[0053] In a specific embodiment of the present invention, a heating element is provided inside the heating chamber 1 to provide a constant temperature condition to promote the evaporation of moisture in the cotton yarn. The heat dissipation holes 103 are used to achieve a ventilation effect, which is helpful for heat dissipation and prevents the heating chamber 1 from overheating. At the same time, internal air circulation is maintained to improve the drying efficiency. The mesh barrel 3 is located in the heating chamber 1 and is used to load the cotton yarn samples to be tested. The mesh structure is conducive to air circulation and accelerates the drying process. The cotton yarn is placed in the mesh barrel 3 and heated by the heating chamber 1 for testing. The four support legs 104 provide stable support to ensure that the device is placed stably to avoid tipping over. The support table 201 serves as the mounting base of the first cylinder 202 to provide a stable support for the entire lifting mechanism. Through the telescopic action, the lower plate 203 is driven to move up and down, thereby driving the entire lifting mechanism to rise or fall. The lower plate 203, the connecting column 204 and the upper plate 208 are designed as an integrated molding to ensure that they will not break during use. The lower plate 203 serves as a transition platform connecting the first cylinder 202 and the connecting column 204, ensuring the vertical movement of the connecting column 204 and playing a protective role. The connecting column 204 serves as a guide for the lifting movement to ensure the vertical stability of the mesh barrel 3 during lifting and lowering to avoid deviation. The upper plate 208 provides support for the mesh barrel 3 to ensure that it moves smoothly with the lifting mechanism. In this way, the mesh barrel 3 can be transported to the heating chamber 1. The mesh barrel 3 carries the cotton yarn sample and moves up and down under the action of the lifting mechanism, which is convenient for placing and taking out the sample. , the lifting and lowering of the mesh barrel can be accurately controlled to ensure that the cotton yarn sample is in a stable position in the heating chamber 1 without deviation, thereby ensuring the accuracy of the cotton yarn regain test and the safety of operation. The circular hole 205 allows the support column 207 to slide therein, providing a path for the lifting and lowering of the rotating mechanism. The servo motor 206 serves as a rotating power source, and drives the rotating disk 901 to rotate through the rotation of its output shaft. The support column 207 supports the servo motor 206. When the lifting support mechanism is working, it drives the servo motor 206 to rise and fall synchronously. The rotating disk 901 increases the fulcrum for the placement disk 904 and directly receives the power transmission of the servo motor 206. The mounting notch 902 provides a rotation center for the base 903 to ensure the stability of the rotation. The base 903 is converted into a rotating disk 901 rotates, and the placing plate 904, driven by the servo motor 206, realizes slow and stable rotation under the linkage of the base 903 and the installation slot 902, ensuring that the cotton yarn in the mesh barrel 3 is evenly dispersed, avoiding accumulation and flattening, ensuring that the cotton yarn can maintain a good loose state during the drying process, which is conducive to the uniform evaporation of water and improves the accuracy of the test results. At the same time, the combination of the rotating mechanism and the lifting support mechanism makes the loading, drying and taking out of the cotton yarn more convenient and safe. The second cylinder 501 provides thrust to drive the pressing plate to lightly press the cotton yarn to help control the moisture. The pressing plate, driven by the second cylinder 501, exerts slight pressure on the cotton yarn sample to help squeeze out excess moisture and prevent the cotton yarn from being over-compressed.When the pressure plate is lowered, the correction rod 510 cooperates with the hollow hook 505 to play a role of limiting and preventing the pressure plate from falling off, ensuring the correct position of the pressure plate. When the moisture is dried, the connecting circular plate 504 is dragged down by the third cylinder 503, so that the conical rod 506 enters the conical groove 507. When the conical rod 506 descends and contacts the abutment rod 508, the hollow hook 505 will rotate in an arc with the correction rod 510 as the center point. At this time, when the spring 509 abuts, the hollow hook The top of 505 will move outward, and the bottom will move inward. Under the support of the correction rod 510, it plays a role of limiting and preventing falling off, ensuring the stability of the hollow hook 505. The bottom of the hollow hook 505 has a hook. When the cotton yarn on the upper side of the placement plate 904 is dried, the hook moves inward and hangs on the bottom of the placement plate 904. The mesh barrel 3 is driven downward in cooperation with the lifting support mechanism. After waiting for the heat to dissipate, the cotton yarn can be directly taken out. When the third cylinder 503 is not working, During operation, the hollow hook 505 remains in a straight state, which does not affect the use of the pressing plate. When the third cylinder 503 is retracted, the spring 509 is reset and the abutment rod 508 is rebounded, so that the device can be restored to its original position. The clamping and taking-out mechanism can achieve light pressure on the cotton yarn sample to help remove excess moisture. At the same time, through the precise positioning and guiding mechanism, the stability and safety of the pressing plate during operation are ensured, and the damage of the cotton yarn during the test is effectively avoided, thereby improving the accuracy and efficiency of the test. The device realizes the slow rotation, lifting and clamping effect of the cotton yarn during drying through the lifting support mechanism, the rotating mechanism and the clamping and taking-out mechanism, so that when the cotton yarn is tested for moisture, human participation is avoided, and the labor consumption is reduced. The device has a high degree of automation and is suitable for the rapid and accurate measurement of the moisture regain of cotton yarn in laboratories and production lines. It not only improves the test efficiency, but also ensures the safety of operation and the accuracy of the results, providing effective automation for the quality control of textiles.

[0054] For details, please refer to Figure 1-Figure 7 A partition plate 4 is fixedly connected between the inner walls on both sides of the heating chamber 1, and the upper plate 208 is located inside the partition plate 4.

[0055] In this embodiment: the partition plate 4 increases the structural strength of the heating chamber 1 and ensures the uniformity of heating so that heat will not be dissipated. It can also guide the air and optimize the hot air circulation path so that the hot air can cover all parts of the mesh barrel 3 more evenly, thereby improving the drying efficiency and uniformity.

[0056] For details, please refer to Figure 1 The shapes of the mounting slot 902 and the base 903 are both hexagonal designs, which can ensure that they will not rotate during the matching activities.

[0057] In this embodiment: the hexagonal contact surface can provide more friction than the circular or other shapes, preventing sliding or rotation when subjected to torque. The hexagonal design can usually withstand greater torque and is not easily deformed or damaged, thereby increasing the service life of the component and the stability of the overall structure. When the hexagonal mounting slot 902 is matched with the base 903, which is also hexagonal, the contact area and pressure distribution are more even, which can effectively transmit and withstand torque and avoid loose connection or damage due to relative rotation during use.

[0058] For details, please refer to Figure 1-Figure 7 A groove 6 is provided on the circumferential surface of the mesh barrel 3, and a rubber strip 8 is fixedly connected to the lower end of the pressing plate.

[0059] In this embodiment: the groove 6 facilitates the hollow hook 505 to support and position when it rotates in an arc, and prevents the hollow hook 505 from shaking. The rubber strip 8 has good elasticity and shock-absorbing effects, and can absorb the impact generated when the pressure plate is pressed down to protect the cotton yarn from damage. When the rubber strip 8 contacts the cotton yarn, it can provide sufficient friction to prevent the cotton yarn from sliding under the action of the pressure plate, thereby ensuring the light pressing effect of the pressure plate. When the pressure plate is completely in contact with the mesh barrel 3, the rubber strip 8 can form a certain seal to reduce heat loss and improve drying efficiency.

[0060] For details, please refer to Figure 1-Figure 7 The opening of the heating chamber 1 is hinged with two door panels 101 through a hinge shaft, which is used to close the heating chamber 1 for use so that heat will not dissipate during the test. The surfaces of the two door panels 101 are provided with observation windows 102, and the material of the observation windows 102 is an acrylic plate, which is convenient for personnel to observe the situation inside the heating chamber 1 during the test.

[0061] In this embodiment: two door panels 101 are hinged to the opening of the heating chamber 1 through hinges. This design allows the door panels 101 to be easily opened and closed, which is convenient for loading and removing cotton yarn samples. At the same time, the door panels 101 are closed during the test to form a closed environment, ensuring the stability of the internal temperature of the heating chamber 1, avoiding heat loss, and improving energy efficiency. The observation window 102 is made of acrylic board material. The acrylic board has good transparency, weather resistance and high impact strength, and is suitable for observing the internal situation in a high temperature environment. Through the observation window 102, the operator can monitor the state of the cotton yarn inside the heating chamber 1 at any time during the test, without frequently opening the door panel 101, reducing heat loss and ensuring operational safety.

[0062] For details, please refer to Figure 1-Figure 7 A limiting clip 701 is provided at the upper end of the pressure plate, four mounting holes 702 are opened at the upper end of the limiting clip 701, and a hollow groove 703 is opened at the lower end of the connecting circular plate 504.

[0063] In this embodiment: the limiting clip 701 is used to limit the position of the abutment rod 508, ensuring that it moves along a predetermined path during operation, avoiding accidental displacement due to external force or vibration, ensuring the safety of the cotton yarn during processing and the accuracy of the test, and installing the bolt into the mounting hole 702 to ensure that the limiting clip 701 can be fixed and will not loosen or fall off during use. When the connecting circular plate 504 descends, the limiting clip 701 will enter the hollow groove 703, which will not hinder the use of the connecting circular plate 504.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
