Description

Technical Field

[0001] The present invention relates to the technical field of continuous drying, in particular to a drying device for continuous underwear webbing. Background Art

[0002] In modern industrial production, continuous conveying and drying devices play a key role in many fields, especially in the underwear webbing production industry, where an efficient and stable drying process is crucial to product quality and production efficiency.

[0003] Existing equipment often uses multiple motors and sleeved pulleys for transmission. The existing belt and pulley transmission will generate high temperatures due to the continuous conveying and drying device. Since the material properties of the belt will change under high temperature, the existing continuous conveying and drying device mostly uses pulley transmission. In addition, high temperature baking can easily cause the elasticity of the belt material to decrease and plastic deformation, resulting in unstable transmission and poor reliability. This can easily lead to low transmission efficiency and inaccurate speed control. Belt transmission has the disadvantages of large kinetic energy loss and low transmission efficiency. It is difficult to meet the high-precision control requirements of the driving shaft speed, affecting the conveying efficiency.

[0004] During the drying process, only maintaining the pre-set drying temperature can easily lead to insufficient drying, excessive residual moisture in the ribbon, and easy mold and deterioration; or too high a temperature can cause the ribbon to over-dry and become hard and brittle, which also affects product quality. In addition, if the conveyor belt is in a high temperature environment for a long time, it will accelerate its aging speed.

[0005] Therefore, the above problems need to be solved. Summary of the Invention

During this process, the instrument will record in real time how the sample's deformation changes with temperature under stress, and draw a thermomechanical curve based on the detected change data; observe the thermomechanical curve. When the slope of the corresponding thermomechanical curve segment is greater than the preset slope threshold, it is determined that the deformation of the ribbon sample has changed dramatically, indicating that the ribbon material begins to lose its original stable mechanical properties due to thermal effects at this temperature.

During the heating process, the thermogravimetric analyzer records the change of sample mass with temperature in real time and generates a thermogravimetric curve. Observe the thermogravimetric curve. When the slope of the corresponding thermogravimetric curve segment is greater than the preset slope threshold, or the rate of decrease of the ribbon sample mass exceeds the preset rate of decrease threshold, the corresponding temperature data is recorded as the second thermal stability critical temperature.

At the same time, such a transmission structure avoids the problems of elasticity reduction and plastic deformation of the belt material caused by high temperature in traditional pulley transmission, ensuring the stability and reliability of transmission in a high-temperature drying environment, and then through the meshing cooperation of the small gear and the large gear, it is easy to realize reversal and adjust the transmission direction, thereby realizing continuous transportation of multi-layer serpentine transmission belts and improving transmission efficiency. The stability and flexibility of the conveyor belt operation meet different production needs. The cooperation of the multi-layer serpentine conveyor belt and the serpentine heating tubes on both sides prolongs the heating time of the belt and increases the contact area, thereby improving the drying efficiency and achieving the function of uniform and efficient drying. The cooperation of the vacuum pump and the condensation water tank facilitates the real-time extraction of high-temperature moisture, reduces the humidity in the cabinet, improves the stability of the equipment operation, and prevents the high temperature and moisture from accelerating the aging of the transmission components. Ultimately, it solves the problem of traditional pulley transmission that high temperature causes belt deformation, resulting in reduced strength and elasticity, which shortens the belt's service life. At the same time, it improves the drying uniformity and production efficiency, and realizes the long-term stable operation of the transmission system.

[0042] The cabinet 1 of the drying device is provided with a controller, and a transmission module, an analysis module and an execution module are provided inside the controller;

[0043] The density of the webbing is obtained based on the material of the webbing. The thickness of the webbing is obtained by installing two laser displacement sensors symmetrically above and below the webbing. The drying speed and initial moisture content of the webbing are respectively obtained using multiple infrared moisture sensors and capacitive moisture sensors installed on the cabinet 1. The air velocity inside the cabinet 1 is obtained using a wind speed sensor. The heat capacity of the cabinet is calculated using the heat capacity calculation formula (heat capacity = mass × specific heat capacity) based on the specific heat capacity corresponding to the material composition of the cabinet 1, combined with the cabinet's mass and structural dimensions.

[0044] A ribbon sample is selected and fixed on the sample stage of the thermomechanical analyzer. A set pressure is applied to the sample, and then the heating program is started. The temperature is increased at the set heating rate. During this process, the instrument will record in real time how the sample's deformation changes with temperature under stress. A thermomechanical curve is drawn based on the detected change data. The thermomechanical curve is observed. When the slope of the corresponding thermomechanical curve segment is greater than the preset slope threshold, it is determined that the deformation of the ribbon sample has changed dramatically, indicating that the ribbon material begins to lose its original stable mechanical properties due to thermal effects at this temperature. The corresponding temperature data at this time is recorded as the thermal stability critical temperature 1.

[0045] A set amount of ribbon sample is selected and cut into small pieces of equal size to ensure uniform heating. The small pieces of ribbon sample are then placed in the sample crucible of the thermogravimetric analyzer. The heating program is started, and the temperature is gradually increased from room temperature at a set heating rate. During the heating process, the thermogravimetric analyzer records the change in sample mass with temperature in real time and generates a thermogravimetric curve. The thermogravimetric curve is observed. When the slope of the corresponding thermogravimetric curve segment is greater than a preset slope threshold, or the rate of decrease in the ribbon sample mass exceeds a preset rate of decrease threshold, the corresponding temperature data is recorded as the second thermal stability critical temperature.

[0046] Compare the thermal stability critical temperature 1 with the thermal stability critical temperature 2. If the absolute value of the difference between the two is less than the preset difference threshold, the detected temperature data is determined to be accurate, and the average of the thermal stability critical temperature 1 and the thermal stability critical temperature 2 is used as the thermal stability critical temperature data. Otherwise, it is determined that the detected temperature data are significantly different and the test is repeated.

[0047] The outer contour of the ribbon is used as the basic frame, and the basic frame is reduced inward multiple times with a set ratio to obtain multiple reduced frames. The perimeter of the reduced frame is segmented with a set length, and collection points are set at the segment positions. The ribbon moisture content data of the collection points are collected, and the average of the multiple moisture content data collected is calculated. and standard deviation Calculation of the mean value and standard deviation Set the fluctuation range of moisture content data. The fluctuation range is , determine the moisture content data that is not within the fluctuation range as an abnormal value, remove the abnormal value, calculate the mean of the remaining moisture content data, and use the mean of the remaining moisture content data as the initial moisture content data of the ribbon ;

[0048] Suitable drying temperature and initial moisture content of the webbing The relationship between , is the preset coefficient related to the initial moisture content of the webbing; considering the air flow rate data inside cabinet 1 and heat capacity data Suitable drying temperature The appropriate drying temperature formula is adjusted to , is a preset coefficient related to air velocity, is a preset coefficient related to heat capacity; taking into account the thickness of the webbing data , ribbon material density data and drying speed data Suitable drying temperature The appropriate drying temperature formula is adjusted to , is a preset coefficient related to the webbing thickness and webbing density, is a preset coefficient related to the drying speed;

[0049] From the perspective of chemical reaction kinetics, the aging process of many materials can be approximately regarded as a chemical reaction process, and its reaction rate (corresponding to the aging rate of the conveyor belt) usually follows the Arrhenius equation, that is, the reaction rate constant and temperature relationship satisfaction , is the basic rate of aging reaction without considering the effect of temperature, is the activation energy, is the gas constant; in practical applications, below a certain minimum temperature When the material ages very slowly, it can be almost ignored; and when the temperature is above a certain maximum When , the aging rate will increase sharply and may exceed the scope of the conventional aging model, so the step function is introduced To correct the function , after correction, we get When the conveyor belt is in a high temperature environment for a long time, aging is often a cumulative process. That is, as time goes by, even if the temperature remains unchanged, the aging degree will continue to deepen. Therefore, a time-related Related accumulation factors , is the preset cumulative damage speed coefficient; after further correction, we get ;

[0051] In summary, the most suitable drying temperature and satisfy , get the most suitable drying temperature After that, a temperature control signal is generated and transmitted to the execution module.

[0052] Working principle: When the present invention is used, the underwear ribbon to be dried is first lifted to the top of the cabinet 1 by the elevator 2. The elevator 2 continuously and stably feeds the ribbon into the cabinet 1. The first motor 5 starts to work, and its output shaft drives the first transmission rod 7 coaxially fixed thereto to rotate. The multiple first cylindrical cams 8 on the first transmission rod 7 rotate accordingly. The first cylindrical cams 8 are rollingly connected with the multiple first rollers 9. Since the first rollers 9 are arranged in a ring shape with equal distances along the top surface of the first turntable 10 and the bottom ends are fixed to the first turntable 10, the rotation of the first cylindrical cam 8 causes the first rollers 9 rolls, thereby driving the first turntable 10 to do circular motion. At the same time, the small gear at the bottom of the first transmission rod 7 meshes with the large gear 6, and the large gear 6 drives the coaxially fixed second transmission rod to rotate. The multiple second cylindrical cams 11 on the second transmission rod rotate, and the second cylindrical cams 11 are rollingly connected with the multiple second rollers. The second turntable fixed to the bottom end of the second roller also rotates accordingly. The first turntable 10 and the second turntable are coaxially fixed with a transmission belt driving shaft 12. Driven by them, the transmission belt driving shaft 12 rotates, and the transmission belt driving shaft 12 is connected to the horizontal device located on one side of the cabinet 1. The driven shafts installed in the cabinet 1 work together to drive the conveyor belt installed between them to operate. The conveyor belt adopts a multi-layer flat serpentine arrangement, so that the webbing can be transported in the cabinet 1 according to the preset route. When the webbing moves with the conveyor belt in the cabinet 1, the heating tubes symmetrically arranged on both sides of the inner wall of the cabinet 1 and arranged in a serpentine shape start to work. The heating tubes emit a large amount of heat, forming a high-temperature drying environment inside the cabinet 1. The webbing is in full contact with the heating tubes during the transmission process. The heat emitted by the heating tubes gradually penetrates into the interior of the webbing, evaporating the moisture in the webbing. , to achieve drying of the ribbon. During the drying process, the moisture in the ribbon continuously evaporates to form water vapor. At this time, the exhaust fan 4 is started, and the gas containing water vapor in the cabinet 1 is directly extracted and discharged to the outside of the device through the suction pipe connected to the inner wall of the condensed water tank 3. In this way, the humidity in the cabinet 1 can be reduced in time, and the accumulation of water vapor in the cabinet 1 can be avoided, ensuring that the drying process can be carried out continuously and efficiently. The dried ribbon is transported to the exit position of the cabinet 1 along the conveyor belt, completing the entire drying process, and finally output from the device as a finished product. At this point, the device is complete.
