Description

Technical Field

[0001] This invention relates to the field of textile testing technology, specifically an automated device for detecting the fiber content of textile samples. Background Technology

[0002] Fiber content testing of textiles is a crucial step in ensuring their quality and safety. Before testing, a series of complex pretreatment procedures are required for the fabric samples, mainly including precise cutting, weighing, dissolving, stirring, washing, and waste discharge. Currently, the industry commonly uses a combination of manual operation and single-function equipment to complete these processes: operators must use a sample crusher to crush the sample, weigh it with a balance, transfer the sample to beakers or flasks for manual liquid addition and stirring, and repeatedly transfer the sample and container between different steps. Furthermore, the chemical dissolution process may also involve heating and the treatment of hazardous waste.

[0003] This traditional operating mode has significant drawbacks: 1. The process is fragmented, relying on manual coordination of each step, resulting in low efficiency and high labor intensity; 2. Manual operation is prone to introducing weighing errors, sample confusion, or cross-contamination, affecting the accuracy and reproducibility of test results; 3. Operators are directly exposed to the potential hazards of dust generated by sample breakage, as well as chemical solvents and exhaust gases, posing a high health risk; 4. Although some automated single-machine equipment (such as automatic balances) already exists, the equipment is independent of each other and cannot form a closed, coherent, and intelligent collaborative complete solution, resulting in limited automation and intelligence levels.

[0004] Therefore, there is an urgent need to develop an automated device for detecting the fiber content of textile samples to solve the problems in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide an automated device for detecting the fiber content of textile samples. This device can solve the problems of low efficiency, large operational errors, and personnel exposure to dust and chemical reagents caused by the dispersed process and reliance on manual transfer of samples and containers in the pretreatment of textile samples for fiber content detection. It is also simple in structure and easy to use, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automated device for detecting the fiber content of textile samples, comprising: Mainframe rack; An integrated processing chamber is fixedly installed on the main frame. The integrated processing chamber is equipped with a sample carrier plate and a rotating mechanism inside. The sample carrier plate is fixedly connected to the integrated processing chamber, and the rotating mechanism is fixedly connected to the integrated processing chamber. A multi-functional top cover is provided at the top opening of the integrated processing chamber. The multi-functional top cover is connected to the integrated processing chamber in an opening and closing manner. The multi-functional top cover is provided with a sample crushing knife, a liquid addition nozzle and a stirrer. The bottom functional module is located at the bottom of the integrated processing chamber, and the bottom functional module is equipped with a weighing sensor, a heating plate and a waste liquid discharge port. A central controller is fixedly connected to the main frame and electrically connected to the stirrer, the weighing sensor and the heating plate. The sample carrier plate is driven by the rotating mechanism and can rotate in the horizontal plane; the integrated processing chamber is used to sequentially complete the operations of crushing, dissolving, stirring, weighing and discharging waste liquid of the textile sample placed on the sample carrier plate.

[0007] By adopting the above technical solution, the functions of sample crushing, liquid addition, stirring, heating, weighing, and waste liquid treatment are integrated into a closed processing chamber. Specifically, driven by a rotating mechanism, the sample carrier tray can rotate stepwise in the horizontal plane, thereby sequentially delivering the sample placed on the carrier tray to different workstations corresponding to the functional components on the top cover. This "intra-chamber workstation switching" working method realizes continuous operation of the entire process from sample crushing, reagent addition, dissolution and stirring, process weighing to waste liquid discharge. The entire process does not require manual transfer of samples or replacement of containers, which simplifies the equipment structure while improving processing efficiency and operational closedness.

[0008] As a further aspect of the present invention: the multifunctional top cover is provided with an electric push rod, the sample crushing tool is driven by the electric push rod, and the electric push rod can move up and down to contact or move away from the sample on the sample carrier plate.

[0009] By adopting the above technical solution, an electric push rod is used as the direct drive component for the sample crushing cutter. Its working principle is as follows: when the sample crushing process needs to be performed, the central controller instructs the motor of the electric push rod to rotate forward, pushing the push rod downwards, thereby driving the sample crushing cutter fixed at its end downwards until it contacts and crushes the sample located on the support plate; after crushing is completed, the controller instructs the motor to reverse, pulling the push rod and cutter upwards back to their original positions. This structure achieves precise control of the vertical movement of the cutter, ensuring that it only intervenes during sample crushing and can avoid obstacles in time, leaving operating space for subsequent processes such as liquid addition and stirring.

[0010] As a further aspect of the present invention: the main frame is provided with a solvent storage tank and a water tank, and the liquid dispensing nozzle is connected to the solvent storage tank and the water tank through a pipeline, and a first solenoid valve controlled by the central controller is provided on the pipeline.

[0011] By adopting the above technical solution, an external solvent storage tank and water tank are installed and connected to a liquid dispensing nozzle on the top cover via pipelines. Its working principle is as follows: the central controller sends opening and closing commands to the first solenoid valve on a specific pipeline according to a preset program. When a certain liquid needs to be added, the solenoid valve on the corresponding pipeline opens, and the liquid in the storage tank or water tank, assisted by gravity or an external micro-pump, is quantitatively sprayed into the processing chamber through the nozzle via the pipeline. This design achieves programmed automatic addition of different types and dosages of liquids, replacing traditional manual measurement and pouring, and ensuring the accuracy and consistency of liquid dispensing.

[0012] As a further aspect of the present invention: the stirrer includes: a rotating shaft and a blade, the rotating shaft is rotatably connected to the multifunctional top cover, the blade is fixedly connected to the rotating shaft, the interior of the rotating shaft is hollow, and an airflow channel is formed inside the rotating shaft. When an external air source supplies air to the airflow channel, the reaction force of the outflowing gas drives the rotating shaft and the blade to rotate.

[0013] By adopting the above technical solution, a pneumatically driven agitator is employed. Its working principle is as follows: gas supplied by an external air source is introduced into the airflow channel inside the rotating shaft via a control valve and ejected at high speed from nozzles located at a specific angle on the side wall or bottom of the shaft. According to Newton's third law, the ejected gas generates a counterforce on the rotating shaft, which forms the torque driving the shaft to rotate, thereby causing the impeller fixed at the lower part of the shaft to rotate and agitate the liquid inside the chamber. This driving method eliminates the need for a strictly sealed drive motor in corrosive environments, improving the system's environmental adaptability and reliability.

[0014] As a further aspect of the present invention, the outlet direction of the airflow channel is set to form a certain angle with the blades of the propeller to optimize the driving efficiency of the gas thrust on the rotation.

[0015] By adopting the above technical solution, the airflow outlet direction of the pneumatic agitator was optimized. Specifically, by setting the central axis of the airflow nozzle to form an acute angle (rather than perpendicular) with the radial plane of the blade, the reaction force vector of the ejected airflow can be decomposed into a larger tangential component. This tangential component directly contributes to the effective torque driving the shaft rotation, thereby achieving a higher stirring speed or stronger stirring force under the same gas flow rate and pressure, thus optimizing energy utilization efficiency.

[0016] As a further aspect of the present invention: the heating plate is annular, with a first through hole in its middle, and the sensing end of the weighing sensor passes through the first through hole and is fixedly connected to the lower surface of the sample support plate.

[0017] By adopting the above technical solution, a structure integrating heating and weighing functions is employed. Its mechanical principle is as follows: a ring-shaped heating plate is arranged around the weighing sensor, and the heat generated by it uniformly heats the sample support plate located above it primarily through thermal radiation and conduction. Simultaneously, the sensing end of the weighing sensor (such as a weighing rod) passes through a first through-hole in the center of the heating plate, directly supporting and sensing the weight of the sample support plate through point or surface contact. This arrangement achieves separation and nesting of the heating surface and the weighing force transmission path in physical space, enabling real-time and uninterrupted monitoring of the mass changes of the sample and its support device during continuous heating.

[0018] As a further aspect of the present invention: the rotating mechanism includes a stepper motor and a gear transmission assembly. The stepper motor is fixedly connected to the outside of the integrated processing cavity, and its output shaft is connected to the central shaft of the sample carrier disk through the gear transmission assembly.

[0019] By adopting the above technical solution, a stepper motor combined with a gear transmission assembly is used as the drive scheme for the rotating mechanism. Its working principle is as follows: the central controller sends a specific number and frequency of pulse signals to the stepper motor, controlling its output shaft to rotate precisely by a certain angle. The output torque of the stepper motor, after being reduced and increased in torque through the gear transmission assembly, is transmitted to the central shaft of the sample carrier plate, driving the carrier plate to perform corresponding intermittent rotational motion. The gear transmission ratio design ensures that the carrier plate has sufficient rotational accuracy and positioning stability, thereby enabling the sample to be accurately stopped and positioned at multiple functional stations such as sample crushing, liquid addition / stirring, and weighing.

[0020] As a further aspect of the present invention: a waste liquid collection tank is provided on the main frame, and the waste liquid discharge port is connected to the waste liquid collection tank through a second solenoid valve, which is controlled by the central controller.

[0021] An automated waste liquid discharge and collection system was established using the aforementioned technical solution. Its working principle is as follows: After processes such as dissolution and cleaning are completed, the accumulated waste liquid in the processing chamber is located on the sample support plate or at the bottom of the chamber. At this time, the central controller issues a command to open the second solenoid valve located in the waste liquid discharge port pipeline. Under the action of gravity, the waste liquid flows through the discharge port into the connecting pipeline and finally into the waste liquid collection tank on the main frame. After the valve closes, the system returns to a sealed state. This process achieves automated and closed-loop transfer of waste liquid, avoiding manual contact and handling of hazardous waste liquid.

[0022] Compared with the prior art, the beneficial effects of the present invention are: it can solve the problems of low efficiency, large operation error, and personnel exposure to dust and chemical reagents caused by the dispersed process and reliance on manual transfer of samples and containers in the pretreatment of existing textile samples for fiber content detection.

[0026] 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. Example 1:

[0027] This embodiment provides the basic structure of an automated device for detecting the fiber content of textile samples and a standardized sample pretreatment method.

[0028] Reference Figures 1 to 3 As shown, the automated device for testing textile samples includes a main frame 1. An integrated processing chamber 2 is fixedly mounted on the main frame 1. The integrated processing chamber 2 is preferably cylindrical and made of a chemically resistant material.

[0029] A sample carrier tray 21 is located at the center of the integrated processing chamber 2. The sample carrier tray 21 is preferably a circular tray, and its edges may have positioning grooves or markings. The sample carrier tray 21 is driven by a rotating mechanism 22, enabling precise step-by-step rotation in the horizontal plane. The rotating mechanism 22 includes a stepper motor 221 and a gear transmission assembly 222. The stepper motor 221 is fixedly connected to the outer wall of the integrated processing chamber 2 via a mounting base, and its output shaft passes through the chamber wall and is connected to the central axis of the sample carrier tray 21 via the gear transmission assembly 222.

[0030] The integrated processing chamber 2 has an opening at its top, and a multi-functional top cover 3 is connected to the opening via a hinge or slide rail. The multi-functional top cover 3 can be opened or closed relative to the integrated processing chamber 2. The multi-functional top cover 3 integrates three core functional components: a sample crushing blade 31, a liquid dispensing nozzle 32, and a stirrer 33.

[0031] The sample crushing cutter 31 is driven by an electric push rod 34. The cylinder of the electric push rod 34 is fixedly connected to the inner top wall of the multi-functional top cover 3, and the end of its push rod is fixedly connected to the blade holder of the sample crushing cutter 31, thereby realizing the precise vertical lifting and lowering movement of the sample crushing cutter 31.

[0032] The dispensing nozzle 32 is connected to an external solvent storage tank 11 and water tank 12 via a piping system. The solvent storage tank 11 and water tank 12 are fixedly mounted on the main frame 1. Each connecting pipe is equipped with a first solenoid valve 51 controlled by the central controller 5, which is used to precisely control the timing and flow rate of dispensing different liquids.

[0033] The agitator 33 includes a hollow rotating shaft 331 and multiple blades 332 fixed to the lower part of the rotating shaft 331. The rotating shaft 331 is rotatably connected to the multi-functional top cover 3 via bearings. The internal cavity of the rotating shaft 331 forms an airflow channel, and its lower end sidewall has a jet hole at a certain angle to the plane of the blades 332. An external air source (not shown in the figure, such as an air compressor) is connected to the upper end of the rotating shaft 331 through a hose. When high-pressure gas is introduced, the reaction force generated by the airflow ejected from the jet hole drives the rotating shaft 331 and the blades 332 to rotate.

[0034] The bottom of the integrated processing cavity 2 is equipped with a bottom functional module 4. The bottom functional module 4 integrates three functional units: Weighing sensor 41 is used to measure the mass of sample carrier plate 21 and the object on it in real time.

[0035] The heating plate 42, which is a ring structure, surrounds the weighing sensor 41 and is used to heat the sample carrier plate 21. A first through hole 421 is provided in the middle of the heating plate 42.

[0036] Waste liquid discharge port 43 is connected to waste liquid collection tank 44 on main frame 1 via a pipeline. A second solenoid valve 52 controlled by central controller 5 is installed on this connecting pipeline.

[0037] The sensing end of the weighing sensor 41 (such as a weighing rod) passes through the first through hole 421 of the heating plate 42 from bottom to top and is fixedly connected to the center of the lower surface of the sample carrier plate 21. This structure realizes the physical spatial integration and synchronous operation of the heating function and the real-time weighing function.

[0038] The central controller 5 is fixedly mounted on the main frame 1 and is electrically connected to the stepper motor 221, the electric push rod 34, each of the first solenoid valves 51, the stirrer 33 (controlled by a solenoid valve that controls an external air source), the weighing sensor 41, the heating plate 42, and the second solenoid valve 52. The central controller 5 has a built-in control program to coordinate the various components to work together according to a preset process.

[0039] The textile sample pretreatment method of this embodiment includes the following steps: S1. Sample Submission and Initial Weighing: Open the multi-functional top cover 3, and the operator places a sample of the textile to be tested (such as a fabric fragment) in the designated position on the sample carrier plate 21, and then closes the multi-functional top cover 3. The central controller 5 reads the initial data from the weighing sensor 41 and records the initial total mass (M0) of the sample and the carrier plate.

[0040] S2. Automatic Sample Crushing: The central controller 5 instructs the rotating mechanism 22 to operate, and the stepper motor 221 drives the sample carrier plate 21 to rotate, precisely rotating the sample-carrying position to directly below the crushing blade 31. Subsequently, the controller instructs the electric push rod 34 to extend, pushing the crushing blade 31 downward to cut or crush the sample. After completion, the crushing blade 31 rises back to its original position.

[0041] S3. Reagent Addition and Heating Dissolution: The sample carrier plate 21 rotates to a position below the dispensing nozzle 32. According to a preset program, the central controller 5 opens the first solenoid valve 51 connected to the specific solvent storage tank 11, quantitatively spraying a dissolving reagent (such as sulfuric acid or sodium hydroxide solution) onto the sample through the dispensing nozzle 32. Subsequently, the controller activates the heating plate 42 to heat the sample carrier plate 21 at a constant or programmed temperature, promoting the chemical dissolution of the textile fibers. During this process, the weighing sensor 41 continuously monitors the change in total mass, and the data is fed back to the central controller 5 in real time.

[0042] S4. Pneumatic Stirring and Process Monitoring: The sample carrier plate 21 rotates to a position below the stirrer 33. The central controller 5 opens the control valve of the external air source, and compressed gas enters the airflow channel of the rotating shaft 331 and is ejected at high speed from the jet hole, driving the impeller 332 to rotate and thoroughly stir the mixed liquid in the chamber, accelerating the dissolution reaction and ensuring homogeneity. During or after stirring, the sample carrier plate 21 can be rotated again to the weighing position (i.e., directly above the weighing sensor 41) to measure the process mass (M1). By comparing M0 and M1, the mass lost through dissolution can be calculated.

[0043] S5. Cleaning and Neutralization (Optional): According to the testing standards, the controller can instruct the first solenoid valve 51 connected to the water tank 12 to spray distilled water or deionized water to clean the residue. If necessary, neutralizing reagent can be added.

[0044] S6. Waste Discharge and Sample Preparation Completed: After all current processing steps (dissolution, washing, etc.) are completed, the central controller 5 opens the second solenoid valve 52. Under gravity, the waste liquid in the integrated processing chamber 2 is discharged into the waste liquid collection tank 44 through the waste liquid discharge port 43. After discharge, the valve closes. At this time, the sample carrier tray 21 contains pretreated solid residues that can be used for component analysis. The controller can record the final mass (M2). The entire process does not require manual opening of the chamber or transfer of sample containers. Example 2:

[0045] This embodiment, based on Embodiment 1, focuses on illustrating the operation mode of the device for continuous batch sample processing.

[0046] The sample carrier tray 21 is designed to have multiple independent stations (e.g., 4 or 6) evenly distributed along its circumference. Each station can hold a sample container or directly carry one sample.

[0047] During operation, the operator places multiple samples into different workstations at once. The central controller 5 controls the rotating mechanism 22, causing the sample carrier plate 21 to rotate intermittently, cyclically sending each workstation to a fixed processing position (sample crushing station, liquid addition / stirring station, weighing station).

[0048] In this mode, the device can operate efficiently: Mode A (Sequential Assembly Line): While the sample at station 1 is being crushed, the sample at station 2 may have already been crushed and rotated to the liquid addition position, the sample at station 3 may be being stirred, and the sample at station 4 may be being weighed. This cycle repeats, achieving near-assembly line-like continuous operation, greatly improving equipment utilization and processing efficiency.

[0049] Mode B (Programmed Grouping Processing): The central controller 5 can program and control different workstations to perform differentiated processing procedures (such as using different solvents, different heating temperatures or times) according to the detection requirements of different samples.

[0050] Throughout the batch processing, the multi-functional top cover 3 is only opened during the initial batch sampling and when maintenance may be required at the end, maximizing the secrecy of the operation and reducing the risk of environmental pollution and personnel exposure. Example 3:

[0051] This embodiment, in conjunction with the device structure of Embodiment 1, illustrates its technical advantages in dealing with special detection scenarios.

[0052] Scenario 1: Reliability in handling highly corrosive solvents. When testing requires strong acids, strong alkalis, or organic solvents, traditional motor-driven stirrers risk seal failure leading to motor corrosion and damage. This device's stirrer 33 is pneumatically driven. Its shaft 331 and the multi-functional top cover 3 require only a conventional rotary seal to prevent liquid leakage, while the drive power source (compressed gas) is located outside the chamber. This design fundamentally avoids direct contact between the drive components and corrosive media, significantly improving the long-term operational reliability and service life of the device in harsh chemical environments.

[0053] Scenario 2: Real-time quality monitoring of the dissolution process. In certain quantitative chemical analyses, it is necessary to accurately monitor the mass change curve of fibers over time during the dissolution process (dissolution kinetics). Traditional methods require interrupting heating, removing the sample for weighing, resulting in discontinuous data and potential errors. This device, due to its integrated design of heating plate 42 and weighing sensor 41 (annular heating plate and central through-hole), allows the weighing sensor 41 to continuously monitor and transmit the mass change of the sample to the central controller 5 in real time while the sample is continuously heated and undergoing the dissolution reaction. The controller can record and plot the mass versus time curve, providing an in-situ detection method for in-depth research on fiber dissolution characteristics.

[0054] Scenario 3: Waste Liquid Classification and Safety Management. By upgrading the program of the central controller 5 and modifying the piping system, a multi-way valve can be added to the waste liquid discharge pipeline. After processing samples using acidic reagents, the device can discharge the waste liquid into the "acidic waste liquid collection tank"; after processing samples using alkaline reagents, the waste liquid can be discharged into the "alkaline waste liquid collection tank." This automatic classification and collection function facilitates the professional and environmentally friendly treatment of hazardous waste liquids of different properties, further improving the automation and safety management level of the laboratory.

[0055] This invention provides an automated device for detecting the fiber content of textile samples. It can solve the problems of low efficiency, large operational errors, and personnel exposure to dust and chemical reagents caused by the dispersed process and reliance on manual transfer of samples and containers in the pretreatment of textile samples for fiber content detection. It has high reliability.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
