Abstract

This invention relates to the field of rubber shoe technology and discloses a rubber shoe sole edge grinding device, including a base plate. A slide, a backrest bar, and a side plate are fixedly installed on the top of the base plate. A pair of sliders are slidably installed on the right side of the side plate. An extension plate is fixedly installed on the right side of the sliders. A No. 3 motor is fixedly installed on the opposite side of the extension plate. A template is fixedly connected to the output shaft of the No. 3 motor. A moving block is slidably installed on the top of the slide. When the No. 3 motor is started, it drives the rubber insole clamped on the template to rotate. At the same time, the No. 5 motor is started to drive the grinding disc to rotate through gears. When the template rotates, the guide wheel will move left and right according to the linear shape of the template's outer wall, thereby driving the grinding disc to grind according to the outer circumference of the template.

Description

Technical Field

[0001] This invention relates to the field of rubber shoe technology, specifically to a device for grinding the edge of rubber shoe soles. Background Technology

[0002] Rubber soles are shoe soles made of rubber. Rubber sole materials can be broadly categorized into natural rubber and synthetic rubber. Natural rubber is advantageous because it is very soft, has excellent elasticity, is suitable for various sports, and provides shock absorption. Indoor sports shoes often use natural rubber. Synthetic rubber is further divided into abrasion-resistant rubber, environmentally friendly rubber, air-filled rubber, tacky rubber, hard rubber, and carbon-reinforced rubber. During the processing of rubber soles, excess burrs or processing allowances need to be removed from the edges to avoid affecting the product's appearance, subsequent processing, and quality. Currently, burrs on rubber soles are removed by grinding.

[0003] For example, patent publication number CN215921070U discloses a rubber shoe sole burr removal device, including a base plate, a side plate fixedly connected to the top right of the base plate, a top plate fixedly connected to the top of the side plate, a motor fixedly connected to the top left of the base plate, and an electric telescopic rod fixedly connected to the bottom left of the top plate. This utility model relates to the field of rubber shoe sole technology. This rubber shoe sole burr removal device, by pulling down the movable frame, eventually disengages the movable frame from the baffle. At this time, rotating the baffle unlocks the second connecting seat, and finally pulling the second connecting seat backward causes the slider to disengage from the inner cavity of the slide groove, thereby completing the template disassembly operation. Conversely, when the template needs to be reassembled, simply reverse the above steps. Different sizes of templates can be used to complete the trimming for different rubber shoe soles. This rubber shoe sole burr removal device has the advantage of easy disassembly and assembly.

[0004] In the process of developing this application, the following problems were discovered with this technology: the device uses a spring sleeved on a T-shaped rod to ensure that the grinding disc and the template below are always in close contact when the rubber sole rotates, thereby achieving grinding of the sole edge. However, because the grinding disc is in close contact with the template, this design causes the grinding disc to grind the template while grinding the sole, which in turn damages the edge of the template. Over time, this can lead to template deformation, ultimately affecting the grinding size deviation of the sole. In order to solve the above-mentioned problems, this invention provides a rubber shoe sole edge grinding device. Summary of the Invention

[0012] In a preferred embodiment of the invention, a second slide groove adapted to the slider is provided on the right side of the side plate, a first threaded rod with opposite upper and lower threaded surfaces is threaded onto the slider, and a second motor fixedly installed on the top of the side plate and fixedly connected to the top of the first threaded rod.

[0013] In a preferred embodiment of the invention, the top of the slide block is provided with a third sliding groove adapted to the moving block, a guide rod is inserted and installed on the moving block, and a return spring is sleeved on the outer periphery of the guide rod.

[0014] In a preferred embodiment of the invention, the left side of the adjusting plate is provided with a No. 4 sliding groove adapted to the adjusting block, the adjusting block is threadedly connected with a No. 2 threaded rod with opposite upper and lower threaded surfaces, and the top of the adjusting plate is fixedly mounted with a No. 4 motor that is fixedly connected to the top of the No. 2 threaded rod.

[0015] In a preferred embodiment of the invention, the two guide wheels are located above and below the grinding disc, respectively.

[0017] In a preferred embodiment of the invention, a No. 6 motor is fixedly installed inside the vibrator, and a U-shaped rod is fixedly installed on the output shaft of the No. 6 motor. A sleeve rod is sleeved on the middle of the outer wall of the U-shaped rod, and a T-shaped plate is hinged to the left side of the sleeve rod, and the T-shaped plate is in contact with the inner wall of the collecting cylinder.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. In this invention, by setting up a mover, when it is necessary to move the device, the No. 1 motor is started to drive the lead screw to rotate, which in turn can drive the support rod to move upward and retract into the mover. At this time, the roller at the bottom of the mover contacts the ground, which can realize the movement of the device. After moving into place, the No. 1 motor is started to drive the lead screw to rotate in the opposite direction, which pushes the support rod downward from the bottom of the mover, so that the rubber anti-slip pad at the bottom of the support rod contacts the ground, which can realize the fixation of the device.

[0020] 2. In this invention, by setting an auxiliary structure on the slide block, when it is necessary to grind the edge of the rubber shoe sole, first slide the moving block on the slide block to the right, then place the shoe sole to be ground on the template below, and adjust the shoe sole to align with the template. At this time, start the second motor to drive the first threaded rod to rotate, thereby pushing the two sliders to move the two templates on the opposite surfaces of the extension plate closer together, thereby clamping and fixing the rubber shoe sole. At this time, start the fourth motor to drive the second threaded rod to rotate, thereby pushing the clamping plates on the left side of the two adjusting blocks closer together, so that the guide wheels on the opposite surfaces of the upper and lower clamping plates respectively... The rubber insole is placed close to and pressed against the right wall of the upper and lower templates. At this time, motor No. 3 is started to drive the rubber insole clamped on the template to rotate. At the same time, motor No. 5 is started to drive the grinding disc to rotate through gears. When the template rotates, the guide wheel will move left and right according to the linear shape of the outer wall of the template, thereby driving the grinding disc to grind according to the outer circumference of the template. Since the leftmost side of the guide wheel and the grinding disc are on the same vertical line, the grinding disc can only grind the part that exceeds the outer wall size of the template. This ensures that the grinding disc will not wear down the template when grinding the rubber sole, thereby improving the service life of the device.

[0021] 3. In this invention, by setting up a suction hood, when the grinding disc grinds the rubber sole, rubber debris will inevitably be generated. To prevent the debris from scattering in the air and affecting the workers, an air pump is started to suck air into the suction hood, thereby drawing the rubber debris generated by the grinding disc into the suction hood and finally discharging it into the collection cylinder through the air pump. At this time, the air will pass through the filter plate and be discharged from the right side of the exhaust ring, while the debris is blocked on the left side of the filter plate. When the grinding is finished and the debris needs to be cleaned, the sealing cover at the bottom of the collection cylinder is rotated open. Then, the No. 6 motor in the vibrator is started to drive the U-shaped rod to rotate, which in turn drives the T-shaped plate to move back and forth continuously through the sleeve rod, thereby vibrating the collection cylinder and shaking the debris inside the collection cylinder off, thus achieving the removal.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The following will combine Figures 1-5 A detailed description of a rubber shoe sole edge grinding device according to an embodiment of the present invention will be provided.

[0030] Example:

[0031] Reference Figure 1 , 2 A rubber shoe sole edge grinding device includes a base plate 1. Movers 2 are fixedly installed at all four ends of the bottom of the base plate 1. Support rods 3 are slidably installed on the outer side of the bottom of the movers 2. Multiple sets of rollers are rotatably installed in the middle of the bottom of the movers 2. Rubber anti-slip pads are provided at the bottom of the support rods 3. A first groove adapted to the support rods 3 is opened at the bottom of the movers 2. A lead screw 4 is threadedly connected to the top of the support rods 3. A first motor 5 fixedly connected to the top of the lead screw 4 is fixed inside the movers 2. A slide seat 6, a back rod 7, and a side plate 8 are fixedly installed on the top of the base plate 1. The side plate 8 is located on the left side of the slide seat 6, and the back rod 7 is located on the rear side of the slide seat 6.

[0032] By setting the mover 2, when the device needs to be moved, the first motor 5 is started to drive the lead screw 4 to rotate, which in turn moves the support rod 3 upward and retracts it into the mover 2. At this time, the roller at the bottom of the mover 2 contacts the ground, which enables the device to move. After it is moved into place, the first motor 5 is started to drive the lead screw 4 to rotate in the opposite direction, which pushes the support rod 3 downward from the bottom of the mover 2, so that the rubber anti-slip pad at the bottom of the support rod 3 contacts the ground, which can fix the device.

[0033] Reference Figure 1 , 2 3. A pair of sliders 9 are slidably mounted on the right side of the side plate 8. A second groove adapted to the sliders 9 is provided on the right side of the side plate 8. A first threaded rod 10 with opposite upper and lower threaded surfaces is threaded onto the sliders 9. A second motor 11, which is fixedly connected to the top of the first threaded rod 10, is fixedly mounted on the top of the side plate 8. An extension plate 12 is fixedly mounted on the right side of the sliders 9. A third motor 13 is fixedly mounted on the opposite side of the extension plate 12. A template 14 is fixedly connected to the output shaft of the third motor 13. A moving block 15 is slidably mounted on the top of the slide block 6. A third groove adapted to the moving block 15 is provided on the top of the slide block 6. A guide rod 16 is inserted into the moving block 15. A return spring is sleeved on the outer periphery of the guide rod 16. An adjusting plate 17 is mounted on the top of the guide rod 16. A sliding mechanism is mounted on the left side of the adjusting plate 17. A pair of adjusting blocks 18 are provided. A fourth sliding groove adapted to the adjusting block 18 is opened on the left side of the adjusting plate 17. A second threaded rod 19 with opposite upper and lower threaded surfaces is threaded onto the adjusting block 18. A fourth motor 20 fixedly connected to the top of the second threaded rod 19 is fixedly installed on the top of the adjusting plate 17. A clamping plate 21 is fixedly installed on the left side of the adjusting block 18. Guide wheels 22 are rotatably installed on the opposite surfaces of the upper and lower clamping plates 21. A grinding disc 23 is rotatably installed on the bottom of the upper clamping plate 21. The two guide wheels 22 are located above and below the grinding disc 23, respectively, and the left side of the guide wheel 22 and the left side of the grinding disc 23 are on the same vertical line. A fifth motor 24 is fixedly installed on the top of the upper clamping plate 21. Gears that mesh with each other are fixedly installed on the output shaft of the fifth motor 24 and the rotating shaft of the grinding disc 23.

[0034] By setting the auxiliary structure on the slide block 6, when it is necessary to grind the edge of the rubber shoe sole, first slide the moving block 15 on the slide block 6 to the right, then place the shoe sole to be ground on the template 14 below, and adjust the shoe sole to align with the template 14. At this time, start the second motor 11 to drive the first threaded rod 10 to rotate, which in turn pushes the two sliders 9 to move the two templates 14 on the opposite surface of the extension plate 12 closer together, thereby clamping and fixing the rubber shoe sole. At this time, start the fourth motor 20 to drive the second threaded rod 19 to rotate, which in turn pushes the clamping plates 21 on the left side of the two adjusting blocks 18 closer together, so that the guide wheels 22 on the opposite surfaces of the upper and lower clamping plates 21 are close together and pressed tightly. On the right wall of the upper and lower templates 14, motor 13 is started to rotate the rubber insole clamped on the template 14. At the same time, motor 24 is started to rotate the grinding disc 23 through gears. When the template 14 rotates, the guide wheel 22 will move left and right according to the linear shape of the outer wall of the template 14, thereby driving the grinding disc 23 to grind according to the outer circumference of the template 14. Since the leftmost side of the guide wheel 22 and the grinding disc 23 are on the same vertical line, the grinding disc 23 can only grind the part that exceeds the outer wall size of the template 14. This ensures that the grinding disc 23 will not wear down the template 14 when grinding the rubber sole, thereby improving the service life of the device.

[0035] Reference Figure 1 , 4 5. A suction hood 25 is fixedly installed on the left side of the backrest 7. An air pump 26 is fixedly installed on the top of the suction hood 25, and the inner cavity of the suction hood 25 is connected to the suction end of the air pump 26. A collection cylinder 27 is connected to the lower right side of the backrest 7 via a vibration spring. An exhaust ring 28 is fixedly connected to the left side of the collection cylinder 27. A filter plate 30 is inserted into the top of the exhaust ring 28. The collection cylinder 27 and the exhaust ring 28 are internally connected. The bottom of the connection position between the collection cylinder 27 and the exhaust ring 28 is inclined. The design includes a sealing cap threaded to the bottom of the collection cylinder 27, a nozzle 29 connected to the exhaust end of the air pump 26 placed inside the collection cylinder 27, a vibrator 31 fixedly installed on the inner wall of the collection cylinder 27, a No. 6 motor 32 fixedly installed inside the vibrator 31, a U-shaped rod 33 fixedly installed on the output shaft of the No. 6 motor 32, a sleeve rod 34 sleeved on the middle of the outer wall of the U-shaped rod 33, a T-shaped plate 35 hinged to the left side of the sleeve rod 34, and the T-shaped plate 35 fitting against the inner wall of the collection cylinder 27.

[0036] By setting up the suction hood 25, when the grinding disc 23 grinds the rubber sole, rubber debris will inevitably be generated. In order to prevent the debris from scattering in the air and affecting the workers, the air pump 26 is started to suck air into the suction hood 25, thereby sucking the rubber debris generated by the grinding disc 23 into the suction hood 25 and finally discharging it into the collection cylinder 27 through the air pump 26. At this time, the air will pass through the filter plate 30 and be discharged from the right side of the exhaust ring 28, while the debris is blocked on the left side of the filter plate 30. When the grinding is finished and the debris needs to be cleaned, the sealing cover at the bottom of the collection cylinder 27 is rotated open. Then, the No. 6 motor 32 in the vibrator 31 is started to drive the U-shaped rod 33 to rotate, which in turn drives the T-shaped plate 35 to move back and forth continuously through the sleeve rod 34, thereby vibrating the collection cylinder 27 and shaking the debris inside the collection cylinder 27 to be removed.

[0037] The implementation principle of the rubber shoe sole edge grinding device of this application is as follows:

[0038] First, by setting up the mover 2, when the device needs to be moved, the first motor 5 is started to drive the lead screw 4 to rotate, which in turn moves the support rod 3 upward and retracts it into the mover 2. At this time, the roller at the bottom of the mover 2 contacts the ground, which enables the device to move. After it is moved into place, the first motor 5 is started to drive the lead screw 4 to rotate in the opposite direction, which pushes the support rod 3 downward from the bottom of the mover 2, so that the rubber anti-slip pad at the bottom of the support rod 3 contacts the ground, which enables the device to be fixed.

[0039] Importantly, by setting the auxiliary structure on the slide block 6, when it is necessary to grind the edge of the rubber sole, first slide the moving block 15 on the slide block 6 to the right, then place the sole to be ground on the template 14 below, and adjust the sole to align with the template 14. At this time, start the second motor 11 to drive the first threaded rod 10 to rotate, which in turn pushes the two sliders 9 to move the two templates 14 on the opposite surface of the extension plate 12 closer together, thereby clamping and fixing the rubber sole. At this time, start the fourth motor 20 to drive the second threaded rod 19 to rotate, which in turn pushes the clamping plates 21 on the left side of the two adjusting blocks 18 closer together, so that the guide wheels 22 on the opposite surfaces of the upper and lower clamping plates 21 are closer together and... The rubber insole clamped on the template 14 is attached to the right wall of the upper and lower templates 14. At this time, motor 13 is started to drive the rubber insole clamped on the template 14 to rotate. At the same time, motor 24 is started to drive the grinding disc 23 to rotate through gears. When the template 14 rotates, the guide wheel 22 will move left and right according to the linear shape of the outer wall of the template 14, thereby driving the grinding disc 23 to grind according to the outer circumference of the template 14. Since the leftmost side of the guide wheel 22 and the grinding disc 23 are on the same vertical line, the grinding disc 23 can only grind the part that exceeds the outer wall size of the template 14. This ensures that the grinding disc 23 will not wear down the template 14 when grinding the rubber sole, thereby improving the service life of the device.

[0040] Furthermore, by setting up the suction hood 25, when the grinding disc 23 grinds the rubber sole, rubber debris will inevitably be generated. To prevent the debris from scattering in the air and affecting the workers, the air pump 26 is activated to suck air into the suction hood 25, thereby drawing the rubber debris generated by the grinding disc 23 into the suction hood 25 and finally discharging it into the collection cylinder 27 through the air pump 26. At this time, the air will pass through the filter plate 30 and be discharged from the right side of the exhaust ring 28, while the debris is blocked on the left side of the filter plate 30. When the grinding is finished and the debris needs to be cleaned, the sealing cover at the bottom of the collection cylinder 27 is rotated open. Then, the No. 6 motor 32 in the vibrator 31 is activated to drive the U-shaped rod 33 to rotate, which in turn drives the T-shaped plate 35 to move back and forth continuously through the sleeve rod 34, thereby vibrating the collection cylinder 27 and shaking the debris out of the collection cylinder 27, thus achieving the cleaning.
