The support plate can prevent the upper end of the lower transmission belt 3 from falling during the pressing process.

[0024] A plurality of automatic pressing mechanisms are arranged in an array along the path direction of the lower transmission belt 3, and the automatic pressing mechanism includes a mounting plate 4, a pressing plate a151, a pressing plate b152, a pressing plate c153, a pressing plate d154, a transmission assembly, a push rod 12, and an elastic reset assembly. A support rod 18 is connected between the mounting plate 4 and the lower transmission belt 3. The pressing plates a151, b152, c153, and d154 are all slidably mounted around the mounting plate 4. The push rod 12 is mounted by the elastic reset assembly. On the mounting plate 4, the elastic reset assembly includes a guide rod b24, a spring b25, a connecting slider b26 and two mounting blocks 23. The two mounting blocks 23 are arranged side by side on the mounting plate 4. The guide rod b24 is connected between the two mounting blocks 23. The connecting slider b26 is slidably arranged on the guide rod b24 and connected to the push rod 12. The spring b25 is sleeved and installed on the guide rod b24. The transmission assembly is used to convert the movement of the push rod 12 into the pressing plates a151, b152 and c153. The transmission assembly includes a rack a191, a rack b192, a rack c193, a rack d194, a gear a211, a gear b212, a mounting shaft 22, and four connecting sliders a20. The four connecting sliders a20 are respectively connected to the pressing plate a151, the pressing plate b152, the pressing plate c153, and the pressing plate d154. The mounting plate 4 is provided with four sliding holes 401. The four connecting sliders a20 are respectively slidably arranged on the inner sides of the four sliding holes 401. , rack a191, rack b192, rack c193 and rack d194 are respectively connected to the four connecting sliders a20, rack a191 is connected to the connecting slider b26, gear a211 and gear b212 are both rotatably mounted on the mounting plate 4 through the mounting shaft 22, rack a191 and rack b192 are both meshed with gear a211, rack c193 and rack d194 are both meshed with gear b212; the guide plate b14 is installed on the side of the frame 1 and one end of it is a structure bent outward.

[0025] A plurality of automatic pressing mechanisms are arranged in an array along the path direction of the upper transmission belt 2, and the automatic pressing mechanisms include a fixed block 16, a guide rod a171, a spring a172, a pressure block 173 and a hemispherical block 174. The fixed block 16 is fixed on the upper transmission belt 2, and the guide rod a171 movably passes through the fixed block 16 and the upper transmission belt 2.

[0026] In this embodiment, the upper with the shoe last is bonded to the sole and placed on the mounting plate 4, so that the shoe is placed between the pressing plates a151, b152, c153 and d154, and the upper transmission belt 2 and the lower transmission belt 3 are driven to rotate by the provided driving mechanism, thereby driving the shoe to move. When the push rod 12 begins to contact the inclined surface of the guide plate b14, the push rod 12 is forced to move inward, and the pressing plates a151, b152, c153 and d154 are driven inward at the same time with the cooperation of the transmission assembly, so that the peripheral side of the sole is pressed against the peripheral side of the upper. When the hemispherical block 174 begins to contact the inclined surface of the guide plate a13, the push rod 12 is forced to move inward. The pressing block 173 starts to move downward and is pressed against the shoe last. The shoe last applies pressure to press the bottom end of the upper against the sole, so that the upper and the sole are better bonded together. When the hemispherical block 174 is separated from the guide plate a13, the pressing block 173 is automatically reset under the elastic force of the spring a172. When the push rod 12 is separated from the guide plate b14, the pressing plates a151, b152, c153 and d154 are driven to reset under the elastic force of the spring b25. When the shoes start to rotate downward, they fall from the mounting plate 4 under the action of gravity, realizing the function of automatic unloading. A collection box is set below the lower transmission belt 3 for collecting shoes.
