Description

Technical Field

[0001] The utility model relates to the field of cable wrapping equipment, in particular to a stable wrapping mould for special cables. Background Art

[0002] The tape used in the wrapping process of special cables is different from the ordinary cable tape. It has many advantages such as high strength, long elongation, and good toughness, thus meeting the relevant requirements of special cables. The wrapping process refers to the process of spirally wrapping the tape around the cable surface through the circular motion of the wrapping head of the wrapping machine and the linear motion of traction. The wrapping methods include gap wrapping, seam wrapping, and overlapping wrapping. The wrapping process of special cables requires the tape to be compact, the overlap rate to be uniform, and the tape to be wrinkle-free. At the same time, some special cables have a small outer diameter, and the production speed is fast in the wrapping process, and the cable wrapping shakes greatly. How to ensure that the tape is stable and evenly overlapped on the cable surface is a difficult problem.

[0003] The Chinese patent with announcement number CN209895843U discloses a wrapping mold, which sets the wrapping process inside the mold to improve the wrapping accuracy. The mold is mounted on the wrapping device through an external fixture for rotation. Due to different cable sizes, when the processed cable is replaced, the corresponding mold is different, and adjustment is required at this time, which increases the processing time and is not conducive to production. At the same time, since the mold has the characteristics of lightweight, long-term direct clamping will affect the service life of the mold, causing the mold to deform, and then affect the cable quality. During use, since the wrapping belt is fixed in position, the mold position needs to be adjusted. The existing technology is inconvenient to adjust, which will affect the wrapping quality.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 6As shown, the stable wrapping mold for special cables of this embodiment includes an upper mold 2 and a lower mold 3. A wire passage 41 is provided between the upper mold 2 and the lower mold 3. A tape inlet 42 is provided on the upper mold 2 and the lower mold 3. A connecting structure 5 is provided at both ends of the upper mold 2 and the lower mold 3. A fixing sleeve 1 is installed on the connecting structure 5. The fixing sleeves 1 at both ends of the stable wrapping mold are respectively fixedly connected to the wrapping machine, and an inner mold is installed inside the fixing sleeve 1 for stable cable wrapping.

[0027] The connecting structure 5 comprises an outer mounting section 51 , and a plurality of outer positioning holes 52 are arranged on the outer mounting section 51 .

[0028] The fixing sleeve 1 includes an abutting ring 11, an inner mounting section 12, a shoulder 13 and a connecting section 14. The connecting section 14 is provided with a positioning pin hole 15. The inner mounting section 12 is provided with a plurality of inner positioning holes 16. The abutting ring 11 wraps the ends of the upper mold 2 and the lower mold 3. The inner mounting section 12 cooperates with the outer mounting section 51. Positioning bolts 6 are provided in the outer positioning holes 52 and the inner positioning holes 16. One end of the fixing sleeve 1 is fixedly connected to the wrapping machine through the positioning pin hole 15, and the other end is fixedly connected to the inner upper mold 2 and the inner lower mold 3 through the inner positioning holes 16 distributed circumferentially. The shoulder 13 is used for installation and positioning.

[0029] A plurality of inner positioning holes 16 are evenly distributed on the inner mounting section 12, and a plurality of outer positioning holes 52 are evenly distributed on the outer mounting section 51. The inner positioning holes 16 are distributed in a circumferential manner with a gap of 15° or 20°, so as to accurately position and connect with the inner upper mold 2 and the inner lower mold 3, and the relative positions of the inner upper mold 2 and the inner lower mold 3 can be adjusted according to actual conditions. The method of using multiple positioning points is intended to adjust the relative positions of the upper mold 2 and the lower mold 3 while adjusting the wrapping angle, and to lock the upper mold 2 and the lower mold 3 inside the outer mold sleeve 1 using two positioning bolts 6.

[0030] The inner mounting section 12 is provided with a sinking groove, and the inner positioning holes 16 are distributed in the sinking groove. The sinking groove can be used to place the head of the positioning bolt 6.
