Description

Technical Field

[0001] This utility model relates to the field of cable extruder technology, and in particular to an extruder for cable processing. Background Technology

[0002] Cables are a common item in our lives. The main function of cables is to transmit electricity to various power towers, and then to residential users. During the manufacturing process, cables must have good physical properties to avoid damage. Therefore, a rubber-like protective layer is attached to the outer layer of the cable. This requires the use of an extruder to manufacture the protective layer by melting it at high temperature and then extruding it through a mold.

[0003] However, in the current technology, cables are diverse and require protective layers of different sizes. Therefore, different models of extrusion heads need to be replaced. The extrusion heads of existing cable processing extruders are fixed with bolts, which requires frequent disassembly and tightening of bolts. Not only is the replacement process cumbersome, but over time it may even cause the bolt threads to strip, resulting in unstable installation of the extrusion head and affecting production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an extruder for cable processing, comprising: a base plate, a control terminal provided on the top surface of the base plate, support frames fixedly installed on both sides of the top surface of the base plate, an extruder body fixedly installed on the inner wall surfaces of the two support frames, a discharge port fixedly connected to one side surface of the extruder body, a feeding port fixedly connected to the outer wall surface of the extruder body, a fixing component provided on one side of the top surface of the base plate, screening components provided on the inner wall surfaces of both sides of the feeding port, the fixing component comprising two long plates, the two long plates being symmetrically fixedly installed on one side of the top surface of the base plate, a bidirectional threaded rod connected between the two long plates via a bearing, a forward and reverse motor fixedly installed on one side surface of one of the long plates, the output end of the forward and reverse motor being fixedly connected to one end surface of the bidirectional threaded rod.

[0006] In a preferred embodiment, a long rod is fixedly installed between the two long plates. Two movable plates are threadedly connected to the surface of the bidirectional threaded rod. One end of each of the two movable plates is movably sleeved on the surface of the long rod, and the two movable plates slide with the help of the bidirectional threaded rod and the long rod.

[0007] In a preferred embodiment, clamping members are fixedly installed on one side surface of both movable plates, and a fixing ring is movably clamped between the two clamping members. An extrusion head is fixedly installed on the inner wall surface of the fixing ring.

[0008] In a preferred embodiment, a plurality of mounting grooves are provided on one side surface of the extrusion head, and a plurality of mounting plates are fixedly mounted on the outer wall surface of the discharge port, the plurality of mounting plates being located inside the plurality of mounting grooves.

[0009] In a preferred embodiment, the screening assembly includes two first through slots, which are formed on the inner wall surfaces at both ends of the feed port. An L-shaped plate is slidably connected to the inside of each of the two first through slots, and a screening screen is fixedly installed between the two L-shaped plates.

[0010] In a preferred embodiment, a second through groove is provided on one side surface of the feeding port, and an extension plate is fixedly installed on one side surface of one of the L-shaped plates, with the end of the extension plate away from one of the L-shaped plates passing through the second through groove.

[0011] In a preferred embodiment, a rotating motor is fixedly installed on one side surface of the feeding port, a short plate is fixedly installed at the output end of the rotating motor, an extension rod is fixedly installed at one end of one side surface of the short plate, a connecting plate is sleeved on the surface of the extension rod through a bearing, and the end of the connecting plate away from the extension rod is hinged to the bottom surface of the extension plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, when it is necessary to replace the extruder head, the forward and reverse motors are first operated by the control terminal. The operation of the forward and reverse motors drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod drives two movable plates to move in opposite directions on the surface of the long rod. The movement of the two movable plates in opposite directions on the surface of the long rod drives two clamping members to move in opposite directions. When the two clamping members disengage from the fixing ring, the extruder head loses its limit. At this time, the extrusion ring can be pulled to disengage multiple mounting plates from multiple mounting slots on the surface of the discharge port, thus disassembling the extruder head. Then, the multiple mounting slots of the new extruder head are aligned with the multiple mounting plates and re-inserted. At this time, the forward and reverse motors are operated in reverse, so that the two clamping members clamp the fixing ring again to limit the position, thereby completing the purpose of disassembling and replacing the extruder head. Through the cooperation of the above structure, the two clamping members can firmly clamp and sleeve the extruder head on the discharge port of the extruder without the need for bolt fixing. The operation is simple and can ensure the stable installation of the extruder head, indirectly improving the production efficiency of the cable extruder.

[0014] 2. In this utility model, when materials need to be screened, the materials are first added to the surface of the screening screen through the feeding port. Then, the control terminal runs a rotating motor, which drives the short plate to rotate. The short plate rotates, which in turn drives the extension rod to rotate. The extension rod rotates, which in turn moves the connecting plate. The connecting plate moves, which in turn moves the extension plate back and forth inside the second through groove. The screening screen is connected between the two L-shaped plates. The reciprocating movement of the extension plate inside the second through groove drives the two L-shaped plates to reciprocate inside the two first through grooves. The reciprocating movement of the two L-shaped plates drives the screening screen to reciprocate. The reciprocating movement of the screening screen screen screens the materials on its surface. Through the cooperation of the above structure, the screening screen screen can move back and forth, which speeds up the screening of the materials on the screen screen surface and prevents the materials from clumping due to long-term storage and being unable to be softened by the extruder body, thus blocking the discharge port.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-8 This utility model provides a technical solution: an extruder for cable processing, comprising: a base plate 1, a control terminal 2 on the top surface of the base plate 1, support frames 3 fixedly installed on both sides of the top surface of the base plate 1, an extruder body 4 fixedly installed on the inner wall surface of the two support frames 3, a discharge port 5 fixedly connected to one side surface of the extruder body 4, a feeding port 6 fixedly connected to the outer wall surface of the extruder body 4, a fixing component 7 on one side of the top surface of the base plate 1, screening components 8 on both sides of the inner wall surface of the feeding port 6, the fixing component 7 comprising two long plates 701, the two long plates 701 being symmetrically fixedly installed on one side of the top surface of the base plate 1, a bidirectional threaded rod 702 connected between the two long plates 701 by a bearing, a forward and reverse motor 703 fixedly installed on one side surface of one of the long plates 701, the output end of the forward and reverse motor 703 being fixedly connected to one end surface of the bidirectional threaded rod 702.

[0027] Specifically: Control terminal 2 controls the operation of forward and reverse motor 703 and rotary motor 806, and forward and reverse motor 703 controls the forward and reverse rotation of bidirectional threaded rod 702.

[0028] In one embodiment, a long rod 704 is fixedly installed between two long plates 701. Two movable plates 705 are threadedly connected to the surface of the bidirectional threaded rod 702. One end of each movable plate 705 is movably sleeved on the surface of the long rod 704. The two movable plates 705 slide with the help of the bidirectional threaded rod 702 and the long rod 704.

[0029] Specifically: the two movable plates 705 slide with the help of the bidirectional threaded rod 702 and the long rod 704. The bidirectional threaded rod 702 drives the two movable plates 705 to slide in opposite directions on the surface of the long rod 704.

[0030] In one embodiment, clamping members 706 are fixedly installed on one side surface of both movable plates 705, and a fixing ring 707 is movably clamped between the two clamping members 706. An extrusion head 708 is fixedly installed on the inner wall surface of the fixing ring 707.

[0031] Specifically: The inner walls of the two clamping members 706 are provided with arc-shaped grooves, and the fixing ring 707 is clamped inside the two arc-shaped grooves by the two clamping members 706, thereby clamping and limiting the extrusion head 708.

[0032] In one embodiment, a plurality of mounting grooves 710 are provided on one side surface of the extruder head 708, and a plurality of mounting plates 709 are fixedly mounted on the outer wall surface of the discharge port 5, with the plurality of mounting plates 709 located inside the plurality of mounting grooves 710.

[0033] Specifically: the extruder 708 is movably mounted on the discharge port 5 via the mounting groove 710 and the mounting plate 709. The mounting plate 709 and the mounting groove 710 limit the rotation of the extruder 708 and ensure that the extruder 708 is stably installed.

[0034] In one embodiment, the screening component 8 includes two first through slots 801, which are formed on the inner wall surfaces at both ends of the feed port 6. L-shaped plates 802 are slidably connected to the interior of each of the two first through slots 801, and a screening screen 803 is fixedly installed between the two L-shaped plates 802.

[0035] Specifically: the screening mesh 803 plays the role of screening agglomerated materials. The two L-shaped plates 802 are attached to the two first through grooves 801 on both sides, so that the screening mesh 803 can sway left and right.

[0036] In one embodiment, a second through groove 804 is provided on one side surface of the feeding port 6, and an extension plate 805 is fixedly installed on one side surface of one of the L-shaped plates 802. The end of the extension plate 805 away from one of the L-shaped plates 802 passes through the second through groove 804.

[0037] Specifically, the L-shaped plate 802 serves to drive the two L-shaped plates 802 to slide inside the two first through slots 801.

[0038] In one embodiment, a rotary motor 806 is fixedly installed on one side surface of the feeding port 6, a short plate 807 is fixedly installed at the output end of the rotary motor 806, an extension rod 808 is fixedly installed at one end of one side surface of the short plate 807, and a connecting plate 809 is sleeved on the surface of the extension rod 808 through a bearing. The end of the connecting plate 809 away from the extension rod 808 is hinged to the bottom surface of the extension plate 805.

[0039] Specifically: the rotating motor 806 drives the short plate 807 to rotate, and the rotation of the short plate 807 drives the connecting plate 809 to move back and forth, thereby enabling the extension rod 808 to move back and forth.

[0040] Working Principle: This device requires different extrusion heads 708 depending on the cable being processed. When the extrusion head 708 needs to be changed, the control terminal 2 first operates the forward and reverse motor 703. The forward and reverse motor 703 drives the bidirectional threaded rod 702 to rotate. The rotation of the bidirectional threaded rod 702 causes two movable plates 705 to move in opposite directions on the surface of the long rod 704. The movement of the two movable plates 705 in opposite directions on the surface of the long rod 704 causes two clamping members 706 to move in opposite directions. When the two clamping members 706 disengage from the fixing ring 707... When the extrusion head 708 is released from its limit position, the extrusion ring can be pulled to disengage the multiple mounting plates 709 from the multiple mounting slots 710 on the surface of the discharge port 5, thus removing the extrusion head 708. Then, the multiple mounting slots 710 where a new extrusion head 708 is needed are aligned with the multiple mounting plates 709 and re-inserted. At this point, the forward and reverse motors 703 are reversed, causing the two clamping members 706 to clamp and limit the fixing ring 707 again, thereby completing the purpose of disassembling and replacing the extrusion head 708. Through the cooperation of the above structure, the two clamping members 706 can firmly clamp and mount the extrusion head 708 onto the extruder. No bolts are needed for fixing at the discharge port 5, making operation simple and ensuring stable installation of the extruder head 708, indirectly improving the production efficiency of the cable extruder. When materials need to be screened, the material is first added to the surface of the screening screen 803 through the feeding port 6. Then, the control terminal 2 runs the rotating motor 806, which drives the short plate 807 to rotate. The rotation of the short plate 807 drives the extension rod 808 to rotate, which in turn drives the connecting plate 809 to move. The movement of the connecting plate 809 causes the extension plate 805 to reciprocate inside the second through groove 804. The two L... A screening screen 803 is connected between the plates 802. The extension plate 805 moves back and forth inside the second through groove 804, thereby driving the two L-shaped plates 802 to move back and forth inside the two first through grooves 801. The reciprocating movement of the two L-shaped plates 802 drives the screening screen 803 to move back and forth. The reciprocating movement of the screening screen 803 thereby screens the material on the surface of the screening screen 803. Through the cooperation of the above structure, the screening screen 803 can move back and forth left and right, speeding up the screening of the material on the surface of the screening screen 803, and preventing the material from clumping due to long-term storage and being unable to be softened by the extruder body 4, thus blocking the discharge port 5.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
