The sofa framework is supported by the wooden frame and is too high, so that the frequent stooping of a processing person when the sofa armrest shaping cotton block, the sofa backrest shaping cotton block and the sofa cushion shaping cotton block are stuck is avoided, and the physical and mental health of the staff is favorably ensured.
Further, the step S9 of spraying the adhesive on the bottom of the sofa frame includes: and adjusting the relative positions of the semi-finished sofa and the wood frame to align the bonding identification line on the bottom surface of the semi-finished sofa with the outline of the wood frame, and spraying the adhesive on the part, which is not shielded by the wood frame, at the bottom of the sofa frame after the position of the sofa frame is adjusted. The bonding position of the sofa outer cover is marked through the wooden frame, the edge of the sofa outer cover is bonded at the bottom of the sofa, the excessive use of the adhesive can be avoided, and the redundant residual glue at the bottom of the finished sofa is avoided.
Further, the step S9 further includes: spraying the adhesive on the bottom of the sofa framework, spraying the adhesive on the edge of the inner surface of the sofa outer cover, heating and softening the edge of the surface of the sofa outer cover by using hot air at 55-65 ℃, flattening the edge of the sofa outer cover, pressing and bonding the edge to the bottom of the semi-finished sofa, and cutting off the redundant sofa outer cover along the edge of the wooden frame after bonding. The surface of the sofa outer cover is heated by hot air to soften the local part of the sofa outer cover, the edge part of the sofa outer cover is pulled to be flat and then is bonded to the bottom of the sofa, and redundant materials are cut off to ensure that the sofa outer cover is fully attached to the semi-finished sofa.
Furthermore, the adhesive and the bonding glue are epoxy high-temperature glue. The epoxy high-temperature adhesive can bear the temperature of 80 ℃ or 120 ℃, and the adhesive is prevented from being denatured and losing the viscosity when the outer cover of the sofa is heated and softened by hot air.
The invention has the beneficial effects that: the edges and corners of the covering material on the surface of the furniture are adhered to the bottom of the sofa in place, the adhesive force is strong, the covering material is not easy to expose in the use process of the furniture, the operation steps of workers are simplified, the subsequent processing is convenient, and the quality of furniture products is improved.
