Description

Technical Field

[0001] This application relates to the technical field of fire glove sewing, and in particular to a method, system, terminal and storage medium for controlling the sewing tension of fire gloves. Background Technology

[0002] The method of controlling the sewing tension of firefighting gloves refers to the process of adjusting the tension of the sewing thread during sewing based on the characteristics of the multi-layer composite material of firefighting gloves and the protection requirements, with the aim of improving the strength of the sewing of firefighting gloves.

[0003] In related technologies, the tension control method for fire gloves is usually achieved by manually adjusting the tension knob setting of the sewing device according to the sewing location and the type of composite material. Then, during the sewing process, the real-time status of the sewing thread is observed by the naked eye, and the tension knob setting is manually adjusted according to the real-time status of the sewing thread to finally achieve the sewing of the fire gloves.

[0004] Regarding the aforementioned technologies, the tension knob setting of the sewing device is manually adjusted according to the sewing part of the fire glove and the type of composite material. However, when the sewing part is a waterproof layer, the needle hole needs to be sealed after sewing. If the tension knob setting is not adjusted properly, the waterproof strip at the needle hole of the waterproof layer cannot be completely adhered, resulting in a decrease in the firmness of the fire glove sewing. There is still room for improvement. Summary of the Invention

[0010] Optionally, the steps of analyzing the adjusted wire feed and current needle insertion resistance to determine the final wire feed include: Obtain the historical needle insertion resistance at preset sampling points; Calculate the difference between the current needle insertion resistance and the historical needle insertion resistance to generate the needle insertion resistance deviation; Calculate the quotient of the needle insertion resistance deviation and the preset sampling time difference to generate the needle insertion resistance change rate; The final wire feed rate is determined by analyzing the changes in the wire feed amount and needle insertion resistance.

[0011] Optionally, the steps of analyzing the changes in the feed rate and needle resistance to determine the final feed rate include: Determine whether the rate of change of needle insertion resistance meets the preset range of standard rate of change of resistance; If the conditions are met, the adjusted cable delivery amount will be defined as the final cable delivery amount. If the conditions are not met, the rate of change of needle resistance, the amount of wire fed, and the preset resistance sensitivity coefficient are analyzed to determine the final amount of wire fed.

[0012] Optionally, the steps of analyzing the rate of change of needle resistance, adjusting the wire feed amount, and the preset resistance sensitivity coefficient to determine the final wire feed amount include: Calculate the product of the needle insertion resistance change rate and the resistance sensitivity coefficient to generate the tension adjustment coefficient; The wire feed rate and tension adjustment coefficient are analyzed to determine the final wire feed rate.

[0013] Secondly, this application provides a fire-fighting glove sewing tension control system, which adopts the following technical solution: A fire-fighting glove sewing tension control system, comprising: The acquisition module is used to acquire system trigger signals, suture start signals, suture stage return values, and current needle insertion resistance.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. By controlling the sewing device to sew the fire glove material with a reference thread feed, the return value during the sewing stage and the reference thread feed are analyzed to determine the adjustment thread feed. The final thread feed is determined by analyzing the adjusted thread feed and the current needle insertion resistance. Based on the final thread feed, the sewing device is controlled to continue sewing the fire glove material to produce the finished fire glove. Thus, when sewing the waterproof layer of the fire glove, the real-time adjustment of the thread feed effectively avoids the situation where the waterproof strip is not completely adhered due to tension mismatch, thereby ensuring the effect of improving the strength of the fire glove sewing. 2. A vibration deviation value is generated by calculating the difference between the pressure foot vibration intensity and the standard vibration intensity. When the vibration deviation value is determined to be within the range of the standard vibration deviation, the baseline thread feed amount is directly defined as the adjustment thread feed amount. If it is not, the adjustment thread feed amount is determined after analyzing the vibration deviation value and the current thread feed amount. Thus, when sewing the waterproof layer, the tension of the sewing thread is controlled by adjusting the thread feed amount in real time, which effectively avoids the situation where the waterproof strip is not completely adhered, thereby ensuring the effect of improving the firmness of the fire glove sewing. 3. By calculating the difference between the current needle insertion resistance and the historical needle insertion resistance, the needle insertion resistance deviation is generated. The quotient of the needle insertion resistance deviation and the sampling time difference is then used to generate the needle insertion resistance change rate. Based on the analysis of the adjustment of the suture feed amount and the needle insertion resistance change rate, the final suture feed amount is determined. By using the change rate of resistance at needle insertion, it is determined whether there is a sudden change in thickness during suturing. This allows for the adjustment of the suture feed amount, effectively avoiding suture breakage or suture slippage due to tension mismatch. Attached Figure Description

[0024] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figures 1 to 7 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0025] This application discloses a method for controlling the stitching tension of fire-fighting gloves. Specifically, it discloses a stitching device and a processing terminal. The processing terminal is communicatively connected to the stitching device to achieve data interaction and control. After receiving a system trigger signal, the processing terminal controls the stitching device to stitch the fire-fighting glove material with a reference thread feed. After analyzing the return value of the stitching stage and the reference thread feed, the adjusted thread feed is determined. After analyzing the adjusted thread feed and the current needle insertion resistance, the final thread feed is determined. Based on the final thread feed, the stitching device is controlled to continue stitching the fire-fighting glove material to generate the finished fire-fighting glove. Thus, when stitching the waterproof layer of the fire-fighting glove, by adjusting the thread feed in real time, the situation of incomplete adhesion of the waterproof strip due to tension mismatch is effectively avoided, thereby ensuring the effect of improving the strength of the fire-fighting glove stitching.

[0026] Reference Figure 1 This application discloses a method for controlling the sewing tension of firefighting gloves, including the following steps: Step S100: Obtain the system trigger signal.

[0027] Among them, the system trigger signal refers to the system's trigger signal, which is triggered by the operator to activate the system's start switch, thereby sending the level signal representing the system trigger signal to the processing terminal, thus providing the start-up conditions for the suturing device.

[0028] Step S101: Based on the system trigger signal, control the preset sewing device to sew the preset fire glove material with a preset reference thread feed amount, and obtain the sewing start signal.

[0029] In this process, after receiving the system trigger signal, the processing terminal responds to the system trigger signal by controlling the sewing device to sew the fire glove material with a reference thread feed amount, and obtains the sewing start signal so as to obtain the return value of the sewing stage and the current needle insertion resistance in the subsequent process.

[0030] The sewing device is used to sew together fire-fighting glove materials to produce finished fire-fighting gloves. It consists of a thread feeding mechanism, a presser foot assembly, a needle bar assembly, and a control module. The specific model is determined by the operator based on actual conditions. The thread feeding mechanism delivers the thread according to a set feed rate. It is equipped with a thread feed encoder, which records the length of thread delivered during one sewing stroke. The presser foot assembly secures the fire-fighting glove material. It is equipped with a pressure sensor and a vibration sensor. The pressure sensor detects the resistance when the needle pierces the material, and the vibration sensor detects feedback signals related to thread tension. The needle bar assembly drives the needle to complete the sewing stroke. The control module communicates with the processing terminal to receive sewing commands.

[0031] The reference thread feed amount refers to the thread feed length of the sewing device when the thread tension is matched, which is set in advance by the operator. By determining the reference thread feed amount, the sewing device can be controlled to sew the fire glove material with the reference thread feed amount, so as to facilitate subsequent determination and adjustment of the thread feed amount.

[0032] Firefighting glove materials refer to the raw materials used to sew the finished firefighting gloves. For example, abrasion-resistant and flame-retardant aramid fabric is used to sew the outer layer, polytetrafluoroethylene waterproof and breathable membrane is used to sew the waterproof layer, and aramid insulation cotton is used to sew the heat insulation layer. The specific type is determined by the operator based on the actual situation.

[0033] The sewing start signal is the signal that the sewing device begins sewing. After the sewing device starts sewing the fire glove material, it sends a level signal representing the sewing start signal to the processing terminal, which then provides the basis for obtaining the return value of the sewing stage and the current needle insertion resistance.

[0034] Step S102: Obtain the return value of the suturing stage and the current needle insertion resistance based on the suturing initiation signal.

[0035] In this process, after receiving the sewing start signal, the processing terminal responds to the sewing start signal by obtaining the sewing stage return value and the current needle insertion resistance. The sewing stage return value is used to determine whether the sewing area is a waterproof layer, and the current needle insertion resistance is used to determine the thickness change trend during sewing, thereby ensuring the effect of improving the sewing strength of the fire gloves.

[0036] The stitching stage return value refers to the digital return value corresponding to the stitching stage. For example, if a waterproof layer is being stitched, the stage encoder will return the number 1, which is read by the processing terminal from the stage encoder. By determining the stitching stage return value, it is possible to determine whether the part of the fire glove being stitched is a waterproof layer, thereby improving the strength of the fire glove stitching.

[0037] A stage encoder is a program that returns a digital value corresponding to the section of the fire glove being sewn by the current sewing device. This value is stored by the operator on the processing terminal. By determining the stage encoder, the digital value of the current sewing stage is determined, facilitating subsequent determination of the sewing site inspection results.

[0038] The current needle insertion resistance refers to the resistance encountered when the suture needle penetrates the material of the fire-fighting glove during the current suturing process. It is read by the pressure sensor at the presser foot assembly of the suturing device from the processing terminal. A higher current needle insertion resistance indicates a thicker suture, thus providing data support for determining the final suture feed amount.

[0039] Step S103: Analyze the return value and baseline suture feed amount during the suturing stage to determine the adjustment of the suture feed amount.

[0040] The adjusted thread feed amount refers to the value after adjusting the thread feed amount based on whether the currently sutured area is a waterproof layer. This value is obtained by analyzing the return value from the suture stage and the baseline thread feed amount at the processing terminal. Specific methods are detailed in [reference needed]. Figure 2 The steps are as follows. By adjusting the thread feed amount in real time when sewing the waterproof layer of the fire glove, the situation of incomplete adhesion of the waterproof strip due to tension mismatch can be effectively avoided, thereby ensuring the improved strength of the fire glove sewing.

[0041] Step S104: Analyze the adjusted wire feed amount and the current needle insertion resistance to determine the final wire feed amount.

[0042] The final suture feed amount refers to the value obtained after adjusting the suture feed amount based on the thickness changes during suturing. This value is determined by the processing terminal after analyzing the adjusted suture feed amount and the current needle insertion resistance. For specific methods, please refer to [link to relevant documentation]. Figure 5 The steps are as follows. By determining the final thread feed amount, the thread feed amount can be adjusted in a timely manner when there is a sudden change in thickness, thereby effectively avoiding thread breakage or slippage due to tension mismatch, and thus ensuring the improved strength of the fire gloves.

[0043] Step S105: Control the sewing device to continue sewing the fire glove material according to the final thread feed amount to produce the finished fire glove.

[0044] Among them, the finished fire glove refers to the finished product obtained by sewing fire glove material. The processing terminal controls the sewing device to continue sewing the fire glove material according to the final thread feed amount. In this way, the tension during sewing is further controlled by controlling the thread feed amount, thereby improving the strength of the fire glove sewing.

[0045] Reference Figure 2The analysis of return values ​​and baseline suture feed during the suturing stage, to determine the steps for adjusting the suture feed, includes: Step S200: Determine the detection result of the suture site based on the correspondence between the return value of the suture stage and the preset suture pattern.

[0046] The correspondence between the suturing mode and the suturing mode refers to the correspondence between the return value of the suturing stage and the suturing mode. For example, when the return value of the suturing stage is 1, it means that the part being suturing is a waterproof layer. At this time, the detection result of the corresponding suturing part is the waterproof suturing result. The operator will form a mapping table by matching the return value of the suturing stage with the suturing part one by one.

[0047] The suture site detection result refers to the detection result of the current suture site, including the result of ordinary suture and waterproof suture. This result is obtained by the processing terminal by looking up the corresponding suture mode in a mapping table based on the return value at the suture stage. By identifying and retrieving the suture site detection result, it is determined whether waterproof layer suture is currently being performed, which facilitates subsequent adjustments to the suture feed amount.

[0048] Step S201: Determine whether the suture site detection result is a preset ordinary suture result or a preset waterproof suture result.

[0049] The method involves determining whether the suture site is a standard suture or a waterproof suture by analyzing the inspection results. This helps to identify whether the suture site is waterproof and adjust the amount of thread fed to improve the strength of the fire gloves.

[0050] The results of routine stitching refer to the inspection results of areas other than the waterproof layer, which are stored by the operator at the processing terminal. By determining that the current stitching area is not the waterproof layer, the fire glove material is continued to be stitched with the reference thread feed to ensure the effectiveness of improving the strength of the fire glove stitching.

[0051] The waterproof suturing result refers to the inspection result of the suturing waterproof layer, which is stored by the operator at the processing terminal. By determining the waterproof suturing result, the currently suturing area is identified as a waterproof layer. If the suture feed is not adjusted in time, tension mismatch will occur, leading to incomplete adhesion of the waterproof adhesive strip.

[0052] Step S2011: If the result is a normal suture, the baseline suture feed amount is defined as the adjusted suture feed amount.

[0053] If the test result of the suture site is a normal suture result, it means that the sutured area is not a waterproof layer and there is no situation where the waterproof strip does not adhere due to tension mismatch. Therefore, the processing terminal directly defines the baseline wire feed amount as the adjustment wire feed amount, thereby ensuring the effect of improving the firmness of the fire glove suture.

[0054] Step S2012: If the result is a waterproof stitch, obtain the current thread feed amount and presser foot vibration intensity.

[0055] If the test result of the sewn part is a waterproof sewn result, it means that the current sewn part is a waterproof layer. If the tension is too high, it will cause the needle hole of the sewn part to become larger, resulting in the waterproof strip not being able to completely seal the needle hole. If the tension is too low, it will cause the sewn part to loosen, resulting in wrinkles after the waterproof strip is attached, thus reducing the firmness and waterproof performance of the fire glove. Therefore, the processing terminal obtains the current wire feed amount and the vibration intensity of the presser foot to provide data support for subsequent determination and adjustment of the wire feed amount.

[0056] The current thread feed refers to the length of thread delivered by the sewing device in one sewing stroke, which is read from the thread feed encoder by the processing terminal. A longer current thread feed indicates lower tension, thus providing data support for subsequent determination and adjustment of the thread feed.

[0057] A thread feed encoder is an encoder installed on the thread feeding mechanism of a sewing device to record the length of thread delivered by the sewing device in one sewing stroke. The thread feed encoder determines the amount of thread fed by recording the number of revolutions of the thread feeding mechanism. The specific model is determined by the operator based on the actual situation.

[0058] Presser foot vibration intensity refers to the feedback signal of vibration intensity related to thread tension, which is read by the processing terminal from the vibration sensor installed at the presser foot assembly. When the presser foot vibration intensity is greater, it indicates that the thread tension is greater. If the thread feed is not adjusted at this time, the needle hole will become larger due to tension, resulting in incomplete adhesion of the waterproof tape.

[0059] Step S20121: Analyze the baseline wire feed amount, the current wire feed amount, and the pressure foot vibration intensity to determine the wire feed amount to be adjusted.

[0060] After determining the current wire feed amount and the pressure foot vibration intensity, the processing terminal analyzes the baseline wire feed amount, the current wire feed amount, and the pressure foot vibration intensity to determine the adjusted wire feed amount. The specific method is described in [reference needed]. Figure 3 The steps are as follows. By adjusting the thread feed amount in real time when sewing the waterproof layer of the fire glove, the situation of incomplete adhesion of the waterproof strip due to tension mismatch can be effectively avoided, thereby ensuring the improved strength of the fire glove sewing.

[0061] The adjustment of the wire feed amount in this step is the same as the adjustment of the wire feed amount in step S2011. The difference is that the adjustment of the wire feed amount in this step is obtained by the processing terminal after analyzing the reference wire feed amount, the current wire feed amount and the vibration intensity of the pressure foot.

[0062] Reference Figure 3The steps for adjusting the wire feed amount include analyzing the baseline wire feed amount, the current wire feed amount, and the pressure foot vibration intensity. Step S300: Calculate the difference between the pressure foot vibration intensity and the preset standard vibration intensity to generate a vibration deviation value.

[0063] The vibration deviation value refers to the deviation between the vibration intensity of the current presser foot and the vibration intensity when matched with the suture tension. It is obtained by the processing terminal calculating the difference between the presser foot vibration intensity and the standard vibration intensity. By determining the vibration deviation value, the deviation between the current tension and the suture tension can be reflected, which facilitates the subsequent determination and adjustment of the thread feed amount.

[0064] Standard vibration intensity refers to the vibration intensity at which the tension of the suture is fed back to the presser foot assembly when the suture tension is matched. It is set in advance by the operator. By determining the standard vibration intensity, a criterion is provided for determining the direction of tension change, thereby providing data support for determining the vibration deviation value.

[0065] Step S301: Determine whether the vibration deviation value meets the preset standard vibration deviation range.

[0066] The standard vibration deviation refers to the vibration deviation value of the presser foot when measuring the tension matching of the suture during sewing. The range of the standard vibration deviation is a range that is set in advance by the operator. By judging whether the vibration deviation value is within the range of the standard vibration deviation, it is determined whether the tension of the current suture meets the requirements of the sewing site, so as to determine and adjust the suture feed amount in the future.

[0067] Step S3011: If the condition is met, the baseline feed amount is defined as the adjusted feed amount.

[0068] If the vibration deviation value is within the range of the standard vibration deviation, it means that the tension of the current suture meets the requirements of the sewage position. At this time, the processing terminal directly defines the reference suture amount as the adjustment suture amount, thereby ensuring the effect of improving the firmness of the fire glove sewage.

[0069] Step S3012: If it does not meet the requirements, analyze the vibration deviation value and the current wire feeding amount to determine the adjustment of the wire feeding amount.

[0070] If the vibration deviation value is outside the standard vibration deviation range, it indicates that the current suture tension does not meet the requirements of the suture site. Excessive tension will enlarge the needle holes, preventing the waterproof tape from fully adhering to them. Insufficient tension will cause the suture to loosen, resulting in wrinkles after the waterproof tape adheres, thus reducing the waterproof performance of the fire gloves. Therefore, the processing terminal analyzes the vibration deviation value and the current suture feed rate to determine and adjust the suture feed rate. Specific methods are detailed below. Figure 4 The steps.

[0071] The adjustment of the wire feed amount in this step is the same as the adjustment of the wire feed amount in step S3011. The difference is that the adjustment of the wire feed amount in this step is obtained by the processing terminal after analyzing the vibration deviation value and the current wire feed amount.

[0072] Reference Figure 4 The steps to adjust the wire feed rate by analyzing the vibration deviation value and the current wire feed amount include: Step S400: Calculate the product of the vibration deviation value and the preset wire feed adjustment factor to generate a correction adjustment coefficient.

[0073] The correction adjustment factor measures the proportion by which the thread feed should be increased or decreased based on the original thread feed amount. It is obtained by calculating the product of the vibration deviation value and the thread feed adjustment factor at the processing terminal. By determining the correction adjustment factor, the proportion by which the thread feed amount needs to be increased or decreased can be determined. When the vibration deviation value is positive, it indicates that the thread tension is too high; in this case, the thread feed amount should be increased to reduce the tension. When the vibration deviation value is negative, it indicates that the thread tension is too low; in this case, the thread feed amount should be decreased to increase the tension, thereby ensuring the improved strength of the fire-fighting glove stitching.

[0074] The thread feed adjustment factor is a value that measures the sensitivity of tension to vibration deviation and is set in advance by the operator. By determining the thread feed adjustment factor, the tension of the thread can be adjusted, thereby improving the strength of the fire gloves' stitching.

[0075] Step S401: Calculate the sum of the correction adjustment coefficient and the preset standard adjustment coefficient to generate the feed line adjustment coefficient.

[0076] The thread feed adjustment coefficient measures the total adjustment based on the original thread feed amount. It is calculated by the processing terminal as the sum of the correction adjustment coefficient and the standard adjustment coefficient. When the correction adjustment coefficient is negative, the thread feed adjustment coefficient is less than 1, indicating low tension. Therefore, the current thread feed amount should be reduced. When the correction adjustment coefficient is positive, the thread feed adjustment coefficient is greater than 1, indicating high tension. Therefore, the current thread feed amount should be increased to ensure improved stitch strength in the fire-fighting gloves.

[0077] The standard adjustment factor refers to the adjustment ratio of the current wire feed when the tension is appropriate. In this step, the standard adjustment factor is set to 1, which is predetermined by the operator. By determining the standard adjustment factor, a benchmark is provided for the adjustment ratio of the current wire feed, thereby providing data support for determining the wire feed adjustment factor.

[0078] Step S402: Calculate the product of the wire feeding adjustment coefficient and the current wire feeding amount to generate the adjusted wire feeding amount.

[0079] After determining the thread feed adjustment coefficient, the processing terminal calculates the adjusted thread feed amount by multiplying the adjustment coefficient by the current thread feed amount. When the thread feed adjustment coefficient is less than 1, it indicates that the thread tension is too low. The current thread feed amount should be reduced to increase the tension, thus effectively preventing wrinkles in the waterproof sealing strip due to insufficient tension. When the thread feed adjustment coefficient is greater than 1, it indicates that the thread tension is too high. The current thread feed amount should be increased to reduce the tension, thus effectively preventing the waterproof sealing strip from failing to completely seal the needle hole due to excessive tension, thereby ensuring improved stitching strength of the fire-fighting glove.

[0080] Reference Figure 5 The steps to determine the final wire feed amount by analyzing the adjusted wire feed rate and the current needle insertion resistance include: Step S500: Obtain the historical needle insertion resistance at the preset sampling point.

[0081] The historical needle insertion resistance refers to the resistance encountered when the suture needle pierces the material of the fire-fighting glove during the suturing process at the sampling point. This resistance is read by the pressure sensor at the presser foot assembly of the suturing device from the processing terminal. By determining the historical needle insertion resistance, it is possible to determine whether there is a sudden change in the suture thickness between the current time and the sampling point, providing data support for subsequently determining the deviation of the needle insertion resistance.

[0082] A sampling point refers to the moment when historical needle insertion resistance is sampled, which is predetermined by the operator. By determining the sampling point, the historical needle insertion resistance at that sampling moment can be determined, facilitating the subsequent determination of needle insertion resistance deviation.

[0083] Step S501: Calculate the difference between the current needle insertion resistance and the historical needle insertion resistance to generate the needle insertion resistance deviation.

[0084] The needle insertion resistance deviation refers to the difference in resistance between the current moment and the sampling point moment when the needle pierces the sewing material of the fire glove. It is obtained by the processing terminal by calculating the difference between the current needle insertion resistance and the historical needle insertion resistance. The larger the needle insertion resistance deviation, the greater the change in resistance to the needle piercing the sewing material of the fire glove, and thus the greater the change in thickness during sewing, thereby providing data support for subsequent determination of the needle insertion resistance change rate.

[0085] Step S502: Calculate the quotient of the needle insertion resistance deviation and the preset sampling time difference to generate the needle insertion resistance change rate.

[0086] The needle insertion resistance change rate measures the rate at which the thickness of the fire glove material changes during suturing. It is calculated by the processing terminal as the quotient of the needle insertion resistance deviation and the sampling time difference. A positive needle insertion resistance change rate indicates that the current suturing thickness is greater than the thickness at the sampling point; if the tension is not reduced, the suture will break due to excessive tension. A negative needle insertion resistance change rate indicates that the current suturing thickness is less than the thickness at the sampling point; if the tension is not increased, the suture will fail due to insufficient tension.

[0087] The sampling time difference refers to the time difference for detecting resistance during needle insertion, which is preset by the operator. By determining the sampling time difference, the thickness change during suturing within the sampling time difference can be determined, so as to facilitate the subsequent determination of the final suture feed amount.

[0088] Step S503: Analyze the changes in the wire feed amount and needle insertion resistance to determine the final wire feed amount.

[0089] After determining the rate of change of needle insertion resistance, the processing terminal analyzes the adjusted wire feed amount and the rate of change of needle insertion resistance to determine the final wire feed amount. The specific method is described in [reference needed]. Figure 6 The steps are as follows. By determining the final thread feed amount, the thread feed amount can be adjusted in a timely manner when there is a sudden change in thickness, thereby effectively avoiding thread breakage or slippage due to tension mismatch, and thus ensuring the improved strength of the fire gloves.

[0090] Reference Figure 6 The steps to determine the final wire feed amount by analyzing the changes in the wire feed rate and needle insertion resistance include: Step S600: Determine whether the rate of change of needle insertion resistance meets the preset range of standard resistance change rate.

[0091] The standard resistance change rate measures the rate of change in the thickness of the fire glove material during tension matching. The range of the standard resistance change rate is a pre-set value determined by the operator. By judging whether the needle insertion resistance change rate is within the range of the standard resistance change rate, it is determined whether the suture feed amount needs adjustment, thus facilitating the subsequent determination of the final suture feed amount.

[0092] Step S6001: If the condition is met, the adjusted wire feed amount is defined as the final wire feed amount.

[0093] If the rate of change of needle insertion resistance is within the range of the standard rate of change of resistance, it indicates that the current suturing state is not in a state of sudden change in thickness. Therefore, the processing terminal directly defines the adjusted thread feed amount as the final thread feed amount to ensure the effect of improving the firmness of the fire glove suturing.

[0094] Step S6002: If it does not meet the requirements, analyze the needle resistance change rate, the adjusted wire feed amount, and the preset resistance sensitivity coefficient to determine the final wire feed amount.

[0095] If the change in needle insertion resistance is outside the range of the standard resistance change rate, it indicates that the suture is currently in a state of sudden thickness change. In this case, the processing terminal analyzes the change rate of needle insertion resistance, adjusts the suture feed amount, and the resistance sensitivity coefficient to determine the final suture feed amount. The specific method is described in [reference needed]. Figure 7 The steps involve determining the final thread feed amount, which allows for timely adjustments to the thread feed amount when there are sudden changes in thickness, thereby ensuring improved strength of the fire gloves' seams.

[0096] The resistance sensitivity coefficient is a value that measures how sensitive resistance is to the tension of the suture, and it is preset by the operator. By determining the resistance sensitivity coefficient, the proportion of suture feed that needs to be adjusted can be determined based on the rate of change in needle insertion resistance, thereby improving the strength of the fire-fighting glove stitching.

[0097] The final wire feed amount in this step is the same as the final wire feed amount in step S6001. The difference is that the final wire feed amount in this step is obtained by the processing terminal after analyzing the change rate of needle resistance, adjusting the wire feed amount and resistance sensitivity coefficient.

[0098] Reference Figure 7 The steps to determine the final wire feed amount by analyzing the rate of change of needle resistance, adjusting the wire feed amount, and the preset resistance sensitivity coefficient include: Step S700: Calculate the product of the needle resistance change rate and the resistance sensitivity coefficient to generate the tension adjustment coefficient.

[0099] The tension adjustment coefficient is a proportional value used to adjust the suture feed rate based on the rate of change in needle insertion resistance. It is calculated by the processing terminal as the product of the rate of change in needle insertion resistance and the resistance sensitivity coefficient. When the rate of change in needle insertion resistance is positive, the tension adjustment coefficient is also positive, thus increasing the suture feed rate to reduce tension. When the rate of change in needle insertion resistance is negative, the tension adjustment coefficient is also negative, thus decreasing the suture feed rate to increase tension.

[0100] Step S701: Analyze the adjustment of wire feed amount and tension adjustment coefficient to determine the final wire feed amount.

[0101] After determining the tension adjustment coefficient, the processing terminal analyzes the adjusted wire feed amount and the tension adjustment coefficient to determine the final wire feed amount, which can be expressed as follows: ,in For the final wire delivery quantity, To adjust the wire feed rate, This refers to the tension adjustment coefficient. When the thickness of the suture increases, the tension adjustment coefficient is positive. Therefore, increasing the thread feed reduces tension, effectively preventing the suture from breaking due to excessive tension. When the thickness of the suture decreases, the tension adjustment coefficient is negative. Therefore, decreasing the thread feed increases tension, effectively preventing thread slippage due to insufficient tension, thus ensuring the improved strength of the fire-fighting glove seam.
