Description

TECHNICAL FIELD

[0001] The utility model relates to the field of encapsulation technology, especially to a ferrite encapsulation tool. BACKGROUND

[0024] It needs to be explained that: in use, the rubber strip fixing roll is arranged on the rubber roller 2, and the damping force is set by tightening the locking bolt 4, so that the rubber roller 2 has a certain damping force, and the damping force needs to be overcome to rotate. During use, first, the ferrite is placed on the rotating disc 10, the trapezoidal screw rod 23 is rotated, the two nut blocks 24 are brought close to each other, the two nut blocks 24 drive the two symmetrically arranged limiting blocks 20 to move close to each other, and the movement of the two limiting blocks 20 drives the rotation of the driving disc 25 through the two rotatingly connected L-shaped driving rods 21, the rotation of the driving disc 25 drives the other two symmetrically arranged limiting blocks 20 to move close to each other through the corresponding L-shaped driving rods 21, so that by rotating the trapezoidal screw rod 23, the four arc-shaped clamping blocks 12 can be brought close to the center of the rotating disc 10 to stably clamp the ferrite, and then the trapezoidal screw rod 23 is self-locked to complete the fixation. Then the rubber strip is wound around the tensioning mechanism and fixed to the surface of the ferrite, and then the rotation of the shaft 17 is driven by the rotation of the motor 16, so that the circular plate 18 drives the rotating disc 10 to rotate, and then the ferrite rotates, so that the rubber strip is wound and attached to the surface of the ferrite. After the attachment is completed, the motor 16 is turned off, the rubber strip is cut, and then the trapezoidal screw rod 23 is reversed to release the clamping and take down the ferrite.

[0025] It needs to be further explained that: during use, the rubber roller 2 needs to overcome the damping force to rotate, so that the rubber strip can maintain a certain tension during the winding and attaching process.

[0026] Reference Figure 1 and Figure 2 As shown in the figure, the tensioning mechanism includes a telescopic rod 13, a spring 14, a sliding block 15 and a tensioning roller 5.

[0027] It needs to be explained that: during use, the tensioning roller 5 is pushed to make the sliding block 15 extrude the telescopic rod 13 and the spring 14, so that the telescopic rod 13 is contracted and the spring 14 is compressed. Then the rubber strip is wound around the tensioning roller 5 and attached to the ferrite at the other end. During the winding and attaching process of the rubber strip, when the rubber strip is loose, the elastic force of the spring 14 can push the sliding block 15 to translate, so that the tensioning roller 5 translates to extrude the rubber strip and keep the rubber strip tight.

[0028] Reference Figure 4 As shown in the figure, the trapezoidal screw rod 23 is fixedly connected with a matching hexagonal knob 28 at one end of the fixed block 22. The hexagonal knob 28 is arranged to facilitate the rotation of the trapezoidal screw rod 23.

[0029] Reference Figure 1As shown, the upper surface of the base 1 is provided with four evenly distributed electric heating pipes 8 around the mounting groove 9. The electric heating pipes 8 can uniformly heat and soften the adhesive tape during winding, greatly improving the fitting quality and firmness.

[0030] Referring to Figure 1 As shown, one side of the electric heating pipe 8 is provided with a matching arc-shaped aluminum foil reflecting plate 7, which is fixedly connected with the upper surface of the base 1. The arc-shaped aluminum foil reflecting plate 7 can block the disorderly diffusion of heat, improve the heat efficiency, and ensure safety.

[0031] Referring to Figure 1 As shown, the upper surface of the base 1 is further rotationally connected with a guide roller 6, which is concentric with the parallel axis of the rotating disc 10. After passing through the tensioning roller 5, the adhesive tape is fixed on the ferrite after passing through the guide roller 6, which plays a guiding role.

[0032] Referring to Figure 4 As shown, two slide rods 27 parallel to the trapezoidal screw rod 23 are fixedly connected between the two fixed blocks 22, and the nut block 24 is slidingly sleeved on the two slide rods 27. The slide rods 27 serve as a limiting part, making the translation of the nut block 24 more stable.

[0033] The working principle of the utility model is as follows: when using, the adhesive tape is fixed on the rubber roller 2, and then the damping force is set by screwing the locking bolt 4, so that the rubber roller 2 has a certain damping force, and needs to overcome the damping force to rotate. During use, first, the ferrite is placed on the rotating disc 10, the trapezoidal screw rod 23 is rotated, the two nut blocks 24 driven by the trapezoidal screw rod 23 are close to each other, the two limit blocks 20 symmetrically arranged and driven by the two nut blocks 24 are close to each other, the movement of the two limit blocks 20 drives the rotation of the driving disc 25 through the two rotatingly connected L-shaped driving rods 21, the rotation of the driving disc 25 drives the other two limit blocks 20 symmetrically arranged to be close to each other through the corresponding L-shaped driving rods 21, so that the four arc-shaped clamping blocks 12 can be close to the center of the rotating disc 10 by rotating the trapezoidal screw rod 23, the ferrite is clamped stably, then the fixing is completed through the self-locking property of the trapezoidal screw rod 23, then the adhesive tape is wound around the tensioning mechanism and fixed on the surface of the ferrite, then the rotation of the rotating shaft 17 driven by the rotation of the motor 16 drives the rotating disc 10 to rotate through the circular plate 18, and then the ferrite is rotated, so that the adhesive tape is wound and attached to the surface of the ferrite, after the attachment is completed, the motor 16 is turned off, the adhesive tape is cut, and then the trapezoidal screw rod 23 is reversed, the ferrite is released and taken off. The rotating clamping mechanism arranged in the device can make the four arc-shaped clamping blocks 12 close to the center of the rotating disc 10 at the same time to clamp and fix the ferrite, and then the adhesive tape is attached, so that the ferrite of different diameters can have stable and appropriate clamping force, and slipping or damage is avoided, so that the stability during the operation of the device is improved, and the applicability is improved. During use, the rubber roller 2 needs to overcome the damping force to rotate, so that the adhesive tape can be kept tight during the winding and attachment process, the winding and attachment of the adhesive tape can be tighter, and the quality of the ferrite encapsulation is improved. During use, the tensioning roller 5 is pushed, the sliding block 15 extrudes the telescopic rod 13 and the spring 14, the telescopic rod 13 is contracted, and the spring 14 is compressed, then the adhesive tape is wound around the tensioning roller 5, and the other end is attached and fixed to the ferrite. During the winding and attachment process of the adhesive tape, when the adhesive tape is loose, the elastic force of the spring 14 can push the sliding block 15 to translate, the tensioning roller 5 is translated, the adhesive tape is extruded, the adhesive tape is kept tight, so that the winding and attachment of the adhesive tape can be tighter, and the quality of the ferrite encapsulation is further improved.
