Description

Technical Field

[0001] The present invention relates to the field of printing technology, and in particular to an ink printing smoothing mechanism and a smoothing method based on intelligent manufacturing. Background Art

[0002] Intelligent manufacturing is the product of the deep integration of new-generation information technology and advanced manufacturing technology. It runs through all aspects of manufacturing activities such as design, production, management, and service. Due to technological advances, intelligent manufacturing can be applied to printing and smoothing devices to make their work more efficient. Printing and smoothing devices based on intelligent manufacturing refer to equipment used in modern printing production lines to ensure the flatness and correct position of paper during the printing process, thereby improving printing quality and efficiency.

[0003] A common smoothing method involves pressing the printing material with a smoothing roller to flatten the wrinkled structure. However, due to the diverse characteristics and properties of the printing materials in the water-based printing process, including paper, plastic, and metal, relying solely on smoothing rollers to press and flatten the material is generally ineffective and has limited applicability. Furthermore, mechanical pressing often relies on the operator's experience to adjust the smoothing parameters, resulting in a delayed response and difficulty ensuring consistent processing. Furthermore, changes in ambient temperature and humidity significantly impact the material's flatness, making it prone to repeated wrinkling under conditions of large temperature differences. This approach is no longer able to meet the efficiency, precision, and intelligence requirements of modern intelligent manufacturing. Summary of the Invention

DETAILED DESCRIPTION

[0060] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0061] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0062] Example 1

[0063] As attached Figures 1 to 10 The ink printing smoothing mechanism based on intelligent manufacturing shown in the figure includes: a body 1:

[0066] The mechanical smoothing structure 301 and the gas smoothing structure 302 are configured to smooth the printing material;

[0067] The temperature compensation mechanism 303 is configured to control the surface temperature of the printing material within the range of T±ΔT, where T is a preset reference temperature and ΔT is an allowable fluctuation value;

[0068] The mode switching mechanism 4 is provided on the smoothing component 3 and includes:

[0069] A mechanical execution end 401 connected to the mechanical smoothing structure 301;

[0070] A gas execution end 402 connected to the gas smoothing structure 302;

[0071] The switching control component 403 is configured to control the working mode switching of the mechanical execution end 401 and the gas execution end 402 according to the data information detected by the feed detection unit 2, so that the mechanical smoothing structure 301 and / or the gas smoothing structure 302 act on the printing material.

[0072] Wherein: the machine body 1 is located at the feeding end of the ink printing device as a whole, and is used to smooth the printing material. The smoothed printing material is transported to the printing device for printing. The machine body 1 includes a frame and a base structure. The base structure is used to support and fix the frame. A walking structure is provided at the bottom of the base structure. The walking structure includes a universal wheel group and a locking device. The locking device is used to lock the rolling of the universal wheel group, thereby locking the position of the frame:

[0073] The feed detection unit 2 is arranged on the frame, located on the feed side of the ink printing device. The printing material is conveyed by the conveyor belt of the printing device. The feed detection unit 2 includes a spectral imaging sensor 201, a camera 202, an ultrasonic thickness monitoring instrument, a non-contact electrostatic sensor, a computing terminal and a self-cleaning protection system. The spectral imaging sensor 201 is used to analyze the material composition, detect the chemical composition of the ink, substrate and coating, identify invisible pollution, glue residue and other non-visible defects, monitor the process status such as dryness and oxidation degree, and the camera 202 is used to detect physical defects on the surface of the printing material (such as scratches, burrs, wrinkles, etc.), and monitor the feeding speed and position to avoid material deviation, jamming, etc.; the ultrasonic thickness monitoring instrument is used to detect internal defects such as delamination and bubbles; the non-contact electrostatic sensor monitors the surface static distribution in real time to prevent dust pollution of the printing material, thereby affecting the printing effect; the computing terminal is configured to communicate and interact with the above-mentioned electronic structure, can control the above-mentioned structure, and store and record the control records and interaction data for personnel to view; the self-cleaning protection system is used to remove dust from the surface of the sensor and camera 202 to avoid affecting the normal operation of the structure.

[0074] The smoothing assembly 3 can smooth the printing material, including a mechanical smoothing structure 301, a gas smoothing structure 302, a temperature compensation mechanism 303, and an ultrasonic smoothing structure (auxiliary). The mechanical smoothing structure 301 is a common structure, including a smoothing roller 308, an extension structure 309, and a drive motor 310. The number of smoothing rollers 308 is set to multiple groups, which can improve the smoothing and pressing effect on the printing material. The extension structure 309 can be a telescopic rod or a telescopic plate, which adjusts the distance between adjacent smoothing rollers 308 to better press and smooth. The drive motor 310 can be a servo motor or a stepper motor, which drives the smoothing roller 308 to rotate. The drive motor 310 is built-in with a control system to control the start-stop, speed, and direction of the smoothing roller 308;

[0075] The gas smoothing structure 302 is one of the core components of the ink printing smoothing mechanism, which processes the material surface through the cooperation of the air flow nozzle 311, the gas supply structure 312, and the angle adjusting device 313. The air flow nozzle 311 is arranged in multiple groups in an array, and the connection pipe is arranged between the air flow nozzles 311. The angle adjusting device 313 is arranged between the connection pipe and the air flow nozzle 311. The air flow nozzle 311 can dynamically adjust the coverage range according to the width of the printing material. The gas supply structure 312 provides stable gas flow, forming a laminar gas curtain at the nozzle outlet, effectively eliminating the microscopic wrinkles on the material surface without mechanical friction. The gas supply structure 312 includes a gas pump, a gas cavity structure, and a check valve. The gas pump is used to deliver gas to the gas cavity structure. The gas cavity structure is used for gas to stay and is transported to the air flow nozzle 311 through the delivery pipe. The check valve is used to control the gas flow. The angle adjusting device 313 drives the nozzle to deflect within a certain range through a micro-step motor, so that the gas flow impacts the material surface at the best incident angle, ensuring the smoothing effect and avoiding material displacement. This structure cooperates with the gas heating structure 306 in the temperature compensation mechanism 303 to control the gas flow temperature within the range of T±ΔT, avoiding material shrinkage and deformation caused by temperature difference;

[0076] The temperature compensation mechanism 303, the core temperature control module of the water-based inkjet printing and smoothing system, precisely manages the surface temperature of the printing material through a highly integrated closed-loop control system. Composed of a temperature measurement structure 304, a semiconductor cooling element 305, a gas heating element 306, and a controller 307, the mechanism ensures that the material temperature remains stable within a preset reference temperature range of T±ΔT through dynamic temperature measurement and feedback control. The temperature measurement structure 304 monitors the surface temperature distribution of the printing material in real time and transmits this multi-dimensional temperature data to the controller 307 after fusing it. The controller 307 dynamically calculates a temperature compensation strategy based on preset process parameters. When a localized temperature anomaly is detected, the compensation mechanism is immediately triggered. For example, if a localized overtemperature is detected, the semiconductor cooling element 305 is synchronously activated to rapidly cool the smoothing roller 308. Simultaneously, the output temperature of the gas heating structure 306 is precisely adjusted to ensure that the airflow nozzle 311 emits a temperature-compensating airflow. This bidirectional heat and cold regulation mechanism effectively addresses various temperature disturbances. This mechanism realizes intelligent data linkage with the computing terminal of the feed detection unit 2, and can automatically identify different material types (such as paper, plastic film, etc.) and match the optimal temperature control parameters, effectively avoiding quality defects such as material curling and coating peeling caused by thermal stress, and providing reliable temperature guarantee for high-precision ink printing;

[0077] The ultrasonic smoothing structure serves as an auxiliary roller and is arranged between adjacent smoothing rollers 308. The number of smoothing rollers is installed according to specific application needs. The auxiliary roller and the smoothing roller 308 are fixed by a detachable connection, which is convenient for disassembly and assembly. The ultrasonic smoothing structure is suitable for high-precision manufacturing scenarios and can be installed as needed.

[0078] The mode switching mechanism 4 serves as the core control unit of the intelligent printing system, realizing precise adaptive processing of the printing material. The mechanical execution end 401 serves as the driving control unit of the mechanical smoothing structure 301, and is composed of a first sliding block 408, a translation bracket 409 and a pressure sensor 410. The first sliding block 408 cooperates with the X-axis slide rail 406 through a precision linear guide rail, and the motion repeatability positioning accuracy can reach ±0.01mm. The translation bracket 409 adopts a high-strength aluminum alloy frame with an internal integrated ball screw transmission mechanism. The vertical stroke adjustment range is 50-150mm (customizable), and it is equipped with an automatic lubrication system to ensure long-term operation stability. The pressure sensor 410 feeds back the smoothing pressure data to the central processor 405 in real time;

[0079] The gas actuator 402 is the positioning and adjustment unit for the gas smoothing structure 302 and includes a second slider 411, a support frame 412, and a position sensor 413. The second slider 411 is driven by a servo motor and can move at speeds of up to 0.5 m / s on the Z-axis slide 407. The support frame 412 is modularly designed to support the gas smoothing structure 302 and incorporates an integrated gas distributor that simultaneously controls the independent gas supply to multiple groups of airflow nozzles 311.

[0080] The switching control assembly 403 includes a slide structure 404, a central processor 405, a redundant safety locking mechanism, a material edge correction system, and an auxiliary lighting and observation system. The slide structure 404 is an overall T-shaped or cross-shaped structure, fixed to the frame by welding or detachable connections. The switching control assembly 403 serves as the core intelligent control unit of the entire smoothing mechanism, achieving precise mode switching and control through the coordinated cooperation of various subsystems. The overall structure of the slide structure 404 maintains high rigidity while being lightweight. The X-axis slide 406 and the Z-axis slide 407 are staggered to ensure that the mechanical actuator 401 and the gas actuator 402 slide independently without interfering with each other. The central processor 405 adopts a modular design and has powerful data processing capabilities. It achieves precise coordinated control of each actuator through optimized algorithms. The redundant safety locking mechanism adopts a dual electromagnetic and mechanical locking method and is equipped with a status self-check function to ensure safe and reliable operation of the equipment. The material edge correction system uses multi-sensor fusion technology to achieve intelligent identification and automatic adjustment of the material position, effectively preventing deviation. The auxiliary lighting and observation system integrates multi-spectral lighting and high-definition imaging technology to provide operators with clear observation conditions and support remote monitoring functions. Each subsystem is interconnected through an intelligent bus to achieve real-time data sharing and command synchronization, making the entire switching control process more accurate and efficient;

[0081] Switching Control Component 403 offers enhanced adaptability and reliability, meeting the smoothing requirements of diverse materials and process conditions, providing a strong guarantee for high-quality printing production. Its modular design simplifies maintenance, intelligent control improves operational efficiency, and multiple safety features ensure stable operation. Through the coordinated optimization of its subsystems, Switching Control Component 403 achieves fast, accurate, and secure mode switching, becoming the core control hub of the entire smoothing mechanism.

[0082] Example 2

[0083] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working methods. Figures 1 to 10 As shown, see the following description for details:

[0084] As a preferred embodiment, the switching control component 403 includes a slide structure 404 and a central processor 405, the slide structure 404 includes an X-axis slide rail 406 slidingly connected to the mechanical execution end 401 and a Z-axis slide rail 407 slidingly connected to the gas execution end 402, wherein the X-axis slide rail 406 is arranged perpendicular to the Z-axis slide rail 407, and the central processor 405 is used to receive the data transmitted by the feed detection unit 2 and control the mechanical execution end 401 and the gas execution end 402 to slide, so that the mechanical smoothing structure 301 and / or the gas smoothing structure 302 slide to the working area to smooth the printing material.

[0085] Furthermore, both the X-axis slide rail 406 and the Z-axis slide rail 407 are rod-shaped or plate-shaped structures, and are fixed by welding or threaded connection. A fixing frame is provided at the bottom of the Z-axis slide rail 407 to connect with the body 1, further improving the stability of the overall structure. The X-axis slide rail 406 slide rail portion is set in the direction of setting on both sides of the slide rail rod body, and the Z-axis slide rail 407 slide rail portion is set at the front end of the slide rail body. The front end refers to the end of the sliding direction of the X-axis slide rail 406. The purpose of such setting is to ensure that the mechanical smoothing structure 301 and the gas smoothing structure 302 slide independently and do not contact or collide with each other; the slide structure 404 has a built-in fault self-diagnosis system that can monitor parameters such as guide rail wear and motor temperature in real time; the central processor 405 adopts an industrial-grade multi-core ARM architecture and is equipped with a real-time operating system to ensure that the control cycle is ≤1ms.

[0086] The system integrates a deep learning algorithm, and by analyzing the multimodal data of the spectral imaging sensor 201 and the camera 202, it intelligently selects the optimal smoothing mode (pure mechanical / pure gas / mixed mode), thereby improving the smoothing effect of the printing material. For the convenience of description, the X / Z axis is divided into a rest area and an operating area. The rest area is the non-operating position (including the initial position and the area outside the operating area), and the operating area is the position where the printing material is smoothed by sliding. Among them, the pure mechanical mode means that the gas execution end 402 is in the rest area of ​​the Z-axis slide rail 407, and the mechanical execution end is in the rest area of ​​the Z-axis slide rail 407. The row end 401 slides into the working area of ​​the X-axis slide rail 406 to perform smoothing operations; in pure gas mode, the gas execution end 402 enters the working area of ​​the Z-axis slide rail 407, and the mechanical execution end 401 is located in the rest area of ​​the X-axis slide rail 406. As above, in the mixed mode, the mechanical execution end 401 and the gas execution end 402 both enter the working area by sliding to perform operations. However, it should be noted that in the mixed mode, the time for the two groups of execution ends to enter the working area can be simultaneous, mechanical first or gas first, and the specific operation situation is adjusted according to the information feedback from the central processor 405.

[0087] As a preferred embodiment, the mechanical execution end 401 includes a first sliding block 408, a translation bracket 409 and a pressure sensor 410, wherein the first sliding block 408 is slidably connected to the X-axis slide rail 406, and the translation bracket 409 is arranged on the side of the first sliding block 408 to be connected to the mechanical smoothing structure 301, wherein the translation bracket 409 can drive the mechanical smoothing structure 301 to move toward or away from the ground, and the pressure sensor 410 is used to monitor the contact pressure between the mechanical smoothing structure 301 and the printing material.

[0088] Furthermore, the translation bracket 409 is driven by a servo electric cylinder and equipped with a high-precision linear guide rail to achieve precise lifting and lowering of the mechanical smoothing structure 301 in the vertical direction; the pressure sensor 410 is a thin-film multi-dimensional force sensor, which monitors the pressing force of the mechanical smoothing structure 301 on the printing material in real time and feeds back to the central processor 405 to form a closed-loop control. The setting of the translation bracket 409 facilitates the mechanical smoothing structure 301 to accurately press the printing material, avoiding damage to the material due to excessive pressing distance or poor smoothing effect due to excessive pressing distance; the first sliding block 408 is integrated with a self-lubricating A slippery graphite copper sleeve enables smooth, low-noise sliding on the X-axis slide 406. The X-axis slide 406 is located on either side. The first sliding block 408 is a U-shaped structure with two sets of side edges slidingly connected to the slides on either side. This arrangement is intended to prevent contact and collision with the gas actuator 402 on the Z-axis slide 407, or to prevent it from causing any obstruction to its own or the other side's sliding. The mechanical actuator 401 is linked to the temperature compensation mechanism 303 via industrial Ethernet. When pressure is abnormal, it automatically adjusts the temperature of the semiconductor cooling plate 305 to prevent damage to the printing substrate. This structure enables intelligent and precise control of smoothing pressure, ensuring optimal smoothing results for printing substrates of varying materials.

[0089] As a preferred embodiment, the gas execution end 402 includes a second sliding block 411 and a support frame 412 connected thereto, the second sliding block 411 is slidably connected to the Z-axis slide rail 407, the support frame 412 is used to support the gas smoothing structure 302, and the Z-axis slide rail 407 and the X-axis slide rail 406 are provided with position sensors 413 for monitoring the positions of the second sliding block 411 and the first sliding block 408 respectively.

[0090] Furthermore, the gas execution end 402 is used to control the gas smoothing structure 302. The number of second sliding blocks 411 can be set in multiple groups, which are set at a certain distance from each other. The set distance will not affect the displacement of the support frame 412. The impact means that the support frame 412 can accurately reach the working area or non-working area. An auxiliary coupling rod is provided between the second sliding block 411 and the Z-axis slide rail 407, and the auxiliary coupling rod is slidably connected to the edge structure of the Z-axis slide rail 407. The number of auxiliary coupling rods can be set in multiple groups to improve the stability of the overall structure of the second sliding block 411 and the support frame 412. The support frame 412 is a U-shaped structure as a whole, and the horizontal side structure is connected to the second sliding block 411 as a coupling end. The two are fixed by welding or threaded connection. The side of the U-shaped structure is used to support and fix the gas smoothing structure 302.

The setting position is close to the end of the sliding direction of the two groups of slide rails. The purpose of such a setting is to be able to monitor the positioning status of the mechanical smoothing structure 301 and the gas smoothing structure 302. The positioning status means that the mechanical smoothing structure 301 reaches the predetermined position through horizontal sliding and the gas smoothing structure 302 reaches the predetermined position through vertical sliding, so as to smooth the printing material.

[0091] As a preferred embodiment, the slide structure 404 is arranged in a T-shape as a whole, and the Z-axis slide rail 407 and the X-axis slide rail 406 are respectively provided with a screw structure 414 and a buffer pad 415.

[0092] Furthermore, the screw structure 414 adopts a C3-level precision ball screw, which cooperates with a servo motor to achieve micron-level positioning. There are at least two groups of screw structures 414, one of which is set on the X-axis slide 406, and the remaining group is set on the Z-axis slide 407. The setting of the screw structure 414 can improve the sliding stability of the two groups of sliding blocks, thereby improving the stability of the overall device; heavy-duty cross roller bearings are used at the intersection of the X-axis slide 406 and the Z-axis slide 407 to ensure the stability of the T-shaped structure under high-speed reciprocating motion; the buffer pad 415 is a polyurethane-metal composite damping structure with a built-in acceleration sensor to achieve collision warning. When an abnormal impact is detected, the braking system is immediately triggered to avoid damage to the structure caused by excessive contact impact; the central processor 405 collects data from each axis position sensor 413 in real time through the bus, and uses a feedforward compensation algorithm to eliminate mechanical lag, so that the switching time between the mechanical smoothing structure 301 and the gas smoothing structure 302 is controlled within 0.3 seconds.

The setting of the semiconductor cooling plate 305 facilitates the adjustment of the pressing temperature of the smoothing roller 308. The purpose of adjusting the temperature is to prevent certain materials from being affected by the ambient temperature, making wrinkles difficult to remove or re-forming after removal. The gas heating structure 306 uses a PID-controlled ceramic heating element, which cooperates with a gas flow meter to achieve on-demand heating, ensuring that the output gas temperature uniformity deviation is ≤1°C. The controller 307 dynamically optimizes the temperature control strategy based on the material characteristics, movement speed and other parameters obtained by the feed detection unit 2, so that the surface temperature of the printing material is always stable within the range of T±ΔT. The above settings achieve intelligent temperature control during the printing process, effectively avoiding material deformation and printing quality problems caused by temperature fluctuations.

Through the above setting, intelligent gradient pressure control can be realized, and the material deformation problem caused by traditional rigid roller pressing can be solved.

The camera 202 is used to capture the position and movement trajectory of the printing material in real time.

[0100] Furthermore, the spectral imaging sensor 201 utilizes a hyperspectral imaging system with an operating wavelength range of 400-2500nm. This system simultaneously captures the physical properties (such as wrinkles and scratches) and chemical characteristics (such as coating composition distribution) of the printing material surface, providing data support for subsequent precise smoothing. Multiple cameras 202 are arranged in groups, spaced apart at regular intervals. Using a circular array LED fill-light system, the cameras 202 automatically adapt to the reflective properties of different materials, eliminating the overexposure and underexposure issues encountered in traditional inspections.
