Description

Technical Field

[0001] This utility model relates to the field of metal strip wrapping technology, and in particular, to a protective mechanism for steel strip wrapping, a strip feeding machine, and armored wrapping equipment. Background Technology

[0002] Armor wrapping equipment is a type of cable manufacturing equipment, mainly used to wrap metal strips (such as copper strips, steel strips, aluminum strips, etc.) around cables to provide mechanical protection. The protective layer formed by the metal strips can enhance the mechanical strength of the cable on the one hand, and prevent external factors from damaging the inside of the cable on the other hand, thus extending the service life of the cable.

[0003] Armor wrapping equipment generally includes a tape unwinding machine for releasing the tape and a wrapping machine for wrapping the metal tape. During operation, the tape unwinding machine releases the metal tape wound around it, and the metal tape passes through the unwinding machine and enters the wrapping machine. Currently, the tape unwinding machine is usually located on one side of the metal tape inlet of the wrapping machine. To facilitate opening and closing the wrapping machine, a gap is usually provided between the tape unwinding machine and the wrapping machine for operator access. However, this gap leaves the metal tape, which is being transported from the tape unwinding machine to the wrapping machine, in an open and exposed state. Because the edges of the metal tape are very sharp, if a break occurs during the tape transport process, the broken section of the metal tape will fly out in any direction, easily causing injury to the operator. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, it is necessary to provide a protective mechanism for wrapping steel strips to prevent metal strips from breaking off and flying out and injuring operators.

[0005] It is also necessary to provide a tape feeding machine with a protective mechanism for wrapping the steel strip;

[0006] It is even more necessary to provide an armor wrapping device with the tape feeding machine.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a protective mechanism for wrapping steel strip, installed on the body of a strip feeding machine, including a protective cover, guide rollers and a rotating support assembly. One end of the protective cover is rotatably connected to the body of the strip feeding machine. The inner cavity of the protective cover forms a strip passage groove for the metal strip to pass through. Both opposite ends of the protective cover have openings communicating with the strip passage groove. The guide rollers are rotatably arranged near the openings at both ends of the protective cover.

[0014] This utility model also provides a tape feeding machine, including the protective mechanism for wrapping steel tape as described in any of the preceding claims, and a tape feeding machine body, wherein the protective mechanism for wrapping steel tape is installed on the tape feeding machine body.

[0015] Furthermore, the tape feeding machine body includes a housing and a tape reel, the tape reel is rotatably installed inside the housing, the protective cover is rotatably connected to the housing, and one end of the support rod is rotatably connected to the housing.

[0016] This utility model also provides an armor wrapping device, including a wrapping machine and a tape feeding machine as described in any of the preceding claims. The protective mechanism for wrapping the steel tape is located between the tape feeding machine body and the wrapping machine. The end of the protective cover away from the tape feeding machine body can move closer to or further away from the wrapping machine when the protective cover rotates.

[0017] The beneficial effects of this utility model are as follows: The protective mechanism for steel strip wrapping is installed between the tape feeding machine and the wrapping machine. The metal strip, which was originally exposed between the tape feeding machine and the wrapping machine, is now covered by the protective cover.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Please see Figures 1-4This utility model provides an armor wrapping device, including a tape release machine 100 and a wrapping machine 200. The tape release machine 100 is disposed on one side of the wrapping machine 200. The tape release machine 100 is used to release metal tape, and the wrapping machine 200 is used to receive the metal tape and wrap it around the cable. In this embodiment, the tape release machine 100 includes a tape release machine body 10 and a steel tape wrapping protective mechanism 20. The steel tape wrapping protective mechanism 20 is mounted on the tape release machine body 10 and located between the tape release machine body 10 and the wrapping machine 200. In use, the metal tape is released from the tape release machine body 10, passes through the steel tape wrapping protective mechanism 20, and enters the wrapping machine 200 to perform the cable wrapping operation.

[0026] The protective mechanism 20 for wrapping steel strip includes a protective cover 21, guide rollers 22, and a rotating support assembly 33. One end of the protective cover 21 is rotatably connected to the main body 10 of the tape feeding machine. The other end of the protective cover 21 can move closer to or further away from the wrapping machine when the protective cover 12 rotates. The inner cavity of the protective cover 21 forms a tape passage groove 215 for the metal strip to pass through. Both opposite ends of the protective cover 21 have openings 216 communicating with the tape passage groove 215. Guide rollers 22 are rotatably arranged near the openings 216 at both ends of the protective cover 21. The rotating support assembly 33 is installed between the main body 10 of the tape feeding machine and the protective cover 21 to drive the protective cover 21 to rotate and lock the protective cover 21.

[0027] During operation, the protective cover 21 is rotated to the open state relative to the tape feeding machine body 10, and its position is locked by the rotating support assembly 33. Then, the metal strip released by the tape feeding machine body 10 passes through the tape groove 215 and is pulled into the wrapping machine 200. Under the traction of the wrapping machine 200, the metal strip is continuously released from the tape feeding machine body 10 and passes through the protective cover 21 under the action of the guide roller 22. In the above process, the metal strip, which was originally exposed between the tape feeding machine body 10 and the wrapping machine 200, is covered by the protective cover 21. When the metal strip breaks during production, the protective cover 21 can prevent the broken metal strip from flying around and injuring the operator. When production stops, the protective cover 21 can be rotated to the retracted state. At this time, the steel strip wrapping protective mechanism 20 does not occupy too much space, making it convenient for the operator to pass between the tape feeding machine body 10 and the wrapping machine 200, and also facilitating the transportation of the tape feeding machine body 10.

[0028] In this embodiment, the protective cover 21 includes a lower cover 211 and an upper cover 212, which are disposed opposite to each other. The conveyor belt groove 215 is formed by the lower cover 211 and the upper cover 212. Guide rollers 22 are rotatably provided at both ends of the lower cover 211 and both ends of the upper cover 212. When the lower cover 211 and the upper cover 212 are disposed opposite to each other, the guide rollers 22 located at the corresponding ends of the lower cover 211 and the upper cover 212 are disposed opposite to each other, forming a channel for the metal strip to pass through.

[0029] In a preferred embodiment, one side of the upper cover 212 is rotatably connected to one side of the lower cover 211, specifically via a hinge. The operator can open and close the protective cover 21 by flipping it over, facilitating the passing of the metal strip through the protective cover 21 before processing. The upper cover 212 and the other side of the lower cover 211 can be detachably fixed together by means of snap-fit ​​or bolts, achieving a locking effect between the upper and lower covers and preventing them from easily separating.

[0030] In addition, multiple weight-reduction holes 210 are provided on both the upper cover 212 and the lower cover 211. While ensuring structural strength, the weight of the protective cover 21 can be reduced, thereby achieving lightweight production and making operation easier.

[0031] In this embodiment, the rotating support assembly 33 includes a support rod 331, a movable sleeve 332, and a locking member 333. The support rod 331 is located below the protective cover 21. One end of the support rod 331 is rotatably connected to the tape feeding machine body 10. The movable sleeve 332 is rotatably connected to the end of the protective cover 21 away from the tape feeding machine body 10. The movable sleeve 332 is sleeved on the outside of the support rod 331 and can slide along the length direction of the support rod 331. The locking member 333 is installed on the movable sleeve 332 and is used to lock the movable sleeve 332 on the support rod 331.

[0032] When in use, when the protective cover 21 rotates, the movable sleeve 332 slides along the length of the support rod 331. When the protective cover 21 rotates to the appropriate position, the operator can lock the movable sleeve 332 onto the support rod 331 through the locking piece 333. At this time, the protective cover 21 cannot rotate relative to the tape feeding machine body 10, that is, the position of the protective cover 21 is locked.

[0033] In this embodiment, two coaxial bushings 213 are fixedly installed at the bottom of the protective cover 21 away from the tape feeding machine body 10. A fixed shaft 214 is fixedly inserted between the two bushings 213. The movable sleeve 332 includes a first sleeve 3321 and a second sleeve 3322 fixedly connected. The first sleeve 3321 is rotatably sleeved on the end of the fixed shaft 214, and the second sleeve 3322 is slidably sleeved on the outside of the support rod 331. The central axes of the first sleeve 3321 and the second sleeve 3322 are perpendicular to each other. The second sleeve 3322 is a clamp structure. In this case, the locking element 333 is a bolt installed on the connecting ears on both sides of the clamp structure. In use, the bolt passes through the two connecting ears and is locked and fixed by the nut, thereby locking the second sleeve 3322 onto the support rod 331. In other embodiments not shown, the second sleeve 3322 may also be a cylindrical structure, and the locking member 333 is a locking bolt that is threadedly connected to the second sleeve 3322. During installation, the tail of the locking bolt passes through the wall of the second sleeve 3322 and abuts against the outer wall of the support rod 331, thereby locking the second sleeve 3322 onto the support rod 331.

[0034] In other embodiments not shown, the rotating support assembly 33 can also be a cylinder. In this case, the cylinder body end is rotatably connected to the side wall of the tape feeding machine body 10, and the cylinder extension end is rotatably connected to the bottom of the protective cover 21. Thus, the protective cover 21 can be driven to rotate by controlling the extension and retraction of the cylinder.

[0035] In this embodiment, the tape unloading machine body 10 includes a housing 11 and a tape reel 12. The tape reel 12 is rotatably mounted inside the housing 11, and a protective mechanism 20 for wrapping the steel tape is mounted on the side wall of the housing 11. Specifically, two parallel horizontal shafts are fixedly mounted on the side wall of the housing 11, with one horizontal shaft located above the other. The lower cover 211 is rotatably connected to the upper horizontal shaft, and one end of the support rod 331 is rotatably connected to the lower horizontal shaft. In use, the tape reel 12 rotates to release the metal tape wound on it. Further, two opposing guide wheels 13 are rotatably mounted on the housing 11 at the opening 216 of the protective cover 21. The two guide wheels 13 are arranged vertically, and the metal tape released from the tape reel 12 passes between the two guide wheels 13 and enters the protective cover 21.

[0036] In this embodiment, the wrapping machine 200 can be any commercially available wrapping machine, and the structure and working process of the wrapping machine will not be described in detail here.

[0037] The protective mechanism 20 for wrapping steel strip of this utility model is installed between the tape feeding machine body 10 and the wrapping machine 200. The metal strip, which was originally exposed between the tape feeding machine body 10 and the wrapping machine 200, is covered by the protective cover 21. When the metal strip breaks during production, the protective cover 21 can prevent the broken metal strip from flying around and injuring the operator. When production stops, the protective cover 21 can be rotated to a retracted state. At this time, the protective mechanism 20 for wrapping steel strip does not occupy too much space, making it convenient for the operator to pass between the tape feeding machine body 10 and the wrapping machine 200, and also facilitating the transportation of the tape feeding machine body 10.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
