Description

Technical Field

[0001] This invention relates to the field of sword production and processing technology, and more specifically, to a sword polishing equipment and polishing method. Background Technology

[0002] A sword is a weapon. It has a double-edged, straight blade with a pointed tip, capable of injuring people horizontally or vertically, and can pierce armor with a thrust. Among them, a fine sword is a sword forged with high-quality materials and unique casting methods. In modern times, fine swords are mostly collectibles or gifts, and people take pride in owning a fine sword.

[0003] After the sword blank is formed, it needs to be polished to bring out its elegance and brilliance. The polishing process generates a large amount of metal shavings and dust. The flying metal shavings can injure workers, and the dust can damage their respiratory system if inhaled. Therefore, it is necessary to collect the metal shavings and dust generated during the polishing process. However, the metal shavings and dust are mixed together during collection, and the presence of dust can hinder the recycling of the metal shavings. Therefore, a separation process is needed to separate the metal shavings and dust. Summary of the Invention

[0013] The present invention is further configured such that: the polishing mechanism includes a polishing seat connected to the lifting seat, a polishing motor is fixedly provided on the front side of the polishing seat, and a polishing disc is driven and connected to the front side of the polishing motor.

[0014] The present invention is further configured such that the polishing method of the sword polishing equipment includes the following steps:

[0015] S1. Open the cover of the polishing chamber, place the sword to be polished into the chamber, clamp the hilt with the clamping mechanism, and then close the cover. S2. The lifting mechanism drives the polishing mechanism to move up and down to polish the sword. S3. After polishing one side of the sword, the clamping mechanism flips the sword over, and the lifting and polishing mechanisms repeat to polish the other side. S4. After polishing both sides, the clamping mechanism rotates the sword back to its initial position, then releases the sword and removes the polished sword. S5. During the polishing process, the drive unit is activated to control the drive shaft to rotate, thereby rotating the suction roller. The suction pipes in the first, second, and third air slots are connected to an external power source to draw in the first air... The gases in the first, second, and third air slots connect the air supply pipe in the fourth air slot to an external power source to deliver external air into the suction roller through the fourth air slot; S6, the suction roller rotates, causing each separation chamber to sequentially pass through the first, second, third, and fourth air slots. When passing through the first air slot, since the position of the first air slot corresponds to the position of the third channel, and the support platform is fixedly located on the corresponding side of the first air slot with a dust collection chamber, the suction roller draws metal debris and dust particles generated by grinding in the grinding box from the dust collection chamber into the corresponding separation chamber through the suction hole; S7, the separation chamber is sequentially equipped with a first filter and a second filter from the outside to the inside. The first filter blocks metal debris in the air and retains it in the first channel. The second filter blocks airborne dust and retains it in the second channel, while clean air enters the third channel and is discharged from the first air groove to the outside of the suction roller; S8, the drive unit drives the suction roller to continue rotating and passing through the second and third air grooves. When passing through the second air groove, the dust in the second channel is drawn and collected, and when passing through the third air groove, the metal debris in the first channel is drawn and collected; S9, the drive unit drives the suction roller to continue rotating and passing through the fourth air groove. The fourth air groove is connected to the third channel and sealed with an air supply pipe. The air supply pipe is connected to an external power source to send external gas into the fourth air groove and into the suction roller. A dust return chamber is fixed on the support platform on the side corresponding to the fourth air groove. The dust return chamber has a dust return port and the suction roller... The pressure plate contacts and seals the dust return port. The rotation of the dust collection roller causes one of the separation chambers to align with the fourth air groove. At this time, the separation chamber has passed through the first air groove, the second air groove, and the third air groove, and completed the separation and collection of dust and metal fragments. The position of the fourth air groove corresponds to the third channel. An external air pump introduces gas from the fourth air groove into the third channel. The gas passes through the second channel and the first channel from the third channel and is discharged to the dust collection roller through the suction hole. The gas discharged from the suction hole enters the dust return chamber for collection. S10, the first main pipe, and the second main pipe are all connected to a power source to send the dust and metal particles in the dust return chamber back to the dust collection chamber, and then back to the dust collection roller for secondary separation of the gas in the dust return chamber.

[0016] In summary, the present invention has the following beneficial effects: the hilt of the sword is clamped by the clamping mechanism, and then the polishing mechanism is started. The lifting mechanism drives the polishing machine mechanism to move up and down and polish one side of the sword. After one side of the sword is polished, the polishing mechanism returns to its original position. At this time, the clamping mechanism drives the hilt and the sword blank to turn over. Then the polishing mechanism and the lifting mechanism repeat the above operation to polish the other side of the sword. During the polishing process, dust and metal shavings are generated and fly into the box. The dust collection mechanism is used to collect the metal shavings and dust generated during the polishing of the box, so as to avoid the metal shavings flying and injuring the staff, and the dust being inhaled by the staff and causing damage to the respiratory system. The dust collection mechanism can further separate and collect the dust and metal shavings for subsequent recycling of the metal shavings. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0030] Please see Figure 1-10As shown, an embodiment of the present invention provides a sword polishing device, including a polishing box 1. The top of the polishing box 1 has an opening, and a clamping mechanism 2 is provided at the bottom of the inner wall. The clamping mechanism 2 is used to clamp the sword and drive the sword to rotate and flip. A polishing mechanism is provided on one side of the inner wall of the polishing box 1, and the polishing mechanism is connected to a lifting mechanism. The lifting mechanism is used to control the polishing mechanism to move radially up and down to polish the sword blank. A support table 5 is provided on one side of the polishing box 1, and a dust collection mechanism 500 is provided on the support table 5. The dust collection mechanism 500 picks up the metal debris and dust generated by the operation of the polishing box 1 and separates and collects the metal debris and dust.

[0031] In use, the sword to be polished is placed into the polishing box 1 through the opening at the top of the box (the opening is hinged to a box cover). The hilt of the sword is clamped by the clamping mechanism 2. Then, the polishing mechanism is started. The lifting mechanism drives the polishing machine mechanism to move up and down and polish one side of the sword. After one side of the sword is polished, the polishing mechanism returns to its original position. At this time, the clamping mechanism 2 drives the hilt and the sword blank to turn over. Then, the polishing mechanism and the lifting mechanism repeat the above operation to polish the other side of the sword. During the polishing process, dust and metal shavings are generated and fly into the box. The dust collection mechanism 500 is used to collect the metal shavings and dust generated by the polishing box 1 to prevent metal shavings from flying and injuring the staff, and to prevent the staff from inhaling the dust and causing damage to the respiratory system. The dust collection mechanism 500 can further separate and collect the dust and metal shavings for subsequent recycling of the metal shavings.

[0032] The vacuuming mechanism 500 includes a vacuuming roller 501 and a suction chamber 502 is formed inside the vacuuming roller 501. A plurality of partition plates 503 are equidistantly arranged around the center point of the vacuuming roller 501. Each partition plate 503 divides the suction chamber 502 into a plurality of separate chambers 504. A plurality of suction holes 505 are arranged from top to bottom on the outer wall of the vacuuming roller 501 at the corresponding position of each separate chamber 504. A first filter 506 and a second filter 507 are respectively inserted from the outside to the inside of each separate chamber 504. A first channel 508 is formed between the first filter 506 and two adjacent partition plates 503 and the inner wall of the suction chamber 502. A second channel 509 is formed between the second filter 507 and two adjacent partition plates 503 and the first filter 506. A third channel 510 is formed between the second filter 507 and two adjacent partition plates 503 and the inner wall of the suction chamber 502.

[0033] The top surface of the dust suction roller 501 is recessed with a receiving area 511, which is used to install the cover plate 512. When the cover plate 512 is installed, its lower end face forms a sealing fit with each partition plate 503.

[0034] A suction plate 6 is fixedly installed at the top of the support platform 5 at the corresponding position of the suction roller 501. The suction plate 6 is coaxially arranged with the suction roller 501 and the lower end face of the suction roller 501 is sealed and rotatably connected to the suction plate 6. The top surface of the suction plate 6 has a first air groove 600, a second air groove 601 and a third air groove 602 distributed in a counterclockwise direction. The first air groove 600 corresponds to the position of each third channel 510, the second air groove 601 corresponds to the position of each second channel 509 and the third air groove 602 corresponds to the position of each first channel 508. The bottom wall of the first air groove 600, the second air groove 601 and the third air groove 602 are all provided with suction holes 603 and suction holes 603 are sealed and connected to suction pipes 604. Each suction pipe 604 is connected to an external power source to suck up the gas in the first air groove 600, the second air groove 601 or the third air groove 602.

[0035] In use, the suction pipes 604 on the bottom walls of the first air tank 600, the second air tank 601, and the third air tank 602 are all connected to an external power source to draw gas from the first air tank 600, the second air tank 601, or the third air tank 602. The power source is preferably an "air pump". In the working state, each air pump draws gas from the first air tank 600, the second air tank 601, and the third air tank 602 outward through the corresponding suction pipe 604.

[0036] During operation, the suction roller 501 rotates counterclockwise, causing each individual separation chamber 504 to sequentially pass through the first air groove 600, the second air groove 601, and the third air groove 602. When the separation chamber 504 passes through the first air groove 600, since the position of the first air groove 600 corresponds to the position of the third channel 510, the gas outside the suction roller 501 is drawn into the separation chamber 504 through the suction hole 505. Each separation chamber 504 is provided with a first filter screen 506 and a second filter screen 507 sequentially from the outside to the inside. The mesh size of the first filter screen 506 is larger than that of the second filter screen 507 to block and filter metal debris in the air. The metal debris is blocked and remains in the first channel 508. Due to the volume of dust... The dust particles are smaller than the metal scraps, so they can pass smoothly through the first filter 506 and enter the second channel 509. The second filter 507 is used to filter the dust in the air. The dust is blocked and retained in the second channel 509. At this time, the clean air enters the third channel 510 and is guided by the air pump to be discharged from the first air groove 600 to the outside of the suction roller 501. The suction roller 501 rotates, causing each individual separation chamber 504 to pass through the first air groove 600 in sequence. When each separation chamber 504 passes through the first air groove 600, the metal scraps are retained in the first channel 508 and the dust is retained in the second channel 509. The clean air is discharged from the third channel 510 to complete the filtration of dust and metal scraps in the air.

[0037] Because the suction roller 501 is rotatably configured and sealed to the extraction disc 6, each individual separation chamber 504 sequentially passes through the first air groove 600, the second air groove 601, and the third air groove 602. After passing through the first air groove 600, the separation chamber 504 continues to rotate. At this time, metal debris remains in the first channel 508 of the separation chamber 504, and dust remains in the second channel 509. Then, the suction roller 501 rotates counterclockwise, causing each separation chamber 504 to sequentially reach the corresponding position in the second air groove 601 after passing through the first air groove 600. The second air groove 601 corresponds to the position of each second channel 509. The suction pipe 604 in the second air groove 601 draws in the gas in the second air groove 601 to carry out the dust particles remaining in the second channel 509. Furthermore, while the second air groove 601 sucks up the dust remaining in the second channel 509, it also carries out the dust particles remaining in the third channel 510, ensuring thorough cleaning and collection of the dust. During the above process, due to the blocking effect of the first filter screen 506, the metal debris remains in the second channel 509. Then, the dust suction roller 501 continues to rotate counterclockwise and causes each separation chamber 504 to reach the corresponding position of the third air groove 602 after passing through the first air groove 600 and the second air groove 601. The third air groove 602 corresponds to the position of each first channel 508. The suction pipe 604 in the third air groove 602 sucks up the gas in the third air groove 602 to carry out the metal debris remaining in the first channel 508, thus completing the thorough cleaning and collection of the metal debris.

[0038] Each filter screen has mounting ribs on both sides, and each partition plate 503 has mounting grooves at the mounting positions of the first filter screen 506 or the second filter screen 507. During installation, the first filter screen 506 or the second filter screen 507 is inserted into the separation chamber 504 through the cooperation between the mounting ribs on both sides and the corresponding mounting grooves. Then, the cover plate 512 is inserted into the receiving section 511 and fixedly covered on the top of the dust suction roller 501. When the cover plate 512 is installed, its lower end face forms a sealing fit with the top surface of each partition plate 503 and the top surface of the first filter screen 506 or the second filter screen 507, ensuring independent sealing between each separation chamber 504. The filter screens can be detached for easy daily maintenance and replacement.

[0039] A dust collection chamber 7 is fixedly provided on the side of the support table 5 corresponding to the first air groove 600. A dust collection cavity 700 is formed in the dust collection chamber 7 and a dust collection inlet 701 and a dust collection outlet 702 are respectively opened. A pressure plate 703 is provided on the outer edge of the outer opening of the dust collection outlet 702 and the outer side of the pressure plate 703 contacts and seals the outer surface of the dust collection roller 501. An extension shell 704 is connected to the dust collection inlet 701 and the extension shell 704 extends through and into the grinding box 1.

[0040] A fourth air groove 605 is formed on the top surface of the suction plate 6 between the third air groove 602 and the first air groove 600. The fourth air groove 605 is connected to the third channel 510 and has an air delivery hole 606 on its inner bottom wall. The air delivery hole 606 is sealed to an air delivery pipe 607, which is connected to an external power source to deliver external air into the suction roller 501. A dust return chamber 608 is fixed on the support platform 5 on the side corresponding to the fourth air groove 605. The dust return chamber 608 has a dust return port 613. Furthermore, a pressure plate 703 is provided at the outer edge of the dust return port 613. The outer side of the pressure plate 703 contacts and seals with the outer surface of the dust collection roller 501. The air supply pipe 607 is connected to an external power source to send external air into the third channel 510. The external air enters the third channel 510 and then passes through the second channel 509 and the first channel 508. The dust and metal particles remaining in the second channel 509 and the first channel 508 are sent back to the dust return chamber 608 for collection through the suction hole 505.

[0041] A number of first return pipes 609 are arranged on one side of the dust return chamber 608, and all the first return pipes 609 are connected to a first main pipe 610. A number of second return pipes 611 are arranged on one side of the dust collection chamber 7, and all the second return pipes 611 are connected to a second main pipe 612. The first main pipe 610 and the second main pipe 612 are connected to a power source to return the dust and metal particles in the dust return chamber 608 to the dust collection chamber 7.

[0042] In use, the support platform 5 is fixedly equipped with a dust collection chamber 7 on the side corresponding to the first air groove 600. When the dust suction roller 501 rotates and causes each dust collection chamber 700 to pass through the first air groove 600, since the position of the first air groove 600 corresponds to the position of the third channel 510, the gas outside the dust suction roller 501 is sucked into the separation chamber 504 through the suction hole 505. At this time, the suction hole 505 corresponding to the dust collection chamber 700 corresponds to the dust collection outlet 702 of the dust collection chamber 7. At this time, the metal chips and dust generated by grinding in the grinding box 1 are discharged from the extended shell. The dust collector 704 and the dust collection inlet 701 enter the dust collection chamber 7, and then enter each individual separation chamber 504 through the dust collection outlet 702. The pressure plate 703 ensures a sealed contact between the dust collection roller 501 and the dust collection outlet 702. The dust collection roller 501 then continues to rotate, causing the dust collection chamber 700 to sequentially pass through the second air groove 601, the third air groove 602, and the fourth air groove 605. When passing through the second air groove 601, the dust in the second channel 509 is drawn and collected. When passing through the third air groove 602, the metal debris in the first channel is removed. The fourth air tank 605 is connected to the third channel 510 and sealed with an air supply pipe 607. The air supply pipe 607 is connected to an external power source (preferably an air pump) to send external gas into the fourth air tank 605 and into the suction roller 501. The support platform 5 is fixedly provided with a dust return chamber 608 on the side corresponding to the fourth air tank 605. The dust return chamber 608 has a dust return port 613, and the suction roller 501 is sealed to the dust return port 613 by a pressure plate 703. The rotation of the suction roller 501 causes one of the separation chambers 504 to connect with the fourth air tank. At position 605, the separation chamber 504 has passed through the first air groove 600, the second air groove 601 and the third air groove 602 respectively and completed the separation and collection of dust and metal debris. The position of the fourth air groove 605 corresponds to the third channel 510. The external air pump introduces gas from the fourth air groove 605 into the third channel 510. The gas passes through the second channel 509 and the first channel 508 from the third channel 510 and is discharged from the suction hole 505 to the dust collection roller 501. The gas discharged from the suction hole 505 enters the dust return chamber 608 for collection.

[0043] Gas is pumped from the fourth air tank 605 into the third channel 510. The gas passes through the second channel 509 and the first channel 508 in sequence and is discharged through the dust suction hole. During the process, the gas passes through the second filter screen 507 and the first filter screen 506 respectively. Due to the force generated by the gas, the dust stuck on the second filter screen 507 and the metal debris stuck on the first filter screen 506 can be sent back to the dust return chamber 608 (a transparent window is provided on the front side of the dust return chamber 608 to facilitate observation of the dust return situation in the dust return chamber 608), so as to avoid the filtration effect of the first filter screen 506 or the second filter screen 507 being affected by the accumulation of metal debris or dust.

[0044] Furthermore, the first main pipe 610 and the second main pipe 612 are connected to a power source (preferably an "air pump") to send the dust and metal particles in the dust return chamber 608 back to the dust collection chamber 7, and then send them back to the dust collection roller 501 from the dust collection chamber 7 to perform secondary separation of the gas in the dust return chamber 608, effectively improving the suction and separation effect of the dust collection roller 501 on dust and metal debris;

[0045] Specifically, the sealing connection between the dust collection roller 501 and the extraction disc 6 is achieved by providing a sealing ring on the top surface of the extraction disc 6, rotating the dust collection roller 501 above the extraction disc 6 and sealing it with the extraction disc 6, and isolating the first air groove 600, the second air groove 601, the third air groove 602 and the fourth air groove 605 when the sealing ring contacts and seals with the end of the dust collection roller 501.

[0046] A through hole 8 is provided at the center of the dust collection roller 501. A drive shaft 800 is located at the center of the through hole 8 and is fixed in the through hole 8 by several reinforcing rods 801. The lower end of the drive shaft 800 passes through the suction plate 6 and the support platform 5 and extends to the bottom of the support platform 5. A support frame 802 is fixed below the support platform 5. A drive unit 803 is provided on the support frame 802 and the output shaft of the drive unit 803 is drivenly connected to the drive shaft 800 through a coupling. The drive unit 803 provides power to the drive shaft 800 to drive the dust collection roller 501 to rotate.

[0047] In use, the connection strength between the drive shaft 800 and the suction roller 501 is improved by the reinforcing rods 801. The lower end of the drive shaft 800 passes through the extraction plate 6 and the support table 5 and extends to the bottom of the support table 5. The support frame 802 is equipped with a drive unit 803 (preferably a "speed-regulating motor"). The output shaft of the drive unit 803 is driven and connected to the drive shaft 800 through a coupling. The coupling ensures that the drive unit 803 can stably drive the suction roller 501 to rotate. The suction roller 501, the drive shaft 800, and the extraction plate 6 are coaxial to ensure the stability of the suction roller 501 in use.

[0048] The clamping mechanism 2 includes a fixed base plate 200, a cover 201 fixed at the center of the top surface of the fixed base plate 200, and a rotating base 202 at the center of the top surface of the fixed base plate 200. The rotating base 202 has a U-shaped structure and a rotating part 203 extends from the center of the lower end surface. The rotating base 202 is rotatably mounted above the fixed base plate 200 through the cooperation between the rotating part 203 and the cover 201.

[0049] A servo motor 204 is fixed at the center of the lower end face of the fixed base plate 200. The output shaft of the servo motor 204 passes through the fixed base plate 200 and the rotating part 203 and extends into the rotating base 202. Two clamping plates 205 are arranged in front and behind the two vertical ends of the rotating base 202. The two clamping plates 205 are slidably arranged in the rotating base 202 through the guide rail assembly. Each clamping plate 205 has a mating recess 206 in the middle of its bottom surface. Each mating recess 206 is provided with a sliding guide 207. The output shaft of the servo motor 204 extends into the mating recess 206 and is connected to a cam disk 208. Two arc-shaped rail grooves 209 are symmetrically opened on the cam disk 208. The two sliding guides 207 can be slidably installed in the two arc-shaped rail grooves 209 of the cam disk 208 respectively.

[0050] The guide rail assembly includes a rail base 210 and a slider 211 that engages with and slides with the rail base 210. The rail base 210 and the slider 211 are connected between the inner sidewalls of the two vertical ends of the rotating base 202 and the two clamping plates 205. The sliding direction of the rail base 210 and the slider 211 is perpendicular to the two clamping plates 205. The guide rail assembly guides the two clamping plates 205 to always move in opposite directions or away from each other along a straight line.

[0051] In use, the sword to be sharpened is inserted into the sharpening chamber 1 so that the lower end of its hilt abuts against the upper surface of the cam disc 208. At this time, the servo motor 204 is started, driving its output shaft to rotate. The rotation of the output shaft drives the cam disc 208 to rotate. The rotation of the cam disc 208 guides the two sliding guides 207 to slide along the corresponding arc-shaped rail grooves 209. Through the sliding engagement between the two sliding guides 207 and the arc-shaped rail grooves 209, and the sliding engagement between the two clamping plates 205 and the rotating base 202, the two clamping plates 205 are driven to move towards each other and clamp and fix the sword hilt. At this point, one side of the sword can be polished. After the sword is polished on one side, the servo motor 204 continues to drive the cam disk 208 to rotate 180°. Since the sliding guide 207 has abutted against one end of each corresponding arc-shaped rail groove 209, the rotation of the cam disk 208 keeps the two clamping plates 205 clamped and drives the rotating base 202 to rotate 180°, completing the flipping of the sword. During the flipping process, the two clamping plates 205 always clamp the sword. After the sword is flipped, the other side of the sword can be polished to complete the double-sided polishing of the sword.

[0052] An elastic return unit connects the rotating base 202 and the fixed base plate 200. This elastic return unit applies a certain force to the rotating base 202, making it difficult for it to rotate around the rotating part 203. When the output shaft of the servo motor 204 drives the cam disk 208 to rotate, the force applied by the elastic return unit to the rotating base 202 prevents it from rotating, causing the two sliding guides 207 to slide along their corresponding arc-shaped grooves 209 to clamp the sword. However, after the two clamping plates 205 clamp the sword, when the servo motor 204 drives the cam disk 208 to continue rotating, the two sliding guides 207 have already moved and reached the final position of the arc-shaped grooves 209. At this point, the rotational force generated by the cam disk 208 is applied to the rotating base 202 through the sliding guides 207, clamping plates 205, and guide rail assembly. 02, thereby driving the rotating base 202 to rotate, thus realizing the following: first clamping the sword (at this time, one side of the sword is polished), and then rotating the sword (at this time, the other side of the sword is polished). After both sides of the sword are polished, the servo motor 204 first drives the sword to rotate. During the rotation, due to the force of the elastic return unit, the two clamping plates 205 will not loosen the sword handle. When the sword returns to its original position and rotates again, the two clamping plates 205 will loosen the sword handle. At this time, the sword can be removed and replaced with a new sword for subsequent polishing operations. To further explain, the elastic return unit can be a torsion spring or a tension spring. The two ends of the torsion spring or tension spring are fixedly connected to the rotating base 202 and the fixed base plate 200, respectively. When the clamping mechanism 2 is in a non-working state, the torsion spring or tension spring is not under force. When the clamping mechanism 2 clamps the sword handle and flips it over, the torsion spring or tension spring is in a stretched state.

[0053] The inner ring of the cover 201 is provided with a first rolling groove, and the outer ring of the rotating part 203 is provided with a second rolling groove. In use, the rotating part 203 is located inside the cover 201 and the position of the second rolling groove corresponds to the position of the first rolling groove. Several balls are movably arranged in the first rolling groove and the second rolling groove. The rotating base 202 is rotatably connected to the fixed base plate 200 through the rotational cooperation between the rotating part 203 and the cover 201.

[0054] The output shaft of the servo motor 204 passes through the fixed base plate 200 and the rotating part 203 and extends to the rotating base 202. The fixed base plate 200 and the rotating base 202 are both fixed with rotating bushings at the corresponding positions of the output shaft to ensure the smooth rotation of the output shaft of the servo motor 204.

[0055] Both clamping plates 205 have through windows 212 in the middle section. A fixed base plate 213 is provided on the outside of the through window 212. A fixed seat 214 is provided on the inner end face of the fixed base plate 213. A mating groove 215 is provided on the inner end face of the fixed seat 214, and a mating slide 216 is movably provided in the mating groove 215. Several springs 217 are fixedly connected between the end face of the mating slide 216 located in the mating groove 215 and the bottom wall of the mating groove 215. A clamping plate 218 is fixedly provided on the opposite ends of the two slides. Several enclosing columns 219 are arranged correspondingly on the opposite ends of the clamping plates 218. A mating gap 220 is formed between each adjacent enclosing column 219, and the size of the mating gap 220 is adapted to the size of the enclosing column 219. The two clamping plates 218 are staggered vertically, and each enclosing column 219 corresponds to the position of the mating gap 220 of the opposite clamping plate 218.

[0056] When in use, when the servo motor 204 drives the cam disk 208 to rotate, it causes the two sliding guides 207 to slide along the corresponding arc-shaped rail groove 209. The two sliding guides 207 drive the two clamping plates 205 to move towards each other through the limit between the guide rail assembly to clamp the handle and fix the sword, so as to prevent the sword from loosening or shifting during polishing or flipping.

[0057] Furthermore, a spring element 217 is fixedly connected between the end face of the sliding block 216 located in the groove and the bottom wall of the inner groove 215. When the two clamping plates 218 clamp and fix the sword handle, the sliding block 216 should overcome the spring element 217 to slide adaptively along the corresponding groove 215, so that the two clamping plates 218 can achieve adaptive clamping of the sword handle. During the clamping process, the elastic restoring force of the spring element 217 can further improve the clamping stability of the two clamping plates 218 for the sword handle.

[0058] The two clamping plates 218 are arranged with several enclosing columns 219 facing each other. A fitting gap 220 is formed between each adjacent enclosing column 219. The two clamping plates 218 are staggered, and each enclosing column 219 corresponds to the fitting gap 220 of the other clamping plate 218. The two rows of enclosing columns 219 on each clamping plate 218 form a V-shaped interval with the clamping plate 218. The two V-shaped intervals can ensure the stable positioning of the sword handle. When working, the two clamping plates 218 move towards each other and clamp the sword handle, causing each enclosing column 219 to enter the fitting gap 220 of the other clamping plate 218. The staggered enclosing clamping of the two clamping plates 218 ensures the stable clamping of the sword handle. At the same time, this clamping and limiting method allows the two clamping plates 218 to adapt to the clamping and fixing of sword handles of different sizes, effectively improving the flexibility of the device.

[0059] The lifting mechanism includes a lifting section 4 formed inside the grinding box 1, a positioning screw 400 rotatably disposed within the lifting section 4, a guide rod 401 fixedly disposed within the lifting section 4, and a lifting seat 402 slidably disposed outside the guide rod 401. The lifting seat 402 has a threaded hole 403 adapted to the positioning screw 400. One end of the positioning screw 400 extends through to the outside of the grinding box 1 and is connected to a power motor 404 via a coupling. The polishing mechanism includes a polishing seat 3 connected to the lifting seat 402. A polishing motor 300 is fixedly disposed on the front side of the polishing seat 3, and a polishing disc 301 is driven and connected to the front side of the polishing motor 300.

[0060] In use, the lifting seat 402 is initially at its highest point. At this time, the sword is clamped by the clamping mechanism 2. The power motor 404 (fixed to the outside of the grinding box 1 by the motor frame) is started and drives the lead screw to rotate. The rotation of the lead screw drives the lifting seat 402 to move up and down through the cooperation between the lead screw and the threaded hole 403 and the sliding cooperation between the lifting seat 402 and the guide rod 401. During the lifting process, the grinding motor 300 is started and the sword is polished by the grinding disc 301. The lifting seat 402 drives the grinding motor 300 and the grinding disc 301 to descend and then rise to complete the polishing work on one side of the sword blank. Then the clamping mechanism 2 flips the sword (the position of the polishing mechanism is higher than the sword during the flip to avoid the sword colliding with the polishing mechanism during the flip). The lifting mechanism and the polishing mechanism repeat the above work to polish the other side of the sword.

[0061] The polishing method of the sword polishing equipment includes the following steps: S1. Open the cover of the polishing box 1, place the sword to be polished into the polishing box 1, clamp the sword handle with the clamping mechanism 2, and then close the cover; S2. The polishing mechanism is driven up and down by the lifting mechanism to polish the sword; S3. After polishing one side of the sword, the sword is flipped over by the clamping mechanism 2, and the lifting mechanism and polishing mechanism are repeated to polish the other side of the sword; S4. After polishing both sides, the clamping mechanism 2 drives the sword to rotate back to the initial position, and then the clamping mechanism 2 releases the sword and takes out the polished sword; S5. During the polishing process, the drive unit 803 is started to control the drive shaft 800 to rotate, so as to drive the dust suction roller 501 to rotate, and the suction pipe 60 in the first air groove 600, the second air groove 601 and the third air groove 602 to remove the dust suction pipe 60. 4. Connect to an external power source to draw gas from the first air groove 600, the second air groove 601 and the third air groove 602. Connect the air supply pipe 607 in the fourth air groove 605 to the external power source to send external air from the fourth air groove 605 into the dust collection roller 501. S6. The rotation of the dust collection roller 501 causes each separation chamber 504 to pass through the first air groove 600, the second air groove 601, the third air groove 602 and the fourth air groove 605 in sequence. When passing through the first air groove 600, since the position of the first air groove 600 corresponds to the position of the third channel 510, and the support table 5 is fixed with a dust collection chamber 7 on the side corresponding to the first air groove 600, the dust collection roller 501 draws metal chips and dust particles generated by grinding in the grinding box 1 from the dust collection chamber 7 into the corresponding separation chamber 504 through the suction hole 505.

[0062] S7. The separation chamber 504 is provided with a first filter 506 and a second filter 507 from the outside to the inside. The first filter 506 blocks metal debris in the air and retains it in the first channel 508. The second filter 507 blocks dust in the air and retains it in the second channel 509. Clean air enters the third channel 510 and is discharged from the first air groove 600 to the outside of the suction roller 501. S8. The drive unit 803 drives the suction roller 501 to continue rotating and passing through the second air groove 601 and the third air groove 602, and then through the first... When passing through the second air groove 601, the dust in the second channel 509 is drawn and collected. When passing through the third air groove 602, the metal debris in the first channel is drawn and collected. S9, the drive unit 803 drives the dust collection roller 501 to continue rotating and pass through the fourth air groove 605. The fourth air groove 605 is connected to the third channel 510 and sealed with an air supply pipe 607. The air supply pipe 607 is connected to an external power source to send external gas into the fourth air groove 605 and into the dust collection roller 501. The support platform 5 is located in the fourth air groove 605. A dust return chamber 608 is fixedly provided on the side. The dust return chamber 608 has a dust return port 613, and the dust suction roller 501 is sealed to the dust return port 613 by a pressure plate 703. The rotation of the dust suction roller 501 causes one of the separation chambers 504 to align with the fourth air groove 605. At this time, the separation chamber 504 has passed through the first air groove 600, the second air groove 601, and the third air groove 602 respectively, and completed the separation and collection of dust and metal debris. The position of the fourth air groove 605 corresponds to the third channel 510. An external air pump draws gas from the fourth air groove. 605 is introduced into the third channel 510. The gas passes through the third channel 510, the second channel 509, and the first channel 508, and is discharged through the suction hole 505 to the dust collection roller 501. The gas discharged through the suction hole 505 enters the dust return chamber 608 for collection. S10, the first main pipe 610, and the second main pipe 612 are connected to a power source to send the dust and metal particles in the dust return chamber 608 back to the dust collection chamber 7, and then back to the dust collection roller 501 from the dust collection chamber 7 for secondary separation of the gas in the dust return chamber 608.
