Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, specifically to a mechanism for receiving screen printing equipment components or devices. Background Technology

[0002] Screen printing equipment is a specialized machine used to achieve the printing process. Its principle is to use a squeegee to transfer ink from the image area on a pre-made screen to the substrate. The equipment that achieves this purpose is called screen printing equipment. Its core components include the squeegee arm assembly and the screen arm assembly. The two need to work together to achieve the screen printing process: the screen arm assembly fixes the screen through a clamping mechanism, while the squeegee arm assembly drives the squeegee to scrape the ink on the screen surface at a specific angle and pressure, so that it penetrates evenly into the substrate. The spatial relative position and dynamic balance between the two directly affect the printing quality / effect.

[0003] However, in existing equipment, the squeegee arm and screen arm are usually designed as a set, and their receiving mechanism has functional limitations. On the one hand, the traditional structure can only adapt to components of specific specifications, requiring the independent development of dedicated receiving bodies for different configurations, increasing R&D costs and maintenance complexity. On the other hand, the existing mechanism lacks dynamic adjustment capabilities, making it impossible to quickly release the screen for cleaning or replacement through opening actions, and also difficult to accurately maintain the rigid coupling relationship between the squeegee arm and screen arm through tightening actions, affecting printing stability. In addition, due to the space constraints of single-end swing arm equipment, traditional swing mechanisms cannot achieve high torque output in a compact layout, and the low standardization of power input interfaces results in insufficient compatibility with diverse frame designs, irregularly shaped substrates, and external drive units, restricting the expansion of equipment application scenarios.

[0004] In summary, existing screen printing equipment suffers from insufficient compatibility issues in the receiving mechanisms of the squeegee arm and the screen arm. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figure 1-3 A mechanism for receiving components or devices of screen printing equipment, including a support frame 100, a linkage module 101 and a limit adjustment module 102;

[0030] The support frame 100 includes a first wing plate 103 and a second wing plate 104 disposed on both sides. The upper front end of the first wing plate 103 and the second wing plate 104 is provided with a preset interface 105, which is used to dock with the scraper arm assembly.

[0031] The linkage module 101 is installed below the preset interface 105 and includes a net arm connector 107 rotatably connected between the first wing plate 103 and the second wing plate 104. A rearwardly extending bridging member 108 is installed on the net arm connector 107.

[0032] The limit adjustment module 102 is integrated in the middle of the wing plate and includes a limit component 109 and a drive component 110. The limit component 109 includes a cam component 111, which is linked with the bridge component 108 to control the lifting and lowering of the bridge component 108. The drive component 110 includes an external power source or a manual operation unit for driving the cam component 111 to rotate.

[0033] A cast connector 114 is fixed at the lower end between the first wing plate 103 and the second wing plate 104. A swing arm mounting hole 115 is opened at the lower end of the cast connector 114, and a swing arm rod 117 is installed in the swing arm mounting hole 115.

[0034] This utility model's technical solution significantly improves the core performance of screen printing equipment through multi-dimensional optimization design;

[0035] Through the composite frame structure of the cast connector 114 and the double-sided wing plate, a rigid connection structure is formed at the lower end of the equipment. Its internal stress distribution optimization design can withstand the high-intensity dynamic load during the screen clamping and squeegee pressure process, avoiding the deformation risk of the traditional single-arm structure. The swing arm 117 converts the input torque into amplified rotational torque. Combined with the high torsional resistance of the cast base, the overall mechanism can still achieve high-intensity torque output capability in a compact layout. This combination of physical leverage effect and rigid base not only meets the high pressure requirements required for large-area printing, but also ensures the dynamic synchronization accuracy of the squeegee arm and screen arm in high-frequency movement.

[0036] The cam assembly 111 of the limit adjustment module 102 adopts an asymmetrical contour design. Driven by an external power source (such as a servo motor) or a manual operation unit, the cam phase switching can be precisely controlled to control the lifting stroke of the bridging component 108. During the printing stage, the high point of the cam locks the bridging component 108 to form a rigid connection with the screen arm, eliminating the gap between the components and ensuring uniform transmission of the squeegee pressure. When the screen needs to be replaced, the cam rotates to the low point to trigger the rapid descent of the bridging component 108, which automatically releases the screen clamping mechanism. Compared with the traditional bolt fastening method, maintenance efficiency is improved.

[0037] The preset interface 105 of the support frame 100 adopts a standardized size chain design, and its interface slot can be adapted to the installation and positioning of different types of scraper arm components; the mesh arm connector 107 of the linkage module 101 adopts a replaceable bushing design, and by adjusting the inner diameter of the bushing to match the mesh screen shaft of different diameters, there is no need to replace the entire receiving mechanism when upgrading the equipment, thus reducing R&D costs.

[0038] This utility model's technical solution effectively enhances the compatibility and dynamic adjustment capabilities of screen printing equipment through an integrated mechanism. The support frame 100 uses double-sided wing plates with pre-set standardized interfaces to achieve rapid docking and multi-specification adaptation of the scraper arm assembly. The composite structure design of the screen arm connector 107 and bridging component 108 in the linkage module 101, based on the rigid support provided by the cast connector 114 and combined with the lever amplification effect of the swing arm rod 117, significantly enhances torque transmission efficiency, breaking through the spatial constraints of traditional single-end rocker arms. The limit adjustment module 102 innovatively adopts a cam linkage mechanism, which precisely controls the lifting stroke of the bridging component 108 through power source drive or manual operation. It can maintain the rigid coupling relationship between the scraper arm and the screen arm during the printing stage to ensure stable pressure, and can also quickly release the screen for operation through cam phase switching. The modular design achieves a balance between high torque output and dynamic adjustment. The standardized interface significantly improves compatibility with irregularly shaped frames and diverse drive units, ultimately forming a new type of receiving mechanism with strong load capacity, precise control characteristics, and wide adaptability, providing core support for the stable operation and process expansion of screen printing equipment under complex working conditions.

[0039] In this embodiment of the utility model, the front end face of the cast connector 114 is provided with an upper preset groove 118 and a lower preset groove 119, and a reinforcing plate 120 is formed between the upper preset groove 118 and the lower preset groove 119. The upper end face of the cast connector 114 and the reinforcing plate 120 are respectively provided with an upper through hole 121 and a lower through hole 122 for alignment and mating.

[0040] This utility model embodiment constructs a multi-level stress dispersion and composite installation system by setting reinforcing plates and configuring alignment through holes between the upper and lower preset slots. The reinforcing plates form a truss-like support structure between the upper and lower slots, significantly improving the bending and torsional deformation resistance of the cast connectors. The layered layout and longitudinal stiffness enhancement design effectively disperse the local stress concentration caused by the dynamic load of the screen. The alignment and matching characteristics of the upper and lower through holes enable precise positioning and coordinated fixing of cross-layer lines or pipelines, facilitating the routing of lines or pipelines, thereby making the overall space more compact. The cast connector 114 significantly shortens the installation and adjustment time while ensuring the overall rigidity of the structure, providing an efficient and stable basic load-bearing frame for equipment maintenance, upgrades, and functional expansion.

[0041] In this embodiment of the utility model, cylindrical protrusions 123 are raised on the inner bottom surfaces of the upward preset groove 118 and the lower preset groove 119 on the side wall of the swing arm mounting hole 115.

[0042] This utility model embodiment constructs a multi-point three-dimensional support system by setting cylindrical protrusions 123 protruding into the upper and lower preset grooves 119 on the side wall of the swing arm mounting hole 115. This significantly enhances the shear resistance and deformation resistance of the area around the mounting hole. The protrusion structure forms a cross-layer mechanical transmission path by embedding into the preset groove, dispersing the swing load transmitted by the swing arm member 117 to the overall frame of the cast connector 114. This effectively avoids stress concentration in the weak area of ​​the mounting hole wall, reduces the self-weight of the casting, and optimizes the economic practicality of the casting.

[0043] In this embodiment of the utility model, the upper end face of the cast connector 114 is provided with a first swing arm fixing hole 124 that communicates with the swing arm mounting hole 115, and the upper end face of the swing arm rod 117 is provided with a second swing arm fixing hole 125 that aligns and cooperates with the swing arm fixing hole.

[0044] This utility model embodiment constructs a through-type positioning and anchoring system by setting first and second swing arm fixing holes 125 that are aligned and connected to each other on the upper end face. This creates a two-way mechanical constraint at the joint interface between the swing arm member 117 and the cast connector 114, significantly reducing the risk of micro-displacement of the connection part under dynamic load. The alignment design of the upper and lower fixing holes ensures that precise coaxial positioning of cross-layer components can be achieved without complicated adjustments during installation. This simplifies the assembly process and enhances the overall structure's resistance to off-center loads through the synergistic locking effect of the through holes. This maintains the linearity of the swing arm's motion trajectory and the repeatability of the positioning accuracy under high-frequency swing conditions. At the same time, it provides an intuitive alignment benchmark for quick disassembly and assembly during subsequent maintenance, effectively balancing the contradiction between the rigidity requirements of the mechanism and maintainability.

[0045] In this embodiment of the utility model, the lower end of the swing arm 117 is sleeved with a swing mechanism docking part 126;

[0046] This utility model embodiment forms a modular quick-change interface by sleeved the swing mechanism docking piece 126 at the lower end of the swing arm member 117. It retains the core function of swing torque transmission and achieves stepless adaptation between the docking piece and the external drive unit through the radial constraint and axial degree of freedom separation design of the sleeve structure. This design allows for quick replacement of worn docking pieces or switching between different power interface types without disassembling the main structure, significantly reducing maintenance time and costs, and improving the compatibility of the mechanism with different drive sources (such as crank connecting rods, hydraulic cylinders, air cylinders or motors). It provides a flexible connection foundation for the multi-functional expansion and working condition adaptability upgrade of the equipment.

[0047] In this embodiment of the utility model, a limiting installation groove 127 is provided at the lower end of the swing arm rod 117, a limiting plate 128 is installed at the lower end of the swing arm rod 117, a first limiting fixing hole 129 is provided on the limiting plate 128, and a second limiting fixing hole 130 is provided at the lower end of the swing arm rod 117 to align and cooperate with the first limiting fixing hole 129.

[0048] This embodiment of the invention integrates a limiting mounting groove 127 and a set of alignment fixing holes at the lower end of the swing arm member 117 to construct a detachable limiting constraint system. The limiting plate 128 and the double fixing holes at the end of the member form a cross-locking mechanism, which not only suppresses radial movement during the swing process through the rigid support surface of the groove sidewall, but also achieves three-dimensional constraint of axial displacement through the through-type fastening of the upper and lower alignment hole sets. The modular design of the limiting plate 128 allows for flexible adjustment of the limiting threshold according to the working conditions. Its geometric adaptation characteristics with the mounting groove automatically compensate for machining tolerances during assembly, ensuring that the limiting reference surface is strictly perpendicular to the swing arm's motion trajectory, thereby accurately controlling the swing amplitude boundary in high-frequency reciprocating motion. This structure significantly reduces the impact of local wear caused by long-term impact on the overall mechanism accuracy through the quick replacement capability of the separate limiting unit, while providing an expandable physical interface for the adaptation of drive units with different stroke specifications, comprehensively enhancing the motion stability and mechanism durability under dynamic loads.

[0049] In this embodiment of the utility model, the swing mechanism docking part 126 includes a U-shaped snap-fit ​​part 131 that is snapped into the limiting mounting groove 127. The left and right side walls of the U-shaped snap-fit ​​part 131 are respectively provided with a first docking hole 132 and a second docking hole 133 for alignment and cooperation.

[0050] This utility model embodiment constructs a multi-directional self-locking docking mechanism through the nested cooperation of the U-shaped snap-fit ​​131 and the limiting mounting groove 127. The double docking hole design on its left and right side walls forms a through-type bidirectional force-locking structure, which not only utilizes the elastic deformation characteristics of the U-shaped opening to achieve rapid snap-fit ​​positioning, but also eliminates the circumferential deflection that is easy to occur in traditional single-point fixing through the double hole alignment and locking. The curved surface fit characteristics of the inner wall of the snap-fit ​​and the limiting groove convert the swing torque into a uniformly distributed contact surface pressure, effectively suppressing fretting wear under high-frequency action. At the same time, the symmetrical support characteristics of the U-shaped structure can automatically compensate for the coaxiality deviation during the docking process, ensuring the linear transmission of driving force. This design realizes the rapid switching of the swing mechanism interface through modular and replaceable snap-fit ​​units, which not only retains the core function of rigid connection, but also provides customized adaptation solutions for different driving modes (such as intermittent impact load or continuous smooth motion), significantly improving the durability and adaptability of the mechanism.

[0051] In this embodiment of the present invention, a steering adjustment assembly 134 is provided on the outer side of the first wing plate 103 and the second wing plate 104. The steering adjustment assembly 134 includes bearing seats 135 respectively provided on the outer side of the first wing plate 103 and the second wing plate 104. A bearing guide shaft 136 is installed in the middle of the first wing plate 103 and the second wing plate 104. The two ends of the bearing guide shaft 136 are rotatably engaged in the bearing seat 135.

[0052] This embodiment of the invention constructs a spatial self-balancing steering architecture by configuring an integrated steering adjustment component 134 on the outer side of the first and second wing plates 104. The coaxial linkage design of the bearing guide shaft 136 and the double-sided bearing seats 135 upgrades the traditional single-point hinge to a full-circumferential rotational support. The precise fit of its two ends in the bearing seats 135 eliminates the lateral clearance when the wing plate deflects and significantly reduces the adjustment resistance through the rolling friction pair. The component automatically corrects the accumulated assembly error through the geometric constraint relationship between the guide shaft and the bearing, so that the double-sided wing plates always maintain a symmetrical motion trajectory under dynamic load. At the same time, the modular bearing seat 135 structure allows for quick adjustment of the guide shaft tilt angle to adapt to the contact angle requirements of different printing surfaces. This ensures the smoothness of high-precision steering adjustment and provides a rigid foundation for the equipment to achieve multi-dimensional posture adaptation in complex spatial layouts. Ultimately, it improves the stability of printing quality and extends the service life of key moving parts.

[0053] In this embodiment of the present invention, the cam assembly 111 includes a cam shaft 137 rotatably mounted on the wing plate, a cam 138 fixedly mounted on the cam shaft 137, and the cam 138 abutting against the upper end face of the bridging member 108.

[0054] This embodiment of the invention constructs a highly responsive dynamic pressure regulation system through the surface contact linkage design of the cam shaft 137 and the bridging component 108. The contour curve of the cam component 138 and the geometric adaptation characteristics of the upper surface of the bridging component 108 transform rotational motion into precise linear lifting control. Its optimized surface contact pressure distribution design significantly improves the load uniformity of the contact area, avoiding local stress concentration caused by traditional point contact. The integrated mounting structure of the cam shaft 137 and the wing plate separates the axial constraint and radial rotational degree of freedom, ensuring the smoothness of cam phase adjustment and achieving self-stabilizing locking by utilizing the mechanical balance relationship between the weight of the bridging component 108 and the cam lift, ensuring the dynamic consistency of the doctor blade pressure during printing. This design supports flexible adaptation of different pressure curves through the quick replacement capability of the modular cam assembly 111, providing a controllable and adjustable rigid interactive connection for high-precision printing processes while maintaining the compactness of the mechanism.

[0055] In this embodiment of the present invention, the limiting component 109 includes an elastic reset unit 139 for resetting the cam assembly 111. The elastic reset unit 139 includes an elastic element 140 connected to the cam shaft 137. One end of the elastic element 140 is fixedly connected to the first wing plate 103 and the second wing plate 104, and the other end of the elastic element 140 is fixedly connected to the cam shaft 137.

[0056] This embodiment of the invention constructs an adaptive dynamic balance mechanism through the linkage design of the elastic reset unit 139 and the cam shaft 137. The bidirectional fixed structure of the elastic element 140 continuously provides controllable return force during the cam's movement, which not only eliminates the rigid impact risk of traditional mechanical limiters, but also absorbs the instantaneous energy fluctuations of the kinematic pair through the elastic deformation characteristics. The adjustable preload of the elastic element 140 supports the matching requirements of different reset response speeds, enabling the mechanism to quickly return to the preset working position after the doctor blade pressure is released or the screen is replaced. This design, through a reset strategy that combines flexibility and rigidity, significantly improves the mechanism's anti-interference capability while maintaining high-precision limit function, providing a reliable dynamic self-correction guarantee for continuous and stable printing under complex working conditions.

[0057] In one embodiment, the support frame is integrally welded or cast. Through welding or casting, the support frame is seamless, eliminating the stress concentration problem caused by bolts / rivets in traditional assembled frames. This significantly improves the structural rigidity and resistance to deformation, ensuring high stability when subjected to squeegee pressure and mechanical vibration during screen printing.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
