In this way, a high fault tolerance can be achieved.

As a feasible matter, similarly, in order to facilitate the detachable butt joint of the first mold temperature controller 1, the cross-linking extruder head 2 and the pipeline control device 4, the first inlet 11 is connected with the first interface 41 through the pluggable joint 5; the first outlet 12 is connected with the second interface 42 through a pluggable connector 5; the second inlet 21 is connected with the fourth interface 44 through a pluggable joint 5; the second outlet 22 is connected to the third interface 43 via a pluggable connector 5.
The pluggable connector 5 in this application may be a quick-connect-disconnect connector, preferably a temperature-resistant connector, which may be divided into a matched male and female connector. For example, the quick-connect/disconnect coupling may be a hydraulic quick-connect coupling, and specifically may be a brass hydraulic quick-connect coupling of the KZD standard, including a SF female coupling and a PF male coupling, which can withstand temperatures between-30 degrees and 180 degrees, whereas for a mold temperature machine, the normal service temperature is between 50 degrees and 120 degrees, and the above-mentioned quick-connect/disconnect coupling can completely meet the requirements. Therefore, the corresponding pluggable joints 5 can be connected and separated instantly, and therefore the connection and separation of the first mold temperature controller 1, the second mold temperature controller 3, the cross-linking plastic extruder head 2 and the pipeline control device 4 can be conveniently and rapidly achieved. This eliminates the need for a separate standby die temperature machine for each crosslinking extruder head 2. The pipelines between the first mold temperature controller 1, the second mold temperature controller 3, the cross-linking extruder head 2 and the pipeline control device 4 in the application can adopt flexible pipes, in particular the pipeline connecting the pipeline control device 4 and the second mold temperature controller 3, so that the replacement of the second mold temperature controller 3 can be facilitated. Specifically, the hose can adopt a metal hose, so that the purpose of high temperature resistance can be achieved, the high temperature resistance can reach about 400 ℃, and the use requirement is completely met.
As shown in fig. 5, the first mold temperature controller 1 has a self-heating function, when the first branch 411 is connected and the first pipeline 47 and the second pipeline 48 are disconnected, the first mold temperature controller 1 can circularly heat the heat-conducting fluid medium in the interior and the related pipelines to a set precise temperature, such as a first preset temperature, which is also the temperature required by the head 2 of the crosslinking extruder for the heat-conducting fluid medium, so that the first mold temperature controller 1 can directly control the temperature of the head 2 of the crosslinking extruder at a later stage, and the temperature fluctuation of the head 2 of the crosslinking extruder during switching can not be caused, which affects production.
As shown in fig. 1, the second mold temperature controller 3 has a self-heating function, when the second branch 412 is connected and the third pipe 49 and the fourth pipe 410 are disconnected, the second mold temperature controller 3 can circularly heat the heat-conducting fluid medium in the interior and the related pipes to a set precise temperature, such as a first preset temperature, which is also the temperature required by the head 2 of the crosslinking extruder for the heat-conducting fluid medium, so that the second mold temperature controller 3 can directly control the temperature of the head 2 of the crosslinking extruder at a later stage, and the temperature fluctuation of the head 2 of the crosslinking extruder during switching can not be caused, which affects production.
The first mold temperature controller 1 in the mold temperature controller system of the cable crosslinking production line has no fault, and during normal use, the mold temperature controller system of the cable crosslinking production line has a first operation state, as shown in fig. 3, in the first operation state: the first line 47 is in a connected state, the second line 48 is in a connected state, the first branch 411 is in a disconnected state, the third line 49 is in a disconnected state, the fourth line 410 is in a disconnected state, and the second branch 412 is in a connected state; the first mold temperature controller 1 starts a normal operation function, and the second mold temperature controller 3 starts a self-heating function. That is, at this time, the fifth opening/closing valve 417, the third opening/closing valve 415, and the fourth opening/closing valve 416 are in a closed state, the first opening/closing valve 413, the second opening/closing valve 414, and the sixth opening/closing valve 418 are opened, the first mold temperature controller 1 directly controls the temperature of the crosslinking extruder head 2, and the second mold temperature controller 3 performs self-heating for standby.
When first mould temperature machine 1 broke down, second mould temperature machine 3 can dock with crosslinking extruding machine aircraft nose 2, avoided leading to the temperature fluctuation of crosslinking extruding machine aircraft nose 2. When the second mold temperature machine 3 is docked with the crosslinking extruder head 2, the cable crosslinking production line mold temperature machine system has a second operating state, as shown in fig. 4, in which: the first line 47 is in a disconnected state, the second line 48 is in a disconnected state, the third line 49 is in a connected state, the fourth line 410 is in a connected state, and the second branch 412 is in a disconnected state. The second mold temperature controller 3 starts a normal operation function. That is, at this time, the third opening/closing valve 415 and the fourth opening/closing valve 416 are opened, the first opening/closing valve 413, the second opening/closing valve 414 and the sixth opening/closing valve 418 are closed, and the second mold temperature controller 3 directly controls the temperature of the crosslinking extruder head 2.
The first mold temperature controller 1 can be detached from the pipe controller 4 through the detachable joint 5 for repair. After the trouble of the first mold temperature controller 1 is repaired, the first mold temperature controller 1 is mounted to the first port 41 and the second port 42 of the line control device 4. Thereafter, as shown in fig. 5, the fifth opening/closing valve 417 is opened, the line control device 4 is in the third operating state, and in the third operating state, the first line 47 is in the disconnected state, the second line 48 is in the disconnected state, the third line 49 is in the connected state, the fourth line 410 is in the connected state, the second branch 412 is in the disconnected state, the first branch 411 is in the connected state, and the self-heating function of the first mold temperature controller 1 is opened. In this way, the heat transfer medium inside the first mold temperature controller 1 and in the related piping can be heated cyclically to the set precise temperature, thereby preparing to switch the second mold temperature controller 3 to the first mold temperature controller 1. And the mould temperature controller system of the cable crosslinking production line is switched from the third operation state to the first operation state, so that the second mould temperature controller 3 is switched to the first mould temperature controller 1. Through the process, the mould temperature machine system of the cable cross-linking production line is switched to a first running state, the first mould temperature machine 1 directly controls the temperature of the cross-linking plastic extruding machine head 2, and the second mould temperature machine 3 carries out self-heating for standby.
Further, fig. 2 is a schematic structural diagram of a cable crosslinking line mold temperature controller system in a second embodiment according to an embodiment of the present invention, and as shown in fig. 2, the cable crosslinking line mold temperature controller system may include a plurality of crosslinking extruder heads 2, a plurality of first mold temperature controllers 1 corresponding to the crosslinking extruder heads 2, and a plurality of second mold temperature controllers 3. The number of the second mold temperature machines 3 can be less than or equal to the number of the first mold temperature machines 1.
The line control device 4 has a plurality of first line 47 switching units and a plurality of second line 48 switching units corresponding to the cross-linking extruder head 2. One of the first line switching units 100 includes: the first port 41, the second port 42, the third port 43, the fourth port 44, the first branch 411, the first line 47, and the second line 48. One of the second line switching units 200 includes: the fifth port 45, the sixth port 46, the third line 49, the fourth line 410, and the second branch 412. The third pipeline 49 of each second pipeline switching unit 200 is respectively communicated with the third ports 43 of the plurality of first pipeline switching units 100, and an independent third opening and closing valve 415 can be arranged between the third pipeline 49 and the third port 43 of each first pipeline switching unit 100, so that mutual interference of fluid among the plurality of third ports 43 can be prevented, and the plurality of independent third opening and closing valves 415 are schematically shown in fig. 2 and are not shown. The fourth pipeline 410 of each second pipeline switching unit 200 is respectively communicated with the fourth ports 44 of the first pipeline switching units 100. Similarly, there may be an independent fourth closing valve 416 between the fourth pipeline 410 and the fourth port 44 in each of the first pipeline switching units 100. The number of the second pipeline switching units 200 is less than or equal to the number of the first pipeline switching units 100.
In the above embodiment, a plurality of crosslinking extruder heads 2 and a plurality of first mold heaters 1 are connected to the line control device 4. A crosslinking extruder head 2 is used in conjunction with a first mold temperature machine 1. Meanwhile, a plurality of second mold temperature controllers 3 are connected to the pipeline control device 4. When any one of the first mold temperature controllers 1 fails, any one of the second mold temperature controllers 3 can be switched by the pipeline control device 4 to replace the failed first mold temperature controller 1. If one first mold temperature controller 1 in the system has a fault, the redundant second mold temperature controller 3 can be switched by the pipeline control device 4 to replace the second first mold temperature controller 1 with the fault. And after the first mold temperature controller 1 with the fault is repaired, switching back.
The advantage of the above embodiment is that the number of second mold heaters 3 can be reduced considerably with the same number of first mold heaters 1 and crosslinking extruder heads 2. For example, originally 10 cross-linking extruder heads 2 need to be configured with 10 main mold temperature machines, and then 10 standby mold temperature machines, since the pipe connections between them are fixed and cannot be adjusted, one cross-linking extruder head 2 corresponds to one main mold temperature machine and one standby mold temperature machine. After the mold temperature controller system of the cable crosslinking production line is adopted, N crosslinking extruder heads 2 are required to be provided with N first mold temperature controllers 1, but only a small number of second mold temperature controllers 3 are required to be provided, and the number of the second mold temperature controllers 3 can be less than N, and can be at least one. For the sake of safety, it is sufficient to avoid the simultaneous failure of a plurality of first mold temperature controllers 1 in one system, and generally, the number of second mold temperature controllers 3 is about N/2. After each of the first mold heaters 1 fails, any one of the second mold heaters 3 may be connected to the corresponding cross-linking extruder head 2 through the pipe control device 4, thereby replacing the failed first mold heater 1. The cost of the second mold temperature controller 3 can be greatly reduced through the mode. In addition, in the application, the first mold temperature controller 1 can be automatically switched to the second mold temperature controller 3 through the pipeline control device 4, the second mold temperature controller 3 can be switched to the first mold temperature controller 1 for one time, and multiple times of switching between the first mold temperature controller and the second mold temperature controller can also be realized. In addition, when the first die temperature machine 1 corresponding to the cross-linking extruder head 2 breaks down, the second die temperature machine 3 is switched to, and if the second die temperature machine 3 breaks down again before the first die temperature machine 1 is not repaired, other second die temperature machines 3 can be connected to the corresponding cross-linking extruder head 2 through the pipeline control device 4, and basically no adverse effect is caused on the cross-linking extruder head 2.
