Description

Technical Field

[0001] The utility model relates to the technical field of electric heating components, in particular to a bidirectional electric heating component of a screen plate laminating machine. Background Art

[0002] Stencil, also known as silk screen, is a rigid screen used for printing. When processing the stencil, it is necessary to use screen glue to seal the excess area and leave the required printing area. Generally, the stencil is placed in a laminator, the screen glue is heated and melted, and then pressed on the stencil. After cooling, the screen glue forms a film, thereby covering the excess area of ​​the stencil.

[0003] At present, some stencil laminators on the market are equipped with unidirectional electric heating components, which can only transfer heat to the outside through the electric heating components. After hot pressing the stencil adhesive, the stencil adhesive needs to naturally dissipate heat and eventually condense into an adhesive film, which wastes time, especially in batch production, resulting in low production efficiency of the stencil laminator. Therefore, a bidirectional electric heating component for a stencil laminator is proposed. Utility Model Content
