Description

Technical Field

[0001] The present application relates to the field of cross-linking line production equipment, and in particular to a mold temperature controller switching system. Background Art

[0002] During the production process of the cross-linking line, the water mold temperature controller needs to output the constant temperature water required for the process through the internal circulation control system to heat the die head. Usually, a cross-linking line die head needs to be equipped with three mold temperature controllers for heating. If any mold temperature controller fails, the die head temperature control will be abnormal, affecting the cross-linking production products.

[0003] There are many ways to control the water mold temperature controller for the cross-linking die head. For example, when three main mold temperature controllers are used, they are connected to each other through a coil pipe. If any mold temperature controller fails, the faulty mold temperature controller is turned off, and the coil pipe is opened to heat the other mold temperature controllers. However, this method will result in insufficient heat provided by the mold temperature controller to the die head. Utility Model Content

[0004] In order to solve the problem of insufficient heat provided to the die head due to failure of some mold temperature controllers when multiple mold temperature controllers are working, an embodiment of the present application provides a mold temperature controller switching system with low cost and no impact on product production.

[0005] An embodiment of the present application provides a mold temperature controller switching system for heating a cross-linking line die head, the mold temperature controller switching system comprising a plurality of main mold temperature controllers, a standby mold temperature controller and a control component. The main mold temperature controller has a first state and a second state, the first state being configured such that the main mold temperature controller is connected to the die head, and the second state being configured such that the main mold temperature controller is blocked from the die head. The standby mold temperature controller has a third state and a fourth state, the third state being configured such that the standby mold temperature controller is blocked from the die head, and the fourth state being configured such that the standby mold temperature controller is connected to the die head. The control component is configured to control the plurality of main mold temperature controllers to switch to the first state or the second state, and the control component is further configured to control the standby mold temperature controller to switch to the third state or the fourth state.

[0006] Among them, when the main mold temperature controller is working normally, multiple main mold temperature controllers are configured to the first state, and the backup mold temperature controller is configured to the third state; when any one of the main mold temperature controllers fails, the control component controls the failed main mold temperature controller to switch to the second state, and controls the backup mold temperature controller to switch to the fourth state.

[0007] It is understandable that when any main mold temperature controller fails, the control system controls the main mold temperature controller to switch from the first state to the second state, and at the same time switches the standby mold temperature controller from the third state to the fourth state, so that the standby mold temperature controller can replace the failed main mold temperature controller and continue to work to meet the use of the die head without affecting product production. At the same time, multiple main mold temperature controllers share one standby mold temperature controller, which can reduce costs and meet demand.

[0008] In one embodiment, the first outlet of the main mold temperature controller is connected to the die head through a first pipeline, and a first valve group is provided on the first pipeline, and the first valve group can control the connection or blocking of the first pipeline.

[0009] In one embodiment, the second outlet of the standby mold temperature controller is connected to the die head via a second pipeline, and a second valve group is provided on the second pipeline, and the second valve group can control the connection or blocking of the second pipeline.

[0010] In one embodiment, the first pipelines connected to the plurality of main mold temperature controllers are all in communication with the second pipeline, and the connecting end of the second pipeline and the first pipeline is located at an end of the first valve group close to the die head.

[0011] In one embodiment, the second outlet of the standby mold temperature controller is connected to the first inlet of the standby mold temperature controller through a third pipeline, and a third valve group is provided on the third pipeline, and the third valve group can control the connection or blocking of the third pipeline.

[0012] In one embodiment, the third pipeline is communicated with the second pipeline, and a connecting end of the third pipeline and the second pipeline is located at an end of the third valve group away from the machine head.

[0013] In one embodiment, the main mold temperature controller further includes a second flow inlet, the second flow inlet is connected to the die head via a fourth pipeline, a fourth valve group is provided on the fourth pipeline, and the fourth valve group can control the connection or blocking of the fourth pipeline.

[0014] In one embodiment, the third pipeline is connected to the fourth pipeline through a fifth pipeline. A fifth valve group is provided on the fifth pipeline, and the fifth valve group can control the connection or blocking of the fourth pipeline.

[0015] In one embodiment, the mold temperature controller switching system further includes a water supply component, and the water supply component is connected to the third flow inlet of the main mold temperature controller and the fourth flow inlet of the standby mold temperature controller.

[0016] In one embodiment, the mold temperature controller switching system further includes a fault judgment unit, and the fault judgment unit is configured to judge whether the main mold temperature controller is faulty. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 to Figure 2 As shown, the embodiment of the present application provides a mold temperature controller switching system 100 for heating the cross-linking line head 200, and the mold temperature controller switching system 100 includes a plurality of main mold temperature controllers 1, a standby mold temperature controller 2, and a control component 11. The main mold temperature controller 1 has a first state and a second state, the first state is configured as the main mold temperature controller 1 is connected to the head 200, and the second state is configured as the main mold temperature controller 1 is blocked from the head 200. The standby mold temperature controller 2 has a third state and a fourth state, the third state is configured as the standby mold temperature controller 2 is blocked from the head 200, and the fourth state is configured as the standby mold temperature controller 2 is connected to the head 200. The control component 11 is configured to control the plurality of main mold temperature controllers 1 to switch to the first state or the second state, and the control component 11 is also configured to control the standby mold temperature controller 2 to switch to the third state or the fourth state.

[0027] When the main mold temperature controller 1 works normally, the multiple main mold temperature controllers 1 are configured to the first state, and the standby mold temperature controller 2 is configured to the third state. When any main mold temperature controller 1 fails, the control component 11 controls the failed main mold temperature controller 1 to switch to the second state, and controls the standby mold temperature controller 2 to switch to the fourth state.

[0028] In this embodiment, three main mold temperature controllers 1 can be provided, and the standby mold temperature controller 2 can start heating together with the main mold temperature controller 1 when in use, so that the standby mold temperature controller 2 can be put into use immediately when the main mold temperature controller 1 fails, without waiting for the standby mold temperature controller 2 to heat, and does not affect the use of the head 200. The object heated to the head 200 is usually a liquid, which can be transported to the head 200 for heating through the main mold temperature controller 1 and the standby mold temperature controller 2. Furthermore, the liquid can be water. The control component 11 can select a host computer, which can control the connection between the main mold temperature controller 1 and the head 200 and the connection between the standby mold temperature controller 2 and the head 200, and no excessive restrictions are made here.

[0029] It is understandable that when any main mold temperature controller 1 fails, the control system controls the main mold temperature controller 1 to switch from the first state to the second state, and at the same time switches the standby mold temperature controller 2 from the third state to the fourth state, so that the standby mold temperature controller 2 can replace the failed main mold temperature controller 1 and continue to work to meet the use of the die head 200 without affecting product production. At the same time, multiple main mold temperature controllers 1 share one standby mold temperature controller 2, which can reduce costs and meet demand.

[0030] In one embodiment, the mold temperature controller switching system 100 further includes a fault judgment unit (not shown in the figure), and the fault judgment unit is configured to judge whether the main mold temperature controller 1 is faulty.

[0031] In this embodiment, the control component 11 is a PLC industrial controller, and the fault judgment unit is a built-in module of the PLC industrial controller. When the main mold temperature machine 1 fails to output, the fault judgment unit can judge the fault and control the faulty main mold temperature machine 1 through the control component 11 to no longer be connected to the die head 200, so that the standby mold temperature machine 2 is cut in and connected to the die head 200. The fault judgment unit can judge whether the current main mold temperature machine 1 has a fault according to whether liquid flows out of the outlet end of each main mold temperature machine 1 or the temperature of the liquid flowing out.

[0032] It can be understood that the fault judgment unit can determine whether the main mold temperature controller 1 is faulty, and can enable the control component 11 to control the faulty main mold temperature controller 1 to no longer continue to heat the head 200, but to connect the spare mold temperature controller 2 to the head 200 for heating, so that the head 200 can be used normally.

[0033] In one embodiment, if Figure 3 As shown, the first outlet 101 of the main mold temperature controller 1 is connected to the die head 200 through the first pipeline 3. The first pipeline 3 is provided with a first valve group 301, and the first valve group 301 can control the connection or blocking of the first pipeline 3.

[0034] In this embodiment, the water heated by the main mold temperature controller 1 flows into the first pipeline 3 through the first outlet 101, and then flows into the die head 200 through the first pipeline 3, so as to achieve the purpose of heating the die head 200. Among them, the first valve group 301 includes a ball valve and a normally open solenoid valve, and the normally open solenoid valve allows the first pipeline 3 to be connected under normal circumstances, and the water in the main mold temperature controller 1 can flow into the die head 200. Each main mold temperature controller 1 has a first outlet 101 and is connected to the die head 200 through the first pipeline 3. In addition, each first pipeline 3 connected to the main mold temperature controller 1 is provided with a first valve group 301.

[0035] It can be understood that, by setting the first valve group 301, the water in the main mold temperature controller 1 can be prevented from flowing into the die head 200 when a fault occurs, thereby ensuring that the die head 200 is not affected by the water heated by the main mold temperature controller 1. At the same time, when the main mold temperature controller 1 is in normal use, the water heated by the main mold temperature controller 1 can also smoothly flow into the die head 200 to heat the die head 200.

[0036] In one embodiment, if Figure 4 As shown, the second outlet 201 of the standby mold temperature controller 2 is connected to the die head 200 through a second pipeline 4, and a second valve group 401 is provided on the second pipeline 4. The second valve group 401 can control the connection or blocking of the second pipeline 4.

[0037] In this embodiment, the water heated by the standby mold temperature controller 2 can flow into the second pipeline 4 through the second outlet 201, and then flow into the die head 200 through the second pipeline 4, so as to achieve the purpose of heating the die head 200. The second valve group 401 includes a ball valve and a normally closed solenoid valve. The normally closed solenoid valve blocks the second pipeline 4 under normal circumstances, and the water heated in the standby mold temperature controller 2 cannot pass through the second pipeline 4. Only when the main mold temperature controller 1 fails, the normally closed solenoid valve opens, and the water in the standby mold temperature controller 2 can flow into the die head 200 through the second pipeline 4.

[0038] It can be understood that the setting of the second valve group 401 makes it possible to control whether the standby mold temperature controller 2 is connected to the machine head 200. The standby mold temperature controller 2 is connected to the machine head 200 only when needed, and the heated water can smoothly enter the machine head 200 to heat the machine head 200.

[0039] In one embodiment, the first pipelines 3 connected to the multiple main mold temperature controllers 1 are all connected to the second pipeline 4 , and the connecting end of the second pipeline 4 and the first pipeline 3 is located at one end of the first valve group 301 close to the die head 200 .

[0040] In this embodiment, after the water of the standby mold temperature controller 2 flows into the second pipeline 4 through the second outlet 201, the second valve group 401 connects or blocks the second pipeline 4. When the second pipeline 4 is connected, the water output from the standby mold temperature controller 2 enters the first pipeline 3 without passing through the first valve group 301. When the second valve group 401 connects the second pipeline 4, the first valve group 301 blocks the end of the first pipeline 3 close to the main mold temperature controller 1. At this time, the water in the main mold temperature controller 1 cannot flow into the die head 200 through the first pipeline 3, while the water in the standby mold temperature controller 2 can flow into the unblocked part of the first pipeline 3 through the second pipeline 4 and continue to flow into the die head 200 to heat the die head 200.

[0041] It can be understood that after the second pipeline 4 is connected with the first pipeline 3, the water in the standby mold temperature controller 2 can enter the first pipeline 3 through the second pipeline 4 and then enter the machine head 200, so as to realize the connection between the standby mold temperature controller 2 and the machine head 200 while facilitating the standby mold temperature controller 2 to replace the faulty main mold temperature controller 1.

[0042] In one embodiment, if Figure 5 As shown, the second outlet 201 of the standby mold temperature controller 2 is connected to the first inlet 202 of the standby mold temperature controller 2 through the third pipeline 5. A third valve group 501 is provided on the third pipeline 5, and the third valve group 501 can control the connection or blocking of the third pipeline 5.

[0043] In this embodiment, the standby mold temperature controller 2 has a first inlet 202, and the second outlet 201 of the standby mold temperature controller 2 is connected to the first inlet 202 through the third pipeline 5, so that the water output from the standby mold temperature controller 2 can circulate in the third pipeline 5 when it is not necessary to enter the die head 200. The third valve group 501 includes a normally open solenoid valve. Under normal circumstances, the standby mold temperature controller 2 does not need to work, and the water heated by the standby mold temperature controller 2 circulates in the third pipeline 5.

[0044] It is understandable that the setting of the third pipeline 5 ensures that after the standby mold temperature controller 2 and the main mold temperature controller 1 are started simultaneously, the standby mold temperature controller 2 is in a state of being ready for use at any time without waiting for heating, thereby ensuring that the die head 200 is in good use.

[0045] In one embodiment, the third pipeline 5 is communicated with the second pipeline 4 , and the connecting end of the third pipeline 5 and the second pipeline 4 is located at an end of the third valve group 501 away from the handpiece 200 .

[0046] In this embodiment, the connection end of the third pipeline 5 and the second pipeline 4 is located at the end of the third valve group 501 away from the die head 200, so that the water output by the standby mold temperature controller 2 needs to pass through the third valve group 501 when entering the third pipeline 5. After the third pipeline 5 is connected with the second pipeline 4, when the standby mold temperature controller 2 needs to deliver water to the die head 200, the normally open solenoid valve in the third pipeline 5 is closed, and the normally closed solenoid valve in the second pipeline 4 is opened, and the water output by the standby mold temperature controller 2 no longer goes through the third pipeline 5 but goes through the second pipeline 4 to enter the die head 200. In this way, the switching of the standby mold temperature controller 2 is achieved.

[0047] It can be understood that the third pipeline 5 is connected to the second pipeline 4 so that when the standby mold temperature controller 2 is needed to deliver water to the machine head 200, the water circulating in the third pipeline 5 of the standby mold temperature controller 2 can immediately enter the second pipeline 4 and then enter the first pipeline 3 to be put into use quickly without waiting and without affecting the use of the machine head 200.

[0048] In one embodiment, the main mold temperature controller 1 further includes a second inlet 102 , which is connected to the die head 200 via a fourth pipeline 6 , and a fourth valve group 601 is provided on the fourth pipeline 6 , which can control whether the fourth pipeline 6 is connected or blocked.

[0049] In this embodiment, each main mold temperature controller 1 has a second inlet 102, and each main mold temperature controller 1 is connected to the die head 200 through the fourth pipeline 6. The water output from the die head 200 enters the main mold temperature controller 1 through the fourth pipeline 6 and then through the second inlet 102. The fourth valve group 601 includes a ball valve and a normally open solenoid valve. Under normal circumstances, the normally open solenoid valve is in a normally open state, and the water in the die head 200 can enter the main mold temperature controller 1. When the main mold temperature controller 1 fails, the normally open solenoid valve in the fourth valve group 601 is closed, and the water output from the die head 200 no longer enters the main mold temperature controller 1.

[0050] It is understandable that the main mold temperature controller 1 delivers heated water to the die head 200 through the first pipeline 3 to heat the die head 200, and the die head 200 also outputs unnecessary water through the fourth pipeline 6 to the main mold temperature controller 1. The fourth valve group 601 is set so that when the main mold temperature controller 1 fails, the water output by the die head 200 no longer enters the failed main mold temperature controller 1, ensuring that the die head 200 is in good use.

[0051] In one embodiment, the third pipeline 5 is connected to the fourth pipeline 6 via the fifth pipeline 7 , and the fifth pipeline 7 is provided with a fifth valve group 701 , which can control the fourth pipeline 6 to be connected or blocked.

[0052] In this embodiment, the fifth valve group 701 includes a ball valve and a normally closed solenoid valve, the connection end of the fifth pipeline 7 and the fourth pipeline 6 is located at the end of the fourth valve group 601 close to the handpiece 200, and the connection end of the fifth pipeline 7 and the third pipeline 5 is located at the end of the third valve group 501 close to the handpiece 200. Under normal circumstances, the normally closed solenoid valve in the fifth valve group 701 is closed, the fifth pipeline 7 is blocked, and water cannot flow through the fifth pipeline 7.

[0053] It is understandable that when the main mold temperature controller 1 fails, the second inlet 102 and the first outlet 101 are no longer in use, and the second outlet 201 and the first inlet 202 of the standby mold temperature controller 2 need to be put into use. Since the first inlet 202 and the second outlet 201 of the standby mold temperature controller 2 are normally connected through the third pipeline 5 and water circulates in the third pipeline 5, when the standby mold temperature controller 2 needs to be connected with the machine head 200, the fourth valve group 601 on the fourth pipeline 6 is closed, and the third valve group 501 on the third pipeline 5 is also closed, and the fifth valve group 701 on the fifth pipeline 7 connecting the third pipeline 5 and the fourth pipeline 6 is opened, and the water output from the machine head 200 enters the fifth pipeline 7 through the fourth pipeline 6, and then enters the first inlet 202 through the opened fifth valve group 701 to enter the standby mold temperature controller 2. In this way, the failed main mold temperature controller 1 is switched to the standby mold temperature controller 2 and the machine head 200 continues to be heated.

[0054] In one embodiment, if Figures 1 to 5 As shown, the mold temperature controller switching system 100 also includes a water supply component (not shown in the figure), which is connected to the third inlet 103 of the main mold temperature controller 1 and the fourth inlet 203 of the standby mold temperature controller 2.

[0055] In this embodiment, the water supply component provides cooling water, and the cooling water enters the third inlet 103 and the fourth inlet 203 through the cooling water inlet 8 to enter the main mold temperature controller 1 and the standby mold temperature controller 2. The mold temperature controller heats the cooling water and then delivers it to the machine head 200.

[0056] In other embodiments, the main mold temperature controller 1 further has a third outlet 104 to allow cooling water to flow out, and the standby mold temperature controller 2 further has a fourth outlet 204 to allow cooling water to flow out, and the cooling water flowing out of the third outlet 104 and the fourth outlet 204 both flow out through the cooling water outlet 9. The main mold temperature controller 1 may also be provided with a first wastewater outlet 105 to allow wastewater to flow out, and the standby mold temperature controller 2 may also be provided with a second wastewater outlet 205 to allow wastewater to flow out, and the wastewater flowing out of the first wastewater outlet 105 and the second wastewater outlet 205 both flow out through the wastewater outlet 10.

[0057] It can be understood that the inlet and outlet of cooling water ensures that the mold temperature controller works well. At the same time, a waste water outlet can be provided to allow waste water to flow out, so that each mold temperature controller can work better.

[0058] In the above, the specific implementation of the present application is described with reference to the accompanying drawings. However, those skilled in the art will appreciate that various changes and substitutions may be made to the specific implementation of the present application without departing from the spirit and scope of the present application. These changes and substitutions are all within the scope defined by the present application.
