Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and in particular to a thread clamp for detecting broken threads in embroidery machines. Background Technology

[0002] When a thread breaks in an embroidery machine, it will affect the machine's operation. Therefore, a thread breakage detection device is needed to detect the location of the breakage and ensure the normal operation of the embroidery machine. In order to detect thread breakage in a timely manner, existing technologies use a thread breakage spring to detect the condition of the thread, or use multiple slotted optocouplers on a circuit board to cooperate with grating wheels on their respective lines to detect the state of the thread on each line.

[0003] However, when using a break spring to detect the condition of the thread, the steel wire spring is prone to deformation, and the installation environment is very confined, resulting in a very small swing amplitude. Furthermore, the detection relies on its own gravity, which often leads to false detections or no detections, thus affecting the reliability and stability of the embroidery machine's thread breakage detection. Using a slotted optical coupler in conjunction with a grating wheel for thread breakage detection requires the thread to drive the grating wheel, and the friction between the thread and the grating wheel also affects the tension stability of the thread during its movement, thus impacting the quality of the embroidery.

[0004] Chinese patent CN201020605560.7, published on 2011-07-06, discloses a thread breakage detection device for a chain embroidery machine. During thread weaving, the thread passes through a rotating wheel, and the friction between the thread and the wheel drives its rotation. The rotating wheel is coaxially connected to a subsequent grating wheel, and an optocoupler on the grating wheel detects whether it is rotating. When a thread breaks, both the rotating wheel and the grating wheel stop rotating. Upon detection by the optocoupler, a signal is immediately sent to the machine's computer control center, which then issues an alarm and initiates a stop operation. The main drawbacks of this thread breakage detection device are: the friction between the thread and the rotating wheel causes changes in thread tension, affecting the quality of the embroidery; and the structure is complex, has high production costs, and is difficult and troublesome to maintain. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the prior art by providing a thread breakage detection clamp for embroidery machines. This clamp can ensure the reliability and stability of thread breakage detection in embroidery machines, as well as the tension stability of the thread during weaving, thereby ensuring the quality of the embroidery.

[0006] This utility model proposes a thread breakage detection clamp for an embroidery machine, including a clamp body and a Hall sensor component disposed on the clamp body. The clamp body is provided with a first thread passage hole, and the Hall sensor component is provided with a second thread passage hole. The embroidery thread passes through the first thread passage hole and the second thread passage hole in sequence. The Hall sensor component is used to detect thread breakage.

[0007] Furthermore, the bottom of the wire clamp body is provided with a wire guide baffle, the first wire guide hole is provided on the wire guide baffle, and the Hall sensor component is provided on the top of the wire clamp body.

[0008] Furthermore, the wire clamp also includes a thread tension adjuster disposed in the middle of the wire clamp body, the thread tension adjuster being used to adjust the tension of the thread that passes through the first thread hole and the second thread hole in sequence.

[0009] Furthermore, the Hall sensor assembly includes a Hall sensor bracket and a Hall sensor mounting base. The Hall sensor mounting base is fixedly connected to the main body of the wire clamp. One end of the Hall sensor bracket is rotatably connected to the Hall sensor mounting base, and the other end extends away from the Hall sensor mounting base.

[0010] Furthermore, the Hall sensor mounting base has a quick-release mounting buckle on its back, and the cable clamp body has a quick-release mounting hole, with the quick-release mounting buckle engaging with the quick-release mounting hole.

[0011] Furthermore, the Hall sensor bracket has a first wire-passing block at one end extending away from the Hall sensor mounting base, and the Hall sensor mounting base has a second wire-passing block, with the second wire-passing hole formed on the first wire-passing block and the second wire-passing block.

[0012] Furthermore, the second through hole formed on the first threading block and the second threading block is a semi-open structure.

[0013] Furthermore, the Hall sensor assembly also includes a Hall bottom detection strip disposed on the back of the wire clamp body. The quick-release mounting hole penetrates the wire clamp body and the Hall bottom detection strip. A sensing block is disposed on the Hall bottom detection strip. A sensing magnet is disposed on the back of the Hall sensor bracket. When the yarn is working normally, the sensing magnet is within the sensing range of the sensing block. When the yarn breaks, the sensing magnet is outside the sensing range of the sensing block.

[0014] Furthermore, the Hall sensor bracket has an upper stop protrusion at the top and a lower stop protrusion at the bottom. When the yarn is working normally, the upper stop protrusion abuts against the main body of the yarn clamp under the tension of the yarn. When the yarn breaks, the lower stop protrusion abuts against the main body of the yarn clamp under the gravity of the Hall sensor bracket itself.

[0015] Furthermore, the Hall sensor mounting base is provided with a fixing pin hole, the Hall sensor bracket is provided with a rotating pin hole, and the Hall sensor assembly also includes a rotating shaft passing through the fixing pin hole and the rotating pin hole.

[0016] The thread clamp for detecting thread breakage on an embroidery machine proposed in this utility model has the following beneficial effects:

[0017] (1) After the thread of the embroidery machine passes through the second thread hole on the Hall sensor component, the thread clamp detects the change in magnetic field caused by the change in its position through the Hall sensor component to detect the thread breakage. This will not cause false detection or failure to detect, thus ensuring the reliability and stability of the thread breakage detection of the embroidery machine, and can also ensure the tension stability of the thread when it travels, thus ensuring the quality of the embroidery.

[0018] (2) The thread guide baffle, the thread tension regulator and the Hall sensor are arranged in order from top to bottom under the main body of the thread clamp. Therefore, when the thread of the embroidery machine passes through the first thread hole and the second thread hole from bottom to top, the tension of the thread is adjusted by the thread tension regulator located between the first thread hole and the second thread hole, so as to ensure the embroidery effect of the embroidery machine and thus ensure the quality of the embroidery.

[0019] (3) The Hall sensor component of this wire clamp includes a Hall sensor bracket and a Hall sensor mounting base. The Hall sensor mounting base is fixedly connected to the main body of the wire clamp. One end of the Hall sensor bracket is rotatably connected to the Hall sensor mounting base, and the other end extends away from the Hall sensor mounting base. Thus, the change in magnetic field caused by the change in position of the Hall sensor bracket is detected by the Hall sensor component, and the wire breakage is detected.

[0020] (4) The Hall sensor mounting base of this wire clamp is provided with a quick-release mounting buckle on the back and a quick-release mounting hole is provided on the main body of the wire clamp. By the quick-release mounting buckle and the quick-release mounting hole, the Hall sensor mounting base can be fixedly installed on the main body of the wire clamp. This makes it easy and convenient to install and remove the Hall sensor mounting base on the main body of the wire clamp, which facilitates the maintenance and replacement of the Hall sensor component and makes the wire breakage detection wire clamp more practical.

[0021] (5) The second thread-passing hole formed on the first thread-passing block and the second thread-passing block of this thread clamp is a semi-open structure, that is, an opening is provided on the first thread-passing block and the second thread-passing block. The opening connects the second thread-passing hole on the first thread-passing block and the second thread-passing block with the outside world, so that the weaving thread of the embroidery machine can pass through the opening on the first thread-passing block and the second thread-passing block and pass through the second thread-passing hole on the first thread-passing block and the second thread-passing block, thereby making the thread-passing operation simpler, more convenient and easier to implement, and thus making the use of this thread breakage detection thread clamp more convenient and faster.

[0022] (6) The Hall sensing component of this wire clamp also includes a Hall bottom detection strip. The Hall bottom detection strip is set on the back of the wire clamp body. A sensing block is provided on the Hall bottom detection strip. A sensing magnet is provided on the back of the Hall sensing bracket. When the yarn is working normally, the sensing magnet is within the sensing range of the sensing block. When the yarn breaks, the Hall sensing bracket rotates on the Hall sensing mounting base, causing the position of the sensing magnet to change, so that the sensing magnet exceeds the sensing range of the sensing block. Thus, the magnetic field change is detected by the sensing block, and the yarn breakage detection is realized.

[0023] (7) The quick-release mounting hole of this wire clamp passes through the wire clamp body and the Hall bottom inspection strip. Therefore, through the quick-release mounting buckle on the back of the Hall sensor mounting base, it passes through the quick-release mounting hole on the wire clamp body and the Hall bottom inspection strip in sequence, and then engages with the Hall bottom inspection strip, or engages with and disengages from the Hall bottom inspection strip, thereby realizing the installation and removal of the Hall sensor component on the wire clamp body, further facilitating the maintenance and replacement of the Hall sensor component, and making the wire breakage detection wire clamp more practical.

[0024] (8) The Hall sensor bracket of this wire clamp is provided with an upper stop boss at the top and a lower stop boss at the bottom. When the upper stop boss abuts against the main body of the wire clamp, the sensing magnet is within the sensing range of the sensing block. When the lower stop boss abuts against the main body of the wire clamp, the sensing magnet is outside the sensing range of the sensing block. Thus, the magnetic field change is detected by the sensing block, and the wire breakage detection is realized. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] Please see Figures 1-6 A thread breakage detection device for an embroidery machine according to an embodiment of the present invention includes a thread clamp body 1 and a Hall sensor component 2 disposed on the thread clamp body 1. The thread clamp body 1 is provided with a first thread passage hole 111, and the Hall sensor component 2 is provided with a second thread passage hole 21. The weaving thread passes through the first thread passage hole 111 and the second thread passage hole 21 in sequence. The Hall sensor component 2 is used to detect thread breakage.

[0035] In this application, the thread breakage detection clamp for an embroidery machine includes a clamp body 1 and a Hall effect sensor 2. The clamp body 1 has a first thread passage hole 111, and the Hall effect sensor 2 has a second thread passage hole 21. The embroidery machine thread passes through the first thread passage hole 111 and the second thread passage hole 21 sequentially. The Hall effect sensor 2 detects thread breakage, thereby promptly identifying thread breaks and ensuring the quality of the embroidery.

[0036] Since the Hall effect sensor 2 works on the principle of Hall effect to detect magnetic fields and their changes, after the embroidery thread passes through the second thread hole 21 on the Hall effect sensor 2, the Hall effect sensor 2 detects the change in magnetic field caused by the change in its position, and performs thread breakage detection. This will not cause false detection or failure to detect, thus ensuring the reliability and stability of thread breakage detection in the embroidery machine, and also ensuring the tension stability of the thread during its movement, thereby ensuring the quality of the embroidery.

[0037] In this embodiment, the Hall sensor component 2 is disposed on the top of the thread clamp body 1, and the bottom of the thread clamp body 1 is provided with a thread guide baffle 11. The first thread guide hole 111 is disposed on the thread guide baffle 11, and the second thread guide hole 21 is disposed on the Hall sensor component 2, so that the embroidery thread of the embroidery machine passes through the first thread guide hole 111 and the second thread guide hole 21 from bottom to top. Then, the Hall sensor component 2 detects the thread breakage and promptly detects the breakage of the thread to ensure the embroidery effect of the embroidery machine.

[0038] In this embodiment, the thread clamp also includes a thread tension adjuster 3 disposed in the middle of the thread clamp body 1. The thread tension adjuster 3 is used to adjust the tension of the thread that passes through the first thread hole 111 and the second thread hole 21 in sequence. In this application, the embroidery machine thread breakage detection thread clamp also includes a thread tension adjuster 3, which is disposed in the middle of the thread clamp body 1.

[0039] Since the Hall sensor component 2 is located at the top of the thread clamp body 1, the thread tension regulator 3 is located in the middle of the thread clamp body 1, and the thread guide baffle 11 is located at the bottom of the thread clamp body 1, that is, the thread guide baffle 11, the thread tension regulator 3, and the Hall sensor component 2 are arranged sequentially from bottom to top on the thread clamp body 1, when the thread of the embroidery machine passes through the first thread guide hole 111 and the second thread guide hole 21 sequentially from bottom to top, the tension of the thread is adjusted by the thread tension regulator 3 located between the first thread guide hole 111 and the second thread guide hole 21, thereby ensuring the embroidery effect of the embroidery machine and thus ensuring the quality of the embroidery.

[0040] Specifically, the specific structure of the yarn tension regulator 3 in this application can be found in Chinese utility model patent with publication number CN219342533U and patent name "A Yarn Tension Regulator, Yarn Clamping Device and Embroidery Machine".

[0041] In this embodiment, the Hall sensor assembly 2 includes a Hall sensor bracket 22 and a Hall sensor mounting base 23. The Hall sensor mounting base 23 is fixedly connected to the wire clamp body 1. One end of the Hall sensor bracket 22 is rotatably connected to the Hall sensor mounting base 23, and the other end extends away from the Hall sensor mounting base 23.

[0042] After the embroidery thread passes through the second thread guide hole 21, the Hall sensor component 2 detects the change in magnetic field caused by the change in position of the Hall sensor bracket 22 to detect thread breakage. This ensures the reliability and stability of the embroidery machine's thread breakage detection, without false detections or failures to detect, and also ensures the tension stability of the thread during its movement, thus guaranteeing the quality of the embroidery.

[0043] Specifically, in this embodiment, the back of the Hall sensor mounting base 23 is provided with a quick-release mounting buckle 231, and the main body 1 of the wire clamp is provided with a quick-release mounting hole 12. By the insertion and cooperation of the quick-release mounting buckle 231 and the quick-release mounting hole 12, the Hall sensor mounting base 23 is fixedly installed on the main body 1 of the wire clamp. This makes the installation and removal of the Hall sensor mounting base 23 on the main body 1 simple, convenient and easy to implement, thereby facilitating the maintenance and replacement of the Hall sensor component 2 and making the wire breakage detection wire clamp more practical.

[0044] In this embodiment, the Hall sensor bracket 22 is provided with a first wire guide block 221 at one end extending away from the Hall sensor mounting base 23, and the Hall sensor mounting base 23 is provided with a second wire guide block 232. The second wire hole 21 is formed on the first wire guide block 221 and the second wire guide block 232.

[0045] The embroidery machine's thread passes through the second thread hole 21 on the first threading block 221 and the second threading block 232 from bottom to top. By detecting the change in magnetic field caused by the change in the position of the Hall sensor bracket 22, the thread breakage is detected. This avoids false detections and failures to detect, thus ensuring the reliability and stability of the embroidery machine's thread breakage detection. It also ensures the tension stability of the thread during its movement, thereby guaranteeing the quality of the embroidery.

[0046] In this embodiment, the second thread-passing hole 21 formed on the first thread-passing block 221 and the second thread-passing block 232 is a semi-open structure, that is, the first thread-passing block 221 and the second thread-passing block 232 are provided with openings, which connect the second thread-passing hole 21 on the first thread-passing block 221 and the second thread-passing block 232 to the outside, so that the thread of the embroidery machine can pass through the openings on the first thread-passing block 221 and the second thread-passing block 232 and pass through the second thread-passing hole 21 on the first thread-passing block 221 and the second thread-passing block 232, thereby making the thread-passing operation simpler, more convenient and easier to implement, and thus making the use of this thread breakage detection clamp more convenient and faster.

[0047] Specifically, in actual implementation, the openings on the first threading block 221 and the second threading block 232 can be set on one side of the first threading block 221 and the second threading block 232, so that the first threading block 221 and the second threading block 232 form a hook-shaped structure. This ensures that the second thread hole 21 is a semi-open structure, which facilitates the threading of the yarn, and also allows the second thread hole 21 on the first threading block 221 and the second threading block 232 to play a better limiting role for the yarn, preventing the yarn from passing through the second thread hole 21 when it breaks, reducing subsequent threading operations, and thus making the use of this yarn breakage detection clamp simpler and more efficient.

[0048] In this embodiment, the Hall sensing component 2 further includes a Hall bottom detection strip 24, which is disposed on the back of the wire clamp body 1. A sensing block 241 is provided on the Hall bottom detection strip 24, and a sensing magnet 222 is provided on the back of the Hall sensing bracket 22.

[0049] When the yarn is working normally, the sensing magnet 222 is within the effective sensing range of the sensing block 241. However, when the yarn breaks, the Hall sensor bracket 22 rotates on the Hall sensor mounting base 23, causing the position of the sensing magnet 222 to change, thus moving the sensing magnet 222 beyond the effective sensing range of the sensing block 241. This allows the sensing block 241 to detect changes in the magnetic field, thereby achieving yarn breakage detection. It is foreseeable that in this application, the sensing block 241 is a Hall element capable of detecting magnetic fields and their changes.

[0050] The quick-release mounting hole 12 passes through the clamp body 1 and the Hall bottom inspection strip 24. Therefore, the quick-release mounting buckle 231 on the back of the Hall sensor mounting base 23 passes through the quick-release mounting hole 12 on the clamp body 1 and the Hall bottom inspection strip 24 in sequence, and then fastens with the Hall bottom inspection strip 24. This fixes the Hall sensor mounting base 23 on the front of the clamp body 1 and fixes the Hall bottom inspection strip 24 on the back of the clamp body 1, thus realizing the installation of the Hall sensor component 2 on the clamp body 1.

[0051] Furthermore, once the quick-release mounting buckle 231 is disengaged from the Hall bottom inspection strip 24, the quick-release mounting buckle 231 can be pulled out sequentially from the Hall bottom inspection strip 24 and the quick-release mounting hole 12 on the clamp body 1, thereby simultaneously removing the Hall sensor mounting base 23 and the Hall bottom inspection strip 24 from the clamp body 1, further facilitating the maintenance and replacement of the Hall sensor component 2, and making the practicality of this wire breakage detection clamp stronger.

[0052] In practical implementation, the quick-release mounting buckle 231 of this application can be made of a plastic material with a certain elastic deformation capability, and a hook extending vertically outward is provided at the end of the quick-release mounting buckle 231 away from the Hall sensor bracket 22. At least two quick-release mounting buckles 231 are provided on the Hall sensor mounting base 23, and at least two quick-release mounting holes 12 are correspondingly provided.

[0053] When installing the Hall sensor component 2 on the wire clamp body 1, first apply force to the two quick-release mounting buckles 231 on the Hall sensor mounting base 23 to make them elastically deform and move closer to each other until the two quick-release mounting buckles 231 can pass through the two quick-release mounting holes 12 on the wire clamp body 1 and the Hall bottom inspection strip 24 respectively.

[0054] Then the force applied to the two quick-release mounting buckles 231 is removed, allowing them to return to their original state under the action of restoring their own elastic deformation, so that the hooks at the ends of the two quick-release mounting buckles 231 are fastened to the back of the Hall bottom inspection strip 24, thus completing the installation of the Hall sensing component 2 on the clamp body 1.

[0055] When removing the Hall sensor assembly 2 from the wire clamp body 1, first apply force to the two quick-release mounting buckles 231 on the Hall sensor mounting base 23 to cause them to elastically deform and move closer to each other until the hooks at the ends of the two quick-release mounting buckles 231 disengage from the fastening on the back of the Hall bottom inspection strip 24. At this time, the hooks at the ends of the two quick-release mounting buckles 231 can pass through the two quick-release mounting holes 12 on the wire clamp body 1 and the Hall bottom inspection strip 24, respectively.

[0056] Then, the two quick-release mounting buckles 231 are pulled out from the two quick-release mounting holes 12 on the wire clamp body 1 and the Hall bottom inspection strip 24, respectively. Finally, the force applied to the two quick-release mounting buckles 231 is removed, so that they return to their original state under the action of restoring their own elastic deformation, thereby completing the disassembly of the Hall sensing component 2 on the wire clamp body 1.

[0057] Specifically, in this embodiment, the Hall sensor bracket 22 has an upper stop protrusion 223 at the top and a lower stop protrusion 224 at the bottom. When the yarn is working normally, the yarn abuts against the inner wall of the second thread hole 21 on the Hall sensor bracket 22, thereby causing the upper stop protrusion 223 to abut against the wire clamp body 1 under the tension of the yarn. At this time, the sensing magnet 222 on the back of the Hall sensor bracket 22 is within the effective sensing range of the sensing block 241.

[0058] When the thread breaks, it no longer abuts against the inner wall of the second thread hole 21 on the Hall sensor bracket 22, losing the tension of the thread. Under its own weight, the Hall sensor bracket 22 rotates around the end rotatably connected to the Hall sensor mounting base 23, causing the sensing magnet 222 to rotate synchronously until the lower stop boss 224 abuts against the thread clamp body 1. At this time, the sensing magnet 222 exceeds the effective sensing range of the sensing block 241, thereby detecting the change in magnetic field through the sensing block 241 to realize the thread breakage detection. This ensures the reliability and stability of the thread breakage detection of the embroidery machine, without false detection or failure to detect, and also ensures the tension stability of the thread during its movement, thus guaranteeing the quality of the embroidery.

[0059] Specifically, in this embodiment, the Hall sensor mounting base 23 is provided with a fixing pin hole 233, and the Hall sensor bracket 22 is provided with a rotating pin hole 225. The Hall sensor assembly 2 also includes a rotating shaft 25, which passes through both the fixing pin hole 233 and the rotating pin hole 225, thereby rotatably connecting one end of the Hall sensor bracket 22 to the Hall sensor mounting base 23.

[0060] When the yarn breaks, the Hall sensor bracket 22 rotates around the rotating shaft 25 under its own gravity, driving the sensing magnet 222 to rotate synchronously until the lower stop boss 224 abuts against the main body 1 of the yarn clamp, causing the sensing magnet 222 to exceed the effective sensing range of the sensing block 241. Thus, the sensing block 241 detects the change in magnetic field and realizes the yarn breakage detection.

[0061] The above-described contents can be implemented individually or in combination in various ways, and all such variations are within the protection scope of this utility model.
