Abstract
Description
Technical Field
[0001] This utility model relates to the field of extruder technology, specifically to an electric wire and cable extruder. Background Technology
[0002] Wires and cables are wire products used to transmit electrical energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated conductors, and their respective possible covering layers, overall protective layer, and outer sheath. Cables may also have additional uninsulated conductors. Extrusion machines are required during the processing of wires and cables.
[0003] In the prior art, an extruder for wire and cable production, with patent authorization announcement number "CN 218660365 U", uses a preheating mechanism to add material to the inner shell through a feed hopper. After the material is added, the heating coil is energized to preheat the material in the inner shell. After the material is preheated for a period of time, the servo cylinder is activated, which drives the baffle to descend, and the material in the inner shell enters the fixed shell. The material in the fixed shell enters the extrusion cylinder through the feed pipe. By preheating the material in this way, the material can be quickly raised to the required temperature in the extrusion cylinder, effectively improving production efficiency. However, when the material is added to the preheating mechanism for heating, because the material is piled up in the preheating mechanism, it is impossible to ensure uniform heating of the material, which can easily lead to incomplete heating of the material. This not only makes it inconvenient for subsequent extrusion work, but also reduces processing efficiency to a certain extent. Utility Model Content

[0030] like Figures 1-5 As shown, it illustrates an embodiment of the present invention of an extruder for wires and cables, comprising: a base plate 1, a support frame 2 fixedly installed on the top left side of the base plate 1, a pretreatment chamber 3 vertically and fixedly installed on the support frame 2, a pretreatment mechanism installed on the pretreatment chamber 3, a feed hopper 11 fixedly installed on the top of the pretreatment chamber 3, a hopper cover 1101 rotatably installed on one side of the top of the feed hopper 11, a first handle 1102 fixedly installed on the top of the hopper cover 1101, an extrusion tube 5 fixedly installed on the top of the base plate 1, an extrusion head 6 installed on the outer wall of the right side of the extrusion tube 5, a connecting tube 4 fixedly installed at the bottom of the pretreatment chamber 3, the other end of the connecting tube 4 being connected to the extrusion tube 5, and an extrusion mechanism installed on the extrusion tube 5;
[0031] Support plate 24 is fixedly installed at the top and rear end of the base plate 1. The top end of the extrusion tube 5 is sealed with an installation tube 2401. The top end of the support plate 24 is fixedly connected to the bottom end of the installation tube 2401. An air filtering mechanism is installed on the installation tube 2401.
[0032] For example, such as Figure 2 As shown, the pretreatment mechanism includes a first motor 7, a first rotating shaft 8, a stirring rod 9, a first support 10, and a screw ribbon 12. The first motor 7 is fixedly installed at the middle position of the top of the pretreatment chamber 3. The first support 10 is fixedly installed at the bottom of the inside of the connecting pipe 4. The first rotating shaft 8 is fixedly installed at the output end of the first motor 7. The other end of the first rotating shaft 8 is rotatably connected to the first support 10. Several sets of stirring rods 9 are fixedly installed on the first rotating shaft 8. The screw ribbon 12 is also fixedly installed on the first rotating shaft 8. The outer wall of the screw ribbon 12 is in contact with the inner wall of the pretreatment chamber 3.
[0033] For example, such as Figure 2 As shown, the pretreatment mechanism also includes a first cavity 13, a first spiral heating tube 14, a first spiral auger 16 and a valve 17. The first cavity 13 is opened inside the side wall of the pretreatment chamber 3. The first spiral heating tube 14 is fixedly installed inside the first cavity 13. The first spiral auger 16 is fixedly installed on the first rotating shaft 8 inside the connecting pipe 4. The valve 17 is fixedly installed on the connecting pipe 4 at a position directly below the first support 10.
[0034] For example, such as Figure 2 As shown, the extrusion mechanism includes a second motor 18, a second rotating shaft 19, a second spiral auger 20, a second support 21, a third cavity 22, and a second spiral heating tube 23. The second motor 18 is fixedly installed on the outer left side of the extrusion tube 5, and the second support 21 is fixedly installed on the right side inside the extrusion tube 5. The second rotating shaft 19 is fixedly installed at the output end of the second motor 18, and the other end of the second rotating shaft 19 is rotatably connected to the second support 21. The second spiral auger 20 is fixedly installed on the second rotating shaft 19. The third cavity 22 is opened inside the outer wall of the extrusion tube 5, and the second spiral heating tube 23 is fixedly installed inside the third cavity 22. The first motor 7 is a servo motor, and the second motor 18 is a drive motor.
[0035] In some examples, when using this device, the operator first adds the material into the pretreatment chamber 3 through the feed hopper 11. Then, while the first motor 7 is rotating in reverse, the first spiral heating tube 14 is activated. This allows the material to be stirred and heated by the stirring rod 9, while the screw ribbon 12 continuously scrapes the inner wall of the pretreatment chamber 3, reducing the amount of material adhering to the inner wall and thus reducing material waste. Additionally, when the first motor 7 drives the first rotating shaft 8 to rotate, it also drives the first spiral auger 16 to rotate, allowing the material at the bottom of the pretreatment chamber 3 to be directed towards... The upward rotation further improves the uniformity of material heating. After the material is heated, the operator can start the first motor 7 to rotate forward and open the valve 17, allowing the material to enter the extrusion tube 5. At the same time, the operator can start the second motor 18 to drive the second auger 20 to transport the material. During the material transport process, the operator can also start the second spiral heating tube 23 to keep the transported material warm and prevent solidification during transport, thus making the device more practical.
[0036] like Figure 5 As shown, this is an example of a wire and cable extruder according to another embodiment of the present invention. The filtration mechanism includes a first mounting box 25, an activated carbon filter plate 26, a second handle 27, a second mounting box 28, a third bracket 29, and a suction fan 30. The first mounting box 25 is fixedly mounted on the mounting pipe 2401 and is connected to the mounting pipe 2401. The activated carbon filter plate 26 is slidably mounted on the top of the first mounting box 25, and the second handle 27 is fixedly mounted on the top of the activated carbon filter plate 26. The second handle 27 is located on the first mounting box 28 on the mounting pipe 2401. A second mounting box 28 is fixedly installed at the rear end of the box 25. The second mounting box 28 is connected to the mounting pipe 2401. A third bracket 29 is fixedly installed inside the second mounting box 28. A suction fan 30 is fixedly installed on the third bracket 29. Sealing gaskets are fixedly installed at the sliding connection between the activated carbon filter plate 26 and the outer surface of the first mounting box 25. A second cavity 15 is opened inside the outer wall of the pretreatment chamber 3 outside the first cavity 13. The second cavity 15 is filled with polyurethane foam. Rubber pads 31 are fixedly installed at the four corners of the bottom of the base plate 1.
[0037] In some examples, when the second motor 18 drives the second auger 20 to convey materials, the operator can activate the suction fan 30 to extract any harmful gases that may be generated after the materials are heated. At the same time, the activated carbon filter plate 26 can filter the harmful gases in the gas, reducing the amount of harmful gases emitted to the outside, thereby further improving the practicality of the device. In addition, the second cavity 15 and the polyurethane foam filling the second cavity 15 in this device can reduce heat loss and energy consumption. This not only saves energy but also keeps the temperature outside the pretreatment chamber 3 lower, making it safer to use.
