Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of embroidery machine accessories, specifically to an automatic thread clamping device structure for embroidery machines that shortens threading time. Background Technology
[0002] In embroidery machines, the thread clamp is used to prevent wind and interference during thread guiding. Each thread needs to pass through a separate windproof flexible tube, such as the thread tube assembly on a computerized embroidery machine disclosed in licensed CN204237992U. This assembly includes a thread frame mounted on the machine frame, a base plate with multiple parallel horizontal bars, and a thread frame tensioning nut assembly on the front horizontal bar. It also includes a thread clamp mounted on the sewing machine head. A thread tube, made of soft plastic, is located between the thread clamp and the thread frame tensioning nut assembly. The thread tube increases the smoothness of thread guiding, protects the stability of the yarn, and completely prevents tangling because the yarn is completely confined within the flexible tube. It also reduces external interference, ensuring smooth thread guiding in that area.
[0003] However, when threading the wire through the flexible conduit, the long length of the conduit and the large number of conduits make the threading process time-consuming and inconvenient. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automatic thread clamping device structure for embroidery machines that shortens threading time, thus solving the problems existing in the prior art.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic thread clamping device structure for embroidery machines that shortens threading time, comprising an automatic thread clamping device body and a thread frame tensioning nut assembly, wherein a thread tube assembly is evenly arranged between the automatic thread clamping device body and the thread frame tensioning nut assembly;
[0006] The conduit assembly includes a conduit and connectors at both ends of the conduit. The top connector is detachably connected to the tension nut assembly of the conduit frame, and the bottom connector is detachably connected to the automatic wire clamp body. Both connectors are equipped with blocking devices. The bottom blocking device is in contact with the mounting ring. The outer diameter of the mounting ring is smaller than the inner diameter of the conduit. A rotating device is provided on the inner wall of the mounting ring, and a wire ring is provided on the rotating device. The rotating device is also equipped with a fixing device for fixing the wire ring.
[0007] Preferably, the inner wall of the loop is provided with arc-shaped transition portions on both sides.
[0008] Preferably, the rotating device includes rotating shafts disposed on both sides of the ring, the rotating shafts being connected to the mounting base via bearings, and the mounting base being disposed within the mounting ring.
[0009] Preferably, the fixing device includes four magnet blocks disposed on the mounting base, and two iron rods are disposed on the rotating shaft, with the two iron rods respectively contacting the two magnet blocks.
[0010] Preferably, the blocking device is a fixing ring disposed inside the joint, the fixing ring being integrally formed with the joint, the bottom of the mounting ring contacting the fixing ring, and the inner diameter of the mounting ring being smaller than the inner diameter of the fixing ring.
[0011] Preferably, guide ropes are evenly arranged circumferentially between the two fixed rings, and the guide ropes pass through the conduit, with the mounting ring slidably sleeved on each guide rope.
[0012] This utility model provides an automatic thread clamping device structure for embroidery machines that shortens threading time. Compared with the prior art, it has the following advantages:
[0013] 1. This automatic thread clamping device for embroidery machines, which shortens threading time, uses a blocking device to allow the thread loop to move within the thread tube to the two joints without falling out. After the thread passes through the thread loop, its gravity causes it to fall freely within the thread tube to the bottom joint, thus shortening the time it takes for the thread to pass through the flexible tube. The thread loop, through a rotating and fixing device, remains stably vertical during threading and horizontal after threading, without affecting the threading of subsequent threads.
[0014] 2. The automatic thread clamping device structure for embroidery machines that shortens threading time, by setting a guide rope to guide the mounting ring, makes the movement of the mounting ring and rotating ring within the thread tube smoother and reduces the possibility of jamming.

[0022] 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.
[0023] See Figures 1-6 This utility model provides the following two technical solutions:
[0024] The first embodiment: an automatic thread clamping device structure for embroidery machines that shortens threading time, including an automatic thread clamping device body 1 and a thread frame tensioning nut assembly 2, with a thread tube assembly evenly arranged between the automatic thread clamping device body 1 and the thread frame tensioning nut assembly 2. All of the above are technologies disclosed in CN204237992U.
[0025] The conduit assembly includes a conduit 4 and connectors 3 at both ends of the conduit 4. The top connector 3 is detachably connected to the tension nut assembly 2 of the wire frame, and the bottom connector 3 is detachably connected to the automatic wire clamp body 1. Both connectors 3 are equipped with blocking devices. The bottom blocking device is in contact with the mounting ring 5. The outer diameter of the mounting ring 5 is smaller than the inner diameter of the conduit 4, allowing the mounting ring 5 to move within the conduit 4. A rotating device is provided on the inner wall of the mounting ring 5, and a wire ring 6 is provided on the rotating device. A fixing device for fixing the wire ring 6 is also provided on the rotating device. The rotating device allows the wire ring 6 to be in a vertical or horizontal state, and the fixing device is used to keep the wire ring 6 in a vertical or horizontal state.
[0026] To prevent the wire from scratching and fraying when moving within the wire ring 6, arc-shaped transition sections 9 are provided on both sides of the inner wall of the wire ring 6.
[0027] The rotating device includes rotating shafts 7 disposed on both sides of the wire ring 6. The rotating shafts 7 are connected to the mounting base 8 through bearings, and the mounting base 8 is disposed inside the mounting ring 5. Rotating the wire ring 6 causes the rotating shafts 7 to rotate on the mounting base 8 through the bearings.
[0028] The fixing device includes four magnet blocks 10 mounted on the mounting base 8. Two iron rods 11 are mounted on the rotating shaft 7. The two iron rods 11 are in contact with the two magnet blocks 10 respectively, so that when the loop 6 rotates, the rotating shaft 7 drives the iron rods 11 to rotate, thus fixing them to the two vertical magnet blocks 10 in the vertical state and to the two horizontal magnet blocks 10 in the horizontal state.
[0029] The blocking device is a fixed ring 12 installed inside the connector 3. The fixed ring 12 is integrally formed with the connector 3. The bottom of the mounting ring 5 contacts the fixed ring 12 to prevent the mounting ring 5 from detaching from the connector 3. The inner diameter of the mounting ring 5 is smaller than the inner diameter of the fixed ring 12, so that the wire ring 6 can rotate inside the fixed ring 12.
[0030] The second implementation method differs from the first implementation method in that: guide ropes 13 are evenly arranged circumferentially between the two fixed rings 12, and the guide ropes 13 pass through the conduit 4. The mounting ring 5 is slidably sleeved on each guide rope 13. The guide ropes 13 guide the mounting ring 5, so that when the mounting ring 5 drives the wire ring 6 through the conduit 4, the smoothness of the movement is improved, and the mounting ring 5 is prevented from tilting and getting stuck.
[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0032] In use, after removing the connectors 3 at both ends, use gravity to move the mounting ring 5 and the wire loop 6 to the top connector 3. At this time, pull the wire on the wire frame tension nut assembly 2 through the vertical wire loop 6, so that the wire is wrapped around the wire loop 6. Then, hold the wire end and the top connector 3 with one hand. The mounting ring 5 will move the wire loop 6 to the bottom fixing ring 12 by gravity. At this time, the wire will also move to the bottom connector 3. Pull the wire at the bottom connector 3 so that the wire end quickly passes through the wire loop 6 and moves out of the bottom connector 3 to complete the wire threading of the conduit 4. After the wire threading is completed, rotate the wire loop 6 to make it horizontal to avoid friction on the subsequent wires. Finally, reinstall the connectors 3 at both ends.
[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
