Description

Technical Field

[0001] This utility model relates to the field of textile production technology, and in particular to a heating device for a fabric calendering machine. Background Technology

[0002] Fabric calenders are widely used in textile finishing processes. Through the combination of mechanical pressure and temperature, they controllably deform the fibers on the fabric surface, achieving a smooth, even, or uniquely glossy surface finish. The heating device, a key component in the fabric calendering process, provides stable and controllable heat to the calendering rollers or the processing area in contact with the fabric. This ensures appropriate heat distribution during calendering, promoting fiber plastic deformation and surface densification, and improving the texture and visual appeal of the finished fabric.

[0003] Existing fabric calender heating devices typically employ a fixed structure to achieve pressure transmission between the calendering rollers and the fabric. They primarily rely on mechanical supports and rigid connectors to press the calendering rollers firmly against the fabric surface, thus achieving the desired pressure effect. However, in actual production, due to variations in fabric thickness or vibrations and offsets during operation, the pressure exerted by the calendering rollers on the fabric can easily become uneven or fluctuating, leading to inconsistent fabric surface smoothness and calendering effects. Therefore, this paper proposes a heating device for fabric calenders to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-4The present invention provides an embodiment of a heating device for a fabric calender, comprising a calender body 1, wherein a heating component is provided inside the calender body 1 to provide continuous and stable heat energy to the fabric passing through, thereby improving the efficiency and quality of fabric calendering; a pressing mechanism is provided inside the calender body 1 to apply uniform pressure to the fabric, ensuring that the fabric surface is flat and smooth, thereby further enhancing the calendering effect; an adjustment mechanism is provided at the top of the calender body 1 to guide the fabric and change the tension during its transport; and a fabric rack 5 is provided at the front of the calender body 1 to place the fabric to be processed, thereby improving the ease of operation. The pressing mechanism includes a pressing roller 10 and a cavity 6 inside the housing of the calender 1. The pressing roller 10 is used to evenly conduct heat to the surface of the fabric. A slider 7 is provided inside the cavity 6, which can slide vertically to drive the pressing roller 10 to move up and down, thereby achieving dynamic pressing of the fabric. The pressing roller 10 is rotatably connected between the sliders 7, so that it can rotate synchronously during the calendering process, improving the stability and consistency of calendering. A spring 9 is provided inside the cavity 6. One end of the spring 9 is fixedly connected inside the cavity 6, and the other end of the spring 9 is fixedly connected to the bottom of the slider 7. The spring 9 provides continuous elastic support force, so that the pressing roller 10 can maintain constant pressure when facing fabrics of different thicknesses. A limit block 8 is fixedly connected to the side wall of the slider 7. The side wall of the limit block 8 is connected to the inside of the cavity 6 to prevent the slider 7 from detaching from the cavity 6. The heating assembly includes a heating tube 2 and an electric heating rod 3. The heating tube 2 is fixedly connected inside the calender body 1, which can efficiently conduct and evenly distribute the heat generated by the electric heating rod 3. The end of the electric heating rod 3 is embedded inside the calender body 1, and rapid heating is achieved through the internal heating element to ensure a continuous high-temperature environment during the calendering process. The heating rod 3 is located inside the heating tube 2, forming a tightly fitted heat transfer structure, which effectively reduces heat loss and improves energy efficiency. A controller 4 is fixedly connected to the side wall of the calender body 1. The controller 4 can adjust the heating temperature and working status in real time to achieve precise adaptation to the needs of different fabrics. The electric heating rod 3 and the controller 4 are electrically connected to ensure the stable and reliable operation of the heating system. The heating tube 2 is a hollow tube structure, which facilitates the housing of the heating rod part of the electric heating rod 3 and improves the overall heat transfer efficiency. The heating tube 2 is set above the pressing roller 10 so that the heat can be directly applied to the pressing roller 10 and the fabric surface, thereby improving the uniformity of calendering and the smoothness and gloss of the finished product. Reference Figures 1-5The adjustment mechanism includes a rotating shaft 12, a fixing ring 13, and a guide frame 14 to adapt to the thickness and tension requirements of different fabrics, thereby improving processing adaptability and finished product consistency. A top plate 11 is fixedly connected to the top of the calender body 1, providing a solid mounting base for the adjustment mechanism and enhancing its stability. The rotating shaft 12 is rotatably connected between the top plates 11, allowing for flexible adjustment of the position or angle of the guide frame 14. The fixing ring 13 is fixedly connected to the side wall of the rotating shaft 12, providing stable support for the guide frame 14 and allowing it to move with the rotating shaft 12. The guide frame 14 is fixedly connected to the side wall of the fixing ring 13. A connecting plate 18 is fixedly connected to the side wall of the rotating shaft 12, and a hinge frame 19 is fixedly connected to the side wall of the connecting plate 18. A hinge is fixedly connected to the top of the calender body 1. Frame 15 provides a stable fulcrum for the upper adjustment structure. Inside Frame 15, there is a rotating block 16, which is used to realize angle rotation adjustment. A hydraulic rod 17 is fixedly connected to the side wall of the rotating block 16. A rotating block 20 is fixedly connected to the output end of the hydraulic rod 17. The rotating block 20 is rotatably connected inside Frame 29. As an intermediate rotation node, the rotating block 20 can smoothly transition the hydraulic action to Frame 29. The guide frame 14 is set on the upper side of the calender body 1 and is located between the fabric rack 5 and the heating tube 2. It plays an effective guiding role before the fabric enters the heating and calendering area, preventing the fabric from shifting, wrinkling or uneven tension, thereby improving the accuracy of calendering and the surface quality of the fabric.

[0025] Working principle: When using this equipment, the fabric roller is first placed on the fabric rack 5. Then, one side of the fabric is wrapped around the guide frame 14 and passes between the heating tube 2 and the pressing roller 10, and is connected to the external winding mechanism. When the fabric passes between the heating tube 2 and the pressing roller 10, the thickness of the fabric itself will press the pressing roller 10 downward, causing it to move downward and simultaneously compress the spring 9, causing it to deform. The reaction force generated by the spring 9 will support the pressing roller 10, thus making the fabric adhere tightly between the heating tube 2 and the pressing roller 10. At this time, the heating rod 3 is activated by the start controller 4 to heat the inside of the heating tube 2, thereby heating the fabric below. During the fabric calendering process, when it is necessary to adjust the tension of the fabric, the hydraulic rod 17 can be activated to push the rotating block 20 to move, thereby causing the rotating shaft 12 to deflect between the top plates 11, thus changing the offset angle of the guide frame 14, thereby changing the tension of the fabric placed on the guide frame 14, further ensuring the calendering effect.
