Description

Technical Field

[0001] The utility model belongs to the technical field of cooling devices, in particular to a cooling device for gypsum board molding. Background Art

[0002] Cooling and forming is a crucial step in the production and processing of gypsum board. After forming, the gypsum board must be cooled quickly and evenly to maintain its physical properties and structural stability. Traditional cooling methods rely primarily on contact cooling of the gypsum board by cooling rollers during conveyance. While this method can meet cooling requirements to a certain extent, it has significant limitations.

[0003] Specifically, traditional cooling systems typically only feature one set of cooling rollers, limiting the gypsum board's contact with only one side of the rollers during transport, resulting in single-sided cooling. To achieve dual-sided cooling, a flip mechanism must be incorporated during transport to flip the gypsum board over before it passes through another set of cooling rollers for cooling. This flip cooling method not only complicates the production process, but also suffers from relatively low efficiency, making it a bottleneck on the production line and impacting overall productivity.

[0004] Furthermore, the edges of the gypsum board are prone to dents during the flipping process, which not only damages the board's appearance but can also affect its internal structure, leading to lower product quality. This issue is particularly prominent on high-speed production lines, where the flipping mechanism's movement time and precision often struggle to keep up with high-speed conveying, increasing the risk of product damage.

[0005] It can be seen that there is a certain market demand for designing a new type of cooling device. Summary of the Invention

[0019] In order to better understand the present invention, Figures 1 to 3 The embodiments of the present invention will be explained in detail.

[0020] It should be noted that the directions “front, back, left, right, up, down” mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up and down” are used as the reference.

[0021] The present invention provides a cooling device for gypsum board molding, comprising a housing 1, within which is located a cooling chamber 2. An inlet 3 and an outlet 4 are provided on either side of the housing 1, connecting to the cooling chamber 2. The inlet 3 and outlet 4 interface with the gypsum board conveyor lines of the preceding and subsequent processes, receiving and discharging gypsum boards. Within the cooling chamber 2, a row of cooling conveyor rollers 5 (as used in the prior art) are horizontally arranged, extending from the inlet 3 to the outlet 4, and supporting and moving the gypsum boards during transport.

[0022] The top of the cooling chamber 2 is equipped with several rows of air ducts 6 spaced evenly apart. These outlet ducts 6 are positioned vertically above the cooling conveyor rollers 5. An inlet duct 7 is positioned between each adjacent outlet duct 6, forming an alternating arrangement. A ventilation fan 8, with corresponding direction, is located at the top of each outlet duct 6 and inlet duct 7 to guide airflow between them.

[0023] In particular, the air intake duct 7 is provided with cooling exhaust pipes 9 located below the ventilation fan 8. These cooling exhaust pipes 9 reduce the temperature of the air passing through the air intake duct 7 through the internal cooling medium (such as cooling water or refrigerant). In order to maintain the circulation of the cooling medium between the cooling conveyor roller 5 and the cooling exhaust pipe 9, a first circulation pipe 10 and a second circulation pipe 11 are provided on one side of the outer shell 1. The first circulation pipe 10 is connected in series with all the cooling conveyor rollers 5 for the medium circulation of the cooling conveyor rollers 5; the second circulation pipe 11 is connected in series with all the cooling exhaust pipes 9 for the medium circulation of the cooling exhaust pipes 9. At the same time, a medium circulation mechanism 12 (existing technology, including a circulation pump, a heat exchange module, etc.) is also provided to drive the circulation of the cooling medium.

[0024] To prevent cracking of the gypsum board caused by excessive cooling, the first and second circulation pipes 10 and 11 are connected in parallel at one end near the outlet 4 to form an inlet pipe 13, while the other ends are connected in parallel to form a return pipe 14. This arrangement ensures that the cooling medium continuously flows from the inlet pipe 13 and out of the return pipe 14 during the circulation process. This minimizes the height of the cooling duct 9 and the cooling conveyor roller 5 near the outlet 4, while maintaining a higher temperature near the inlet 3, resulting in a gentler cooling process for the gypsum board.

[0025] The inner walls of both the outlet duct 6 and the inlet duct 7 are equipped with absorbent cotton layers 15. These absorbent cotton layers 15 absorb moisture from the air, preventing condensation from dripping onto the gypsum board and causing quality problems. Furthermore, drainage grooves 16 are provided at the bottom of each duct, matching the absorbent cotton layers 15. A drain pipe is installed at one end of the drainage grooves 16 to drain the absorbed moisture.

[0026] In addition, the housing 1 is equipped with curtains 17 above the inlet 3 and outlet 4. These curtains 17 prevent outside air from directly entering the cooling chamber 2 and affecting the cooling effect. Furthermore, the housing 1 is provided with an air vent connected to the cooling chamber 2. This vent is used for natural ventilation of the cooling conveyor roller 5. A filter plate 18 is installed in the air vent. This filter plate 18 filters out impurities and dust in the air, maintaining the cleanliness of the air in the cooling chamber 2.

[0027] In order to reduce the humidity in the cooling chamber 2, a number of dehumidification boxes 19 are provided at the bottom of the cooling chamber 2. These dehumidification boxes 19 can absorb unnecessary moisture in the cooling chamber 2, keep the dryness of the indoor environment, and further improve the cooling effect.

[0028] How to use:

[0029] First, start the rotation of the cooling conveyor roller 5 and the medium circulation mechanism 12. During this period, as the cooling conveyor roller 5 rotates, the gypsum board is gradually transported into the cooling chamber 2 after being received by the inlet 3. Next, the ventilation fan 8 starts to work, guiding the external air to be input from the air inlet duct 7. The external air becomes cold air under the influence of the cooling exhaust pipe 9. This part of cold air is guided by the air inlet duct 7 to cool the top surface of the gypsum board entering the cooling chamber 2, and after contacting the top surface of the gypsum board, it is quickly discharged through the air outlet 6 and the corresponding ventilation fan 8. At the same time, the bottom surface of the gypsum board is in contact with the cooling conveyor roller 5 to cool down, realizing double-sided cooling of the gypsum board. As the cooling conveyor roller 5 continues to transport, the gypsum board continues to move towards the outlet 4 and is cooled during the process. When the gypsum board is transported to the outlet 4, the cooling is completed and the gypsum board is transported to the next process.
