Description

Technical Field

[0001] The invention belongs to the technical field of shielded cable production, and in particular relates to a full-automatic wave-proof sleeve threading device for shielded cable processing. Background Art

[0002] Shielded cables are cables covered with anti-wave sleeves (i.e. shielding nets) and are used in situations where high signal shielding effects are required. For example, in complete equipment such as filters, a large number of interconnected cables need to be shielded; for example, in the process of electromagnetic compatibility testing, shielding effectiveness enhancement and other testing and rectification processes, temporary anti-wave sleeves are often required for cables.

[0003] For pre-purchased shielded cables, the surge protector is pre-wrapped on the outside of the cable and can be used directly. However, for specific application requirements of different devices, because the cables used often include multiple strands of wires of different specifications (including wire cores and insulation layers), it is generally necessary to temporarily or on-site sheath the wires into surge protectors to form shielded cables. This process is generally called surge protector threading.

[0004] For temporary or on-site threading applications, the traditional threading method generally uses manual threading to gradually insert the wire into the wave-proof sleeve, which usually requires more than two people to cooperate with each other to complete, which is time-consuming, labor-intensive and inefficient.

A plurality of transverse support columns are installed on the wave-proof sleeve hanger. One end of the wire passes through the gap between the driving wheel and the driven wheel and then passes through the wire feeding pipe, the tapered tube, and the straight tube in sequence and is connected to the guide terminal. A gap for high-pressure gas to pass through is provided between the inner wall of the straight tube and the outer wall of the wire. The support column is close to the guide terminal, and the outer diameter of the guide terminal is larger than the diameter of the wire and not larger than the outer diameter of the straight tube.

[0012] Preferably, in order to prevent the wire from deviating from the driving wheel and the driven wheel so as to improve the reliability of pushing the wire, a limiting concave ring for limiting the wire is respectively provided in the middle of the circumferential outer wall of the driving wheel and the middle of the circumferential outer wall of the driven wheel, and the wire is simultaneously located in the corresponding limiting concave rings of the driving wheel and the driven wheel.

At the same time, the guide terminal is continuously pushed forward by high-pressure gas to improve the threading efficiency, and finally the threading function of fully automatically threading the wire into the wave-breaking sleeve is achieved, which significantly improves the threading efficiency. By adding a micro-vibration motor to the guide terminal, the wave-breaking sleeve can be expanded more smoothly during the forward movement of the guide terminal, thereby preventing the problem that the wave-breaking sleeve is difficult to expand and the guide terminal is difficult to move forward continuously.

[0024] The present invention will be further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 7 As shown, the fully automatic wave-proof sleeve threading device for shielded cable processing of the present invention is used to thread the wire 1 into the wave-proof sleeve 21, including a base 16, a driving motor (not visible in the figure because it is blocked by the driving bracket 2), a driving bracket 2, a transmission shaft 3, a driving wheel 7, a driven wheel 4, a rolling bearing 6, an air compressor 9, an air pipe 10, a wire feeding pipe 11, a wire feeding bracket 15, a cone tube 12, a guide terminal 14 and a wave-proof sleeve hanger 17, wherein the driving motor, the driving bracket 2, the air compressor 9 and the wire feeding bracket 15 are respectively mounted on the base 16, and the wave-proof sleeve hanger 17 can be mounted on the base 16 or independently mounted on the ground, and the driving wheel 7 and the driven wheel 4, which are close to each other and arranged up and down, are respectively sleeved on the middle section of the transmission shaft 3 through their own center through holes, and the two ends of the transmission shaft 3 are respectively mounted on the driving bracket 2 through rolling bearings 6, and the transmission connected to the driving wheel 7 One end of the driving shaft 3 is connected to the rotating shaft of the driving motor, and the horizontal wire feeding pipe 11 is installed on the wire feeding bracket 15. The outlet of the air compressor 9 is connected to the wire feeding pipe 11 through the air pipe 10. The large diameter end of the tapered tube 12 is connected to one end of the wire feeding pipe 11, and the small diameter end of the tapered tube 12 extends outward to form a straight tube 13 that is interconnected. A plurality of horizontal support columns 18 are installed on the wave-proof sleeve hanger 17. One end of the wire 1 passes through the gap between the driving wheel 7 and the driven wheel 4 and then passes through the wire feeding pipe 11, the tapered tube 12, and the straight tube 13 in turn and is connected to the guide terminal 14. A gap for high-pressure gas to pass through is provided between the inner wall of the straight tube 13 and the outer wall of the wire 1. The support column 18 is close to the guide terminal 14, and the outer diameter of the guide terminal 14 is larger than the diameter of the wire 1 and not larger than the outer diameter of the straight tube 13. The surface of one end of the guide terminal 14 close to the support column 18 is a conical surface or a hemispherical surface.

[0026] like Figure 1-Figure 7 As shown, the present invention also discloses the following more optimized specific structures:

[0027] In order to enable the guide terminal 14 to more smoothly penetrate into the wave-proof sleeve 21 and move forward smoothly by vibration, and to facilitate processing and assembly, the guide terminal 14 includes an outer shell, a guide end 145, a terminal 142 and a micro vibration motor 144. The micro vibration motor 144 is installed in the outer shell, and the outer shell is formed by two semicircular shells 143 connected to each other. The guide end 145 with a conical or hemispherical surface is installed at one end of the outer shell and close to the support column 18. The terminal 142 with a welding cup 141 is installed at the other end of the outer shell and is welded to the wire 1 through the welding cup 141. The switch of the micro vibration motor 144 is extended from the terminal 142 to control the start and stop of the micro vibration motor 144, while preventing the extended switch from affecting the smooth movement of the guide terminal 14.

[0028] In order to facilitate assembly, reduce volume and increase smoothness, the two semicircular shells 143, the outer shell and the guide end 145, and the outer shell and the wiring terminal 142 are respectively welded.

[0029] In order to better guide the high-pressure gas to push the guide end 14 forward, an air inlet 20 is provided on the wall of the wire feeding tube 11. The air inlet 20 is inclined 30°-60° from the outer end to the inner end toward the direction close to the cone tube 12, preferably 45°.

[0030] In order to better guide the high-pressure gas to push the guide end 14 forward, there are two air inlet holes 20 which are arranged in sequence in the axial direction of the wire feeding pipe 11 , and the outlet of the air compressor 9 is connected to the outer ends of the two air inlet holes 20 through two air pipes 10 respectively.

[0031] In order to prevent the wire from deviating from the driving wheel 7 and the driven wheel 4 so as to improve the reliability of pushing the wire 1, a limiting concave ring 5 for limiting the wire 1 is respectively provided in the middle of the circumferential outer wall of the driving wheel 7 and the middle of the circumferential outer wall of the driven wheel 4, and the wire 1 is simultaneously located in the limiting concave ring 5 of the driving wheel 7 and the limiting concave ring 5 of the driven wheel 4 which correspond to each other.

[0032] In order to facilitate binding and fixing one end of the wave-breaking sleeve 21, an annular groove 19 for binding and fixing the wave-breaking sleeve 21 is provided on the outer wall of the middle section of the straight pipe 13.

[0033] In order to achieve a more stable and reliable pushing effect on the wire 1, a driving bracket 2, two transmission shafts 3, a driving wheel 7, a driven wheel 4 and four rolling bearings 6 together constitute a driving assembly, and the three driving assemblies are installed on the base 16 in sequence. The rotating shaft of the driving motor is connected to the transmission shaft 3 corresponding to one of the driving assemblies, and a pulley (not marked in the figure) is installed on the transmission shaft 3 connected to the driving wheel 7. Two adjacent pulleys are connected by a belt 8, and the wire 1 passes through the three driving assemblies in sequence.

[0034] Combination Figure 1-Figure 7 When in use, first place the wave-breaking sleeve 21 on multiple support columns 18, manually insert the guide terminal 14 into one end of the wave-breaking sleeve 21, and pull and sleeve the end of the wave-breaking sleeve 21 outside the straight pipe 13, and use a strap to tie the part of the wave-breaking sleeve 21 close to the end in the annular groove 19, so as to achieve the purpose of fixing one end of the wave-breaking sleeve 21 on the straight pipe 13; then turn on the drive motor, air compressor 9 and micro vibration motor 144, the driving wheel 7 starts to rotate, and uses friction to push the wire 1 in the direction close to the guide terminal 14, and the driven wheel 4 rotates with it, and together with the driving wheel 7, ensures that sufficient friction is applied to the wire 1; at the same time, the air compressor 9 generates high-pressure gas, which passes through the air pipe 10, the wire feeding pipe 11, the cone pipe 1 in turn. 2. The straight tube 13 and part of the wave-breaking sleeve 21 generate a forward thrust for the guide terminal 14. When the high-pressure gas passes through the tapered tube 12, the pressure is increased due to the reduction in cross-section, which is conducive to pushing the guide terminal 14. The guide terminal 14 expands and moves forward in the wave-breaking sleeve 21, so that the wire 1 continues to move forward in the wave-breaking sleeve 21; the guide terminal 14 and the wire 1 continue to move forward and are supported by the support column 18 to avoid the bending of the wire 1 affecting the smooth threading; until the wire 1 is completely inserted into the wave-breaking sleeve 21, the drive motor, air compressor 9 and micro vibration motor 144 are turned off, the wave-breaking sleeve 21 is removed from the straight tube 13, the guide terminal 4 is separated from the wire 1, and the wave-breaking sleeve 21 shrinks and covers the outside of the wire 1 under its own elasticity to obtain a shielded cable.

[0035] Generally, when threading is performed using the present invention, the length of the wire 1 to be threaded is between 1 and 3 meters, which is not very long. Therefore, although the high-pressure gas will leak in the wave-proof sleeve 21, there is still a certain airflow to push the guide terminal 14. In addition, the driving force of the active wheel 7 on the wire 1 and the vibration of the micro-vibration motor 144 can enable the guide terminal 14 to smoothly expand the wave-proof sleeve 21 and move forward. The present invention is not suitable for threading operations with a length that is too long (such as more than 5 meters), because when the length is too long, it is difficult for the high-pressure gas to reach the guide terminal 14, and the thrust loss of the active wheel 7 will also be greater, which will affect the normal threading function.

[0036] The above embodiments are only preferred embodiments of the present invention and are not limitations of the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.
