Technical Field

[0001] This utility model relates to the field of jig technology, specifically to a shoe sole coating jig. Background Technology

[0002] In the modern footwear industry, sole coating technology has become increasingly important to meet consumers' diverse needs for sole performance and appearance. Abrasion-resistant coatings can significantly extend the lifespan of soles, allowing them to withstand prolonged friction in various complex terrains; waterproof coatings can effectively prevent moisture penetration, keeping the sole and inside the shoe dry and improving wearing comfort; and aesthetically pleasing coatings can add a unique visual effect to the sole, enhancing the product's market competitiveness.

[0003] However, currently, most shoe sole coating processes utilize individual production fixtures. This traditional production model has numerous drawbacks, significantly limiting production efficiency. Firstly, individual operations consume substantial time and labor costs, as only a single sole can be coated at a time, resulting in a lengthy overall production cycle that fails to meet the demands of large-scale production. Secondly, consistency in manual operations is difficult to guarantee; different operators may differ in placing the sole and adjusting coating parameters, affecting the stability of coating quality and leading to inconsistent product quality.

Detailed Implementation

[0018] 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.

[0019] As shown in Figures 1 to 4, this invention provides a shoe sole coating fixture, primarily composed of a central drive mechanism 1 and a support frame 2 surrounding it. Numerous shoe racks 3 are mounted on the support frame 2, connected to the central drive mechanism 1 to ensure that the central drive mechanism 1 can drive all shoe racks 3 to rotate synchronously. This fixture is mainly used in evaporative coating processes, in which gaseous coating material is sprayed from below the central drive mechanism 1 and subsequently deposited on the shoe sole surface to form a coating. The multiple shoe racks 3 on the support frame 2 surrounding the central drive mechanism 1 can handle a large number of shoe soles at once, significantly improving production efficiency compared to the traditional method of producing soles one by one. Furthermore, the central drive mechanism 1 can drive all shoe racks 3 to rotate continuously, resulting in more uniform adhesion of the coating material to the shoe sole, effectively improving the quality and consistency of the coating.

[0020] In this embodiment, the central drive mechanism 1 adopts a ring-shaped toothed disc 101 design. The shoe racks 3 are arranged in an orderly manner around the toothed disc 101, with one end firmly mounted on the support 2 and meshing with the toothed disc 101. When an external power source applies power to drive the toothed disc 101 to start rotating, the rotation of the toothed disc 101 can smoothly drive all the shoe racks 3 to rotate through the meshing action, thereby achieving all-round uniform coating of the sole during the coating process.

[0021] The support frame 2 includes a tray 201. The aforementioned central drive mechanism 1 is mounted at the center of the tray 201, and several slots 202 are provided around the periphery of the tray 201. These slots 202 can secure one end of the shoe rack 3, providing stable support for the shoe rack 3. In addition, the support frame 2 also includes a ring frame 203, which is located outside the tray 201 and serves to secure the other end of the shoe rack 3. This design combining the tray 201 and the ring frame 203 makes full use of space, maximizing the utilization of the area, allowing more shoe racks 3 to be placed in a limited space, further improving production efficiency. Meanwhile, the height of the ring frame 203 is lower than that of the tray 201, allowing the soles to be stacked diagonally on the shoe rack 3. The angles and durations of contact between the various surfaces of the diagonally stacked soles and the gaseous coating material sprayed from below the central drive mechanism 1 are more diverse, which helps the gaseous coating material to cover the sole surface more comprehensively. This reduces the uneven coating problem that may be caused by a single placement angle of the soles, making the thickness and quality distribution of the coating more uniform, thereby improving the product yield. At the same time, diagonal stacking can place more soles in a limited space. Compared with horizontal stacking, it utilizes space that might otherwise be wasted, further increasing the load-bearing capacity of soles in a single coating and improving overall production efficiency.

[0022] The shoe rack 3 includes a head-end fixing rod 301 and a tail-end fixing rod 303. The head-end fixing rod 301 is securely mounted on the tray 201 via a bearing seat, and a driven gear 302 is provided on the head-end fixing rod 301. This driven gear 302 meshes with the gear plate 101 to ensure accurate power transmission. The tail-end fixing rod 303 is mounted on the ring frame 203, providing support for the shoe rack 3 in another direction. A first waist support 304 is fitted onto the head-end fixing rod 301, and a bearing is installed between the first waist support 304 and the head-end fixing rod 301 to ensure flexible rotation between them. A second waist support 305 is also installed on the tail-end fixing rod 303, and the first waist support 304 and the second waist support 305 are fixedly connected by two pull rods 306. In this way, the first waist support 304, the second waist support 305, and the pull rods 306 together form a stable fixing frame. Within this fixed frame, a specially designed movable frame is incorporated. This movable frame is easily detachable from the fixed frame and can rotate freely. The movable frame mainly consists of a rotating plate 307, a first template 308, and a second template 309. The rotating plate 307 is connected to the head-end fixing rod 301. The first templates 308 are spaced apart on the rotating plate 307 and secured to it by two screws 3010. By cleverly adjusting these two screws 3010, the distance between the first template 308 and the rotating plate 307 can be easily changed. The second template 309 is mounted on the second waist support 305, and a bearing is also installed between the second template 309 and the second waist support 305 to allow for flexible rotation. With this design, when the head-end fixing rod 301 is driven by the gear disc 101 to rotate, the first templates 308 and the second template 309 will rotate synchronously, and the sole requiring coating will be securely clamped between the first templates 308 and the second template 309. Since the distance between the first template 308 and the rotating plate 307 is adjustable, the distance between the first template 308 and the second template 309 will also change. During the coating process, the shoe sole is first stacked and placed between the first template 308 and the second template 309. Then, by precisely adjusting the first template 308, the first template 308 and the second template 309 can tightly clamp the shoe sole, ensuring the stability of the shoe sole during the coating process.

[0023] In this embodiment, the shoe rack 3 is divided into two types, A and B, according to actual production needs. Although the two types of shoe racks 3 are consistent in overall structure, they differ in detailed design. Type A shoe racks 3-A are mainly arranged closely according to the space between the tray 201 and the ring frame 203. Type B shoe racks 3-B, on the other hand, are designed to further increase processing capacity by deliberately reducing the distance between the first template 308 and the second template 309. This design allows Type B shoe racks 3-B to cleverly fill the gaps in Type A shoe racks 3-A, thereby placing more shoe soles in a limited space and significantly improving production efficiency.

[0024] In addition, the shoe rack 3 is equipped with several modules specifically designed according to the shape of the shoe soles. These modules play an important role in the sole coating process. They are sandwiched between shoe soles, effectively separating them to prevent collisions or adhesion during coating and enabling precise positioning of the soles. These modules mainly include a head module 401, a tail module, and a middle module 402. The head module 401 and tail module are mainly used to cooperate with the first template 308 and the second template 309. Each of them has a positioning post on one side, which can be accurately inserted into the first template 308 and the second template 309 to achieve precise positioning of a stack of shoe soles. The two surfaces of the middle module 402 are provided with positioning protrusions, which can fit tightly with specific parts of the shoe sole surface, further ensuring the accurate positioning of the shoe soles during the coating process.
