Description

Technical Field

[0001] This utility model relates to the technical field of mica winding device for tower trays, specifically an automatic tension adjustment device for mica belts on tower trays. Background Technology

[0002] Tower-type mica tape is a large-roll, high-performance mica insulation material specifically designed for large-scale continuous production. Through a special structure and process, it achieves ultra-long continuous lengths and is primarily used as the insulation layer for fire-resistant wires and cables to meet the demands of high-efficiency production and high-end electrical performance. During production, the mica tape needs to be cut according to width requirements, and then wound up using a winding device. An automatic tension adjustment device is installed on the outside of the winding device, applying a constant, controllable, and appropriate tensile force to the mica tape throughout the winding process, thereby ensuring winding quality and laying the foundation for subsequent high-speed, stable unwinding applications.

[0003] Automatic tension regulating equipment is divided into active and passive types. Compared with passive automatic tension regulating equipment, active automatic tension regulating equipment has higher system complexity and cost, and requires higher technical skills from operators and maintenance personnel. It is also susceptible to electrical interference and power grid quality. Furthermore, electrically driven active tension regulating equipment causes greater wear on mechanical parts. Once a fault occurs, the mica tape is prone to sudden breakage. In addition, mica tape winding is a continuous process. When a set of tower trays has wound a certain thickness of mica tape, the winding position of the mica tape needs to be adjusted. At this time, the equipment needs to be stopped, which greatly reduces the winding speed of the mica tape.

[0004] To address these issues, this invention provides an automatic tension adjustment device for the mica belt on a tower tray. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic tension adjustment device for mica belts on tower trays, which solves the aforementioned problems.

[0011] Preferably, a limiting frame is installed on the outer side of the guide wheel A and the guide wheel B, and a limiting rod is symmetrically rotatably connected inside the limiting frame.

[0012] Beneficial effects

[0013] This invention provides an automatic tension adjustment device for mica belts on a tower tray. Compared with the prior art, it has the following advantages:

[0014] This automatic tension adjustment device for mica tape in a tower tray automatically adjusts the tension of the mica tape during winding by using the torque generated by the torsion spring installed between the connecting seat and the rotating rod. This prevents the mica tape from breaking due to excessive winding and avoids deformation and scattering due to excessive loose winding. The tension adjustment is fast and the installation cost is low. During continuous winding of the mica tape, the reciprocating screw connected to the output end of the servo motor drives the movement of the guide wheel A and guide wheel B to adjust the winding position of the mica tape without the need for machine downtime, thus improving the winding efficiency of the mica tape.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figure 1-3 An automatic tension adjustment device for a mica belt on a tower tray includes an equipment box 1, a conveyor 2 and an installation rod 3 installed on the outside of the equipment box 1, a tension adjustment component 4 installed on the top of the installation rod 3, a mica belt 5 wound between the conveyor 2 and the tension adjustment component 4, and an air shaft 6 installed on the outside of the equipment box 1.

[0022] The tension adjusting component 4 includes a connecting seat 401 installed on the outside of the mounting rod 3, an inclined rod 402 at the top of the connecting seat 401, a transmission wheel A403 and an auxiliary wheel A404 rotatably connected to the outside of the inclined rod 402, a rotating rod 405 hinged to the outside of the connecting seat 401, a transmission wheel B406 rotatably connected to the outside of the rotating rod 405, a support rod 407 fixedly connected to the outside of the rotating rod 405, an auxiliary wheel B408 rotatably connected to the outside of the support rod 407, a sleeve rod 409 fixedly connected to the outside of the connecting seat 401, a torsion spring 4010 installed on the outside of the sleeve rod 409, and the two ends of the torsion spring 4010 installed on the outside of the connecting seat 401 and the support rod 407.

[0023] A reciprocating moving part 7 is installed on the outer side of the mounting rod 3.

[0024] The conveying component 2 includes a crossbar 201 fixedly connected to the outside of the equipment box 1, a feed wheel 202 rotatably connected to the outside of the crossbar 201, a conveying wheel A203 and a conveying wheel B204 rotatably connected to the outside of the equipment box 1, and a conveying wheel C205 rotatably connected to the outside of the connecting seat 401.

[0025] In this embodiment, the slit mica ribbon 5 passes through the feed wheel 202 outside the crossbar 201, and is pulled to wrap around the outside of the conveyor wheels A203, B204 and C205. Then, the mica ribbon 5 is wrapped around the outside of the guide wheel A403, auxiliary wheel A404, guide wheel B406 and auxiliary wheel B408. The passed mica ribbon 5 is connected to the drum outside the air shaft 6. During the winding process, the rotating rod 405 rotates outside the connecting seat 401. The torque of the torsion spring 4010 automatically adjusts the tension of the mica ribbon 5 during the winding process, preventing the mica ribbon 5 from being too tight or too loose, thus avoiding breakage due to excessive tightness or scattering due to excessive looseness. The tension adjustment speed of the mica ribbon 5 during winding is fast, and the structure is simple with low maintenance cost.

[0026] Example 2:

[0027] Please see Figure 1-3 This embodiment provides a technical solution for an automatic tension adjustment device for a mica belt on a tower tray, based on embodiment one: the reciprocating moving part 7 includes a servo motor 701 fixedly connected to the outside of the mounting rod 3, the output end of the servo motor 701 is fixedly connected to a reciprocating lead screw 702, and the reciprocating lead screw 702 is threadedly connected to the connecting seat 401.

[0028] A limit frame 8 is installed on the outer side of the guide wheel A403 and the guide wheel B406, and a limit rod 9 is symmetrically rotated inside the limit frame 8.

[0029] In this embodiment, when the mica ribbon 5 is wound to a certain thickness, the servo motor 701 drives the reciprocating screw 702 to rotate inside the mounting rod 3. The rotating reciprocating screw 702 drives the guide wheel A403 and guide wheel B406 on the outside of the connecting seat 401 to move, thereby changing the winding position of the mica ribbon 5. This process does not require stopping the equipment, realizing continuous winding of the mica ribbon 5 and speeding up the winding efficiency of the mica ribbon 5. The limiting frame 8 on the outside of the guide wheel A403 and guide wheel B406, and the limiting rod 9 symmetrically installed inside the limiting frame 8, limit the mica ribbon 5, preventing the mica ribbon 5 from becoming loose from the guide wheel A403 and guide wheel B406 during the winding process, thus affecting the normal winding of the mica ribbon 5.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle:

[0032] Before winding the mica tape 5, the torsion spring 4010 is inspected. If the torsion spring 4010 is damaged, it is replaced promptly to ensure the normal operation of the tension adjusting component 4. After inspecting the torsion spring 4010, the slit mica tape 5 is passed through the feed wheel 202 outside the crossbar 201, and one end of the mica tape 5 is pulled to wrap around the outside of the conveyor wheels A203, B204, and C205. Then, the mica tape 5 is passed between the guide wheel A403, auxiliary wheel A404, guide wheel B406, and auxiliary wheel B408, and one end of the mica tape 5 is connected to the outside of the drum outside the air shaft 6. During the winding process, the drive component inside the equipment box 1 drives the air shaft 6 to rotate, thereby winding the mica tape 5. During winding, the rotating rod 405 rotates inside the connecting seat 401, and the torque of the torsion spring 4010 is adjusted in a timely manner during the winding process of the mica tape 5. The tension of the mica ribbon 5 is adjusted to prevent it from breaking due to excessive tightness or becoming too loose and tangled. As the thickness of the wound mica ribbon 5 increases, the servo motor 701 drives the reciprocating screw 702 fixed at its output end to rotate inside the mounting rod 3 when adjusting the winding position of the mica ribbon 5. The rotating reciprocating screw 702 drives the connecting seat 401 connected to its outer side to slide on the outer side of the mounting rod 3. By adjusting the positions of the guide wheel A403 and guide wheel B406, the winding position of the mica ribbon 5 is offset. The winding of the mica ribbon 5 does not require stopping the equipment, thus improving the winding efficiency of the mica ribbon 5. During the winding process, the limiting frame 8 on the outer side of the guide wheel A403 and guide wheel B406, as well as the limiting rod 9 inside the limiting frame 8, limit the mica ribbon 5, preventing it from coming loose from the outer side of the guide wheel A403 or guide wheel B406 and preventing the operation of the equipment from being affected.
