[0039] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0040] See Figures 1 to 4 The present invention provides an embossing device for shoe uppers, including a body 1, a frame 2 on the body 1, an embossing component 3 on the frame 2, the embossing component 3 being driven by a hydraulic cylinder 4, a movable seat 5 slidably connected to the body 1, a base 7 on the movable seat 5, a detachable positioning plate 8 installed on the base 7, and the positioning plate 8 being connected to the embossing component 3 via an air pump 9.

[0041] The embossing component 3 includes an embossing mold body 31. Elongated release nozzles 32 are symmetrically arranged on the front and rear sides of the embossing mold body 31. Both ends of the two release nozzles 32 are connected by connecting pipes 33. The release nozzles 32 are provided with nozzles 321 facing the embossing mold body 31. A heater is provided in the embossing mold body 31 to heat the embossing mold body 31.

[0042] A negative pressure chamber 71 is provided on the base 7;

[0043] The positioning plate 8 is provided with a positioning groove 81 that matches the shoe upper, and the bottom of the positioning groove 81 has multiple negative pressure holes 82 that communicate with the negative pressure chamber 71.

[0044] The air pump 9 is equipped with two air inlets and one air outlet. One air inlet is connected to the negative pressure chamber 71, and the air outlet is connected to the nozzle 321 of the demolding nozzle 32.

[0045] Using the above structure, when embossing the shoe upper, after the shoe upper is placed in the positioning groove 81 of the positioning plate 8, the embossing mold 31 of the embossing component 3 is driven by the hydraulic cylinder 4 to emboss the shoe upper and return to its original position. At the same time, the air pump 9 is started, which creates a negative pressure in the negative pressure chamber 71 in the base 7. The shoe upper is then adsorbed into the positioning groove 81 through the negative pressure hole 82. Simultaneously, the nozzle 321 of the demolding nozzle 32 on the embossing mold 31 sprays air onto the shoe upper to blow it off the embossing mold 31, preventing the shoe upper from sticking to the embossing mold 31. This avoids the shoe upper from moving with the embossing mold 31, thus ensuring the embossing effect of the shoe upper.

[0046] In one embodiment, see Figure 3 and Figure 4 The demolding nozzle 32 is equipped with an air inlet pipe 34 communicating with the nozzle 321, and the base 7 is equipped with an air outlet pipe 72 communicating with the negative pressure chamber 71. The nozzle 321 of the demolding nozzle 32 is connected to the air outlet of the air pump 9 through the air inlet pipe 34, and the base 7 is connected to the air inlet of the air pump 9 through the air outlet pipe 72. In practical applications, the arrangement of the air outlet pipe 72 and the air inlet pipe 34 facilitates the connection between the negative pressure chamber 71 of the base 7 and the air inlet of the air pump 9, and the connection between the nozzle 321 of the demolding nozzle 32 and the air outlet of the air pump 9.

[0047] In one embodiment, see Figure 2 and Figure 3 The positioning plate 8 is slidably connected to the base 7. Along the sliding direction of the positioning plate 8, a positioning shell 73 is provided on one side of the base 7. A slot 74 is provided on the positioning shell 73, and a locking block 75 is provided in the slot 74. One end of the locking block 75 is located in the slot 74, and the other end is located on the side of the positioning plate 8. In practical applications, the locking block 75 and the slot 74 cooperate to easily lock the locking block 75 on the side of the base 7, thereby limiting the positioning plate 8 and preventing it from easily detaching from the base 7 after installation. Furthermore, the positioning plate 8 can be detachably installed on the base 7, making it easy to replace the corresponding positioning plate 8 according to the shoe upper model, so as to be suitable for different shoe upper embossing.

[0048] The positioning plate 8 is equipped with a slider 83, and a protruding limiting block 84 is provided at the end of the slider 83. The base 7 is provided with a sliding groove 76 and a limiting slot 77 corresponding to the positions of the slider 83 and the limiting block 84, respectively. The slider 83 and the limiting block 84 are respectively embedded in the sliding groove 76 and the limiting slot 77. In practical applications, the slider 83 can be restricted in the sliding groove 76 by the cooperation of the limiting slot 77 and the limiting block 84, so that the positioning plate 8 can be slidably connected to the base 7.

[0049] In one embodiment, see Figure 1The moving base 5 is driven by the linear motor 6. The moving base 5 is slidably connected with the machine body 1 through a slide rail (not marked in the figure). In actual application, the moving base 5 can be driven to move on the machine body 1 through the linear motor 6, so that after the vamp is placed on the positioning plate 8, the vamp can be driven to be below the embossing component 3, and after the embossing is completed, the vamp can be moved out, so as to facilitate the vamp to be taken out.

[0050] In the description of the present application, it should be explained that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0051] Those skilled in the art should understand that the above embodiments are only for clearly illustrating the present application, and are not intended to limit the scope of the present application. For those skilled in the art, other changes or modifications can be made on the basis of the above application, and these changes or modifications are still within the scope of the present application.
