[0021] Example

[0022] like Figures 1-4 As shown, a shoe sole pressing and forming device for shoe production includes a frame 1, on which two horizontally arranged rotating rollers 2 are symmetrically mounted, and a conveyor belt 3 is wound around the two rotating rollers 2. A first motor 4 is also mounted on the frame 1, and the output shaft of the first motor 4 is drivenly connected to one of the rotating rollers 2, thereby realizing the rotation of the conveyor belt 3, which is used to convey uncut material of shoe sole.

[0023] A hydraulic cylinder 5 is also fixedly installed on the frame 1. The hydraulic cylinder 5 is located above the conveyor belt 3. The telescopic rod of the hydraulic cylinder 5 is set vertically downward and its end is connected to a horizontally set connecting plate 51. A first mounting block 61 and a second mounting block 62 are respectively fixed to the two opposite side walls of the connecting plate 51.

[0024] like Figures 2-3 As shown, a cutting frame 8 for shaping and cutting large pieces of shoe sole material is detachably mounted on the bottom of the first mounting block 61. A grinding component for grinding the shoe sole material cut by the cutting frame 8 is mounted on the bottom of the second mounting block 62. The cutting frame 8 and the grinding component are both located directly above the conveyor belt 3 and are arranged side by side at intervals along the conveying direction of the conveyor belt 3. Driven by the hydraulic cylinder 5, the cutting frame 8 and the grinding component can move down synchronously to the upper surface of the conveyor belt 3, realizing the simultaneous operation of cutting and shaping the shoe sole material and grinding the cut shoe sole material.

[0025] like Figures 2-3 As shown, the cutting frame 8 is a hollow frame with its outer sidewalls forming the shape of a shoe sole, and its bottom edge is a sharp blade for cutting the sole material. The sidewalls of the cutting frame 8 slope inward from top to bottom, which facilitates the removal of the sole material from the cutting frame 8 after cutting and reduces burrs and tearing during the cutting process.

[0026] A first groove 611, vertically positioned and opening at its bottom, is provided within the first mounting block 61. A first top block 14, with an inverted "T" shaped cross-section, is elastically slidably inserted into the first groove 611. The first top block 14 consists of a first guide rod 141 slidably inserted into the first groove 611 and a first plate 142, with a diameter larger than the first groove 611 and located within the cutting frame 8. A first spring 151 is also sleeved around the outer periphery of the first guide rod 141, with its two ends connected to the inner wall of the first groove 611 and the surface of the first plate 142, respectively. Under normal conditions, the first plate 142 is spaced apart from the bottom surface of the first mounting block 61. When the cutting frame 8 moves downward to cut the sole material, the first top block 14 elastically moves upward and presses against the upper surface of the sole material. When the cutting frame 8 rises, the first top block 14 elastically resets and moves downward, thereby pushing the sole material out of the cutting frame 8.

[0027] like Figures 2-4 As shown, the grinding assembly includes a mounting frame 7 fixedly connected to the bottom surface of the second mounting block 62 and a guide ring 12 mounted below the mounting frame 7. The guide ring 12 is a hollow frame. The interior of the mounting frame 7 is hollow, and several rotatable shafts 9 are vertically mounted inside. Each shaft 9 passes through the bottom wall of the mounting frame 7 and extends into the interior of the guide ring 12. The portions of the shafts 9 extending into the guide ring 12 are wound around a synchronous belt 10. A sanding belt 11 is connected to the bottom side of the synchronous belt 10, and the bottom horizontal position of the sanding belt 11 is lower than the bottom horizontal position of the shafts 9. The sanding belt 11 is arranged around the inner wall of the guide ring 12. The shape of the guide ring 12 is consistent with the shape of the cutting frame 8, and the inner diameter of the sanding belt 11 after it is wound around the inner wall of the guide ring 12 is not less than the inner diameter of the cutting frame 8.

[0028] The mounting frame 7 houses a second motor 13, whose output shaft is connected to one of the rotating shafts 9, thereby enabling the sanding belt 11 to rotate and sand the cut shoe sole material 100.

[0029] A second top block 16 with an "I"-shaped cross-section is elastically slidably inserted into the mounting frame 7. The second top block 16 includes a second guide rod 161 that is slidably and vertically inserted into the bottom wall of the mounting frame 7, a second upper limit plate 162 connected to the top end of the second guide rod 161 and constrained within the mounting frame 7, and a second lower limit plate 163 connected to the bottom end of the second guide rod 161 and constrained below the mounting frame 7. A second spring 152 is also sleeved on the outer periphery of the second guide rod 161, and the two ends of the second spring 152 are respectively connected to the bottom surface of the second upper limit plate 162 and the inner side of the bottom wall of the mounting frame 7. Under normal conditions, the second lower limit plate 163 and the bottom surface of the mounting frame 7 are spaced apart. When the guide ring 12 moves down, the cut sole material 100 is framed inside it. The sanding belt 11 is wrapped around the outer periphery of the sole material 100 and rotates to grind it. The second top block 16 will elastically move up and press on the upper surface of the sole material 100. When the guide ring 12 rises, the second top block 16 will elastically reset and move down, thereby pushing the sole material 100 out of the guide ring 12.

[0030] like Figures 1-2 As shown, a support plate 18 is fixedly connected to the middle of the frame 1. The support plate 18 is horizontally arranged on the bottom surface of the upper layer of the conveyor belt 3 and is located directly below the cutting frame 8 and the grinding assembly, and is used to support the downward pressure of the cutting frame 8 and the grinding assembly.

[0031] Working Principle: When using this equipment to press-cut and form shoe soles for shoe production, the equipment is first started. The conveyor belt 3 starts to operate under the drive of the first motor 4. The raw material is evenly placed on the conveyor belt 3 by the worker and moves forward with the conveyor belt 3. When the raw material reaches the position of the pressing frame 8, the first motor 4 is turned off. At the same time, the hydraulic cylinder 5 located at the top of the frame 1 starts to work. The extension rod of the hydraulic cylinder 5 pushes the connecting plate 51 downward in sync, causing the pressing frame 8 and the grinding component to move downward, and the pressing frame 8 cuts the material. After the cutting is completed, the hydraulic cylinder 5 resets and retracts, and the first motor 4 is turned on again so that the conveyor belt 3 continues to transport the cut shoe sole material 100. When the shoe sole material 100 is transported to the preset distance, it is also located directly below the guide ring 12. The first motor 4 is turned off again and the hydraulic cylinder 5 is turned on. The shoe sole material 100 that was previously cut by the pressing frame 8 is pressed into the guide ring 12 to be ground by the sanding belt 11. At the same time, the pressing frame 8 cuts a new shoe sole material downward. This process is repeated continuously, allowing for simultaneous pressing, cutting, and polishing of the shoe soles.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
