The sofa is easy to be used for producing products with complex shapes, and is high in production efficiency, low in cost, short in working hour and long in service life.
Description
Technical field
This practicality relates to a kind of sofa, is specifically related to a kind of polyurethane one step foaming shaped sofa.
Background technology
Traditional sofa production method great majority adopt batten or tubing to make sofa frame; Layer adds that with spring materials such as the rope made of hemp, burlap, elastic band stick the elastic inner layer that mode such as sponge is made sofa more within it then; Specifically shown in accompanying drawing 1; It mainly is made up of framework 11, spring 12, elastic cord 13, primer 14, rubber cushion 15, face glue 16, silk flosssilk wadding 17, top layer leather sheath or 18 in cloth cover; The production technology of tradition sofa at first is to make the framework of sofa according to profile, and framework has been formed sofa agent structure and basic styling.Frame material mainly is timber, steel, wood-based plate, and medium density fibre board (MDF) etc. are main with medium density fibre board (MDF) at present, and framework need satisfy modeling requirement and requirement of strength.Make its elastic inner layer and mould the careful profile of sofa profile with sticking card of materials such as spring, elastic cord, sponge and silk flosssilk wadding and fill frame then.To glue the good framework of card, top layer leather sheath or cloth cover and various gadget at last and carry out general assembly, sofa manufacturing process has just been accomplished.This type sofa manufacturing process is extremely complicated, and production process is entirely by manual production, and production is long man-hour, is unfavorable for suitability for industrialized production.Manual production is difficult to guarantee the standard of face shaping in addition, be difficult to especially produce for the complicated sofa of profile geometry, and the elastic layer of this Sofa mattress is sagging easily, and product is not durable.
The utility model content
The purpose of the utility model is to provide a kind of polyurethane one step foaming shaped sofa, and this sofa is easy to produce complex-shaped product, and production efficiency is high, and cost is low, and man-hour is short, long service life.
The above-mentioned purpose of the utility model realizes through following technical scheme: a kind of polyurethane one step foaming shaped sofa; Comprise sofa body and the foot rest that is arranged at sofa body bottom, described sofa body comprises skeleton, covers the polyurethane sponge that passes through the moulding of polyurethane one step foaming on the skeleton and is wrapped in outer field leather sheath of polyurethane sponge or cloth cover.
A kind of improvement as the utility model: between polyurethane sponge and leather sheath or cloth cover, also be provided with the silk floss layer.
The described skeleton of the utility model comprises that a rectangle underframe encloses the frame backrest with being located on the rectangle underframe.
In order to improve the elasticity of the utility model Sofa cushion, the described rectangle underframe of the utility model inside is provided with a plurality of spring bodies that parallel.
In order to strengthen the intensity of this practicality Frame of sofa, be provided with the strengthening part that parallels with spring body at the middle part of said rectangle underframe.
The described strengthening part of the utility model is bar shape or tubular bodies.
The described frame backrest that encloses of the utility model comprises that a symmetry is distributed in the positive backrest of side backrest and between the backrest of both sides on rectangle underframe two opposite side; Described side backrest is made up of with the bend pipe of being located at vertical bar shape top a plurality of bar shapes that vertically are fixed on the rectangle underframe, and described positive backrest is formed by being located at the back bar shape that the back of the body of one between the backrest of both sides time bar shape and extends to form along the bend pipe direction.
For the intensity of the backrest that improves the utility model sofa, be provided with the vertical bar shape of a pair of symmetrical distribution down between bar shape and the back bar shape at the back of the body, vertically be provided with Cross slat body or tubular bodies between bar shape and the side backrest.
For comfort level that improves the utility model sofa and the needs that make it to meet more the body mechanics, at the bend pipe or the curved bar that are used to strengthen positive backrest intensity that also are provided with two symmetrical distributions under the back of the body between bar shape and the rectangle underframe.
The described foot rest of the utility model is located at rectangle underframe bottom, and is fixedly connected with described rectangle underframe.
The utility model has the advantages that:
(1) the utility model sofa manufacturing approach adopts the mould foaming, is easy to produce complex-shaped product, and production efficiency is high, and man-hour is short;
(2) the reaction injection molding foaming formulation that adopts PPG and isocyanates to form; The ability fast foaming is made the polyurethane sofa of high resilience; Long service life; And can control the soft durometer of sofa through the mixed proportion of regulating prescription, be applicable to the production field of sofa, leisure chaise longue, dining chair and chair or the like;
(3) the polyurethane one step foaming shaped sofa in the utility model, through the mould foaming, production efficiency is high; And the reaction injection molding foaming formulation of forming by PPG and isocyanates, after chemical reaction generates the cell diameter size mixed distribution of polyether polyols with reduced unsaturation, and the skeleton thickness is different; Very big percent opening is arranged; When pressurized, can under the different deformation state, produce the bounce of different support forces, make sofa have high resilience, and long service life.
(4) because through the mould plastotype, skeleton only plays increase and receives the force intensity effect, need not satisfy the requirement of moulding, make skeleton be easy to produce, compare with traditional sofa, simplify the structure of sofa greatly, make the production technology of sofa simpler, cost is low, and production efficiency is higher.
