Description

Technical Field

[0001] This invention belongs to the field of cable production technology, specifically a cable extruder. Background Technology

[0002] Wires and cables refer to materials used for power, electrical and related transmission purposes. There is no strict boundary between "wires" and "cables". Generally, products with fewer cores, smaller diameters and simpler structures are called wires, those without insulation are called bare wires, and others are called cables. The manufacturing process of cables involves more steps, requiring the use of cable extruders to create an insulation layer on the outside of the cable core to ensure insulation effectiveness and service life.

[0003] A Chinese patent with announcement number CN117400504B discloses an extruder for cable manufacturing. The invention has a scientific and reasonable structure, is safe and convenient to use, and is equipped with a feeding and efficient mixing mechanism. Through the cooperation of transmission gears, the stirring motor drives the collar and the transverse gear to rotate. Then, the longitudinal gear on the positioning rod further transmits the power, driving another collar to rotate in the opposite direction. This forces the two rotating frames to rotate in both directions simultaneously, and drives the stirring plate to rotate through the vertical rod, so as to stir the raw materials in both directions, prevent dead zones, and improve the stirring effect.

[0004] In current technology, when extruding cables, raw materials need to be fed into a hopper first. After being thoroughly mixed by the mixing components in the hopper, the materials are then conveyed to the cylinder for extrusion. Therefore, after all the material in the hopper has been conveyed to the cylinder, raw materials need to be added back into the cylinder for mixing. Since the addition of raw materials and the thorough mixing of the raw materials take a long time, there will be a situation where no raw materials are added into the cylinder during the process of adding raw materials and mixing, causing the extrusion work to be suspended, resulting in low working efficiency of the device.

[0005] Therefore, the present invention provides a cable extruder. Summary of the Invention

The push plates are arranged in pairs, and the two sets of push plates are respectively attached to two force plates. A drive assembly is provided below the cylinder.

[0010] Preferably, the drive assembly includes a drive motor located below the conveyor motor. The output shaft of the drive motor is fixedly mounted with two gears, and the outer wall of the rotating ring is fixedly mounted with toothed rings.

[0012] Preferably, the translation component includes two support plates, which are fixedly connected to the bracket. Each support plate has a sliding rod fixedly installed on its inner wall. The outer wall of the feeding seat has sliders that are symmetrically fixedly connected to the support plates. The inner walls of the two sliders are slidably connected to the outer walls of the two sliding rods, respectively. Elastic elements B are symmetrically fixedly installed between the outer wall of the slider and the inner wall of the support plate. A swing component is provided on one side of the support plate.

[0013] Preferably, the swing assembly includes an extension shaft fixedly installed on the inner wall of the slider, a positioning shaft fixedly installed on the inner wall of the support plate, a rotating plate rotatably installed on the outer wall of the positioning shaft, the inner wall of the rotating plate being slidably connected to the outer wall of the extension shaft, and the end of the rotating plate away from the extension shaft being located between two force-bearing plates.

[0014] Preferably, the inner wall of the feeding box is fixedly installed with several partitions, and the interior of the feeding box is formed with several hoppers through the partitions.

[0015] Preferably, two sets of material-gathering plates A, material-gathering plates B, and loose material blocks are symmetrically fixedly installed on the inner side of the feeding seat, with the loose material blocks on the same side located between material-gathering plates A and material-gathering plates B.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5As shown in the embodiment of the present invention, a cable extruder includes a cylinder 1. A conveyor shaft 2 is rotatably mounted on the inner wall of the cylinder 1. A conveyor motor 3 is fixedly mounted at one end of the cylinder 1, and the output end of the conveyor motor 3 is fixedly connected to one end of the conveyor shaft 2. Conveying blades 4 are fixedly mounted on the outer wall of the conveyor shaft 2. Hoppers 5 are symmetrically arranged above the cylinder 1. A stirring assembly is arranged inside the hoppers 5. A feed box 6 is fixedly mounted at the bottom of the hoppers 5. The outer wall of the feed box 6 is fixedly connected to the inner wall of the cylinder 1, and a baffle assembly is arranged inside the feed box 6. During cable production, raw materials for cable production are added to the hoppers 5. The stirring assembly thoroughly stirs the materials to make them evenly mixed. The evenly mixed materials are conveyed to the inside of the cylinder 1 through the feed box 6. At the same time, the conveyor motor 3 drives the conveyor shaft 2 to rotate. When the conveyor shaft 2 rotates, it drives the conveyor blades 4 to rotate. When the materials enter the cylinder 1, they are heated. At the same time, the rotation of the conveyor blades 4 conveys the materials, causing them to move away from the cylinder 1 and away from the conveyor motor 3. One end is extruded, thus forming the cable. Two hoppers 5 are installed above the cylinder 1 and connected to the cylinder 1 through feeding boxes 6. The feeding box 6 can be opened alternately by the material blocking component. When the feeding box 6 at the bottom of one hopper 5 is open for material conveying, the feeding box 6 at the bottom of the other hopper 5 will be closed. At this time, raw materials can be added and stirred. When the raw materials in the hopper 5 that is conveying material are exhausted, the other hopper 5 has completed the stirring work. At this time, the feeding box 6 below it can be opened to continue material conveying. The feeding box 6 at the bottom of the hopper 5 that has exhausted material will be closed. At this time, raw materials can be added and stirred. By repeating the above operation, the other hopper 5 can be prepared while one hopper 5 is conveying material, so that after one hopper 5 finishes conveying material, the other hopper 5 will continue to convey material. This ensures that the inside of the cylinder 1 can be continuously conveyed with material, effectively improving production efficiency.

[0024] like Figures 1 to 6As shown, the material blocking assembly includes two sets of positioning plates 7. Each set of positioning plates 7 is symmetrically fixedly installed on the outer wall of the feed box 6. An arc-shaped telescopic shaft 8 is fixedly installed on the outer wall of the positioning plate 7. A force-bearing plate 9 is fixedly installed between each set of arc-shaped telescopic shafts 8. An elastic element A10 is fixedly installed between each positioning plate 7 and the corresponding force-bearing plate 9. Each elastic element A10 is sleeved on the outer side of the arc-shaped telescopic shaft 8. A baffle 11 is fixedly installed on the outer wall of each force-bearing plate 9. The outer walls of the two baffles 11 are slidably connected to the inner walls of the two feed boxes 6. An extrusion assembly is provided on the outer wall of the cylinder 1. In the initial state, the two baffles 11 are located inside the two feed boxes 6, so that the two feed boxes 6 are in a closed state. At this time, the material cannot pass through the feed box 6 and thus cannot be discharged. When discharge is required, the extrusion assembly will reciprocate. When the extrusion assembly rotates forward, it will push one of the force-bearing plates 9. When the extrusion assembly rotates away from the corresponding feed box 6, the corresponding elastic element A10 is stretched. When the force plate 9 rotates, it drives the baffle 11 connected to it to rotate. When the baffle 11 rotates, it slides out from the inside of the feed box 6, thereby opening the feed box 6. The raw material in the hopper 5 above it will enter the interior of the cylinder 1 through the feed box 6. During this process, the other feed box 6 will remain closed. When the extrusion assembly reverses, the stretched elastic element A10 will contract under its own elastic force, thereby resetting the force plate 9. The resetting of the force plate 9 will cause the baffle 11 to re-enter the feed box 6 completely, and the feed box 6 will be closed again. After the feed box 6 is closed, the extrusion assembly will continue to reverse, thereby opening the other feed box 6 for material feeding. In summary, through the reciprocating rotation of the extrusion assembly, the two feed boxes 6 will open alternately, thereby achieving the effect of alternating material feeding from the two hoppers 5.

[0025] like Figures 1 to 7As shown, the extrusion assembly includes two rotating rings 12. The inner wall of the rotating rings 12 is rotatably connected to the outer wall of the cylinder 1. An arc-shaped plate is fixedly installed between the two rotating rings 12. Push plates 13 are symmetrically fixedly installed on the outer wall of the rotating rings 12. The push plates 13 are arranged in pairs, and the two sets of push plates 13 are respectively attached to two force plates 9. A drive assembly is provided below the cylinder 1. During the unloading operation, the drive assembly drives the rotating rings 12 to rotate reciprocally. When the rotating rings 12 rotate, they drive the push plates 13 to rotate. When the rotating rings 12 rotate clockwise, one set of push plates 13 pushes the corresponding force plate 9 forward. As the ring rotates, the other set of push plates 13 will move away from the corresponding force plate 9. When the ring 12 reverses, the two sets of push plates 13 will reset first. At this time, the force plate 9 that has rotated will reset under the action of the elastic element A10, while the other set of push plates 13 will move closer to the force plate 9 that has not rotated. After the force plate 9 that has rotated has completed its reset, the other set of push plates 13 will be in contact with the force plate 9 that has not rotated. Then, under the continuous reverse rotation of the ring 12, the force plate 9 that has not rotated will rotate under the push of the other set of push plates 13, thereby achieving the effect of alternating rotation of the two force plates 9.

[0026] like Figures 1 to 8 As shown, the drive assembly includes a drive motor 14, which is located below the conveyor motor 3. Two gears 15 are fixedly mounted on the output shaft of the drive motor 14. Gear rings 16 are fixedly mounted on the outer wall of the rotating ring 12. The teeth of the two gear rings 16 mesh with the teeth of the two gears 15 respectively. When the two hoppers 5 alternately feed materials, the drive motor 14 will drive the gears 15 to reciprocate. When the gears 15 reciprocate, they will drive the gear rings 16 that mesh with them to reciprocate as well. When the gear rings 16 rotate, they will drive the rotating ring 12 to rotate, thereby achieving the effect of driving the rotating ring 12 to reciprocate.

[0027] like Figures 8 to 9 and Figure 12As shown, a support 17 is provided on the outer side of the cylinder 1. Two hoppers 5 are fixedly installed on the inner wall of the support 17. A feeding box 19 is fixedly installed between the horizontal sections of the support 17. A feeding seat 20 is provided above the hoppers 5, and the feeding seat 20 is in contact with the feeding box 19. A translation component is provided on the outer wall of the feeding seat 20. The support 17 fixes the hoppers 5 and the feeding box 19, so that the hoppers 5 and the feeding box 19 are fixed in a suitable position. The feeding box 19 is used to carry the raw materials that need to be added into the hoppers 5. The feeding box 19 is in contact with the feeding seat 20. In the initial state, the bottom of the feeding box 19 is sealed by the feeding seat 20, and the raw materials in the feeding box 19 cannot fall. When it is necessary to... When adding raw materials into one of the hoppers 5, the translation component will automatically move the feeding seat 20 away from the hopper 5. After the feeding seat 20 moves, the bottom of the feeding box 19 will be offset from the top of the feeding seat 20, so that the bottom of the feeding box 19 is in an open state. The raw materials in the feeding box 19 will leak out from the bottom and fall onto the slope of the feeding seat 20 above the hopper 5, and then slide down the slope of the feeding seat 20 into the corresponding hopper 5. This achieves the effect of automatically adding raw materials into the hopper 5 without the need for manual back-and-forth movement to add raw materials into the two hoppers 5, and also without the need for manual judgment of which hopper 5 to add raw materials into, increasing the convenience of using the device.

[0028] like Figures 8 to 10 As shown, the translation component includes two support plates 21, which are fixedly connected to the bracket 17. Slide rods 22 are fixedly installed on the inner walls of each support plate 21. Slider blocks 23, slidably connected to the support plates 21, are symmetrically fixedly installed on the outer walls of the feeding seat 20. The inner walls of the two sliders 23 are slidably connected to the outer walls of the two slide rods 22, respectively. Elastic elements B24 are symmetrically fixed between the outer walls of the sliders 23 and the inner walls of the support plates 21. A swing component is provided on one side of the support plate 21. When the feeding seat 20 needs to move for feeding, the swing component pushes the sliders 23 to move along the slide rods 22. The movement of the sliders 23 causes the feeding seat 20 to move, thus displacing the feeding seat 20 from the feeding box 19 and automatically adding raw materials to the hopper 5. When the sliders 23 move, the elastic elements B24 deform under force. After the feeding operation is completed, the sliders 23 reset under the action of the elastic elements B24, thereby resetting the feeding seat 20.

[0029] like Figures 8 to 12As shown, the swing assembly includes an extension shaft 25 fixedly installed on the inner wall of the slider 23, a positioning shaft 26 fixedly installed on the inner wall of the support plate 21, and a rotating plate 27 rotatably installed on the outer wall of the positioning shaft 26. The inner wall of the rotating plate 27 is slidably connected to the outer wall of the extension shaft 25, and the end of the rotating plate 27 away from the extension shaft 25 is located between two force plates 9. When adding raw materials to the cylinder 1, the rotating ring 12 will push the corresponding force plate 9 to move through the push plate 13, thereby enabling the hopper 5 to perform material feeding. When the force plate 9 moves, it will squeeze one end of the rotating plate 27. After being squeezed, the rotating plate 27 will rotate around the positioning shaft 26. When the rotating plate 27 rotates, it will push the slider 23 to slide through the extension shaft 25, thereby causing the feeding seat 20 to move towards the hopper 5 that is feeding. When the feeding seat 20 moves towards the hopper 5 that is feeding, it will cause the feeding box 19 to feed into another hopper 5, thereby achieving the effect of automatically feeding into the corresponding hopper 5.

[0030] like Figure 11 As shown, several partitions 28 are fixedly installed on the inner wall of the feeding box 19, and several hoppers are formed inside the feeding box 19 through the partitions 28. The inside of the feeding box 19 is divided into multiple hoppers by the partitions 28. When storing raw materials, the feeding box 19 alternately places different types of raw materials into different hoppers. When the feeding box 19 feeds raw materials into the hopper 5, different types of raw materials will enter the hopper 5 at the same time, so that the raw materials are evenly distributed in the hopper 5, preventing different types of raw materials from stratifying in the hopper 5, which can effectively improve the subsequent mixing effect.

[0031] like Figures 10 and 11 As shown, two sets of material-aggregating plates A29, material-aggregating plate B30, and loose material blocks 31 are symmetrically fixedly installed on the inner side of the feeding seat 20. The loose material blocks 31 on the same side are located between the material-aggregating plates A29 and B30. When adding raw materials into the hopper 5, under the action of the hopper, different types of raw materials will slide down the slope of the feeding seat 20 at the same time. When the raw materials slide down the feeding seat 20, they will pass through the material-aggregating plate A29, loose material blocks 31 and material-aggregating plate B30 in sequence, so that the raw materials undergo polymerization-dispersion-polymerization when sliding down the feeding seat 20. This allows the raw materials to be initially mixed before entering the hopper 5, which improves the mixing effect and shortens the subsequent mixing time.

[0032] like Figure 1As shown, a base 32 is provided below the cylinder 1, and several fixed seats 33 are fixedly installed on the top of the base 32. The inner wall of the fixed seats 33 is fixedly connected to the outer wall of the cylinder 1. The drive motor 14 is fixedly installed on the top of the base 32, and the top of the base 32 is fixedly connected to the bottom of the bracket 17. The cylinder 1 is fixed in a suitable position by the fixed seats 33 to ensure the normal operation of cable production. The fixed seats 33, the bracket 17 and the drive motor 14 are all fixed on the top of the base 32. The base 32 supports the entire device and ensures the stability of the entire device.

[0033] Working Principle: During cable production, raw materials for cable production are added to the hopper 5. The mixing component thoroughly mixes the materials to ensure uniform mixing. The uniformly mixed materials are then conveyed to the cylinder 1 through the feed box 6. Simultaneously, the conveyor motor 3 drives the conveyor shaft 2 to rotate, which in turn drives the conveyor blades 4 to rotate. When the materials enter the cylinder 1, they are heated. The rotation of the conveyor blades 4 further conveys the materials, causing them to be extruded from the end of the cylinder 1 away from the conveyor motor 3, thus achieving cable forming. Two hoppers 5 are located above the cylinder 1 and are connected to the cylinder 1 via feed boxes 6. A baffle assembly allows the two feed boxes 6 to open alternately. When the feed box 6 at the bottom of one hopper 5... When material conveying is in operation, the feed box 6 at the bottom of the other hopper 5 will be closed. At this time, raw materials can be added to it and stirred. When the raw materials in the hopper 5 that is conveying material are exhausted, the other hopper 5 has completed the stirring process. At this time, the feed box 6 below it can be opened to continue material conveying. The feed box 6 at the bottom of the hopper 5 that has exhausted material will be closed. At this time, raw materials can be added to it and stirred. By repeating the above operation, while one hopper 5 is conveying material, the other hopper 5 can be prepared. This allows the other hopper 5 to continue conveying material after one hopper 5 has completed its conveying process, ensuring that the inside of the cylinder 1 can continuously receive material, effectively improving production efficiency.

[0034] Initially, the two baffles 11 are located inside the two feed boxes 6, respectively, keeping both feed boxes 6 closed. Material cannot pass through the feed boxes 6, thus preventing feeding. When feeding is required, the extrusion assembly reciprocates. When the extrusion assembly rotates forward, it pushes one of the force plates 9 away from the corresponding feed box 6, stretching the corresponding elastic element A10. The rotation of the force plate 9 causes the connected baffle 11 to rotate, sliding out from the inside of the feed box 6, thus opening the feed box 6. The raw material in hopper 5 enters the interior of cylinder 1 through feed box 6. During this process, the other feed box 6 remains closed. When the extrusion assembly reverses, the elongated elastic element A10 contracts under its own elastic force, thereby resetting the force plate 9. The resetting of the force plate 9 causes the baffle 11 to fully re-enter the feed box 6, and the feed box 6 is closed again. After the feed box 6 is closed, the extrusion assembly continues to reverse, causing the other feed box 6 to open for material feeding. In summary, through the reciprocating rotation of the extrusion assembly, the two feed boxes 6 are opened alternately, thereby achieving... The alternating feeding effect of the two hoppers 5 involves the drive assembly driving the rotating ring 12 to reciprocate during feeding. As the ring 12 rotates, it drives the push plates 13 to rotate. When the ring 12 rotates clockwise, one set of push plates 13 pushes the corresponding force plate 9 to rotate, while the other set of push plates 13 moves away from the corresponding force plate 9. When the ring 12 rotates counterclockwise, both sets of push plates 13 first reset. The rotating force plate 9 is then reset by the elastic element A10, while the other set of push plates 13 moves closer to the stationary force plate 9. When the rotation... After the moving force plate 9 completes its reset, another set of push plates 13 comes into contact with the unrotated force plate 9. Then, under the continuous reverse rotation of the rotating ring 12, the unrotated force plate 9 will rotate under the push of the other set of push plates 13, thereby achieving the effect of alternating rotation of the two force plates 9. When the two hoppers 5 alternately discharge materials, the drive motor 14 will drive the gear 15 to reciprocate. When the gear 15 reciprocates, it will drive the gear ring 16 meshing with it to reciprocate as well. When the gear ring 16 rotates, it will drive the rotating ring 12 to rotate, thereby achieving the effect of driving the rotating ring 12 to reciprocate.

[0035] The hopper 5 and the feeding box 19 are fixed in place by the bracket 17, ensuring they are in the correct positions. The feeding box 19 is used to hold the raw materials to be added to the hopper 5. The feeding box 19 is in contact with the discharge seat 20. In the initial state, the bottom of the feeding box 19 is sealed by the discharge seat 20, preventing the raw materials inside from falling. When raw materials need to be added to one of the hoppers 5, the translation component automatically moves the discharge seat 20 away from that hopper 5. Then, the bottom of the feeding box 19 will be offset from the top of the feeding seat 20, so that the bottom of the feeding box 19 is in the open state. The raw material in the feeding box 19 will leak out from the bottom and fall onto the slope of the feeding seat 20 above the hopper 5. The leaked raw material will slide down the slope of the feeding seat 20 into the corresponding hopper 5, realizing the effect of automatically adding raw material into the hopper 5. There is no need for manual back-and-forth movement to add raw material into the two hoppers 5, nor is there a need for manual judgment on which hopper 5 to add raw material, thus increasing the convenience of using the device.

[0036] When the feeding seat 20 needs to move for feeding, the swing assembly pushes the slider 23 to move along the slide bar 22. The movement of the slider 23 causes the feeding seat 20 to move, thus displacing the feeding seat 20 from the feeding box 19, achieving the effect of automatically adding raw materials to the hopper 5. When the slider 23 moves, the elastic element B24 deforms under force. After the feeding operation is completed, the slider 23 resets under the action of the elastic element B24, thus resetting the feeding seat 20. When adding raw materials to the cylinder 1, the rotating ring 12 is pushed by the push plate 13. The corresponding force plate 9 moves, thereby enabling the hopper 5 to perform material feeding. When the force plate 9 moves, it will press one end of the rotating plate 27. After being pressed, the rotating plate 27 will rotate around the positioning shaft 26. When the rotating plate 27 rotates, it will push the slider 23 to slide through the extension shaft 25, thereby causing the feeding seat 20 to move towards the hopper 5 that is feeding. The movement of the feeding seat 20 towards the hopper 5 will cause the feeding box 19 to feed material into another hopper 5, thereby achieving the effect of automatically feeding material into the corresponding hopper 5.

[0037] The interior of the feeding box 19 is divided into multiple hoppers by a partition 28. When storing raw materials, the feeding box 19 alternately places different types of raw materials into different hoppers. When the feeding box 19 feeds raw materials into the hopper 5, different types of raw materials enter the hopper 5 simultaneously, making the raw materials evenly distributed in the hopper 5 and preventing the different types of raw materials from stratifying in the hopper 5. This can effectively improve the subsequent mixing effect. When adding raw materials into the hopper 5, under the action of the hoppers, different types of raw materials will slide down the slope of the discharge seat 20 at the same time. When the raw materials slide down the discharge seat 20, they will pass through the aggregation plate A29, the bulk block 31 and the aggregation plate B30 in sequence, so that the raw materials undergo aggregation-dispersion-aggregation when sliding down the discharge seat 20. This allows the raw materials to be initially mixed before entering the hopper 5, which not only improves the mixing effect but also shortens the subsequent mixing time.
