Description

Technical Field

[0001] The invention relates to the technical field of wire cable production, and in particular to a wire cable processing extruder. Background Art

[0002] Cable is a general term for optical cables, electrical cables and other items. It is mainly used for connecting equipment, transmitting electricity and other purposes. The raw materials for manufacturing cables mainly include internal core wires and outer sheath structures. These raw materials are used to process sheath insulation and various specifications of wires into cables. Cables are widely used. They are not only used in daily life, but also play an important role in the power system, such as power transmission, information transmission, etc. Wire cables are widely used in all aspects of production and life. In the production process, an extruder is generally used to extrude the outer sheath structure around the wire;

[0003] At present, in the process of extrusion production of the outer sheath structure of the wire and cable, especially in the production of cables with multi-layer outer sheath structures, the die head is usually designed to have multiple groups of feeding cavities and cooling cavities inside, so that the wire can be coated with multiple layers of outer sheath when passing through the die head. Although it has the characteristics of small size, multiple cavities are integrated inside the die head, resulting in its structure being too complicated, high cost, and very inconvenient maintenance. The replacement cost is very high when blockage and wear occur, and the downtime maintenance takes a long time. At the same time, due to the use of a single die head structure design, the extruders must be installed very close to each other to ensure the short-distance connection between each extruder and the die head. If the extruders are arranged too close, it will affect the arrangement of the extruders, especially for the extruder unit with an external feeding component, the arrangement is very inconvenient. Therefore, a wire and cable processing extruder is proposed to use multi-die head series processing, optimize the die head configuration without affecting the production of multi-layer cables, simple structure, reduce the use and maintenance cost, and enable each group of extruder units to be arranged. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a wire cable processing extruder, which adopts multi-die series processing, optimizes the die head configuration without affecting the production of multi-clad cables, has a simple structure, reduces the cost of use and maintenance, and enables the groups of extruders to be arranged in an expanded manner.

[0005] The technical solution adopted by the present invention to solve the technical problem is a wire cable processing extruder, comprising an extruder body, an extrusion screw tube for material melting and extrusion is arranged on the top of the extruder body, a die head for wire cable outer sheath processing can be detachably connected to the discharge end of the extrusion screw tube, and a connecting plate is arranged at the feed end of the die head and connected to the discharge end of the extrusion screw tube through the connecting plate;

[0006] The die head is provided with an inner mold core inside, and a through cavity for the flow of conducting wires is opened in a horizontal direction inside the inner mold core. An annular cavity for feeding extruded material is arranged at the outer periphery of the through cavity inside the die head, and an injection groove connected with the inside of the annular cavity is opened on the top of the die head. The discharge end of the die head is provided with an end seat, and there are two end seats. A discharge pipe connected with the discharge end of the die head is inserted between the end seats. A slot corresponding to the specification of the end of the discharge pipe is opened at the end of the die head away from the end seat.

[0007] By adopting the above technical scheme, the discharge end of the die head is provided with an end seat and a discharge pipe structure, and the feed end of the die head is provided with a slot structure corresponding to the specification of the discharge pipe end. When the extrusion production of the wire cable is carried out, a suitable number of extruders are selected according to the number of outer sheath layers of the wire cable, and the die heads at the discharge end of the extruder are connected in series, so that the discharge pipe on the inner layer side of the outer sheath is inserted into the slot at the outer sheath production position, and the groups of die heads are connected and connected in series by connecting the flange and the end of the die head. Each group of extruder bodies extrude the corresponding outer sheath material, and the wire completes the coating, cooling and shaping of each layer of material in turn during the transportation process, and finally realizes the production of the wire cable.

[0008] Specifically, a feed pipe is integrally formed on the side of the connection plate surface away from the extruder body, and a feed groove connecting the discharge end of the extrusion spiral tube and the inside of the feed pipe is opened inside the connection plate, a sleeve is sleeved on the outer periphery of the feed pipe, and the end of the sleeve away from the feed pipe is connected to the side of the die head top close to the injection groove, a fixing plate is fixedly connected to the side of the connection plate surface facing the feed pipe, and a screw is threadedly connected to the inside of the fixing plate, and the fixing plate is connected to the end of the sleeve through the screw.

[0009] By adopting the above technical scheme, the connecting plate is used to connect with the discharge end of the extrusion screw tube, and the feed end of the die head is connected with the feed tube through the sleeve. Before connecting the groups of die heads in series, the screw is turned to drive the sleeve to slide along the outer periphery of the feed tube, so that the feed tube body is inserted into the sleeve, shortening the distance between the discharge end and the connecting plate, making it convenient to connect the discharge tubes together. After the connection is in place, the screw is turned in the opposite direction to make the sleeve slide along the outer periphery of the feed tube, driving the end of the discharge tube to move and insert into the slot, thereby realizing the connection processing between the die heads. It is flexible to use and easy to adjust, and can quickly connect different numbers of die heads according to different production needs.

[0010] Specifically, a fixing seat is fixedly connected horizontally between the end seats, a rotating shaft is embedded in the upper and lower ends of the fixing seat and a clamping ring is movably connected to the rotating shaft, the outer periphery of the feed pipe is located between the inner parts of the clamping ring to form a new type of heat dissipation ring sheet, a cooling cavity is opened between the clamping rings and the feed pipe runs through the cooling cavity.

[0011] By adopting the above technical scheme, according to the production requirements of different wire coating materials, the cooling temperature required for the cable coating layer is different due to the differences in different raw materials and production processes. After the wire is coated on the outer periphery of the cable inside the die head, it is transported along the discharge pipe. A heat dissipation ring and an adjustable clamping ring structure are provided on the outer periphery of the discharge pipe. When the cooling temperature requirement of the coating layer is not high, the clamping ring can be opened and spread out to both sides so that the heat dissipation ring is fully exposed. During the transportation inside the feed pipe, the heat dissipation ring is used for natural heat dissipation cooling treatment, or auxiliary heat dissipation equipment such as fans are added to achieve slow cooling during the transportation of the wires and cables, thereby reducing the cooling cost. When the cooling temperature requirement of the coating layer is high, the closed clamping ring can be rotated along the rotating shaft to dock and lock the docking plates. At this time, the cooling chamber forms a closed space, and cooling water is supplied through the water inlet pipe and discharged from the drain pipe. In conjunction with the external cooling water circulation supply equipment, the temperature of the outer periphery of the discharge pipe can be greatly reduced, the heat dissipation efficiency can be improved, and rapid and efficient cooling of the wires and cables during transportation can be achieved, thereby improving the cooling efficiency.

[0012] Specifically, a connecting flange is welded on one end of the outer periphery of the discharge pipe away from the die head, and a docking hole A is opened inside the connecting flange. A docking hole B corresponding to the position of the docking hole A is opened on the surface of the die head close to the slot.

[0013] By adopting the above technical solution, when the discharge pipe is docked with the die head, after the docking is in place, the connecting flange is fitted to the end of the die head, the docking hole A is aligned with the docking hole B, and the fastener is screwed into the connection to achieve the fastening docking of the connection.

[0014] Specifically, the outer periphery of the feed trough, the outer periphery of the feed pipe and the outer periphery of the sleeve are all covered with a heating module.

[0015] By adopting the above technical solution, the heating modules located at the periphery of the feed trough, the feed pipe and the sleeve can heat the internal materials during the material transportation process to avoid material agglomeration.

[0016] Specifically, a screw hole is provided inside the fixing plate and is connected to a screw rod through the screw hole. A connecting ring located inside the sleeve is installed at one end of the screw rod close to the sleeve.

[0017] By adopting the above technical solution, the screw can be screwed along the screw hole, and when the screw is screwed, the connecting ring can be driven to rotate inside the sleeve, thereby adjusting the position of the sleeve and the die head in the horizontal direction.

[0018] Specifically, a docking plate is welded to one end of the clamping ring away from the fixing seat, corresponding locking holes are opened inside the docking plate, and fastening bolts are detachably connected between the locking holes, and rubber pads are bonded to the connection between the clamping ring and the fixing seat and one side of the connecting surface of the clamping plate.

[0019] By adopting the above technical solution, after the docking plates are closed, the locking holes are aligned and the clamping rings can be fixed by screwing in the fastening bolts. The rubber pad structure can ensure the sealing of the connection between the clamping rings and avoid the problem of leakage in the cooling chamber.

[0020] Specifically, a water inlet pipe connected to the interior of the cooling chamber is installed at the bottom of the clamping ring located on the bottom side of the fixing seat, and a drain pipe connected to the interior of the cooling chamber is installed at the top of the clamping ring located on the top side of the fixing seat.

[0021] By adopting the above technical solution, cooling water is supplied through the water inlet pipe for liquid cooling treatment, and the used cooling water is discharged through the drain pipe.

[0023] (1) The wire and cable processing extruder described in the present invention, when performing extrusion production of wires and cables, selects a suitable number of extruders according to the number of outer sheath layers of the wires and cables, and connects the die heads at the discharge ends of the extruders in series, so that the discharge pipe on the inner layer side of the outer sheath is inserted into the slot at the outer sheath production position, and connects the groups of die heads in series by connecting the flange and the end of the die head. Each group of extruder bodies extrude the corresponding outer sheath material, and the wire is coated, cooled and shaped in turn during the conveying process, thereby finally realizing the production of wires and cables.

[0024] (2) The wire and cable processing extruder described in the present invention, before connecting the groups of die heads in series, turns the screw to drive the sleeve to slide along the outer circumference of the feed tube, so that the feed tube body is inserted into the sleeve, shortening the distance between the discharge end and the connecting plate, making it convenient to connect the discharge tubes together. After the connection is in place, the screw is turned in the opposite direction to make the sleeve slide along the outer circumference of the feed tube, driving the end of the discharge tube to move and insert into the slot, thereby realizing the connection processing between the die heads. The extruder is flexible to use and easy to adjust, and can quickly connect different numbers of die heads according to different production needs.

[0025] (3) In the wire and cable processing extruder described in the present invention, when the cooling temperature requirement of the coating layer is not high, the clamping ring can be opened and spread to both sides so that the heat dissipation ring plate is fully exposed. The heat dissipation ring plate is used for natural heat dissipation cooling during the transportation inside the feed pipe, or an auxiliary heat dissipation device such as a fan is added to achieve slow cooling during the transportation of the wire and cable, thereby reducing the cooling cost. When the cooling temperature requirement of the coating layer is high, the closed clamping ring can be rotated along the rotating shaft to dock and lock the docking plates. At this time, the cooling chamber forms a closed space, and cooling water is supplied through the water inlet pipe and discharged through the drain pipe. In combination with the external cooling water circulation supply device, the temperature of the outer periphery of the discharge pipe can be greatly reduced, the heat dissipation efficiency can be improved, and the fast and efficient cooling of the wire and cable during transportation can be achieved, thereby improving the cooling efficiency.

Each group of extruder bodies 1 extrude the corresponding outer sheath material, and the wire completes the coating, cooling and shaping of each layer of material in turn during the transportation process, and finally realizes the production of wire cables.

[0039] Specifically, a feed pipe 402 is integrally formed on the side of the surface of the connecting disk 4 away from the extruder body 1, and a feed groove 401 is opened inside the connecting disk 4 to connect the discharge end of the extrusion spiral tube 2 and the inside of the feed pipe 402. A sleeve 403 is sleeved on the outer periphery of the feed pipe 402, and the end of the sleeve 403 away from the feed pipe 402 is connected to the top of the die head 3 near the injection groove 304.

[0042] When in use, according to the production requirements of different wire coating materials, the cooling temperature required for the cable coating layer is different due to the differences in different raw materials and production processes. After the wire is coated on the outer periphery of the cable inside the die head 3, it is transported along the discharge pipe 306. The outer periphery of the discharge pipe 306 is provided with a heat dissipation ring sheet 503 and an adjustable clamping ring 502 structure. When the cooling temperature requirement of the coating layer is not high, the clamping ring 502 can be opened and spread out to both sides to fully expose the heat dissipation ring sheet 503.

[0064] Specifically, the outer periphery of the feed trough 401 , the outer periphery of the feed pipe 402 and the outer periphery of the sleeve 403 are all covered with a heating module 404 .

[0065] When in use, the heating module 404 located at the outer periphery of the feeding trough 401, the feeding pipe 402 and the sleeve 403 can heat the internal material during the material transportation process to avoid material agglomeration.

[0066] Specifically, a screw hole 406 is opened inside the fixing plate 405 and is connected to a screw rod 407 through the screw hole 406 . A connecting ring 408 located inside the sleeve 403 is installed at one end of the screw rod 407 close to the sleeve 403 .

[0067] When in use, the screw rod 407 can be screwed along the screw hole 406 , and when the screw rod 407 is screwed, the connecting ring 408 can be driven to rotate inside the sleeve 403 , thereby adjusting the position of the sleeve 403 and the die head 3 in the horizontal direction.

[0068] Specifically, a docking plate 505 is welded to one end of the retaining ring 502 away from the fixing seat 5, corresponding locking holes 507 are opened inside the docking plate 505, and fastening bolts 508 are detachably connected between the locking holes 507, and rubber pads 506 are bonded to the connection between the retaining ring 502 and the fixing seat 5 and one side of the connecting surface of the retaining plate.

[0069] When in use, after the docking plate 505 is closed, the locking holes 507 are aligned, and the fastening bolts 508 are screwed in to fix the clamping rings 502. The rubber pad 506 structure can ensure the sealing of the connection between the clamping rings 502 to avoid leakage of the cooling chamber 504.

[0070] Specifically, a water inlet pipe 509 connected to the interior of the cooling chamber 504 is installed at the bottom of the clamping ring 502 located at the bottom side of the fixing seat 5, and a drain pipe 510 connected to the interior of the cooling chamber 504 is installed at the top of the clamping ring 502 located at the top side of the fixing seat 5.

[0071] When in use, cooling water is supplied through the water inlet pipe 509 for liquid cooling treatment, and the used cooling water is discharged through the drain pipe 510.

[0072] When in use, during the extrusion production of wire cables, a suitable number of extruders are selected according to the number of outer sheath layers of the wire cables, and the die heads 3 at the discharge ends of the extruders are connected in series, so that the discharge pipe 306 on the inner layer side of the outer sheath is inserted into the slot 309 at the outer sheath production position, and the groups of die heads 3 are connected in series by connecting the flange 307 and the end of the die head 3. Each group of extruder bodies 1 extrude the corresponding outer sheath material, and the wire completes the coating, cooling and shaping of each layer of material in turn during the transportation process, and finally realizes the production of wire cables. Before connecting the groups of die heads 3 in series, the screw 407 is turned to drive the sleeve 403 to slide along the outer periphery of the feed pipe 402, so that the main body of the feed pipe 402 is inserted into the sleeve 403, shortening the distance between the discharge end and the connecting plate 4, and facilitating the connection of the discharge pipe 306. The two dies 3 are butt-jointed together. After the butt-jointed is in place, the screw 407 is turned in the opposite direction, so that the sleeve 403 can slide along the outer periphery of the feed pipe 402, drive the end of the discharge pipe 306 to move and insert it into the slot 309, so as to realize the butt-jointing between the die heads 3. The die heads 3 are flexible to use and easy to adjust. Different numbers of die heads 3 can be quickly butt-jointed according to different production requirements. When the cooling temperature of the coating layer is required to be high, the closed clamp ring 502 can be rotated along the rotating shaft 501 to butt and lock the butt-jointed plates 505. At this time, the cooling chamber 504 forms a closed space, and cooling water is supplied through the water inlet pipe 509 and discharged through the drain pipe 510. In combination with the external cooling water circulation supply equipment, the temperature of the outer periphery of the discharge pipe 306 can be greatly reduced, the heat dissipation efficiency can be improved, and the fast and efficient cooling of the wire and cable during transportation can be realized, thereby improving the cooling efficiency.
