Description

Technical Field

[0001] The utility model relates to the technical field of pre-shrinking machines, and more specifically, to a wet-dry integrated pre-shrinking machine. Background Art

[0002] At present, during the dyeing and finishing process of fabrics, the hydrophilic fibers will increase their buckling wave height when wetted with water, and the length of the fabric will be shortened to form shrinkage. The percentage of this shortening of the fabric to the original length is called shrinkage rate. Therefore, the fabrics need to be pre-shrunk after dyeing and finishing, that is, the warp and weft density of the fabrics are increased to leave enough space between the warp and weft to offset the potential shrinkage of the fabrics and prevent the fabrics from shortening in length when the fibers swell after being wetted. The pre-shrinking machine used for fabrics adopts physical and mechanical methods.

[0003] When the existing pre-shrinking machine is working, it is usually necessary to spray high-temperature steam on the surface of the fabric, but the conventional nozzle can only perform local humidification, which causes the fabric to be heated and contacted with the steam unevenly, resulting in unsatisfactory pre-shrinking of the fabric.

[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a wet-dry integrated preshrinking machine.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a wet-dry integrated preshrinking machine, including a preshrinking machine body, on which a feed roller group, a humidifying component, a drying component and a discharge roller group are sequentially arranged, the humidifying component includes a humidifying plate, a cavity is opened inside the humidifying plate, a plurality of exhaust holes are evenly opened on the surface of the humidifying plate, an air inlet hole is opened at the bottom of the humidifying plate and is connected to a steam inlet pipe, and a sealing cover is arranged on the surface of the preshrinking machine body and above the humidifying plate.

[0007] By adopting the above technical solution, after the fabric enters the preshrinking machine body through the feed roller group, its surface is humidified by the humidifying component, steam enters the cavity through the steam inlet pipe, and is evenly discharged from the cavity through the exhaust hole and blown toward the fabric. The steam can evenly blow the fabric, thereby evenly humidifying and heating the fabric, thereby improving the preshrinking effect of the fabric.

[0008] The utility model is further configured as follows: an H-shaped exhaust component is arranged inside the cavity, and the exhaust component includes a horizontal pipe and two vertical pipes connected to the two ends of the horizontal pipe, a connecting pipe connected to the air inlet is connected to the middle of the horizontal pipe, and a plurality of air outlet holes are evenly opened on the surface of the vertical pipe.

[0009] The utility model is further configured as follows: a heating element is arranged in the cavity, specifically an electric heating tube evenly distributed in the cavity along an S shape.

[0010] The utility model is further configured as follows: a drainage hole is opened at the center of the humidifying plate, a drainage pipe connected to the drainage hole is arranged at the bottom of the humidifying plate, and the bottom surface of the cavity is inclined toward the center.

[0011] The utility model is further configured as follows: two air inlet holes are provided at the bottom of the humidifying plate and are arranged on both sides of the drainage hole, and exhaust components are arranged on the air inlet holes.

[0012] The utility model is further configured as follows: an air suction port is opened on the top of the sealing cover, and an exhaust fan is arranged at the top of the sealing cover at the air suction port.

[0023] As shown in the figure, a wet-dry integrated preshrinking machine includes a preshrinking machine body 1, on which a feed roller group 2, a humidifying assembly 3, a drying assembly 4 and a discharge roller group 5 are sequentially arranged, the humidifying assembly 3 includes a horizontally arranged humidifying plate 6, a cavity is opened inside the humidifying plate 6, a plurality of exhaust holes 7 are evenly opened on the surface of the humidifying plate 6, an air inlet hole 8 is opened at the bottom of the humidifying plate 6 and connected to a steam inlet pipe 9, and a sealing cover 10 is arranged on the surface of the preshrinking machine body 1 and above the humidifying plate 6. The drying assembly 4 is a prior art and will not be described in detail in this embodiment.

[0024] After the fabric passes through the feed roller group 2 and enters the shrinking machine body 1, the surface of the fabric is humidified by the humidifying component 3. The steam enters the cavity through the steam inlet pipe 9 and is evenly discharged from the cavity through the exhaust hole 7 and blown toward the fabric. The steam can blow the fabric evenly, thereby evenly humidifying and heating the fabric, thereby improving the preshrinking effect of the fabric.

[0025] An H-shaped exhaust member 11 is arranged inside the cavity, and the exhaust member 11 includes a transverse pipe 12 and two vertical pipes 13 connected to the two ends of the transverse pipe 12. A connecting pipe 14 connected to the air inlet 8 is connected to the middle of the transverse pipe 12. A plurality of air outlet holes (not shown in the figure) are evenly opened on the surface of the vertical pipe 13. Steam enters the exhaust member 11 through the air inlet 8, and can enter the cavity evenly through the air outlet holes on the transverse pipe 12 and the vertical pipe 13, thereby further improving the uniformity of steam discharge from the exhaust hole 7.

[0026] A heating element 15 is provided in the cavity, specifically an electric heating tube evenly distributed in the cavity along an S shape. The electric heating tube can maintain the temperature in the cavity, prevent the steam from liquefying after entering the cavity, and ensure the humidification and heating effect on the fabric.

[0027] A drainage hole 16 is provided at the center of the humidifying plate 6, and a drainage pipe 17 connected to the drainage hole 16 is provided at the bottom of the humidifying plate 6. The bottom surface of the cavity is inclined toward the center. When part of the water vapor is liquefied, the liquefied water can be discharged from the exhaust hole 7 to prevent water accumulation inside the cavity.

[0028] Two air inlet holes 8 are provided at the bottom of the humidifying plate 6 and are arranged on both sides of the drainage hole 16. The air inlet holes 8 are each provided with an exhaust member 11 to further improve the uniformity of steam entering the cavity.

The top inner wall of the sealing cover 10 is provided with connecting pieces 20 fixedly connected at both sides of the air extraction port 18, and a wind shield 21 is fixedly connected between the two connecting pieces 20. The exhaust fan 19 is used to recover the excess water vapor, and the wind shield 21 is provided to prevent the exhaust fan 19 from directly acting on the fabric surface, so that the steam enters the exhaust port 18 from both sides of the fabric and is discharged after fully contacting the fabric.

After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed.
