Description

Technical Field

[0001] This utility model relates to the field of shoe manufacturing technology, and in particular to a laser drilling device for shoe soles. Background Technology

[0002] Thousand-layered cloth shoes are comfortable, lightweight, slip-resistant, and breathable, and have long been loved by consumers. The production of thousand-layered cloth shoes is complex, difficult, and time-consuming, with very strict requirements. Each pair of shoes involves dozens of steps, including cutting the sole pattern, filling the thousand-layered sole, stitching the sole, cutting the upper, and shaping the shoe last. Among these, stitching the sole is a crucial step, as its quality directly affects the flatness and comfort of the sole. The manual stitching is very labor-intensive, requiring the use of an awl and hemp thread with needles to stitch each shoe stitch by stitch, demanding at least 81 stitches per square inch, and at least 2000 stitches per pair.

[0003] In the existing technology, when laser drilling is performed on shoe soles, the conventional working steps are to place the shoe sole in the station below the laser, limit the shoe sole, and then use the laser to drill holes. After the drilling is completed, the shoe sole is removed. This results in the feeding, drilling, and unloading all being done in one station, and repeated manual feeding and unloading leads to low equipment efficiency. Utility Model Content

[0020] Example 1

[0021] like Figures 1-3 As shown in the figure, the laser drilling device for shoe soles proposed in this embodiment includes a support plate 1, a turntable 2, a transparent cover 3, a material stacking shell 4, and a gas filtration device.

[0022] The support plate 1 has a material discharge hole 101; the bottom of the support plate 1 is provided with a bracket 10; the turntable 2 has multiple limiting holes 201 arranged in a ring array along its upper edge, with at least three limiting holes 201 provided. This arrangement ensures that the device has at least independent material feeding, drilling, and unloading stations. The turntable 2 is rotatably mounted on the support plate 1, and the support plate 1 is equipped with a servo motor 20 for driving the turntable 2 to rotate; the material stacking shell 4 is located above the turntable 2 and is connected to the support plate 1.

[0023] A transparent cover 3 is positioned above the turntable 2 and is connected to the support plate 1. A laser drilling mechanism is installed inside the transparent cover 3. This mechanism includes a first electric push rod 11, a second electric push rod 13, a laser drill 15, a first slide rail 16, a rectangular frame 17, a sliding seat 18, and a mounting rod 19. The first slide rail 16 and the rectangular frame 17 are both slidably installed inside the transparent cover 3. The length direction of the first slide rail 16 is perpendicular to the length direction of the rectangular frame 17. Both the first electric push rod 11 and the second electric push rod 13 are mounted on the transparent cover 3, and the output shaft of the first electric push rod 11 and... The output shaft of the second electric push rod 13 is connected to the first slide rail 16 and the rectangular frame 17 respectively. The sliding seat 18 is slidably mounted on the first slide rail 16. The laser drill 15 is connected to the sliding seat 18 through the mounting rod 19, which is located in the sliding hole of the rectangular frame 17. The first electric push rod 11 can drive the first slide rail 16 to move longitudinally, and the rectangular frame 17 drives the laser drill 15 to move longitudinally. The second electric push rod 13 drives the rectangular frame 17 to move laterally, and the rectangular frame 17 drives the laser drill 15 to move laterally, thereby realizing the horizontal movement of the laser drill 15.

[0024] A gas filtration device is installed on the transparent cover 3. The gas filtration device includes a fan 12 and a gas filter 14. The fan 12 is installed on the transparent cover 3. An air inlet pipe 122 is connected between the input end of the fan 12 and the inside of the transparent cover 3. An air outlet pipe 121 is connected to the output end of the fan 12. The gas filter 14 is installed on the air outlet pipe 121.

[0025] A conveyor belt device 9 is installed below the material discharge hole 101. The conveyor belt device 9 can transport the unloaded shoe soles to the next work station.

[0026] Specifically, multiple shoe soles that need to be perforated are stacked inside the stacking shell 4. The inner cavity of the stacking shell 4 is just big enough to accommodate the shoe soles. The turntable 2 is driven to rotate intermittently by the servo motor 20. The single rotation angle of the turntable 2 is 360 degrees / N, where N is the number of limit holes 201. It should be added that a PLC controller is installed on the periphery of the support plate 1 to control multiple devices.

[0027] When the limiting hole 201 on the turntable 2 rotates to the position directly below the stacking shell 4, the bottom of the shoe sole inside the stacking shell 4 falls into the corresponding limiting hole 201. The limiting hole 201 can only accommodate a single shoe sole. As the turntable 2 continues to move, the shoe sole moves to the inside of the transparent cover 3 and is perforated by the laser perforation mechanism.

[0028] After the punching process is completed, the turntable 2 is continuously driven to rotate. When the sole moves to the position directly above the material drop hole 101, the sole falls down through the material drop hole 101, realizing the function of automatic unloading.

[0029] Example 2

[0030] like Figure 1 As shown in the figure, the laser drilling device for shoe soles proposed in this embodiment, compared with the first embodiment, has a pressure plate 8 provided on the inner side of the stacking shell 4. Both ends of the pressure plate 8 are connected to limit blocks 81. Both ends of the stacking shell 4 are provided with vertical holes 401 for sliding of the two limit blocks 81 respectively. After multiple shoe soles are stacked, the pressure plate 8 is pressed on the top shoe sole, and the limit blocks 81 are placed inside the vertical holes 401. The pressure plate 8 can flatten the stacked shoe soles and avoid the phenomenon of local bulging of the shoe sole.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
