Description

Technical Field

[0001] The utility model relates to the field of textiles, in particular to an online detection line pressure adjustment device. Background Art

[0002] At present, thread adjusters are needed in sewing machines, embroidery machines, winding machines and other textile equipment in the textile field. The thread adjusters are used to adjust the tightness of the embroidery thread. The embroidery thread cannot be too tight or too loose.

[0003] For example, the embroidery thread passing through the needle in an embroidery machine needs to maintain appropriate tightness. If the embroidery thread is too tight, the fabric will be pulled loose by the embroidery thread during the embroidery process, and even holes will appear under the pulling of the embroidery thread, affecting the quality of the embroidery; if the embroidery thread is too loose, the embroidery thread of the embroidery pattern will be loose, seriously reducing the quality of the embroidery; therefore, a thread adjuster is needed.

[0004] In the winding machine, the embroidery thread needs to pass through the thread adjuster first, and the tightness of the embroidery thread is adjusted by the thread adjuster, and then it passes through a series of wire structures and is wound on the bobbin.

[0005] Currently, thread adjusters used in sewing machines, embroidery machines, and bobbin winding machines typically utilize a combination of two thread pressers, a spring, and a thread press knob. The two thread pressers hold the embroidery thread in place, and the thread press knob is manually rotated to adjust the pressure exerted by the spring on the thread pressers and the thread, thereby adjusting the tension of the thread wound around the bobbin. This type of thread adjuster has the following drawbacks: Operators rely on experience and feel to adjust the thread tension, resulting in poor precision and consistency in thread tension adjustment, which can hinder textile quality. Furthermore, excessive pressure from the thread pressers can lead to thread breakage. Utility Model Content

[0006] The purpose of the utility model is to provide an online detection line pressure adjustment device which can ensure the accuracy and consistency of embroidery thread tightness adjustment, thereby improving textile quality.

[0007] The technical solution of the utility model is:

[0008] An online detection line pressure adjustment device, comprising:

[0009] Bracket;

[0010] A guide rod is directly or indirectly provided on the bracket;

[0011] A limiting component movable along the guide rod, wherein the limiting component is connected to the guide rod via a connecting structure;

[0012] The wire pressing surface and the first wire pressing piece, the first wire pressing piece slides along the guide rod;

[0013] The elastic element is located between the first pressing piece and the limiting component, and the first pressing piece is pressed against the pressing surface under the action of the elastic element;

[0014] The line pressure detection sensor detects the pressing force of the elastic element acting between the first line pressing piece and the line pressing surface. The embroidery thread passes between the first line pressing piece and the line pressing surface, and the embroidery thread is pressed between the first line pressing piece and the line pressing surface. In the process of adjusting the compression amount of the elastic element by moving the limiting component and then adjusting the pressing force between the first line pressing piece and the line pressing surface, the line pressure detection sensor detects the pressing force between the first line pressing piece and the line pressing surface in real time. When the pressing force between the first line pressing piece and the line pressing surface measured by the line pressure detection sensor reaches the set value, the limiting component is stopped from moving and the limiting component is connected to the guide rod through the connecting structure, thereby accurately adjusting the pressing force between the first line pressing piece and the line pressing surface, ensuring the accuracy and consistency of the embroidery thread tightness adjustment, and improving the textile quality. At the same time, it can also effectively avoid the problem of thread breakage caused by excessive pressing force of the line pressing piece due to poor pressing force adjustment accuracy.

[0015] As a preference, it further includes a force transmission element and a second line pressure piece, the line pressure detection sensor is directly or indirectly arranged on the bracket, and the force transmission element is connected to the line pressure detection sensor.

[0016] The second pressing piece can slide along the guide rod, and the side of the second pressing piece facing the first pressing piece constitutes the pressing surface, and the second pressing piece is pressed against the force transmission element under the action of the elastic element;

[0017] Alternatively, the second thread pressing piece is fixed to the force transmission element, and the side of the second thread pressing piece facing the first thread pressing piece constitutes the thread pressing surface. In this way, the first thread pressing piece and the second thread pressing piece cooperate to compress the embroidery thread. The first thread pressing piece and the second thread pressing piece can be manufactured separately, which facilitates improving the smoothness of the thread pressing surface in contact with the embroidery thread. On the other hand, the pressing force of the elastic element acting between the first thread pressing piece and the thread pressing surface is transmitted to the line pressure detection sensor through the force transmission element, which is conducive to adjusting the layout of the line pressure detection sensor, guide rod, thread pressing surface and first thread pressing piece as needed during actual production.

[0018] Preferably, a force transmission element is further included, and the line pressure detection sensor is directly or indirectly arranged on the bracket, the force transmission element is connected to the line pressure detection sensor, and the side of the force transmission element facing the first line pressure piece constitutes the line pressure surface. In this way, the second line pressure piece can be omitted, reducing production costs. On the other hand, the pressing force of the elastic element acting between the first line pressure piece and the line pressure surface is transmitted to the line pressure detection sensor through the force transmission element, which is conducive to adjusting the layout of the line pressure detection sensor, the guide rod, the line pressure surface and the first line pressure piece as needed in actual production.

[0019] Preferably, the force transmission element is provided with a guide rod through-hole, the guide rod passing through the guide rod through-hole, and the first wire pressing piece, the elastic element, and the limiting component are all located on the same side of the guide rod through-hole. In this way, the pressing force exerted by the elastic element between the first wire pressing piece and the wire pressing surface can be stably transmitted to the wire pressure detection sensor through the force transmission element.

[0020] Preferably, the limiting component is a knob, and the knob is connected to the guide rod via a threaded connection, and the threaded connection structure between the knob and the guide rod forms the connection structure. In this way, when an operator adjusts the compression of the elastic element by turning the knob (rotating and moving the limiting component), and further adjusts the pressing force between the first thread pressing piece and the thread pressing surface, the pressing force between the first thread pressing piece and the thread pressing surface is detected in real time by the thread pressure detection sensor. When the pressing force between the first thread pressing piece and the thread pressing surface measured by the thread pressure detection sensor reaches a set value, the knob is stopped from being turned, thereby accurately adjusting the pressing force between the first thread pressing piece and the thread pressing surface, ensuring the accuracy and consistency of the embroidery thread tension adjustment, and improving the textile quality.

[0021] Preferably, the knob is a manual knob, which facilitates the production of the online detection line pressure adjustment device and reduces production costs.

[0022] Preferably, the knob is driven by a drive motor, which is mounted on a bracket and drives the knob to rotate. In this manner, the drive motor can be used to rotate the knob to automatically adjust the pressing force between the first thread pressing piece and the thread pressing surface. When the thread pressure detection sensor measures the pressing force between the first thread pressing piece and the thread pressing surface and reaches a set value, the drive motor stops rotating the knob, thereby automatically and accurately adjusting the pressing force between the first thread pressing piece and the thread pressing surface. This further ensures the accuracy and consistency of thread tension adjustment, thereby improving textile quality. Furthermore, this can reduce labor costs.

[0023] Preferably, the device further comprises a mounting member disposed on the bracket, the guide rod being disposed on the mounting member, and the line pressure detection sensor being also disposed on the mounting member. Thus, the module of the online detection line pressure adjustment device can be centrally mounted on the mounting member. Thus, during actual production, the module of the online detection line pressure adjustment device can be manufactured first, and then the mounting member can be mounted on the bracket, thereby facilitating the actual installation and production of the online detection line pressure adjustment device.

[0024] Preferably, the mounting member is mounted on the bracket by bolts, so that the mounting member can be easily installed and removed, thereby facilitating the actual installation of the online detection line pressure regulating device.

[0025] Preferably, the bracket is provided with a mounting member receiving opening, the mounting member being received within the receiving opening, and the first thread pressing plate and the thread pressure detection sensor being located on opposite sides of the mounting member. Accommodating the mounting member within the receiving opening and arranging the first thread pressing plate and the thread pressure detection sensor on opposite sides of the mounting member can, on the one hand, improve structural compactness and reduce the additional space occupied by the online detection and thread pressure adjustment device; on the other hand, it facilitates the layout of the thread pressing surface, the first thread pressing plate, the elastic element, the knob, and other wire structures on the winding machine or embroidery machine.

[0026] Preferably, a sleeve or bearing is rotatably provided on the guide rod, and a thread pressing surface is located between the two ends of the sleeve or bearing. Since the embroidery thread passes between the first thread pressing piece and the thread pressing surface, the embroidery thread is likely to come into contact with the guide rod during operation of the winding machine or embroidery machine. In order to reduce the friction generated by the embroidery thread and the guide rod, the present invention provides a sleeve or bearing on the guide rod, and the thread pressing surface is located between the two ends of the sleeve or bearing. In this way, the sliding friction generated by the embroidery thread and the guide rod is converted into roller friction with the sleeve or bearing (when the embroidery thread and the sleeve or bearing come into contact, the sleeve or bearing rotates), thereby effectively reducing the friction generated by the embroidery thread and the guide rod, and reducing the wear on the embroidery thread.

[0027] Preferably, a display is further included, the display being electrically connected to the line pressure detection sensor to display the pressing force between the first line pressing piece and the line pressing surface detected by the line pressure detection sensor. In this way, in the process of adjusting the pressing force between the first line pressing piece and the line pressing surface by moving the limiting component, the pressing force between the first line pressing piece and the line pressing surface measured by the line pressure detection sensor can be displayed on the display, so that the operator can directly observe the pressing force between the first line pressing piece and the line pressing surface, which is conducive to accurately adjusting the pressing force between the first line pressing piece and the line pressing surface.

[0028] The beneficial effects of the present invention are that it can accurately adjust the pressing force between the first thread pressing piece and the thread pressing surface, ensuring the accuracy and consistency of the adjustment of the embroidery thread tension, thereby improving the quality of textiles. At the same time, it can also effectively avoid the problem of thread breakage caused by excessive pressing force of the thread pressing piece due to poor pressing force adjustment accuracy.

[0047] Specific embodiment 1, as Figures 1-4 As shown, an online detection line pressure adjustment device includes a bracket 1, a guide rod 2, a limiting component 3, a line pressing surface 10 and a first line pressing piece 4, an elastic element 6 and a line pressure detection sensor 8.

[0048] The guide rod 2 is arranged on the bracket 1 .

[0049] In one embodiment, the guide rod 2 is indirectly disposed on the bracket 1 . For example, the guide rod 2 is disposed on the bracket 1 through a mounting member. The guide rod 2 is disposed on the mounting member, and the mounting member is mounted on the bracket 1 .

[0050] In another embodiment, the guide rod 2 is directly disposed on the bracket 1 . For example, the guide rod 2 is directly fixed to the bracket 1 by threads, welding, or bolts.

[0051] The limiting component 3 can move along the guide rod, and the limiting component 3 is connected to the guide rod through a connecting structure. In this embodiment, the limiting component 3 is a knob, and the knob is connected to the guide rod through a threaded connection, and the threaded connection structure between the knob and the guide rod forms the connecting structure.

[0052] Of course, it needs to be said that the purpose is that the limiting component can also be slidably connected to the guide rod. For example, the limiting component is a limiting sleeve, which is slidably connected to the guide rod and locked to the guide rod by a set screw, and the corresponding screw is locked to form the said connection structure; or the limiting component is a clamping hoop, which is clamped on the guide rod, and the corresponding clamping structure of the clamping hoop forms the said connection structure.

[0053] The first pressing piece 4 slides along the guide rod 2. The pressing surface 10, the first pressing piece 4, and the knob are arranged in sequence along the axial direction of the guide rod 2. The elastic element 6 is located between the first pressing piece 4 and the knob (the elastic element abuts between the first pressing piece 4 and the knob), and the first pressing piece 4 is pressed against the pressing surface 10 under the action of the elastic element 6. The elastic element 6 is a spring, an elastic sheet, or an elastic rubber member. In this embodiment, the elastic element 6 is a spring.

[0054] The thread pressure detection sensor 8 is used to detect the pressing force exerted by the elastic element 6 between the first thread pressing piece 4 and the thread pressing surface 10 (i.e., to detect the pressing force exerted on the embroidery thread between the thread pressing piece and the thread pressing surface 10). The thread pressure detection sensor 8 is an existing sensor, such as a force sensor.

[0055] The line pressure detection sensor 8 is provided on the bracket 1 .

[0056] In one embodiment, the line pressure detection sensor 8 is indirectly provided on the bracket 1 . For example, the line pressure detection sensor 8 is provided on the bracket 1 through a mounting member. The line pressure detection sensor 8 is provided on the mounting member. The mounting member is installed on the bracket 1 .

[0057] In another embodiment, the line pressure detection sensor 8 is directly disposed on the bracket 1 . For example, the line pressure detection sensor 8 is directly fixed to the bracket 1 by bolts.

[0058] The embroidery thread passes between the first thread pressing piece 4 and the thread pressing surface 10 , and the embroidery thread is pressed tightly between the first thread pressing piece 4 and the thread pressing surface 10 .

[0059] The specific use of the online detection line pressure adjustment device of this embodiment is as follows:

[0060] The operator adjusts the compression amount of the elastic element 6 by turning the knob, and then adjusts the pressing force between the first thread pressing piece 4 and the thread pressing surface 10. In the process, the operator will detect the pressing force between the first thread pressing piece 4 and the thread pressing surface 10 in real time through the line pressure detection sensor 8. When the line pressure detection sensor 8 measures the pressing force between the first thread pressing piece 4 and the thread pressing surface 10 to reach the set value, the operator stops turning the knob, thereby accurately adjusting the pressing force between the first thread pressing piece 4 and the thread pressing surface 10, ensuring the accuracy and consistency of the embroidery thread tightness adjustment, so as to improve the textile quality. At the same time, it can also effectively avoid the problem of thread breakage caused by poor pressing force adjustment accuracy and excessive pressing force of the thread pressing piece.

[0061] An online thread pressure detection and adjustment device can be used in a sewing machine, an embroidery machine, or a bobbin winder to adjust the tightness of embroidery thread. When the online thread pressure detection and adjustment device of this embodiment is used in a sewing machine, an embroidery machine, or a bobbin winder, the bracket of this embodiment can be formed from a portion of the frame of the sewing machine, embroidery machine, or bobbin winder. Of course, it should be noted that the bracket of this embodiment can also be manufactured independently and then installed on the frame of the sewing machine, embroidery machine, or bobbin winder.

[0062] In one embodiment, Figures 1-4 As shown, the knob is a manual knob. This facilitates the production of the online detection line pressure adjustment device and reduces production costs.

[0063] In another embodiment, Figure 5 As shown, an online detection line pressure adjustment device also includes a drive motor 12. The knob is driven by the drive motor 12. The drive motor 12 is arranged on the bracket 1 to drive the knob to rotate. In this way, the drive motor 12 can be used to drive the knob to rotate to automatically adjust the pressing force between the first thread pressing piece 4 and the thread pressing surface 10. When the line pressure detection sensor 8 measures that the pressing force between the first thread pressing piece 4 and the thread pressing surface 10 reaches a set value, the drive motor 12 stops rotating the knob, thereby automatically and accurately adjusting the pressing force between the first thread pressing piece 4 and the thread pressing surface 10, further ensuring the accuracy and consistency of the embroidery thread tightness adjustment to improve the textile quality. At the same time, it can also reduce labor costs.

[0064] The drive motor 12 is directly set on the bracket 1, for example, the drive motor 12 is directly fixed to the bracket 1 by bolts; or the drive motor 12 is indirectly set on the bracket 1, for example, the drive motor 12 is set on the bracket 1 through a mounting piece, the drive motor 12 is set on the mounting piece, and the mounting piece is installed on the bracket 1.

[0065] In one example, if Figure 5 As shown, the knob is directly fixedly connected to the output shaft of the drive motor 12, and the output shaft of the drive motor 12 is coaxially distributed with the guide rod.

[0066] In another example, the output shaft of the drive motor 12 is connected to the knob via a transmission mechanism (not shown in the figure), and the transmission mechanism is a gear transmission mechanism or a pulley transmission mechanism.

[0067] Further, such as Figure 3 As shown, the first thread pressing piece 4 is provided with an annular protrusion 4.1 that projects toward the thread pressing surface 10, and an annular groove 4.2 is formed on the side facing away from the thread pressing surface 10. The annular protrusion 4.1 is pressed against the thread pressing surface 10 by the elastic element 6. As a result, after passing between the first thread pressing piece 4 and the thread pressing surface 10, the annular protrusion 4.1 presses against the thread pressing surface 10 twice, thereby improving the thread pressing effect.

[0068] In addition, one end of the spring constituting the elastic element 6 is located in the annular groove 4.2, and the one end of the spring is limited by the annular groove 4.2.

[0069] Further, such as Figures 1-4 As shown, an online pressure detection line adjustment device also includes a force transmission element 7. The force transmission element 7 is connected to the online pressure detection sensor 8. The force transmission element 7 is connected to the online pressure detection sensor 8 by bolts, rivets, or welding. In this embodiment, the force transmission element 7 is connected to the online pressure detection sensor 8 by bolts. The force transmission element is a force transmission block.

[0070] In one embodiment, Figure 1 、 Figure 3 、 Figure 4 As shown, an online detection line pressure adjustment device also includes a second wire pressing piece 5. The second wire pressing piece 5 can slide along the guide rod 2. Specifically, the middle part of the first wire pressing piece 4 and the second wire pressing piece 5 are provided with a guide hole, and the guide rod 2 passes through the guide holes in the middle of the first wire pressing piece 4 and the second wire pressing piece 5 in sequence. The side of the second wire pressing piece 5 facing the first wire pressing piece 4 constitutes the wire pressing surface 10. The knob, the first wire pressing piece 4 and the second wire pressing piece 5 are distributed in sequence along the axial direction of the guide rod 2. The second wire pressing piece 5 is pressed against the force transmission element 7 under the action of the elastic element 6. Specifically, the first wire pressing piece 4 and the second wire pressing piece 5 slide along the guide rod 2 under the action of the elastic element 6, and the second wire pressing piece 5 is pressed against the force transmission element 7. In this way, the embroidery thread is pressed tightly by the cooperation of the first wire pressing piece 4 and the second wire pressing piece 5. The first wire pressing piece 4 and the second wire pressing piece 5 can be made separately, which is convenient for improving the smoothness of the wire pressing surface 10 that contacts the embroidery thread. On the other hand, the pressing force exerted by the elastic element 6 between the first wire pressing piece 4 and the wire pressing surface 10 is transmitted to the line pressure detection sensor 8 through the force transmission element 7, which is conducive to adjusting the layout of the line pressure detection sensor 8, the guide rod 2, the wire pressing surface 10 and the first wire pressing piece 4 as needed in actual production.

[0071] The structures of the first pressing piece 4 and the second pressing piece 5 can be the same or different. In this embodiment, the first pressing piece 4 and the second pressing piece 5 have the same structure and are symmetrically distributed.

[0072] In another embodiment, an online detection line pressure adjustment device also includes a second line pressing piece 5. The second line pressing piece 5 is fixed on the force transmission element 7. The middle part of the first line pressing piece 4 and the second line pressing piece 5 is provided with a guide hole, and the guide rod 2 passes through the guide holes in the middle part of the first line pressing piece 4 and the second line pressing piece 5 in sequence. The knob, the first line pressing piece 4 and the second line pressing piece 5 are distributed in sequence along the axial direction of the guide rod 2. The side of the second line pressing piece 5 facing the first line pressing piece 4 constitutes the line pressing surface 10. In this way, the embroidery thread is pressed tightly by the cooperation of the first line pressing piece 4 and the second line pressing piece 5. The first line pressing piece 4 and the second line pressing piece 5 can be made separately, which is convenient for improving the smoothness of the line pressing surface 10 in contact with the embroidery thread. On the other hand, the pressing force of the elastic element 6 acting between the first line pressing piece 4 and the line pressing surface 10 is transmitted to the line pressure detection sensor 8 through the force transmission element 7, which is conducive to adjusting the layout of the line pressure detection sensor 8, the guide rod 2, the line pressing surface 10 and the first line pressing piece 4 as needed in actual production.

[0073] In the third embodiment, the side of the force transmission element 7 facing the first wire pressing plate 4 forms the wire pressing surface 10 (not shown). This eliminates the need for the second wire pressing plate 5, reducing manufacturing costs. Furthermore, the force transmission element 7 transmits the compressive force exerted by the elastic element 6 between the first wire pressing plate 4 and the wire pressing surface 10 to the wire pressure detection sensor 8, facilitating the adjustment of the layout of the wire pressure detection sensor 8, the guide rod 2, the wire pressing surface 10, and the first wire pressing plate 4 as needed during actual production.

[0074] Further, such as Figure 3 As shown, the force transmission element 7 is provided with a guide rod through hole 7.1. The guide rod 2 extends through the guide rod through hole 7.1. The first wire pressing piece 4, the elastic element 6, and the knob are all located on the same side of the guide rod through hole 7.1. This allows the compressive force exerted by the elastic element 6 between the first wire pressing piece 4 and the wire pressing surface 10 to be stably transmitted to the line pressure detection sensor 8 through the force transmission element 7.

[0075] Specific embodiment 2: The rest of the structure of this embodiment refers to specific embodiment 1, except that:

[0076] like Figure 3As shown, a sleeve 11 or bearing is rotatably provided on the guide rod 2, and the sleeve 11 or bearing is coaxially arranged with the guide rod 2. A thread pressing surface 10 is located between the two ends of the sleeve 11 or bearing. The sleeve 11 or bearing passes through the guide hole on the first thread pressing plate 4. Since the embroidery thread passes between the first thread pressing plate 4 and the thread pressing surface 10, the embroidery thread is easily brought into contact with the guide rod 2 during operation of the winding machine or embroidery machine. In order to reduce the friction generated by the contact between the embroidery thread and the guide rod 2, this solution provides a sleeve 11 or bearing on the guide rod 2, and the thread pressing surface 10 is located between the two ends of the sleeve 11 or bearing. In this way, the sliding friction generated by the contact between the embroidery thread and the guide rod 2 is converted into roller friction with the sleeve 11 or bearing (when the embroidery thread contacts the sleeve 11 or bearing, the sleeve 11 or bearing rotates), thereby effectively reducing the friction generated by the contact between the embroidery thread and the guide rod 2 and reducing the wear on the embroidery thread.

[0077] In one embodiment, a shaft shoulder 2.1 and a stop sleeve are provided on the guide rod 2, and the shaft sleeve 11 or the bearing is located between the shaft shoulder 2.1 and the stop sleeve, thereby limiting the position of the shaft sleeve 11 or the bearing.

[0078] In another embodiment, the guide rod 2 is provided with a shaft shoulder 2.1 and a retaining ring, which is clamped on the guide rod 2, and the sleeve 11 or bearing is located between the shaft shoulder 2.1 and the retaining ring, thereby limiting the position of the sleeve 11 or bearing.

[0079] In the third embodiment, a shoulder 2.1 is provided on the guide rod 2, and a sleeve 11 or a bearing is located between the shoulder 2.1 and the bracket 1 or the mounting member where the guide rod 2 is located, thereby limiting the position of the sleeve 11 or the bearing.

[0080] Specific embodiment 3: The rest of the structure of this embodiment refers to specific embodiment 1 or specific embodiment 2, except that:

[0081] An online line pressure detection and adjustment device also includes a display (not shown). The display is electrically connected to the line pressure detection sensor 8 to display the pressing force between the first line pressure plate 4 and the line pressure surface 10 detected by the line pressure detection sensor 8. Thus, when adjusting the pressing force between the first line pressure plate 4 and the line pressure surface 10 by turning the knob, the pressing force between the first line pressure plate 4 and the line pressure surface 10 measured by the line pressure detection sensor 8 can be displayed on the display, making it convenient for operators to directly observe the pressing force between the first line pressure plate 4 and the line pressure surface 10, thereby facilitating accurate adjustment of the pressing force between the first line pressure plate 4 and the line pressure surface 10.

[0082] Of course, it should be noted that an online detection line pressure adjustment device may not be equipped with a display, but may use a signal indicator light to prompt the operator. For example, in the process of adjusting the clamping force between the first wire pressing piece 4 and the wire pressing surface 10 by turning the knob, when the line pressure detection sensor 8 measures that the clamping force between the first wire pressing piece 4 and the wire pressing surface 10 reaches the set value, the signal indicator light will light up or the color of the signal indicator light will turn green to prompt the operator that the line pressure detection sensor 8 measures that the clamping force between the first wire pressing piece 4 and the wire pressing surface 10 reaches the set value, and stop turning the knob.

[0083] In addition, when the knob is driven by the drive motor 12, it is possible to select whether to set a display or a signal indicator light according to actual needs, and it is possible to set a display or a signal indicator light or not. When the line pressure detection sensor 8 measures the pressing force between the first line pressing piece 4 and the line pressing surface 10 to reach a set value, the drive motor 12 is directly controlled to stop rotating the knob.

[0084] Specific embodiment 4: The rest of the structure of this embodiment refers to specific embodiment 1, specific embodiment 2 or specific embodiment 3, except that:

[0085] like Figures 1-4 As shown, in this embodiment, an online detection line pressure adjusting device further includes a mounting member 9. The mounting member 9 is arranged on the bracket 1. The guide rod 2 is arranged on the mounting member 9. The line pressure detection sensor 8 is also arranged on the mounting member 9. The online detection line pressure adjusting device is installed on the bracket 1 through the mounting member 9. In this embodiment, the module of the online detection line pressure adjusting device is centrally installed on the mounting member 9. In this way, during actual production, the module of the online detection line pressure adjusting device can be produced first, and then the mounting member 9 can be installed on the bracket 1, and the online detection line pressure adjusting device can be installed as a whole on the bracket 1 to facilitate the actual installation and production of the online detection line pressure adjusting device.

[0086] Furthermore, the guide rod 2 is fixed to the mounting member 9 by means of threads, welding or bolts. In this embodiment, the mounting member 9 is provided with mounting screw holes, and the guide rod 2 is connected to the mounting screw holes by means of threads.

[0087] Mounting member 9 is bolted to bracket 1. Specifically, mounting member 9 is provided with two mounting ears 9.1, each with a mounting hole. Bolts pass through the mounting holes in the ears to secure mounting member 9 to bracket 1. This facilitates installation and removal of mounting member 9, and thus facilitates the actual installation of the online detection line pressure adjustment device.

[0088] Of course, it should be noted that the mounting member 9 can also be mounted on the bracket 1 by riveting or welding.

[0089] Further, such as Figures 1-4 As shown, the bracket 1 is provided with a mounting member accommodating opening 1.1. The mounting member 9 is accommodated in the mounting member accommodating opening 1.1. The first wire pressing plate 4 and the wire pressure detection sensor 8 are located on opposite sides of the mounting member 9. In this embodiment, the guide rod 2 and the wire pressure detection sensor 8 are also located on opposite sides of the mounting member 9. Accommodating the mounting member 9 in the mounting member accommodating opening 1.1 and arranging the first wire pressing plate 4 and the wire pressure detection sensor 8 on opposite sides of the mounting member 9 can, on the one hand, improve the compactness of the structure and reduce the extra space occupied by the online detection line pressure adjustment device; on the other hand, it is conducive to the layout of the wire pressing surface 10 and the first wire pressing plate 4, the elastic element 6, the knob and other wire structures on the winding machine or embroidery machine.
