Production method and equipment for inflatable bed semi-finished product

Abstract

The invention discloses a production method for an inflatable bed semi-finished product. The production method comprises the steps that (1) an upper piece and a lower piece are conveyed to the butt fusion positions of an upper-piece butt fusion mechanism and a lower-piece butt fusion mechanism correspondingly; (2), a pull belt is produced through a pull belt production device and conveyed to the upper-piece butt fusion mechanism and the lower-piece butt fusion mechanism; (3), the upper-piece butt fusion mechanism and the lower-piece butt fusion mechanism connect the front end and the rear endof the pull belt with the upper piece and the lower piece correspondingly in a butt fusion manner to form a finished piece; (4), the finished piece is conveyed to a finished-piece receiving mechanismthrough a finished-piece output group mechanism; (5), the step 2, step 3 and step 4 are repeated, when the length of the finished piece is equal to that of the inflatable bed semi-finished product, the finished piece is cut off to form the inflatable bed semi-finished product, and the finished-piece receiving mechanism takes out the inflatable bed semi-finished product. By means of the productionmethod, fabrication and butt fusion of the pull belt with the upper piece and the lower piece can be completed at a time, the automated degree is high, manpower can be effectively saved, and the production method contributes to improvement of the production efficiency of an inflatable bed. The invention further discloses several types of production equipment applying the production method.

Description

technical field [0001] The invention relates to a production method and production equipment of an inflatable product, in particular to a production method and production equipment of an inflatable bed semi-finished product. Background technique [0002] Inflatable products are not only used in outdoor products or toys because of their light weight, easy storage and easy portability, they are now used in household products, such as common inflatable beds, inflatable sofas and so on. [0003] However, if the inflatable product (such as an air bed) is to be set into a predetermined shape, it must be realized by its internal structure. If the existing air bed has a drawstring type air bed, if there is no drawstring structure inside, the air bed is likely to become a balloon. The existing pull belts include I-type mesh pull tape, I-type sheet pull tape, and I-type wire pull tape, wherein the I-shaped sheet pull tape includes I-type sheet PVC pull tape, I-type sheet-shaped sandw...

AI Technical Summary

Problems solved by technology

The existing pull belts include I-type mesh pull tape, I-type sheet pull tape, and I-type wire pull tape, wherein the I-shaped sheet pull tape includes I-type sheet PVC pull tape, I-type sheet-shaped sandwich pull tape, The material of the I-type sheet-shaped PVC drawstring is a layer of PVC material layer; the material of the I-type sheet-shaped sandwich drawstring is at least one intermediate layer sandwiched between two layers of PVC material layers, and the intermediate layer can be It is made of mesh or non-woven fabric; these kinds of pull straps are welded to the upper and lower sheets to form the semi-finished product of the inflatable bed. At present, manual welding is still used, and the operator needs to weld the pull straps to the upper and lower sheets one by one, which is very time-consuming. Not conducive to the production of inflatable beds
