Description

Technical Field

[0001] The utility model relates to the technical field of mica cloth unwinding, in particular to a mica cloth unwinding device. Background Art

[0002] The natural mica used in mica cloth is decomposed by nanotechnology and then woven with textile fibers to form a mat fabric. Mica cloth has good insulation performance, high temperature resistance performance and mechanical performance, is not easy to age and deform, and at the same time has good corrosion resistance and can withstand many different chemical media. During the processing of mica cloth, it needs to be cut into a certain length according to requirements, and a unwinding device is used for support and unwinding during the cutting process.

[0003] The patent with the application number 202322497913.6 discloses a glass fiber cloth unwinding device, which includes a frame. On both sides of the frame, mounting grooves are symmetrically fixed. A unwinding shaft is placed between the two mounting grooves. One side of the unwinding shaft is fixed with a speed limiting disk. A braking device cooperating with the speed limiting disk is also arranged on the frame. The braking device includes a brake block. One end of the brake block is fixed with a connecting plate. A spring is also arranged between the connecting plate and the frame. The inertia rotation of the unwinding shaft due to the pulling of the glass fiber cloth can be avoided by the friction force between the brake block and the speed limiting disk when the conveying device stops.

[0004] Although the above technical solution solves the problem of the continuous rotation of the unwinding shaft due to inertia through the brake block, the mica cloth will droop after cutting, and since the brake block cannot ensure that the unwinding shaft is completely in the axially positioned state, the continuous increase of the drooping mica cloth will occur during the storage process of the unwinding shaft, resulting in poor storage effect of the cut mica cloth. Content of the Utility Model

[0005] The purpose of the utility model is to provide a mica cloth unwinding device for the deficiencies of the prior art. The functions of axially moving the rotating shaft and mica cloth and fixing the opening of the mica cloth are realized by the rotating shaft arranged in the support block and the axially positioning rod structure clamped with the damping block on the rotating shaft and the adjustable lifting plate structure, solving the problem of poor storage effect of the cut mica cloth.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A mica unwinding device, comprising a base and a rotating shaft disposed above the base. Both sides of the top surface of the base are fixedly provided with support rods, and a lifting plate located below the rotating shaft is adjustably installed on the base. Support blocks are fixedly provided on the side walls of both support rods. A mica fabric is fixedly sleeved at the central position of the rotating shaft, and damping rings are installed at both ends of the rotating shaft. A plurality of positioning holes are formed in an annular array on the outer wall of the damping ring, and an axial positioning rod detachably installed at the top of the support rod is clamped with the positioning holes.

[0007] Preferably, fixed rods are installed on both sides of the top surface of the base, and lifting rods slidably inserted into fixed tubes are fixedly provided on both sides of the bottom surface of the lifting plate.

[0008] Further, a rotating tube is installed through a bearing at the central position of the top surface of the base, and a screw rod fixed to the lifting plate is threadedly inserted at the top of the rotating tube.

[0009] Furthermore, an arc-shaped groove is formed in the inner wall of the lifting plate, and a knob is fixedly sleeved on the rotating tube.

[0010] Furthermore, the axial positioning rod is in a U-shaped structure and is inserted into the positioning hole in a fitting manner, and a rotating rod is installed on the axial positioning rod.

[0011] Furthermore, a threaded hole is formed at the top of the support rod, and the bottom end of the rotating rod is threadedly inserted into the threaded hole.

[0012] Furthermore, positioning plates are fixedly sleeved at both ends of the rotating shaft, and the positioning plates are in contact with the inner walls of the support blocks.

[0013] Furthermore, both ends of the rotating shaft are embedded in the support blocks, and the damping blocks on the rotating shaft are tightly connected to the inner walls of the support blocks.

[0014] The beneficial effects of the present utility model are as follows:

[0015] (1) In the present utility model, a mica fabric is fixed on the rotating shaft, and the positioning plates at both ends of the rotating shaft are in contact with the support blocks, avoiding the problem of lateral movement of the rotating shaft during the unwinding process. At the same time, a threaded hole is formed in the support rod, the rotating rod is threadedly inserted into the threaded hole, and the damping blocks improve the friction of the mica fabric conveying, reduce the inertia of the rotating shaft rotation. During the movement, the axial positioning rod is inserted into the positioning hole on the outer wall of the damping block, so that the rotating shaft and the mica fabric maintain axial positioning, improving the convenience of axial positioning after the mica fabric is cut.

[0016] (2) In the present utility model, a lifting plate is provided above the base. After the mica fabric is axially positioned, the rotating tube is driven to rotate by a knob, and during the rotation, the screw rod drives the lifting plate to move upward. The lifting rod moves synchronously within the fixed rod, and during the movement, the arc-shaped groove on the inner wall of the lifting plate abuts against the opening of the mica fabric, thereby preventing the mica fabric from sagging after cutting.

[0024] Embodiment 1

[0025] As Figure 1 and Figure 3 As shown, this embodiment provides a mica unwinding and rewinding device, including a base 1 and a rotating shaft 7 arranged above the base 1. Both sides of the top surface of the base 1 are fixedly provided with support rods 6, and a lifting plate 2 located below the rotating shaft 7 is adjustably installed on the base 1. Support blocks 3 are fixedly provided on the side walls of the two support rods 6. A mica fabric 4 is fixedly sleeved at the central position of the rotating shaft 7, and damping rings 17 are installed at both ends of the rotating shaft 7. A plurality of positioning holes 18 are formed in an annular array on the outer wall of the damping ring 17. An axial positioning rod 5 that is detachably installed at the top of the support rod 6 and is clamped with the positioning hole 18 is provided.

[0026] An arc-shaped groove 13 is formed in the inner wall of the lifting plate 2. A knob 10 is fixedly sleeved on the rotating tube 11. The axial positioning rod 5 is in a U-shaped structure and is inserted into the positioning hole 18 in a fitting manner, and a rotating rod 14 is installed on the axial positioning rod 5. A threaded hole 15 is formed at the top of the support rod 6. The bottom end of the rotating rod 14 is threadedly inserted into the threaded hole 15. When the rotating rod 14 is threadedly inserted into the threaded hole 15, the damping block improves the friction force of the mica fabric 4 during conveying and reduces the inertia of the rotating shaft 7 rotating. During the movement process, the axial positioning rod 5 is inserted into the positioning hole 18 on the outer wall of the damping block, so that the rotating shaft 7 and the mica fabric 4 maintain axial positioning.

[0027] Embodiment 2

[0028] As Figure 2 and Figure 4As shown in the figure, the same or corresponding components as those in the first embodiment are marked with the corresponding reference numerals of the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between the second embodiment and the first embodiment is that positioning plates 16 are fixedly sleeved at both ends of the rotating shaft 7. The positioning plates 16 are in contact with the inner wall of the support block 3. The positioning plates 16 at both ends of the rotating shaft 7 are in contact with the support block 3, which avoids the problem of lateral movement of the rotating shaft 7 during the unwinding process. Both ends of the rotating shaft 7 are embedded in the support block 3, and the damping blocks on the rotating shaft 7 are tightly connected to the inner wall of the support block 3. Fixed rods 9 are installed on both sides of the top surface of the base 1. Lifting rods 8 fixedly connected to both sides of the bottom surface of the lifting plate 2 are slidably inserted into the fixed tubes. A rotating tube 11 is installed at the center position of the top surface of the base 1 through a bearing. A screw rod 12 fixed to the lifting plate 2 is threadedly inserted into the top end of the rotating tube 11.

[0029] Working steps

[0030] Step 1: At the same time, screw holes 15 are formed in the support rod 6, and the rotating rod 14 is threadedly inserted into the screw holes 15. The damping blocks increase the friction of the mica fabric 4 during transportation and reduce the inertia of the rotation of the rotating shaft 7. During the movement, the axial positioning rod 5 is inserted into the positioning holes 18 on the outer wall of the damping block, so that the rotating shaft 7 and the mica fabric 4 are axially positioned. After the mica fabric 4 is axially positioned, the rotating tube 11 is rotated by the knob 10, and during the rotation, the screw rod 12 drives the lifting plate 2 to move upward. The lifting rods 8 move synchronously in the fixed rods 9, and during the movement, the arc-shaped grooves 13 on the inner wall of the lifting plate 2 are abutted against the opening of the mica fabric 4, thereby avoiding the situation that the mica fabric 4 droops after being cut.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
