Description

Technical Field

[0001] This utility model relates to the technical field of steel strip production equipment, specifically a winding mechanism for steel strip processing. Background Technology

[0002] In the complete processing flow of steel strip, it is necessary to go through many preceding processes such as hot rolling, cold rolling, surface grinding, deburring, cleaning and drying. As the core equipment in the later stage of processing, the winding mechanism undertakes the key task of neatly winding the continuously processed long strip of steel strip into a coil. Its winding quality directly determines the safety of subsequent storage and transportation of steel strip and the accuracy of secondary processing. It is an important link connecting the preceding process and downstream application.

[0003] However, traditional steel strip winding does not effectively hold both ends together, leading to easy deviation during winding. Alternatively, simple metal baffles may be used for coarse blocking, failing to provide stable support at both ends. During winding, fluctuations in the steel strip conveyor speed and slight vibrations of the winding shaft can cause the steel strip to deviate axially. This deviation also results in uneven tension distribution, with the deviated side winding too tightly and the non-deviated side too loose, creating an irregular coil shape with one side bulging and the other collapsing. Therefore, we provide a winding mechanism for steel strip processing. Utility Model Content

[0004] The purpose of this invention is to provide a winding mechanism for steel strip processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a winding mechanism for steel strip processing, comprising a winding frame, wherein bases are provided at the four corners of the bottom of the winding frame, and a winding connection assembly is provided on the winding frame, the winding connection assembly being used to wind up the steel strip.

[0006] Preferably, the winding connection assembly includes a motor mounting plate, which is disposed on the top of the winding machine frame, and a winding motor is disposed on the top of the motor mounting plate.

[0007] Preferably, a motor shaft connector is provided at the right end of the output shaft of the winding motor, a winding shaft is provided at the right end of the motor shaft connector, and a winding plate is provided on the surface of the winding shaft.

[0008] Preferably, the surface of the take-up shaft is provided with two bakelite baffles, both of which are cylindrical in shape, and the surface of the take-up shaft is provided with positioning guide blocks.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model features two cylindrical bakelite baffles on the surface of the winding shaft. On one hand, these baffles firmly hold the two ends of the steel strip, forming a rigid and fitting limiting structure. Compared to traditional designs with no limit or coarse obstruction by metal baffles, this completely prevents axial displacement of the steel strip caused by fluctuations in conveying speed and slight vibrations of the winding shaft during winding. This reduces burrs and interlayer wrinkles caused by displacement, thus lowering the scrap rate of the steel strip. On the other hand, bakelite is tough, smooth, and has no sharp metal edges. It will not scratch the edges of the steel strip when in contact with them, effectively protecting the oxide layer and appearance integrity of the steel strip. This is especially suitable for steel strip processing scenarios with high surface quality requirements, such as appliance panels and automotive interior parts, eliminating the need for subsequent polishing and repair processes required by traditional metal baffles.

[0011] 2. The motor shaft connector of this utility model can accurately ensure the coaxiality of the output shaft of the winding motor and the winding shaft, reduce the vibration caused by assembly deviation, and avoid the sudden change in local tension caused by the misalignment of the shafts in traditional transmission. At the same time, the smooth outer surface of the cylindrical winding plate provides a uniform winding reference surface for the steel strip, so that the steel strip can be tightly and evenly arranged along the circumference of the winding plate during the winding process, which completely solves the problem of irregular rolls with one side bulging and the other side collapsing caused by the excessive tightness on the offset side and the excessive looseness on the non-offset side in traditional winding.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3A winding mechanism for steel strip processing includes a winding frame 1. Both the winding frame 1 and the base 100 are made of Q235 steel. The winding frame 1 serves as the basic load-bearing frame of the entire winding mechanism, bearing the entire weight of the winding connection assembly 2. It also provides a stable installation reference for each component, ensuring that each structure maintains a fixed relative position during the winding process and avoiding the impact of frame swaying on winding accuracy. The base 100 is provided at each of the four corners of the bottom of the winding frame 1. The winding frame 1 is fixedly connected to the base 100 by welding. The welding connection can form an integrated structure between the winding frame 1 and the base 100. Compared with bolt connection, it reduces the risk of loosening caused by long-term vibration and further improves the overall rigidity of the winding frame 1. Mounting holes are provided at each of the four corners of the top of the base 100. With the help of external bolts and mounting holes, the base 100 can be fixed in a suitable position, ensuring the stability of the entire device during use. The vibration of the winding motor 22 during operation will not cause the mechanism to shift, reducing the steel strip winding deviation caused by displacement from the root.

[0018] A winding connection assembly 2 is provided on the winding frame 1. The winding connection assembly 2 is used to wind up the steel strip. The winding connection assembly 2 includes a motor mounting plate 21, which is located on the top of the winding frame 1. The top of the motor mounting plate 21 has several fixing holes, so that the motor mounting plate 21 is fixedly connected to the winding frame 1 by bolts. Compared with welding, the connection method of bolts and fixing holes facilitates the disassembly and adjustment of the motor mounting plate 21. If the motor needs to be repaired or replaced, there is no need to cut or weld; only the bolts need to be removed, reducing the later maintenance cost. The motor mounting plate 21 serves as the supporting base for the winding motor 22, responsible for supporting the motor. The motor is stably fixed on the top of the winding machine frame 1, while ensuring the coaxiality of the motor output shaft and the winding shaft 24. The top of the motor mounting plate 21 is equipped with a winding motor 22, which is fixedly connected to the motor mounting plate 21 by welding. The winding motor 22 provides the winding power source, and drives the motor shaft connector 23 and the winding shaft 24 to rotate through the output shaft, ultimately realizing the winding of the steel strip. The winding motor 22 is made of a horizontal three-phase motor with a power of 7500w. Compared with a single-phase motor, the three-phase motor has a more stable power output, which can ensure that the winding shaft 24 rotates at a constant speed and avoid uneven winding of the steel strip due to sudden changes in speed.

[0019] A motor shaft connector 23 is provided at the right end of the output shaft of the take-up motor 22. The motor shaft connector 23 acts as a power transmission bridge, connecting the output shaft of the take-up motor 22 to the take-up shaft 24, accurately transmitting the motor torque to the take-up shaft 24 while compensating for minor installation errors. The motor shaft connector 23 is fixedly connected to the output shaft of the take-up motor 22 via a flange. The take-up shaft 24 is located at the right end of the motor shaft connector 23. The take-up shaft 24 serves as the core support shaft for the take-up actuator, driving the take-up plate 25 to rotate and achieve steel strip winding. It also serves as a guide for the take-up plate 25, bakelite baffle 26, and positioning guide block 2. 7. A mounting carrier is provided to ensure synchronous rotation of all components. The surface roughness of the precision-machined take-up shaft 24 is ≤Ra1.6, which ensures the fit of components such as the take-up plate 25 and bakelite baffle 26, preventing relative sliding between components and the shaft due to gaps, ensuring synchronous rotation of all components, and improving the winding regularity. The motor shaft connector 23 is fixedly connected to the take-up shaft 24 via a flange. The surface of the take-up shaft 24 is provided with a take-up plate 25. The inner wall of the take-up plate 25 is fixedly connected to the surface of the take-up shaft 24 by welding. The take-up plate 25 is made of 304 austenitic stainless steel. The take-up plate 25 serves as a steel... The direct carrier with winding provides a flat and smooth winding reference surface, ensuring that the steel strip is neatly arranged along the circumferential direction and avoiding interlayer wrinkles. Two bakelite baffles 26 are provided on the surface of the take-up shaft 24. These baffles, made of bakelite, act as limiting components at both ends of the steel strip, preventing axial displacement during winding and protecting the edges from scratches. The left-side baffle 26 is positioned between the motor shaft connector 23 and the take-up plate 25, while the right-side baffle 26 is positioned to the right of the take-up plate 25. The bakelite baffles 26 are attached to the take-up shaft by welding or bolting. 24 is fixedly connected, and the two bakelite baffles 26 form a left and right clamping limiting structure, which completely blocks the axial offset path of the steel strip. If bolts are used for fixing, the baffle spacing can be adjusted according to the width of the steel strip, which is suitable for processing steel strips of various specifications. The flexibility is much higher than that of traditional fixed spacing baffles. The winding plate 25 and the bakelite baffle 26 are both cylindrical. The surface of the winding shaft 24 is provided with a positioning guide block 27. The inner wall of the positioning guide block 27 is fixedly connected to the surface of the winding shaft 24 by a threaded connection. The motor shaft connector 23, the winding shaft 24, the motor mounting plate 21 and the positioning guide block 27 are all made of 45 steel.

[0020] When in use, align the steel strip head precisely between the two bakelite baffles 26, manually rotate the positioning guide block 27, the positioning guide block 27 drives the winding shaft 24 to rotate, so that the steel strip head is wound around the surface of the winding plate 25 1-2 times, and the cylindrical smooth surface of the winding plate 25 is used to achieve initial adhesion.

[0021] Connect the three-phase power supply to the take-up motor 22, start the motor and adjust the speed according to the thickness of the steel strip. The speed of thin steel strip is controlled at 10-15 r / min, and the speed of thick steel strip is controlled at 5-10 r / min. Relying on the stable power output of the three-phase motor, the take-up shaft 24 is ensured to rotate at a constant speed. The torque of the take-up motor 22 is accurately transmitted to the take-up shaft 24 through the motor shaft connector 23. The take-up shaft 24 drives the take-up plate 25, bakelite baffle 26 and positioning guide block 27 to rotate synchronously, thereby driving the steel strip to be wound. The bakelite baffle 26 limits the two ends of the steel strip.
