Description

Technical Field

[0001] The invention relates to the field of mesh-drawing machines, and in particular to an automatic mesh-drawing machine. Background Art

[0002] A screen stretching machine is a device used to stretch and fix the screen to the screen frame. It is widely used in the printing industry, especially in screen printing. Its main purpose is to ensure that the screen maintains appropriate tension during the printing process, thereby ensuring the accuracy and quality of printing. Generally, a tensile force is applied to the screen through a mechanical or pneumatic device. A mechanical screen stretching machine usually uses a transmission structure such as a screw and a gear. The screw is rotated manually or electrically to make the screen frame move relative to stretch the screen. A pneumatic screen stretching machine uses the pressure generated by the cylinder to push the screen frame to stretch the screen. During the stretching process, a tension meter is used to measure the tension of the screen. When the set tension value is reached, the screen is fixed to the screen frame by screen glue or other fixing devices.

[0003] After the wire mesh is stretched to the appropriate position by the mesh-stretching machine, another structure is needed to cut it so that it can be fixed to the mesh frame. This method is inefficient and cannot guarantee accuracy. At the same time, when it is connected to the mesh frame, it cannot achieve a good positioning effect, resulting in the size of the wire mesh and the mesh frame not matching, thus affecting its quality.

[0004] Therefore, it is necessary to propose an automatic mesh-drawing machine to solve the above problems. Summary of the invention
