[0002] At present, the common winding method on the market is that the supply end uses an expansion shaft to string the rolled raw material on it, and then the inner diameter of the core is inflated by the shaft to provide winding damping; or the core punches the anti-rotation groove to stop the core from rotating to provide damping; the recovery end uses a motor to drive a cantilever tension shaft through a magnetic powder brake to keep the tension of the carbon ribbon constant. The common carbon ribbon winding method generally has the following disadvantages: 1. The tension shaft diameter has a minimum size limit of about 25mm. If the size of the supply end or the winding end is smaller than this size, the processing difficulty increases; and because of the complex process, small 1. It is difficult to buy finished products of the required size for use; 2. The magnetic powder brake is expensive and huge in size, which is difficult to meet the needs of small-scale production tools; 3. The way the paper shaft on the supply side punches the anti-rotation holes will cause wrinkles on the bottom layer of the carbon ribbon, affecting product quality; 4. The existing equipment is huge as a whole, with huge investment, and is mainly aimed at batch production of raw materials, and cannot meet the small-sized reeling requirements of downstream manufacturers; 5. After the reeling is completed, the reeling part and the reeled part are prone to looseness when the carbon ribbon is cut, affecting subsequent use.

DETAILED DESCRIPTION

[0027] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0028] like Figure 1-7 As shown, the utility model provides a technical solution: a carbon ribbon reeling machine, including a base 206, a frame guide rail 8 is installed on the base 206, and a right reeling slide 9 and a left reeling slide 5 are slidably arranged on the frame guide rail 8. The frame guide rail 8 can ensure that the left reeling slide 5 and the right reeling slide 9 can be slidably adjusted, so that they can adapt to carbon ribbons 13 of different widths, and the reeling position can also be adjusted. Secondly, through the replaceable chuck design, it can adapt to small-sized reel cores 15 and reel cores 15 of different shapes. The left reeling slide 5 is rotatably installed with a reeling active shaft 3 through a bearing, and the right reeling slide 9 is provided with a reeling passive shaft 10 through a shaft ring. A hand wheel 18 is arranged at one end of the reeling passive shaft 10. By pulling the hand wheel 18, the spring 203 on the reeling passive shaft 10 is deformed, and the reeling passive shaft 10 The displacement can realize the replacement of the winding core 15. After the hand wheel 18 is released, the spring 203 is reset to fix the winding core 15. The winding passive shaft 10 and the winding active shaft 3 are connected to the winding core 15 through a replaceable chuck 14. The replaceable chuck design can adapt to small-sized winding cores 15 and winding cores 15 of different shapes. The winding active shaft 3 is driven by a belt and a stepper motor 4. The stepper motor 4 can cooperate with the belt to drive the winding active shaft 3 to wind the carbon ribbon 13, and the stepper motor 4 can accurately control the number of rotations and ensure accurate control of the winding length. The stepper motor 4 is installed on the base 206. The base 206 is also equipped with a start switch 7 and an LED display screen 6. The LED display screen 6 with an adjustment function can conveniently adjust the winding length, working speed, and stepper motor 4 drive parameters;

[0029] The right winding slide 9 and the left winding slide 5 are both installed with a height bracket 12 by bolts. The height of the height bracket 12 can be adjusted by the bolts, and the height of the support shaft 11 can be adjusted to compensate for the manufacturing process error and avoid the tension imbalance caused by the non-parallel winding supply shaft 1, thereby causing the carbon ribbon 13 to wrinkle. The two height brackets 12 are slid with the support shaft 11, and the two height brackets 12 are installed with an elastic component 20. The elastic component 20 includes a fixed frame 205, and the fixed frame 205 is fixedly connected to the height bracket 12. Two groups of fixed blocks 201 are fixedly connected to the upper part of the fixed frame 205 and the fixed sleeve 194. The two groups of fixed blocks 201 are respectively hinged to the two connecting blocks 204 through pins, and a telescopic The rod 202 and the spring 203, after pressing the pressure plate 193 downward, make the spring 203 deform and turn downward, and the spring 203 can deform to maintain the position of the pressure plate 193 to prevent the pressure plate 193 from resetting. The number of each set of fixed blocks 201 is two, and the two elastic components 20 are equipped with a locking component 19 for fixing the carbon ribbon 13. The locking component 19 includes a telescopic frame 191. Through the telescopic feature of the telescopic frame 191, the height bracket 12 can be translated to drive the pressure plate 193 to expand and contract, and by pressing the pressure plate 193 downward, the arc surface of the pressure plate 193 presses the carbon ribbon 13 down to fit on the support shaft 11, thereby locking the position of the carbon ribbon 13. At this time, the carbon ribbon 13 can be cut off and processed to prevent the carbon ribbon 13 from rewinding. The telescopic frame 19 The two ends and the middle are respectively hinged with three pressing plates 193. The lower part of the pressing plate 193 is arc-shaped. The arc shape of the pressing plate 193 matches the support shaft 11. The arc-shaped setting of the pressing plate 193 can increase the contact area with the carbon ribbon 13, so that the carbon ribbon 13 can be pressed tightly. One side of the two outer pressing plates 193 is fixedly connected with a connecting shaft 192, and a fixing sleeve 194 is fixedly connected to the connecting shaft 192. The middle pressing plate 193 is hinged with two slide plates 197 through a pin shaft. A torsion spring 198 is fixedly connected between the two slide plates 197.

The torsion spring 198 is set outside the pin shaft. The torsion spring 198 is fixedly connected to both sides of the middle pressing plate 193. The slide plate 19 7 is arranged in the sleeve 196, and the sleeve 196 is fixed on the slide plate 197 by bolts. The sleeve 196 can slide to adjust the position of the pressure roller 195 to meet the actual use requirements. A pressure roller 195 is arranged between the two sleeves 196. As the thickness of the carbon ribbon 13 on the winding core 15 increases, the pressure roller 195 can be pressed on the carbon ribbon 13, so that the carbon ribbon 13 can be fixed to prevent the carbon ribbon 13 from loosening after winding. A magnetic damper 2 is installed on one side of the base 206. The magnetic damper 2 is linked to the belt to apply damping to the supply shaft 1, and the magnetic damper 2 has a knob for adjusting the damping, which can adjust the damping size of the supply shaft 1. The working principle of the magnetic damper 2 determines that the damping has almost no attenuation after long-term operation, ensuring the constant tension of the carbon ribbon 13.The magnetic damper 2 is driven by the supply shaft 1 through a belt. The supply shaft 1 is provided with a sleeve 17. The sleeve 17 is provided with a spring 16. The spring 16 is locked on the sleeve 17. The sleeve 17 is locked on the supply shaft 1. The spring 16 applies a damping anti-rotation force to the carbon ribbon 13 to ensure that the damping torque of the magnetic damper 2 can be converted into the winding tension. The carbon ribbon 13 is provided on the sleeve 17. The sleeve 17 is rotatably mounted on the base 206 through a bearing.

[0030] The working principle of the utility model is as follows: the operation of the stepper motor 4 can be controlled by starting the switch 7, and the stepper motor 4 drives the winding active shaft 3 through the belt to drive the core 15 to wind up the carbon ribbon 13, so that the supply shaft 1 releases the carbon ribbon 13 through the shaft sleeve 17, and the magnetic damper 2 applies resistance to the supply shaft 1 through the belt to release the carbon ribbon 13. After the winding of the core 15 is completed, the telescopic frame 191 is pressed down to drive the pressure plate 193 to press the carbon ribbon 13 onto the support shaft 11. At this time, the carbon ribbon 13 can be cut off in front of the support shaft 11, and the winding passive shaft 10 is driven to move by the hand wheel 18 to remove the core 15.
