Description

Technical Field

[0001] This utility model relates to the technical field of hanging drying machines, specifically a foldable leather hanging drying machine. Background Technology

[0002] The foldable leather hanging dryer is a device that combines portability and professional leather drying functions. It has built-in low-power heating elements, such as PTC ceramic heating elements and centrifugal fans, which blow constant-temperature hot air of 40-60℃ evenly onto the leather surface through the air duct to accelerate moisture evaporation. The foldable leather hanging dryer uses a constant temperature control of 45-55℃ to avoid the hardening or discoloration of leather caused by traditional high-temperature drying, while preserving the natural oils and suppleness. The support plates, hooks, and other support components of foldable leather hanging dryers are generic, with a single shape and limited adjustment range. They cannot match the special contours of shoes. The softness of leather shoes depends on the natural oils in the leather fibers. Without internal support, when the toe and the shaft of the shoe droop, the leather fibers are continuously stretched. During the hot air drying process, the stretched fibers will solidify and take shape. The oils are excessively removed with the evaporation of moisture, causing the leather to change from soft and elastic to stiff and brittle, resulting in leather deformation and shortening the lifespan of the shoes. Therefore, a foldable leather hanging dryer is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-8 This utility model provides a technical solution: A foldable leather hanging dryer includes a dryer 1 with a built-in PTC ceramic heating element and a centrifugal fan. Folding mechanisms 2 are rotatably connected to both sides of the dryer 1. A damping plate 5 is fixedly connected to one end of the folding mechanism 2, and a hanging device 3 is slidably connected to the outer side of one end of the folding mechanism 2. Air outlet meshes 4 are provided on both sides of the hanging device 3. The hanging device 3 includes a hanging rack 31, with mounting grooves 32 on both the upper and lower sides. Elastic retaining rings 33 are fixedly connected to the center positions of both sides of the hanging rack 31. Ball bearings 34 are provided on the inner sides of the center positions of both sides of the hanging rack 31. An adaptable bracket 35 is fixedly connected to the inner side of the mounting grooves 32, and a support plate 36 is fixedly connected to the upper end of the adaptable bracket 35. The adaptable bracket 35 includes a fixing plate 351, with a return spring 352 fixedly connected to the outer side of one end of the fixing plate 351. A crank 353 is fixedly connected to the outer ring of the return spring 352, and the other end of the crank 353 is fixedly connected to a connecting rod 354 via the return spring 352.

[0017] It should be noted that: the support plate 36 includes a plate body 361, a limiting block 362 is fixedly connected to the bottom of the plate body 361, ventilation holes 363 are opened on the inner side of the plate body 361, the outer side of the limiting block 362 is engaged with the inner side of the elastic retaining ring 33, one side of the plate body 361 is arc-shaped, the length of the plate body 361 is adapted to the length of the hanging rack 31, and the ventilation holes 363 are evenly and equidistantly distributed inside the plate body 361.

[0018] Specifically: The 361 board has an arc-shaped design on one side, which fits the curved contour of three-dimensional items such as leather shoes, avoiding the problem of items slipping due to traditional flat boards, while reducing the pressure and friction on the leather surface and protecting the leather material from damage.

[0019] Furthermore: the outer side of the limiting block 362 engages with the inner side of the elastic retaining ring 33, realizing the quick fixing and unlocking of the support plate 36: in the initial state, the engagement ensures that the support plate 36 is stable and ready, and in use, the fixing can be released by the squeezing of the ball 34. No additional tools are required for operation, which improves the convenience of the equipment.

[0020] As a further implementation of the above technical solution: there are two folding mechanisms 2, which are symmetrically distributed about the vertical center line of the dryer 1. A damping shaft is provided at the rotational connection between the folding mechanism 2 and the dryer 1.

[0021] It should be noted that there are two mounting slots 32, each with a length consistent with the length of the hanging rack 31, allowing the outer side of the bracket 35 to fit against the inner wall of the mounting slot 32. Ball bearings 34 are evenly distributed on the inner sides of both sides of the hanging rack 31, with one ball bearing 34 protruding from the inner wall of the hanging rack 31. The outer side of the ball bearing 34 is tightly fitted against the inside of the hanging rack 31. The upper ball bearing 34 contacts the limiting block 362. There are two cranks 353, which are fixedly connected to both ends of the return spring 352 via a rotating shaft. One end of the fixing plate 351 is rotatably connected to one end of the crank 353 and the connecting rod 354. The two cranks 353 are rotatably connected to each other, allowing the bracket 35 to adjust within a range of 0°-30°. The spring force of the return spring 352 is 8N.

[0022] Specifically, one of the ball bearings 34 protrudes from the outer side of the inner wall of the drying rack 31, ensuring that the drying device 3 can contact the damping plate 5 first when it slides. The protruding part concentrates the pressure of the damping plate 5, avoiding the unlocking delay caused by pressure dispersion. The pressure is orderly transmitted to the limit block 362 through the evenly distributed ball bearings 34, making the unlocking process smooth and controllable, avoiding damage to the limit block 362 or the elastic retaining ring 33 due to excessive local force, and improving the fitting accuracy and service life of the components.

[0023] Furthermore, there are two cranks 353, which are fixedly connected at both ends by return springs 352 to form a double crank 353 linkage structure. When the support plate 36 is subjected to pressure from an object, the two cranks 353 can rotate inward or outward simultaneously. The pressure is absorbed by the deformation of the return springs 352, which can distribute the force more evenly and prevent the cranks 353 on one side from being overloaded and breaking.

[0024] Work process: In the initial state, the folding mechanism 2 is in a retracted state and attached to both sides of the dryer 1. Since the folding mechanism 2 and the dryer 1 are rotatably connected and the connection is equipped with a damping shaft, the unfolding angle can be slowly adjusted by the damping force during the rotation. Hold both ends of the hanging rack 31 with both hands and pull it outward. During the process of sliding the hanging rack 31 to the appropriate position on the folding mechanism 2, the damping plate 5 will squeeze the protruding ball 34. The ball 34 that are in close contact with each other will be squeezed upward in sequence. At the same time, it will squeeze the outside of the limiting block 362. As the thrust increases, the limiting block 362 will be squeezed out of the inner side of the elastic retaining ring 33. The elastic retaining ring 33 will be slightly deformed by the squeezing of the limiting block 362, and the adaptable bracket 35 will unfold according to the elastic force of the return spring 352. After the limiting block 362 is completely disengaged, it will return to its original state. When placing leather shoes to be dried, place the heel or upper of the shoe close to the plate 361 and apply downward or sideways pressure to the plate 361. Under pressure, the connecting rod 354 drives the cranks 353 at both ends to rotate around the connection point with the fixed plate 351 at a certain angle. When the two cranks 353 rotate, they will stretch or compress the return springs 352 at both ends. The deformation of the return springs 352 will generate a reverse elastic force, so that the cranks 353 and the connecting rod 354 maintain a stable angle, thereby driving the plate 361 of the support plate 36 to fit tightly against the surface of the item, adapting to leather products of different sizes and shapes. The ventilation holes 363 evenly distributed on the inner side of the plate 361 are fully exposed, with no dead corners blocked by the items, reserving a channel for subsequent hot air circulation. The air outlet mesh holes 4 on both sides of the hanging rack 31 form a corresponding path with the ventilation holes 363 of the plate 361, ensuring that the hot air can cover the inside of the item.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
