Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, specifically a winding device for processing flame-retardant cables. Background Technology

[0002] With the continuous advancement of global infrastructure construction in areas such as power, communications, and transportation, the market demand for cables, as key carriers of energy and information transmission, continues to grow. Flame-retardant cables, as an important branch of the cable industry, are widely used in places with extremely high fire safety requirements, such as buildings, subways, airports, and data centers. After production is completed, the winding process is a particularly important step.

[0003] A search revealed a utility model patent with Chinese patent publication number CN216686903U, which discloses a winding device for cable production and processing, comprising a base plate, a tensioning mechanism, and a conductor mechanism; the base plate has a support frame fixedly connected to its upper surface, a transmission roller rotatably connected to the upper end of the support frame, a winding roller movably sleeved on the outer side of the transmission roller, and support columns symmetrically fixedly connected to the front side of the upper surface of the base plate, with the upper ends of the support columns all fixedly connected to the support plate; the tensioning mechanism is located inside the transmission roller and is installed in conjunction with the winding roller.

[0004] The above-mentioned device supports the winding drum through a drive roller. When the cable is fully wound, the weight is too great, so the process of removing the drive roller is inconvenient and takes a long time, which is not conducive to improving work efficiency and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a winding device for processing flame-retardant cables, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a winding device for processing flame-retardant cables, comprising a support frame and a mounting frame, wherein the mounting frame is disposed at the top of the support frame, and a common shifting component is installed between the support frame and the mounting frame. The shifting component includes two extension plates fixedly connected to both sides of the outer wall of the top of the support frame, and a common lead screw is rotatably connected between the two extension plates. A motor is fixedly installed on one side of the outer wall of one of the extension plates, and the output end of the motor is coaxially fixed with one end of the lead screw. Two guide rails are fixedly connected to one end of the outer wall of the top of the support frame, and the mounting frame is slidably connected to the outside of the two guide rails. The lead screw is threadedly connected inside the mounting frame.

[0007] The system can promptly transfer a fully wound take-up drum to one side and allow a new take-up drum to replace it, facilitating continuous winding and improving work efficiency. Once the cable is fully wound, an external motor on an extension plate is activated. The motor drives a lead screw to rotate, which in turn moves the mounting frame along two guide rails to one side. The take-up drum at the top of the mounting frame will move to the side of the support frame, while the empty take-up drum will move to the top of the support frame. Simply secure the cable inside the new take-up drum to continue winding. The completed take-up drum can be removed and replaced during the winding process.

[0008] As a further preferred embodiment of this technical solution, each of the four corners of the bottom outer wall of the mounting frame is fixedly connected to a support column, and each of the four support columns is rotatably connected to a roller, with the four rollers being at the same level as the bottom wall of the support frame.

[0009] As a further preferred embodiment of this technical solution, a transmission assembly is installed on the top of the mounting frame. The transmission assembly includes a mounting base fixedly connected to the outer wall of the top of the mounting frame. Two symmetrically arranged motors are installed inside the mounting base. Two movable seats are slidably sleeved in the middle of the mounting frame. A drive disk is rotatably connected to the side of the two movable seats that are close to each other and to the outer walls of both sides of the mounting base. The two motors are coaxially fixed to the two middle drive disks respectively. Several equally spaced drive columns are provided on the outside of the four drive disks.

[0010] As a further preferred embodiment of this technical solution, the mounting bracket has several equally spaced insertion holes inside, and a limiting pin is slidably inserted between each of the two movable seats and the mounting bracket, with the two limiting pins respectively slidably inserted into the four corresponding insertion holes on the mounting bracket.

[0011] As a further preferred embodiment of this technical solution, a common take-up drum is installed between the two drive discs that are close to each other, and the take-up drum is provided with a plug hole that is adapted to the drive column of the drive disc.

[0012] As a further preferred embodiment of this technical solution, a support assembly is installed on the top of the mounting frame. The support assembly includes two limiting grooves opened inside the mounting frame. A bidirectional lead screw is rotatably connected inside each of the two limiting grooves. A support seat is threaded to the threaded ends of each of the two bidirectional lead screws. A receiving roller is rotatably connected inside each of the four support seats.

[0013] As a further preferred embodiment of this technical solution, a horizontally arranged transmission rod is rotatably connected inside the mounting frame. Two bevel gears are coaxially fixed to the outside of the transmission rod. A bevel gear is coaxially fixed to the same end of each of the two bidirectional lead screws. The two bevel gears mesh with the two bevel gears respectively. A motor is installed outside the mounting frame. The output end of the motor is coaxially fixed to one end of the transmission rod.

[0014] If the size of the take-up drum becomes smaller, the second motor outside the mounting frame can be started. The second motor drives the transmission rod to rotate, and the two bevel gears outside the transmission rod will also rotate synchronously. The two bevel gears mesh to drive the two bevel gears to rotate synchronously. The two bevel gears drive the two bidirectional lead screws to rotate synchronously, and thus the four support seats will be driven to move closer to each other. The receiving rollers inside the two support seats support the take-up drum, so that it maintains a certain height after being fully wound, thus preventing damage to the drive disc.

[0015] As a further preferred embodiment of this technical solution, the thread helix angle of the bidirectional lead screw and the external thread of the lead screw is less than the equivalent friction angle.

[0016] This utility model provides a winding device for processing flame-retardant cables, which has the following advantages: (1) By setting up a switching component, this utility model can promptly transfer the winding drum to one side after it is fully wound, and can replace the original position with a new winding drum, so as to facilitate the continuous winding work and improve work efficiency. After the cable is fully wound, start an external motor of an extension plate. The motor drives the lead screw to rotate, and the lead screw drives the mounting frame to move to one side along the two guide rails. The winding drum at the top of the mounting frame will move to the side of the support frame, while the empty winding drum will move to the top position of the support frame. As long as the cable is fixed inside the new winding drum, the winding can continue. The winding drum that has been wound can be taken out and replaced during the winding work.

[0017] (2) By setting up a support assembly, if the size of the winding drum becomes smaller, the second motor outside the mounting frame can be started. The second motor drives the transmission rod to rotate, and the two bevel gears outside the transmission rod will also rotate synchronously. The two bevel gears will mesh to drive the two bevel gears to rotate synchronously. The two bevel gears will drive the two bidirectional screws to rotate synchronously, and then the four support seats will be driven to move closer to each other. The receiving roller inside the two support seats supports the winding drum, so that it maintains a certain height after winding is full, so as not to crush the drive disc.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown in this embodiment, a winding device for processing flame-retardant cables includes a support frame 1 and a mounting frame 2. The mounting frame 2 is located at the top of the support frame 1. A common switching component 4 is installed between the support frame 1 and the mounting frame 2. The switching component 4 includes two extension plates 401 fixedly connected to both sides of the top outer wall of the support frame 1. A common lead screw 402 is rotatably connected between the two extension plates 401. A motor 404 is fixedly installed on one side outer wall of one extension plate 401. The output end of the motor 404 is coaxially fixed with one end of the lead screw 402. Two guide rails 403 are fixedly connected to one end of the top outer wall of the support frame 1. The mounting frame 2 is slidably connected to the outside of the two guide rails 403. The lead screw 402 is threadedly connected inside the mounting frame 2.

[0021] Each of the four corners of the bottom outer wall of the mounting bracket 2 is fixedly connected to a support column 405. Each of the four support columns 405 is rotatably connected to a roller 406. The four rollers 406 are all at the same level as the bottom wall of the support frame 1, which can support the part of the mounting bracket 2 that extends to one side of the support frame 1, which helps to improve the stability of the support frame 1.

[0022] After the cable is fully wound, an external motor 404 of an extension plate 401 is activated. The motor 404 drives the lead screw 402 to rotate, which in turn drives the mounting frame 2 to move to one side along the two guide rails 403. The winding drum 3 at the top of the mounting frame 2 will move to one side of the support frame 1, while the empty winding drum 3 will move to the top of the support frame 1. The cable can be fixed inside the new winding drum 3 to continue winding. The winding drum 3 can be removed and replaced during the winding process.

[0023] like Figure 2 and Figure 3 As shown, a transmission assembly 6 is installed on the top of the mounting frame 2. The transmission assembly 6 includes a mounting base 601 fixedly connected to the outer wall of the top of the mounting frame 2. Two symmetrically arranged motors are installed inside the mounting base 601. Two movable seats 602 are slidably sleeved in the middle of the mounting frame 2. A drive disk 603 is rotatably connected to the side of the two movable seats 602 that are close to each other and to the outer walls of both sides of the mounting base 601. The two motors are coaxially fixed to the two middle drive disks 603 respectively. Several drive columns are evenly distributed on the outside of the four drive disks 603.

[0024] The mounting bracket 2 has several equally spaced insertion holes 604 inside. Each of the two movable seats 602 and the mounting bracket 2 is slidably connected to a limiting pin 605. The two limiting pins 605 are respectively slidably inserted into the four corresponding insertion holes 604 on the mounting bracket 2.

[0025] A take-up drum 3 is installed between two drive discs 603 that are close to each other. The inside of the take-up drum 3 is provided with a plug hole that is adapted to the drive column of the drive disc 603. Different specifications of take-up drums 3 are provided with through holes that are adapted to the plug rod of the drive disc 603, so that the drive disc 603 can accommodate the installation of take-up drums 3 of different specifications.

[0026] The disassembly process is as follows: pull the limit pin 605 out of the inside of the movable seat 602 and the mounting bracket 2. At this time, the movable seat 602 will no longer be restricted and can be removed directly. When disassembling the movable seat 602, the receiving roller provided inside the support seat 503 can ensure that the winding drum 3 will not tilt due to loss of support. In addition, since there are several insertion holes 604, it can be ensured that the movable seat 602 can adapt to the driving operation of winding drums 3 of different specifications.

[0027] like Figure 3 and Figure 4 As shown, a support assembly 5 is installed on the top of the mounting frame 2. The support assembly 5 includes two limiting grooves 501 opened inside the mounting frame 2. A bidirectional lead screw 502 is rotatably connected inside each of the two limiting grooves 501. A support seat 503 is threadedly connected to the threaded ends of each of the two bidirectional lead screws 502. A receiving roller is rotatably connected inside each of the four support seats 503.

[0028] The mounting bracket 2 is internally connected to a horizontally arranged transmission rod 504. Two bevel gears 506 are coaxially fixed to the outside of the transmission rod 504. Two double-acting lead screws 502 are each coaxially fixed to a bevel gear 505 at the same end. The two bevel gears 505 mesh with the two bevel gears 506 respectively. A motor 507 is mounted on the outside of the mounting bracket 2. The output end of the motor 507 is coaxially fixed to one end of the transmission rod 504.

[0029] If the size of the take-up drum 3 becomes smaller, the motor 507 outside the mounting bracket 2 can be started. The motor 507 drives the transmission rod 504 to rotate, and the two bevel gears 506 outside the transmission rod 504 will also rotate synchronously. The two bevel gears 506 mesh with each other to drive the two bevel gears 505 to rotate synchronously. The two bevel gears 505 drive the two bidirectional lead screws 502 to rotate synchronously. As a result, the four support seats 503 will be driven to move closer to each other, and the receiving rollers inside the two support seats 503 support the take-up drum 3 to maintain a certain height after it is fully wound, so as not to crush the drive disc 603.

[0030] like Figure 3 and Figure 4 As shown, the thread helix angle of the external threads of the two-way lead screw 502 and lead screw 402 is less than the equivalent friction angle, which makes both of them have self-locking properties, thereby ensuring that the position of the structure connected to them will not be arbitrarily changed by external forces.

[0031] This utility model provides a winding device for processing flame-retardant cables, the specific working principle of which is as follows: When the device is working, the cable guide device is installed on the top of the support frame 1, opposite the mounting frame 2. After the cable passes through the guide ring of the guide device, it is fixed inside a winding drum 3. A driver inside the mounting base 601 is activated, which drives the drive disk 603 connected to it to rotate. With the cooperation of the drive disk 603 installed inside the moving base 602, the winding drum 3 can wind up the cable. After the cable is fully wound, an external motor 404 of an extension plate 401 is activated. The motor 404 drives the lead screw 402 to rotate, which in turn drives the mounting frame 2 to move to one side along the two guide rails 403. The winding drum 3 at the top of the mounting frame 2 will move to one side of the support frame 1, while the empty winding drum 3 will move to the top position of the support frame 1. As long as the cable is fixed inside the new winding drum 3, winding can continue. The winding drum 3 can be removed and replaced during the winding process.

[0032] The disassembly process is as follows: pull the limit pin 605 out of the inside of the movable seat 602 and the mounting bracket 2. At this time, the movable seat 602 will no longer be restricted and can be removed directly. When disassembling the movable seat 602, the receiving roller provided inside the support seat 503 can ensure that the winding drum 3 will not tilt due to loss of support. In addition, since there are several insertion holes 604, it can be ensured that the movable seat 602 can adapt to the driving operation of winding drums 3 of different specifications.

[0033] If the size of the take-up drum 3 becomes smaller, the motor 507 outside the mounting bracket 2 can be started. The motor 507 drives the transmission rod 504 to rotate, and the two bevel gears 506 outside the transmission rod 504 will also rotate synchronously. The two bevel gears 506 mesh with each other to drive the two bevel gears 505 to rotate synchronously. The two bevel gears 505 drive the two bidirectional lead screws 502 to rotate synchronously. As a result, the four support seats 503 will be driven to move closer to each other, and the receiving rollers inside the two support seats 503 support the take-up drum 3 to maintain a certain height after it is fully wound, so as not to crush the drive disc 603.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
