Production method and production dedicated tool for non-woven fabric skylight ceiling
The invention discloses a production method and production dedicated tool for a non-woven fabric skylight ceiling, and belongs to the field of compression molding of automotive trim ceilings. The production dedicated tool comprises a hand-held frame and a tray, wherein the hand-held frame adopts a rectangular frame; the shape of the tray is identical to that of the skylight area of the skylight ceiling; the tray is fixed on the hand-held frame, and is positioned in the middle of the hand-held frame; positioning pillars are arranged on the two sides of the hand-held frame. According to the production method, a layer of industrial PE or PP adhesive film is adhered to the tray of the dedicated tool and is enabled to be compressed between fabric and a base material of the skylight area of the skylight ceiling to reduce release force of the skylight area, and the skylight area is easily separated from the skylight ceiling, so that the problem of difficulty of edge covering of the non-woven fabric skylight ceiling is solved. 1. Non-woven fabric the special tool for the production of ceiling, characterized in that comprises a handheld frame (1), the tray (2), the (1) is a rectangular frame; the tray (2) in the shape of the ceiling with the skylight the same shape as the sunroof area; the tray (2) is fixed to the impulse wire feeder (1) is, and is located in the middle part thereof; the handheld frame (1) two side also provided with a positioning column (3). 2. Non-woven fabric the special tool for the production of ceiling according to Claim 1, characterized in that the tray (2), the positioning column (3) are welded on the impulse wire feeder (1) is. 3. Method for producing non-woven fabric the sunroof the ceiling, characterized in that its steps are: A, the claim 1 of the ceiling skylight the nonwoven fabric in the production of specialized tooling of the tray (2) is a layer of water for industrial use or PE PP film, and the film upward are four corners of a surface of the adhesive double-sided adhesive tape; B, the upper mold can be hung in the fabric, the heating in the heating furnace at 30-120s, the heating temperature is the 200-400 [...] C, in the step A PP with industrial PE or tooling into the mold cavity of the membrane, and the two sides of the positioning column (3) into two of the upper mold in the positioning sleeve, is lifted upwards tooling, enables the industrial film with double-sided adhesive junction of the back of the fabric, and then taken out of the fixture, this step in the 30? ? -100s complete; D, the fixture is taken out, the heating of the substrate by the caterpillar transmission clamp is transmitted to the cavity, with the fabric and in the middle of the industrial PE or PP film common pressing, making complete the sunroof a ceiling. 4. Method for producing non-woven fabric the sunroof a ceiling according to Claim 3, characterized in that the stated industrial PE or to the thickness of the adhesive film PP the 30-100 m.
