Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

As shown in fig. 1, an embodiment of the present invention provides a composite screen printing plate, including a screen frame 110, a screen cloth 120 and a coating layer, the coating layer covers the screen cloth 120, the coating layer includes a plurality of opening patterns 130, and the screen cloth 120 includes a plurality of metal warp threads 121 and metal weft threads 122.

The opening pattern 130 does not have the metal warp threads 121 or does not have the metal weft threads 122, when the opening pattern 130 does not have the metal warp threads 121, a first included angle is formed between the opening pattern 130 and the metal weft threads 122, and when the opening pattern 130 does not have the metal weft threads 122, a second included angle is formed between the opening pattern 130 and the metal warp threads 121.

Moreover, transition regions 140 are respectively disposed on two sides of the opening pattern 130, when the opening pattern 130 does not have the metal warp threads 121, the transition regions 140 also do not have the metal warp threads 121, and when the opening pattern 130 does not have the metal weft threads 122, the transition regions 140 also do not have the metal weft threads 122.

For example, in fig. 1, the opening pattern 130 region and the transition region do not have the metal warp threads 121.

Specifically, a section of the steel wire can be removed from the corresponding warp 121 or weft 122 by laser or etching. This makes it possible to form a state in which only the warp threads 121 or only the weft threads 122 are present on the opening pattern 130 and the transition area 140.

Specifically, the transition region 140 extends along the length direction of the opening pattern 130. For example, if the opening pattern 130 is rectangular, transition regions 140 are respectively disposed on both sides of the width direction of the rectangle, and the transition regions 140 extend along the length direction of the rectangle.

In particular, the transition zone 140 extends in the direction of movement of the doctor blade. For example, if the opening pattern 130 is rectangular, transition regions 140 are respectively disposed on both sides of the width direction of the rectangle, and the transition regions 140 extend along the length direction of the rectangle. The blades typically run from one end to the other in the length direction of the rectangle. The scraper is arranged in such a way that the resistance received by the scraper is smaller in the operation process, and the scraper can run more smoothly.

In this embodiment, the coating layer is a polymer material layer or an emulsion layer. When the coating layer is a polymer material layer, the polymer material layer covers the mesh cloth 120. However, when the coating layer is an emulsion layer, the emulsion layer covers the mesh cloth 120.

In this embodiment, the first included angle a1 is 0 to 80 degrees. The first included angle a1 is an included angle between the opening pattern 130 and the metal weft 122 when the metal warp 121 is not present in the opening pattern 130. The included angle may be 1 degree, 10 degrees, 50 degrees, 80 degrees, etc.

In this embodiment, the second included angle is 0 to 80 degrees. The second included angle is an included angle between the opening pattern 130 and the metal warp 121 when the metal weft 122 is not present in the opening pattern 130. The included angle may be 1 degree, 10 degrees, 50 degrees, 80 degrees, etc.

In this embodiment, the width d1 of the metal warp 121 or the metal weft 122 that is laser-etched or etched in one direction is 50um to 300 um.

Specifically, the single direction is laser-removed, that is, a section of the metal warp 121 or the metal weft 122 is removed by laser. The etching direction is to remove a section of the metal warp 121 or the metal weft 122 by means of an etching solution.

Specifically, the width d1 may be 50um, 100um, 200um, 300um, etc. This width limitation is favorable to balancing the overall strength of the web and the smoothness of the scraper operation.
