Its principle is to use a scraper to print ink from the image area pre-made on the screen plate onto the substrate. The equipment to achieve this purpose is a screen printing equipment. Its core components include a scraper arm assembly and a mesh arm assembly. The two need to work together to realize the screen printing process: the mesh arm assembly fixes the screen through a clamping mechanism, and the scraper arm assembly drives the scraper to scrape the ink on the surface of the screen at a specific angle and pressure to make it evenly penetrate into the substrate. The relative spatial position and dynamic balance relationship between the two directly affect the printing quality / effect.

On the one hand, the traditional structure can only adapt to components of specific specifications, resulting in the need for independent development of dedicated receiving bodies for different configurations of equipment, increasing R&D costs and maintenance complexity. On the other hand, the existing mechanism lacks dynamic adjustment capabilities, and cannot quickly release the screen for cleaning or replacement through the opening action, nor can it accurately maintain the rigid coupling relationship between the scraper arm and the screen arm through the tightening action, affecting printing stability.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-7 , a universal mechanism for receiving screen printing equipment components, including a support frame 100, a linkage module 101 and a limit adjustment module 102; The support frame 100 is composed of a wing plate member 103, wherein the upper front end of the wing plate member 103 is provided with a preset interface area 104, and the preset interface area 104 is provided with a positioning feature 105 adapted to the scraper arm assembly; The linkage module 101 is installed below the preset interface area 104, and includes a mesh arm connector 107 rotatably connected to the wing plate, and a bridge member 108 is extended and installed on the mesh arm connector 107; The limit adjustment module 102 is integrated in the middle of the wing plate 103, and includes a limit assembly 109 and a drive assembly 110. The limit assembly 109 includes a cam assembly 111. The cam assembly 111 cooperates with the bridge member 108 to control the opening and tightening action between the scraper arm assembly and the net arm assembly. The drive assembly 110 includes an external power source or a manual operation unit for driving the cam assembly 111 to rotate; A standardized interface area is preset on the upper part of the wing plate 103 of the support frame 100. By integrating positioning holes 118, card slots, magnetic adsorption or welding extension structures and other positioning features 105, rapid physical locking and posture calibration of scraper arm components of various specifications are achieved. There is no need to develop independent support structures for different components. It is compatible with scraper systems of different brands and sizes, greatly reducing the equipment modification R&D cost and parts inventory pressure; The linkage module 101 and the limit adjustment module 102 work together, and utilize the precise contour curve of the cam assembly 111 and the lever transmission mechanism of the bridge member 108 to convert the rotational motion of the drive assembly 110 into a controllable linear displacement between the scraper arm assembly and the screen arm assembly. The clamping force between the two can be precisely adjusted through the cam lift to maintain a rigid connection during the printing process to avoid relative displacement caused by vibration or load fluctuation. The cam return stroke can also trigger a quick separation action to quickly separate the screen from the scraper system when not in operation, thereby simplifying the cleaning and replacement process and reducing downtime. The drive assembly 110 adopts a split interface design, allowing an external power source (such as a servo motor or a cylinder) or a manual operation unit (such as a handwheel) to be connected through a standardized coupling or a quick-release structure, which not only meets the precise control requirements of the automated production line for electric drive, but also retains the flexibility of manual intervention; at the same time, the eccentric layout of the cam assembly 111 and the optimized arm design of the bridge 108 can achieve a torque amplification effect in a limited space, ensuring reliable execution of the action under high load conditions; In addition, the modular design frees up the layout of the equipment, and can adapt to the asymmetric rack structure or customized printing path planning required for special-shaped substrates, breaking through the limitation that traditional screen printing equipment is only suitable for small-scale regular workpieces. The technical solution of the present invention effectively improves the compatibility and dynamic adjustment capability of screen printing equipment components through modular structural design. The preset interface area 104 and positioning feature 105 of the support frame 100 realize rapid adaptation to diversified scraper arm components, reducing the need for development of special receiving bodies; the synergistic effect of the linkage module 101 and the limit adjustment module 102 dynamically controls the rigid coupling relationship between the scraper arm and the screen arm through the cam assembly 111, while ensuring printing quality and supporting rapid opening action to complete screen cleaning / replacement, and the standardized interface design of the integrated drive assembly 110 is compatible with electric / pneumatic / manual operation modes, and can achieve high torque output in a compact space, ultimately breaking through the limitations of traditional matching structures, significantly reducing equipment R&D and maintenance costs and expanding the adaptability to special-shaped substrate scenarios.

[0019] In the embodiment of the present invention, the wing plate member 103 is rotatably connected with a steering adjustment member 115, which is installed on a workbench to adjust the steering of the wing plate member 103, and a rigid locking structure is provided on the steering adjustment member 115; The technical solution of the present invention realizes the multi-degree-of-freedom precise control of the support frame 100 by adding a steering adjustment member 115. The steering adjustment member 115 is rotatably connected to the wing member 103 and fixed to the workbench. The horizontal deflection angle of the wing member 103 can be adjusted to a specific angle based on different printing requirements, so as to flexibly adapt to the curved surface contour or asymmetric printing path of the special-shaped substrate, ensuring that the scraper and the screen always maintain the best contact posture; At the same time, the steering adjustment member 115 adopts an integrated design. The angle locking and releasing can be completed by a manual knob or an electric drive unit without the need for additional tools during operation, which significantly simplifies the equipment adjustment process and improves the repeatability of process parameters. The adjusted rigid locking mechanism effectively avoids the angle deviation caused by external force interference during operation, maintains the uniform distribution of printing pressure, and further enhances the stability of printing quality under complex working conditions. In one embodiment, the rigid locking structure comprises a bolt.

[0020] In the embodiment of the present invention, the upper front end of the wing plate 103 extends outward to form the preset interface area 104, and the preset interface area 104 is provided with a positioning hole 118 in the transverse direction. The extending direction of the positioning hole 118 is parallel to the installation axis of the scraper arm assembly, and is used to adapt to the bolt connection of scraper arm assemblies of different sizes; The technical solution of the present invention significantly improves the cross-size compatibility and installation quality of the scraper arm assembly by optimizing the structural layout of the preset interface area 104. The preset interface area 104 formed by the front end of the upper part of the wing plate 103 extending outward has multiple positioning holes 118 evenly distributed in the transverse direction, and the extension direction is strictly parallel to the installation axis of the scraper arm assembly, so that scraper arm assemblies of different sizes can be quickly aligned and locked along the axis direction of the positioning holes 118 by standard bolts, ensuring the spatial centering and angle consistency between the scraper system and the screen. This structural feature is compatible with the expansion requirements of multiple specifications of scraper arms from narrow to wide widths, avoiding interface reconstruction or adapter installation due to component size differences. It also reduces the assembly stress caused by angle deviation during installation through axial constraint design, thereby maintaining the stability of the scraper's motion trajectory. At the same time, the modular bolt connection mechanism simplifies the disassembly and assembly process, shortens equipment changeover time and improves maintenance efficiency.

[0021] In the embodiment of the present invention, the positioning feature 105 includes a guide groove and a clamping protrusion arranged in the preset interface area 104, the guide groove extends along the installation direction of the scraper arm assembly and matches the sliding part of the scraper arm assembly, and the clamping protrusion is distributed on both sides of the guide groove to limit the lateral deviation of the scraper arm assembly; The technical solution of the present invention significantly improves the installation quality and anti-deviating stability of the scraper arm assembly by strengthening the guiding and limiting functions of the positioning feature 105. The guide groove in the preset interface area 104 extends along the installation direction of the scraper arm assembly and forms a linear matching constraint with its sliding part, ensuring that the scraper system is accurately introduced along the preset path and maintaining the parallelism between the running path of the scraper system and the screen. The snap-in protrusions distributed on both sides of the guide groove effectively suppress the position deviation of the scraper arm assembly when it is subjected to lateral force through physical blocking, thereby avoiding scraper angle deviation caused by vibration or load fluctuation. At the same time, the combined positioning structure allows scraper arm assemblies of different models to be quickly embedded in the guide groove through the standardized sliding part and use the snap-in protrusions to complete lateral self-locking, which not only eliminates the tedious operation of traditional flange alignment, but also enhances the cross-model adaptability, and can achieve rigid connection without introducing additional fasteners, further simplifying the disassembly and assembly process and reducing the risk of assembly errors caused by manual misoperation, thereby ensuring the uniformity of scraping ink pressure distribution and process consistency during printing.

[0022] In the embodiment of the present invention, the linkage module 101 includes a guide shaft 123 installed on the wing plate, the net arm connecting member 107 is rotatably connected to the guide shaft 123, the bridge member 108 is installed on the net arm connecting member 107 and extends to the cam assembly 111, and the length of the bridge member 108 is greater than the displacement corresponding to the maximum swing angle of the cam assembly 111; The technical solution of the present invention significantly improves the reliability and motion quality of the coordinated action of the scraper arm and the net arm by optimizing the mechanical transmission path and stroke redundancy design of the linkage module 101. The guide shaft 123 is fixed to the wing plate and provides a high-rigidity rotation fulcrum for the net arm connecting member 107, ensuring that its swing trajectory is strictly controlled. The bridge member 108 extends to the cam assembly 111 with a length exceeding the stroke requirement. Its redundant design can not only cover the displacement change under the maximum swing angle of the cam, avoiding the mechanism jamming or stress concentration caused by the extreme position, but also amplify the driving torque input by the cam through the lever effect, ensuring the smooth opening / tightening of the scraper arm and the net arm under high load conditions. At the same time, the combined structure of the bridge member 108 and the guide shaft member 123 forms a multi-level motion constraint, which effectively suppresses the deflection of the connecting parts caused by inertia or vibration during operation, maintains the linearity and repeatability of the scraper pressure transmission, and thus achieves precise control of dynamic balance in complex printing tasks and reduces the risk of mechanical wear after long-term use.

[0023] In the embodiment of the present invention, the cam assembly 111 includes a cam shaft member 124 rotatably mounted on the wing member 103 and a cam member 125 fixedly mounted on the cam shaft member 124, and the cam member 125 is in abutment with the bridge member 108; The technical solution of the present invention realizes the dual improvement of driving force transmission efficiency and adjustment flexibility through the modular design of the split cam assembly 111. The cam shaft member 124 is rotatably mounted on the wing plate member 103 to form an independent rotating shaft system. The cam member 125 is fixed to the shaft member through a keyway or a locking bolt. The separable structure of the two facilitates the replacement of cam profiles with different lift curves according to process requirements. The abutment between the cam member 125 and the bridge member 108 converts the rotational motion of the shaft member into the linear displacement of the bridge member 108. In one embodiment, the abutment contact surface between the cam member 125 and the bridge member 108 is designed with a roller bearing or a low-friction coating to reduce sliding resistance, thereby minimizing power loss under high-frequency operation. The standardized connection interface between the cam shaft 124 and the drive assembly 110 supports rapid switching of electric, pneumatic or manual power sources, enables rapid adaptation of dynamic balance in complex printing tasks, and eliminates the multi-stage transmission errors of the traditional swing mechanism 131 through a rigid connection design, significantly improving the quality of action repetition and long-term stability.

[0024] In the embodiment of the present invention, the limit assembly 109 includes an elastic reset unit 126 for resetting the cam assembly 111. The elastic reset unit 126 includes an elastic member 127 connected to the cam shaft member 124. One end of the elastic member 127 is fixed to the wing plate, and the other end of the elastic member 127 is fixed to the cam shaft member 124. The technical solution of the present invention significantly improves the action reset accuracy and system reliability of the cam assembly 111 by introducing an elastic reset unit 126. The two ends of the elastic member 127 are respectively fixed to the wing plate and the cam shaft member 124. After the cam member 125 drives the bridge member 108 to complete the opening action of the scraper arm and the net arm, the elastic member 127 automatically pulls the cam shaft member 124 to rotate to the initial position through the pre-tightening force, ensuring that the mechanism quickly resets to the preset zero position after each action is completed, avoiding reset deviation caused by inertia or friction resistance; This design not only eliminates the need for manual calibration steps and reduces downtime for adjustment, but also suppresses the vibration amplitude of the cam assembly 111 during high-speed operation or sudden load changes through the continuously applied elastic restraining force, thereby maintaining the stability of the scraper pressure transmission chain; At the same time, the buffering effect of the elastic reset unit 126 can effectively absorb the impact energy in the return stroke of the mechanism, reduce the wear rate of the contact surface between the cam and the bridge member 108, and extend the service life of key components, thereby ensuring the consistency of printing actions and the repeatability of process parameters in long-term and high-frequency operations.

[0025] In the embodiment of the present invention, the elastic reset unit 126 includes a special-shaped member 128 fixedly mounted on the cam shaft member 124, a pull rod member 129 abutting against the special-shaped member 128, and an elastic member 127 fixedly connected to the pull rod member 129, one end of the pull rod member 129 is rotatably mounted on the wing plate, and the other end of the pull rod member 129 is connected to the elastic member 127, one end of the elastic member 127 is fixedly connected to the wing plate, and the other end of the elastic member 127 is connected to the pull rod member 129; The technical solution of the present invention significantly optimizes the reset accuracy and energy buffering efficiency of the cam assembly 111 through a multi-stage linkage elastic reset mechanism. The special-shaped member 128 is fixed to the cam shaft member 124 and rotates therewith, and abuts against the pull rod member 129 through its asymmetric profile to form a variable contact point, driving the pull rod member 129 to swing around the fulcrum on the wing plate; The combined design of the pull rod 129 and the elastic member 127 converts the rotational displacement of the cam shaft 124 into the linear expansion and contraction of the elastic member 127, and uses the lever principle to amplify the adjustment range of the elastic preload force, so that the reset process can provide a progressive reset torque through the stretching / compression of the elastic member 127 to ensure that the cam accurately returns to the initial phase, and can also absorb the impact energy under different working conditions through the dynamic cooperation of the special-shaped member 128 and the pull rod 129; This structure simultaneously realizes the dual functions of high-rigidity reset guide and flexible buffering, which not only avoids the stress concentration problem caused by angular deflection of traditional direct-connected elastic units, but also compensates for the trajectory deviation in the movement of the mechanism through the swing freedom of the pull rod, thereby maintaining consistency of movement in high-speed cycle operations, extending the life of the reset unit and reducing the frequency of maintenance.

[0026] In the embodiment of the present invention, a docking area 131 is provided on the wing plate member 103, and the docking area 131 is used to adapt to the swing mechanism; The technical solution of the present invention significantly improves the connection rigidity and adaptability of the wing plate and the swing mechanism by adding a docking area. The docking area arranged at the rear end of the lower part of the wing plate realizes quick disassembly and assembly with the swing mechanism through a finely machined positioning surface and a fastening interface. Its modular design allows the replacement of swing mechanisms of different specifications according to the printing format or load requirements without the need to reconstruct the overall support frame. At the same time, the geometric parameters and load transfer paths of the docking area are optimized to efficiently transmit the dynamic shear force and impact load generated during the scraper operation to the rigid fulcrum of the swing mechanism, avoiding deformation or fatigue failure of the wing plate caused by local stress concentration, thereby maintaining the stability of the scraper pressure distribution during high-speed printing or processing of special-shaped substrates, and expanding the compatibility of the equipment with different process scenarios; In one embodiment, the swing mechanism is a common structure in the prior art and will not be described in detail here.

[0027] In the embodiment of the present invention, a bridge plate 132 is fixedly connected to the wing plate 103, and a force-bearing arm 133 is fixedly provided below the bridge plate 132; In the technical solution of the present invention, the wing plate and the bridge plate are used as one of the connection structures of the swing mechanism, and the coordinated optimization of the structural strength and maintainability of the wing plate assembly is achieved through a multi-process composite connection strategy. The wing plate, the bridge plate and the load-bearing arm are connected by one or more methods of integral casting, screw connection or welding. The integral structure can eliminate the gap of the assembly interface, ensure the continuity of the load transfer path, and significantly improve the rigidity and torsion resistance of the support frame; The split bolt-on design allows independent replacement or local reinforcement of high-wear areas (such as the load-bearing arm), reducing maintenance costs and extending the life of the main structure; The welding process is applied to key stress concentration areas (such as the joint between the bridge plate and the wing plate), and the shear resistance of the interface is enhanced through fusion connection, which effectively inhibits the fatigue crack propagation under long-term alternating loads; At the same time, this flexible connection solution supports the rapid reconstruction of component forms according to the printing format or load requirements, which not only meets the lightweight requirements of small equipment, but also adapts to the installation of distributed force arms in wide-format scenarios, and ultimately achieves a comprehensive improvement in structural stability, process adaptability and full life cycle economy under complex working conditions; In one embodiment, the comprehensive optimization of the equipment structure strength, load adaptability and manufacturing process is achieved through the diversified configuration design of the bridge plate and the load-bearing arm. The bridge plate is fixedly connected to the wing plate in the form of a plate, a casting or other form. The form selection can balance the requirements of lightness and rigidity based on the working conditions. For example, a cast bridge plate is used to improve vibration resistance or a hollow plate structure is used to reduce dead weight. The truss bridge plate is adopted, through the cross ribs or space truss structure, it can achieve lightweight while ensuring the load-bearing rigidity, which is suitable for the strict requirements of inertial constraints of high-speed printing equipment; I-shaped / box-shaped bridge plates are used to improve bending and torsion resistance through closed sections or rib layout, which is suitable for the high torque load transmission requirements of wide-format printing presses. The curved bridge plate is used to match the space limitations of compact equipment with a streamlined profile, while the stress diffusion characteristics of the curved surface are used to reduce local stress peaks; The split composite bridge deck is composed of multiple standardized sub-modules connected by plug-in or bolts, which can support on-demand length expansion or local reinforcement, and is easy to maintain and replace. The honeycomb bridge plate is built with a bionic honeycomb structure or filled with damping materials, which has the advantages of shock absorption, noise reduction and lightweight, and is suitable for precision printing scenarios; Using topologically optimized special-shaped bridge plates, non-uniform material distribution is achieved based on 3D printing or CNC machining, achieving the optimal stiffness-to-weight ratio under specific working conditions with minimal mass; The number and shape of the load-bearing arms (such as cylindrical and L-shaped) can be flexibly configured according to the printing width or load type, and the force transmission paths in different directions can be matched through geometric configuration optimization. For example, the L-shaped structure enhances bending stiffness, and the cylindrical design adapts to multi-directional loads. This modular combination mechanism not only supports standardized mass production to reduce manufacturing costs, but also allows rapid customization of highly compatible structures for special scenarios. At the same time, the rigid connection interface between the bridge plate and the load-bearing arm ensures uniform stress diffusion during dynamic operation and reduces local fatigue damage, ultimately achieving long-term stable operation of the equipment and effective control of maintenance costs under complex printing conditions.
