[0028] In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more than two. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0029] In one embodiment of the present invention, Figure 1-4 As shown, a positioning device for a shoe material marking machine is provided, comprising a workbench 10, a lifting mechanism 20 and a transmission mechanism 30. The lifting mechanism 20 is disposed on the workbench 10, and a lifting seat 21 is disposed on the lifting mechanism 20. The lifting mechanism 20 is used to drive the lifting seat 21 to move upward or downward. The transmission mechanism 30 is disposed in the lifting seat 21. Two groups of positioning components 40 are disposed on the transmission mechanism 30. The transmission mechanism 30 is used to drive the two groups of positioning components 40 to move relatively inward or relatively outward.

[0030] The positioning assembly 40 includes a positioning drive member 41 and a material pressing member 42. The positioning drive member 41 is slidably connected to the transmission mechanism 30, and is used to drive the material pressing member 42 to approach or move away from the shoe material. The material pressing member 42 is arranged at the output end of the positioning drive member 41, and is used to press the shoe material onto the workbench 10.

[0031] In this embodiment, the positioning drive member 41 is a motor. When drawing lines, the lifting seat 21 is moved close to the shoe material through the lifting mechanism 20, and then the positioning drive member 41 drives the pressing member 42 to press the shoe material onto the workbench 10, so that the movement of the pressing member 42 is smoother, thereby improving the stability of the pressing member 42.

[0032] By setting the positioning component 40, when the shoe material is located at the marking station on the workbench 10, the lifting plate is driven close to the shoe material by the lifting mechanism 20, and the pressing component 42 of the positioning component 40 is driven further close to the shoe material by the positioning driving member 41 of the positioning component 40, and then the shoe material is pressed on the workbench 10 by the pressing components 42 at both ends of the lifting seat 21, thereby realizing the pressing and positioning of the shoe material, avoiding the phenomenon of the shoe material moving when marking. At the same time, the distance between the two groups of positioning components 40 is adjusted by the transmission mechanism 30 to adapt to the marking of different types of shoe materials, simplifying the adjustment steps and improving work efficiency.

[0033] Preferably, the material pressing component 42 includes a telescopic rod 421 and a pressing plate 422. The telescopic rod 421 is arranged on the output end of the positioning driving member 41. The pressing plate 422 is arranged at the bottom end of the telescopic rod 421. When pressing the material, under the action of the telescopic rod 421, the pressing plate 422 can stably press the shoe material on the workbench 10 to prevent the shoe material from moving out of position.

[0034] Specifically, the telescopic rod 421 includes a connecting portion 421a, a fixing portion 421b and a spring 421c. One end of the connecting portion 421a is connected to the output end of the positioning drive member 41, and the other end is slidably connected to the fixing portion 421b. The end of the fixing portion 421b is connected to the pressing plate 422. The spring 421c is sleeved on the outside of the connecting portion 421a and is located between the connecting portion 421a and the fixing portion 421b. When pressing the material, the connecting portion 421a gradually slides into the fixing portion 421b, and under the action of the spring 421c, the impact force between the pressing plate 422 and the workbench 10 is buffered, so that the pressing plate 422 is more stable during the descent process, and the phenomenon of shoe material displacement is avoided.

[0035] Specifically, the material pressing component 42 further includes a connecting sleeve 423 and two groups of pressing blocks 424. The connecting sleeve 423 is arranged between the positioning driving member 41 and the telescopic rod 421. The two groups of pressing blocks 424 are respectively arranged at both ends of the pressing plate 422. One end of the pressing block 424 is rotatably connected to one end of the pressing plate 422, and the other end is rotatably connected to the connecting sleeve 423 through a connecting rod. The pressing plate 422 and the pressing block 424 are provided with slots. The pressing block 424 is rotatably connected in the slot, and the outer wall of the pressing block 424 coincides with the inner wall of the slot. When the pressing plate 422 presses the shoe material, the positioning drive member 41 continues to extend outward, and the connecting sleeve 423 moves downward with the extension and retraction of the telescopic rod 421, driving the connecting rod to press the pressing blocks 424 at both ends downward on the four sides of the shoe material, so that the entire shoe material is pressed by the pressing plate 422 and the four sides of the shoe material are pressed by the pressing blocks 424, thereby preventing the shoe material from moving out of place and the periphery of the shoe material from warping up, which affects the effect of drawing lines.

[0036] Preferably, the transmission mechanism 30 includes a transmission drive member 31 and a bidirectional threaded shaft. The transmission drive member 31 is disposed in the lifting seat 21. The bidirectional threaded shaft is rotatably connected in the lifting seat 21 and is coaxially arranged with the transmission drive member 31. The output end of the transmission drive member 31 is connected to the bidirectional threaded shaft. The bidirectional threaded shaft includes a first thread segment 321, a transition segment 322 and a second thread segment 323. The first thread segment 321 is connected to the output end of the transmission drive member 31, the transition segment 322 is connected to the first thread segment 321, and the second thread segment 323 is connected to the transition segment 322. The two sets of positioning components 40 are threadedly connected to the first thread segment 321 and the second thread segment 323, respectively. The threads of the first thread segment 321 and the second thread segment 323 are arranged oppositely. In this embodiment, the transmission driving member 31 is a motor. When the transmission driving member 31 is started, the transmission driving member 31 drives the bidirectional threaded shaft to rotate, and drives the two groups of positioning components 40 to move relatively inward or relatively outward through the first thread segment 321 and the second thread segment 323, thereby adjusting the distance between the two groups of positioning components 40 to adapt to the drawing of different types of uppers and soles, simplifying the adjustment steps, and improving the practicality of the positioning device.

[0037] Preferably, the lifting mechanism 20 includes two groups of support frames 22. The two groups of support frames 22 are arranged on the workbench 10 in a relative manner. The lifting seat 21 is located between the two groups of support frames 22. A longitudinal moving module 23 is provided on the support frame 22, and the longitudinal moving module 23 is connected to the lifting seat 21. In this embodiment, the longitudinal moving module 23 is a vertically arranged linear moving module, and the lifting seat 21 is driven to move up and down by the longitudinal moving module 23, so that the positioning assembly 40 is close to the shoe material, which is convenient for adjusting the spatial position of the lifting seat 21.
