[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 As shown, this utility model provides a shoe sole pressing device, including a base box 1. A rotating placement mechanism 2 is provided on the top of the base box 1, a hot pressing mechanism 3 is provided on the rear side of the base box 1, and a discharge mechanism 4 is provided on the left side of the hot pressing mechanism 3. The rotating placement mechanism 2 includes a fixed circular frame 21, which is fixedly installed on the top of the base box 1. A servo motor 22 is fixedly installed at the center of the bottom of the inner wall of the fixed circular frame 21, and an encoder 23 is fixedly installed on the outer wall of the servo motor 22. The encoder 23 is a device for measuring rotation angle and speed. By being installed on the servo motor 22, it provides real-time feedback on the rotation information and position of the servo motor 22. In order for the control system to accurately adjust the output signal, the output shaft of the servo motor 22 is fixedly mounted with a turntable 24. Four mold base plates 25 are fixedly mounted in a ring array on the top of the turntable 24. The top of each of the four mold base plates 25 is provided with four positioning holes 26 in a rectangular array. Each of the four mold base plates 25 is provided with a shoe sole mold plate 27. Each of the four shoe sole mold plates 27 is provided with four vertically penetrating shoe sole positioning through holes 28. The bottom of each of the four shoe sole mold plates 27 is fixedly mounted with four positioning rods 29 in a rectangular array. The four positioning rods 29 at the bottom of the four shoe sole mold plates 27 are respectively engaged with the four positioning holes 26 at the top of the four mold base plates 25.

[0024] When it is necessary to press the sole and the upper together, simply glue the sole and the upper together beforehand, and place the sole into the four sole positioning through holes 28 opened in the sole mold plate 27 at the top of the mold base plate 25. Then, the encoder 23 can be used to precisely control the speed and rotation angle of the servo motor 22, so that it rotates at a preset 90-degree rotation angle, and one of the four sole mold plates 27 rotates to the pressing position and stops. At the same time, the sole mold plates 27 at the top of the four mold base plates 25 can be pulled up and removed directly. By preparing multiple sole mold plates 27 with sole positioning through holes 28 of different sizes in advance, the positioning rod 29 can be quickly aligned with the positioning hole 26 and inserted for installation, which facilitates the pressing of soles of different sizes.

[0025] like Figure 3 As shown, the hot pressing mechanism 3 includes an L-shaped support plate 31. The front end of the horizontal part of the L-shaped support plate 31 is fixedly connected to the rear side of the base box 1. An extension plate 32 is fixedly installed on the front side of the vertical part of the L-shaped support plate 31. A hydraulic cylinder 33 is fixedly installed on the top of the extension plate 32. The output end of the hydraulic cylinder 33 extends through to the bottom of the extension plate 32 and is fixedly installed on a pressing plate 34. A heating plate 35 is fixedly installed on the bottom of the pressing plate 34. The heating plate 35 is located directly above one of the four shoe sole mold plates 27. A heating power supply 36 and an air tank 38 are fixedly installed on the right side of the L-shaped support plate 31. The heating power supply 36 is located below the air tank 38. A wire is electrically connected to the front output end of the heating power supply 36. The other end of the wire is electrically connected to the right input end of the heating plate 35. Limiting slide rods 37 are fixedly installed on both the left and right sides of the top of the pressing plate 34. Both limiting slide rods 37 are slidably connected to the extension plate 32. The length of the limiting slide rods 37 is greater than the distance between the extension plate 32 and the shoe sole mold plate 27.

[0026] When the sole mold plate 27, containing the glued upper and sole, rotates and moves to below the heating plate 35, the hydraulic cylinder 33 at the top of the extension plate 32 is activated, causing the pressing plate 34 to descend. Before descending, the heating plate 35 is heated by the connection between the heating power supply 36 and the heating plate 35. When the pressing plate 34 is pressed down, it works with the heated plate 35 to press the sole and upper in the sole positioning through hole 28 of the sole mold plate 27, ensuring a firm bond. When the pressing plate 34 descends and rises, the sliding of the limiting slide rod 37 and the extension plate 32 maintains stability. After pressing is completed, the sole mold plate 27 can continue to rotate, allowing the next sole mold plate 27 containing the sole and upper to rotate 90 degrees and move to below the heating plate 35. This process is repeated to perform rapid pressing.

[0027] like Figure 4 , Figure 5As shown, the discharge mechanism 4 includes a fixed side plate 41, which is fixedly installed on the left side of the L-shaped support plate 31. A connecting plate 42 is fixedly installed at the front end of the fixed side plate 41, and a pneumatic linear slide rail 43 is fixedly installed at the front end of the connecting plate 42. The pneumatic linear slide rail 43 adopts TOLOMATIC The LS model pneumatic slide rail, pneumatic linear slide rail 43 includes a slide rail, a slider 44 is slidably mounted on the outer wall of the slide rail, an mounting plate 45 is fixedly mounted on the front end of the slider 44, a cylinder 46 is fixedly mounted on the front end of the mounting plate 45, a suction cup mechanism 47 is provided at the bottom output end of the cylinder 46, the suction cup mechanism 47 includes a hanging plate 471, the hanging plate 471 is fixedly mounted at the bottom of the output end of the cylinder 46, four suction cup mounting plates 472 are evenly fixedly mounted on the bottom of the hanging plate 471, the four suction cup mounting plates 472 are respectively located above the four shoe sole positioning through holes 28 opened on the left side of the top of the turntable 24 shoe sole mold plate 27, vacuum suction cups 473 are fixedly mounted on the left and right sides of the bottom of the four suction cup mounting plates 472, and an air extraction pipe 474 is fixedly connected through the inner cavity of the several vacuum suction cups 473, and the other end of the air extraction pipe 474 is connected to a vacuum pump;

[0028] After being pressed, the sole mold plate 27, rotated 90 degrees, will move directly below the suction cup mechanism 47. At this point, high-pressure gas is supplied using the air tank 38, causing the cylinder 46 to drive the hanging plate 471 to descend. This allows the two suction pipes 474 at the bottom of each of the four suction cup mounting plates 472 to press against the top of the pressed shoe body within the sole positioning through holes 28 on the sole mold plate 27. Then, the vacuum pump connected to one end of the suction pipe 474 is activated, allowing air to be drawn in using the suction pipes 474 that run through all the vacuum suction cups 473, firmly holding the shoe body in place. Finally, the cylinder 46 is activated to lift the hanging plate 471. The pressed shoe body can then be removed from the shoe sole positioning through hole 28 in the shoe sole mold plate 27. After removal, the slider 44 is moved to the left by the pneumatic linear slide rail 43 driven by the high pressure gas of the air tank 38. The mounting plate 45 can then move the overall cylinder 46 and suction cup mechanism 47 to the left to complete the unloading of the shoe body. After stopping the vacuum pump, the vacuum state of the vacuum suction cup 473 can be released, causing the four shoe bodies to fall. Then, the hanging plate 471 can be reset again under the drive of the pneumatic linear slide rail 43, waiting for the next pressed shoe sole on the shoe sole mold plate 27 to rotate over.

[0029] The working principle of this sole pressing device will be explained in detail below.

[0030] like Figure 1-5As shown, when pressing the sole and upper together, simply glue the sole and upper together beforehand, and place the sole into the four positioning holes 28 on the top sole mold plate 27 of the mold base plate 25. Then, the encoder 23 can precisely control the speed and rotation angle of the servo motor 22, causing it to rotate at a preset 90-degree angle until one of the four sole mold plates 27 reaches the pressing position and stops. Simultaneously, all four sole mold plates 27 on the top of the mold base plate 25 can be pulled upwards and removed for easy replacement with sole mold plates 27 of different sizes. Positioning rods 29 are aligned with positioning holes 26 and inserted into the mold plates 27 for easy installation of different sizes. The positioning of the shoe size and sole is achieved when the sole mold plate 27, containing the glued upper and sole, rotates and moves below the heating plate 35. At this point, the hydraulic cylinder 33 on the top of the extension plate 32 is activated, causing the pressing plate 34 to descend. Before descent, the heating plate 35 is heated via a wire connection between the heating power supply 36 and the heating plate 35. When the pressing plate 34 descends, it, in conjunction with the heated plate 35, presses the sole and upper together within the sole positioning through-hole 28 of the sole mold plate 27, ensuring a firm bond. Stability is maintained when the pressing plate 34 descends and rises using the sliding of the limiting slide rod 37 and the extension plate 32. After pressing, the sole mold plate 27 can continue to move... The process involves rotating the mold plate 27 containing the sole and upper, causing it to rotate 90 degrees and move below the heating plate 35. This process is repeated for rapid pressing. After pressing, the mold plate 27, rotated 90 degrees, moves directly below the suction cup mechanism 47. At this point, high-pressure gas is supplied using the air tank 38, causing the cylinder 46 to drive the hanging plate 471 downwards. This allows the two suction pipes 474 at the bottom of each of the four suction cup mounting plates 472 to press against the top of the pressed shoe body within the sole positioning through-holes 28 of the mold plate 27. Then, the vacuum pump connected to one end of the suction pipe 474 is activated, allowing the suction pipes 474, which run through all the vacuum suction cups 473, to... Inhale to firmly hold the shoe body in place, then activate cylinder 46 to lift hanging plate 471, allowing the pressed shoe body to be removed from the shoe sole positioning through hole 28 in the shoe sole mold plate 27. After removal, the slider 44 is moved to the left by the pneumatic linear slide rail 43 driven by high-pressure gas from the air tank 38. The mounting plate 45 then moves the entire cylinder 46 and suction cup mechanism 47 to the left, completing the unloading of the shoe body. After stopping the vacuum pump, the vacuum state of the vacuum suction cup 473 is released, causing the four shoe bodies to fall. Then, hanging plate 471 is reset under the drive of pneumatic linear slide rail 43, waiting for the next pressed shoe sole on the shoe sole mold plate 27 to rotate over.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
