Description

Technical Field

[0001] This utility model relates to the field of amorphous strip processing equipment, and in particular to an amorphous strip anti-deviation cutting device. Background Technology

[0002] Amorphous ribbon is a new type of energy-saving material made by rapidly cooling molten metal at extremely high speeds. It possesses characteristics such as high saturation magnetic induction, high magnetic permeability, low loss, high resistivity, and high temperature stability. To meet different processing requirements, ensure slitting quality, and improve metering accuracy, amorphous ribbon needs to be cut. Currently available amorphous ribbon cutting devices are prone to ribbon misalignment during the unwinding-slitting-rewinding process. For example, misalignment can occur when placing the amorphous ribbon roll on the unwinding mechanism due to improper installation. Similarly, tension adjustment can be affected by assembly errors in the tensioner, leading to ribbon misalignment. Furthermore, assembly errors during the installation of the guide rollers can cause unevenness and slight tilting, compromising slitting quality. Utility Model Content

[0010] The winding mechanism is located at the left end of the frame. Two winding mechanisms are symmetrically arranged vertically and correspond one-to-one with the floating tensioning mechanism.

[0011] Furthermore, in the aforementioned amorphous ribbon anti-deviation cutting device, the connection structure between the first adjusting roller and the second adjusting roller and the frame is the same. The first adjusting roller is rotatably mounted on the adjusting plate. Four vertical elongated holes are provided around the adjusting plate.

[0012] Furthermore, in the aforementioned amorphous ribbon anti-deviation cutting device, the connection structure between the connecting shaft and the slide is as follows: a straightening plate is vertically arranged on the slide, a mounting plate is connected to the straightening plate by bolts, an optical axis seat is arranged on the mounting plate, the connecting shaft is locked in the optical axis seat, and four first adjusting screws are evenly distributed around the center of the optical axis seat on the mounting plate.

[0018] The advantages of this invention are as follows: When a large amorphous ribbon roll cannot be properly installed in the unwinding mechanism due to its excessive weight, the position of the amorphous ribbon can be adjusted by driving the unwinding mechanism back and forth via a servo slide, preventing the amorphous ribbon from shifting. Furthermore, by setting a correction guide frame, the running amorphous ribbon can be finely adjusted to prevent shifting and thus reduce slitting quality. The floating tensioning mechanism can automatically adjust the tension of the amorphous ribbon, further ensuring slitting quality.

The application scope is defined; a first adjusting bolt is provided on the mounting plate on which the floating roller is installed, a second adjusting bolt is provided on the winding frame connected to the air shaft, and a third adjusting bolt is provided on the cover plate connected to the first guide roller, the second guide roller, and the third guide roller, as well as on the adjusting plate connected to the first adjusting roller and the second adjusting roller. During the assembly process, the corresponding guide roller, adjusting roller, floating roller, or air shaft can be adjusted by turning the corresponding adjusting bolts, so that each guide roller, adjusting roller, floating roller, or air shaft can be kept in a horizontal state, which can effectively reduce the deviation of amorphous ribbon during the conveying of amorphous ribbon.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0031] like Figures 1 to 11 As shown, the amorphous strip anti-deviation cutting device of this utility model includes: a frame 1, on which, from right to left, are arranged an unwinding mechanism 2, a length counting mechanism 3, a deviation correction guide frame 4, a cutting mechanism 5, two floating tensioning mechanisms 6, and two winding mechanisms 7. In this embodiment, the cutting mechanism 5 is prior art and will not be described in detail here. On the left and right sides of the cutting mechanism 5, there are first adjusting rollers 11 that can be adjusted up and down. The first adjusting roller 11 on the right side corresponds vertically to the deviation correction guide frame 4. The conveying surface of the first adjusting roller 11 is not higher than the cutting table 51 in the cutting mechanism 5. The two first adjusting rollers 11 on the left side correspond vertically to the two floating tensioning mechanisms 6. The conveying surface of the first adjusting roller 11 corresponding to the upper floating tensioning mechanism 6 is not lower than the cutting table 51 in the cutting mechanism 5, and the conveying surface of the first adjusting roller 11 corresponding to the lower floating tensioning mechanism 6 is not higher than the cutting table 51 in the cutting mechanism 5. The amorphous strip roll is placed on the unwinding mechanism 2. The amorphous strip is first wound on the length counting mechanism 3 for length counting, then wound on the correction guide frame 4 for fine-tuning and correction, and then wound on the first adjusting roller 11 on the right. The slitting mechanism 5 cuts the amorphous strip. If only a single strip is to be taken, the single strip is wound on any one of the first adjusting rollers 11 on the left, then wound on the floating tensioning mechanism 6 corresponding to the first adjusting roller 11 for tensioning, and finally wound on the winding mechanism 7 corresponding to the floating tensioning mechanism 6 for winding. If two strips need to be taken, the two strips are wound on the two first adjusting rollers 11 on the left respectively, then wound on the two floating rollers 6 respectively, and finally wound on the two winding mechanisms 7 for winding.

[0032] like Figure 1 , Figure 2As shown, the unwinding mechanism 2 is located at the right end of the frame 1. The unwinding mechanism 2 includes: a servo slide 21, which is fixed on the frame 1. An unwinding frame 22 is provided on the slide seat of the servo slide 21. An air shaft 23 is rotatably provided on the unwinding frame 22. A baffle 24 is provided at one end of the unwinding frame 22. A first guide roller 25 is provided on the left side of the unwinding frame 22. A first correction probe 12 is provided on the frame 1 between the unwinding mechanism 2 and the length counting mechanism 3. The first correction probe 12 is located directly above the first guide roller 25. Because the amorphous ribbon roll is heavy, it is easy to fail to install properly when placed on the air shaft 23 in the unwinding mechanism 2 due to excessive weight. Therefore, after the amorphous ribbon roll is placed on the air shaft 23, the unwinding frame 22 is driven to move back and forth by the servo slide 21. Then, the amorphous ribbon is wound downward on the first guide roller 25, and then vertically upward through the first correction probe 12 and wound on the length counting mechanism 3. When the first correction probe 12 detects that the position of the amorphous ribbon has not reached the set position, it indicates that the amorphous ribbon has deviated. The servo slide 21 can then continue to fine-tune the back and forth position of the unwinding frame 22 until the amorphous ribbon no longer deviates.

[0033] like Figure 1 , Figure 3 , Figure 4 As shown, the length counting mechanism 3 is located to the left of the unwinding mechanism 2. The length counting mechanism 3 includes: a length counting bracket 31, which is fixed on the frame 1. A rubber roller 32 is rotatably mounted on the length counting bracket 31 and is connected to the encoder 33. Two second guide rollers 34 are respectively arranged on the left and right sides of the length counting bracket 31. The right side conveying surface of the rightmost second guide roller 34 is aligned vertically with the left side conveying surface of the first guide roller 25. Moreover, the second guide roller 34 is located below the other second guide rollers 34, and the top conveying surface of the second guide roller 34 is horizontally aligned with the bottom conveying surfaces of the other second guide rollers 34. After passing through the first correction probe 12, the amorphous ribbon is vertically wound upwards onto the right and top conveying surfaces of the second guide roller 34 on the right side, away from the length measuring bracket 31. Then, it is horizontally wound to the left onto the second guide roller 34 on the right side, close to the length measuring bracket 31, and then upwards onto the rubber roller 32. From the rubber roller 32, it is wound downwards onto the second guide roller 34 on the left side, close to the length measuring bracket 31, and then horizontally wound onto the second guide roller 34 on the left side, away from the length measuring bracket 31. Finally, it is wound upwards onto the correction guide frame 4. Setting the second guide roller 34 on the right side, away from the length measuring bracket 31, lower than the other second guide rollers 34 ensures that the amorphous ribbon is smoothly wound onto the rubber roller 32. During the winding-unwinding process, the amorphous ribbon drives the rubber roller 32 to rotate through friction. The rotating rubber roller 32 then drives the encoder 33 to rotate, allowing the encoder 33 to perform accurate length measurement.

[0034] like Figure 1 , Figure 5, Figure 6 As shown, the correction guide frame 4 is located between the length counting mechanism 3 and the cutting mechanism 5. The correction guide frame 4 includes: a correction body 41, which is fixed on the frame 1. A reciprocating motor 42 is vertically arranged in the correction body 41. A drive shaft 43 is connected to the reciprocating motor 42. A correction seat 44 is eccentrically connected to the drive shaft 43. Correction rollers 45 are rotatably arranged at the left and right ends of the correction seat 44. Two guide groove plates 46 and a rotating plate 47 are equally divided around the eccentric connection point on the correction body 41. The correction seat 44 is rotatably connected to the rotating plate 47. Two guide wheels 48 are connected to the correction seat 44. The two guide wheels 48 are respectively rolled and locked in the two guide groove plates 46. A second correction probe 49 is arranged on the frame 1 below the correction roller 45 on the left side. The reciprocating motor 42 drives the drive shaft 43 to drive the correction seat 44 to swing. The amorphous strip on the second guide roller 34 first winds upwards onto the right-side correction roller 45, then horizontally passes onto the left-side correction roller 45, then downwards through the second correction probe 49 and winds onto the right-side first adjusting roller 11, and then lays flat to the left on the cutting table 51 of the cutting mechanism 5. When the second correction probe 49 detects that the amorphous strip is shifting forward, the reciprocating motor 42 drives the drive shaft 43 to swing the correction seat 44 backwards, guiding the amorphous strip through the correction roller 45 and resetting the forward-shifted amorphous strip. When the second correction probe 49 detects that the amorphous strip is shifting backwards, the reciprocating motor 42 drives the drive shaft 43 to swing the correction seat 44 forwards, resetting the backward-shifted amorphous strip.

[0035] like Figure 1 , Figure 7 , Figure 8As shown, the floating tensioning mechanism 6 is located between the cutting mechanism 5 and the winding mechanism 7. The two floating tensioning mechanisms 6 are arranged symmetrically, one above the other. Each floating tensioning mechanism 6 includes a floating roller 61, a fixed base 62, and a fine-tuning cylinder 63. The fixed base 62 is fixedly mounted on the frame 1. Parallel guide rods 64 and linear guide rails 65 are provided at the front and rear ends of the fixed base 62. Linear bearings are slidably mounted on the guide rods 64, and linear bearing sliders are slidably mounted on the linear guide rails 65. A slide block 66 is provided between the linear bearing and the linear bearing slider. The fine-tuning cylinder 63 is fixed on the fixed base 62 and connected to the slide block 66. The fine-tuning cylinder 63 is connected to a proportional valve 631. A floating roller 61 is provided at the left end of the fixed base 62. A rangefinder 68 capable of measuring the distance of the slide 66 is provided. A straightening plate 661 is vertically mounted on the slide 66. A mounting plate 662 is bolted to the straightening plate 661. An optical axis seat 663 is mounted on the mounting plate 662. A connecting shaft 664 is clamped in the optical axis seat 663. The floating roller 61 is rotatably mounted on the connecting shaft 664. Four first adjusting screws are evenly distributed around the center of the optical axis seat 663 on the mounting plate 662. A first adjusting bolt 67 is threaded onto the four first adjusting screws. The first adjusting bolt 67 abuts against the straightening plate 661. Due to assembly errors when the connecting shaft 664 is inserted into the optical axis seat 663, the connecting shaft 664 and the floating roller 61 may experience problems. If the moving roller 61 tilts slightly and cannot maintain a horizontal position, slightly tighten the corresponding first adjusting bolt 67 to adjust the angle of the mounting plate 662 until the connecting shaft 664 and the floating shaft 61 are horizontal. Then, lock the mounting plate 662 onto the straightening plate 661 with bolts. Two third guide rollers 13 and a second adjusting roller 14 are arranged on the left side of the floating tensioning mechanism 6. The two third guide rollers 13 are horizontally aligned. The amorphous strip material cut by the cutting mechanism 5 is wound around the first adjusting roller 11 and then wound to the left onto any one of the third guide rollers 13. Then, it is wound from the third guide roller 13 to the right and upward onto the floating roller 61, and then from the floating roller 61 to the left onto the second adjusting roller 14 before being wound back up. In the winding mechanism 7, during the conveying of amorphous strip, the opening of the proportional valve 631 controls the movement stroke of the piston rod in the fine-tuning cylinder 63, thereby controlling the left and right positions of the slide 66. When the tension of the amorphous strip is insufficient, the proportional valve 631 drives the fine-tuning cylinder 63 to control the slide 66 and the floating roller 61 to move to the right, increasing the tension of the amorphous strip. When the tension of the amorphous strip is too high, the proportional valve 631 drives the fine-tuning cylinder 63 to control the slide 66 and the floating roller 61 to move to the left, reducing the tension of the amorphous strip. During the adjustment of the tension of the amorphous strip, the distance of the slide 66 is monitored by the rangefinder 68 to control the movement stroke of the slide 66, preventing excessive movement that would cause the amorphous strip to be too tight or too loose.The two horizontally aligned third guide rollers 13 can be selected according to actual production requirements. When the tension required for the amorphous strip is small, the third guide roller 13 on the right side closer to the floating roller 61 can be selected. The tension of the amorphous strip is reduced by decreasing the distance between the third guide roller 13 and the floating roller 61. When the tension required for the amorphous strip is large, the third guide roller 13 on the left side further away from the floating roller 61 can be selected. The tension of the amorphous strip is increased by increasing the distance between the third guide roller 13 and the floating roller 61.

[0036] like Figure 1 , Figure 7 As shown, the connection structure between the first adjusting roller 11 and the second adjusting roller 14 and the frame 1 is the same. Taking the connection structure between the first adjusting roller 11 and the frame 1 as an example, the first adjusting roller 11 is rotatably mounted on the adjusting plate 111. Four vertical elongated holes 1111 are provided around the adjusting plate 111. Connecting bolts 1112 are threaded through the four elongated holes 1111. The connecting bolts 1112 are threaded onto the frame 1. Loosening the connecting bolts 1112 allows the adjusting plate 111 to move up and down, thereby achieving fine adjustment of the up and down position of the first adjusting roller 11. By finely adjusting the up and down position of the first adjusting roller 11, the amorphous ribbon wound from the first adjusting roller 11 can be better wound onto the winding mechanism 7.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 7 The first guide roller 25, the second guide roller 34, and the third guide roller 13 are all fixed to the frame 1 by a cover plate. Each cover plate has four third adjusting screws evenly distributed around its circumference. The adjusting plate 111, which is connected to the first adjusting roller 11 and the second adjusting roller 14, also has four third adjusting screws evenly distributed around its circumference. Each third adjusting screw is threaded with a third adjusting bolt 1113, which abuts against the frame 1. Thus, when the guide rollers or adjusting rollers cannot maintain a horizontal state due to assembly errors, the angle of the cover plate or adjusting plate 111 is adjusted by turning the corresponding third adjusting bolt 1113 until the corresponding guide rollers or adjusting rollers are kept horizontal.

[0038] like Figure 1 , Figure 9 , Figure 10 , Figure 11As shown, the winding mechanism 7 is located at the left end of the frame 1. Two winding mechanisms 7 are symmetrically arranged vertically and correspond one-to-one with two floating tensioning mechanisms 6. An adjusting frame 15 connected to the frame 1 is located at the left end of the frame 1. The two winding mechanisms 7 are respectively located in the upper and lower chambers of the adjusting frame 15. Each winding mechanism 7 includes: a movable plate 71 slidably disposed in the adjusting frame 15; a push-pull cylinder 72 disposed on the adjusting frame 15 and connected to the movable plate 71; a winding frame 73 disposed on the movable plate 71; a rotating shaft 731 rotatably disposed on the winding frame 73; an air shaft 23 disposed on the rotating shaft 731; and a servo motor 74 disposed on the winding frame 73. The servo motor 74 is connected to the rotating shaft 731 via a belt drive. When winding is required, the winding mechanism 7... An I-shaped disc 75 is mounted on the air shaft 23. The moving plate 71 is moved to the right by the push-pull cylinder 72. The amorphous strip wound on the second adjusting roller 14 is then wound downward and to the left onto the I-shaped disc 75. During winding, the second adjusting roller 14 needs to be adjusted downward so that the bottom conveying surface of the second adjusting roller 14 is lower than the top position of the air shaft 23. This ensures that the amorphous strip on the second adjusting roller 14 can maintain good tension when wound onto the I-shaped disc 75. The servo motor 74 drives the rotating shaft 731 and the air shaft 23 on the rotating shaft 731 to rotate via belt drive, and the winding operation can begin. When the winding is finished, the servo motor 74 stops rotating, the amorphous strip is cut off, and then the moving plate 71 is moved to the left by the push-pull cylinder 72, and the fully loaded I-shaped disc 75 is removed. In this embodiment, dampers 76 are provided at both ends of the moving plate 71, and limiting plates 151 that can cooperate with dampers 76 are provided on the left and right side walls of the upper and lower chambers of the adjusting frame 15. When the push-pull cylinder 72 drives the moving plate 71 to move left and right, the dampers 76 on the moving plate 71 can contact the limiting plates 151 to play a buffering role. A set screw plate 731 is provided at both the front and rear ends of the left and right side walls of the winding frame 73. Two second adjusting set screws are provided on the set screw plate 731. A second adjusting bolt 732 is threadedly connected to the second adjusting set screw. The second adjusting bolt 732 abuts against the moving plate 71. When the rotating shaft 731 and the air shaft 23 on the rotating shaft 731 cannot maintain a horizontal state due to assembly errors, the angle of the winding frame 73 is adjusted by turning the corresponding second adjusting bolt 732 until the air shaft 23 on the rotating shaft 731 is kept horizontal. After the air shaft 23 is kept horizontal, the winding frame 73 is fixed on the moving plate 71.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
