[0001] This invention relates to the field of power cable production technology, and in particular to an extrusion molding equipment and method for power cable production and processing. Background Technology

[0002] During cable manufacturing, extrusion molding equipment is used to extrude the cross-section of the cable into a specific shape. Cable extrusion molding equipment is usually used to extrude the insulation layer or sheath of the cable into a specific shape to improve its performance or adapt to different application requirements. Extrusion molding equipment ensures that the cable has the required appearance and structural characteristics by heating and extruding the material, and is commonly used in cable production and processing. Among them, the Chinese invention patent, publication number CN118782319B, describes an extrusion molding device for the production and processing of high-temperature resistant cables. This device uses a support beam to move the position of a flipping seat on a support shaft upwards, causing the stepped groove of the second extrusion roller to disengage from the connecting groove of the first extrusion roller. The support shaft and support beam are rotatably connected, causing the flipping seat to rotate and rotate the fixed seat. Although the fixed seat and connecting seat are respectively bolted to the flipping seat and the mounting base, improving the ease of replacement, increasing usability, and enhancing the adaptability of extrusion size and shape, it has certain drawbacks in actual use. It is inconvenient to extrude and mold cables of different sizes, making it difficult to quickly switch between different sizes and specifications of cable molding, and it is difficult to maintain production efficiency while switching between them.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-7 As shown, this embodiment is an extrusion molding equipment and method for power cable production and processing, including an extruder 1, an extrusion head 2 is provided on one side of the extruder 1, a base 3 is placed on the side of the extrusion head 2 near the bottom, a cooling box 4 is fixedly installed on the upper surface of the base 3 near the end of the extrusion head 2, and a feeding mechanism is slidably connected to the cooling box 4. The feeding mechanism includes a movable seat 5 that is slidably connected to the upper surface of the cooling box 4. The movable seat 5 is in an inverted U-shape. Two symmetrically arranged clamping blocks 7 are slidably connected to the lower surface of the movable seat 5. A switching mechanism is provided on the side of the base 3 near the end of the cooling box 4. The switching mechanism includes two rotating disks 9 rotatably connected to two limit frames 8. The surface of the rotating disks 9 is provided with an opening groove 10 for the cable to pass through. The traction rope passes through the opening groove 10, the cooling box 4 and the extruder 1 in sequence and is connected to the cable. The traction rope pulls the cable to move. Multiple ring array mounting plates 13 are fixedly connected between the two rotating disks 9. A rotating shaft 11 is fixedly connected between the two rotating disks 9 on the same axis to ensure that the two rotating disks 9 rotate synchronously. Two vertically spaced mounting frames 14 and 25 are provided directly below the mounting plate 13. A chain plate 31 is provided on one side of each mounting frame 14 and mounting frame 2 15. The surface of the two chain plates 31 is provided with a shaping groove 33 for shaping the cable. In this embodiment, the shaping groove 33 has different shapes, such as ellipse, circle, etc. A push plate 18 is horizontally slidably connected to one side of the cooling box 4. The push plate 18 is located between two vertically spaced chain plates 31. When the moving seat 5 clamps the cable and moves it in the direction of the switching mechanism, the movement of the moving seat 5 pushes the push plate 18 to move between the two chain plates 31, so that the two chain plates 31 are separated. Multiple mounting brackets 14 and 15 are provided and arranged in a circular array. A drive rotating disk 9 is fixedly installed on the limiting frame 8 to rotate the motor 4. The motor 4 is a servo motor. When the rotating disk 9 rotates between the two limiting frames 8, it can switch the position of the corresponding mounting plate 13. The different specifications and dimensions of the shaping groove 33 between the two chain plates 31 can switch the corresponding chain plate 31 according to the different specifications and shaping requirements of the cable.

[0018] The inner wall of the cooling box 4 is rotatably connected to two symmetrically arranged rotating rods 12. The two rotating rods 12 are slidably connected to a mounting block 25. The mounting block 25 is slidably connected to a nozzle 26. The nozzle 26 is connected to an external hose. Cooling water is delivered to the nozzle 26 by a delivery pump. The nozzle 26 cools the cable extruded from the extruder head 2. The outer wall of the mounting block 25 is spun with a fixing knob. The fixing knob fixes the position of the mounting block 25 on the rotating rod 12.

[0019] The outer wall of the rotating rod 12 is provided with a spiral groove 22. Two symmetrically arranged mounting plates 23 are fixedly connected to the lower surface of the moving seat 5. Sliding columns 24 are fixedly connected to the opposite sides of the two mounting plates 23. The ends of the sliding columns 24 are located in the spiral groove 22 and are slidably connected to the spiral groove 22. When the moving seat 5 moves towards the extrusion head 2, the sliding columns 24 slide in the spiral groove 22. The two ends of the spiral groove 22 are arranged in a straight line. In this embodiment: as the moving seat 5 moves, the rotating rod 12 can be deflected, thereby increasing the spray range of the nozzle 26 on the mounting block 25, so as to achieve uniform spraying of the cable extruded from the extrusion head 2, ensuring that the cable can be fully cooled, and facilitating the clamping block 7 to clamp and transport it. When the moving seat 5 moves to the straight position of the spiral groove 22, the rotating rod 12 will not rotate, keeping the nozzle 26 in a horizontal state.

[0020] The bottom of the cooling box 4 is equipped with support rollers, which are spaced apart to support the cable and prevent it from sag due to gravity during traction and from bending or deforming during cooling, thus affecting the straightness and appearance quality of the cable.

[0021] A mounting base 6 is fixedly connected to the upper surface of the movable base 5. A screw 34 is rotatably connected to the mounting base 6. The screw 34 passes through two clamping blocks 7 and is screwed to the two clamping blocks 7. The two clamping blocks 7 are provided with opposite switching structures at the screwing points of the screw 34. A motor is fixedly installed on one side of the outer wall of the mounting base 6. The output end of the motor is connected to the screw 34, thereby driving the screw 34 to rotate. The screw 34 drives the two clamping blocks 7 to move away from each other or move closer to each other, so as to clamp the cooled cable.

[0022] In this embodiment, a connecting plate 35 is fixedly connected to one side of the bottom of the movable seat 5, and a pressing plate 36 is fixedly connected to one side of the movable seat 5. A guide rail 27 is fixedly connected to the outer wall of the cooling box 4, passing through the connecting plate 35 and sliding horizontally connected to the connecting plate 35. A connecting block 29 is fixedly connected to the lower surface of the connecting plate 35. A screw 28 is screwed through the connecting block 29. A limiting plate is fixedly connected to the outer wall of the cooling box 4 to limit the rotation of the screw 28. A motor is fixedly installed on one side of the outer wall of the cooling box 4 to drive the screw 28 to rotate, causing the connecting block 29 screwed to it to move in the horizontal direction. The movable seat 5, which is fixedly connected to the connecting plate 35, moves on the cooling box 4, thereby adjusting the position of the movable seat 5.

[0023] In this embodiment, a limiting block 19 is fixedly connected to the surface of the cooling box 4. The limiting block 19 is penetrated and horizontally slidably connected to a limiting strip 20. The end of the limiting strip 20 away from the cooling box 4 is fixedly connected to the pushing plate 18. A baffle 37 is fixedly connected to the end of the limiting strip 20 away from the pushing plate 18. A spring 21 is sleeved on the outer contour of the limiting strip 20, which abuts against the baffle 37 and the limiting block 19. By setting the spring 21, when the moving seat 5 is away from the direction of the pushing plate 18, the pushing plate 18 can be reset and separated from the two chain plates 31. A pressing plate 36 that contacts the baffle 37 is fixedly connected to the outer wall of the moving seat 5. When the moving seat 5 moves towards the pushing plate 18 and contacts the end of the baffle 37, it pushes the pushing plate 18 to move between the two chain plates 31, thereby separating the two chain plates 31.

[0024] Two symmetrically arranged limiting rods 16 are fixedly connected to the lower surface of the mounting plate 13. The two limiting rods 16 pass through the mounting frame 14 and are vertically slidably connected to the mounting frame 14. The end of the limiting rod 16 away from the mounting plate 13 is fixedly connected to the mounting frame 2 15. A spring 17 is sleeved on the outer contour of the limiting rod 16 to abut against the mounting frame 14 and the mounting plate 13. A fixing frame 30 is fixedly connected to the end of mounting plate 13 away from mounting frame 14. The surface of the fixing frame 30 has a through groove for limiting the shaft end of the chain plate 31. Mounting frame 14 and mounting frame 2 15 are rotatably connected to a sprocket 32 ​​that meshes with the chain plate 31. By setting spring 17, mounting frame 14 and mounting frame 2 15 can be automatically reset, which facilitates the replacement of chain plates 31 of different sizes, thus making it suitable for shaping cables of different sizes. Motor 3 is fixedly installed on the outer wall of mounting frame 14 and mounting frame 2 15. The output end of motor 3 is connected to the chain plate 31 through sprocket 32. When motor 3 is started, it can drive the chain plate 31 on mounting frame 14 and mounting frame 2 15 to move, and shape the cable while it is being transported.

[0025] A method of using an extrusion molding equipment for power cable production and processing includes the following steps: Step 1: Switching process, the specifications and models of the two chain plates 31 are switched through the switching mechanism; Step 2: Cooling treatment. Rotating rod 12 is deflected to expand the spray range of nozzle 26 on the cable, thereby achieving uniform spraying of the cable extruded from extrusion head 2.

[0026] Step 3: Clamping and conveying. The wires and cables are clamped by two clamping blocks 7 and conveyed between two chain plates 31.

[0027] Step 4: Auxiliary conveying. The moving seat 5 moves and pushes the pusher plate 18 between the two chain plates 31 to separate the two chain plates 31, so that the cable can be quickly conveyed between the two chain plates 31 for shaping operation.

[0028] like Figures 1-7 As shown, the working process and principle of this invention are as follows: Step 1: Extruder 1 extrudes power cables. When it is necessary to switch the corresponding chain plate 31, motor 4 is started to drive the rotating disk 9 to rotate. When the rotating disk 9 rotates between the two limit frames 8, it can switch the position of the corresponding mounting plate 13, thereby realizing the replacement of chain plates 31 of different sizes and specifications, and changing the specifications and models of the extrusion head 2 of extruder 1. Motor 2 is started to drive the connecting block 29 to rotate, thereby moving the movable seat 5 fixedly connected to the connecting plate 35 on the cooling box 4, realizing the adjustment of the position of the movable seat 5. Screw 28 is driven to rotate to move the connecting block 29 screwed to it in the horizontal direction, and the movable seat 5 fixedly connected to the connecting plate 35 moves on the cooling box 4, so that the movable seat 5 moves closer to the extruder 1. As the movable seat 5 moves, the rotating rod 12 can be deflected, increasing the spray range of the nozzle 26 on the mounting block 25, thereby achieving uniform spraying of the cable extruded from the extrusion head 2, ensuring that the extruded power cable can be fully cooled. Then, the motor 1 located on one side of the mounting seat 6 is started, driving the screw 2 34 to rotate. The screw 2 34 drives the two clamping blocks 7 to move away from or closer to each other, clamping the cooled cable. Step two: Start motor two again to drive connecting block 29 to rotate, causing moving seat 5 to move away from extruder 1 and convey the cable held by clamping block 7 between the two chain plates 31. As moving seat 5 moves towards the chain plates 31, pressing plate 36 on moving seat 5 contacts baffle 37, thereby overcoming the elastic force of spring two 21 and pushing push plate 18 between the two chain plates 31, thus separating the two chain plates 31, making it easier to insert the cable end between the two chain plates 31. The two clamping blocks 7 release their clamping on the cable. Motor two rotates in the opposite direction, causing moving seat 5 to move away from chain plates 31, thus separating pressing plate 36 from baffle 37. Under the action of spring two 21, push plate 18 can reset and separate from the two chain plates 31. The two chain plates 31 approach each other under the action of spring one 17 and contact the cable. Start motor three on the outer wall of mounting frame one 14 and mounting frame two 15 to shape the cable while conveying it.
