Description

Technical Field

[0001] This utility model relates to the technical field of shoe sole grinding equipment, and in particular to a shoe sole edge grinding machine with dual grinding wheels that can switch between forward and reverse rotation. Background Technology

[0002] In the shoe sole production process, to achieve aesthetic or conformal requirements to the upper, the edges of the sole usually need to be sanded. Existing sole edge sanding machines have relatively limited functionality, typically only capable of sanding in one direction. For processes requiring coarse and fine sanding, it is often necessary to change equipment or grinding wheels. Sanding grooved soles may result in burrs, requiring secondary processing. Furthermore, it is impossible to optimize the sanding effect of grinding wheels with different roughness by changing the relative movement direction of the sanding, leading to low processing efficiency and insufficient flexibility. Utility Model Content

[0003] (1) Technical solution To address the aforementioned technical problems, this utility model provides a shoe sole edge grinding machine with dual grinding wheels that can switch between forward and reverse rotation. The machine includes a frame, a pressing mechanism, a grinding seat, a first mounting frame, a second cylinder, a first motor, a grinding mechanism, and a translation mechanism. The pressing mechanism is mounted on the top of the first mounting frame, and the grinding seat is located directly below the pressing mechanism to support the shoe sole. The first motor, which drives the grinding seat to rotate, is mounted on the bottom of the first mounting frame. The first motor can drive the grinding seat to rotate forward and backward. The second cylinder, which drives the first mounting frame, the pressing mechanism, the grinding seat, and the first motor to move left and right as a whole, is mounted on the frame. The grinding mechanism is located on one side of the grinding seat. The translation mechanism, which drives the grinding mechanism to move back and forth, is mounted on the side of the frame closest to the grinding mechanism to switch the working positions of different grinding wheels.

[0004] Preferably, the pressing mechanism includes a first cylinder, a first piston rod, and a pressing head. The first cylinder is mounted on the top of the first mounting bracket, and the first piston rod of the first cylinder is arranged downwards with its lower end passing through the top of the first mounting bracket and connected to the pressing head.

[0005] Preferably, the end of the second piston rod of the second cylinder away from the second cylinder faces the first mounting bracket and is connected to the first mounting bracket, and the bottom of the grinding seat is connected to the output shaft of the first motor.

[0006] Preferably, the grinding mechanism includes a second mounting bracket, a first rotating shaft, a first grinding wheel, a second rotating shaft, a second grinding wheel, a second motor, a third motor, a first drive mechanism, and a second drive mechanism. The first rotating shaft and the second rotating shaft are vertically and parallelly mounted on the second mounting bracket. The first grinding wheel is fixedly connected to the upper end of the first rotating shaft, and the second grinding wheel is fixedly connected to the upper end of the second rotating shaft. The second motor drives the first rotating shaft to rotate through the first drive mechanism, and the third motor drives the second rotating shaft to rotate through the second drive mechanism. The first grinding wheel and the second grinding wheel have different roughnesses; one is a coarse grinding wheel for coarse grinding, and the other is a fine grinding wheel for fine grinding.

[0007] Preferably, the first drive mechanism includes a first pulley, a second pulley, and a first belt. The lower end of the first rotating shaft is fixedly connected to the first pulley, the output shaft of the second motor is fixedly connected to the second pulley, and the first belt connects the first pulley and the second pulley.

[0008] Preferably, the second drive mechanism includes a third pulley, a fourth pulley, and a second belt. The lower end of the second rotating shaft is fixedly connected to the third pulley, the output shaft of the third motor is fixedly connected to the fourth pulley, and the second belt connects the third pulley and the fourth pulley.

[0011] (2) Beneficial effects This utility model provides a shoe sole edge grinding machine with dual grinding wheels that can switch between forward and reverse rotation. Compared with the prior art, this utility model has the following advantages: 1. By setting up two grinding wheels with different roughnesses and controlling the first motor driving the grinding seat to switch between forward and reverse rotation, the forward rotation of the grinding seat matches one grinding wheel (such as a coarse grinding wheel) for rough grinding, while the reverse rotation matches the other grinding wheel (such as a fine grinding wheel) for fine grinding with a small margin remaining after rough grinding. This design allows the rough grinding and fine grinding processes to be completed continuously on the same machine through a simple rotation switch, without the need to change grinding wheels. The process is compact, significantly improving processing efficiency and grinding quality, while also avoiding the generation of burrs on the groove surface of the shoe sole after grinding.

[0012] 2. By changing the rotation direction of the grinding seat to adapt to different processes, the structure of the grinding mechanism can be relatively simplified (the two grinding wheels can maintain rotation in a single direction). At the same time, the difference in relative motion under different directions can be used to obtain better grinding results, making it highly adaptable.

[0013] 3. The second cylinder drives the shoe sole workpiece to move left and right, and combined with the rotation of the grinding seat, it can achieve uniform grinding of the shoe sole edge from all directions, with a high degree of automation and good grinding quality.

Detailed Implementation

[0018] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0019] like Figures 1-3As shown, the present invention discloses a dual-grinding wheel forward / reverse switching shoe sole edge grinding machine, comprising a frame 1, a pressing mechanism 2, a grinding seat 3, a first mounting frame 4, a second cylinder 5, a first motor 6, a grinding mechanism 7, and a translation mechanism 8. The pressing mechanism 2 is mounted on the top of the first mounting frame 4, and the grinding seat 3 is located directly below the pressing mechanism 2. The first motor 6, which drives the grinding seat 3 to rotate, is mounted on the bottom of the first mounting frame 4. The first motor 6 can be controlled to rotate forward and reverse, thereby driving the grinding seat 3 to rotate forward or reverse. For example, forward rotation can be set to coarse grinding mode, and reverse rotation to fine grinding mode. The second cylinder 5, which drives the first mounting frame 4 to move left and right, is mounted on the frame 1. The grinding mechanism 7 is located on one side of the grinding seat 3, and the translation mechanism 8, which drives the grinding mechanism 7 to move back and forth, is mounted on the side of the frame 1 closest to the grinding mechanism 7.

[0020] The sole pressing mechanism 2 includes a first cylinder 21, a first piston rod 22, and a pressing head 23. The first cylinder 21 is mounted on the top of the first mounting frame 4. The first piston rod 22 of the first cylinder 21 is set downward and its lower end passes through the top of the first mounting frame 4 and is connected to the pressing head 23 for pressing down and fixing the sole.

[0021] The end of the second piston rod 51 of the second cylinder 5 away from the second cylinder 5 faces the first mounting bracket 4 and is connected to the first mounting bracket 4. The bottom of the grinding seat 3 is connected to the output shaft of the first motor 6.

[0022] The grinding mechanism 7 includes a second mounting bracket 71, a first rotating shaft 72, a first grinding wheel 73, a second rotating shaft 74, a second grinding wheel 75, a second motor 76, a third motor 77, a first drive mechanism 78, and a second drive mechanism 79. The first rotating shaft 72 and the second rotating shaft 74 are vertically and parallelly mounted on the second mounting bracket 71. The first grinding wheel 73 is fixedly connected to the upper end of the first rotating shaft 72, and the second grinding wheel 75 is fixedly connected to the upper end of the second rotating shaft 74. The second motor 76 drives the first rotating shaft 72 to rotate through the first drive mechanism 78, and the third motor 77 drives the second rotating shaft 74 to rotate through the second drive mechanism 79. The first grinding wheel 73 and the second grinding wheel 75 have different roughnesses. The first grinding wheel 73 and the second grinding wheel 75 are selected with different roughnesses and can be used to match different turning modes of the grinding seat.

[0023] The first drive mechanism 78 includes a first pulley 781, a second pulley 782, and a first belt 783. The lower end of the first rotating shaft 72 is fixedly connected to the first pulley 781, the output shaft of the second motor 75 is fixedly connected to the second pulley 782, and the first belt 783 is connected between the first pulley 781 and the second pulley 782.

[0024] The second drive mechanism 79 includes a third pulley 791, a fourth pulley 792, and a second belt 793. The lower end of the second rotating shaft 74 is fixedly connected to the third pulley 791, and the output shaft of the third motor 77 is fixedly connected to the fourth pulley 792. The second belt 793 connects the third pulley 791 and the fourth pulley 792.

[0025] The translation mechanism 8 includes a translation bracket 81, a third cylinder 82, a third piston rod 83, two horizontally parallel slide rails 84 mounted on one side of the frame 1, and a slider 85 horizontally slidably connected within the slide rails 84. The bottom of the translation bracket 81 is fixedly connected to the top of the slider 85. The third cylinder 82 is mounted on the frame 1 below the translation bracket 81. The end of the third piston rod 83 of the third cylinder 82 away from the third cylinder 82 is positioned towards the translation bracket 81 and connected to the bottom of the translation bracket 81. The top of the translation bracket 81 is connected to the bottom of the second mounting bracket 71 via a connecting rod 9. Thus, the linear motion of the third cylinder 82 is transmitted to the grinding mechanism 7, enabling it to move back and forth to switch between the first grinding wheel and the second grinding wheel.

[0026] A slide rod 10 is horizontally mounted on each side of the frame 1 on the second cylinder 5. A slide block 11 is slidably connected to the slide rod 10, and the top of the slide block 11 is connected to the bottom of the first mounting frame 4. This structure enhances the stability of the first mounting frame when it moves left and right.

[0027] Working principle: The core working process of this utility model is to switch the working positions of the two grinding wheels through a translation mechanism, and in conjunction with the forward and reverse rotation of the grinding seat, to complete rough and fine grinding sequentially. The specific steps are as follows: Initial clamping: Place the shoe sole to be polished on the polishing base 3, start the bottom pressing mechanism 2, and the first cylinder 21 drives the pressure head 23 to press down, firmly fixing the shoe sole on the polishing base 3.

[0028] Rough sanding stage: Grinding wheel positioning: The third cylinder 82 of the translation mechanism 8 is activated, driving the translation bracket 81 through the third piston rod 83, which in turn moves the entire grinding mechanism 7 along the slide rail 84 until the first grinding wheel (coarse grinding wheel) 73 is precisely positioned on the outer edge of the sole to be ground on the grinding seat 3. Once in position, the third cylinder 82 locks, and the coarse grinding wheel remains in this fixed position.

[0029] Grinding begins: The first motor 6 drives the grinding seat 3 and the sole to rotate clockwise (defined as the coarse grinding direction). At the same time, the second motor 76, which drives the coarse grinding wheel, starts, causing the coarse grinding wheel to rotate at high speed.

[0030] Grinding process: With the coarse grinding wheel fixed in place, the second cylinder 5 drives the first mounting bracket 4 and all its components (including the fixed sole) to move back and forth. This allows the rotating edge of the sole to continuously and evenly contact the fixed rotating coarse grinding wheel, achieving coarse grinding of the entire sole edge.

[0031] Switch to the fine polishing stage: Coarse grinding stops: After coarse grinding is completed, the first motor 6 (grinding base) and the second motor 76 (coarse grinding wheel) stop rotating.

[0032] Grinding wheel switching: The third cylinder 82 of the translation mechanism 8 actuates again, driving the grinding mechanism 7 to move, causing the first grinding wheel (coarse grinding wheel) 73 to move away from the working position, while simultaneously moving the second grinding wheel (fine grinding wheel) 75 to the outer edge of the shoe sole to be ground on the grinding seat 3. After it is in place, the third cylinder 82 locks again, and the fine grinding wheel remains in this fixed position.

[0033] Refined polishing stage: Grinding begins: The first motor 6 drives the grinding seat 3 and the sole to rotate in reverse (defined as the fine grinding direction). At the same time, the third motor 77, which drives the fine grinding wheel, starts, causing the fine grinding wheel to rotate at high speed.

[0034] Grinding process: Similar to the rough grinding process, the second cylinder 5 drives the sole to move back and forth. The rotating edge of the sole contacts the rotating fine grinding wheel in a fixed position, completing the fine grinding and finishing of the edge.

[0035] Processing complete: After the fine grinding is finished, all motors stop, the bottom pressing mechanism 2 lifts up to release the shoe sole, and the workpiece is removed, thus completing a complete cycle.

[0036] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
