Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and more particularly to a plastic extruder for cable processing. Background Art

[0002] Cable extrusion is a production process for wires and cables. It uses a screw of a specific shape to rotate in a heated barrel to squeeze the plastic sent from the hopper forward, causing the plastic to be evenly plasticized (i.e. melted). The plastic is then extruded into continuous materials of various shapes through a die head and molds of different shapes, which are then extruded onto the wire core and cable to form an insulation layer or sheath.

[0003] During the extrusion process, the plastic is formed in the extruder. This is a complex physical process, including mixing, crushing, melting, plasticizing, exhausting, compacting and finally shaping. The extrusion process includes insulation production and sheath production processes. The insulation production methods include coating, wrapping, extrusion, and their combination. After the cable is processed, it needs to be tested and corrected through various methods to ensure the quality and performance of the cable. The specific test methods and correction measures will vary according to the type, specification and production requirements of the cable. During the cable processing process, the eccentricity problem that occurs during the cable extrusion process needs to be tested. In the prior art, when eccentricity occurs in a cable after extrusion, an eccentricity tester is usually used to detect the degree of eccentricity of the cable, especially when the eccentricity of the cable is small. However, when the eccentricity is large, timely adjustment is required when the cable is still hot or soft. If the eccentricity tester is used for detection, the cable has basically cooled down at this time, and it is difficult to adjust it in time, so the cable needs to be reprocessed. Summary of the Invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a plastic extruder for cable processing.

[0005] To solve the above problems, the present invention adopts the following technical solution, which can realize real-time detection of cable eccentricity during the cable extrusion process, and timely adjust the machine body through the console when a large eccentricity of the cable is detected.

[0010] Furthermore, a transfer cavity is provided on the upper side of the fixing seat, the top end of the conduit is connected to the transfer cavity, a cover plate is hinged on the upper side of the interior of the transfer cavity, and the upper front side of the cover plate is in an inverted "L" shape.

[0011] Furthermore, a measuring component is provided inside the fixing seat, and the measuring component includes a movable cavity opened on the front side of the upper end of the fixing seat.

[0012] Furthermore, the movable cavity is located in front of the transfer cavity, and a movable plate is slidably connected to the interior of the storage cavity. The left and right sides of the lower end of the movable plate are fixedly connected to the airbags, and a column is fixedly connected to the center of the lower end of the movable plate. The lower side of the column is in extrusion contact with the lower side of the interior of the storage cavity.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 8 A plastic extruder for cable processing includes a body 1 and a water storage chamber opened at the upper end of the body 1. A control console 12 is provided on the back of the body 1. A detection component 2 is provided inside the water storage chamber 11. The detection component 2 includes a fixed seat 21 fixedly connected to the right side of the water storage chamber 11, and a wire cavity 22 is opened inside the fixed seat 21, and a movable groove 23 is opened on the upper and lower sides of the wire cavity 22. The interior of the movable groove 23 is slidably connected to a limit rod 24, and the end of the limit rod 24 close to the wire cavity 22 is fixedly connected to an extrusion block 25, and the extrusion block 25 is inserted into the movable groove 23. A pressure spring 26 is fixedly connected between the side of the movable groove 23 away from the wire cavity 22 and the limit rod 24, and the other end of the limit rod 24 is fixedly connected to a piston rod 271. A piston cavity 272 is opened on the side of the movable groove 23 close to the pressure spring 26, and the piston rod 271 is slidably connected to the inside of the piston cavity 272, and pressure sensors 273 are provided on the opposite surfaces of the upper and lower corresponding piston cavities 272.

[0023] The upper and lower sides of the center of the wire cavity 22 are both arc-shaped. After the extrusion block 25 moves, it enters the wire cavity 22. The opposite surfaces of the upper and lower corresponding extrusion blocks 25 are both arc-shaped. The wire cavity 22, the movable groove 23 and the piston cavity 272 are connected.

[0024] By adopting the above technical solution, when the machine body 1 is extruding the insulating sleeve on the outside of the copper core, the extruded cable will be transported to the water storage chamber 11 in front of the console 12. During this process, the cable will first pass through the fixed seat 21 and dock with the wire cavity 22. At this time, the extrusion block 25 in the movable groove 23 enters the wire cavity 22 from the movable groove 23 due to the compression of the limit rod 24 by the pressure spring 26, and the cable passing through the guide cavity will pass between the two extrusion blocks 25, so that the two extrusion blocks 25 close to each other will press the outside of the cable. Since the range of movement of the limit rod 24 in the movable groove 23 is limited, the degree of extrusion of the insulation layer on the outside of the copper core by the extrusion block 25 is limited. If the eccentricity of the wire is too large, it means that the copper core is not centered, but biased to one side of the insulation layer, which will cause the insulation layer to be thinner in some places. As the extrusion block 25 squeezes the cable, the copper core material is harder, so the extrusion After the block 25 squeezes both sides of the cable, the movement distance of the extrusion block 25 close to the copper core side is different from that of the other extrusion block 25. At the same time, the piston rod 271 at the other end of the limit rod 24 moves inside the piston chamber 272 under the drive of the limit rod 24 and compresses the air inside the piston chamber 272, so that the compressed air will squeeze the pressure sensor 273. If the two piston rods 271 move different distances, the pressure generated by the compressed air on the pressure sensor 273 will also be different. Finally, the pressure sensor 273 transmits the signal to the console 12, and the console 12 will adjust the body 1. Since the eccentricity of the cable can be detected in real time after the insulating sleeve is extruded, the quality of the cable can be effectively avoided from being affected by the eccentricity of the copper core during the extrusion process, and when a large eccentricity of the cable is detected, the body 1 is adjusted in time through the console 12, thereby ensuring the quality of the cable after extrusion.

[0025] like Figure 4 and Figure 5 As shown, a marking assembly 28 is provided inside the fixing seat 21 , and the marking assembly 28 includes a nozzle 281 provided on the front side of the wire cavity 22 .

[0026] A extraction member 282 is provided at the front end of the nozzle 281, and a storage chamber 283 is opened on the front side of the interior of the fixing seat 21. The front end of the extraction member 282 extends into the interior of the storage chamber 283, and a conduit 284 is inserted into the upper side of the interior of the storage chamber 283.

[0027] A transfer cavity 285 is provided on the upper side of the fixing seat 21 , and the top end of the conduit 284 is connected to the transfer cavity 285 . A cover plate 286 is hinged on the upper side of the interior of the transfer cavity 285 , and the upper front side of the cover plate 286 is in an inverted "L" shape.

[0028] By adopting the above technical solution, as the pressure sensor 273 transmits the signal to the console 12, the console 12 will also control the extraction member 282 to extract the paint from the inside of the storage chamber 283, and then spray the paint onto the cable through the nozzle 281. When the paint needs to be poured into the storage chamber 283, the cover 286 can be opened from the upper side of the transfer chamber 285, and then the paint is poured into the transfer chamber 285. The paint entering the transfer chamber 285 is finally sent to the storage chamber 283 from the conduit 284. When it is detected that the cable is eccentric after extrusion, the nozzle 281 can spray paint to mark the outside of the cable, so that the staff can quickly find the direction where the cable is eccentric after the cable processing is completed, thereby ensuring the quality of the cable after processing.

[0029] like Figures 3 to 6 As shown, a measuring assembly 29 is provided inside the fixing base 21 , and the measuring assembly 29 includes a moving cavity 291 opened on the front side of the upper end of the fixing base 21 .

[0030] The movable cavity 291 is located in front of the transfer cavity 285. The interior of the storage cavity 283 is slidably connected to a movable plate 292. The left and right sides of the lower end of the movable plate 292 are fixedly connected to the airbag 293. The center of the lower end of the movable plate 292 is fixedly connected to a column 294. The lower side of the column 294 is in squeeze contact with the inner lower side of the storage cavity 283.

[0031] A fixed rod 295 is fixedly connected to the upper side of the movable plate 292, and the fixed rod 295 is slidably connected in the movable cavity 291. A notch 296 is provided on the back side of the movable plate 292, and the movable plate 292 is wrapped around the outside of the conduit 284 through the notch 296. An embedding groove 297 is provided inside the movable cavity 291.

[0032] By adopting the above technical solution, after the pigment is sent into the storage chamber 283 through the conduit 284, the movable plate 292 inside the storage chamber 283 is supported by the column 294, and the conduit 284 passes through the movable plate 292 through the notch 296 on the back side of the movable plate 292, so that the pigment transported by the conduit 284 is always under the movable plate 292. At the same time, as the amount of pigment under the movable plate 292 increases, the pigment will gradually lift the air bag 293 under the movable plate 292, so that the movable plate 292 is always above the pigment according to the buoyancy of the air bag 293 and is never in contact with the pigment. In the process of the movable plate 292 moving upward, the fixed rod 295 fixed above the movable plate 292 and inserted into the movable chamber 291 will Sliding inside the movable chamber 291, when the top of the fixed rod 295 moves to the same level as the top of the movable chamber 291, the pigment stops being poured into the transfer chamber 285, and then the cover 286 is closed. As the amount of pigment inside the storage chamber 283 gradually decreases, the movable plate 292 will also drop synchronously due to the drop in the liquid level of the pigment until the top of the fixed rod 295 is flush with the position of the embedded chamber, and the movable plate 292 and the fixed rod 295 stop moving downward. Since the amount of pigment inside the storage chamber 283 can be visually displayed by the position of the top of the fixed rod 295 inside the movable chamber 291, the staff can judge whether it is necessary to continue pouring pigment into the transfer chamber 285 by the movement of the fixed rod 295 when injecting pigment, so as to control the supply amount of pigment.

[0033] like Figures 4 to 8 As shown, a warning component 3 is provided inside the fixing seat 21 , and the warning component 3 includes a laser rangefinder 31 arranged inside the embedding groove 297 .

[0034] Warning lights 32 are arranged in parallel at the center of the upper end of the fixing base 21 . The warning lights 32 and the laser rangefinder 31 are both electrically connected to an external power supply.

[0035] By adopting the above technical solution, as the piston rod 271 compresses the air inside the piston chamber 272, the pressure generated by the compressed air will be transmitted to the pressure sensor 273 inside the piston chamber 272. The pressure sensor 273 then transmits the information to the console 12, causing the console 12 to control one of the warning lights 32 above the fixing seat 21 to light up. After the fixing rod 295 moves to the position of the embedded groove 297, the laser light originally irradiated by the laser rangefinder 31 on the outside of the fixing rod 295 will be irradiated on the inner wall of the embedded groove 297. After the laser rangefinder 31 transmits the signal to the console 12, the console 12 will control another warning light 32 above the fixing seat 21 to light up. Since the warning light 32 can light up after detecting eccentricity of the copper core inside the cable, it can achieve the purpose of warning the staff. At the same time, when the paint inside the storage chamber 283 is used up, the other warning light 32 will also light up. At this time, the staff can supply paint in time according to the prompt of the warning light 32 to ensure the marking effect of the cable.

[0036] Working principle: After the cable enters the fixing seat 21 and docks with the wire cavity 22, the pressure spring 26 always squeezes the limit rod 24, so that the limit rod 24 enters the wire cavity 22 from the moving groove 23 and presses the outside of the cable at the same time. If the copper core is eccentric, the range of movement of the limit rod 24 in the moving groove 23 is limited, and the copper core is hard, so that after the extrusion block 25 squeezes both sides of the cable, the extrusion block 25 close to the copper core side and the other extrusion block 25 move a different distance. At the same time, the piston rod 271 at the other end of the limit rod 24 moves inside the piston cavity 272 under the drive of the limit rod 24 and compresses the air inside the piston cavity 272, so that The compressed air will squeeze the pressure sensor 273. If the two piston rods 271 move different distances, the pressure generated by the compressed air on the pressure sensor 273 will also be different. Finally, the pressure sensor 273 transmits a signal to the console 12, and the console 12 adjusts the body 1. At the same time, the console 12 controls one of the warning lights 32 above the fixing seat 21 to light up. As the pressure sensor 273 transmits a signal to the console 12, the console 12 also controls the extraction member 282 to extract the pigment from the storage chamber 283, and then sprays the pigment to the cable through the nozzle 281. When the pigment needs to be poured into the storage chamber 283, the cover 2 can be opened. 86 is opened from the upper side of the transfer chamber 285, and then the pigment is poured into the transfer chamber 285, and finally sent to the storage chamber 283 from the conduit 284. Because the conduit 284 passes through the movable plate 292 through the notch 296 on the back of the movable plate 292, the pigment transported by the conduit 284 is always under the movable plate 292. At the same time, as the amount of pigment under the movable plate 292 increases, the pigment will gradually lift the air bag 293 under the movable plate 292, so that the movable plate 292 is always above the pigment due to the buoyancy of the air bag 293 and never contacts the pigment. In the process of the movable plate 292 moving upward, the movable plate 292 is fixed above the movable plate 292 and inserted into the movable chamber 29 The fixed rod 295 inside the movable chamber 291 will slide. When the top of the fixed rod 295 moves to the same level as the top of the movable chamber 291, the pigment stops pouring into the transfer chamber 285. As the amount of pigment in the storage chamber 283 gradually decreases, the movable plate 292 will also drop synchronously due to the drop in the pigment level. After the fixed rod 295 moves to the position of the embedded groove 297, the laser rangefinder 31, which originally irradiated the outside of the fixed rod 295, will irradiate the inner wall of the embedded groove 297. After the laser rangefinder 31 transmits a signal to the control console 12, the control console 12 will control another warning light 32 above the fixed base 21 to light up, and the pigment supply will stop at this time.
