High-speed molding device and preparation method for conductive foam cotton

Abstract

The invention provides a high-speed molding device and preparation method for conductive foam cotton, and aims at solving the technical problems that the production efficiency is low, and the quality can not be guaranteed when conductive foam cotton is produced through human assistance. According to the technical scheme, the needed conductive foam cotton is obtained by conducting a series of treatment on a conductive cloth and a sponge strip through a cladding molding device, a heating device, a cooling device, a backing adhesive pasting drawing device and a cutting device; in the cladding molding device, by using a side wall curling structure for a guiding frame and a cladding part, the purpose of cladding the conductive cloth and the sponge strip after aligning the conductive cloth with the sponge strip is achieved, not only can subsequent backing adhesive pasting be convenient, but also a backing adhesive can be aligned at the preconceived conductive cloth attaching portion for sealing, and then the quality of the conductive foam cotton is improved; in addition, cladding of the sponge strip by the conductive cloth can be achieved through the guiding frame and the cladding part without artificial participation, therefore, labor is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic shielding, in particular to a high-speed molding equipment for conductive foam and a manufacturing method thereof. Background technique [0002] With the rapid development of science and technology informatization, industrial products have higher and higher requirements for Electro Magnetic Compatibility (EMC). The ability to withstand electromagnetic interference, so all kinds of electronic equipment at present need to be treated with electromagnetic shielding. At present, the most widely used and most effective shielding material is conductive foam. [0003] Conductive foam is wrapped with conductive cloth on flame-retardant sponge. After a series of treatments, it has good surface conductivity, and can be easily adhered with adhesive to fix it on the required shielding device; The use of foam is increasing, and the requirements for the production equipment of conductive foam are gettin...

AI Technical Summary

Problems solved by technology

[0003] Conductive foam is wrapped with conductive cloth on flame-retardant sponge. After a series of treatments, it has good surface conductivity, and can be easily adhered with adhesive to fix it on the required shielding device; The use of foam is increasing, and the requirements for the production equipment of conductive foam are getting higher and higher. At present, the production equipment of conductive foam generally has the following technical problems: due to the lack of relevant fixtures, before heating, it is necessary to Manually align the conductive cloth and the sponge strip (that is, generally place the sponge strip in the middle of one side of the conductive cloth) to realize the covering of the conductive cloth to the sponge strip. Due to the manual control of the accuracy of the above-mentioned alignment and coating treatment Insufficient, the conductive cloth and the sponge strip cannot be precisely aligned and shifted, causing the conductive cloth to be wrapped on one side of the sponge strip to form a conductive cloth joint that will deviate from the expected position, so that when the subsequent adhesive is applied for sealing, it cannot Sealing the joints of the conductive cloth in some positions will not guarantee the quality; in addition, labor is wasted and the production efficiency is low
