DETAILED DESCRIPTION

[0033] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiment is only a part of the embodiment of the utility model, and is not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the scope of the utility model protection.

[0034] Please refer to Figures 1-6 , a simple printing mechanism for receiving a screen printing equipment assembly or device, comprising a support frame 100, a linkage module 101, a limit adjustment module 102 and a swing mechanism docking assembly 125;

[0035] The support frame 100 comprises a first wing plate 103 and a second wing plate 104 arranged on both sides, and 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 for docking and cooperating with the squeegee arm assembly;

[0036] The linkage module 101 is installed below the preset interface 105 and comprises a screen arm connecting piece 107 rotatably connected between the first wing plate 103 and the second wing plate 104, and a bridge piece 108 extending rearward is installed on the screen arm connecting piece 107;

[0037] The limit adjustment module 102 is integrated in the middle of the wing plate and comprises a limit component 109 and a driving component 110, the limit component 109 comprises a cam component 111, the cam component 111 is linked and matched with the bridge piece 108 to control the lifting of the bridge piece 108, and the driving component 110 comprises an external power source or a manual operation unit to drive the rotation of the cam component 111;

[0038] The first wing plate 103 and the second wing plate 104 are provided with a steering adjustment component 114 outside, the steering adjustment component 114 comprises a bearing guide shaft piece 115 fixedly arranged on the first wing plate 103 and the second wing plate 104, the left and right ends of the bearing guide shaft piece 115 are rotatably connected with a left bearing seat 116 and a right bearing seat 117 respectively, and the left bearing seat 116 and the right bearing seat 117 are fixedly arranged on the rack respectively;

[0039] The first wing plate 103 and the second wing plate 104 of the support frame 100 adopt a standardized preset interface 105 design, which can be matched with a modular docking structure through accurate dimensional tolerance, can be adapted to different forms of squeegee arm assemblies, solves the drawback that the traditional matching structure can only be compatible with a single type of component, this design not only supports quick replacement of the squeegee arm and screen arm assembly, but also can flexibly cope with special printing materials or special printing process requirements through interface expansion, significantly reduces the equipment modification cost;

[0040] The web arm connecting piece 107 and the bridging piece 108 of the linkage module 101 constitute a lever transmission mechanism, which can realize high-precision lifting control under the driving of the cam assembly 111 of the limit adjustment module 102. When the screen needs to be replaced or cleaned, the bridging piece 108 is quickly lifted to release the screen clamping force, thereby shortening the downtime. During the printing stage, the cam assembly 111 keeps the bridging piece 108 stable through a self-locking structure, so that a rigid mechanical transmission path is formed between the squeegee arm and the web arm, eliminating the vibration or deviation caused by the gap of the traditional swing mechanism, ensuring uniform distribution of the squeegee pressure, and improving the edge definition and ink penetration consistency of the printed pattern.

[0041] The bearing guide shaft piece 115 of the steering adjustment assembly 114 adopts a low-friction coefficient bearing and a stepped shaft structure to realize efficient transmission of bidirectional torque in a limited space. The left and right bearing seats 117 are independently fixed to the workbench, which can offset the eccentric load stress when the screen moves horizontally and avoid the frame deformation caused by single-sided support. In addition, the driving assembly 110 supports an electric servo motor or a manual wheel disc dual-mode input, which realizes plug-and-play with an external power source through a standardized shaft coupling interface, meeting the compatibility requirements of high-precision automatic production lines and small manual devices.

[0042] The whole mechanism adopts a non-welding assembly structure, and each module is connected through bolts and positioning pins to reduce assembly difficulty. The cam surface of the limit adjustment module 102 is additionally provided with a wear-resistant coating, and the service life is extended through a detachable design. When maintaining, only the worn bushing needs to be replaced instead of the whole assembly, which greatly reduces the cost of spare parts. At the same time, the split design of the web arm connecting piece 107 and the bridging piece 108 allows them to be individually disassembled and repaired, avoiding the problem of overall scrapping caused by local damage in the traditional integrated structure.

[0043] The swing mechanism docking assembly 125 is integrated below the main load-bearing area of the wing plate, adopts a modular quick-release structure design, and is suitable for direct docking and installation of a swing mechanism driven by a pneumatic, electric, or hybrid drive unit, meeting the matching requirements of the squeegee arm assembly. The rigid coupling design of the swing mechanism docking assembly 125 and the frame main structure ensures efficient transmission of swing torque, avoids energy loss during power input of the swing mechanism, and suppresses the interference of high-frequency motion on the stability of the frame.

[0044] The longer the distance between the swing mechanism docking assembly 125 and the bearing seat in space position, the more innovative the driving efficiency is amplified through the physical lever principle. The increase in the distance between the swing mechanism docking assembly 125 (swing machine installation fulcrum) and the bearing seat is equivalent to the lengthening of the force arm of the power input, which can significantly improve the effective torque value output by the swing mechanism under the same driving force, enabling the equipment to drive larger loads with lower energy consumption.

[0045] In an embodiment, the extended force arm structure disperses the driving force evenly to the main bearing area of the frame through spatial layout optimization, while enhancing the smoothness of the swinging action and the anti-vibration interference capability; the design realizes the multiplication effect of torque output only through geometric parameter adjustment without adding complex transmission gear sets or additional power sources, which reduces the modification cost and provides technical feasibility for compatibility with different power driving units, and is especially suitable for long squeegee arm assemblies matched with large-area printing.
