Screen stretching method for platemaking

Abstract

The invention relates to platemaking equipment, in particular to a screen stretching method for platemaking. The screen stretching method comprises the steps that (1), a screen is pre-fixed, wherein the four sides of the screen are clamped and stretched to four directions so that the four sides of the screen are located at the same horizontal height and the tension on each position of the screen is uniformly distributed; (2), tension degree is adjusted to make the tensioning force of the screen be uniformly distributed; (3), screen sticking glue is adopted for fixing the screen, and specifically, the screen sticking glue used for fixing the screen on a screen frame coats the screen frame; (4), the screen and a steel mesh are separated, wherein an upward micro-shape change is generated on the screen located above the steel mesh, so that a certain gap is formed between the screen and the steel mesh, and a blade can conveniently cut the screen; and (5), the screen is cut, wherein the blade is started and made to cut the screen along the inner circumference of the screen sticking glue, so that the screen right above the steel mesh is cut off. According to the scheme, the screen stretching method capable of automatically and rapidly cutting the screen flat is provided.

Description

technical field [0001] The invention relates to a device for making templates, in particular to a stretching method for plate making. Background technique [0002] Precision plate-making refers to materials used for precision plate-making such as steel mesh stretched on the screen frame. In the prior art, during precision plate making, mostly the silk screen is tightened on the screen frame with stencil, and then the screen frame is coated with glue to fix the screen on the screen frame. After the fixation is completed, cut the wire mesh directly above the steel mesh with a blade manually, and then tear off the wire mesh above the steel mesh along the edge of the steel mesh. The prior art has the following problems: 1) precision plate-making requires uniform and stable tension of both the wire mesh and the steel mesh on the screen frame. As a result, the prepared plates cannot meet the precision requirements and are discarded, so the requirements for the professional skill...

Problems solved by technology

The prior art has the following problems: 1) precision plate-making requires uniform and stable tension of both the wire mesh and the steel mesh on the screen frame. As a result, the prepared plates cannot meet the precision requirements and are discarded, so the requirements for the professional skills and work experience of the workers are very high; 2) when the workers cut the wire mesh, it is easy to use too much force, and the blade will cut the steel under the wire mesh. Scratches on the mesh lead to scrapping of the steel mesh; 3) The stretching machine cannot automatically cut the mesh, resulting in a large investment in manpower and material resources, and the production cost of precision plate-making increases
