[0038] The control unit 2 is installed on the frame 1 and is respectively connected to the conveying component 3, the heat setting component 4, the cold setting component 5 and the linkage grasping and transferring component 6;

[0039] The conveying component 3 includes a first conveying structure 31, a second conveying structure 32 and a centralized blanking conveying structure 33.

Such a modular design layout saves the equipment space utilization rate and development cost, facilitates processing at multiple workstations, and thus facilitates simultaneous operation at multiple workstations, greatly improving production capacity, saving space, and enhancing production efficiency.

[0045] Meanwhile, in this embodiment, by setting the linkage grasping and transferring assembly 6, synchronous grasping and translation can be achieved, effectively saving space and simultaneously effectively improving production capacity.

[0047] In this embodiment, it is specifically shown that the conveying structure adopted is a conveyor belt, which has a simple structure, stable conveying, and baffle members 34 are arranged on the conveyor belts on both sides. During the shaping process, if the workstations at the rear end have not completed processing, the baffle members 34 are used for blocking until the workstations at the rear end complete processing, and then the shoe materials to be shaped are released. This process is repeated to complete stable processing.

[0048] In this embodiment, specifically, the conveyor belts on both sides can respectively convey and process the left and right feet of the shoe materials, thereby realizing synchronous processing and shaping of a pair of shoes to better improve processing efficiency.

[0050] In this embodiment, the heating tube 421 can specifically be multiple copper heating tubes 421 to better perform heating and shaping.

[0051] In some embodiments, the adjustable hot pressing structure 43 includes a first translation member 431, a first connecting seat 432, a first left lifting member 433, a first right lifting member 434, a first front lifting member 435, a first rear lifting member 436, and a hot pressing die 437.

[0052] In this embodiment, the setting of the adjustable hot press-fitting structure 43 is specifically shown. Its structure is simple and reasonably designed. When adjusting the position, through four jacking structures, the front-up, back-up, and left-right height adjustment of the hot press-fitting die 437 can be realized, so that the hot press-fitting die 437 can better wrap the toecap to be shaped.

[0056] The structure of this embodiment is simple and reasonably designed. When adjusting the position, through four jacking structures, the front-up, back-up, and left-right height adjustment of the cold press-fitting die 537 can be realized, so that the cold press-fitting die 537 can better wrap the toecap to be shaped. For shoe materials with different placement angles and positions, better wrapping and shaping can also be realized. The adjustment of this embodiment is convenient, the alignment accuracy is high, and with the angle detection of the CCD vision positioning structure 538, the precise position adjustment of the cold press-fitting die 537 can be realized, so as to facilitate better tightening and positioning and be compatible with the toecap shaping of different shoe models.

[0059] In some embodiments, the linkage grasping and transferring assembly 6 is provided with a fixed frame 61, a moving mechanism 62, a first grasping mechanism 63, a second grasping mechanism 64, and a third grasping mechanism 65. The fixed frame 61 is installed on the frame 1. The moving mechanism 62 is installed on the fixed frame 61 and is respectively drivingly connected to the first grasping mechanism 63, the second grasping mechanism 64, and the third grasping mechanism 65 through a drag chain drive structure to realize the linkage drive of the first grasping mechanism 63, the second grasping mechanism 64, and the third grasping mechanism 65.

[0060] Specifically, the first grasping mechanism 63 is provided with a lifting structure 631, a screw rotation structure 632, a translation structure 633, and a jaw structure 634.

The translation structure 633 is connected to the screw rotation structure 632. The jaw structure 634 is installed on the translation structure 633.

[0061] In this embodiment, the structural settings of the linkage grasping and transferring assembly 6 are specifically shown. During its use, the three grasping mechanisms can act synchronously. The first grasping mechanism 63 grasps the shoe materials on the conveying structure. The second grasping mechanism 64 grasps the shoe materials on the heat setting assembly 4. The third grasping structure grasps the shoe materials on the cold setting assembly 5, then translates and places them, and then translates and resets to wait for the next grasping operation. In this embodiment, it is equivalent to adopting three grasping structures to perform grasping and placing in a linkage manner similar to a shift fork. It occupies a small space itself and has a high grasping and placing efficiency, which can effectively improve production efficiency.

[0062] Specifically, in the above embodiments, the structural settings of the first grasping mechanism 63, the second grasping mechanism 64, and the third grasping mechanism 65 are the same.

[0063] In this embodiment, the rotating structures of three of the grasping mechanisms are all set as horizontal rotating structures. In order to achieve a better placement effect, the second grasping mechanism 64 is further provided with a vertical rotating structure. With such a setting, since the angles and directions of the shoe materials to be grasped are uncertain, through rotational adjustment, after the placement direction is correct, the placement can be carried out. Such a setting has good compatibility with the shoe materials, good grasping and placement effects, and is also convenient for positioning during heat setting and cold setting. The structure of this embodiment is simple, can achieve linkage operation, improve efficiency, and save space. By providing lifting, rotation, translation, and clamping jaws in the grasping mechanism, it can be compatible with the uppers of different shoe types for grasping and adjusting the placement, is convenient for picking and placing, and has high production efficiency.
