Description

Technical Field

[0001] The utility model relates to the technical field of sewing thread management, in particular to a sewing thread management device. Background Art

[0002] In the sewing industry, the arrangement and storage of sewing threads are key links to ensure production efficiency and product quality. With the continuous expansion of production scale and the increasing requirements for sewing precision;

[0003] A search revealed a Chinese patent with publication number CN209758702U, which provides a thread-managing device for sewing threads. The device passes the remaining scattered sewing threads through the gap between the open rollers one and two, then rotates the rocker to drive the bevel gear two, causing the bevel gear one to drive the winding drum on the rotating drum to rotate. The scattered sewing threads are then wound around the winding drum in the winding drum rotation mode, eliminating the need for manual winding and arranging, thereby improving thread-managing efficiency.

[0020] By means of the above technical solution, the present invention provides a thread management device for sewing threads, which has at least the following beneficial effects:

[0021] 1. The thread-managing device for sewing threads rotates through the reciprocating screw. Since the moving block is threadedly connected to the reciprocating screw through the threaded hole and is slidably connected thereto, the moving block will make reciprocating linear motion on the reciprocating screw, and the guide ring on its top surface will also move accordingly, guiding the sewing thread to move back and forth in the axial direction of the winding shaft, ensuring that the sewing thread is evenly wound on the winding shaft, realizing automatic winding and arranging of the sewing thread, avoiding problems such as sewing thread knotting or poor extraction caused by uneven winding, and improving the winding quality.

[0022] 2. This thread-managing device for sewing threads uses a tension spring to allow the slider to slide along the guide rail, so that the circular pressure block applies stable pressure to the winding drum, ensuring that the winding drum will not loosen or shift during the winding process. The sewing thread begins to wind around the winding drum, avoiding tangled winding, knots, or uneven tightness, thereby improving winding efficiency and quality and reducing production interruptions and defective product rates caused by winding problems.

[0023] 3. The thread-managing device for sewing threads drives the guide ring on the top surface to move by making a reciprocating linear motion along the reciprocating screw through the moving block, thereby guiding the sewing thread to move back and forth in the axial direction of the winding drum. The sewing threads are arranged neatly and tightly on the winding drum, which further improves the uniformity and tightness of the winding, makes the wound sewing threads easier to take out and process later, and improves the convenience and continuity of the entire sewing production process; realizes the synchronous operation of winding, reciprocating thread management and cleaning. When the winding shaft rotates to rewind, the reciprocating screw is driven by the belt drive to rotate to realize the reciprocating thread management action, and at the same time drives the processing roller to rotate to clean the sewing threads, which simplifies the operation process and reduces production costs.

[0024] 4. The thread-managing device for sewing threads assists in thread positioning and conveying the sewing threads during thread management during the rotation of the processing roller, so that the sewing threads can enter the subsequent winding process in an orderly manner, and prevent the sewing threads from getting tangled or knotted when entering, thereby improving production efficiency and reducing the failure rate; the cleaning roller is in friction contact with the outer peripheral wall of the processing roller, and the second gear sleeved on the processing roller is meshed with the tooth groove on the outer peripheral wall of one end of the cleaning roller, so that the cleaning roller can clean the sewing threads during rotation to remove dust, impurities, etc. on the sewing threads.

[0025] 5. The thread-straightening device for sewing threads forms a negative pressure at its air inlet end after the dust suction fan is started, and the air near the open dust suction block is sucked in with impurities. After the air and impurities enter the dust suction fan, they are discharged from the air outlet end and enter the dust collecting bag for collection, thereby achieving the cleaning and collection of impurities, ensuring the clean winding of the sewing thread, ensuring the rapid collection of impurities, and preventing secondary pollution of dust and impurities.

[0035] A servo motor 7 is installed on the rear wall of the support block 3 through a mounting seat. The output shaft of the servo motor 7 is coaxially connected to one of the winding shafts 2. A guide rail 8 is fixedly provided in the middle of the support block 3. A tension spring 9 is sleeved on the outer peripheral wall of the guide rail 8. One end of the tension spring 9 is fixedly connected to the outer wall of the support block 3. A slider 10 is slidably connected to the guide rail 8, and the other end of the tension spring 9 is fixedly connected to the outer wall of the slider 10. A T-shaped frame 11 is fixedly provided on the top surface of the slider 10. Two circular pressure blocks 12 are rotatably connected to the T-shaped frame 11. A winding drum 13 is sleeved on the winding shaft 2. A circular stopper 14 is fixedly provided on the outer wall of one end of the winding shaft 2 close to the support block 3, and the two ends of the winding drum 13 are respectively abutted against the circular stopper 14 and the circular pressure block 12; the circular pressure block 12 exerts a stable pressure on the winding drum 13 to ensure that the winding drum 13 will not loosen or deviate during the winding process.

[0036] A traction wheel 15 is sleeved on the central axis of the reciprocating screw 501, and pulleys 16 are respectively sleeved on the processing roller 601 and the winding shaft 2. The wheel grooves of the two pulleys 16 are respectively driven by friction with the wheel grooves of the traction wheel 15 through the belt 17, thereby realizing the synchronous winding, reciprocating wire arrangement and cleaning work.

[0037] The reciprocating assembly 5 includes a bracket 504, the outer peripheral walls at both ends of the reciprocating screw 501 are respectively rotatably connected to the bracket 504, a round rod 505 is provided at the upper end of the reciprocating screw 501, and the upper end of the moving block 502 is slidingly connected to the round rod 505; the moving block 502 is threadedly connected to the reciprocating screw 501 through a threaded hole and the upper end is slidingly connected to the round rod 505, thereby guiding the sewing thread to reciprocate in the axial direction of the winding drum 13.

[0038] Working principle: After the sewing thread is introduced into the thread management device, it is cleaned by the cleaning assembly 6 and then passes through the guide ring 503. It first reaches the two reel shafts 2 in the middle of the top surface of the thread management platform 1. The rear end of the reel shaft 2 is rotatably connected to the upper end of the support block 3. The first gear 4 sleeved on it engages with each other, so that the two reel shafts 2 can rotate synchronously in opposite directions, thereby driving the sewing thread to start winding around the reel shaft 2;

[0039] At the same time, the two reciprocating components 5 on the top surface of the thread management platform 1 start to operate, and the reciprocating screw 501 rotates. Since the moving block 502 is threadedly connected to the reciprocating screw 501 through the threaded hole and is slidably connected thereto, the moving block 502 will make a reciprocating linear motion on the reciprocating screw 501, and the guide ring 503 on its top surface also moves accordingly, guiding the sewing thread to move back and forth in the axial direction of the winding shaft 2, ensuring that the sewing thread is evenly wound on the winding shaft 2, realizing automatic winding and arranging of the sewing thread, avoiding problems such as tangling of the sewing thread or poor extraction due to uneven winding, and improving the winding quality;

[0040] The output shaft of the servo motor 7 drives a reel 2 coaxially connected thereto to rotate. Since the first gears 4 on the two reel shafts 2 are meshed with each other, the other reel 2 will rotate synchronously in the opposite direction. The reel 13 is sleeved on the reel 2, one end of which is supported by a circular stopper 14 on the reel 2, and the other end is supported by a circular pressure block 12 rotatably connected to the T-shaped frame 11 on the slider 10. Under the action of the tension spring 9, the slider 10 slides along the guide rail 8, so that the circular pressure block 12 applies stable pressure to the reel 13 to ensure that the reel 13 will not loosen or deviate during the reeling process. The sewing thread begins to be wound around the reel 13, avoiding the occurrence of winding chaos, knotting or uneven tightness, thereby improving the reeling efficiency and quality, and reducing the production interruption and defective rate caused by reeling problems.

[0041] The two brackets 504 support the reciprocating screw 501 for rotation. The moving block 502 is threadedly connected to the reciprocating screw 501 through a threaded hole and the upper end is slidably connected to the round rod 505. When the reciprocating screw 501 rotates, the moving block 502 makes a reciprocating linear motion along the reciprocating screw 501, driving the guide ring 503 on the top surface to move, thereby guiding the sewing thread to reciprocate in the axial direction of the winding drum 13. The sewing thread is neatly and tightly arranged on the winding drum 13, further improving the uniformity and tightness of the winding, making the wound sewing thread easier to subsequently take out and process, and improving the convenience and consistency of the entire sewing production process.

[0042] The traction wheel 15 on the central axis of the reciprocating screw 501 is frictionally driven by the belt 17 with the rewinding shaft 2 and the pulley 16 on the processing roller 601, thereby realizing the synchronous winding, reciprocating wire sorting and cleaning. When the rewinding shaft 2 rotates to rewind, the reciprocating screw 501 will be driven by the belt 17 to rotate to realize the reciprocating wire sorting action, and at the same time drive the processing roller 601 to rotate to clean the sewing thread, which simplifies the operation process and reduces production costs.

[0043] Example 2, as Figure 1 , Figure 4 and Figure 5 As shown, on the basis of embodiment 1, the cleaning component 6 includes a column 602, and there are two columns 602. The outer peripheral walls of the two ends of the processing roller 601 are respectively rotatably connected to the columns 602. A cleaning roller 603 is provided at the upper end of the processing roller 601, and the outer peripheral wall of the cleaning roller 603 is in friction contact with the outer peripheral wall of the processing roller 601; during the rotation of the processing roller 601, the auxiliary sewing thread is positioned and transported during the thread arrangement, so that the sewing thread enters the subsequent winding process in an orderly manner, preventing the sewing thread from being entangled, knotted, etc. when entering.

[0044] A second gear 604 is sleeved on the processing roller 601, and a plurality of tooth grooves 605 are provided in a ring array structure on the outer peripheral wall of one end of the cleaning roller 603, and the second gear 604 is meshed and connected with the tooth grooves 605; so that the cleaning roller 603 can clean the sewing thread during the rotation process and remove dust, impurities, etc. on the sewing thread.

[0045] An open dust suction block 606 is fixed between the two columns 602, and a dust suction fan 607 is installed on the top surface of the open dust suction block 606 through a mounting seat. The air inlet end of the dust suction fan 607 is connected to the inside of the open dust suction block 606, thereby realizing the cleaning and collection of impurities and ensuring the clean winding of the sewing thread.

[0046] During use, when the sewing thread passes through the cleaning assembly 6 during the winding process, the processing roller 601 rotates to assist in the positioning and conveying of the sewing thread during the thread arrangement, so that the sewing thread enters the subsequent winding process in an orderly manner, and prevents the sewing thread from being entangled or knotted when entering, thereby improving production efficiency and reducing the failure rate; the cleaning roller 603 is in frictional contact with the outer peripheral wall of the processing roller 601, and the second gear 604 sleeved on the processing roller 601 is meshed with the tooth groove 605 on the outer peripheral wall of one end of the cleaning roller 603, so that the cleaning roller 603 cleans the sewing thread during the rotation process to remove dust, impurities, etc. on the sewing thread;

[0047] During the cleaning process, the dust collecting bag is first installed to the air outlet end of the dust collecting fan 607. The dust and impurities generated during cleaning will be sucked into the open dust collecting block 606 under the action of the dust collecting fan 607. After the dust collecting fan 607 is started, a negative pressure is formed at its air inlet end, and the air near the open dust collecting block 606 is sucked in with impurities. After the air and impurities enter the dust collecting fan 607, they are discharged from the air outlet end and enter the dust collecting bag for collection, thereby realizing the cleaning and collection of impurities, ensuring the clean winding of the sewing thread, ensuring the rapid collection of impurities, and preventing secondary pollution of dust and impurities.

[0048] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
