Description

Technical Field

[0001] This invention relates to a sandpaper slitting machine, and more particularly to a sandpaper slitting machine with adjustable width. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide strips of paper, mica tape, or film into multiple narrow strips. It is commonly used in papermaking machinery, wire and cable mica tape production, and printing and packaging machinery. Slitting machines are mainly used for cutting non-woven fabrics, mica tape, paper, insulating materials, and various film materials, and are particularly suitable for cutting narrow strips (non-woven fabrics, paper, insulating materials, mica tape, film, etc.).

[0003] Sandpaper, also known as abrasive paper, is a material used for grinding. It's used to polish surfaces such as metal and wood to make them smooth and shiny. It's typically made by attaching various abrasive grains to a base paper. Depending on the abrasive material, there are various types, including diamond sandpaper, synthetic diamond sandpaper, and glass sandpaper. During the production of sandpaper, a slitting machine is used for cutting.

[0004] Currently, sandpaper slitting machines still have some defects and shortcomings in use. The specific areas that need improvement are as follows:

[0005] 1. The existing sandpaper cutting width is mostly fixed. When producing sandpaper of different widths, it is necessary to equip different width cutting machines, which increases the equipment investment cost.

[0006] 2. Existing sandpaper slitting machines have a relatively simple slitting mode, making it inconvenient to use other slitting methods when different types of slitting are required.

[0007] 3. Existing sandpaper cutting extrusion systems do not have automatic processing and collection capabilities for the cut sandpaper, thus reducing the automation of cutting operations;

[0008] 4. Existing sandpaper slitting machines are not convenient for placing and removing the winding drum used for collection, thus reducing the collection effect after slitting;

[0009] 5. Existing sandpaper slitting machines do not have a convenient clamping and lifting function to prevent interference with the slitting operation of roll products that need to be slitting. Summary of the Invention

Detailed Implementation

[0039] 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.

[0040] Please see Figures 1-10This invention provides a technical solution for a sandpaper slitting machine with adjustable width: it includes a support platform 1, on which a linkage 2 and a clamping component 5 are provided. The linkage 2 is connected to a retracting component 3 and a cutting component 4. Four first fixing plates 6 are fixedly provided on the support platform 1. The four first fixing plates 6 are respectively fixedly connected to four clamping shafts 7. The four clamping shafts 7 are divided into two groups, and the two groups are respectively connected to the retracting component 3 and the cutting component 4. A clamping wheel group 10 and an inclined frame 8 are fixedly provided on the support platform 1. The inclined frame 8 and the linkage 2 correspond to the material feeding hole opened on the support platform 1. A controller 9 is installed on the first fixing plate 6 on the front side. The controller 9 has an automatic control program, and the output end of the automatic control program is electrically connected to the input ends of the first motor 29, the second motor 256, the third motor 35, the fourth motor 44, the fifth motor 55, the first electric push rod 211, the second electric push rod 2310, the third electric push rod 244, and the fourth electric push rod 53.

[0041] The linkage component 2 includes two loop plates 21. The four corners of the two loop plates 21 are fixedly connected to four first connecting plates 22. A cutting component 23 and a disassembly component 25 are provided between the two loop plates 21. The upper left first connecting plate 22 is connected to the cutting component 24. The two loop plates 21 are rotatably connected to two locking wheels 27 and overlapping wheels 212 via three sets of bearings. The two locking wheels 27 are fixedly connected to two gears 28. The two gears 28 mesh with each other, so that when the two gears 28 mesh and rotate, they drive the two locking wheels 27 to rotate relative to each other, thus pulling out the sandpaper and achieving the output driving effect. The front end of the upper locking wheel 27 is fixedly connected to the output shaft of the first motor 29. The first motor 29 is mounted on the front loop plate 21 and is a servo motor with a timed rotation mode and a continuous rotation mode. A second connecting plate 210 and a flat baffle 2 are fixedly provided between the two loop plates 21. 6. The second connecting plate 210 is fixedly connected to the output end of the first electric push rod 211. The first electric push rod 211 is installed on the support platform 1. The sandpaper passes through the clamping wheel assembly 10 and the two clamping wheels 27 on the linkage 2. Then, the controller 9 controls the first motor 29 on the linkage 2 to rotate at a time, so that the first motor 29 drives the two clamping wheels 27 to rotate relative to each other, thereby driving the clamping wheels 27 to extend the sandpaper and place it on the multi-groove plate 251 on the removal part 25. In this way, the first motor 29 can output a certain length of sandpaper. The controller 9 controls the first electric push rod 211 on the linkage 2 to extend. The first electric push rod 211 drives the second connecting plate 210 and the two spiral plates 21 to move upward synchronously, thereby causing the two spiral plates 21 to move upward and drive the flipping cutter 4 and the flipping collection part 3 to rotate downward, thereby causing the multiple adjusting cutters 45 on the flipping cutter 4 to descend synchronously and causing the cutting disc 452 to press against the sandpaper for cutting operation.

[0042] The slitting piece 23 includes a first fixed slot plate 231, on which multiple first positioning slots are formed. Multiple sliding frames 232 are fitted onto the first fixed slot plate 231. Each sliding frame 232 has a first frame 233 fixedly connected to its side. Each first frame 233 has a first retaining plate 234 fitted inside it. The first retaining plates 234 are respectively fitted onto the sliding frames 232. Each first retaining plate 234 is adapted to the first positioning slots on the first fixed slot plate 231. The first retaining plates 234 are respectively fixedly connected to multiple push plates 235. Each push plate 235 has one end fixedly connected to two first springs 236. The other ends of the two first springs 236 are... It is fixedly connected to any one of the sliding frames 232. By pulling the push plate 235 on the slitting piece 23, the push plate 235 causes the first slot plate 234 to disengage from the first positioning groove on the first fixed groove plate 231. At the same time, the push plate 235 drives the two first springs 236 to stretch and generate elastic tension. Then, the slitting piece 23 can be pushed to slide along the first fixed groove plate 231, so that the first cutting edge 237 on the slitting piece 23 slides to the required adjustment position. The push plate 235 is released, and the first springs 236 drive the push plate 235 and the first slot plate 234 to be locked into the corresponding first positioning groove to restrict the sliding. In this way, other slitting pieces 23 can be adjusted to slide to the corresponding sliding width requirements.

[0043] Each of the multiple sliding frames 232 is fixed with a first cutting blade 237 and a second frame 238. The multiple second frames 238 are all sleeved with a linkage plate 239. The linkage plate 239 is fixedly connected to the extended end of the second electric push rod 2310. The second electric push rod 2310 is installed on the first fixed groove plate 231. The first fixed groove plate 231 is fixed between two U-shaped plates 21. The controller 9 controls the second electric push rod 2310 on the slitting piece 23 to retract. The second electric push rod 2310 drives the linkage plate 239 to descend synchronously, so that the linkage plate 239 drives the second frames 238 on the multiple slitting pieces 23 and the slitting pieces 23 as a whole to slide down. In this way, the multiple descending slitting pieces 23 can synchronously drive the first cutting blade 237 to perform width positioning and slitting on the cut sandpaper. Then, the second electric push rod 2310 is controlled to retract and drive the first cutting blade 237 to move up and reset.

[0044] The cutting component 24 includes a first set of sliding plates 241, on which a second cutting blade 242 is fixed. The second cutting blade 242 is perpendicular to multiple first cutting blades 237. Two inner sleeve plates 243 are respectively fitted at both ends of the first set of sliding plates 241. The two inner sleeve plates 243 are respectively fixed between the upper and lower sides inside the two U-shaped plates 21. The first set of sliding plates 241 is fixedly connected to the extended end of the third electric push rod 244. The third electric push rod 244 is installed on the first connecting plate 22 on the upper left side. The controller 9 controls the extension of the third electric push rod 244 on the cutting component 24. The third electric push rod 244 drives the first set of sliding plates 241 and the second cutting blade 242 to descend synchronously, so that the second cutting blade 242 cuts the sandpaper on the multi-groove plate 251. Then, the controller controls the third electric push rod 244 to retract and drive the second cutting blade 242 to move upward and reset.

[0045] The disengagement component 25 includes a multi-groove plate 251. The front and rear ends of the multi-groove plate 251 are respectively fitted with first movable holes opened on two U-shaped plates 21. The multi-groove plate 251 has multiple grooves, which correspond vertically to multiple first positioning grooves on the first fixed groove plate 231. The front and rear sides of the multi-groove plate 251 are respectively fixedly connected to two movable plates 252. The two movable plates 252 are respectively threadedly connected to two lead screws 253. The two lead screws 253 are rotatably connected to two second fixed plates 254 through bearings. The four second fixed plates 254 are divided into two groups, and the two groups are respectively fixedly connected to opposite sides of the two U-shaped plates 21. The two lead screws 253 are mutually driven through a pulley group 255. The end of the rear lead screw 253 is connected to the second motor 25. The output shaft of 6 is fixedly connected. The second motor 256 is installed on the rear U-shaped plate 21. The multi-groove plate 251 and the flat baffle 26 are horizontally offset. The second motor 256 on the control disengagement component 25 is started. The second motor 256 drives the two lead screws 253 to rotate synchronously through the pulley group 255. The rotating lead screws 253 drive the two moving plates 252 and the multi-groove plate 251 to move. The moving multi-groove plate 251 drives the slit sandpaper to move synchronously and block the flat baffle 26. The sandpaper slides off the multi-groove plate 251 and falls into the inclined frame 8 through the material discharge hole on the support platform 1 for collection. The disengagement component 25 can be controlled to reset and the sandpaper can be continuously slit.

[0046] The flipping component 3 includes two first flipping plates 31, which are fixedly connected to two first rotating shafts 32. The two first rotating shafts 32 are rotatably connected to the upper right ends of two U-shaped plates 21 via bearings. The two first flipping plates 31 are respectively sleeved with two right-side retaining shafts 7 through two second movable holes. One of the first flipping plates 31 is movably connected to a second flipping plate 33 via a hinge seat. The second flipping plate 33 is rotatably connected to a first horizontal shaft fixed on a sleeve plate 34 via bearings, and the end of the first horizontal shaft is fixedly connected to the output shaft of a third motor 35. The third motor 35 is mounted on the second flipping plate 33. A positioning disc 36 is fixedly provided on the sleeve plate 34, allowing the positioning disc 36 to contact and abut against the other first flipping plate 31, thereby... After the second rotating shaft 37 is fitted with the U-shaped hole, it forms a support and positioning restriction for the sleeve plate 34. The positioning disk 36 is rotatably connected to the second rotating shaft 37 through the bearing. The second rotating shaft 37 is adapted to the U-shaped hole opened on another first flip plate 31. One of the first flip plates 31 is fixed with a positioning plate 38 corresponding to the second flip plate 33, which can position and block the flipping of the second flip plate 33, thereby providing parallel support for the sleeve plate 34. The slit sandpaper is wrapped around the overlapping wheel 212 and wound around the multiple winding wheels fitted on the flipping and collecting component 3. Then, the third motor 35 on the flipping and collecting component 3 is started, so that the third motor 35 drives the sleeve plate 34 and multiple winding drums to wind and collect the slit sandpaper. In this way, the sandpaper can be slit and collected.

[0047] The cutting component 4 includes two third flip plates 41, which are fixedly connected to two third rotating shafts 42. The two third rotating shafts 42 are rotatably connected to the upper left ends of two U-shaped plates 21 via bearings. The two third flip plates 41 are sleeved with two retaining shafts 7 on the left side via third movable holes. Both third flip plates 41 are rotatably connected to a second horizontal shaft fixed on the transmission plate 43, and the second horizontal shaft is fixedly connected to the output shaft of a fourth motor 44. The fourth motor 44 is mounted on one of the third flip plates 41. The transmission plate 43 is provided with multiple cutting adjustment components 45, which are all connected to a second fixed slot plate 46. The second fixed slot plate 46 is n-shaped and has multiple second positioning slots. The two side plates of the second fixed slot plate 46 are respectively connected to the two third flip plates 41. The fixed connection allows the first motor 29 on the linkage 2 to rotate continuously, while simultaneously controlling the fourth motor 44 on the cutting component 4 to start. This causes the rotating first motor 29 to drive the card wheel 27 to rotate the sandpaper, while the fourth motor 44 drives the cutting discs 452 on multiple cutting components 45 to rotate synchronously. This allows the moving sandpaper to be cut by multiple cutting discs 452. With the drive of the first motor 29, the cut sandpaper is pulled out, allowing it to wrap around the overlapping wheel 212 and be wound around the multiple winding wheels on the collecting component 3. Then, the third motor 35 on the collecting component 3 is started, causing the third motor 35 to drive the sleeve plate 34 and multiple winding drums to wind and collect the cut sandpaper. This allows for the cutting and collection of sandpaper.

[0048] Multiple cutting components 45 each include a drive shaft 451, which is sleeved on a drive plate 43 and fixedly connected to a cutting disc 452. The drive shaft 451 is rotatably connected to a push plate 453 via bearings. The push plate 453 is sleeved with a second fixed slot plate 46 through a fourth movable hole. A third frame 454 and a third fixed plate 457 are fixedly mounted on the push plate 453. A second slot plate 455 is sleeved inside the third frame 454 and is adapted to any one of the second positioning slots. The second slot plate 455 is L-shaped and fixedly connected to the upper ends of the two second springs 456. The lower ends of the two second springs 456 are fixedly connected to the third fixing plate 457. By pulling the second slot plate 455 on the adjusting piece 45 downward and squeezing the second springs 456, the second slot plate 455 also disengages from the second positioning groove on the second fixing plate 46. Then, the entire adjusting piece 45 can be pushed to slide and adjust the distance between it and other adjusting pieces 45, thereby adjusting its width.

[0049] The clamping component 5 includes two track plates 51 and two insert plates 54. Both track plates 51 are n-shaped and fixedly connected to the support platform 1. The two track plates 51 are respectively fitted with two second slide plates 52. The bottom surfaces of the two second slide plates 52 are respectively fixedly connected to the protruding ends of two fourth electric push rods 53. The two fourth electric push rods 53 are installed on the support platform 1. One of the second slide plates 52 is rotatably connected to one of the insert plates 54 through a bearing. One of the insert plates 54 is fixedly connected to the output shaft of the fifth motor 55. The fifth motor 55 is installed on one of the second slide plates 52. By controlling the fifth motor 55 to start, the fifth motor 55 can drive the clamped sandpaper roll to rotate, thereby avoiding the large weight of the sandpaper when it rotates, which makes it difficult to rotate on its own and tear the sandpaper. This also facilitates the continuous output supply of sandpaper for the slitting operation.

[0050] Another second set of slide plates 52 is sleeved with an n-shaped push-pull plate 56. The push-pull plate 56 is threadedly connected to a threaded rod 58. The threaded rod 58 is rotatably connected to another second set of slide plates 52. The push-pull plate 56 is fixedly connected to a third connecting plate 57. The third connecting plate 57 is rotatably connected to another sleeve plate 54 through a bearing. By rotating the threaded rod 58, one of the sleeve plates 54 on the third connecting plate 57 is driven to insert into the sleeve on the sandpaper roll, and at the same time, it is pushed to insert into the other sleeve plate 54. Then, the controller 9 controls the two fourth electric push rods 53 on the clamping part 5 to extend. The two fourth electric push rods 53 drive the two second set of slide plates 52 to slide upward along the rail plate 51, thereby driving the clamped sandpaper roll to rise synchronously, which facilitates the rotation output of sandpaper.

[0051] The operation steps of this invention are as follows:

[0052] Place the sandpaper rolls to be cut on the support platform 1 at the corresponding position of the clamping piece 5. Then, rotate the threaded rod 58 to drive one of the sleeve plates 54 on the third connecting plate 57 to insert into the sleeve on the sandpaper roll. At the same time, push it to insert into the other sleeve plate 54 as well. Then, control the controller 9 to extend the two fourth electric push rods 53 on the clamping piece 5. The two fourth electric push rods 53 drive the two second sliding plates 52 to slide upward along the track plate 51, thereby driving the clamped sandpaper rolls to rise synchronously, which facilitates the rotation operation. Then, pull the push plate 2 on the cutting piece 23. 35. The push plate 235 causes the first slot plate 234 to disengage from the first positioning slot on the first fixed slot plate 231. At the same time, the push plate 235 causes the two first springs 236 to be stretched to generate elastic tension. Then, the slitting piece 23 can be pushed to slide along the first fixed slot plate 231, so that the first cutting edge 237 on the slitting piece 23 slides to the required adjustment position. The push plate 235 is released, and the first springs 236 cause the push plate 235 and the first slot plate 234 to be locked into the corresponding first positioning slot to restrict the sliding. In this way, other slitting pieces 23 can be adjusted to slide to the corresponding slitting width requirements.

[0053] The sandpaper is then passed through the clamping wheel assembly 10 and the two clamping rollers 27 on the linkage 2. The controller 9 then controls the first motor 29 on the linkage 2 to rotate periodically, causing the first motor 29 to drive the two clamping rollers 27 to rotate relative to each other. This causes the clamping rollers 27 to extend the sandpaper and place it on the multi-groove plate 251 on the disengagement component 25. This allows the first motor 29 to output a certain length of sandpaper. Then, the controller 9 controls the third electric push rod 244 on the cutting component 24 to extend. The third electric push rod 244 drives the first sliding plate 241 and the second cutting blade 242 to descend synchronously, thus causing the second cutting blade 24... 2. The sandpaper placed on the multi-groove plate 251 is cut. Then, the third electric push rod 244 is controlled to retract and drive the second cutting blade 242 to move up and reset. Then, the controller 9 controls the second electric push rod 2310 on the slitting piece 23 to retract. The second electric push rod 2310 drives the linkage plate 239 to descend synchronously, so that the linkage plate 239 drives the second frame 238 on multiple slitting pieces 23 and the slitting pieces 23 as a whole to slide down. In this way, multiple descending slitting pieces 23 can synchronously drive the first cutting blade 237 to perform width positioning and slitting on the cut sandpaper. Then, the second electric push rod 2310 is controlled to retract and drive the first cutting blade 237 to move up and reset.

[0054] Then, the second motor 256 on the control unit 25 is started. The second motor 256 drives the two lead screws 253 to rotate synchronously through the pulley group 255. This causes the two rotating lead screws 253 to move the two moving plates 252 and the multi-groove plate 251. This causes the moving multi-groove plate 251 to move the slit sandpaper synchronously and block the flat baffle 26. This causes the sandpaper to slide off the multi-groove plate 251. In this way, the sandpaper can fall off the multi-groove plate 251 and drop into the inclined frame 8 through the material discharge hole on the support table 1 for collection. This allows the control unit 25 to be reset, and the sandpaper can be continuously slit.

[0055] When other types of cutting operations are required, the second slot plate 455 on the cutting adjustment piece 45 can be pulled down and the second spring 456 can be squeezed. At the same time, the second slot plate 455 also disengages from the second positioning slot on the second fixed slot plate 46. Then, the entire cutting adjustment piece 45 can be pushed to slide and adjust the distance between it and other cutting adjustment pieces 45, thereby adjusting its width. In this way, other cutting adjustment pieces 45 can be adjusted synchronously to meet the width adjustment requirements. Then, the controller 9 controls the first electric push rod 211 on the linkage piece 2 to extend. The first electric push rod 211 drives the second connecting plate 210 and the two spiral plates 21 to move up synchronously, thereby causing the two spiral plates 21 to move up and drive the flipping cutting piece 4 and the flipping collecting piece 3 to rotate down, thereby causing the multiple cutting adjustment pieces 45 on the flipping cutting piece 4 to descend synchronously and the cutting disc 452 to press against the sandpaper.

[0056] Then, the first motor 29 on the linkage 2 can be controlled to rotate continuously, and the fourth motor 44 on the flipping and cutting part 4 can be started at the same time. In this way, the rotating first motor 29 drives the carding wheel 27 to rotate the sandpaper. At the same time, the fourth motor 44 drives the cutting discs 452 on multiple adjusting cutting parts 45 to rotate synchronously. In this way, the moving sandpaper can be cut by multiple cutting discs 452. At the same time, with the drive of the first motor 29, the cut sandpaper is pulled out. In this way, the cut sandpaper can be wrapped around the overlapping wheel 212 and wound around the multiple winding wheels on the flipping and collecting part 3. Then, the third motor 35 on the flipping and collecting part 3 is started, so that the third motor 35 drives the sleeve plate 34 and multiple winding drums to wind and collect the cut sandpaper. In this way, the sandpaper can be cut and collected.

[0057] To remove the take-up drum on the take-up retractor 3, the sleeve plate 34 can be pulled to drive the second flip plate 33 to flip and rotate, which can drive the wound take-up drum to rotate and cause the second rotating shaft 37 to disengage from the U-shaped hole, thus making it easier to remove the take-up drum.
