DETAILED DESCRIPTION

[0024] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] The safety shoe sole punching device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0026] The safety shoe sole punching equipment provided in the embodiment of the present application can be used in the production and processing process of safety shoes for punching the soles of safety shoes. It can push and transport the sole material while punching the sole, so as to effectively reduce the equipment cost and energy consumption, and can also automatically separate the punched sole from the sole material, so as to improve the production efficiency of sole punching.

[0027] like Figure 1-Figure 5 As shown, the safety shoe sole punching equipment of the embodiment of the present application may include a punching stand 1, a mounting frame 2, a first conveying mechanism 3, a punching propulsion mechanism 4, a clamping mechanism 5, a pushing mechanism 6, a second conveying mechanism 7 and a driving mechanism 8.

[0028] The first conveying mechanism 3 is arranged on the punching platform 1, and the first conveying mechanism 3 is used to carry the sole material to be punched. The mounting frame 2 is fixedly arranged on the punching platform 1. The punching propulsion mechanism 4 is rotatably arranged on the punching platform 1, and the punching propulsion mechanism 4 is located above the first conveying mechanism 3. The punching propulsion mechanism 4 is used to punch the sole material to be punched and propel it. The clamping mechanism 5 is arranged on the punching propulsion mechanism 4, and the clamping mechanism 5 is used to clamp the punched safety shoe sole. The second conveying mechanism 7 is arranged on the mounting frame 2, and the second One end of the conveying mechanism 7 is located in the punching advancement mechanism 4, and the second conveying mechanism 7 is used to convey the punched safety shoe soles. The pushing mechanism 6 is rotatably arranged on the mounting frame 2, and the pushing mechanism 6 is used to push the safety shoe soles clamped by the clamping mechanism 5 to the second conveying mechanism 7. The driving mechanism 8 is arranged on the mounting frame 2, and the driving mechanism 8 is respectively connected to the punching advancement mechanism 4, the pushing mechanism 6 and the second conveying mechanism 7, wherein the driving mechanism 8 is used to drive the punching advancement mechanism 4 and the pushing mechanism 6 to rotate in opposite directions, and drive the second conveying mechanism 7 to perform conveying operations.

[0029] Specifically, during the production and processing of safety shoes, when the soles of the safety shoes need to be punched, the relevant personnel first place the sole material on the first conveying mechanism 3, and then the relevant personnel start the driving mechanism 8 to drive the punching propulsion mechanism 4 to rotate. When the punching propulsion mechanism 4 contacts the sole material during the rotation process, the punching propulsion mechanism 4 punches the sole material to obtain the safety shoe sole, and then the clamping mechanism 5 clamps and fixes the punched safety shoe sole so that the punched safety shoe sole rotates with the punching propulsion mechanism 4.
