[0001] The utility model relates to the technical field of composite insulating paper winding, in particular to a rotating shaft structure. Background Art

[0002] Insulating paper is a general term for electrical insulating paper, which is used as insulating material for various electrical equipment such as cables and coils.

After the production of insulating paper is completed, it needs to be wound into a roll using a winding core through the rotation of the shaft.

[0003] The existing composite insulating paper winding shaft structure is generally improved to address the problem of inconvenient disassembly of the shaft and the winding core. For example, the authorized Chinese patent CN216945695U discloses a composite insulating paper winding shaft, which can be easily disassembled by using a fixed shaft, a fixed block, a connecting strip, a movable block, a strap, a limit plate, a fixing screw, a pull rod, a pull plate and a second threaded hole. The structure achieves the purpose of facilitating the removal of the shaft.

[0004] However, when the rotating shaft structure in the above-mentioned cited document is disassembled after winding, each fixing screw needs to be unscrewed one by one, and then the pull plate is manually pulled to pull out the four connecting strips one by one, so that the wound composite insulating paper can be taken out. The operation is complicated, time-consuming and labor-intensive, resulting in the use effect of the existing rotating shaft structure to be improved. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3The utility model provides a technical solution: a rotating shaft structure for composite insulating paper winding, comprising a fixed shaft 1, the fixed shaft 1 is provided with four movable grooves 3 evenly distributed in a ring shape with the center of the fixed shaft 1 as the axis, a tension adjustment mechanism 200 is installed in the fixed shaft 1, and the tension adjustment mechanism 200 is used to increase the tightness when the composite insulating paper is wound and shrink it when it is taken out;

[0025] By using the tension adjustment mechanism 200 on the fixed shaft 1 in coordination with each other, the composite insulating paper can be closely fitted to the rotating shaft when winding to prevent sliding and loose winding. At the same time, the wound insulating paper can be conveniently removed, which is simple to operate and can greatly improve the efficiency of winding, thereby effectively improving the use effect of the existing rotating shaft structure.

[0026] In this embodiment, the tension adjustment mechanism 200 is a structure that can increase the tightness when winding and shrink when taking out.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the tension adjustment mechanism 200 includes a driving component installed at the center of one side of the fixed shaft 1 and a driving cylindrical gear 202 installed on the outside of the driving component. Four driven cylindrical gears 203 are meshed on the outside of the driving cylindrical gear 202, and the driven cylindrical gears 203 are evenly distributed in a ring shape with the center of the fixed shaft 1 as the axis. The driven cylindrical gear 203 is connected to the driving component through the driving cylindrical gear 202. Under the drive of the driving component, the four driven cylindrical gears 203 meshed on the driving cylindrical gear 202 are driven to rotate in the same direction at the same time. A bidirectional threaded rod 204 that penetrates into the moving groove 3 is fixedly connected to the side of the driven cylindrical gear 203 close to the fixed shaft 1. Two groups of adjustment components are connected to the outside of the bidirectional threaded rod 204, and the two groups of adjustment components are distributed in a mirror-symmetrical manner. A connecting rod component is connected to one side of the adjustment component, and an arc-shaped strap 208 is installed between the two connecting rod components on the side away from the moving groove 3.

[0028] It should be noted that the driving assembly includes a rotating rod 2011 and a rotating handle 2012; one end of the rotating rod 2011 is fixedly connected to the center of one side of the rotating handle 2012, and the other end penetrates the active cylindrical gear 202 and is rotatably connected to the center of one side of the fixed shaft 1 through a bearing. When the rotating handle 2012 is rotated, the rotating rod 2011 can be driven to rotate, thereby driving the four driven cylindrical gears 203 meshed on the active cylindrical gear 202 to rotate at the same time, so as to be able to drive the bidirectional threaded rod 204 to rotate, thereby driving the two adjustment assemblies to move.

[0029] It can be understood that the adjustment assembly includes a moving block 2051 and an adjustment block 2052; the inner thread of the moving block 2051 is connected to the outer side of the bidirectional threaded rod 204, and the outer side of the moving block 2051 slides in contact with the inner side of the moving groove 3, and the side of the adjustment block 2052 away from the arc-shaped strap 208 is fixedly connected to one side of the moving block 2051; the moving block 2051 moves on the outer side of the bidirectional threaded rod 204 under the thrust of the rotation of the inner thread, and drives the adjustment block 2052 to move, in order to drive the connecting rod assembly to move, so as to drive the arc-shaped strap 208 to move.

[0030] In addition, an adjustment hole 206 for the adjustment block 2052 to slide against is opened on one side of the movable groove 3 close to the arc-shaped strap 208, so as to make the adjustment block 2052 move more stably.

[0031] In this embodiment, the connecting rod assembly includes a No. 1 hinge seat 2071, a hinge rod 2072 and a No. 2 hinge seat 2073; one end of the hinge rod 2072 is hinged to the inner side of the No. 1 hinge seat 2071 through a pin shaft, and the other end is hinged to the inner side of the No. 2 hinge seat 2073 through a pin shaft. The side of the No. 1 hinge seat 2071 close to the movable groove 3 is fixedly installed on one side of the adjustment block 2052, and the side of the No. 2 hinge seat 2073 away from the movable groove 3 is fixedly installed on the arc-shaped bridge plate. On one side of 208; when the two adjustment blocks 2052 move in opposite directions, the two No. 1 hinge seats 2071 can be driven to move in opposite directions, driving the hinged rod 2072 to move close to the end of the movable groove 3, and pushing the No. 2 hinge seat 2073 connected to the end of the hinged rod 2072 away from the movable groove 3 to move vertically, so as to push the arc-shaped strap 208 to move, in order to increase the tightness during winding, and to shrink it when taking it out.

[0032] It should also be noted that the side of the bidirectional threaded rod 204 away from the driven cylindrical gear 203 passes through the two moving blocks 2051 and extends to the inner wall of the moving groove 3 and is rotatably connected to the moving groove 3 through a bearing, so as to make the rotation of the bidirectional threaded rod 204 more stable.

[0033] It should be further explained that the left half of the bidirectional threaded rod 204 is a left-handed thread, and the right half of the bidirectional threaded rod 204 is a right-handed thread, so that when the bidirectional threaded rod 204 rotates, it can simultaneously drive the two moving blocks 2051 to move at a uniform speed in opposite directions.

[0034] The working principle of the above embodiment is:

[0035] Before winding the composite insulating paper, hold the handle 2012 and rotate it. Under the rotation support of the bearing, the rotating rod 2011 is driven to rotate, so as to drive the four driven cylindrical gears 203 meshed on the active cylindrical gear 202 to rotate in the same direction at the same time. Then, the bidirectional threaded rod 204 is driven to rotate under the rotation support of the bearing. Since the moving block 2051 can only move in the moving groove 3, the two moving blocks 2051 move at a uniform speed in opposite directions on the outside of the bidirectional threaded rod 204 under the thrust of the inner thread rotation. Since the adjusting block 2052 can only move in the adjusting hole 206, when the moving block 2051 moves, the adjusting block 2052 can be driven to move stably, and the No. 1 hinge seat can be driven. 2071 moves, and then drives the two hinged rods 2072 to move in opposite directions at one end close to the moving groove 3, and pushes the second hinge seat 2073 connected to the end of the hinged rod 2072 away from the moving groove 3 to move vertically, so as to push the arc-shaped strap 208 to move. It is only necessary to push the arc-shaped strap 208 to move a suitable distance to open the four arc-shaped straps 208, and then wind the composite insulating paper on the outside of the arc-shaped strap 208, and open the arc-shaped strap 208 again by the above principle, so that the composite insulating paper can be closely fitted with the rotating shaft when winding. When the wound composite insulating paper needs to be taken out after the winding is completed, the wound insulating paper can be conveniently taken out by reverse operation according to the above principle.

[0036] Compared with the prior art: the composite insulating paper winding shaft structure, through the mutual cooperation between the tension adjustment mechanism 200 on the fixed shaft 1, can be closely fitted with the shaft when the composite insulating paper is wound to prevent sliding and loose winding. At the same time, the wound insulating paper can be conveniently removed, the operation is simple, and the efficiency of winding can be greatly improved, thereby effectively improving the use effect of the existing shaft structure, and solving the problem that the existing shaft structure is not convenient for quickly taking the wound composite insulating paper.
