Technical Field

[0001] This invention belongs to the field of blade grinding technology and relates to an automatic blade grinding device. Background Technology

[0002] Razors are classified by structure into safety razors, electric razors, and mechanical razors. Safety razors mainly consist of blades and a shovel-shaped handle. The handle is made of aluminum, stainless steel, copper, or plastic; the blades are made of stainless steel or carbon steel, and for sharpness and durability, the cutting edge is often treated with a metal or chemical coating. Electric razors consist of a stainless steel mesh cover, inner blades, a miniature motor, and a housing. The mesh cover, which is the fixed outer blade, has many holes through which beard hairs can be inserted. The miniature motor is powered by electricity, which drives the inner blades to move, using a shearing principle to cut the hairs inserted into the holes. Electric razors can be further divided into rotary and reciprocating types based on the movement characteristics of the inner blades.

[0003] To ensure a good shaving result, it's best to use high-performance alkaline batteries for your razor. If it's not used for an extended period, remove the batteries to prevent leakage from damaging the internal components. Also, the razor blades need to be sharpened after prolonged use to maintain their fast shaving function.

[0028] Preferably, a fixing pin is rotatably connected to the middle of the rotating lever, and the two ends of the fixing pin are respectively fixedly connected to the inner wall of the support platform.

[0029] As a preferred technical solution of the present invention, the end of the rotating lever away from the fixed sphere is fixedly connected to a fixed lug seat, and the fixed lug seat is provided with a fixed lug.

[0030] Preferably, the fixed lug and the fixed lug seat are connected by a rotating pin hinge.

[0031] Preferably, a slider is fixedly connected to the end of the fixed lug away from the fixed lug base.

[0032] Preferably, the slider is a rectangular slider.

[0033] Preferably, a fixed push rod is connected to the end of the fixed lifting lug away from the fixed lifting lug seat.

[0042] It should be noted that the torsion spring in this invention is a high-strength torsion spring, which can realize the return of the clamping plate and the blade, and is conducive to completing the function of the automatic face-changing grinding mechanism.

[0043] It should be noted that the working principle of the grinding structure in this invention includes:

[0044] The user can use a remote control to start the rotary motor, which drives the electrode shaft to rotate. The rotation of the electrode shaft drives the rotary worm gear, which in turn drives the rotary turbine, which in turn drives the second shaft. The second shaft, in turn, drives the rotating top plate, the rotating disk, and the first gear to rotate. The first gear then drives the second gear, which in turn drives the grinding disk to rotate. The grinding disk grinds the blade. Simultaneously, the rotation of the rotating top plate and the rotating disk drives the arc-shaped protrusion and the arc-shaped vertical tooth to rotate. The rotation of the arc-shaped protrusion pushes the fixed ball to one end, which in turn rotates the rotating lever. The rotation of the rotating lever then moves the fixed lifting lug to one end, which in turn moves the fixed lifting lug to one end. The movement of the rectangular slider along the fixed optical axis moves one end, which in turn moves the fixed push rod to one end. The movement of the fixed push rod to one end moves the fixed cylinder to one end, which in turn moves the connecting shaft to one end. The movement of the connecting shaft to one end causes the third gear and the blade in the clamping plate to be in a flat state and the torsion spring to be in a compressed state. At this time, the blade is disengaged from the grinding disc, and the arc-shaped vertical teeth on the rotating disc will drive the third gear to rotate. The rotation of the third gear will cause the clamping plate and the blade to rotate 180°. After the clamping plate and the blade have rotated 180°, the compression force of the torsion spring will cause the other end of the blade to contact the grinding disc to continue grinding the blade, thus completing the function of the automatic face-changing grinding mechanism.

[0045] As a preferred technical solution of the present invention, the clamping structure includes a clamping plate, one end of which is in contact with the grinding shell and the other end is movably connected to the support platform, and a hydraulic cylinder is provided inside the clamping plate.

[0046] Preferably, the clamping piece is a trapezoidal clamping piece.

[0048] Preferably, a second sliding groove is provided in the clamping plate near the hydraulic cylinder, one end of the U-shaped fork near the hydraulic cylinder push rod is slidably connected in the second sliding groove, and the other end of the U-shaped fork away from the hydraulic cylinder push rod is slidably connected in the third sliding groove.

[0049] Preferably, a trapezoidal clamping plate is slidably connected in the third groove, one end of the trapezoidal clamping plate is in contact with the open end of the U-shaped fork, and the other end of the trapezoidal clamping plate is in contact with the blade.

[0050] Preferably, the second groove is a rectangular groove.

[0051] Preferably, the third groove is a rectangular groove.

[0052] As a preferred embodiment of the present invention, the clamping plate is further provided with a rectangular clamping groove, which is installed on one side edge of the clamping plate near the grinding housing and is symmetrically arranged at both ends of the blade.

[0053] Preferably, a fourth sliding groove is provided inside the trapezoidal clamp, and a fixed rectangular plate is slidably connected inside the fourth sliding groove.

[0054] Preferably, a tension spring is fixedly connected to one end of the fixed rectangular plate, and the end of the tension spring away from the fixed rectangular plate is fixedly connected to the trapezoidal clamping plate. Both ends of the connection between the fixed rectangular plate and the tension spring in the vertical direction are fixedly connected to the inner wall of the clamping piece.

[0055] Preferably, the fourth groove is a rectangular groove.

[0056] As a preferred embodiment of the present invention, the bottom of the clamping piece is connected to a supporting protrusion, and the bottom of the supporting protrusion is fixedly connected to the inner wall of the grinding housing.

[0057] It should be noted that the present invention has a support protrusion in contact with the bottom of the clamping plate, and the lower end of the support protrusion is fixedly connected to the grinding housing. This can prevent the clamping plate from hitting the grinding disc and damaging the grinding disc when the clamping plate and the blade return to their original positions, thereby increasing the service life of the grinding disc.

[0058] As a preferred embodiment of the present invention, both the rotary motor and the hydraulic cylinder are wirelessly connected to a remote control device.

[0059] Preferably, the remote control device is a remote controller.

[0060] It should be noted that both the rotary motor and the hydraulic cylinder of this invention are wirelessly connected to a remote control device, meaning that the start and stop of both are controlled by a remote control. This can reduce the user's labor, increase the degree of automation, and speed up the grinding efficiency of the blades.

[0061] As a preferred embodiment of the present invention, a through groove is provided at the connection between the grinding housing and the support platform, a grinding disc is provided in the through groove, and the fourth rotating shaft is fixedly connected to the middle of the grinding disc.

[0062] Preferably, the outer circumferential surface of the grinding disc is provided with teeth for grinding the blades.

[0063] It should be noted that the outer circumferential surface of the grinding disc in this invention is provided with teeth, which can realize the grinding of the blade while the blade is being ground, greatly reducing the grinding steps and increasing the efficiency of grinding the blade.

[0064] Preferably, the grinding structure operates once after the grinding disc rotates three times.

[0065] It should be noted that in this invention, the grinding structure operates once after the grinding disc rotates three times, which ensures the grinding time for each blade tip and increases the sharpness of the blade tip.

[0066] It should be noted that the working principle of the automatic grinding device of the present invention includes:

[0067] The user can remove the blade from the razor and place it into the rectangular clamping slot of the clamping plate. Then, the user can control the hydraulic cylinder via remote control to move the hydraulic cylinder push rod to one end. The movement of the hydraulic cylinder push rod to one end causes the U-shaped fork to move to one end. The movement of the U-shaped fork to one end pushes the symmetrically distributed trapezoidal clamping plates towards the blade and puts the tension spring in a stretched state. The symmetrically distributed trapezoidal clamping plates move towards the blade to clamp the blade, thus completing the blade clamping mechanism function.

[0068] At this point, the blade tip contacts the grinding disc. The user can then use a remote control to turn on the rotary motor, which in turn drives the motor shaft to rotate. The rotating motor shaft drives the rotating worm gear, which in turn drives the rotating turbine, which in turn drives the second shaft to rotate. The second shaft then drives the rotating top plate, the rotating disc, and the first gear to rotate. The first gear then drives the second gear, which in turn drives the grinding disc to rotate. The rotation of the grinding disc grinds the blade.

[0069] Furthermore, the rotation of the top plate and the rotating disk simultaneously drives the convex block and the arc-shaped vertical tooth to rotate. The rotation of the convex block pushes the fixed ball to one end, which in turn drives the rotating lever to rotate. The rotation of the rotating lever drives the fixed lifting lug to one end, which in turn drives the fixed lifting lug to one end. The movement of the fixed lifting lug to one end drives the rectangular slider to one end along the direction of the fixed optical axis. The movement of the rectangular slider to one end along the direction of the fixed optical axis drives the fixed push rod to one end, which in turn drives the fixed cylinder to one end. The movement of one end of the connecting shaft causes one end of the connecting shaft to move. The movement of one end of the connecting shaft causes the third gear and the blade in the clamping plate to be in a flat state and the torsion spring to be in a compressed state. At this time, the blade is separated from the grinding disc and the arc-shaped vertical teeth on the rotating disc will drive the third gear to rotate. The rotation of the third gear will cause the clamping plate and the blade to rotate 180°. After the clamping plate and the blade have rotated 180°, the compression force of the torsion spring will cause the other end of the blade to contact the grinding disc to continue grinding the blade, thus completing the function of the automatic grinding device until the grinding of the entire blade is completed.

[0070] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0071] In this invention, by integrating the support platform, grinding housing, grinding structure, and clamping architecture, automatic blade resurfacing and grinding are achieved. The grinding mechanism can prevent the blade from impacting the structure and causing damage during resurfacing, thus increasing the service life of the structure. Furthermore, the clamping structure in this invention can be applied to grinding blades of different thicknesses, enhancing its practicality. The overall structure is simple, easy to operate, and suitable for widespread use. Attached Figure Description

It should be noted that the torsion spring 40 in this invention is a high-strength torsion spring, which can realize the return of the clamping plate 5 and the blade 4, which is beneficial to completing the function of the automatic face-changing grinding mechanism.

[0093] It should be noted that the working principle of the grinding structure in this invention includes:

[0094] The user can activate the rotary motor 8 via remote control to rotate the electrode shaft. The rotation of the electrode shaft drives the rotary worm gear 11, which in turn drives the rotary turbine 13. The rotary turbine 13 then drives the second shaft 14, which in turn drives the rotary top plate 23, the rotary disc 15, and the first gear 17. The first gear 17 then drives the second gear 18, which in turn drives the grinding disc 3. The grinding disc 3 grinds the blade 4. Simultaneously, the rotation of the rotary top plate 23 and the rotary disc 15 drives the arc-shaped protrusion 24 and the arc-shaped vertical tooth 16. The arc-shaped protrusion 24 pushes the fixed ball 22 to one end, which in turn rotates the rotary lever 21. The rotation of the rotary lever 21 then moves the fixed lifting lug 35 to one end, which in turn moves the fixed lifting lug 36 to one end. The movement of 6 to one end causes the rectangular slider 37 to move along one end of the fixed optical axis 38. The movement of the rectangular slider 7 along the fixed optical axis 38 causes the fixed push rod 29 to move to one end. The movement of the fixed push rod 29 to one end causes the fixed cylinder 28 to move to one end. The movement of the fixed cylinder 28 to one end causes the connecting shaft 26 to move to one end. The movement of the connecting shaft 26 to one end causes the third gear 27 and the blade 4 in the clamping plate 5 to be in a flat state and the torsion spring 40 to be in a compressed state. At this time, the blade 4 is separated from the grinding disc 3, and the arc-shaped vertical teeth 16 on the rotating disc 15 will drive the third gear 27 to rotate. The rotation of the third gear 27 will drive the clamping plate 5 and the blade 4 to rotate 180°. After the clamping plate 5 and the blade 4 have rotated 180°, the compression force of the torsion spring 40 will cause the other end of the blade 4 to contact the grinding disc 3 to continue grinding the blade 4, thus completing the function of the automatic face-changing grinding mechanism.

[0095] The clamping structure includes a clamping plate 5. One end of the clamping plate 5 contacts and connects to the grinding housing 2, and an irregular notch 34 is provided on the side near the grinding housing 2. The other end is movably connected to the support platform 1. A hydraulic cylinder 31 is provided inside the clamping plate 5. The clamping plate 5 is a trapezoidal clamping plate. A hydraulic cylinder push rod 32 is movably connected to the end of the hydraulic cylinder 31 away from the support platform 1. The end of the hydraulic cylinder push rod 32 away from the hydraulic cylinder 31 is fixedly connected to the closed end of the U-shaped fork 41. A second sliding groove 39 is provided inside the clamping plate 5 near the hydraulic cylinder 31. The end of the U-shaped fork 41 near the hydraulic cylinder push rod 32 is slidably connected to the second sliding groove 39. The end of the U-shaped fork 41 away from the hydraulic cylinder push rod 32 is slidably connected to the third sliding groove 42. A trapezoidal clamping plate 43 is slidably connected in the third sliding groove 42. One end of the trapezoidal clamping plate 43 contacts and connects to the open end of the U-shaped fork 41, and the other end of the trapezoidal clamping plate 43 contacts and connects to the blade 4. Furthermore, the second slide 39 is a rectangular slide, and the third slide 42 is a rectangular slide.

[0096] The clamping plate 5 is also provided with a rectangular clamping groove 44. The rectangular clamping groove 44 is installed on the side edge of the clamping plate 5 near the grinding housing 2 and is symmetrically arranged at both ends of the blade 4. The trapezoidal clamping plate 43 is provided with a fourth sliding groove 46. A fixed rectangular plate 47 is slidably connected in the fourth sliding groove 46. A tension spring 45 is fixedly connected to one end of the fixed rectangular plate 47. The end of the tension spring 45 away from the fixed rectangular plate 47 is fixedly connected to the trapezoidal clamping plate 43. Both ends of the fixed rectangular plate 47 and the tension spring 45 in the vertical direction are fixedly connected to the inner wall of the clamping plate 5. Furthermore, the fourth sliding groove 46 is a rectangular sliding groove.

[0097] The bottom of the clamping piece 5 is connected to a support protrusion 25, and the bottom of the support protrusion 25 is fixedly connected to the inner wall of the grinding housing 2. It should be noted that the support protrusion 25 connected to the bottom of the clamping piece 5 and the lower end of the support protrusion 25 fixedly connected to the grinding housing 2 can prevent the clamping piece 5 from impacting the grinding disk 3 and damaging the grinding disk 3 when the clamping piece 5 and the blade 4 return to their original positions, thereby increasing the service life of the grinding disk 3.

[0098] Both the rotary motor 8 and the hydraulic cylinder 31 are wirelessly connected to a remote control device, which is a remote controller. It should be noted that the fact that both the rotary motor 8 and the hydraulic cylinder 31 are wirelessly connected to a remote control device means that their start and stop are controlled by a remote controller, which can reduce the user's labor, increase the degree of automation, and speed up the grinding efficiency of the blade 4.

[0099] A through groove 49 is provided at the connection between the grinding housing 2 and the support platform 1. A grinding disc 3 is disposed within the through groove 49. A fourth rotating shaft 19 is fixedly connected to the center of the grinding disc 3. The outer circumferential surface of the grinding disc 3 is provided with teeth for grinding the blade 4. It should be noted that the teeth on the outer circumferential surface of the grinding disc 3 in this invention enable grinding of the blade 4 simultaneously with changing the grinding surface, greatly reducing the grinding steps and increasing the efficiency of grinding the blade 4.

[0100] After the grinding disc 3 rotates three times, the grinding structure operates once. It should be noted that in this invention, the grinding structure operates once after the grinding disc 3 rotates three times, which ensures the grinding time for each tip of the blade 4 and increases the sharpness of the blade tip.

[0101] It should be noted that the working principle of the automatic grinding device of the present invention includes:

[0102] The user can remove the blade 4 from the razor and place it into the rectangular clamping slot 44 of the clamping plate 5. Then, the user can control the hydraulic cylinder 31 via remote control to move the hydraulic cylinder push rod 32 to one end. The movement of the hydraulic cylinder push rod 32 to one end causes the U-shaped fork 41 to move to one end. The movement of the U-shaped fork 41 to one end pushes the symmetrically distributed trapezoidal clamping plates 43 towards the blade 4 and puts the tension spring 45 in a stretched state. The symmetrically distributed trapezoidal clamping plates 43 move towards the blade 4 to clamp the blade 4, thus completing the blade clamping mechanism function.

[0103] At this time, the tip of the blade 4 contacts the grinding disc 3. Then, the user can turn on the rotary motor 8 via remote control, which drives the motor shaft 9 to rotate. The rotation of the motor shaft 9 drives the rotary worm gear 11 to rotate, which in turn drives the rotary turbine 13 to rotate. The rotation of the rotary turbine 13 drives the second shaft 14 to rotate, which in turn drives the rotary top plate 23, the rotary disc 15, and the first gear 17 to rotate. The rotation of the first gear 17 drives the second gear 18 to rotate, which in turn drives the grinding disc 3 to rotate. The rotation of the grinding disc 3 can grind the blade 4. The rotation of the rotary top plate 23 and the rotary disc 15 simultaneously drives the protrusion and the arc-shaped vertical tooth 16 to rotate. The rotation of the protrusion pushes the fixed ball 22 to move to one end. The movement of the fixed ball 22 to one end drives the rotary lever 21 to rotate. The rotation of the rotary lever 21 drives the fixed lifting lug 35 to move to one end, which in turn drives the fixed lifting lug 36 to move to one end. The movement of 36 to one end causes the rectangular slider 37 to move along one end of the fixed optical axis 38. The movement of the rectangular slider 37 along the fixed optical axis 38 causes the fixed push rod 29 to move to one end. The movement of the fixed push rod 29 to one end causes the fixed cylinder 28 to move to one end. The movement of the fixed cylinder 28 to one end causes the connecting shaft 26 to move to one end. The movement of the connecting shaft 26 to one end causes the third gear 27 and the blade 4 in the clamping plate 5 to be in a flat state and the torsion spring 40 to be in a compressed state. At this time, the blade 4 is separated from the grinding disc 3 and the arc-shaped vertical teeth 16 on the rotating disc 15 will drive the third gear 27 to rotate. The rotation of the third gear 27 will drive the clamping plate 5 and the blade 4 to rotate 180°. After the clamping plate 5 and the blade 4 have rotated 180°, the compression force of the torsion spring 40 will cause the other end of the blade 4 to contact the grinding disc 3 to continue grinding the blade 4, thus completing the function of the automatic grinding device until the grinding of the entire blade 4 is completed.

[0104] In summary, this invention integrates the support platform 1, grinding housing 2, grinding structure, and clamping architecture into a single unit, achieving automatic blade resurfacing and grinding. The grinding mechanism prevents the blade 4 from impacting the structure and causing damage during resurfacing, thus increasing the structure's lifespan. Furthermore, the clamping structure in this invention is suitable for grinding blades 4 of different thicknesses, enhancing its practicality. The overall structure is simple, easy to operate, and suitable for widespread use. This invention is particularly suitable for grinding shaving blades.

Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention fall within the protection and disclosure scope of the present invention.
