[0015] Example

[0016] In order to solve the above technical problems, this embodiment provides an extruder temperature detection device, such as Figure 1 As shown, the present invention comprises a preheating assembly 20 and an extruder head 30 which are sequentially arranged along the wire conveying direction, an inlet flange 33 is arranged at one end of the extruder head 30 which faces the preheating assembly 20, a first temperature detector 31 is connected to the inlet flange 33, a second temperature detector 32 is connected inside the extruder head 30, and a control system which is electrically connected to the preheating assembly 20 and the extruder head 30 is connected in communication with the first temperature detector 31 and the second temperature detector 32. The preheating assembly 20 is arranged before the wire enters the extruder head 30 for processing, and then the inlet flange 33 and the inner mold core rod 32 are connected to the inlet flange 33. The first temperature detector 31 and the second temperature detector 32 are respectively provided, so that when the wire is processed, the first temperature detector 31 and the second temperature detector 32 feed back the real-time heating temperature to the control system, and then the control system adjusts the heating temperature of the preheating component 20 and the inner mold core rod 34, so that when the wire is processed by the extruder head 30, the surface of the wire is heated evenly, and the temperature of the wire after preheating and when entering the head matches the temperature set in the head, so that the conductor surface obtains a better insulation material coating effect during the extrusion process, and the signal transmission quality of the finished cable is improved.

[0017] Specifically, the preheating component 20 includes a preheating pipe 21 and a protective shell 25 wrapped around the preheating pipe 21. A heating coil 23 is wound around the preheating pipe 21, and the heating coil 23 is electrically connected to the power output end of the control system. By winding the heating coil 23 around the preheating pipe 21 and then electrically connecting the output end of the control system to the heating coil 23, the heating coil 23 can adjust the uniform heating temperature required for the wire through the control system, and then by setting a protective shell 25 on the outside of the heating coil 23, the preheating pipe 21 is prevented from being affected by external environmental factors, so that the wire to be extruded can be preheated through feedback from the control system to ensure that the wire is heated evenly during the processing process.

[0018] In the above scheme, the extruder head 30 also includes an inner mold core rod 34, and temperature sensing probes are respectively inserted in the feed flange 33 and the inner mold core rod 34, and the first temperature detector 31 and the second temperature detector 32 are respectively connected to the temperature sensing probes. By inserting temperature sensing probes in the feed flange 33 and the inner mold core rod 34, and then providing the first temperature detector 31 and the second temperature detector 32 respectively connected to the temperature sensing probes, the control system can adjust the processing temperature in the feed flange 33 and the inner mold core rod 34 according to the real-time temperature feedback from the temperature sensing probe, thereby ensuring that the temperature of the wire after preheating and when entering the head matches the temperature set in the head, realizing real-time monitoring of the temperature in the feed flange 33 and the inner mold core rod 34, so as to cooperate with the control system to adjust the heating power.

[0019] Furthermore, the preheating component 20 also includes a plurality of high-temperature probes 24 inserted into the preheating pipe 21. The high-temperature probes 24 are evenly arranged along the axial direction of the preheating pipe 21. By inserting the high-temperature probes 24 on the surface of the preheating pipe 21, workers can monitor the temperature in the preheating pipe 21 in real time, thereby ensuring the normal operation of the preheating pipe 21 for wire preheating. The temperature in the preheating pipe 21 can be monitored in real time to ensure the normal operation of the wire preheating.

[0020] In order to improve the heating efficiency of the preheating pipe, as a preferred embodiment, the outer layer of the protective shell 25 is wrapped with an insulating layer 22. By coating the outer layer of the preheating component 20 with the insulating layer 22, the temperature loss in the preheating pipe 21 is effectively prevented, and the staff is prevented from accidentally touching the preheating component 20 and getting burned, thereby preventing the temperature inside the preheating component from diffusing, saving power consumption and ensuring uniform preheating of the wire.

[0021] Specifically, the preheating assembly 20 is detachably mounted on the extruder through the mounting plate 26 so that the preheating assembly 20 and the extruder head 30 are at the same horizontal plane. The preheating assembly 20 is detachably mounted on the extruder by using the mounting plate 26, and then the installation position of the preheating assembly 20 can be disassembled and adjusted by the fasteners before the wire processing to ensure that the preheating assembly 20 and the extruder head 30 are at the same horizontal plane during the working process, thereby realizing the adjustable installation of the preheating assembly 20 and ensuring that the preheating assembly 20 and the extruder head 30 are at the same horizontal plane during the processing.

[0022] In summary, in one or more embodiments of the present application, the present application comprises a preheating assembly and an extruder head sequentially arranged along the conveying direction of the wire, a feed flange is arranged at one end of the extruder head facing the preheating assembly, a first temperature detector is connected to the feed flange, a second temperature detector is connected inside the extruder head, and a control system electrically connected to the preheating assembly and the extruder head is further included, the control system is communicatively connected to the first temperature detector and the second temperature detector, and the preheating assembly is arranged before the wire enters the extruder head for processing, and the first temperature detector and the second temperature detector are respectively arranged on the feed flange and the inner mold core rod, so that the wire is fed back to the control system through the first temperature detector and the second temperature detector during processing, and then the heating temperature of the preheating assembly and the inner mold core rod is adjusted by the control system, so that when the wire is processed by the extruder head, the surface of the wire is heated evenly, the coating effect of the conductor on the surface of the wire is improved, and the temperature of the wire after preheating and when entering the head matches the temperature set in the head, so that the surface of the conductor obtains a better insulation material coating effect during the extrusion process, and the signal transmission quality of the finished cable is improved.
