Description

Technical Field

[0001] This invention relates to the field of amorphous ribbon manufacturing and winding technology, specifically to an amorphous ribbon feeding tension control structure and an amorphous ribbon processing line. Background Technology

[0002] Amorphous ribbon is typically prepared using a rapid solidification process. Molten amorphous alloy material is sprayed onto the surface of a high-speed rotating forming roller, rapidly cooled, and solidified into a thin strip. This strip is then blown out by an air-blowing mechanism, forming a continuous, flowing ribbon. Subsequently, a winding device grips and winds the strip for further processing.

[0003] Tension control is crucial during the winding process of amorphous ribbon. Insufficient tension can cause the ribbon to loosen, wrinkle, or deviate; excessive tension can lead to stretching deformation or even breakage of the ribbon. Summary of the Invention

[0004] In view of the above, it is necessary for the present invention to provide a tension control structure for winding amorphous ribbon to solve the problem of unstable tension control during the winding process.

[0005] The technical solution of the present invention is as follows: A tension control structure for amorphous ribbon feeding includes a blow forming machine, a winding mechanism, and a tension control mechanism. The blow forming machine includes a forming roller with a blowing section located below the front side of the forming roller. The winding mechanism is used to wind up the blown ribbon, and the tension control mechanism is used to adjust the tension of the ribbon during winding.

[0006] The winding mechanism includes a conveyor track and a belt-gripping and winding table slidably mounted on the conveyor track. One end of the conveyor track is adjacent to the belt blowing point of the blow forming machine, and the other end extends along the belt feeding direction.

[0007] The tension control mechanism includes a gantry frame, a lifting beam, and a tension roller. The gantry frame spans both sides of the conveyor track, the lifting beam is vertically mounted on the gantry frame, and the tension roller is rotatably mounted on the lifting beam. The lifting beam lowers the tension roller, causing its surface to press against and pull the strip between the belt take-up table and the blown strip forming machine, thereby adjusting the tension of the strip during take-up.

[0008] Furthermore, the tension roller is provided with a cooling channel for cooling the strip through the tension roller.

[0009] Furthermore, the lifting beam is equipped with a drive motor, which is used to drive the tension roller to rotate and control and adjust the rotation speed.

[0010] Furthermore, the strip gripping and winding table is provided with a winding shaft that can move laterally. The winding shaft is provided with an air flow channel. The air inlet of the air flow channel is opened on the circumferential surface of the winding shaft to form a negative pressure through the air inlet to grip the strip.

[0011] Furthermore, the winding mechanism also includes an auxiliary support mechanism disposed on one side of the conveyor track. The auxiliary support mechanism has a laterally extendable conical top, which extends and abuts against one end of the winding shaft when the gripping winding table moves to align with the auxiliary support mechanism, thereby improving the stability of the winding shaft during winding.

[0012] Furthermore, the winding mechanism comprises two sets, each with two parallel sets of conveyor tracks and two auxiliary support mechanisms. The two gripping and winding tables are respectively installed on the corresponding conveyor tracks, used to alternately wind up the strip material blown out by the blown strip forming machine.

[0013] Furthermore, the lifting beam is equipped with cooling nozzles, which are located on the rear side of the tension roller and are used to air-cool and remove dust from the strip after it passes through the tension roller.

[0014] Furthermore, the gantry frame is provided with a limiting component, which is used to limit the lifting stroke of the lifting beam.

[0015] Furthermore, the top of the gantry frame is equipped with a high-temperature resistant anti-slinging curtain that can be automatically retracted and extended, which is used to shield molten materials that may splash.

[0016] In addition, the present invention also provides an amorphous ribbon processing line having the aforementioned amorphous ribbon feeding tension control structure.

[0017] The beneficial effects of this invention are: 1. By setting up two alternately sliding gripping and winding tables, and in conjunction with a negative pressure adsorption winding shaft, it can automatically grip the flying strip material and achieve continuous winding, resulting in high production efficiency.

[0018] 2. The tension control mechanism adopts a liftable tension roller, combined with screw drive and differential speed control of the drive motor, which can accurately adjust the strip tension and throwing angle to prevent the strip from loosening, wrinkling or stretching deformation. At the same time, the built-in cooling channel cools the strip a second time to ensure the forming quality.

[0019] 3. By setting up cooling air nozzles to air-cool and remove dust from the tensioned strip, the surface cleanliness of the strip is further improved.

[0020] 4. By designing a counterweight balancing structure to balance the eccentric load of the tension roller, and a gear and rack structure to correct the lifting posture of the crossbeam, the strip is prevented from running off-center, and the winding accuracy is improved.

[0026] 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. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1 , Figure 2 As shown, this invention provides an amorphous ribbon feeding tension control structure and an amorphous ribbon processing line. The feeding tension control structure is used for tension regulation and automatic winding in the amorphous ribbon forming process, and includes a blow forming machine 1, a winding mechanism 2, and a tension control mechanism 3. The blow forming machine 1 is arranged on a horizontal base and is equipped with a forming roller 11 that can rotate continuously at a constant speed. Molten amorphous material is sprayed onto the surface of the forming roller 11 and then rapidly cooled and solidified into a solid ribbon. As the forming roller 11 rotates, it is blown by an air blowing mechanism located on the front side of the forming roller 11, which blows air and throws the thin film-like ribbon out, causing the ribbon to be conveyed forward in a flying state.

[0028] The winding mechanism 2 is located at the rear end of the strip conveying direction and is used to grab the strip in a flying state and complete the orderly winding. The tension control mechanism 3 is located between the blown strip forming machine 1 and the winding mechanism 2 and is used to press the strip, regulate the winding tension, and adjust the throwing angle of the strip relative to the forming roller 11 to prevent the strip from leaving the forming roller 11 prematurely due to insufficient cooling, thus ensuring the stability of strip forming and conveying.

[0029] The winding mechanism 2 includes two sets of parallel conveyor tracks 21, two gripping and winding tables 22, and two auxiliary support mechanisms 23. The two sets of conveyor tracks 21 extend along the strip throwing direction of the forming roller 11 and are symmetrically arranged on both sides of the strip width. The two gripping and winding tables 22 are slidably mounted on the corresponding conveyor tracks 21. Each gripping and winding table 22 is equipped with a winding shaft 221 that can slide along the strip width direction. One end of each winding shaft 221 is an air inlet end, and the other end is a winding end. The winding ends of the two gripping and winding tables 22 are arranged facing each other, and the air inlet ends are arranged in opposite directions, so that the two gripping and winding tables 22 can alternately wind the strip to achieve continuous material winding.

[0030] The take-up shaft 221 has an air flow channel inside and an air suction hole on the outer circumference of the take-up end. The air receiving end is used to connect to the air extraction mechanism. The air inside the air flow channel is drawn out by the air extraction mechanism, which can form a negative pressure in the air suction hole, causing the flying strip material to be adsorbed onto the surface of the take-up shaft 221, realizing automatic gripping of the strip material. The rotation of the take-up shaft 221 drives the strip material to be wound around the take-up end.

[0031] In this embodiment, there are two air extraction mechanisms, which are set on both sides of the same end of two sets of parallel conveying tracks 21 and are arranged facing each other on the same straight line.

[0032] Two sets of auxiliary support mechanisms 23 are symmetrically mounted at the end of the conveyor track 21 away from the forming roller 11. Each auxiliary support mechanism 23 has a conical top, which is laterally extended and retracted by a gear and rack mechanism driven by a motor. When the winding shaft 221 reaches the designated position, the conical top extends and abuts against the end of the winding shaft 221, providing support to its free end. During the winding operation, as the diameter and weight of the coil increase, the gripping winding table 22 moves backward along the conveyor track 21, and the free end of the winding shaft 221 continuously cooperates with the conical top for support, effectively preventing shaft deformation and operational vibration, ensuring a smooth and reliable winding operation.

[0033] like Figure 3 , Figure 4 As shown, the tension control mechanism 3 includes a gantry frame 31, a lifting beam 32, a tension roller 33, and a cooling nozzle 34. The gantry frame 31 spans the front end of the two sets of conveying tracks 21 near the forming roller 11. The lifting beam 32 is slidably mounted inside the gantry frame 31. The tension roller 33 is fixed to one side of the lifting beam 32 near the forming roller 11 and moves up and down synchronously with the lifting beam 32 to adjust the degree of compression on the strip.

[0034] The tension roller 33 has an internal coolant circulation channel and an external cooling circulation system, which can further cool down the strip while pressing and adjusting the tension. The tension roller 33 is equipped with a drive motor at its end, which can precisely control its speed, so that the linear speed of the tension roller 33 and the strip conveying speed form a controllable speed difference, accurately adjusting the strip tension and preventing the strip from becoming loose, wrinkled or stretched.

[0035] Cooling nozzle 34 is installed on lifting beam 32 and located behind tension roller 33 along the strip conveying direction. Cooling nozzle 34 is connected to a high-pressure air source and can continuously blow clean airflow onto the strip surface. On the one hand, it performs secondary air cooling on the strip to improve the cooling effect; on the other hand, it blows away dust, molten residue and other impurities on the strip surface to ensure that the strip surface is clean after winding.

[0036] Both sides of the gantry frame 31 are vertically equipped with lifting slide rails 35 on their inner sides. The lifting beam 32 is slidably engaged with the lifting slide rails 35 at both ends via sliders. One end of the lifting beam 32 is equipped with a threaded sleeve. A lead screw 36 matching the threaded sleeve is vertically mounted on the corresponding column of the gantry frame 31. The bottom end of the lead screw 36 is connected to a drive motor 37. The drive motor 37 drives the lead screw 36 to rotate, which drives the threaded sleeve and the lifting beam 32 to slide vertically along the lifting slide rails 35 through threaded transmission, precisely adjusting the height of the tension roller 33 and controlling the tension adjustment of the strip by the tension roller 33.

[0037] Two limiting members 311 are fixedly distributed on the inner side of the other column of the gantry frame 31, which respectively limit the upper and lower limit stroke of the lifting beam 32, so as to prevent the lifting beam 32 from sliding beyond its stroke and causing rigid collision with the equipment, thereby improving the operational stability.

[0038] A counterweight balancing structure is installed at the end of the lifting beam 32 opposite to the screw sleeve. A steering rod 312 is fixed on the gantry frame 31, and a chain is wound around the steering rod 312. The two ends of the chain are connected to the end of the lifting beam 32 and the counterweight block 38, respectively. The gravity of the counterweight block 38 balances the eccentric load of the tension roller 33, so that the lifting beam 32 is subjected to uniform force.

[0039] A balance shaft 321 is provided on the side of the lifting beam 32 opposite to the tension roller 33. Gears are mounted at both ends of the balance shaft 321, and a vertical rack that meshes with the gears is provided on the inner side of the column of the gantry frame 31. During the lifting process of the lifting beam 32, the gears rotate along the rack to correct the beam posture in real time, prevent the lifting beam 32 from tilting or swaying, avoid the strip material from running off-center, and ensure winding accuracy.

[0040] One of the columns of the gantry 31 is hinged with a vertically rotatable stop plate 313. The stop plate 313 is driven to rotate by a matching rotary drive, and its free end can rotate to below the lifting beam 32. The lifting beam 32 is equipped with a speed sensor (not shown in the figure) to monitor the descent speed in real time. By monitoring the motor output power to match the descent speed of the lifting beam 32, when a runaway fault of free fall of the lifting beam 32 is detected, the control system triggers the drive to rotate the stop plate 313 to below the beam, achieving rigid stopping and preventing the lifting beam 32 from falling and damaging the equipment and strip, thereby improving the safety performance of the equipment.

[0041] A gantry frame 31 is equipped with an anti-slip curtain 39 at the top corresponding to the position of the strip conveyor path. The anti-slip curtain 39 is made of high-temperature resistant and fire-resistant flexible material and is wound around a rotatable long shaft. The long shaft is driven by a motor to rotate, realizing the automatic raising and lowering of the anti-slip curtain 39. When the anti-slip curtain 39 is lowered, it can block the uncured and loose molten material thrown out by the forming roller 11, prevent the material from flying away, and improve production safety and site cleanliness.

[0042] The operation process of this invention is as follows: Molten amorphous material is sprayed onto the surface of a continuously rotating forming roller 11, and after rapid heat exchange and cooling, it solidifies to form a solid strip. The formed strip is thrown out as the forming roller 11 rotates. The thrown strip extends to the winding mechanism 2, where the winding shaft 221 precisely grasps the end of the strip through negative pressure adsorption, and continuous winding is achieved by the continuous rotation of the winding shaft 221. Throughout the winding operation, the vertical height of the lifting beam 32 and tension roller 33 can be adjusted in real time by driving the lead screw 36 to rotate through the drive motor 37 according to the forming state and process parameters of the strip. Combined with the controllable speed difference between the tension roller 33 and the strip conveying speed, the clamping force, conveying tension, and throwing angle relative to the forming roller 11 of the strip can be precisely controlled. At the same time, the cooling air nozzle 34 continuously blows clean airflow onto the surface of the tensioned strip to perform secondary air cooling and remove surface impurities, ensuring that the strip is fully cooled and the surface is clean. As winding continues, the diameter and weight of the strip gradually increase. The gripping winding table 22 drives the winding shaft 221 to move backward along the conveying track 21, eventually cooperating with the auxiliary support mechanism 23 to provide auxiliary support for the free end of the winding shaft 221, ensuring the stability of the strip conveying and winding process throughout.

[0043] In summary, the amorphous ribbon feeding tension control structure provided by the present invention, through the cooperation of a blow forming machine 1, a winding mechanism 2 and a tension control mechanism 3, realizes the automatic production and winding of amorphous ribbon; by setting the tension control mechanism 3 to adjust the cooling time and tension during the winding of amorphous ribbon, the forming quality of the ribbon and the stability of equipment operation are effectively improved, and the production defect rate is reduced.
