Description

Technical Field

[0001] This utility model relates to the field of mica tape production technology, specifically to a mica tape winding device. Background Technology

[0002] Mica tape, a widely used insulating material in electrical equipment such as cables and motors, has its winding quality directly impacting subsequent processing efficiency and product reliability. Traditional winding devices mostly employ mechanical structures, relying on manual tension and alignment adjustments, which have significant limitations: firstly, mica tape is brittle and has poor ductility, making it prone to interlayer misalignment, edge wrinkling, and even breakage due to tension fluctuations during high-speed winding; secondly, the varying requirements for winding tightness and alignment accuracy of different specifications of mica tape cannot be met by fixed parameters, requiring time-consuming adjustments during frequent type changes. With the development of industrial automation, the shortcomings of existing equipment in intelligent detection, dynamic correction, and adaptive control are becoming increasingly apparent, necessitating the integration of key technologies such as high-precision sensors, closed-loop tension systems, and real-time correction mechanisms to achieve stable and flexible production in the winding process.

[0003] The utility model patent with application number CN202421127786.9 and publication number CN222204206U (hereinafter referred to as "Prior Art 1") discloses a winding device for producing mica tape with a blocking structure. It is applied in the field of mica tape production technology. This utility model uses a winding wheel to wind the mica tape, which gradually thickens the surface of the winding wheel. The thickening of the mica tape causes a square plate to move upward, which in turn drives a connecting rod to move upward. This causes a slider to slide on the surface of a guide post. This achieves the effect of blocking the end of the mica tape by the pressure of the square plate on the wound mica tape, thus preventing the end of the mica tape from loosening and falling off after winding.

[0004] The specification of prior art 1 discloses a winding device for producing mica tape with a blocking structure. In use, the mica tape is wound up by a winding wheel, which gradually thickens the surface of the winding wheel. However, in actual applications, the mica tape is small in width after being cut, and when it is wound onto a wider roller, uneven winding occurs, which in turn makes the winding effect of the mica tape worse. Summary of the Invention

[0005] This utility model provides a mica tape winding device, which aims to solve the problem that existing mica tape winding devices cannot adjust the winding position of the mica tape during the winding process, resulting in poor mica tape winding effect.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A mica tape winding device includes a support structure and an auxiliary winding structure. The support structure includes a support base and a mounting frame. The support base is mounted on the ground, and the mounting frame is hinged to the support base and used to rotatably mount a winding roller. The auxiliary winding structure includes a first drive assembly, a mounting block, a mounting plate, a limiting frame, and a limiting clamping plate. The first drive assembly is mounted on the mounting frame and is used to drive the mounting block to slide on the mounting frame. The mounting plate is mounted on the mounting block, and the limiting frame and limiting clamping plate are mounted on the mounting plate.

[0008] The support frame is equipped with a second drive assembly, which is used to drive the take-up roller to rotate on the mounting frame.

[0009] Furthermore, a telescopic structure is provided between the mounting frame and the support base. The movable end of the telescopic structure is hinged to the mounting frame, and the fixed end is hinged to the support base.

[0010] Furthermore, the first drive assembly includes a first motor, a ball screw, and a screw nut. The first motor is fixedly mounted on the mounting bracket, the ball screw is fixedly mounted on the output shaft of the first motor, and the screw nut is fixedly mounted on the mounting block. The screw nut and the ball screw cooperate with each other.

[0011] Furthermore, the mounting frame also has a guide assembly, which includes a guide rod and a bearing seat. The bearing seat is mounted on the mounting frame, the end of the ball screw is rotatably connected to the bearing seat, the two ends of the guide rod are fixedly connected to the two bearing seats respectively, and the mounting block is slidably connected to the guide rod.

[0012] Furthermore, the mounting frame is also equipped with an auxiliary disassembly structure, which is used to install the winding roller.

[0013] Furthermore, the auxiliary disassembly structure includes a rotating cylinder, a second drive assembly for driving the rotating cylinder to rotate, the rotating cylinder having a threaded hole, a screw being fitted inside the threaded hole, one end of the screw having a limiting block, the take-up roller having mounting recesses on both sides, the mounting recesses having limiting grooves, the screw being used to insert into the mounting recess so that the limiting block is used to insert into the limiting groove.

[0014] Furthermore, the second drive assembly includes a second motor and a transmission mechanism. The second motor is mounted on a support base and is used to control the rotation of the rotating cylinder through the transmission mechanism.

[0015] Furthermore, the limiting clamp includes a lower pad and an upper cover plate. The lower pad is disposed on the mounting plate, and the upper cover plate is hinged to the lower pad. Both the upper cover plate and the lower pad are provided with clearance grooves. The clearance grooves on the upper cover plate and the lower pad plate are engaged to form a limiting channel, which is used to limit the passage of mica tape.

[0016] Furthermore, the limiting frame includes a front mounting frame and a rear mounting frame, which are symmetrically arranged on the mounting plate. Both the front mounting frame and the rear mounting frame are equipped with pressure rollers and limiting posts. The two limiting posts are used to limit the horizontal position of the mica belt, and the pressure rollers are used to limit the vertical position of the mica belt.

[0017] Furthermore, a dust cover is provided on the support base, which is used to cover the transmission mechanism.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model mainly includes a support structure and an auxiliary winding structure. When winding the mica tape, the angle of the mounting frame needs to be adjusted first. Then, the mica tape is passed through the limiting frame and the limiting clamp and fixed to the edge of the winding roller. Then, the first drive component and the second drive component are started simultaneously. After the first drive component and the second drive component are started, the winding roller rotates to wind the mica tape. When the second drive component is started, the mounting block and the mica tape are also located at the edge of the winding roller. Then, the mounting block is driven to slide on the mounting frame. While the mounting block is sliding, it drives the mica tape to slide on the mounting frame, thereby adjusting the winding position of the mica tape so that the mica tape can be evenly wound on the winding roller. When the mounting block slides to the edge of the other end of the winding roller, the first drive component reverses and drives the mounting block to slide back to the initial position. This process is repeated to complete the winding of the mica tape. The advantage of this setting is that the mica tape can be evenly wound on the winding roller, resulting in a better winding effect.

Detailed Implementation

[0026] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0027] Please see Figures 1-4 As shown, this embodiment discloses a mica tape winding device, including a support structure and an auxiliary winding structure. The support structure includes a support base 101 and a mounting frame 102. The support base 101 is used to install on the ground, and the mounting frame 102 is hinged to the support base 101. A winding roller 103 is rotatably mounted on the mounting frame 102. The auxiliary winding structure includes a first drive assembly, a mounting block 104, a mounting plate 105, a limiting frame 106, and a limiting clamping plate 107. The first drive assembly is disposed on the mounting frame 102 and is used to drive the mounting block 104 to slide on the mounting frame 102. The mounting plate 105 is disposed on the mounting block 104, and the limiting frame 106 and the limiting clamping plate 107 are disposed on the mounting plate 105.

[0028] The support frame is equipped with a second drive assembly, which is used to drive the take-up roller 103 to rotate on the mounting frame 102.

[0029] This utility model mainly includes a support structure and an auxiliary winding structure. When winding the mica tape, the angle of the mounting frame 102 needs to be adjusted first. Then, the mica tape is passed through the limiting frame 106 and the limiting clamp 107 and fixed to the edge of the winding roller 103. Then, the first drive assembly and the second drive assembly are started simultaneously. After the first drive assembly and the second drive assembly are started, the winding roller 103 rotates to wind the mica tape. When the second drive assembly is started, the mounting block 104 and the mica tape are also located at the same position. The mica tape is wound around the edge of the take-up roller 103, and then the mounting block 104 is driven to slide on the mounting frame 102. As the mounting block 104 slides, it also drives the mica tape to slide on the mounting frame 102, thereby adjusting the winding position of the mica tape and ensuring it is evenly wound onto the take-up roller 103. When the mounting block 104 slides to the edge of the other end of the take-up roller 103, the first drive assembly reverses its direction and drives the mounting block 104 back to its initial position. This process is repeated to complete the winding of the mica tape. The advantage of this setup is that the mica tape can be evenly wound onto the take-up roller 103, resulting in a better winding effect.

[0030] In some embodiments, a telescopic structure 108 is provided between the mounting frame 102 and the support base 101. The movable end of the telescopic structure 108 is hinged to the mounting frame 102, and the fixed end is hinged to the support base 101.

[0031] In actual use, the purpose of setting the telescopic structure 108 is to facilitate the adjustment of the tilt angle of the mounting frame 102. As an optional implementation method, in this embodiment, the telescopic structure 108 is specifically a cylinder. The fixed end of the cylinder is hinged to the support frame, and the movable end of the cylinder is hinged to the mounting frame 102. When the cylinder extends, the mounting frame 102 tilts forward, and when the cylinder retracts, it drives the mounting frame 102 to tilt backward.

[0032] It should be noted that the cylinder in this embodiment is prior art. This embodiment does not involve any improvement to the cylinder structure or control method. The cylinder and control method in the prior art are used. Those skilled in the art should know how the cylinder is installed and used, so they will not be described in detail here.

[0033] In some embodiments, the first drive assembly includes a first motor 109, a ball screw 110, and a screw nut 111. The first motor 109 is fixedly mounted on the mounting bracket 102, the ball screw 110 is fixedly mounted on the output shaft of the first motor 109, and the screw nut 111 is fixedly mounted on the mounting block 104. The screw nut 111 and the ball screw 110 cooperate with each other.

[0034] In actual use, after the first motor 109 starts, it drives the ball screw 110 to rotate. Since the screw nut 111 and the ball screw 110 cooperate with each other, when the ball screw 110 rotates, it drives the screw nut 111 and the mounting bracket 102 to slide back and forth on the mounting bracket 102. When the first motor 109 rotates forward, the mounting block 104 moves away from the first motor 109. When the first motor 109 rotates in reverse, the mounting block 104 moves closer to the first motor 109.

[0035] In some embodiments, the mounting bracket 102 also has a guide assembly, which includes a guide rod 112 and a bearing seat 113. The bearing seat 113 is disposed on the mounting bracket 102, the end of the ball screw 110 is rotatably connected to the bearing seat 113, the two ends of the guide rod 112 are fixedly connected to the two bearing seats 113 respectively, and the mounting block 104 is slidably connected to the guide rod 112.

[0036] In actual use, the purpose of setting the guide component is to facilitate the limiting of the mounting block 104, so that the mounting block 104 can slide back and forth on the mounting frame 102.

[0037] In some embodiments, the mounting bracket 102 is further provided with an auxiliary disassembly structure, which is used to install the winding roller 103.

[0038] In actual use, the purpose of setting up the auxiliary disassembly structure is to facilitate the quick installation and disassembly of the winding roller 103.

[0039] In some embodiments, the auxiliary disassembly structure includes a rotating cylinder 114, a second driving assembly for driving the rotating cylinder 114 to rotate, the rotating cylinder 114 having a threaded hole, a screw 115 being fitted inside the threaded hole, one end of the screw 115 having a limiting block 116, mounting recesses 117 being provided on both sides of the winding roller 103, and limiting grooves 118 being provided on the mounting recesses 117, the screw 115 being used to insert into the mounting recesses 117 so that the limiting block 116 is used to insert into the limiting grooves 118.

[0040] In actual use, when the take-up roller 103 needs to be installed, the operator first needs to place the take-up roller 103 on the mounting bracket 102, aligning the mounting recesses 117 on both sides of the take-up roller 103 with the screws 115. Then, rotate the screws 115 on both sides of the mounting bracket 102 so that the limiting blocks 116 at the ends of the screws 115 engage with the limiting grooves 118, and the ends of the screws 115 are inserted into the mounting recesses 117. Finally, the take-up roller 103 is completed. When installing and disassembling the take-up roller 103, it is necessary to support the take-up roller 103, and then rotate the screw 115 on one side without the limiting block 116. After the screw 115 disengages from the mounting recess 117 on the same side, move the take-up roller 103, thereby disengaging the limiting block 116 on the other side from the limiting groove 118, and disengaging the screw 115 on the other side from the mounting recess 117 on the corresponding side, thus completing the disassembly of the take-up roller 103. The advantage of this design is that it facilitates the disassembly and installation of the take-up roller 103.

[0041] In some embodiments, the second drive assembly includes a second motor 119 and a transmission mechanism. The second motor 119 is mounted on the support base 101 and is used to control the rotation of the rotating cylinder 114 through the transmission mechanism.

[0042] As an optional implementation, in this embodiment, the mounting frame 102 is hinged to the support base 101 via a hinge shaft. The transmission mechanism includes a driving pulley, a first driven pulley, a second driven pulley, a third driven pulley, a first belt, and a second belt. The driving pulley is fixedly mounted on the output shaft of the second motor 119. The first and second driven pulleys are respectively fixedly mounted on both ends of the hinge shaft located on one side of the second motor 119. The third driven pulley is fixedly mounted on the rotating cylinder 114. The first belt is sleeved on the driving pulley and the first driven pulley, and the second belt is sleeved on the second driven pulley and the third driven pulley.

[0043] In actual use, when it is necessary to control the rotation of the rotating drum 114, the second motor 119 needs to be started. After the second motor 119 rotates, it drives the driving pulley to rotate. Under the action of the friction of the first belt, it drives the first driven pulley to rotate. Since the first driven pulley and the second driven pulley are fixedly connected to the hinge shaft, when the first driven pulley rotates, it drives the second driven pulley to rotate. After the second driven pulley rotates, under the action of the friction of the second belt, it drives the third driven pulley to rotate. After the third driven pulley rotates, it drives the rotating drum 114 to rotate. Under the limiting action of the limiting block 116 and the limiting groove 118, it drives the take-up roller 103 to rotate.

[0044] In some embodiments, the limiting clamp 107 includes a lower pad 120 and an upper cover 121. The lower pad 120 is disposed on the mounting plate 105, and the upper cover 121 is hinged to the lower pad 120. Both the upper cover 121 and the lower pad 120 are provided with clearance grooves. After the clearance grooves on the upper cover 121 and the lower pad 120 are engaged, a limiting channel 122 is formed. The limiting channel 122 is used to limit the passage of mica tape.

[0045] In actual use, the lower pad 120 and the upper cover 121 are hinged together. When the upper cover 121 is fastened to the lower pad 120, the mica tape can be limited.

[0046] In some embodiments, the limiting frame 106 includes a front mounting frame 123 and a rear mounting frame 124. The front mounting frame 123 and the rear mounting frame 124 are symmetrically arranged on the mounting plate 105. Both the front mounting frame 123 and the rear mounting frame 124 are provided with pressure rollers 125 and limiting posts 126. The two limiting posts 126 are used to limit the horizontal position of the mica strip, and the pressure rollers 125 are used to limit the vertical position of the mica strip.

[0047] In actual use, the pressure roller 125 can limit the longitudinal position of the mica strip, and the limiting post 126 can limit the lateral position of the mica strip, thereby enabling the mica strip to be wound more stably on the take-up roller 103.

[0048] In some embodiments, a dust cover 127 is provided on the support base 101, and the dust cover 127 is used to cover the transmission mechanism.

[0049] In actual use, the purpose of setting up the dust cover 127 is to prevent the transmission mechanism from being contaminated with dust and debris, so as to avoid affecting the transmission of the second motor 119.
