Description

Technical Field

[0001] The present invention relates to the technical field of air-cooled rollers, and particularly to a wrapped air-cooled roller for an odor remover. Background Art

[0002] Automobile leather is a comfortable, beautiful, hygienic and durable material, which is deeply loved by people. Leather is made from natural cowhide through tanning and finishing processes, and chemical materials such as synthetic oils and polyurethane resins will be used during the processing. Due to the complexity of the processing technology and the limitations of existing chemical materials, the finished leather will have the typical leather odor problem. In order to improve the consumer experience, it is necessary to deodorize the leather fabric. Most of the existing deodorizing equipment makes the odor molecules in the leather fabric dissipate in the form of hot air.

[0003] After the leather fabric is deodorized by hot air, it needs to be cooled again to avoid direct winding and heat accumulation, which may cause burns to the fabric. In the existing treatment methods, the fabric is first air-cooled and then water-cooled, that is, the fabric is wound around the air-cooled roller and the water-cooled roller. However, the existing air-cooling method is positive pressure, that is, air is pumped into the roller body, and then the air is sent out from the air holes for cooling the fabric. When using this method, especially for leather fabrics, there is a gap between the leather and the air-cooled roller, which is not conducive to the transmission of the fabric by the roller body. At this time, a greater pulling force is required to pull the fabric, which not only makes the fabric subject to excessive force; when the fabric is subject to excessive force, the gap between the fabric and the air-cooled roller decreases, which is not conducive to cooling. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a wrapped air-cooled roller for an odor remover, including a support frame, on which a plurality of air-cooled rollers and water-cooled rollers are provided. The air-cooled roller includes a roller body, and a plurality of air holes are provided on the side wall of the roller body. Both ends of the roller body are fixedly connected with hollow shafts, and the ends of the hollow shafts are communicated with a negative pressure device. The existing air-cooled roller cools the fabric by positive pressure, that is, air is pumped into the roller body, and then the air is sent out from the air holes for cooling the fabric. When using this method, especially for leather fabrics, there is a gap between the leather and the air-cooled roller, which is not conducive to the transmission of the fabric by the roller body. At this time, a greater pulling force is required to pull the fabric, which not only makes the fabric subject to excessive force; when the fabric is subject to excessive force, the gap between the fabric and the air-cooled roller decreases, which is not conducive to cooling. Generally speaking, too small a gap is not conducive to cooling, and too large a gap is not conducive to fabric transportation.

[0005] In this solution, a negative pressure method is adopted, and the fabric is adsorbed on the roller body, which is conducive to transportation and can also achieve cooling. At the same time, the negative pressure structure can suck away the residual odor molecules on the fabric, reducing the impact on the production line environment.

[0006] Preferably, a tensioning frame is fixedly connected to one side of the support frame, and guide rollers are arranged at the corners of the tensioning frame. The fabric is tensioned before being fed into the support frame to avoid problems such as wrinkles in the fabric during the cooling process.

[0007] Preferably, a swing arm is rotatably connected to the middle of one side of the tensioning frame. A first tensioning roller is rotatably connected to the end of the swing arm. A cylinder is arranged above the swing arm. The upper end of the cylinder is rotatably connected to the tensioning frame, and the downward extending output end of the cylinder is rotatably connected to the swing arm. The fabric passes upward from below the first tensioning roller, and the cylinder controls the inclination angle of the swing arm, that is, controls the height of the first tensioning roller to achieve the tensioning of the fabric.

[0008] Preferably, two second tensioning rollers are arranged in the middle of the upper end of the tensioning frame, and both ends are rotatably connected to the connecting piece. The connecting piece and the tensioning frame are rotationally matched, and a disc spring is arranged between them. Under the action of the disc spring, the two second tensioning rollers rotate, that is, fold the fabric passing between them, so as to achieve the tensioning effect. This setting limits the fabric tension from being too large or too small, and combines components such as cylinders and tensioning collars to meet the requirements of fabric tension control during the production process.

[0009] Preferably, the output end of the negative pressure device is connected to the input end of the purification device. The gas is purified.

[0010] The beneficial effects of the present invention are as follows: 1. The fabric is adsorbed on the air-cooling roller by means of negative pressure, which is not only conducive to the cooling treatment of the fabric, but also conducive to the transmission of the fabric by the air-cooling roller.

[0011] 2. By means of negative pressure, the odor molecules remaining on the fabric are sucked away as much as possible, reducing the impact on the production line environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0015] As Figures 1 to 2 shown, a wrapped cold air roller of an odor eliminator includes a support frame 7, which is a rectangular frame composed of several rods. A plurality of air-cooled rollers 8 and water-cooled rollers 9 are arranged on the support frame 7. The fabric first passes through the air-cooled rollers 8 and then is further cooled by the water-cooled rollers 9. Cold water flowing is injected into the interior of the water-cooled rollers 9. In addition, a plurality of shaft rods are arranged on the support frame 7 for guiding the fabric, so as to maximize the wrap angle between the fabric and the air-cooled rollers 8 as much as possible. The air-cooled roller 8 includes a roller body 82, and a plurality of air holes 83 are arranged on the side wall of the roller body 82. Hollow shafts 81 are fixedly connected to both ends of the roller body 82, and the ends of the hollow shafts 81 are communicated with a negative pressure device, that is, the interior of the roller body 82 is also in a negative pressure state. Air is adsorbed through the air holes 83. During the process, the fabric is cooled, and at the same time, in the negative pressure mode, the fabric is adsorbed on the surface of the roller body 82.

[0016] A tensioning frame 5 is fixedly connected to one side of the support frame 7, and a guide roller 4 is arranged at the corner of the tensioning frame 5. The guide roller 4 facilitates the conveying of the fabric.

[0017] A swing arm 2 is rotatably connected to the middle of one side of the tensioning frame 5, and a first tensioning roller 1 is rotatably connected to the end of the swing arm 2. The fabric 1 passes upward from below the first tensioning roller 1. A cylinder 3 is arranged above the swing arm 2. The upper end of the cylinder 3 is rotatably connected to the tensioning frame 5, and the downward extending output end of the cylinder 3 is rotatably connected to the swing arm 2. When the cylinder 3 works, its output end extends or retracts, thereby changing the inclination angle of the swing arm 2, and further changing the tension of the fabric.

[0018] Two second tensioning rollers 6 are arranged in the middle of the upper end of the tensioning frame 5. The fabric passes between the two second tensioning rollers 6, and both ends are rotatably connected to a connecting member. The connecting member is rotatably matched with the tensioning frame 5, and a disc spring is arranged between the two. Under the action of the disc spring, the two second tensioning rollers 6 deflect, and then the tension of the fabric is realized. At this time, this setting avoids the fabric being stressed too much or too little.

[0019] The output end of the negative pressure device is connected to the input end of the purification equipment. The extracted gas is purified, which has the advantage of being green and environmentally friendly.

[0020] The technical means disclosed by the solution of the present invention are not limited to the technical means disclosed in the above embodiments, and also include technical solutions composed of any combination of the above technical features.
