Description

Technical Field

[0001] This utility model relates to the field of sewing thread processing technology, specifically to a sewing thread production take-up device. Background Technology

[0002] A sewing thread production take-up device is mainly used to take up and neatly store sewing thread during the production process, ensuring the quality and continuity of the thread roll. It plays a vital role in the production line, ensuring that the thread roll does not get tangled, does not break, and is rolled up and unrolled smoothly.

[0003] First, without a stable drive to rotate the winding mechanism, the winding speed will fluctuate, the wire tension will swell, easily causing wire skipping and uneven winding, increasing obstacles in subsequent use.

[0004] Secondly, without the function of quickly repairing or replacing the fixed spool device, repairing or replacing the fixed spool component requires disassembling the machine, which is time-consuming and labor-intensive.

[0005] Finally, without a thread guide to ensure proper thread winding, the thread is prone to localized accumulation or loose winding, resulting in an unstable thread roll structure. Furthermore, the outer layer is tight while the inner layer is loose, leading to knots or slippage during use. Utility Model Content

[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1-5A sewing thread production take-up device includes a main body 1, a drive mechanism, a disassembly mechanism, and a thread control mechanism. The drive mechanism includes a first motor 2 and a rotating component 3. The rotating component 3 is installed inside the main body 1 and rotatably connected to the main body 1. The first motor 2 is fixedly installed at the bottom of the main body 1. A transmission belt 4 is installed on the first motor 2. One end of the transmission belt 4 is connected to the rotating component 3. A roller bearing 5 is provided on the main body 1. The rotating component 3 is installed inside the roller bearing 5. The disassembly mechanism includes a spring 6 and a pressing plate 7. The pressing plate 7 is installed inside the rotating component 3. One end of the spring 6 is fixedly connected to the pressing plate 7. The other end of the spring 6 is provided with a contact plate 8. An mounting part 9 and a cooperating rod 10 are installed on the rotating component 3. The cooperating rod 10 is connected to the rotating component 3 and slidably connected to the contact plate 8. The mounting part 9 is threadedly engaged with the rotating component 3 and rotatably connected to the cooperating rod 10.

[0031] In this embodiment, the driving mechanism includes a first motor 2 and a rotating component 3. In use, the first motor 2 installed at the bottom of the main body 1 drives the driving block 15 to rotate. The transmission belt 4 installed on the driving block 15 rotates and directly drives the rotating component 3 to rotate inside the roller bearing 5 of the main body 1, so that the spool installed on the extrusion plate 7 directly winds the sewing thread to complete the take-up.

[0032] In this embodiment, the disassembly mechanism includes a spring 6 and a compression plate 7. During use, the take-up spring 6 may experience metal fatigue, in which case it can be replaced. Rotate the mounting part 9 installed on the rotating rod 16 to disengage the mounting part 9 from the first threaded hole 17. Then, the mating rod 10 installed in the insertion hole 18 inside the rotating rod 16 is directly pulled out. At this time, the contact plate 8 is no longer under force, and the rubber pad 21 on the compression plate 7 is directly pressed, so that the compression plate 7 can directly compress the spring 6. During this process, the limiting block 20 on the compression plate 7 slides in the limiting groove 19. After the compression plate 7 and the spring 6 are completely compressed, the compression plate 7 is pulled out as a whole for repair or replacement. Then, it can be installed back on the rotating rod 16 in the above manner. When it is necessary to put on the spool, press the rubber pad 21 directly to make the compression rod retract into the rotating tube, and then put on the spool.

[0033] In this embodiment, the thread control mechanism includes a second motor 11 and a lead screw 12. In use, one end of the thread is passed through the bottom of the tension rod 14 of the upright plate 24 and through the thread hole 23 of the actuating rod 13, and then fixed on the spool. At this time, the rotation of the rotating part 3 causes the spool to start winding the thread. Then the second motor 11 drives the lead screw 12 to rotate on the upright plate 24, and the actuating rod 13 slides left and right on the lead screw 12 under the action of the second threaded hole 22, completing the actuation of the sewing thread, making the thread on the spool neater.

[0034] Example 2:

[0035] In summary, during use, the extrusion plate 7 can be repaired or replaced based on the elasticity changes of spring 6. The take-up spring 6 may experience metal fatigue and can be replaced. Rotate the mounting part 9 installed on the rotating rod 16 to disengage it from the first threaded hole 17. Then, the mating rod 10 installed in the insertion hole 18 inside the rotating rod 16 can be directly pulled out. At this point, the contact plate 8 is no longer under force, and the rubber pad 21 on the extrusion plate 7 can be directly pressed, allowing the extrusion plate 7 to directly compress the spring 6. During this process, the limiting block 20 on the extrusion plate 7 slides in the limiting groove 19. After the extrusion plate 7 and spring 6 are completely compressed, the extrusion plate 7 can be pulled out for repair or replacement. It can then be reinstalled on the rotating rod 16 in the same manner. When a spool needs to be fitted, the rubber pad 21 can be pressed directly. The extrusion rod retracts into the rotating tube and then the spool is fitted onto it. The first motor 2 then drives the drive block 15 to rotate. The transmission belt 4 mounted on the drive block 15 rotates, which in turn drives the rotating component 3 to rotate inside the roller bearing 5 of the main body 1. This causes the spool mounted on the extrusion plate 7 to directly wind the sewing thread, completing the take-up. Before the thread is wound onto the spool, one end of the thread is passed through the bottom of the tension rod 14 on the upright plate 24 and through the thread hole 23 of the actuating rod 13, and then fixed onto the spool. At this time, the rotation of the rotating component 3 causes the spool to begin winding the thread. The second motor 11 then drives the lead screw 12 to rotate on the upright plate 24. The actuating rod 13 slides left and right on the lead screw 12 under the action of the second threaded hole 22, completing the actuation of the sewing thread and making the thread on the spool neater.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
