[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0033] Example: Reference Figures 1-11 A cable stranding device includes a stranding mechanism for winding strand 117 around the outside of cable 125. The stranding mechanism includes a base plate 101, and is provided with a clamping mechanism for pressing strand 117 onto cable 125 and a grinding mechanism for grinding strand 117.

[0034] The stranding mechanism includes a winding frame 126 fixedly installed on a base plate 101, a winding disc 102 rotatably installed on the winding frame 126, a sleeve 114 and a connecting post 109 fixedly installed on the winding disc 102, a plurality of sliders 104 slidably installed on the winding disc 102, and a guide ring 105 rotatably installed on the sliders 104.

[0035] like Figures 2-6 As shown, the stranding mechanism also includes an internally threaded cylinder 108 fixedly mounted on the slider 104. The internally threaded cylinder 108 has an internal thread. Several adjusting screws 107 are rotatably mounted on the winding disc 102. The adjusting screws 107 and the internally threaded cylinder 108 form a threaded transmission. An internal gear ring 106 is rotatably mounted on the base plate 101. A motor frame 127 is fixedly mounted on the connecting column 109. An adjusting motor 128 is fixedly mounted on the motor frame 127. The adjusting motor 128 drives the internal gear ring 106 to rotate through gear transmission. The internal gear ring 106 drives several adjusting screws 107 to rotate synchronously through gear transmission.

[0036] like Figures 2-6As shown, a motor 112 is fixedly mounted on the base plate 101, and an output shaft 113 is fixedly mounted on the motor shaft of the motor 112. Several disc teeth 103 are provided on the winding disc 102. A fixed frame 110 is fixedly mounted on the base plate 101, and a follower disc 111 is rotatably mounted on the fixed frame 110. Several rotating teeth 118 are provided on the follower disc 111. The output shaft 113 is driven to rotate synchronously with the follower disc 111 and the winding disc 102 through gear transmission.

[0037] like Figures 2-6 As shown, several stranding frames 115 are mounted on the turntable 111 as it rotates, and a drum frame 119 is fixedly mounted on the turntable 111.

[0038] like Figures 2-6 As shown, both the drum frame 119 and the stranding frame 115 are equipped with disassembly modules. Each disassembly module includes a locking plate 124 slidably mounted on the drum frame 119 and the stranding frame 115. A disassembly screw 123 is rotatably mounted on the locking plate 124. Threaded holes are provided on the drum frame 119 and the stranding frame 115, and the disassembly screw 123 engages with these holes. A rotating pin 121 is inserted into the drum frame 119 and the stranding frame 115, and a convex ball 122 is slidably mounted on the rotating pin 121. Each part is provided with a groove that matches the convex ball 122. A spring is provided between the convex ball 122 and the rotating pin 121. In use, the convex ball 122 is inserted into the hole of the rotating pin 121 and the stranding frame 115. The cable drum 120 is rotatably mounted on the rotating pin 121 in the drum frame 119. The stranded wire drum 116 is rotatably mounted on the rotating pin 121 in the stranding frame 115. The clamping plate 124 is located outside the rotating pin 121. The stranded wire 117 is wound on the stranded wire drum 116 and the cable 125 is wound on the cable drum 120.

[0039] In use, cable 125 is pulled out from cable reel 120, passes through sleeve 114, then passes between stranding frame 204 and stranding block 205, then passes between two inclined pressure rollers 208, and is fixedly mounted on external winding device. Then, stranded wire 117 is pulled out from stranding reel 116, passes between two burr rollers 303, then passes through guide ring 105, and then passes between stranding frame 204 and stranding block 205. The stranded wire 117 is wound around the outside of the cable 125. The motor 112 rotates, driving the output shaft 113 to rotate. The output shaft 113 drives the winding disc 102 and the disc teeth 103 to rotate through gear transmission, thereby driving the guide ring 105 to rotate. At the same time, the guide ring 105 drives the processing ring 302 to rotate synchronously through the sleeve 114. The cable 125 is wound up by the external winding device. With the rotation of the winding disc 102 and the rotating disc 111, the stranded wire 117 is evenly wound around the outside of the cable 125 for stranding.

[0040] The adjustment motor 128 can rotate by driving the internal gear ring 106 through gear transmission, which in turn drives the adjusting screw 107 to rotate, thereby causing the internal threaded cylinder 108 and the slider 104 to slide inside and outside the winding disc 102, thereby adjusting the position of the guide ring 105, and thus adjusting the angle and tightness of the stranded wire 117 wrapped around the cable 125.

[0041] When it is necessary to insert or remove the cable reel 120, the disassembly module needs to be opened. First, remove the disassembly screw 123 from the reel holder 119, and then pull out the retaining plate 124 so that the retaining plate 124 is away from the outside of the reel holder 119. At this time, the rotating pin 121 can be pulled out from the reel holder 119. At this time, the spring between the convex ball 122 and the rotating pin 121 is compressed, and then the convex ball 122 leaves the reel holder 119. Then the spring between the convex ball 122 and the rotating pin 121 rebounds, and the cable reel 120 can be removed. After inserting a new cable reel 120, insert the rotating pin 121 into the reel holder 119, and the convex ball 122 is re-engaged into the groove of the reel holder 119. Then slide the retaining plate 124 to the outside of the rotating pin 121 and fix the retaining plate 124 to the reel holder 119 with the disassembly screw 123. The disassembly and assembly are convenient.

[0042] like Figure 7 , Figure 8 As shown, the clamping mechanism includes a twisting frame 204 fixedly installed on the base plate 101, a twisting block 205 fixedly installed on the twisting frame 204 by bolts, a clamping frame 201 fixedly installed on the base plate 101, a clamping motor 202 fixedly installed on the clamping frame 201, an inner rotating ring 203 rotatably installed inside the clamping frame 201, and the clamping motor 202 drives the inner rotating ring 203 to rotate via belt drive.

[0043] like Figure 7 , Figure 8 As shown, two sets of wire pressing modules are provided inside the inner rotating ring 203. The wire pressing module includes an outer sleeve 206 fixedly installed inside the inner rotating ring 203. An inner slide rod 207 is slidably installed inside the outer sleeve 206. An inner spring 209 is provided between the inner slide rod 207 and the outer sleeve 206. An inclined pressure wheel 208 is rotatably installed on the inner slide rod 207. The inclined pressure wheel 208 forms a 45-degree angle with the cable 125.

[0044] When the external winding device pulls the cable 125 and stranded wire 117 through the stranding block 205 and the inner slide bar 207, the stranding block 205 and the inner slide bar 207 perform the first clamping of the stranded wire 117 and cable 125. The clamping motor 202 drives the inner rotating ring 203 to rotate through the belt drive. The rotation of the inner rotating ring 203 drives the outer sleeve 206, the inner slide bar 207 and the inclined pressure wheel 208 to rotate. The inclined pressure wheel 208 is clamped to the outside of the stranded wire 117 by the inner spring 209. The inclined pressure wheel 208 clamps the stranded wire 117 to the cable 125 for the second time.

[0045] like Figures 9-11 As shown, the grinding mechanism includes a processing frame 301 fixedly installed on the base plate 101, a processing ring 302 rotatably installed inside the processing frame 301, the processing ring 302 being fixedly installed with the sleeve 114, the connecting column 109 being fixedly installed with the processing ring 302, and a fixing gear ring 304 being fixedly installed on the processing frame 301.

[0046] like Figures 9-11 As shown, several small turntables 305 are rotatably mounted on the processing ring 302. A guide frame 307 is fixedly mounted on the small turntables 305. Two slides 309 are slidably mounted on the guide frame 307. A tensioning spring 308 is provided between the two slides 309. A burr wheel 303 is rotatably mounted on the slide 309. A self-rotating gear 306 is fixedly mounted on the small turntables 305. The self-rotating gear 306 meshes with the fixed gear ring 304.

[0047] like Figures 9-11 As shown, when the stranded wire 117 passes between the burr wheels 303, the burr wheels 303 are pressed against the stranded wire 117 by the tightening spring 308. When the stranded wire 117 is pulled, the surface of the stranded wire 117 is polished by the burr wheels 303 to remove rust and oxide layer. The rotation of the treatment ring 302 will drive several small turntables 305 to rotate together. Under the action of the fixed gear ring 304, the self-rotating gear 306 and the small turntables 305 rotate, so that the burr wheels 303 can fully polish the surface of the stranded wire 117.

[0048] like Figures 1-11 As shown, a cable stranding method is characterized by the following steps: Step 1: Pull out the cable 125 and fix it on the external winding device; Step 2: Pull out the stranded wire 117 and polish it; Step 3: Wrap the stranded wire 117 around the outside of the cable 125; Step 4: Press the stranded wire 117 onto the cable 125 for the first time; Step 5: Press the stranded wire 117 onto the cable 125 for the second time.

[0049] The working principle of the cable stranding device disclosed in this invention is as follows: During use, cable 125 is pulled out from cable drum 120, passes through sleeve 114, then passes between stranding frame 204 and stranding block 205, and then between two inclined pressure rollers 208. Cable 125 is then fixedly mounted on an external winding device. Stranded wire 117 is pulled out from stranding drum 116, passes between two burr rollers 303, then passes through guide ring 105, and then between stranding frame 204 and stranding block 205, winding around the outside of cable 125. Motor 112 rotates, driving output shaft 113 to rotate. Output shaft 113, through gear transmission, drives winding disc 102 and disc teeth 103 to rotate, thereby driving guide ring 105 to rotate. Simultaneously, the guide ring 105 drives the processing ring 302 to rotate synchronously through the sleeve 114, and the cable 125 is wound up by the external winding device. With the rotation of the winding disc 102 and the follow-up turntable 111, the stranded wire 117 is evenly wound around the outside of the cable 125 for stranding. When the stranded wire 117 passes between the burr wheels 303, the tightening spring 308 makes the burr wheels 303 stick to the stranded wire 117. When the stranded wire 117 is pulled, the burr wheels 303 polish the surface of the stranded wire 117 to remove rust and oxide layer. The rotation of the processing ring 302 will drive several small turntables 305 to rotate together. Under the action of the fixed gear ring 304, the self-rotating gear 306 and the small turntables 305 rotate, so that the burr wheels 303 polish the surface of the stranded wire 117. In use, cable 125 is pulled out from cable reel 120, passes through sleeve 114, then passes between stranding frame 204 and stranding block 205, then passes between two inclined pressure rollers 208, and is fixedly mounted on external winding device. Then, stranded wire 117 is pulled out from stranding reel 116, passes between two burr rollers 303, then passes through guide ring 105, and then passes between stranding frame 204 and stranding block 205. The stranded wire 117 is wound around the outside of the cable 125. The motor 112 rotates, driving the output shaft 113 to rotate. The output shaft 113 drives the winding disc 102 and the disc teeth 103 to rotate through gear transmission, thereby driving the guide ring 105 to rotate. At the same time, the guide ring 105 drives the processing ring 302 to rotate synchronously through the sleeve 114. The cable 125 is wound up by the external winding device. With the rotation of the winding disc 102 and the rotating disc 111, the stranded wire 117 is evenly wound around the outside of the cable 125 for stranding.
