Description

Technical Field

[0001] The invention relates to the technical field of slitting machines, in particular to an ultra-thin high-speed special paper slitting machine. Background Art

[0002] Specialty paper is a kind of paper with special functions made by using a papermaking machine to make different fibers. There are many kinds of specialty paper, which is a general term for various special-purpose papers or art papers. At present, in order to simplify the confusion caused by the wide variety of terms, people usually refer to art papers such as embossed paper as specialty paper. The specialty paper currently produced in the workshop is large in size and difficult to use directly. Therefore, it needs to be processed by a slitting machine after production. The slitting machine passes the special paper between the blade and the knife seat. During the unwinding and transmission of the special paper, the blade squeezes the knife seat to cut the special paper, so that the special paper is cut into several strips of the expected width.

[0003] The knife seat and blade of the existing slitting machine for processing ultra-thin special paper are both ring-shaped, and several blades and knife seats are fixed on the knife shaft by top screws. When used for cutting special papers of different widths, the distance between adjacent knife seats and blades needs to be adjusted, so the top screws need to be frequently disassembled and assembled. The tightening and disassembly process of the top screws can only rely on manual operation with tools. The number of knife seats and blades is large, which makes the disassembly and assembly of the top screws time-consuming and labor-intensive, affecting the processing efficiency of special paper. In addition, there are currently two ways to adjust the distance between adjacent knife seats and blades: manual adjustment and automatic adjustment. Manual adjustment requires the use of a ruler for distance measurement. There are problems of large errors and slow speed in adjusting the distance by naked eye. Automatic adjustment usually uses a clamping and stacking method, using a clamp to clamp the knife seat or blade, and then moving the knife seat or blade to a specified position on the knife shaft. After loosening, repeat the above operation to place several knife seats or blades at equal distances in sequence. This clamping and stacking distance adjustment method has the problem that the reciprocating activity trajectory of the clamp is too long and the knife seat and blade need to be adjusted in sequence, resulting in a slow adjustment speed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The ultra-thin high-speed special paper slitting machine is provided with a movable block, a vertical rod and a rubber piston. During the distance adjustment process, the telescopic cylinder extends to push the pressure block downward, so that the pressure block squeezes the knife seat or the blade at the bottom. The pressure of the pressure block causes the vertical rod to retract into the telescopic groove. The vertical rod drives the rubber piston to slide in the telescopic groove. The bottom of the vertical rod pushes the movable block to rotate around the first pin shaft, so that the bottom of the movable block squeezes the upper surface of the knife shaft through the toothed protective pad. The squeezing effect of the toothed protective pad limits the movement of the knife seat and the blade relative to the knife shaft, and then the knife seat and the blade are quickly fixed on the knife shaft, so that the slitting machine can press and fix the knife seat and the blade while adjusting the distance, avoiding the trouble of fixing the traditional knife seat and the blade with a top screw.

[0018] The ultra-thin high-speed special paper slitting machine is provided with a pitch adjustment mechanism, and a motor drives a screw to rotate, and the screw drives another screw to rotate through a transmission wheel and a transmission belt. The two screws rotate and drive a slider to slide in a slide groove through a screw hole, so that the two sliders drive the crossbeam to move until the crossbeam moves to the center position between the knife seat and the blade, and the telescopic cylinder is driven by a rodless cylinder to move to just above the knife seat or the blade, and the position of the knife seat or the blade is detected by a distance measuring sensor, and then the telescopic cylinder is extended to push the pressure block downward, and the pressure block squeezes the lower knife seat or blade to fix it, and then the electric telescopic rod is controlled to extend a fixed distance, and the electric telescopic rod drives the push plate to move, and the push plate pushes the adjacent knife seat or blade to a specified position, and the push plate is pushed or toggled along the axis of the knife shaft to achieve the effect of adjusting the distance between the knife seat and the blade. Compared with the traditional clamping and stacking method, this toggle-type adjustment method can reduce the path of the pressure block moving in the direction of the crossbeam, and there is no need to reciprocately clamp the knife seat and the blade.

[0019] This ultra-thin high-speed special paper slitting machine is provided with a pressure block, the bottoms of both ends of the pressure block are arc-shaped depressions, and the pressure block is Z-shaped, so that after the pressure block moves down, the two ends are pressed on the knife seat and the blade respectively, so that the knife seat and the blade can be adjusted at the same time, and the adjustment accuracy of the blade and the knife seat can be kept consistent. Compared with the traditional clamping and stacking type, the adjustment time of the slitting machine can be halved, and the adjustment speed of the slitting machine can be greatly accelerated on the basis of meeting the automatic adjustment.

[0020] This ultra-thin high-speed special paper slitting machine is provided with a top plate and a shifting block. Before adjusting the distance, it is necessary to cancel the fixing effect of the knife seat and the blade on the knife shaft. By shifting the shifting blocks at both ends of the knife shaft downward, the shifting blocks drive the top plate to rotate around the second pin shaft, and the top plate is tilted upward and inserted into the groove, and the movable block is lifted upward to rotate upward around the first pin shaft, thereby pushing the vertical rod to drive the rubber piston to move upward in the telescopic groove, and the vertical rod extends from the top of the knife seat and the blade, canceling the squeezing effect of the movable block on the knife shaft, and realizing the unified disassembly effect of several knife seats and blades on the knife shaft.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figures 1 to 8As shown, the ultra-thin high-speed special paper slitting machine of this embodiment includes a frame 1, a reel 2 installed on one side of the frame 1 and a reel 3 installed on the other side of the frame 1. The number of reel 3 is several, which is used to reel in several strips of special paper after cutting. A knife seat 4 is arranged in the middle of the frame 1, and a blade 5 is arranged on one side of the knife seat 4. A knife shaft 6 is arranged through the middle of the knife seat 4 and the blade 5. The number of knife seats 4 and blades 5 on the knife shaft 6 is several. Slide grooves 7 are provided on the inner walls of both sides of the frame 1 and directly above the knife seat 4. A distance adjustment mechanism 8 is installed between the two slide grooves 7 for automatically adjusting the distance between the knife seat 4 and the blade 5. Guide rollers 9 are installed on the upper and lower sides of the knife seat 4 and the blade 5 inside the frame 1. The number of guide rollers 9 is several and is used to guide the transmission of special paper;

[0034] The knife seat 4 and the blade 5 are both in annular shape, and a groove 41 is provided on the top of the inner wall of the knife seat 4 and the blade 5. A movable block 42 is arranged inside the groove 41. The groove 41 provides sufficient activity space for the movable block 42 to rotate. A first pin shaft 43 is penetrated on one side of the movable block 42. A telescopic groove 44 is provided above the middle of the groove 41. A vertical rod 45 is arranged inside the telescopic groove 44. The vertical rod 45 is in the shape of a round rod. The vertical rod 45 penetrates the telescopic groove 44. A rubber piston 46 is sleeved on the outside of the vertical rod 45. The rubber piston 46 is made of high-elastic rubber to provide sufficient sliding friction between the rubber piston 46 and the inner wall of the telescopic groove 44. The rubber piston 46 is cylindrical and fixed on the outside of the lower half of the vertical rod 45.

[0035] Specifically, a toothed anti-skid pad 47 is laid at the bottom of the movable block 42, and a toothed strip is arranged on the surface of the toothed anti-skid pad 47 to increase the friction between the toothed anti-skid pad 47 and the knife shaft 6. The movable block 42 is in the shape of an arc-shaped plate with one side thick and the other side thin. The movable block 42 is rotatably connected to the inner wall of the groove 41 via the first pin shaft 43, and the bottom of the movable block 42 contacts the outer wall of the knife shaft 6 via the toothed anti-skid pad 47. In the process of the bottom of the movable block 42 being squeezed by the toothed protective pad on the upper surface of the knife shaft 6, the extrusion effect of the toothed protective pad limits the movement of the knife seat 4 and the blade 5 relative to the knife shaft 6, thereby quickly fixing the knife seat 4 and the blade 5 on the knife shaft 6.

[0036] Furthermore, the top of the telescopic groove 44 extends to the upper surface of the knife seat 4 and the blade 5. The telescopic groove 44 is cylindrical, and the bottom of the telescopic groove 44 is connected to the groove 41, so that the vertical rod 45 is inserted into the groove 41 to squeeze the movable block 42. The rubber piston 46 is sleeved on the outer side of the lower half of the vertical rod 45. The vertical rod 45 is slidably connected to the inner wall of the telescopic groove 44 through the rubber piston 46. During the distance adjustment process of the distance adjustment mechanism 8, the pressure block 87 moves down to squeeze the knife seat 4 or the blade 5 at the bottom. The pressure block 87 squeezes the vertical rod 45 back into the telescopic groove 44, and the vertical rod 45 drives the rubber piston 46 to slide in the telescopic groove 44. The bottom of the vertical rod 45 pushes the movable block 42 to rotate around the first pin shaft 43, so that the bottom of the movable block 42 squeezes the upper surface of the knife shaft 6 through the toothed protective pad.

[0037] Furthermore, a movable groove 61 is provided inside the knife shaft 6, and a top plate 62 is arranged inside the movable groove 61. The bottoms of both ends of the top plate 62 are connected to shift blocks 63, and a second pin shaft 64 is arranged through the bottom of the top plate 62. There are two knife shafts 6, and the two knife shafts 6 respectively penetrate the knife seat 4 and the blade 5 and are installed on the frame 1. Both ends of the knife shaft 6 are rotatably connected to the frame 1 through bearings. When the special paper is conveyed, the knife shaft 6, the knife seat 4 and the blade 5 rotate relative to each other. During the distance adjustment process, the two knife shafts 6 do not need to move, that is, the knife seat 4 and the blade 5 can be adjusted in distance in the contact state. The relative clamping and stacking distance adjustment method avoids the trouble of adjusting the relative movement of the two knife shafts 6 to provide additional operating space for the fixture.

[0038] Furthermore, the top plate 62 is in the shape of an arc-shaped long strip, and the second pin shaft 64 is eccentrically arranged in the knife shaft 6. When the top plate 62 rotates around the second pin shaft 64, the top of the top plate 62 will be inserted into the groove 41, gradually pushing the movable plate to move up, and the top plate 62 is rotatably connected to the knife shaft 6 via the second pin shaft 64, and the top of the movable groove 61 is connected to the groove 41. When the top plate 62 rotates around the second pin shaft 64, the top plate 62 is tilted upward and inserted into the groove 41, pushing the movable block 42 upward, so that the movable block 42 rotates upward around the first pin shaft 43, and then pushing the vertical rod 45 to drive the rubber piston 46 to move up in the telescopic groove 44, and the vertical rod 45 extends from the top of the knife seat 4 and the blade 5, canceling the squeezing effect of the movable block 42 on the knife shaft 6, and achieving a unified disassembly effect of several knife seats 4 and blades 5 on the knife shaft 6.

[0039] Furthermore, there are two shift blocks 63, which are symmetrically distributed on the side walls at both ends of the top plate 62. The shift blocks 63 are integrally connected to the top plate 62. The shift blocks 63 are rotatably connected to the knife shaft 6 via the second pin shaft 64. Before adjusting the distance, the fixing effect of the knife seat 4 and the blade 5 on the knife shaft 6 needs to be cancelled. By shifting the shift blocks 63 at both ends of the knife shaft 6 downward, the shift blocks 63 drive the top plate 62 to rotate around the second pin shaft 64.

[0040] Furthermore, the distance adjustment mechanism 8 includes a slider 81, the cross section of the slider 81 is T-shaped, the slider 81 is stuck in the slide slot 7, the number of the sliders 81 is two, a cross beam 82 is connected between the two sliders 81, and the side walls on both sides of the cross beam 82 are embedded with rodless cylinders 83. The two rodless cylinders 83 are connected to the same air source for synchronous driving. Telescopic cylinders 84 are installed on the two rodless cylinders 83. A connecting frame 85 is installed between the two telescopic cylinders 84 at the bottom of the cross beam 82. The connecting frame 85 is also Z-shaped and is used to connect the two telescopic cylinders 84 to ensure that the two telescopic cylinders 84 move synchronously. The side walls of the telescopic cylinders 84 are installed with distance measuring sensors 86 The distance sensor 86 uses a miniature laser distance measurement to detect the distance to the knife shaft 6. When the detected distance data is too close, it means that the pressure block 87 moves to above the knife seat 4 and the blade 5. At this time, the rodless cylinder 83 stops moving. In actual application, the installation position of the distance sensor 86 must be strictly controlled to ensure that when the distance sensor 86 detects the knife seat 4 and the blade 5, the pressure block 87 is just above the knife seat 4 and the blade 5. The bottom of the telescopic cylinder 84 is connected to the pressure block 87, and an electric telescopic rod 88 is arranged inside the pressure block 87. The telescopic end of the electric telescopic rod 88 is connected to a push plate 89, and the electric telescopic rod 88 is used to push the push plate 89 to move.

[0041] Furthermore, the two telescopic cylinders 84 are connected by a connecting frame 85, and the two telescopic cylinders 84 are synchronously moved along the direction of the crossbeam 82 by connecting with the connecting frame 85. The pressure block 87 is in the shape of a Z-shaped plate. The tops of both ends of the pressure block 87 are respectively connected to the telescopic ends of the two telescopic cylinders 84. The bottoms of both ends of the pressure block 87 are in the shape of arcs, and the tops of the knife seat 4 and the blade 5 are in contact with the depressions at the bottom of the pressure block 87. By designing the bottoms of both ends of the pressure block 87 to be arc-shaped depressions and the pressure block 87 to be in a Z shape, the two ends of the pressure block 87 can be pressed on the knife seat 4 and the blade 5 respectively after moving downward, so that the distance of the knife seat 4 and the blade 5 can be adjusted at the same time, and the distance adjustment accuracy of the blade 5 and the knife seat 4 can be kept consistent. Compared with the traditional clamping and stacking method, the distance adjustment time of the slitting machine can be halved, and the distance adjustment speed of the slitting machine can be greatly accelerated on the basis of meeting the automatic distance adjustment.

[0042] Furthermore, a screw hole 811 is provided through the middle of the slider 81, and a screw rod 812 is provided inside the screw hole 811. The outer diameter of the screw rod 812 is matched with the inner diameter of the screw hole 811. A transmission wheel 814 is sleeved on one end of the screw rod 812, and the other end of the screw rod 812 is rotatably connected to the inner wall of the slide groove 7 via a bearing. There are two screw rods 812, and the end of the transmission wheel 814 at one end of one of the screw rods 812 is connected to a motor 813. The motor 813 is essentially an electric motor with a forward and reverse circuit. The shaft end of the motor 813 is connected to a screw rod 812, and a transmission belt 815 is connected between the two transmission wheels 814. The transmission connection between the two transmission wheels 814 is achieved through the transmission belt 815.

[0043] Furthermore, a transmission connection is formed between the two screw rods 812 via a transmission wheel 814 and a transmission belt 815. The screw rod 812 passes through the slider 81 through the screw hole 811. The screw rod 812 and the screw hole 811 form a threaded connection. The slider 81 is stuck in the slide groove 7 to form a sliding connection. The motor 813 drives the screw rod 812 to rotate. The screw 812 drives the other screw rod 812 to rotate via the transmission wheel 814 and the transmission belt 815. The two screw rods 812 rotate and drive the slider 81 to slide in the slide groove 7 via the screw hole 811, so that the two sliders 81 drive the crossbeam 82 to move, so that the crossbeam 82 moves to the center position between the knife seat 4 and the blade 5 when adjusting the distance. During the normal processing of special paper, the crossbeam 82 moves to one side to avoid blocking the transmitted special paper.

[0044] The method of using this embodiment is as follows: when the user actually uses the slitting machine to process special paper, the special paper is unwound from the unwinding roller 2, guided by the guide roller 9 to pass between the knife seat 4 and the blade 5, and as the special paper is transmitted, the blade 5 squeezes the knife seat 4 to cut the special paper into a plurality of strips, and the cut special paper is guided by the guide roller 9 to be rolled up on a plurality of winding rollers 3. When it is necessary to adjust the distance between the knife seat 4 and the blade 5 on the knife shaft 6, the shifting blocks 63 at both ends of the knife shaft 6 are first pushed downward, and the shifting blocks 63 drive the top plate 62 to rotate around the second pin shaft 64, and the top plate 62 is tilted upward and inserted into the groove 41, and the movable block 42 is pushed upward, so that the movable block 42 rotates upward around the first pin shaft 43, and then the vertical rod 45 is pushed to drive the rubber piston 46 in the telescopic groove 44. The vertical rod 45 extends from the top of the knife holder 4 and the blade 5 to cancel the fixing effect of the knife holder 4 and the blade 5 on the knife shaft 6. Then, the position of the knife holder 4 and the blade 5 at the edge on the knife shaft 6 is determined, and the vertical rod 45 at the top is pressed to retract the vertical rod 45 into the telescopic groove 44. The vertical rod 45 drives the rubber piston 46 to slide in the telescopic groove 44. The bottom of the vertical rod 45 pushes the movable block 42 to rotate around the first pin shaft 43, so that the bottom of the movable block 42 squeezes the upper surface of the knife shaft 6 through the toothed protective pad. The squeezing effect of the toothed protective pad limits the movement of the knife holder 4 and the blade 5 relative to the knife shaft 6, so that the knife holder 4 and the blade 5 at the edge are quickly fixed on the knife shaft 6. Then, the motor 813 drives the screw rod 812 to rotate. The screw rod 812 is connected to the transmission belt 814 through the transmission wheel 814. 5 drives another screw rod 812 to rotate, and the two screw rods 812 rotate through the screw holes 811 to drive the slider 81 to slide in the slide groove 7, so that the two sliders 81 drive the cross beam 82 to move until the cross beam 82 moves to the center position between the knife seat 4 and the blade 5, and then the rodless cylinder 83 is started, and the two telescopic cylinders 84 are driven by the rodless cylinder 83 to move to the top of the knife seat 4 and the blade 5, and the distance sensor 86 detects the position of the knife seat 4 or the blade 5 on the knife shaft 6, and then the telescopic cylinder 84 extends to push the pressure block 87 downward, and the pressure block 87 is squeezed on the knife seat 4 and the blade 5 that have been fixed at the edge. When the distance between the knife seat 4 and the blade 5 is increased, the electric telescopic rod 88 is controlled to extend a fixed distance, and the electric telescopic rod 88 drives the push plate 89 to move. 9 pushes an adjacent knife seat 4 and blade 5 to move to the specified position. When the spacing between the knife seat 4 and blade 5 is reduced, the electric telescopic rod 88 is controlled to extend a fixed distance during the downward movement of the pressure block 87. At this time, the knife seat 4 and blade 5 to be moved are between the push plate 89 and the pressure block 87. After the pressure block 87 squeezes the knife seat 4 and blade 5, the electric telescopic rod 88 contracts and moves the push plate 89, so that the push plate 89 moves an adjacent knife seat 4 and blade 5 to the specified position synchronously, and then the rodless cylinder 83 continues to drive the telescopic cylinder 84 to move, and the above operation is repeated. In the subsequent process of the pressure block 87 moving downward to squeeze the knife seat 4 and blade 5, the pressure block 87 squeezes the vertical rod 45 to retract the telescopic groove 44, so that the knife seat 4 and blade 5 are pressed and fixed while adjusting the distance.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
