[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of the present application are described from the angles shown in the drawings and should not be construed as limiting the embodiments of the present application.

[0032] Referring to Figure 1 and Figure 2 as shown, Figure 1 is a schematic diagram of the cooling system of the pressing device provided by the embodiment of the present application, Figure 2 is a schematic structural diagram of the platen of the pressing device provided by the embodiment of the present application. This embodiment discloses a pressing device, which includes a frame, a plurality of platens 1, a driving assembly, a cooling system 2, and a detection assembly 3. The plurality of platens 1 are respectively movably arranged on the frame, and the plurality of platens 1 are respectively distributed along the height extension direction of the frame, so that a pressing layer is formed between adjacent two platens 1. The pressing layer is used to place the material 4 to be cooled. Each platen 1 is respectively provided with a fluid channel 11, and the fluid channel 11 is provided with a liquid inlet 110 and a liquid outlet 111. The driving assembly is connected to the platen 1 and is used to drive the platen 1 to move along the height extension direction of the frame, so as to press the material 4 to be cooled between adjacent two platens 1. The cooling system 2 is respectively connected to each liquid inlet 110 and each liquid outlet 111 and is used to cool each platen 1. The detection assembly 3 includes a plurality of temperature sensors 31 and a controller. Each temperature sensor 31 is respectively arranged on each platen 1 and is used to detect the temperature of each platen 1, thereby improving the refinement degree of the pressing device during the production process. The controller is respectively electrically connected to each temperature sensor 31 and is used to determine whether each platen 1 has an abnormality based on the detection results of each temperature sensor 31, so as to shield the platen 1 with an abnormality and not affect the normal operation of other platens 1, thereby improving the automation of the pressing device.

[0033] In this embodiment, each temperature sensor 31 is respectively located in the middle of each fluid channel 11. Since the cooling medium will gradually heat up when flowing through the fluid channel 11, resulting in a gradual decrease in the cooling effect, the temperature accuracy measured at the position near the liquid inlet 110 or the liquid outlet 111 is insufficient. By arranging the temperature sensor 31 in each fluid channel 11 and at the middle of the pressure plate 1 to detect the temperature of the inner wall of the fluid channel 11, the uniformity of temperature detection is ensured, and the accuracy of temperature detection is improved.

[0034] In this embodiment, the liquid inlet 110 and the liquid outlet 111 are respectively located on the same side of the pressure plate 1 for convenient connection. It can be understood that in other embodiments, the liquid inlet 110 and the liquid outlet 111 can also be respectively located on both sides of the pressure plate 1.

[0035] In this embodiment, the pressure plate 1 is made of a metal material with a coating, making the pressure plate 1 have certain corrosion resistance and wear resistance, and improving the service life of the pressure plate 1. Among them, the coating metal can include single metals or alloys such as chromium, zinc, nickel, copper, silver, etc., which are not limited herein.

[0036] Each temperature sensor 31 of this embodiment is respectively arranged on each pressure plate 1 to detect the temperature of each pressure plate 1. The controller is electrically connected to each temperature sensor 31 respectively, and is used to determine whether each pressure plate 1 has an abnormality based on the detection results of each temperature sensor 31, so as to quickly locate the position of the faulty component, specifically eliminate the fault source, improve the accuracy of fault detection of the pressing equipment, and can avoid placing the material 4 to be cooled on the faulty pressure plate 1 in the next production process, so that the pressing equipment does not need to stop for maintenance during the automated production process, greatly improving the durability of the pressing equipment and not producing a batch of defective materials, reducing costs and improving work efficiency.

[0037] Existing cooling devices mostly adopt the proportional-integral-derivative (English full name: Proportional-Integral-Derivative, abbreviated as: PID) control method to achieve the function of adjusting the temperature curve of the material by frequently opening and closing the solenoid valve 25. However, due to the large flow rate and pressure of the cooling water, if the solenoid valve 25 is frequently opened and closed, it is easy to damage the solenoid valve 25. Since the solenoid valve 25 is placed on the top of the cold press and at a relatively high height, it is very inconvenient and dangerous to replace.

[0038] Refer to Figure 1As shown, the cooling system 2 further includes an inlet pipeline 21, an outlet pipeline 22, and a proportional flow regulating valve 23. One end of the inlet pipeline 21 is connected to each liquid inlet 110, and the other end of the inlet pipeline 21 is used to connect to a liquid supply device. One end of the outlet pipeline 22 is connected to each liquid outlet 111, and the other end of the outlet pipeline 22 is used to connect to the liquid supply device. The proportional flow regulating valve 23 is arranged in the inlet pipeline 21 and connected to the controller. The controller is further used to control the opening degree of the proportional flow regulating valve 23 based on a preset cooling temperature, so that the flow rate of the cooling medium flowing through the fluid passage 11 of the pressure plate 1 can be controlled as needed to control the temperature of the material 4 to be cooled. Wherein, the preset cooling temperature is the cooling temperature required by the material 4 to be cooled.

[0039] In this embodiment, by adding a proportional flow regulating valve 23 to adjust the flow rate of the cooling medium flowing through the fluid passage 11, the temperature curve of the material is adjusted, greatly reducing the frequency of opening and closing the solenoid valve 25, thereby reducing the damage of the solenoid valve 25, improving the service life of the solenoid valve 25, reducing the frequency of maintenance and repair of the solenoid valve 25, and reducing the cost.

[0040] Refer to Figure 1 As shown, the cooling system 2 further includes an electric stop valve 24, a solenoid valve 25, a first pressure sensor 26, a second pressure sensor 27, and a third pressure sensor 28. The electric stop valve 24 is arranged in the inlet pipeline 21 and used to control the connection and disconnection of the inlet pipeline 21.

[0041] The first pressure sensor 26 and the second pressure sensor 27 are respectively arranged in the inlet pipeline 21, and the first pressure sensor 26 is located at the inlet end of the electric stop valve 24, and the second pressure sensor 27 is located at the outlet end of the electric stop valve 24. The controller is respectively connected to the first pressure sensor 26 and the second pressure sensor 27. The controller is further used to determine the pressure in the inlet pipeline 21 and whether the electric stop valve 24 has an abnormality based on the detection results of the first pressure sensor 26 and the second pressure sensor 27, so that problems can be discovered in time and the electric stop valve 24 can be replaced, improving the work efficiency. Under normal water flow conditions, the pressures of the first pressure sensor 26 and the second pressure sensor 27 are equal; if the pressure value detected by the first pressure sensor 26 is greater than the pressure value detected by the second pressure sensor 27, it indicates that the electric stop valve 24 is faulty or in an open state, resulting in the cooling medium being unable to flow out of the electric stop valve 24; if the first pressure sensor 26 detects no pressure, it indicates that the inlet pipeline 21 is not connected to the liquid supply device.

[0042] The solenoid valve 25 is arranged in the outlet pipeline 22 and used to control the connection and disconnection of the outlet pipeline 22, and the solenoid valve 25 is connected to the controller. When the material to be pressed has a heat preservation requirement, the controller controls the solenoid valve 25 to close.

[0043] The third pressure sensor 28 is disposed on the outflow pipeline 22 for detecting the pressure of the outflow pipeline 22, and the third pressure sensor 28 is connected to the controller. The controller is further configured to determine whether the solenoid valve 25 is abnormal based on the detection result of the third pressure sensor 28 and the detection result of the temperature sensor 31. If the pressure value detected by the third pressure sensor 28 continuously maintains at the pressure value set by the system and the temperature sensor 31 detects that the pressure plate 1 cools slowly, the solenoid valve 25 may be damaged or blocked, so that problems can be discovered in time and the solenoid valve 25 can be replaced, improving the work efficiency.

[0044] In this embodiment, by setting a plurality of pressure sensors and a plurality of temperature sensors 31, it is possible to accurately locate each faulty device in the system, thereby quickly eliminating the fault source and replacing it, improving the work efficiency. Moreover, by remotely controlling the electric stop valve 24, the solenoid valve 25 and other valves through the controller, the controllable electrical automation level is improved, the manpower is reduced, and the work efficiency is further improved.

[0045] Refer to Figure 1 As shown, the cooling system 2 further includes a safety overflow valve 29. The safety overflow valve 29 is connected in parallel with the solenoid valve 25, that is, both ends of the safety overflow valve 29 are respectively connected to both ends of the solenoid valve 25, and the safety overflow valve 29 is connected to the controller. The controller is further configured to control the opening and closing of the safety overflow valve 29 based on the detection result of the third pressure sensor 28. If the pressure of the cooling system 2 exceeds the pressure value set by the safety overflow valve 29, the controller controls the safety overflow valve 29 to open, so that the cooling medium flows back to the liquid supply device from the safety overflow valve 29, thereby reducing the situation that the pipeline pressure value is too large and causing the pipeline to burst, improving the safety and reliability of the cooling system 2, and ensuring the normal operation of the cooling system 2.

[0046] Refer to Figure 1 As shown, the cooling system 2 further includes a filter valve 20 and a heat exchanger (not shown in the figure). The filter valve 20 is disposed on the inflow pipeline 21 and at the inflow end of the first pressure sensor 26 for filtering the cooling medium flowing into the inflow pipeline 21 to filter out impurities in the cooling medium, thereby reducing the situation of blockage of the pipeline and the fluid passage 11, and ensuring the normal operation of the cooling system 2. The heat exchanger is disposed on the outflow pipeline 22 and at the outflow end of the solenoid valve 25 for reducing the temperature of the cooling medium flowing out of the outflow pipeline 22 when the return water temperature exceeds the system set value, so as to keep the water quality and temperature in the liquid supply device in an ideal range.

[0047] In a specific application scenario, first place the material 4 to be cooled on the pressing layer, and drive each pressing plate 1 to move along the height extension direction of the frame through the driving component to press the materials 4 to be cooled. Then, turn on the driving pump, and the driving pump drives the cooling medium in the liquid supply device to flow through the filter valve 20, the first pressure sensor 26, the electric stop valve 24, the second pressure sensor 27, and the proportional flow regulating valve 23 in sequence, and then enter the fluid channel 11 from the liquid inlet 110 and flow out from the liquid outlet 111 to cool the materials 4 to be cooled in each pressing layer. If it is necessary to adjust the cooling temperature of the material 4 to be cooled, the controller is used to control the opening degree of the proportional flow regulating valve 23, so as to control the flow rate of the cooling medium passing through the fluid channel 11 to control the temperature of the material 4 to be cooled;

[0048] The cooling medium flowing out from the liquid outlet 111 flows back to the liquid supply device after passing through the third pressure sensor 28 and the solenoid valve 25. During this process, when the material has a heat preservation requirement, the controller is used to control the solenoid valve 25 to close. If the pressure of the cooling system 2 exceeds the pressure set by the safety overflow valve 29, the controller is used to control the safety overflow valve 29 to open, so that the cooling medium flows back to the liquid supply device from the safety overflow valve 29. When the return water temperature exceeds the system set value, the heat exchanger is used to exchange heat for the cooling medium to reduce the temperature of the returned cooling medium and keep the water quality and temperature of the liquid supply device in the ideal range;

[0049] After cooling, drive each pressing plate 1 to move along the height extension direction of the frame through the driving component, so that each pressing plate 1 returns to its original position, and then use the transport trolley to transport the cooled materials in each pressing layer to the next process.

[0050] As described above, it is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the technical field of the present application within the technical scope disclosed by the present application should be covered by the protection scope of the present application.
