Description

Technical Field

[0001] The invention relates to the technical field of textile testing equipment, in particular to a dye extraction device for textile testing and an extraction method thereof. Background Art

[0002] Textile testing refers to the process of inspecting and analyzing the quality, safety, performance, and composition of textiles through professional technical means. This process aims to ensure that textiles comply with relevant standards and regulations, safeguard consumer rights, and promote the healthy development of the industry. In textile testing, dye extraction refers to the process of separating, dissolving, or releasing dye components from textile fibers through physical or chemical methods. It is a key pretreatment step in chemical safety testing, such as analysis of banned dyes and hazardous chemicals. Its purpose is to release the dye from the fiber matrix, allowing subsequent instrumental analysis, such as chromatography and mass spectrometry, to accurately determine harmful substances in the dye, such as azo dyes, allergenic dyes, and heavy metals.

[0003] Chinese patent publication number CN216816216U discloses a device for extracting azo dyes from textiles. The device comprises two supporting mechanisms, with a collection drum positioned between them. A motor is located at the bottom of the collection drum, with a water outlet pipe connected to the interior of the collection drum on one side of the motor. A dewatering drum is located within the collection drum, with the motor output shaft coaxially connected to the dewatering drum. The outer wall of the dewatering drum is provided with a number of circular holes arranged in a circular pattern with equal spacing. The device facilitates the immersion of textiles by providing a dewatering drum and a sleeve, promoting thorough mixing of clean water and / or a reagent, and accelerating the extraction of azo dye components from textiles by the reagent. The dewatering drum rotates, causing the mixed liquid to escape from the dewatering drum and enter the collection drum. Finally, a collection bottle collects the target liquid, facilitating subsequent testing. This device achieves accurate extraction of azo dyes from textiles, avoids the need for multiple transfers of textiles during testing, and improves the product's practicality.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes an embodiment of the present invention based on its overall structure.

[0020] Reference Figures 1 to 9In an embodiment of the present invention, a dye extraction device for textile testing includes: a support base 1, an outer barrel 2 is clamped on the top of the support base 1, a lower press seat 3 for placing a textile sample is provided at the bottom end of the outer barrel 2, a driving member 4 is provided on the outer barrel 2, and an upper press seat 5 is provided on the driving member 4. The upper press seat 5 can be driven downward by the driving member 4 to squeeze and rub the textile sample on the lower press seat 3.

[0021] A placement groove 31 is provided at the top of the lower press seat 3. The cross-section of the placement groove 31 is W-shaped. A circulation groove 32 is provided through the inner wall of the placement groove 31. There are multiple groups of circulation grooves 32, which are evenly distributed on the inner wall of the placement groove 31. Through the setting of the W-shaped placement groove 31, the liquid can flow to the circulation groove 32 under the guidance of its inclined surface during the precipitation of textile dye, and flow into the bottom end of the outer barrel 2 through the circulation groove 32. A cavity 33 is provided at the bottom end of the lower press seat 3. There are multiple groups of cavities 33 and they are evenly distributed at the bottom end of the lower press seat 3. The cavity 33 is in an inverted convex shape. A group of guide rods 34 are slidably inserted in each group of cavities 33. The guide rods 34 are in an inverted convex shape. The inverted convex structural design of the guide rods 34 and the cavities 33 can prevent the guide rods 34 from moving out of the cavity 33. The bottom end of the guide rod 34 passes through the cavity 33 and is fixedly connected to a connecting block 35. The connecting block 35 is conical to prevent liquid from accumulating on its top during drainage. A group of springs 2 36 is sleeved on the outside of each group of guide rods 34. The upper and lower ends of the springs 2 36 are respectively in contact with the bottom end of the lower pressure seat 3 and the top end of the connecting block 35. Through the setting of the springs 2 36 and the guide rods 34, when the lower pressure seat 3 and the upper pressure seat 5 squeeze the textile sample, the lower pressure seat 3 can adaptively move downward to match textile samples of different thicknesses. The bottom end of the connecting block 35 is fixedly connected to a support cylinder 37, and the bottom end of the support cylinder 37 is fixedly connected to the bottom end of the inner part of the outer barrel 2. A drainage groove 38 is provided on the side end of the support cylinder 37. There are multiple groups of drainage grooves 38 and they are evenly distributed on the side end of the support cylinder 37. A guide groove 21 is provided at the bottom end of the outer barrel 2. The guide groove 21 is an inverted cone. The bottom end of the support cylinder 37 is fixedly connected to the top of the guide groove 21, and the drainage groove 38 is connected to the guide groove 21. A discharge pipe 22 is connected to the bottom end of the outer barrel 2. The discharge pipe 22 is arranged directly below the support cylinder 37 and is on the same axis as the support cylinder 37. The discharge pipe 22 is connected to the lowest end of the inverted cone-shaped guide groove 21. When the textile sample is placed in the W-shaped placement groove 31, the inclined surface design of the W-shaped cross-section guides the liquid to flow along the inclined surface into the flow groove 32 evenly distributed on the inner wall when the sample is soaked. The bottom end of the guide rod 34 is fixed to the support tube 37 through a conical connecting block 35, and the spring 2 36 arranged on the outside provides elastic support. If the sample thickness is different, the lower press seat 3 can slide up and down along the guide rod 34. When the sample is thicker, the lower press seat 3 overcomes the elastic force of the spring 2 36 and moves downward. When the sample is thinner, the spring elastic force supports it to maintain its height. Through this adaptive adjustment, the upper press seat 5 and the lower press seat 3 are always in line with the sample thickness. During the extrusion process, the liquid flows into the outer barrel 2 through the circulation groove 32, and is finally discharged from the discharge pipe 22 through the drainage groove 38 and the guide groove 21 at the side end of the support tube 37, thereby realizing the collection of the dye solution.

[0022] The above scheme is adopted: through the cooperation of the W-shaped placement groove 31 and the circulation groove 32, the inclined surface diversion principle is used to accelerate the flow of liquid, avoid the retention of medicine, ensure the full immersion of the sample, and improve the efficiency of dye precipitation. The limiting structure of the inverted convex cavity 33 and the guide rod 34, combined with the elastic support of the spring 2 36, enables the lower pressure seat 3 to automatically match textile samples of different thicknesses without manual adjustment, thereby enhancing the adaptability of the device to diversified test samples and avoiding sample damage or equipment failure caused by excessive squeezing. The design of the conical connecting block 35 prevents liquid from accumulating at its top during drainage, and cooperates with the drainage groove 38 at the side end of the support tube 37 and the inverted conical guide groove 21 to form a smooth liquid discharge channel, ensuring that the dye solution is quickly and thoroughly collected. The overall structure realizes pressure adaptation through mechanical linkage, reduces manual intervention, improves the degree of automation and operational stability of the detection process, and provides efficient and reliable hardware support for textile dye extraction.

[0023] The driving member 4 includes a lifting groove 41 provided on the inner wall of the outer barrel 2. The lifting groove 41 is spirally wound around the inner wall of the outer barrel 2. The inner wall of the outer barrel 2 is also provided with a rotating groove 42. The rotating groove 42 is O-shaped and is located below the lifting groove 41. The bottom end of the lifting groove 41 is connected to the rotating groove 42. A receiving groove 43 is provided at the bottom end of the rotating groove 42. The receiving groove 43 is provided below the connection between the lifting groove 41 and the rotating groove 42. A spring 44 is fixedly connected to the bottom end of the receiving groove 43. The spring 44 is fixed to the bottom end of the receiving groove 43. There are multiple groups of springs 44 evenly distributed at the bottom of the receiving groove 43. A top block 45 is fixedly connected to the top of the spring 1 44. The height of the top block 45 is the same as that of the rotating groove 42. The plane projection of the top block 45 is an isosceles triangle. The top block 45 is designed to be arc-shaped, and the inclined surfaces on both sides are arc surfaces. Under the support of the spring 1 44, the top of the top block 45 abuts against the bottom of the connection between the lifting groove 41 and the rotating groove 42, so that the bottom of the lifting groove 41 and the arc surface of one side of the top block 45 are on the same spiral trajectory. The driving member 4 also includes a mounting plate 46 fixed to the top of the outer barrel 2, and a motor 47 is fixedly connected to the top of the mounting plate 46. The output end of the motor 47 passes through the mounting plate 46 and is fixedly connected to a rotating rod 48. The bottom end of the rotating rod 48 passes through the upper pressure seat 5 and is rotatably plugged with the lower pressure seat 3. The outer side of the rotating rod 48 is fixedly connected to a linkage plate 49. The linkage plate 49 is provided with four groups and is symmetrically distributed on the outer side of the rotating rod 48. The cross-section of the rotating rod 48 and the linkage plate 49 is cross-shaped. The bottom end of the linkage plate 49 is aligned with the inner bottom of the placement groove 31. The ends are fitted together, the length of the linkage plate 49 is smaller than the rotating rod 48, the linkage plate 49 passes through the upper pressure seat 5, and is slidably plugged with the upper pressure seat 5. A guide plate 410 is fixedly connected to the outside of the upper pressure seat 5. The guide plate 410 is spiral and adapted to the lifting groove 41. One end of the guide plate 410 is slidably plugged with the lifting groove 41. When the guide plate 410 enters the rotating groove 42 with the guidance of the lifting groove 41, it continues to rotate until it abuts against the arc surface of one side of the top block 45. Under the abutment action, the top block 45 is pressed down, so that the guide plate 410 is lifted from the top The guide plate 410 passes through the block 45, thereby continuing to rotate. When the motor 47 drives the guide plate 410 to reverse, the guide plate 410 abuts against the arc surface of one side of the top block 45. Since the bottom end of the inner bottom of the lifting groove 41 and the arc surface of the side of the top block 45 are on the same spiral track, under its guidance, the guide plate 410 rotates in the opposite direction and returns to the lifting groove 41, and moves upward under the action of the reversal. A connecting groove 414 is provided at the bottom end of the placement groove 31, and the connecting groove 414 passes through the placement groove 31 and the lower pressure seat 3. The bottom end of the rotating rod 48 is connected to the bottom end of the lifting groove 41. The connecting groove 414 is rotatably plugged in, and the bottom end of the guide plate 410 is fixedly connected to the mounting shaft 411. The mounting shaft 411 is in an inverted T shape. The outer surface of the mounting shaft 411 is rotatably connected to the sleeve 412. The side end of the sleeve 412 is fixedly connected to the fan blade 413. The fan blade 413 is provided in three groups and is evenly distributed on the side end of the sleeve 412. When the guide plate 410 rotates in the rotating groove 42, it drives the mounting shaft 411 to rotate synchronously, so that the water flow pushes the fan blade 413 and the sleeve 412 to rotate around the mounting shaft 411, stirring the water flow.The water flow is uniformly mixed with the precipitated dye. When the motor 47 is started and the rotating rod 48 is driven to rotate, the cross-shaped linkage plate 49 on the outside thereof slides and plugs into the cross-shaped slot 53 of the upper press seat 5, driving the upper press seat 5 to rotate synchronously. The spiral guide plate 410 on the outside of the upper press seat 5 cooperates with the spiral lifting groove 41 on the inner wall of the outer barrel 2, so that the upper press seat 5 moves downward along the axis of the lifting groove 41 during rotation until the guide plate 410 reaches the bottom end of the lifting groove 41 and cuts into the O-shaped rotating groove 42. At this time, the top block 45 in the rotating groove 42 is supported by the spring 1 44, and its top arc The surface of the guide plate 410 is aligned with the bottom track of the lifting groove 41. After entering the rotating groove 42, the guide plate 410 continues to rotate horizontally. When it abuts the top block 45, it presses it down and compresses the spring 1 44, so that it can pass smoothly and maintain the horizontal rotation state, realizing the squeezing and friction of the upper pressure seat 5 on the sample. When the dye extraction is completed and it needs to move up, the motor 47 reverses, and the guide plate 410 contacts the other side of the curved surface of the top block 45. Because this curved surface is collinear with the spiral track at the bottom of the lifting groove 41, the guide plate 410 rotates in the opposite direction under the guidance of the top block 45 and re-inserts into the lifting groove 41, driving the upper pressure seat 5 to rise along the spiral track.

[0024] The above scheme is adopted: the rotational motion of the motor 47 is converted into the spiral lifting motion of the upper pressure seat 5 through the cooperation of the spiral lifting groove 41 and the guide plate 410, and precise axial displacement control can be achieved without a complex transmission mechanism, simplifying the mechanical structure. The trajectory switching device composed of the top block 45 and the spring 44 can automatically complete the connection and separation of the lifting groove 41 and the rotating groove 42, ensuring that the upper pressure seat 5 maintains horizontal rotation during the extrusion stage and returns along the original trajectory during the reset stage to avoid motion interference. The fan blade 413 at the bottom end of the guide plate 410 automatically rotates with the water flow in the rotating groove 42, and can stir the liquid without additional power, promote the mixing of dye and clean water, and avoid manual intervention. The overall drive system controls the movement direction of the upper pressure seat 5 through the forward and reverse rotation of the motor 47, combined with the automatic sealing and opening of the drainage groove 38 by the closing cylinder 55.

The bottom end of the closing cylinder 55 is adapted to the top end of the guide groove 21, and a rubber sealing ring is embedded in the bottom end and the inside of the closing cylinder 55, so that when the closing cylinder 55 moves down with the upper pressure seat 5, the drainage groove 38 is blocked.

Since the fixed grooves 514 are spherical, the through hole of the fixed groove 514 passing through the medicine box 57 is circular, and its diameter is smaller than the diameter of the spherical fixed groove 514. The diameter of the ball 515 is smaller than the diameter of the spherical fixed groove 514, so that the ball 515 in the fixed groove 514 will not fall. When the upper press seat 5 rotates in the rotating groove 42, the ball 515 abuts against the textile sample and rotates with the rotation of the upper press seat 5, so that the medicine in the medicine storage cavity 58 flows out as the ball 515 rotates and is evenly smeared on the textile sample by the ball 515. The medicine box 57 is inserted into the mounting groove 51 at the top of the upper press seat 5.Its bottom V-shaped structure is flush with the extrusion platform 516. The medicine in the medicine storage chamber 58 is temporarily stored under the ball bearing 515. During extrusion, the ball bearing 515 moves upward and rotates due to the reaction force of the sample, evenly applying the medicine to the sample surface. As the upper pressing seat 5 rotates, the bottom sealing cylinder 55 moves downward, sealing the drainage groove 38 of the support cylinder 37 through the rubber sealing ring to prevent premature discharge of liquid. When the motor 47 is reversed, the upper pressing seat 5 rises along the lifting groove 41, and the sealing cylinder 55 moves upward synchronously to expose the drainage groove 38, allowing the mixed dye liquid to be discharged from the discharge pipe 22 through the guide groove 21.

[0026] The above scheme is adopted: through the adaptation structure of the extrusion table 516 and the W-shaped placement groove 31, uniform friction and pressure are applied to the sample through rotation to ensure that the dye is fully extracted. The limit installation of the medicine box 57 and the linkage design of the ball 515 allow the medicine to be released as needed and evenly applied during the extrusion process, avoiding medicine waste and manual intervention. The sealing cooperation between the sealing cylinder 55 and the drainage groove 38 automatically controls the liquid discharge timing through mechanical linkage to prevent the loss of medicine during the extraction process and ensure the stability of the liquid environment during the immersion and extrusion stages.

[0027] A method for extracting dyes for textile testing, using a dye extraction device for textile testing, includes the following extraction steps: First, pour the required medicine into the medicine storage cavity 58 of the medicine box 57. Due to the weight of the medicine itself, the ball 515 at the bottom end of the medicine storage cavity 58 will produce a downward squeezing force, so that the ball 515 is tightly fitted into the small hole at the bottom end of the medicine box 57 at the fixing groove 514, thereby blocking the small hole and preventing the medicine from flowing out before the operation is started. Next, align the medicine box 57 with the mounting groove 51 at the top end of the upper pressure seat 5, so that the limiting block 59 at the side end of the medicine box 57 is accurately plugged into the limiting groove 52 on the inner wall of the mounting groove 51 to ensure that the position of the medicine box 57 in the mounting groove 51 is stable. Then, insert the plug post 512 at the bottom end of the upper cover 513 into the plug hole 511 in the flush groove 510 at the top end of the medicine box 57, so that the upper cover 513 is tightly fitted with the flush groove 510, and the installation of the medicine box 57 is completed. Then the motor 47 is turned on, and the output end of the motor 47 drives the rotating rod 48 to start rotating. Since the linkage plate 49 on the outside of the rotating rod 48 is slidably plugged into the slot 53 of the upper pressure seat 5, and the linkage plate 49 is symmetrically distributed, the upper pressure seat 5 is driven to rotate synchronously. The guide plate 410 on the outside of the upper pressure seat 5 is spiral and adapted to the lifting groove 41 on the inner wall of the outer barrel 2. During the rotation process, the guide plate 410 drives the upper pressure seat 5 to move downward along the axis direction of the rotating rod 48 along the spiral trajectory of the lifting groove 41. When the guide plate 410 moves to the bottom end of the lifting groove 41 and enters the rotating groove 42, the upper pressure seat 5 continues to rotate horizontally with the rotating rod 48. At this time, the extrusion platform 516 is inserted When the sample is placed in the placement groove 31, due to the thickness of the sample, the pressure exerted by the upper press seat 5 on the lower press seat 3 will overcome the elastic force of the spring 2 36 and slide downward along the guide rod 34, so that the relative position of the cavity 33 and the guide rod 34 changes. The lower press seat 3 moves downward adaptively with the thickness of the sample, and in the process of the guide plate 410 entering the rotating groove 42 from the lifting groove 41, the closing cylinder 55 at the bottom end of the upper press seat 5 moves downward synchronously and abuts against the top of the guide groove 21 at the bottom end of the outer barrel 2. Since the inner diameter of the closing cylinder 55 is the same as the outer diameter of the support cylinder 37, and rubber sealing rings are embedded in the bottom and inside, the drainage groove 38 at the side end of the support cylinder 37 is blocked to prevent the liquid from flowing out at this stage. Subsequently, clean water is added to the outer barrel 2, so that the clean water level rises and does not cover the upper press seat 5 in the rotating groove 42, and the clean water flows into the placement groove 31 through the flow groove 32 on the inner wall of the placement groove 31 at the top of the lower press seat 3, and contacts the textile sample placed therein. As the upper press seat 5 continues to rotate, the squeezing platform 516 at its bottom end cooperates with the placement groove 31 of the lower press seat 3 to squeeze the textile sample. During the squeezing process, the ball 515 at the bottom end of the medicine box 57 abuts against the surface of the sample. Due to the reaction force generated by the squeezing of the sample, the ball 515 moves upward. At the same time, the rotation of the upper press seat 5 drives the ball 515 to rotate under the action of the friction with the sample, thereby bringing the medicine in the medicine storage cavity 58 out with the rotation of the ball 515 and evenly smearing it on the textile sample. Under the dual action of rotation and squeezing, the dye in the sample is gradually precipitated and dissolved in the clean water. During the rotation of the upper pressure seat 5, the mounting shaft 411 at the bottom end of the guide plate 410 moves upward, and the mounting shaft 411 drives the sleeve 412 and the fan blade 413 to rotate around the mounting shaft 411 under the thrust of the water flow, thereby stirring the water flow in the outer barrel 2, so that the precipitated dye is fully mixed with the clean water to ensure the dye extraction effect. When the dye precipitation is completed, the control motor 47 drives the rotating rod 48 to rotate in the opposite direction, and the upper pressure seat 5 is reversed. At this time, the guide plate 410 abuts against the arc surface of one side of the top block 45 in the rotating groove 42. Due to the contact between the bottom end of the lifting groove 41 and the top block 45 This side arc surface is on the same spiral trajectory. Under the guidance of the arc surface of the top block 45, the guide plate 410 rotates in the opposite direction and returns to the lifting groove 41. At the same time, under the reverse action, the upper press seat 5 moves upward along the axis of the rotating rod 48, driving the sealing cylinder 55 to move upward synchronously, exposing the drainage groove 38. The liquid in the outer barrel 2 is guided by the inverted conical bottom surface of the guide groove 21 and converges to the lowest end of the guide groove 21. It passes through the drainage groove 38 at the side end of the support cylinder 37 and is finally discharged from the discharge pipe 22 connected to the guide groove 21 and located directly below the support cylinder 37, completing the entire dye extraction operation. The W-shaped placement groove 31 of the lower pressure seat 3 cooperates with the circulation groove 32, and the inclined surface is used to guide the liquid to accelerate the flow, avoid the retention of medicine, and improve the efficiency of dye precipitation. The inverted convex cavity 33, the guide rod 34 and the spring 2 36 form an adaptive structure, which can automatically adjust the height of the lower pressure seat 3 according to the thickness of the sample without manual intervention to prevent excessive squeezing and damage to the sample. The conical connecting block 35 cooperates with the drainage groove 38 and the guide groove 21 to form a smooth drainage channel to ensure the rapid collection of the dye solution. The overall mechanical linkage reduces manual operation and improves the degree of detection automation. The spiral lifting groove 41 of the driving part 4 and the guide plate 410 are used to convert the rotational motion of the motor 47 into the spiral lifting of the upper pressure seat 5 to achieve precise displacement control and simplify the mechanical structure. The top block 45 and the spring 1 44 automatically switch operation. The moving trajectory ensures horizontal rotation during extrusion and returns along the original trajectory during reset to avoid interference. The fan blades 413 at the bottom of the guide plate 410 automatically stir the liquid with the water flow, and can promote dye mixing without additional power. Combined with the forward and reverse control of the motor 47, the full process of "extrusion-stirring-discharge" is automated. The extrusion platform 516 of the upper pressure seat 5 is adapted to the W-shaped placement groove 31, and the sample is evenly rubbed during rotation to ensure that the dye is fully analyzed. The medicine box 57 and the ball 515 are linked to each other to release the medicine on demand and apply it evenly to avoid waste and manual intervention. The closing cylinder 55 automatically blocks or opens the drainage groove 38 through the rubber sealing ring, controls the timing of liquid discharge, ensures a stable environment during the immersion stage, and cooperates with the quick-loading and unloading medicine box 57 structure to enhance the compatibility of the device with different samples and the convenience of operation.
