Description

Technical Field

[0001] The utility model relates to the technical field of cable wrapping, in particular to a wrapping machine. Background Art

[0002] In the cable production industry, the process of winding a wrapping tape around the cable core is often involved. The wrapping tape, such as mica tape, polyester film tape, aluminum foil tape, cotton paper tape, etc., plays a role of shielding, insulation or flame retardancy according to the different properties and process requirements of the wrapping tape. The wrapping tape is usually wound around the inner lining cylinder and processed into a disc-shaped structure. The disc-shaped wrapping tape is not driven to rotate on the wrapping machine, and then the wrapping tape is wound around the cable. At present, in actual operation, the rotation speed of the disc-shaped wrapping tape on the wrapping machine is fixed, and the moving speed of the cable is also fixed, which causes the wrapping pitch of the tape on the cable to be fixed. When wrapping different cable tapes, the wrapping pitch of the cable cannot be changed according to actual needs, and cannot meet the requirements of different cables. Utility Model Content

[0010] Preferably, a plurality of clamping rods are equidistantly and fixedly provided on opposite sides of the two fixing plates, and the plurality of clamping rods on the same fixing plate are all arranged toward the threaded rod.

[0011] The wrapping machine proposed by the utility model has the beneficial effect that when the wrapping machine is in use, the two clamping mechanisms both clamp disc-shaped wrapping tapes, and the speed at which the cylinder is driven to rotate by the stepless speed change mechanism can be adjusted by forward or reverse rotation of the fixed shaft, thereby adjusting the rotation speed of the two disc-shaped wrapping tapes clamped by the two clamping mechanisms on the disc, and when the moving speed of the cable passing through the threading tube remains unchanged, the wrapping pitch of the tape on the cable can be adjusted to meet the wrapping requirements of different cables, and in addition, the stepless speed change mechanism can be placed in a neutral state by a fixed shaft, and when the neutral gear is engaged, the disc can be manually rotated at will to adjust the position of the two clamping mechanisms, so that the worker can replace the disc-shaped wrapping tapes on the two clamping mechanisms while standing still, which is convenient for the worker's operation.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 1 , 45, a wrapping machine, comprising a shell 1, a continuously variable speed mechanism is fixed inside the shell 1, a fixed shaft 5 and a cylinder 3 are fixed on the continuously variable speed mechanism, the fixed shaft 5 and the cylinder 3 are both arranged through the shell 1, and the fixed shaft 5 and the shell 1, and the cylinder 3 and the shell 1 are all arranged to rotate, a hand wheel 6 is fixed on the fixed shaft 5 outside the shell 1, and the continuously variable speed mechanism can be adjusted through the fixed shaft 5 by forward or reverse rotation of the hand wheel 6, thereby adjusting the rotation speed of the continuously variable speed mechanism driving the cylinder 3, and the continuously variable speed mechanism can also be placed in a neutral state, and the cylinder 3 can be manually rotated to allow the cylinder 3 to rotate at will;

[0021] A threading tube 2 is provided in the cylinder 3 so as to pass through and rotate. The threading tube 2 passes through the outer shell 1 and is fixed on the outer shell 1. The cable to be wrapped passes through the threading tube 2. Although the threading tube 2 is fixed on the outer shell 1, it will not affect the rotation of the cylinder 3 driven by the stepless speed change mechanism. A disk 4 is fixed on the cylinder 3 and rotates with the rotation of the cylinder 3. Two clamping mechanisms are symmetrically fixed on the disk 4. The two clamping mechanisms are used to clamp the disc-shaped wrapping tape so that the two clamped disc-shaped wrapping tapes rotate together with the disk 4.

[0022] When in use, the two clamping mechanisms both clamp a disc-shaped wrapping tape. The speed at which the cylinder 3 is driven to rotate by the stepless speed change mechanism can be adjusted by rotating the fixed shaft 5 forward or reversely, thereby adjusting the rotation speed of the two disc-shaped wrapping tapes clamped by the two clamping mechanisms on the disc 4. When the moving speed of the cable passing through the threading tube 2 remains unchanged, the wrapping pitch of the tape on the cable can be adjusted to meet the wrapping requirements of different cables. In addition, the stepless speed change mechanism can be placed in a neutral state through a fixed shaft. When the neutral gear is engaged, the disc 4 can be rotated manually at will to adjust the position of the two clamping mechanisms, so that the worker can replace the disc-shaped wrapping tapes on the two clamping mechanisms while standing still, which is convenient for the worker's operation.

[0023] Example 2

[0024] Based on Example 1, Figure 1 , 2 , 3 and 5, as another preferred embodiment of the utility model, the difference from embodiment 1 is that the clamping mechanism includes a fixing rod 7, a threaded rod 8 is fixed on the fixing rod 7, two fixing plates 9 are set on the threaded rod 8, each fixing plate 9 is penetrated by a threaded hole 12, the threaded rod 8 and the threaded hole 12 are engaged, the two fixing plates 9 can rotate on the threaded rod 8, the fixing rod 7 is tilted and fixed on the disc 4, which makes the disc-shaped wrapping tape set on the two threaded rods 8 in an eight-shaped arrangement, and the small mouth faces the disc 4, and a plurality of baffles 10 are evenly fixed on the circumferential surface of each fixing plate 9;

[0025] A plurality of clamping rods 13 are equidistantly and fixedly provided on opposite sides of the two fixing plates 9. The plurality of clamping rods 13 on the same fixing plate 9 are all arranged toward the threaded rod 8. When clamping the disc-shaped wrapping tape, the plurality of clamping rods 13 on the two fixing plates 9 rest against the inner lining cylinder inside the clamped disc-shaped wrapping tape, so that the disc-shaped wrapping tape and the threaded rod 8 will not rotate relative to each other, thereby ensuring the tightness of the cable tape.

[0026] When in use, the fixing plate 9 away from the disc 4 is twisted to remove the fixing plate 9 from the threaded rod 8, the lining cylinder on the disc-shaped wrapping tape is put on the threaded rod 8, and the removed fixing plate 9 is installed back on the threaded rod 8, and the fixing plate 9 is twisted to bring the two fixing plates 9 closer to each other until the multiple clamping rods 13 on the two fixing plates 9 are against the two sides of the lining cylinder on the disc-shaped wrapping tape, the disc-shaped wrapping tape is limited on the threaded rod 8, and when the threaded rod 8 drives the disc-shaped wrapping tape to rotate, the tape on the disc-shaped wrapping tape is smoothly pulled out.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
