It is easy to carry and move, and the inflatable cushion is favored by many people.

[0003] In the prior art, inflatable cushions are manufactured by means of high-frequency heat sealing devices. When the heat sealing device is working, a high-frequency welding plate is matched with a lower mold through a pneumatic device so that the two pieces of fabric of the inflatable cushion are heat-sealed together. However, the high-frequency welding plate will vibrate during the moving contact process, which may cause the inflatable cushion to easily shift when heat-sealed, thus affecting the quality of the inflatable cushion. In addition, it takes a certain amount of time to load and unload the inflatable cushion. Currently, the inflatable cushion manufacturing device on the market has only one set of loading mechanism, so the production efficiency of the inflatable cushion is low and the equipment cost investment is large.

[0029] The utility model is an inflatable cushion making device, and its working principle is explained in conjunction with the accompanying drawings:

[0030] Before use, four staff members can be arranged to operate, with two of them standing in a group. Figure 2At four places ABCD, when the utility model is used, the staff at two places AC first load the materials (first put a layer of inflatable cushion fabric on the lower mold, then put sponge on the inflatable cushion fabric, and finally attach another layer of inflatable cushion fabric), align the inflatable cushion fabric with the mark 222, start the motor 31, and the output shaft of the motor 31 rotates to drive the driving rod 32 to rotate, and the driving rod 32 also rotates relative to the sliding sleeve 33. The sliding sleeve 33 will slide on the guide rod 214 at the same time, thereby driving the lower mold assembly 2 to move to the bottom of the heat sealing machine body 4. Finally, the driving rod 32 tends to be parallel to the guide member 11 from the oblique direction. When the mold assembly 2 is located below the heat sealing machine body 4, the cylinder 41 starts to drive the high-frequency welding plate 42 to move toward the lower mold assembly 2. When the high-frequency welding plate 42 contacts the lower mold, the connecting block 221 will move downward in the connecting groove 212 (the lower mold will move downward in the accommodating cavity 211), and the shock-absorbing spring 5 is compressed and deformed under force, which plays a shock-absorbing role. The high-frequency welding plate 42 heat-seals the inflatable cushion fabric. At the same time, the staff at BD carry out material loading. When the lower mold assembly 2 on the left completes heat sealing and retreats to unload materials, the lower mold assembly 2 on the right enters under the heat sealing machine body 4 to perform heat sealing operations.
