Description

Technical Field

[0001] The invention relates to the technical field of cloth dyeing equipment, in particular to a sample dyeing machine for processing textile materials. Background Art

[0002] The dyeing of fabric samples has the following important purposes: determining the appropriate dyeing formula, conducting dyeing tests on samples, trying different dye types, dosages, and auxiliaries, exploring the best formula that can make the target fabric achieve the ideal color effect, providing an accurate reference for subsequent large-scale production, ensuring the consistency and accuracy of product color, testing color fastness performance, simulating actual use and subsequent processing conditions on samples, such as friction, washing, sun exposure, etc., testing color fastness after dyeing, discovering possible fading problems in advance, so as to adjust the formula or process and ensure that the final product meets quality standards. When dyeing samples, the exhaust dyeing method is usually used. The fabric sample is placed in the prepared dye solution so that the dye can evenly penetrate into the fabric fiber. It is usually necessary to control parameters such as the temperature of the dye solution, the exhaust dyeing time, and the ratio of the dye solution to the sample. For example, the temperature of the dye solution is generally set according to the characteristics of the dye and the material of the fabric. When using reactive dyes on cotton fabrics, it is often controlled at around 60°C. The dyeing time may range from 30 minutes to 1 hour. During this period, proper stirring is required to ensure uniform dyeing. After dyeing is completed, the dyed samples can be processed subsequently, including cleaning to remove excess dyes and auxiliaries that are not fixed on the surface, selecting appropriate drying methods such as natural drying and low-temperature drying, and using friction, water washing, sun exposure and other test methods to test the color fastness of the dyed samples. The test results are recorded and compared with the expected standards. If they do not meet the requirements, the reasons are analyzed and the dyeing formula or process is adjusted and optimized.

[0003] At present, when dyeing small samples, the small sample fabric pieces are usually placed directly in a container filled with dye solution. After dyeing, subsequent processing such as cleaning, drying and color fastness testing are all carried out separately. Not only does it require a large amount of dye solution, but the cleaning and drying processes also require the small sample fabric pieces to be disassembled and transferred, resulting in dripping of dye solution that has not dried completely and causing contamination. In addition, the operation process is cumbersome and slow. Summary of the Invention

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figures 1-11 As shown, the sample dyeing machine for textile material processing provided by the present invention includes a dyeing vat 1, a cover plate 5 and an electric water tank 9 matched with the upper end of the dyeing vat 1, and further includes:

[0039] The fabric fixing fixture is arranged in the dye vat 1 and is composed of an inner ring 18 and an outer ring 19. The fabric fixing fixture can immerse the fabric 28 in the dye solution in a tensioned state, so that the fabric 28 is suspended in the dye solution and does not contact the inner wall of the dye vat 1;

[0040] The driving mechanism is installed at the center of the cover plate 5 through the sleeve 20 and is connected to the inner ring 18 of the cloth fixing fixture. The driving mechanism provides power to rotate the cloth 28 in the cloth fixing fixture to evenly contact the dye solution, and at the same time, the dye solution can be stirred homogeneously;

[0041] The brushing assembly is arranged in the inner ring 18 and above the cloth 28, and is used to rub the cloth 28 for color fastness detection.

[0042] This technical solution solves the problem that traditional small-sample printing and dyeing tests to determine the ratio of different dyes and auxiliaries, as well as the effects of process conditions such as temperature, time, and pH on the printing and dyeing results, require the use of large amounts of prepared dye liquor, and manual subsequent processing of the dyed samples, such as cleaning, drying, and color fastness testing. This small-sample dyeing machine, through its multifunctional collaborative design, ensures that the dyed fabric samples 28 remain stable and wrinkle-free during the dyeing process, effectively reduces the amount of dye liquor used without contacting the dye vat 1, and can also perform subsequent processing processes such as cleaning, drying, and color fastness testing within the vat 1.

[0043] Specifically, the fabric fixing assembly, the driving mechanism, and the brushing assembly cooperate with each other to support and fix the fabric sample 28 during the printing and dyeing process, ensuring that the fabric 28 does not contact the dye vat 1. The fabric 28 in the dye vat 1 can also be rotated by the fabric fixing fixture, thereby achieving uniform mixing of the dye solution, avoiding the segregation of the dye and the auxiliary agent, and making the fabric 28 evenly contact the dye solution, so that the pigment can be evenly immersed in the fabric 28 to achieve the purpose of uniform coloring.

[0044] Specifically, such as Figure 3-Figure 5 As shown, the outer ring 19 of the fabric fixing fixture is sleeved with the inner ring 18, and a platform 37 for pressing the fabric 28 is provided on the inner side of the outer ring 19. The lower end of the inner ring 18 is provided with an annular protrusion 27 for pressing the fabric 28 down to be flush with the lower end of the outer ring 9. The annular protrusion 27 cooperates with the inner side of the platform 37 to form a clamping portion for fixing the fabric 28. The clamping portion is an annular structure, and a gap of 0.5-1.2mm needs to be reserved between the clamping portions to avoid excessive squeezing of the fabric 28. Anti-slip grooves are provided on the platform 37, and corresponding anti-slip grooves are also provided on the lower end of the inner ring 18. Rubber protrusions 34 are provided at the edge of the inner ring 18, and an annular groove 36 cooperating with the rubber protrusion 34 is provided on the inner side of the outer ring 19. The depth of the annular groove 36 is 2mm.

[0045] The inner ring 18 has multiple rotating shafts at its upper end. Locking plates are rotatably connected to the shaft walls of each of these shafts. A braking portion 26 is provided at one end of the locking plate, and a locking portion 25 is provided on one side of the locking plate. A slot 35 is provided on the inner side of the outer ring 19 to engage with the locking portion 25. The slot 35 is horizontally defined and has a depth of 5 mm.

[0046] like Figure 4In the process, the inner ring 18 and the outer ring 19 can be used to clamp the edges of the pre-processed fabric 28 sample with a diameter of 20-25 cm. After clamping, a circular colored area with a diameter of 18 cm is formed in the inner ring 18. When the fabric 28 fixing component is at the lower end, there is a distance of 5 mm from the bottom of the dye vat 1. During printing and dyeing, the dye liquid can be added to the upper end of the outer ring 19. In this way, the amount of dye liquid used can be greatly reduced. In addition, the fabric 28 does not contact the inner wall of the dye vat 1 during the printing and dyeing process, so as to avoid the fabric 28 being in the dye liquid with uneven temperature affecting the coloring effect.

[0047] Specifically, such as Figure 2 and Figure 3 As shown, the driving mechanism provided in the above technical solution includes a sleeve 20, which is rotatably connected to the center of the cover plate 5 through a sealed bearing, and a positioning plate 23 is fixedly connected to the tube wall of the sleeve 20. An external thread 24 is provided on the tube wall of the sleeve 20 below the positioning plate 23. The rotation direction of the external thread 24 is designed to be opposite to the rotation direction of the motor 6 to avoid loosening during rotation. The sleeve 20 is fixedly connected to the cross 13 through the external thread 24, and an arc-shaped plate is provided at the end of the cross 13. The arc-shaped plate is fixedly connected to the inner side of the inner ring 18 by bolts, and a plurality of spoilers 14 are fixedly connected to the upper end of the cross 13, which can disturb the airflow inside the dye vat 1 when rotating.

[0048] In addition, a first pulley 21 is fixedly connected to the tube wall of the sleeve 20, a belt 10 is wrapped around the side wall of the first pulley 21, a second pulley 22 is wrapped around the inner side of the belt 10, and the upper end of the cover plate 5 is fixedly connected to the motor 6, and the output end of the motor 6 is fixedly connected to the upper end of the second pulley 22 coaxially.

[0049] During driving, the motor 6 drives the second pulley 22 to make the belt 10 drive the first pulley 21 to rotate, the rotation of the first pulley 21 drives the sleeve 20 to rotate the cross 13, and the rotation of the cross 13 drives the inner ring 18 and the outer ring 19 to rotate, so that the dye liquid in the dye vat 1 can be homogeneously mixed at different rotation speeds, and the fabric 28 can be cleaned, dried and color fastness tested.

[0050] Specifically, such as Figure 2 and Figure 3As shown, the brushing assembly provided in the above technical solution includes a push rod 30, which is sleeved in the sleeve 20, and the lower end of the push rod 30 passes through the sleeve 20 and extends into the dye vat 1, and a plate brush 29 is provided in the dye vat 1. A fixing bolt is sleeved at the center of the plate brush 29 through a countersunk hole, and the lower end of the push rod 30 is fixedly connected to the fixing bolt through a threaded hole, and the upper end of the cover plate 5 is fixedly connected to the bracket, and the upper end of the bracket is fixedly connected to the first electric push rod 7, and the output shaft of the first electric push rod 7 is fixedly connected to the upper end of the push rod 30, and a limit plate 31 is fixedly connected to the rod wall of the push rod 30, and the side walls of the limit plate 31 are symmetrically fixedly connected to two sliding sleeves, and guide rods 32 are sleeved in the two sliding sleeves, and the upper end of the guide rod 32 is fixedly connected to the lower end of the bracket.

[0051] When conducting color fastness testing, the first electric push rod 7 is started to drive the push rod 30 to move downward. When the push rod 30 moves downward, it drives the brush 29 to move downward and contact the cloth 28 fixed in the inner ring 18. At this time, the driving mechanism can be used to drive the cloth fixing clamp to rotate the cloth 28. During rotation, it can rotate in different liquids (dye solution and clean water), and can be brushed to test the color fastness of the dyed sample product when cleaning.

[0052] Specifically, in order to make the temperature of the dyeing solution balanced and controllable, this technical solution adopts a water bath heating method, and the hot water used for heating is an external circulating water supply, such as Figure 10 As shown, one side of the electric hot water tank 9 is fixedly connected to a water inlet pipe, and a water pump 33 is fixedly connected to the pipe wall of the water inlet pipe. The water pump 33 adopts a high-temperature resistant water pump, and the output end of the water pump 33 is fixedly connected to the lower end of the dye vat 1 through a joint. The other side of the electric hot water tank 9 is fixedly connected to a return pipe, and one end of the return pipe is fixedly connected to the lower end of the dye vat 1 through a joint. Temperature sensors 11 are installed on the upper ends of the electric hot water tank 9 and the cover plate 5. The two temperature sensors 11 are installed at different positions for testing the temperature difference and independently detecting the water temperature at the heat source and the temperature in the dye vat 1. Through the circulating pumping of the water pump 33, the hot water inside the electric hot water tank 9 can circulate in the heat exchange chamber 12 in the dye vat 1. At this time, the heat is transferred to the dye liquid inside it through the dye vat 1, so that the temperature of the dye liquid can be raised to the test set temperature;

[0053] On the other hand, refer to Figure 7-Figure 9The dye vat 1 is provided with a double-layer structure, a heat exchange chamber 12 is provided inside, a heat exchange tube 4 is provided in the heat exchange chamber 12, both ends of the heat exchange tube 4 extend to the outside of the dye vat 1, the upper end of the cover plate 5 is fixedly connected to an air pump 8, the input end of the air pump 8 is fixedly connected to one pipe opening of the heat exchange tube 4 through a hose, the upper end of the cover plate 5 is fixedly connected to a bent pipe, one end of the bent pipe is fixedly connected to the output end of the air pump 8, so that the air in the heat exchange tube 4 can be extracted at any time by the air pump 8. When the air flows, heat exchange can be realized to take away the heat in the hot water in the heat exchange chamber 12, which can not only transport the hot air to the dye vat 1 to achieve drying of the fabric 28, but also stop pumping hot water when the water level is high, and remove the bent pipe to discharge the hot air into the air, so that the temperature of the hot water in the heat exchange chamber 12 can be quickly reduced by the flowing air, and finally the temperature of the dye solution in the dye vat 1 is gradually reduced, thereby achieving the purpose of timely regulating the temperature of the dye solution.

[0054] Specifically, in order to facilitate the disassembly of samples and switch between multiple working modes, the specific technical solutions are as follows: Figure 7-9 As shown, the upper end of the cover plate 5 is fixedly connected to two connecting plates 3, and the lower ends of the two connecting plates 3 are fixedly connected to the second electric push rods 2 that can push the cover plate 5 up and down. The lower end of the dye vat 1 is fixedly connected to a plurality of legs, and the two second electric push rods 2 are fixed on two of the legs. The bottom of the dye vat 1 is provided with a concave surface, and the concave surface is fixedly connected to a water outlet pipe 15 for discharging waste liquid (dye liquid and cleaning waste water). A water valve is installed on the pipe wall of the water outlet pipe 15. The upper end of the cover plate 5 is respectively fixedly connected to a water injection pipe 16 for adding clean water to wash fabric samples and a feeding pipe 17 for adding dyeing auxiliary materials such as auxiliaries.

[0055] The specific functions and processes that can be achieved by this technical solution are as follows:

[0056] 1. Use the immersion dyeing method to dye the sample. The specific process is as follows:

[0057] 1. Dyeing treatment: first process the test sample into a piece of cloth with a diameter of appropriate size (20-25cm), first lay it flat on the platform 37 of the outer ring 19, check for wrinkles after laying it flat, then buckle the inner ring 18 into the outer ring, use the inner ring 18 and the outer ring 19 to press the cloth together, and finally use the locking piece and the card slot 35 to further lock and fix it. After completion, use the threaded hole on the cross 13 to directly screw it on the external thread 24 at the lower end of the sleeve 20 until the upper end of the cross 13 contacts the positioning plate 23, and use the fixing bolt to fix the brush 29 to the lower end of the push rod 30. In this way, the installation and fixation of the cloth 28 are completed. After that, the second electric push rod 2 can be started to drive the cover plate 5 to move down to the bottom dead point, so that the cloth can be immersed in the dye solution for printing and dyeing testing.

[0058] 2. Drying process: After the dyeing time is reached, open the water valve to discharge the dye liquid from the outlet pipe 15, and start the second electric push rod 2 to drive the cover plate 5 to move up to Figure 8 , so that the cloth is separated from the dye liquid, and at the same time, the driving mechanism can be started to make the cloth fixing clamp rotate the cloth 28 quickly. During the rotation, the dye liquid immersed in the cloth 28 can be discharged. At the same time, the air pump 8 can be started to extract the hot air in the heat exchange tube 4 and discharge it into the dye vat 1. In this way, the gas flow in the dye vat 1 can take away the moisture in the cloth 28, and the air is discharged from the water outlet pipe 15. After 10-15 minutes, the second electric push rod 2 can be operated to move the cover plate 5 to the top dead center. At this time, the dyed cloth 28 is exposed to the air, which is convenient for technicians to observe and monitor the sample. The coloring situation is to achieve the expected dyeing effect, and then the second electric push rod 2 is controlled to move the cover 5 downward. At this time, the cloth 28 is in the middle part of the dye vat 1, and clean water is added from the water injection pipe 16. The clean water is used to clean the cloth 28. At this time, the cloth 28 can be kept rotating at a low speed. After the cleaning is completed, the waste water can be discharged from the drain pipe 15. After the waste water is drained, the rotation speed of the cloth 28 is increased, and the air pump 8 is used to continue to extract hot air and transport it to the dye vat 1 to dry the cloth 28. After drying, the final color of the cloth 28 is tested, and the dyeing operation of the sample can be completed.

[0059] 3. Color fastness test. After the color of the sample meets the standard, the cover plate 5 is moved down to the bottom dead center by the second electric push rod 2. At this time, clean water can be added, and the driving mechanism is started to drive the cloth fixing clamp to rotate the cloth 28. At the same time, the first electric push rod 7 is started to push the top rod 30 downward to make the brush 29 contact the cloth 28. At this time, the rotating cloth 28 rubs against the brush 29 relative to each other, so that brushing can be achieved in water. After brushing for a certain period of time, it can be dried to facilitate observation of whether there is color difference on the surface of the cloth. Since the length of the brush 29 is smaller than the diameter of the cloth, a circular test area can be formed in the middle of the cloth. Obviously, an annular contrast area is formed between the outer side of the test area and the inner ring 18. In this way, observation can be achieved on the same cloth to check the color fastness of the dyed sample color under brushing.

[0060] From the above description, it can be seen that compared with the dyeing test of the prior art, the present technical solution can realize the dyeing test of small samples in a limited space using limited materials, which not only saves dyeing materials, but also reduces the wastewater during post-dyeing treatment and reduces the difficulty of sewage treatment. It can also perform color fastness tests, and during the test, a comparison area can be reserved for the convenience of technicians.

[0061] like Figure 11The figure shows a simple electronic control module adopted in the present technical solution. The control host is equipped with a PLC controller for controlling the first electric push rod 7, the second electric push rod 2, the motor 6, the water pump 33, the air pump 8 and the electric water tank 9. It can set the speed of the motor 6, the lifting height of the first electric push rod 7 and the second electric push rod 2, and the switching of the water pump 33 and the air pump 8. This part of the control can be solved by using the existing control system and will not be elaborated here.

[0062] It should be noted that the maximum heating temperature of the electric water tank 9 is 85°, the flow rate of the water pump 33 is 20L / min-30L / min, the flow rate of the air pump 8 is 0.2-20L / min, the motor 6 adopts a stepping motor, the speed during dyeing treatment is controlled at 100 rpm, and the speed during drying treatment is set at 1000 rpm. During the drying stage, the telescopic length of the second electric push rod 2 is set to 1 / 4 of the telescopic stroke.

[0063] It should be noted that the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
