Description

Technical Field

[0001] This utility model relates to an unwinding device, and more particularly to an unwinding device for wrapping refractory mica tape. Background Technology

[0002] In the manufacturing process of electrical equipment such as cables and motors, fire-resistant mica tape is widely used as an important insulating material in the wrapping process. The mica tape unwinding device is one of the important components of the wrapping machine, and the quality of the mica tape unwinding will affect the efficiency of the wrapping machine and the product quality.

[0003] In existing unwinding devices, the position of the mica tape on the unwinding shaft may vary slightly due to minor changes during installation, transportation, or operation. However, the positions of downstream processing equipment (such as wrapping machines and stranding machines) are usually fixed. This results in a potential positional deviation between the mica tape leading from the unwinding shaft and the downstream equipment. This deviation not only affects the smooth transport of the mica tape but may also lead to misalignment and wrinkles during wrapping, thus impacting the insulation performance and appearance quality of the product. Traditional unwinding devices often lack effective adjustment mechanisms, making it difficult to quickly and accurately adjust when positional deviations are detected. This increases operational difficulty, prolongs adjustment time, and reduces production efficiency. Utility Model Content

[0004] To overcome the potential positional deviation between the mica tape led from the unwinding shaft and subsequent equipment, which not only affects the smooth transport of the mica tape but may also cause misalignment and wrinkles during the wrapping process, thus affecting the insulation performance and appearance quality of the product, traditional unwinding devices often lack an effective adjustment mechanism. This makes it difficult to quickly and accurately adjust when positional deviations are detected, which increases the difficulty of operation, prolongs the adjustment time, and reduces production efficiency. The objective is to provide an unwinding device for wrapping refractory mica tape to solve one of the above problems.

[0005] The technical solution of this utility model is: an unwinding device for refractory mica tape wrapping, comprising a mounting base, a lifting base, slide rails, a first transmission component, a first motor, a movable plate, a connecting base, a rotating disk, a material rack, a support plate, a sensor, a correction wheel, and a second motor. Two slide rails are vertically arranged on the front side of the mounting base, and a lifting base is slidably arranged between the slide rails. A first transmission component is mounted on the mounting base, consisting of a lead screw and a transmission motor. The lead screw of the first transmission component is screwed to the lifting base, driving the lifting base to move up and down on the slide rails. A first motor is vertically arranged at the lower part of the lifting base, and a movable plate is connected to the end of the output shaft of the first motor. The movable plate swings slightly left and right. A rotating disc is mounted on the movable plate, with a vertically mounted material rack for securing the mica tape roll. A connecting seat is located on the left side of the movable plate near the rotating disc, and a support plate is located on the right side of the mounting seat. A rotatable correction wheel is mounted on the front right side of the support plate, aligning with the material rack. The correction wheel has threads on its surface. A second motor is mounted on the rear right side of the support plate, with its output shaft fixedly connected to the correction wheel. Two opposing sensors are located on the front of the support plate, aligning with the correction wheel. During mica tape transmission, the tape passes through the area between the two sensors.

[0006] Furthermore, it also includes an arc-shaped guide rail, a slider, an arc-shaped spring, and an auxiliary wheel. An arc-shaped guide rail is provided on the upper right side of the support plate. A slider is slidably provided inside the arc-shaped guide rail. An auxiliary wheel is rotatably provided inside the slider. The auxiliary wheel is threaded. An arc-shaped spring is provided inside the arc-shaped guide rail. The two ends of the arc-shaped spring are connected to the top of the slider and the upper part of the arc-shaped guide rail, respectively. When the slider is at the lower limit position inside the arc-shaped guide rail, the auxiliary wheel and the correction wheel are on the same line in the vertical direction and are in contact with each other.

[0007] Furthermore, the spiral directions of the threads on the surfaces of the straightening wheel and the auxiliary wheel are opposite.

[0008] Furthermore, it also includes a cylinder, with the cylinder mounted on the support plate, the base of the cylinder hinged to the support plate, and the end of the cylinder's movable rod hinged to one side of the slider.

[0009] Furthermore, it also includes a lead roller. The support plate is rotatably provided with a lead roller near the mounting base. There are two lead rollers, which are staggered left and right and are not at the same horizontal level.

[0010] Furthermore, it also includes a fixed frame, a second transmission component, and an outlet component. The fixed frame is connected to the front side of the mounting base, and the second transmission component is mounted on the fixed frame. The mounting bases of the second transmission component are perpendicular to each other. The outlet component is equipped with an outlet component, and a guide wheel is rotatably mounted on the lower part of the outlet component. The guide wheel is aligned with the material rack. The outlet component moves back and forth under the drive of the second transmission component.

[0011] The present invention has the following advantages: The present invention is equipped with a mica tape unwinding frame that can swing to a certain extent, in conjunction with a correction wheel. By using a sensor that monitors the position deviation, the outward transmission of mica tape is straightened and corrected during unwinding, reducing the initial offset caused by various factors (such as material tension fluctuations, external interference, etc.), and reducing material waste and subsequent processing difficulties caused by skewness.

[0012] This invention utilizes an unwinding auxiliary guide mechanism to adjust the position of the guide wire according to the exit position of the master roll, making corresponding adjustments. This adjustment action is dynamic and continuous, ensuring that the guide wire always closely follows the exit position of the master roll, providing stable guidance and support for the mica tape.

Detailed Implementation

[0017] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0018] Example 1: An unwinding device for refractory mica tape wrapping, such as Figure 1-3As shown, the device includes a mounting base 1 and two vertically arranged slide rails 21 on the front side of the mounting base 1. These not only provide stable guidance for the lifting seat 2, but also allow the lifting seat 2 to move smoothly up and down along the slide rails 21 under the drive of the transmission component 22. The transmission component 22 consists of a precision lead screw and a transmission motor. They work together to ensure that the lifting seat 2 can be accurately positioned to the required height.

[0019] The motor 3, which is vertically mounted at the bottom of the lifting seat 2, is tightly connected to the movable plate 31 through its output shaft, giving the movable plate 31 a small swing capability in the left and right directions. This swing characteristic allows the rotating disk 32 and the material rack 321 on it to flexibly adjust their positions, thereby effectively dealing with the initial deviation that may occur during the unwinding of the mica tape. The material rack 321 is vertically set on the rotating disk 32, which not only firmly fixes the mica tape mother roll, but also ensures the stability and continuity of the mica tape during unwinding.

[0020] A connecting seat 311 is located on the left side of the movable plate 31 near the rotating disk 32. The connecting seat 311 is used to install the driving component that drives the rotating disk 32 to rotate. A support plate 4 is installed on the right side of the mounting seat 1. The straightening wheel 51 is rotatably mounted on the front right side of the support plate 4. Its surface is threaded. When the mica belt is transmitted outward, it needs to be in close contact with the surface of the straightening wheel 51. When the straightening wheel 51 rotates, the threads on it will cause the mica belt in contact with it to move forward or backward. The output shaft of the second motor 52 is fixedly connected to the straightening wheel 51, providing strong power support for the straightening wheel 51.

[0021] Two sensors 5 are positioned vertically opposite each other on the front side of the support plate. The sensors 5 are located in the area between the material rack and the correction wheel. During the transmission of the mica belt, the mica belt from the material rack 321 will pass to the right through the area between the sensors 5. The two sensors 5, which are positioned opposite each other, play a crucial role in monitoring the position and status of the mica belt in real time and providing accurate feedback signals to the correction system. When the mica belt deviates, the sensors 5 will immediately detect this change and trigger the correction mechanism. Driven by the motor 52, the correction wheel 51 will quickly adjust its angle or position and guide it back to the correct transmission path by slightly contacting the edge of the mica belt.

[0022] During the unwinding process of the mica tape, the movable plate 31 automatically fine-tunes its position through the transmission component 2 and the motor 3 according to the swing characteristics of the mica tape during unwinding to adapt to and reduce the initial deviation caused by various factors (such as material tension fluctuations, external interference, etc.). Subsequently, the correction wheel 51, with its high sensitivity and precise guiding effect, further finely adjusts the mica tape that has been initially straightened. This dual straightening and correction mechanism ensures that the mica tape remains straight and unbiased throughout the entire unwinding process.

[0023] Example 2: Based on Example 1, such as Figure 1 and Figure 3 As shown, an arc-shaped guide rail 6 is added to the upper right side of the support plate 4. This design allows the slider 61 to slide smoothly inside. The auxiliary wheel 63, which is rotatably set inside the slider 61, forms a cooperative relationship with the correction wheel 51. When the slider 61 slides down to the lower limit position of the arc-shaped guide rail 6, the auxiliary wheel 63 and the correction wheel 51 are just aligned and in contact with each other. The spiral directions of the threads on their surfaces are opposite. This design helps to further enhance the correction effect on the mica belt and prevent it from slipping or deviating during transmission.

[0024] The curved guide rail 6 contains a curved spring 62, one end of which is connected to the top of the slider 61, and the other end is fixed to the upper inner part of the curved guide rail 6. The presence of the curved spring 62 provides the slider 61 with a continuous upward thrust, ensuring that the auxiliary wheel 63 can maintain an appropriate distance from the correction wheel 51 in the non-working state, avoiding unnecessary friction and wear. When auxiliary correction is needed, the cylinder 64 will play a role. The base of the cylinder 64 is hinged to the support plate 4, and the end of its movable rod is hinged to one side of the slider 61. Through the extension and retraction of the cylinder 64, the up and down positions of the slider 61 and the auxiliary wheel 63 can be precisely controlled. At the same time, the correction wheel 51 can be lifted by the cylinder 64, so that when the mica belt is placed in the device, there is no need to manually pull the auxiliary wheel 63 apart, which facilitates operation and reduces the contact between the operator and the surfaces of the correction wheel 51 and the auxiliary wheel 63.

[0025] like Figure 1-2 As shown, two additional guide rollers 41 are added to the support plate 4. They are staggered left and right and their horizontal heights are not on the same line. The guide rollers 41 are used to initially guide and straighten the mica belt, as well as adjust the tension of the mica belt, to ensure that it is in a relatively straight state before entering the correction system, thereby reducing the working pressure of the subsequent correction rollers and improving the overall correction efficiency.

[0026] In addition, such as Figure 1-2 As shown, in order to further improve the flexibility and adaptability of the device, a fixed frame 7 is also connected to the front side of the mounting base 1. The fixed frame 7 is equipped with a transmission component 71, and the transmission component 71 is equipped with an outlet component 72. The transmission component 71 is perpendicular to the mounting base 1. This layout allows the outlet component 72 to move in the forward and backward direction under the drive of the transmission component 71. The lower part of the outlet component 72 is equipped with a rotating guide wheel, which is arranged in the same direction as the material rack 321. The transmission component 71 and the outlet component 72 can not only dynamically adjust the position of the lead wire according to the position of the tape exiting from the master roll, but also provide stable guidance and support for the mica tape, ensuring that it remains straight and unbiased during transmission.

[0027] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
