Description

Technical Field

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

[0002] Cable processing refers to the entire process of processing raw materials such as metal conductors, insulation materials, shielding materials, and sheathing materials through a series of specific processes to ultimately produce cable products with the function of transmitting electrical energy or signals.

[0003] Plastic extruders are frequently used in cable processing. While existing plastic extruders can melt and extrude plastic raw materials, they lack the ability to mix multiple plastic materials evenly during the feeding stage. This results in uneven mixing of the plastic materials within the barrel, leading to variations in the material composition of different areas of the extruded cable insulation layer. Consequently, the protective performance of the cable insulation layer is affected, necessitating improvements. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a plastic extruder for cable processing, which solves the technical problem of uneven mixing of various plastic raw materials in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a plastic extruder for cable processing, comprising a mounting box, a support frame fixedly connected to the top of the mounting box, a barrel fixedly connected to the top of the support frame, a connecting pipe fixedly connected to the top of the barrel, a valve fixedly installed on the top of the connecting pipe, a feed box fixedly connected to the top of the valve, a stirring motor movably mounted at the center of the top of the feed box, a stirring shaft fixedly sleeved at the other end of the output shaft of the stirring motor, the bottom of the stirring shaft penetrating through the feed box and extending into the interior of the feed box and fixedly sleeved with stirring blades, a drive motor located behind the stirring motor fixedly connected to the top of the feed box, a rotating shaft fixedly sleeved at the other end of the output shaft of the drive motor, a rotating rod fixedly sleeved on the outer surface of the rotating shaft, a round shaft fixedly sleeved inside the other end of the rotating rod, a rectangular plate movably connected to the outer surface of the round shaft, and the bottom of the rectangular plate fixedly connected to the top of the stirring motor.

[0006] As a preferred embodiment of this utility model, a limiting rod is fixedly connected to the top of the feed box, and the outer surface of the limiting rod is movably sleeved with the inner surface of the rectangular plate.

[0007] As a preferred embodiment of this utility model, the number of limiting rods is two, the two limiting rods are the same size, and the two limiting rods are symmetrical about the center of the rectangular plate.

[0008] As a preferred embodiment of this utility model, the top of the feeding box is fixedly connected to a feeding port located directly in front of the stirring motor, and a cover plate is hinged to the top of the feeding port.

[0009] As a preferred embodiment of this utility model, a drive motor is fixedly connected to the right side of the barrel, and a drive shaft is fixedly sleeved at the other end of the output shaft of the drive motor. The left side of the drive shaft passes through the barrel and extends to the inner wall of the barrel, and a spiral blade is fixedly connected thereto.

[0010] As a preferred embodiment of this utility model, a heating plate is fixedly installed inside the barrel, and an extrusion head is fixedly connected to the left side of the barrel.

[0011] As a preferred embodiment of this utility model, a lifting motor is fixedly connected to the top of the inner cavity of the mounting box, a rotating shaft is fixedly sleeved at the other end of the output shaft of the lifting motor, and a rotating rod is fixedly sleeved on the outer surface of the rotating shaft.

[0012] As a preferred embodiment of this utility model, a cylindrical block is movably sleeved on the inner surface of the rotating rod, and a lifting plate is fixedly connected to the outer side of the cylindrical block.

[0013] As a preferred embodiment of this utility model, there are two lifting plates, and the outer surfaces of both lifting plates are movably connected to the inner surface of the mounting box.

[0015] The beneficial effects of this utility model are as follows: 1. In this utility model, by setting up a stirring blade, a drive motor, a rotating rod, a round shaft, and a rectangular plate, when the drive motor is running, the rotating shaft will cause the rotating rod to rotate, which in turn causes the round shaft to rotate and squeeze the rectangular plate and move it upward, thereby driving the stirring motor to move upward as a whole. At the same time, when the stirring motor is running, the stirring shaft will cause the stirring blade to rotate. With the rotation and up-and-down movement of the stirring blade, the plastic raw materials in the feed box are mixed more evenly, further ensuring the protective performance of the cable insulation layer.

[0016] 2. In this utility model, by setting up a lifting motor, a rotating shaft, a rotating rod, a cylindrical block, and lifting plates, when the lifting motor is running, the rotating shaft will drive the rotating rod to rotate. As the rotating rod rotates, it will squeeze and drive the cylindrical block to move upward, thereby driving the two lifting plates to move upward to block the area above the mounting box, thus preventing personnel from accidentally touching the barrel and causing burns, and improving the protective performance of the device.

[0025] like Figures 1-6The image shows a plastic extruder for cable processing according to an embodiment of the present disclosure, including a mounting box 1. A support frame 2 is fixedly connected to the top of the mounting box 1. A barrel 3 is fixedly connected to the top of the support frame 2. A connecting pipe 4 is fixedly connected to the top of the barrel 3. A valve 5 is fixedly installed on the top of the connecting pipe 4. A feed box 6 is fixedly connected to the top of the valve 5. A stirring motor 7 is movably installed in the middle of the top of the feed box 6. A stirring shaft 8 is fixedly sleeved at the other end of the output shaft of the stirring motor 7. The bottom of the stirring shaft 8 passes through the feed box 6 and extends into the interior of the feed box 6 and is fixedly sleeved with stirring blades 9. A drive motor 10 located behind the stirring motor 7 is fixedly connected to the top of the feed box 6. A rotating shaft 11 is fixedly sleeved at the other end of the output shaft of the drive motor 10. A rotating rod 12 is fixedly sleeved on the outer surface of the rotating shaft 11. A round shaft 13 is fixedly sleeved inside the other end of the rotating rod 12. A rectangular plate 14 is movably connected to the outer surface of the round shaft 13. The bottom of the rectangular plate 14 is fixedly connected to the top of the stirring motor 7.

[0026] The diameter of the round shaft 13 is the same as the height of the inner cavity of the rectangular plate 14. With this design, when the round shaft 13 rotates, it will squeeze the rectangular plate 14. As the position of the round shaft 13 inside the rectangular plate 14 changes with the rotation, it will drive the rectangular plate 14 and the stirring motor 7 to move upward as a whole.

[0027] In some examples, the top of the feed box 6 is fixedly connected to a limiting rod 15, and the outer surface of the limiting rod 15 is movably sleeved with the inner surface of the rectangular plate 14.

[0028] The design of the limit rod 15 serves to limit the rectangular plate 14, ensuring the stability of the lifting and lowering movement of the rectangular plate 14.

[0029] In some examples, there are two limit rods 15, both of the same size, and the two limit rods 15 are symmetrical about the center of the rectangular plate 14.

[0030] The design of the two limit rods 15 provides better control over the rectangular plate 14, making its lifting and lowering more stable.

[0031] In some examples, the top of the feed box 6 is fixedly connected to the feed port 16 located directly in front of the stirring motor 7, and the top of the feed port 16 is hinged to a cover plate 17.

[0032] Open the cover 17 to facilitate the addition of plastic raw materials into the feed box 6 through the feed port 16.

[0033] In some examples, a drive motor 18 is fixedly connected to the right side of the barrel 3, and a drive shaft 19 is fixedly sleeved at the other end of the output shaft of the drive motor 18. The left side of the drive shaft 19 passes through the barrel 3 and extends to the inner wall of the barrel 3 and is fixedly connected to a helical blade 20.

[0034] The spiral blade 20 adopts a spiral design and serves to transport plastic raw materials.

[0035] In some examples, a heating plate 22 is fixedly installed inside the barrel 3, and an extrusion head 21 is fixedly connected to the left side of the barrel 3.

[0036] The heating plate 22 is used to heat-melt and plasticize the plastic raw material, and the extrusion head 21 is designed to extrude the fused plastic raw material into a mold.

[0037] In some examples, a lifting motor 23 is fixedly connected to the top of the inner cavity of the mounting box 1, and a rotating shaft 24 is fixedly sleeved at the other end of the output shaft of the lifting motor 23. A rotating rod 25 is fixedly sleeved on the outer surface of the rotating shaft 24.

[0038] The lifting motor 23 has a self-locking function, which can prevent the rotating shaft 24 and the rotating rod 25 from reversing, thereby ensuring the stability of the rotating rod 25 after rotation.

[0039] In some examples, a cylindrical block 26 is movably sleeved on the inner surface of the rotating rod 25, and a lifting plate 27 is fixedly connected to the outer side of the cylindrical block 26.

[0040] The lifting plate 27 moves upward to form a barrier in the area above the mounting box 1, thereby preventing personnel from accidentally touching the barrel 3 and getting burned.

[0041] In some examples, there are two lifting plates 27, and the outer surfaces of both lifting plates 27 are movably connected to the inner surface of the mounting box 1.

[0042] The outer surfaces of both lifting plates 27 are smooth, which makes the sliding of the two lifting plates 27 inside the mounting box 1 smoother.

[0043] In some examples, a limiting plate 28 is fixedly connected to the outer surface of the top of the lifting plate 27, and the outer surface of the limiting plate 28 is movably connected to the inner surface of the top of the mounting box 1.

[0044] The design of the limit plate 28 serves to limit the lifting plate 27, ensuring the stability of the lifting movement of the lifting plate 27.

[0045] Working principle and usage process of this utility model: When processing cable insulation materials, first open the cover plate 17 and pour various plastic raw materials into the feed box 6 through the feed port 16. Then start the stirring motor 7, which will cause the stirring shaft 8 to drive the stirring blades 9 to rotate and mix the plastic raw materials. At the same time, start the drive motor 10, which will cause the rotating shaft 11 to drive the rotating rod 12 to rotate, which will cause the round shaft 13 to rotate and squeeze the rectangular plate 14 and drive it to move upward, thereby driving the stirring motor 7 to move upward as a whole. With the rotation and up and down movement of the stirring blades 9, the plastic raw materials in the feed box 6 are mixed more evenly, which further ensures the protective performance of the cable insulation layer. After the plastic raw materials are mixed, open the valve 5, which will allow the plastic raw materials in the feed box 6 to fall into the barrel 3 through the connecting pipe 4. At this time, start the drive motor 18, which will cause the drive shaft 19 to drive the spiral blades 20 to rotate and transport the plastic raw materials to the hot melt zone. After hot melt plasticization, the plastic materials are extruded and formed at the extrusion head 21 under pressure.

[0046] When the extruder is working, starting the lifting motor 23 will cause the rotating shaft 24 to drive the rotating rod 25 to rotate. As the rotating rod 25 rotates, it will squeeze and drive the cylindrical block 26 to move upward, which in turn will drive the two lifting plates 27 to move upward to block the area above the mounting box 1, thereby preventing personnel from accidentally touching the barrel 3 and causing burns, thus improving the protective performance of the device.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
