Description

Technical Field

[0001] This invention belongs to the field of textile dyeing technology, specifically a mechanical device for synchronously adjusting the temperature of fabric dyeing and finishing. Background Technology

[0002] Fabric dyeing and finishing temperature refers to the specific temperature range that the dye liquor or treatment medium needs to reach and maintain during the dyeing and finishing process of fabrics. Different dyes and fiber materials have different temperature requirements, and temperature directly affects the dye uptake rate, evenness, color fastness, and physical properties of fibers. For example, reactive dyeing is usually carried out at 60℃ to 80℃, while disperse dyeing of polyester requires high temperature and high pressure conditions of around 130℃. Synchronous adjustment of fabric dyeing and finishing temperature is to monitor the dye liquor temperature in real time and automatically adjust the heating power according to process requirements, so that the dye liquor temperature changes according to a preset curve (heating, holding, cooling), ensuring dyeing uniformity and color fastness, while saving energy.

[0003] A prior art document (CN217127747U) discloses a dyeing box for silk dyeing with easily adjustable temperature. The box includes a body with four rectangular support pillars fixed to its bottom outer wall. Openings are provided on both sides of the outer wall of the box. Two symmetrically distributed conveying rollers are connected to the inner walls of the two openings via bearings. Two symmetrically distributed heating lamps are fixed to the inner wall of the box. A dyeing assembly is installed inside the box. This invention utilizes a motor to drive multiple stirring rods on a stirring shaft, ensuring thorough mixing of dye and water and preventing dye from settling. A heating grid heats the water in the annular heating chamber, and the heat is radiated to the dyeing vat to heat the dyeing solution, preventing dye granulation. A temperature sensor detects the temperature and displays the data on a display. A microprocessor can be used to adjust the power of the heating grid, thus achieving easy temperature control. While the aforementioned patents achieve monitoring and electronic control of dye liquor temperature through heating grids, temperature sensors, and microprocessors, they cannot effectively solve the problems of easy failure, slow response, and high energy consumption caused by independent control of heating and stirring in high-temperature and high-humidity dyeing environments. Traditional electronic temperature control devices rely on temperature sensors and microprocessors. In the long-term high-temperature, high-humidity, and corrosive gas environment of dyeing workshops, electronic components are prone to moisture aging and signal drift, leading to temperature control failure or temperature overshoot. At the same time, the PID regulation of the electronic control system has inherent response delay, making it difficult to achieve real-time proportional adjustment of heating power and temperature deviation. Switch heating is prone to temperature fluctuations, affecting dyeing uniformity. Summary of the Invention

[0004] The purpose of this invention is to provide a mechanical device for synchronously adjusting the temperature of fabric dyeing and finishing by mechanical proportional temperature control and heating and stirring linkage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mechanical device for synchronously regulating the temperature of fabric dyeing and finishing, comprising a dyeing tank, wherein a dyeing trough is disposed in the middle of the dyeing tank, an air inlet pipe is fixedly connected to one side of the dyeing tank, and an exhaust pipe is fixedly connected to the other side of the dyeing tank, and further comprising: An adaptive temperature control mechanism is located on the dyeing tank; An automatic stirring mechanism, which is connected to an adaptive temperature control mechanism; The adaptive temperature control mechanism includes a heating chamber located below the dyeing pool.

A stopper rod is slidably connected to the sleeve. A valve core is fixedly connected to the bottom of the stopper rod, and the valve core is in the shape of a disc.

[0006] Preferably, the adaptive temperature control mechanism further includes a temperature display fixed to the side wall of the thermal expansion sensing bulb, the temperature display being fixed to the dyeing bath, and the temperature display facing outward through a viewing slot.

[0007] Preferably, the heating cavity is connected to the air inlet pipe and the air outlet pipe on both sides, respectively. The heating cavity is concave and wraps around the outside of the dyeing tank. The outer wall of the valve core is slidably connected to a sliding groove box, and the lower side of the sliding groove box is fixedly connected to the air inlet pipe.

[0008] Preferably, the outer wall of the valve core abuts against a compression rod, the upper side of the compression rod is slidably connected to the lower side of the slide box, and a fixing ring is fixedly connected to the lower side of the compression rod.

[0009] Preferably, the extrusion rod is elastically connected to the chute box via a fixing ring, and the outer wall of the extrusion rod abuts against a main switch, which is fixed to the side wall of the dyeing pool.

[0010] Preferably, the automatic stirring mechanism includes a push rod that slides through the side wall of the trough box, a fixing plate that is slidably connected to the outer wall of the push rod, the side wall of the fixing plate being fixed to the dyeing tank, a drive motor being fixed to the side wall of the dyeing tank via a bracket, and a first locking block being fixed to the output end of the drive motor.

[0011] Preferably, a rotating shaft is rotatably connected to both sides of the dyeing tank, and several stirring blades are fixedly attached to the outer wall of the rotating shaft at equal intervals. A partition net is fixedly attached to both sides of the bottom of the dyeing tank, and the partition net covers the outside of the stirring blades.

[0012] Preferably, each of the two rotating shafts is fixedly connected to a pulley at its end, and the outer walls of the two pulleys are provided with a connecting belt. A protective shell is provided outside the connecting belt, and the side wall of the protective shell is fixedly connected to the dyeing pool.

[0013] Preferably, one end of the rotating shaft is slidably connected to a sliding sleeve via a convex strip, the inner side of the sliding sleeve is elastically connected to the outer wall of the dyeing pool, and a second locking block is fixedly connected to the outer side of the sliding sleeve, the locking teeth of the second locking block being compatible with the locking teeth of the first locking block.

[0014] Preferably, the top of the fixed plate has an opening groove, the bottom of the sliding sleeve is fixedly connected to a triangular plate, the triangular plate is slidably connected in the opening groove, and the hypotenuse of the triangular plate abuts against the push rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This invention utilizes the combination of structures such as a thermal expansion sensing bulb, capillary tube, sleeve, stopper rod, valve core and sliding box to drive the thermal expansion and contraction of the sensing liquid by the temperature change of the dye liquor itself. The pressure transmission through the capillary tube causes the stopper rod to drive the valve core to move linearly. The opening of the valve core is proportional to the temperature deviation. The lower the temperature, the more the valve core rises and the greater the flow rate of the heating medium. The closer the temperature is to the set value, the smaller the valve core opening. This realizes the proportional adjustment of heating power and temperature error. It can improve the temperature control accuracy without any temperature sensor and electronic control system, effectively avoiding the problem of easy failure of electronic components in high temperature and high humidity environment. At the same time, it eliminates the response lag of electronic control adjustment and improves the dyeing uniformity.

[0016] (2) By setting up a combination of structures such as valve core, extrusion rod, main switch, push rod, triangular plate, sliding sleeve, second locking block, first locking block, rotating shaft and stirring blade, the linear displacement of the valve core is used as a composite control signal for heating start and stop and stirring transmission. When the valve core moves upward, the extrusion rod returns to its original position to open the main switch. At the same time, the arc-shaped end face of the valve core pushes the push rod, which drives the sliding sleeve to move axially through the inclined surface of the triangular plate, so that the second locking block engages with the rotating first locking block and the stirring is started automatically. When the valve core moves downward, the extrusion rod presses down to close the main switch, the push rod returns to its original position to disengage the second locking block, and the stirring stops automatically. This realizes a pure mechanical linkage of automatic engagement of heating stirring and automatic disengagement of heat preservation stirring. Compared with independent continuous stirring, it effectively saves energy consumption and uses a mesh to effectively prevent the cloth from tangling. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 11 As shown, the present invention provides a mechanical device for synchronously regulating the dyeing and finishing temperature of fabrics, including a dyeing tank 100, a dyeing trough 200 disposed in the middle of the dyeing tank 100, an air inlet pipe 300 fixedly connected to one side of the dyeing tank 100, and an exhaust pipe 600 fixedly connected to the other side of the dyeing tank 100, and further including: An adaptive temperature control mechanism 400 is located on the staining tank 100; Automatic stirring mechanism 500, which is connected to adaptive temperature control mechanism 400; The adaptive temperature control mechanism 400 includes a heating chamber 430 located below the dyeing pool 100. A thermal expansion sensing bulb 4110 is fixedly connected to the top of the heating chamber 430. The thermal expansion sensing bulb 4110 is fixedly connected to a sleeve 420 through a capillary tube 4100. A stopper rod 460 is slidably connected to the sleeve 420. A valve core 470 is fixedly connected to the bottom of the stopper rod 460 and is disc-shaped.

[0021] The above scheme is adopted: the dyeing tank 200 located in the middle of the dyeing tank 100 is used to hold the fabric and dye liquor, and the air inlet pipe 300 fixed on one side of the dyeing tank 100 and the exhaust pipe 600 fixed on the other side are respectively connected to the input and output of the heating medium. An adaptive temperature control mechanism 400 located on the dyeing tank 100 is connected to an automatic stirring mechanism 500. A thermal expansion temperature sensor 4110 is fixedly attached to the top of the heating chamber 430 located on the lower side of the dyeing tank 100. The thermal expansion temperature sensor 4110 is immersed in the dye liquor to sense temperature changes. The thermal expansion temperature sensor 4110 is fixedly connected to a sleeve 420 through a capillary tube 4100. A stopper rod 460 is slidably connected inside the sleeve 420. A disc-shaped valve core 470 is fixedly attached to the bottom of the stopper rod 460. When the temperature of the dye liquor changes, the change in the volume of the temperature-sensing liquid in the thermal expansion temperature sensor 4110 is transmitted to the sleeve 420 through the capillary tube 4100, driving the stopper rod 460 to move the valve core 470 in the channel between the air inlet pipe 300 and the heating chamber 430 to adjust the flow rate of the heating medium. At the same time, the displacement of the valve core 470 triggers the start and stop of the automatic stirring mechanism 500, thereby realizing the coordinated operation of temperature sensing, proportional adjustment and stirring linkage.

[0022] like Figure 2 , Figures 7 to 11 As shown, the adaptive temperature control mechanism 400 also includes a temperature display 490 fixed to the side wall of the thermal expansion sensing bulb 4110. The temperature display 490 is fixed to the dyeing tank 100 and faces outward through a viewing slot. The heating chamber 430 is connected to the air inlet pipe 300 and the exhaust pipe 600 on both sides, respectively. The heating chamber 430 is concave and wraps around the outside of the dyeing tank 200. The outer wall of the valve core 470 is slidably connected to a sliding groove box 41. 0. The lower side of the slide box 410 is fixedly connected to the air inlet pipe 300; the outer wall of the valve core 470 abuts against the extrusion rod 450, the upper side of the extrusion rod 450 is slidably connected to the lower side of the slide box 410, and the lower side of the extrusion rod 450 is fixedly connected to the fixing ring 480; the extrusion rod 450 is elastically connected to the slide box 410 through the fixing ring 480, and the outer wall of the extrusion rod 450 abuts against the main switch 440, which is fixedly connected to the side wall of the dyeing pool 100.

[0023] The above scheme is as follows: When the temperature inside the dyeing tank 200 decreases, the temperature-sensing liquid inside the thermal expansion sensing bulb 4110 contracts, the pressure inside the sleeve 420 decreases, and when the stopper rod 460 drives the valve core 470 to move upward, the downward pushing force of the valve core 470 on the extrusion rod 450 gradually decreases. The extrusion rod 450 moves upward under the upward pulling force generated by the elastic connection between the fixing ring 480 and the slide box 410. As the extrusion rod 450 moves upward, its resistance to the main switch 440 gradually decreases until it is released. The main switch 440 automatically opens under the action of the internal reset spring, and the channel between the air inlet pipe 300 and the heating chamber 430 is opened, allowing steam to enter the heating chamber 430 to heat the dyeing tank 200. When the valve core 470 rises to a certain height, the extrusion rod 450 is completely released from the pressure on the main switch 440, and the main switch 440 is fully opened, confirming that the heating state has been entered. The minute displacement of the valve core 470 is amplified into a clear opening and closing action of the main switch 440, ensuring the reliability and responsiveness of heating start-up and shutdown.

[0024] like Figures 2 to 11 As shown, the automatic stirring mechanism 500 includes a push rod 5100 that slides through the side wall of the trough box 410. A fixing plate 5110 is slidably connected to the outer wall of the push rod 5100. The side wall of the fixing plate 5110 is fixed to the dyeing tank 100. A drive motor 510 is fixed to the side wall of the dyeing tank 100 via a bracket. A first locking block 580 is fixed to the output end of the drive motor 510. Rotating shafts 530 are rotatably connected to both sides of the dyeing tank 100. Several stirring blades 540 are equidistantly fixed to the outer wall of the rotating shafts 530. Partition nets 520 are fixed to both sides of the bottom of the dyeing tank 200. The partition nets 520 cover the outside of the stirring blades 540. Pulleys 570 are fixed to the ends of a pair of rotating shafts 530. A connecting belt 560 is provided on the outer wall, and a protective shell 550 is provided on the outside of the connecting belt 560. The side wall of the protective shell 550 is fixed to the dyeing tank 100. The end of one side rotating shaft 530 is slidably connected to a sliding sleeve 5120 through a protrusion 5150. The inner side of the sliding sleeve 5120 is elastically connected to the outer wall of the dyeing tank 100. A second locking block 590 is fixedly connected to the outer side of the sliding sleeve 5120. The locking teeth of the second locking block 590 are compatible with the locking teeth of the first locking block 580. An opening slot 5130 is opened on the top of the fixing plate 5110. A triangular plate 5140 is fixedly connected to the bottom of the sliding sleeve 5120. The triangular plate 5140 is slidably connected in the opening slot 5130. The hypotenuse of the triangular plate 5140 abuts against the push rod 5100.

[0025] The above scheme employs the following method: Since the valve core 470 is disc-shaped, its arc-shaped upper surface gradually contacts the end of the push rod 5100 during its ascent, pushing the push rod 5100 to move horizontally. This arc-shaped surface design ensures a smooth increasing relationship between the upward stroke of the valve core 470 and the horizontal displacement of the push rod 5100, avoiding impact and jamming. A fixing plate 5110, fixed to the dyeing tank 100, is slidably connected to the outer wall of the push rod 5100, providing precise linear guidance for the push rod 5100. The push rod 5100 moves along the fixing plate 5110 towards the second locking block 590, with its end abutting against the inclined surface of the triangular plate 5140. The triangular plate 5140 is fixed to the bottom of the sliding sleeve 5120 and slidably connected within the opening slot 5130 at the top of the fixing plate 5110. Due to the limiting effect of the opening slot 5130, the triangular plate 5140 can only move along the axial direction of the rotating shaft 530 and cannot rotate. This limiting design ensures the uniqueness of the movement direction and the stability of the transmission. The push rod 5100 pushes the inclined surface of the triangular plate 5140, decomposing the horizontal thrust into a component force along the axial direction of the rotating shaft 530. This causes the triangular plate 5140 to drive the sliding sleeve 5120 to slide axially outward along the protrusion 5150 at the end of the rotating shaft 530. The second locking block 590 fixed to the outside of the sliding sleeve 5120 moves outward accordingly. The protrusion 5150 cooperates with the keyway on the inner wall of the sliding sleeve 5120, ensuring that the sliding sleeve 5120 can both slide axially and transmit torque, resulting in a compact and reliable structure. At this time, the drive motor 510 fixed to the side wall support of the dyeing pool 100 is in a continuous operating state, and the first locking block 580 fixed to its output end continues to rotate. When the second locking block 590 moves outward and engages with the locking teeth of the first locking block 580, the first locking block 580 drives the second locking block 590, the sliding sleeve 5120, and the rotating shaft 530 to rotate synchronously. The pulley 570 at one end of the rotating shaft 530 drives the pulley 570 on the other side of the rotating shaft 530 through the connecting belt 560, so that the two rotating shafts 530 rotate synchronously, thereby driving the several stirring blades 540 fixed at equal intervals on the outer wall of the rotating shaft 530 to rotate and stir at the bottom of the dyeing tank 200.

[0026] Working principle and usage process of this invention: Initially, the dyeing tank 200 in the middle of the dyeing pool 100 contains the fabric to be dyed and the dye liquor. The main switch 440 is in the closed position. At this time, no steam enters the air inlet pipe 300, the heating chamber 430 is not heated, and the temperature in the dyeing tank 200 is in the natural cooling and decreasing stage. The thermal expansion temperature sensor 4110 is fixed to the top of the heating chamber 430 and is filled with a temperature-sensing liquid, such as kerosene or xylene. As the temperature in the dyeing tank 200 gradually decreases, the volume of the temperature-sensing liquid in the thermal expansion temperature sensor 4110 contracts. The liquid flows back from the sleeve 420 to the thermal expansion temperature sensor 4110 through the capillary tube 4100. The pressure in the sleeve 420 decreases, causing the stopper rod 460, which is slidably connected in the sleeve 420, to move upward under the action of external atmospheric pressure or spring force. The valve core 470, which is fixed to the bottom of the stopper rod 460, slides upward in the slide box 410, gradually opening the channel between the air inlet pipe 300 and the heating chamber 430. At this time, steam enters the sump box 410 through the air inlet pipe 300, and then enters the heating chamber 430. The heating chamber 430 is concave and surrounds the outside of the dyeing tank 200. After flowing along the heating chamber 430, the steam is discharged from the exhaust pipe 600, uniformly heating the dye liquor in the dyeing tank 200. Since the opening degree of the valve core 470 is proportional to the temperature deviation, the lower the temperature, the more the valve core 470 rises and the larger the opening degree, resulting in greater heating power. The closer the temperature is to the set value, the smaller the opening degree of the valve core 470, realizing proportional regulation of heating power and effectively avoiding the temperature overshoot phenomenon of traditional on / off temperature control. The temperature control accuracy can reach within ±1.5℃. At the same time, the temperature display 490 is fixed to the side wall of the thermal expansion sensing bulb 4110 and faces outward through the viewing slot, displaying the dye liquor temperature in real time, which is convenient for operators to monitor intuitively. Secondly, when the valve core 470 is in its lowest position, the temperature inside the dyeing tank 200 is at a relatively high level and heating is not required. At this time, the valve core 470 pushes the extrusion rod 450 downward. The extrusion rod 450 overcomes the elastic force and moves downward. The outer wall of the extrusion rod 450 abuts against the main switch 440 and applies pressure to the main switch 440 to keep it closed. No steam enters the air inlet pipe 300, and the heating chamber 430 is not heated. When the temperature inside the dyeing tank 200 decreases, the temperature-sensing liquid inside the thermal expansion sensing bulb 4110 contracts, the pressure inside the sleeve 420 decreases, and when the stopper rod 460 drives the valve core 470 to move upward, the downward pushing force of the valve core 470 on the extrusion rod 450 gradually decreases. The extrusion rod 450 moves upward under the upward pulling force generated by the elastic connection between the fixing ring 480 and the slide box 410. As the extrusion rod 450 moves upward, its pressure on the main switch 440 gradually decreases until it is released. The main switch 440 automatically opens under the action of the internal reset spring, opening the channel between the air inlet pipe 300 and the heating chamber 430, allowing steam to enter the heating chamber 430 to heat the dyeing tank 200. When the valve core 470 rises to a certain height, i.e., when the temperature drops to the threshold required for heating, the extrusion rod 450 completely releases its pressure on the main switch 440, and the main switch 440 fully opens, confirming the entry into the heating state. At the same time, the upward movement of the valve core 470 synchronously drives the automatic stirring mechanism 500: the push rod 5100, which slides through the side wall of the trough box 410, is driven by the upward movement of the valve core 470. Specifically, the arc-shaped upper end surface of the disc-shaped valve core 470 pushes the push rod 5100 to move horizontally. The outer wall of the push rod 5100 is slidably connected to a fixing plate 5110 fixed to the dyeing tank 100. The push rod 5100 moves along the fixing plate 5110 toward the second locking block 590. The end of the push rod 5100 abuts against the inclined surface of the triangular plate 5140. The triangular plate 5140 is fixed to the bottom of the sliding sleeve 5120 and slidably connected within the opening slot 5130 at the top of the fixing plate 5110. Due to the limiting effect of the opening slot 5130, the triangular plate 5140 can only move along the axial direction of the rotating shaft 530 and cannot rotate. The push rod 5100 pushes the inclined surface of the triangular plate 5140, causing the triangular plate 5140 to drive the sliding sleeve 5120 to slide axially outward along the protrusion 5150 at the end of the rotating shaft 530. The second locking block 590 fixed to the outside of the sliding sleeve 5120 moves outward accordingly. At this time, the drive motor 510, fixed to the side wall support of the dyeing tank 100, is in continuous operation, and the first locking block 580 fixed to its output end continues to rotate. When the second locking block 590 moves outward to engage with the locking teeth of the first locking block 580, the first locking block 580 drives the second locking block 590, the sliding sleeve 5120, and the rotating shaft 530 to rotate synchronously. The pulley 570 at the end of one rotating shaft 530 drives the pulley 570 on the other rotating shaft 530 through the connecting belt 560, so that the two rotating shafts 530 rotate synchronously, thereby driving the several stirring blades 540 fixed at equal intervals on the outer wall of the rotating shaft 530 to rotate and stir at the bottom of the dyeing tank 200.A mesh screen 520 is installed outside the stirring blade 540, allowing the dye liquor to pass through while effectively preventing the fabric from becoming entangled in the stirring blade 540 during the dyeing process. This design enables automatic activation of stirring when the temperature drops, promoting uniform mixing and heat exchange of the dye liquor, accelerating the heating process, and effectively saving energy compared to continuous stirring. Secondly, as the steam continues to heat the dye bath 200, the temperature of the dye liquor gradually rises. When the temperature reaches the set value, the temperature-sensing liquid in the thermal expansion sensing bulb 4110 expands and is pressed into the sleeve 420 through the capillary tube 4100, pushing the stopper rod 460 downward. The valve core 470 then gradually closes downward, reducing the steam flow. When the temperature reaches the target insulation range, the valve core 470 closes to a small opening, maintaining only the small flow of steam required for insulation. As the valve core 470 moves downward, the squeeze rod 450 returns to its original position under the action of elastic restoring force, releasing the trigger on the main switch 440. At the same time, the push rod 5100 loses its thrust and returns to its original position. The end of the push rod 5100 disengages from the inclined surface of the triangular plate 5140, and the sliding sleeve 5120 returns axially inward under the action of its inner spring. The second locking block 590 disengages from the first locking block 580, the rotating shaft 530 stops rotating, and the stirring blade 540 stops stirring. This automatic stop-stirring mechanism avoids excessive stirring during the heat preservation stage, which can generate foam and affect dyeing quality, while also saving energy. Through the linear linkage between the valve core opening at 470 degrees and the temperature, the system can automatically maintain the dye liquor temperature within a small range around the set value without manual intervention. Finally, throughout the dyeing process, the aforementioned linkage cycle can be automatically executed repeatedly according to changes in the dye liquor temperature. Since the entire system requires no temperature sensors, microprocessors, or other electronic components, relying entirely on the thermal expansion and contraction of the liquid in the thermal expansion sensing bulb 4110, the pressure transmission through the capillary tube 4100, the displacement of the stopper rod 460 and valve core 470, and the inclined plane transmission between the push rod 5100 and the triangular plate 5140, it exhibits higher reliability and a longer service life in high-temperature and high-humidity dyeing environments, effectively avoiding the problems of electronic components being susceptible to moisture, aging, and failure. Simultaneously, the temperature display 490 directly displays the expansion amount of the thermal expansion sensing bulb 4110 via a mechanical dial, allowing temperature readings without a power source. Even in the event of a power outage, operators can accurately monitor the dye liquor temperature. This fabric dyeing and finishing temperature synchronization adjustment mechanism organically integrates temperature sensing, proportional adjustment, and stirring linkage into a purely mechanical linkage system. It achieves proportional adjustment of heating power and temperature deviation, as well as automatic matching of stirring and heating conditions, effectively improving the uniformity, consistency, and energy efficiency of dyeing.
