Description

Technical Field

[0001] The invention relates to the field of cable production and manufacturing, and in particular to an improved wrapping device for producing flexible fireproof cables. Background Art

[0002] Cables are devices that transmit electrical energy or signals, typically consisting of several conductors or groups of conductors. During cable production, they require mica wrapping to provide better cable protection. This often requires the use of wrapping machines, which are specialized equipment for producing fire-resistant cables, control cables, and communication cables. Traditional wrapping machines, however, are complex in structure and rotate the cable during production, which can easily damage the cable and result in poor wrapping quality.

[0003] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0014] The wrapping assembly includes a mounting ring, a mounting post arranged on the mounting ring for mounting a mica tape roll, a driven tooth arranged on an outer side wall of the mounting ring, and a driving motor matched with the driving tooth.

[0015] The present invention realizes intelligent wrapping of the mica tape through a wrapping assembly consisting of a mounting ring, a mounting column, a driving tooth and a driving motor group, thereby achieving the purpose of improving the wrapping quality and ensuring the production quality of the cable.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0035] The present invention provides an improved wrapping device for the production of flexible fire-resistant cables. Its working principle is to improve the fire resistance of the cable and extend the service life of the cable by adding a mica tape layer on the conductor and arranging a layer of foamed ceramic silicon refractory mica layer in the protective component; the fire resistance of the cable is increased by using highly flame-retardant and environmentally friendly materials and ceramic differential composition fillers, and the strength of the internal wire body of the cable is also increased, which reduces the degree of corrosion of the wire body during long-term use.

[0036] The present invention will be further described in detail below with reference to examples and specific implementation methods.

[0037] like Figure 1-Figure 2 As shown, an improved flexible fire-resistant cable comprises an inner rod 1, a plurality of unit wire bodies arranged around the inner rod and a protective component wrapping the unit wire bodies; a filler composed of a differential mixture of highly flame-retardant and environmentally friendly materials and ceramics is arranged between the unit wire bodies and the protective component; the unit wire bodies are distributed on the peripheral side walls of the inner rod.

[0038] The inner rod is provided with a plurality of mounting grooves 11 on the side walls thereof. The mounting grooves are detachably provided with support plates 12. Three support plates are used in the present invention to support the protective assembly and improve the overall strength of the cable.

[0039] The unit line body is cylindrical in shape and includes a conductor 21. The conductor is wrapped with a silicone tape layer 22, a mica tape layer 23 (in this embodiment, there are six layers of mica tape; those skilled in the art can select the appropriate number of layers based on actual production requirements) and an isolation sleeve layer 24.

[0040] The protective assembly comprises, from the inside out, a non-woven fabric layer 31, a metal mesh layer 32, a foamed ceramic silicon refractory mica layer 33 [in this embodiment, there are two layers of foamed ceramic silicon refractory mica; those skilled in the art can select the appropriate number of layers based on actual production requirements], and a halogen-free protective sleeve 34. By adding a mica tape layer to the conductor and positioning the foamed ceramic silicon refractory mica layer within the protective assembly, the foamed ceramic silicon refractory mica tape burns into a hard ceramic foam shell in the event of a fire, effectively isolating the flame from the heat transfer, effectively protecting the cable core, reducing the cable core temperature, and extending the service life of the entire cable.

[0041] like Figure 3-Figure 4As shown, a wrapping device suitable for an improved flexible fire-resistant cable comprises a base 4, a vertical mounting plate 5 disposed on the base, a through hole 6 disposed in the center of the vertical mounting plate for the conductor to pass through, a wrapping assembly disposed on the vertical mounting plate for wrapping the conductor, and a support assembly for mounting the wrapping assembly;

[0042] The wrapping assembly includes a mounting ring 71, a mounting post 72 arranged on the mounting ring for mounting a mica tape roll, a driven tooth 73 arranged on the outer wall of the mounting ring, a driving motor (not shown, the driving gear 74 in the middle is installed on the driving shaft of the driving motor) that cooperates with the driving tooth, four support rods 75 arranged between the mounting ring and the vertical mounting plate, and a sphere 76 arranged at the top of the support rod; a support groove is provided on the back of the mounting ring, and the sphere rests on the surface of the support groove.

[0043] The support assembly includes a crossbeam 81 mounted above the base, a support groove 82 provided on the surface of the mounting ring, and an L-shaped support rod 83 provided in the support groove;

[0044] There are four L-shaped support rods in total, two of which are installed on the crossbeam, and the other two are installed on the base.

[0045] The specific steps of using the wrapping device in the present invention are as follows: Figure 3 and Figure 4 As shown, the mica roll 9 is placed on the mounting post 72 and the locking screw at the end of the mounting post is tightened (the diameter of the locking screw nut is larger than the diameter of the mica roll shaft). When winding begins, the cable group is continuously fed out of the through hole 6, and the drive motor is started, driving the mounting ring to rotate via the drive gear 74 (the presence of the four support rods 83 and support grooves 82 ensures that the mounting ring will not skew during rotation), thereby continuously wrapping the mica roll around the cable, thereby ensuring wrapping continuity.

[0046] At the same time, the presence of the support rod 75 and the L-row support rod 83 can ensure that the installation ring is in a unique vertical plane, further avoiding the back and forth shaking during the rotation of the installation ring, and ensuring the stability of the wrapping. At the same time, since support grooves are provided on the two ground surfaces of the installation ring and a rollable sphere is provided at the end of the support rod, the friction between the installation ring and the support rod and the L-shaped support rod during the rotation is further reduced, thereby extending the use of the installation ring.

[0047] Through the above method, the present invention provides an improved flexible fire-resistant cable production wrapping device, which achieves the purpose of improving the fire resistance of the cable and extending the service life of the cable by adding a mica tape layer on the conductor and arranging a layer of foamed ceramic silicon refractory mica layer in the protective component; the fire resistance of the cable is increased by using highly flame-retardant and environmentally friendly materials and ceramic differential composition fillers, and the strength of the internal wire body of the cable is also increased, which reduces the degree of corrosion of the wire body during long-term use.

[0048] The above is only a preferred embodiment of the improved flexible fire-resistant cable production wrapping device disclosed in the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
