Description

Technical Field

[0001] This utility model relates to the field of textile dyeing and finishing equipment technology, and in particular to a dye cup filling and exhaust device. Background Technology

[0002] Supercritical carbon dioxide anhydrous dyeing is an innovative textile dyeing technology. Its core principle is to use supercritical carbon dioxide to replace water in traditional dyeing processes as the medium for dissolving and transferring dyes, achieving pollution-free dyeing of fiber fabrics. This technology fundamentally solves the industry pain points of traditional water-based dyeing—high water consumption, high pollution, and high energy consumption—and is one of the key technologies for the textile industry's transformation towards green and sustainable development.

[0003] Before mass production, small-scale dyeing and sampling are required to determine the dyeing process and effect. The dye cup is a high-pressure container used to hold the sample and fill it with carbon dioxide for dyeing. It consists of a cup body, a cup lid, and components such as inflation and deflation ports. Traditional dye cup inflation and deflation operations require manual connection of pipes and opening of valves, which is not only cumbersome and time-consuming, but also increases the workload of operators. Moreover, since the dye cup is a high-pressure container with high internal pressure, manual operation is risky and the safety of the operation is low.

[0004] Therefore, there is an urgent need for a dye cup filling and venting device to solve the above problems. Utility Model Content

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0048] Traditional dye cup filling and venting operations require manual connection of pipes and opening of valves, which is not only cumbersome and time-consuming, but also increases the workload of operators. Moreover, since dye cups are high-pressure containers with high internal pressure, manual operation is risky and has low safety.

[0049] Therefore, in order to make the operation of filling and venting the dye cup more convenient, reduce the workload of operators, reduce the risk of manual operation, and improve the safety of operation, this embodiment provides a dye cup filling and venting device for filling and venting the dye cup, wherein the dye cup is provided with an air inlet and an air outlet.

[0050] like Figures 1 to 10 As shown, the dye cup inflation and deflation device includes a fixed plate assembly 1, an inflation assembly 2, and an deflation assembly 3. The fixed plate assembly 1 includes a mounting back plate 11 and guide plates 12. The dye cup 100 is detachably connected to the mounting back plate 11. Two guide plates 12 are spaced apart and connected to the mounting back plate 11 on both the side of the dye cup 100 with an inflation port and the side of the dye cup 100 with an deflation port. The inflation assembly 2 includes an inflation head 21 and an inflation drive module 22. The inflation head 21 is slidably disposed between the two guide plates 12 located on the side of the inflation port. The inflation drive module 22 is connected to the mounting back plate 11 and is used to drive the inflation head 21 to engage or disengage from the inflation port. The deflation assembly 3 includes an deflation head 31 and an deflation drive module 32. The deflation head 31 is slidably disposed between the two guide plates 12 located on the side of the deflation port. The deflation drive module 32 is connected to the mounting back plate 11 and is used to drive the deflation head 31 to engage or disengage from the deflation port.

[0051] By installing an inflation head 21 driven by an inflation drive module 22 and an exhaust head 31 driven by an exhaust drive module 32 on the mounting back plate 11 of the fixed dye cup 100, the inflation and exhaust operations of the dye cup 100 can be automatically performed by simply controlling the inflation head 21 to align with or detach from the inflation port of the dye cup 100 via the inflation drive module 22, and controlling the exhaust head 31 to align with or detach from the exhaust port of the dye cup 100 via the exhaust drive module 32. This allows operators to focus solely on fixing the dye cup 100, making the operation convenient, time-saving, and labor-saving. It not only reduces the workload of operators but also avoids manual operation of potentially dangerous inflation and exhaust operations, thus improving operational safety. Furthermore, by installing a guide plate 12 on the mounting back plate 11, the accuracy of the movement paths of the inflation head 21 and the exhaust head 31 is ensured, guaranteeing that the inflation head 21 and the exhaust head 31 can accurately align with the dye cup 100.

[0052] In this embodiment, as Figure 1 , Figure 4As shown, both the inflation head 21 and the deflation head 31 are provided with air pipe connectors on the side facing the mounting back plate 11. The mounting back plate 11 is provided with a clearance groove 111 that is the same as the movement trajectory of the air pipe connector, so that the air pipes of the inflation device and the deflation device can pass through the clearance groove 111 and connect to the air pipe connector.

[0053] In this embodiment, the inflation component 2 is connected to the inflation device to perform inflation operations, and the deflation component 3 is connected to the deflation device to perform deflation operations. In this one-to-one mode, inflation or deflation operations can be performed directly without adjusting the device, making the inflation and deflation operations highly efficient. However, considering the manufacturing cost, since the inflation component 2 and the deflation component 3 have the same structure, in other embodiments, only one of them can be set up. For example, only the inflation component 2 can be set up, so that during inflation operations, the inflation device is connected to the inflation component 2, and during deflation operations, the inflation device is removed and the deflation device is connected to the inflation component 2. Compared with this embodiment, this mode is more cumbersome to operate, but the cost is lower.

[0054] Optionally, such as Figures 1 to 3 As shown, the dyeing cup 100 includes a cup body 101, and the fixing plate group 1 includes two fixing plates 13. One of the two fixing plates 13 is connected to the side of the mounting back plate 11 near the air inlet, and the other of the two fixing plates 13 is connected to the side of the mounting back plate 11 near the exhaust outlet. The fixing plate 13 is provided with a fixing groove 131, and the cup body 101 is snapped into the fixing groove 131.

[0055] By providing a fixing plate 13 with a fixing groove 131 on the mounting back plate 11, the dye cup 100 can be easily fixed on the mounting back plate 11 by inserting the cup body 101 of the dye cup 100 into the fixing groove 131.

[0056] In this embodiment, the fixing groove 131 is adapted to the shape of the cup body 101 of the dye cup 100. The cup body 101 of the dye cup 100 is cylindrical, so the fixing groove 131 is arc-shaped, thereby allowing the dye cup 100 to fit better with the fixing plate 13. Furthermore, after the cup body 101 of the dye cup 100 is inserted into the fixing groove 131, a gap of 0.1mm to 0.5mm is left between the dye cup 100 and the fixing plate 13. This allows for easy placement and removal of the dye cup 100, and also allows the dye cup 100 to move appropriately within the gap range to adjust its position.

[0057] Optionally, such as Figures 1 to 3As shown, the fixing plate assembly 1 also includes rolling elements 14, with rolling elements 14 provided on both opposite inner walls of the fixing groove 131. By providing rolling elements 14 in the fixing groove 131, the resistance during the insertion of the dye cup 100 is reduced from static friction to rolling friction, making it easier to insert and remove the dye cup 100. Furthermore, the rolling elements 14 limit the movement of the dye cup 100, holding its outer edge in place to prevent it from tilting forward and thus avoiding it from coming out of the fixing groove 131 without external force. In this embodiment, the rolling element 14 is a ball-head plunger.

[0058] Optionally, such as Figures 1 to 3 As shown, the dyeing cup 100 also includes an inflation connector 102 and an exhaust connector 103. The inflation connector 102 is connected to the end of the cup body 101 with an inflation port to connect the inflation port and the inflation head 21. The exhaust connector 103 is connected to the end of the cup body 101 with an exhaust port to connect the exhaust port and the exhaust head 31. The fixing plate assembly 1 also includes two limiting plates 15. One of the two limiting plates 15 is connected to the side of the mounting back plate 11 near the inflation port, and the other of the two limiting plates 15 is connected to the side of the mounting back plate 11 near the exhaust port. The limiting plates 15 have limiting grooves 151, and the inflation connector 102 and the exhaust connector 103 are both engaged in the corresponding limiting grooves 151.

[0059] By setting an inflation connector 102 at the inflation port of the dye cup 100 and an exhaust connector 103 at the exhaust port of the dye cup 100, it is convenient for the inflation port to connect with the inflation head 21 and the exhaust port to connect with the exhaust head 31. Furthermore, by setting a limiting plate 15 to fix the inflation connector 102 and the exhaust connector 103, the accuracy of the positions of the inflation connector 102 and the exhaust connector 103 is ensured, so that the inflation connector 102 can be smoothly connected with the inflation head 21 and the exhaust connector 103 can be smoothly connected with the exhaust head 31.

[0060] Optionally, such as Figure 1 , Figure 2 As shown, the dye cup filling and venting device also includes a mounting position detection element 4, which is connected to the fixing plate 13. The mounting position detection element 4 is used to detect the position of the dye cup 100 in the fixing groove 131. By setting the mounting position detection element 4 on the fixing plate 13, when the dye cup 100 is docked with the fixing plate 13, if the mounting position detection element 4 detects the dye cup 100, it proves that the dye cup 100 is installed in place. If the mounting position detection element 4 does not detect the dye cup 100, the dye cup 100 is not installed in place, and the operator needs to check and install it again.

[0061] In this embodiment, the mounting position detection element 4 is a proximity switch, a sensor that can sense the approach of an object and output an electrical signal without direct contact with the object being detected. The core principle is to emit electromagnetic, optical, ultrasonic, or other signals. When an object enters its detection range, the signal changes due to the object's obstruction or induction. The internal circuit converts this change into a recognizable electrical signal, thereby detecting the object.

[0062] Optionally, such as Figure 5 , Figure 6 As shown, the inflation head 21 includes an inflation body 211 and a first slider 212. The first slider 212 is connected to the surface of the inflation body 211 facing the guide plate 12. The deflation head 31 includes a deflation body and a second slider. The second slider is connected to the surface of the deflation body facing the guide plate 12. A sliding groove 121 is provided on the guide plate 12. The first slider 212 and the second slider are slidably disposed in the corresponding sliding groove 121.

[0063] By setting a first slider 212 on the inflation body 211, setting a second slider on the exhaust body, and opening a sliding groove 121 on the guide plate 12, the sliding paths of the inflation head 21 and the exhaust head 31 are guided by the first slider 212 and the second slider sliding in the sliding groove 121, ensuring the accuracy of the sliding paths of the inflation head 21 and the exhaust head 31, and ensuring that the inflation head 21 can be smoothly connected to the inflation connector 102 of the dye cup 100, and the exhaust head 31 can be smoothly connected to the exhaust connector 103 of the dye cup 100.

[0064] Optionally, such as Figure 5 , Figure 6 As shown, the inflation head 21 also includes a first sealing member 214 and a first sealing plate 213. The inflation body 211 has a first mounting groove on the side facing the inflation port. The first sealing plate 213 is connected to the side of the inflation body 211 with the first mounting groove. The first sealing member 214 is disposed in the first mounting groove and sandwiched between the first sealing plate 213 and the inflation body 211.

[0065] By setting a first sealing plate 213 on one side of the inflation body 211 where the first mounting groove is opened, the first sealing member 214 is fixedly connected in the first mounting groove. When the inflation head 21 is connected to the inflation connector 102, the first sealing member 214 fills the gap between the inflation head 21 and the inflation connector 102 to achieve a seal and prevent air leakage when the inflation head 21 inflates the dye cup 100 through the inflation connector 102.

[0066] In this embodiment, the first sealing plate 213 has a first insertion hole for the insertion of the inflation connector 102. The inner wall of the first insertion hole has a beveled guide opening, and the inflation connector 102 has a rounded corner. The beveled guide opening and the rounded corner work together to allow the inflation connector 102 and the inflation head 21 to be successfully connected in a concentric state.

[0067] Optionally, the exhaust head 31 further includes a second seal and a second sealing plate. A second mounting groove is opened on the side of the exhaust body facing the exhaust port. The second sealing plate is connected to the side of the exhaust body where the second mounting groove is opened. The second seal is disposed in the second mounting groove and sandwiched between the second sealing plate and the exhaust body.

[0068] By setting a second sealing plate on one side of the exhaust body with a second mounting groove, the second sealing element is fixedly connected in the second mounting groove. When the exhaust head 31 is connected to the exhaust connector 103, the second sealing element fills the gap between the exhaust head 31 and the exhaust connector 103 to achieve a seal, thus preventing air leakage when the exhaust head 31 discharges gas from the dye cup 100 through the exhaust connector 103.

[0069] In this embodiment, the second sealing plate has a second insertion hole for inserting the exhaust connector 103. The inner wall of the second insertion hole has an angled guide opening, while the exhaust connector 103 has a rounded corner. The angled guide opening and the rounded corner work together to allow the exhaust connector 103 and the exhaust head 31 to smoothly dock in a concentric state. This allows the dye cup 100 to automatically adjust itself even if it is not concentric at the beginning of docking with the inflation head 21 or the exhaust head 31, resulting in more even force on the first sealing member 214 and the second sealing member, and higher sealing performance and durability.

[0070] Optionally, such as Figure 1 , Figure 2 , Figure 7 As shown, the fixed plate assembly 1 also includes two fixed brackets 16. One of the two fixed brackets 16 is connected to the side of the mounting back plate 11 near the inflation port, and the other of the two fixed brackets 16 is connected to the side of the mounting back plate 11 near the exhaust port. The inflation drive module 22 includes a first drive motor 221, a first screw jack 222, a first coupling 223, and an inflation connecting block 224. The first drive motor 221 is connected to the mounting back plate 11. The first coupling 223 is connected between the output end of the first drive motor 221 and the input end of the first screw jack 222. The first screw jack 222 is connected to the fixed bracket 16 located on the inflation port side. The output end of the first screw jack 222 is connected to the inflation connecting block 224. The inflation connecting block 224 is connected to the inflation head 21.

[0071] By using a lead screw drive to move the inflation head 21, the rotational motion of the first drive motor 221 can be stably converted into linear motion. The displacement of the inflation head 21 can be precisely controlled by a fixed pitch, and the movement of the inflation head 21 can be made smooth, thus improving the reliability of the inflation action.

[0072] Specifically, such as Figures 8 to 10 As shown, the first screw jack 222 includes a first transmission body 2221 and a first lifting screw 2222. The first transmission body 2221 is connected to the first drive motor 221 through a first coupling 223 and drives the first lifting screw 2222 to rotate. The first lifting screw 2222 includes a first connecting end, which extends out of the first transmission body 2221 and is connected to the inflation connecting block 224. The first connecting end is provided with a first limiting frustum 22221. The side of the inflation connecting block 224 connected to the inflation head 21 is provided with a first stepped limiting hole 2241. The first limiting frustum 22221 is rotatably engaged in the first stepped limiting hole 2241.

[0073] Since the first lifting screw 2222 converts rotational motion into linear lifting motion through threaded connection, the first lifting screw 2222 and the inflatable connecting block 224 need to be able to rotate relative to each other. By setting a first stepped limiting hole 2241 on the inflatable connecting block 224 and a first limiting frustum 22221 on the first lifting screw 2222, the first limiting frustum 22221 is fixed in the first stepped limiting hole 2241, so that the first lifting screw 2222 and the inflatable head 21 can be connected through the inflatable connecting block 224, while ensuring that the first lifting screw 2222 can rotate freely.

[0074] In this embodiment, the inflatable connecting block 224 is composed of two parts. When connecting and fitting, one half of the inflatable connecting block 224 is first connected to the inflatable head 21, then the first limiting frustum 22221 is docked with it, and finally the other half of the inflatable connecting block 224 is connected to the inflatable head 21 to complete the connection operation between the first lifting screw 2222 and the inflatable head 21.

[0075] Optionally, the exhaust drive module 32 includes a second drive motor, a second screw jack, a second coupling, and an exhaust connection block. The second drive motor is connected to the mounting back plate 11, the second coupling is connected between the output end of the second drive motor and the input end of the second screw jack, the second screw jack is connected to the fixed bracket 16 located on the exhaust port side, the output end of the second screw jack is connected to the exhaust connection block, and the exhaust connection block is connected to the exhaust head 31.

[0076] By using a lead screw drive to move the exhaust head 31, the rotational motion of the second drive motor can be stably converted into linear motion. The displacement of the exhaust head 31 can be precisely controlled by a fixed pitch, and the movement of the exhaust head 31 can be made smooth, thus improving the reliability of the exhaust action.

[0077] Specifically, the second screw jack includes a second transmission body and a second lifting screw. The second transmission body is connected to the second drive motor through a second coupling and drives the second lifting screw to rotate. The second lifting screw includes a second connecting end, which extends out of the second transmission body and is connected to the exhaust connecting block. The second connecting end is provided with a second limiting frustum. The exhaust connecting block is provided with a second stepped limiting hole on the side connected to the exhaust head 31. The second limiting frustum is rotatably engaged in the second stepped limiting hole.

[0078] Since the second lifting screw converts rotational motion into linear lifting motion through threaded connection, the second lifting screw and the exhaust connecting block need to be able to rotate relative to each other. By setting a second stepped limiting hole on the exhaust connecting block and a second limiting frustum on the second lifting screw, the second limiting frustum is fixed in the second stepped limiting hole, so that the second lifting screw and the exhaust head 31 can be connected through the exhaust connecting block, while ensuring that the second lifting screw can rotate freely.

[0079] In this embodiment, the exhaust connecting block is composed of two parts. When connecting and fitting, one half of the exhaust connecting block is first connected to the exhaust head 31, then the second limiting round platform is docked with it, and finally the other half of the exhaust connecting block is connected to the exhaust head 31 to complete the connection operation between the second lifting screw and the exhaust head 31.

[0080] The first drive motor 221 and the second drive motor are both servo motors, and they are equipped with encoders, so that the running time, running torque and running speed can be detected and programmed.

[0081] When connecting the inflation head 21 to the inflation connector 102 or the deflation head 31 to the deflation connector 103, there are two operating modes:

[0082] One method involves a servo motor driving the inflation head 21 or the deflation head 31 to a designated position. After the system automatically switches to torque mode and applies a torque command, it stops outputting when the actual torque reaches the set value. This occurs when the inflation head 21 has been connected to the inflation connector 102 or the deflation head 31 has been connected to the deflation connector 103 and can no longer move forward.

[0083] Another type is a servo motor that uses torque / speed / time composite control. It sets the target speed and torque threshold, continuously monitors the actual torque, and automatically stops when the set time is reached or the torque exceeds the limit. At this time, the inflation head 21 has been connected to the inflation connector 102 or the exhaust head 31 has been connected to the exhaust connector 103.

[0084] There are two operating modes when separating the inflation head 21 from the inflation connector 102 or the deflation head 31 from the deflation connector 103:

[0085] One method uses position or time control for the servo motor. During the disengagement process, it automatically stops when the set time or position is reached, indicating that the inflation head 21 has been completely disengaged from the inflation connector 102 or the exhaust head 31 has been completely disengaged from the exhaust connector 103.

[0086] Another method is to use sensors to determine whether the inflation head 21 has been completely disconnected from the inflation connector 102 or the exhaust head 31 has been completely disconnected from the exhaust connector 103 by detecting the positions of the first lifting screw 2222 and the second lifting screw.

[0087] Specifically, such as Figure 2 , Figure 10 As shown, the first lifting screw 2222 also includes a first detection end, which extends out of the first transmission body 2221 and is provided with a first detection frustum 22222. The dye cup filling and venting device also includes two first position detection elements 5. Both first position detection elements 5 are connected to the fixed bracket 16 located on the side of the filling port and are arranged in a staggered manner. The first position detection elements 5 are used to detect the position of the first detection frustum 22222.

[0088] By setting a first detection frustum 22222 at the first detection end of the first lifting screw 2222, and setting two first position detection elements 5 with different heights, one of the first position detection elements 5 is used to detect whether the inflation head 21 and the inflation connector 102 are fully connected, and the other first position detection element 5 is used to detect whether the inflation head 21 and the inflation connector 102 are completely separated.

[0089] In this embodiment, the first position detection element 5 is a proximity switch, a sensor that can sense the approach of an object and output an electrical signal without direct contact with the object being detected. The core principle is to emit electromagnetic, optical, ultrasonic, or other signals. When an object enters its detection range, the signal changes due to the object's obstruction or induction. The internal circuit converts this change into a recognizable electrical signal, thereby detecting the object.

[0090] Optionally, the second lifting screw also includes a second detection end, which extends out of the second transmission body and is provided with a second detection truncated cone. The dye cup filling and exhaust device also includes two second position detection elements 6, which are both connected to the fixed bracket 16 located on the exhaust port side and are arranged in a staggered manner. The second position detection elements 6 are used to detect the position of the second detection truncated cone.

[0091] By setting a second detection platform at the second detection end of the second lifting screw, and setting two staggered second position detection elements 6, one of the second position detection elements 6 is used to detect whether the exhaust head 31 and the exhaust connector 103 are fully connected, and the other second position detection element 6 is used to detect whether the exhaust head 31 and the exhaust connector 103 are completely separated.

[0092] In this embodiment, the second position detection element 6 is a proximity switch, a sensor that can sense the approach of an object and output an electrical signal without direct contact with the object being detected. Its core principle is to emit electromagnetic, optical, ultrasonic, or other signals. When an object enters its detection range, the signal changes due to the object's obstruction or induction. The internal circuit converts this change into a recognizable electrical signal, thereby detecting the object.

[0093] Optionally, such as Figure 4 As shown, each plate connected to the mounting back plate 11 is fixed by bolts. To better determine the connection position of each plate on the mounting back plate 11, the mounting back plate 11 is provided with a corresponding mounting groove 112 for each plate. This not only determines the installation position of each plate, but also, since each plate is subjected to bending stress during inflation and deflation operations, and this bending stress is transferred to the bolts, which can lead to bolt fatigue failure and unstable connection over time, the depth of each mounting groove 112 is set between 2mm and 5mm. This allows the overlapping area between each plate and each mounting groove 112 to share some of the bending stress, reduce the burden on the bolts, and improve service life.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
