[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Reference Figure 1 and Figure 2 , an embodiment of the utility model is provided: an unwinding machine, including a base 1, a support frame 2 is provided on one side of the base 1, a limiting groove 24 is provided inside the support frame 2, a sleeve 7 is slidably connected inside the support frame 2, a motor 15 is fixedly connected to one side of the support frame 2, a threaded rod 6 is fixedly connected to the output end of the motor 15, the outer wall of the threaded rod 6 is threadedly connected to the inside of the sleeve 7, the outer wall of the sleeve 7 is rotatably connected to the support rod 8, one end of the support rod 8 is rotatably connected to a clamping plate 9, one side of the clamping plate 9 is fixedly connected to a limiting block 10, the outer wall of the limiting block 10 is slidably connected to the inside of the limiting groove 24, a limiting groove 13 is provided inside the base 1, a limiting component is provided on one side of the support frame 2, the limiting component includes a limiting wheel 14, one side of the limiting wheel 14 is rotatably connected to the inside of the support frame 2, and the outer wall of the limiting wheel 14 is slidably connected to the inside of the limiting groove 13;

[0039] Specifically, the output end of the motor 15 is closely connected to the threaded rod 6, and the motor 15 drives the threaded rod 6 to start rotating. As the threaded rod 6 rotates, the sleeve 7 that closely matches it begins to move slowly along the direction of the support frame 2. This movement is not random, but the result of precise calculation and control. In the movement of the sleeve 7, the support rod 8 plays a vital role. It is like a tough backbone, supporting the expansion of the clamping plate 9. The expansion of the clamping plate 9 is not a simple linear motion, but is achieved by the sliding limit of the limit block 10 in the limit groove 24. This design not only ensures the stability of the expansion of the clamping plate 9, but also ensures that it can accurately fix the coil when it is expanded. When the clamping plate 9 is expanded, the coil is firmly fixed. This fixing method is not only firm and reliable, but also can adapt to coils of different sizes and shapes. Through the precise control of the motor 15, the entire clamping and fixing process can be completed in a very short time, greatly improving production efficiency.

[0040] Reference Figure 3 and Figure 4A motor 2 11 is fixedly connected to one side of the base 1, a worm 12 is fixedly connected to the output end of the motor 2 11, a worm gear 13 is fixedly connected to one side of the support frame 2, the worm gear 13 is meshed with the outer wall of the worm 12, a pillar 15 is fixedly connected to the top of the base 1, a fixed seat 16 is fixedly connected to the top of the pillar 15, a guide wheel 17 is rotatably connected inside the fixed seat 16, the guide wheel 17 is symmetrically arranged and rotatably connected inside the fixed seat 16, a telescopic rod 18 is fixedly connected inside the fixed seat 16, one end of the telescopic rod 18 is fixedly connected to a clamping block 19, a spring 20 is sleeved on the outer wall of the telescopic rod 18, one end of the spring 20 is fixedly connected to the inside of the fixed seat 16, and the other end of the spring 20 is fixedly connected to the top of the clamping block 19, and the telescopic rod 18 and the spring 20 are arranged in a linear array and provided with a plurality of groups;

[0041] Specifically, in modern industrial production, steel plates, as an important raw material, are widely used in various fields. In order to ensure the stability and safety of steel plates during the production process, we need an efficient fixing and rotating device. This article will introduce in detail the working principle and advantages of a steel plate fixing and rotating device.

[0042] First, when the steel plate passes through the interior of the fixed seat 16, the clamping block 19 will fix the steel plate under the push of the telescopic rod 18. At the same time, the tension of the spring 20 will also play a supporting role to ensure that the steel plate will not move inside the fixed seat 16. This double fixing method not only improves the stability of the steel plate, but also effectively prevents the displacement and shaking of the steel plate during processing. In addition, the setting of the guide wheel 17 also plays a vital role. Through the limiting effect of the guide wheel 17, the steel plate can maintain a certain distance from the fixed seat 16 during the rotation process, thereby preventing the contact wear between the steel plate and the fixed seat 16. This not only extends the service life of the equipment, but also ensures the quality of the surface of the steel plate. When the steel plate needs to be released, the motor 2 11 will start and drive the worm 12 to rotate. The worm 12 is connected to the support frame 2 through the worm gear 13, thereby driving the support frame 2 and the coil to rotate together. This transmission method has the advantages of compact structure, smooth transmission, low noise, etc., and can meet the requirements of modern industrial production for high precision and high efficiency. At the same time, the support frame 2 is limited in the limiting groove 3 by the limiting wheel 14 during the rotation process. This limiting method can ensure the stability and accuracy of the support frame 2 during the rotation process, thereby ensuring the stability and accuracy of the steel plate rotation.

[0043] Working principle: When the unwinding machine is used, first, the output end of the motor 1 5 drives the threaded rod 6 to rotate, and when the threaded rod 6 rotates, it drives the sleeve 7 to move toward the support frame 2, so that when the sleeve 7 moves, it drives the clamping plate 9 to unfold through the support rod 8, and the clamping plate 9 slides and limits in the limit groove 2 4 through the limit block 10, so that the coil is fixed when the clamping plate 9 is unfolded, and then the steel plate passes through the inside of the fixing seat 16, and the steel plate is fixed in the fixing seat 16 by the clamping block 19, and the clamping block 19 is extended and extended. The rod 18 is limited inside the fixed seat 16, and the clamping block 19 is supported by the tension of the spring 20 at the same time, so that the steel plate is clamped and fixed and will not move. At the same time, the steel plate will be limited by the guide wheel 17 to prevent the steel plate from contacting with the fixed seat 16 and causing wear. When the steel plate needs to be released later, the output end of the motor 2 11 drives the worm 12 to rotate, and the worm 12 drives the support frame 2 to rotate through the worm wheel 13, and then drives the coil to rotate. The support frame 2 is limited in the limiting groove 3 by the limiting wheel 14.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
