Description

Technical Field

[0001] The utility model belongs to the technical field of shoe production devices and specifically discloses a sole grinding machine. Background Art

[0002] In the shoemaking industry, in order to improve the adhesion between the sole and the upper and improve product quality, almost all soles must be polished. For example, the patent with announcement number CN211065253U discloses a sole polishing device, which uses a fixing mechanism to replace manual sole holding, and then cooperates with a moving mechanism and a polishing mechanism to replace manual polishing, thereby avoiding the danger of manual operation. Although the above patent does not require manual sole holding, it still requires manual sole picking and fixing each time it is polished, resulting in low production efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a sole grinding machine. The sole grinding machine of the present invention can improve work efficiency.

[0004] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a sole grinding machine, comprising a main body, a feeding structure, a power unit and a grinding structure, the grinding structure is located at the rear side of the main body, the grinding structure comprises a grinding roller and a moving part for driving the sole to move, the moving part comprises a plurality of rotating rollers rotatably connected to the main body, the grinding rollers are rotatably connected to the main body, and the grinding rollers and the rotating rollers are respectively driven to rotate by the power unit;

[0005] The feeding structure is located at the front end side of the main body, and the feeding structure includes a reciprocating mechanism, a connecting rod and two feeding plates. Notches are provided at the lower ends of the two feeding plates. The two feeding plates are vertically arranged and a feeding channel is formed between the two feeding plates. A baffle is provided under the feeding channel, and the baffle is fixedly connected to the main body; a strip groove is provided in the middle of the baffle; the connecting rod is vertically arranged and driven to move by the reciprocating mechanism; a shifting rod is provided at the upper end of the connecting rod, and the shifting rod is hinged to the connecting rod, and a torsion spring is provided at the hinge between the shifting rod and the connecting rod.

[0006] The working principle and beneficial effect of adopting this basic scheme are as follows: when the sole grinder of this scheme is adopted, the soles to be grinded are stacked and placed at the feeding structure, that is, the stacked soles are placed in the feeding channel, and the two feeding plates of the feeding structure can perform preliminary positioning on the stacked soles, so that the soles will not fall or scatter. Then the entire sole grinder is started. When starting, the reciprocating mechanism of the feeding structure is started first. After the reciprocating mechanism is started, the connecting rod is driven to move toward the main body. As the reciprocating mechanism continues to push the connecting rod to move, the connecting rod drives the bottom sole to pass through the notch and move toward the main body of the grinder through the lever, and pushes the bottom sole to the main body of the grinder. When the reciprocating mechanism pushes the connecting rod to move to the limit position, the sole moves to the moving part, and the sole at the feeding structure also moves downward to the top of the baffle due to gravity. The reciprocating mechanism drives the connecting rod to move in the opposite direction. During the movement, the lever contacts the bottom sole, but the lever cannot move the sole due to the action of the baffle. At this time, the lever rotates and enters the strip groove, and the torsion spring deforms and stores energy. After the lever passes under the sole, it returns to the initial position under the action of the torsion spring, that is, the lever passes through the strip groove again. The reciprocating mechanism continues to push the connecting rod to move toward the main body, and the lever drives the next sole to enter the moving part.

[0007] After the sole moves to the moving part, the power part drives the moving part to work, that is, the roller rotates to move the sole along the main body. During the movement, the sole will also move to the grinding roller and be polished by the grinding roller to complete the grinding work on the lower end surface of the sole.

[0008] The sole grinding device of the present invention can realize automatic feeding and grinding, and does not need to manually place the soles one by one, thereby improving work efficiency.

[0009] Furthermore, a polishing roller is provided at the rear of the main body, which is vertically arranged and rotatably connected to the main body. When the moving part drives the sole to move to the polishing roller, the polishing roller can also polish the side of the sole, thereby improving the polishing effect of the sole.

[0010] Furthermore, the reciprocating structure has a first cylinder and a connecting plate, the output shaft of the first cylinder is connected to the connecting plate, and there are two connecting rods, which are respectively located on both sides of the upper end of the connecting plate and connected to the connecting plate. The output shaft of the first cylinder is controlled to extend or retract to achieve the reciprocating movement of the connecting rod. Moreover, the number of connecting rods is set to two, which can make the lever push the sole to move more smoothly and prevent the sole from rotating when pushing.

[0011] Furthermore, the invention also includes a pressing structure for pressing the sole, which can move back and forth laterally along the main body. The pressing structure can be provided to press the sole when the grinding roller is grinding the sole, thereby increasing the force applied to the sole by the grinding roller during grinding.

[0012] Furthermore, the pressing structure includes a second cylinder, and the output shaft of the second cylinder is provided with a pressing plate. When pressing the sole, the output shaft of the second cylinder extends and drives the pressing plate to move downward until the pressing plate contacts the sole and applies pressure to the sole, thereby increasing the force between the grinding roller and the sole and improving the grinding effect.

[0013] Furthermore, it also includes a first gear, a second gear and a rack; the first gear and the second gear are respectively connected to the main body for rotation, the first gear is driven to rotate by the power unit, and the chain passes by the first gear and the second gear and meshes with the first gear and the second gear; the chain is fixed with a fixed plate, and the cylinder is connected to the fixed plate. After the power unit drives the first gear to rotate, because the chain meshes with the first gear and the second gear, when the first gear rotates, the chain moves laterally along the main body. The fixed plate connected to the chain will also move laterally along the main body, and drive the second cylinder and the pressing plate to move. The sole pressed by the pressing plate will move along the rotating roller and the grinding roller to complete the grinding of the lower end surface of the sole. After the grinding is completed, the power unit rotates in the opposite direction and drives the first gear to rotate in the opposite direction. At this time, the chain also moves in the opposite direction, driving the second cylinder to move to the feeding structure again to press the new sole.

[0014] Furthermore, it also includes a guide rail, which is arranged horizontally and connected to the main body, and the fixing plate is slidably matched with the guide rail. The guide rail can make the chain drive the second cylinder to move more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

The lower ends of the two feeding plates 4 are each provided with a notch 7. The two feeding plates 4 are vertically arranged and a feeding channel 5 is formed between the two feeding plates 4. A baffle 1 is provided below the feeding channel 5, and the baffle 1 is fixedly connected to the main body 2; a strip groove is provided in the middle of the baffle 1; the connecting rod 19 is vertically arranged and driven to move by the reciprocating mechanism; a shifting rod 18 is provided at the upper end of the connecting rod 19, and the shifting rod 18 is hinged to the connecting rod 19, and a torsion spring (not drawn in the figure) is provided at the hinge between the shifting rod 18 and the connecting rod 19.

[0022] The reciprocating structure includes a first cylinder 15, a first connecting rod 16 and a connecting plate 17, wherein the output shaft of the first cylinder 15 is connected to one end of the first connecting rod 16, and the other end of the first connecting rod 16 is connected to the connecting plate 17. There are two connecting rods 19, which are respectively located on both sides of the upper end of the connecting plate 17 and connected to the connecting plate 17. The number of connecting rods 19 is set to two, which can make the lever 18 push the sole to move more smoothly and prevent the sole from rotating when pushing.

[0023] The shoe sole grinding machine in this embodiment also includes a clamping structure for clamping the sole, and the clamping structure can move back and forth laterally along the main body 2. The clamping structure includes a second cylinder 12, and the output shaft of the second cylinder 12 is connected to a second connecting rod 13, and a pressing plate 14 is provided at the lower end of the second connecting rod 13, which can be connected by welding or bolting. The shoe sole grinding machine in this embodiment also includes a guide rail 3, a first gear 6, a second gear and a chain 10; the first gear 6 and the second gear are respectively rotatably connected to the main body 2, the first gear 6 is driven to rotate by the power unit, and the chain 10 bypasses the first gear 6 and the second gear and meshes with the first gear 6 and the second gear; the chain 10 is fixed with a fixing plate 11, and the second cylinder is connected to the fixing plate 11. The guide rail 3 is arranged laterally and connected to the main body 2, and the fixing plate 11 is slidably matched with the guide rail 3.

[0024] The power unit in this embodiment is a servo motor, and the number of servo motors can be set as needed. In this embodiment, the number of servo motors is two, and the two servo motors respectively drive the rotating roller / grinding roller 8 to rotate and drive the first gear 6 to rotate.

[0025] The specific implementation is as follows: When the sole grinding machine of the present scheme is adopted, the soles to be ground are stacked and placed at the feeding structure, that is, the stacked soles are placed in the feeding channel 5, and the two feeding plates 4 of the feeding structure can perform preliminary positioning on the stacked soles, so that the soles will not fall or scatter. Then the entire sole grinding machine is started. When starting, the reciprocating mechanism of the feeding structure is started first. That is, the first cylinder 15 is started first, so that the output shaft of the first cylinder 15 extends, and the output shaft of the first cylinder extends and drives the connecting rod to move. As the reciprocating mechanism continues to push the connecting rod 19 to move, the connecting rod 19 drives the bottom sole to pass through the notch 7 and move toward the grinding machine body 2 through the lever 18, and pushes the bottom sole to the grinding machine body 2. When the output shaft of the first cylinder 15 pushes the connecting rod 19 to move to the limit position, the sole moves to the moving part, and the sole at the feeding structure also moves downward to the top of the baffle 1 due to gravity. The first cylinder 15 drives the connecting rod 19 to move in the opposite direction. During the movement, the lever 18 contacts the bottom sole, but cannot move the sole due to the action of the baffle 1. At this time, the lever 18 rotates and enters the strip groove, and the torsion spring deforms and stores energy. After the lever 18 passes under the sole, it returns to the initial position under the action of the torsion spring, that is, the lever 18 passes through the strip groove again. The first cylinder 15 continues to push the connecting rod 19 to move toward the main body 2, and the lever 18 drives the next sole to enter the moving part.

[0026] After the sole moves to the moving part, the power unit drives the moving part to work, that is, the rotating roller rotates to move the sole along the main body 2. The output shaft of the second cylinder 12 extends and drives the pressing plate 14 to move downward until the pressing plate 14 contacts the sole and applies pressure to the sole. After the power unit drives the first gear 6 to rotate, because the chain 10 is meshed with the first gear 6 and the second gear, when the first gear 6 rotates, the chain 10 moves laterally along the main body 2. The fixed plate 11 connected to the chain 10 will also move laterally along the main body 2, and drive the second cylinder 12 and the pressing plate 14 to move. The sole pressed by the pressing plate 14 will move along the rotating roller and the grinding roller 8 to complete the grinding of the lower end surface of the sole. After the grinding is completed, the power unit rotates in the opposite direction and drives the first gear 6 to rotate in the opposite direction. At this time, the chain 10 also moves in the opposite direction, driving the second cylinder 12 to move to the feeding structure again to press the new sole.

[0027] During the movement, the sole will also move to the grinding roller 8 and be polished by the grinding roller 8, completing the polishing of the lower end surface of the sole. The pressing structure can be provided to press the grinding roller 8 when the sole is polished, thereby increasing the force applied to the sole by the grinding roller 8. This in turn increases the force applied between the grinding roller 8 and the sole, thereby improving the polishing effect.

[0028] When the moving part drives the sole to move to the polishing roller 9, the polishing roller 9 can also polish the side of the sole, thereby improving the polishing effect of the sole. The guide rail 3 can make the chain 10 drive the second cylinder 12 to move more smoothly.
