Description

Technical Field

[0001] The utility model belongs to the technical field of screen printing, and particularly relates to a screen stretching device for a silk screen printing screen. Background Art

[0002] Screen stretching refers to the work of stretching the screen tightly on the screen bar, which is mainly used in the silk screen industry and the printing industry. The quality of screen stretching is directly related to the quality of the screen-printed products, such as overprint accuracy, image clarity, uniformity of the ink layer, and the degree of jagged lines and moire of the image. Therefore, screen stretching is an important link in screen printing. However, during the screen stretching process, personnel are required to manually fix the screen, which may easily cause the screen to become loose. A device that can conveniently fix the screen is now proposed. Utility Model Content

[0019] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific substrate 201 and the splint 203 described in the above embodiments. For example, the anti-slip rubber sheet on the substrate 201 and the splint 203 should be made of a material with a certain softness. The purpose of this setting is to prevent the mesh from being crushed and damaged in this way.

[0020] Specifically, slide cylinders are fixedly connected to both sides of the clamping plate 203 , and one side of the slide cylinder is slidably connected to a slide rod 206 , and the slide rod 206 is fixedly connected to the slide plate 202 .

[0021] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific sliding rod 206 described in the above embodiments. For example, a damping rubber strip is provided on the sliding rod 206. The purpose of this setting is to increase the damping effect of sliding thereon in this way, while preventing abnormal noise during sliding.

[0022] Specifically, the slide cylinder on the other side is threadedly connected to the screw rod 204 , the screw rod 204 is rotatably connected to the slide plate 202 , and the top end of the screw rod 204 is fixedly connected to a lever 205 .

[0023] For the above example, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific screw 204 described in the above embodiment.
