Description

Technical Field

[0001] The present application relates to the technical field of suturing equipment, and in particular to a suturing equipment and a sensor assembly thereof. Background Art

[0002] In rock wool board stitching applications, a sensor assembly is often required to monitor the tension of the weft thread to prevent it from breaking due to excessive tension when being pulled. It should be noted that since the tension required to break the weft thread is relatively low, if the sensor assembly has a low sensitivity, then when the sensor assembly detects that the tension exceeds the threshold, it is likely that the weft thread has already been broken. A high sensitivity of the sensor assembly also results in a high cost. Furthermore, in rock wool board stitching applications, the work site environment is often humid and dusty. The higher the sensitivity of the sensor assembly, the more likely it is to fail due to environmental interference. Summary of the Invention

[0065] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0066] It should be noted that, in the description of this application, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on this application.

[0067] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0068] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0069] Before understanding the embodiments proposed in this application, it should be clear that cotton thread is needed to sew the rock wool in the production process of the rock wool board to improve the mechanical strength of the rock wool board. Figure 1As shown (mature technology, so only the shuttle 3 is shown), the shuttle 3 is used to carry the weft 2 through multiple warp loops 1 at one time, thereby forming a continuous chain suture. This suturing method has the following defects. If the weft 2 breaks, all the suture structures on the corresponding suture chain of the rock wool board will fail (refer to the sealing suture structure of the nylon bag). During the tensile test of the material (for example, rock wool board), the material will always break at the weakest point in mechanical strength. If all the suture structures on a suture chain on the rock wool board fail, the tensile strength of the rock wool board at that point will drop by more than 50%. In order to avoid the weft 2 from breaking, the tension of the weft 2 needs to be monitored by a sensor assembly to avoid the weft 2 from breaking due to excessive tension.

[0070] In order to solve the technical problem that the existing sensor assembly is not suitable for the application scenario of rock wool board suturing, this application proposes an embodiment of a sensor assembly. In this embodiment, the sensor assembly 55 includes a body, a tension sensor 553, a first piston 555, a second piston 557, a pull rod 556 and a pull ring 559. Figure 10 As shown, a U-shaped through hole 551 is provided in the main body, and the U-shaped through hole 551 includes a first section, an arc section and a second section that are connected in sequence. The inner diameter of the first section is larger than the inner diameter of the second section. When in use, the openings of the first section and the second section in the U-shaped through hole 551 are both vertically facing upward; and there is a connecting fluid inside the U-shaped through hole 551. The first piston 555 is provided in the first section of the U-shaped through hole 551. The tension sensor 553 is provided in the main body, and the first piston 555 is connected to the tension sensor 553. The second piston 557 is provided in the second section of the U-shaped through hole 551. The first end of the pull rod 556 is connected to the end of the second piston 557 close to the opening of the second section, and the pull ring 559 is provided at the second end of the pull rod 556.

[0071] In this embodiment, the first piston 555 is arranged in the first section of the U-shaped through hole 551, which means that the first piston 555 can perform piston movement in the first section of the U-shaped through hole 551; similarly, the second piston 557 is arranged in the second section of the U-shaped through hole 551, which means that the second piston 557 can perform piston movement in the second section of the U-shaped through hole 551.

[0072] As will be seen below, the tension sensor 553 provided on the main body monitors the change in tension applied to the first piston 555. In this embodiment, there is no restriction on the location of the tension sensor 553. For example, the tension sensor 553 may be provided as follows: Figure 10 As shown, it is fixedly installed in the first section of the U-shaped through hole 551; it can also be as shown in FIG. Figure 17 As shown, it is fixedly installed on the top of the body.

[0073] During use, the weft 2 is passed through the pull ring 559. If the pulling force of the wire pulling device 4 pulling the weft 2 increases (that is, the tension of the weft 2 increases), the pull ring 559 can drive the second piston 557 through the pull rod 556 to generate a tendency to move along the U-shaped through hole 551 toward the direction of the second section opening (hereinafter referred to as the first movement direction). If the second piston 557 has a tendency to move along the first movement direction, that is, under the action of the second piston 557, the liquid level of the second section of the U-shaped through hole 551 has a tendency to rise (when the volume of the connected liquid in the U-shaped through hole 551 remains unchanged, that is, the pressure at the second section of the liquid surface has a tendency to decrease). Based on Pascal's law, it can be seen that when any point in an incompressible static fluid is subjected to an external force to generate a pressure increase, this pressure increase is instantaneously transmitted to all points in the static fluid. That is to say, in this embodiment, the pressure at the first section of the liquid surface has the same changing trend as the pressure at the second section of the liquid surface. If the pressure at the first section of the liquid surface changes, the force exerted on the first piston 555 will also change. Specifically, the force applied to the first piston 555 changes as follows:

[0074] F=ΔP*S

[0075] Wherein, F is the force change value exerted on the first piston 555 ; ΔP is the pressure change value at the first liquid level, which is equal to the pressure change value at the second liquid level; and S is the cross-sectional area of ​​the first section of the U-shaped through hole 551 .

[0076] From the above, it can be seen that when the inner diameter of the second section of the U-shaped through hole 551 remains unchanged and the tension on the pull ring 559 changes, if the inner diameter of the first section is larger, the force on the first piston 555 will theoretically change more.

[0077] In this embodiment, because the first piston 555 is connected to the tension sensor 553, if the force acting on the first piston 555 changes, the tension measured by the tension sensor 553 also changes accordingly (increases or decreases). In other words, in this embodiment, the tension detected by the tension sensor 553 can be amplified by having the inner diameter of the first section larger than the inner diameter of the second section. In other words, in this embodiment, a tension sensor 553 with lower sensitivity can be used, which not only saves costs but also prevents the tension sensor 553 from failing to detect small changes in the pull ring 559.

[0078] In this embodiment, the first piston 555 is connected to the tension sensor 553 so that when the tension on the first piston 555 changes, the tension sensor 553 can monitor the change in tension. In the embodiment of the present application, there is no limitation on the connection between the first piston 555 and the tension sensor 553. For example, the first piston 555 can be connected to the tension sensor 553 through a rope or a Figure 17 Of course, it is also possible to connect Figure 10 As shown, the sensor assembly further includes a first elastic member 554. The tension sensor 553, the first elastic member 554, and the first piston 555 are sequentially arranged vertically downward in the first section of the U-shaped through hole 551. One end of the first elastic member 554 is connected to the tension sensor 553, and the other end of the first elastic member 554 is connected to the first piston 555.

[0079] To ensure that the liquid levels in the first and second sections of the U-shaped through hole 551 can be quickly reset when the tension in the pull ring 559 is removed, in one embodiment of the present application, the sensor assembly may further include a second elastic member 558. The second elastic member 558 is disposed in the second section of the U-shaped through hole 551. The second elastic member 558 stores elastic potential energy, which tends to move the second piston 557 toward the bottom of the U-shaped through hole 551. During use, if the tension in the pull ring 559 is removed, the second elastic member 558 quickly resets the liquid levels in the first and second sections of the U-shaped through hole 551.

[0080] In this embodiment, the first piston 555 and / or the second piston 557 may be elastic sealing members. The elastic sealing members may be pistons made of elastic materials (eg, rubber, silicone, or foam, etc.).

[0081] In this embodiment, if Figure 10 As shown, a stopper is also provided at the opening of the second section to prevent the second piston 557 from being pulled away from the body by the pull rod 556. The stopper can be a cover with a through hole, through which the pull rod 556 is inserted to connect with the second piston 557. The cover matches the size and shape of the opening of the second section. In this embodiment, the cover can be threadedly connected to the body or integrally formed with the body.

[0082] In the embodiment of the present application, there are no excessive restrictions on the ratio of the inner diameter of the first section to the inner diameter of the second section (hereinafter referred to as the first ratio). It only needs to be able to appropriately amplify the tension change in the pull ring 559. For example, the first ratio can be 3, 4 or 5.

[0083] In the embodiments of the present application, the communication fluid can be any liquid capable of transmitting tension. For example, the communication fluid can be hydraulic oil or a fluorinated fluid. To enable the tension sensor 553 to quickly sense changes in tension in the pull ring 559, in the embodiments of the present application, the communication fluid in the U-shaped through hole 551 can be maintained at a slightly positive pressure (e.g., 0.11 MPa or 0.15 MPa).

[0084] In the embodiment of the present application, there are no excessive restrictions on the shape and structure of the first elastic member 554 (the same applies to the second elastic member 558 and the third elastic member 49). It is only necessary that the first elastic member 554 has elasticity and can transmit the change of the force applied to the first piston 555. For example, the first elastic member 554 can be a straight rod with elasticity, or a Figure 10 Springs etc. shown.

[0085] In the embodiment of the present application, there is no limitation on the connection method between the pull ring 559 and the pull rod 556. For example, the pull ring 559 and the pull rod 556 can be welded, integrally formed, or screwed.

[0086] It should be noted that the susceptibility of the weft thread 2 to breakage during the suturing process is also closely related to the release speed of the weft thread 2. In high-speed suturing applications, if the release speed of the weft thread 2 is slower than the pulling speed of the shuttle 3, the weft thread 2 is extremely likely to break. Based on this, in the embodiments of the present application, the release parameter may also include the speed at which the weft thread 2 is released. In other words, the sensor assembly 55 may also include a speed sensor for measuring the release speed of the weft thread 2.

[0087] In an embodiment of the present application, the sensor assembly 55 may further include a speed sensor.

[0088] It should be clear that if the sensor assembly 55 is a combination of a speed sensor and a tension sensor in the above embodiment, the tension sensor and the speed sensor need to be installed separately. There will be mutual interference between the two separately installed sensors. For example, the weft 2 is in contact with both the tension sensor and the speed sensor, which will definitely affect the tension or speed detection of the weft 2. In an environment with high humidity and a lot of dust, the separate tension sensor and speed sensor are also prone to failure. In order to solve this technical problem, in one embodiment of the present application, the main body is also provided with an intermediate through hole 552 and a pull rope sensor 53, and one end of the intermediate through hole 552 is connected to the U-shaped through hole 551. The inner diameter of the intermediate through hole 552 is smaller than the inner diameter of the second section of the U-shaped through hole 551. When in use, the opening at the other end of the intermediate through hole 552 is vertically upward, and the float in the pull rope sensor 53 is adapted to the intermediate through hole 552.

[0089] It should be clear that the pulling speed of the weft 2 is positively correlated with the moving distance of the second piston 557 along the first moving direction. That is to say, the greater the pulling speed of the wire pulling device 4 on the weft 2, the greater the pulling force on the pull ring 559, that is, the greater the moving distance of the pull ring 559 along the first moving direction (equal to the moving distance of the second piston 557 along the first moving direction). If the moving distance of the second piston 557 along the first moving direction is greater, the increase in the liquid level height of the second section of the U-shaped through hole 551 is greater. If the liquid level in the second section of the U-shaped through hole 551 rises, the liquid level height in the middle through hole 552 must drop. According to the principle of saving effort but not work, the piston with a smaller diameter (that is, the float of the rope sensor 53) moves a longer distance. Specifically, the calculation formula for the float moving distance of the rope sensor 53 is as follows:

[0090] D2=D1×(S1 / S2)

[0091] Here, D2 represents the distance traveled by the float of the pull-wire sensor 53; D1 represents the distance traveled by the second piston 557; S1 represents the cross-sectional area of ​​the second piston 557; and S2 represents the cross-sectional area of ​​the float of the pull-wire sensor 53. In the embodiment of the present application, because the inner diameter of the middle through hole 552 is smaller than the inner diameter of the second section of the U-shaped through hole 551 (i.e., the cross-sectional area of ​​the float is smaller than the cross-sectional area of ​​the second piston 557), the travel distance of the float is greater than the travel distance of the second piston 557.

[0092] That is, in this embodiment, even if the pulling speed of the weft thread 2 changes slightly (i.e., the pulling force on the pull ring 559 changes slightly), and thus the pull ring 559 only produces a slight change in distance (i.e., the second piston 557 produces a slight change in distance), as long as the ratio of the cross-sectional area of ​​the second piston 557 to the cross-sectional area of ​​the float (i.e., the ratio of the inner diameter of the second section of the U-shaped through hole 551 to the inner diameter of the middle through hole 552, hereinafter referred to as the second ratio) is large enough, the float of the pull rope sensor 53 can also produce a significant distance movement. In other words, in this embodiment, a pull rope sensor 53 with lower sensitivity can also be used, which can save costs and avoid the phenomenon that the pull rope sensor 53 cannot detect slight changes in the moving speed of the weft thread 2.

[0093] In the embodiment of the present application, the float in the drawstring sensor 53 is adapted to the middle through hole 552 in such a manner that the float can move freely within the middle through hole 552, and the communication fluid in the middle through hole 552 does not overflow from the gap between the float and the middle through hole 552. For example, the outer diameter of the float can be equal to the inner diameter of the middle through hole 552, or a sealing structure such as a sealing ring can be provided between the float and the middle through hole 552.

[0094] In this embodiment, there is no limitation on the size of the second ratio, as long as it can appropriately amplify the distance traveled by the float in the pull-wire sensor 53. For example, the second ratio can be 4, 6, or 8.

[0095] In this embodiment, during use, the weft thread 2 only needs to be in contact with the pull ring 559, and the tension sensor 553 and the rope sensor 53 can generate corresponding detection results through the connecting fluid in the U-shaped through-hole 551. Compared to the two sensors that both need to be in contact with the weft thread 2 to generate results, this embodiment does not cause large errors in the detection results due to excessive objects in contact with the weft thread 2. In addition, the sensing parts of the tension sensor 553 and the rope sensor 53 in the embodiment of the present application are both located in the sealed U-shaped through-hole 551. In other words, the sensing parts of the tension sensor 553 and the rope sensor 53 in this embodiment are not affected by the humidity and dust in the use environment and are not easily invalidated.

[0096] It should be noted that, during long-term use, if the communicating fluid in the U-shaped through-hole 551 decreases (e.g., due to volatilization loss or small leakage), the detection accuracy of the sensor assembly 55 may be affected. To prevent the detection accuracy of the sensor assembly 55 from being affected by the decrease in communicating fluid in the U-shaped through-hole 551, in one embodiment of the present application, the body is further provided with a liquid inlet pipe 56, which is connected to the U-shaped through-hole 551. The communicating fluid can be regularly replenished in the U-shaped through-hole 551 through the liquid inlet pipe 56.

[0097] In one embodiment of the present application, the liquid inlet pipe 56 is provided with a pressure reducing valve 57. The provision of the pressure reducing valve 57 ensures that, during the process of replenishing the communicating liquid into the U-shaped through hole 551, the pressure of the communicating liquid in the U-shaped through hole 551 is not affected by external pressure (e.g., the output pressure of the liquid inlet assembly 58), and can be maintained at a fixed value after the communicating liquid is replenished.

[0098] In order to automatically replenish the communication fluid into the U-shaped through hole 551, in one embodiment of the present application, Figure 11 As shown, the pay-off device 5 further includes a liquid inlet component 58 , which is used to inject communication liquid into the U-shaped through hole 551 through the liquid inlet pipe 56 .

[0099] In the embodiment of the present application, the liquid inlet component 58 can be any component or assembly that can inject the communication liquid into the U-shaped through hole 551. For example, the liquid inlet component 58 can be a pump or a gravity tower (refer to a water tower).

[0100] The sensor assembly embodiment proposed in this application, through the provision of a U-shaped through-hole, can amplify the tension of the weft thread through the connecting fluid in the U-shaped through-hole. Even using a tension sensor with low sensitivity, it can sensitively monitor slight changes in the tension of the weft thread. In addition, the tension sensor is located in the enclosed space of the U-shaped through-hole and is not easily affected by the external environment. In other words, the sensor assembly is not easily affected by environmental interference and fails. In other words, this sensor assembly is suitable for application scenarios such as rock wool board suturing.

[0101] Having introduced the sensor assembly proposed in the embodiment of this application, the following describes an embodiment of a suturing device proposed in this application. In this embodiment, the suturing device includes a sensor assembly 55 as described above. Specifically, the sensor assembly 55 can monitor the tension or speed of the weft thread 2 carried by the shuttle 3.

[0102] It should be understood that in the suturing device, the weft 2 carried by the shuttle 3 is released from the pay-off device 5. In the embodiment of the present application, there is no limitation on the pay-off device 5, as long as the pay-off device 5 can release the weft 2 under the pulling of the shuttle 3. For example, the pay-off device 5 can be as follows: Figure 7 As shown, it includes a pay-off wheel assembly 52, and the shuttle 3 is used to pull the weft 2, so the pay-off wheel in the pay-off wheel assembly 52 can rotate to release the weft 2 wound around it.

[0103] It is easy to understand that if Figure 7 As shown, if the pay-off wheel in the pay-off wheel assembly 52 is stuck, it is very easy to cause the weft 2 to break during the suturing process. As can be seen from the foregoing, if the weft 2 breaks, it will affect the mechanical strength of the rock wool board.

[0104] In order to solve the Figure 7 The pay-off device 5 shown in the figure has the problem that the weft 2 is easily broken if the pay-off wheel is stuck during use. The present application also proposes an embodiment of the pay-off device. In this embodiment, the pay-off device 5 includes a bottom plate 51 and two pay-off wheel assemblies 52. Figure 8 As shown, the two pay-off wheel assemblies 52 are both arranged on the bottom plate 51, and the head ends of the weft threads 2 wound by the two pay-off wheel assemblies 52 are connected. In the embodiment of the present application, the head ends of the weft threads 2 wound by the two pay-off wheel assemblies 52 are connected, which means that the weft threads 2 wound by the pay-off wheel assemblies 52 can be knotted together, or melted together, or the two pay-off wheel assemblies 52 can be wound around the same weft thread 2, etc.

[0105] In this embodiment, there are no particular restrictions on the placement of the two pay-off wheel assemblies 52. It is sufficient that the weft thread 2 stretched between the two pay-off wheel assemblies 52 is easily accessible for hooking the wire-pulling device 4 described below. For example, the stretching direction of the stretched weft thread 2 can be parallel to the extension direction of the telescopic portion of the telescopic assembly 42. The length of the stretched weft thread 2 can be 5 cm or 10 cm, for example.

[0106] In this application, if Figures 7 to 9 As shown, the pay-off wheel assembly 52 includes at least one pay-off wheel that can rotate, and the weft 2 is wound on the pay-off wheel. That is to say, in the embodiment of the present application, the pay-off wheel assembly 52 can be any assembly having a pay-off wheel that can rotate. The pay-off wheel assembly that can rotate is a mature technology and will not be listed in detail here. For example, the pay-off wheel assembly 52 can be as follows: Figure 7 As shown, it can also be the winding roller disclosed in the patent document with publication number CN222138363U, entitled: A yarn pay-off device capable of detecting broken yarn.

[0107] In this embodiment, the weft thread 2 will only break due to a stuck pay-off wheel if both pay-off wheels in the pay-off wheel assemblies 52 become stuck. Compared to a single pay-off wheel assembly 52 becoming stuck, the probability of both pay-off wheels 52 becoming stuck is lower. In other words, the provision of two pay-off wheel assemblies 52 in this embodiment reduces the probability of the weft thread 2 breaking due to a stuck pay-off wheel during the stitching process.

[0108] To further prevent the weft 2 from being broken due to the weft reel in the pay-off wheel assembly 52 becoming stuck, in one embodiment of the present application, the pay-off device 5 further includes a sensor assembly 55 corresponding to each pay-off wheel assembly 52 and a resistance motor 54 corresponding to each pay-off wheel assembly 52. ​​The sensor assembly 55 is at least used to measure the release parameter when the corresponding pay-off wheel assembly 52 releases the weft 2, and the release parameter may include the tension when releasing the weft 2. As mentioned above, the weft 2 must be pulled by an external force (i.e., the weft 2 is pulled by the wire pulling device 4) in order to rotate the corresponding pay-off wheel in the pay-off wheel assembly 52 and release the weft 2. In other words, in this embodiment, the weft 2 can only be released normally if the pulling force applied to the weft 2 (i.e., the tension when releasing the weft 2) is greater than the resistance to the rotation of the pay-off wheel in the pay-off wheel assembly 52. ​​In other words, if the resistance to the rotation of the pay-off wheel is greater than the maximum tension that the weft 2 can withstand, the weft 2 is easily broken. In this embodiment, the resistance motor 54 is provided in the corresponding pay-off wheel assembly 52 and is used to adjust the release speed of the weft thread 2 of the pay-off wheel assembly 52 (i.e., adjust the rotation speed of the pay-off wheel) based on the release parameter. In other words, if the rotational resistance of the pay-off wheel in the pay-off wheel assembly 52 is large, the resistance motor 54 is activated to reduce the resistance of the pay-off wheel assembly 52 to release the weft thread 2, thereby preventing the weft thread 2 from being broken due to excessive tension.

[0109] It should be understood that controlling the rotation speed of the rotating body (the pay-off wheel in the pay-off wheel assembly 52) by means of a motor (ie, the resistance motor 54) is a mature technology and will not be described in detail here.

[0110] During use, if the sensor assembly 55 measures that the tension when releasing the weft thread 2 is greater than the third threshold, the resistance motor 54 can be used to rotate the pay-off wheel to promote the release of the weft thread 2, thereby avoiding excessive tension in the weft thread 2 and causing the weft thread 2 to break.

[0111] In the embodiment of the present application, the third threshold can be set according to needs, for example, the third threshold can be 8N or 9N.

[0112] In an embodiment in which the sensor assembly 55 is capable of monitoring the release speed of the weft thread 2, when in use, if the sensor assembly 55 measures that the speed of releasing the weft thread 2 is less than the fourth threshold value, the resistance motor 54 can be used to rotate the pay-off wheel to promote the release of the weft thread 2, thereby avoiding the weft thread 2 from breaking due to the release speed being too low.

[0113] In the embodiment of the present application, the fourth threshold value can be set according to needs, for example, the fourth threshold value can be 8 mm / s or 10 mm / s.

[0114] In the production process of rock wool board, cotton thread is needed to sew the rock wool to improve the mechanical strength of the rock wool board. Figure 1 As shown (mature technology, so only the shuttle 3 is shown), the shuttle 3 is used to carry the weft 2 on the pay-off device 5 through multiple warp loops 1 at one time, thereby forming a continuous chain suture. This suturing method has the following defects. If the weft 2 breaks, the suture structure of the entire row on the rock wool board will fail (refer to the sealing suture structure of the nylon bag). In order to solve this technical problem, the present application proposes an embodiment of a suturing device. Specifically, the suturing device includes: a pay-off device 5 corresponding to each warp loop 1, and a wire pulling device 4 corresponding to each pay-off device 5. When in use, the wire pulling device 4 is used to carry the weft 2 in the corresponding pay-off device 5 through the corresponding warp loop 1. That is to say, during the suturing process, each warp loop 1 corresponds to a wire pulling device 4 and a pay-off device 5.

[0115] During use, the weft 2 in the pay-off device 5 is passed through the corresponding warp ring 1 through the wire pulling device 4. That is to say, the wire pulling device 4 can make each weft 2 pass through only one warp ring 1. After suturing, the various suture structures on the rock wool board are independent of each other. Even if a certain weft breaks, it will not affect the other suture structures. Compared with the prior art, if a single weft 2 breaks, the tensile strength of the rock wool board will drop by more than 50%. After the rock wool board is suturing with the suturing device in this embodiment, if any one of the wefts 2 breaks, the effect on the tensile strength of the rock wool board is less than 10% (that is, the tensile strength of the rock wool board remains above 90%).

[0116] In the embodiment of the present application, there are no excessive restrictions on the wire pulling device 4. It is only necessary that the wire pulling device 4 can pass the weft thread on the wire paying-off device 5 through the corresponding warp thread loop 1 during the suturing process. For example, the wire pulling device 4 can be a manually controlled hook, and each time suturing is performed, the weft thread 2 on the wire paying-off device 5 is passed through the corresponding warp thread loop 1 by manually controlling the hook.

[0117] In order to automatically pass the weft 2 on the pay-off device 5 through the corresponding warp ring 1, in one embodiment of the present application, the wire pulling device 4 may include a bracket 41, a telescopic component 42, a hanging component and a clamping component. Figure 2 As shown, the telescopic assembly 42 is mounted on the bracket 41. The hooking assembly is mounted at the output end of the telescopic assembly 42. The hooking assembly has an engaged state and a released state. When the hooking assembly is in the engaged state, it can be hooked to the weft thread 2 stretched in the pay-off device 5; when the hooking assembly is in the released state, the hooking to the weft thread 2 is released.

[0118] In this embodiment, the output end of the telescopic component 42 refers to the part of the telescopic component 42 that can be telescoped. The output end of the piston cylinder (that is, the piston rod in the piston cylinder) mentioned below is also the same, and will not be described in detail later.

[0119] When using, such as Figure 2 As shown, first the telescopic assembly 42 is extended, and then the extended telescopic assembly 42 can carry the hanging assembly through the corresponding warp ring 1; then the hanging assembly is switched from the released state to the hanging state, that is, the hanging assembly is hung with the straightened weft 2 in the pay-off device 5; further, the telescopic assembly 42 is shortened. Since the hanging assembly is hung with the straightened weft 2 in the pay-off device 5, if the telescopic assembly 42 is shortened, the hanging assembly can carry the weft 2 through the warp ring 1; after the weft 2 passes through the warp ring 1, the needle and thread loop can be withdrawn for tightening and sewing (withdrawing the needle and thread loop for tightening and sewing is a mature technology and will not be described here). After the needle and thread loop tightening and sewing step is completed, the hanging assembly is switched from the hanging state to the released state, thereby releasing the connection between the hanging assembly and the weft 2.

[0120] It should be noted that only when the weft 2 is in a straight state can it be easily connected to the hanging assembly. After the straightened weft 2 is carried by the hanging assembly through the warp loop 1, it is difficult for the weft 2 released by the pay-off device 5 to maintain a straight state. In other words, in the next round of needle and thread loop tightening and suturing steps, it is difficult to make the weft 2 pass through the warp loop 1 through the hanging assembly. In order to make the weft 2 in a non-straightened state pass through the warp loop 1 in the next round of needle and thread loop tightening and suturing steps, the clamping assembly in this embodiment is also required. In this embodiment, the clamping assembly is also arranged at the output end of the telescopic assembly 42. The clamping assembly has a clamping state and a releasing state; when the clamping assembly is in the clamping state, it can clamp the weft 2 drawn out from the pay-off device 5; when the clamping assembly is in the releasing state, it can release the clamping of the weft 2.

[0121] When using, such as Figure 2 As shown, if it is necessary to use the wire pulling device 4 to pass the non-straightened weft 2 in the pay-off device 5 through the corresponding warp loop 1, the telescopic assembly 42 is first extended, and then the extended telescopic assembly 42 can carry the clamping assembly through the corresponding warp loop 1; then the clamping assembly switches from the released state to the clamping state, that is, the clamping assembly can clamp the non-straightened weft 2 in the pay-off device 5; further, the telescopic assembly 42 is shortened. Since the clamping assembly clamps the non-straightened weft 2, if the telescopic assembly 42 is shortened, the clamping assembly can carry the weft 2 through the warp loop 1. After the weft 2 passes through the warp loop 1, the needle and thread loop can be withdrawn for tightening and sewing. After the needle and thread loop tightening and sewing steps are completed, the clamping assembly switches from the clamping state to the released state, thereby releasing the clamping of the weft 2.

[0122] In the embodiments of the present application, there are no excessive restrictions on the shape and structure of the bracket 41. It is only necessary that the bracket 41 can fix and support the telescopic assembly 42. For example, the shape and structure of the bracket 41 can be designed based on the suturing device so that it is convenient to fix the bracket 41 to the suturing device when in use; the shape and structure of the bracket 41 can also be designed based on the site or other equipment around the suturing device so that it is convenient to fix the bracket 41 to these sites or equipment when in use. It should be noted that adaptive design of the shape or structure of a product (e.g., the bracket 41, the liquid inlet assembly 58, the inflatable component and the negative pressure component, etc.) based on the installation environment of the product is a mature technology and will not be listed in detail here. For example: to facilitate the threaded connection between the bracket 41 and the suturing device, a threaded hole is pre-set on the bracket 41; or, to reduce the weight of the bracket 41, the bracket 41 is set to a hollow shape; or, based on the structure of the suturing device, the shape and structure of the bracket are set (for example, if the suturing device has a flat surface, the bracket can be set to a plate-like structure that can fit the flat surface).

[0123] As can be seen from the foregoing, in this embodiment, the telescopic assembly is primarily used to carry the hook assembly and the clamping assembly in linear reciprocating motion, thereby inserting and exiting the corresponding warp loop 1. In other words, in the embodiments of this application, there are no additional restrictions on the telescopic assembly; it only needs to be able to carry the hook assembly and the clamping assembly in linear reciprocating motion. In other words, the telescopic assembly can be any commercially available component that can extend and retract, for example, an electric push rod, a hydraulic push rod, or a pneumatic cylinder.

[0124] In the embodiment of the present application, the hanging component can be any component that can be hung with the stretched weft 2 (i.e., the hanging component is in the hanging state) and released (i.e., the hanging component is in the released state). For example, the hanging component can be a hook provided at the output end of the telescopic component 42, or a hook provided at the output end of the telescopic component 42. Figures 4 to 6 Components shown.

[0125] In the application scenario where the hanging component is a hook, when in use, if it is necessary to use the hanging component to pass the straightened weft thread 2 through the warp ring 1, then after the hook at the output end of the telescopic component 42 (that is, the hanging component) passes through the warp ring 1, the straightened weft thread 2 can be manually hung on the hook (that is, the hanging component is manually switched from the released state to the hung state); after the current sewing step is completed, the weft thread 2 on the hook is manually removed (that is, the hanging component is manually switched from the hung state to the released state).

[0126] In order to enable the hook assembly to automatically switch from the release state to the hook state or from the hook state to the release state, in one embodiment of the present application, the hook assembly includes a power gear 43, a gear ring 44, a hook 45 and a driving member. Figure 3 As shown, a power gear 43 and a gear ring 44 are both rotatably mounted on the output end of the telescopic assembly 42, and the power gear 43 and the gear ring 44 are meshed. A hook 45 is mounted on the gear ring 44 and is used to engage the stretched weft thread 2 in the pay-off device 5. A driving member is used to drive the power gear 43 to rotate.

[0127] In this embodiment, when the hanging component is in the hanging state, Figure 4 As shown, when the hook component is in the released state, Figure 5 When in use, when the telescopic assembly is fully extended, if the hook assembly needs to be automatically switched from the released state to the hooked state, the driving member can drive the power gear 43 to rotate; since the power gear 43 and the gear ring 44 are meshed, if the power gear 43 rotates, the gear ring 44 also rotates; since the hook 45 is provided on the gear ring 44, if the gear ring 44 rotates, the hook 45 can be Figure 5 The position in the changes to Figure 4 That is to say, in this embodiment, if the hook assembly needs to be automatically switched from the release state to the hook state, it is only necessary to drive the hook 45 from the release state to the hook state. Figure 5 The position in the changes to Figure 4 Similarly, if the hook assembly needs to be automatically switched from the hook state to the release state, it is only necessary to drive the hook 45 from the Figure 4 The position in the changes to Figure 5 The position in the middle can be used.

[0128] Specifically, the process of switching the mounting component from the release state to the mounting state is as follows:

[0129] like Figure 13 As shown, the hanging assembly is at a certain distance from the stretched weft 2, and the hook 45 and the stretched weft 2 are not connected (i.e., the hanging assembly is in a released state). First, the output end of the telescopic assembly 42 is used to control the hanging assembly to move along the direction shown in FIG. Figure 13 Direction A in the middle is close to the straightened weft 2 until Figure 14 As shown, the straightened weft 2 is located in the ring formed by the gear ring 44; further, the gear ring 44 is driven by the power gear 43 along the Figure 14 The hook 45 and the straightened weft thread 2 are rotated in the direction C of Figure 15 As shown; finally, as Figure 15 As shown, through the output end of the telescopic component 42, the hanging component is controlled to move along Figure 15In the process of the hook assembly retreating, the hook 45 and the weft 2 can always form a Figure 4 The hook shown (that is, the hook component is in the hooked state).

[0130] Specifically, the process of switching the attachment state to the release state is as follows:

[0131] As can be seen from the above, when controlling the hook component along Figure 15 The direction B in the middle is retreated until the weft 2 passes through the corresponding warp ring 1 (the hook assembly is still in the hook state), and then the gear ring 44 is driven by the power gear 43 along the same direction. Figure 4 Rotate in the direction D until Figure 5 As shown, the weft thread 2 is disengaged from the hook 45 (ie, the hook assembly is in a released state).

[0132] In the embodiments of the present application, the power gear 43 or the gear ring 44 can be rotatably disposed at the output end of the telescopic assembly 42 in any reasonable manner. For example, the power gear 43 may be fixedly provided with a rotating shaft, and the power gear 43 may be rotatably connected to the output end of the telescopic assembly 42 via the rotating shaft; or the rotating shaft may be fixedly provided at the output end of the telescopic assembly 42, and the power gear 43 may be rotatably connected to the output end of the telescopic assembly 42 via a rotating shaft fixed to the output end of the telescopic assembly 42. It should be understood that the rotatable connection between a gear (i.e., the power gear 43 or the gear ring 44) and an object (i.e., the output end of the telescopic assembly 42) is a mature technology and will not be elaborated on in detail here.

[0133] In the embodiment of the present application, there is no limitation on the shape and structure of the hook 45, as long as the hook 45 can be hooked with the stretched weft 2. For example, the weft 2 can be V-shaped or Figure 4 In this embodiment, there are no restrictions on the relative positions and connection methods of the hook 45 and the gear ring 44. It is only necessary that the hook 45 can be connected to the stretched weft 2. For example, the hook 45 can be welded or screwed to the gear ring 44; or Figure 4 The gear ring 44 is a semicircular ring, and the hook 45 extends from a notch of the gear ring 44 .

[0134] In the embodiment of the present application, the driving member can be any component that can drive the power gear 43 to rotate. For example, the driving member can be a micro motor. It is a mature technology to drive the gear (i.e., the power gear 43) to rotate by a motor, which will not be described in detail here. In order to make the overall structure of the wire pulling device 4 smaller, the driving member can be a magnetic drive member. It is a mature technology to magnetically drive a rotor (i.e., the power gear 43), which will not be described in detail here.

[0135] In the embodiments of the present application, the clamping assembly can be any assembly capable of clamping the non-straightened weft thread 2 (i.e., the clamping assembly is in a clamping state) and releasing the weft thread 2 (i.e., the clamping assembly is in a released state). For example, the clamping assembly can be the clamping assembly disclosed in patent publication number CN221587588U, entitled "A Clamping Assembly for a Tractor," or the clamping assembly disclosed in patent publication number CN119927882A, entitled "Automated Manipulator Clamping Mechanism and Fixture Including the Same."

[0136] As can be seen from the foregoing, only after the output end of the telescopic assembly 42 successfully carries the clamping assembly through the warp loop 1, can the clamping assembly be used to clamp the non-straightened weft 2 to pass through the warp loop 1. In other words, if the clamping assembly cannot pass through the warp loop 1 smoothly, the weft 2 will definitely not be able to pass through the warp loop 1 during the suturing process. If the weft 2 cannot pass through the warp loop 1, a suture structure cannot be formed, that is, the rock wool cannot be sutured. It should be noted that the more complex the structure of the clamping assembly, the larger the size of the clamping assembly. During the suturing process of the rock wool, the size of the warp loop 1 formed is limited. If the size of the warp loop 1 formed remains unchanged, the larger the size of the clamping assembly, the more difficult it is for the clamping assembly to pass through the warp loop 1.

[0137] In order to simplify the structure of the clamping assembly, reduce the size of the clamping assembly, and make it easier for the clamping assembly to pass through the warp loop 1, in one embodiment of the present application, the clamping assembly includes an inflatable member (not shown in the figure) and two airbags 46. The two airbags 46 are arranged at the output end of the telescopic assembly 42. When the clamping assembly is in the clamping state, the minimum distance between the two airbags 46 is 0 (that is, the airbags 46 are inflated); when the clamping assembly is in the released state, the minimum distance between the two airbags 46 is at least greater than the diameter of the weft 2 (that is, the airbags 46 are not inflated). The inflatable member is connected to the two airbags 46, and the inflatable member is at least used to fill gas into the two airbags 46.

[0138] In this embodiment, when the clamping assembly is in the released state, Figure 5 As shown (i.e., the airbag 46 is not inflated); when the clamping assembly is in the clamping state, as shown Figure 6As shown (that is, the airbags 46 are inflated). During use, if the clamping assembly is in the released state, the volume of the two airbags 46 is small, that is, the size of the clamping assembly is small, which makes it easier for the telescopic assembly 42 to carry the clamping assembly through the warp ring 1. When the telescopic assembly is extended to the right length (that is, the part with the clamping function in the clamping assembly at least passes through the warp ring 1), if it is necessary to clamp the unstretched weft 2 on the pay-off device 5, it is only necessary to inflate the two airbags 46 through the inflatable part. If the two airbags 46 are inflated, the distance between the two airbags 46 will be 0 after the two airbags 46 are inflated and expanded, and the weft 2 located between the two airbags 46 can be clamped. If it is necessary to release the clamping of the weft 2, the gas filled in the airbags 46 can be released.

[0139] In the embodiment of the present application, there is no limitation on the type of gas filled in the airbag 46 , for example, the gas may be air or nitrogen.

[0140] In the embodiment of the present application, there are no excessive restrictions on the shape and structure of the airbags 46. It is only necessary that the two airbags 46 can smoothly clamp the weft 2 after being inflated.

[0141] In the embodiment of the present application, the inflatable component can be any component that can inflate the airbag 46. For example, the inflatable component can be an air pump or an air compression tank.

[0142] As can be seen from the foregoing, in the embodiment of the present application, if the airbags 46 are inflated, the two airbags 46 can clamp the weft 2 (that is, the clamping assembly switches from a released state to a clamped state); if the gas in the airbags 46 is released, the two airbags 46 can release the clamping of the weft 2 (that is, the clamping assembly switches from a clamped state to a released state). In order to facilitate the switching of the two airbags 46 from a clamped state to a released state, in the embodiment of the present application, the inflatable member can be an inflatable pump for both inflation and suction; or, the airbag 46 is elastic, and the airbag 46 is provided with an electronic deflation valve. It should be understood that the inflatable pump for both inflation and suction and the electronic valve (that is, the electronic deflation valve) are both mature technologies and will not be elaborated here.

[0143] During use, if the inflatable member is a dual-purpose inflating and suctioning air pump, the airbag 46 can be expanded by inflating the air pump; and the airbag 46 can be deflated by the inflating pump. If the inflatable member can only inflate but not deflate, and the airbag 46 is elastic and equipped with an electronic deflation valve, the inflatable member can inflate the airbag 46; and the elastic airbag 46 can be automatically deflated by opening the electronic deflation valve.

[0144] In other embodiments of the present application, the clamping assembly can be as follows: Figure 16As shown, it includes two electromagnets 48. A plurality of third elastic members 49 are provided between each electromagnet 48 and the output end of the telescopic assembly 42. Before power is applied, the minimum distance between the two electromagnets 48 (i.e., Figure 16 The spacing d) is greater than the diameter of the weft 2, and the direction of the minimum spacing is perpendicular to the direction of extension of the output end of the telescopic component 42 (ie, as shown in FIG. Figure 16 When energized, the two electromagnets 48 overcome the elastic forces of the third elastic members 49 and attract each other (i.e., the minimum distance between the two electromagnets 48 becomes 0), thereby clamping the weft thread 2. When energized, the two electromagnets 48 return to their original positions under the elastic forces of the third elastic members 49, thereby releasing the grip on the weft thread 2.

[0145] As can be seen from the foregoing, the state switching of the hanging component and the clamping component is performed after the length of the telescopic component 42 is extended or shortened to a fixed position. For example, the switching of the hanging component from the released state to the hanging state or the control of the clamping component from the released state to the clamping state is performed after the output end of the telescopic component 42 carries the hanging component and the clamping component to a fixed position (that is, the length of the telescopic component mentioned above is extended to the position). In order to accurately determine the stroke of the telescopic component 42 for control, in one embodiment of the present application, the wire pulling device 4 may also include a switch component 47, which is at least used to control the stroke of the telescopic part of the telescopic component 42.

[0146] In the embodiments of the present application, there are no significant restrictions on the type of switch assembly 47. That is, the switch assembly 47 can be any suitable commercially available switch capable of controlling the travel of the telescopic assembly 42. For example, the switch assembly 47 can be a travel switch. The switch assembly 47 can include a first travel switch. When the first travel switch is touched during the extension of the telescopic assembly 42, the telescopic assembly 42 can stop extending. Of course, the switch assembly 47 can also include a second travel switch. When the second travel switch is touched during the contraction of the telescopic assembly 42, the telescopic assembly 42 can stop contracting.

[0147] As can be seen from the foregoing, if the switch assembly 47 is a travel switch, at least two travel switches (i.e., a first travel switch and a second travel switch) are required to determine whether the telescopic assembly 42 is fully shortened or fully extended. In an automatic control system, as the number of electronic devices (e.g., travel switches) increases, the structure and function of the automatic control system become more complex. This leads to an increase in the interactions and dependencies between the various parts of the automatic control system, making the operation and maintenance of the entire automatic control system more difficult. In addition, each electronic device itself may have potential failure points. As the number of electronic devices in the automatic control system increases, the probability of failure also increases accordingly. Moreover, the failure of one electronic device may affect the normal operation of other electronic devices, thereby affecting the stability of the entire automatic control system. In order to reduce the number of travel switches used and thereby improve the stability of the automatic control of the wire pulling device 4 in this embodiment, in one embodiment of the present application, the switch assembly 47 may include a piston cylinder, a piston rod, a vacuum sensor, and a controller. The piston cylinder is disposed on the bracket 41, and the piston cylinder and the piston rod are movably connected. The piston rod is connected to the telescopic part of the telescopic assembly 42. The vacuum sensor is used to measure the air pressure value inside the piston cylinder; the controller is used to control the stroke of the telescopic part in the telescopic assembly 42 based on the air pressure value.

[0148] During use, because the piston rod is connected to the output end of the telescopic assembly 42 (i.e., the telescopic portion of the telescopic assembly 42), if the output end of the telescopic assembly 42 extends, the piston rod also extends under the influence of the output end of the telescopic assembly 42, that is, the internal space of the piston cylinder increases, and the air pressure inside the piston cylinder decreases; if the output end of the telescopic assembly 42 shortens, the piston rod also shortens under the influence of the output end of the telescopic assembly 42, that is, the internal space of the piston cylinder decreases, and the air pressure inside the piston cylinder increases. In other words, in the embodiment of the present application, the air pressure inside the piston cylinder is measured by a vacuum sensor, and then it is determined whether the telescopic assembly 42 has fully shortened or fully extended based on the air pressure inside the piston cylinder.

[0149] In a specific embodiment of the present application, if the air pressure inside the piston cylinder is less than the first preset value, it can be considered that the telescopic component 42 is extended into place; if the air pressure inside the piston cylinder is greater than the second preset value, it can be considered that the telescopic component 42 is shortened into place.

[0150] In the embodiments of the present application, the first preset value and the second preset value can be set as needed, that is, there is no limitation on the setting of the first preset value and the second preset value in the present application. For example, the first preset value can be 0.5 atmospheres; the second preset value can be 1.5 atmospheres.

[0151] In the embodiments of the present application, there are no restrictions on the installation locations of certain components (e.g., the switch assembly 47, the liquid inlet assembly 58, the inflatable component, and the negative pressure component). In other words, the locations of these components can be set as needed. For example, in the embodiments of the present application, the switch assembly 47 can be installed on the bracket 41 or on the suturing device. The same applies to other components, and no further details will be given below.

[0152] As can be seen from the above, if the hanging assembly or the clamping assembly cannot successfully pass through the warp loop 1, the subsequent rock wool cannot be successfully sutured. It is easy to understand that if the warp threads constituting the warp loop 1 are offset or not fully unfolded, it is difficult for the hanging assembly or the clamping assembly to successfully pass through the warp loop 1. In order to make the warp threads constituting the warp loop 1 fully unfolded, and thus facilitate the hanging assembly or the clamping assembly to pass through the warp loop 1, in one embodiment of the present application, the suturing device may further include a negative pressure box 6 and a negative pressure member 7. Figure 12 As shown, the negative pressure box 6 is provided with a plurality of strip-shaped holes 61. Each strip-shaped hole 61 extends along a first direction, which is parallel to the direction of extension of the meridian. The input end of the negative pressure member 7 is connected to the interior of the negative pressure box 6. The negative pressure member 7 is used to create a negative pressure inside the negative pressure box 6.

[0153] During use, negative pressure is generated inside the negative pressure box 6 by the negative pressure member 7. Under the action of the negative pressure, a large amount of air around the strip-shaped holes 61 flows into the negative pressure box 6. Since the warp threads are relatively soft, the flowing air can "straighten" the warp threads during the process of a large amount of air around them flowing into the negative pressure box 6, that is, the warp thread loops 1 are fully expanded.

[0154] In an embodiment of the present application, the negative pressure member 7 can be any device that can extract the air inside the negative pressure box 6 (that is, form a negative pressure inside the negative pressure box 6), for example: the negative pressure member 7 can be a vacuum pump or a blower, etc.

[0155] In the embodiment of the suturing device proposed in this application, the sensor assembly in the suturing device is configured with a U-shaped through-hole. This can amplify the tension borne by the weft thread through the communicating fluid in the U-shaped through-hole. Even with a tension sensor of lower sensitivity, it can sensitively monitor slight changes in the tension borne by the weft thread. Furthermore, the tension sensor is located within the confined space of the U-shaped through-hole and is not easily affected by the external environment. This means that the sensor assembly is not susceptible to failure due to environmental interference. In other words, the sensor assembly is suitable for rock wool board suturing applications.

[0156] It should be understood that the present application only uses the rock wool sewing application scenario as an example to illustrate the sewing device in the present application, which does not mean that the sewing device proposed in the present application can only be used in the rock wool sewing application scenario. It should be understood that the sewing device proposed in the present application is applicable to any sewing application scenario, for example, the sewing device proposed in the present application can be used in carpet sewing, clothing sewing, aerogel felt sewing, inorganic fiber-molded boards, felts and rolls sewing, and other application scenarios.

[0157] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
