Description

Technical Field

[0001] This invention belongs to the field of sandpaper cutting, specifically a cutting device and method for ceramic flocked sandpaper. Background Technology

[0002] Sandpaper is a material used for grinding surfaces such as metal and wood to make them smooth and shiny. It is usually made by gluing various abrasive grains onto a base paper. Depending on the abrasive material, there are many types, such as diamond sandpaper, artificial diamond sandpaper, and glass sandpaper. Sandpaper used on sanders is generally disc-shaped and consists of a base, an adhesive layer, an abrasive layer, and a backing adhesive layer. During the manufacturing process, it needs to be circumferentially cut with a cutting knife.

[0003] In existing technologies, when circumferentially cutting sandpaper masterbatch, the abrasive layer on the surface of the sandpaper causes significant wear on the cutting blade. With prolonged use, the cutting blade becomes less sharp, resulting in burrs on the edges of the cut circular sandpaper, affecting its quality. Furthermore, when the cutting blade pierces the sandpaper masterbatch, it must pass through the adhesive layer, and the adhesive in the adhesive layer easily adheres to the cutting blade, thus affecting its cutting effect. In addition, when cutting circular sandpaper, the up-and-down movement of the cutting blade scrapes the adhesive from the adhesive layer onto the cut, causing the edges of the circular sandpaper to stick to the sandpaper masterbatch after cutting, making it difficult to remove the material.

[0004] Therefore, the present invention provides a cutting device and a cutting method for sand ceramic flocked sandpaper. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problems encountered when circumferentially cutting sandpaper masterbatch, such as significant wear on the cutting blade due to the abrasive layer on the sandpaper surface, leading to dulling of the blade over time and resulting in burrs on the edges of the cut circular sandpaper, thus affecting the quality of the circular sandpaper, and the adhesion of adhesive layer to the cutting blade when the cutting blade pierces the sandpaper masterbatch, further impacting the cutting effect, and the scraping of adhesive layer onto the cut seam during the cutting of circular sandpaper by the up-and-down movement of the cutting blade, causing the edges of the circular sandpaper to stick to the sandpaper masterbatch, making it difficult to remove, this invention proposes a cutting device and method for ceramic flocked sandpaper.

[0015] A cutting method for a cutting device for flocked sandpaper on abrasive ceramics, applicable to the aforementioned cutting device for flocked sandpaper on abrasive ceramics, is described below: S1: Place the sandpaper masterbatch on the cutting table, start the hydraulic cylinder, drive the support plate to move downward, so that the blade passes through the collar, and apply the anti-sticking agent to the blade surface through the feeding component. Continue to control the blade to move downward and pierce the sandpaper masterbatch. S2: Start the motor to drive the housing to rotate, causing the cutter to rotate and cut the sandpaper masterbatch into a circle; S3: After the sandpaper masterbatch is circumcised, the control support plate is reset upward, and the top ring is moved upward through the linkage component to push the circumcised circular sandpaper out of the sandpaper masterbatch.

[0016] The beneficial effects of this invention are as follows: 1. The present invention discloses a cutting device and method for abrasive ceramic flocked sandpaper. A third spring is provided to cause the grinding blocks to press against the blade and grind the blade. As the blade rotates, the grinding by several grinding blocks keeps the blade sharp and improves the smoothness of the edge of the circular sandpaper. After the blade passes through several grinding blocks, it passes through several sponge pads. The sponge pads can scrape off the shavings generated on the blade surface due to grinding. The shavings scraped off the blade are discharged from the cutting table along the first and second feeding grooves.

[0017] 2. The present invention discloses a cutting device and cutting method for abrasive ceramic flocked sandpaper. By cooperating with the extrusion block and the feeding groove, the anti-sticking agent in the feeding groove enters the flow groove and is absorbed by the sponge. The anti-sticking agent is then applied to the outer wall of the blade by the sponge to prevent adhesive residue from adhering to the surface of the sandpaper masterbatch when the blade cuts it.

[0018] 3. The present invention discloses a cutting device and method for ceramic flocked sandpaper. The support plate is moved upward by a hydraulic cylinder. The top ring moves upward by the cooperation of the locking block and the fixing ring, which helps to separate the circular sandpaper cut off from the sandpaper masterbatch, making it easier to pick up the material. The top ring can lift the circular sandpaper cut off at one time to avoid wrinkles on the edge of the circular sandpaper. After the circular sandpaper is lifted, the locking block and the fixing ring are separated by the pressure of the top plate. Under the action of the fourth spring, the connecting shaft and the top ring move downward and reset, which facilitates the feeding of the next circular sandpaper.

[0019] 4. The present invention provides a cutting device and method for abrasive ceramic flocked sandpaper. By pressing the turntable, the area where the sandpaper masterbatch is to be circumferentially cut is made to fit against the cutting table. This avoids the sandpaper masterbatch from bulging at the circumferentially cut area due to the downward pressure of the weight at both ends of the sandpaper masterbatch, which would affect the accuracy of cutting the circular sandpaper. When the sleeve rotates, it drives the fixing plate to rotate on the turntable. The anti-slip pads keep the turntable stationary, thereby preventing wear on the surface of the sandpaper masterbatch when the sleeve rotates. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 12As shown, the present invention provides a technical solution: a cutting device for sandpaper used in ceramic flocking, comprising a processing table 1, a hydraulic cylinder 2 fixedly connected to the top of the inner wall of the processing table 1, a support plate 3 fixedly connected to the output end of the hydraulic cylinder 2, a motor 4 fixedly connected to the inner wall of the support plate 3, a sleeve 5 fixedly connected to the output end of the motor 4, a bracket 6 fixedly connected to the outer wall of the sleeve 5, a cutter 7 fixedly connected to the bottom of the bracket 6, a feeding assembly provided inside the sleeve 5, two first sliding shafts 8 symmetrically slidably connected to the inner wall of the bracket 6 with the cutter 7 as the center, a collar 9 fixedly connected to the bottom of the two first sliding shafts 8, a sponge 12 provided on the inner wall of the collar 9, a limit block 11 fixedly connected to the top of the two first sliding shafts 8, a first spring 10 sleeved on the outer wall of the first sliding shaft 8, the top of the first spring 10 fixedly connected to the bracket 6, the bottom of the first spring 10 fixedly connected to the collar 9, and a cutting table 26 fixedly connected to the inner wall of the processing table 1 and below the support plate 3.

[0025] Using the above technical solution, the sandpaper masterbatch is placed on the cutting table 26. The hydraulic cylinder 2 is started, which drives the support plate 3 to move downward, causing the motor 4 to move downward, which in turn drives the sleeve 5 to move downward, causing the bracket 6 to move downward, which in turn drives the collar 9 to move downward. When the collar 9 presses against the sandpaper masterbatch, as the bracket 6 continues to move downward, the first sliding shaft 8 slides inside the bracket 6, pressing the first spring 10. At this time, the cutter 7 presses against the sandpaper masterbatch. The motor 4 is started, which drives the sleeve 5 to rotate, causing the bracket 6 to rotate, which in turn drives the cutter 7 to rotate, cutting the sandpaper masterbatch into a circle. While the sleeve 5 moves downward, an anti-sticking agent is added to the sponge wiping 12 through the feeding component. When the cutter 7 passes down through the collar 9, the anti-sticking agent is applied to the outer wall of the cutter 7 through the sponge wiping 12 to prevent adhesive residue from adhering to the surface of the cutter 7 when cutting the sandpaper masterbatch.

[0026] Specifically, the feeding assembly includes a cavity 15, which is located inside the sleeve 5. A push rod 18 is slidably connected to the bottom of the sleeve 5. The top of the push rod 18 extends into the cavity 15 and has a feeding groove 19. A sliding groove 20 is formed on the top of the inner wall of the cavity 15. The push rod 18 fits against the inner wall of the sliding groove 20. A squeezing block 21 is fixedly connected to the top of the inner wall of the sliding groove 20. An infusion tank 16 is formed inside the sleeve 5 and communicates with the sliding groove 20. A flow groove 46 is formed inside the collar 9. A flexible tube 17 is provided between the flow groove 46 and the infusion tank 16. A fixing plate 23 is fixedly connected to the bottom of the push rod 18. A second spring 22 is sleeved on the outer wall of the push rod 18. The top of the second spring 22 is fixedly connected to the sleeve 5, and the bottom of the second spring 22 is fixedly connected to the fixing plate 23.

[0027] Through the above technical solution, the anti-sticking agent is loaded into the cavity 15, and part of the anti-sticking agent is stored in the feed trough 19. When the sleeve 5 moves downward, the fixing plate 23 presses against the sandpaper masterbatch. As the sleeve 5 continues to move downward, the push rod 18 slides in the cavity 15 and inserts into the slide groove 20, pressing the second spring 22. At this time, the extrusion block 21 is inserted into the feed trough 19. With the extrusion block 21, the anti-sticking agent in the feed trough 19 flows upward and enters the flow trough 46 along the infusion trough 16 and the hose 17. The anti-sticking agent entering the flow trough 46 is absorbed by the sponge 12. After the cutting of a round sandpaper is completed, the sleeve 5 is retracted upward by the hydraulic cylinder 2. After the extrusion of the sandpaper masterbatch is lost, the push rod 18 moves downward under the action of the second spring 22, which drives the feed trough 19 to move downward, so as to store the anti-sticking agent again.

[0028] Specifically, a turntable 24 is rotatably connected to the bottom of the fixed plate 23, and an anti-slip pad 25 is provided on the bottom of the turntable 24.

[0029] With the above technical solution, when the sleeve 5 moves downward, the turntable 24 first presses against the sandpaper masterbatch. Through the pressing of the turntable 24, the position of the sandpaper masterbatch that is circumferentially cut is made to fit against the cutting table 26, avoiding the sandpaper masterbatch from bulging due to the downward pressure of the gravity at both ends, which would affect the accuracy of the circular sandpaper cutting. When the sleeve 5 rotates, it drives the fixing plate 23 to rotate on the turntable 24. The anti-slip pad 25 keeps the turntable 24 stationary, thereby preventing wear on the surface of the sandpaper masterbatch when the sleeve 5 rotates.

[0030] Specifically, the bottom of the collar 9 is symmetrically fixedly connected to two mounting brackets 13, and the inner walls of the two mounting brackets 13 are rotatably connected to pulleys 14.

[0031] With the above technical solution, when the collar 9 moves downward, the pulley 14 first presses against the sandpaper masterbatch. As the sandpaper masterbatch is cut in the ring, the collar 9 rotates around the sandpaper masterbatch, causing the pulley 14 to slide on the sandpaper masterbatch, thus avoiding wear on the surface of the sandpaper masterbatch caused by the collar 9.

[0032] Specifically, the inner wall of the cutting table 26 is provided with a second feeding groove 44. Several connecting frames 45 are fixedly connected at equal intervals to the inner wall of the second feeding groove 44. The top of the connecting frames 45 is set as a symmetrical inclined surface. An mounting plate 27 is slidably connected to the inner wall of the second feeding groove 44 and above the connecting frames 45. The inner wall of the mounting plate 27 is provided with a first feeding groove 28. The inner wall of the first feeding groove 28 is set as an inclined surface. Several grinding blocks 32 are fixedly connected at equal intervals to the inner wall of the first feeding groove 28. Several second sliding shafts 29 are fixedly connected at equal intervals to the inner wall of the cutting table 26. A first slider 30 is slidably connected to the outer wall of the second sliding shaft 29. The first slider 30 is fixedly connected to the mounting plate 27. A third spring 31 is sleeved on the outer wall of the second sliding shaft 29. The top of the third spring 31 is fixedly connected to the first slider 30, and the bottom of the third spring 31 is fixedly connected to the cutting table 26.

[0033] With the above technical solution, when the cutting tool 7 moves downward, the cutting tool 7 pierces the sandpaper masterbatch and inserts into the first feeding groove 28. The cutting tool 7 is controlled to rotate to perform circumferential cutting on the sandpaper masterbatch. When the cutting tool 7 rotates to the grinding block 32, the grinding block 32 is pressed against the cutting tool 7 by the third spring 31 to grind the cutting tool 7. Thus, as the cutting tool 7 rotates, the grinding of several grinding blocks 32 keeps the cutting tool 7 sharp and improves the smoothness of the edge of the circular sandpaper.

[0034] Specifically, several sponge pads 33 are fixedly connected at equal intervals to the inner wall of the first feeding trough 28 and the side away from the grinding block 32.

[0035] With the above technical solution, as the cutting tool 7 rotates, after the cutting tool 7 passes through several grinding blocks 32, it passes through several sponge pads 33. The sponge pads 33 can scrape off the shavings generated on the surface of the cutting tool 7 due to grinding. The shavings scraped off the cutting tool 7 are discharged from the cutting table 26 along the first feeding groove 28 and the second feeding groove 44.

[0036] Specifically, the inner wall of the cutting table 26 is equidistantly connected with several connecting shafts 35. A slide plate 36 is fixedly connected to the outer wall of each connecting shaft 35, and the slide plate 36 is slidably connected to the cutting table 26. A fourth spring 37 is sleeved on the outer wall of the connecting shaft 35. The bottom of the fourth spring 37 is fixedly connected to the slide plate 36, and the top of the fourth spring 37 is fixedly connected to the cutting table 26. The bottom of the connecting shaft 35 penetrates the cutting table 26. A fixing ring 38 is fixedly connected to the outer wall of the connecting shaft 35 and located below the cutting table 26. A linkage assembly is provided at the bottom of the support plate 3. A top ring 34 is slidably connected to the top of the cutting table 26, and several connecting shafts 35 are fixedly connected to the top ring 34. The linkage assembly includes two L-shaped frames 47, which are symmetrical. Fixedly installed at the bottom of the support plate 3, two L-shaped frames 47 both penetrate the cutting table 26, and a mounting ring 39 is fixedly connected between the two L-shaped frames 47. Several locking blocks 41 are equidistantly connected to the inner wall of the mounting ring 39. The bottom of the locking blocks 41 is set as an inclined surface. The locking blocks 41 are located directly above the fixed ring 38. Several fifth springs 40 are fixedly connected at equal intervals inside the mounting ring 39. One end of the fifth spring 40 is fixedly connected to the locking block 41. Several top plates 43 are fixedly connected at equal intervals at the bottom of the cutting table 26. The top plates 43 are located directly above the locking blocks 41. Several through slots are equidistantly opened on the top of the mounting ring 39. The top plates 43 fit against the inner wall of the through slots. The top of the locking blocks 41 is opened with an inclined slot 42 that cooperates with the top plates 43.

[0037] Through the above technical solution, during the circumferential cutting of sandpaper masterbatch, the support plate 3 moves downward, driving the two L-shaped frames 47 to move downward, causing the mounting ring 39 to move downward, and driving the locking block 41 to move downward. When the locking block 41 presses against the fixing ring 38, the fixing ring 38 pushes the inclined surface at the bottom of the locking block 41, causing the locking block 41 to move and press the fifth spring 40. When the locking block 41 passes through the fixing ring 38, under the action of the fifth spring 40, the locking block 41 returns to its original position. After the circumferential cutting of sandpaper masterbatch is completed, the support plate 3 is controlled to move upward, driving the two L-shaped frames 47 to move upward, causing the mounting ring 39 to move upward, and driving the locking block 41 to move upward. At this time, the straight surface at the top of the locking block 41 hooks the fixing ring 38. Under the pull of the locking block 41, the fixing ring 38 moves upward, causing the connecting shaft 35 to move upward, driving the top ring 34 to move upward, and passing through the top ring... The upward push of the top ring 34 helps separate the circumcised circular sandpaper from the sandpaper masterbatch, making it easier to remove. The top ring 34 can also lift the circumcised circular sandpaper in one go, preventing the edges of the circular sandpaper from wrinkling. As the connecting shaft 35 moves upward, it drives the sliding plate 36 to move upward, pressing the fourth spring 37. As the support plate 3 continues to move upward, the top plate 43 is inserted into the mounting ring 39 through the through slot and presses against the inclined groove 42 on the top of the locking block 41. Under the action of the top plate 43, the locking block 41 is pushed to move, pressing the fifth spring 40 again. After the locking block 41 moves, it separates from the fixing ring 38 and loses the pull of the locking block 41. Under the action of the fourth spring 37, the connecting shaft 35 and the top ring 34 move downward and reset, making it easier to feed the next circular sandpaper. This process is repeated to prevent the circular sandpaper from sticking to the sandpaper masterbatch after circumcising and being difficult to remove.

[0038] A cutting method for a cutting device for flocked sandpaper on abrasive ceramics, applicable to the aforementioned cutting device for flocked sandpaper on abrasive ceramics, is described below: S1: Place the sandpaper masterbatch on the cutting table 26, start the hydraulic cylinder 2, drive the support plate 3 to move downward, so that the cutter 7 passes through the collar 9, and apply the anti-sticking agent to the surface of the cutter 7 through the feeding component. Continue to control the cutter 7 to move downward and pierce the sandpaper masterbatch. S2: Start motor 4, drive box 5 to rotate, and make cutter 7 rotate to cut sandpaper masterbatch into a circle; S3: After the sandpaper masterbatch is circumcised, the control support plate 3 is reset upward, and the top ring 34 is moved upward through the linkage component to push the circumcised circular sandpaper out of the sandpaper masterbatch.

[0039] In use, the anti-sticking agent is loaded into the cavity 15, and some anti-sticking agent is stored through the feed chute 19. The sandpaper masterbatch is placed on the cutting table 26. The hydraulic cylinder 2 is started, which moves the support plate 3 downward, causing the motor 4 to move downward, which in turn moves the sleeve 5 downward, causing the bracket 6 to move downward, which in turn moves the collar 9 downward. When the collar 9 moves downward, the pulley 14 first presses against the sandpaper masterbatch. After the pulley 14 presses against the sandpaper masterbatch, as the bracket 6 continues to move downward, the first sliding shaft 8 slides inside the bracket 6, compressing the first spring 10. At this time, the cutter 7 pierces the sandpaper masterbatch and inserts into the first feed chute 28. The motor 4 is started, which drives the sleeve 5 to rotate, causing the bracket 6 to rotate, which in turn drives the cutter 7 to rotate, cutting the sandpaper masterbatch into a circle. When the cutter 7 rotates to the grinding block... At position 32, the third spring 31 causes the grinding block 32 to press against the cutter 7 and grind the cutter 7. As the cutter 7 rotates, the grinding by the grinding blocks 32 keeps the cutter 7 sharp and improves the smoothness of the circular sandpaper edge. After the cutter 7 passes through the grinding blocks 32, it passes through the sponge pads 33. The sponge pads 33 can scrape off the shavings generated on the surface of the cutter 7 due to grinding. The shavings scraped off the cutter 7 are discharged from the cutting table 26 along the first feed groove 28 and the second feed groove 44. As the sandpaper masterbatch is circumferentially cut, the collar 9 rotates around the sandpaper masterbatch, driving the pulley 14 to slide on the sandpaper masterbatch, avoiding wear on the surface of the sandpaper masterbatch caused by the collar 9. When the sleeve 5 moves downward, the turntable 24 first presses against the sandpaper masterbatch. The paper masterbatch, pressed by the turntable 24, is made to adhere to the cutting table 26 at the circumferential cut position, preventing the circumferential cut position from bulging due to the downward pressure of the weight at both ends of the sandpaper masterbatch, which would affect the accuracy of the circular sandpaper cutting. As the sleeve 5 continues to move downward, the push rod 18 slides in the cavity 15 and inserts into the slide groove 20, pressing the second spring 22. At this time, the extrusion block 21 is inserted into the feed groove 19. With the extrusion block 21, the anti-sticking agent in the feed groove 19 flows upward and enters the flow groove 46 along the infusion groove 16 and the hose 17. The anti-sticking agent entering the flow groove 46 is absorbed by the sponge 12. When the cutter 7 passes downward through the sleeve 9, the sponge 12 applies the anti-sticking agent to the outer wall of the cutter 7, preventing the cutter 7 from sticking to the sandpaper masterbatch. When the material is cut, adhesive residue adheres to the surface. When the sleeve 5 rotates, it drives the fixing plate 23 to rotate on the turntable 24. The anti-slip pad 25 keeps the turntable 24 stationary, thus preventing wear on the surface of the sandpaper masterbatch when the sleeve 5 rotates. As the support plate 3 moves downward, it drives the two L-shaped brackets 47 downward, causing the mounting ring 39 to move downward, which in turn drives the locking block 41 downward. When the locking block 41 presses against the fixing ring 38, the fixing ring 38 pushes the inclined surface at the bottom of the locking block 41, causing the locking block 41 to move and press the fifth spring 40. When the locking block 41 passes through the fixing ring 38, it returns to its original position under the action of the fifth spring 40. After completing the cutting of a circular piece of sandpaper, the sleeve 5 is retracted upward by the hydraulic cylinder 2. After the sandpaper masterbatch is no longer compressed,Under the action of the second spring 22, the top rod 18 moves downward, causing the feed trough 19 to move downward, facilitating the re-accumulation of anti-sticking agent. Simultaneously, the support plate 3 moves upward, causing the two L-shaped brackets 47 to move upward, which in turn causes the mounting ring 39 to move upward, and the locking block 41 to move upward. At this time, the straight surface at the top of the locking block 41 hooks onto the fixing ring 38. Under the pull of the locking block 41, the fixing ring 38 moves upward, causing the connecting shaft 35 to move upward, which in turn causes the top ring 34 to move upward. The upward push of the top ring 34 helps separate the ring-cut circular sandpaper from the sandpaper masterbatch, facilitating material removal. Furthermore, the top ring 34 can lift the ring-cut circular sandpaper in one go, preventing the circular sandpaper from... As the edge of the shaped sandpaper wrinkles, the connecting shaft 35 moves upward, causing the sliding plate 36 to move upward as well, pressing the fourth spring 37. As the support plate 3 continues to move upward, the top plate 43 inserts into the mounting ring 39 through the through slot and presses against the inclined groove 42 on the top of the locking block 41. Under the action of the top plate 43, the locking block 41 is pushed to move, pressing the fifth spring 40 again. After the locking block 41 moves, it separates from the fixing ring 38, losing its pulling force. Under the action of the fourth spring 37, the connecting shaft 35 and the top ring 34 move downward and reset, facilitating the feeding of the next round sandpaper. This process repeats, preventing the round sandpaper from sticking to the sandpaper masterbatch after ring cutting and being difficult to remove.
