Description

Technical Field

[0001] The invention relates to the technical field of fabric composites, and in particular to a special gas laminating machine for automobile leather. Background Art

[0002] Fabrics with a single performance often cannot meet the actual use needs, which is beneficial to the decorative fabrics inside the car. For example, the performance of automotive fabrics mainly includes wear resistance, breathability, waterproofness, tear resistance, aging resistance, environmental protection, etc. Therefore, bonding multiple fabrics into composite fabrics is a common practice in the industry to increase the functions of fabrics.

[0003] With the increasing requirements for automotive leather fabrics, such as soft, breathable, and lightweight composite leather, most traditional gas composite mechanisms are equipped with two linked composite rollers and only one fire row. During the production of the composite leather, due to the thermal melting speed of the fabric and its softness, the tension of the fabric is too large or too small, causing the composite fabric to tear or wrinkle stably. In addition, due to the softness of the composite leather, when the composite leather is stored on a traditional storage rack, the wrap angle of the composite leather is large, which is easy to cause damage to the surface of the fabric. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a special gas laminating machine for automobile leather, comprising a gas compounding mechanism, a cooling mechanism and a second material storage rack. That is, the fabric is compounded, then cooled and sent to the second material storage rack.

[0005] The gas compound mechanism includes a main body, a display screen is arranged on one side of the main body, three compound rollers are arranged vertically in sequence on the upper part of the main body, and a driving motor is independently arranged at one end of each compound roller. The driving motor is selected as a high-precision servo motor. Due to the high requirements for automobile leather, such as softness, breathability, and lightness, the automobile leather needs to be thin and soft. Therefore, during compounding, the tension of the leather needs to be strictly controlled. Most traditional gas compound mechanisms are equipped with a pair of compound rollers, and they are linked, that is, they share the same motor. During the compounding process, the leather is stretched by heat and has a soft texture, so wrinkles and other problems appear in the leather compounding process, which seriously affects the quality of the composite fabric.

[0006] In addition, the gas composite mechanism is also provided with two fire bars, which are respectively located on both sides of the composite roller. At the same time, the first fire bar and the uppermost composite roller are arranged at the same height, while the second fire bar and the middle composite roller are arranged at a higher height.

[0007] The second material storage rack includes a frame, and the upper and lower parts of the frame are both provided with vertically movable crossbeams, and a plurality of temporary storage rollers are provided on the crossbeams, and the diameter of the temporary storage rollers is not less than 300 mm, and the spacing between adjacent temporary storage rollers is not less than 800 mm. The temporary storage rollers of this design make the wrap angle of the fabric smaller when it passes by the temporary storage rollers, and the fabric bends less, and will not cause damage to the surface of the fabric.

[0008] Preferably, the cooling mechanism includes several pairs of cooling rollers, the cooling rollers include at least one pair of water-cooled rollers and at least one pair of air-cooled rollers, cold water is passed into the interior of the water-cooled rollers, the surface of the air-cooled rollers is provided with several through holes, and the ends of the air-cooled rollers are connected with air pipes. Since the temperature of the fabric is high after compounding, if it is immediately rolled up and stored, the internal heat accumulation will accelerate the aging of the fabric, and seriously cause the surface of the fabric to change color, so a cooling mechanism is provided for cooling treatment.

[0009] Preferably, two upper and lower feeding conveyor belts are arranged on one side of the gas composite mechanism. The feeding conveyor belts are used for temporary storage of fabrics, facilitating the spreading of fabrics and splicing with new rolls of fabrics. The upper and lower settings make full use of the upper space.

[0010] Preferably, a second unwinding mechanism is provided at one end of the lower conveyor belt, a first storage rack is provided at one end of the upper conveyor belt, the second unwinding mechanism is located below the first storage rack, and the first unwinding mechanism is provided at the other end of the first storage rack. Stable unwinding of the fabric is achieved, making the fabric entering the gas composite mechanism more stable.

[0011] Preferably, a winding mechanism is provided on the other side of the second material storage rack to perform reverse winding operation on the composite fabric.

[0012] The beneficial effects of the present invention are as follows: 1. The gas compound mechanism is provided with three independently driven compound rollers, and the feeding method described in the embodiment can control the conveying speed of the fabric, ensure the constant tension of the fabric, and greatly improve the compound quality of soft leather.

[0013] 2. The temporary storage rollers in the second storage rack have been optimized. Specifically, the diameter of the temporary storage rollers is not less than 300mm and the spacing is not less than 800mm, so that the fabrics passing through are small and it is not easy to produce wrinkles, pitting and other surface quality.

[0014] 3. A cooling mechanism is provided, and cooling treatment is directly performed after the lamination is completed. Compared with the traditional method without such a device, the cooling mechanism can avoid the problem of heat accumulation inside the rolled and stored fabric. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention is further explained 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 are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figures 1 to 3 As shown, a gas laminating machine for automobile leather comprises a gas compound mechanism 5, a cooling mechanism 6 and a second material storage rack 7. The fabric passes through the gas compound mechanism 5, enters the cooling mechanism 6 and is finally sent to the geothermal material storage rack 7.

[0019] The gas compound mechanism 5 includes a main body 52, and a display screen 51 is provided on one side of the main body 52 for displaying the parameters of the fabric compounding, such as the speed of the fabric, the compounding temperature, etc. Three compounding rollers 53 are arranged vertically in sequence on the upper part of the main body 52, and a driving motor is independently provided at one end of each compounding roller 53. The driving motor is a servo motor, and the motor shaft of the servo motor is directly fixedly connected to the compounding roller 53, so as to quickly and accurately control the rotation speed of the compounding roller 53. In addition, a first fire bar and a second fire bar are respectively provided on both sides of the upper part of the main body 52. ​​The fire bar is a pipe with a row of through holes, and the gas is sent out from the through holes and ignited to bake the fabric.

[0020] like Figure 2 As shown, when the gas compound mechanism 5 is working, one fabric enters from the lower left of the main body 52, and the other fabric enters from the upper right of the main body 53, and the two fabrics are laminated and pass through the middle and upper compound rollers 53 together. At this time, the first fire row arranged on the left heats the fabrics, and the two fabrics pass through the middle and lower compound rollers 53 after bypassing the middle compound roller 53. The double heating and the three independently driven compound rollers 53 greatly avoid the occurrence of fabric wrinkles or tears.

[0021] The second material storage rack 7 includes a frame 71, which is composed of at least twelve rods. The upper and lower parts of the frame 71 are both provided with vertically movable crossbeams 72. Here, the upper and lower crossbeams 72 can be arranged in linkage or driven independently. When in linkage, it is preferred to use a bidirectional screw, the two ends of which are respectively threaded with the upper and lower crossbeams 72. By setting a driving unit, the bidirectional bolt is driven to transfer, so that the upper and lower crossbeams 72 are brought closer to or away from each other. A plurality of temporary storage rollers 73 are arranged on the crossbeam 72. The diameter of the temporary storage roller 73 is not less than 300 mm, and the spacing between adjacent temporary storage rollers 73 is not less than 800 mm. In the traditional design, the diameter of the temporary storage roller 73 is about 100 mm and the spacing is 300 mm. It can be as described in the first material storage rack 2 described below. The temporary storage roller 73 has a small diameter and a small spacing, which leads to a large wrap angle between the fabric and the temporary storage roller 73, which is easy to cause problems such as fabric wrinkles and pitting. The temporary storage roller 73 here effectively solves the above problems.

[0022] The cooling mechanism 6 includes several pairs of cooling rollers for cooling the composite fabrics. The cooling rollers include at least one pair of water-cooled rollers and at least one pair of air-cooled rollers. Cold water is passed into the water-cooled rollers. Several through holes are provided on the surface of the air-cooled rollers, and air pipes are connected to the ends of the air-cooled rollers. The composite fabrics are air-cooled in advance and then water-cooled to avoid serious heat accumulation in the rolled fabrics, which may cause aging, surface discoloration and other problems.

[0023] Furthermore, a trimming device is provided between the cooling mechanism 6 and the second material storage rack 7. During the compounding process, the fabric melts and the edges become uneven, so the edges are trimmed to remove the defective edges.

[0024] Two upper and lower feeding conveyor belts 4 are arranged on one side of the gas composite mechanism 5. They are used for temporary storage of materials. At the same time, the feeding conveyor belts 4 are arranged in upper and lower positions, which can greatly improve the utilization rate of space and reduce the floor space.

[0025] A second unwinding mechanism 3 is provided at one end of the feed conveyor belt 4 located below, and a first storage rack 2 is provided at one end of the feed conveyor belt 4 located above. The first storage rack 2 and the second storage rack 7 have similar structures and are not described herein. The second unwinding mechanism 3 is located below the first storage rack 2, and a first unwinding mechanism 1 is provided at the other end of the first storage rack 2. The first unwinding mechanism 1 and the second unwinding mechanism 3 are used for unwinding fabrics and are common mechanical structures and are not described herein.

[0026] A winding mechanism 8 is provided on the other side of the second material storage rack 7 to wind up the composite fabric. The same winding structure 8 is a common mechanical mechanism and will not be described in detail here.

[0027] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
