Description

Technical Field

[0001] The present invention relates to an airbag mechanism, in particular to an airbag mechanism arranged inside a pressing groove of a wall-type sole pressing machine, which is composed of a plurality of inflatable airbag units and can press the front and rear ends and sides of shoes. Background Art

[0002] General shoes, such as Figure 1 As shown, the shoe mainly includes an upper 101 and a sole 102. The upper 101 is mainly used to cover the sole of a person's foot, and can be made of cloth, leather or synthetic plastic material. The sole 102 is mainly made of rubber material or other wear-resistant composite materials to improve the safety, functionality and durability of the shoe.

[0003] The upper and sole of the shoe are mainly made of Figure 2A , Figure 2B and Figure 2C The wall-type sole pressing machine 200 is provided with two sets of sole pressing mechanisms 300 on the machine platform 201, and a pressing rod 210, 220 is provided above each of the two sets of sole pressing mechanisms 300. The two pressing rods 210, 220 can be used to press the front end and the rear end of the shoe upper respectively, and the pressing rods 210, 220 can swing left and right to facilitate the replacement of shoe materials.

[0004] Please refer to Figure 3 The bottom pressing mechanism 300 includes a side pressing mechanism 301 that can press against the side of the shoe, and a compression block 302 that can press against the toe and heel of the shoe. The side pressing mechanism 301 is provided with a plurality of side pressing blocks 303, and the side pressing mechanism 301 drives the plurality of side pressing blocks 303 to press against the side of the shoe through a plurality of hydraulic cylinders 304. The compression block 302 is driven by an axial driving mechanism 305 to compress the toe and heel of the shoe.

[0005] Please refer to Figure 4 , which is an existing compression block 302 for compressing the toe and heel of a shoe, and is a solid rubber block as a whole; the existing side pressure block 303 for pressing the side of the shoe, its pressing end is also a solid rubber body 303a, and a fixed iron block 303b is set at the rear end of the solid rubber body 303a.

[0006] However, as the appearance of shoes becomes more and more diverse, the lines are more varied, and the types of curved surfaces around the soles are also increasing. When the curved surfaces on the sides of the soles are becoming more and more diverse, the traditional compression blocks or side compression blocks made of solid rubber are often pre-processed and fixed in shape, and the shape or strength cannot be changed temporarily. Therefore, it is easy for the adhesive surface to not be fully adhered, and it is also easy for the adhesive part to be uneven or wrinkled because it cannot completely fit the side or toe of the shoe.

[0007] In view of the above-mentioned deficiencies of the existing wall-type bottom pressing machines, the inventors, based on their experience and accumulated technology in manufacturing various products, have studied ways to improve the above-mentioned deficiencies. After continuous research, experimental improvements, they have finally developed and designed the airbag mechanism of the wall-type bottom pressing machine of the present invention, which is expected to eliminate the deficiencies and deficiencies caused by the prior art. Summary of the invention

[0060] The airbag mechanism of the wall-type sole pressing machine of the present invention is the same as the existing one, and two sets of sole pressing mechanisms are arranged on the machine platform, and a pressing rod is arranged above each of the sole pressing mechanisms. The two pressing rods can be used to press the front and rear ends of the shoe uppers respectively, and the pressing rods can swing left and right; the interior of the sole pressing mechanism is provided with a side pressing mechanism that can press the side of the shoe, and a binding pressing mechanism that can press the toe and heel of the shoe. These same components are not the application focus of the present invention and will not be described in detail. The following is only an explanation of the application focus of the present invention with the accompanying drawings.

[0061] The air bag mechanism of the wall type bottom pressing machine of the present invention is different from the prior art in that the side pressing mechanism and the bundle pressing mechanism are both composed of a plurality of air bag units.

[0062] The air bag mechanism of the wall-type sole pressing machine of the present invention has a side pressing mechanism for pressing the side edge of the shoe, such as Figure 5 and Figure 6 The side pressure airbag unit 400 shown in the figure is composed of a plurality of side pressure airbag units 400. The compression mechanism used to compress the toe and heel of the shoe, such as Figure 7 and Figure 8 The compression airbag unit 500 is shown.

[0063] Please refer to Figure 5 and Figure 6 As shown in the figure, the side pressure airbag unit 400 includes a solid part 410 at the upper end and an airbag part 420 at the lower end. Fixers 431 and 432 for connecting the oil hydraulic cylinder and a connector 433 for inserting a high-pressure gas conduit (not shown in the figure) are integrally embedded in the solid part 410. A gas delivery channel 4331 communicating with the airbag part 420 is provided inside the connector 433, so that the high-pressure gas conduit can introduce gas into the airbag part 420 via the gas delivery channel 4331. When the airbag part 420 is filled with high-pressure gas, the expansion side 4201 can bulge outward to press against the side of the shoe.

[0064] As shown in the figure, a groove 440 is also provided below the side pressure airbag unit 400. The groove 440 is a side T-shaped groove located on the inner side of the airbag portion 420. The groove can be used to embed an external embedded device 450. The external embedded device 450 forms an outer ring portion 4502 around the main body 4501. The main body 4501 is provided with a plurality of connecting holes for connecting a bottom hydraulic cylinder (not shown in the figure). The outer ring portion 4502 is used to snap into the interior of the groove 440 to prevent it from falling off during the linkage process. Since the position where the bottom hydraulic cylinder is connected is located on the inner side of the airbag portion 420, the side of the shoe can be accurately pressed. The external embedded device 450 can be reused when the original side pressure airbag unit is damaged.

[0065] Please refer to Figure 7 and Figure 8 The body of the compression airbag unit 500 is a hollow air chamber 5001, with clamping ends 510 and 520 on both sides. A slot 530 is provided at the front end of the body. The slot 530 is a side T-shaped slot for an externally embedded connector 540 to be embedded. The front end of the externally embedded connector 540 is provided with a plurality of through holes for connection with an axial driving mechanism (not shown in the figure) to control the movement of the compression airbag unit 500. An air guide channel 550 is provided inside the externally embedded connector 540. A through hole 561 and 562 are provided at the upper and lower ends of the air guide channel 550, respectively. The through holes 561 and 562 are communicated with the hollow air chamber 5001 of the compression airbag unit 500. Thereby, high-pressure gas can be introduced into the hollow air chamber 5001 through the air guide channel 550 and the through holes 561 and 562. When the hollow air chamber 5001 is filled with high-pressure gas, the expansion side 5002 bulges outward to apply pressure to the head and heel of the shoe.

[0066] As described above, the airbag mechanism of the wall-type sole pressing machine of the present invention, the side pressure airbag unit 400 and the bundle pressure airbag unit 500 can be expanded and formed by introducing high-pressure gas, and then press the side of the shoe or the head and heel. Since the airbag unit is elastic, it can naturally adhere to the periphery of the shoe and then press, which can avoid wrinkles around the shoe that affect its appearance and force strength.

[0067] In summary, the airbag mechanism of the wall-type bottom pressing machine of the present invention does have an unprecedented innovative structure, which has not been seen in any publications, and there are no similar products on the market, so there is no doubt that it is novel. In addition, the unique features and functions of this creation are far beyond the reach of the existing technology, so it is indeed more progressive than the existing technology, and meets the provisions of the patent law of my country on the application requirements for creation patents, so a patent application is filed in accordance with the law.

[0068] It should be noted that the above is a preferred specific embodiment of the present invention. If the changes made according to the concept of the present invention do not exceed the spirit covered by the description and drawings, they should be within the scope of the present invention.
