Description

Technical Field

[0001] This utility model relates to the field of extrusion equipment technology, specifically to an extrusion device for producing overhead insulated wires that is easy to feed. Background Technology

[0002] Overhead insulated conductors are overhead conductors equipped with insulation layers and protective outer sheaths. They are a special type of cable manufactured using a process similar to that of cross-linked cables. They represent a new power transmission method between overhead conductors and underground cables. During the production of overhead insulated conductors, they require extrusion molding using an extrusion device.

[0003] In existing technology, the extrusion principle during the production of overhead insulated conductors is as follows: First, the raw material for the overhead insulated conductor enters the barrel from the hopper. Under the thrust of the rotating screw, it is continuously propelled forward. Simultaneously, the heating device outside the barrel heats the raw material. The stirring and extrusion action of the screw, as well as the shear friction between the plastic and the equipment, also generate heat, causing the raw material to gradually transform from a solid state to a viscous flow state, forming a continuous and uniform material flow. Then, the plasticized melt of the overhead insulated conductor is further pushed by the screw and fed into the die head. The material is extruded through the annular gap between the die core and the die sleeve, and extruded around the conductor or wire core to form a continuous and dense insulation layer. Finally, the extruded wire with the insulation layer enters the cooling device, where it exchanges heat with cooling media such as cooling water. The temperature of the insulation layer drops rapidly, changing from a plastic state to a shaped solid state, thus completing the extrusion production of overhead insulated wires. However, the hopper of current extrusion equipment is usually high, and manual feeding requires the use of external tools, which is not convenient for continuous quantitative feeding and can easily affect the extrusion efficiency during the production of overhead insulated wires.

[0041] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0042] like Figures 1-6As shown, this embodiment proposes an extrusion device for producing overhead insulated wires that facilitates material feeding. It includes an extruder body 1 with a feed hopper 2 connected to it. The extruder body 1 is a common extruder, consisting of a barrel, screw, and die head. After the overhead insulated wire material enters the barrel from the hopper, it is continuously propelled forward by the thrust of the rotating screw. Simultaneously, a heating device outside the barrel heats the material. The stirring and extrusion action of the screw, as well as the shear friction between the plastic and the equipment, also generate heat, causing the overhead insulated wire material to gradually transform from a solid state to a viscous flow state, forming a continuous and uniform material flow. The plasticized overhead insulated conductor melt is fed into the die head under the continued push of the screw. The overhead insulated conductor melt is extruded from the die sleeve through the annular gap between the die core and the die sleeve, extruding around the conductor or wire core to form a continuous and dense insulation layer. Finally, the extruded conductor with the insulation layer enters the cooling device. Through heat exchange with cooling water and other cooling media, the temperature of the insulation layer drops rapidly, changing from a plastic state to a shaped solid state, completing the extrusion production of the overhead insulated conductor. The system also includes a feeding cylinder 3, feeding assembly, metering box 4, unloading hopper 5, metering port, separator plate 6, metering plate 7, metering assembly, and discharge pipe 8. 3 is inclinedly set on one side of the extruder body 1. The feeding assembly is installed inside the feeding cylinder 3. The metering box 4 is connected through to one side of the feeding cylinder 3. The unloading hopper 5 is fixedly connected to the inner wall of the metering box 4. Two metering ports are provided, which are symmetrically opened on the unloading hopper 5 to facilitate the metering input of overhead insulated wire raw materials. The partition plate 6 is fixedly connected between the unloading hopper 5 and the metering box 4. Two metering plates 7 are provided. The two metering plates 7 are respectively movable and rotatable and set under the two metering ports. Anti-wear pads 26 are fixedly connected to both metering plates 7 to reduce the collision and wear between the metering plates 7 and the unloading hopper 5. When it is necessary to adjust the metering box 4 When storing the raw materials for overhead insulated wire production in the machine, two metering plates 7 are located directly below the two metering ports to block them. The metering component is set between the two metering plates 7. The discharge pipe 8 is connected to one side of the feeding cylinder 3, and the discharge end of the discharge pipe 8 is located inside the feeding hopper 2, which allows the raw materials for overhead insulated wire to enter the extruder body 1. Two metering hoppers 21 are symmetrically connected to the top of the metering box 4, which facilitates the uniform feeding of the raw materials for overhead insulated wire production into the metering box 4. Two fixing plates are symmetrically connected to the bottom of the metering box 4. Both fixing plates are fixedly connected to the extruder body 1, which can stably support the metering box 4.

[0043] refer to Figure 3 , Figure 4 as well as Figure 5The metering assembly includes a connecting frame 9, an electric push rod 10, a connecting cylinder 11, a first motor 12, a connecting rod 13, and a shaped stirring rod 14. The connecting frame 9 is fixedly connected to the top of the metering box 4. The electric push rod 10 is mounted on the connecting frame 9, and its output end is connected through the connecting frame 9. The connecting cylinder 11 is fixedly connected to the output end of the electric push rod 10. Two limiting frames 25 are symmetrically connected to the connecting cylinder 11. The connecting frame 9 has limiting grooves for the limiting frames 25 to rotate, which can control the rotation of the connecting cylinder 4. The sliding of the connecting cylinder 11 is limited so that the connecting cylinder 11 drives the first motor 12 to move stably. The first motor 12 is installed on the connecting cylinder 11. The connecting rod 13 is fixedly connected between the output end of the motor and the two metering plates 7. The partition plate 6 has a rotation port for the connecting rod 13 to rotate. The partition plate 6 is fixedly connected with an anti-wear strip so that the connecting rod 13 can rotate stably in the rotation port. Multiple irregular stirring rods 14 are provided, and multiple irregular stirring rods 14 are fixedly connected to the connecting rod 13.

[0044] When it is necessary to quantitatively feed the raw materials for overhead insulated conductor production, the electric push rod 10 is activated, causing the connecting cylinder 11 to drive the first motor 12 to move. This allows the first motor 12 to drive the connecting rod 13 and the two metering plates 7 to move, moving the metering plates 7 away from the metering port and exposing the metering port. Simultaneously, the first motor 12 is activated, causing the first motor 12 to drive the connecting rod 13 to rotate. This allows the connecting rod 13 to drive the two metering plates 7 and multiple irregularly shaped stirring rods 14 to rotate. When the metering plates 7 rotate, the exposure angle of the metering port is adjusted, thus ensuring stable feeding of the raw materials for overhead insulated conductor production. At the same time, the rotation of the multiple irregularly shaped stirring rods 14 thoroughly mixes the various raw materials for overhead insulated conductor production, thereby improving the extrusion effect of the raw materials for overhead insulated conductor production.

[0045] refer to Figure 6 The feeding assembly includes a second motor 15, a feeding column 16, and a feeding spiral blade 17. The second motor 15 is installed on one side of the feeding cylinder 3. The feeding column 16 is fixedly connected to the output end of the second motor 15, and the feeding column 16 is rotatably connected to the feeding cylinder 3. The feeding spiral blade 17 is fixedly connected to the feeding column 16.

[0046] When the raw materials for overhead insulated wire production enter the feeding cylinder 3 through the quantitative box 4, the second motor 15 is started, causing the feeding column 16 to drive the feeding spiral blade 17 to rotate. This allows the feeding spiral blade 17 to push the raw materials for overhead insulated wire production, thereby ensuring that the raw materials for overhead insulated wire production continuously and evenly enter the discharge pipe 8 and the feed hopper 2.

[0047] refer to Figure 1 as well as Figure 2A positioning ring 18 is fitted on the discharge pipe 8. A positioning pad 19 is fixedly connected to the positioning ring 18. The positioning pad 19 has a through-hole that matches the discharge pipe 8. Two positioning frames 20 are symmetrically connected to the positioning ring 18. A support rod 22 and a support frame 23 are fixedly connected to the bottom of the feeding cylinder 3 and the extruder body 1, respectively. A base plate 24 is fixedly connected between the support rod 22 and the support frame 23. Both positioning frames 20 are fixedly connected to the base plate 24, which can stably support the feeding cylinder 3, the extruder body 1 and the positioning ring 18.

[0048] The two positioning frames 20 can stably support the positioning ring 18, so that the positioning ring 18 can stably support the discharge pipe 8. When the raw material for producing overhead insulated wires enters the feed hopper 2 through the discharge pipe 8, the positioning ring 18 and the positioning pad 19 can provide elastic support for the discharge pipe 8, reducing the shaking of the discharge pipe 8 when discharging, so that the raw material for producing overhead insulated wires can stably enter the feed hopper 2.

[0049] In this embodiment, firstly, various raw materials for producing overhead insulated wires are evenly fed into the metering box 4 through two metering hoppers 21. Then, the electric push rod 10 is started, causing the connecting cylinder 11 to drive the first motor 12, connecting rod 13, and metering plate 7 to move. Simultaneously, the first motor 12 is started, causing the connecting rod 13, the two metering plates 7, and multiple irregularly shaped stirring rods 14 to rotate. When the two metering plates 7 rotate, the two metering ports can be exposed at multiple angles, thus allowing for continuous and even metering of the raw materials for producing overhead insulated wires. Then, the second motor 15 is started, causing the feeding column 16 to drive the feeding spiral blade 17 to rotate. The feeding spiral blade 17 pushes the raw materials for producing overhead insulated wires, so that the raw materials for producing overhead insulated wires will enter the extruder body 1 through the discharge pipe 8 and the feed hopper 2. Then, the raw materials for producing overhead insulated wires are extruded.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
