[0023] See Figure 1 and Figure 2 The shown device is an automatic midsole edge trimming device, comprising a cabin 1 and a vacuum cleaner 2 installed on the side of the cabin 1, a negative pressure fan 21 being provided on the side of the vacuum cleaner 2, a suction pipe 22 being provided at the upper end of the vacuum cleaner 2, a cabin cover 3 being detachably installed at the front end of the cabin 1, a control panel 4 being integrated at the upper position of the cabin cover 3, a rotating unit, a clamping unit and an edge trimming unit being installed through the cabin 1, and the vacuum cleaner 2, the rotating unit, the clamping unit and the edge trimming unit are all controlled and driven by the control panel 4.

[0024] In the above technical solution, the midsole is clamped by the cooperation of the rotating unit and the clamping unit. After clamping, the midsole is in a rotating state, and the edge trimming work is completed by the edge trimming unit by changing its position along the outer periphery of the rotating unit. The operation efficiency is high and over-cutting is avoided.

[0025] See Figure 1 and Figure 2As shown, the rotating unit includes a rotating shaft 51, a reduction motor 52 and a lower clamping plate 53. A bearing 54 is provided between the rotating shaft 51 and the cabin 1. The reduction motor 52 is installed inside the cabin 1 and is connected to drive the rotating shaft 51. The lower clamping plate 53 is installed at the upper end of the rotating shaft 51 and cooperates with the chamfering unit. The lower clamping plate 53 cooperates with the clamping unit. The reduction motor 52 is connected to the control panel 4.

[0026] In the above technical solution, the torque is provided by the reduction motor 52 to drive the rotating shaft 51 to rotate, and the midsole is clamped by the cooperation between the lower clamping plate 53 and the clamping unit. After clamping, the midsole begins to rotate under the rotation of the rotating shaft 51, and the chamfering unit acts on the outer periphery of the lower clamping plate 53. As the lower clamping plate 53 rotates, the chamfering of the midsole is completed by the chamfering unit.

[0027] See Figure 1 As shown, the clamping unit includes a bracket 61, an electric push rod 62 and an upper clamping plate 63. The bracket 61 is fixed to the rear of the cabin 1, and the electric push rod 62 is installed through the bracket 61. The upper clamping plate 63 corresponds to the lower clamping plate 53. The upper end of the upper clamping plate 63 is provided with a first bearing 64. The movable end of the electric push rod 62 cooperates with the first bearing 64. The electric push rod 62 is connected to the control panel 4.

[0028] In the above technical solution, the position of the upper clamping plate 63 needs to be consistent with that of the lower clamping plate 53 in order to provide a higher clamping effect.

[0029] See Figure 2 As shown, protrusions 8 are provided on the opposite surfaces of the lower clamping plate 53 and the upper clamping plate 63 .

[0030] The purpose of providing the protrusions 8 is to increase friction and enhance the fixing effect on the midsole.

[0031] See Figure 1 and Figure 2As shown, the edge trimming unit includes a movable tube 71 and a motor 72. The motor 72 is fixed to the lower end of the movable tube 71. The output shaft of the motor 72 passes through the movable tube 71 upward and is equipped with a grinding wheel 73. The outer wall of the movable tube 71 is rotatably provided with a guide wheel 74 near the upper end. The guide wheel 74 fits the outer wall of the lower clamping plate 53. A sliding rod 75 is provided on the outer wall of the movable tube 71. A vertical frame 76 is provided on the inner wall of the cabin 1. The sliding rod 75 passes through the vertical frame 76 and is engaged with a limiting nut 77. A horizontal slide groove is provided on the top of the cabin 1. The movable tube 71 slides along the horizontal slide groove. A cover plate 78 is provided on the outer wall of the movable tube 71, and the cover plate 78 covers the horizontal slide groove. A bracket body 79 is installed on the upper end of the cover plate 78, and a wind nozzle 710 corresponding to the grinding wheel 73 is installed through the bracket body 79, and a folding wind duct 711 is cooperated between the wind nozzle 710 and the suction pipe 22; a spring 712 is provided on the sliding rod 75, and a position-adjustable limit sleeve 713 is provided on the sliding rod 75, and the limit sleeve 713 is locked by a screw, and the spring 712 acts between the vertical frame 76 and the limit sleeve 713. Under the action of the spring 712, the guide wheel 74 always fits the outer wall of the lower splint 53.

[0032] In the above technical solution, the rebound force is provided by the spring 712, so that the guide wheel 74 always fits the outer wall of the lower clamping plate 53. As the lower clamping plate 53 rotates, the guide wheel 74 rotates one circle along the outer wall of the lower clamping plate 53. At the same time, the grinding wheel 73 completes the trimming of the outer wall of the midsole. The operating efficiency of the entire work is high, and as long as the clamping position of the midsole is correct, the problem of over-cutting can be avoided.

[0033] See Figure 1 As shown, an arc-shaped guard plate 181 is provided on the top of the cabin 1 at the front and rear sides of the lower clamping plate 53 .

[0034] In the above technical solution, the provision of the guard plate 181 can block the splashed waste and play a role in safety protection.
