Description

Technical Field

[0001] This utility model relates to the field of fabric hot pressing technology, and in particular to a double-roller synchronous calendering device for processing polyester fabrics. Background Technology

[0002] In the production and processing of polyester fabrics, the hot pressing (calendering) process is a crucial step that determines the surface texture and core performance of the fabric, and its processing precision is directly related to the product's market competitiveness. Polyester fabrics that have undergone standardized hot pressing treatment not only have a uniform surface luster, excellent smoothness, and a delicate and smooth feel, but also significantly enhanced wrinkle resistance and abrasion resistance. This allows them to meet the differentiated quality requirements of various fields such as apparel, home textiles, industrial filter materials, and outdoor protection, becoming one of the core processes for increasing product added value.

[0003] While the dual-roller synchronous calendering equipment widely used in the industry can achieve basic hot pressing functions, it reveals significant deficiencies in adaptability and precision in actual production. On the one hand, the existing equipment has a relatively fixed structural design, lacking a flexible switching mechanism for hot pressing paths and processing cycles, making it difficult to adapt to the process requirements of different products. For high-end fabrics requiring multiple layers of hot pressing, multiple machines must be connected in series or the fabric must be repeatedly fed, resulting in a cumbersome process and potential fabric stretching and deformation. Conversely, for ordinary fabrics requiring single hot pressing, the equipment's capacity cannot be fully utilized, leading to low production efficiency. On the other hand, the hot pressing pressure of existing equipment is mostly a factory-preset constant value, lacking a targeted dynamic adjustment system. Due to significant differences in polyester fabric thickness (e.g., 10-50g / ㎡ for lightweight, 50-200g / ㎡ for regular, and 200-500g / ㎡ for heavyweight), constant pressure can easily lead to excessive stretching and luster distortion in thin fabrics, while thick fabrics may experience insufficient calendering and uneven surfaces, making it difficult to ensure consistent calendering quality for fabrics of different specifications. In addition, the insufficient precision in adjusting the spacing of the hot press rollers in some devices further exacerbates the instability of the calendering effect, hindering the development of polyester fabrics towards high-end and diversified directions. Utility Model Content

[0004] To solve the above problems, this utility model provides a double-roller synchronous calendering device for processing polyester fabrics.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a double-roller synchronous calendering device for processing polyester fabric, comprising: a device base, an installation frame fixedly connected to the top of the device base, and a first rectangular frame provided on the inner side of the installation frame. A lifting drive assembly is mounted on the top of the mounting frame. The power output end of the lifting drive assembly is connected to the first rectangular frame for driving the first rectangular frame to move linearly in the vertical direction. The positioning support frame is symmetrically fixed to one side of the outer wall of the mounting frame. A second rectangular frame is fixedly installed between the two positioning support frames, and the second rectangular frame and the first rectangular frame are horizontally corresponding to each other in the initial state. An adjustable dual-roller hot pressing assembly is correspondingly embedded in the inner side of the second rectangular frame and the inner side of the first rectangular frame. The adjustable dual-roller hot pressing assembly is used to perform synchronous hot pressing and calendering treatment on polyester fabric.

[0006] By adopting the above technical solution, when the first rectangular frame and the second rectangular frame are distributed left and right, the polyester fabric can be hot-pressed twice to improve the hot-pressing effect; if only a single hot-pressing is required, the first rectangular frame and its connecting parts can be lifted, and the device can simultaneously perform a single hot-pressing on the two pieces of polyester fabric.

[0007] Furthermore, the lifting drive assembly includes a lifting telescopic rod, which is fixedly installed on the top of the mounting frame, and a linkage support plate is fixedly connected to the power end of the lifting telescopic rod.

[0008] By adopting the above technical solution, the displacement of the linkage support plate can be driven synchronously when the telescopic rod is being raised.

[0009] Furthermore, lifting connecting rods are fixedly installed at the bottom of both ends of the linkage support plate, and the top of the mounting frame is provided with a clearance through hole adapted to the lifting connecting rod.

[0010] By adopting the above technical solution, the lifting connecting rod can be displaced along with the displacement of the linkage support plate.

[0011] Furthermore, the end of the lifting connecting rod away from the linkage support plate passes through the clearance through hole and is fixedly connected to the top of the first rectangular frame.

[0012] By adopting the above technical solution, the lifting connecting rod is inserted into the mounting frame through the clearance hole and one end is connected to the first rectangular frame. Therefore, the lifting connecting rod can drive the first rectangular frame to move.

[0013] Furthermore, reinforcing rods are fixedly connected to both sides of the second rectangular frame, and one end of each reinforcing rod is fixed to the positioning support frame.

[0014] By adopting the above technical solution, the stability of the second rectangular frame during installation is increased by using a heating rod.

[0015] Furthermore, the adjustable double-roller hot pressing assembly includes mounting bases symmetrically fixed to the inner sides of the first rectangular frame and the second rectangular frame, and each mounting base is fixed with a bidirectional adjustable telescopic rod.

[0016] By adopting the above technical solution, the bidirectional adjustable telescopic rod can be fixed by installing a base.

[0017] Furthermore, both ends of the bidirectional adjustable telescopic rod are fixedly connected to connecting mounting plates, and a hot press roller frame is fixedly connected between the two connecting mounting plates corresponding to different bidirectional adjustable telescopic rods. A drive motor is installed on the outer wall of the hot press roller frame by bolts.

[0018] By adopting the above technical solution, the position of the connecting mounting plate and the hot press roller frame can be changed by adjusting the telescopic rod in both directions.

[0019] Furthermore, the output shaft of the drive motor is connected to a heated calendering roller, and a guide limiting rod is fixed in a linear array on one side of the hot calendering roller frame. The end of the guide limiting rod away from the hot calendering roller frame passes through the first rectangular frame and the second rectangular frame respectively.

[0020] By adopting the above technical solution, the stability of the hot press roller frame during displacement is increased under the action of the guide limit rod.

[0021] In summary, this utility model has the following beneficial effects: This device, through the coordinated operation of the adjustable double-roller hot pressing assembly and the lifting drive assembly, achieves flexible switching of processing modes and precisely adapts to the calendering requirements of fabrics of different thicknesses. Specifically: when the first rectangular frame and the second rectangular frame are horizontally distributed, the adjustable double-roller hot pressing assembly within the two frames can perform two hot pressings on the same piece of polyester fabric sequentially, significantly improving the fabric's gloss and smoothness; if only a single hot pressing is required, after lifting the first rectangular frame and its connecting parts through the lifting drive assembly, the adjustable double-roller hot pressing assembly within the two frames can simultaneously process two pieces of polyester fabric, effectively improving production efficiency. Furthermore, the adjustable double-roller hot pressing assembly can specifically adjust the hot pressing parameters according to the thickness differences of the polyester fabric, avoiding the problems of stretching and deformation of thin fabrics and insufficient calendering of thick fabrics under constant pressure, ensuring consistent hot pressing quality for polyester fabrics of different specifications.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figures 1-5 As shown in the embodiment of this application, a dual-roller synchronous calendering device for processing polyester fabric is disclosed, including a device base 1, a mounting frame 2 fixedly connected to the top of the device base 1, and a first rectangular frame 3 disposed on the inner side of the mounting frame 2; a lifting drive component 4, assembled on the top of the mounting frame 2, the power output end of the lifting drive component 4 being connected to the first rectangular frame 3 for driving the first rectangular frame 3 to move linearly in the vertical direction; positioning support frames 5, symmetrically fixedly connected to one side of the outer wall of the mounting frame 2, and a second rectangular frame 6 fixedly installed between the two positioning support frames 5, and the second rectangular frame 6 and the first rectangular frame 3 being horizontally correspondingly distributed in the initial state; and an adjustable dual-roller hot pressing component 7, correspondingly embedded in the inner side of the second rectangular frame 6 and the inner side of the first rectangular frame 3, the adjustable dual-roller hot pressing component 7 being used to perform synchronous hot pressing and calendering treatment on polyester fabric.

[0026] When using this dual-roller synchronous calendering device for polyester fabric processing, the processing mode can be flexibly switched according to the process requirements of the polyester fabric. Maintaining the initial horizontal alignment of the first rectangular frame 3 and the second rectangular frame 6, the polyester fabric is fed into the device. The fabric sequentially passes through the adjustable dual-roller hot-pressing assembly 7 inside the second rectangular frame 6 and the adjustable dual-roller hot-pressing assembly 7 inside the first rectangular frame 3. The two adjustable dual-roller hot-pressing assemblies 7 perform hot-pressing and calendering treatment on the same piece of fabric in succession, which can significantly improve the gloss and smoothness of the fabric surface, meeting the processing requirements of high-quality polyester fabrics. If only the processing mode needs to be adjusted... When the polyester fabric undergoes a single hot pressing, the lifting drive assembly 4, mounted on the top of the mounting frame 2, is activated. The power output end of the lifting drive assembly 4 drives the first rectangular frame 3 to move linearly in the vertical direction, adjusting it to a position staggered vertically from the second rectangular frame 6. At this time, two pieces of polyester fabric can be simultaneously fed into two adjustable double-roller hot pressing assemblies 7 for synchronous hot pressing and calendering, effectively increasing the processing volume per unit time. In both processing modes, the adjustable double-roller hot pressing assembly 7 can adjust the hot pressing parameters according to the thickness difference of the polyester fabric, avoiding problems such as insufficient calendering of thick fabrics due to constant pressure.

[0027] The lifting drive assembly 4 includes a lifting telescopic rod 401, which is fixedly installed on the top of the mounting frame 2. The power end of the lifting telescopic rod 401 is fixedly connected to a linkage support plate 402. Lifting connecting rods 403 are fixedly installed at the bottom of both ends of the linkage support plate 402. The top of the mounting frame 2 is provided with a clearance through hole adapted to the lifting connecting rod 403. The end of the lifting connecting rod 403 away from the linkage support plate 402 passes through the clearance through hole and is fixedly connected to the top of the first rectangular frame 3.

[0028] When switching processing modes, the lifting telescopic rod 401 is activated. The power end of the lifting telescopic rod 401 drives the linkage support plate 402 to rise and fall synchronously. The lifting connecting rods 403 at the bottom of both ends of the linkage support plate 402 then move vertically along the clearance through hole at the top of the mounting frame 2, thereby driving the first rectangular frame 3 to achieve stable rise and fall. This adjusts the relative position of the first rectangular frame 3 and the second rectangular frame 6, quickly completing the mode switch between double hot pressing and single hot pressing of double fabrics. The entire lifting process is stable in transmission and precise in adjustment, effectively ensuring the operational reliability of the device when switching processing modes.

[0029] The second rectangular frame 6 has reinforcing rods 8 fixedly connected to both sides. One end of the reinforcing rod 8 is fixed to the positioning support frame 5. The reinforcing rod 8 effectively disperses the vibration and pressure generated by the adjustable double roller hot press assembly 7 during operation, thus improving stability.

[0030] The adjustable double-roller hot press assembly 7 includes mounting bases 701 symmetrically fixed inside the first rectangular frame 3 and the second rectangular frame 6. Each mounting base 701 has a bidirectional adjustable telescopic rod 702 fixed inside. Both ends of the bidirectional adjustable telescopic rod 702 are fixedly connected to connecting mounting plates 703. A hot press roller frame 704 is fixedly connected between the two connecting mounting plates 703 corresponding to different bidirectional adjustable telescopic rods 702. A drive motor 705 is bolted to the outer wall of the hot press roller frame 704. The output shaft of the drive motor 705 is connected to a heating and calendering roller 706. A guide limiting rod 707 is fixed in a linear array on one side of the hot press roller frame 704. The end of the guide limiting rod 707 away from the hot press roller frame 704 moves through the first rectangular frame 3 and the second rectangular frame 6 respectively.

[0031] During operation, the bidirectional adjustable telescopic rods 702 within the mounting base 701 extend and retract according to the thickness requirements of the polyester fabric. Synchronous movement of the two bidirectional adjustable telescopic rods 702 is achieved using existing technology. Specifically, this can be achieved by connecting them to the same programmable logic controller (PLC), which outputs a synchronous control signal to drive the two bidirectional adjustable telescopic rods 702 to maintain the same extension and retraction rate and displacement stroke. This causes the connecting mounting plates 703 at both ends to move synchronously, thereby smoothly moving the hot press roller frame 704 between the corresponding connecting mounting plates 703 of the different bidirectional adjustable telescopic rods 702. The guide limit rods 707 of the linear array on one side slide along the inner side of the first rectangular frame 3 and the second rectangular frame 6, providing precise guidance and limiting for the hot press roller frame 704, and preventing tilting or jamming during the displacement of the hot press roller frame 704. Then, the drive motor 705 starts and drives the heating calendering roller 706 to rotate. The heating calendering roller 706 applies a uniform hot pressing force to the conveyed polyester fabric. The entire adjustment process is flexible, precise and stable, and can be adapted to polyester fabrics of different thicknesses. It effectively avoids the problems of thin fabric stretching and deformation and thick fabric insufficient calendering, and ensures the consistency of hot pressing quality of various polyester fabrics.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
