Description

Technical Field

[0001] This utility model belongs to the field of sofa leather fabric processing technology, specifically relating to a winding device for sofa leather production. Background Technology

[0002] Sofa leather is the main raw material used to make genuine leather sofas. There are many types of raw materials for sofa leather, including genuine leather, PU leather, PVC shoe upper leather, etc.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN222160726U discloses "a pretreatment and finishing device for composite fabrics", which includes a workbench, an upper scraper fixedly installed on the outer surface of the mounting plate, a lower scraper fixedly installed on the opposite outer surface of the first gantry frame, a plurality of dense through holes on the outer surface of the upper scraper and the lower scraper, two brush cylinders rotatably connected to the opposite outer surface of the two first vertical plates, a motor fixedly installed on the outer surface of the right first vertical plate, and gears fixedly connected to the outer surface of the two brush cylinders.

[0004] While existing composite fabric pretreatment equipment can iron the fabric surface by setting up a first flattening roller, a second flattening roller, and a heating wire, along with a second rotating wheel and a second threaded rod, thus improving the fabric's smoothness, preventing wrinkles, and enhancing the quality of subsequent processing, in actual operation, the composite fabric needs to be rolled up promptly after ironing to facilitate subsequent processing steps. It is worth noting that the ironing temperature is typically controlled between 120℃ and 150℃ (based on infrared thermometry data). If the ironed composite fabric is rolled up directly without cooling, the internal heat cannot dissipate quickly, and the fabric temperature remains between 80℃ and 100℃ (measured by a thermal imager). This not only affects the fabric's shaping effect but also reduces its overall quality. To address these issues, this application proposes a winding device for sofa leather production.

[0027] Example

[0028] Please see Figures 1-5 The present invention provides the following technical solution: a winding device for sofa leather production, including a support frame 1, on which a flattening roller 2, a brush roller 3 and a winding roller 4 are arranged in sequence along the fabric traveling direction;

[0029] Two mounting brackets 5 are respectively located on the upper and lower sides of the support frame 1. Each mounting bracket 5 is equipped with a cooling component with an adjustable tilt angle and an adjustment component for adjusting the angle of the cooling component.

[0030] The cooling component includes a flip plate 107 rotatably connected to the mounting bracket 5 via a rotating shaft, and an air outlet component provided on the flip plate 107. The adjustment component also includes a clearance hole 101 opened on the mounting bracket 5. Mounting seats 102 with bearings are provided on both sides of the clearance hole 101. A rotating seat 103 is mounted between the two mounting seats 102 via bearings. A lead screw 104 is provided on the rotating seat 103 via threads. One end of the lead screw 104 is rotatably connected to a connecting rod 105.

[0031] The flip plate 107 is provided with a fixed seat 106, and the fixed seat 106 is connected to the connecting rod 105 through a rotating shaft. A pair of first connecting seats 108 are also provided on one side of the flip plate 107, and a pair of second connecting seats 109 are provided on one side of the mounting frame 5. The pair of second connecting seats 109 are connected to the pair of first connecting seats 108 through a rotating shaft. A heating wire can be set inside the flattening roller 2. The heating wire is started by an external power supply. In use, the sofa leather fabric is passed between the pair of flattening rollers 2 and the pair of brush rollers 3 and wound around the take-up roller 4. The take-up roller 4 is started, and then the heating wire is started to iron the fabric. After the sofa leather fabric is ironed, it continues to move forward. When the sofa leather fabric passes between the pair of brush rollers 3, the impurities and burrs on the surface of the sofa leather fabric are cleaned by the rotation of the brush rollers 3, which further improves the flatness of the fabric.

[0032] When the take-up roller 4 takes up the sofa leather fabric again, the air outlet component is activated to cool the sofa leather fabric. By manually turning the hand crank 110, the lead screw 104 rotates in the rotating seat 103 on the mounting base 102. While rotating, the lead screw 104 moves along the thread direction. As the lead screw 104 moves, it drives the flip plate 107 to flip around the axis between the first connecting seat 108 and the second connecting seat 109 through the connecting rod 105. This adjusts the tilt angle of the air outlet component on the flip plate 107, so that the cold air blown out by the air outlet component can fit the fabric more closely, improve the cooling efficiency, and ensure that the fabric can be fully cooled before taking up, resulting in better shaping effect and higher overall quality. This allows the heat inside the fabric to dissipate quickly during taking up, avoiding the problem of poor fabric shaping effect or overall quality decline caused by high temperature.

[0033] Preferably, by Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, the air outlet assembly includes an air distribution pipe 6 and multiple exhaust pipes 7 distributed along the air distribution pipe 6. Each exhaust pipe 7 is provided with several jet pipes 8 facing the fabric surface. A flexible hose can be connected to the air distribution pipe 6, and cold air can be delivered into the air distribution pipe 6 through an external air pump. The cold air is sprayed out through the exhaust pipes 7 and jet pipes 8 in sequence to cool the fabric, thereby improving the cooling efficiency of the fabric. At the same time, the arrangement of multiple exhaust pipes 7 and jet pipes 8 allows the cold air to cover the fabric surface more evenly, further improving the cooling effect.

[0034] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the mounting bracket 5 has a guide hole 10, and the flip plate 107 is provided with a mounting rod 9 that passes through the guide hole 10. The mounting rod 9 limits the flip plate 107, so that the flip plate 107 can move along the trajectory of the guide hole 10 during the flipping process, avoiding the flip plate 107 from shifting or shaking during the flipping process, and improving the stability and reliability of the cooling component.

[0035] Preferably, by Figure 3 As shown, in this embodiment, the width of the clearance hole 101 is greater than the diameter of the lead screw 104; this ensures that the lead screw 104 will not interfere with or get stuck in the clearance hole 101 during rotation, thus ensuring the smooth operation of the adjustment component and allowing the user to easily adjust the tilt angle of the flip plate 107 to adapt to different fabrics and processing requirements.

[0036] Preferably, by Figure 5 As shown, in this embodiment, the diameter of the mounting rod 9 is the same as the width of the guide hole 10, and the mounting rod 9 is made of metal. The metal mounting rod 9 has high strength and stability, which can ensure the smooth operation of the flip plate 107 during the flipping process. At the same time, the diameter of the mounting rod 9 is the same as the width of the guide hole 10, which can ensure that the mounting rod 9 moves smoothly in the guide hole 10, further improving the stability and reliability of the cooling component.

[0037] Preferably, by Figure 3 As shown, in this embodiment, one end of the lead screw 104 is provided with a hand crank 110, and the outer wall of the hand crank 110 is provided with anti-slip texture. The user can easily adjust the rotation of the lead screw 104 by rotating the hand crank 110. The anti-slip texture design increases the friction of the surface of the hand crank 110, ensuring stable grip and rotation even when the hands are sweaty during operation. This makes it easier for the user to accurately control the tilt angle of the flip plate 107, improving the convenience and accuracy of operation.

[0038] Components not described in detail in this article are existing technologies.

[0039] The working principle and usage process of this utility model are as follows: a heating wire can be installed inside the flattening roller 2, and the heating wire can be started by an external power supply.

[0040] The hose is attached to the air distribution pipe 6, and cold air is delivered into the air distribution pipe 6 through an external air pump. The cold air is then sprayed out through the exhaust pipe 7 and the jet pipe 8 to cool the fabric.

[0041] In use, the sofa leather fabric is passed between a pair of flattening rollers 2 and a pair of brush rollers 3 and wound onto the take-up roller 4. The take-up roller 4 is started, and then the heating wire is started to iron the fabric. After the sofa leather fabric is ironed, it continues to move forward. When the sofa leather fabric passes between a pair of brush rollers 3, the rotation of the brush rollers 3 cleans the impurities and burrs on the surface of the sofa leather fabric, further improving the smoothness of the fabric.

[0042] When the take-up roller 4 takes up the sofa leather fabric again, the air outlet component is activated to cool the sofa leather fabric. By manually turning the hand crank 110, the lead screw 104 rotates in the rotating seat 103 on the mounting base 102. While rotating, the lead screw 104 moves along the thread direction. As the lead screw 104 moves, it drives the flip plate 107 to flip around the axis between the first connecting seat 108 and the second connecting seat 109 through the connecting rod 105. This adjusts the tilt angle of the air outlet component on the flip plate 107, so that the cold air blown out by the air outlet component can fit the fabric more closely, improve the cooling efficiency, and ensure that the fabric can be fully cooled before taking up, resulting in better shaping effect and higher overall quality. This allows the heat inside the fabric to dissipate quickly during taking up, avoiding the problem of poor fabric shaping effect or overall quality decline caused by high temperature.

[0043] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
