Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Please see Figures 1-5 An adjustable shoe upper pressing and shaping device includes a base assembly 1, which includes a base body 11. The rear end of the base body 11 has a steam tank 12 with an open top. A steam emitting plate 13 is embedded in the opening of the steam tank 12. A steam delivery pipe 14 is inserted into a vertical side wall of the base body 11 and connects to the inside of the steam tank 12. The other end of the steam delivery pipe 14 is connected to an external steam generator. Steam is delivered from the steam delivery pipe 14 to the steam tank 12 and then emitted by the steam emitting plate 13. This structure not only prevents the shoe upper from being damaged by high temperature, but also softens the shoe upper material with water vapor, improving its shaping effect. A conveyor belt 15 is provided on the top surface of the base body 11 in front of the steam emitting plate 13. A pressing and shaping mechanism 2 is provided above the steam emitting plate 13. A cooling mechanism 3 is also provided on the top surface of the base body 11 at the corresponding position of the conveyor belt 15. The pressed and shaped shoe upper is pushed onto the conveyor belt 15 and then undergoes accelerated cooling treatment by the cooling mechanism 3. The entire workflow of this embodiment is completed.

[0028] In this embodiment, the pressing and shaping mechanism 2 includes a shoe last 21 covering the steam emitting plate 13. The shoe last 21 has a cavity structure, and several through holes are evenly opened on the side wall of the shoe last 21 for venting steam. The through holes are designed to allow steam to adhere to the shoe upper placed on the shoe last 21. A receiving hole is opened in the center of the front side wall of the shoe last 21. A pressing sleeve 23 that can be raised and lowered and whose shape and size are adapted to the shoe last 21 is slidably sleeved on the outer side of the shoe last 21. The side wall of the pressing sleeve 23 is embedded with... A heating wire 24 is provided, which can improve the shaping effect of the shoe upper. The pressing and shaping mechanism 2 also includes a mounting bracket 26 fixedly connected to the top surface of the base body 11. The bottom surface of the horizontal section of the mounting bracket 26 is connected to the pressing sleeve 23 through a vertical electric push rod 25. A pushing component 22 extending forward to the outside is provided in the center of the shoe last 21. The setting of the pushing component 22 can improve the working efficiency of this embodiment, and at the same time avoid the accidental burn caused by the high temperature of the shoe upper when manually removing the shoe.

[0029] Specifically, the shoe upper to be pressed and shaped is placed on the shoe last 21. At this time, the steam conveying equipment is turned on, and steam is conveyed to the steam tank 12 through the steam conveying pipe 14, and then emitted into the shoe last 21 through the steam emitting plate 13. Finally, the steam is emitted through the through hole to wet the shoe upper to be pressed and shaped. Then, the switch of the heating wire 24 is turned on to heat up the pressing sleeve 23. Then, the vertical electric push rod 25 is started to extend towards the shoe last 21, and the pressing sleeve 23 also moves towards the shoe last 21 until the pressing sleeve 23 is tightly pressed against the surface of the shoe upper to be pressed and shaped. The vertical electric push rod 25 stops working. After a period of time, when the shoe upper has achieved the pressing and shaping effect, the vertical electric push rod 25 is started again to retract upward until it completely leaves the surface of the shoe upper. Then, the pushing component 22 is started to push the shoe upper onto the conveyor belt 15. The conveyor belt 15 sends the shoe upper to the cooling mechanism 3 for cooling and shaping treatment.

[0030] It should be explained in detail that the pushing component 22 includes a horizontal electric push rod 221 that is fixedly connected to the rear wall of the shoe last 21 and whose inner push rod can pass through the receiving hole to reach the outside. The setting of the horizontal electric push rod 221 realizes the automated operation of this embodiment, avoids the lag of manual operation, improves its work efficiency, and also avoids the accidental burn caused by the high temperature of the shoe surface when manually picking up the shoe. The front end of the inner push rod of the horizontal electric push rod 221 is fixedly provided with a push plate 222 that can be retracted into the receiving hole. After the shoe surface is pressed and shaped, the horizontal electric push rod 221 is activated to extend it towards the conveyor belt 15. The push plate 222 drives the shoe surface to extend forward until it is pushed onto the conveyor belt 15. The conveyor belt 15 then sends the shoe surface to the cooling mechanism 3 for cooling and shaping.

[0031] In this embodiment, the cooling mechanism 3 includes at least four support columns 31 fixedly connected to the top surface of the base body 11 at the outer edge of the conveyor belt 15. The top surfaces of the support columns 31 are connected to the same mounting plate 32. The cooling mechanism 3 also includes a drive assembly 33 mounted on the mounting plate 32. The drive assembly 33 includes a motor 331 fixedly mounted on the top surface of the mounting plate 32. The output shaft of the motor 331 passes through the mounting plate 32 and is coaxially fixedly connected to a drive gear 332. A driven gear 334 is rotatably connected to the bottom surface of the mounting plate 32 at the end furthest from the drive gear 332. The drive gear 332 and the driven gear 334 are connected by a chain 333. The bottom surface of the 33 is provided with several mounting rods 34 at equal intervals. The bottom end of the mounting rods 34 is hinged to a cooling fan 35. The angle of the hinged cooling fan 35 can be adjusted according to the actual required airflow range and direction, which improves the applicability of this embodiment. When the shoe upper that needs to be cooled is transported into the cooling mechanism 3, the airflow angle of the cooling fan 35 is adjusted according to the characteristics of the shoe upper structure. Then, the motor 331 is turned on to drive the drive gear 332 to rotate. The drive gear 332 rotates under the transmission action of the chain 333 to drive the driven gear 334. Thus, the cooling fan 35 rotates with the reciprocating rotation of the chain 333, thereby cooling the shoe upper without dead angles.

[0032] Furthermore, when the horizontal electric push rod 221 extends to its longest position, the push plate 222 moves above the conveyor belt 15, ensuring that the push plate 222 can push the shoe upper onto the conveyor belt 15, and then smoothly transport it to the cooling mechanism 3 for cooling. When the horizontal electric push rod 221 retracts to its shortest position, the push plate 222 retracts completely into the receiving groove, ensuring that the inner wall of the shoe upper can fit tightly against the outer wall of the shoe last 21, improving the pressing and shaping effect. When the vertical electric push rod 25 extends to its longest position, the inner wall of the pressing sleeve 23 abuts against the outer wall of the shoe last 21, ensuring that the outer surface of the shoe upper and the inner wall of the pressing sleeve 23 can fit tightly against each other, improving the pressing and shaping effect.

[0033] Furthermore, the top surface of the base body 11 can be provided with multiple steam tanks 12 that do not affect each other's work, as well as steam emission plates 13, steam conveying pipes 14, and conveyor belts 15 that work together with them. Then, a pressing and shaping mechanism 2 and a cooling mechanism 3 with the same number and one-to-one position as the aforementioned structural components can be provided accordingly. Such a configuration can greatly improve the working efficiency of this embodiment.

[0034] Finally, it should be noted that the conveyor belt 15, horizontal electric actuator 221, vertical electric actuator 25, and motor 331 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0035] Working Principle: In this embodiment, the worker places the shoe upper to be pressed and shaped on the shoe last 21. The steam delivery device is then turned on, and steam is delivered from the steam delivery pipe 14 to the steam tank 12, then emitted from the steam emission plate 13 into the shoe last 21, and finally emitted through the through-hole to wet the shoe upper. The heating wire 24 is then turned on, causing the pressing sleeve 23 to heat up. Next, the vertical electric actuator 25 is activated, extending it towards the shoe last 21. The pressing sleeve 23 moves accordingly until it is tightly pressed against the surface of the shoe upper. The vertical electric actuator 25 then stops working. After a period of time, when the shoe upper has achieved the desired pressing and shaping effect, the process is restarted. The vertical electric actuator 25 retracts upwards until it completely leaves the surface of the shoe upper. Then, the horizontal electric actuator 221 is activated to extend it towards the conveyor belt 15. The push plate 222 drives the shoe upper to extend forward until it is pushed onto the conveyor belt 15. When the conveyor belt 15 delivers the shoe upper to the mounting plate 32 in the cooling mechanism 3, the blowing angle of the cooling fan 35 is adjusted according to the characteristics of the shoe upper structure. Then, the motor 331 is turned on to drive the drive gear 332 to rotate. The rotation of the drive gear 332 drives the driven gear 334 under the transmission action of the chain 333. Thus, the cooling fan 35 rotates along with the reciprocating rotation of the chain 333, thereby providing a thorough cooling treatment for the shoe upper.
