Description

Technical Field

[0001] This utility model relates to the field of automatic sewing thread winding technology, specifically a sewing thread production winding device. Background Technology

[0002] Sewing thread is the thread required for knitted garments. Sewing thread can be divided into three main categories according to its raw materials: natural fiber sewing thread, synthetic fiber sewing thread, and blended sewing thread. Sewing thread needs to be rolled up during processing and transportation.

[0003] According to a sewing thread production take-up device disclosed in the above application (Announcement No.: CN222312348U), when the sewing thread is taut, the first tension spring will not contract. When the sewing thread is too loose, the first tension spring will drive the first support plate, the first mounting rod, and the first pulley to contract, so that the sewing thread is always taut. When the sewing thread is too loose at the lower tension adjustment device position, the second tension spring will rebound, reducing the distance between the second support plate and the second fixed plate.

[0004] However, in actual use, the tension adjustment device uses a contraction spring to keep the guide roller in contact with the curved surface of the sewing thread. During take-up, the instability of the contraction spring causes the guide roller to vibrate. Consequently, the sewing thread is prone to breakage during take-up. Therefore, we propose a sewing thread production take-up device. Utility Model Content

[0005] The purpose of this invention is to provide a sewing thread production take-up device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewing thread production take-up device, comprising a mounting plate, a take-up assembly disposed on the upper surface of the mounting plate, a guide cylinder rotatably connected to the upper surface of the mounting plate via a connecting frame, a mounting bracket fixedly mounted on the upper surface of the mounting plate, a drive motor fixedly mounted on the side wall of the mounting bracket, a threaded rod fixedly mounted on the output end of the drive motor, a guide block being drivenly connected to the arc surface of the threaded rod, a guide mechanism disposed inside the guide block, and an auxiliary mechanism disposed inside the guide block, the guide mechanism comprising: A straight rod is fixedly installed on the inner wall of the guide block. A torsion spring is fixedly connected to the arc surface of the straight rod.

[0007] Preferably, the auxiliary mechanism includes a friction protrusion, which is fixedly installed on the side of the fixing button near the guide block, and a rubber strip is fixedly installed on the side wall of the guide block.

[0008] Preferably, the side wall of the guide block is provided with an arc-shaped groove, and rubber strips are fixedly installed on both sides of the opening of the arc-shaped groove. The rubber strips increase the contact area with the fixing button and ensure the stability of the fixing button.

[0009] Preferably, the side wall of the swing frame is provided with a circular groove, and the swing frame is sleeved on the arc surface of the straight rod, so that the swing frame can rotate on the arc surface of the straight rod.

[0010] Preferably, the arc surface of the limiting cylinder is fitted to the inner wall of the arc groove, so that the limiting cylinder can slide along the inside of the arc groove.

[0011] Preferably, there are two fixing buttons, which are arranged in a mirror image on both sides of the guide block for easy access from both sides.

[0013] Compared with the prior art, this utility model provides a sewing thread production take-up device, which has the following beneficial effects: 1. This sewing thread production take-up device, through the setting of a guide mechanism, fixes the surface of the sewing thread-fitting roller to the arc surface of the take-up assembly. The torsion spring causes the roller on the swing frame to fit against the arc surface of the sewing thread, and the tension is adjusted to ensure that the sewing thread is stably taken up. At the same time, the adjustable fixing button can be threadedly connected to the inside of the limiting cylinder, so that the fixing button fits against the side wall of the guide block and squeezes and fixes the swing frame, so that the sewing thread is stably taken up and the possibility of breakage is reduced.

[0014] 2. This sewing thread production take-up device is equipped with an auxiliary mechanism. Rubber strips are fixedly installed on both sides of the arc-shaped groove opening. The rubber strips increase the contact area with the friction protrusions on the fixing button, ensuring the stability of the fixing button, promoting stable take-up of the sewing thread, and reducing the possibility of breakage.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a sewing thread production take-up device, including a mounting plate 1, a take-up assembly 2 provided on the upper surface of the mounting plate 1, a guide cylinder 5 rotatably connected to the upper surface of the mounting plate 1 via a connecting frame, a mounting frame 6 fixedly mounted on the upper surface of the mounting plate 1, a drive motor 7 fixedly mounted on the side wall of the mounting frame 6, a threaded rod 8 fixedly mounted on the output end of the drive motor 7, a guide block 9 being connected to the arc surface of the threaded rod 8, a guide mechanism 3 being provided inside the guide block 9, and an auxiliary mechanism 4 being provided inside the guide block 9. The guide mechanism 3 includes a straight rod 301, a torsion spring 302, a swing frame 303, a circular roller 304, a protective roller 305, a limiting cylinder 306, and a fixing button 307.

[0018] In one embodiment of this utility model, a straight rod 301 is fixedly installed on the inner wall of the guide block 9. A torsion spring 302 is fixedly connected to the arc surface of the straight rod 301. The end of the torsion spring 302 away from the arc surface of the straight rod 301 is fixedly connected to the inner wall of the swing frame 303. A circular roller 304 is rotatably connected to the side wall of the swing frame 303. A protective roller 305 is rotatably connected to the inner wall of the guide block 9. A limiting cylinder 306 is fixedly installed on the side wall of the swing frame 303. A fixing button 307 is threadedly connected to the inner wall of the limiting cylinder 306.

[0019] In addition, the auxiliary mechanism 4 includes a friction protrusion 401, which is fixedly installed on the side of the fixing button 307 near the guide block 9. A rubber strip 402 is fixedly installed on the side wall of the guide block 9. An arc-shaped groove is opened on the side wall of the guide block 9, and rubber strips 402 are fixedly installed on both sides of the arc-shaped groove opening. The rubber strips 402 increase the contact area with the fixing button 307 and ensure the stability of the fixing button 307.

[0020] In this embodiment of the invention, the side wall of the swing frame 303 is provided with a circular groove. The swing frame 303 is fitted onto the arc surface of the straight rod 301, allowing the swing frame 303 to rotate on the arc surface of the straight rod 301. The arc surface of the limiting cylinder 306 fits against the inner wall of the arc groove, allowing the limiting cylinder 306 to slide along the inside of the arc groove. Two fixing buttons 307 are provided, and the two fixing buttons 307 are mirror-distributed on both sides of the guide block 9 for easy adjustment from both sides. The surface of the limiting cylinder 306 is provided with a threaded groove, so that the fixing button 307 can be threadedly connected to the inside of the limiting cylinder 306, and the fixing button 307 is pressed against the side wall of the guide block 9 to fix the swing frame 303. The protective roller 305 protects the upper arc surface of the sewing thread. The take-up assembly 2 includes a take-up frame fixedly installed on the mounting plate 1. A rotary motor is fixedly installed on the side wall of the take-up frame. A take-up roller is fixedly installed at the output end of the rotary motor.
