[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the sharpness of the cutting blade in the practical application will decrease after a long period of continuous cutting, and the blade should be polished and maintained at this time. The above-mentioned slitting machine needs to disassemble the cutting blade for polishing, and then reinstall the polished cutting blade, which is inconvenient to operate, and therefore needs to be improved. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a high-gloss water-based resin packaging paper slitting machine.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A high-gloss water-based resin packaging paper slitting machine comprises a workbench, a conveying steel mesh for conveying the packaging paper to be cut is arranged on the top of the workbench, a width cutting assembly for cutting the packaging paper in the width direction is arranged above the workbench, the width cutting assembly comprises a first connecting block arranged above the workbench, a second connecting block arranged above the workbench and corresponding to the position of the first connecting block, a rotating motor fixed on the side wall of one side of the second connecting block, a rotating shaft rotatably installed between the first connecting block and the second connecting block, and a circular blade sleeved on the rotating shaft, the output shaft end of the rotating motor passes through the second connecting block and is fixed to the end of the rotating shaft, the workbench is also provided with a lifting assembly for driving the width cutting assembly to rise and fall, a grinding assembly for grinding the circular blade, a pressure roller assembly for fixing the packaging paper, and a length cutting assembly for cutting the packaging paper in the length direction.

[0008] By adopting the above technical solution, when it is necessary to cut the packaging paper, the staff will place the packaging paper to be cut on the conveying steel mesh on the workbench. After the conveying steel mesh works, it will drive the packaging paper to be cut to move. The pressure roller assembly will press and fix the packaging paper to be cut. At the same time, the packaging paper can move forward under the action of the conveying steel mesh, which is conducive to reducing the probability of displacement of the packaging paper during the cutting process. After starting the rotating motor, the rotating motor drives the rotating shaft to rotate after working, so that the circular blade rotates around the axis of the rotating shaft to complete the cutting work in the width direction of the packaging paper. Then, the length cutting assembly cuts the packaging paper that has been cut in the width direction in the length direction, thereby completing the cutting work of the packaging paper. The circular blade will be blunted after being used for a period of time. At this time, the lifting assembly is started to raise the circular blade to a position close to the grinding assembly. The staff starts the rotating motor. After the rotating motor works, it drives the rotating shaft to rotate, so that the blade of the circular blade remains sharp under the grinding of the grinding assembly, which changes the cumbersome operation of disassembling, grinding and reinstalling the circular blade in the traditional process.

[0009] Furthermore, the lifting assembly includes a lifting motor fixed to the top of the workbench, a threaded rod fixed to the end of the output shaft of the lifting motor, and a guide rod fixedly connected to the top of the workbench, the threaded rod and the guide rod are arranged parallel to each other, the first connecting block is sleeved on the threaded rod and threadedly connected to the threaded rod, and the second connecting block is sleeved on the guide rod and slidably cooperates with the guide rod.

[0010] By adopting the above technical solution, the staff starts the lifting motor, and the lifting motor drives the threaded rod to rotate after it starts working. Since the threaded rod is threadedly connected to the first connecting block, the guide rod is slidingly matched with the second connecting block, and the rotating shaft is rotatably installed between the first connecting block and the second connecting block, the circumferential rotation of the rotating shaft around the threaded rod is limited, so that the rotating shaft can move up and down in the vertical direction, which is conducive to adjusting the circular blade to cut packaging paper of different thicknesses in the width direction, and when the circular blade needs to be polished, the height of the circular blade is adjusted and the polishing work is performed.

[0011] Furthermore, the grinding assembly includes a first mounting frame fixed to the top of the workbench, a mounting block arranged at the bottom of the first mounting frame, and a grinding piece fixed to the bottom of the mounting block. The first mounting frame is penetrated by a fastening bolt that is loosely matched with the first mounting frame. The fastening bolt penetrates the mounting block and is loosely matched with the mounting block. A fastening nut is threadedly connected to the end of the fastening bolt. The grinding piece corresponds to the position of the circular blade, and a first arc-shaped groove that is loosely matched with the top of the circular blade is provided at the bottom of the grinding piece.

[0012] By adopting the above technical solution, the fastening bolts and the fastening nuts cooperate to facilitate the staff to detachably connect the grinding piece to the first mounting frame. The staff starts the lifting motor, and the lifting motor drives the rotating shaft and the circular blade to rise to a position close to the bottom of the grinding piece. After the top of the circular blade fits into the first arc-shaped groove opened at the bottom of the grinding piece, the staff turns off the lifting motor and starts the rotating motor. After the rotating motor works, it drives the rotating shaft to rotate, so that the circular blade is polished under the grinding of the grinding piece to improve the sharpness of the circular blade.

[0013] Furthermore, the rotating shaft is provided with scale lines, and the circular blade is connected to the rotating shaft via a detachable component.

[0014] By adopting the above technical solution, the detachable component makes it easy for the staff to install the circular blade on the rotating shaft. At the same time, the scale lines also make it easy for the staff to accurately adjust the distance between the circular blades, which is conducive to cutting packaging paper of different widths.

[0015] Furthermore, a slide groove is provided through the rotating shaft, and the detachable component includes a sleeve fixed to one side of the circular blade, a disassembly bolt provided through the sleeve and loosely matched with the sleeve, and a disassembly nut threadedly connected to the end of the disassembly bolt, and the disassembly bolt is slidably matched with the slide groove.

[0016] By adopting the above technical solution, when it is necessary to adjust the distance between the two circular blades, the staff loosens the disassembly nut to release the limit on the circular blade, so that the disassembly bolt slides in the slide groove opened on the rotating shaft, and the circular blade and sleeve move synchronously with the disassembly bolt. After adjusting to the required position with the scale line, the staff tightens the disassembly nut, which is conducive to the circular blade cutting packaging paper of different widths.

[0017] Furthermore, the pressure roller assembly includes a gantry fixed to the top of the workbench, a sleeve fixed to the bottom of the gantry, a compression spring fixed to the inner top wall of the sleeve, a sliding rod fixed to the lower end of the compression spring and slidingly matched with the sleeve, and a pressure roller rotatably installed on the sliding rod. The sleeve, the compression spring and the sliding rod are each provided with two and symmetrically arranged at both ends of the pressure roller, and the two ends of the pressure roller are respectively rotatably connected to the two sliding rods.

[0018] By adopting the above technical solution, the pressing roller can limit the packaging paper of different thicknesses under the cooperation of the slide rod, the pressing spring and the sleeve, which is beneficial to improve the stability of the packaging paper during the cutting process. When the conveying steel mesh conveys the packaging paper, the bottom surface of the pressing roller rolls with the top of the packaging paper, which can limit the packaging paper in the vertical direction without affecting the forward movement of the packaging paper.

[0019] Furthermore, the length cutting assembly includes a second mounting bracket fixed to the top of the workbench, a cylinder fixed to the bottom of the second mounting bracket, a cutting frame fixed to the lower end of the piston rod of the cylinder, and a cutting blade detachably mounted on the cutting frame.

[0020] By adopting the above technical solution, the conveyor steel belt transfers the packaging paper that has been cut in the width direction to just below the length cutting component. The staff starts the cylinder, and the cylinder pushes the cutting knife frame and the cutting blade at the lower end of the piston rod, thereby completing the cutting of the packaging paper in the length direction, which is beneficial for the slitting machine to cut out packaging paper of different lengths.

[0021] Furthermore, the grinding assembly includes a mounting plate fixed to the bottom of the first mounting frame and an L-shaped plate detachably connected to the bottom of the first mounting frame by a first bolt and parallel to the mounting plate. The grinding assembly also includes a grinding disc arranged between the mounting plate and the L-shaped plate. The cross-section of the grinding disc is square, and the four side walls of the grinding disc are each provided with a second arc-shaped groove that cooperates with a circular blade. The L-shaped plate is provided with a fixing assembly for fixing the grinding disc.

[0022] By adopting the above technical solution, when one of the second arc-shaped grooves of the grinding disc is no longer able to sharpen the passivated circular blade after multiple grinding, the staff can adjust the fixing component to release the fixation of the grinding disc, rotate the grinding disc 90°, and use the fixing component to fix the grinding disc again, so that the second arc-shaped groove on the other side can grind the circular blade, which is conducive to reducing the frequency of replacing the grinding disc.

[0023] Furthermore, the fixing assembly includes a round rod that is penetrated and arranged on the mounting plate and the L-shaped plate and rotatably cooperates with the mounting plate and the L-shaped plate, a rectangular rod that is fixedly sleeved on the round rod and located between the mounting plate and the L-shaped plate, a handwheel fixedly connected to one end of the round rod, a U-shaped plate fixed on the side wall of the L-shaped plate on the side away from the handwheel, a spring fixed on the side wall of the U-shaped plate on the side away from the mounting plate, a limiting plate fixed to the end of the spring away from the mounting plate, and a rectangular block that is penetrated and arranged on the U-shaped plate and slidably cooperates with the U-shaped plate, the rectangular rod is penetrated and arranged on the polishing piece and slidably cooperates with the polishing piece, a rectangular groove that is plug-in cooperates with the rectangular block is opened on the side of the round rod close to the rectangular block, the side of the handwheel close to the limiting plate is in contact with one of the side walls of the rectangular plates, and the spring is sleeved on the rectangular block.

[0024] By adopting the above technical solution, when the grinding disc needs to be adjusted, the staff needs to pull the limit plate in the opposite direction of the handwheel, driving the spring and the rectangular block away from the U-shaped plate, so that the rectangular block is away from the rectangular groove opened on one side of the round rod. After releasing the limit on the grinding disc, the staff turns the handwheel to a 90° position, driving the round rod, rectangular rod, grinding disc and rectangular groove to rotate 90° synchronously. At this time, the staff releases the limit plate. Since the spring is elastic, under the action of the elastic force of the spring, the rectangular block is driven to be inserted into the rectangular groove again, completing the limit on the grinding disc, which is beneficial to improve the stability of the grinding disc during the grinding process.

[0025] In summary, the utility model has the following beneficial effects:

[0026] 1. In the present application, when it is necessary to cut the wrapping paper, the staff will place the wrapping paper to be cut on the conveying steel mesh on the workbench. After the conveying steel mesh is working, it will drive the wrapping paper to be cut to move. The pressure roller assembly will press and fix the wrapping paper to be cut. At the same time, the wrapping paper can move forward under the action of the conveying steel mesh, which is beneficial to reduce the probability of displacement of the wrapping paper during the cutting process. After starting the rotating motor, the rotating motor will drive the rotating shaft to rotate after working, so that the circular blade rotates around the axis of the rotating shaft to complete the cutting work in the width direction of the wrapping paper. Then, the length cutting assembly will cut the wrapping paper that has been cut in the width direction in the length direction through the length cutting assembly, thereby completing the cutting work of the wrapping paper. The circular blade will become blunt after being used for a period of time. At this time, the lifting assembly is started to raise the circular blade to a position close to the grinding assembly. The staff starts the rotating motor. After the rotating motor is working, it drives the rotating shaft to rotate, so that the blade of the circular blade remains sharp under the grinding of the grinding assembly, which changes the cumbersome operation of disassembling, grinding and reinstalling the circular blade in the traditional process;

[0027] 2. In the present application, the fastening bolt and the fastening nut cooperate to facilitate the staff to detachably connect the grinding piece to the first mounting frame. The staff starts the lifting motor, and the lifting motor drives the rotating shaft and the circular blade to rise to a position close to the bottom of the grinding piece. After the top of the circular blade fits into the first arc-shaped groove opened at the bottom of the grinding piece, the staff turns off the lifting motor and starts the rotating motor. After the rotating motor works, it drives the rotating shaft to rotate, so that the circular blade is polished under the grinding of the grinding piece to improve the sharpness of the circular blade;

[0028] 3. In the present application, when one of the second arc-shaped grooves of the grinding disc is no longer capable of sharpening the passivated circular blade after multiple grinding, the staff adjusts the fixing component to release the fixation of the grinding disc, rotates the grinding disc 90°, and re-fixes the grinding disc with the fixing component, so that the second arc-shaped groove on the other side can grind the circular blade, which is conducive to reducing the frequency of replacing the grinding disc.

In this embodiment, when it is necessary to cut the wrapping paper, the staff places the wrapping paper to be cut on the conveying steel mesh 11 on the workbench 1. The conveying steel mesh 11 will drive the wrapping paper to be cut to move after it starts working. The rotating motor 23 will drive the rotating shaft to rotate after it starts working, so that the circular blade 25 rotates around the axis of the rotating shaft to complete the cutting work in the width direction of the wrapping paper. Subsequently, the wrapping paper that has been cut in the width direction is cut in the length direction through the length cutting component 6, thereby completing the cutting work of the wrapping paper.

[0043] The lifting assembly 3 is arranged on the workbench 1, and is used to drive the width cutting assembly 2 to rise and fall. The lifting assembly 3 includes a lifting motor 31, a threaded rod 32, and a guide rod 33.

The first connecting block 21 is sleeved on the threaded rod 32 and is threadedly connected to the threaded rod 32, and the second connecting block 22 is sleeved on the guide rod 33 and is slidably matched with the guide rod 33. In this embodiment, the staff starts the lifting motor 31, and the lifting motor 31 drives the threaded rod 32 to rotate after it starts working. Since the threaded rod 32 is threadedly connected to the first connecting block 21, the guide rod 33 is slidably matched with the second connecting block 22, and the rotating shaft 24 is rotatably installed between the first connecting block 21 and the second connecting block 22, the circumferential rotation of the rotating shaft 24 around the threaded rod 32 is limited, so that the rotating shaft 24 can move up and down in the vertical direction, which is conducive to adjusting the circular blade 25 to cut packaging paper of different thicknesses in the width direction, and when the circular blade 25 needs to be polished, the height of the circular blade 25 is adjusted and the polishing work is performed.

[0044] The grinding assembly 4 is arranged on the workbench 1 and is used to grind the circular blade 25. The grinding assembly 4 includes a first mounting frame 41, a mounting block 42 and a grinding piece 43.

The staff starts the lifting motor 31, and the lifting motor 31 drives the rotating shaft 24 and the circular blade 25 to rise to a position close to the bottom of the grinding piece 43. After the top of the circular blade 25 is attached to the first arc-shaped groove 431 opened at the bottom of the grinding piece 43, the staff turns off the lifting motor 31 and starts the rotating motor 23. After the rotating motor 23 works, it drives the rotating shaft to rotate, so that the circular blade 25 is polished under the grinding of the grinding piece 43 to improve the sharpness of the circular blade 25.

[0045] The pressing roller assembly 5 is arranged on the workbench 1 and is used to fix the packaging paper. The pressing roller assembly 5 includes a gantry 51, a sleeve 52, a compression spring 53, a slide bar 54 and a pressing roller 55.

In this embodiment, the pressing roller 55 can limit the packaging paper of different thicknesses under the cooperation of the slide bar 54, the compression spring 53 and the sleeve 52, which is conducive to improving the stability of the packaging paper during the cutting process. When the conveying steel mesh 11 conveys the packaging paper, the bottom surface of the pressing roller 55 rolls with the top of the packaging paper, which limits the vertical position of the packaging paper without affecting the forward movement of the packaging paper.

[0046] The length cutting assembly 6 is arranged on the workbench 1, and is used for cutting the packaging paper in the length direction. The length cutting assembly 6 includes a second mounting frame 61, a cylinder 62, a cutting knife frame 63 and a cutting blade 64. The second mounting frame 61 is fixed to the top of the workbench 1, and the cylinder 62 is fixed to the bottom of the second mounting frame 61. The cutting knife frame 63 is fixed to the lower end of the piston rod of the cylinder 62, and the cutting blade 64 is detachably mounted on the cutting knife frame 63. In this embodiment, the conveyor steel belt transfers the packaging paper that has been cut in the width direction to the bottom of the length cutting assembly 6, and the staff starts the cylinder 62, and the cylinder 62 pushes the cutting knife frame 63 and the cutting blade 64 at the lower end of the piston rod, thereby completing the cutting of the packaging paper in the length direction, which is conducive to the slitting machine to cut out packaging paper of different lengths.

[0047] A chute 241 is provided through the rotating shaft 24, and a detachable component 7 is provided on the rotating shaft 24 for installing and shifting the circular blade 25.

In this embodiment, when it is necessary to adjust the distance between the two circular blades 25, the staff loosens the disassembly nut 73 to release the limit of the circular blade 25, so that the disassembly bolt 72 slides in the chute 241 provided on the rotating shaft 24, and the circular blade 25 and the sleeve 71 move synchronously with the disassembly bolt 72. After the scale line 242 is adjusted to the desired position, the staff tightens the disassembly nut 73, which is conducive to the circular blade 25 cutting packaging paper of different widths.

[0048] In order to facilitate the slitting machine to cut packaging papers of different widths, a scale line 242 is provided on the rotating shaft 24 , and the scale line 242 facilitates the staff to accurately adjust the distance between the two circular blades 25 .

[0049] The operating principle of a high-gloss water-based resin packaging paper slitting machine in this embodiment is:

[0050] When it is necessary to cut the wrapping paper, the staff will place the wrapping paper to be cut on the conveying steel mesh 11 on the workbench 1. The conveying steel mesh 11 will drive the wrapping paper to be cut to move after it starts working. The pressure roller assembly 5 will press and fix the wrapping paper to be cut. At the same time, the wrapping paper can move forward under the action of the conveying steel mesh 11, which is beneficial to reduce the probability of displacement of the wrapping paper during the cutting process. After starting the rotating motor 23, the rotating motor 23 will drive the rotating shaft to rotate after it starts working, so that the circular blade 25 rotates around the axis of the rotating shaft to complete the cutting work of the wrapping paper in the width direction. Subsequently, the wrapping paper that has been cut in the width direction is cut in the length direction through the length cutting assembly 6, thereby completing the cutting work of the wrapping paper. The circular blade 25 will become blunt after being used for a period of time. At this time, the lifting component 3 is started to raise the circular blade 25 to a position close to the grinding component 4. The staff starts the rotating motor 23. After the rotating motor 23 works, it drives the rotating shaft to rotate, so that the blade of the circular blade 25 remains sharp under the grinding of the grinding component 4, which changes the cumbersome operation of disassembling, grinding and reinstalling the circular blade 25 in the traditional process.

The mounting plate 44 is fixed to the bottom of the first mounting frame 41, and the L-shaped plate 45 is detachably connected to the bottom of the first mounting frame 41 by bolts (the bolts are not shown in the figure) and is parallel to the mounting plate 44. The grinding disc 46 is rotatably mounted between the mounting plate 44 and the L-shaped plate 45. The cross section of the grinding disc 46 is square, and the four side walls of the grinding disc 46 are provided with second arc grooves 461 that cooperate with the circular blade 25.

[0053] In addition, a high-gloss water-based resin packaging paper slitting machine in this embodiment also includes a fixing assembly 8, which is arranged on the L-shaped plate 45 and is used to fix the grinding disc 46. The fixing assembly 8 includes a round rod 81, a rectangular rod 82, a handwheel 83, a U-shaped plate 84, a first spring 85, a limit plate 86 and a rectangular block 87.

In this embodiment, when the grinding disc 46 needs to be adjusted, the staff needs to pull the limit plate 86 in the opposite direction of the handwheel 83, driving the first spring 85 and the rectangular block 87 away from the U-shaped plate 84, so that the rectangular block 87 is away from the rectangular groove 811 opened on one side of the round rod 81. After releasing the limit on the grinding disc 46, the staff turns the handwheel 83 to a 90° position, driving the round rod 81, the rectangular rod 82, the grinding disc 46 and the rectangular groove 811 to rotate synchronously by 90°. At this time, the staff releases the limit plate 86. Since the first spring 85 is elastic, under the action of the elastic force of the first spring 85, the rectangular block 87 is driven to be plugged into the rectangular groove 811 again, completing the limit on the grinding disc 46, which is beneficial to improving the stability of the grinding disc 46 during the grinding process.
