Description

Technical Field

[0001] The invention relates to the technical field of gauze winding and slitting, in particular to a gauze automatic winding and slitting device and a method thereof. Background Art

[0002] Gauze automatic winding and slitting equipment is an automated machine used in medical, industrial and other fields, mainly used for winding and slitting gauze.

[0003] In the field of gauze roll slitting technology, screws are currently commonly used to fasten the cutting knife on the slitting equipment. However, in long-term actual production, the cutting knife often appears skewed due to the vibration generated by the continuous operation of the slitting equipment and the complex and changeable forces that the cutting knife bears during cutting; the skewed cutting knife cannot cut the gauze roll along the predetermined straight line trajectory, which generates additional resistance and friction, which will increase the energy consumption of the cutting equipment, reduce the cutting speed, extend the cutting time of a single roll, and significantly reduce the overall cutting efficiency; at the same time, it will cause uneven cutting force, and when cutting a thick gauze layer, one side will be broken while the other side is not, which increases the probability of gauze getting stuck in the equipment and hinders the continuity of cutting; and for the tool itself, the contact angle between the blade and the gauze and the force mode change, causing local excessive extrusion and friction, accelerated blade wear, and severe parts will quickly The blade is rolled or broken, and the long-term skewness gradually deforms the blade structure, such as bending and twisting, which not only deteriorates the cutting effect but also increases the maintenance cost and difficulty. In terms of product quality, the cutting size accuracy decreases, the setting width or length deviates, the number of products that do not meet the size requirements increases, and the scrap rate increases. The quality of the cutting edge deteriorates, and defects such as unevenness, burrs, and serrations appear. When medical gauze is used to bandage wounds, the burrs will irritate the wound and cause discomfort or even infection. The uneven edges of industrial wiping gauze will scratch the surface of the wiped object, affecting the wiping effect and the quality of the object. Unfortunately, the existing technology lacks effective means to detect the skew of the tool, and it cannot be discovered and corrected in time, which greatly limits the development and application of gauze roll slitting technology.

[0004] In addition, the temperature and humidity differences in the working environment of the equipment cause the humidity of the gauze rolls being cut to be different, which also brings a series of problems to the cutting knife; when the moisture content of the gauze is too high, its texture is soft and sticky. During the cutting process, a large amount of fiber threads will adhere to the blade surface, just like wet noodles sticking to kitchen utensils, which gradually reduces the effective cutting part of the cutting knife, and the cutting force decreases accordingly, and the cutting effect is seriously deteriorated; for metal cutting knives, the moisture in the gauze, especially the moisture containing salt or other corrosive substances, will cause the cutting knife to rust and corrode; the blade surface becomes rough after rust and corrosion, and the blade edge is also damaged, which not only affects the cutting quality, but also leaves rust on the gauze, causing gauze pollution; and when the moisture content of the gauze is too low, the fiber threads become brittle and hard. When the cutting knife cuts in, the brittle and hard gauze may suddenly break, exerting a large impact force on the cutting edge of the cutting knife, resulting in blade chipping; blade chipping will make the cutting surface discontinuous, produce uncut parts or cause scratches on the gauze surface.

[0005] Therefore, the present invention proposes a gauze automatic winding and slitting device to solve the above problems. Summary of the invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a gauze automatic winding and slitting device and method thereof to solve the problems existing in the prior art.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a gauze automatic winding and slitting device and method thereof, comprising: a main frame, a transverse moving plate, a conveying member, a gauze roll, an external moving member, and a slitting knife, wherein the transverse moving plate is slidably connected to the main frame through a track, the gauze roll is conveyed by the conveying member fixedly connected to the transverse moving plate, the external moving member is arranged on one side of the main frame, and the external moving member is located below the main frame, and further comprising: an offset detection self-correction component and a knife surface maintenance component, wherein the knife surface maintenance component is located above the offset detection self-correction component;

[0016] The automatic winding and slitting method of gauze comprises the following steps: material pretreatment and feeding preparation, roll transfer, slitting operation steps, comprehensive quality inspection and finished product finishing;

[0017] The material pretreatment and feeding preparation include: after removing the debris and visible fiber threads on the gauze roll, using a high-precision sensor to identify the initial position of the roll, and combining a fastening mechanism to firmly lock the gauze roll to prevent feeding deviation;

[0018] The winding process includes: driving the winding motor to operate, activating the tension adjustment module, dynamically adjusting the speed of the winding motor according to the preset tension threshold and real-time monitoring data; and guiding the gauze to be wound smoothly and orderly with the help of the friction between the gauze surfaces and the auxiliary shaft rod;

[0019] The roll transfer includes: when the winding task is completed or the set parameters are reached, a transfer signal is automatically generated, the winding operation is suspended, and a special transfer mechanism, i.e., a Velcro conveyor belt, is activated to safely transfer the gauze roll to the slitting area;

[0020] The slitting operation steps include: the slitting device is started after receiving a signal, the conveying member conveys the gauze roll to the cutting area, and the slitting knife slits at a constant speed according to a preset path; during the cutting process, when the slitting knife is skewed, the electrical contact A and the electrical contact B are no longer in contact, and the device master controller that is electrically connected to the electrical contact A and the electrical contact B will control the air pump connected to the air pipe A to work, and calibrate the cavity to fill gas, so as to push the deflected electrical contact B to the initial state, so as to perform self-calibration of the slitting knife;

[0021] The blade surface maintenance component is turned on simultaneously. The blade surface maintenance component collects the fiber threads on the slitting knife through the collection cavity, and the grinding block grinds the cutting surface of the slitting knife.

[0022] The comprehensive quality inspection and finished product sorting include: the gauze rolls after slitting enter the multi-dimensional quality inspection link, and the gauze quality is determined by comprehensive use of visual imaging and physical performance testing technology.

[0023] Unqualified gauze rolls are accurately marked and classified, transported to a specific defective product processing area, and the causes are thoroughly analyzed and recorded.

[0024] Compared with the prior art, the present invention provides a gauze automatic winding and slitting device, which has the following beneficial effects:

[0025] 1. The present invention shows excellent performance advantages in the cutting process through the design of the N-shaped shape, and the synergy of the calibration sheet and the gas in the calibration chamber; when the slitting knife blade is curled, notched or blunted, but the cutting work of the slitting knife and the gauze roll is still in progress, the auxiliary design can effectively buffer the forced cutting action of the slitting knife on the gauze roll; this buffering mechanism greatly reduces the risk of tool breakage and ensures the continuity and stability of the cutting work; different from the traditional cutting device, when the tool is damaged, it often causes frequent tool damage due to the inability to buffer the cutting force in time, which not only requires frequent tool replacement, increases production costs and downtime, but also seriously affects production efficiency; the present invention can effectively avoid such problems, significantly extend the service life of the tool, reduce the number of production interruptions caused by tool failure, and make the production process smoother and more efficient;

[0026] In addition, the design also improves the reliability and adaptability of the entire cutting system; whether it is dealing with cutting objects of different materials, thicknesses or humidity, or in a complex and changeable working environment, the present invention can always maintain a good working state with its effective buffer mechanism and stable cutting performance; this provides enterprises with a more flexible and reliable cutting solution under different production needs and conditions.

[0027] 2. The present invention adopts the design of the offset detection self-correction component. First, in terms of cutting accuracy and product quality, the traditional screw fastening method is difficult to deal with the problem of slitting knife skew caused by various factors during the cutting process, while the present component can automatically detect the state of the slitting knife in real time. Once the skew is detected, it is immediately corrected indirectly through gas. This ensures that the slitting knife always cuts the gauze roll along the precise predetermined trajectory, effectively avoiding the cutting size deviation caused by the skew of the cutting knife, such as uneven width or length, greatly reducing the scrap rate; and the edge quality of the cut gauze is significantly improved, and there are no more uneven, burred, and jagged defects caused by the skew. Whether it is the safety of medical gauze for wound dressing or the protection of the surface of the wiped object by industrial wiping gauze, it has been effectively guaranteed, greatly improving the overall quality of the product, so that it can better meet the market's strict requirements for high quality of gauze products;

[0028] Secondly, in terms of cutting efficiency; since this component can automatically correct the skew of the slitting knife in time, the cutting process will no longer have additional resistance, friction and cutting interruption problems due to the skew of the knife, thus ensuring a stable and efficient cutting speed; avoiding frequent shutdowns for inspection and adjustment, greatly shortening the cutting time of a single gauze roll, and significantly improving the overall cutting efficiency; from the perspective of the tool's service life and maintenance cost; unlike the traditional screw fastening method, the slitting knife is skewed, the blade is subjected to uneven force and wears faster, and is prone to curling, chipping and even deformation of the knife body, greatly shortening the tool life and increasing the difficulty and cost of maintenance.

[0029] 3. The present invention can bring the following benefits by designing that the collecting chamber and the grinding block can be clamped on the slitting knife for up and down movement: in terms of tool maintenance, the grinding block can effectively grind the cutting blade surface of the slitting knife during the up and down movement, greatly reducing the probability of blade curling and blunting, extending the service life of the tool, reducing the frequency of tool replacement, thereby reducing the tool procurement cost and the downtime loss caused by tool replacement, and improving the continuity and economy of production;

[0030] In the fiber thread processing, it can scrape off the fiber threads adhering to the slitting knife when it moves up and down; this not only keeps the cutting knife surface clean, so that the slitting knife can continue to cut in the best state, improving the cutting efficiency, but also provides a powerful aid for the subsequent collection of fiber threads by suction transfer; through the above method, the accumulation of fiber threads in the cutting area is avoided, the problem of uneven cutting surface and gauze stratification caused by residual fiber threads is reduced, and the stability and reliability of product quality are further guaranteed;

[0031] From the perspective of tool correction, this linear up and down movement can shape the slitting knife during the cutting process; it can effectively prevent the upper and lower fastening ends of the slitting knife from being in a vertical state, while the cutting part is twisted and skewed during long-term cutting due to the influence of the gauze roll; this makes the cutting process more precise and stable, significantly improves the stability of the slitting knife in slitting the gauze roll, and ensures the consistency and accuracy of the cutting size.

[0032] 4. The present invention is based on the speed feedback of the speed sensor and combines the amount of fiber threads collected in the collection cavity per unit time to indirectly judge the quality of the gauze roll, which has many significant beneficial effects;

[0033] First, in terms of quality inspection and monitoring, this innovative inspection method provides an efficient, convenient and non-invasive means for the quality assessment of gauze rolls; traditional gauze quality inspection often requires complex equipment and cumbersome processes, while the present invention can simultaneously monitor quality during the cutting process, greatly improving the inspection efficiency and saving special quality inspection time and labor costs; by real-time observation of the accumulation of fiber threads in the cavity per unit time, the producer can quickly and intuitively understand the quality status of the current batch of gauze rolls, timely discover quality fluctuations and make corresponding adjustments, effectively avoiding product defects and production losses caused by the use of low-quality gauze;

[0034] Secondly, for the optimization of the production process, this detection mechanism can provide accurate data support for the adjustment of the production process. When the abnormal accumulation of fiber threads is found, indicating that there is a problem with the quality of the gauze roll, the producer can trace the problem to the raw material supply and production environment control based on this feedback information; for example, if it is determined that the abnormal moisture content of the gauze causes an increase in the shedding of fiber threads, the drying or humidification process parameters can be adjusted in time to ensure the stability of the quality of the gauze produced subsequently; this kind of production process optimization based on real-time data helps to improve the stability and reliability of the entire production system, reduce the scrap rate caused by unstable quality, improve production efficiency, and reduce production costs.

[0035] 5. The present invention brings about multi-faceted effect improvement for the cutting device through the design of the blade maintenance component; in terms of cutting stability and accuracy, its precise shape correction effectively overcomes the problem of easy deflection of the blade in traditional cutting, ensures the accuracy of the cutting trajectory, greatly improves the dimensional accuracy and qualified rate of the product, and meets the stringent requirements of high-end applications for cutting quality; in the field of tool maintenance, the grinding function continuously keeps the tool sharp, effectively reduces the curling and blunting of the blade, significantly extends the service life of the tool, and reduces the replacement frequency, thereby reducing the time loss caused by tool downtime and the tool procurement cost, and improving the economy and operation efficiency of the production equipment; for the problem of fiber threads, the component relies on its efficient collection and transfer capabilities to ensure that the blade surface is always in a clean state, eliminating the interference of fiber thread residues on cutting, It effectively maintains the stability and consistency of cutting quality and avoids the adverse effects of uneven cutting force caused by fiber attachment. Furthermore, considering the impact of temperature and humidity differences in the equipment's working environment on the cutting knife, this component can effectively prevent fiber threads from adhering to the knife surface in large quantities due to the high moisture content of the gauze in a high humidity environment, thereby avoiding a decrease in cutting force and a deterioration in cutting effect, while reducing the risk of rust and corrosion of metal knives and preventing rust from contaminating the gauze. In a low humidity environment, it can buffer the impact of brittle gauze on the blade, reduce the probability of blade chipping, and avoid discontinuities in the cutting surface and scratches on the gauze surface. From the perspective of overall production process optimization, this component integrates a variety of key functions, which greatly reduces production interruptions caused by poor tool condition, fiber thread interference, and temperature and humidity factors, and enhances the continuity and fluency of production.

[0070] For further examples, please refer to Figure 3 , Figure 5 , Figure 6 , Figures 9 to 13 As shown:

[0071] The blade surface maintenance component 8 is used to polish and maintain the surface of the slitting knife 6, and to transfer the gauze fiber filaments during the cutting process of the gauze roll 4;

[0073] in:

[0074] The blade surface maintenance component 8 is used to polish and maintain the surface of the slitting knife 6 and to transfer the gauze fiber filaments during the cutting process of the gauze roll 4.

[0075] The air pipe B803 is connected to an external air pump, and there is an electrical connection between the air pump and the main controller of the device.

[0076] The moving strip 804 is slidably matched with the air cavity strip 802 .

[0077] The collecting cavity 805 is mainly used to collect fiber threads and debris generated when the slitting knife 6 cuts the gauze roll 4, so as to prevent the slitting knife 6 with fiber threads from affecting the cutting work of the gauze roll 4.

[0078] The partition 807 is mainly used to block the influence of the fiber threads in the collection cavity 805 on the corresponding air pump.

[0079] The grinding block 808 is mainly used for grinding the cutting surface of the slitting knife 6 to prevent the blade from becoming blunt during cutting, and the inner side of the grinding block 808 is not always in close contact with the cutting surface of the slitting knife 6. The grinding stone on the inner side of the grinding block 808 can be moved closer to and away from the cutting surface of the slitting knife 6 through pneumatic control. In the non-grinding stage, there is a certain distance between the grinding stone on the inner side of the grinding block 808 and the slitting knife 6.

[0084] The quality of the gauze roll 4 in this unit time is indirectly judged by the speed feedback of the speed sensor 812 and the amount of fiber threads collected in the collecting cavity 805 in this unit time; that is, if the quality is good and the water content is moderate, fewer fiber threads will fall off, otherwise the quality of the gauze roll 4 is poor.

[0085] Further examples:

[0086] The automatic winding and slitting method of gauze comprises the following steps: material pretreatment and feeding preparation, roll transfer, slitting operation steps, comprehensive quality inspection and finished product finishing;

[0087] Material pretreatment and feeding preparation include: after removing the debris and visible fiber threads on the gauze roll 4, using a high-precision sensor to identify the initial position of the roll, and combining a fastening mechanism to firmly lock the gauze roll 4 to prevent feeding deviation;

[0088] The winding process includes: driving the winding motor to operate, activating the tension adjustment module, dynamically adjusting the speed of the winding motor according to the preset tension threshold and real-time monitoring data; and guiding the gauze to be wound smoothly and orderly with the help of the friction between the gauze surfaces and the auxiliary shaft;

[0089] The roll transfer includes: when the winding task is completed or the set parameters are reached, a transfer signal is automatically generated, the winding operation is suspended, and a special transfer mechanism, i.e., a Velcro conveyor belt, is activated to safely transfer the gauze roll 4 to the slitting area;

[0090] The slitting operation steps include: the slitting device is started after receiving the signal, the conveying member 3 conveys the gauze roll 4 to the cutting area, and the slitting knife 6 slits at a constant speed according to the preset path; during the cutting process, when the slitting knife 6 is skewed, the electrical contact A703 and the electrical contact B708 ​​are no longer in contact, and the device master controller that is electrically connected to the electrical contact A703 and the electrical contact B708 ​​will control the air pump connected to the air pipe A705 to work, and fill the calibration cavity 704 with gas, so as to push the deflected electrical contact B708 ​​to the initial state, so as to perform the self-calibration work of the slitting knife 6;

[0091] The blade surface maintenance component 8 is simultaneously turned on. The blade surface maintenance component 8 collects the fiber threads on the slitting knife 6 through the collecting cavity 805, and the grinding block 808 grinds the cutting surface of the slitting knife 6.

[0092] Comprehensive quality inspection and finished product sorting include: the gauze rolls 4 after slitting enter the multi-dimensional quality inspection link, and the gauze quality is determined by comprehensive use of visual imaging and physical performance testing technology. The qualified gauze rolls 4 are neatly stacked in the finished product storage area by the intelligent handling robot according to the predetermined layout, which is convenient for subsequent packaging;

[0093] The unqualified gauze rolls 4 are accurately marked and classified, transported to a specific defective product processing area, and the causes are thoroughly analyzed and recorded.

[0094] Everything in the above example works like this:

[0095] In the initial state:

[0096] The electrical contact B708 ​​is in contact with the magnet 710, the slitting knife 6 is attracted by the magnet 710, the N-shaped piece 711 is not deformed, the moving bar 804 does not extend from the air cavity bar 802, and the eddy current piece 811 does not rotate.

[0097] After the gauze roll 4 is transported into the transport member 3 via the external transport device, the transport member 3 will further intermittently transport the gauze roll 4 to the position where the outward moving member 5 is located, and after the transport, the transverse moving plate 2 will reciprocate with the main frame 1 under the action of the bottom end drive, and during this reciprocating movement, the slitting knife 6 provided at the bottom of the outward moving member 5 will cut the transported gauze roll 4;

[0098] The following is the working process of the offset detection self-correction component 7:

[0099] Furthermore, during the slitting process of the gauze roll 4 by the slitting knife 6, if the slitting knife 6 is skewed, that is, it is no longer perpendicular to the gauze roll 4 for slitting, please refer to the attached Figure 7 To Attachment Fig. 9 At this time, since the slitting knife 6 is skewed, that is, it rotates relative to the sliding block 702, the slitting knife 6 will rotate the calibration plate 707 fixedly connected to the rotating column 706 with the assistance of the embedded column 709 and the rotating column 706. As the calibration plate 707 rotates, the electrical contact B708 ​​on the calibration plate 707 is no longer in contact with the electrical contact A703 on the inner cavity wall of the sliding block 702. At this time, the device master controller that is electrically connected to the electrical contacts A703 and B708 ​​will control the air pump connected to the air pipe A705 to work. At this time, the air pump will fill the calibration cavity 704 with gas through the air pipe A705, so as to push the deflected electrical contact B708 ​​to the initial state. At this time, the slitting knife 6 indirectly connected to the rotating column 706 is restored to a non-skewed qualified state;

[0100] Furthermore, when the blade of the slitting knife 6 is curled, notched or blunted, but the gauze roll 4 is still being slit, during each slitting process, due to the increased cutting resistance, the slitting knife 6 located in the embedded column 709 will be forced to move backward, and the N-shaped part 711 located on one side will be compressed and deformed, thereby buffering the force caused by its cutting; in addition, if the cutting resistance is large, the slitting knife 6 is about to tilt, and the embedded column 709 will deflect in the calibration chamber 704 with the calibration piece 707 through the rotating column 706, and the gas in the calibration chamber 704 can also be used as a buffer medium at this time, that is, through the design of the shape of the N-shaped part 711, and the synergistic effect of the calibration piece 707 and the gas in the calibration chamber 704, excellent cutting performance is exhibited during the cutting process. performance advantage; when the blade of the slitting knife 6 is curled, notched or blunted, but the cutting work of the slitting knife 6 and the gauze roll 4 is still in progress, the auxiliary design can effectively buffer the forced cutting action of the slitting knife 6 on the gauze roll 4; this buffer mechanism greatly reduces the risk of the tool breaking, and ensures the continuity and stability of the cutting work; different from the traditional cutting device, when the tool is damaged, it often causes the tool to be damaged frequently due to the inability to buffer the cutting force in time, which not only requires frequent replacement of the tool, increases production costs and downtime, but also seriously affects production efficiency; the present invention can effectively avoid such problems, significantly extend the service life of the tool, reduce the number of production interruptions caused by tool failure, and make the production process smoother and more efficient;

[0101] In addition, the design also improves the reliability and adaptability of the entire cutting system; whether dealing with cutting objects of different materials, thicknesses or humidity, or in complex and changing working environments, the present invention can always maintain a good working state with its effective buffer mechanism and stable cutting performance;

[0102] Please refer to the above working process Figures 1 to 9 .

[0103] The following is the working process of the blade surface maintenance component 8:

[0104] Furthermore, the reciprocating movement of the moving strip 804 in the air cavity strip 802 per unit time can be adjusted by intervention of the control system. Specifically, when in use, the air pipe C810 performs suction through the air pump, and the moving strip 804 in the air cavity strip 802 can move up and down during the suction of the air pump at one end of the air pipe B803; hereby, the moving strip 804 can drive the collection cavity 805 and the grinding block 808 on the collection cavity 805 to move up and down on the cutting surface of the slitting knife 6, and during the up and down movement of the grinding block 808 The grinding stone on the inner side of the grinding block 808 can grind the cutting blade surface of the slitting knife 6, and at the same time, the moving grinding block 808 can hang the fiber threads on the slitting knife 6 into its own inner cavity, and transfer them to the collection cavity 805 through the oblique strip 809 under the suction of the air pump on the air pipe C810. At this time, the partition 807 serves as a safety auxiliary for the suction pump to prevent the fiber threads from entering the suction pump through the air pipe C810. Further, the fiber threads in the collection cavity 805 can be processed regularly according to the usage;

[0105] Furthermore, when the suction pump connected to the air pipe C810 indirectly assists the collection chamber 805 in collecting the fiber threads, the vortex member 811 fixedly connected to the air pipe C810 by the support rod will rotate with the flow of gas during the suction, and during this rotation, the speed sensor 812 thereon will record its rotation speed; it should be noted that when more fiber threads are collected in the collection chamber 805, the gas flow rate passing through the vortex member 811 will slow down;

[0106] Furthermore, by designing that the collecting chamber 805 and the grinding block 808 can be clamped on the slitting knife 6 and move up and down, the following benefits can be brought about: in terms of tool maintenance, the grinding block 808 can effectively grind the cutting blade surface of the slitting knife 6 during the up and down movement, which greatly reduces the probability of blade curling and blunting, prolongs the service life of the tool, reduces the frequency of tool replacement, thereby reducing the tool procurement cost and the downtime loss caused by tool replacement, and improves the continuity and economy of production;

[0107] During the fiber thread processing, the fiber threads adhering to the slitting knife 6 can be scraped off when it moves up and down; this not only keeps the cutting blade clean, so that the slitting knife 6 can continue to cut in the best state, improving the cutting efficiency, but also provides a powerful aid for the subsequent collection of fiber threads transferred by suction; through the above method, the accumulation of fiber threads in the cutting area is avoided, the problem of uneven cutting surface and gauze stratification caused by residual fiber threads is reduced, and the stability and reliability of product quality are further guaranteed;

[0108] From the perspective of tool correction, this linear up and down movement can shape the slitting knife 6 during the cutting process; it can effectively avoid the upper and lower fastening ends of the slitting knife 6 being in a vertical state, and the cutting part being twisted and skewed during long-term cutting due to the influence of the gauze roll 4; this makes the cutting process more precise and stable, significantly improves the stability of the slitting work of the slitting knife 6 on the gauze roll 4, and ensures the consistency and accuracy requirements of the cutting size.

[0109] Furthermore, based on the speed feedback of the speed sensor 812 and in combination with the amount of fiber threads collected in the collecting cavity 805 per unit time, the quality of the gauze roll 4 is indirectly judged, which has many significant beneficial effects;

[0110] First, in terms of quality inspection and monitoring, this innovative inspection method provides an efficient, convenient and non-invasive means for quality assessment of the gauze roll 4; traditional gauze quality inspection often requires complex equipment and cumbersome processes, while the present invention can simultaneously monitor quality during the cutting process, greatly improving the inspection efficiency and saving special quality inspection time and labor costs; by real-time observation of the accumulation of fiber threads in the cavity 805 collected per unit time, the producer can quickly and intuitively understand the quality status of the current batch of gauze rolls 4, discover quality fluctuations in time and make corresponding adjustments, effectively avoiding product defects and production losses caused by the use of low-quality gauze;

[0111] Secondly, for the optimization of the production process, this detection mechanism can provide accurate data support for the adjustment of the production process. When the abnormal accumulation of fiber threads is found, indicating that there is a problem with the quality of the gauze roll 4, the producer can trace the problems in the raw material supply and production environment control based on this feedback information; for example, if it is determined that the abnormal moisture content of the gauze causes an increase in the shedding of fiber threads, the drying or humidification process parameters can be adjusted in time to ensure the stability of the quality of the gauze produced subsequently; this kind of production process optimization based on real-time data helps to improve the stability and reliability of the entire production system, reduce the scrap rate caused by unstable quality, improve production efficiency, and reduce production costs.
