sides of the outer wall of plate 7, mesh with each other. When gear 9 rotates, according to the gear meshing principle, it drives the two gears 10 to rotate synchronously and in opposite directions. Rollers 11, rotatably connected to the rear sides of the outer walls of the two gears 10, rotate under the drive of gears 10. The rotation of rollers 11 is used to move the offset printing material forward, providing power for material transport during the offset printing process and ensuring continuous and stable material transmission in the offset printing machine. Threaded rods 12 are threadedly connected to the top of the inner walls of multiple fixed plates 7, and rotate... The threaded rod 12 is threadedly connected to the fixed plate 7, and the lifting plate 13 is rotatably connected to the outer wall of the threaded rod 12. According to the principle of threaded transmission, the lifting plate 13 will move up and down along the axial direction of the threaded rod 12. The rolling shaft 14, which is rotatably connected to the adjacent side of the inner wall of the lifting plate 13, moves with the lifting plate 13, thereby adjusting the distance between the rolling shaft 14 and the roller 11. When it is necessary to press the offset printing material, the lifting plate 13 is lowered by rotating the threaded rod 12, which drives the rolling shaft 14 closer to the roller 11. Pressure is applied to the offset printing material located between the two to ensure close contact between the material and the printing plate during the offset printing process, thereby improving the offset printing quality. The spraying machine 15 is set on the left side of the outer wall of the roller 14. During the rotation of the roller 14, the spraying machine 15 rotates with the roller 14. When the offset printing material passes between the roller 14 and the roller 11, the spraying machine 15 can perform inkjet printing operation on the offset printing material according to the preset program and instructions, thereby completing the inkjet printing function at the same time as offset printing, realizing the purpose of adding inkjet printing to the offset printing machine.

[0046] The electric actuator 201 is fixed to the right side of the inner wall of the fixed frame 1. When the system detects the need for correction, the electric actuator 201 is activated and outputs a linear thrust. This thrust is transmitted to the ratchet groove 202, which is fixedly connected to it, pushing the ratchet groove 202 to move in a set direction, providing initial power for correction. The turntable 203 is rotatably connected to the middle of the inner wall of the ratchet groove 202, and the pawl 205 is rotatably connected to one side of the inner wall of the turntable 203. The spring plate 204 at the bottom provides corrective support for the pawl 205, ensuring that it always maintains a meshing tendency with the inner wall of the ratchet groove 202. When the ratchet groove 202 moves under the action of the electric actuator 201, the pawl 205 interacts with the teeth of the ratchet groove 202, pushing the turntable 202 to move in a set direction. The turntable 203 rotates in one direction. The lever 206, fixed on one side of the outer wall of the turntable 203, swings as the turntable 203 rotates. During the swinging process, the lever 206 can push the part that needs to be corrected and change its direction of movement, thereby achieving correction. The adjusting rod 207, which is rotatably connected to the inner wall of the ratchet groove 202, can be used to adjust the position and angle of the ratchet groove 202 or change the rotation range of the turntable 203 to adapt to different correction needs and improve the applicability and flexibility of the correction mechanism 2. When the correction is completed, the electric push rod 201 stops working, and the spring plate 204 ensures that the pawl 205 remains engaged with the ratchet groove 202 to maintain the current position and prevent reverse deviation.
