Description

Technical Field

[0001] The utility model relates to the technical field of textile drying, in particular to a textile cold drying device. Background Art

[0002] When textiles are produced, the moisture in the textiles needs to be dried. During the drying stage, cold drying or hot drying is used. Cold drying is less harmful to textiles than hot drying. Cold drying generates dry cold air through a heat exchange device. The dry air enters the cold drying box to dry the textiles, and the moisture on the textiles is absorbed by the dry cold air.

[0003] For example, a Chinese patent document with patent application number "CN212974668U" discloses an energy-saving and environmentally friendly cold dryer for non-woven fabric production and processing, which passes the non-woven fabric through one through hole and then out of another through hole, and places the non-woven fabric between two pressing rollers, and then the cold dryer body can condense and dry the non-woven fabric, and then the non-woven fabric is dried and rolled up in turn. In this way, the cold dryer body is located below the non-woven fabric, and the cold air can only blow to the lower side of the non-woven fabric, the wind is uneven, and the cooling time of the non-woven fabric in the cooling chamber is short, resulting in poor cooling effect of the non-woven fabric.

[0019] Reference Figures 1 to 4 The utility model provides an embodiment of a textile cold drying device.

[0020] A textile cold drying device comprises an outer shell 1, one side of which is hinged with a sealing door 2. The sealing door 2 on the outer shell 1 is used to seal the interior to prevent dry cold air from diffusing and losing, thereby ensuring the cold drying effect.

[0021] An inner shell 3 is provided inside the outer shell 1, and a flow equalization chamber 4 is provided between the inner shell 3 and the outer shell 1. A first cold air inlet pipe 51 is provided on the flow equalization chamber 4, and the first cold air inlet pipe 51 is connected to the air inlet main pipe, and the air inlet main pipe is connected to the heat exchange device. A plurality of air distribution ports 31 are provided on the inner shell 3, and the dry cold air entering from the first cold air inlet pipe 51 can be evenly distributed and evenly enter the inner shell 3 from the air distribution ports 31, so that the dry cold air inside the inner shell 3 can be evenly blown toward the textile cloth, thereby preventing the dry cold air from being concentrated in a certain place and the strong wind from damaging the textile cloth. An air outlet 33 is also provided in the middle of the upper side of the inner shell 3, and a wind collecting hood 34 is provided on the air outlet 33. The wind collecting hood 34 is connected to the exhaust pipe 35, and the exhaust pipe 35 is connected to the heat exchange device. The heat exchange device is a prior art, including a compressor, a steam engine, a condenser, a steam-water separator and an automatic drain valve. The compressor converts the refrigerant into high-temperature and high-pressure refrigerant steam, and the high-temperature refrigerant steam is cooled in the condenser to become a low-temperature and low-pressure liquid refrigerant. The liquid refrigerant is vaporized at the evaporator, and the air with water vapor entering from the exhaust pipe 35 is dried and cooled. After the water vapor is removed and the air is cooled to become dry cold air, it enters the air inlet main pipe and is introduced into the flow equalization cavity 4 and the air distribution duct 7.

[0022] A plurality of guide rollers 6 extending toward the sealing door 2 and a first groove 32 corresponding to the horizontal direction of the guide roller 6 are rotatably provided on a side wall of the inner shell 3 away from the sealing door 2. The first groove 32 and the guide roller 6 are staggered left and right. An air distribution pipe 7 is slidably provided in the first groove 32. A plurality of cold air holes 71 are provided on the peripheral wall of the air distribution pipe 7. The guide roller 6 is used to guide the textile cloth, and the first groove 32 is used to slide with the air distribution pipe 7. The first groove 32 and the guide roller 6 are staggered left and right, which increases the time the textile cloth spends in the inner shell 3 and improves the cold-drying effect. At the same time, the air distribution pipe 7 moves back and forth at the bending part of the textile cloth, sprays uniform dry cold air to the textile cloth, and can blow to both sides of the textile cloth, further improving the cold-drying effect.

[0023] A drive box 8 is further provided on the side of the outer shell 1 away from the sealing door 2, and a support baffle 81 is provided in the drive box 8, and a second groove 811 corresponding to the first groove 32 is provided on the support baffle 81, and a first rack 82 is slidably matched on the second groove 811, and the first rack 82 can slide in the axial direction of the second groove 811. Specifically, a guide block 812 is slidably provided in the second groove 811, and a ball 813 is provided on the upper and lower end surfaces of the guide block 812, and a guide groove 814 matched with the ball 813 is provided on the side wall of the second groove 811, and the first rack 82 is fixed to the guide block 812.

[0024] The teeth of each two groups of the first racks 82 are arranged opposite to each other and mesh with a transmission gear 83 at the same time, wherein one transmission gear 83 is connected to the output end of the driving motor 84, wherein the driving motor 84 can be a servo motor or a reduction motor, and the transmission gear 83 is also provided with a transmission sprocket 85, and multiple transmission sprockets 85 are driven by a chain 86. A connecting pipe 821 is also fixed on each of the first racks 82, and two adjacent connecting pipes 821 are arranged alternately on the two groups of first racks 82. Each of the connecting pipes 821 is connected to the second cold air inlet pipe 52 through a flexible pipe 521, and the second cold air inlet pipe 52 is connected to the main air inlet pipe. The second cold air inlet pipe 52 is provided with a branch pipe joint, and several flexible pipes 521 are connected to the second cold air inlet pipe 52 through the branch pipe joint, and one end of the connecting pipe 821 passes through the second groove 811 and is fixed to one end of the air distribution pipe 7. One of the transmission gears 83 rotates under the drive of the driving motor 84, and synchronously drives the other transmission gears 83 to rotate synchronously through the chain 86. One transmission gear 83 can drive the two racks meshing with it to move in opposite directions, and then drive the two connecting tubes 821 thereon to move relative to each other or move away from each other, that is, drive each air distribution tube 7 to move toward the guide roller 6 or away from the guide roller 6 at the same time, that is, the upper and lower air distribution tubes 7 are staggered to perform all-round cold drying on the textile cloth, thereby ensuring the cold drying effect and improving the cooling efficiency and cooling uniformity of the textile cloth.
