Description

Technical Field

[0001] The invention relates to the technical field of textile equipment, in particular to a yarn detection mechanism of a sizing machine and a detection process thereof. Background Art

[0002] Sizing is an important process in textile production. Its purpose is to improve the strength, smoothness and wear resistance of the yarn by applying a layer of sizing agent on the warp yarn, thereby improving the performance in the weaving process. The sizing machine is the equipment used to complete this process.

[0003] Before sizing the yarn of natural fibers such as cotton and linen or some synthetic fibers, the fiber surface needs to be steam-wetted to improve the adhesion between its surface and the sizing agent. When steam-wetting the yarn, it is particularly important to control the amount of steam. If the steam is excessively wetted, the sizing agent attached to the yarn after sizing will be too thin, and the strength of the yarn after sizing will not meet the requirements. If the steam is too little, the adhesion of the yarn will not be greatly improved, resulting in insufficient sizing agent attached during sizing.

[0004] The existing yarn wetting adjustment is usually based on adjusting the amount of steam entering, and the adjustment standard needs to be based on the amount of slurry attached to the yarn after passing through the slurry tank or the strength of the yarn after drying. It is difficult to achieve the requirement of real-time steam adjustment for the yarn in the steam wetting process. Not only is the adjustment accuracy poor, but the timeliness is also low, which is not conducive to improving high-quality production efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a yarn detection mechanism for a sizing machine and a detection process thereof, thereby being able to detect the moisture wetting effect of the yarn in a steam box in real time and improving the accuracy of yarn wetting.

[0006] In order to solve the above technical problems, the present invention solves them through the following technical solutions: a yarn detection mechanism of a sizing machine includes a steam box, a sizing tank and a drying box.

[0007] In the above scheme, preferably, the bottom of the steam box is provided with a detection unit for detecting the water absorption of the yarn; The steam box is movably provided with a door body for the detection unit to pass through; The detection unit includes a plurality of yarn segments and a fixing frame for fixing two ends of the yarn segments; The steam box is provided with a lifting push rod connected to the fixing frame; The fixed frame has a sliding disk for fixing the yarn segment on one side, and a rotating disk for fixing the other end of the yarn on the other side; The detection unit also includes a detection tank for storing moisture on the yarn segment.

[0013] In the above scheme, preferably, a first pump body for discharging liquid in the tank and a second pump body for injecting liquid into the tank are provided at the bottom of the detection tank.

[0014] In the above scheme, preferably, a hot air blower for injecting dry hot air into the drying box is provided in the drying box, and the hot air blower is connected to the first hot air pipe to synchronously deliver hot air to the detection box.

[0015] In the above scheme, preferably, the detection liquid is a conductive liquid. When water enters the conductive liquid, the liquid concentration can be reduced, thereby reducing the conductive performance of the liquid, thereby realizing the measurement of the amount of added water.

[0016] In the above scheme, preferably, a detection process of a yarn detection mechanism of a sizing machine is as follows: S1: The continuous yarn enters the steam box for wetting, then passes through the sizing tank for sizing, and then enters the drying box for drying to complete the sizing process; S2: The detection unit enters the steam box through the lifting push rod to perform regular and frequent detection; S3: After the fixed frame is placed in the steam box for a period of time, the yarn segment absorbs a certain amount of steam, and then the lifting push rod drives the fixed frame to descend and fall back into the detection box; S4: Then the transmission wheel is meshed with the driving wheel, and the driving motor is started to rotate the rotating disk relative to the sliding disk, so that each yarn segment is twisted, and the water in the yarn segment is squeezed out and falls into the detection tank; S5: After the detection liquid in the detection tank is mixed with water, the concentration is reduced, and the conductivity of the detection liquid is fed back to the controller through the first conductive element and the second conductive element to determine the moisture absorption amount of the yarn segment.

[0017] The beneficial effects of the present invention are as follows: the present invention provides a detection mechanism and a detection process for the wetting of the yarn of a sizing machine in a steam box, through which the moisture absorption of the yarn can be detected at regular intervals and times, thereby achieving real-time detection and improving the accuracy of the yarn wetting, which significantly improves the subsequent regulation of the steam volume and the improvement of the sizing quality of the yarn, greatly improving the production efficiency while further improving the sizing quality of the yarn.

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 4 A yarn detection mechanism for a sizing machine includes a steam box 1, a sizing tank 2 and a drying box 3. The steam in the steam box 1 can be controlled by an electric steam valve. After being moistened by the steam box 1, the continuous yarn enters the sizing tank 2 for yarn sizing adhesion. Subsequently, the yarn adhered to the sizing enters the drying box 3 for drying to complete the sizing.

[0023] In order to perform real-time detection on the water absorption of the yarn entering the steam box 1, a liftable detection unit 4 is provided at the bottom of the steam box 1. Specifically, a detection box 5 is connected to the bottom of the steam box 1. The steam box 1 and the detection box 5 are connected via a rotatable door body 101. In the initial state, the shape of the door body 101 matches the steam box 1 to form an integral steam box. Both ends of the door body 1 are rotatably connected to the steam box 1 via pins. When the detection unit 4 is lifted upward, the door body 1 can be pushed open, so that the detection unit 4 can enter the steam box 1 for detection.

[0024] The detection unit 4 includes a fixing frame 402 and a plurality of yarn segments 401 disposed on the fixing frame 402. The yarn segments 401 have the same diameter and material as the yarn entering the steam box 1, that is, they are the same type of yarn; Figure 1-3As shown, a sliding disk 404 is slidably provided at the left end of the fixed frame 402, and a rotating disk 405 is rotatably provided at the right end. The sliding disk 404 and the rotating disk 405 have the same appearance. Both ends of the yarn segment 401 are fixed on the sliding disk 404 and the rotating disk 405 and are in a straightened state.

[0025] The yarn segments 401 are arranged in several groups around the center of the rotating disk 405 or the sliding disk 404 and are evenly arranged around the circumference, such as Figure 4 As shown, the more yarn segments there are, the higher the detection accuracy is; the left end of the sliding disk 404 slides through the fixed frame 402 through the sliding shaft 411, and the sliding shaft 411 can be set as a hexagonal shaft. A sliding hole 412 matching the sliding shaft 411 is provided on the left vertical plate of the fixed frame 402, and the sliding hole 412 can be set as a hexagonal hole matching the hexagonal shaft, so that the sliding disk 404 slides horizontally relative to the fixed frame 402, and the sliding disk 404 is connected to the fixed frame 402 through a first spring 407, and the first spring 407 is a tension spring.

[0026] The rotating disk 405 is rotatably arranged on the right vertical plate of the fixed frame 402 through a rotating shaft, and the rotating shaft is connected to a transmission wheel 408 after passing through the right vertical plate, that is, the rotating disk 405 is rotatably clamped on the right vertical plate; when the transmission wheel 408 rotates, it can drive the rotating disk 405 to rotate. At this time, the sliding disk 404 is in a guided sliding state and cannot rotate synchronously with the rotating disk 405, so that the yarn segment 401 fixed between the rotating disk 405 and the sliding disk 404 in a straightened state is entangled, and the moisture in the yarn segment 401 is squeezed out. The total amount of moisture extruded is matched with the number of yarn segments to achieve the measurement of the water absorption of a single yarn segment 401.

[0027] The middle part of the fixed frame 402 is in a hollow state, which is convenient for water to fall when the yarn segment 401 is twisted. The detection unit 4 also includes a detection groove 406 for storing water on the yarn segment 401 after twisting. The detection groove 406 is arranged at the bottom of the detection box 5. The water on the yarn segment 401 falls into the detection groove 406 through the hollow groove on the fixed frame 402 after twisting.

[0028] Lifting push rods 403 for lifting or lowering the fixing frame 402 are symmetrically provided on both sides of the bottom of the detection box 5. The lifting push rods 403 can be electric push rods or pneumatic push rods, etc.; a driving motor 410 is fixedly provided on the outer side of the right wall of the detection box 5, and the output shaft end of the driving motor 410 passes through the wall of the detection box 5 to the left, and a driving wheel 409 is provided in the box. The driving wheel 409 is meshed with the transmission wheel 408 when the detection unit 4 is in the detection box 5, that is, the driving wheel 409 and the transmission wheel 408 are both gears. When the detection unit 4 is lifted upward by the lifting push rod 403, the transmission wheel 408 is disengaged from the driving wheel 409.

[0029] The detection tank 406 contains a quantitative detection liquid. A first conductive member 503 and a second conductive member 504 for detecting the conductivity of the liquid therein are provided on both sides of the detection tank 406. The first conductive member 503 and the second conductive member 504 are connected to a conductivity meter, and the conductivity meter is connected to a PLC controller to feed back the conductivity to the PLC controller for observation by an operator. The detection liquid is a conductive liquid. When water enters the conductive liquid, the concentration of the liquid can be reduced, thereby reducing the conductivity of the liquid. That is, the change in the value fed back by the conductivity meter is converted into the amount of water added through the PLC controller.

[0030] A first pump body 505 for discharging the liquid in the detection tank 406 and a second pump body 506 for injecting the liquid into the tank are provided at the bottom of the detection tank 406. That is, after the conductive liquid in the detection tank 406 has been tested once, the liquid is discharged through the first pump body 505, and then the initial conductive liquid is quantitatively transported to the detection tank 406 through the second pump body 506 to prepare for the next test.

[0031] The detection box 5 is provided with a first hot air duct 501 and a second hot air duct 502 for hot air circulation on both sides; the drying box 3 is provided with a hot air blower 301 for injecting dry hot air therein, and the hot air blower 301 is connected to the first hot air duct 501 to synchronously convey hot air to the detection box 5, so that the yarn segment 401 on the detection unit 4 in the detection box 5 is dried by hot air after use, ensuring that the yarn is in a dry state before the next detection; preferably, the yarn segment 401 can be quickly replaced manually, and after the material of the sizing yarn is changed, the material of the yarn segment 401 needs to be replaced.

[0032] From the above, it can be seen that the water absorption of a single yarn segment is S, the number of yarn segments is M, and the conductivity meter feeds back the total moisture amount added to the detection tank 406 as I through the change in conductivity. It can be seen that the water absorption of the yarn in the steam box 1 is S=I / M. After inputting this formula into the PLC controller, the value of S can be intuitively obtained. Subsequently, by detecting or observing the S value, the amount of steam in the steam box can be manually adjusted.

[0033] In addition, the value of I can also be obtained by directly weighing the water content in the detection tank 406; that is, the detection tank 406 is suspended at the bottom of the detection box 5 through a hanging weighing sensor to obtain the value.

[0034] In this embodiment, each electrical component is connected to the PLC controller and is connected to the display of the sizing machine. Each parameter can be displayed on the display of the sizing machine, which is convenient for the operator to control and adjust.

[0035] A detection process for a yarn detection mechanism of a sizing machine, the process is as follows: S1: The continuous yarn enters the steam box 1 for wetting, then passes through the sizing tank 2 for sizing, and then enters the drying box 3 for drying to complete the sizing process; S2: The detection unit 4 enters the steam box 1 through the lifting push rod 403 to perform regular and frequent detection; S3: After the fixed frame 402 is placed in the steam box 1 for a period of time, the yarn segment 401 absorbs a certain amount of steam, and then the lifting push rod 403 drives the fixed frame 402 to descend and fall back into the detection box 5; S4: Then the transmission wheel 408 meshes with the driving wheel 409, and the driving motor 410 starts, so that the rotating disk 405 rotates relative to the sliding disk 404, so that each yarn segment 401 is twisted, and the water in the yarn segment is squeezed out and falls into the detection groove 406; S5: After the detection liquid in the detection tank 406 is mixed with water, the concentration is reduced, and the conductivity of the detection liquid is fed back to the controller through the first conductive element 503 and the second conductive element 504 to determine the water absorption amount of the yarn segment 401.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
