[0032] A shoe upper cutting machine according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0033] Reference Figure 1 A shoe upper cutting machine according to an embodiment of the utility model comprises a reeling mechanism 290, a cutting mechanism, an ejecting mechanism and a reeling mechanism 300 which are sequentially arranged along the conveying direction of the shoe upper material. The reeling mechanism 290 is used for delivering the shoe upper material. The cutting mechanism comprises a workbench 100, a die 110 located above the workbench 100, and a power component driving the die 110 to cut. The top of the workbench 100 supports the shoe upper material. The die 110 and the workbench 100 cooperate to cut the shoe upper material. The ejecting mechanism comprises an ejecting rod 120 and a first cylinder 130 driving the ejecting rod 120 to eject. The ejecting rod 120 can eject the shoe upper downward. The reeling mechanism 300 is used for collecting the shoe upper edge material.

[0034] In some embodiments of the present invention, referring to Figure 2 The workbench 100 is provided with two limit bars 170, and the two limit bars 170 are arranged opposite to each other. A limit channel 180 is formed between the two limit bars 170, and the limit channel 180 accommodates the passage of the upper material. Therefore, the limit channel 180 can limit the position of the upper material entering the cutting area to avoid the upper material from being conveyed out of position.

[0035] In some embodiments of the present invention, a limiting edge 190 is provided on one side of the limiting strip 170 close to the limiting channel, and the limiting edge 190 abuts against the top of the upper material, thereby preventing the upper material from escaping from the limiting channel.

[0036] In some embodiments of the utility model, a pressure rod 200 is arranged above the workbench 100. The pressure rod 200 is arranged in the discharge direction of the die 110. The upper material is allowed to pass between the pressure rod 200 and the workbench 100. Therefore, the pressure rod 200 can guide the cut upper material so that the ejection rod 120 can better eject the upper.

[0037] In some embodiments of the present invention, the power assembly includes a servo motor 210 , and the servo motor 210 drives the die 110 to cut the upper material up and down through a crank slider mechanism 220 .

[0038] Specifically, the crank slider mechanism 220 includes a crankshaft, a connecting rod hinged to the crankshaft, and a slider hinged to the connecting rod. By utilizing the high precision of the servo motor 210, the servo motor 210 drives the crankshaft to rotate, so that the connecting rod drives the slider to move up and down, thereby allowing the die 110 to accurately cut the upper material.

[0039] In some embodiments of the present invention, referring to Figure 3 The sliding end of the crank slider mechanism 220 is provided with a mounting plate 230, the mounting plate 230 has a T-shaped slot 240, the die 110 has a T-shaped portion 250, the T-shaped slot 240 accommodates the T-shaped portion 250, and the mounting plate 230 and the T-shaped portion 250 are connected by bolts.

[0040] Therefore, the T-slot 240 and the T-shaped portion 250 are used to cooperate and connect, so as to facilitate the installation and disassembly of the pressing mold 110 and the mounting plate 230, thereby facilitating the configuration of pressing molds 110 of different specifications to adapt to the pressing of shoe uppers of different specifications.

[0041] In some embodiments of the present invention, referring to Figure 4 and Figure 5 The die 110 has an annular blade 260, a spring 270 is arranged inside the annular blade 260, and an abutment portion 280 is arranged at the end of the spring 270. The abutment portion 280 is used to abut against the upper. Therefore, after the upper is cut out of the upper material, the abutment portion 280 of the spring 270 resets the upper to prevent the upper from being embedded in the annular blade 260, so that the upper moves synchronously with the waste material.

[0042] In some embodiments of the utility model, the ejection mechanism also includes a horizontally extending roller 140 and a protrusion 150 arranged on the radial outer surface of the roller 140. The ejection rod 120 and the roller 140 are arranged in sequence along the conveying direction of the upper material. The roller 140 rolls horizontally so that the protrusion 150 ejects the upper.

[0043] Therefore, after the individual shoe uppers that have not been ejected by the ejection rod 120 are rolled by the roller 140, the protrusion 150 can also eject the shoe uppers, ensuring that each shoe upper can be ejected.

[0044] In some embodiments of the present invention, the raised portion 150 is in a semi-spherical shape, thereby preventing the raised portion 150 from being hooked with the edge material of the upper.

[0045] In some embodiments of the present invention, a collection box 160 is disposed below the ejection rod 120 and the roller 140 , and the collection box 160 is used to collect the uppers, thereby facilitating the collection of the uppers.

[0046] Therefore, this embodiment has the following effects:

[0047] 1. The utility model is provided with an unwinding mechanism 290, a cutting mechanism, an ejecting mechanism and a rewinding mechanism 300. The unwinding mechanism 290 unwinds the rolled upper material, and the unwinding mechanism 290 conveys the upper material to the cutting area of ​​the workbench 100. The cutting mechanism is used to cut the upper material into the upper of the required shape, and the ejecting mechanism separates the upper from the cut upper material. Finally, the rewinding mechanism 300 is used to rewind and recycle the upper edge material, thereby improving the degree of automation of the equipment.

[0048] 2. The utility model sets a workbench 100, a die 110 and a power component. After the unwinding mechanism 290 conveys the upper material to the workbench 100, the power component is used to drive the die 110 to move up and down. The die 110 is pressed down to cut the upper material out of the shoe upper, avoiding the traditional step of manually placing the knife die on the upper material, reducing manual labor intensity, and improving cutting efficiency.

[0049] 3. The utility model provides an ejector rod 120 and a first cylinder 130, and utilizes the first cylinder 130 to drive the ejector rod 120 to descend. The ejector rod 120 can eject the shoe upper from the cut shoe upper material, eliminating the traditional manual process of removing the shoe upper from the die, thereby reducing labor costs and greatly improving cutting efficiency.
