Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a dyeing device for high color fastness of silk fabric. Background Technology

[0002] Silk fabric is a protein fiber material, beloved for its excellent skin-friendliness, and the demand for silk is increasing as people's living standards improve. Dyeing silk fabrics using dyeing machines is a crucial process in silk fabric production. During this process, changes in dye concentration affect the dyeing effect and colorfastness. As the dyeing process continues, the dye gradually adheres to the fabric, causing a decrease in dye concentration in the dyeing tank. This affects the uniformity of dyeing and reduces colorfastness. Existing methods to overcome this problem include dividing large bolts of silk fabric into smaller bolts for batch dyeing and periodically replenishing dye and re-dyeing. However, these methods inevitably reduce production efficiency due to production interruptions. Therefore, a new solution is needed to address this issue. Summary of the Invention

[0003] This invention overcomes the shortcomings of the prior art and provides a dyeing device for high color fastness of silk fabrics.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high color fastness dyeing device for silk fabric, comprising: a dyeing box, fabric rolling rollers located on both sides outside the dyeing box, a dyeing pool disposed at the lower end inside the dyeing box, a plurality of guide rollers disposed in the dyeing pool, and a replenishment cylinder disposed at the upper end of the guide rollers; the replenishment cylinder is used to hold the dye liquor to be replenished, and a flow guiding device is provided on both sides of the replenishment cylinder;

[0005] The flow guiding device includes: a first liquid pump and a second liquid pump located on the side of the supply cylinder away from the first liquid pump; the first liquid pump is used to guide the dye liquor in the supply cylinder to the dyeing tank, the second liquid pump is used to guide the dye liquor in the dyeing tank to the supply cylinder, and the end of the supply cylinder away from the dyeing tank is also provided with a material inlet, and the supply cylinder is also provided with a stirring device.

[0006] In a preferred embodiment of this utility model, the dyeing box is further provided with a Y-shaped heat pipe that connects the supply cylinder and the dyeing pool.

[0007] In a preferred embodiment of the present invention, the stirring device includes: a drive motor placed on one side of the supply cylinder as a power source, an output shaft fixedly connected to the output end of the drive motor, and a plurality of stirring blades fixedly connected to the output shaft; the output shaft is located at the central axis of the supply cylinder, and the distance between the Y-shaped heat pipe and the output shaft is greater than the distance between the end of the stirring blade and the output shaft.

[0008] In a preferred embodiment of the present invention, the output ends of the first liquid pump and the second liquid pump are respectively provided with a first liquid outlet pipe and a second liquid outlet pipe connecting the dyeing tank and the supply cylinder. The first liquid outlet pipe is provided with a first one-way valve that allows the supply cylinder to the dyeing tank, and the second liquid outlet pipe is provided with a second one-way valve that allows the supply cylinder to the dyeing tank.

[0009] In a preferred embodiment of the present invention, the first one-way valve and the second one-way valve include: a support rod fixedly connected inside the first or second liquid outlet pipe, and an elastic valve plate fixedly connected at the center of the support rod. The cross-sectional shape of the elastic valve plate is the same as the cross-sectional shape of the opening of the first or second liquid outlet pipe. When the first or second liquid pump is running, the elastic valve plate deforms to open a passage connecting the supply cylinder and the dyeing tank.

[0010] In a preferred embodiment of the present invention, the material inlet is connected to the upper end of the dyeing box, and an operating platform is also provided above the dyeing box, which is supported on the dyeing box by step ladder supports on both sides of the dyeing box.

[0011] In a preferred embodiment of this utility model, both the dyeing tank and the replenishment cylinder are equipped with dye liquor concentration measuring instruments.

[0012] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0013] (1) By setting a supply cylinder above the dyeing pool, the present invention can adjust the dye liquor in the supply cylinder before dyeing the silk fabric in the dyeing pool, and then neutralize the dye liquor in the supply cylinder with the dye liquor in the dyeing pool through the flow guiding device. This ensures that the concentration of dye liquor in the dyeing pool will not decrease excessively as the dyeing time progresses, thus reducing the dyeing effect. Compared with the prior art, it does not require stopping the operation of the device to adjust the dye liquor in the supply cylinder and then mix it in the dyeing pool through the flow guiding device, thus ensuring the dyeing effect while improving production efficiency.

[0014] (2) The present invention also provides a stirring device in the supply cylinder to ensure the uniformity of dye distribution in the supply cylinder and further improve the dyeing effect on silk fabrics. In addition, a first check valve and a second check valve are respectively provided at the outlet of the first and second pumps of the flow guiding device to prevent backflow of dye when the dye overflows the outlet of the first or second pump, thereby creating a safety hazard in the operation of the equipment and improving the safety of the present invention during operation.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Example: Figures 1-4As shown, a high colorfastness dyeing device for silk fabric includes: a dyeing box 1, fabric rolling rollers 2 located on both sides of the outside of the dyeing box 1, a dyeing pool 3 disposed at the lower end of the inside of the dyeing box 1, a plurality of guide rollers 4 disposed in the dyeing pool 3, and a replenishment cylinder 5 disposed on the upper end of the guide rollers 4; the guide rollers 4 are arranged in a ring array around the replenishment cylinder 5 on the dyeing pool 3 to guide the silk fabric entering from the inlet end of the dyeing box 1, the replenishment cylinder 5 is used to hold the dye liquor to be replenished, and the replenishment cylinder... Both sides of the body 5 are provided with flow guiding devices 6; the flow guiding device 6 includes: a first liquid pump 61, and a second liquid pump 62 located on the side of the supply cylinder 5 away from the first liquid pump 61; the first liquid pump 61 is used to guide the dye liquid in the supply cylinder 5 to the dyeing tank 3, and the second liquid pump 62 is used to guide the dye liquid in the dyeing tank 3 to the supply cylinder 5. The end of the supply cylinder 5 away from the dyeing tank 3 is also provided with a material inlet, and a stirring device 7 is also provided inside the supply cylinder 5.

[0023] Based on the above setup, the silk fabric is fixed on the roll rollers 2 on both sides of the outside of the dyeing box 1. Several guide rollers 4 set in the dyeing pool 3 then fix the silk fabric inside the dyeing box 1. The purpose of the supply cylinder 5 is to allow the dye liquor to be pre-mixed through the feeding port and then evenly mixed by the stirring device 7. After the dye is evenly distributed in the dye liquor, the first pump 61 draws the dye liquor into the dyeing pool 3, thereby improving the uniformity of dye distribution and enhancing the dyeing effect. Simultaneously, the supply cylinder 5 allows for the recalculation and remixing of the dye liquor with an appropriate concentration during the dyeing process. The first pump 61 and the second pump 62 neutralize the dye liquor in the dyeing pool 3 and the supply cylinder 5, preventing excessive dye consumption due to prolonged dyeing, which could lead to uneven dye absorption by the silk fabric, reducing color fastness and uniformity, and ensuring the dyeing effect of the silk fabric.

[0024] Furthermore, such as Figures 1-4As shown, the dyeing box 1 is also equipped with a Y-shaped heat pipe 8 that connects the supply cylinder 5 and the dyeing pool 3. The Y-shaped heat pipe 8 is made of copper metal with strong thermal conductivity. Through the design of the Y-shaped heat pipe 8, it can heat the dye liquor in the dyeing pool 3 and the supply cylinder 5 at the same time, so as to ensure that the dye liquor has the best temperature when it enters the dyeing pool 3, and can always maintain the best temperature in the dyeing pool 3 under the setting of the Y-shaped heat pipe 8. Specifically, the stirring device 7 includes: a drive motor 71 placed on one side of the supply cylinder 5 as a power source, an output shaft 72 fixedly connected to the output end of the drive motor 71, and several stirring blades 73 fixedly connected to the output shaft 72; the output shaft 72 is located at the central axis of the supply cylinder 5, and the distance between the Y-shaped heat pipe 8 and the output shaft 72 is greater than the distance between the end of the stirring blades 73 and the output shaft 72, so as to avoid the stirring blades 73 colliding with the Y-shaped heat pipe 8 when working, thereby improving the safety of the equipment. The purpose of the stirring device 7 is to mix the dye solution passing through the supply cylinder 5 evenly, so as to improve the uniformity of dyeing.

[0025] Furthermore, such as Figures 1-4 As shown, the output ends of the first pump 61 and the second pump 62 are respectively provided with a first outlet pipe 611 and a second outlet pipe connecting the dyeing tank 3 and the supply cylinder 5. The first outlet pipe 611 is provided with a first one-way valve 612 that can connect the supply cylinder 5 to the dyeing tank 3, and the second outlet pipe is provided with a second one-way valve that can connect the dyeing tank 3 to the supply cylinder 5. The first one-way valve 612 and the second one-way valve include: a support rod 6121 fixedly connected in the first outlet pipe 611 or the second outlet pipe, and an elastic valve plate 6122 made of rubber fixed to the center of the support rod 6121 by screws. The cross-sectional shape of the elastic valve plate 6122 is the same as the cross-sectional shape of the pipe opening of the first outlet pipe 611 or the second outlet pipe. When the first pump 61 or the second pump 62 is running, the elastic valve plate 6122 deforms and opens a passage connecting the supply cylinder 5 and the dyeing tank 3.

[0026] Based on the above configuration, when the first pump 61 and the second pump 62 are running, the dye liquor can be guided through the inlet. When the first pump 61 and the second pump 62 stop running, the elastic valve plate 6122 will return to the state of adhering to the inner wall of the first outlet pipe 611 and the second outlet pipe under the action of elastic deformation, thereby blocking the pipe opening and preventing the dye liquor from flowing back when it overflows the first outlet pipe 611 or the second outlet pipe, thus improving the safety performance of the equipment.

[0027] Furthermore, such as Figures 1-4As shown, the feeding port is connected to the upper end of the dyeing roll box 1. Above the dyeing roll box 1, there is also an operating platform 9 supported by step ladders on both sides of the dyeing roll box 1. This provides a platform for workers to conveniently feed dyes and other materials from the feeding port at the upper end into the replenishment cylinder 5 to complete the preparation of the dye liquor. In addition, referring to the existing technology, both the dyeing roll pool 3 and the replenishment cylinder 5 are equipped with dye liquor concentration measuring instruments that use the principle of different conductivity caused by different dye liquor concentrations to measure the dye liquor concentration. This is used to monitor the concentration of the dye liquor in real time, so as to facilitate the observation of the consumption of dye liquor during dyeing and to facilitate the re-ratio in the replenishment cylinder 5. Then, it is neutralized with the dye liquor in the dyeing roll pool 3 to ensure that the dye in the dyeing roll pool 3 always has a suitable concentration during the dyeing process, thereby improving the dyeing effect of silk fabrics and improving the uniformity and color fastness of dyeing.

[0028] Working principle: Two fabric rolling rollers 2 on both sides of the outer side of the dyeing box 1 are used to place and roll up the dyed fabric, respectively. The guide roller 4 is used to guide the dyed fabric. Before dyeing, the dye concentration can be adjusted in the supply cylinder 5. Then, under the action of the stirring device 7 and the Y-shaped heat conduction pipe 8, the dye in the supply cylinder 5 is stirred evenly and heated to ensure that the dye temperature is appropriate and the dye is evenly distributed. During the dyeing process, the dye liquor can also be prepared again in the supply cylinder 5 based on the dye consumption data obtained from the dye liquor concentration measuring instrument. The first pump 61 and the second pump 62 are used to neutralize the dye liquor in the supply cylinder 5 and the dyeing tank 3, so as to avoid the dye concentration in the dyeing tank 3 becoming insufficient and reducing the dyeing effect of the fabric as the dyeing time goes by. Compared with the existing technology, there is no need to dye in batches or pause dyeing to replenish dye in the middle, which improves the production efficiency. The first outlet pipe 611 and the second outlet pipe of the first pump 61 and the second pump 62 are equipped with elastic valve plates 6122 to prevent the backflow of dye and ensure the safety of the equipment.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
