Description

Technical Field

[0001] This utility model belongs to the field of supercritical foaming board processing technology, and in particular relates to a cooling and shaping equipment for supercritical foaming board processing. Background Technology

[0002] The supercritical foam board processing cooling and shaping equipment is one of the core devices in the supercritical foam board production line. It is mainly used to force-cool and solidify the foamed board and calibrate its size and shape to obtain a finished board with a stable cell structure, accurate dimensional accuracy and ideal physical properties. Its function runs through the key transformation stage of the board from the molten foamed state to the solid shaped state, and directly determines the quality of the board and the production efficiency.

[0003] The supercritical foam board processing cooling and shaping equipment mainly consists of a shaping mold cavity, a cooling circulation system, a transmission device, a temperature monitoring system, and a pressure regulating device. The transmission device transports the initially formed board to the cooling and shaping mold cavity. During the transport process or before entering the mold cavity, the surface of the board is rapidly cooled by the pre-cooling device to suppress excessive expansion of the foam cells and stabilize the initial shape.

[0004] Currently, in the traditional cooling and shaping process of existing technologies, when the foamed board is directly put into the cooling and shaping mold cavity, the high temperature will cause the internal foaming agent gas to be highly active, and the foam cells are prone to excessive expansion and rupture. In addition, the high temperature will generate thermal shock to the shaping mold cavity, which will increase the cooling load and affect the life and stability of the equipment. Although traditional equipment uses water cooling or air cooling for initial cooling, water cooling is affected by factors such as water quality and heat dissipation, resulting in large temperature fluctuations of the medium and easy seepage of condensate into the foam cells. At the same time, air cooling has low thermal conductivity and requires a significant increase in airflow to effectively cool down, thus affecting the processing efficiency of the board.

[0005] To address the aforementioned issues, this application proposes a supercritical foaming board processing, cooling, and shaping device. Utility Model Content

[0006] The purpose of this invention is to provide a cooling and shaping device for supercritical foaming board processing, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a supercritical foaming board processing, cooling, and shaping equipment, comprising a support frame, a conveyor belt rotatably connected to the inner wall of the support frame, a rotating motor disposed on the left side of the support frame, the power output end of the rotating motor being fixedly connected to the transmission end of the conveyor belt, a controller being fixedly connected to the left side of the support frame, a first connecting frame and a second connecting frame being fixedly connected to the upper surface of the support frame, an exhaust pump disposed above the second connecting frame, two exhaust plates disposed inside the second connecting frame, the input end of the exhaust pump penetrating the second connecting frame and being fixedly connected to the upper surface of the exhaust plates, a temperature sensor being snapped into the inner wall of the first connecting frame, a refrigeration unit being fixedly connected to the upper surface of the first connecting frame, a refrigeration pipe rack disposed inside the first connecting frame, and the output end of the refrigeration unit penetrating the first connecting frame and being fixedly connected to the outer surface of the refrigeration pipe rack.

[0009] Furthermore, two sets of support columns are fixedly connected to the bottom surface of the support frame, and a support ring is fixedly connected to the bottom end of each support column.

[0010] Furthermore, a support base is fixedly connected to the bottom surface of the rotating motor, and the right side of the support base is fixedly connected to the left side of the support frame.

[0011] Furthermore, a fixing frame is fixedly connected to the bottom surface of the exhaust pump, and the bottom surface of the fixing frame is fixedly connected to the upper surface of the second connecting frame.

[0012] Furthermore, each of the exhaust panels has two reinforcing frames fixedly connected to its outer surface, and the upper surfaces of both sets of reinforcing frames are fixedly connected to the inner top wall of the second connecting frame.

[0013] Furthermore, a reinforcing ring is fixedly connected to the outer surface of the temperature sensor, and the bottom surface of the reinforcing ring is fixedly connected to the upper surface of the first connecting frame.

[0014] Furthermore, a connecting plate is fixedly connected to the outer surface of the refrigeration tube rack, and the two connecting plates are fixedly connected to the inner wall of the first connecting frame on opposite sides.

[0015] This utility model has the following beneficial effects:

[0016] This invention sets up a continuous transmission system by setting up a rotating motor, support frame, and conveyor belt to work together. This system can stably transport the foamed board to be cooled, ensuring that the board enters the cooling area at a uniform speed. This effectively avoids the problem of uneven cooling caused by transmission jams. At the same time, by using an exhaust pump, exhaust plate, and second connecting frame in conjunction, a negative pressure exhaust channel is formed during the board transport process. The heat on the surface of the board is quickly removed by forced convection, thereby achieving initial cooling and inhibiting excessive expansion of the foam cells at high temperatures.

[0017] This invention, by setting up a refrigeration unit, works in conjunction with a temperature sensor, refrigeration tube rack, controller, and first connecting frame to create a low-temperature space with precise temperature control. In this way, a stable low-temperature zone can be formed within the first connecting frame to deeply cool the sheet material. This design can not only quickly reduce the core temperature of the sheet material to below the glass transition temperature of the polymer, but also reduce the thermal shock of the high-temperature sheet material to the cooling and shaping equipment by utilizing the low-temperature environment, thereby extending the service life of the mold and significantly improving processing efficiency.

[0018] In summary, by deeply integrating transmission and conveying, negative pressure exhaust pre-cooling, and precise temperature control and cooling, an innovative solution for cooling supercritical foamed boards has been constructed. The transmission system ensures uniform conveying of the boards, avoiding uneven cooling caused by transmission fluctuations. The negative pressure exhaust pre-cooling structure quickly removes heat from the surface of the boards, inhibiting excessive deformation of the foam cells at high temperatures. The intelligent temperature control system achieves deep cooling of the boards through the coordinated operation of the refrigeration unit and sensors, reducing the thermal erosion of the equipment by high temperatures. This equipment solves the problems of temperature runaway, high equipment wear and tear, and low production efficiency in traditional processes.

It has the characteristics of high reliability, strong anti-interference ability and easy programming, and is widely used in mechanical manufacturing, chemical industry, power and metallurgy. Meanwhile, the refrigeration unit 14 is mainly composed of a compressor, condenser, throttling device and evaporator components.

[0032] Two sets of support columns 8 are fixedly connected to the bottom surface of the support frame 1. Each support column 8 has a support ring 9 fixedly connected to its bottom end. In this embodiment, the support column 8 can fix the support ring 9 to the support frame 1, and the support ring 9 can be used to make the support frame 1 stable.

[0033] The bottom surface of the rotating motor 6 is fixedly connected to a support base 7, and the right side of the support base 7 is fixedly connected to the left side of the support frame 1. In this embodiment, the rotating motor 6 can be fixed to the support frame 1 through the support base 7, thereby making the rotating motor 6 sturdy.

[0034] The bottom surface of the exhaust pump 11 is fixedly connected to the fixing frame 10, and the bottom surface of the fixing frame 10 is fixedly connected to the upper surface of the second connecting frame 4. In this embodiment, the exhaust pump 11 and the second connecting frame 4 can be fixed by the fixing frame 10, and the exhaust pump 11 can be used stably.

[0035] Each exhaust plate 13 has two reinforcing frames 12 fixedly connected to its outer surface. The upper surfaces of the two sets of reinforcing frames 12 are fixedly connected to the inner top wall of the second connecting frame 4. In this embodiment, the exhaust plate 13 can be fixed to the second connecting frame 4 through the reinforcing frames 12, so that the exhaust plate 13 can be used stably.

[0038] Understandably, the rotating motor 6, support frame 1, and conveyor belt 3 ensure uniform conveying of the board material. At the same time, the exhaust pump 11, in conjunction with the exhaust plate 13 and the second connecting frame 4, achieves rapid pre-cooling through negative pressure convection, suppressing cell deformation. Furthermore, the refrigeration unit 14, in collaboration with the temperature sensor 15, controller 5, and first connecting frame 2, further cools the foamed board, thereby solving problems such as high equipment wear during the cooling and shaping of the foamed board, and improving processing efficiency and product quality.

[0039] A specific application of this embodiment is as follows: In use, firstly, the support frame 1 is securely installed in the designated position on the production line using the support column 8 and support ring 9. Simultaneously, the power supply to the rotary motor 6, refrigeration unit 14, temperature sensor 15, exhaust pump 11, and controller 5 is connected, and equipment linkage debugging is completed. Then, the rotary motor 6 is started via controller 5, causing the conveyor belt 3 to carry the foamed board from the right side of the support frame 1 into the cooling area. Simultaneously, as it passes under the second connecting frame 4, the exhaust pump 11 starts synchronously, forming a negative pressure exhaust channel within the second connecting frame 4 through the exhaust plate 13. At the same time, the forced convection principle is used to quickly remove heat from the surface of the board, inhibiting foaming. The pores expand excessively at high temperatures, completing the initial cooling. Then, the board material enters the area below the first connecting frame 2 along the conveyor belt 3. Temperature data of this area is collected in real time by the temperature sensor 15 and transmitted to the controller 5. At the same time, the controller 5 automatically adjusts the output power of the refrigeration unit 14 and releases cold air in conjunction with the refrigeration pipe rack 17 according to the deviation between the preset temperature and the actual temperature, thereby reducing the temperature of the core of the board material and reducing the thermal shock of the board material to the subsequent shaping device. Finally, the cooled board material is transported by the conveyor belt 3 to the downstream cooling and shaping device. By reducing the thermal shock of the foamed board to the shaping device at low temperature, the thermal shock of the foamed board to the shaping device is reduced, further reducing equipment wear and improving cooling efficiency and finished product accuracy.
