Detailed implementation manners

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] The wire core of the present invention is a kind of electrical accessory in the intelligent power grid industry, which is a wire for transmitting electricity or information from one place to another. The wire and cable extrusion molding machine is a part of the equipment for manufacturing a covering layer on the outer side of the wire core, and is used to manufacture the insulation layer and outer sheath of various wires and cables.

[0048] Embodiment 1

[0049] Refer to the attached drawings of the specification Figures 1 - 3 and Figures 6 - 7, the present invention provides an extrusion molding machine for wire and cable, including a frame 1, on the top of which a main machine part 2 is fixedly installed. Among them, the main machine part 2 is composed of a hopper, a feeding screw, and a heating cylinder, and is used to melt the material to be melted and convey it to a designated station. A machine head 4 is arranged at the discharging end of the main machine part 2, and a fastening part 3 is arranged between the main machine part 2 and the machine head 4 for buckling and installing between the discharging end of the main machine part 2 and the feeding end of the machine head 4. The machine head 4 is composed of a pre-treatment mechanism 42, a coating mechanism 41, and a post-treatment mechanism 43 arranged vertically in sequence, and both the pre-treatment mechanism 42 and the post-treatment mechanism 43 are detachably installed with the coating mechanism 41;

[0050] The pre-treatment mechanism 42 is used for pre-treating the surface of the core of the cable to be formed, the coating mechanism 41 is used to coat the molten material supplied by the main machine part 2 on the surface of the cleaned core, and prevent local coking of the molten material in the coating area, and the post-treatment mechanism 43 is used for cooling and shaping the extruded cable.

[0051] It should be noted that in the present invention, by adopting a detachable installation structure design between the machine head 4 and the main machine part 2, as well as between the pre-treatment mechanism 42, the coating mechanism 41, and the post-treatment mechanism 43 that make up the machine head 4, it is convenient to disassemble, replace, and maintain and operate each component. At the same time, by adopting a vertical installation design for the pre-treatment mechanism 42, the coating mechanism 41, and the post-treatment mechanism 43 that make up the machine head 4, the longitudinal space of the extrusion molding machine can be fully utilized, and the floor area in the horizontal direction can be saved.

[0052] Specifically, as Figures 6 - 9 shown, the coating mechanism 41 includes a coating cylinder 411, three L-shaped support rods 412 evenly distributed in a ring are fixedly arranged on the outer side of the coating cylinder 411, a ring platform 413 and a seat block 414 are fixedly sleeved on the outer side of each L-shaped support rod 412, and the bottom end of each L-shaped support rod 412 movably penetrates through the frame 1. A notch 4117 is opened in the middle of the outer side of each seat block 414, and a stirring assembly is arranged between the seat block 414 and the coating cylinder 411 for stirring the molten material entering the inside of the coating cylinder 411;

[0053] The stirring assembly includes a groove 415 with an arc-shaped structure formed at the inner bottom end of the material covering cylinder 411. A vertical rod 416 is movably penetrated through the position of the material covering cylinder 411 corresponding to the groove 415 at the bottom end. Both ends of the vertical rod 416 are fixedly connected with a mold block 417 and a hemispherical block 4110 respectively. Among them, the upper and lower end faces of the mold block 417 are both convex arc-shaped structures, and the arc-shaped structure at the bottom of the mold block 417 is adapted to the groove 415. And, a plurality of such mold blocks 417 are provided and are evenly distributed in a ring centered on the vertical central axis of the material covering cylinder 411. One end of the vertical rod 416 located outside the material covering cylinder 411 is rotatably installed with a ring plate 4111 through a bearing. The movable installation mode of this ring plate 4111 can ensure that the existence of the first spring 4112 does not affect the rotation of the corresponding vertical rod 416. A first spring 4112 that fixedly connects the ring plate 4111 and the material covering cylinder 411 is sleeved outside the vertical rod 416. Among them, when the mold block 417 is fitted inside the corresponding groove 415 at one end, the corresponding first spring 4112 is still in a compressed state;

[0054] The stirring assembly further includes a first ring cylinder 418 arranged between the three seat blocks 414. Two limiting rings 419 are fixedly sleeved outside the first ring cylinder 418. The seat blocks 414 are located between the two limiting rings 419, and the opposite sides of the two limiting rings 419 are respectively in contact with the upper and lower end faces of the seat blocks 414. The hemispherical block 4110 is located inside the first ring cylinder 418. An internal gear ring 4115 and an external gear ring 4116 are respectively fixedly arranged on the inner and outer sides of the first ring cylinder 418;

[0055] Tooth grooves meshing with the internal gear ring 4115 are formed on the outside of the hemispherical block 4110. A gear disk meshing with the external gear ring 4116 is rotatably installed inside the notch 4117 on one of the seat blocks 414. The gear disk is driven by a motor to rotate. A support base 4113 is also fixedly arranged on the inner side of the first ring cylinder 418. An arc block 4114 for jacking up the hemispherical block 4110 upward is fixedly arranged on the top of the support base 4113. Among them, a plurality of support bases 4113 installed with the arc block 4114 are provided and are evenly distributed in a ring, which can effectively shorten the time interval for the same hemispherical block 4110 to be jacked up again and improve the stirring rate of the molten material entering the material covering cylinder 411.

[0056] It should be noted that in the process of feeding the molten material into the coating barrel 411 to coat the wire core passing through the coating barrel 411, after the molten material enters the coating barrel 411, the gear disc is driven to rotate by a motor, and the rotating gear disc is used to drive the outer gear ring 4116 to rotate, thereby driving the ring barrel 418 to rotate. In the process of continuous rotation of the ring barrel 418, due to the meshing between the tooth grooves on the hemispherical block 4110 and the inner gear ring 4115, the continuously rotating ring barrel 418 will synchronously drive the multiple hemispherical blocks 4110 to rotate synchronously, and drive the mold block 417 located inside the coating barrel 411 to continuously rotate. Rotate. At the same time, during the continuous rotation of the ring cylinder 418, the arc block 4114 will also move synchronously with the ring cylinder 418 along with the bracket 4113. After the rotating arc block 4114 comes into contact with the hemispherical block 4110, as the ring cylinder 418 continues to rotate, the synchronously rotating arc block 4114 will gradually push up the corresponding hemispherical block 4110 and compress the spring 1 4112 at the corresponding position. When the lifted hemispherical block 4110 completely passes over the arc block 4114 at the position, the corresponding hemispherical block 4110 will instantly reset under the restoring force of the spring 1 4112, waiting for the next round of pushing up.

[0057] The design of the stirring assembly can not only stir the molten material inside the covering barrel 411 in the horizontal direction, but also simultaneously flip it in the vertical direction, thereby ensuring that the molten material inside the covering barrel 411 is always in a flowing state, avoiding local coking and waste.

[0058] Specifically, Figure 8 As shown, the bottom end of each L-shaped support rod 412 is fixedly connected to a rope 8, and the end of each rope 8 is fixedly connected to a pin rod 7. A rod groove is penetrated through the outer side of one end of each L-shaped support rod 412 that passes through the frame 1, and the pin rod 7 is movably inserted into the corresponding rod groove. A nut 6 is threadedly sleeved on the outer side of one end of each L-shaped support rod 412 that passes through the frame 1, wherein after the pin rod 7 is inserted into the corresponding rod groove, the pin rod 7 will not automatically separate from the rod groove without the action of external force. At the same time, an external thread is tapped on the outer side of one end of the L-shaped support rod 412 that passes through the frame 1, which is used to cooperate with the nut to detachably and fix the covering barrel 411 on the top of the frame 1.

[0059] It should be noted that in the process of docking and installing the head part 4 and the main body part 2, the L-shaped support rod 412 is inserted into the top of the frame 1, and the nut 6 is used to cooperate with the corresponding ring stage 413 to fix the covering barrel 411 on the frame 1. The installation is convenient and quick. At the same time, the feed port of the covering barrel 411 is directly opposite to the discharge port of the main body part 2, and then the fastening part is used to dock the head part 4 and the main body part 2 to achieve sealing of the docking area between the two to prevent leakage during the feeding process.

[0060] Specifically, as Figures 6 - 7 and Figures 10 - 12 shown, the pre-treatment mechanism 42 includes a lower mounting plate 421 fixedly installed at the bottom of the covering cylinder 411 through a locking bolt. A first column 422 is fixedly provided at the bottom of the lower mounting plate 421. The bottom end of the first column 422 is fixedly connected to a treatment cylinder 423. Two isolation rings 424 are fixedly provided inside the treatment cylinder 423. An annular water-absorbing cotton block 4210 is installed between the two isolation rings 424. A first water receiving tray 428 is fixedly sleeved outside the treatment cylinder 423. Two groups of through slots 427 are formed through the outer side of the treatment cylinder 423 corresponding to the position of the first water receiving tray 428. Among them, the two groups of through slots 427 are respectively arranged on the upper and lower sides of the lower isolation ring 424, and the through slots 427 on both sides of the isolation ring 424 are flared from the outside to the inside;

[0061] The two isolation rings 424 divide the treatment cylinder 423 into a surface treatment area, a water absorption area, and a surface cleaning area arranged in sequence from top to bottom. A plasma treatment device 425, a water squeezing assembly 429, and a first ultrasonic vibrating plate 426 are respectively provided at the positions of the treatment cylinder 423 corresponding to the surface treatment area, the water absorption area, and the surface cleaning area. Among them, the plasma treatment device 425 uses a plasma generator to generate an electric field, ionize a process gas (generally argon) to produce plasma, and use these plasmas to etch the surface of the wire core to increase the surface roughness of the wire core, improve the adhesion of the coating material, and enhance the compatibility between the wire core and the coating material. The first ultrasonic vibrating plate 426 uses the high-frequency oscillation signal emitted by an ultrasonic generator, converts it into a high-frequency mechanical oscillation through a transducer and propagates it into the medium, causing the liquid to flow and generating tens of thousands of tiny bubbles. The tiny bubbles (cavitation nuclei) existing in the liquid vibrate, grow, and gather energy under the action of the sound field, and when the energy reaches a certain level, the bubbles collapse sharply and release micro-jet flows to achieve the cleaning of the wire core surface;

[0062] The water squeezing assembly 429 includes a straight guide rod 4291 fixed on the outer side of the treatment cylinder 423 opposite to the water absorption area and an L-shaped lever 4292 fixed on the bottom end surface of the first annular cylinder 418. It also includes a push rod 4293 movably penetrating through the treatment cylinder 423. Two ends of the push rod 4293 are respectively fixedly connected with a hole plate 4294 and a V-shaped block 4295. A second spring 4297 fixedly connecting the V-shaped block 4295 and the treatment cylinder 423 is sleeved outside the push rod 4293. Among them, when the second spring 4297 is in a natural state, the hole plate 4294 is separated from the water-absorbing cotton block 4210. Ear plates 4296 are fixedly provided on both sides of the V-shaped block 4295, and the straight guide rod 4291 movably penetrates through the corresponding ear plates 4296.

[0063] It should be noted that when the wire core passes through the area where the pre-treatment mechanism 42 is located, it enters the cylindrical channel formed between the treatment cylinder 423 and the isolation ring 424. The cylindrical through-groove is just large enough for the wire core to pass through. Moreover, the contacts between the wire core and the treatment cylinder 423 and the isolation ring 424 are both hermetically sealed to prevent the cleaning liquid in the surface cleaning area from leaking out and to ensure the stable air pressure inside the plasma treatment chamber. During the pre-treatment of the wire core to be coated, one end of the wire core is inserted into the bottom end of the treatment cylinder 423 to block its lower port, and then the cleaning liquid is injected into the surface cleaning area, and the ultrasonic vibration plate 426 is started for cleaning work. When the cleaned wire core leaves the surface cleaning area and enters the water absorption area, the annular water absorption cotton block 4210 is used to absorb the cleaning liquid remaining on the surface of the wire core, and the water-absorbed wire core enters the surface treatment area. When the wire core entering this area blocks the inlet and outlet ports of this area, the inside of the plasma treatment chamber is evacuated, and the process gas is introduced, and the process gas is made to generate plasma by the plasma generator, and the surface of the wire core is roughened by using this plasma;

[0064] During the process of using the water absorption cotton block 4210 to absorb the cleaning liquid on the surface of the cleaned wire core, as the first annular cylinder 418 continuously rotates, the L-shaped lever 4292 connected to its bottom end will rotate synchronously. During the rotation of the L-shaped lever 4292, after it contacts the V-shaped block 4295, it will gradually squeeze the corresponding V-shaped block 4295, causing the V-shaped block 4295 to compress the corresponding second spring 4297 towards the treatment cylinder 423, and push the corresponding orifice plate 4294 to squeeze the water absorption cotton block 4210, squeezing out the cleaning liquid in the water absorption cotton block 4210, and flowing it back to the inside of the surface cleaning area through the two through-grooves 427 for reuse, reducing waste.

[0065] Specifically, as Figures 6 - 7 and Figures 13 - 14 shown, the post-treatment mechanism 43 includes an upper mounting plate 431 fixedly installed at the top end of the coating cylinder 411 by a locking bolt. A second annular cylinder 432 is fixedly provided at the top of the upper mounting plate 431. A second water receiving tray 435 and a third water receiving tray 437 are fixedly sleeved on the outer side of the second annular cylinder 432. A return water pipe 436 is communicated with the bottom of the third water receiving tray 437;

[0066] A heat exchanger fixed to the outside of the second annular cylinder 432 is installed on the return water pipe 436, which is used to displace the heat in the heat-absorbed water to ensure the continuous cooling effect on the cable body. A water pump is fixedly installed at the inner bottom of the second water receiving tray 435, which is used to pump the coolant that returns to the inside of the second water receiving tray 435 after heat exchange to the water-cooled area between the cable body and the second annular cylinder 432. The water outlet end of the water pump extends to the inside of the second annular cylinder 432. An ultrasonic vibration plate two 4310 is also installed on the second annular cylinder 432, which is similar to the aforementioned ultrasonic vibration plate one 426. Here, energy is released during the rapid collapse of bubbles, thereby generating a microjet. While cooling, the microjet is used to impact the cable coating layer, increasing the contact area and contact density between the coating layer and the wire core, improving the bonding force between the coating layer and the wire core. At the same time, it can also effectively improve the uniformity and density of the coating layer, reduce the generation of bubbles and defects, and improve the overall quality and service reliability of the cable;

[0067] A second column 433 is fixedly provided at the top of the second annular cylinder 432. The top of the second column 433 is fixedly connected to a cover cylinder 434. A ring strip 438 is fixedly provided at the inner bottom end of the cover cylinder 434. A mesh cylinder 439 is fixedly provided between the ring strip 438 and the inner top surface of the cover cylinder 434. An air hole is penetrated at the position where the top of the ring strip 438 is located inside the mesh cylinder 439. An air pump is fixedly installed on the outside of the cover cylinder 434. Among them, the air outlet end of the air pump extends to the area between the inside of the cover cylinder 434 and the mesh cylinder 439, so that the pumped cold air can be dispersed through the mesh cylinder 439 and evenly blown to the surface of the cable. On the one hand, it can further air-cool the cable, and on the other hand, it can dry the coolant remaining on the surface of the cable.

[0068] It should be noted that, similar to the aforementioned pretreatment process, when the extruded cable passes through the second annular cylinder 432 and the cover cylinder 434, mechanical seals are performed at the contact points between the outside of the cable and the through holes on the upper mounting plate 431, as well as the through holes on the ring strip 438 and the cover cylinder 434. Among them, during the process of cooling the completed coated wire core, when the completed coated wire core enters the area inside the second annular cylinder 432 from the inside of the covering material cylinder 411, the through hole on the upper mounting plate 431 is blocked. At this time, the cooling water in the second water receiving tray 435 is continuously pumped into the inside of the second annular cylinder 432 by the water pump, and the cable is cooled by the bottom-in and top-out method. The heat-absorbed and overflowed cooling water will flow into the third water receiving tray 437, and then after being heat-exchanged by the heat exchanger on the return water pipe 436, it will flow back into the second water receiving tray 435 for recycling;

[0069] After the cable completes the water cooling process, it will pass through the area where the cover cylinder 434 is located. During this period, an air pump is used to pump cold air into the cover cylinder 434 to further cool the cable and dry the moisture on the cable surface. The air entering the inner side of the mesh cylinder 439 during this process will continuously discharge from the air holes on the ring strip 438. The discharged gas can preliminarily cool the overflowing cooling water after heat absorption, which is used to cooperate with the heat exchanger to improve the cooling effect of the overflowing cooling water after heat absorption.

[0070] Specifically, as Figure 1 and Figures 4 - 5 shown, the fastening part 3 includes two vertical plates 31 and two side frames 33 fixed to the top of the frame 1. A cross bar 32 is fixedly connected between the two vertical plates 31. A left buckle plate 34 and a right buckle plate 35 are arranged between the two side frames 33. T-shaped guide bars 36 are fixedly provided on the opposite sides of the two side frames 33. The left buckle plate 34 and the right buckle plate 35 are both slidably installed on the T-shaped guide bars 36, and the cross bar 32 movably penetrates through the bottom ends of the left buckle plate 34 and the right buckle plate 35. Semi-circular buckle grooves 37 are opened at the top ends of the opposite sides of the left buckle plate 34 and the right buckle plate 35. Among them, the buckle groove 37 is used to buckle the annular convex plates on the discharge end of the main machine part 2 and the feed end of the machine head part 4 (such as the structure shown at the feed end of the covering material cylinder 411 in Figure 9 );

[0071] A driving part for driving the two to move relatively is arranged between the left buckle plate 34 and the right buckle plate 35. The driving part includes a first gear 39 rotatably installed between the left buckle plate 34 and the right buckle plate 35. Installation grooves and through grooves are opened on both the left buckle plate 34 and the right buckle plate 35. Among them, the installation groove on the left buckle plate 34 and the through groove on the right buckle plate 35 are horizontally collinear, and the installation groove on the right buckle plate 35 and the through groove on the left buckle plate 34 are horizontally collinear. The first gear 39 is driven by a motor to rotate. Rack bars 38 penetrating through the corresponding through grooves are fixedly provided inside the two installation grooves. The two rack bars 38 are both engaged with the first gear 39.

[0072] It should be noted that during the process of buckling the discharge end of the main machine part 2 and the feed end of the machine head part 4, after the annular convex plates on the docking ends of the two are facing and fitting, the motor is used to drive the first gear 39 to rotate, and the rotating first gear 39 is used to drive the two rack bars 38 to move away from each other, thereby driving the left buckle plate 34 and the right buckle plate 35 to move towards each other along the T-shaped guide bars 36 under the restriction of the cross bar 32, and using the buckle grooves 37 on the left buckle plate 34 and the right buckle plate 35 to buckle the discharge end of the main machine part 2 and the feed end of the machine head part 4, which is convenient and fast for disassembly and assembly.

[0073] Embodiment 2

[0074] Refer to the attached drawings of the specification Figure 1 and Figure 15, the present invention also provides a wire and cable extrusion molding machine. A marking part 5 is further provided on the top of the frame 1. The marking part 5 includes an upright frame 51 fixed on the top of the frame 1. The upright frame 51 is composed of a support column and a bearing plate fixed at the top of the support column. Two groups of vertical bars 52 are fixedly provided at the bottom of the bearing plate, with two in each group. A reciprocating marking assembly is provided between the two groups of vertical bars 52;

[0075] The reciprocating marking assembly includes a swing seat 54 provided between two vertical bars 52 in each group. Two swing bars 53 are rotatably installed at both ends of each swing seat 54 through shaft rods. One end of the swing bars 53 on both sides of the swing seat 54 is rotatably connected to the corresponding vertical bar 52 through a shaft rod. A buckle seat 55 is fixedly provided in the middle of the opposite sides of the two swing seats 54. Intermediate grooves 56 and end grooves 57 are opened in the middle of the opposite sides of the two buckle seats 55. A marking member is installed inside the intermediate groove 56. Among them, the marking member can be a printing head for spraying cable information or a nozzle for spraying paint. The length of the cable can be judged by the number of marks made by the marking member, which is convenient for the staff to record. An infrared rangefinder is installed inside the end groove 57. The transmitting unit and the receiving unit of the infrared rangefinder are respectively arranged inside the end grooves 57 on the two buckle seats 55;

[0076] A second gear 58 is provided on the outside of one of the two groups of vertical bars 52. One end of the shaft rod on the swing bar 53 corresponding to the second gear 58 is in transmission connection with the second gear 58. One of the second gears 58 is driven by a motor to rotate.

[0077] It should be noted that after the cable is double-stage cooled and the residual moisture on the surface of the cable is blown dry, the cable is kept in an upward conveying state. During this period, the corresponding second gear 58 is driven to rotate by the motor, and the rotating second gear 58 is used to drive the other second gear 48 to rotate, thereby driving the two swing seats 54 to approach and move away intermittently. In this process, as the two swing seats 54 approach each other, the two buckle seats 55 will also gradually buckle. When the infrared rangefinder detects that the two buckle seats 55 are close to the state of being fitted together, the marking member will automatically make a fixed-length mark on the conveying cable, which is convenient for counting.

[0078] In the above technical solution, the ultrasonic vibration plate one 426 and the ultrasonic vibration plate two 4310 mentioned both adopt ultrasonic vibration plates of model VGT-1012; the infrared rangefinder mentioned adopts a laser rangefinder of model SW-E60; the heat exchanger, water pump, air pump, motor, and plasma treatment device 425 mentioned are all existing products, and the specific models can be selected according to actual processing requirements and will not be elaborated here.
