Description

Technical Field

[0001] This utility model relates to the field of power cable technology, and more specifically, to a plastic extruder for cable processing. Background Technology

[0002] Cables are typically rope-like structures made of several or groups of conductors (at least two conductors per group) twisted together. Each group of conductors is insulated from the others and is often twisted around a central conductor. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being internally energized and externally insulated.

[0003] The outer layer of a cable, usually called the outer sheath, is an important part of the cable structure. When the outer layer of a cable needs to be processed, plastic granules are heated and extruded using a plastic extruder.

[0004] A typical plastic extruder mainly uses the rotation of a screw to push heated and molten material towards the die head, and then extrude it through a mold to form a shape. Specifically, after solid plastic is heated to a liquid state, it is continuously extruded from the die head by the pushing action of the screw, and then cooled and shaped by the outside. However, when plastic granules are poured into the inside of the device, many large impurities will enter the inside of the device along with the plastic granules. This will result in impurities in the processed plastic, so it is necessary to modify and optimize the device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a plastic extruder for cable processing, which has the advantages of avoiding many impurities and being easy to clean.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic extruder for cable processing, comprising a bottom column and a bottom plate, wherein the bottom plate is fixedly disposed above the bottom column;

[0007] A heating chamber is fixedly installed above the base plate, and a screening chamber is fixedly installed above the heating chamber. A support mechanism is fixedly installed on one side of the screening chamber, and a motor is fixedly installed on one side of the support mechanism. A rotating plate is fixedly installed above the drive shaft of the motor. A protrusion is fixedly installed on one side of the rotating plate. A movable frame is movably sleeved on the outside of the protrusion. Connecting blocks are fixedly installed on some parts of the movable frame. One end of the connecting block extends into the interior of the screening chamber and is fixedly installed with a screen. The screen is movably connected to the screening chamber.

[0008] As a preferred technical solution of this utility model, a limiting frame is fixedly installed on the top of the base plate, a second gear is fixedly installed on one side of the limiting frame, a threaded rod is fixedly installed on one side of the second gear, one end of the threaded rod extends into the interior of the limiting frame, a threaded block is threadedly sleeved on the outer surface of the threaded rod, and the top of the threaded block extends to the top of the limiting frame.

[0009] As a preferred embodiment of this utility model, the support mechanism includes a pillar fixedly disposed on one side of the screening chamber, a fixing plate fixedly installed on one side of the pillar, and a fixing plate fixedly connected to a motor on one side.

[0010] As a preferred embodiment of this utility model, a motor is fixedly installed on the top of the base plate, and a gear is fixedly installed on the top of the transmission shaft of the motor, with the gear meshing with the gear.

[0011] As a preferred embodiment of this utility model, a second motor is fixedly installed above the threaded block, and a connecting rod is fixedly installed above the drive shaft of the second motor. One end of the connecting rod extends into the interior of the heating chamber and is fixedly installed with an auger.

[0012] As a preferred embodiment of this utility model, a baffle is fixedly sleeved on the outer surface of the connecting rod, and the baffle is located inside the heating chamber.

[0013] As a preferred embodiment of this utility model, a feed inlet is provided above the heating chamber, and the feed inlet is connected to the interior of the screening chamber.

[0014] As a preferred embodiment of this utility model, the heating chamber is internally threaded with a sealing threaded cover, one end of which extends to the outside of the heating chamber.

[0015] As a preferred embodiment of this utility model, a handle is fixedly installed on one side of the sealing threaded cover, and a discharge pipe is provided on one side of the sealing threaded cover, the discharge pipe being connected to the interior of the heating chamber.

[0016] As a preferred embodiment of this utility model, a heating plate is fixedly sleeved inside the heating chamber, and the heating plate is located outside the feed inlet.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model uses a controller to start a motor to drive a rotating plate to rotate, which in turn drives the protrusion to move in a circular motion. The movement of the protrusion is restricted by the screen, causing the moving frame to move in a reciprocating linear motion. This causes the connecting block and the screen to move synchronously, thus achieving the screening of impurities above the screen. Compared with traditional devices, this device screens impurities by moving the screen back and forth, avoiding the generation of impurities inside the processed plastic, which would affect the use of the cable, thereby improving the working efficiency of the device.

[0019] 2. This utility model allows the sealing threaded cover to be removed by rotating the handle. Starting the controller motor drives gear one to rotate. Through the meshing of gear one and gear two, the threaded rod is driven, causing the threaded block to move. This, in turn, drives motor two to push the auger forward. Once the auger is out of the heating chamber, motor one is turned off, allowing the auger surface to be cleaned. Compared to traditional devices, this device facilitates cleaning the auger by removing it from the heating chamber, preventing the plastic casing of another type of cable from remaining on the auger surface and affecting production, thus improving the device's efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] like Figures 1 to 8 As shown, this utility model provides a plastic extruder for cable processing, including a bottom column 1 and a bottom plate 2, with the bottom plate 2 fixedly disposed above the bottom column 1;

[0031] A heating chamber 3 is fixedly installed above the base plate 2. A screening chamber 18 is fixedly installed above the heating chamber 3. A support mechanism is fixedly installed on one side of the screening chamber 18. A motor 20 is fixedly installed on one side of the support mechanism. A rotating plate 21 is fixedly installed above the drive shaft of the motor 20. A protrusion 22 is fixedly installed on one side of the rotating plate 21. A movable frame 23 is movably sleeved on the outside of the protrusion 22. A connecting block 24 is fixedly installed on some parts of the movable frame 23. One end of the connecting block 24 extends into the interior of the screening chamber 18 and a screen 25 is fixedly installed thereon. The screen 25 is movably connected to the screening chamber 18.

[0032] When the operator uses the device, they first start the motor 20 via the controller. Once the motor 20 starts, it drives the rotating plate 21 to rotate. When the rotating plate 21 rotates, it drives the protrusion 22 to make a circular motion. When the protrusion 22 makes a circular motion, the rotation of the moving frame 23 is restricted by the screen 25. Therefore, as the protrusion 22 rotates, it drives the moving frame 23 to make a reciprocating linear motion. When the moving frame 23 makes a reciprocating linear motion, it drives the connecting block 24 to make a reciprocating linear motion, thereby driving the screen 25 to make a reciprocating linear motion, thus screening the impurities above the screen 25.

[0033] The controller starts the motor 20, which drives the rotating plate 21 to rotate, thereby driving the protrusion 22 to move in a circular motion. The movement of the protrusion 22 is restricted by the screen 25, causing the moving frame 23 to reciprocate in a linear motion. This causes the connecting block 24 and the screen 25 to move synchronously, thus screening impurities above the screen 25. Compared with traditional devices, this device screens impurities by moving the screen 25 back and forth, avoiding the generation of impurities inside the processed plastic, which would affect the use of the cable, thereby improving the working efficiency of the device.

[0034] Among them, a limiting frame 4 is fixedly installed on the top of the base plate 2, a gear 7 is fixedly installed on one side of the limiting frame 4, a threaded rod 8 is fixedly installed on one side of the gear 7, one end of the threaded rod 8 extends into the interior of the limiting frame 4, a threaded block 9 is threadedly sleeved on the outer surface of the threaded rod 8, and the top of the threaded block 9 extends to the top of the limiting frame 4.

[0035] When the operator uses the device, they first hold handle 16 and rotate the sealing threaded cover 15 to remove it from the heating chamber 3. Then, they start motor 5 via the controller. When motor 5 starts, it drives gear 6 to rotate. As gear 6 rotates, it meshes with gear 7, causing gear 7 to rotate. When gear 7 rotates, it drives threaded rod 8 to rotate. As threaded rod 8 rotates, it moves threaded block 9 because of the threaded connection between threaded block 9 and threaded rod 8. When threaded block 9 moves, it drives motor 10 to move, thus pushing auger 12 forward. When auger 12 is completely removed from the heating chamber 3, motor 5 can be turned off.

[0036] By rotating the sealing threaded cover 15 by holding the handle 16, the controller motor 5 is started, driving the gear 6 to rotate. Through the meshing of gear 6 and gear 7, the threaded rod 8 is driven, causing the threaded block 9 to move. This, in turn, drives the motor 10 to push the auger 12 forward. After the auger 12 moves out of the heating chamber 3, the motor 5 is turned off, and the surface of the auger 12 can be cleaned. Compared with the traditional device, this device, by moving the auger 12 out of the heating chamber 3, facilitates the cleaning of the auger 12 and avoids leaving the plastic shell of another type of cable on the surface of the auger 12 when producing it, thus affecting production and improving the working efficiency of the device.

[0037] The support mechanism includes a pillar 27 fixedly installed on one side of the screening chamber 18, a fixing plate 19 fixedly installed on one side of the pillar 27, and a fixing plate 19 fixedly connected to a motor 20 on one side of the fixing plate 19.

[0038] The design of the support column 27 and the fixing plate 19 supports the position of the motor 3 20, thereby improving the stability of the motor 3 20 during operation.

[0039] Among them, a motor 5 is fixedly installed on the top of the base plate 2, and a gear 6 is fixedly installed on the top of the drive shaft of the motor 5. The gear 6 meshes with the gear 7.

[0040] The controller starts motor 5, which drives gear 6 to rotate, and the rotation of gear 6 drives gear 7 to rotate.

[0041] Among them, a second motor 10 is fixedly installed above the threaded block 9, and a connecting rod 11 is fixedly installed above the drive shaft of the second motor 10. One end of the connecting rod 11 extends into the interior of the heating chamber 3 and is fixedly installed with an auger 12.

[0042] The controller starts the motor 10, which drives the connecting rod 11 to rotate. When the connecting rod 11 rotates, it drives the auger 12 to rotate. The rotation of the auger 12 drives the heated plastic to be squeezed into the discharge pipe 17.

[0043] Among them, a baffle 26 is fixedly sleeved on the outer surface of the connecting rod 11, and the baffle 26 is located inside the heating chamber 3.

[0044] The design of the baffle 26 blocks the plastic from entering the heating chamber 3, preventing the plastic from entering the rear end of the auger 12. At the same time, when the auger 12 moves to the outside of the heating chamber 3, it can also move the baffle 26 to scrape the plastic inside the heating chamber 3.

[0045] The heating chamber 3 has a feed inlet 14 on its upper part, and the feed inlet 14 is internally connected to the screening chamber 18.

[0046] The material screened inside the screening chamber 18 can be added into the heating chamber 3 through the feed inlet 14.

[0047] The heating chamber 3 has a sealing threaded cover 15 threaded inside, with one end of the sealing threaded cover 15 extending to the outside of the heating chamber 3.

[0048] The design of the sealing threaded cap 15 facilitates the removal of the auger 12 from the interior of the heating chamber 3, thereby enabling the auger 12 to be cleaned.

[0049] The sealing threaded cover 15 has a handle 16 fixedly installed on one side, and a discharge pipe 17 is opened on one side of the sealing threaded cover 15. The discharge pipe 17 is connected to the interior of the heating chamber 3.

[0050] The handle 16 is designed to facilitate rotating the sealing threaded cover 15, thereby improving the ease of operation of the device.

[0051] The heating chamber 3 is fitted with a heating plate 13, which is located outside the feed inlet 14.

[0052] By activating the heating plate 13 via the controller, the plastic inside the heating chamber 3 will be heated and melted.

[0053] Working principle and usage process of this utility model:

[0054] When the operator uses the device, they first start the motor 20 via the controller. Once the motor 20 starts, it drives the rotating plate 21 to rotate. When the rotating plate 21 rotates, it drives the protrusion 22 to make a circular motion. When the protrusion 22 makes a circular motion, the rotation of the moving frame 23 is restricted by the screen 25. Therefore, as the protrusion 22 rotates, it drives the moving frame 23 to make a reciprocating linear motion. When the moving frame 23 makes a reciprocating linear motion, it drives the connecting block 24 to make a reciprocating linear motion, thereby driving the screen 25 to make a reciprocating linear motion, thus screening the impurities above the screen 25.

[0055] When the operator uses the device, they first hold handle 16 and rotate the sealing threaded cover 15 to remove it from the heating chamber 3. Then, they start motor 5 via the controller. When motor 5 starts, it drives gear 6 to rotate. As gear 6 rotates, it meshes with gear 7, causing gear 7 to rotate. When gear 7 rotates, it drives threaded rod 8 to rotate. As threaded rod 8 rotates, it moves threaded block 9 because of the threaded connection between threaded block 9 and threaded rod 8. When threaded block 9 moves, it drives motor 10 to move, thus pushing auger 12 forward. When auger 12 is completely removed from the heating chamber 3, motor 5 can be turned off.
