[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Referring to the above-mentioned figures, the shoe drying and shaping device provided by this utility model includes a drying oven 1 and a door 2 hinged to one side of the drying oven 1. A heater 3 is provided at the bottom of the drying oven 1. Multiple circulating fans 4 are provided inside the drying oven 1. An exhaust fan is provided on the side wall of the drying oven 1. The exhaust fan is used to exhaust air when there is overheating or high humidity. A first motor 5 is provided on the drying oven 1. The rotating shaft 6 of the first motor 5 is inserted into the drying oven 1 and extends to the lower part of the drying oven 1. Multiple sets of brackets 7 are provided from top to bottom on the rotating shaft 6. Each set of brackets 7 has a door at both ends. An upward connecting rod 8 is provided, on which an adjustable shoe last 9 for fixing shoes is provided, with the sole of the adjustable shoe last 9 facing upward. The door 2 is provided with a handle 41 and a door lock. There are two circulating fans 4, one fixed to one side of the bottom of the oven 1 by a frame 43, and the other fixed to the other side of the top of the oven 1 by a frame 43. The heater 3 is a resistance heater 3. The wires 44 of the resistance heater 3 and the circulating fan 4 pass out of the oven 1 and are connected to an external power source for power supply. The lower end of the oven 1 is provided with multiple casters 45.

[0024] In this embodiment, the door 2 is opened, and the shoes to be dried and shaped are placed onto the adjustable shoe last 9. Then, the door 2 is closed, and the heater 3, circulating fan 4, and first motor 5 are turned on to dry and shape the shoes. The shoes rotate together with the support 7 and the shaft 6 of the first motor 5, preventing some shoes from being directly blown by hot air and ensuring more even heating. Since there is no turntable or flat plate 16, etc., used in the prior art to support the shoes, heat is not blocked, allowing the shoes to come into more comprehensive and even contact with the hot air, resulting in better drying effect and improved drying efficiency. Placing the shoes onto the adjustable shoe last 9 further enhances the shaping effect of the shoes. The adjustable shoe last 9 can be adjusted according to the shoe size to improve its applicability. With the sole facing upwards, the weight of the shoe sole presses onto the upper, resulting in better adhesion between the sole and the upper. The handle 41 facilitates opening and closing the door 2, and the lock on the door 2 allows for easy operation by the operator, preventing accidental operation by others. One circulating fan 4 is located at the bottom of one side of the oven 1, and the other at the top of the other side of the oven 1, circulating hot air and thus making the temperature distribution inside the oven 1 more uniform. The casters 45 facilitate the overall movement of the device. This device is also suitable for drying and shaping adhesive structures such as fabrics or patches with artistic graphic designs on the shoe surface, thereby making the adhesive structures such as fabrics or patches with artistic graphic designs adhere more firmly to the shoe upper, making them less likely to fall off, not only making the shoes more beautiful but also extending their service life.

The grooves 21 and the sealing ring 22 are coated with lubricating oil. The support 10 is welded to the oven 1. The support 10 is provided with a second guide sleeve 23 through which the rotating shaft 6 and the rotating shaft 13 of the second motor 11 pass. The second guide sleeve 23 is provided with a first bearing. The rotating shaft 6 and the rotating shaft 13 of the second motor 11 are fixed to the inner ring of the corresponding first bearing.

[0026] In this embodiment, the second motor 11 is started to drive the first gear 12 to rotate. The second gear 14 meshes with the first gear 12 and rotates together, thereby driving the first connecting rod 18 and the second connecting rod 19 to move together. The first connecting rod 18 and the second connecting rod 19 can drive the plate 16, the first motor 5 and its rotating shaft 6, the bracket 7, and the adjustable shoe last 9 to move up and down. This allows the shoes on the adjustable shoe last 9 to move up and down while rotating with the rotating shaft 6, further preventing some shoes from being directly blown by hot air and making the heating more even. The rotation of the shoes, shoe last, and bracket 7 can also disturb the airflow blown by the circulating fan 4 inside the oven 1, preventing localized heating. The first guide sleeve 20 makes the up and down movement of the rotating shaft 6 of the first motor 5 more stable and the structure more stable. The sealing ring 22 and the lubricating oil are used to seal and prevent hot air from escaping from the oven 1, and to make the rotation of the rotating shaft 6 of the first motor 5 smoother. The second guide sleeve 23 makes the rotating shaft 6 of the second motor 11 and the rotating shaft 13 more stable when rotating, and the structure is more stable.

An adjusting shaft 28 is movably installed in the vertical channel 26, extending out of the shoe last. The adjusting shaft 28 has a handwheel 29 at its outer end and a first bevel gear 30 at its inner end. A screw 31 extends out of the shoe last in the horizontal channel 27. The inner end of the screw 31 is located at a second bevel gear 32 that meshes with the first bevel gear 30. The front shoe last 24 has a slot 33 for inserting the screw 31. A nut 34, screwed to the screw 31, is fixed in the slot 33. Multiple second bearings 35 are installed in the vertical channel 26. The adjusting... The shaft 28 is fixed to the inner ring of the second bearing 35. Multiple third bearings 36 are provided in the transverse channel 27. The screw 31 is fixed to the inner ring of the third bearing 36. The end of the screw 31 in the slot 33 is provided with a baffle plate 37 that can abut against the nut 34. The rear shoe last 25 is provided with a guide positioning rod 38 facing the front shoe last 24. The front shoe last 24 is provided with a positioning groove 39 for inserting the guide positioning rod 38. Both the front shoe last 24 and the rear shoe last 25 are composed of left and right parts that are split in half along their length. The left and right parts are fixed by multiple bolts 40. The left and right parts separate the transverse channel 27, the vertical channel 26, the slot 33 and the positioning groove 39 in half, which facilitates the assembly of the shaft 28, the screw 31, the second bearing 35, the third bearing 36, the fourth bearing, the baffle plate 37 and the guide positioning rod 38.

[0028] In this embodiment, the adjustment shaft 28 is rotated by turning the handwheel 29. The adjustment shaft 28 drives the second bevel gear 32 and the screw 31 to rotate through the first bevel gear 30. The screw 31 and the fixed nut 34 cooperate to move the front shoe last 24 away from or closer to the rear shoe last 25, thereby adjusting the length of the adjustable shoe last 9 to fit shoes of different sizes, making it more versatile. The shoe last that fits the shoes also makes the shoes more shape-fixed. The front shoe last 24 and the rear shoe last 25 are both composed of left and right parts that are split in half along their length. The left and right parts are fixed by multiple bolts 40. The left and right parts also split the horizontal channel 27, the vertical channel 26, the slot 33 and the positioning slot 39 in half, which facilitates the assembly of the adjustment shaft 28, the screw 31, the second bearing 35, the third bearing 36, the fourth bearing, the blocking plate 37 and the guide positioning rod 38.
