Description

Technical Field

[0001] This utility model belongs to the technical field of printing and dyeing equipment, specifically relating to a green printing and dyeing equipment for soybean fiber fabric. Background Technology

[0002] The green dyeing and printing equipment for soybean fiber fabric is a device specifically designed for dyeing and printing soybean fiber fabric to achieve environmentally friendly dyeing. This equipment utilizes a novel dye liquor formula, employing non-toxic, harmless, and biodegradable dyes and auxiliaries to reduce chemical pollution during the dyeing and printing process.

[0003] Application No. 202022784367.0 discloses a method for printing and dyeing polyester coated fabric. "After each printing and dyeing process using the printing rollers, the polyester coated fabric immediately enters a heating chamber. A temperature-controlled heating rod heats the air above the fabric, causing the fan to blow hot air. The combined action of the heating rod and the fan accelerates the drying rate of the ink on the surface of the polyester coated fabric, improving the printing and dyeing quality." However, uneven coating adhesion on the printing roller surface is a critical and common problem in the printing and dyeing process. The main causes include fluctuations in paint viscosity, poor roller surface condition, unstable paint supply, and fluctuations in roller speed. Changes in paint viscosity can lead to uneven flow on the roller surface, while wear, dirt, or aging on the roller surface further affects paint adhesion. An inability to provide a continuous and stable paint flow rate also results in uneven paint distribution on the roller surface. Furthermore, unstable roller speed directly affects the residence time and amount of paint on the roller surface, exacerbating uneven adhesion. This uneven adhesion can directly lead to problems such as obvious color differences, spots, and inconsistent coating thickness on the fabric. Utility Model Content

[0004] The purpose of this invention is to provide a green printing and dyeing device for soybean fiber fabrics, so as to solve the problems mentioned in the background art, such as uneven coating adhesion on the surface of the printing and dyeing roller, which can lead to color difference, spots and uneven coating on the fabric.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a green dyeing device for soybean fiber fabric, comprising: an operating table, with an input device and an output device respectively arranged on both sides of the operating table; a through fabric body is provided inside the input device and the output device; a first dyeing roller is provided at the bottom end of the fabric body; a second dyeing roller is provided at the top end of the fabric body; a scraper and a brush are provided on the sides of both the first and second dyeing rollers; an electric telescopic rod is connected to the side wall of both the scraper and the brush; a cleaning box is installed on the end face of the operating table; an opening is provided on the side wall of the cleaning box; the electric telescopic rod can drive the scraper and the brush to enter and exit the cleaning box through the opening; a baffle assembly is installed inside the opening; and a rinsing assembly and a return assembly are configured inside the cleaning box.

[0006] Preferably, the partition assembly includes a baffle and multiple springs. The baffle is movably connected to the opening. A hollow tube is installed on the outer wall of the baffle. A fixed tube is installed on the inner wall of the opening, and the hollow tube is nested outside the fixed tube. Horizontal plates are connected to both the inner and outer walls of the cleaning tank. Vertical plates are connected to the side walls of both the inner and outer horizontal plates. Multiple springs are evenly distributed between the baffle and the vertical plates.

[0007] The rinsing assembly includes an inlet pipe and a rinsing head. The inlet pipe is connected to the side wall of the cleaning tank, and the rinsing head is installed at the outlet end of the inlet pipe.

[0008] The reflux assembly includes a reflux pipe, a filter collection box, and a liquid pump. The reflux pipe is connected to the bottom of the side wall of the cleaning tank. The filter collection box is installed at the liquid outlet of the reflux pipe. The liquid pump is installed at the liquid outlet of the filter collection box, and the liquid outlet of the liquid pump is connected to the liquid inlet pipe.

[0009] Through the above technical solution:

[0010] In operation, the control panel serves as the core platform of the entire dyeing and printing equipment, providing stable support for other components. Input and output devices are symmetrically arranged on both sides of the control panel, forming a complete feeding and discharging channel. The fabric enters through the input device, flows through the entire dyeing and printing process, and is finally output through the output device, ensuring the continuity and efficiency of the dyeing and printing process.

[0011] Before being processed by the dyeing rollers, the soybean fiber fabric itself needs to undergo several meticulous pretreatment processes to ensure the optimal state of the fabric for dyeing:

[0012] Desizing treatment: First, remove the sizing agent applied to the fabric during the weaving process. Use hot water or enzyme desizing method to ensure that the chemical reagents can fully contact the fibers during subsequent treatment.

[0013] Scouring treatment: Using alkaline solutions to remove impurities such as grease and pectin from the fiber surface, improving the fabric's water absorption and making it easier for dyes to adhere.

[0014] Bleaching treatment: For products that require whiteness, bleaching agents such as hydrogen peroxide are used to remove pigments and improve the whiteness of the fabric.

[0015] Tensioning: Adjusting the width and shape of the fabric through stretching and other methods to ensure the smoothness of the fabric during printing and dyeing.

[0016] After dyeing, a color-fixing treatment is required to ensure the dye adheres more firmly to the fibers. This can be achieved by using a cationic color-fixing agent to react with the anionic groups in the dye. Following this, the fabric is washed to remove any unfixed dye and auxiliaries from the surface, ensuring colorfastness and fabric cleanliness. Finally, to improve the fabric's feel and appearance, a softening finish and stretching are performed, giving the fabric a soft and comfortable touch, stabilizing its dimensions, and improving its smoothness.

[0017] During the dyeing process, the coordinated operation of the first and second dyeing rollers ensures that the dye is evenly applied to the fabric. The rotation speed and tension of the dyeing rollers can be adjusted according to the characteristics of different fabrics and dyes to achieve the best dyeing effect.

[0018] During the printing and dyeing process, the electric telescopic rod is activated, which drives the scraper and brush to move closer to the first and second printing and dyeing rollers.

[0019] With its rigid structure, the scraper effectively removes excess paint from the surface of the printing roller by precisely adjusting the contact pressure and angle with the roller, thus preventing paint accumulation and unevenness.

[0020] The brush, through the elasticity and friction of its soft bristles, gently combs the paint, fills in any tiny scratches that the scraper may have created, and breaks up any paint particles that may have clumped together. This sequential process allows the paint to be spread more finely and evenly at a microscopic scale, making it particularly suitable for handling paints containing fine particles.

[0021] This synergy not only improves the quality of printing and dyeing but also reduces paint waste and increases overall production efficiency.

[0022] When it is necessary to clean the scraper and brush body, restart the electric telescopic rod to drive it into the cleaning tank.

[0023] As the brush passes through the inlet, the baffle is squeezed open, allowing the scraper and brush to enter.

[0024] After the scraper and brush enter, the elasticity of the spring causes the baffle to return to the closed state, preventing the cleaning fluid from splashing and ensuring the sealing of the cleaning process.

[0025] Springs are installed both inside and outside to ensure that the scraper and brush can smoothly enter and exit the inlet, improving the reliability of operation.

[0026] During the cleaning process, the inlet pipe introduces the cleaning solution into the cleaning tank. The rinsing head sprays the cleaning solution onto the scraper and brush body for a thorough rinse. The pump draws the cleaning solution from the bottom of the cleaning tank through the return pipe. After filtration and cleaning in the filter collection box, it is returned to the inlet pipe for recycling. This design achieves the recycling of the cleaning solution, saves water resources, and reduces environmental pollution. After cleaning, a drying device can be installed on the scraper and brush body to improve work efficiency.

[0027] The filter collection box is equipped with a multi-layer composite filter screen, the structure of which includes:

[0028] Coarse filter layer: Used to intercept larger particles and impurities, preventing them from clogging subsequent filter layers.

[0029] Fine filtration layer: High-precision filtration materials, such as micron-sized stainless steel mesh or polyester fiber mesh, are used to effectively capture fine dye particles.

[0030] Adsorption layer: Adsorption materials such as activated carbon or molecular sieves are used to further adsorb dye molecules dissolved in the cleaning solution, ensuring efficient dye recovery.

[0031] This multi-layer composite filter design not only enables precise separation and recovery of dyes, but also extends the service life of the filter, reduces maintenance frequency, and improves overall recovery efficiency.

[0032] To ensure the continuity of the printing and dyeing process, multiple scrapers and brushes can be installed for periodic alternating cleaning. This design reduces downtime, improves production efficiency, and ensures the continuous operation of the printing and dyeing process.

[0033] In summary, through the aforementioned optimized design, this green dyeing and printing equipment not only achieves efficient and uniform dyeing results but also realizes resource recycling and environmentally friendly production through the coordinated operation of the cleaning and recirculation systems. The alternating use of multiple scrapers and brushes further enhances the continuity and production efficiency of the equipment. This design concept aligns with the modern dyeing and printing industry's requirements for high efficiency, environmental protection, and sustainable development.

[0034] The fabric body passes between the first dyeing roller and the second dyeing roller. The bottom end of the first dyeing roller is provided with a first material storage tank. The side of the second dyeing roller is equipped with a feeding roller. The bottom end of the feeding roller is provided with a second material storage tank.

[0035] Preferably, a storage box is installed on the end face of the operating table, a first guide pipe is connected between the storage box and the first storage pool, and a second guide pipe is connected between the storage box and the second storage pool.

[0036] Through the above technical solution:

[0037] During use, the first and second dyeing rollers are activated during the dyeing process. These two rollers rotate in the opposite direction to the fabric's movement; this design significantly enhances the friction between the fabric and the rollers. Through this reverse rotation mechanism, the dye can penetrate the fabric fibers more evenly and deeply, ensuring uniformity and consistency in the dyeing effect.

[0038] As the first and second printing rollers continue to rotate, the printing and dyeing process is divided into two symmetrical steps:

[0039] Lower surface printing: The rotation of the first printing roller drives the paint in the first storage tank to evenly print it onto the lower surface of the fabric. This design ensures that the paint on the lower surface can be fully and evenly coated, avoiding uneven paint application.

[0040] Top Surface Printing: Simultaneously, the feeding roller transfers the paint from the second storage tank to the outer wall of the second printing roller. The second printing roller then prints the paint onto the top surface of the fabric. This symmetrical printing method not only improves printing efficiency but also ensures uniform paint distribution on both sides of the fabric, thereby enhancing the overall printing quality.

[0041] To ensure the continuity of the dyeing process and a sufficient supply of paint, the storage tank replenishes paint to the first and second storage pools through the first and second guide pipes, respectively.

[0042] The first feed pipe is responsible for timely transporting the paint in the storage box to the first storage pool to ensure the continuous printing and dyeing of the lower surface.

[0043] The second feed pipe transports the paint in the storage box to the second storage pool, ensuring a sufficient supply of paint to the feeding roller and the second printing and dyeing roller.

[0044] This precise paint replenishment mechanism effectively avoids uneven printing or interruptions caused by insufficient paint. Furthermore, the amount of paint in the storage tank can be controlled in real time by the control system, dynamically adjusting the paint supply based on factors such as printing speed and fabric width, further improving the uniformity and stability of the printing process.

[0045] Through the aforementioned symmetrical printing and dyeing process and precise paint replenishment, the printing and dyeing process not only achieves efficient double-sided printing and dyeing but also ensures a high degree of uniformity in the printing and dyeing effect. This design effectively avoids common problems in traditional printing and dyeing processes such as color difference, spots, and paint accumulation, resulting in fabrics that are more consistent and perfect in both appearance and texture after printing and dyeing.

[0046] In summary, this dyeing and printing equipment achieves efficient and uniform double-sided dyeing through counter-rotating dyeing rollers, symmetrical dyeing methods, and a precise paint replenishment mechanism. This design not only improves dyeing and printing efficiency but also significantly enhances dyeing and printing quality, effectively avoiding common problems and resulting in superior dyeing and printing effects. Simultaneously, the dynamic control and recycling of paint further enhances the equipment's environmental friendliness and resource utilization, meeting the requirements of modern dyeing and printing industries for efficient, high-quality, and sustainable production.

[0047] Compared with the prior art, the beneficial effects of this utility model are:

[0048] (1) This utility model effectively improves the printing and dyeing quality and reduces paint waste by setting up structures such as a scraper, a brush, and a cleaning box. In actual operation, the scraper can accurately remove excess paint from the surface of the printing and dyeing roller, avoiding paint accumulation and ensuring that the paint is evenly distributed on the surface of the printing and dyeing roller. The brush plays a combing role for the paint, filling in the fine scratches that may be generated when the scraper is applied, and breaking up any particles that may accumulate in the paint. The coordinated operation of the scraper and the brush not only significantly improves the printing and dyeing quality, making the printed and dyed patterns clearer and the colors more uniform, but also reduces paint waste, thereby improving the overall production efficiency. The cleaning box is equipped with a rinsing component and a return component, which can rinse the scraper and the brush in all directions to prevent dye from accumulating on the scraper and the brush, so as not to affect the normal performance of the scraper and the brush.

[0049] (2) This utility model achieves double-sided dyeing of materials by setting up components such as a first dyeing roller, a second dyeing roller, and a feeding roller. During operation, the first dyeing roller rotates, driving the paint in the first storage tank and evenly dyeing it onto the lower surface of the fabric. This design ensures that the paint on the lower surface of the fabric can be fully and evenly coated, effectively avoiding the problem of uneven paint coating. The feeding roller is responsible for transferring the paint in the second storage tank to the outer wall of the second dyeing roller, and then the second dyeing roller dyes the paint onto the upper surface of the fabric. This symmetrical dyeing method not only significantly improves the dyeing efficiency but also ensures that the paint distribution on both sides of the fabric is uniform. Attached Figure Description

The liquid pump 28 is installed at the liquid outlet of the filter collection box 27, and the liquid outlet of the liquid pump 28 is connected to the liquid inlet pipe 24.

[0060] Through the above technical solution:

[0061] In use, the operating table 1 serves as the core support platform for the entire dyeing and printing equipment, providing stable support for other components. The input device 2 and the output device 3 are symmetrically arranged on both sides of the operating table 1, forming a complete feeding and discharging channel. The fabric body 4 enters through the input device 2, runs through the entire dyeing and printing process, and is finally output from the output device 3, ensuring the continuity and efficiency of the dyeing and printing process.

[0062] Before being processed by the dyeing rollers, the soybean fiber fabric body 4 needs to undergo several meticulous pretreatment processes to ensure the optimal dyeing state of the fabric:

[0073] When it is necessary to clean the scraper 13 and brush body 14, restart the electric telescopic rod 15 to drive it into the cleaning tank 16.

[0074] When passing through the opening 17, the baffle 18 is squeezed open, allowing the scraper 13 and brush body 14 to enter.

[0085] Please see Figures 1-2 As shown, the fabric body 4 passes between the first dyeing roller 5 and the second dyeing roller 6. The bottom end of the first dyeing roller 5 is provided with a first material storage tank 8, and the side of the second dyeing roller 6 is provided with a feeding roller 7.

[0093] The first feed pipe 11 is responsible for timely transporting the paint in the storage box 10 to the first storage pool 8 to ensure the continuous printing and dyeing of the lower surface.

[0094] The second feed pipe 12 transports the paint in the storage box 10 to the second storage pool 9, ensuring a sufficient supply of paint to the feeding roller 7 and the second printing and dyeing roller 6.
