Description

Technical Field

[0001] This invention relates to the textile field, and more specifically to weaving machine systems and fabric quality control methods. Background Technology

[0002] Currently, traditional looms mainly consist of five mechanisms: warp feed assembly, warp winding assembly, shedding mechanism, weft insertion mechanism, and beat-up mechanism. These mechanisms are all connected to the main shaft, which provides the power source, and they operate in a certain sequence within a specific angle range of the main shaft.

[0003] However, the operation of these mechanisms is strongly coupled nonlinearly with the main shaft. Due to inherent mechanical limitations, such as the three main types of weft-beating mechanisms in traditional looms, namely four-bar weft-beating mechanisms, six-bar weft-beating mechanisms, and conjugate cam weft-beating mechanisms, the main power source of the four-bar weft-beating mechanism can only come from the main shaft. The continuous rotation of the main shaft is converted into the reciprocating periodic oscillation of the weft-beating mechanism through a crankshaft four-bar mechanism. The basic principles of the six-bar weft-beating mechanism and the conjugate cam weft-beating mechanism are similar to those of the four-bar weft-beating mechanism. They all need to convert the periodic motion of the main shaft into the periodic reciprocating motion of the reed through mechanical transmission mechanisms such as crankshaft six-bar mechanisms or conjugate cam mechanisms. They only adjust the fabric defects by controlling the main shaft, making it difficult to effectively control the fabric defects. Summary of the Invention

[0004] The main objective of this invention is to provide a loom system and a fabric quality control method, which aims to solve the problem that traditional looms cannot effectively control fabric defects by relying solely on spindle control.

[0005] To achieve the above objectives, the present invention proposes a weaving machine system, the weaving machine system comprising:

[0006] The warp feed mechanism is used to feed the warp yarns to the weaving position;

[0007] An opening mechanism is provided at the weaving position and is used to layer the warp yarns to form a shed and a weave.

[0008] The weft insertion mechanism is used to guide the weft yarn through the shed;

[0009] The beat-up mechanism is used to push the weft yarn toward the weft end to form a fabric, and the warp feed crimping mechanism is also used to crimp the fabric.

[0010] A control device is used to control an actuator to perform corresponding actions to improve the actual weft density based on the difference between the actual weft density and the theoretical weft density of the fabric. The actuator is a direct-drive mechanism and is at least one of the warp feeding and crimping mechanism, the shedding mechanism, the weft insertion mechanism, and the beat-up mechanism.

[0011] Preferably, the beat-up mechanism includes a beat-up drive and a beat-up piece, the beat-up drive being used to drive the beat-up piece to push the weft yarn toward the weft opening to form a fabric, and the control device being used to control the beat-up drive to adjust the beat-up stroke and / or beat-up force of the beat-up piece to push the weft yarn toward the weft opening according to the difference.

[0012] Preferably, the shedding mechanism includes a shedding drive and a shedding assembly. The shedding assembly includes two heald frames that are movably connected to each other. The shedding drive is used to drive the two heald frames away from each other and to layer the warp yarns to form the shed and the weave. The control device is communicatively connected to the shedding drive and is used to control the shedding drive to adjust the shedding parameters of the shedding assembly according to the difference. The shedding parameters include the shedding stroke, shedding speed, and shedding acceleration between the two heald frames.

[0013] Preferably, the warp feeding and winding mechanism includes a warp feeding assembly and a winding assembly. The warp feeding assembly includes a warp feeding drive and a warp beam connected to the warp feeding drive. The warp beam is used for winding the warp yarns. The warp feeding drive is used to drive the warp beam to rotate and release the warp yarns, and cooperates with the winding assembly to feed the warp yarns to the weaving position. The control device is communicatively connected to the warp feeding drive. The control device is used to control the warp feeding drive to adjust the release rate and / or release amount of the warp yarns released by the warp beam according to the difference.

[0014] Preferably, the crimping assembly includes a crimping drive and a spool connected to the crimping drive. The crimping drive is used to cooperate with the warp feed drive to feed the warp yarn to the weaving position and to drive the spool to rotate and crimp the fabric. The control device is communicatively connected to the crimping drive and is also used to control the crimping drive to adjust the crimping rate and / or crimping amount of the spool when crimping the fabric according to the difference.

[0015] Preferably, the weft insertion mechanism includes a weft insertion drive for guiding the weft yarn through the shed, the control device is communicatively connected to the weft insertion drive, and the control device is further used to control the weft insertion drive to adjust the guiding speed and / or guiding amount of guiding the weft yarn through the shed.

[0016] Furthermore, the present invention also provides a fabric quality control method, applying the loom system described above, the fabric quality control method comprising the following steps:

[0017] Obtain the actual latitude density distance and the theoretical latitude density distance based on the latitude density setting value;

[0018] Compare the actual latitude density distance with the theoretical latitude density distance and calculate the difference;

[0019] The actuator is controlled to perform corresponding actions based on the difference to improve the actual latitude-density distance.

[0020] Preferably, the step of controlling the actuator to perform corresponding actions based on the difference to improve the actual latitude density distance includes:

[0021] If the actual weft density distance is greater than the theoretical weft density distance, then the weft-beating drive is controlled according to the difference to increase the weft-beating stroke and / or weft-beating force of the weft-beating component to push the weft yarn toward the weft opening;

[0022] If the actual weft density distance is less than the theoretical weft density distance, then the weft-beating drive is controlled according to the difference to reduce the weft-beating stroke and / or weft-beating force of the weft-beating component pushing the weft yarn towards the weft opening.

[0023] Preferably, the step of controlling the actuator to perform corresponding actions based on the difference to improve the actual latitude density distance includes:

[0024] If the actual weft density distance is greater than the theoretical weft density distance, the opening drive component is controlled to increase the opening stroke of the opening assembly based on the difference.

[0025] If the actual weft density distance is less than the theoretical weft density distance, the opening drive component is controlled to reduce the opening stroke of the opening assembly based on the difference.

[0026] Preferably, the step of controlling the actuator to perform corresponding actions based on the difference to improve the actual latitude density distance includes:

[0027] If the actual weft density distance is greater than the theoretical weft density distance, the warp drive is controlled according to the difference to reduce the release rate and / or release amount of the warp yarns released from the warp beam;

[0028] If the actual weft density distance is less than the theoretical weft density distance, the warp feed drive is controlled according to the difference to increase the release rate and / or release amount of the warp yarn released by the warp beam.

[0029] Preferably, the step of controlling the actuator to perform corresponding actions based on the difference to improve the actual latitude density distance includes:

[0030] If the actual weft density distance is greater than the theoretical weft density distance, the curling drive is controlled according to the difference to reduce the curling rate and / or curling amount of the fabric curled on the roller.

[0031] If the actual weft density is less than the theoretical weft density, the curling drive is controlled according to the difference to increase the curling rate and / or curling amount of the fabric on the roller.

[0032] Preferably, the step of controlling the actuator to perform corresponding actions based on the difference to improve the actual latitude density distance includes:

[0033] Control the weft insertion drive to adjust the guiding speed and / or guiding amount of the weft yarn through the shed.

[0034] In addition, the present invention provides a computer-readable storage medium storing a fabric quality control program, which, when executed by a processor, implements the steps of the fabric quality control method as described above.

[0035] In the technical solution of the present invention, the loom system includes a warp feed and winding mechanism, a shedding mechanism, a weft insertion mechanism, a weft beat-up mechanism, and a control device. The warp feed and winding mechanism feeds the warp yarns to the weaving position. The shedding mechanism, located at the weaving position, layers the warp yarns to form a shed and a weft opening. The weft insertion mechanism passes the weft yarns through the shed. The weft beat-up mechanism pushes the weft yarns toward the weft opening to form a fabric. The warp feed and winding mechanism winds up the fabric. Throughout the weaving process, the control device controls the actuator to perform corresponding actions based on the difference between the actual weft density and the theoretical weft density to improve the actual weft density. The actuator is at least one of the warp feed and winding mechanism, the shedding mechanism, the weft insertion mechanism, and the weft beat-up mechanism. It can be at least one of them, or a combination of any two, any three, or all of them. The loom system of the present invention controls the direct-drive actuator, thereby making the actuator and the main shaft independent of each other, eliminating the traditional weft insertion conversion mechanism that is strongly coupled to the main shaft. This makes the actuator and the main shaft independent of each other, and the control device controls the actuator to perform corresponding actions to improve the actual weft density distance, so as to complete the quality control of fabric defects.

[0046] Please refer to the appendix. Figure 1 As shown, the present invention proposes a loom system including a warp feed and crimping mechanism 1, a shedding mechanism 2, a weft insertion mechanism 3, a beat-up mechanism 4, and a control device. The warp feed and crimping mechanism 1 is used to feed the warp yarns 20 to the weaving position 10. The shedding mechanism 2 is located at the weaving position 10 and is used to layer the warp yarns 20 to form a shed 30 and a weft opening 40. The weft insertion mechanism 3 is used to guide the weft yarns through the shed 30. The beat-up mechanism 4 pushes the weft yarns toward the weft opening 40 to form a fabric 50. The warp feed and crimping mechanism 1 is also used to crimp the fabric 50. The control device is communicatively connected to the beat-up drive 41. The control device is used to control the actuator to perform corresponding actions to improve the actual weft density based on the difference between the actual weft density and the theoretical weft density of the fabric 50. The actuator is a direct-drive mechanism and is at least one of the warp feed and crimping mechanism 1, the shedding mechanism 2, the weft insertion mechanism 3, and the beat-up mechanism 4.

[0047] The loom system of the present invention is applicable to air-jet looms, water-jet looms, and rapier looms. The loom system includes a warp feed and winding mechanism 1, a shedding mechanism 2, a weft insertion mechanism 3, a beat-up mechanism 4, and a control device. The warp feed and winding mechanism 1 feeds the warp yarns 20 to the weaving position 10. The shedding mechanism 2, located at the weaving position 10, layers the warp yarns 20 to form a shed 30 and a weft opening 40. The weft insertion mechanism 3 passes the weft yarns through the shed 30. The beat-up mechanism 4 includes pushing the weft yarns introduced into the shed 30 by the weft insertion mechanism 3 towards the weft opening 40 to form a fabric 50. The warp feed and winding mechanism 1 winds up the fabric 50. Throughout the weaving process, the control device controls the actuators to perform corresponding actions based on the difference between the actual weft density and the theoretical weft density to improve the actual weft density. The actuators are at least one of the warp feed and winding mechanism, the shedding mechanism, the weft insertion mechanism, and the beat-up mechanism; they can be at least one of these, or a combination of any two, any three, or all of them. In the loom system of the present invention, the actuator is a direct-drive actuator that is independent of the main shaft, eliminating the need for the traditional weft insertion conversion mechanism that is strongly coupled to the main shaft. The actuator is controlled by a control device to perform corresponding actions to improve the actual weft density distance, thereby completing the quality control of 50 defects in the fabric.

[0048] In one embodiment, the beat-up mechanism 4 includes a beat-up drive 41 and a beat-up piece 42. The beat-up drive 41 drives the beat-up piece 42 to push the weft yarn towards the weft opening 40 to form the fabric 50. A control device is communicatively connected to the beat-up drive 41 and is used to control the beat-up drive 41 to adjust the beat-up stroke and / or beat-up force of the beat-up piece 42 to push the weft yarn towards the weft opening 40 based on the difference. Throughout the weaving process, the control device is communicatively connected to the beat-up drive 41. The control device controls the beat-up drive 41 to adjust the beat-up stroke and / or beat-up force of the beat-up piece 42 to push the weft yarn towards the weft opening 40 based on the difference between the actual weft density and the theoretical weft density. If the actual weft density is greater than the theoretical weft density, the beat-up stroke and / or beat-up force are increased, thereby reducing the actual weft density; if the actual weft density is less than the theoretical weft density, the beat-up stroke and / or beat-up force are decreased, thereby increasing the actual weft density and making the actual weft density approach the theoretical weft density. The weft-beating mechanism 4 can use a linear drive unit to directly drive the weft-beating reed to achieve horizontal weft-beating motion. The weft-beating drive component 41 is a linear drive unit, and the weft-beating component 42 is the weft-beating reed. The linear drive unit can be a linear motor, or other mechanisms that can achieve equivalent linear horizontal weft-beating motion, such as a cylinder, electric cylinder, or ball screw. The control device can adjust parameters such as weft-beating stroke, weft-beating force, weft-beating speed, and weft-beating acceleration, and control the weft-beating drive component 41 to perform weft-beating according to these parameters.

[0049] The shedding mechanism 2 includes a shedding drive and a shedding assembly. The shedding assembly includes two heald frames 21 that are movably connected to each other. The shedding drive drives the two heald frames 21 to move away from each other and to separate the warp yarns 20 into layers to form the shed 30 and the weave 40. A control device is communicatively connected to the shedding drive and is also used to control the shedding drive to adjust the shedding parameters of the shedding assembly based on the difference. The shedding parameters include the shedding stroke, shedding speed, and shedding acceleration between the two heald frames 21. This eliminates the need for traditional top-mounted, bottom-mounted, or main shaft crank-type shedding mechanisms 2. The shedding drive directly drives the two heald frames 21 to achieve vertical movement. The shedding drive is a linear drive unit, which can be a linear motor, a cylinder, an electric cylinder, a ball screw, or other mechanisms that can achieve equivalent linear motion. The control device can adjust the shedding stroke according to the difference. If the actual weft density distance is greater than the theoretical weft density distance, the shedding stroke is increased; if the actual weft density distance is less than the theoretical weft density distance, the shedding stroke is decreased. The control device controls the shedding drive to drive the heald frame 21 to move up and down according to the shedding stroke and / or shedding trajectory. The heald frame 21 moves up and down in layers, so that the warp yarn 20 passing through the center eye of the heald frame 21 can move in layers to form the shed 30 and the weaving edge 40, so as to ensure that the weft insertion mechanism 3 can smoothly pass the ejected weft yarn through the shed 30.

[0050] In one embodiment, the warp feeding and curling mechanism 1 includes a warp feeding component 11 and a curling component 12. The warp feeding component 11 is used to feed the warp yarn 20 to the weaving position 10, and the curling component 12 is used to curl the fabric 50. After the warp feeding component 11 feeds the warp yarn 20 to the weaving position 10 and weaves the fabric 50, the curling component 12 curls the fabric 50.

[0051] Specifically, in one embodiment, the warp feed assembly 11 includes a warp feed drive and a warp beam connected to the warp feed drive. The warp beam is used for winding the warp yarn 20. The warp feed drive is used to drive the warp beam to rotate and release the warp yarn, and cooperates with the crimping assembly 12 to feed the warp yarn 20 to the weaving position 10. The control device is communicatively connected to the warp feed drive and is also used to control the warp feed drive to adjust the release rate and / or release amount of the warp yarn 20 released by the warp beam according to the difference. The warp feed assembly 11 uses a warp feed drive, which can be a motor, making the warp feed assembly 11 a direct-drive electronic warp feed assembly 11. This eliminates the need for a multi-stage gear transmission mechanism coupled between the warp feed assembly 11 and the main shaft, and the warp beam is directly driven by an independent warp feed drive to release the warp yarn. The control device can adjust the release rate and release amount according to the difference. If the actual weft density distance is greater than the theoretical weft density distance, the release rate and / or release amount will be reduced; if the actual weft density distance is less than the theoretical weft density distance, the release rate and / or release amount will be increased. The control device controls the warp feeding drive to feed the warp according to the release rate and release amount.

[0052] In another embodiment, the crimping assembly 12 includes a crimping drive and a spool connected to the crimping drive. The crimping drive cooperates with the warp feed drive to feed the warp yarn 20 to the weaving position and drives the spool to rotate and crimp the fabric 50. A control device is communicatively connected to the crimping drive and is also used to adjust the crimping rate and / or crimping amount according to the difference. The crimping assembly 12 uses a crimping drive, which can be a motor, making the crimping assembly 12 a direct-drive electronic crimping assembly 12. This eliminates the need for a multi-stage gear transmission mechanism coupled to the main shaft, allowing the independent crimping drive to directly drive the spool to rotate and crimp the fabric 50. The control device can adjust the crimping rate and crimping amount according to the difference. If the actual weft density is greater than the theoretical weft density, the crimping rate and / or crimping amount are reduced; if the actual weft density is less than the theoretical weft density, the crimping rate and / or crimping amount are increased. The control device controls the crimping drive to crimp the fabric 50 according to the crimping rate and crimping amount.

[0053] Furthermore, the weft insertion mechanism 3 includes a weft insertion drive for passing the weft yarn through the shed 30. A control device is communicatively connected to the weft insertion drive, and the control device is also used to control the weft insertion drive to adjust the guiding speed and / or guiding amount of the weft yarn passing through the shed 30. In one embodiment, taking the weft insertion mechanism 3 of a water-jet loom as an example, the weft insertion mechanism 3 includes a weft insertion drive, making the weft insertion mechanism 3 a direct-drive water-jet weft insertion mechanism 3, eliminating intermediate multi-stage mechanical transmission links and decoupling the water-jet motion from the main shaft motion. A direct-drive linear drive unit directly drives the water pump plunger to achieve periodic water suction and spraying functions. The direct-drive linear drive unit can be a linear motor, or an actuator with equivalent linear drive effect such as a cylinder, electric cylinder, or ball screw. Related parameters, such as the water-jet plunger stroke, water volume, and water pressure, can be freely adjusted to adapt to different process requirements, either manually or by program control.

[0054] It should be noted that the warp feeding assembly 11, the crimping assembly 12, the shedding mechanism 2, the weft insertion mechanism 3, and the beat-up mechanism 4 can all adopt direct-drive linear drive units. The advantage is that they can be decoupled from the main shaft and achieve free and independent linear adjustment and control, which is beneficial for the electronic configuration of the process and the improvement and control of fabric quality.

[0055] Furthermore, the present invention also provides a fabric quality control method, using the loom system described above, please refer to the appendix. Figure 2 As shown, the fabric quality control method includes the following steps:

[0056] S1. Obtain the actual latitude density distance and the theoretical latitude density distance based on the latitude density setting value;

[0057] S2. Compare the actual latitude density distance with the theoretical latitude density distance and calculate the difference;

[0058] S3. Based on the difference, the control actuator performs corresponding actions to improve the actual latitude-density distance.

[0059] In this embodiment, the theoretical weft density distance is obtained based on the weft density setting value. The actual weft density distance is compared with the theoretical weft density distance, and the difference is calculated. Based on this difference, the actuator is controlled to perform corresponding actions. For example, the weft-beating stroke and weft-beating force are adjusted according to the difference, and the weft-beating drive is controlled to push the weft yarn in the shed towards the weft opening. The theoretical weft opening position is also obtained based on the machine tension setting value and the weft density setting value. The theoretical opening trajectory is obtained based on the pattern setting value. The opening trajectory includes the maximum opening stroke, opening displacement, opening speed, and opening acceleration, thereby making the actual weft density distance approximate the theoretical weft density distance. The fabric quality control method of this invention can flexibly decouple and control variables that cause fabric quality-related characteristic parameters, broaden the adaptability of different fabric types, improve fabric quality, and enable adaptive and intelligent regulation of fabric quality, avoiding cumbersome mechanical machine adjustments and greatly improving the convenience and efficiency of production.

[0060] More specifically, the steps of S3 include:

[0061] If the actual weft density distance is greater than the theoretical weft density distance, then the weft-beating drive is controlled according to the difference to increase the weft-beating stroke and / or weft-beating force of the weft-beating component to push the weft yarn toward the weft opening;

[0062] If the actual weft density distance is less than the theoretical weft density distance, then the weft-beating drive is controlled according to the difference to reduce the weft-beating stroke and / or weft-beating force of the weft-beating component pushing the weft yarn towards the weft opening.

[0063] In this embodiment, if the actual weft density is greater than the theoretical weft density, it indicates a risk of fabric sparseness defects in this cycle. Increasing the weft stroke and / or weft force can adjust the actual weft density, thereby improving fabric quality. If the actual weft density is less than the theoretical weft density, it indicates a risk of fabric tightness defects in this cycle. Reducing the weft stroke and / or weft force can adjust the actual weft density, thereby improving fabric quality.

[0064] More specifically, the steps of S3 include:

[0065] If the actual weft density distance is greater than the theoretical weft density distance, the opening drive component is controlled to increase the opening stroke of the opening assembly based on the difference.

[0066] If the actual weft density distance is less than the theoretical weft density distance, the opening drive component is controlled to reduce the opening stroke of the opening assembly based on the difference.

[0067] In this embodiment, if the actual weft density distance is greater than the theoretical weft density distance, it indicates a risk of fabric sparseness defects in this cycle. Increasing the shedding stroke can adjust the actual weft density distance, thereby improving fabric quality. If the actual weft density distance is less than the theoretical weft density distance, it indicates a risk of fabric tightness defects in this cycle. Reducing the shedding stroke can adjust the actual weft density distance, thereby improving fabric quality.

[0068] Furthermore, the steps in S3 include:

[0069] If the actual weft density distance is greater than the theoretical weft density distance, the warp drive is controlled according to the difference to reduce the release rate and / or release amount of the warp yarns released from the warp beam;

[0070] If the actual weft density distance is less than the theoretical weft density distance, the warp feed drive is controlled according to the difference to increase the release rate and / or release amount of the warp yarn released by the warp beam.

[0071] In this embodiment, if the actual weft density is greater than the theoretical weft density, it indicates a risk of fabric sparseness defects in this cycle. Reducing the release rate and / or release amount can adjust the actual weft density, thereby improving fabric quality. If the actual weft density is less than the theoretical weft density, it indicates a risk of fabric tightness defects in this cycle. Increasing the release rate and / or release amount can adjust the actual weft density, thereby improving fabric quality.

[0072] In another embodiment, step S3 includes:

[0073] If the actual weft density distance is greater than the theoretical weft density distance, the curling drive is controlled according to the difference to reduce the curling rate and / or curling amount of the fabric curled on the roller.

[0074] If the actual weft density is less than the theoretical weft density, the curling drive is controlled according to the difference to increase the curling rate and / or curling amount of the fabric on the roller.

[0075] In this embodiment, if the actual weft density is greater than the theoretical weft density, it indicates a risk of fabric sparseness defects in this cycle. Reducing the crimp rate and / or crimp amount can adjust the actual weft density, thereby improving fabric quality. If the actual weft density is less than the theoretical weft density, it indicates a risk of fabric tightness defects in this cycle. Increasing the crimp rate and / or crimp amount can adjust the actual weft density, thereby improving fabric quality.

[0076] In another embodiment, step S3 includes:

[0077] Control the weft insertion drive to adjust the guiding speed and / or guiding amount of the weft yarn through the shed.

[0078] The fabric quality control method of the present invention can be implemented using a device comprising the following modules: a crimping control module, a warp feed control module, a weft insertion control module, an shedding control module, and a fabric quality weft density distance judgment module. Specifically, the crimping control module controls the fabric crimping axis, primarily adjusting the crimping rate and crimp amount; the warp feed control module controls the warp beam, primarily adjusting the warp beam release rate and release amount; the weft insertion control module controls the direct-drive weft insertion mechanism, primarily adjusting the weft insertion stroke and weft insertion force; the shedding control module controls the direct-drive shedding mechanism, primarily adjusting the shedding stroke and shedding trajectory; and the fabric quality weft density distance judgment module monitors and judges fabric quality-related characteristic parameters such as weft density distance. It should be noted that the fabric quality weft density distance judgment module can be a specific sensor module or a specific algorithm simulation module.

[0079] The key to fabric quality control lies in the weft density distance judgment module. By judging the fabric quality characteristic parameters such as weft density distance in real time, the deviation between the actual weft density distance and the theoretical weft density distance is compared. If the actual weft density distance deviates from the theoretical weft density distance (too large or too small), it indicates that there is a risk of sparse or dense defects in the fabric during this cycle. In this case, in order to ensure that the fabric quality is normal in subsequent operating cycles, the control and regulation measures include: (1) controlling the reduction or increase of the crimping rate and crimping amount through the crimping control module; (2) controlling the reduction or increase of the release rate and release amount through the warp feed control module; (3) controlling the increase or decrease of the weft-beating stroke and weft-beating force through the weft-beating control module; (4) controlling the increase or decrease of the shedding stroke through the shedding control module.

[0080] It should be emphasized that the above-mentioned control and adjustment measures (1) to (4) can achieve the same effect on the control and adjustment of fabric quality. The specific measures can be any one or more of them in combination.

[0081] In one embodiment, please refer to the appendix. Figure 3 As shown, if the actual weft density is larger than the theoretical weft density, it indicates a risk of fabric sparseness defects in this cycle. In this case, to ensure normal fabric quality in subsequent cycles, control and regulation measures can include:

[0082] (1) Reduce the curling rate and curling amount by curling control;

[0083] (2) Reduce the release rate and release amount by controlling the delivery process;

[0084] (3) Increase the weft insertion stroke and weft insertion force by controlling the weft insertion;

[0085] (4) Increase the opening stroke appropriately by controlling the opening mechanism.

[0086] Conversely, if the actual weft density is smaller than the theoretical weft density, it indicates a risk of fabric tightness defects in this cycle. In this case, to ensure normal fabric quality in subsequent cycles, control and regulation measures can include:

[0087] (1) Increase the curling rate and curling amount by controlling the curling;

[0088] (2) Increase the release rate and release amount by controlling the delivery process;

[0089] (3) Reduce weft insertion stroke and weft insertion force by controlling weft insertion;

[0090] (4) Reduce the opening stroke appropriately by controlling the opening mechanism.

[0091] In addition, to achieve the above objectives, the present invention also proposes a computer-readable storage medium, characterized in that the computer-readable storage medium stores a fabric quality control program, which, when executed by a processor, implements the steps of the fabric quality control method as described above.

[0092] The specific embodiments of the computer-readable storage medium of the present invention are basically the same as the embodiments of the application software security vulnerability detection method described above, and will not be repeated here.

[0093] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system.
