[0017] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] like Figures 1 to 8 As shown, a cable stranding machine provided in this embodiment includes a machine table 10, on which a stranding drum assembly 11, a stranding barrel assembly 12, a crimping roller assembly 13 and a winding drum assembly 14 are arranged in sequence, and also includes: a deburring assembly 15 installed on the machine table 10, the deburring assembly 15 is located between the stranding barrel assembly 12 and the crimping roller assembly 13, the deburring assembly 15 includes: an annular mounting seat 16, three deburring blocks 17 are distributed in a circular array on the inner ring of the annular mounting seat 16 and are close to the surface of the cable 18, an air inlet chamber 19 is located in the annular mounting seat 16, and an air blowing assembly 20 equal to the number of the deburring blocks 17 is arranged on the inner ring of the annular mounting seat 16 to blow the surface of the cable 18 running in the annular mounting seat 16, and the deburring blocks 17 are installed on the air blowing assembly 20.

[0020] The working principle and beneficial effects of the above technical solution are: The present invention discloses a cable twisting machine, wherein the cable to be twisted is sequentially passed through a twisting drum assembly 11, a twisting barrel assembly 12, a deburring assembly 15 and a wire pressing roller assembly 13, and is wound on a winding drum assembly 14. After the twisting drum assembly 11 and the twisting barrel assembly 12 work, a cable 18 is formed, and the cable 18 is passed through an annular mounting seat 16. The surface of the cable 18 is attached to a deburring block 17 for movement. After the deburring block 17 rubs the surface of the cable 18, the burrs are removed, and the air source sends high-pressure gas into the air inlet chamber 19, and blows the surface of the cable 18 through the air blowing assembly 20, so that the heat dissipation on the cable 18 after the twisting is completed can be accelerated. The present invention provides a cable twisting machine, wherein the deburring block 17 removes the burrs on the surface of the cable 18, and the air blowing assembly 20 accelerates the heat dissipation on the cable 18, so that when the winding drum assembly 14 completes the winding of the cable 18, the cable is evenly distributed in a roll.

[0021] In one embodiment, the deburring block 17 is arranged in a hollow arc structure, and three deburring blocks 17 are arranged to form a ring structure for the cable 18 to pass through. The air blowing assembly 20 is connected to the deburring block 17, and a gap 29 is left between adjacent deburring blocks 17 for air to escape.

[0022] The working principle and beneficial effects of the above technical solution are: The cable 18 is passed through a ring structure surrounded by three deburring blocks 17 for the cable 18 to pass through, thereby completing the removal of burrs on its surface. Because the deburring block 17 is a cavity structure, the air blowing component 20 sends air into the deburring block 17, thereby blowing the inner wall of the deburring block 17 close to the end of the cable 18, and the heat generated by the friction between the deburring block 17 and the cable 18 is sent out through the gap 29 left between adjacent deburring blocks 17. In this way, the heat generated by the friction between the deburring block 17 and the cable 18 is transferred away in time to prevent the heat from accumulating and being transferred to the cable 18.

[0023] In one embodiment, the air blowing assembly 20 includes: The air blowing chamber 21 is disposed in the annular mounting seat 16, and the inner ring end of the air blowing chamber 21 close to the annular mounting seat 16 is open; The air supply port 1 22 and the air supply port 23 are arranged on the inner wall of the air blowing chamber 21 in parallel with the center line direction of the annular mounting seat 16 and are connected to the air inlet chamber 19; The oblique air guide block 24 is integrally formed and installed on the inner wall of the air blowing chamber 21 near the end of the stranding barrel assembly 12 .

[0024] The working principle and beneficial effects of the above technical solution are: The high-pressure gas in the air inlet chamber 19 is blown into the air inlet chamber 19 from the air supply port 1 22 and the air supply port 2 23, and is blown on the surface of the cable 18 under the guidance of the inclined air guide block 24, thereby completing the front end cooling. The applicant particularly pointed out that the front end is the front end of the annular mounting seat 16, that is, the part of the cable 18 that has not penetrated the annular mounting seat 16, and this part is also the part of the formed cable 18 after the wire drum assembly 11 and the stranding barrel assembly 12 work. This part carries heat and needs to be purged and cooled in time.

[0025] In one embodiment, an air supply shell 25 is slidably installed in the air blowing chamber 21. The air supply shell 25 is open near the air blowing chamber 21 and near the inclined air guide block 24. At least the air supply port 1 22 and the air supply port 23 are purged in the air supply shell 25 away from the end of the air blowing chamber 21. The end of the air supply shell 25 away from the air blowing chamber 21 is connected to the deburring block 17 through an inclined mounting frame 26. The end of the inclined mounting frame 26 close to the deburring block 17 is inclined away from the stranding barrel assembly 12. An air supply channel 27 connected between the air supply shell 25 and the deburring block 17 is formed in the inclined mounting frame 26. An inclined air guide surface 28 for guiding the gas purged from the air supply port 23 is formed on the inclined mounting frame 26.

[0026] The working principle and beneficial effects of the above technical solution are: The high-pressure gas in the air inlet chamber 19 is blown into the air inlet chamber 19 from the air supply port 1 22 and the air supply port 2 23. Due to the setting of the air supply shell 25, the high-pressure gas in the air inlet chamber 19 is preferentially purged into the air supply shell 25 away from the end of the air blowing chamber 21. In this case, part of the gas quickly moves in the direction close to the inclined air guide block 24, and under the guidance of the inclined air guide block 24, it is blown on the surface of the cable 18, thereby completing the front end cooling, and part of the gas is quickly sent into the deburring block 17 from the air supply channel 27, thereby blowing on the inner wall of the deburring block 17 close to the cable 18 end, and the heat generated by the friction between the deburring block 17 and the cable 18 is sent out through the gap 29 between adjacent deburring blocks 17. In this way, the heat generated by the friction between the deburring block 17 and the cable 18 is transferred away in time to prevent the heat from accumulating and being transferred to the cable 18. When the heat accumulation caused by the friction between the deburring block 17 and the cable 18 is detected, the air supply housing 25 in the air blowing chamber 21 slides toward the oblique air guide block 24, so that only the air supply port 1 22 is purged on the end of the air supply housing 25 away from the air blowing chamber 21, so as to ensure that the front end is cooled and the inner wall of the deburring block 17 is close to the end of the cable 18 for cooling, and the air supply port 23 is exposed outside the air supply housing 25 and purged on the oblique air guide surface 28, so that the deburring block 17 installed on the oblique mounting frame 26 can be pressed down by high-pressure airflow, so that the deburring block 17 is close to the surface of the cable 18, and the high-pressure airflow is purged on the surface of the cable 18 under the guidance of the oblique air guide surface 28, so as to complete the cooling of the rear end. The applicant particularly pointed out that the rear end is the rear end of the annular mounting seat 16, that is, the part of the cable 18 that has passed through the annular mounting seat 16, and this part also needs to be purged and cooled in time due to the accumulation of heat generated by the friction between the deburring block 17 and the cable 18.

[0027] In one embodiment, an ionic liquid chamber 30 is installed in the deburring block 17, and the ionic liquid chamber 30 is close to the inner wall of the deburring block 17 away from the end of the oblique mounting frame 26. The ionic liquid chamber 30 stores a conductive ionic liquid, and the ionic liquid chamber 30 is also equipped with a conductive rod 1 31 and a conductive rod 2 32 extending into the ionic liquid. The conductive rod 1 31 and the conductive rod 2 32 are respectively arranged near the two ends of the deburring block 17, and two wires 33 are symmetrically installed in the oblique mounting frame 26 with the air supply channel 27 as the center, and the two wires 33 extend into the deburring block 17. , and are respectively connected to the conductive rod 1 31 and the conductive rod 2 32. A resistance sensor 34 connected to two wires 33 is installed on the inner wall of the air supply housing 25. The micro PLC controller 35 is installed on the inner wall of the air supply housing 25. The resistance sensor 34 is electrically connected to the micro PLC controller 35. A micro motor 36 electrically connected to the micro PLC controller 35 is also installed in the air blowing chamber 21. A screw 37 is installed at the output end of the micro motor 36. The screw 37 is sleeved with a screw sleeve 38 connected to the inner wall of the air supply housing 25.

[0028] The working principle and beneficial effects of the above technical solution are: The heat generated by the friction between the deburring block 17 and the cable 18 is transferred to the ion liquid chamber 30, and the ion liquid in the ion liquid chamber 30 absorbs the heat, and the high-pressure gas sent into the deburring block 17 from the air supply channel 27 is blown on the ion liquid chamber 30, so that the heat absorbed by the ion liquid is sent out through the gap 29 between adjacent deburring blocks 17 to ensure that the ion liquid chamber 30 discharges the heat in time. When the heat generated by the friction between the deburring block 17 and the cable 18 accumulates, it means that the heat is too large and cannot be sent out in time. At this time, after the ion liquid is heated, the conductive particles in it accelerate the movement, so that the conductivity of the ion liquid is also improved. In this way, the resistance of the loop formed by the conductive rod 1 31 and the conductive rod 2 32 is reduced. After the resistance sensor 34 detects the resistance reduction signal, it is transmitted to the micro PLC controller 35. After receiving the signal, the micro PLC controller 35 sends a work instruction to the micro motor 36, and the screw 37 installed on the output end of the micro motor 36 rotates, thereby driving the screw sleeve 38 sleeved on the screw sleeve 37 and the air supply shell 25 fixedly connected to the screw sleeve 38 to slide in the air blowing chamber 21 toward the inclined air guide block 24, so that the air supply port 2 23 can be exposed outside the air supply shell 25, so that the rear end cooling can be completed.

[0029] In one embodiment, the micro motor 36 is installed on the inner wall of the air blowing chamber 21 near the air delivery port 22 and is arranged near the inclined air guide block 24. The screw 37 extends into the air delivery shell 25, and the screw sleeve 38 is fixedly installed on the inner wall of the air delivery shell 25 away from the inclined air guide block 24.

[0030] In one embodiment, two ends of the deburring block 17 are provided with air outlets 39 for discharging air to the gap 29 .

[0031] The working principle and beneficial effects of the above technical solution are: The heat generated by the friction between the deburring block 17 and the cable 18 is transferred to the ionic liquid chamber 30, and the ionic liquid in the ionic liquid chamber 30 absorbs the heat, and the high-pressure gas sent into the deburring block 17 from the air supply channel 27 is blown onto the ionic liquid chamber 30, so that the heat absorbed by the ionic liquid is sent out through the air outlet 39 to ensure that the ionic liquid chamber 30 discharges the heat in time.

[0032] In one embodiment, the annular mounting seat 16 is mounted on the top of the platform 10 via a vertical rod 40 .

[0033] The beneficial effects of the above technical solution are: The vertical rod 40 is provided to facilitate mounting the annular mounting seat 16 on the machine platform 10 .

[0034] In one embodiment, the crimping roller assembly 13 includes two crimping rollers arranged vertically in parallel, with a channel for the cable 18 to pass through between the two crimping rollers. The reciprocating screw assembly is installed on the top of the machine 10, and the two crimping rollers are connected to the reciprocating screw assembly through a vertical mounting frame.

[0035] The working principle and beneficial effects of the above technical solution are: The cable 18 passes through a channel formed by two crimping rollers. While the crimping rollers crimp the cable 18 , the reciprocating screw rod assembly drives the crimping roller assembly 13 to reciprocate, thereby evenly winding the cable 18 on the winding drum assembly 14 .

[0036] This embodiment further provides a wire stranding method, which uses the above cable stranding machine, including: Step 1, the cable to be twisted passes through the twisting drum assembly 11, the twisting barrel assembly 12, the deburring assembly 15 and the crimping roller assembly 13 in sequence, and is wound on the winding drum assembly 14, the cable twisting machine works, the twisting drum assembly 11 forms the cable 18 after twisting, the twisting barrel assembly 12 guides the cable 18, the deburring assembly 15 deburrs the surface of the cable 18, the crimping roller assembly 13 presses the cable 18, and finally winds it on the winding drum assembly 14; Step 2, the cable 18 runs against the surface of the deburring block 17, the air supply port 1 22 and the air supply port 23 supply air into the air supply housing 25, part of the air flow is sent into the air blowing chamber 21, and under the guidance of the inclined air guide block 24, it is blown on the surface of the cable 18, so as to complete the front end cooling, the deburring block 17 rubs against the surface of the cable 18 to generate heat, part of the air flow is sent into the deburring block 17 through the air supply channel 27, and is discharged from the gap 29 through the air outlet 39 to take away the heat generated by the friction of the deburring block 17; Step 3, when the heat of the deburring block 17 is too high, the air supply housing 25 slides toward the direction close to the micro motor 36, the air supply port 1 22 supplies air into the air supply housing 25, and the air supply port 2 23 blows on the inclined air guide surface 28, pressing down the deburring block 17 installed on the inclined mounting frame 26, and under the guidance of the inclined air guide surface 28, blowing on the surface of the cable 18, thereby completing the cooling of the rear end.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
