Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The integrated pillow foaming production process of the present invention, concrete process is as follows:

[0035] a. Pillow material epidermis is usually made of PVC / PU / velvet. Burn and paste PU film 2 on the back of the cut PVC / PU / velvet piece 1. Put the cut piece 1 together and press a single needle. The woven tape 3 is pasted to the 4 sewing lines of the cutting piece 1 to prevent material leakage. The non-woven tape 3 is hydrophobic, breathable, and impermeable to the material. It is used for foaming and degassing of the cotton, and the finished product 6 of the pillow skin assembly is turned over and sent to the next project;

[0036] b. The raw materials polyether polyol 7 and isocyanate 8 are sent to the material tank in the pumping room respectively, wherein the raw material polyether polyol-A material and isocyanate...

Abstract

The invention relates to an integral pillow foaming production process and a production device thereof. The integral pillow foaming production process is characterized by comprising the following steps that a, a pillow surface is generally made of three materials, namely, PVC (Polyvinyl Chloride) / PU (Polyurethane) / lint, the back sides of cut PVC / PU / lint is adhered to a PU film in a sintered manner, sowing cut pieces with single needles, non-woven cloth adhesive tapes are adhered to sowing lines of the cut pieces to prevent material leakage, the non-woven cloth adhesive tapes are good in hydrophobicity, ventilation and material prevention, holes need to be formed in sealed parts of finished products by using a sewing machine, sowing lines are not needed, cotton can be combined and foamed to exhaust air, total pillow surface finished products are turned inside out and are fed to next procedures. By adopting the process provided by the invention, the trimming time for wrapping assembled pillows and cotton combination and foaming can be shortened, a demolding agent is not needed, mold heating energy consumption can be reduced, the production cost can be lowered, and the production efficiency can be improved.
