Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, and particularly relates to a winding device for processing low-smoke and halogen-free polyolefin fire-resistant cables. Background Technique

[0002] The low-smoke and halogen-free polyolefin fire-resistant cable is a cable product with excellent performance and is widely used in modern buildings, transportation, energy and other fields. When the low-smoke and halogen-free polyolefin fire-resistant cable burns, the amount of smoke generated is extremely low, and the released gas does not contain harmful substances such as halogens, such as chlorine, hydrogen halide, etc., thus greatly reducing the harm to the environment and the human body. This cable has excellent flame retardant performance, can effectively slow down the spread speed of the flame during a fire, gain more time for fire fighting, and still maintain a certain operating time under the condition of flame combustion, ensuring the normal operation of key equipment during a fire and providing strong support for personnel evacuation and fire fighting work. The winding device for processing is a crucial device in the cable production process. It is mainly used to wind the produced low-smoke and halogen-free polyolefin fire-resistant cables orderly and efficiently for subsequent packaging, transportation and use.

[0003] For this reason, Chinese Patent Application No. CN208103557U discloses a winding device for electric wires and cables, including: a rotating shaft main body, chuck plates are arranged at both ends of the rotating shaft main body, the chuck plates are used to limit the movement of the spool sleeved on the rotating shaft main body in the length direction of the rotating shaft main body, and the rotating shaft main body is composed of a first rotating shaft and a second rotating shaft, and the first rotating shaft and the second rotating shaft are detachably connected; a power device, connected to the rotating shaft main body, for driving the rotating shaft main body. When the spool is fixed on the winding device through the detachably connected first rotating shaft and second rotating shaft and the chuck plates arranged at both ends thereof, the motor drives the rotation of the rotating shaft main body to drive the rotation of the spool to achieve the winding operation; the detachably connected first rotating shaft and second rotating shaft make the installation of the spool more convenient and fast.

[0004] The current winding devices can basically meet people's usage requirements, but there are still some problems, which are specifically described as follows:

[0005] 1. The problem that the winding device is difficult to guide the winding direction of the cable. When winding the cable, it is necessary to ensure that the cable is neat and orderly to avoid mutual cross-winding. The randomly wound cable will be deformed and cracked due to lateral force, directly affecting the service performance and life of the cable.

[0006] 2. Problem that the take-up device is difficult to quickly replace the take-up rod. After the cable take-up is completed, all the cables together with the take-up rod need to be removed from the take-up device. At this time, due to the heavy overall weight, the complex disassembly process will prolong the time for replacing the take-up rod and reduce the overall working efficiency. Utility Model Content

[0007] The purpose of the present utility model is to provide a take-up device for processing low-smoke, halogen-free polyolefin fire-resistant cables, so as to solve the defects that the existing take-up device is difficult to guide the take-up direction of the cables and is difficult to quickly replace the take-up rod.

[0008] To solve the above technical problems, the present utility model provides the following technical solution: A take-up device for processing low-smoke, halogen-free polyolefin fire-resistant cables, including a support frame;

[0009] A lifting structure is welded to the top end of the support frame, and a guiding mechanism is installed inside the lifting structure;

[0010] The guiding mechanism includes a sliding transverse groove, a first servo motor, a transverse threaded rod, a sliding frame and a guiding wheel. The sliding transverse groove is clamped inside the lifting structure. A first servo motor is fixedly installed on one side inside the sliding transverse groove. The transverse threaded rod penetrates through the inside of the sliding transverse groove. A sliding frame is movably installed on the outer side of the transverse threaded rod. A guiding wheel is rotatably connected to the inside of the sliding frame;

[0011] A second servo motor is fixedly installed on one side of the support frame. A rotating shaft is fixedly installed at the output end of the second servo motor. A conveyor belt is arranged on the outer side of the rotating shaft. A fixing structure is installed on one side of the support frame. A take-up rod is clamped on one side of the fixing structure.

[0012] During use, first start the hydraulic rod to move the second fixing block away from the first fixing block, align the card slot on the take-up rod with the card blocks on the first fixing block and the second fixing block and snap them in, start the hydraulic rod to fix the take-up rod, then pass the cable to be taken up through between the two guiding wheels and fix it on the take-up rod, start the first servo motor and the second servo motor. The second servo motor will drive the rotation of the take-up rod to take up the cable. The first servo motor drives the transverse threaded rod to rotate, thereby driving the sliding frame to move back and forth in the sliding transverse groove, thereby guiding the take-up direction of the cable. Finally, when it is necessary to adjust the take-up tightness of the cable, it is necessary to rotate the turntable to drive the longitudinal threaded rod to rotate, so that the guiding wheel moves up and down along with the sliding transverse groove, thereby adjusting the tension of the take-up.

[0013] Further, the lifting structure includes a first support rod, a second support rod, a longitudinal threaded rod and a turntable. The first support rod is welded to one side of the top of the support frame, and the second support rod is welded to the other side of the top of the support frame. The longitudinal threaded rod passes through the inside of the second support rod, and the turntable is welded to the top of the longitudinal threaded rod. By changing the cable winding direction, the winding tightness is changed.

[0014] Further, a slider is arranged inside the first support rod, and sliding grooves are arranged at both ends of one side of the sliding transverse groove. The sliding transverse groove is slidably connected to the first support rod, enabling the sliding transverse groove to stably lift inside the first support rod and the second support rod.

[0015] Further, external threads are uniformly arranged on the outer side wall of the transverse threaded rod, and internal threads that cooperate with the external threads are uniformly arranged on the inner side wall of the sliding frame. The transverse threaded rod is threadedly connected to the sliding frame. By rotating the transverse threaded rod inside the sliding transverse groove, the sliding frame is driven to move left and right in the sliding transverse groove.

[0016] Further, the fixing structure includes a first fixing block, a second fixing block, a hydraulic rod and a clamping block. The first fixing block is fixedly installed on one side of the rotating shaft, the second fixing block is clamped on one side of the winding rod, and a hydraulic rod is rotatably connected to one side of the second fixing block. The rapid disassembly and assembly of the winding rod are realized through the telescoping of the hydraulic rod.

[0017] Further, clamping blocks are integrally formed on one side of the first fixing block and the second fixing block, and the clamping blocks are annularly distributed, ensuring that the winding rod rotates together when the second servo motor drives the first fixing block to rotate.

[0018] Further, baffles are fixedly installed at both ends of the outer side of the winding rod, and the baffles are symmetrically distributed about the central axis of the winding rod, preventing the cable from slipping and crossing when the number of winding layers is too large.

[0019] The winding device for processing low-smoke, halogen-free polyolefin fire-resistant cables provided by the present utility model has the following advantages: By installing a sliding transverse groove in the middle of the first support frame and the second support frame, the first servo motor fixed on one side of the sliding transverse groove can drive the transverse threaded rod inside the sliding transverse groove to rotate, thereby driving the sliding frame to move left and right in the sliding transverse groove. The cable to be wound needs to pass through between two guide wheels first. The guide wheels can rotate to ensure the smoothness of cable winding. The first servo motor rotates forward first to move the sliding frame to one side, and then rotates in reverse to drive the sliding frame back to the original side. By rotating repeatedly in this way, the cable is guided to be evenly wound around the winding rod, avoiding the mutual crossing and overlapping of cables, ensuring the winding quality to reduce the wear and failure rate of the cable in subsequent use, so as to achieve the purpose that the winding device can guide the winding direction of the cable.

[0020] By installing a hydraulic rod on one side of the second fixed block, when installing the winding rod, the hydraulic rod can first move the second fixed block away from the first fixed block to provide sufficient installation space for the winding rod. Align the card slots on the winding rod with the clamping blocks on the first fixed block and the second fixed block, and then start the hydraulic rod to clamp and fix the winding rod simultaneously with the first fixed block and the second fixed block. The second servo motor starts to drive the rotation of the first fixed block through the transmission of the rotating shaft and the conveyor belt. The clamping connection between the clamping block and the card slot ensures that the winding rod rotates together. When the winding rod needs to be replaced, only need to start the hydraulic rod to contract, and then the winding rod can be disassembled. The operation is simple and fast, so as to achieve the purpose that the winding device can quickly replace the winding rod. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5, an embodiment provided by the present utility model: a winding device for processing low-smoke and halogen-free polyolefin fire-resistant cables, including a support frame 1.

[0029] A lifting structure 2 is welded to the top of the support frame 1. The lifting structure 2 includes a first support rod 201, a second support rod 202, a longitudinal threaded rod 203 and a turntable 204. The first support rod 201 is welded to one side of the top of the support frame 1, and the second support rod 202 is welded to the other side of the top of the support frame 1. The longitudinal threaded rod 203 penetrates through the inside of the second support rod 202, and the turntable 204 is welded to the top of the longitudinal threaded rod 203.

[0030] Refer to the attached Figure 1 and the attached Figures 4-5 As shown, rotating the turntable 204 drives the longitudinal threaded rod 203 to rotate in the second support rod 202. Since sliding grooves are provided on both sides of the sliding transverse groove 301 and sliders are provided inside the first support rod 201 and the second support rod 202, the sliding transverse groove 301 can be stably lifted and lowered inside the first support rod 201 and the second support rod 202, thereby changing the relative position between the guide wheel 305 and the winding rod 8. By changing the cable winding direction, the winding tightness is changed, avoiding wear, deformation or even rupture or sliding and winding of the cables caused by over-tight or over-loose winding, and ensuring the quality of cable winding.

[0031] A guiding mechanism 3 is installed inside the lifting structure 2. The guiding mechanism 3 includes a sliding transverse groove 301, a first servo motor 302, a transverse threaded rod 303, a sliding frame 304 and a guide wheel 305. The sliding transverse groove 301 is clamped inside the lifting structure 2. A slider is provided inside the first support rod 201. Sliding grooves are provided at both ends of one side of the sliding transverse groove 301. The sliding transverse groove 301 is slidably connected to the first support rod 201. A first servo motor 302 is fixedly installed on one side inside the sliding transverse groove 301. The transverse threaded rod 303 penetrates through the inside of the sliding transverse groove 301. A sliding frame 304 is movably installed on the outside of the transverse threaded rod 303. External threads are uniformly provided on the outer side wall of the transverse threaded rod 303, and internal threads that cooperate with the external threads are uniformly provided on the inner side wall of the sliding frame 304. The transverse threaded rod 303 is threadedly connected to the sliding frame 304. The guide wheel 305 is rotatably connected to the inside of the sliding frame 304.

[0032] Refer to the attached Figure 1 and the attached Figures 4-5As shown in the figure, a sliding cross groove 301 is installed in the middle of the first support rod 201 and the second support rod 202.

The cable to be wound needs to pass through between two guide wheels 305 first. The guide wheels 305 can rotate to ensure the smoothness of cable winding. The first servo motor 302 first rotates forward to move the sliding frame 304 to one side, and then rotates in reverse to drive the sliding frame 304 back to the original side. By rotating repeatedly in this way, the cable is guided to be evenly wound on the winding rod 8, avoiding the mutual crossing and overlapping of cables, ensuring the winding quality, and reducing the wear and failure rate of the cable during subsequent use.

[0035] Refer to the appendix Figures 1-4 As shown in the figure, a hydraulic rod 703 is installed on one side of the second fixing block 702. When installing the winding rod 8, the hydraulic rod 703 can first move the second fixing block 702 away from the first fixing block 701 to provide sufficient installation space for the winding rod 8. Align the card slots on the winding rod 8 with the clamping blocks 704 on the first fixing block 701 and the second fixing block 702 and start the hydraulic rod 703 to simultaneously clamp and fix the winding rod 8 by the first fixing block 701 and the second fixing block 702. When the second servo motor 4 is started, the first fixing block 701 is driven to rotate through the transmission of the rotating shaft 5 and the conveyor belt 6. The clamping connection between the clamping blocks 704 and the card slots ensures that the winding rod 8 rotates together. When the winding rod 8 needs to be replaced, only need to start the hydraulic rod 703 to contract, and the winding rod 8 can be disassembled, and the operation is simple and fast.
