Description

Technical Field

[0001] The utility model relates to the technical field of diamond-shaped glue-dotting paper winding, in particular to an automatic tension control device for diamond-shaped glue-dotting paper special for transformers. Background Art

[0002] Transformer-specific diamond-shaped dotted paper is a special insulating material widely used in interlayer insulation and interturn insulation of oil-immersed power transformers. After production, the diamond-shaped dotted paper needs to be reeled. During reeling, a certain tension needs to be applied to the diamond-shaped dotted paper to ensure that the diamond-shaped dotted paper can be wound flatly on the reel to avoid unevenness or wrinkles on the roll surface. During the reeling process, as the thickness of the reel increases, the tension needs to be slowly reduced. This is because the roll diameter of the material roll is slowly increasing during the reeling process. Currently, the required tension is mainly adjusted by adjusting the position of the tension roller.

[0003] The current automatic tension control device detects the changes in the thickness of the winding roller and the tension of the winding material during the winding process through a variety of internal sensors, and transmits them to the control box. The control box controls the relevant electrical equipment to adjust the position of the tension roller to change the tension. The adjustment accuracy is high, but the overall cost of the device is relatively high. It is suitable for the winding of yarn-like materials that are easy to break. Diamond-shaped dotted paper has good toughness and is relatively strong. Unlike yarn-like materials, it does not require more precise control of its tension when winding. It only needs to give a certain tension and slowly reduce the tension as the diamond-shaped dotted paper is wound. For this reason, we propose a transformer-specific diamond-shaped dotted paper automatic tension control device, which has low cost and is more suitable for the winding of diamond-shaped dotted paper.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-6 The utility model provides an automatic tension control device for diamond-shaped dotted glue paper specially used for transformers, comprising: a mounting frame 1, fixing bolts 2 fixed to the four corners of the bottom inner wall of the mounting frame 1, and a winding roller 3 installed on the inner wall of one side of the mounting frame 1, and also comprising: a telescopic component 4 installed at one end of the top inner wall of the mounting frame 1, an elastic component 5 installed at the other end of the top inner wall of the mounting frame 1, and a first frame 6 installed at the bottom of the elastic component 5, a tension roller 7 rotatably installed on the inner wall of the first frame 6, and a linkage component 8 fixed to the outer wall of the telescopic component 4, and a limiting component 9 installed at the other end of the top inner wall of the mounting frame 1.

[0022] It should be noted here that the diamond-shaped dotted paper 10 can be wound up by the winding roller 3. During the winding process, the diamond-shaped dotted paper 10 passes under the tension roller 7. The elastic component 5 presses the tension roller 7 on the diamond-shaped dotted paper 10, so that the diamond-shaped dotted paper 10 is straightened between the tension roller 7 and the winding roller 3, giving the diamond-shaped dotted paper 10 a certain tension so that the diamond-shaped dotted paper can be wound flatly on the winding roller 3. As the winding proceeds, the thickness of the diamond-shaped dotted paper roll on the surface of the winding roller 3 slowly increases, pushing the telescopic component 4 upward, and the telescopic component 4 moves upward to drive the linkage component 8 to move upward, and the linkage component 8 moves upward, driving the first frame 6 to move upward to squeeze the elastic structure in the elastic component 5, and driving the tension roller 7 to move upward, slowly reducing the tension applied to the diamond-shaped dotted paper 10. During the upward movement of the linkage component 8, the limit component 9 automatically limits its upward movement, so that the linkage component 8 can only move upward and cannot descend. Through the design of the mechanical structure, this device can give a certain tension when the diamond-shaped dotted paper 10 is rolled up, and automatically control to reduce the tension as the diamond-shaped dotted paper 10 is rolled up. There is no need to use various sensors and electrical equipment. The overall cost of the device is low, and it is more suitable for the rolling of the diamond-shaped dotted paper 10.

[0023] In a preferred embodiment, the telescopic assembly 4 includes a fixed tube 401 , a movable rod 402 slidably connected to the inner wall of the fixed tube 401 , a second frame 403 installed at the bottom of the movable rod 402 , and a lifting roller 404 rotatably installed on the inner wall of the second frame 403 .

[0024] It should be noted here that: the lifting roller 404 is affected by gravity and presses on the diamond-shaped dotted paper 10 when the diamond-shaped dotted paper 10 is rolled up. As the rolling thickness increases, the lifting roller 404 is pushed upward, thereby driving the movable rod 402 to rise and move into the fixed tube 401. The rise of the movable rod 402 drives the linkage assembly 8 to rise.

[0025] In a preferred embodiment, the elastic component 5 includes a long rod 502 and a spring 501 sleeved on the upper portion of the outer wall of the long rod 502 .

[0026] It should be noted here that the linkage assembly 8 rises to compress the spring 501 .

[0027] In a preferred embodiment, the linkage assembly 8 includes a bending plate 801, a fixing hole 802 opened at one end of the top outer wall of the bending plate 801, an insertion hole 803 opened at the other end of the top outer wall of the bending plate 801, and a bevel rack 804 fixed on the outer wall of one side of the bending plate 801.

[0028] It should be noted here that: the movable rod 402 rises to drive the bending plate 801 to rise, and the bending plate 801 is sleeved on the outside of the long rod 502 through the insertion hole 803. The bending plate 801 rises and squeezes the spring 501.

[0029] In a preferred embodiment, the limiting assembly 9 includes an L-shaped plate 901, a connecting frame 902 installed on the L-shaped plate 901, a clamping plate 903 rotatably installed on the inner wall of the connecting frame 902, and a tension spring 904 connected to the outer wall of one side of the clamping plate 903, and the tension spring 904 is connected to the L-shaped plate 901 at one end away from the clamping plate 903.

[0030] It should be noted here that: the rising of the bending plate 801 drives the bevel rack 804 to rise, and the bevel rack 804 rises, continuously pushing the card plate 903 to the side of the L-shaped plate 901. Under the action of the tension spring 904, the card plate 903 is continuously reset, so that the card plate 903 does not affect the rising of the bevel rack 804 and continuously presses between the bevel teeth of the bevel rack 804, so that the bending plate 801 will not slide down.

[0031] In a preferred embodiment, the fixing hole 802 is fixed to the outer wall of the movable rod 402 , and the long rod 502 is inserted through the insertion hole 803 , and the bottom of the bending plate 801 is fixedly connected to the top of the first frame 6 .

[0032] It should be noted that the movement of the movable rod 402 can drive the bending plate 801 to move, and the movement of the bending plate 801 can drive the first frame 6 to move.

[0033] Working principle: The diamond-shaped dotted paper 10 can be wound up by the winding roller 3. During the winding process, the diamond-shaped dotted paper 10 passes under the tension roller 7. During the winding process, the diamond-shaped dotted paper 10 pushes the tension roller 7 upward, and the tension roller 7 drives the bending plate 801 to squeeze the spring 501. The tension roller 7 is pressed against the diamond-shaped dotted paper 10 through the reaction force of the spring 501, so that the diamond-shaped dotted paper 10 is straightened between the tension roller 7 and the winding roller 3, giving the diamond-shaped dotted paper 10 a certain tension, so that the diamond-shaped dotted paper can be wound flatly on the winding roller 3;

[0034] The lifting roller 404 is pushed upward by the action of the tension spring 904, so that the card plate 903 does not affect the rising of the bevel rack 804 and constantly presses between the bevel teeth of the bevel rack 804, so that the bending plate 801 will not slide down.

[0035] The bending plate 801 rises, driving the first frame 6 to rise, and driving the tension roller 7 to rise, slowly reducing the tension applied to the diamond-shaped dotted paper 10. Through the design of the mechanical structure, this device can give a certain tension when the diamond-shaped dotted paper 10 is rolled up, and automatically control to reduce the tension as the diamond-shaped dotted paper 10 is rolled up. There is no need to use various sensors and electrical equipment. The overall cost of the device is low, and it is more suitable for the use of the diamond-shaped dotted paper 10 when it is rolled up.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
