A kind of production process of making sofa

Abstract

The invention provides a sofa manufacturing technique. The sofa manufacturing technique includes 1), material preparing, 2), finishing, 3), frame assembling, 4), sponge preparing, 5), inner sofa cushion mounting, 6), frame gluing, 7), jacket cutting and 8), assembling (leather pressing). According to finishing, boards, bent parts and squares are put on a grinding device for surface grinding to remove surface burrs and acute corners of the boards. According to inner sofa cushion mounting, inner sofa cushion shells are filled with quantitative sponge by a sponge filler and a quantitation mechanism. The sofa manufacturing technique has the advantages that in a frame section, surface burrs, acute corners and the like of the selected frame boards are removed by the grinding device; in a lining section, uniformity in quantity of the sofa cushion sponge can be guaranteed each time by the quantitation mechanism, and processes for experimental correction and sofa plumpness improvement of each sofa cushion are omitted; in an assembling (leather pressing) section, operators can turn over sofas by 360 degrees rapidly through a leather pressing device, and station angles can be changed.

Description

technical field [0001] The invention belongs to the technical field of sofa production technology, and in particular relates to a production technology for sofa production. Background technique [0002] According to the shape of the sofa, the current sofa is mainly divided into two types: classical and modern. Classical sofas generally use some traditional modeling elements and traditional craft structures, so the structure is more complicated. The exposed parts of this type of sofa are often decorated with carving, inlaying, drawing, painting and other processes. The production process is long and the technical requirements are high. The production process of modern modeling sofa is relatively simple, and modern new process materials are widely used, and its production process route is short, which is convenient for large-scale production. [0003] The sofa is mainly composed of three parts: frame, filling material and fabric. [0004] (1) The frame constitutes the main ...

AI Technical Summary

Problems solved by technology

[0011] However, there are the following deficiencies in the existing process: firstly, in the frame section, the surface of the selected frame has not undergone any treatment, and burrs and sharp angles are prone to occur, leaving quality problems for subsequent processes; at the same time, in the lining section, the sofa The amount of sponge filled in the cushion is generally filled by the operator based on experience. Sometimes the product is inconsistent due to the gesture of the operator. The amount of sponge in each sofa cushion cannot reach the required amount at one time. Repeated experiments are required, which directly affects production. Efficiency; in the final assembly (palm skin) section, the operator needs to constantly turn the heavy sofa and change different positions, which increases the labor intensity and reduces the work efficiency
