[0030] A shoe upper polishing device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 and Figure 2 The present invention provides a shoe upper 130 grinding device, including a feeding mechanism, a clamping mechanism, a grinding mechanism and a chip sweeping mechanism. The feeding mechanism includes a slider 100 and a first cylinder 110 for driving the slider 100 to move. The slider 100 is provided with a material plate 120, and the material plate 120 is provided with an inverted shoe upper 130. The clamping mechanism includes a clamping assembly and a power member 140 for driving the clamping assembly to clamp. The clamping assembly includes a left pressure plate 150 and a right pressure plate 160. The left pressure plate 150 and the right pressure plate 160 can clamp the inverted shoe upper 130. ; A grinding mechanism, including a robotic arm 170 and a grinding head 180 arranged at the free end of the robotic arm 170, the robotic arm 170 is arranged in the moving direction of the slider 100, and the robotic arm 170 can drive the grinding head 180 to grind the shoe upper 130; a chip sweeping mechanism, including a first brush 190 for abutting against the top of the inverted shoe upper 130, and a second brush 200 for abutting against the side of the inverted shoe upper 130, the first brush 190 and the second brush 200 are arranged in the moving direction of the slider 100 and are located on the side of the clamping assembly away from the robotic arm 170.

[0032] It should be noted that the power member 140 may be a cylinder, and the left pressure plate 150 and the right pressure plate 160 are driven by the cylinders respectively.

[0033] In some embodiments of the utility model, two parallel distributed pins 210 are provided on the material plate 120, and the pins 210 are used to be plugged into the holes of the shoe last in the upper 130, so that the upper 130 is in an upright state and the upper 130 can also be prevented from rotating.

[0034] In some embodiments of the present invention, the first brush 190 and the second brush 200 are arranged sequentially in a direction away from the clamping assembly.

[0035] Therefore, when the material plate 120 passes through the first brush 190, the first brush 190 is used to sweep away the wear debris from the top of the inverted upper 130. Then, when the material plate 120 passes through the second brush 200, the second brush 200 is used to sweep away the wear debris from the side of the inverted upper 130. This sweeping order is conducive to reducing wear debris.

[0036] In some embodiments of the present invention, referring to Figure 3 The chip sweeping mechanism includes a first bracket, which includes a vertical rod 220 and a hanging rod 230 connected to the top of the vertical rod 220. A first brush 190 is arranged at the bottom of the hanging rod 230. Therefore, the hanging rod 230 makes the first brush 190 be at a high position, and the shoe upper 130 will not interfere with the hanging rod 230 when passing through the first brush 190.

[0037] In some embodiments of the present invention, referring to Figure 4 Two second brushes 200 are provided, and the two second brushes 200 are arranged opposite to each other, and a sweeping channel 240 is formed between the two second brushes 200. Therefore, the upper 130 can pass through the sweeping channel 240, and the second brushes 200 can sweep the side of the upper 130 to the maximum extent, greatly reducing the wear debris on the surface of the upper 130.

[0038] In some embodiments of the present invention, a collecting groove 250 is further included. The slider 100 is slidably disposed in the collecting groove 250. The collecting groove 250 is used to collect wear debris.

[0039] Therefore, the wear debris generated by the first brush 190 and the second brush 200 when cleaning the shoe upper 130 can fall into the collecting groove 250 , and the collecting groove 250 is convenient for collecting the wear debris.

[0040] In some embodiments of the present invention, a guide rod 260 is provided on the side wall of the collecting tank 250 , and the guide rod 260 extends in a horizontal direction. The slider 100 is provided with a through hole, and the through hole accommodates the guide rod 260 .

[0041] Therefore, the slider 100 does not need to contact the collecting groove 250 , thereby avoiding frictional contact between the slider 100 and the wear debris in the collecting groove 250 during the sliding process.

[0042] In some embodiments of the present invention, the left pressure plate 150 and the right pressure plate 160 are respectively provided with a silicone pad 270, and the silicone pad 270 is used to abut against the side of the upper 130, thereby preventing the left pressure plate 150 and the right pressure plate 160 from crushing the upper 130.

[0043] Therefore, this embodiment has the following effects:

[0044] 1. The utility model provides a slider 100 and a first cylinder 110, so that an operator can place the shoe upper 130 upside down on the material plate 120, and use the first cylinder 110 to drive the slider 100 to move, and the material plate 120 moves with the slider 100, so that the shoe upper 130 is transported to the polishing position, thereby replacing manual loading and improving the degree of automation of the equipment.

[0045] 2. The utility model sets a left pressure plate 150 and a right pressure plate 160. After the material plate 120 reaches the grinding position, the power member 140 is used to drive the clamping assembly to clamp. The left pressure plate 150 and the right pressure plate 160 can clamp the side of the shoe upper 130 in the horizontal direction. There is no need to manually hold the shoe upper 130 for grinding, which reduces the labor intensity of the operator.

[0046] 3. The utility model provides a mechanical arm 170 and a grinding head 180, and utilizes the mechanical arm 170 to drive the grinding head 180 to move, so that the grinding head 180 grinds the shoe upper 130, and there is no need for manual handheld grinding, thereby improving the uniformity of grinding.

[0047] 4. The utility model is provided with a first brush 190 and a second brush 200. Therefore, after the shoe upper 130 is polished, the first cylinder 110 drives the slider 100 to reset, and the shoe upper 130 on the material plate 120 passes through the first brush 190 and the second brush 200. The first brush 190 can sweep the top of the inverted shoe upper 130, and the second brush 200 can sweep the side of the inverted shoe upper 130, thereby reducing the wear debris on the surface of the shoe upper 130 and reducing the difficulty of cleaning the shoe upper 130.
