A hanging shaft 2 is provided on the support structure 1, and a rotating bracket 3 is also included. The rotating bracket 3 is assembled on the support structure 1 and can rotate around the hanging shaft 2; in this embodiment, the rotating bracket 3 is connected to the support structure 1 through a universal rotating mechanism, and the universal rotating mechanism includes a fixed disk 201, a rotating disk 202 and a driving motor (not shown in the figure), the fixed disk 201 is connected to the support structure 1, the rotating disk 202 is assembled on the fixed disk 201 and driven to rotate by the driving motor, and the rotating bracket 3 is connected to the rotating disk 202.

The rotating bracket 3 is provided with a glue supply module 4, a glue coating element 5 and a glue coating motor 6 that drives the glue coating element 5 to work. The glue supply module 4 is connected to the external glue supply system through the preset glue supply flow channel 21 on the hanging shaft 2, which can not only continuously obtain the colloid required for gluing, but also effectively simplify the structure to avoid the outer diameter hose affecting the movement operation. In the embodiment in the figure, the hanging shaft 2 is penetrated inside the rotating bracket 3 to facilitate gluing and heating. The glue supply module 4 realizes the delivery of liquid hot melt glue to the glue coating element 5. In this embodiment, the glue supply module 4 is equipped with a corresponding heating element to ensure that the hot melt glue is in a better flow state, thereby ensuring the uniformity and consistency of the glue coating, and avoiding the waste of glue. The glue coating element 5 is dynamically contacted with the shoe material under the drive of the glue coating motor 6 to realize the work of gluing on the shoe material; and the glue coating trajectory of the glue coating element 5 is changed by the rotation of the rotating bracket 3.

The glue rotating wheel 41 is embedded in the glue groove cavity 12 preset in the support structure 1, and two glue scraping knives 13 are also provided on the support structure 1. The two glue scraping knives 13 are respectively close to the glue rotating wheel 41 and the glue coating element 5 to automatically control the amount of glue attached to the surface of the glue rotating wheel 41 and the glue coating element 5, ensuring uniform and consistent glue coating, and avoiding the waste of glue. The glue supply module 4 also has a vertically arranged glue control column 42, which is arranged above the glue rotating wheel 41 and axially connected with the hanging shaft 2.

The control element 43 is a prior art, and its working principle will not be described in detail here. This structure can achieve automatic control of glue supply and improve the operability of mechanical glue coating.

[0027] See also Figures 1 to 4As shown, in this embodiment, the gluing motor 6 is installed on the rotating bracket 3 in a horizontal position, and the gluing motor 6 leans on one side of the rotating bracket 3 and rotates with the rotating bracket 3, so that the rotation center of gravity of the rotating bracket 3 is lifted upward relative to the geometric center, thereby improving the rotation stability of the rotating bracket 3, avoiding rotational vibration, and ensuring the gluing quality; at the same time, the overall structural integrity of the gluing device is effectively guaranteed, and the service life is extended. Further, the power output by the gluing motor 6 is transmitted to the gluing element 5 and the glue rotating wheel 41 through the synchronous rotating shaft 7, and the synchronous rotating shaft 7 is installed on the rotating bracket 3, and the synchronous rotating shaft 7 and the gluing motor 6 are arranged on both sides of the axial direction of the hanging shaft 2. Preferably, the synchronous rotating shaft 7 is arranged in parallel with the gluing motor 6, effectively balancing the center of gravity of the rotating bracket 3, making the center of gravity close to the rotation center, and further improving the rotation performance of the rotating bracket 3. In this embodiment, the output end of the gluing motor 6 is provided with a first sprocket 61, and the synchronous rotating shaft 7 is coaxially provided with a second sprocket 71, a third sprocket 72, and a fourth sprocket 73.

Not only is the structure compact and reasonable, but it also optimizes the rotation center of gravity position of the rotating bracket 3, which is beneficial to the gluing work.

[0028] In addition to the above-mentioned transmission mode of the gluing motor 6 driving the gluing element 5, another transmission mode may be adopted. Figure 5 , 6In the manner shown, the output end of the gluing motor 6 is provided with a first sprocket 61, and the synchronous rotating shaft 7 is coaxially provided with a second sprocket 71, a third sprocket 72, and a first bevel gear 74. The first sprocket 61 and the second sprocket 71 are connected and driven by a chain, and the third sprocket 72 is connected to the fifth sprocket 81 by a chain, and the first bevel gear 74 is directly meshed with the second bevel gear 86; wherein, the fifth sprocket 81 is coaxially assembled with the rubber rotating wheel 41, and the second bevel gear 86 is mounted on the universal shaft 87, and the other end of the universal shaft 87 is provided with a third bevel gear 88, and the third bevel gear 88 is meshed with the fourth bevel gear 89, and the fourth bevel gear 89 is coaxially assembled with the gluing element 5. This structure also achieves that the gluing motor 6 synchronously drives the gluing element 5 and the rubber rotating wheel 41, and the structure is simple and convenient to manufacture. Similarly, the transmission routes of the third sprocket 72 and the first bevel tooth 74 are arranged on the left and right sides of the axial direction of the hanging shaft 2, and together with the gluing motor 6 and the synchronous rotating shaft 7, form a system distributed around the periphery of the hanging shaft 2. It is not only compact and reasonable in structure, but also optimizes the rotation center of gravity position of the rotating bracket 3, which is beneficial to the gluing work.
