Problems solved by technology

Because it is welded by the pull belt, the pattern of the weld line 105 on the surface of the bed body after welding is blurred and not beautiful enough, and the positioning process is complicated. The positioning problem of the mold, the processing time is long, and it cannot meet the needs of mass production

Abstract

The invention discloses a heat-sealing technique for an airbed hole drawstring, comprising the following steps: (A) a plurality of hole drawstrings are positioned between the upper piece and the lower piece of a bed body in a certain position and in a certain arrangement mode; (B) lower heat transmission moulds are positioned at the bottom surface of the lower piece of the bed body and corresponding to hole drawstrings; upper heat transmission moulds are positioned at the superface of the upper piece of the bed body and corresponding to the hole drawstrings; the upper heat transmission moulds and the lower transmission moulds are clamped so that the upper piece and the lower piece of the bed body are tightly against each other; (C) a power supply is started to heat the upper heat transmission moulds and the lower heat transmission moulds; the upper heat transmission moulds heat-seal the upper piece and the hole drawstrings on the superface and the lower heat transmission moulds heat-seal the lower piece and the hole drawstring from the bottom surface; (D) the upper heat transmission moulds and the lower heat transmission moulds are separated and the bed body is taken out. The invention heat-seals the bed body and the hole drawstrings outside the bed body, thereby having the advantages of clear weld mark decorative patterns on the finished products, steady heat-sealing quality and fixed hole drawstring intervals. Meanwhile, the invention discloses heat-sealing equipment for the airbed hole drawstrings with high production efficiency.

Description

1. Technical field: [0001] The invention relates to a welding process and welding equipment for draw tapes in the body hole of an inflatable bed. 2. Background technology: [0002] At present, the air bed is more and more widely used because of its advantages of being easy to carry and not occupying too much storage space, such as field camping, etc. The structure of the general air bed body is as follows: figure 1 As shown, it includes an upper piece 101, a lower piece 102, a hole pull belt 103 and a shroud 104. The top and lower parts of the hole pull belt 103 are welded to the upper piece 101 and the lower piece 102 respectively. When the air bed is inflated, The hole drawstring 103 tightens the upper sheet 101 and the lower sheet 102 so that the bed surface remains flat and does not bulge up. Simultaneously, when a person is lying on the bed, the hole drawstring 103 can evenly bear the load. Such as figure 2 , image 3 As shown, the hole pull tape is actually a strai...
