Embodiment 1

[0023] A cooling process for the production of shielding tapes, comprising the following process steps:

[0024] S1. Feeding: Fix the front end of the shielding tape 2 derived from the outlet of the production device 1 on the winding roller 3, turn on the servo motor connected to the winding roller 3, and the servo motor drives the winding roller 3 to rotate to drive the shielding Forward movement of tape 2;

[0025] S2, spray cooling: the shielding tape 2 enters the spray box 5 through the first guide roller 4 at the exit of the production device 1, opens the water inlet valve and the water pump on the water inlet pipe of the spray box 5, and the Water is evenly sprayed to the surface of the shielding tape 2, wherein the temperature of the sprayed water in the spray box 5 is 20°C, and the preliminary cooling process is completed;

[0026] S3, water immersion cooling: the shielding tape 2 that has completed the preliminary cooling process is moved to the water tank 6 by the t...

Abstract

The invention discloses a cooling process for the production of shielding tapes, which comprises the following process steps: material feeding, spray cooling, water immersion cooling, air drying and winding, and finally completes the cooling treatment process. The cooling process used in the production of the shielding tape of the present invention is first cooled by spraying water at a constant temperature, which can avoid damage to the internal structure of the shielding tape in a high temperature state due to sudden cooling, thereby affecting the quality of the product, and can also play a role in preliminary cooling. The role of the shielding tape in the water tank through multiple guide rollers can lengthen its residence time in the water tank and improve the cooling effect; air-drying the water-cooled shielding tape can facilitate the subsequent processing of the tape.

Description

technical field [0001] The invention relates to the technical field of tape production, in particular to a cooling process for the production of shielding tapes. Background technique [0002] Shielding tape is a kind of metal foil or conductive cloth with high conductive adhesive. Its conductive adhesive and conductive substrate form a complete conductor, which can be bonded to any metal surface to complete electrical lapping and electrical sealing of gaps. . Shielding conductive tape is an affordable, easy-to-use shielding material. After the production and drying process of the masking tape, it enters the cooling stage. Generally, cold air is forced to spray on the rubber surface for cooling, and water cooling can also be used. When the shielding tape in a high temperature state is cooled by cold water, it is easy to destroy its internal structure due to the sudden cooling of the temperature, resulting in a decline in product quality. In view of this, it is necessary to...
