Technical Field

[0001] The present application relates to the field of cable production, and in particular to a mica wrapping device. Background Art

[0002] In the production process of special cables such as fire-resistant cables, control cables, and communication cables, special equipment such as mica tape wrapping machines are often used to achieve the purpose of wrapping and realize the effect of wrapping mica tape on the cable core.

[0003] In the related art, a reel wound with a cable core is unwound, the unwound core passes through a mica winding mechanism and is wrapped with a mica tape, and finally the wrapped core is reeled up by the reel, and then the reel is transported to the next work area.

[0004] However, the end of the wrapped wire core is not fixed on the wire wheel. After the wound wire wheel is transported, one end of the wire core is in a free state, which may easily cause the wire core to be accidentally unwound. Summary of the invention

[0005] In order to reduce the occurrence of accidental unwinding of the wire core during the transportation of the wound wire core, the present application provides a mica wrapping device.

[0006] The mica wrapping device provided in this application adopts the following technical solution:

[0007] A mica wrapping device comprises a support frame and a wire wheel detachably connected to the support frame and used for winding a wire core, a driving motor for driving the wire wheel to rotate is installed on the support frame, a locking mechanism for fixing the end of the wire core is detachably connected to the support frame, the locking mechanism comprises a connecting rod member detachably connected to the support frame and used for being fixedly connected to the wire wheel, and also comprises a clamping member, the clamping member comprises two mounting rods fixedly connected to the connecting rod member, a clamping block is provided between the two mounting rods, a pressure spring is fixedly connected between each mounting rod and a corresponding clamping block, the wire core passes through between the two clamping blocks and the two clamping blocks squeeze the wire core against each other.

[0008] By adopting the above technical solution, the wire core after mica wrapping passes through two clamping blocks and is wound on the reel, and the drive motor is started to drive the reel to rotate, and the reel rotates to reel the wire core. When the wire core is wrapped, the free end of the wire core that is not wound on the reel is clamped between the two clamping blocks, and then the connecting rod and the support frame are disassembled, and the connecting rod and the reel are fixed. At this time, the free end of the wire core is fixed by the clamping member, and the clamping member is fixed to the reel together with the connecting rod, which reduces the occurrence of accidental unwinding of the wire core during the transportation of the wound wire core.

[0009] Preferably, the sides of the two clamping blocks facing away from each other are each provided with a sliding groove, the sides of the two mounting rods facing each other are each fixedly connected with a sliding rod, and one end of each sliding rod is slidably plugged into a corresponding sliding groove.

[0010] By adopting the above technical solution, the two clamping blocks are pressed against each other by the force of the pressure spring, which is convenient for clamping wire cores of different diameters. During the expansion and contraction of the pressure spring, the sliding rod moves along the sliding groove, and the sliding rod and the sliding groove provide a guide for the expansion and contraction of the pressure spring.

[0011] Preferably, the connecting rod member includes a sleeve and two sleeve rods slidably connected to the sleeve, the two sleeve rods extend in directions away from each other and are fixedly connected with a limiting plate, two connecting holes are provided on the support frame, one end of each sleeve rod is plugged into a corresponding connecting hole, and a locking nut is threadedly connected to the end of the sleeve rod away from the sleeve, and the support frame is clamped between each locking nut and a corresponding limiting plate, two locking bolts are threadedly connected to the sleeve, and each locking bolt is tightly against a corresponding side wall of the sleeve rod, and the wire wheel includes two fixing plates, and each fixing plate is provided with a mounting hole for the sleeve rod to be plugged in.

[0012] By adopting the above technical solution, each locking nut is rotated until each locking nut is disengaged from the corresponding sleeve rod, and each locking bolt is rotated at the same time until each locking bolt is disengaged from the sleeve rod, and then the two sleeve rods are pushed toward each other, so that the length of the connecting rod is shortened. The connecting rod is placed between the two fixed plates of the reel, and then each sleeve rod is moved so that each sleeve rod is plugged into a corresponding mounting hole. Then, the locking nut is tightened at one end of each sleeve rod until the fixed plate is clamped between each locking nut and the corresponding limiting plate, and each locking bolt is rotated at the same time until each locking bolt presses the corresponding sleeve rod tightly, at which time the fixed connection between the connecting rod and the reel is completed, so that the locking mechanism for clamping the free end of the wire core can be transported together with the reel.

[0013] Preferably, an adjusting mechanism is provided above the locking mechanism, and the adjusting mechanism includes a receiving plate fixedly connected to the supporting frame, and an adjusting plate is installed on one side of the receiving plate, and two transmission members are installed on a side of the adjusting plate close to the locking mechanism, and each transmission member includes a roller shaft rotatably connected to the adjusting plate, one end of the roller shaft is coaxially fixed with a gear 1, one side of the gear 1 is meshed with a gear 2 rotatably connected to the adjusting plate, and one side of the gear 2 is meshed with a rack rod vertically slidably connected to the adjusting plate, each rack rod is fixedly connected to the adjusting plate, and a transmission spring is provided at the lower end of each rack rod, and the two inclined surfaces 1 are gradually inclined from top to bottom in a direction approaching each other, and each clamping block is provided with an inclined surface 2, and each inclined surface 1 is in contact with the corresponding inclined surface 2 box, and the wire core is clamped between the two roller shafts.

[0014] By adopting the above technical solution, the wire core passes through the two rollers. When the wire core is wound by the wire wheel, the wire core moves to drive the two rollers to rotate. The rotation of the roller drives the rack rod downward through gear 1 and gear 2. At this time, the inclined surface 1 on the rack rod pushes the inclined surface 2 on the clamping block, thereby driving the two clamping blocks to move away from each other. That is, during the movement of the wire core, the two clamping blocks are separated from the contact wire core, reducing the damage to the wire core. When the wire core is about to be wound up, the wire core is separated from the two rollers. At this time, the rack rod is reset upward by the force of the transmission spring, and the two clamping blocks are clamped by the force of the pressure spring. The effect of the two clamping blocks instantly clamping the free end of the wire core when the wire core is separated from the two rollers is achieved.

[0015] Preferably, the rack rod includes a rack segment meshing with the second gear, and also includes a smooth segment located above the rack segment.

[0016] By adopting the above technical solution, when gear 2 drives the rack segment to move downward until gear 2 is separated from the rack segment and approaches the smooth segment, the rack rod stops moving downward.

[0017] Preferably, the roller is made of elastic material.

[0018] By adopting the above technical solution, the roller can better clamp the wire core, that is, during the movement of the wire core, the wire core can drive the roller to rotate more smoothly.

[0019] Preferably, the regulating plate comprises two adjusting plates, two regulating blocks are fixedly connected to one side of the supporting plate, a guide column is fixedly connected between the two regulating blocks, each regulating block is slidably connected to the guide column, a bidirectional lead screw is rotatably connected between the two regulating blocks, and the two regulating blocks are separated at each end of the bidirectional lead screw and are threadedly connected to the bidirectional lead screw.

[0020] By adopting the above technical solution, the bidirectional screw is rotated, and the rotation of the bidirectional screw drives the two regulating blocks to move along the guide column in the direction of approaching or moving away from each other. The movement of the two regulating blocks drives the two roller shafts to move in the direction of approaching or moving away from each other, so that the two roller shafts can clamp the wire cores of different diameters.

[0021] Preferably, each of the fixing plates is provided with a circle of mounting holes.

[0022] By adopting the above technical solution, it is convenient to select a more suitable installation hole for installing the connecting rod, so that when the connecting rod is installed on the wire wheel, the wire core can better maintain a tensioned state and reduce the occurrence of relaxation.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The free end of the wire core is fixed by the clamping member, and the clamping member is fixed to the wire wheel together with the connecting rod member, which reduces the occurrence of accidental unwinding of the wire core during the transportation of the wound wire core;

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0032] The present application embodiment discloses a mica wrapping device. Figure 1 and Figure 2 The mica wrapping device comprises an unwinding part, a winding part and a winding part, wherein the winding part is provided with a support frame 1, and a wire wheel 2 is detachably connected to the support frame 1. A locking mechanism 3 for fixing the end of the wire core is installed on the support frame 1.

[0033] The support frame 1 includes a support plate 11 and two support rods 12 fixedly connected to the upper surface of the support plate 11, and the two support rods 12 are used to install the wire wheel 2. The wire wheel 2 includes two fixed plates 21 and a wire shaft 22 fixedly connected between the two fixed plates 21, wherein a rectangular groove 211 is provided on the side of one of the fixed plates 21 facing away from the wire wheel 2, and a circular groove 212 is provided on the side of the other fixed plate 21 facing away from the wire wheel 2. A fixed shaft 13 is rotatably connected to one of the support rods 12, and a fixed shaft 2 14 is fixedly connected to the other support rod 12 by bolts and nuts, and the fixed shaft 13 and the fixed shaft 2 14 both pass through the corresponding support rods 12 horizontally.

[0034] The vertical cross section of the fixed shaft 13 is rectangular, and one end of the fixed shaft 13 is plugged into the rectangular groove 211. The vertical cross section of the fixed shaft 2 14 is circular, and one end of the fixed shaft 2 14 is plugged into the circular groove 212. The support rod 12 connected to the fixed shaft 13 is fixedly connected to the driving motor 15, and the output shaft of the driving motor 15 is coaxially fixed with the fixed shaft 13.

[0035] One end of the wire core is fixed and wound on the bobbin 22, and then the wire core is wrapped with mica, and the drive motor 15 is started at the same time. The output shaft of the drive motor 15 drives the fixed shaft 13 and the wire wheel 2 to rotate, so that the wrapped wire core is wound. When the winding is completed, the lock between the fixed shaft 2 14 and the corresponding support rod 12 is released by turning the bolt nut, and then the fixed shaft 2 14 is moved away from the wire wheel 2, and then the wire wheel 2 is moved away from the fixed shaft 13, so that the wire wheel 2 can be disassembled.

[0036] Reference Figure 1 and Figure 3 The locking mechanism 3 includes a connecting rod 31 detachably connected between the two supporting rods 12, and a clamping member 32 is fixedly connected to the connecting rod 31. The clamping member 32 includes two mounting rods 321 fixedly connected to the connecting rod 31, and two clamping blocks 322 are arranged between the two mounting rods 321. The two clamping blocks 322 are provided with sliding grooves 3221 on the side opposite to each other, and the two mounting rods 321 are fixedly connected with sliding rods 323 on the side close to each other, one sliding rod 323 corresponds to one sliding groove 3221, and one end of the sliding rod 323 is slidably plugged into the sliding groove 3221.

[0037] A pressure spring 324 is sleeved on the outer side of each slide bar 323, one end of each pressure spring 324 is fixedly connected to a corresponding clamping block 322, and the other end is fixedly connected to a corresponding mounting rod 321. The two clamping blocks 322 are pressed against each other on their adjacent sides, and each pressure spring 324 is in a compressed state.

[0038] During the working process, the wire core passes between the two clamping blocks 322 and is then wound on the wire wheel 2. During the working process, the wire core always passes between the two clamping blocks 322. After the wire core is wrapped, the free end of the wire core is clamped on the clamping member 32. Then, the connecting rod 31 and the support frame 1 are disassembled, and the connecting rod 31 and the wire wheel 2 are fixed, so that it is not easy to unwind during the process of moving the wire wheel 2. After the connecting rod 31 is fixedly connected to the wire wheel 2, it is convenient to hoist and move the wire wheel 2 with the help of the connecting rod 31.

[0039] Reference Figure 1 and Figure 2 The connecting rod 31 includes a sleeve 311 and two sleeve rods 312 slidably plugged with the sleeve 311. The ends of the two sleeve rods 312 that are away from each other extend out of the sleeve 311 and are fixedly connected with a limiting plate 313. A connecting hole 121 that passes through the support rod 12 horizontally is opened at the upper end of each support rod 12. Each sleeve rod 312 is plugged into a corresponding connecting hole 121. A locking nut 314 is threadedly connected to the end of each sleeve rod 312 away from the sleeve 311. Each locking nut and the corresponding limiting plate 313 clamp one of the support rods 12. Two locking bolts 315 are threadedly connected to both ends of the sleeve 311. One locking bolt 315 corresponds to one sleeve rod 312. One end of the locking bolt 315 extends out of the sleeve 311 and presses against the side wall of the corresponding sleeve rod 312.

[0040] Each fixing plate 21 is provided with a plurality of mounting holes 213 , and the plurality of mounting holes 213 are evenly distributed around the axis of the fixing plate 21 .

[0041] Rotate each locking nut 314 until each locking nut 314 is disengaged from the corresponding sleeve rod 312. At the same time, rotate each locking bolt 315 until each locking bolt 315 is disengaged from the corresponding sleeve rod 312. Push the two sleeve rods 312 in a direction toward each other until each sleeve rod 312 is disengaged from the corresponding support rod 12. Then place the connecting rod 31 between the two fixing plates 21, and move the two sleeve rods 312 in a direction away from each other until one end of each sleeve rod 312 is plugged into a corresponding mounting hole 213, while ensuring that the limiting plate 313 contacts the inner wall of the corresponding fixing plate 21.

[0042] Then, each locking bolt 315 is rotated until each locking bolt 315 is pressed against the corresponding sleeve rod 312, and each locking nut 314 is threadedly connected to the corresponding sleeve rod 312, so that the corresponding fixing plate 21 is clamped between each locking nut 314 and the corresponding limiting plate 313. At this time, the wire wheel 2 can be moved by the connecting rod 31. It should be noted that after the connecting rod 31 is connected to the corresponding two mounting holes 213, the wire core is kept in a tensioned state as much as possible.

[0043] Reference Figure 1 and Figure 3 However, when the wire core is wound, if the two clamping blocks 322 always clamp the moving wire core, it is easy to cause wear to the wire core. In order to solve this problem, a regulating mechanism 4 is provided on one side of the clamping member 32.

[0044] The regulating mechanism 4 includes a receiving plate 41 fixedly connected to the upper surface of the support plate 11, and the receiving plate 41 is vertically arranged upward. A regulating plate 42 is installed on one side of the receiving plate 41 close to the locking mechanism 3, and two transmission members 43 are installed on one side of the regulating plate 42 close to the locking mechanism 3.

[0045] Each transmission member 43 includes a roller shaft 431, a gear 1 432, a gear 2 433, a rack rod 434 and a fixed block 435. One end of the roller shaft 431 is coaxially connected to the gear 1 432, and the gear 1 432 is connected to the regulating plate 42. The wire core passes through the two roller shafts 431 and the two roller shafts 431 clamp the wire core. One side of each gear 1 432 is meshed with the corresponding gear 2 433, and each rack rod 434 is meshed with the corresponding gear 2 433. Each rack rod 434 is vertically arranged downward, and the rack rod 434 is vertically connected to the regulating plate 42 in a sliding manner.

[0046] Each fixing block 435 is fixedly connected to the regulating plate 42, and the fixing block 435 is located above the rack rod 434. A transmission spring 436 is provided between each fixing block 435 and the corresponding rack rod 434, and one end of the transmission spring 436 is fixedly connected to the fixing block 435, and the other end is fixedly connected to the rack rod 434. The rack rod 434 includes a rack section 4341 and a smooth section 4342, and the smooth section 4342 is located above the rack section 4341, and the rack section 4341 is meshed with the second gear 433.

[0047] One transmission member 43 corresponds to one clamping block 322, and the lower end of each rack rod 434 is provided with an inclined surface 1 4343, and the two inclined surfaces 1 4343 are gradually inclined from top to bottom in a direction of approaching each other. The upper end of each clamping block 322 is provided with an inclined surface 2 3222, and the two inclined surfaces 2 3222 are inclined from top to bottom in a direction of approaching each other. One inclined surface 1 4343 corresponds to one inclined surface 2 3222, and the inclined surface 1 4343 and the inclined surface 2 3222 are in contact with each other.

[0048] When the wire core is wound up, the wire core moves downward between the two rollers 431, and the two rollers 431 rotate under the drive of the wire core. The rotation of the roller 431 drives the gear 1 432 and the gear 2 433 to rotate, and the rotation of each gear 2 433 drives each rack rod 434 to move downward. At this time, the inclined surface 1 4343 gradually applies a force to the inclined surface 2 3222, thereby driving the two clamping blocks 322 to move away from each other. When the rack rod 434 moves downward until the rack segment 4341 is separated from the gear 2 433, the rack rod 434 stops moving downward. At this time, the clamping block 322 is separated from the clamping of the wire core, and the wire core moves relatively smoothly. The gear 2 433 continues to rotate, limiting the upward movement of the rack rod 434.

[0049] When the wire core is wrapped, the free end of the wire core gradually passes through and disengages from between the two rollers 431, and then the rollers 431 stop rotating, and the rack rod 434 moves upward and resets under the action of the transmission spring 436, and the two clamping rods clamp the free end of the wire core under the action of the pressure spring 324, and at the same time, the drive motor 15 is turned off to stop the rotation of the wire wheel 2.

[0050] In order to facilitate the wire cores of different diameters to pass through between the two rollers 431 and drive the rollers 431 to rotate more smoothly, the regulating plate 42 includes two adjusting plates 421 , one transmission member 43 corresponds to one adjusting plate 421 and the transmission member 43 is installed on the adjusting plate 421 .

[0051] Two regulating blocks 422 are fixedly connected to one side of the receiving plate 41 close to the locking mechanism 3, a guide column 423 is fixedly connected between the two regulating blocks 422, and a bidirectional lead screw 424 is rotatably connected between the two regulating blocks 422, and one end of the bidirectional lead screw 424 is fixedly connected to a hand wheel (not shown in the figure).

[0052] The guide column 423 passes through the two adjustment plates 421 and is slidably connected to the adjustment plates 421 . The bidirectional lead screw 424 passes through the two adjustment plates 421 and is threadedly connected to each adjustment plate 421 .

[0053] The hand wheel is turned to drive the bidirectional lead screw 424 to rotate, and the bidirectional lead screw 424 rotates to drive the two adjustment plates 421 to move toward or away from each other, so that the distance between the two rollers 431 can be adjusted to facilitate the passage of wire cores of different diameters.

[0054] The implementation principle of a mica wrapping device in an embodiment of the present application is as follows: after the wire core is wrapped, it passes through two rollers 431 and two clamping blocks 322 in sequence and then is wound around the wire wheel 2. During the process of the wire wheel 2 rotating and winding, the wire wheel 2 rotates relative to the two rollers 431. The rotation of the two rollers 431 drives the inclined surface 1 4343 on the rack rod 434 to push the inclined surface 2 3222, thereby pushing the two clamping blocks 322 to move away from each other. At this time, the clamping blocks 322 are separated from the clamping wire core.

[0055] When the wire core is wrapped, the free end of the wire core passes through the two rollers 431 and detaches from the two rollers 431. At this time, the rack rod 434 is reset by the force of the transmission spring 436, and the two clamping blocks 322 move toward each other under the force of the corresponding pressure springs 324 and clamp the free end of the wire core, thereby fixing the free end of the wire core.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
