Description

Technical Field

[0001] This utility model belongs to the field of slitting machine technology, specifically an automatic knife setting device for a vapor phase rust-preventive paper slitting machine. Background Technology

[0002] Vapor phase corrosion inhibitor paper (VCIPaper) is a core material for rust-proof packaging of metal products and is widely used in automotive parts, machinery hardware, electronic components and other fields. Its slitting quality directly determines the sealing performance and rust-proofing time of the subsequent packaging. The edges of the paper after slitting must be free of burrs and the slitting width deviation must be ≤±0.5mm (otherwise it is easy to cause gaps in the packaging overlap, which will cause leakage of VCI rust-proofing factors). It also needs to be compatible with the slitting requirements of special structure vapor phase corrosion inhibitor paper with different thicknesses of 10-75μm and some composite aluminum foil / woven fabric.

[0003] Early vapor phase rust-preventive paper slitting machines commonly used a "manual calibration + feeler gauge inspection" method for blade alignment. The operation process was as follows: after stopping the machine, the blade holder fixing bolts were loosened manually, the alignment of the blade with the baseline was observed visually, the lateral position of the blade was manually adjusted, and then the shearing gap between the upper and lower blades was measured with a feeler gauge (which needed to be controlled within 0.03-0.1mm). This method had significant drawbacks: low efficiency: a single blade alignment adjustment takes 20-40 minutes, and downtime accounts for more than 30% when switching between multiple specifications, making it unsuitable for high-speed production lines; unstable accuracy: relying on the operator's experience, the slitting width error often reaches ±1-2mm, easily leading to problems such as "slitting deviation" and "edge burrs," resulting in sealing failure during rust-preventive paper packaging; safety risks: manual adjustment near the high-speed rotating rollers poses a risk of mechanical pinching injury.

[0004] Therefore, this utility model provides an automatic blade setting device for a vapor phase rust-preventive paper slitting machine. Utility Model Content

[0005] To overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, an automatic knife setting device for a vapor phase rust-preventive paper slitting machine is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An automatic blade setting device for a vapor phase rust-preventive paper slitting machine, comprising a base plate; brackets are fixedly installed on both sides of the top of the base plate; a rotating mechanism is provided on the inner wall of the brackets; a sliding mechanism is provided on the surface of the rotating mechanism; a cutting component is provided on the surface of the rotating roller; a pushing mechanism is provided on both sides of the inner wall of the brackets; a driving mechanism is provided at the bottom of the inner wall of the brackets; a calibration component is provided on the inner wall of the pushing mechanism; the rotating mechanism includes a rotating shaft, a first servo motor, and gears; two sets of rotating shafts are provided, rotatably installed on the top and bottom of the inner wall of the brackets; one side of the bracket is fixedly installed with the first servo motor; the output end of the first servo motor is fixedly installed with one set of rotating shafts; the end of the rotating shaft away from the first servo motor is fixedly installed with a gear; the two sets of gears mesh with each other; the coordinated use of the rotating shaft, the first servo motor, and the gears enables the sliding mechanism to rotate, allowing the sliding mechanism to drive the cutting component to rotate, thereby achieving the slitting effect and ensuring the normal operation of the device.

[0007] Preferably, the sliding mechanism includes a guide plate, a rotating roller, and a calibration rod. The guide plate is fixedly installed on one side of the rotating shaft surface, and the rotating roller is slidably installed on the surfaces of the rotating shaft and the guide plate. Four sets of calibration rods are provided, and the four sets of calibration rods are fixedly installed in a ring at both ends of the rotating roller. In this scheme, the guide plate can drive the rotating roller to rotate synchronously when the rotating shaft rotates, without affecting the normal sliding of the rotating roller. The rotating roller can provide stable support for the cutting assembly, and the calibration rod can provide assistance for automatic tool setting.

[0008] Preferably, the cutting assembly includes bolts and cutters. The cutters are arranged in four sets, and the four sets of cutters are movably mounted in a ring on the surface of the rotating roller near the calibration rod. The cutters are threadedly installed on the rotating roller by bolts. In this scheme, the cooperation between the cutters and bolts can achieve the slitting effect. At the same time, multiple sets of cutters are individually detachable, so that they can be replaced quickly and promptly when damaged.

[0009] Preferably, the pushing mechanism includes a guide rod, a U-shaped plate, and a pushing ring. The guide rod is movably inserted into both sides of the inner wall of the bracket. The end of the guide rod away from the bracket is fixedly installed with the U-shaped plate. The top and bottom of the U-shaped plate are fixedly installed with the pushing ring. The inner wall of the pushing ring is movably connected to the rotating shaft. In this scheme, the guide rod can provide guidance for the U-shaped plate, enabling it to extend and retract stably. The cooperation between the U-shaped plate and the pushing ring can achieve clamping through the drive mechanism, thereby pushing the two sets of rotating rollers to keep them centered, thus achieving horizontal alignment.

[0010] Preferably, the driving mechanism includes forward and reverse screws, a second servo motor, and a connecting plate. The forward and reverse screws are rotatably mounted on the bottom of the inner wall of the bracket. One side of the bracket is fixedly mounted to the second servo motor, and the output end of the second servo motor is fixedly mounted to the forward and reverse screws. Two sets of connecting plates are provided, and the two sets of connecting plates are threaded onto the two ends of the surface of the forward and reverse screws. The top of the connecting plate is fixedly mounted to the push ring. In this scheme, the coordinated use of the forward and reverse screws, the second servo motor, and the connecting plate can achieve the effect of automatically driving the movement of the pushing mechanism, so that no manual intervention is required during calibration, and the entire process is automated, greatly saving manpower.

[0011] Preferably, the calibration assembly includes a fixed cylinder and a Y-shaped alignment hole. The fixed cylinder is fixedly installed on the top and bottom of the inner wall of the U-shaped plate. The fixed cylinder has a Y-shaped alignment hole on the side near the rotating roller. The calibration rod is movably inserted into the fixed cylinder through the Y-shaped alignment hole. In this scheme, the cooperation between the fixed cylinder and the Y-shaped alignment hole allows the calibration rod to be inserted into the Y-shaped alignment hole when the U-shaped plate clamps the rotating roller. Since the calibration rod is flush with the cutter, the two sets of uneven cutters will be accurately aligned after the calibration rod is inserted into the fixed cylinder.

The automatic blade setting device of the vapor phase rust-preventive paper slitting machine of this utility model, through the arrangement of a rotating shaft, a first servo motor, gears, a guide plate, a rotating roller, and a calibration rod, enables the rotating shaft, the first servo motor, and gears to work together to drive the sliding mechanism to rotate, thereby enabling the sliding mechanism to drive the cutting component to rotate, thus achieving the slitting effect and ensuring the normal operation of the device. The guide plate enables the rotating shaft to rotate synchronously with the rotating roller without affecting the normal sliding of the rotating roller. The rotating roller provides stable support for the cutting component, and the calibration rod provides assistance for automatic blade setting.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, an automatic blade setting device for a vapor phase rust-preventive paper slitting machine includes a base plate 1; brackets 2 are fixedly installed on both sides of the top of the base plate 1, a rotating mechanism 3 is provided on the inner wall of the brackets 2, and a sliding mechanism 4 is provided on the surface of the rotating mechanism 3; a cutting component 5 is provided on the surface of the rotating roller 42, and a pushing mechanism 6 is provided on both sides of the inner wall of the brackets 2; a driving mechanism 7 is provided at the bottom of the inner wall of the brackets 2, and a calibration component 8 is provided on the inner wall of the pushing mechanism 6; the rotating mechanism 3 includes a rotating shaft 31, a first servo motor 32, and a gear 33, and two sets of rotating shafts 31 are provided, with the two sets of rotating shafts 31 rotatably installed on the top of the inner wall of the brackets 2. The top and bottom of the bracket 2 are fixedly installed on one side of the first servo motor 32. The output end of the first servo motor 32 is fixedly installed on one of the sets of rotating shafts 31. The end of the rotating shaft 31 away from the first servo motor 32 is fixedly installed on a gear 33. The two sets of gears 33 mesh with each other. The sliding mechanism 4 includes a guide plate 41, a rotating roller 42 and a calibration rod 43. The guide plate 41 is fixedly installed on one side of the surface of the rotating shaft 31. The rotating roller 42 is slidably installed on the surfaces of the rotating shaft 31 and the guide plate 41. Four sets of calibration rods 43 are provided. The four sets of calibration rods 43 are fixedly installed in a ring at both ends of the rotating roller 42. The cutting assembly 5 includes a bolt 52 and a cutter 51. The cutter 51 is provided in four sets, which are movably mounted in a ring on the surface of the rotating roller 42 near the calibration rod 43. The cutter 51 is threadedly installed on the rotating roller 42 by bolts 52. The pushing mechanism 6 includes a guide rod 61, a U-shaped plate 62 and a pushing ring 63. The guide rod 61 is movably inserted into both sides of the inner wall of the bracket 2. The end of the guide rod 61 away from the bracket 2 is fixedly installed with the U-shaped plate 62. The top and bottom of the U-shaped plate 62 are fixedly installed with the pushing ring 63. The inner wall of the pushing ring 63 is movably connected to the rotating shaft 31. The driving mechanism 7 includes a forward and reverse screw 71, a second servo motor 72 and a connecting plate 73. The forward and reverse screw 71 rotates and is mounted on the rotating shaft 31. The bottom of the inner wall of the bracket 2 is fixedly installed on one side of the bracket 2 with the second servo motor 72. The output end of the second servo motor 72 is fixedly installed with the forward and reverse screws 71. Two sets of connecting plates 73 are provided. The two sets of connecting plates 73 are threadedly installed on both ends of the surface of the forward and reverse screws 71. The top of the connecting plate 73 is fixedly installed with the push ring 63. The calibration component 8 includes a fixed cylinder 81 and a Y-shaped alignment hole 82. The fixed cylinder 81 is fixedly installed on the top and bottom of the inner wall of the U-shaped plate 62. The fixed cylinder 81 has a Y-shaped alignment hole 82 on the side near the rotating roller 42. The calibration rod 43 is movably inserted into the fixed cylinder 81 through the opening of the Y-shaped alignment hole 82.

[0026] like Figures 1 to 5As shown, the combined use of the rotating shaft 31, the first servo motor 32, and the gear 33 enables the sliding mechanism 4 to rotate, thus allowing the cutting assembly 5 to rotate and achieve a slitting effect, ensuring the normal operation of the device. The guide plate 41 allows the rotating shaft 31 to rotate synchronously with the rotating roller 42 without affecting the normal sliding of the rotating roller 42. The rotating roller 42 provides stable support for the cutting assembly 5. The calibration rod 43 provides assistance for automatic blade setting. The combination of the cutter 51 and the bolt 52 achieves the slitting effect. Furthermore, multiple sets of cutters 51 are individually detachable, allowing for quick and timely replacement in case of damage. The guide rod 61 provides guidance for the U-shaped plate 62, ensuring its stable operation. The telescopic U-shaped plate 62 and the push ring 63 work together to achieve clamping through the drive mechanism 7, thereby pushing the two sets of rotating rollers 42 to keep them centered, thus achieving horizontal alignment. The cooperation of the forward and reverse screws 71, the second servo motor 72 and the connecting plate 73 can achieve the effect of automatically driving the push mechanism 6 to move, so that no manual intervention is required during alignment, and the whole process is automated, which greatly saves manpower. The cooperation of the fixed cylinder 81 and the Y-shaped alignment hole 82 can allow the alignment rod 43 to be inserted into the Y-shaped alignment hole 82 when the U-shaped plate 62 clamps the rotating rollers 42. Since the alignment rod 43 is flush with the cutter 51, the two sets of uneven cutters 51 will be accurately aligned after the alignment rod 43 is inserted into the fixed cylinder 81.

[0027] Working principle: During operation, the base plate 1 is first placed on a flat surface. Then, the user places the vapor phase corrosion inhibitor paper at the intersection of the two sets of rotating rollers 42. The first servo motor 32 is then activated to drive the rotating shaft 31 and gear 33 to rotate. The rotation of gear 33 drives the other set of rotating shafts 31 to rotate synchronously, allowing the two sets of rotating shafts 31 to rotate in opposite directions. The rotation of the rotating shafts 31 drives the rotating rollers 42 to rotate synchronously via the guide plate 41. The rotating rollers 42 convey the vapor phase corrosion inhibitor paper. As the rotating rollers 42 continue to rotate, the two sets of cutters 51 overlap, thus cutting the vapor phase corrosion inhibitor paper. Over time... When a deviation occurs between the two sets of cutters 51, the user first starts the second servo motor 72 to drive the forward and reverse screws 71 to rotate. The rotation of the forward and reverse screws 71 will drive the two sets of connecting plates 73 to move towards the center. The movement of the connecting plates 73 will drive the push rings 63 and the U-shaped plate 62 to move synchronously. As the two sets of push rings 63 move continuously, they will clamp the rotating roller 42, thereby pushing the guide plate 41 to keep it centered. At the same time, the fixed cylinder 81 will move synchronously with the U-shaped plate 62, so that the deviation correction rod 43 can be inserted into the Y-shaped alignment hole 82, and the two sets of correction rods 43 can be recalibrated through the Y-shaped alignment hole 82.
