Embodiment Construction

[0023] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] see Figure 1-2 As shown, the above-mentioned cushioning and dustproof foam is used for shock absorption, sealing, waterproof, and dustproof between the camera and the shell cover. The foam includes a semicircular first foam layer 1, pasted on the The second adhesive layer 4 on one side surface of the first foam layer 1, the circular second foam layer 3 pasted on the first foam layer 1 through the second adhesive layer 4, the second adhesive layer 3 through the first adhesive layer 2 the release layer 5 pasted on the surface of the other side of the first foam layer 1, of course, the release layer 5 can also be pasted on the other side of the second foam layer 3, the first foam layer 1 and The inner rings of the second foam layer 3 have the same diameter and are arranged concentrically. In this embodiment, the outer diameters of t...

Abstract

The invention discloses A cushioning and dust-proof foam used for sealing and shock absorption. The foam includes a semicircular first foam layer, an adhesive layer pasted on one side surface of the first foam layer, and pasted on the first foam layer through the adhesive layer. on the foam layer The ring-shaped second foam layer, the release layer pasted on the other side surface of the first foam layer or the other side surface of the second foam layer through another adhesive layer, the first foam layer and the second foam layer The inner rings of the two foam layers have the same diameter and the same center, In the present invention, the annular foam and the semi-circular foam are integrally pasted into stepped foam, which can be inserted between the camera head and the shell cover more obediently, and the sealing and shock absorption effect is good. The invention also discloses a The production process for producing the above-mentioned cushioning and dust-proof foam, The process of the invention realizes automatic waste discharge, reduces fuzz and improves overall production capacity.

Description

technical field [0001] The invention relates to a cushioning and dustproof foam and a production process thereof. Background technique [0002] At present, the sealing and shock-absorbing foam used on mobile phone cameras, NB cameras, digital camera cameras, Internet bar video cameras, various surveillance cameras, mine explosion-proof cameras, etc. are mostly ring-shaped foams on the market. The ring-shaped foam cannot be snugly embedded between the camera and the shell cover, and the sealing and shock-absorbing effect is poor. Contents of the invention [0003] The purpose of the present invention is to provide a step-shaped foam in which the ring-shaped foam and the semi-circular foam are integrated, which can be inserted between the camera and the cover more obediently, and the sealing and shock-absorbing effect is good. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A cushioning and dust-pro...
