DETAILED DESCRIPTION

[0033] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0034] Water-based PU leather cooling device, refer to Figure 1 、 Figure 2 and Figure 3 , including a support plate 1, a lower plate 2 is provided on one side of the support plate 1, a cooling roller 3 is provided above the support plate 1, vertical plates 11 are fixed on both sides of the upper end of the support plate 1, and the two ends of the cooling roller 3 are rotatably connected to the corresponding two vertical plates 11, and the outer end of the vertical plate 11 on one side of the support plate 1 is connected to a motor 12 through four bolts, the output end of the motor 12 passes through the vertical plate 11 and is fixedly connected to the cooling roller 3, the support plate 1 serves as a connection carrier, and the motor 12 drives the cooling roller 3 to rotate between the two vertical plates 11, providing power assistance for the movement of the PU leather.

[0035] Reference Figure 2 One end of the vertical plate 11 located on one side of the cooling roller 3 is provided with a matching groove 14 used to cooperate with the output end of the motor 12. A guard plate 13 is fixed to the outer end of the vertical plate 11 located on one side of the cooling roller 3, and the lower end of the corresponding motor 12 is connected to the guard plate 13 by bolts. The matching groove 14 improves the driving stability of the motor 12, and the guard plate 13 protects and supports the motor 12, so that the rotation effect of the cooling roller 3 is better.

[0036] Reference Figure 2 and Figure 3 , transmission shafts 4 are rotatably provided on both sides of the upper end of the lower plate 2, three vertical rods 21 are fixed at both ends of the support plate 1, and an upper plate 22 is fixed on the upper side of the inner end of the six vertical rods 21. The transmission shaft 4 is between the upper plate 22 and the lower plate 2. After passing through the cooling roller 3, the substrate enters the cooling channel formed between the upper plate 22 and the lower plate 2 and is guided by the transmission shaft 4.

[0037] Reference Figure 1 and Figure 3Three cooling blowers 5 are provided above the upper plate 22. An air inlet pipe 51 is provided at one end of the cooling blower 5, and a filter 52 is fixedly provided on the upper side of the inner wall of the air inlet pipe 51. Three through slots 53 are provided on the upper end of the upper plate 22 for use with the output ends of the cooling blowers 5. When the water-based PU leather cooling device is in operation, the PU leather moves smoothly between the upper plate 22 and the lower plate 2 under the guidance of the two transmission shafts 4. During the movement of the PU leather, the cooling blower 5 starts to work, sucking air through the air inlet pipe 51. After the filter 52 filters out impurities in the air, the cooling air is blown from the output end of the cooling blower 5 through the through slots 53 on the upper plate 22 to cool the PU leather. The two transmission shafts 4 guide the PU leather to ensure that the PU leather can move stably during the cooling process, thereby improving the uniformity of the cooling effect. In addition, through the coordinated work of multiple cooling blowers 5, sufficient cooling air can be provided to the PU leather, thereby improving the cooling efficiency and achieving stable transmission while performing cooling work.

[0038] Reference Figure 4 and Figure 5 , one end of the mounting block 54 is embedded with a water tank 7, and a water adding pipe 71 is fixedly provided at the upper end of the water tank 7, and a pipe cover 72 is provided at the upper end of the water adding pipe 71. The lower end of the water tank 7 is connected to a water pump 73. The output end of the water pump 73 passes through the upper plate 22 and is fixedly provided with an atomizing nozzle 74. One end of the mounting block 54 is provided with a placement groove 75 for use with the water tank 7 and the water pump 73. There is water in the water tank 7. When the pipe cover 72 is opened, water can be added to the tank through the water adding pipe 71. Before the PU leather is cooled, the water pump 73 is started to make the atomizing nozzle 74 spray out part of the water and fall on the PU leather. In combination with air cooling, the cooling efficiency of air cooling alone is relatively low, and spraying water on the surface of the water-based PU leather can use the high specific heat capacity of water to quickly absorb heat, so that the temperature of the water-based PU leather drops rapidly. At the same time, air cooling can accelerate the evaporation of water and further take away heat. The combination of the two can significantly improve the cooling speed and efficiency.

[0039] Reference Figure 3 A mounting block 54 is fixedly provided on one side of the upper end of the upper plate 22, and a slider 55 is fixedly provided on one end of the cooling blower 5. Three slide grooves 56 for cooperating with the slider 55 are opened at one end of the mounting block 54. The slider 55 is slid into the slide groove 56 in the mounting block 54 to realize the installation of the cooling blower 5. The installation is convenient and the installation stability is high.

[0040] Reference Figure 2 and Figure 3 , connecting plates 8 are fixed on both sides of one end of the lower plate 2, and the two connecting plates 8 are connected to one of the support plates 1 by bolts. The two connecting plates 8 with corresponding positions are mirror-imaged, and the cross-sectional shape of the connecting plate 8 is "L"-shaped. One of the support plates 1 and the lower plate 2 are fixedly connected by the connecting plate 8 to form a cooling device unit.

[0041] Reference Figure 6 , an insert plate 61 is fixedly provided at one end of the lower plate 2 away from the connecting plate 8, and a mounting frame 6 is fixedly provided on one side of the lower end of the support plate 1. A plate groove 62 is opened at one end of the mounting frame 6 to cooperate with the insert plate 61, and both ends of the mounting frame 6 and the corresponding insert plate 61 are connected by bolts. When multiple cooling device units are needed to be spliced, the insert plate 61 at the end of the lower plate 2 of one unit away from the transmission shaft 4 is inserted into the plate groove 62 of the mounting frame 6 on the lower end side of the support plate 1 of another unit, and then fixed with bolts to achieve splicing of multiple units. Different numbers of cooling structures can be flexibly installed according to cooling needs to meet different cooling requirements.

[0042] Working principle: The support plate 1 serves as a connecting carrier, and the motor 12 drives the cooling roller 3 to rotate between the two vertical plates 11, providing power assistance for the movement of the PU leather; the stability of the motor 12 drive is improved by the matching groove 14, and the motor 12 is protected and supported by the guard plate 13, so that the rotation effect of the cooling roller 3 is better.

[0043] When the water-based PU leather cooling device is working, the PU leather moves smoothly between the upper plate 22 and the lower plate 2 under the guidance of the two transmission shafts 4. During the movement of the PU leather, the cooling blower 5 starts to work, and air is sucked in through the air inlet pipe 51. After the filter 52 filters out impurities in the air, the cooling air is blown from the output end of the cooling blower 5 through the through groove 53 on the upper plate 22 to cool the PU leather. The two transmission shafts 4 guide the PU leather to ensure that the PU leather can move stably during the cooling process, thereby improving the uniformity of the cooling effect. In addition, through the coordinated work of multiple cooling blowers 5, sufficient cooling air can be provided for the PU leather, thereby improving the cooling efficiency and achieving stable transmission while performing cooling work.

[0044] There is water in the water tank 7. By opening the pipe cover 72, water can be added to the tank through the water filling pipe 71. Before the PU leather is cooled, the water pump 73 is started to allow the atomizing nozzle 74 to spray some water, which falls on the PU leather and is cooled with air cooling. The cooling efficiency of air cooling alone is relatively low, while spraying water on the surface of the water-based PU leather can use the high specific heat capacity of water to quickly absorb heat, so that the temperature of the water-based PU leather drops rapidly. At the same time, air cooling can accelerate the evaporation of water and further take away heat. The combination of the two can significantly improve the cooling speed and efficiency.

[0045] The sliding block 55 is slid into the sliding groove 56 in the mounting block 54 to realize the installation of the cooling blower 5 , which is convenient to install and has high installation stability.

[0046] One of the support plates 1 and the lower plate 2 are fixedly connected by the connecting plate 8 to form a cooling device unit. When multiple cooling device units need to be spliced, the plug-in plate 61 at the end of the lower plate 2 of one unit away from the transmission shaft 4 is inserted into the plate groove 62 of the mounting frame 6 on the lower end side of the support plate 1 of another unit, and then fixedly connected with bolts to realize the splicing of multiple units. Different numbers of cooling structures can be flexibly installed according to the cooling needs to meet different cooling requirements.
