Description

Technical Field

[0001] The present invention relates to a single-machine test method and a control system, in particular to a single-machine test method and a control system suitable for a carding machine, and belongs to the technical field of yarn preparation. Background Art

[0002] Yarn weaving mainly includes opening and cleaning, carding, drawing, and spinning processes. After the drawing process, the sliver quality inspection generally includes four items: sliver weight uniformity, sliver dryness uniformity, nep impurities and short fiber rate. Among them, the nep impurities and short fiber rate of the sliver have a direct impact on the appearance and strength of the yarn, and seriously affect the production efficiency of the subsequent processes.

[0003] Currently, specialized equipment that can directly detect neps, impurities, and short-lint content in sliver produced by carding machines is expensive (typically ¥400,000-500,000, such as the Uster AFIS Pro 2 single fiber tester, developed by Uster and capable of measuring single fiber length, fineness, dust, visible foreign matter, and fiber neps). Ordinary spinning mills cannot afford such expensive testing equipment, so they typically use the manual black and white plate method to test neps and the roller analysis method to test short-lint content. However, individual visual differences lead to large detection errors and low efficiency, and the test results cannot be positively correlated with yarn neps and defects, thus failing to provide effective test data support for production operations.

[0004] The prior art "FA203 Carding Machine Process Performance Test, Zhang Xiaonan" discloses routine testing using an Afis tester and USTER testing of all indicators, except for the thick places, which reached 50% of the USTER 89 standard, reaching 25%. "Development and Testing of a Fully Fixed Flat Carding Machine, Xiao Jianming" discloses sliver quality testing (manual sorting), involving items such as sliver delivery speed, neps, trash particles, and short lint rate. CN101962827A discloses a "Digital Carding Tester," which utilizes digital technology and is suitable for rapid testing of small carding samples. CN215328513U aims to overcome the drawbacks of existing methods for testing cohesion force, which involve complex procedures and only reflect the cohesion force at the end of the carding process, rather than the fiber gathering during the entire carding process. Instead, it provides a simple carding machine cohesion force testing device that can measure both the cohesion force at the end of the carding process and the fiber gathering during the entire carding process.

[0005] Therefore, there is an urgent need for a measurement method that can comprehensively reflect the status of the carding machine to provide reference data for process formulation, maintenance, etc. Summary of the Invention

[0006] To address the existing issues of expensive specialized carding machine testing equipment and large manual testing errors, a single-machine carding machine testing method and control system was proposed, combining the existing production line layout (a draw frame is located behind the carding machine process, and a spinning machine is located behind the draw frame workstation). This technical solution, based on the existing manual nep counting system, adds a set of rapid spinning tests for a single carding machine under test. Utilizing online monitoring of the eddy current spinning machine (or winder) and electronic yarn clearer (electrical yarn clearer), this method quickly determines the status of the carding machine under test and compares it to the results of the carding process test. This avoids data errors caused by manual nep counting and insufficient sampling for laboratory testing. Ultimately, this method enables single-machine carding machine testing, providing an effective reference for production needs.

[0007] In order to achieve the above technical objectives, the following technical solutions are proposed:

[0008] The first purpose of this technical solution is to propose: a single-machine test method for a carding machine, comprising the following steps:

[0009] A. Use the carding machine to simulate normal production to obtain test card sliver for future use;

[0010] B. Use a drawing frame to draw the raw sliver produced by the same carding machine to be tested to obtain the test sliver for future use;

[0011] C. Use a spinning machine to prepare yarn from the test sliver and test the yarn's performance;

[0012] Among them, yarn indicators include yarn evenness, cut quality and yarn defects (100km yarn), and yarn defects include neps, thick places and thin places;

[0013] D. Establish a carding machine rating system;

[0014] E. Referring to the carding machine grade evaluation system obtained in step D and combining it with the yarn index obtained in step C, obtain the test results of the carding machine to be tested;

[0015] If the carding machine grade evaluation system requirements are met, the carding machine to be tested is directly used on the production line to produce card sliver;

[0016] If the requirements of the carding machine grade evaluation system are not met, the carding machine to be tested shall be debugged and optimized, and the above test method shall be carried out again until the requirements of the carding machine grade evaluation system are met. It can then be used on the production line to produce sliver.

[0017] Preferably, before the carding machine to be tested in step A produces raw sliver, the directly purchased carding machine is pretreated, and the pretreatment includes: washing, inspection, debugging and start-up preheating, which are routine pretreatments before the normal use of the existing carding machine, eliminating factors such as the deterioration of sliver quality due to internal flower hanging in the equipment.

[0018] Preferably, in step A, the carding machine to be tested produces 4-8 carded slivers.

[0019] Preferably, in step B, the drawing process includes primary drawing, secondary drawing, and tertiary drawing. In the primary drawing process, the sliver produced by the same carding machine to be tested is drawn; in the secondary drawing process, the sliver produced by the same first drawing frame is drawn; and in the tertiary drawing process, the sliver produced by the same second drawing frame is drawn. This reduces the impact of different drawing frames on subsequent yarns, thus achieving a single control variable method in this test method when testing the carding machine to be tested.

[0020] Preferably, in step B, 4-8 raw strips are used to produce a drawing strip through a drawing frame.

[0021] Preferably, in step D, a carding machine grade evaluation system is established by testing the average 100 km shearing conditions of the spindle position, and the carding machine grade evaluation system includes: vortex spinning shear number ≤ 4 is grade A, 4 < shear number ≤ 6 is grade B, 6 < shear number ≤ 9 is grade C, and > 9 is grade D.

[0022] The second purpose of this technical solution is to propose: a computer-readable storage medium, including instructions, which, when run on a computer, enable the computer to execute a single-machine testing method applicable to a carding machine.

[0023] The third purpose of this technical solution is to propose: a control system suitable for single-machine testing of a carding machine, including a control center, a pretreatment control module, a carding control module, a drawing control module, a spinning control module, a yarn index collection module, a grade evaluation system establishment module, an evaluation module and a debugging module, wherein:

[0024] The control center is used to issue instructions to the control module and collect and analyze yarn index information;

[0025] A pretreatment control module, used for controlling the pretreatment equipment to perform pretreatment on the carding machine to be tested;

[0026] Carding control module, used to control the carding machine to be tested to produce test card sliver;

[0027] The drawing control module is used to control the production of test slivers by the drawing frame using the test slivers as raw materials;

[0028] The spinning control module is used to control the production of test yarn using a spinning machine with the test sliver as raw material;

[0029] Yarn index collection module, used to obtain test yarn index information: evenness, cut, neps, thick places and thin places;

[0030] Grade evaluation system establishment module, used to establish a grade evaluation system for carding machines;

[0031] An evaluation module evaluates the carding machine grade based on the obtained test yarn index information and the carding machine grade evaluation system;

[0032] The debugging module is used to debug the carding machine that does not meet the carding machine grade evaluation system.

[0033] Among them, the pre-processing control module includes a car washing unit, an inspection unit, a debugging unit and a preheating unit.

[0034] Among them, the yarn index collection module includes an electronic yarn clearer.

[0035] The beneficial technical effects brought about by adopting this technical solution are:

[0036] In the present invention, a single-machine experimental method and a carding machine grade evaluation system are established for the carding machine, which can quickly (2-3 hours) and accurately obtain test data, and judge the condition of a single carding machine by the yarn index spun by the test sliver, which is conducive to mobilizing forces to carry out rectification work on poor machines. After rectification, the machine can also verify the accuracy of the rectification ideas and directions through the single-machine experimental method, avoiding the problem of not being able to quickly obtain rectification results, resulting in slow progress of rectification work;

[0037] This application combines the existing layout of the production line (a drawing frame is provided at the rear side of the process of the carding machine, and a spinning machine is provided at the rear side of the work station of the drawing frame) to realize a single-machine test method of the carding machine to be tested without adding additional detection equipment and its layout. That is, this technical solution adds a set of rapid trial spinning for a single carding machine to be tested on the basis of the existing manual counting of cotton neps. By utilizing the online monitoring of the vortex spinning machine and the electronic yarn clearer (electric clearer), the status of the carding machine to be tested and the comparison of the carding process test can be quickly determined, avoiding data errors caused by manual counting of cotton neps and too small sampling volume for laboratory testing, and finally realizing the single-machine test of the carding machine, providing an effective reference for production needs, thereby ensuring the feasibility of this method.

It is obvious that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Figure 1 The specific test process is as follows:

[0048] 1) Pre-treat the carding machine to be tested using conventional operations in this field, including washing, inspection, commissioning, and preheating (e.g., running the carding machine for 30 minutes to stabilize the heat generated by the components in the carding machine);

[0053] 6) Ten test spindles were selected on the vortex spinning machine, and three-way test slivers were placed on the test spindles for spinning. At the same time, the spinning length, shear number, yarn evenness, thick places, thin places and neps were recorded during the spinning period of 1 hour using the online monitoring of the vortex spinning machine and the electric clearer.

[0054] 7) Based on the collected data indicators: spinning length, shear number, yarn evenness, thick places, thin places and cotton neps, the grade of the carding machine to be tested is evaluated and the status of the carding machine is determined, thus completing the single-machine test of the carding machine.

[0055] Through the above-mentioned grade evaluation results of the carding machine to be tested, the level status of the carding machine to be tested can be understood, and then the equipment can be directly used or adjusted to meet the actual needs of the production line.

[0064] 6) Ten test spindles were selected on the vortex spinning machine, and three-way test slivers were placed on the test spindles for spinning. At the same time, the spinning length, shear number, yarn evenness, thick places, thin places and neps were recorded during the spinning period of 1 hour using the online monitoring of the vortex spinning machine and the electric clearer.

[0091]

[0092] Example 5

[0093] On the basis of Examples 1-4, this embodiment proposes: a computer-readable storage medium, comprising instructions, which, when executed on a computer, enables the computer to execute a single-machine test method applicable to a carding machine.

[0094] Example 6

[0095] This embodiment proposes: a control system suitable for a single-machine test of a carding machine, such as Figure 5As shown, it includes a control center, a pretreatment control module, a carding control module, a drawing control module, a spinning control module, a yarn index collection module, a grade evaluation system establishment module, an evaluation module and a debugging module, among which,

[0096] The control center is used to issue instructions to the control module and collect and analyze yarn index information;

[0097] A pretreatment control module, used for controlling the pretreatment equipment to perform pretreatment on the carding machine to be tested;

[0098] Carding control module, used to control the carding machine to be tested to produce test card sliver;

[0099] The drawing control module is used to control the production of test slivers by the drawing frame using the test slivers as raw materials;

[0100] The spinning control module is used to control the production of test yarn using a spinning machine with the test sliver as raw material;

[0107] Control Example

[0108] Based on the present invention and the existing layout of the actual production line (a drawing frame is provided at the rear of the carding machine, and a spinning machine is provided at the rear of the drawing frame), a single-machine test method of the carding machine is adopted ( Figure 3 ) and actual production ( Figure 4 ), it was found that: the variables involved were reduced, and the status judgment of a single test machine was faster and more accurate. The results of the comparison between the single-machine test method and the actual production process are detailed in Table 2.

[0109]

[0110] At the same time, it can be seen that the original actual production process is unable to track the status of a single carding machine. Using the average indicators of multiple carding machines as the judgment basis, it is impossible to objectively and accurately determine the status of the carding machine and the comparative results of the carding process test. According to the results of comparing the single-machine test method with the actual production process, in terms of the application of determining the status of the carding machine and the comparative results of the carding process test, the single-machine test has greater advantages in terms of auxiliary equipment, number of cans used, material consumption, labor, etc., and can objectively and accurately determine the status of the carding machine and the comparative results of the carding process test, and draw test conclusions.
