Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to an extrusion device for insulation layer of wind power cable. Background Technology

[0002] Cables are required in wind power generation. The insulation layer of a cable is a layer of material located outside the cable conductor. It is used to provide insulation performance and prevent short circuits or leakage when current comes into contact with the conductor or the outside environment. The production of cable insulation layer requires an extruder. Its main function is to coat the cable conductor with insulating material by extrusion to form the cable insulation layer. The extruder needs a feeding device to continuously and automatically feed the insulating material into the extruder for extrusion.

[0003] Existing technologies, such as Chinese Patent No. CN221677976U, disclose a feeding device for a cable insulation extruder, including a storage bin, a housing, and a machine body. A first servo motor is fixedly connected to the outer wall of the front end of the storage bin near the middle. The output end of the first servo motor passes through the storage bin and is fixedly connected to a stirring shaft. Multiple stirring blades are fixedly connected to the outer wall of the stirring shaft. A discharge port is fixedly connected to the lower end of the storage bin, and a waste bin is fixedly connected to the upper surface of the storage bin. In this invention, starting the first servo motor drives the stirring shaft to stir the insulation material, preventing the insulation material from accumulating excessively and causing obstructed feeding. Starting the third servo motor allows the insulation material to be fed into the extruder via a auger shaft. The insulation material is evenly fed to the extruder's feed port, ensuring stable and uniform feeding, thus making it highly practical. However, this utility model uses two sets of motors to drive the crushing and mixing of materials separately, which increases the cost of the equipment. Furthermore, due to the addition of the feed inlet structure, material blockage may still occur at the connection between the crushing bin, the storage bin and the shell.

[0004] To address the issue of large-particle insulation material causing blockage or affecting extrusion quality in wind power cable insulation extrusion devices, most existing equipment directly feeds the insulation material into the hopper and extrudes it through the extruder. This process can lead to blockage of the insulation material, resulting in uneven distribution of the cable insulation layer during extrusion. Furthermore, the large particle size of some insulation materials may make it difficult to completely melt them during extruder heating, thus affecting the quality of the cable insulation layer. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that large-particle insulation materials may cause blockage or affect the extrusion quality when feeding into the wind power cable insulation extrusion device, and to propose a wind power cable insulation extrusion device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wind power cable insulation layer extrusion device, comprising an extruder, a support, a storage box, a feeding box, and a feeding mechanism, wherein the support is disposed on one side of the extruder, the storage box is fixedly connected to the surface of the support, the feeding box is fixedly connected to the surface of the storage box, and the feeding mechanism is disposed on the surface of the storage box;

[0007] The feeding mechanism includes a motor, which is fixedly mounted on the surface of the storage box. A stirring rod is fixedly connected to the output end of the motor. A crushing roller is rotatably connected to the inner wall of the feeding box. Guide rods are fixedly connected to the surfaces of both the storage box and the feeding box. A toothed plate is slidably connected to the surface of the guide rod. A half gear is fixedly connected to the surface of the stirring rod and meshes with the surface of the toothed plate. A gear is fixedly connected to the surface of the crushing roller and meshes with the surface of the toothed plate. A spring is sleeved and connected to the surface of the guide rod.

[0008] Furthermore, one end of the spring is fixedly connected to the surface of the guide rod, the other end of the spring is fixedly connected to the surface of the toothed plate, the stirring rod is rotatably connected to the inner wall of the storage box, and the stirring rod is disposed inside the storage box.

[0009] Furthermore, an auxiliary roller is rotatably connected to the inner wall of the feeding box, and gears are fixedly connected to the surfaces of both the crushing roller and the auxiliary roller, with the two sets of gears meshing together.

[0010] Furthermore, both the crushing roller and the auxiliary roller are located inside the feeding box, and the auxiliary roller cooperates with the crushing roller.

[0011] Furthermore, the surface of the bracket is provided with an auxiliary mechanism, which includes a slide groove. The slide groove is formed on the surface of the bracket, and a strike plate is slidably connected to the surface of the slide groove. A cylinder is fixedly connected to the surface of the half gear, and a connecting rod is rotatably connected to the surface of the cylinder. The end of the connecting rod away from the cylinder is rotatably connected to the surface of the strike plate.

[0012] Furthermore, the surface of the toothed plate is fixedly connected with impact blocks, and there are two sets of impact blocks. One set of impact blocks cooperates with the storage box, and the other set of impact blocks cooperates with the unloading box.

[0013] Furthermore, a conveying pipe is fixedly connected to the surface of the storage box, and the end of the conveying pipe away from the storage box is fixedly connected to the surface of the extruder. A second motor is fixedly installed on the surface of the conveying pipe, and a conveying auger is fixedly connected to the output end of the second motor. The conveying auger is located inside the conveying pipe.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, by setting a feeding mechanism, materials are fed from the feeding box into the storage box. When feeding is required, motor two is started to rotate the conveying auger, which, together with the conveying pipe, transports the materials to the extruder for operation. To avoid blockage or interference with extrusion operations due to large material particles, motor one is started to drive the stirring rod and half gear to rotate. When the half gear contacts the toothed plate, it drives the toothed plate to slide along the guide rod and press the spring. At the same time, the toothed plate drives gear one to rotate, which in turn drives the crushing roller to rotate. When the half gear disengages from the toothed plate, the toothed plate returns to its original position under the spring's rebound, driving gear one and the crushing roller to reverse direction. This process is repeated. Furthermore, by using two sets of meshing gears, the auxiliary roller always rotates in the opposite direction when the crushing roller rotates. The crushing roller and auxiliary roller are used to crush the material, while the stirring rod is used to stir the crushed material to prevent blockage. By setting a feeding mechanism, only a single motor is needed to drive the crushing roller and auxiliary roller to rotate to crush the material, and also to drive the stirring rod to rotate to stir the material, thus avoiding blockage or interference with subsequent extrusion operations due to large material particles. This effectively improves the convenience of the equipment.

[0016] 2. In this utility model, by setting an auxiliary mechanism, during the rotation of the half gear and the reciprocating motion of the toothed plate, the cylinder and connecting rod structure drive the impact plate to slide up and down along the slide groove continuously, impacting the conveying pipe. At the same time, the two sets of impact blocks on the toothed plate impact the storage box and the discharge box respectively. The vibration further avoids material blockage. By setting an auxiliary mechanism, the impact of the impact plate and the two sets of impact blocks on the conveying pipe, storage box and discharge box respectively generates vibration, which further avoids material blockage and makes the material flow smoother, thus effectively improving the convenience of the equipment.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a wind power cable insulation layer extrusion device, including an extruder 1, a support 2, a storage box 3, a feeding box 4 and a feeding mechanism 5. The support 2 is disposed on one side of the extruder 1, the storage box 3 is fixedly connected to the surface of the support 2, the feeding box 4 is fixedly connected to the surface of the storage box 3, and the feeding mechanism 5 is disposed on the surface of the storage box 3.

[0025] The specific setup and function of its feeding mechanism 5 and auxiliary mechanism 6 will be explained below.

[0026] In this embodiment: the feeding mechanism 5 includes a motor 501, which is fixedly installed on the surface of the storage box 3. The output end of the motor 501 is fixedly connected to a stirring rod 502. A crushing roller 503 is rotatably connected to the inner wall of the feeding box 4. Guide rods 504 are fixedly connected to the surfaces of both the storage box 3 and the feeding box 4. A toothed plate 505 is slidably connected to the surface of the guide rod 504. A half gear 506 is fixedly connected to the surface of the stirring rod 502. The half gear 506 meshes with the surface of the toothed plate 505. A gear 507 is fixedly connected to the surface of the crushing roller 503. The gear 507 meshes with the surface of the toothed plate 505. A spring 508 is sleeved and connected to the surface of the guide rod 504.

[0027] The effects achieved by the above components are as follows: the starting motor 501 drives the stirring rod 502 and the half gear 506 to rotate. The guide rod 504, toothed plate 505, half gear 506 and spring 508 are set so that when the half gear 506 contacts the toothed plate 505, it drives the toothed plate 505 to slide along the guide rod 504 and press the spring 508. When the half gear 506 disengages from the toothed plate 505, the toothed plate 505 returns to its original position under the rebound action of the spring 508. This process is repeated. The guide rod 504 provides a limiting and guiding function for the movement of the toothed plate 505. The crushing roller 503 and gear 507 are set so that when the toothed plate 505 reciprocates, it can drive the gear 507 and the crushing roller 503 to continuously rotate in both directions.

[0028] Specifically, one end of the spring 508 is fixedly connected to the surface of the guide rod 504, and the other end of the spring 508 is fixedly connected to the surface of the toothed plate 505. The stirring rod 502 is rotatably connected to the inner wall of the storage box 3, and the stirring rod 502 is located inside the storage box 3.

[0029] The effects achieved by the above components are as follows: the spring 508 is set to facilitate the reset of the toothed plate 505, and works with the half gear 506 to realize the reciprocating motion of the toothed plate 505; the stirring rod 502 is set to facilitate the stirring of the crushed material, and avoid blockage or poor material discharge when entering the conveying pipe 7.

[0030] Specifically, an auxiliary roller 509 is rotatably connected to the inner wall of the feeding box 4, and gears 510 are fixedly connected to the surfaces of the crushing roller 503 and the auxiliary roller 509, with the two sets of gears 510 meshing with each other.

[0031] The effect achieved by the above components is as follows: the auxiliary roller 509 and gear 2 510 are set so that when the crushing roller 503 rotates, the two sets of gear 2 510 drive the auxiliary roller 509 to rotate in opposite directions.

[0032] Specifically, both the crushing roller 503 and the auxiliary roller 509 are located inside the feeding box 4, and the auxiliary roller 509 cooperates with the crushing roller 503.

[0033] The effect achieved by the above components is that the crushing roller 503 and the auxiliary roller 509 are set up to efficiently crush the material by using the crushing roller 503 and the auxiliary roller 509, which rotate in opposite directions and continuously rotate forward and backward.

[0034] Specifically, the surface of the support 2 is provided with an auxiliary mechanism 6, which includes a slide 61. The slide 61 is opened on the surface of the support 2. A bumper 62 is slidably connected to the surface of the slide 61. A cylinder 63 is fixedly connected to the surface of the half gear 506. A connecting rod 64 is rotatably connected to the surface of the cylinder 63. The end of the connecting rod 64 away from the cylinder 63 is rotatably connected to the surface of the bumper 62.

[0035] The effect achieved by the above components is as follows: the slide 61, the impact plate 62, the cylinder 63 and the connecting rod 64 are set so that when the half gear 506 rotates, the cylinder 63 and the connecting rod 64 drive the impact plate 62 to slide up and down along the slide 61 repeatedly, impacting the conveying pipe 7.

[0036] Specifically, the surface of the toothed plate 505 is fixedly connected with a striking block 65. There are two sets of striking blocks 65. One set of striking blocks 65 cooperates with the storage box 3, and the other set of striking blocks 65 cooperates with the feeding box 4.

[0037] The effect achieved by the above components is as follows: the two sets of impact blocks 65 are set so that when the toothed plate 505 reciprocates, it will impact the storage box 3 and the discharge box 4 respectively, using vibration to avoid material blockage and make the material flow smoother.

[0038] Specifically, a conveying pipe 7 is fixedly connected to the surface of the storage box 3. The end of the conveying pipe 7 away from the storage box 3 is fixedly connected to the surface of the extruder 1. A motor 8 is fixedly installed on the surface of the conveying pipe 7. A conveying auger 9 is fixedly connected to the output end of the motor 8. The conveying auger 9 is located inside the conveying pipe 7.

[0039] The effect achieved by the above components is that the starting motor 8 drives the conveying auger 9 to rotate, and in conjunction with the conveying pipe 7, it can continuously convey materials to the extruder 1, and it is not easy to cause blockage.

[0040] Working principle: By setting up the feeding mechanism 5, the material is put into the storage box 3 from the feeding box 4. When the material needs to be discharged, the second motor 8 is started to make the conveying auger 9 rotate, which, together with the conveying pipe 7, transports the material to the extruder 1 for operation. In order to avoid the material particles being too large and causing blockage or affecting the extrusion operation, the first motor 501 is started to drive the stirring rod 502 and the half gear 506 to rotate. When the half gear 506 contacts the toothed plate 505, it drives the toothed plate 505 to slide along the guide rod 504 and press the spring 508. At the same time, the toothed plate 505 drives the first gear 507 to rotate, which in turn makes the crushing roller 503 rotate. When the half gear 506 disengages from the toothed plate 505, the spring 508 rebounds. The toothed plate 505 resets, driving gear 1 507 and crushing roller 503 to reverse. This process repeats, and with the use of two sets of meshing gears 2 510, the auxiliary roller 509 always rotates in the opposite direction when the crushing roller 503 rotates. The crushing roller 503 and auxiliary roller 509 are used to crush the material, while the stirring rod 502 is used to stir the crushed material to prevent clogging. By setting up the feeding mechanism 5, only a single motor is needed to drive the crushing roller 503 and auxiliary roller 509 to rotate to crush the material, and also to drive the stirring rod 502 to rotate to stir the material. This avoids large material particles from causing clogging or affecting subsequent extrusion operations, thus effectively improving the convenience of the equipment.

[0041] Furthermore, by setting up an auxiliary mechanism 6, during the rotation of the half gear 506 and the reciprocating motion of the toothed plate 505, the cylinder 63 and connecting rod 64 structure drive the impact plate 62 to slide up and down along the slide groove 61 continuously, impacting the conveying pipe 7. At the same time, the two sets of impact blocks 65 on the toothed plate 505 impact the storage box 3 and the discharge box 4 respectively. The vibration further avoids material blockage. By setting up the auxiliary mechanism 6, the impact plate 62 and the two sets of impact blocks 65 impact the conveying pipe 7, storage box 3 and discharge box 4 respectively, generating vibration, further avoids material blockage and makes the material flow smoother, thus effectively improving the convenience of the equipment.
