Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, specifically a ceramic knife grinding and single-sided sharpening device with multi-directional grinding function. Background Technology

[0002] In ceramic production, the slitting and chipping of green ceramic rolls affects the surface quality of the green body. Therefore, ultrasonic slitting is used to cut the green rolls, and the key to the cutting effect lies in the quality of the blade edge. Currently, ceramic blade grinding machines on the market can only grind single blades, not multiple blades at once, resulting in slow batch processing efficiency. Furthermore, most ceramic blade grinding machines on the market use manual feeding, which cannot guarantee consistent processing angles, leading to inconsistent sharpening effects and affecting the stability of processing quality. Processing efficiency also gradually decreases due to worker fatigue. Therefore, we need a ceramic blade grinding single-sided sharpening device with multi-directional grinding capabilities to improve the surface quality of ceramic blade edges and increase production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a ceramic knife grinding and single-sided sharpening device with multi-directional grinding function to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The sharpening device includes a housing, a feeding unit, a grinding unit, a fixed base, a rotating motor, a first gear, a transmission gear, an external gear, a freewheel, a central gear, and a clamping fixture. The feeding unit is located inside the housing, the grinding unit is located inside the housing, the fixed base is located inside the housing, the rotating motor is located inside one end of the fixed base, and the rotating motor and the fixed base are fixedly connected. The first gear and the output shaft of the rotating motor are fixedly connected. The transmission gear is located inside the fixed base and is rotatably connected to the fixed base. The first gear and the transmission gear mesh, the transmission gear and the external gear mesh, the external gear and the fixed base are rotatably connected, the central gear and the grinding unit are fixedly connected, the central axis of the central gear coincides with the central axis of the external gear, and the central gear passes through the external gear. The freewheel is located between the external gear and the central gear and meshes with both the external gear and the central gear. The fixed base has a through hole with the same central axis as the external gear, and the radius of the through hole on the fixed base is smaller than the radius of the through hole of the external gear. The external gear is located within the grinding range of the grinding unit.

[0006] The front panel of the outer casing is made of transparent plastic, making it easy to observe the grinding status of the blade. The feeding unit is responsible for sending the blade to the clamping fixture for clamping and fixing. The clamping fixture holds the blade at a preset fixed angle. The rotating motor starts, driving the external gear to rotate through the transmission gear. The grinding unit drives the central gear to rotate. The central gear and the external gear rotate in opposite directions. The freewheel meshes with the central gear and the external gear to form a planetary gear system. The grinding is performed by contact grinding in a planetary rotation and revolution mode, providing multi-directional grinding, which makes the surface quality of the ceramic cutting edge better and the cutting edge sharper. After the grinding unit finishes grinding one end face of the blade, the clamping fixture is adjusted to fix the blade at another preset angle, and then the other end face of the blade is ground. After grinding is completed, the rotating motor and the grinding unit stop working, the clamping fixture returns to the initial angle, the blade is released, the feeding unit takes out the blade, and sends it to the laser cutting area for scribing and cutting.

[0007] Furthermore, the feeding unit includes a rotating chassis, a feeding cylinder, a feeding column, grippers, and a feeding slider. The rotating chassis is located inside the outer casing. The feeding column is fixedly connected to the upper end face of the rotating chassis, and the central axis of the feeding column and the rotating chassis coincides. The bottom end of the feeding cylinder is fixedly connected to the upper end face of the rotating chassis. The push rod end of the feeding cylinder is fixedly connected to the feeding slider. The feeding slider is slidably connected to the feeding column. Multiple grippers are provided at the end of the feeding slider away from the feeding column.

[0008] The gripper layout allows the blade to be placed in the initial clamping fixture. When ready for grinding, the feeding unit operates, the grippers first pick up the blade, the rotating base rotates, aligning the grippers with the clamping fixture, the feeding cylinder descends, the grippers release the blade, and the blade is placed into the clamping fixture. The feeding cylinder rises, the rotating base rotates, and the grippers return to their original position. When grinding is finished, the clamping fixture returns to its original position and releases the blade. The feeding unit operates again, the rotating base rotates, aligning the grippers with the clamping fixture, the feeding cylinder descends, the grippers pick up the blade, the feeding cylinder rises, the rotating base rotates, and the ground blade is sent to the next stage.

[0009] Furthermore, the grinding unit includes a grinding column, an upper grinding cylinder, an upper grinding slider, an upper grinding motor, an upper grinding disc, a lower grinding cylinder, a lower grinding slider, a lower grinding motor, and a lower grinding disc. The grinding column is disposed within the outer casing and is fixedly connected to the outer casing. The upper grinding cylinder is fixedly connected to the upper end of the grinding column. The push rod end of the upper grinding cylinder is fixedly connected to the upper grinding slider. The upper grinding slider is slidably connected to the grinding column. The upper grinding motor is disposed at the end of the upper grinding slider away from the grinding column and is fixedly connected to the upper grinding slider. The output shaft of the upper grinding disc is fixedly connected to the upper grinding disc, the grinding surface of the upper grinding disc is parallel to the clamping fixture, the lower grinding cylinder is fixedly connected to the lower end of the grinding column, the push rod end of the lower grinding cylinder is fixedly connected to the lower grinding slider, the lower grinding slider is slidably connected to the grinding column, the lower grinding motor is located at the end of the lower grinding slider away from the grinding column, the lower grinding motor is fixedly connected to the lower grinding slider, the output shaft of the lower grinding motor is fixedly connected to the lower grinding disc, the grinding surface of the lower grinding disc is parallel to the clamping fixture, and the central axes of the upper grinding disc, the lower grinding disc, and the central gear coincide.

[0010] After the clamping fixture holds the blade, the lower grinding motor and the rotary motor start. The lower grinding disc drives the central gear to rotate, accelerating the planetary gear motion composed of the central gear, the freewheel, and the external gear, thus improving grinding efficiency. The lower grinding cylinder gradually pushes the lower grinding slider upward, allowing the lower grinding disc to grind and sharpen one side of the blade's lower end. After grinding one side of the blade's lower end, the lower grinding cylinder pulls the lower grinding slider downward, stopping the grinding of one side of the blade's lower end. The clamping fixture is adjusted to fix the blade at another preset angle, and grinding is then performed on one side of the blade's upper end. The upper grinding motor starts, and the upper grinding cylinder gradually pushes the upper grinding slider downward, allowing the upper grinding disc to grind and sharpen one side of the blade's upper end. After grinding is completed, the upper grinding cylinder pulls the upper grinding slider upward, and the lower grinding motor and the rotary motor rotate the clamping fixture back to its original position before stopping the operation.

[0011] Furthermore, the upper grinding disc includes an upper grinding disc body, an upper grinding disc spring, and an upper grinding disc plate. A hole is provided on the grinding surface of the upper grinding disc body, and the hole on the grinding surface of the upper grinding disc body coincides with the central axis of the upper grinding disc body. The upper grinding disc spring is disposed in the hole on the grinding surface of the upper grinding disc body. One end of the upper grinding disc spring is fixedly connected to the upper grinding disc body, and the other end of the upper grinding disc spring is fixedly connected to the upper grinding disc plate. The upper grinding disc plate and the upper grinding disc body are slidably connected.

[0012] When the upper grinding disc body grinds the upper end of the blade, it gradually approaches the central gear. The central gear abuts against the upper grinding disc plate. At this time, the upper grinding disc spring is pressed down, allowing the upper grinding disc body to continue to descend and grind the blade completely.

[0013] Furthermore, the lower grinding disc includes a lower grinding disc body, a lower grinding disc spring, and a lower grinding disc plate. A hole is provided on the grinding surface of the lower grinding disc body, and the hole on the grinding surface of the lower grinding disc body coincides with the central axis of the lower grinding disc body. The lower grinding disc spring is disposed in the hole on the grinding surface of the lower grinding disc body. One end of the lower grinding disc spring is fixedly connected to the lower grinding disc body, and the other end of the lower grinding disc spring is fixedly connected to the lower grinding disc plate. The lower grinding disc plate and the lower grinding disc body are slidably connected, and the lower grinding disc plate is fixedly connected to the central gear.

[0014] Because the central gear and the walking wheel mesh, the central gear will not move as the lower grinding disc body moves closer to the blade during high-speed rotation. The central gear presses against the lower grinding disc plate, at which point the lower grinding disc spring is pressed down, allowing the lower grinding disc body to continue to rise and perform complete grinding on the blade.

[0015] Furthermore, the clamping fixture includes a clamping seat, stainless steel positioning scales, a clamping cylinder, a clamping motor, a stop bar, and a connecting rod. The clamping seat and the freewheel are fixedly connected. Multiple stainless steel positioning scales are arrayed between the clamping seats, with gaps between them. The stainless steel positioning scales pass through the clamping seats and are rotatably connected to them. The connecting rod is rotatably connected to the stainless steel positioning scales. Both ends of the stop bar are rotatably connected to the clamping seat. The clamping motor is fixedly connected to the clamping seat. The output shaft of the clamping motor is fixedly connected to the stop bar. The central axis of the output shaft of the clamping motor and the rotation axis of the stop bar coincide. The direction of the stop bar and the array of stainless steel positioning scales is parallel. The clamping cylinder is fixedly connected to the clamping seat. The push rod end of the clamping cylinder is fixedly connected to the stainless steel positioning scales. The direction of the push rod of the clamping cylinder and the array of stainless steel positioning scales is parallel.

[0016] The initial position of the stop bar prevents all blades from falling through the gaps in the stainless steel positioning scales. When the feeding unit delivers the blades to the clamping fixture, the blades fall from the gaps in the stainless steel positioning scales onto the stop bar, ensuring that the bottom ends of all blades are on the same horizontal plane. The clamping cylinder pushes the stainless steel positioning scales, causing them to tilt and clamp the blades. The clamping motor starts, rotating the stop bar to both sides of the clamping seat. Then, the lower grinding disc grinds the blades. After grinding, the clamping motor starts, rotating the stop bar back to its original position. The clamping cylinder pulls the stainless steel positioning scales, causing them to tilt and clamp the blades. The clamping motor starts, rotating the stop bar to both sides of the clamping seat. Then, the upper grinding disc grinds the blades. After grinding, the clamping motor starts, rotating the stop bar back to its original position. The clamping cylinder resets and stops working, returning the stainless steel positioning scales to their original position and releasing the blades, ready for clamping and conveying by the feeding unit.

[0017] Furthermore, the clamping base has through holes at both ends.

[0018] Furthermore, the spiral wheel is equipped with through holes.

[0019] The through holes on the clamping seat and the spiral wheel facilitate the positioning and installation of the clamping seat on the spiral wheel.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The present invention uses planetary gear rotation and revolution to perform contact grinding, which can perform grinding in multiple directions, resulting in better surface quality of ceramic cutting edge and sharper cutting edge;

[0022] 2. This invention uses stainless steel positioning scales to hold the blades, which can process a large number of ceramic blades. The blades are placed at the same angle and clamped and fixed, ensuring the stability of processing quality and improving production efficiency.

[0023] 3. The feeding unit and clamping fixture of the present invention work together to eliminate the need for manual feeding, thereby achieving equipment automation, reducing labor costs, and improving processing efficiency;

[0024] 4. This invention allows for single-sided sharpening of both ends of the blade without removing and reinstalling it. Simply by adjusting the clamping fixture, single-sided sharpening of both ends of the blade can be performed, which improves sharpening efficiency and reduces time costs. Attached Figure Description

[0035] Example: Figure 1 - Figure 8 As shown, this invention provides a technical solution for a ceramic knife grinding and single-sided sharpening device with multi-directional grinding function:

[0036] like Figure 1 , Figure 2 and Figure 6As shown, the sharpening device includes a housing 1, a feeding unit 2, a grinding unit 3, a fixed base 4, a rotating motor 5, a first gear 6, a transmission gear 7, an external gear 8, a freewheel 9, a central gear 10, and a clamping fixture 11.

[0037] The front panel of the outer casing 1 is a transparent plastic plate, which makes it easy to observe the grinding status of the blade. The feeding unit 2 is responsible for feeding the blade to the clamping fixture 11 for clamping and fixing. The clamping fixture 11 clamps and fixes the blade at a preset fixed angle. The rotating motor 5 starts, and drives the external gear 8 to rotate through the transmission gear 7. The grinding unit 3 drives the central gear 10 to rotate. The central gear 10 and the external gear 8 rotate in opposite directions. The centroid wheel 9 meshes with the central gear 10 and the external gear 8 to form a planetary gear system. The planetary gears rotate and revolve to perform contact grinding, providing multi-directional grinding, which makes the surface quality of the ceramic cutting edge better and the cutting edge sharper. After the grinding unit 3 finishes grinding one end face of the blade, it adjusts the clamping fixture 11 to fix the blade at another preset angle and then grinds the other end face of the blade. After the grinding is completed, the rotating motor 5 and the grinding unit 3 stop working, the clamping fixture 11 returns to the initial angle, the blade is released, the feeding unit 2 takes out the blade and sends it to the laser cutting area for scribing and cutting.

[0038] like Figure 1 and Figure 8As shown, the feeding unit 2 includes a rotating base 21, a feeding cylinder 22, a feeding column 23, grippers 24, and a feeding slider 25. The rotating base 21 is disposed inside the outer casing 1. The feeding column 23 is fixedly connected to the upper end face of the rotating base 21. The central axis of the feeding column 23 and the rotating base 21 coincides. The bottom end of the feeding cylinder 22 is fixedly connected to the upper end face of the rotating base 21. The push rod end of the feeding cylinder 22 is fixedly connected to the feeding slider 25. The feeding slider 25 is slidably connected to the feeding column 23. Multiple grippers 24 are provided at the end of the feeding slider 25 away from the feeding column 23.

[0039] The arrangement of the gripper 24 allows the blade to be placed in the clamping fixture 11 in its initial state. When preparing for grinding, the feeding unit 2 operates, the gripper 24 first picks up the blade, the rotating base 21 rotates, aligning the gripper 24 with the clamping fixture 11, the feeding cylinder 22 descends, the gripper 24 releases the blade, and the blade is placed into the clamping fixture 11. The feeding cylinder 22 rises, the rotating base 21 rotates, and the gripper 24 returns to its original position. When grinding is finished, the clamping fixture 11 returns to its original position and releases the blade. The feeding unit 2 operates, the rotating base 21 rotates, aligning the gripper 24 with the clamping fixture 11, the feeding cylinder 22 descends, the gripper 24 picks up the blade, the feeding cylinder 22 rises, the rotating base 21 rotates, and the ground blade is sent to the next stage.

[0040] like Figures 3-5 As shown, the grinding unit 3 includes a grinding column 31, an upper grinding cylinder 32, an upper grinding slider 33, an upper grinding motor 34, an upper grinding disc 35, a lower grinding cylinder 36, a lower grinding slider 37, a lower grinding motor 38, and a lower grinding disc 39. The grinding column 31 is disposed inside the outer casing 1 and is fixedly connected to the outer casing 1. The upper grinding cylinder 32 is fixedly connected to the upper end of the grinding column 31. The push rod end of the upper grinding cylinder 32 is fixedly connected to the upper grinding slider 33. The upper grinding slider 33 is slidably connected to the grinding column 31. The upper grinding motor 34 is disposed at the end of the upper grinding slider 33 away from the grinding column 31 and is fixedly connected to the upper grinding slider 33. The output shaft of 34 is fixedly connected to the upper grinding disc 35. The grinding surface of the upper grinding disc 35 is parallel to the clamping fixture 11. The lower grinding cylinder 36 is fixedly connected to the lower end of the grinding column 31. The push rod end of the lower grinding cylinder 36 is fixedly connected to the lower grinding slider 37. The lower grinding slider 37 is slidably connected to the grinding column 31. The lower grinding motor 38 is located at the end of the lower grinding slider 37 away from the grinding column 31. The lower grinding motor 38 is fixedly connected to the lower grinding slider 37. The output shaft of the lower grinding motor 38 is fixedly connected to the lower grinding disc 39. The grinding surface of the lower grinding disc 39 is parallel to the clamping fixture 11. The central axes of the upper grinding disc 35, the lower grinding disc 39, and the central gear 10 coincide.

[0041] After the clamping fixture 11 clamps the blade, the lower grinding motor 38 and the rotary motor 5 start. The lower grinding disc 39 drives the central gear 10 to rotate, accelerating the planetary gear motion composed of the central gear 10, the freewheel 9, and the external gear 8, thereby improving grinding efficiency. The lower grinding cylinder 36 gradually pushes the lower grinding slider 37 upward, allowing the lower grinding disc 39 to grind and sharpen one side of the lower end of the blade. After the grinding of one side of the lower end of the blade is completed, the lower grinding cylinder 36 pulls the lower grinding slider 37 downward, stopping the grinding of one side of the lower end of the blade. The clamping fixture 11 is adjusted to fix the blade at another preset angle, and the upper side of the blade is ground. The upper grinding motor 34 starts, and the upper grinding cylinder 32 gradually pushes the upper grinding slider 33 downward. The upper grinding disc 35 grinds and sharpens one side of the upper end of the blade. After the grinding is completed, the upper grinding cylinder 32 pulls the upper grinding slider 33 upward, and the lower grinding motor 38 and the rotary motor 5 rotate the clamping fixture 11 back to its original position and then stop working.

[0042] like Figure 4 As shown, the upper grinding disc 35 includes an upper grinding disc body 351, an upper grinding disc spring 352, and an upper grinding disc plate 353. A hole is provided on the grinding surface of the upper grinding disc body 351, and the hole on the grinding surface of the upper grinding disc body 351 coincides with the central axis of the upper grinding disc body 351. The upper grinding disc spring 352 is disposed in the hole on the grinding surface of the upper grinding disc body 351. One end of the upper grinding disc spring 352 is fixedly connected to the upper grinding disc body 351, and the other end of the upper grinding disc spring 352 is fixedly connected to the upper grinding disc plate 353. The upper grinding disc plate 353 and the upper grinding disc body 351 are slidably connected.

[0043] When the upper grinding disc body 351 grinds the upper end of the blade, it gradually approaches the central gear 10. The central gear 10 abuts against the upper grinding disc plate 353. At this time, the upper grinding disc spring 352 is pressed down, so that the upper grinding disc body 351 can continue to descend and grind the blade completely.

[0044] like Figure 5 As shown, the lower grinding disc 39 includes a lower grinding disc body 391, a lower grinding disc spring 392, and a lower grinding disc plate 393. A hole is provided on the grinding surface of the lower grinding disc body 391, and the hole on the grinding surface of the lower grinding disc body 391 coincides with the central axis of the lower grinding disc body 391. The lower grinding disc spring 392 is disposed within the hole on the grinding surface of the lower grinding disc body 391. One end of the lower grinding disc spring 392 is fixedly connected to the lower grinding disc body 391, and the other end of the lower grinding disc spring 392 is fixedly connected to the lower grinding disc plate 393. The lower grinding disc plate 393 and the lower grinding disc body 391 are slidably connected, and the lower grinding disc plate 393 is fixedly connected to the central gear 10.

[0045] Because the central gear 10 and the rotor 9 mesh, the central gear 10 will not move as the lower grinding disc body 391 moves closer to the blade during high-speed rotation. The central gear 10 presses against the lower grinding disc plate 393, at which point the lower grinding disc spring 392 is pressed down, allowing the lower grinding disc body 391 to continue to rise and perform complete grinding on the blade.

[0046] like Figure 7 As shown, the clamping fixture 11 includes a clamping base 111, stainless steel positioning scales 112, a clamping cylinder 113, a clamping motor 114, a stop bar 115, and a connecting rod 116. The clamping base 111 is fixedly connected to the swing wheel 9. Multiple stainless steel positioning scales 112 are arrayed between the clamping bases 111, with gaps between them. The stainless steel positioning scales 112 pass through the clamping base 111 and are rotatably connected to it. The connecting rod 116 is rotatably connected to the stainless steel positioning scales 112. The stop bar 115... The two ends of 5 are rotatably connected to the clamping seat 111. The clamping motor 114 is fixedly connected to the clamping seat 111. The output shaft of the clamping motor 114 is fixedly connected to the stop bar 115. The central axis of the output shaft of the clamping motor 114 and the rotation axis of the stop bar 115 coincide. The direction of the stop bar 115 and the stainless steel positioning scale 112 array is parallel. The clamping cylinder 113 is fixedly connected to the clamping seat 111. The push rod end of the clamping cylinder 113 is fixedly connected to the stainless steel positioning scale 112. The direction of the push rod of the clamping cylinder 113 and the stainless steel positioning scale 112 array is parallel.

[0047] The initial position of the stop bar 115 prevents all blades from falling through the gaps in the stainless steel positioning scales 112. When the feeding unit 2 delivers the blades to the clamping fixture 11, the blades fall from the gaps in the stainless steel positioning scales 112 onto the stop bar 115. The bottom ends of all blades are on the same horizontal plane. The clamping cylinder 113 pushes the stainless steel positioning scales 112, causing them to tilt and clamp the blades. The clamping motor 114 starts, rotating the stop bar 115 to both sides of the clamping seat 111. Then, the lower grinding disc 39 grinds the blades. After grinding... After completion, the clamping motor 114 starts, rotating the stop bar 115 to its original position. The clamping cylinder 113 pulls the stainless steel positioning scale 112, causing the stainless steel positioning scale 112 to tilt and clamp the blade. The clamping motor 114 starts, rotating the stop bar 115 to both sides of the clamping seat 111. Then, the upper grinding disc 35 grinds the blade. After grinding is completed, the clamping motor 114 starts, rotating the stop bar 115 to its original position. The clamping cylinder 113 resets and stops working, returning the stainless steel positioning scale 112 to its original position and releasing the blade, waiting for the clamping and conveying of the feeding unit 2.

[0048] like Figure 7 As shown, the clamping base 111 has through holes at both ends.

[0049] like Figure 2 As shown, the spiral wheel 9 has a through hole.

[0050] The through holes on the clamping seat 111 and the spindle 9 facilitate the positioning and installation of the clamping seat 111 on the spindle 9.

[0051] The working principle of this invention is as follows: When the sharpening device is ready to operate, the gripper 24 picks up the blade, the rotating base 21 rotates, aligning the blade with the gap of the stainless steel positioning scale 112, the feeding cylinder 22 descends, the gripper 24 releases the blade, and the blade is placed into the gap of the stainless steel positioning scale 112. The clamping cylinder 113 pushes the stainless steel positioning scale 112, causing the stainless steel positioning scale 112 to tilt and clamp the blade. The clamping motor 114 starts, rotating the stop bar 115 to both sides of the clamping seat 111. The rotating motor 5 and the lower grinding motor 38 are started, and the lower grinding cylinder 36 gradually pushes the lower grinding slider 37 upward, allowing the lower grinding disc 39 to grind and sharpen one side of the lower end of the blade.
