Description

Airbag mechanism of wall-type bottom pressing machine

The present invention relates to an airbag mechanism, in particular to an airbag mechanism of a wall-type sole pressing machine, which is arranged inside the pressing groove of the wall-type sole pressing machine and is composed of a plurality of inflatable airbag units, and can perform a conforming pressing on the front, rear and sides of the shoe.

As shown in Figure 1, a general 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 materials. 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.

The upper and sole of the shoe are mainly pressed and bonded using a wall-type sole pressing machine as shown in Figures 2A, 2B, and 2C. The wall-type sole pressing machine 200 has two sets of sole pressing mechanisms 300 installed on the machine 201. A pressing rod 210, 220 is installed above each of the two sets of sole pressing mechanisms 300. The two pressing rods 210, 220 can be used to press the front and rear ends of the upper respectively. The pressing rods 210, 220 can also be swung left and right to facilitate the replacement of shoe materials.

Please refer to FIG. 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 has a plurality of side pressing blocks 303 inside, and the side pressing mechanism 301 drives a 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.

Please refer to Figure 4, the compression block 302 used to compress the toe and heel of the shoe is a solid rubber block; the side compression block 303 used to press the side of the shoe 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.

However, as the appearance of shoes becomes more and more diverse, the lines become more varied, and the types of curved surfaces around the soles also increase. When the curved surfaces on the sides of the soles become more and more varied, the traditional compression blocks or side compression blocks made of solid rubber are mostly pre-processed and fixed in shape, and the shape or strength cannot be changed temporarily. Therefore, it is easy for the adhesive surface to fail to adhere properly, 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.

In view of the above-mentioned shortcomings of conventional wall-type sole pressing machines, the inventors based on their experience and accumulated technology in manufacturing various products, studied ways to improve the above-mentioned shortcomings. After continuous research, experimental improvements, they finally developed and designed the airbag mechanism of the wall-type sole pressing machine of the present invention, hoping to eliminate the shortcomings and deficiencies caused by conventional sole pressing machines.

Therefore, the present invention aims to provide an air bag mechanism for a wall-type sole pressing machine, which utilizes an air bag pressing block unit to bond the sole and the upper of a shoe in various shapes.

According to the airbag mechanism of the wall-type sole pressing machine of the present invention, the airbag mechanism includes a side pressure airbag unit that can press the side of the shoe, and a compression airbag unit that can compress the toe and heel of the shoe. The side pressure airbag unit and the compression airbag unit are both inflatable and elastic, and can naturally conform to the arc or curved surface around the shoe. This is the second purpose of the present invention.

In order to help the review committee members to have a deeper understanding of the purpose, shape, structural device features and functions of the present invention, the following examples are given with diagrams to explain the structure of the present invention in detail as follows:

The air bag mechanism of the wall-type sole pressing machine of the present invention is the same as that of the known one, and two sets of sole pressing mechanisms are arranged on the machine. A pressing rod is arranged on the top of each sole pressing mechanism. The two pressing rods can be used to press the front end and the rear end of the shoe upper respectively, and the pressing rod 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 compression 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 elaborated here. The following is only an explanation of the application focus of the present invention with the help of drawings.

The air bag mechanism of the wall-type bottom pressing machine of the present invention is different from the conventional one in that the side pressing mechanism and the compression mechanism are both composed of a plurality of air bag units.

The air bag mechanism of the wall-type sole pressing machine of the present invention is used to press the side of the shoe, and is composed of a plurality of side pressure air bag units 400 as shown in Figures 5 and 6. The compression mechanism used to compress the toe and heel of the shoe is composed of the compression air bag unit 500 as shown in Figures 7 and 8.

Please refer to Figures 5 and 6. The side pressure airbag unit 400 includes a solid part 410 at the upper end and an airbag part 420 at the lower end. The solid part 410 is internally embedded with a fixing device 431, 432 for connecting to a hydraulic cylinder and a connector 433 for inserting a high-pressure gas conduit (not shown). The connector 433 is internally provided with a gas delivery channel 4331 communicating with the airbag part 420, so that the high-pressure gas conduit can introduce gas into the airbag part 420 through the gas delivery channel 4331. When the airbag part 420 is filled with high-pressure gas, its expanded side 4201 can bulge outward to fit against the side of the shoe.

As shown in the figure, a groove 440 is provided below the side pressure airbag unit 400. The groove 440 is a side T-shaped groove, which is located on the relatively inner side of the airbag part 420. It can be used to embed an external device 450. The external device 450 forms an outer ring part 4502 around the main body 4501. The main body 4501 is provided with a plurality of connection holes to connect a bottom hydraulic cylinder (not shown). The outer ring part 4502 can be inserted into the inside of the groove 440 to prevent it from falling off during the linkage process. Since the connection position of the bottom hydraulic cylinder is located on the relatively inner side of the airbag part 420, the side of the shoe can be accurately pressed. The external device 450 can be reused when the original side pressure airbag unit is damaged.

As shown in Figures 7 and 8, the body of the compression airbag unit 500 is a hollow air chamber 5001, with clamping ends 510 and 520 on both sides. The front end of the body is provided with a slot 530, which is a side T-shaped slot for an externally embedded connector 540 to be inserted. The front end of the externally embedded connector 540 is provided with a plurality of through holes for connecting with an axial drive mechanism (not shown) to control the movement of the compression airbag unit 500. The internal part of the externally embedded connector 540 is provided with an air guide channel 550, and the upper and lower ends of the air guide channel 550 are respectively provided with a through hole 561 and 562, and the through holes 561 and 562 are communicated with the hollow air chamber 5001 of the compression airbag unit 500. Thus, high-pressure gas can be introduced into the hollow air chamber 5001 through its air guide channel 550, through holes 561, 562. When the hollow air chamber 5001 is filled with high-pressure gas, its expansion side 5002 bulges outward to compress the toe and heel of the shoe.

As described above, the airbag mechanism of the wall-type sole pressing machine of the present invention, its side pressure airbag unit 400 and the compression 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 to press, which can prevent the periphery of the shoe from wrinkling and affecting its beauty and force strength.

In summary, the airbag mechanism of the wall-type sole pressing machine of the present invention does have an unprecedented innovative structure. It has not been seen in any publication, and there are no similar products on the market. Therefore, there is no doubt that it is novel. In addition, the unique features and functions of this creation are far beyond the comparison of common use, so it is indeed more advanced than common use, and it meets the requirements of the application requirements of the patent law of the Republic of my country for creation patents, and a patent application is filed in accordance with the law.

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 still do not exceed the spirit covered by the instructions and diagrams, they should be stated within the scope of the present invention.
