[0002] In the cable production process, it is necessary to wrap the shielding tape around the exposed wire or cable core. For example, wrapping the shielding tape around the core wire of the cable can play the role of insulation, fire prevention, and shielding, and enhance the safety of cable use.

[0003] Most of the shielding wrapping machines in the prior art use their own power source to drive the shielding tape to rotate around the cable, so that the shielding tape is wrapped around the cable, and then the cable wrapped with the shielding tape is transported to the single twisting machine for the next process. During the shielding tape winding process, the shielding tape roll rotates with the power source, generating wind resistance, which affects the wrapping speed to a certain extent and wastes energy.

DETAILED DESCRIPTION

[0041] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0042] like Figure 1-Figure 6 The specific embodiment of the non-powered shielding wrapping machine of the utility model shown includes a frame 1, a cable 200 entry plate 2 and a cable 200 output plate 4 respectively installed at both ends of the frame 1, and also includes a plurality of entry holes 3 provided on the cable 200 entry plate 2 for inserting a plurality of cables 200; an exit hole 5 provided on the cable 200 output plate 4 for passing the cable 200 out; at least one package holding device 6, which is installed on the frame 1, and in this embodiment, is installed on the frame 1 on one side of the cable 200, and is used to place and output the shielding tape 100. It should be noted that when in use, the cable 200 to be wrapped with the shielding tape 100 passes through the entry hole 3 and the exit hole 5 in turn and is connected to the external single twisting machine, and the cable 200 is twisted and dragged by the single twisting machine to be twisted and moved in the direction of the single twisting machine.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the two ends of the frame 1 are provided with an entry hole 3 and an exit hole 5 for the cable 200, and the package support device 6 for placing the shielding tape 100 roll is arranged on one side of the cable 200. When wrapping the shielding tape 100, the shielding tape 100 roll does not rotate around the cable 200, but only needs to be rolled on the cable 200 from one side, and the cable 200 is twisted and dragged by the single twisting machine to move in the direction of the single twisting machine, so as to achieve stable wrapping of the shielding tape 100 and the cable 200. It should be further explained that the shielding tape in this embodiment can be one or more of an insulating polyester tape, a fire-resistant mica tape, and an aluminum foil tape.

[0044] As a preferred embodiment, Figure 2 and Figure 4As shown, a plurality of penetration holes 3 are distributed in a circular shape at equal intervals on the cable 200 entry plate 2, and the center of the circle formed by the plurality of penetration holes 3 and the line connecting the center of the circle formed by the plurality of penetration holes 3 and the line connecting the center of the circle formed by the plurality of penetration holes 3 and the line connecting the center of the circle formed by the plurality of penetration holes 5 are on the same horizontal plane, that is, the line connecting the center of the circle formed by the plurality of penetration holes 3 and the line connecting the center of the circle formed by the plurality of penetration holes 5 is parallel to the ground. The package support device 6 in this embodiment is arranged on one side of the cable 200, and comprises a support plate 61, a reel assembly 63, a tensioning assembly 64 and at least one guide wheel mounted on the frame 1 through a lifting assembly 62, wherein the reel assembly 63 is mounted on the support plate 61 for placing a roll of shielding tape 100, the tensioning assembly 64 is mounted on the frame 1 for tensioning the shielding tape 100 to be wound, and at least one guide wheel is mounted on the support plate 61 for guiding the tensioned shielding tape 100. When in use, the shielding tape 100 roll is placed on the reel assembly 63, and one end of the shielding tape 100 is wound around the tensioning assembly 64 and the guide wheel in sequence and then wound on the cable 200.

[0045] As an embodiment, the lifting assembly 62 includes a mounting seat 621 fixedly mounted on the frame 1 and a lifting shaft 622 threadedly connected to the mounting seat 621, and the upper end of the lifting shaft 622 is fixedly connected to the support plate 61. The lifting assembly 62 is configured to adjust the height of the support plate 61, that is, to adjust the height of the roll of the shielding tape 100 placed on the reel assembly 63, so as to adapt to different application scenarios. For example, in actual applications, when the shielding tape 100 needs to be twisted on the cable 200, the roll of the shielding tape 100 needs to be lower than the height of the cable 200 to be wound; when the shielding tape 100 needs to be reversely twisted on the cable 200, the roll of the shielding tape 100 needs to be higher than the height of the cable 200 to be wound.

[0046] As shown in FIG. 6 , the tensioning assembly 64 in this embodiment includes: a magnetic powder brake 646 mounted on the support plate 61, a first tensioning wheel 641, which is installed in cooperation with the magnetic powder brake 646, and a second tensioning wheel 642, a third tensioning wheel 643, and a fourth tensioning wheel 644 arranged in a triangle, wherein the second tensioning wheel 642, the third tensioning wheel 643, and the fourth tensioning wheel 644 are connected by a tensioning belt 645. The shielding belt 100 passes between the first tensioning wheel 641 and the tensioning belt 645, bypasses a plurality of guide wheels, and is wound around the cable 200 between the entry hole 3 and the exit hole 5. The position of the first tensioning wheel 641 is adjusted by the magnetic powder brake 646 to achieve the tensioning action of the shielding belt 100. At the same time, the reel assembly 63 in this embodiment includes a reel 631, a guide post arranged on the reel 631, a compression spring 632 sleeved on the outer side of the guide post for compressing the roll of the shielding belt 100, and a tightening nut 633 for adjusting the pressure of the compression spring 632. The tension of the shielding belt 100 is further controlled by adjusting the spring pressure. The dual control of the pressure spring and the magnetic powder brake 646 is adopted to ensure the stable operation of the tension of the shielding belt 100.

[0047] To adapt to different usage scenarios, two bag holding devices 6 are provided in this embodiment, and a photoelectric switch 7 is also installed on the support plate 61, which specifically adopts diffuse reflection optical fiber. When the shielding tape 100 is used up or broken, the diffuse reflection optical fiber has no reflection signal, and feedback is given to the system as the tape is finished or broken. The use of diffuse reflection optical fiber makes it unnecessary for the wrapping machine of this embodiment to manually monitor the shielding tape in real time, saving manpower cost investment, avoiding the insecurity caused by manual monitoring and the disadvantages of unqualified cables caused by broken or finished tapes. An optical fiber amplifier 8 for adjusting the reaction sensitivity and detection distance of the diffuse reflection optical fiber is also provided on the frame 1. The specific adjustment principle is a relatively mature technology and will not be elaborated on in detail here.

[0048] Reference Figure 1 In order to calculate the length of the wound cable 200, the present embodiment also includes a counting device 9 installed on the frame 1 corresponding to the entry end of the cable 200, which is used to calculate the length of the cable 200 entering the entry hole 3. The counting device 9 in the present embodiment is a meter wheel. Any counting device 9 available on the market can be used in the present wrapping machine. There is no absolute limitation on the structure of the counting device 9.

[0049] The utility model does not set up its own power source, but uses the single twisting machine in the subsequent process to provide twisting drag force to provide power for the twisting of the shielding tape 100 and the cable 200. It has a simple structure, stable operation, and saves cost investment. At the same time, it solves the problem of wind resistance caused by the shielding tape 100 rotating around the cable 200 in the prior art, which affects the wrapping speed.

[0050] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
