[0023] In order to make the person skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0024] Figure 1 Figure 1 is a perspective view of a copper-coated steel unwinding and straightening device according to an embodiment of the present application, Figure 2 Figure 1 is a top view of a copper-coated steel unwinding and straightening device according to an embodiment of the present application. Referring to Figure 1 and Figure 2 Figure 1, the present application provides a copper-coated steel unwinding and straightening device, which comprises an unwinding frame 1 and a bottom plate 2, wherein the unwinding frame 1 is located on one side of the bottom plate 2.

[0025] It should be noted that the unwinding frame 1 is fixedly arranged in the side direction of the bottom plate 2, and the unwinding frame 1 is a rotatable structure, which is convenient for carrying and gradually releasing the copper-coated steel coil.

[0026] One end of the bottom plate 2 is fixedly installed with an inlet sleeve 3, and the other end of the bottom plate 2 is fixedly installed with an outlet sleeve 4, wherein the inlet sleeve 3 and the outlet sleeve 4 are coaxial.

[0027] It is easy to understand that the inlet sleeve 3 and the outlet sleeve 4 are both higher than the top surface of the bottom plate 2.

[0028] The top surface of the bottom plate 2 is rotatably installed with a driving wheel 5 and a driven wheel 6, wherein the driving wheel 5 and the driven wheel 6 are opposite to each other, and the driving wheel 5 and the driven wheel 6 are located on the side close to the inlet sleeve 3, and the extension line of the axes of the inlet sleeve 3 and the outlet sleeve 4 passes through between the driving wheel 5 and the driven wheel 6.

[0029] The top surface of the bottom plate 2 is rotatably provided with at least one first straightening wheel 7 and at least one second straightening wheel 8, which are respectively located on both sides of the bottom plate 2 and between the driving wheel 5 and the outlet sleeve 4.

[0030] It is easy to understand that the unwinding frame 1 can rotate for receiving the copper-coated steel coil, the driving wheel 5, the driven wheel 6, the first straightening wheel 7 and the second straightening wheel 8 are all rotatable and are designed to be wear-resistant and flexible in rotation, so as to avoid sliding friction with the copper-coated steel and cause scratch on the surface of the copper-coated steel.

[0031] Taking the copper-coated round steel as an example, the copper-coated round steel coil is placed on the unwinding frame 1, the first end of the copper-coated round steel coil is manually pulled out and sequentially passes through the inlet sleeve 3, the driving wheel 5 and the driven wheel 6, the first straightening wheel 7 and the second straightening wheel 8 and the outlet sleeve 4, the driving wheel 5 is connected with a power device, the periphery of the driving wheel 5, the driven wheel 6, the first straightening wheel 7 and the second straightening wheel 8 is in contact with the outer periphery of the copper-coated round steel, the power device is started, the copper-coated round steel is conveyed to the outlet sleeve 4 through the cooperation between the driving wheel 5 and the driven wheel 6, so as to complete the unwinding and straightening work, which can reduce the labor input, reduce the construction difficulty, improve the work efficiency and avoid personnel injury.

[0032] Further, the periphery of the driving wheel 5, the driven wheel 6, the first straightening wheel 7 and the second straightening wheel 8 is arc-shaped, so as to increase the contact area with the copper-coated round steel and the friction force.

[0033] Specifically, in the operation process, the first end of the copper-coated round steel coil is manually pulled out and straightened for 1-1.2 m, then the straightened copper-coated round steel extends from the inlet sleeve 3 to the outlet sleeve 4, the gap between the driving wheel 5 and the driven wheel 6 allows the copper-coated steel material to pass through, the driving wheel 5 starts to rotate, the driven wheel 6 rotates under the action of the friction force, and the two work together to realize the stable traction and conveying of the copper-coated steel material. The copper-coated round steel is repeatedly stretched through the plurality of first straightening wheels 7 and second straightening wheels 8, the copper-coated round steel coil fixed on the unwinding frame 1 also rotates with the advancement of the copper-coated round steel, and the straightened copper-coated round steel can be output through the cooperation of the inlet sleeve 3 and the outlet sleeve 4, the amount of the copper-coated round steel can be taken according to the required amount of the subsequent construction, which can reduce the straightening work of 3-5 people to 1 person, greatly reduce the cost, effectively guarantee the quality and safety of the copper-coated round steel, and avoid personnel injury or damage to the copper-coated round steel caused by improper operation.

[0034] In some examples, the bottom surface of the bottom plate 2 is fixedly provided with a motor 9, and the output shaft of the motor 9 is connected with the driving wheel 5 through a speed reducer.

[0035] It is easy to understand that the motor 9 is a power device. Specifically, the bottom surface of the bottom plate 2 is designed with a special mounting area to fix and install the motor 9, so as to ensure that the motor 9 can be stably and efficiently installed thereon, while reducing vibration and noise during operation. The motor 9 is selected to be a high-performance and low-energy consumption model, which aims to provide continuous and stable power output.

[0036] Further, the output shaft of the motor 9 is not directly connected with the driving wheel 5, but is connected through a speed reducer, which establishes a conversion bridge between the high-speed rotation of the motor 9 and the low-speed high-torque required by the driving wheel 5. The speed reducer contains multiple sets of precision gears or worm gears inside, which are precisely machined and assembled to ensure the efficiency and stability of power transmission, while effectively reducing the speed of the driving wheel 5 and increasing the torque, making it more suitable for driving the load.

[0037] In some examples, the top surface of the bottom plate 2 is provided with at least two grooves 10, one end of each groove 10 is rotationally connected with one end of a screw rod 11, the other end of the screw rod 11 penetrates the outer end of the corresponding groove 10, and the screw rod 11 is perpendicular to the axis extension line of the inlet sleeve 3;

[0038] The groove 10 is slidably installed with a movable seat 12, the screw rod 11 penetrates the movable seat 12 and threadedly cooperates therewith, and the driven wheel 6 and the second straightening wheel 8 are respectively rotationally installed on the corresponding movable seat 12.

[0039] It is easy to understand that the groove 10 and the screw rod 11 can be connected by bearings, the screw rod 11 penetrates the outer end of the corresponding groove 10 and extends to the outside space of the bottom plate 2, and the staff rotates the screw rod 11. Since the movable seat 12 is slidably connected with the groove 10 and the sliding direction is perpendicular to the axis extension line of the inlet sleeve 3, the movable seat 12 cannot rotate with the screw rod 11, so as to realize the linear movement of the movable seat 12, that is, the driven wheel 6 and the second straightening wheel 8 can be moved towards or away from the driving wheel 5 and the first straightening wheel 7, which can adapt to copper-coated round steel with different diameters to meet different working requirements, thereby greatly improving the adaptability and practicality of the device.

[0040] Further, the periphery of the driving wheel 5, the driven wheel 6, the first straightening wheel 7 and the second straightening wheel 8 is coated with rubber, so as to further increase the friction force with the copper-coated round steel, prevent slipping, and further reduce the probability of scratching the copper-plated surface of the copper-coated round steel.

[0041] In some examples, the bottom surface of the bottom plate 2 is connected to the base 14 through the legs 13, and the base 14 is fixedly installed with the unwinding support 15 away from the end of the bottom plate 2. The rotating shaft of the unwinding frame 1 is rotationally connected to the unwinding support 15.

[0042] It is easy to understand that the bottom plate 2 is lifted by the legs 13, which is more convenient for the staff to operate and provides enough space for the installation of the motor 9 and the speed reducer. In addition, the bottom plate 2 and the unwinding frame 1 are connected through the base 14, which is more convenient for the overall movement of the device.

[0043] Further, the rotating shaft of the unwinding frame 1 is connected to the unwinding support 15 through a bearing. When the unwinding frame 1 rotates relative to the unwinding support 15, the noise is small, and the rotating resistance is also small. When the driving wheel 5 and the driven wheel 6 drive the copper-coated round steel to move, the unwinding frame 1 can be more easily rotated, thereby facilitating the reduction of energy consumption of the motor 9.

[0044] In some examples, the legs 13 and the base 14 can be made of angle steel or channel steel. The above-mentioned materials have low cost and are easy to purchase, and at the same time have enough rigidity and are not easy to deform. In other examples, other suitable materials can also be selected according to actual needs, and the present application does not limit this.

[0045] In some examples, the unwinding frame 1 includes the rotating shaft, and a plurality of fixed supports 101 are fixedly installed on the outer periphery of the rotating shaft. The angle between adjacent two fixed supports 101 is the same, and each fixed support 101 is movably installed with a movable support 102 away from one end of the rotating shaft.

[0046] It is easy to understand that the movable support 102 can move along the corresponding fixed support 101, thereby adjusting the overall diameter of the unwinding frame 1 to adapt to copper-coated round steel of different lengths.

[0047] The number of fixed supports 101 is 3-6, at least 3, so as to prevent the copper-coated steel coil from being placed on it and being unevenly stressed to cause tilting or even falling, and at most 6, so as to prevent the weight of the unwinding frame 1 from being too large to cause the load of the motor 9 to be too large.

[0048] It should be noted that each fixed support 101 is composed of two pipes perpendicular to the rotating shaft and one pipe parallel to the rotating shaft, and the pipes are welded together; each movable support 102 is also welded by three pipes, and the diameter of the pipes of the movable support 102 is slightly smaller than that of the pipes of the fixed support 101, so that the movable support 102 can be inserted into the fixed support 101. In order to prevent the movable support 102 from shaking, the outer periphery of the pipes of the movable support 102 should be fitted to the inner wall of the pipes of the fixed support 101.

[0049] In some examples, the fixed support 101 and the movable support 102 are connected by bolts.

[0050] It is easy to understand that a screw hole is opened on the pipe material perpendicular to the rotating shaft of the fixed support 101, the bolt is screwed with the screw hole, and the inner end of the bolt penetrates into the inside of the fixed support 101 and tightly contacts the outer wall of the pipe material of the movable support 102, so as to adjust the length of the movable support 102 protruding from the fixed support 101, so as to prevent the movable support 102 from falling out of the fixed support 101 during use.

[0051] Further, a shallow blind hole can be opened on the outer wall of the pipe material perpendicular to the rotating shaft of the movable support 102, so that the bolt is inserted therein, and the connection stability between the movable support 102 and the fixed support 101 is improved.

[0052] In some examples, the number of the first straightening wheels 7 is 3-5, the number of the second straightening wheels 8 is 2-4, and the second straightening wheels 8 are located between two adjacent first straightening wheels 7.

[0053] It is easy to understand that the above number range is selected to balance the relationship between the straightening effect and the manufacturing cost. On the one hand, a sufficient number of first straightening wheels 7 and second straightening wheels 8 can ensure that the copper-coated round steel receives uniform and effective straightening force during transmission, thereby improving the straightening precision and efficiency. On the other hand, by reasonably controlling the number of first straightening wheels 7 and second straightening wheels 8, the performance can be ensured while reducing material consumption and manufacturing cost, thereby improving the market competitiveness of the product.

[0054] Especially important is that the second straightening wheel 8 is arranged between two adjacent first straightening wheels 7, which ensures that the copper-coated round steel can continuously and stably receive straightening action during transmission. Through the cooperation of the first straightening wheel 7 and the second straightening wheel 8, multi-stage straightening of the copper-coated round steel is realized, which further improves the straightening precision and efficiency. In addition, this layout also helps to disperse the stress during straightening, reduces material damage and wear, and prolongs the service life of the straightening wheel.

[0055] In actual application, the specific number of the first straightening wheel 7 and the second straightening wheel 8 and their relative positions can be flexibly adjusted according to the diameter of the copper-coated round steel, the bending degree, and the actual needs of the user. For example, for the copper-coated round steel with a large bending degree, the number of first straightening wheels 7 and second straightening wheels 8 can be appropriately increased to enhance the straightening effect. For some copper-coated round steel with a small diameter, the number of straightening wheels can be reduced to avoid material damage caused by excessive straightening.

[0056] It is easy to understand that the skilled in the art can combine, split, recombine, etc. the embodiments of the present application on the basis of the several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.

[0057] The above detailed description of the embodiments of the present application has further detailed the purposes, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above is only a specific implementation of the embodiments of the present application and is not used to limit the protection scope of the embodiments of the present application.
