Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing equipment production technology, and in particular to a cable shielding material extrusion equipment with a quick mold changing structure. Background Technology

[0002] In modern society, cables are a key infrastructure for power transmission and information transmission. Their quality and production efficiency play a vital role in the development of various industries. As an important component of cables, cable shielding materials can effectively reduce electromagnetic interference and improve the transmission performance and stability of cables. Therefore, their production and manufacturing have received widespread attention.

[0003] Currently, the production of cable shielding materials mainly relies on extrusion equipment. Traditional cable shielding material extrusion equipment has many problems in the mold changing process. In the cable production process, in order to meet the needs of different specifications and models of cables, it is often necessary to change the extrusion mold. However, the mold changing process of traditional extrusion equipment is cumbersome and time-consuming because its mold connection structure design is complex and requires a large number of bolts, nuts and other connectors for fixing. Disassembling and installing these connectors requires a lot of manpower and time, resulting in frequent downtime for mold changing during the production process, which seriously affects production efficiency.

[0004] At the same time, its extrusion structure does not have an ideal extrusion effect on the material, and cannot fully compact the material, resulting in insufficient density of the extruded cable shielding layer and reducing the shielding performance of the cable.

[0005] To address the above issues, we have introduced a cable shielding material extrusion device with a quick mold-changing structure. Utility Model Content

[0006] This utility model discloses a cable shielding material extrusion device with a quick mold changing structure, which aims to solve the technical problems in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An extrusion device for cable shielding material with a quick-change mold structure includes an extrusion box. A first flange is fixedly connected to the bottom of the extrusion box. An extrusion mold is disposed below the extrusion box. A second flange is fixedly connected above the extrusion mold. Both the first and second flanges are rectangular structures. Through slots are symmetrically opened on the four sides of the first flange. Fixing blocks are symmetrically fixedly connected to the four sides of the first flange. A sleeve is rotatably connected between two corresponding fixing blocks. Limiting rods are threaded to both ends of the sleeve. A limiting block that cooperates with the through slots is fixedly connected above the second flange. A trapezoidal groove is opened inside the limiting block. A trapezoidal block that cooperates with the trapezoidal groove is provided at the end of the limiting rod near the corresponding limiting block. A wrench slot is opened in the middle section of the sleeve.

[0009] In a preferred embodiment, a first rotating shaft is rotatably connected inside the extrusion box, and a second rotating shaft is rotatably connected inside the extrusion box and below the first rotating shaft. Cams are symmetrically fixedly connected to the outer sides of both the first and second rotating shafts. The extrusion box has four pillars fixedly connected at equal intervals in a rectangular structure. Extrusion plates are slidably connected between the outer sides of the four pillars. All cams are in contact with the surface of the extrusion plates.

[0010] In a preferred embodiment, two rotating rods are symmetrically rotatably connected inside the extrusion box and above the first rotating shaft. First sprockets are fixedly connected to the outer side of the rotating rods and the outer side of the first rotating shaft. A first chain for transmission is provided between the two first sprockets. A stirring paddle is fixedly connected at equal intervals to the outer side of the rotating rods.

[0011] In a preferred embodiment, the cable shielding material extrusion equipment with a quick mold-changing structure is characterized in that: one end of both the first rotating shaft and the second rotating shaft extends to the outside of the extrusion box and is fixedly connected to a second sprocket, and a second chain for transmission is provided between the two second sprockets.

[0012] In a preferred embodiment, the cable shielding material extrusion equipment with a quick mold-changing structure is characterized in that: a motor is fixedly connected to one side of the extrusion box, and the output end of the motor is connected to a first rotating shaft.

[0013] In a preferred embodiment, the cable shielding material extrusion equipment with a quick mold-changing structure is characterized in that: heating plates are symmetrically and equidistantly fixedly connected to the outer side of the extrusion box.

[0014] In a preferred embodiment, the cable shielding material extrusion equipment with a quick mold-changing structure is characterized in that: both the heating plate and the motor are electrically connected to external control equipment.

[0015] The cable shielding material extrusion equipment with a quick mold-changing structure provided by this utility model has the following advantages:

[0016] Firstly, when it is necessary to replace the extrusion mold, insert the wrench slot into the middle of the socket and rotate the socket. Since the socket is threadedly connected to the limit rod, rotating the socket will cause the limit rod to move away from the limit block until the trapezoidal block at the end of the limit rod disengages from the trapezoidal groove inside the limit block. At this point, the connection between the second flange and the first flange is released, and the old extrusion mold can be removed. Align the limit block of the new extrusion mold with the through groove of the first flange and insert it. Rotate the socket in the opposite direction to move the limit rod towards the limit block. The trapezoidal block at the end of the limit rod will then engage with the trapezoidal groove inside the limit block, completing the installation of the new mold and achieving rapid mold change.

[0017] Secondly, when the equipment is running, the motor drives the first and second rotating shafts to rotate, and the cam on them pushes the extrusion plate to slide on the support column, extruding the cable shielding material in the box, making it compact and flowing into the mold.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application.

[0026] This utility model discloses a cable shielding material extrusion device with a quick mold changing structure.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a cable shielding material extrusion device with a quick-change mold structure includes an extrusion box 1, a first flange 2 fixedly connected to the bottom of the extrusion box, an extrusion mold 3 arranged below the extrusion box 1, and a second flange 4 fixedly connected above the extrusion mold 3. Both the first flange 2 and the second flange 4 are rectangular structures. Through grooves 5 are symmetrically opened on the four sides of the first flange 2, and fixing blocks 6 are symmetrically fixedly connected on the four sides of the first flange 2. Sleeves 7 are rotatably connected between two corresponding fixing blocks 6. Limiting rods 8 are threadedly connected to both ends of the sleeves 7. Limiting blocks 9 that cooperate with the through grooves 5 are fixedly connected above the second flange 4. Trapezoidal grooves are opened inside the limiting blocks 9. Trapezoidal blocks that cooperate with the trapezoidal grooves are set at the ends of the limiting rods 8 near the corresponding limiting blocks 9. Wrench slots 10 are opened in the middle section of the sleeves 7.

[0028] In this embodiment: When it is necessary to replace the extrusion mold 3, insert the wrench slot into the wrench slot 10 in the middle section of the sleeve 7 and rotate the sleeve 7. Since the sleeve 7 is threadedly connected to the limiting rod 8, rotating the sleeve 7 will cause the limiting rod 8 to move away from the limiting block 9 until the trapezoidal block at the end of the limiting rod 8 disengages from the trapezoidal structure groove inside the limiting block 9. At this time, the connection between the second flange 4 and the first flange 2 is released, and the old extrusion mold 3 can be removed. Align the limiting block 9 of the new extrusion mold 3 with the through slot 5 of the first flange 2 and insert it. Rotate the sleeve 7 in the opposite direction to move the limiting rod 8 toward the limiting block 9. The trapezoidal block at the end of the limiting rod 8 is engaged in the trapezoidal structure groove inside the limiting block 9, completing the installation of the new mold and realizing quick mold change.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, a first rotating shaft 11 is rotatably connected inside the extrusion box 1, and a second rotating shaft 12 is rotatably connected inside the extrusion box 1 and below the first rotating shaft 11. Cams 13 are symmetrically fixedly connected to the outer sides of both the first rotating shaft 11 and the second rotating shaft 12. Four pillars 14 are fixedly connected at equal intervals inside the extrusion box 1 in a rectangular structure. Extrusion plates 15 are slidably connected between the outer sides of the four pillars 14. The cams 13 are all in contact with the surface of the extrusion plates 15.

[0030] In this embodiment: when the equipment is running, the motor drives the first rotating shaft 11 and the second rotating shaft 12 to rotate. The cam 13 on the shaft pushes the extrusion plate 15 to slide on the support column 14, extruding the cable shielding material in the extrusion box 1, making it compact and flowing towards the mold.

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, two rotating rods 16 are symmetrically rotatably connected inside the extrusion box 1 and above the first rotating shaft 11. A first sprocket 17 is fixedly connected to the outer side of the rotating rod 16 and the outer side of the first rotating shaft 11. A first chain 18 for transmission is provided between the two first sprockets 17. An agitator 19 is fixedly connected at equal intervals to the outer side of the rotating rod 16.

[0032] In this embodiment: the first rotating shaft 11 rotates, which drives the rotating rod 16 to rotate through the first sprocket 17 and the first chain 18. The stirring paddle 19 stirs the cable shielding material in the box, so that the material is mixed evenly.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, one end of the first rotating shaft 11 and the second rotating shaft 12 both extend to the outside of the extrusion box 1 and are fixedly connected to a second sprocket 20, and a second chain 21 for transmission is provided between the two second sprockets 20.

[0034] In this embodiment: when the first rotating shaft 11 rotates, it drives the outer second sprocket 20, which in turn drives the second sprocket 20 of the second rotating shaft 12 to rotate via the second chain 21, thereby driving the second rotating shaft 12 to rotate, ensuring that the two shafts are synchronized.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, a motor 22 is fixedly connected to one side of the extrusion box 1, and the output end of the motor 22 is connected to the first rotating shaft 11.

[0036] In this embodiment, the output of motor 22 drives the first rotating shaft 11 to rotate, providing power for the operation of various components of the equipment.

[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, heating plates 23 are symmetrically and equidistantly fixedly connected to the outer side of the extrusion box 1.

[0038] In this embodiment, the heating plate 23 operates to heat the material in the extrusion box 1, bringing the material to a suitable temperature and ensuring extrusion quality.

[0039] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, both the heating plate 23 and the motor 22 are electrically connected to an external control device.

[0040] In this embodiment, the operator can use an external control device to start the motor 22 to make the equipment run, and can also adjust the temperature of the heating plate 23. When production ends, both can be turned off at the same time, which is convenient for control.

[0041] Working principle: When in use, firstly, the motor 22 starts and drives the first rotating shaft 11 to rotate. The first rotating shaft 11 drives the rotating rod 16 to rotate through the first chain 18 and the first sprocket 17. The stirring paddle 19 on the rotating rod 16 stirs and mixes the material in the extrusion box 1.

[0042] The first rotating shaft 12 is driven to rotate synchronously by the second chain 21 and the second sprocket 20. The cams 13 on the first rotating shaft 11 and the second rotating shaft 12 push the extrusion plate 15 to slide up and down along the support column 14 to extrude the material.

[0043] Heating plate 23 heats the material in extrusion box 1 to bring it to a molten state;

[0044] The molten material is extruded and shaped through the extrusion die 3 between the first flange 2 and the second flange 4;

[0045] When it is necessary to replace the extrusion die, use the wrench slot 10 to rotate the sleeve 7 so that the limit rod 8 is disengaged from the trapezoidal groove in the limit block 9, the fixation between the first flange 2 and the second flange 4 is released, and the extrusion die is quickly removed and replaced.

[0046] After the replacement is completed, rotate the sleeve 7 in the opposite direction so that the limiting rod 8 is reinserted into the trapezoidal groove of the limiting block 9, thereby achieving quick fixation of the first flange 2 and the second flange 4.

[0047] The entire equipment achieves material mixing, extrusion and squeezing through the coordinated work of motor 22, chain, sprocket and cam 13. At the same time, the quick mold changing structure improves production efficiency and meets the production needs of cable shielding materials of different specifications.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
