Description

Technical Field

[0001] This invention relates to the field of textile printing and dyeing equipment technology, specifically to a dyeing and sampling machine with independent temperature control function. Background Technology

[0002] In the laboratory sampling stage of textile printing and dyeing, traditional dyeing sampling machines typically use overall heating or single temperature control to uniformly heat multiple dye cups. However, due to the different physical positions of each dye cup within the machine frame and variations in heat conduction efficiency, uneven temperature distribution of the dye liquor within the cups is easily caused, directly affecting the reproducibility and uniformity of the sampling results. Furthermore, the existing sampling machines often use direct placement or simple locking methods for installing and fixing the dye cups. When the drive mechanism shakes the sampling mechanism violently up and down, the cups are prone to loosening or falling off, or there are problems with inconvenient loading and unloading. In addition, the cluttered internal layout of traditional equipment and the lack of effective heat dissipation design make the electrical control system prone to overheating and damage, affecting the stability and lifespan of the entire machine. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a dyeing sample making machine with independent temperature control function.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A dyeing sample making machine with independent temperature control function includes a rectangular frame, a drive mechanism fixedly installed inside the lower part of the rectangular frame, a dyeing sample making mechanism mounted inside the upper part of the rectangular frame and driven by the drive mechanism to move up and down, a main control board fixedly installed on one side of the upper part of the rectangular frame, and a touch screen fixedly installed on the outside of the upper part of the rectangular frame and connected to the main control board; the dyeing sample making mechanism includes a support frame, a linkage rod fixedly installed below the support frame, an assembly wheel fixedly installed on one side of the lower end of the linkage rod, a cup holder fixedly installed on the support frame, and several dye cups fixedly installed on the cup holder; the cup holder includes a cup holder frame, fixedly mounted... The cup holder includes a first fixing plate with equidistant circular holes at the lower end of the cup holder frame; three double-ended studs fixedly installed at the bottom of the first fixing plate around the circular holes; a spring base fixedly installed by the three double-ended studs; a second fixing plate with equidistant circular holes at the upper end of the cup holder frame; a cup sleeve fixedly installed below the second fixing plate and coaxial with the circular holes; and J-shaped grooves on both sides of the cup sleeve for fixing the dye cup. The cup holder also includes several electric heating sleeves fixedly installed above the first fixing plate and coaxial with the circular holes; and several temperature sensors fixedly installed above the spring base for contacting the bottom of the dye cup.

[0006] The system consists of an electric heating jacket and a temperature sensor, which work together to heat and detect the temperature of a dye cup. The main control board is equipped with several temperature control modules, each of which works with the electric heating jacket and temperature sensor to control the temperature of different dye cups independently.

[0007] Preferably, the circular holes of the second fixing plate correspond one-to-one with the circular holes of the first fixing plate; the edge of the circular hole of the second fixing plate is provided with a clearance groove, which corresponds to the J-shaped grooves on both sides of the cup sleeve.

[0008] Preferably, the dye cup includes a dye cup body and clamping posts fixedly installed on both sides of the upper end of the dye cup body.

[0009] Preferably, the main control board is also provided with a terminal block, which is connected to several temperature control modules.

[0010] Preferably, the rectangular frame includes a frame body, a transverse partition plate fixedly installed in the center of the frame body, a vertical partition plate fixedly installed in the upper part of the frame body for fixing the main control board, two long guide rails located at the rear of the frame body and fixedly installed with the frame body and the vertical partition plate, long guide rail sliders mounted on the two long guide rails, two short guide rails located at the front of the frame body and fixedly installed with the frame body and the vertical partition plate, and short guide rail sliders mounted on the two short guide rails.

[0011] Furthermore, the rectangular rack also includes two cooling fans mounted on top of the rack body.

[0012] Furthermore, the two cooling fans are configured as an exhaust fan and an exhaust fan.

[0013] Preferably, the drive mechanism includes a base, a reducer fixedly mounted on one side above the base, a drive motor fixedly mounted to the reducer, a coupling fixedly mounted on the output end of the reducer, a flywheel mounted on the other side above the base with its rotating shaft fixedly mounted to the coupling, and an annular guide groove formed inside the flywheel.

[0014] Furthermore, the annular guide groove is eccentrically positioned, with one end close to the axis of the flywheel and the other end far from the axis of the flywheel.

[0015] This invention achieves independent and precise temperature control for each dyeing cup by equipping each cup with an independent electric heating jacket and temperature sensor, along with corresponding temperature control modules on the main control board. This overcomes the problem of uneven heating in traditional equipment, greatly improving the uniformity of dyeing and the flexibility of sample testing. Simultaneously, the use of an eccentric guide groove combined with upper and lower guide rails of varying lengths ensures stable and reliable shaking motion. Furthermore, the quick-locking structure of the avoidance groove, J-shaped groove, and spring base not only simplifies operation but also ensures the dyeing cups are securely fixed even under violent shaking. Combined with the modular spatial layout of the bottom drive, upper dyeing, and side control areas, as well as the optimized heat dissipation design of the top dual fans, this effectively improves the overall stability, ease of maintenance, and lifespan of electrical components.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention, but the embodiments are not intended to limit the present invention.

[0025] Example

[0026] See Figure 1-8A dyeing and sampling machine with independent temperature control function includes a rectangular frame 1, a drive mechanism 2 fixedly installed inside the lower part of the rectangular frame 1, a dyeing and sampling mechanism 3 installed inside the upper part of the rectangular frame 1 and driven to move up and down by the drive mechanism 2, a main control board 4 fixedly installed inside the upper part of the rectangular frame 1, and a touch screen 5 fixedly installed outside the upper part of the rectangular frame 1 and connected to the main control board 4.

[0027] The dyeing and sampling mechanism 3 includes a support frame 31, a linkage rod 32 fixedly installed below the support frame 31, an assembly wheel 33 fixedly installed on one side of the lower end of the linkage rod 32, a cup holder 34 fixedly installed on the support frame 31, and a plurality of dye cups 35 fixedly installed on the cup holder 34.

[0028] The cup holder 34 includes a cup holder frame 341, a first fixing plate 342 fixedly installed at the lower end of the cup holder frame 341 and having equidistant circular holes, three double-ended studs 343 fixedly installed at the bottom of the first fixing plate 342 and located around the circular holes, a spring base 344 fixedly installed by the three double-ended studs 343, a second fixing plate 345 fixedly installed at the upper end of the cup holder frame 341 and having equidistant circular holes, a cup sleeve 346 fixedly installed below the second fixing plate 345 and coaxial with the circular holes, and J-shaped grooves 347 on both sides of the cup sleeve 346 for fixing the dye cup 35. The cup holder 34 also includes a plurality of electric heating sleeves 348 fixedly installed above the first fixing plate 342 and coaxial with the circular holes, and a plurality of temperature sensors 349 fixedly installed above the spring base 344 for abutting the bottom of the dye cup 35.

[0029] Among them, an electric heating jacket 348 and a temperature sensor 349 are used together to heat and detect a dye cup 35; the main control board 4 is provided with several temperature control modules 42, each temperature control module 42 corresponding to the electric heating jacket 348 and temperature sensor 349 used for independent temperature control of different dye cups 35.

[0030] Specifically, the driving mechanism 2 drives the dyeing sample making mechanism 3 to move up and down and shake, simulating the dynamics of real dyeing. The core of this system lies in the addition of an electric heating sleeve 348 coaxial with the dye cup 35 and a temperature sensor 349 abutting the bottom in the cup holder 34, and combining them one-to-one with the temperature control module 42 on the main control board 4. This solves the problem of uneven heating between cups caused by the overall heating of traditional sample making machines, achieving precise independent temperature control and greatly improving the uniformity of dyeing samples and the reliability of experimental data.

[0031] The round holes of the second fixing plate 345 correspond one-to-one with the round holes of the first fixing plate 342, ensuring the verticality and concentricity of the dye cup during installation, so that the heating and temperature measuring elements at the bottom can be accurately aligned; the edge of the round hole of the second fixing plate 345 is provided with a relief groove 3451, which corresponds to the J-shaped grooves 347 on both sides of the cup sleeve 346, providing a physical channel for the insertion of the dye cup, so that the installation process does not require complicated alignment adjustment, and the operation is smoother and more convenient.

[0032] The dye cup 35 includes a dye cup body 351 and locking posts 352 fixedly installed on both sides of the upper end of the dye cup body 351, providing force points for subsequent locking with the J-shaped groove. This structure is simple and reliable, allowing the dye cup 35 to be quickly mechanically fixed through rotation, with uniform force distribution and less risk of damaging the cup structure.

[0033] When the dye cup 35 is installed, the dye cup body 351 is inserted into the round hole of the second fixing plate 345, the locking post 352 is aligned with the relief groove 3451 and enters the J-shaped groove 347 until the bottom of the dye cup body 351 presses against the spring base 344; the dye cup body 351 is rotated, the locking post 352 is locked into the J-shaped groove 347, and the spring base 344 bounces up and pushes the dye cup body 351 to lock the dye cup 35.

[0034] The main control board 4 is also provided with a terminal block 41, which is connected to several temperature control modules 42. This realizes the centralization, modularization and standardization of electrical wiring, greatly reduces the number of flying wires inside the cabinet, reduces the failure rate caused by poor wiring, and facilitates the quick replacement and maintenance of individual temperature control modules 42 in the future.

[0035] The rectangular frame 1 includes a frame body 11, a transverse partition 12 fixedly installed in the center of the frame body 11, a vertical partition 13 fixedly installed in the upper part of the frame body 11 for fixing the main control board 4, two long guide rails 14 located at the rear of the frame body 11 and fixedly installed with the frame body 11 and the vertical partition 13, long guide rail sliders 15 mounted on the two long guide rails 14, two short guide rails 16 located at the front of the frame body 11 and fixedly installed with the frame body 11 and the vertical partition 13, and short guide rail sliders 17 mounted on the two short guide rails 16.

[0036] It should be further explained that the interior of the frame 1 is clearly divided into physical zones, such as the power zone, dyeing zone, and control zone, by the use of horizontal partitions 12 and vertical partitions 13. At the same time, the long and short dual-rail configuration of two long guide rails 14 and sliders 15 at the rear of the frame and two short guide rails 16 and sliders 17 at the front not only ensures precise constraint on the running trajectory of the dyeing and sampling mechanism 3, but also effectively prevents the mechanism from tilting or jamming due to uneven force during the lifting process, significantly improving the operational stability.

[0037] The rectangular rack 1 also includes two cooling fans 18 installed on the top of the rack body 11, forming a top convection cooling air duct, which can effectively dissipate the heat generated by the internal electrical components, heating zone and temperature control module in a timely manner, prevent the temperature inside the rack from being too high and ensure the continuous and stable operation of the whole machine.

[0038] In this embodiment, the two cooling fans 18 are configured as an exhaust fan and an exhaust fan. The combination of one inlet and one outlet can force a directional airflow circulation within the cabinet, which greatly improves the heat dissipation efficiency. Compared with a single fan, it can better avoid local heat accumulation and significantly extend the service life of precision electronic components such as the main control board 4.

[0039] The drive mechanism 2 includes a base 21, a reducer 22 fixedly installed on one side above the base 21, a drive motor 23 fixedly installed with the reducer 22, a coupling 24 fixedly installed on the output end of the reducer 22, a flywheel 25 installed on the other side above the base 21 with its rotating shaft fixedly installed with the coupling 24, and an annular guide groove 26 opened inside the flywheel 25.

[0040] The annular guide groove 26 is eccentrically arranged, with one end close to the axis of the flywheel 25 and the other end far away from the axis of the flywheel 25.

[0041] Specifically, when the flywheel 25 rotates, the eccentric groove drives the assembly wheel to perform linear reciprocating motion, thereby driving the upper linkage rod 32 to perform smooth up and down movement. This purely mechanical eccentric transmission method is not only simple in structure, powerful, and durable, but also ensures that the dyeing and sampling mechanism 3 obtains excellent swaying amplitude and rhythm, perfectly simulating the motion state inside the actual dyeing vat.

[0042] In summary, this invention employs independent one-to-one closed-loop feedback control: a temperature sensor 349, fixed above the spring base 344, continuously contacts the bottom of the dye cup 35 to collect the actual temperature, and transmits the signal to the corresponding temperature control module 42 via the terminal 41 on the main control board 4; the temperature control module independently compares the real-time temperature with the set target and outputs instructions to the corresponding electric heating mantle 348, thereby achieving independent and precise heating and dynamic temperature control for each dye cup 35. This independent temperature control not only solves the problem of uneven heating caused by different positions of the rack edge, but also supports setting different temperature gradients or complex heating curves within the same batch, greatly improving the uniformity of dyeing and the flexibility of sampling experiments.

[0043] To more accurately describe the temperature control logic of this invention, the temperature control method of this invention is specifically divided into the following detailed steps:

[0044] Step 1: The operator inputs the required dyeing temperature conditions for each dye cup through the touch screen 5, such as constant temperature, heating rate and holding time. The touch screen 5 transmits these setting parameters to the main control board 4, and the main control board 4 accurately distributes each instruction to the temperature control module 42 corresponding to each dye cup 35.

[0045] Step 2: During the process of the driving mechanism 2 driving the dyeing and sampling mechanism 3 to shake up and down, each temperature sensor 349 fixed above the spring base 344 continuously and in real time contacts and detects the actual temperature of the bottom of the corresponding dye cup 35, and converts the temperature signal into an electrical signal, which is fed back to the corresponding temperature control module 42 through the terminal 41 on the main control board 4.

[0046] Step 3: The internal processor of the temperature control module 42 compares the received real-time feedback temperature value with the target temperature value set on the touch screen 5 to obtain the temperature difference and heating rate. At the same time, combined with the heat convection and local heat dissipation changes generated during the movement of the shaking mechanism 3, the required compensation heating power is calculated through the set PID control algorithm.

[0047] Step 4: Based on the calculation results, the temperature control module 42 independently outputs a control signal to precisely control the on / off time ratio or heating power of the electric heating jacket 348 that is electrically connected to it, so as to realize the dynamic adjustment of heating. Since the electric heating jacket 348 surrounds the dye cup 35 circumferentially, the heat is directly and efficiently transferred to the dye liquor in the cup.

[0048] Step 5: Due to the violent shaking caused by the eccentric guide groove 26, the heat dissipation of the dye cups 35 in different spatial positions is different. The system relies on the real-time feedback loop of Step 3 and Step 4 to automatically perform dynamic compensation: increase the heating power for cups with fast heat dissipation, and reduce the power or even stop heating for cups with heat accumulation, so as to ensure that all dye cups maintain the set target temperature during the shaking process.

[0049] Step Six: Once the feedback values ​​of all temperature sensors 349 reach the set target, each temperature control module 42 enters the low-power constant temperature maintenance stage. Since the temperature control closed loop of each dyeing cup 35 is completely independent, the device can support different dyeing cups at completely different temperatures in the same batch and under the same shaking state. For example, cups 1-3 are set to 60℃, cups 4-6 are set to 80℃, and cups 7-12 are set to 90℃, realizing synchronous, independent, and precise sample making at multiple temperatures in one machine until the heat preservation time ends.

[0050] The above-described step-by-step temperature control method, through a complete closed loop of "parameter setting, real-time data acquisition, dynamic calculation, independent heating, compensation balancing, and constant temperature maintenance," achieves precise one-to-one control. It completely overcomes the uneven heat distribution caused by positional differences when the equipment is violently shaken. This not only effectively prevents the damage to dye activity caused by temperature overshoot, but also supports the simultaneous execution of completely different temperature processes on different dye cups in the same batch. This significantly improves the reproducibility of sampling experiments, the efficiency of multi-tasking parallelism, and the overall stability and maintainability of the system.

[0051] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention. The implementation of the present invention is not limited thereto. All other modifications, substitutions or alterations made to the above structure of the present invention based on the above content of the present invention, in accordance with ordinary technical knowledge and common practice in the field, without departing from the basic technical idea of ​​the present invention, shall fall within the scope of protection of the present invention.
