[0002] In the process of shoe processing and production, in order to increase the aesthetics of the finished shoes, the outer surface of the finished shoes is usually sprayed with paint so that the outer surface of the finished shoes has an appearance of different colors or patterns. However, the existing method is usually to spray the outer surface of the finished shoes with a manual handheld spray gun. The manual spraying method is time-consuming and labor-intensive, and the spraying efficiency is low, and the uniformity of the spraying is difficult to ensure, which in turn affects the production efficiency of the finished shoes and the appearance quality of the shoes. Therefore, the use of an intelligent manipulator to drive a spray gun for automatic spraying is of great positive significance. In order to ensure the smooth progress of automatic spraying, corresponding clamps are required to clamp the finished shoes. How to propose a finished shoe spraying clamp that can stably clamp the finished shoes during the automatic spraying process and ensure the spraying effect and is convenient and easy to take and put the finished shoes is the technical problem to be solved by this application.

DETAILED DESCRIPTION

[0021] The present invention is further described below through specific implementation methods.

[0022] like Figures 1 to 5 As shown, the fixture for painting finished shoes described in the utility model comprises a rotating seat 1, an intermittent rotating driving mechanism 2, a bottom clamping seat 3 and a pressing last 4.

[0023] The rotating seat 1 is rotatably mounted on the rotating frame 5, the intermittent rotating driving mechanism 2 is arranged on the rotating frame 5 and is used to drive the rotating seat 1 to rotate intermittently, the bottom clamp seat 3 is connected to the upper end of the rotating seat 1, the bottom clamp seat 3 is used to place the detachable finished shoe 6 and shield the bottom surface of the sole of the finished shoe 6, effectively preventing the paint from being sprayed onto the bottom surface of the sole of the finished shoe 6 during the painting process, the pressing last 4 is detachably sleeved in the shoe cavity of the finished shoe 6 and is used to press the finished shoe 6 by its own weight, so that while stably pressing the finished shoe 6, the outer surface of the upper and the outer peripheral surface of the sole of the finished shoe 6 can be well exposed to the outside, In order to facilitate painting and better ensure the painting effect, the last 4 together with the finished shoe 6 can be easily removed from the bottom clamp seat 3, so as to facilitate the easy placement of the finished shoe 6. The top surface of the bottom clamp seat 3 is provided with an engaging groove 31 adapted to the bottom of the sole of the finished shoe 6 to ensure that the sole of the finished shoe 6 is stably placed in the bottom clamp seat 3, and the last 4 itself has a certain weight to ensure that the last 4 stably presses the finished shoe 6, further ensuring that the last 4 together with the finished shoe 6 will not be separated from the bottom clamp seat 3 during the painting and rotation process, thereby achieving stable clamping of the finished shoe 6 during the automatic painting process.

[0024] A rotating shaft 71 is fixedly provided at the center of the bottom end surface of the rotating seat 1, and a rotating hole is provided on the rotating frame 5. The rotating shaft 71 is rotatably installed in the rotating hole of the rotating frame 5 through a bearing 72, thereby facilitating the rotating connection between the rotating seat 1 and the rotating frame 5.

[0025] The intermittent rotation drive mechanism 2 is used to drive the rotating seat 1 to intermittently rotate 120 degrees each time. The intermittent rotation drive mechanism 2 includes a servo motor 21, a motor seat 22 and a coupling 23. The servo motor 21 is fixedly mounted on the motor seat 22, and the motor seat 22 is fixedly mounted on the bottom end surface of the rotating frame 5. The lower end of the rotating shaft 71 extends downward and passes through the bottom surface of the rotating frame 5. The motor shaft of the servo motor 21 is connected to the lower end of the rotating shaft 71 through the coupling 23. By controlling the servo motor 21 to rotate 120 degrees each time, the rotating seat 1 can be driven to perform an intermittent rotation of 120 degrees, so that the finished shoe 6 follows the rotation of 120 degrees. In this way, during the entire painting process of the finished shoe 6, the finished shoe 6 needs to be rotated 3 times to achieve a complete painting of the entire circle of the outer circumference of the finished shoe 6.

[0026] The rotating seat 1 includes a U-shaped bottom frame 11 , and a connecting plate 12 is fixedly disposed at an open end of the U-shaped bottom frame 11 .

[0027] The bottom clamp seat 3 is detachably connected to the rotating seat 1 through a locking mechanism 8, thereby facilitating the replacement of the bottom clamp seat 3, and at the same time, the last 4 can be replaced together, and replaced with a structure of different styles or sizes to adapt to the painting operation of finished shoes 6 of different styles or sizes. The locking mechanism 8 includes a locking stud 81 and a locking nut 82. At least one locking stud 81 is fixedly provided on the bottom end surface of the bottom clamp seat 3, and at least one locking hole 121 matched with the locking stud 81 is provided on the connecting plate 12. The lower end of the locking stud 81 passes through the locking hole 121 and is threadedly connected to the locking nut 82. The disassembly and assembly is simple and convenient, and when locked and fixed, the stability of the installation position of the bottom clamp seat 3 can be effectively ensured. Preferably, the number of the locking stud 81 and the locking hole 121 are both two and are arranged in one-to-one correspondence.

[0028] Two symmetrical holding grooves 41 are arranged on the outer peripheral surface of the top of the pressing last 4, so as to facilitate the holding and lifting of the pressing last 4, and effectively prevent the pressing last 4 from accidentally slipping and falling when being taken.

[0029] The outer contour of the bottom clamp seat 3 is matched with the outer contour of the sole of the finished shoe 6 .

[0030] The bottom surface of the bottom clamp seat 3 is flat to facilitate the installation of the bottom clamp seat 3, and the depth of the fitting groove 31 is 2-4 mm. Therefore, while ensuring that the sole of the finished shoe 6 can be stably placed in the fitting groove 31, the area of ​​the outer peripheral surface of the sole of the finished shoe 6 can be exposed to the maximum extent.

[0031] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
