Description

Technical Field

[0001] This utility model is a dyeing and drying device for fiber fabrics, belonging to the field of fiber fabric processing technology. Background Technology

[0002] After dyeing, fiber fabrics (such as cotton, polyester, wool, etc.) need to be dried to remove moisture (the moisture content needs to be reduced from 40%-60% after dyeing to 5%-8%) to ensure the stability of subsequent shaping, cutting and other processes. The quality of drying directly affects the performance of the fabric: over-drying will cause fiber embrittlement (e.g., wool breaking strength decreases by 15%); uneven drying will cause color difference (color difference value ΔE > 2 for the same batch of fabric); high temperature damage will damage the fabric's feel (e.g., polyester fabric becomes stiff, and bending stiffness increases by 20%).

[0003] Chinese patent CN219824612U discloses a fiber fabric dyeing and drying device. This device includes a conveyor belt motor, adsorption holes, a second drive cylinder, a second fixed column, an adsorption roller, a third fixed column, and a corrugated pipe. This design can absorb moisture from the surface of the fiber fabric before drying, making the hot air drying of the fiber fabric highly efficient and eliminating the need for long drying times, thus preventing damage to the internal structure of the fiber fabric from prolonged drying. However, this fiber fabric dyeing and drying device directly applies high-temperature drying to fiber fabrics at room temperature, which can easily damage the fabric's properties. There is an urgent need for a fiber fabric dyeing and drying device to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a fiber fabric dyeing and drying device to solve the problems mentioned in the background. This invention employs a multi-stage gradient drying unit, which can perform pre-drying, main drying, and auxiliary drying on fiber fabrics. This gradient removal of moisture from the fiber fabrics avoids high-temperature damage to sensitive fibers and ensures the uniformity of drying. Subsequent cooling effectively prevents subsequent shrinkage caused by residual heat in the fiber fabrics, thus ensuring the drying quality of the fiber fabrics.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiber fabric dyeing and drying device, comprising a drying chamber, a pre-drying chamber, a main drying chamber, and an auxiliary drying chamber. The drying chamber has a fabric inlet at its left end and a cooling chamber at its right end. Fabric to be dried is wrapped between the drying chamber and the cooling chamber.

A honeycomb perforated plate is horizontally embedded below the cooling box.

[0008] Furthermore, the first connecting pipe is connected to the first pipe body, and the second pipe body is connected to the second connecting pipe, with both the first pipe body and the second pipe body positioned above the fabric to be dried.

[0009] Furthermore, a first dustproof net is installed on the upper end of the fan, and a second dustproof net is installed on the upper end of the second fan.

[0010] Furthermore, a PLC control panel is installed on the left end of the drying chamber.

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1-4This utility model provides a technical solution: a fiber fabric dyeing and drying device, including a drying chamber 1, a pre-drying chamber 5, a main drying chamber 8, and an auxiliary drying chamber 12. A fabric inlet 3 is provided at the left end of the drying chamber 1, and a cooling chamber 20 is installed at the right end of the drying chamber 1. Fabric 4 to be dried is wrapped between the drying chamber 1 and the cooling chamber 20. The interior of the drying chamber 1 is divided from left to right by multiple partitions into the pre-drying chamber 5, the main drying chamber 8, and the auxiliary drying chamber 12. A first pipe 6 is installed through the upper end of the pre-drying chamber 5, and a second pipe 11 is installed through the upper end of the auxiliary drying chamber 12. A return air limiting frame 9 is fixed at the lower end of the main drying chamber 8, and a first connecting pipe is installed through the rear end of the return air limiting frame 9. 7 and the second connecting pipe 10, the first fan 14 is located at the upper end of the main drying chamber 8, the lower end of the first fan 14 is provided with a disc heating pipe 15 and a uniform air flow plate 16, the connection between the pre-drying chamber 5 and the main drying chamber 8 is provided with a first guide roller group 17, the main drying chamber 8 is provided with an auxiliary roller 18, the connection between the main drying chamber 8 and the auxiliary drying chamber 12 is provided with a second guide roller group 19, the pre-drying chamber 5, the main drying chamber 8 and the auxiliary drying chamber 12 are all equipped with an infrared humidity sensor 24 and a platinum resistance temperature sensor 25, and the upper end of the cooling box 20 is equipped with a second fan 22. This design solves the problem that the original fiber fabric dyeing and drying device directly dries the fiber fabric at room temperature at high temperature, which easily damages the fabric performance.

[0017] As the first embodiment of this utility model: a door 2 is installed at the front end of the drying chamber 1 via a hinge. The added door 2 facilitates the opening of the drying chamber 1, thereby making it convenient to wind the fabric 4 to be dried. The left end of the fabric 4 to be dried is connected to the external feeding equipment via the fabric inlet 3. The right end of the cooling chamber 20 has a fabric outlet, and the right end of the fabric 4 to be dried passes through the fabric outlet and is connected to the external winding equipment. A honeycomb perforated plate 23 is horizontally embedded below the cooling chamber 20. The added external feeding and winding equipment are existing known take-up and take-up rollers and their equipped units, and their working principles will not be described in detail. The first connecting pipe 7 is connected to the first pipe body 6, and the second pipe body 11 is connected to the second connecting pipe 10. Both the first pipe body 6 and the second pipe body 11 are located above the fabric 4 to be dried. The connection between the first connecting pipe 7 and the first pipe body 6, and the connection between the second pipe body 11 and the second connecting pipe 10, facilitates the flow of hot air from the main drying chamber 8 into the pre-drying chamber 5 and the auxiliary drying chamber 12, achieving a recycling effect. A first dustproof net 13 is installed on the upper end of the fan 14, and a second dustproof net 21 is installed on the upper end of the second fan 22. The addition of the first dustproof net 13 and the second dustproof net 21 can prevent the fan 14 and the second fan 22 from sucking in large dust and impurities.

[0018] A PLC control panel 26 is installed on the left end of the drying chamber 1. The PLC control panel 26 is connected to the first fan 14, the disc heating tube 15, the second fan 22, multiple infrared humidity sensors 24, and multiple platinum resistance temperature sensors 25 via wires. The added PLC control panel 26, the first fan 14, the disc heating tube 15, the second fan 22, the multiple infrared humidity sensors 24, and the multiple platinum resistance temperature sensors 25 are all existing and well-known mature equipment, and their control principles will not be elaborated. The fabric 4 to be dried is wound from left to right between the first guide roller group 17, the auxiliary roller 18, and the second guide roller group 19. The addition of the first guide roller group 17, the auxiliary roller 18, and the second guide roller group 19 facilitates the auxiliary conduction of the fabric 4 to be dried.

[0019] As a second embodiment of this utility model: In actual use, the parameters of multiple platinum resistance temperature sensors 25 are set through the PLC control panel 26 to detect the temperature in the pre-drying chamber 5, the main drying chamber 8, and the auxiliary drying chamber 12 in real time. This controls the activation of the first fan 14 and the disc heating tube 15. The first fan 14 draws in outside air through the first dust filter 13 and exchanges heat with the disc heating tube 15, causing hot air to move downwards. This hot air passes through the air distribution plate 16 and blows downwards, then passes through the return air limiting frame 9 and is conducted to the first connecting pipe 7 and the second connecting pipe 10. This allows the pre-drying chamber 5 to enter circulating hot air through the first pipe 6 (the hot air temperature in the pre-drying chamber 5 is lower than that in the main drying chamber 8). The auxiliary drying chamber 12 also enters hot air through the second pipe 11 (the hot air temperature in the auxiliary drying chamber 12 is lower than that in the main drying chamber 8). (Low temperature) During this process, the fabric 4 to be dried is initially preheated by the first tube 6, while the fabric 4 to be dried entering the main drying chamber 8 is dried again by the heated hot air. Then, the fabric 4 to be dried entering the auxiliary drying chamber 12 is dried thoroughly by the remaining hot air. During this process, multiple infrared humidity sensors 24 and multiple platinum resistance temperature sensors 25 monitor the temperature in the pre-drying chamber 5, the main drying chamber 8, and the auxiliary drying chamber 12 in real time. When the detected temperature exceeds the temperature that the fabric 4 to be dried can withstand, the PLC control panel 26 controls the first fan 14 and the disc heating tube 15 to be de-energized. Finally, the fabric 4 to be dried thoroughly enters the cooling box 20, and the second fan 22 is started. The second fan 22 can draw in ambient air at room temperature through the second dust filter 21 and blow it onto the fabric 4 to be dried, thereby achieving the cooling of the dried fabric 4 (30s). The internal temperature is lowered to below 30℃, with a shrinkage rate of ≤0.5%, ensuring dimensional stability. This effectively avoids subsequent shrinkage caused by residual heat in the fiber fabric and ensures the drying quality of the fiber fabric.
