[0026] Example 1
[0027] A shoe sole trimming device, such as Figures 1 to 3As shown, the device includes a workbench 1, a fixed frame 5 fixed to the top of the workbench 1, a connecting frame 2 rotatably connected to the inner wall of the top of the fixed frame 5, a motor 17 with an output shaft connected to the connecting frame 2 installed inside the workbench 1, multiple load-bearing components 3 connected to the side wall of the connecting frame 2, a plane 6 provided on the inner wall of the fixed frame 5, the plane 6 being composed of a guide surface 1 and a guide surface 2 18, the guide surface 2 18 being a V-shaped surface with its top end higher than the guide surface 1 in the plane 6, multiple connecting blocks 7 aligned with the load-bearing components 3 connected to the side wall of the connecting frame 2, a moving rod 8 slidably fitted on the inner wall of the connecting block 7, and a top of the moving rod 8 being provided with a connection to the plane 6. 6. Rolling friction ball bearings; the top side wall of the moving rod 8 is provided with an annular protrusion; the outer wall of the moving rod 8 is fitted with a spring 9; the two ends of the spring 9 are respectively in contact with the annular protrusion and the connecting block 7; the top of the worktable 1 is provided with a trimming assembly 4; the trimming assembly 4 is located on one side of a bearing assembly 3; the trimming assembly 4 has the same structure as the trimming mechanism in the patent with Chinese patent announcement number CN213470627U; the bearing assembly 3 includes a rotating rod 10 and a spline 11; the rotating rod 10 is rotatably fitted to the connecting frame 2; the spline 11 is fixed to the bottom end of the rotating rod 10; the rotating rod 10 and the moving rod 8 are aligned.
[0028] The trimming assembly 4 has air intake hoods 15 on both sides with openings facing the contact surface between the trimming assembly 4 and the sole. The workbench 1 has a collection chamber communicating with the air intake hoods 15. A fan 16 is provided on one side of the collection chamber. A filter plate is provided between the fan 16 and the collection chamber. A motor 14 is installed inside the workbench 1. The motor 14 is located on one side of the trimming assembly 4. The output shaft of the motor 14 is fixed to a mounting bracket. A telescopic rod 13 is installed on the inner wall of the mounting bracket. The telescopic end of the telescopic rod 13 is connected to a groove 12. The groove 12 and the spline 11 are slidably limited.
[0029] During operation, the worker places the shoe sole between the moving rod 8 and the rotating rod 10 below the guide surface 18. The motor 17 drives the connecting frame 2 to rotate. Because the guide surface 18 is a V-shaped surface with its top higher than the guide surface 1 in plane 6, the guide surface 18 gradually presses the moving rod 8 downwards, causing the spring 9 to compress and deform until the top of the ball bearing on the spring 9 is at the same height as the guide surface in plane 6. At this point, the moving rod 8 and the rotating rod 10 cooperate to clamp the shoe sole. Then, the connecting frame 2 continues to rotate, moving the clamped shoe sole to one side of the trimming assembly 4 for grinding and trimming. When the telescopic rod 13 pushes the flower groove 12 upward, the flower groove 12 is connected to the spline 11, the motor 14 drives the rotating rod 10 to rotate, causing the sole to rotate. During the trimming process, the fan 16 creates a negative pressure in the collection chamber, and the debris generated during trimming is sucked into the collection chamber through the suction hood 15. After the trimming is completed, the motor 2 drives the connecting frame 2 to rotate, moving the sole to be polished to one side of the trimming assembly 4 for polishing. When the polished sole moves to below the guide surface 2 18, the spring 9 pushes the moving rod 8 upward, and the moving rod 8 and the rotating rod 10 no longer clamp the sole.
[0030] By setting up a connecting frame 2, a plane 6, a connecting block 7, a moving rod 8, and a spring 9, the rotation of the connecting frame 2 is used to achieve automatic clamping and release of the shoe sole. At the same time, the shoe sole that has been trimmed can be replaced during the trimming process, thereby improving production efficiency.
[0031] By incorporating an air intake hood 15 and a fan 16, debris generated during trimming can be collected, preventing it from scattering and polluting the environment.
[0032] Example 2
[0033] A shoe sole trimming device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 4 As shown, the top of the workbench 1 is provided with an air knife 19 and an air suction pipe 20. The air knife 19 and the air suction pipe 20 are located on both sides of a support component 3, and the openings of the air knife 19 and the air suction pipe 20 face the support component 3. The air knife 19 is connected to the air outlet of the fan 16, and the air suction pipe 20 is connected to the collection chamber. Another motor 14 is provided on one side of the air knife 19 and the air suction pipe 20.
[0034] When the trimmed sole is moved to the side of the air knife 19 and the suction pipe 20, the airflow drawn by the fan 16 is sprayed at high speed from the air knife 19 to the sole. The airflow cleans the surface of the sole, removes the debris attached to the sole surface, and collects the cleaned debris through the suction pipe 20.
[0035] By setting up the air knife 19 and the air suction pipe 20, the surface of the shoe sole after trimming is cleaned to remove the debris attached to the surface of the shoe sole and ensure that the shoe sole is clean.
[0036] Working principle: During operation, the worker places the shoe sole between the moving rod 8 and the rotating rod 10 below the guide surface 18. The motor 17 drives the connecting frame 2 to rotate. Since the guide surface 18 is a V-shaped surface with its top higher than the guide surface 1 in plane 6, the guide surface 18 will gradually squeeze the moving rod 8 downwards, and the spring 9 will be compressed and deformed until the top of the ball bearing on the spring 9 is at the same height as the guide surface in plane 6. At this time, the moving rod 8 and the rotating rod 10 cooperate to clamp the shoe sole. Then the connecting frame 2 continues to rotate, moving the clamped shoe sole to the side of the trimming assembly 4 for grinding and trimming. At the same time, the telescopic rod 13 pushes the flower groove 12 upwards, and the flower groove 12 connects with the spline 11. The motor 14 drives the rotating rod 10 to rotate, causing... During the shoe sole rotation and trimming process, the blower 16 creates negative pressure in the collection chamber, drawing debris generated during trimming into the collection chamber through the suction hood 15. After trimming, the motor 2 drives the connecting frame 2 to rotate, moving the shoe sole to be polished to one side of the trimming assembly 4 for polishing. When the polished shoe sole moves below the guide surface 2 18, the spring 9 pushes the moving rod 8 upward, and the moving rod 8 and the rotating rod 10 no longer clamp the shoe sole. When the trimmed shoe sole moves to the side of the air knife 19 and the suction pipe 20, the airflow drawn by the blower 16 is sprayed at high speed from the air knife 19 to the shoe sole. The airflow cleans the surface of the shoe sole, removing the debris attached to the surface, and collects the cleaned debris through the suction pipe 20.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
