Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to an electronic thread clamp. Background Technology

[0002] The thread tensioner is a key component of a sewing machine. Its main function is to ensure smooth thread pulling when the sewing machine re-needles, preventing loose threads from remaining on the fabric. Maintaining a balanced tension in the thread tensioner is a crucial technical aspect for ensuring the smooth operation of this function. Different fabric thicknesses often require different thread tension levels.

[0003] With the development of intelligent sewing machines, electronic thread clamps have been applied, and the precision requirements for their control are also increasing. Currently, electronic thread clamps do not know whether the thread is clamped securely or whether the clamping force meets the thread tension requirements. This results in poor stability and accuracy, leading to unsatisfactory sewing results.

[0004] Therefore, there are still shortcomings and deficiencies in the existing technology. How to provide an electronic thread clamp that can adjust the tension of the suture is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] This invention provides an electronic thread tensioner that adjusts the tension of the sewing thread through a pressure sensor 401 and a control system, thereby achieving real-time control of the thread tension and improving the stability and accuracy of the electronic thread tensioner.

[0041] Please refer to this as well. Figures 1 to 9 The electronic wire clamp provided by this utility model includes:

[0042] Casing 1;

[0043] The wire clamping assembly 2 includes a wire clamping base 201 fixed to the housing 1, a wire clamping rod 202 fixed in the wire clamping base 201, a positioning member 203 fixed on the wire clamping rod 202, and a first wire clamping piece 204 and a second wire clamping piece 205 movably sleeved on the wire clamping rod 202. The first wire clamping piece 204 and the second wire clamping piece 205 are distributed between the wire clamping base 201 and the positioning member 203.

[0044] An electromagnet 3 is installed in the housing 1 and is used to push the first wire clamping piece 204 closer to the second wire clamping piece 205 to clamp the sewing thread when energized.

[0045] Pressure detection device 4 is disposed inside housing 1 and includes pressure sensor 401. Pressure sensor 401 is used to detect the pressure between first clamping piece 204 and second clamping piece 205.

[0046] The control system is connected to the pressure sensor 401 and is used to adjust the output thrust of the electromagnet 3 to change the pressure between the first clamping plate 204 and the second clamping plate 205.

[0047] When the above-mentioned electronic thread clamp is used to clamp the thread, the electromagnet 3 is energized to push the first clamping plate 204 to move towards the second clamping plate 205, and the thread is clamped between the first clamping plate 204 and the second clamping plate 205. When the thread is clamped, the pressure sensor 401 collects the actual pressure value Y between the first clamping plate 204 and the second clamping plate 205 in real time, and transmits the actual pressure value Y to the control system. The control system compares and analyzes the preset pressure reference value X and the actual pressure value Y. If the actual pressure value Y is less than the preset pressure reference value X, the control system increases the current through the electromagnet 3 and drives the first clamping piece 204 to move closer to the second clamping piece 205 to increase the pressure between them until the actual pressure value Y collected by the pressure sensor 401 is equal to the preset pressure reference value X. If the actual pressure value Y is greater than the preset pressure reference value X, the control system decreases the current through the electromagnet 3 and drives the first clamping piece 204 away from the second clamping piece 205 to decrease the pressure between them until the actual pressure value Y collected by the pressure sensor 401 is equal to the preset pressure reference value X.

[0048] This setup enables real-time control of wire tension, improving the stability and accuracy of the electronic wire clamp and avoiding the impact of component performance errors, production and installation errors, and transmission errors on the wire tension of the electronic wire clamp.

[0049] It should be noted that the electronic wire clamp provided by this utility model includes a power supply, a current regulator and a signal amplifier. The power supply is provided by the electromagnet 3. The pressure sensor 401 collects information, which is processed by the display amplifier and then outputs a signal to the control system. The control system changes the current through the electromagnet 3 through the current regulator.

[0050] Understandably, the control system can also control the attraction force of electromagnet 3 by controlling the voltage on electromagnet 3, adjusting the pressure between the first clamping plate 204 and the second clamping plate 205, thereby achieving real-time control of wire tension. In this case, the current controller can be replaced with a voltage controller.

[0051] In some embodiments, please refer to the following: Figures 1 to 4 The wire clamping rod 202 is movably provided with a wire loosening pin 5. One end of the wire loosening pin 5 is connected to the first wire clamping piece 204. The electromagnet 3 is connected to the other end of the wire loosening pin 5 through the wire loosening rod 6. The wire loosening rod 6 is located inside the housing 1 and is slidably connected to the housing 1.

[0052] When the electromagnet 3 is energized, it pushes the loosening pin 5 through the loosening rod 6, and then the loosening pin 5 drives the first clamping plate 204 to move to the second clamping plate 205 to clamp the sewing thread.

[0053] In some embodiments, please refer to the following: Figures 1 to 4 The pressure detection device 4 also includes a sensor housing 402, which is movably disposed inside the housing 1. The pressure sensor 401 is installed inside the sensor housing 402. One end of the slack rod 6 is connected to the electromagnet 3, and the other end can contact and abut against the pressure sensor 401. The end of the slack pin 5 away from the first clamping piece 204 is connected to the sensor housing 402.

[0054] When electromagnet 3 is energized and engaged, it pushes the thread release lever 6, which then contacts and abuts against pressure sensor 401. This pressure, through sensor housing 402, pushes thread release pin 5, which in turn pushes the first thread clamping plate 204 towards the second thread clamping plate 205, thus clamping the thread. While the thread is clamped, pressure sensor 401 can collect the actual pressure value between the first and second thread clamping plates 204 and 205 in real time.

[0055] The travel distance of electromagnet 3 and slack rod 6 is greater than the travel distance of the first clamping piece 204, so that pressure sensor 401 can work normally when electromagnet 3 is energized and attracted; when electromagnet 3 is de-energized, slack rod 6 and pressure sensor 401 are not in contact, and the pressure sensor 401 value returns to zero, ensuring the accuracy of pressure detection and control.

[0056] In some embodiments, please refer to the following: Figures 1 to 3A reset spring 601 is fitted on the end of the slack rod 6 away from the sensor. An open retaining ring 602 is also fixed on the slack rod 6. The reset spring 601 is limited between the open retaining ring 602 and the inner wall of the housing 1.

[0057] When the electromagnet 3 is energized, it attracts and pushes the first clamping plate 204 to move towards the second clamping plate 205 to clamp the thread. During this process, as the loosening rod 6 moves, the return spring 601 on the loosening rod 6 is compressed and deformed. When the electromagnet 3 is de-energized, the return spring 601 returns to its original shape and pushes the loosening rod 6 to move.

[0058] In some embodiments, please refer to the following: Figures 6 to 9 The wire clamp 202 includes a fixing part 2021 and two limiting parts 2022 fixed to the end of the fixing part 2021, and a limiting groove 2023 is formed between the two limiting parts 2022.

[0059] Two limiting portions 2022 are located at the same end of the fixing portion 2021, and the two limiting portions 2022 are arranged at intervals relative to each other, thereby forming the aforementioned limiting groove 2023. Specifically, in this embodiment, the cross-section of the limiting portion 2022 is semi-circular.

[0060] The wire clamp 201 is fixed to the housing 1 by a pin, and the wire clamp 202 is fixedly disposed in the center hole inside the wire clamp 201. One end of the fixing part 2021 away from the limiting part 2022 extends out of the wire clamp 201. A nut can be threadedly connected to the end of the fixing part 2021 away from the limiting part 2022, and the nut abuts against the wire clamp 201.

[0061] In some embodiments, please refer to the following: Figure 1 , Figure 2 and Figure 4 The positioning component 203 includes a wire clamp cap 2031 and a pressure plate 2032. The wire clamp cap 2031 and the pressure plate 2032 are fixedly mounted on the wire clamping rod 202. The side of the pressure plate 2032 away from the wire clamp cap 2031 is used to abut against the second wire clamping piece 205.

[0062] When the electromagnet 3 is energized and attracts the first clamping piece 204 to move towards the second clamping piece 205, the pressure plate 2032 remains stationary and presses against the second clamping piece 205, so that the first clamping piece 204 and the second clamping piece 205 clamp the sewing thread.

[0063] In addition, the wire clamp cap 2031 has an inner cavity facing the pressure plate 2032. The inner cavity is provided with a stop pad 2033, which abuts against the pressure plate 2032. By providing the stop pad 2033, the gap between the pressure plate 2032 and the wire clamp cap 2031 is filled, preventing the pressure plate 2032 from moving.

[0064] In some embodiments, please refer to the following: Figures 8 to 9 The wire clamp cap 2031 is fixedly provided with a return component 7, which includes:

[0065] The fixed end 701 abuts against the limiting part 2022 of the clamping rod 202;

[0066] The connecting end 702 is accommodated within the limiting groove 2023 of the clamping rod 202. The end of the connecting end 702 furthest from the fixed end 701 has a receiving groove 7021. A return spring 703 is installed within the receiving groove 7021. One end of the return spring 703 is connected to the inner wall of the receiving groove 7021, and the other end is used to abut against the first clamping piece 204. Specifically, the fixed end 701 is approximately cylindrical, the connecting end 702 is plate-shaped, and the receiving groove 7021 is a U-shaped groove.

[0067] When the electromagnet 3 is energized, it attracts and pushes the first clamping plate 204 towards the second clamping plate 205 to clamp the thread. As the first clamping plate 204 moves, it comes into contact with the return spring 703, causing the return spring 703 to compress and deform. When the electromagnet 3 is de-energized, the return spring 703 returns to its original state and pushes the first clamping plate 204 against the release pin 5, causing the first clamping plate 204 and the second clamping plate 205 to release the thread.

[0068] In some embodiments, please refer to the following: Figures 1 to 3 Electromagnet 3 includes:

[0069] The main body 301 is fixedly mounted on the shell 1;

[0070] The iron core 302 is movably mounted on the main body 301;

[0071] The main shaft 303 is fixedly installed in the iron core 302. One end of the main shaft 303 is fixedly provided with a connector 304. The end of the connector 304 away from the main shaft 303 is connected to the slack rod 6.

[0072] The main body 301 is fixed to the housing 1 by screws, bolts, fixing pins, etc. A bushing 3011 is also fixed on the main body 301, and the main shaft 303 passes through the bushing 3011. The connecting member 304 is a bolt.

[0073] When the electromagnet 3 is energized, the iron core 302 can move along the axis of the main body 301. As the main body 301 moves, the main shaft 303 on the main body 301 moves accordingly, thereby driving the loosening rod 6 to move through the connecting piece 304. The loosening rod 6 contacts and abuts against the pressure sensor 401, pushing the loosening pin 5 through the sensor cover 402. The loosening pin 5 pushes the first clamping plate 204 to move towards the second clamping plate 205, clamping the thread. When the thread is clamped, the pressure sensor 401 can collect the actual pressure value between the first clamping plate 204 and the second clamping plate 205 in real time. When the electromagnet 3 is de-energized, the return spring 601 returns to its original state, pushing the loosening rod 6 to move, and the loosening rod 6 pushes the iron core 302 back to its original position.

[0074] In addition, a rubber pad 3021 is provided on the outside of the iron core 302. The rubber pad 3021 is used to prevent the end of the iron core 302 from directly contacting the main body 301 when the iron core 302 moves. It absorbs impact energy by utilizing the high elastic deformation of rubber, reduces possible impact collisions, and extends service life.

[0075] Optionally, in some embodiments, the spindle 303 is provided with a threaded hole 3031 along the axial direction, one end of the connector 304 is connected to the spindle 303 through the threaded hole 3031, a limit nut 305 is threadedly connected to the connector 304, and a buffer washer 3032 is sleeved and fixed at the end of the spindle 303, with the limit nut 305 abutting against the buffer washer 3032.

[0076] In some embodiments, please refer to the following: Figures 1 to 3 , Figure 5 A connecting rod 2041 is provided at the center hole of the first clamping piece 204. The loosening pin 5 and the return spring 703 are located on both sides of the connecting rod 2041 respectively. One side of the connecting rod 2041 is connected to the end of the loosening pin 5, and the other side can contact and resist the return spring 703.

[0077] When the electromagnet 3 is energized, it attracts the thread, pushing the first thread clamping plate 204 towards the second thread clamping plate 205 via the thread release pin 5 to clamp the thread. As the first thread clamping plate 204 moves, its connecting rod 2041 contacts and abuts against the return spring 703, causing the return spring 703 to compress and deform. When the electromagnet 3 is de-energized, the return spring 703 returns to its original state and, through the connecting rod 2041, pushes the first thread clamping plate 204 against the thread release pin 5, causing the first thread clamping plate 204 and the second thread clamping plate 205 to release the thread.

[0078] In some embodiments, please refer to the following: Figures 1 to 4The wire clamping assembly 2 also includes a wire take-up spring 206, which is housed in the wire clamping seat 201 and sleeved on the wire clamping rod 202. The wire take-up spring 206 has a wire-passing part extending out of the wire clamping seat 201, which is located outside the wire clamping seat 201.

[0079] Please refer to this as well. Figures 1 to 9 The working process of the electronic thread clamp provided by this utility model is as follows: When the electromagnet 3 is energized, the iron core 302 moves along the axis of the main body 301. As the main body 301 moves, the main shaft 303 on the main body 301 moves accordingly, thereby driving the loosening rod 6 to move through the connecting piece 304. The loosening rod 6 contacts and abuts the pressure sensor 401, and pushes the loosening pin 5 through the sensor cover 402. The loosening pin 5 pushes the first clamping piece 204 to move towards the second clamping piece 205, clamping the thread. At this time, the reset spring 601 and the return spring 703 are compressed and deformed. When the electromagnet 3 is de-energized, the reset spring 601 and the return spring 703 return to their original state. The reset spring 601 pushes the loosening rod 6 to move, and the loosening rod 6 pushes the iron core 302 back to its original position. The return spring 703 pushes the first clamping piece 204 and the loosening pin 5 through the connecting rod 2041, so that the first clamping piece 204 and the second clamping piece 205 loosen the thread.

[0080] When the thread is clamped, the pressure sensor 401 collects the actual pressure value Y between the first clamping plate 204 and the second clamping plate 205 in real time and transmits the actual pressure value Y to the control system. The control system compares and analyzes the preset pressure reference value X and the actual pressure value Y. If the actual pressure value Y is less than the preset pressure reference value X, the control system increases the current or voltage through the electromagnet 3 and drives the first clamping plate 204 closer to the second clamping plate 205 to increase the pressure between them until the actual pressure value Y collected by the pressure sensor 401 is equal to the preset pressure reference value X. If the actual pressure value Y is greater than the preset pressure reference value X, the control system decreases the current or voltage through the electromagnet 3 and drives the first clamping plate 204 away from the second clamping plate 205 to reduce the pressure between them until the actual pressure value Y collected by the pressure sensor 401 is equal to the preset pressure reference value X. In this way, the pressure sensor 401 and the control system realize real-time control of the thread tension, improving the stability and accuracy of the electronic thread clamp.
