Description

Technical Field

[0001] This invention relates to the field of green printing plate-making equipment technology, specifically to a plate-making machine adjustment device for green printing. Background Technology

[0002] A plate-making machine is a device used in the printing industry to make printing plates. Its core function is to convert electronic design drafts or graphic information into physical plates that can be printed. The plate-making machine is a key link in the printing process, which directly affects the quality and efficiency of the final printed products.

[0003] The adjustment device of the plate-making machine refers to the parameter adjustment of different components of the equipment during the plate-making process. Its core function is to ensure the accuracy, stability and consistency of the plate-making process, which can directly affect the quality of the final printing plate.

[0004] However, the existing plate-making machine adjustment device for green printing has the following shortcomings: Existing plate-making machine adjustment devices, such as traditional mechanical clamps, typically have a fixed clamping force or require manual adjustment. This makes them unsuitable for the physical properties of different plate materials. Applying excessive force to soft plate materials can lead to deformation and scratches, while providing insufficient clamping force to thick and hard plate materials can cause slippage or detachment. Furthermore, traditional clamping heads often have fixed shapes and contact methods, which cannot flexibly adapt to plates of different sizes, shapes, or textures. This distribution of contact points can lead to localized stress concentration, causing localized deformation of the plate material or clamping failure.

[0005] Therefore, we propose a plate-making machine adjustment device for green printing to address the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a plate-making machine adjustment device for green printing. By setting a magnetorheological adaptive clamping component, the magnetorheological fluid can rapidly change from a liquid to a solid state under the action of a magnetic field, with a response time as low as milliseconds. The magnitude and distribution of the clamping force can be controlled in real time by adjusting the current. The circumferentially distributed contact points and vertical planar contact points on the contact surface of the clamping head, combined with the vortex chamber structure design, can adapt to plates of different shapes, thicknesses or surface textures, thereby solving the problems mentioned in the background art.

A baffle is slidably connected between the two electric guide rails. A fixing member is bolted to one side of the outer wall of the baffle. A laser assembly is movably installed between the inner walls of the housing. A printing plate is placed between the baffle and the base plate.

[0009] Preferably, the magnetorheological adaptive clamping assembly further includes a cylinder, a connector is fixedly connected to the bottom of the cylinder, a support plate is bolted to one side of the outer wall of the connector, a slide rail is fixedly connected to one side of the outer wall of the support plate, and a sliding plate is movably connected between the inner surfaces of the slide rail.

[0011] Preferably, a solid rod is movably inserted between the inner surfaces of the slide rod, a clamping head is fixedly connected to one side of the outer wall of the solid rod, four springs are elastically connected between the outer wall of the slide rod and the outer wall of the clamping head, and four connecting parts are bolted to the outer surface of the clamping head.

[0012] Preferably, four sets of brackets are connected between the outer walls of the four connecting members, and four electromagnetic coils are inserted and connected between the outer walls of the four sets of brackets. One side of the outer wall of the clamping head is inserted and connected to a first magnetorheological fluid storage chamber.

[0013] Preferably, one side of the outer wall of the clamping head is connected to the outer surface of a set of second magnetorheological fluid storage chambers, a position sensor is fixedly installed on one side of the outer wall of the corner plate, and one side of the outer wall of the connector is bolted to one side of the outer wall of the fixing member.

[0014] Preferably, the temperature control component further includes two liquid cooling pipes and a circulation pump. Both liquid cooling pipes are connected to three annular pipes. The outer surface of one of the annular pipes is connected to two connecting pipes. One end of the outer wall of the two connecting pipes is connected to an outlet pipe and an inlet pipe, respectively. A temperature sensor is connected to the outer surface of the inlet pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by setting up a magnetorheological adaptive clamping component, the magnetorheological fluid can rapidly change from a liquid to a solid state under the action of a magnetic field, with a response time as low as milliseconds. The magnitude and distribution of the clamping force can be controlled in real time by adjusting the current. The circumferentially distributed contact points and vertical planar contact points on the contact surface of the clamping head, combined with the vortex chamber structure design, can adapt to plates of different shapes, thicknesses, or surface textures, avoiding excessive clamping that could lead to plate deformation or damage. At the same time, the circumferentially distributed magnetorheological contact points can achieve uniform force distribution in all directions, avoiding local stress concentration and thus improving clamping stability. This adaptive clamping method reduces the need for manual adjustment of clamping position and force, reduces the complexity of operation, and thus improves the level of automation.

[0018] 2. In this invention, by setting a temperature control component, the magnetorheological fluid is composed of micron-sized magnetic particles suspended in carrier oil. In a static state, the particles are prone to aggregation or sedimentation due to gravity or electrostatic force, which will lead to fluid inhomogeneity. The shear force and kinetic energy generated by the high-frequency vibration of the ultrasonic transducer continuously disperse the particles and maintain a uniform suspension state. When the magnetorheological fluid is under high shear stress or high-frequency vibration, it will generate heat through friction, causing the phase change material embedded in the vortex chamber to absorb heat and store thermal energy. When the temperature exceeds a predetermined threshold, the micro liquid cooling pipe is activated, and the circulating coolant carries away the heat released by the phase change material.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In embodiments of the present invention, please refer to the appendix. Figure 1 - Appendix Figure 3 As shown, the present invention provides a technical solution: a plate-making machine adjustment device for green printing, including four support feet 100, a magnetorheological adaptive clamping assembly 900, and a temperature control assembly 110. The four support feet 100 can provide sufficient support for the magnetorheological adaptive clamping assembly 900 and the temperature control assembly 110. The temperature control assembly 110 is installed on one side of the outer wall of the magnetorheological adaptive clamping assembly 900. Four sets of magnetorheological adaptive clamping assemblies 900 are equidistantly arranged on the top of the four support feet 100, and both the magnetorheological adaptive clamping assembly 900 and the temperature control assembly 110 are installed on the top of the four support feet 100.

[0023] Specifically: First, determine the exact installation positions of the four support legs 100. Then, fix the four support legs 100 to the ground. After fixing the four support legs 100 to the ground, when plate making is required, the operator manually places the plate material 140 between the baffle 700 and the base plate 500. At this time, the magnetorheological fluid adaptive clamping assembly 900 is activated via an external power supply. The plate-making machine control system 400, based on the position of the plate material 140, sends a command to energize the four electromagnetic coils 914, generating a strong magnetic field. The first magnetorheological fluid storage chamber 915 and a set of second magnetorheological fluids... The magnetic particles inside the storage chamber 916 rapidly arrange themselves in a chain in the magnetic field. At this time, the magnetorheological fluid hardens instantly and adheres tightly to the surface of the plate 140. Meanwhile, if an abnormal vibration frequency is detected during the clamping process, the ultrasonic transducer 111 increases the ultrasonic power to the preset upper limit and redistributes the particles evenly. During clamping, the magnetorheological fluid generates heat due to shearing. At this time, the temperature control component 110 comes into play, and the coolant circulates inside the three annular pipes 112 to directly cool the magnetorheological fluid storage chamber 916 and the magnetorheological fluid material inside until the temperature drops back to a safe range.

[0024] In some embodiments, according to Figures 1-8As shown, the magnetorheological adaptive clamping assembly 900 includes four electromagnetic coils 914, a set of first magnetorheological fluid storage chambers 915, and a set of second magnetorheological fluid storage chambers 916. The four electromagnetic coils 914 are used to generate a directional magnetic field. The set of first magnetorheological fluid storage chambers 915 are arranged in a circular array to form a transverse contact point, and the set of second magnetorheological fluid storage chambers 916 are arranged in a ring-shaped circular array to form a planar contact point. Both the set of first magnetorheological fluid storage chambers 915 and the set of second magnetorheological fluid storage chambers 916 are filled with magnetorheological fluid.

[0025] The magnetorheological adaptive clamping assembly 900 also includes a cylinder 901, with a connector 902 fixedly connected to the bottom of the cylinder 901. A support plate 903 is bolted to one side of the outer wall of the connector 902. A slide rail 904 is fixedly connected to one side of the outer wall of the support plate 903. A sliding plate 905 is movably connected between the inner surfaces of the slide rail 904.

[0026] Angle plate 907 is bolted to one side of the outer wall of the slide plate 905. A connecting rod 906 is movably connected to the shaft of the cylinder 901. The connecting rod 906 and the slide plate 905 are connected by bolts. A sliding rod 908 is fixedly connected to one side of the outer wall of the angle plate 907, and the sliding rod 908 has a hollow structure inside.

[0027] A solid rod 909 is movably inserted between the inner surfaces of the slide rod 908. A clamping head 911 is fixedly connected to one side of the outer wall of the solid rod 909. Four springs 910 are elastically connected between the outer wall of the slide rod 908 and the outer wall of the clamping head 911. Four connecting parts 912 are bolted to the outer surface of the clamping head 911.

[0028] Four sets of brackets 913 are connected between the outer walls of the four connectors 912. Four electromagnetic coils 914 are inserted and connected between the outer walls of the four sets of brackets 913. One side of the outer wall of the clamping head 911 is inserted and connected to a first magnetorheological fluid storage chamber 915.

[0029] One side of the outer wall of the clamping head 911 is connected to the outer surface of a set of second magnetorheological fluid storage chambers 916. A position sensor 917 is fixedly installed on one side of the outer wall of the corner plate 907. One side of the outer wall of the connector 902 is bolted to one side of the outer wall of the fixing member 800.

[0030] The overall effect of this embodiment is as follows: By pre-setting the above components, a complete magnetorheological adaptive clamping assembly 900 is formed. First, the plate-making machine is turned on by operating button 300. At this time, the magnetorheological adaptive clamping assembly 900 performs a self-test. Next, the operator manually places the plate material 140 to be made between the baffle 700 and the base plate 500, and the magnetorheological adaptive clamping assembly 900 is raised or lowered to the height of the plate material 140 by the electric guide rail 600. After the plate material 140 is safely placed, the plate-making machine control system 400 sends a command according to the position of the plate material 140, which activates cylinder 901. The transmission shaft of cylinder 901 is vertical and connected to connecting rod 906, converting the vertical movement into the horizontal movement of connecting rod 906. The linear motion is connected by the connecting rod 906 and the corner plate 907. The corner plate 907 moves the clamping head 911 away from the plate 140 along the lateral direction of the slide rail 904. When the corner plate 907 slides laterally, the clamping head 911 is elastically connected to the spring 910 through the slide rod 908, ensuring that the end of the clamping head 911 can automatically adapt to the slight unevenness of the surface of the plate 140 and make the clamping head 911 fully contact the plate 140. Before this, the first magnetorheological fluid storage chamber 915 and a set of second magnetorheological fluid storage chambers at one end of the clamping head 911 have been pre-filled with magnetorheological fluid and are in a liquid state. The magnetorheological fluid inside the clamping head 911 is not activated, and only the preload of the spring 910 provides slight contact pressure. When the clamping head 911 approaches the workpiece surface, the electromagnetic coil 914 is energized, generating a strong magnetic field. Magnetic particles rapidly arrange themselves in a chain within the magnetic field, and the magnetorheological fluid instantly changes from a liquid to a near-solid state, forming vertical planar contact points that tightly adhere to the workpiece surface. Furthermore, by adjusting the current intensity of the electromagnetic coil 914, the control system 400 can dynamically adjust the clamping force. A position sensor 917 installed on the outer surface of the clamping head 911 provides real-time distance data when the clamping head 911 approaches the plate 140. The control system 400 can precisely control when the cylinder 901 stops moving, preventing damage to the plate 140 due to excessive pressure. Simultaneously, a pressure sensor embedded inside the clamping head 911 provides real-time pressure data feedback. With the help of the control system 400, the compressive strength threshold of the plate 140 is ensured to be not exceeded. At this time, the magnetorheological adaptive clamping assembly 900 completes the clamping work of the plate 140. Then, by activating the laser assembly 130, the plate making process of the plate 140 begins. After the plate making is completed, the operator turns off the laser assembly 130 through the control system 400. At this time, the control system 400 cuts off the power supply to the electromagnetic coil 914, the magnetorheological fluid returns to a liquid state, the contact points are de-hardened, and the clamping force is successfully released. By activating the cylinder 901, the vertical motion is converted into the linear motion of the transverse connecting rod 906. The connecting rod 906 is connected to the corner plate 907, which in turn drives the clamping head 911 to move the plate 140 in the opposite direction along the transverse direction of the slide rail 904.At this point, the worker can manually remove plate 140, thus completing the entire clamping process. For the adaptive process of thin aluminum sheets, when the operator places the thin aluminum sheet between the baffle 700 and the base plate 500, the position sensor 917 first detects the edge position of the sheet and feeds it back to the plate-making machine control system 400 in real time. The control system 400 matches the thickness parameter with the built-in material database and calls the 80-120MPa compressive strength characteristic benchmark value of the aluminum sheet. This benchmark value is calculated according to the principle that the safe clamping force is equal to the compressive strength multiplied by the contact area multiplied by a 50% safety factor. At this time, the control system 400 sends a command to pass a 1.2A current through the four electromagnetic coils 914 to generate a 0.3T magnetic field. The magnetorheological fluid in the first magnetorheological fluid storage chamber 915 and the second magnetorheological fluid storage chamber 916 initially hardens into a semi-solid state. The pre-tightening force of the spring 910 then... The clamping head 911 initially contacts the surface of the sheet material. The pressure sensor embedded in the clamping head 911 monitors the contact pressure in real time. When the system detects that the pressure exceeds the upper limit of the reference pressure, it immediately feeds back to the control system 400. The control system precisely reduces the current of the electromagnetic coil 914 to 0.8A and weakens the magnetic field strength to 0.2T, which reduces the hardening degree of the magnetorheological fluid. The closed-loop monitoring of the pressure sensor ensures that the pressure is stable within the reference pressure range. At the same time, the preload of the spring 910 provides double protection. When the aluminum sheet material generates high-frequency micro-vibration due to its thinness, the ultrasonic transducer 111 starts the 30W low-power mode to disperse the particles. The control system simultaneously adjusts the current from 0.8A to 0.9A, keeping the magnetorheological fluid in a semi-hardened elastic state. This absorbs vibration energy and maintains a stable clamping force through pressure closed-loop control. For the adaptive clamping process of thick cardboard, when the thick corrugated cardboard is placed between the baffle 700 and the base plate 500, the position sensor 917 detects an increase in the thickness of the clamped board. At this time, the control system 400 identifies it as a high-thickness material and calls the corrugated cardboard characteristic parameter of compressive strength 2-4MPa. This benchmark value is calculated according to the principle that the safe clamping force equals the compressive strength multiplied by the contact area multiplied by a 50% safety factor. The control system 400 sends a control command to cause the electromagnetic coil 914 to pass a 2.5A current to generate a 0.6T strong magnetic field. The first magnetorheological fluid storage chamber 915 and The second magnetorheological fluid storage chamber 916 is simultaneously and completely hardened to form a rigid contact surface. Due to the greater shearing force required for clamping the thick corrugated cardboard, the temperature of the magnetorheological fluid rises rapidly. At this time, the temperature control component 110 starts the cooling mode, increasing the flow rate of the coolant in the annular pipe 112 from 0.5 m / s to 1.2 m / s. At the same time, the control system 400 finely adjusts the current to 2.6A, compensates for the 3% hardness loss by 5% magnetic field strength, and ensures that the temperature of the magnetorheological fluid is stable at the standard temperature through real-time monitoring by the temperature sensor 117, thus ensuring clamping rigidity and avoiding local crushing.

[0031] The magnetorheological adaptive clamping component 900 allows the magnetorheological fluid to rapidly change from a liquid to a solid state under the influence of a magnetic field, with a response time as low as milliseconds. The magnitude and distribution of the clamping force can be controlled in real time by adjusting the current. The circumferentially distributed contact points and vertical planar contact points on the contact surface of the clamping head 911, combined with the vortex chamber structure design, can adapt to plates 140 with different shapes, thicknesses, or surface textures, avoiding over-clamping that could cause deformation or damage to the plate 140. At the same time, the circumferentially distributed magnetorheological contact points can achieve uniform force distribution from all directions, avoiding local stress concentration and thus improving clamping stability. This adaptive clamping method reduces the need for manual adjustment of clamping position and force, reduces the complexity of operation, and thus improves the level of automation.

[0032] according to Figures 1-2 as well as Figures 8-11 As shown, the temperature control component 110 includes a set of ultrasonic transducers 111, which are used to generate high-frequency vibrations. The outer surface of the set of ultrasonic transducers 111 is connected to three annular pipes 112, which are used to circulate coolant and remove heat.

[0033] The temperature control component 110 also includes two liquid cooling pipes 113 and a circulation pump 118. Both liquid cooling pipes 113 are connected to three annular pipes 112. The outer surface of one of the annular pipes 112 is connected to two connecting pipes 114. One end of the outer wall of the two connecting pipes 114 is connected to the liquid outlet pipe 115 and the liquid inlet pipe 116, respectively. The outer surface of the liquid inlet pipe 116 is connected to a temperature sensor 117.

[0034] The inlet and outlet of the circulating pump 118 are connected to the outlet pipe 115 and the inlet pipe 116, respectively. The top of the circulating pump 118 is connected to the delivery pipe 119, and the inlet of the delivery pipe 119 is connected to the storage tank 120.

[0035] The outer wall of the circulating pump 118 is bolted to one side of the outer wall of one set of brackets 913, and the top of one set of brackets 913 is bolted to the bottom of the storage tank 120.

[0036] The overall effect of this embodiment is as follows: The above-mentioned components form a complete temperature control assembly 110. Before the magnetorheological adaptive clamping assembly 900 clamps the plate 140, the magnetorheological fluid consists of micron-sized magnetic particles suspended in a carrier oil. In a static state, the particles are prone to aggregation or sedimentation due to gravity or electrostatic force, leading to fluid inhomogeneity. At this time, the control system 400 activates the ultrasonic transducer 111. Utilizing the high-frequency vibration of the ultrasonic transducer 111, the shear force and kinetic energy generated continuously disperse the particles, maintaining a uniform suspension state. The high-frequency vibration generates microbubbles in the liquid, creating directional flow and promoting the dispersion of magnetic particles. Through continuous vibration, the micron-sized magnetic particles in the magnetorheological fluid are uniformly suspended in the carrier oil. In the oil, a stable colloidal system is formed. During high-load operation, the magnetorheological fluid generates heat due to shear stress and friction. Even when the magnetorheological adaptive clamping assembly 900 finishes clamping the plate 140, the heat generated during this high-load operation continues. At this time, the circulation pump 118 is started. The circulation pump 118 draws the cooling liquid from the storage tank 120 through the liquid delivery pipe 119 and delivers the cooling liquid to the three annular pipes 112 through the liquid outlet pipe 115. The three annular pipes 112 circulate the cooling liquid to the circulation pump 118 through the liquid inlet pipe 116. The cooling liquid can fully absorb the heat released by the phase change material and remove some of the heat from the fluid. When the temperature drops to a safe range, the temperature control assembly 110 stops operating.

[0037] The temperature control component 110 is set up so that the magnetorheological fluid is composed of micron-sized magnetic particles suspended in the carrier oil. In a static state, the particles are prone to agglomeration or sedimentation due to gravity or electrostatic force, which will lead to fluid inhomogeneity. The shear force and kinetic energy generated by the high-frequency vibration of the ultrasonic transducer 111 continuously disperse the particles and maintain a uniform suspension state. When the magnetorheological fluid is under high shear stress or high-frequency vibration, it will generate heat through friction, causing the magnetorheological fluid in the first magnetorheological fluid storage chamber 915 and a set of second magnetorheological fluid storage chambers 916 to absorb heat and store thermal energy. When the temperature exceeds the predetermined threshold, the circulating coolant will carry away the heat released by the phase change material.

[0038] according to Figures 1-3 As shown, a housing 200 is fixedly connected to the top of the four support legs 100. An operation button 300 is installed on one side of the outer wall of the housing 200. A control system 400 is connected to one side of the outer wall of the housing 200. A base plate 500 is fixedly connected between the inner walls of the housing 200. Two electric guide rails 600 are installed on the inner wall of the housing 200. A baffle 700 is slidably connected between the two electric guide rails 600. A fastener 800 is bolted to one side of the outer wall of the baffle 700. A laser assembly 130 is movably installed between the inner walls of the housing 200. A plate 140 is placed between the baffle 700 and the base plate 500.

[0039] The overall effect of this embodiment is as follows: First, the specific installation positions of the four support legs 100 are determined. Then, the four support legs 100 are fixedly connected to the ground. After the four support legs 100 are fixed to the ground, the housing 200 is fixedly connected to the top of the four support legs 100. An operation button 300 is installed on one side of the outer wall of the housing 200. The operator can control the start and stop of the plate-making machine through the operation button 300. A control system 400 is connected to one side of the outer wall of the housing 200. The control system 400 can control the parameters of each system of the plate-making machine and can monitor the data of each sensor in real time, accurately reflecting the data on the display screen. The operator can control the parameters of each sensor and various devices through the control system 400. When plate-making is required for the plate material 140, the operator manually places the plate material 140 between the baffle 700 and the base plate 500, and the magnetohydrodynamic adaptive clamping assembly 900 is raised or lowered to the height of the plate material 140 by the electric guide rail 600. After the plate material 140 is safely placed, the magnetohydrodynamic system is activated by an external power supply. The adaptive clamping assembly 900 is activated. At this time, the plate-making machine control system 400, based on the position of the plate 140, sends a command to energize four electromagnetic coils 914, generating a strong magnetic field. Magnetic particles inside the first magnetorheological fluid storage chamber 915 and a set of second magnetorheological fluid storage chambers 916 rapidly arrange themselves in a chain within the magnetic field. The magnetorheological fluid instantly hardens, thus tightly adhering to the surface of the plate 140. After adhering, the control system 400 activates the laser assembly 130 to perform plate-making on the plate 140. After plate-making is completed, the operator... The operator shuts down the laser assembly 130 via the control system 400. At this time, the control system 400 cuts off the power to the electromagnetic coil 914, the magnetorheological fluid returns to a liquid state, the contact points are de-hardened, and the clamping force is successfully released. By starting the cylinder 901, the vertical motion is converted into the linear motion of the transverse connecting rod 906. The connecting rod 906 is connected to the corner plate 907, which in turn drives the clamping head 911 to move in the opposite direction of the plate 140 along the transverse direction of the slide rail 904. At this time, the operator can manually remove the plate 140, thus completing the entire clamping operation.
