[0002] An air-cushioned sole mainly consists of an insole, airbag rubber material, sole rubber material, and air-cushion design, etc. Among them, the air-cushion design is the core. It forms an air storage cavity that can form an air cushion between the upper part of the sole and the lower part of the sole. These air storage cavities and the air inlet channels and air outlet channels provided on the shoe form a ventilation device. The air inlet channels are usually vertically arranged at the rear end of the shoe and communicate with the air storage cavity from top to bottom, while the air outlet channels are horizontally arranged at the upper part of the sole and communicate with the air storage cavity inside the shoe respectively from top and bottom. In this way, when the foot lands, the air cushion can absorb the ground reaction force and play a role in shock absorption.

[0003] There is an existing inflation device for producing air-cushioned soles with the application number CN202321910628.6.

There are several clamping structures, and each clamping structure is connected to one side of the clamping bottom. There are several support frames, and each support frame is connected to one side of the box body. The box body on one side of the housing houses the air pump.

The longitudinal movement threaded hole is threadedly connected to the longitudinal movement screw rod (706).

7. The production equipment of the air cushion sole with a multi-stage shock absorption system according to claim 6, characterized in that: A stable connection frame (801) is arranged at the central position on the upper side of the fixed pressing plate (8). The stable connection frame (801) is slidably clamped with the vertical connecting rod (708). A stable connection hole is formed inside the stable connection frame (801). The stable connection hole penetrates through the vertical connecting rod (708). A fixing bolt (802) is slidably clamped inside the stable connection hole. A combined mounting plate (901) is fixedly welded at the upper end of the positioning and shaping frame (9). Assembly threaded holes are designed at the four corners of the fixed pressing plate (8). The assembly threaded holes penetrate through the combined mounting plate (901). Combined bolts are threadedly installed inside the assembly threaded holes.

8. A process for producing an air-cushioned sole with a multi-stage shock-absorbing system using the production equipment described in claim 7, characterized in that, The steps are as follows: S1. Initially adjust the equipment state. The user installs the fixed pressing plate (8) with an appropriate specification at the lower end of the positioning structure (7) as needed, and installs the positioning and shaping frame (9) with a corresponding specification on the lower surface of the fixed pressing plate (8). Adjust the fixed pressing plate (8) through the positioning structure (7) so that one end of the fixed pressing plate (8) is slidably attached to the positioning adjustment plate (3). Rotate the telescopic adjustment screw rod (403) to push the L-shaped support plate (401) to be attached to the other end of the fixed pressing plate (8). S2. Prepare the sole material. The user applies glue to the upper surfaces of the respective shoe sole layers to be combined and pasted, and places them on the upper surfaces of the respective layer structures in the device respectively. S3. Push the material for positioning. Drive the height-adjusting threaded rod (505) through the height-adjusting motor (506) to adjust the height of the height-positioning frame (501). Turn on the basic positioning structure (2) and the combined transmission structure (5) to push the raw material to the upper surface inside the L-shaped support plate (401). Rotate the fixed-height screw rod (602) to adjust the height of the limit baffle (601), prevent the raw material from deviating, improve the conveying and positioning effect of the raw material, and stack the raw material in the correct position. S4. Perform lamination processing on the material. Turn on the up-and-down motor (704) to drive the fixed pressing plate (8) to descend. Further integrate and limit the position of the material through the positioning and shaping frame (9), align the shock-absorbing layers with each other, and apply a certain pressure to them to achieve stable adhesive connection and realize the rapid combination of the air cushions.
