Description

Technical Field

[0001] This utility model relates to the field of screen printing stretching technology, specifically to a novel screen printing stretching module. Background Technology

[0002] In screen printing, the screen stretching process is a crucial step in fixing the screen to the frame. This process primarily uses mechanical tension to secure the screen to the frame, and the core equipment, the screen stretching machine, comes in two types: manual and pneumatic. Manual stretching machines have become the mainstream choice in the industry due to their cost advantage. During screen printing plate production, the screen needs to be laid on the frame, then stretched using the stretching machine, and finally fixed to the frame with adhesive. After the adhesive dries and hardens, subsequent printing operations can begin.

[0003] However, existing manual screen stretching machines have some problems in use. Because the screen tension is stretched manually, it mostly relies on the operator's experience to judge the screen tension, which often results in uneven tension, easily affecting the stretching effect and printing quality. To address these problems, this utility model proposes a novel screen printing stretching module, aiming to provide a screen stretching module that is easy to operate, provides uniform screen tension, and improves printing quality. Summary of the Invention

[0004] This invention provides a novel screen printing stretching module to solve the problems mentioned in the background art.

[0005] The objective of this utility model is achieved through the following means:

[0006] A novel screen printing stretching module includes a fixed frame and an X-axis stretching module and a Y-axis stretching module crosswise arranged on the fixed frame. A working cavity is provided in the middle of the fixed frame, and a support platform is provided within the working cavity. Each X-axis and Y-axis stretching module includes two oppositely arranged stretching assemblies, which are respectively mounted on the fixed frame via corresponding first guide rails. A drive mechanism for moving one of the stretching assemblies is provided on the fixed frame. A tension / compression sensor for connecting to the other stretching assembly is provided on the fixed frame. A display controller for electrically connecting to the tension / compression sensor is provided on the fixed frame.

[0007] Furthermore, the drive mechanism includes a handle and a screw rotatably mounted on the fixed frame, the screw being connected to the mesh tensioning assembly, and the handle being mounted on one end of the screw.

[0008] Furthermore, the lower end of the support platform is vertically mounted in the working cavity via guide columns, and a cylinder for driving the support platform to move up and down is provided on the inner wall of the fixed frame.

[0009] Furthermore, the netting assembly includes a support bracket and several clamps. The support bracket is mounted on the first guide rail, and a second guide rail is provided on the support bracket. The several clamps are slidably mounted on the second guide rail.

[0010] Furthermore, the fixture is provided with two sets of limiting rollers that cooperate with the second guide rail.

[0011] Furthermore, the clamp includes a quick clamp, a clamping plate mounted on the quick clamp, and a force plate. The force plate is disposed opposite to the clamping plate, and when the quick clamp is driven, the clamping plate and the force plate are in close contact.

[0012] Furthermore, the middle part of the force-bearing plate is provided with a groove for fitting and engaging with the clamping plate.

[0013] Furthermore, anti-slip ripples are provided between the force-bearing plate and the clamping plate.

[0014] This invention, through the cross-configuration of X-axis and Y-axis tensioning modules, ensures uniform force on the wire mesh during tensioning, avoiding uneven tension. Simultaneously, the cooperation of the drive mechanism and tension / compression sensors allows for real-time monitoring and adjustment of the tension, making the tensioning process more precise and controllable.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In this embodiment, refer to Figure 1 - Figure 5 The present invention relates to a novel screen printing stretching module, comprising a fixed frame 1 and an X-axis stretching module and a Y-axis stretching module crosswise arranged on the fixed frame 1. A working cavity is provided in the middle of the fixed frame 1, and a support platform 2 is provided in the working cavity. The X-axis stretching module and the Y-axis stretching module each include two stretching components 3 arranged opposite to each other. The two stretching components 3 are respectively mounted on the fixed frame 1 through corresponding first guide rails 8.

[0023] The fixed frame 1 is provided with a drive mechanism 4 for moving one of the tensioning net components 3, a tension / compression sensor 5 for connecting to the other tensioning net component 3, and a display controller 6 for electrically connecting to the tension / compression sensor 5.

[0024] like Figure 2 As shown, each of the netting components 3 is symmetrically equipped with two tension and compression sensors 5, which can more accurately monitor the changes in tension during the netting process and avoid the tension deviating from the center of gravity, thus affecting the detection accuracy.

[0025] The driving mechanism 4 includes a handle 401 and a screw 402 rotatably mounted on the fixed frame 1. The screw 402 is connected to the tensioning assembly 3. The handle 401 is installed at one end of the screw 402. Rotating the handle 401 drives the screw 402 to rotate, thereby driving the tensioning assembly 3 to move on the first guide rail 8, thus achieving the tensioning or loosening operation of the wire mesh. The tension / compression sensor 5 can detect the tension or pressure on the tensioning assembly 3 in real time and transmit the detection signal to the display controller 6. The display controller 6 displays the received detection signal, allowing the operator to understand the current tensioning status and ensuring the accuracy and safety of the tensioning operation.

[0026] Furthermore, the drive mechanism 4 can also be replaced with a pneumatic push rod or a lead screw motor to adapt to different automation needs.

[0027] The support platform 2 is vertically mounted in the working cavity via four guide columns 201 at its four lower corners. A cylinder 7 is installed on the inner wall of the fixed frame 1 to drive the support platform 2 to rise and fall. By controlling the extension and retraction of the cylinder 7, the support platform 2 can be raised and lowered, thereby adjusting its height and moving the screen upwards to ensure a tight fit between the screen and the wire mesh. The display controller 6 is equipped with a control switch to control the operation of the cylinder 7. Operators can control the extension and retraction of the cylinder 7 by operating the control switch, thus adjusting the height of the support platform 2. Furthermore, the vertically oriented design of the support platform 2 facilitates adaptation to screens of different sizes, improving the versatility and flexibility of the equipment. The guide columns 201 ensure the stability and straightness of the support platform 2 during raising and lowering, preventing deviation or tilting during movement, further guaranteeing the accuracy and safety of the wire mesh stretching operation. The guide column 201 is welded to the lower end of the support platform 2, and the guide column 201 slides with the bushing on the inner wall of the working cavity. This design allows the support platform 2 to move smoothly when it is raised and lowered, and will not affect the netting effect due to shaking.

[0028] The screen stretching assembly 3 includes a support bracket 301 and several clamps 302. The support bracket 301 is mounted on the first guide rail 8, and a second guide rail 9 is provided on the support bracket 301. The clamps 302 are slidably mounted on the second guide rail 9. By adjusting the position of the clamps 302 on the second guide rail 9, it can adapt to screens of different sizes, improving the adaptability and flexibility of the screen stretching module. The X-axis screen stretching module and the Y-axis screen stretching module are cross-set, enabling screen stretching operations in two directions, improving the efficiency and accuracy of screen stretching. This novel screen printing screen stretching module has a simple structure, is easy to operate, and can adapt to screens and screens of different sizes, improving the versatility and flexibility of the equipment. At the same time, through the setting of tension and compression sensors 5 and display controller 6, the screen stretching status can be detected in real time, ensuring the accuracy and safety of screen stretching operations.

[0029] The clamp 302 is provided with two sets of limiting rollers 303 for cooperating with the second guide rail 9. These limiting rollers 303 ensure smooth sliding of the clamp 302 on the second guide rail 9, preventing wobbling or jamming during movement, thus improving the stability and reliability of the net stretching operation. Furthermore, the clamp 302 is provided with locking screws to secure its position. These screws fix the clamp 302 on the second guide rail 9, preventing accidental movement during net stretching and ensuring the accuracy and safety of the operation.

[0030] The clamp 302 includes a quick-release clamp 3021, a clamping plate 3022 mounted on the quick-release clamp 3021, and a force-bearing plate 3023. The force-bearing plate 3023 is disposed opposite to the clamping plate 3022. When the quick-release clamp 3021 is driven, the clamping plate 3022 and the force-bearing plate 3023 fit tightly together, thereby clamping the wire mesh. The quick-release clamp 3021 is simple and quick to operate, which can greatly improve the efficiency of wire mesh stretching operations.

[0031] Furthermore, the force-bearing plate 3023 has a groove in its center for engaging with the clamping plate 3022, thereby increasing the contact area with the stretched mesh, enhancing the clamping force, and ensuring that the mesh is not easily detached or displaced during the stretching process, further improving the stability and reliability of the stretching operation. In addition, the groove design can accommodate meshes of different thicknesses, improving the adaptability and flexibility of the equipment. Anti-slip corrugations are provided between the force-bearing plate 3023 and the clamping plate 3022. These corrugations increase the friction between the force-bearing plate 3023 and the clamping plate 3022 and the mesh, preventing the mesh from sliding or detaching during the stretching process, thus further improving the stability and reliability of the stretching operation. Furthermore, the anti-slip corrugations also reduce wear between the mesh and the clamp 302, extending the service life of the equipment.

[0032] This invention, through the cross-configuration of the X-axis and Y-axis tensioning modules, ensures that the wire mesh is evenly stressed during the tensioning process, avoiding uneven tension issues. Simultaneously, the cooperation of the drive mechanism 4 and the tension sensor 5 allows for real-time monitoring and adjustment of the tension, making the tensioning process more precise and controllable.
