[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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.

[0036] Please refer to Figures 1 - 7 As shown in the figure, this embodiment is an extrusion and shaping device and method for the production and processing of power cables, including an extruder 1. An extrusion head 2 is arranged on one side of the extruder 1. A base 3 is placed on the side of the extrusion head 2 close to the bottom. A cooling box 4 is fixedly installed on the side of the upper surface of the base 3 close to the end of the extrusion head 2. A feeding mechanism is slidably connected to the cooling box 4;

[0037] The feeding mechanism includes a moving seat 5 slidably connected to the upper surface of the cooling box 4. The moving seat 5 is in an inverted U shape. Two symmetrically arranged clamping blocks 7 are slidably connected to the lower surface of the moving seat 5. A switching mechanism is arranged on the side of the base 3 close to the end of the cooling box 4;

[0038] The switching mechanism includes two rotating discs 9 rotatably connected to two limiting frames 8. An opening groove 10 for the cable to pass through is formed on the surface of the rotating disc 9. The traction rope is sequentially passed through the opening groove 10, the cooling box 4 and the extruder 1 and connected to the cable. The traction rope pulls the cable to move. A plurality of annularly arranged first mounting plates 13 are fixedly connected between the two rotating discs 9. A first rotating shaft 11 is coaxially and fixedly connected between the two rotating discs 9 to ensure the synchronous rotation of the two rotating discs 9. Two vertically spaced first mounting frames 14 and second mounting frames 15 are arranged directly below the first mounting plate 13. Chain plates 31 are arranged on one side of each of the first mounting frame 14 and the second mounting frame 15. Shaping grooves 33 for shaping the cable are formed on the surfaces of the two chain plates 31;

[0039] In this embodiment, the shaping groove 33 has different shapes, such as oval, circular, etc. One side of the cooling box 4 is horizontally slidably connected with a pushing piece 18. The pushing piece 18 is located between two vertically spaced chain plates 31. When the moving seat 5 clamps the cable and moves it towards the switching mechanism, the movement of the moving seat 5 pushes the pushing piece 18 to move between the two chain plates 31, separating the two chain plates 31 from each other;

[0040] There are multiple mounting frames one 14 and mounting frames two 15, and they are arranged in an annular array. A rotating motor four for driving the rotating disc 9 to rotate is fixedly installed on the limiting frame 8. The motor four is a servo motor. When the rotating disc 9 rotates between the two limiting frames 8, the position of the corresponding mounting plate one 13 can be switched. Since the specifications and dimensions of the shaping grooves 33 between the two chain plates 31 are different, the corresponding chain plates 31 can be switched according to different specifications and shaping requirements of the cable.

[0041] Two symmetrically arranged rotating rods 12 are rotatably connected to the inner wall of the cooling box 4. The two rotating rods 12 penetrate and are slidably connected with a mounting block 25. The mounting block 25 is penetrated and fixedly connected with a nozzle 26. The nozzle 26 is connected to an external hose. Cooling water is transported to the nozzle 26 through a delivery pump, and the nozzle 26 cools the cable extruded from the extrusion head 2. The outer wall of the mounting block 25 is penetrated and screwed with a fixing knob, and the position of the mounting block 25 on the rotating rod 12 is fixed through the fixing knob.

[0042] A spiral groove 22 is formed on the outer wall of the rotating rod 12. Two symmetrically arranged mounting plates two 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 two 23. The ends of the sliding columns 24 are located in the spiral groove 22 and are slidably connected with 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, and the two ends of the spiral groove 22 are arranged in a straight line;

[0043] In this embodiment: As the moving seat 5 moves, the rotating rod 12 can be deflected, so that the spraying range of the nozzle 26 on the mounting block 25 can be increased, thereby realizing 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 line position of the spiral groove 22, the rotating rod 12 will not rotate, and the nozzle 26 remains in a horizontal state.

[0044] Support rollers are arranged at the bottom inside the cooling box 4. The support rollers are spaced at the bottom inside the cooling box 4. The cable is supported by the support rollers to prevent the cable from sagging due to gravity during traction and from forming bends or deformations during cooling, which affects the straightness and appearance quality of the cable.

[0045] A mounting seat 6 is fixedly connected to the upper surface of the moving seat 5. A second screw 34 is rotatably connected to the inner fixed axis of the mounting seat 6. The second screw 34 passes through two clamping blocks 7 and is threadedly connected to the two clamping blocks 7. Opposite switching structures are provided at the threaded connection of the two clamping blocks 7 and the second screw 34. A first motor is fixedly installed on one side of the outer wall of the mounting seat 6, and the output end of the first motor is connected to the second screw 34, thereby driving the second screw 34 to rotate, thereby driving the second screw 34 to rotate. The second screw 34 drives the two clamping blocks 7 to move away from each other or close to each other, so as to clamp the cooled cable.

[0046] In this embodiment, a connecting plate 35 is fixedly connected to one side of the bottom end of the moving seat 5, and a pressing plate 36 is fixedly connected to one side of the moving seat 5. A guide rail 27 that penetrates the connecting plate 35 and is horizontally slidably connected to the connecting plate 35 is fixedly connected to the outer wall of the cooling box 4. A connecting block 29 is fixedly connected to the lower surface of the connecting plate 35. The connecting block 29 is penetrated and threadedly connected to a first screw 28. A limiting piece for limiting the rotation of the first screw 28 is fixedly connected to the outer wall of the cooling box 4. A second motor is fixedly installed on one side of the outer wall of the cooling box 4, driving the first screw 28 to rotate so that the connecting block 29 screwed thereto moves horizontally, and the moving seat 5 fixedly connected to the connecting plate 35 moves on the cooling box 4, so as to adjust the position of the moving seat 5.

[0047] In this embodiment, a limiting block 19 is fixedly connected to the surface of the cooling box 4. A limiting strip 20 is penetrated and horizontally slidably connected to the limiting block 19. One end of the limiting strip 20 away from the cooling box 4 is fixedly connected to a pushing piece 18. A retaining piece 37 is fixedly connected to one end of the limiting strip 20 away from the pushing piece 18. A second spring 21 that abuts against the retaining piece 37 and the limiting block 19 is sleeved on the outer contour of the limiting strip 20. By providing the second spring 21, when the moving seat 5 moves away from the pushing piece 18, the pushing piece 18 can be reset and separated from the two chain plates 31. A nozzle 26 in contact with the retaining piece 37 is fixedly connected to the outer wall of the moving seat 5. When the moving seat 5 moves towards the pushing piece 18 and contacts the end of the retaining piece 37, it thus pushes the pushing piece 18 to move between the two chain plates 31, so that the two chain plates 31 are separated.

[0048] Two symmetrically arranged limiting rods 16 are fixedly connected to the lower surface of the first mounting plate 13. The two limiting rods 16 penetrate the first mounting frame 14 and are vertically slidably connected to the second mounting frame 15. One end of the limiting rod 16 away from the first mounting plate 13 is fixedly connected to the second mounting frame 15. A first spring 17 that abuts against the first mounting frame 14 and the first mounting plate 13 is sleeved on the outer contour of the limiting rod 16;

[0049] The end of the mounting plate 13 away from the mounting frame 14 is fixedly connected to the fixing frame 30, and the surface of the fixing frame 30 is provided with a through groove for limiting the axial end of the chain plate 31. The mounting frame 14 is rotatably connected to the surface of the mounting frame 2 15 with a sprocket 32 ​​that meshes with the chain plate 31. By setting a spring 17, the mounting frame 14 and the mounting frame 2 15 can be automatically reset, so as to facilitate the subsequent replacement of chain plates 31 of different sizes, so as to be suitable for cable shaping of different sizes. The outer walls of the mounting frame 14 and the mounting frame 2 15 are fixedly installed with a motor 3, and the output end of the motor 3 is connected to the chain plate 31 through the sprocket 32. When the motor 3 is started, the chain plates 31 on the mounting frame 14 and the mounting frame 2 15 can be driven to move, and the cables can be shaped while being transported.

[0050] A method for using an extrusion molding device for producing and processing a power cable comprises the following steps:

[0051] Step 1: Switching process, switching the specifications and models of the two chain plates 31 through a switching mechanism;

[0052] Step 2: Cooling treatment, the rotating rod 12 is deflected to expand the spray range of the nozzle 26 for spraying the cable, so as to achieve uniform spraying of the cable extruded from the extrusion head 2.

[0053] Step 3: Clamping and conveying: the wires and cables are clamped by two clamping blocks 7 and conveyed between the two chain plates 31 .

[0054] Step 4: Auxiliary conveying, the moving seat 5 moves and pushes the pushing piece 18 to move between the two chain plates 31, so that the two chain plates 31 are separated, so as to facilitate the rapid conveying of the cable to between the two chain plates 31 for shaping operation.

[0055] like Figures 1 - 7 As shown, the working process and principle of the present invention are as follows:

[0056] Step 1, the extruder 1 performs extrusion production on the power cable. When the corresponding chain plate 31 needs to be switched, the motor 4 is started to drive the rotating disk 9 to rotate. When the rotating disk 9 rotates between the two limit frames 8, the position of the corresponding mounting plate 13 can be switched, so as to realize the replacement of chain plates 31 of different sizes and specifications, and replace the specifications and models of the extruder head 2 of the extruder 1. The motor 2 is started to drive the connecting block 29 to rotate, so that the movable seat 5 fixedly connected to the connecting plate 35 is moved on the cooling box 4, and the position of the movable seat 5 is adjusted. The screw 28 is driven to rotate to move the connecting block 29 screwed thereto in the horizontal direction, and the movable seat 5 fixedly connected to the connecting plate 35 is moved on the cooling box 4, so that the movable seat 5 moves toward the extruder 1.

[0057] As the movable seat 5 moves, the rotating rod 12 can be deflected, increasing the spraying range of the spray head 26 on the mounting block 25, thereby achieving uniform spraying of the cable extruded from the extrusion head 2 and ensuring that the extruded power cable can be fully cooled. Then, start the first motor located on one side of the mounting seat 6 to drive the second screw 34 to rotate. The second screw 34 drives the two clamping blocks 7 to move away from or close to each other to clamp the cooled cable.

[0058] Step 2: Start the second motor to drive the connecting block 29 to rotate again, causing the movable seat 5 to move away from the extruder 1 and convey the cable clamped by the clamping blocks 7 between the two chain plates 31. As the movable seat 5 moves towards one end in the direction of the chain plate 31, the pressing plate 36 on the movable seat 5 contacts the stop piece 37, thereby overcoming the elastic force of the second spring 21 to push the pushing piece 18 to move between the two chain plates 31, so that the two chain plates 31 are separated, facilitating the insertion of the cable end between the two chain plates 31. The two clamping blocks 7 release the clamping of the cable. By reversing the rotation of the second motor, the movable seat 5 moves away from the chain plate 31, so that the pressing plate 36 is separated from the stop piece 37. Under the action of the second spring 21, the pushing piece 18 can be reset and separated from the two chain plates 31. The two chain plates 31 approach each other under the action of the first spring 17 and contact the cable. Start the third motor on the outer walls of the first mounting frame 14 and the second mounting frame 15 to shape the cable while conveying it.
