[0002] Printed fabric drying equipment is a key piece of equipment in the textile printing and dyeing industry, and its background technology involves multiple fields such as textile processes, heat transfer, and automation control. As the textile printing and dyeing industry develops towards high efficiency, energy saving, and environmental protection, technological innovation in drying equipment has become a core element in improving product quality and production efficiency.

[0003] The current mainstream printing fabric drying equipment adopts a multi-roller conveyor structure. Its core design is as follows: multiple sets of conveyor rollers are arranged in parallel along the fabric's travel direction in a closed drying chamber. After the fabric is introduced through the feed hopper, it is supported and turned alternately by the rollers to form a continuous S-shaped conveying path and finally discharged from the outlet. During this process, the drying heat source circulates and heats the fabric in the chamber to achieve rapid evaporation of moisture. However, during the conveying process, it can cause local tension fluctuations in the fabric, resulting in transverse or longitudinal wrinkles, which leads to low efficiency and poor drying quality.

[0004] Therefore, it is necessary to provide a drying device for printed fabrics to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1-4 A drying device for printed fabrics includes a first mounting plate 1 and a second mounting plate 2. The first mounting plate 1 and the second mounting plate 2 are connected by a plurality of connecting rods 21. A drying chamber 3 is provided between the first mounting plate 1 and the second mounting plate 2. A drying component is provided in the middle of the inner cavity of the drying chamber 3.

[0022] The front and rear ends of the sidewall of the drying chamber 3 are respectively provided with a feed inlet 4 and a discharge outlet 5. The front and rear ends of the inner cavity of the drying chamber 3 are provided with first guide rollers 6 above and below the feed inlet 4 and discharge outlet 5. The rear end of the first guide roller 6 in the inner cavity of the drying chamber 3 is rotatably provided with a waist drum roller 9. The rear end of the first guide roller 6 in the front and upper ends of the inner cavity of the drying chamber 3 is rotatably provided with two outwardly rotating flattening rollers 17 for flattening the fabric on the surface of the waist drum roller 9. The lower part of the inner cavity of the drying chamber 3 is rotatably provided with two sets of opposing second guide rollers 14 and third guide rollers 15.

[0023] In this embodiment, please refer to Figure 4 The waist drum roller 9 is shaped to protrude from both ends toward the middle.

[0024] The waist drum roller 9 adopts a waist drum shape (hyperbolic profile) design, that is, the diameter at both ends of the roller body is smaller than the diameter in the middle, forming an arc-shaped surface with a raised center. When the fabric passes around the waist drum roller 9, the raised part in the middle of the roller body applies an outward radial force to the fabric, causing the fabric to produce a pre-stretching effect in the width direction, which counteracts the internal stress concentration caused by shrinkage during the drying process. The smaller diameter at both ends reduces excessive compression on the edge of the fabric, avoiding edge wrinkling or deformation.

[0025] One end of the printed fabric is slowly fed into the drying chamber 3 through the feed port 4. The fabric first contacts the first guide roller, then moves backward to fit against the waist drum roller 9. After the fit is completed, the two flattening rollers 17 are driven to rotate synchronously. The fabric is subjected to an outward radial force on the raised part in the middle of the roller body, so that the fabric has a pre-stretch effect in the width direction. Then, the two flattening rollers 17 rotate outward to ensure the flatness of the fabric during the drying process. Then, it contacts the second guide roller 14 and the third guide roller 15, and finally contacts the first guide roller 6 at the rear end, and is discharged through the discharge port 5.

[0026] Please refer to Figure 2 The drying assembly includes a heat pump 10 and a hot air hood 13. The heat pump 10 is located in the middle of the top of the drying chamber 3. The air inlet of the heat pump 10 is connected to an external device through a connecting pipe 11. The air outlet of the heat pump 10 is connected to an air outlet pipe 12. The hot air hood 13 is located at the bottom end of the air outlet pipe 12.

[0027] In this embodiment, the hot air hood 13 is designed as an inverted trapezoidal structure, with the upper diameter matching the air outlet duct 12 and the lower width being larger than the fabric width, ensuring that the hot air covers the entire fabric surface.

[0028] When the fabric moisture content drops below 15%, it automatically switches to low wind speed + low temperature mode (temperature decreases by 10-15℃, wind speed decreases by 30%) to reduce energy consumption.

[0029] Please refer to Figure 2 The drying chamber 3 has several first rotating shafts 7 that are rotatably arranged at the front and rear ends of the inner cavity and at the upper and lower ends of the feed inlet 4 and the discharge outlet 5. The first guide roller 6 is fixedly connected to the surface of the first rotating shaft 7.

[0030] Please refer to Figure 1The drying chamber 3 has a plurality of second rotating shafts 8 rotatably arranged inside the cavity and at the rear end of the first guide roller 6. The waist drum roller 9 is fixedly connected to the surface of the second rotating shaft 8. A receiving box 18 is provided on one side of the first mounting plate 1. A first motor is arranged horizontally inside the receiving box 18. The output shaft of the first motor is fixedly connected to the second rotating shaft 8. A third rotating shaft 16 is rotatably arranged at an angle above the waist drum roller 9 inside the drying chamber 3. The flattening roller 17 is fixedly connected to the surface of the third rotating shaft 16. A second motor is arranged at an angle above the first motor inside the receiving box 18. The output shaft of the second motor is fixedly connected to the third rotating shaft 16.

[0031] In this embodiment, the output shaft of the second motor is fixedly connected to the third rotating shaft 16 via a coupling. During the connection process, it is essential to ensure that the concentricity of the shafts at both ends of the coupling meets the requirements to avoid damage to the motor and rotating shaft due to misalignment. Simultaneously, a locking device should be used to securely fix the coupling to prevent loosening during operation.

[0032] When the fabric needs to be dried, after the fabric is in contact with the waist drum roller 9, the second motor is started, which drives the two flattening rollers 17 to rotate, so as to flatten the fabric and ensure that no wrinkles will appear during the drying process, thus avoiding the problem of uneven drying.

[0033] The working principle of the drying equipment for printed fabrics provided by this utility model is as follows:

[0034] The printed fabric is fed into the drying chamber 3 through the inlet 4 at the front end and comes into contact with the upper and lower first guide rollers 6. Under their guidance, it moves smoothly into the drying chamber 3. The fabric fits into the waist drum roller 9, which has a waist drum-shaped design. The central protrusion pre-stretches the fabric in the width direction to offset the internal stress of drying shrinkage. The small diameter at both ends reduces the pressure on the fabric edges and prevents wrinkling and deformation. The second motor is started, which drives the two inclined flattening rollers 17 to rotate outward synchronously to further flatten the fabric on the surface of the waist drum roller 9 and prevent wrinkles and unevenness in subsequent drying. After being flattened, the fabric comes into contact with the two sets of opposing second and third guide rollers below, changing its running path and receiving support and guidance to maintain stable operation. The surface of the fabric is dried by the drying components. The dried fabric is guided by the rear first guide roller 6 and discharged from the rear outlet 5 of the drying chamber 3, resulting in a dry and flat printed fabric.

[0035] Compared with related technologies, the drying equipment for printed fabrics provided by this utility model has the following beneficial effects:

[0036] The printed fabric is fed into the drying chamber 3 through the inlet 4 at the front end and comes into contact with the upper and lower first guide rollers 6. Under their guidance, the fabric moves smoothly into the drying chamber 3 and adheres to the waist drum roller 9. After adhering, the fabric is further flattened on the surface of the waist drum roller 9 by two flattening rollers 17 rotating outwards in sync, preventing wrinkles and unevenness during subsequent drying. After being flattened, the fabric comes into contact with the two sets of opposing second and third guide rollers below, maintaining stable operation. The surface of the fabric is then dried by the drying components. After drying, the fabric is guided by the rear first guide roller 6 and discharged from the rear outlet 5 of the drying chamber 3, resulting in a dry and flat printed fabric. This ensures that the fabric will not have wrinkles or deformation during the drying process, greatly improving drying efficiency and drying quality.
