Description

Technical Field

[0001] The present invention relates to the technical field of cable production, and particularly relates to a production process and device for a fireproof and compression-resistant cable. Background Art

[0002] Currently, in the production of fireproof and compression-resistant cables, it is necessary to sleeved fireproof and compression-resistant materials outside the cable, so as to protect the cable safely in case of a fire. Before sleeving the fireproof and compression-resistant materials, powder needs to be applied outside the cable to improve the adhesion of the fireproof and compression-resistant materials. Currently, a man-machine cooperation method is used for application. First, the equipment quickly applies the powder, and then the worker completes the areas that the equipment fails to apply. This requires a large amount of labor and increases the production cost.

[0003] In the prior art, multiple nozzles are arranged in a surrounding manner; the cable passes through between the multiple nozzles; then, the powder is fed into the conveying ring through the feeding joint, and the powder in the conveying ring is sprayed onto the cable through the nozzles, thereby realizing the automatic powder application operation on the cable.

[0004] However, in the aforementioned prior art, when applying the coating by spraying the powder, if the moving speed of the cable between the multiple nozzles is too fast, the sprayed powder cannot be timely attached to the outer wall of the cable; this limits the powder application efficiency of the cable. Therefore, in the prior art, in order to ensure that the powder is uniform and the applied amount meets the qualified requirements, the cable can only slowly pass through between the multiple nozzles, greatly reducing the powder application efficiency of the cable, which is particularly inconvenient for the powder application operation in the mass production of cables.

Detailed implementation manners

[0042] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] Please refer to Figures 1 to 9, the present invention provides a fireproof and compression-resistant cable production device, including a box body 1, a cable 2, a plurality of guiding units, two clamping units and a powder coating assembly. The box body 1 has a through hole 3. The powder coating assembly includes a powder storage box 4, a pressing roller 5 and a limiting wheel 6. The guiding unit includes a supporting member 7 and a guiding wheel 8. The clamping unit includes a top moving member 9, a first lifting member 10, a U-shaped plate 11 and two clamping mechanisms. The clamping mechanism includes a clamping member 12, a clamping plate 13 and a supporting plate 14. The powder coating assembly further includes two pressing units. The pressing unit includes a pressing member 15 and a supporting block 16. The powder coating assembly further includes a feeding assisting unit. The feeding assisting unit includes two telescopic members 17, two lifting electric slide rails 18 and a feeding groove 19. The powder coating assembly further includes a powder conveying unit. The powder conveying unit includes a powder conveying channel 20, a screw conveyor 21, a powder inlet 22 and a powder outlet 23. The powder coating assembly further includes a leveling unit. The leveling unit includes an annular slide rail 24, a ring body 25, a driving member 26, a gear 27, a toothed ring 28 and a plurality of coating mechanisms. The coating mechanism includes an adjusting member 29, a rotating member 30 and a coating brush 31. The powder coating assembly further includes a collecting unit. The collecting unit includes two bottom moving members 32, a connecting plate 33, a plurality of second lifting members 34, a scraping plate 35 and a collecting box 36. The box body 1 has a discharging port 37.

[0044] Among them, the box body 1 has a through hole 3, and the cable 2 passes through the through hole 3 and is located inside the box body 1. A plurality of the guiding units are sequentially arranged around the outside of the through hole 3. Two of the clamping units are sequentially arranged on the inner top wall of the box body 1. The powder storage box 4 is placed on the inner bottom wall of the box body 1. The pressing roller 5 is arranged inside the powder storage box 4. The limiting wheel 6 is sleeved outside the pressing roller 5, and the limiting wheel 6 is adapted to the cable 2. A pay-off reel is placed at one end of the guiding unit of the box body 1, and a take-up reel is placed at the other end to convey the cable 2. Under the guidance of the guiding unit, the cable 2 passes through the through hole 3 and enters the inside of the box body 1. One end of the cable 2 is clamped and fixed by the clamping unit. The pressing roller 5 moves downward, and the limiting wheel 6 is adapted to the cable 2, pressing the cable 2 into the powder storage box 4 so that it is wrapped with powder. Through the docking of the two clamping units, the cable 2 is moved to the take-up reel to quickly convey the cable 2, and the cable 2 continuously contacts the powder in the powder storage box 4 to complete the powder coating operation.

[0045] Secondly, the abutting member 7 is disposed at one end of the box body 1 and is located outside the through hole 3. The guide wheel 8 is rotatably connected to the output end of the abutting member 7, and a plurality of the guide wheels 8 are sequentially distributed around the outer wall of the cable 2. The abutting member 7 is a cylinder. When the abutting member 7 is activated, it drives the guide wheel 8 to abut the cable 2 passing through the through hole 3. When the cable 2 is conveyed, the guide wheel 8 rotates accordingly, thereby playing a limiting role on the cable 2 and preventing it from shifting during the conveying process.

[0046] Meanwhile, the top moving member 9 is disposed on the inner top wall of the box body 1, the first lifting member 10 is disposed at the output end of the top moving member 9, the output end of the first lifting member 10 is fixedly connected to the U-shaped plate 11, and two clamping mechanisms are symmetrically disposed on the U-shaped plate 11. The top moving member 9 is an electric slide rail, and the first lifting member 10 is a cylinder. When the top moving member 9 is activated, it drives the clamping mechanism to approach the through hole 3, thereby clamping the cable 2 entering the through hole 3; when the first lifting member is activated, the clamping height is adjusted, and then the clamping mechanism is activated to complete the clamping.

[0047] In addition, the clamping member 12 is disposed on one side of the U-shaped plate 11. The output end of the clamping member 12 penetrates through the U-shaped plate 11 and is fixedly connected to the clamping plate 13. The support plate 14 is disposed below the clamping plate 13. The clamping member 12 is a cylinder. When the clamping member 12 is activated, it drives the clamping plate 13 to clamp the cable 2. At the same time, the support plate 14 supports the lower part of the cable 2 to prevent the front end of the cable 2 from being too long and bending downward after clamping; or when the cable 2 passes through the through hole 3, the front end will bend downward due to being too long. At this time, when clamping, first move the support plate 14 under the cable 2, and then move it upward and clamp the cable 2. Thus, the support plate 14 can lift the cable 2 with a bent front end to avoid the difficulty in subsequent docking with another clamping unit due to the bending.

[0048] Then, two pressing units are symmetrically disposed on the box body 1; the pressing member 15 is disposed on the inner top wall of the box body 1, the output end of the pressing member 15 is fixedly connected to the support block 16, and both ends of the pressing roller 5 are rotatably connected to the corresponding support blocks 16. The pressing member 15 is a cylinder. When the pressing member 15 is activated, it drives the support block 16 to move downward, causing the pressing roller 5 to move downward and press the cable 2. At the same time, during the conveying process of the cable 2, when it contacts the limiting wheel 6, it can drive the pressing roller 5 to rotate on the support block 16, avoiding abrasion of the cable 2.

[0049] Again, the feeding auxiliary unit is arranged inside the box body 1; the two telescopic components 17 are sequentially arranged on one side of the box body 1, and the output ends of the two telescopic components 17 penetrate through the box body 1 and are respectively fixedly connected to the corresponding lifting electric slide rails 18. The output ends of the two lifting electric slide rails 18 are fixedly connected to one side of the feeding groove 19. Before transporting the cable 2, the pressing roller 5 is moved upward and stored to make room for the feeding groove 19. At this time, the telescopic component 17 is activated to drive the lifting electric slide rail 18 to move, so that the feeding groove 19 is docked with the through hole 3. At this time, after the cable 2 passes through the through hole 3, it needs to be guided by the feeding groove 19, and then the front end is clamped and moved by the clamping unit. Finally, the pressing roller 5 is moved downward to press the cable 2 into the powder storage box 4. Thus, through the guidance of the feeding groove 19, the problem that the moving trajectories of the clamping unit and the pressing unit conflict with each other can be avoided, and at the same time, the feeding docking operation of the cable 2 can be better carried out without manual feeding.

[0050] Moreover, the powder conveying unit is arranged on one side of the powder storage box 4; the powder conveying channel 20 is arranged on one side of the powder storage box 4. There is a powder inlet 22 between the powder conveying channel 20 and the powder storage box 4, and a powder outlet 23 is arranged above the powder conveying channel 20. The screw conveyor 21 is arranged inside the powder conveying channel 20. The powder in the powder storage box 4 enters the powder conveying channel 20 through the powder inlet 22. The screw conveyor 21 is activated to convey the powder above the powder storage box 4, and then it falls through the powder outlet 23 and returns to the inside of the powder storage box 4. Thus, the powder is circularly conveyed, and the powder falls from above the cable 2 to make better contact with the cable 2 during the conveying process, improving the powder adhesion rate; the continuously falling powder can also better wrap the cable 2; it can avoid the situation that when the cable 2 is pressed down, due to the large accumulation of powder in the powder storage box 4 and the cable 2 cannot completely enter the powder, resulting in incomplete powder wrapping.

[0051] Furthermore, the uniform unit is arranged inside the box body 1; the annular slide rail 24 is arranged inside the box body 1, the ring body 25 is slidably connected to the annular slide rail 24 and is located inside the annular slide rail 24, the driving component 26 is arranged inside the box body 1 and is located on one side of the ring body 25, the gear 27 is arranged at the output end of the driving component 26, the toothed ring 28 is arranged on one side of the ring body 25, the toothed ring 28 meshes with the gear 27, and a plurality of the coating mechanisms are sequentially distributed on the other side of the ring body 25; the adjusting component 29 is arranged on the other side of the ring body 25, the output end of the adjusting component 29 is fixedly connected to the rotating component 30, and the output end of the rotating component 30 is fixedly connected to the coating brush 31. The annular slide rail 24 supports the ring body 25, the driving component 26 is a motor. When the cable 2 needs to pass through the ring body 25 and be docked with the winder at the other end of the box body 1, first move the two clamping units to both sides of the ring body 25 respectively, then move the pallet 14 holding the cable 2 close to the ring body 25, pass the front end of the cable 2 through the ring body 25. At this time, the clamping plate 13 on the other side of the ring body 25 clamps the cable 2 on the pallet 14, and then continues to convey it, so that it can pass through the ring body 25 to complete the docking operation of the cable 2, and there is no need for manual participation, and the cable 2 is automatically conveyed, avoiding the ring body 25 from hindering the cable 2 from passing through the inside of the box body 1;

[0052] When coating: the driving component 26 is started to drive the gear 27 to rotate, which cooperates with the toothed ring 28 to drive the ring body 25 to rotate on the annular slide rail 24, thereby driving a plurality of the coating mechanisms to rotate, and coating the outside of the cable 2 in a surrounding manner, so as to additionally coat the attached powder and avoid uneven distribution of the powder on the outer wall of the cable 2; in addition, the adjusting component 29 is a cylinder, the rotating component 30 is a motor, when the adjusting component 29 is started, it can drive the coating brush 31 to move telescopically to adapt to cables 2 of different sizes, and the rotating component 30 drives the coating brush 31 to rotate, which can better coat the powder.

[0053] Finally, the collecting unit is arranged inside the box body 1; the box body 1 has a discharge port 37, both of the two bottom moving components 32 are arranged at the inner bottom of the box body 1, the connecting plate 33 is fixedly connected to the output ends of the two bottom moving components 32, a plurality of the second lifting components 34 are sequentially arranged below the connecting plate 33, the output ends of the plurality of the second lifting components 34 are all fixedly connected to the scraping plate 35, and the collecting box 36 is placed below the discharge port 37. The bottom moving component 32 is an electric slide rail, the second lifting component 34 is a cylinder, and the connecting plate 33 supports the second lifting component 34;

[0054] The bottom moving part 32 is activated to drive the scraping plate 35 to scrape the inner bottom wall of the box body 1, and the scattered powder above can be scraped to the discharge port 37 and then fall into the collection box 36 for collection so as to be recycled and reused.

[0055] When scraping powder: after the scraping plate 35 scrapes from left to right once, the second lifting part 34 drives the scraping plate 35 to move upward so that the scraping plate 35 does not contact the inner bottom wall of the box body 1, and then it moves to the left and scrapes to the right again. By repeating this operation, it can be avoided that the scraping plate 35 accidentally scrapes the powder to the left side of the box body 1.

[0056] When using a fireproof and pressure-resistant cable production device of this embodiment, a pay-off reel is placed at one end of the guiding unit of the box body 1, and a take-up reel is placed at the other end to convey the cable 2; with the assistance of the guiding wheel 8, the cable 2 of different sizes is held against, and the cable 2 passes through the through hole 3 and enters the interior of the box body 1; the clamping plate 13 clamps and fixes one end of the cable 2, then the pressing roller 5 moves downward, the limiting wheel 6 is adapted to the cable 2, and the cable 2 is pressed into the powder storage box 4 so that it is wrapped with powder; then through the docking of the two clamping units, the cable 2 is moved to the take-up reel, and further the cable 2 is conveyed quickly. The cable 2 continuously contacts the powder in the powder storage box 4 to complete the powder adhesion operation. At the same time, the powder in the powder storage box 4 enters the powder conveying channel 20 through the powder inlet 22, the screw conveyor 21 is activated to convey the powder above the powder storage box 4, and then it falls through the powder outlet 23 and returns to the interior of the powder storage box 4. Thus, the powder is circularly conveyed, and the powder falls from above the cable 2 to make it better contact with the cable 2 during the conveying process, improving the powder adhesion rate; it can also better wrap the cable 2 with the continuously falling powder; it is avoided that when the cable 2 is pressed down, due to the excessive accumulation of powder in the powder storage box 4 and it cannot completely enter the powder, resulting in incomplete powder wrapping; in addition, during coating: the driving part 26 is activated to drive the gear 27 to rotate, cooperate with the toothed ring 28, and drive the ring body 25 to rotate on the annular slide rail 24, thereby driving a plurality of coating mechanisms to rotate and circumferentially coat the outside of the cable 2, so as to additionally coat the adhered powder and avoid uneven distribution of the powder adhered to the outer wall of the cable 2; in addition, the adjusting part 29 is a cylinder, the rotating part 30 is a motor, the adjusting part 29 is activated, which can drive the coating brush 31 to telescopically move to adapt to cables 2 of different sizes, and the rotating part 30 drives the coating brush 31 to rotate, which can better coat the powder, and then a fireproof and pressure-resistant material can be installed and sleeved outside the cable 2 subsequently.

[0057] With the above structural arrangement, by pressing the cable 2 into the powder storage box and making full contact with the powder, the cable 2 is conveyed while being wrapped by the powder. Thus, the powder coating is not affected by the spraying speed and spraying amount. Even when the cable 2 is conveyed rapidly, the powder can effectively adhere, greatly improving the powder coating efficiency of the cable 2.
