Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cotton yarn processing, in particular to a cotton yarn strip cutting device for cotton yarn processing. Background Art
[0002] Cotton yarn is made from cotton fibers through a spinning process. After plying, it becomes cotton thread. Depending on the spinning process, it can be divided into carded yarn and combed yarn. Cotton yarn has a wide range of uses. It can be used as weaving yarn, such as bed sheets, quilt covers, curtains, and other home textiles. It can also be used as knitting yarn. Combed yarn, in particular, can be used to produce high-quality textiles such as high-end sweatshirts and fine poplin. Cotton yarn can also be used to produce specialty industrial products such as electrical yellow wax cloth, tire cord fabric, high-speed sewing thread, and embroidery thread. During processing, cotton yarn is cut into different lengths according to production needs for easy subsequent use and storage.
[0003] After searching, a cotton yarn strip cutting device for cotton yarn processing with the announcement number CN220057453U was found. This utility model relates to the technical field of cotton yarn processing, and in particular to a cotton yarn strip cutting device for cotton yarn processing. In view of the background technology, it is proposed that the existing cotton yarn strips are prone to tilting during the transportation process of the cutting device. The following scheme is now proposed, including a conveying frame, the outer surfaces of both sides of the conveying frame are provided with openings, and the inner surface of the conveying frame is rotatably connected to the conveying roller, the outer surfaces of the two conveying rollers are sleeved with the same conveyor belt, and a motor is installed on the outer surface of one side of the conveying frame. The two electric telescopic rods of the utility model drive the lower pressure roller downward to cooperate with the positioning roller to limit the conveying of the cotton yarn strips, and then the two second electric slides can drive the adjusting roller to move horizontally, so that the cotton yarn strips between the guide roller and the adjusting roller can be adjusted to a vertical and more tense state, and then the cutting assembly can cut the cotton yarn strips between the guide roller and the adjusting roller, thereby improving the efficiency of the cotton yarn strip cutting work.
[0004] In the current existing technology:
[0005] The current cutting devices all use two conveyor rollers to straighten the cotton yarn and cut it.

[0030] Specific examples are given below.
[0031] See also Figure 1-Figure 3 The utility model provides a cotton yarn cutting device for cotton yarn processing, including a cutting device main body 1 and a conveying roller 2. A conveying roller 2 is provided on the left side of the cutting device main body 1, and a limiting roller 3 is provided above the conveying roller 2. A cotton yarn main body 4 is provided between the conveying roller 2 and the limiting roller 3. A winding roller 5 is provided on the right side of the cutting device main body 1. A first sprocket 6 is provided in front of the conveying roller 2, and a second sprocket 8 is provided in front of the winding roller 5.

[0032] During operation, the first motor 9 is started to drive the first sprocket 6 to rotate. Since the first sprocket 6 and the second sprocket 8 are driven by the transmission chain 7, under the action of friction, the transmission chain 7 is pushed to drive the second sprocket 8 to rotate synchronously, so that the cotton yarn main body 4 is input from the conveying roller 2 to the inside of the cutting device main body 1, and finally wound by the winding roller 5. A limiting roller 3 is provided to prevent the cotton yarn main body 4 from being offset during the input process.
[0033] Further, such as Figures 1-4 As shown, a support frame 16 is provided at the rear of the cutting device body 1, and a support screw rod 14 is provided in the middle of the support frame 16. The input end of the support screw rod 14 is connected to the second motor 15, and support slide rods 13 are provided on both sides of the support frame 16. The outside of the support slide rod 13 and the support screw rod 14 is sleeved with a first movable plate 12, and fixed shafts are provided on both sides in front of the first movable plate 12. The outside of the fixed shaft is sleeved with a movable roller 10, and movable grooves 11 are provided on both sides of the rear of the cutting device body 1. The second motor 15 is fixedly connected to the support screw rod 14, and the support screw rod 14 is threadedly matched with the first movable plate 12. The support slide rod 13 passes through the first movable plate 12, and the first movable plate 12 is fixedly connected to the fixed shaft. The fixed shaft is movably pinned to the movable roller 10, and the fixed shaft passes through the movable groove 11 and is adapted to the movable groove 11.
[0034] During operation, the second motor 15 starts and drives the supporting screw rod 14 to rotate. Under the action of the thread, the first movable plate 12 is pushed down along the supporting slide rod 13. Since the first movable plate 12 is fixedly connected to the fixed shaft, the fixed shaft is movably pinned to the movable roller 10, and the fixed shaft passes through the movable groove 11 and adapts to the movable groove 11, so that the fixed shaft drives the movable roller 10 to move down along the movable groove 11 to press the cotton yarn main body 4. On the one hand, it can prevent the cotton yarn main body 4 from deviating during the transportation process, and on the other hand, it cooperates with the tensioning roller 19 to enable the cotton yarn main body 4 to be tensioned.
[0035] Further, such as Figure 2-Figure 3 As shown, a support plate 17 is arranged between the two movable rollers 10, and a second movable plate 18 is arranged on both sides of the top of the support plate 17, and a tensioning roller 19 is arranged on the top of the second movable plate 18. An adjusting rod 20 is arranged between the second movable plate 18 and the support plate 17, and a sliding block 21 is arranged at the bottom of the adjusting rod 20. A guide slide rod 22 is passed through the interior of the sliding block 21, and a support spring 23 is sleeved on the side of the guide slide rod 22 away from the central axis of the support plate 17. The support plate 17 is movably pinned to the second movable plate 18, and the second movable plate 18 is movably pinned to the tensioning roller 19. The adjusting rod 20 is movably pinned to the second movable plate 18 and the sliding block 21 respectively. The guide slide rod 22 passes through the sliding block 21, and the sliding block 21 is elastically connected to the support plate 17 through the support spring 23.
[0036] During operation, the cotton yarn main body 4 bypasses the movable roller 10 and is transported from above the tensioning roller 19. When the movable roller 10 presses down the cotton yarn main body 4, the cotton yarn main body 4 exerts pressure on the tensioning roller 19. Since the support plate 17 is movably pinned to the second movable plate 18, the adjusting rod 20 is movably pinned to the second movable plate 18 and the sliding block 21 respectively. Under the action of the adjusting rod 20, the sliding block 21 is pushed to squeeze the support spring 23 to generate elastic force. Under the action of the elastic force, the tensioning roller 19 is always driven to be close to the cotton yarn main body 4, thereby tensioning the cotton yarn main body 4.
[0037] Further, such as Figure 1 、 Figure 2 and Figure 5As shown, a lower cutting knife 24 is provided in the middle of the top of the support plate 17, an upper cutting knife 25 is provided above the lower cutting knife 24, a cutting knife seat 26 is provided on the top of the upper cutting knife 25, a connecting rod 27 is provided on the top of the cutting knife seat 26, an eccentric wheel 28 is provided on the left side of the top of the connecting rod 27, and the input end of the eccentric wheel 28 is connected to the third motor 29, and guide grooves 30 are provided on the front and rear sides of the cutting knife seat 26. Guide sliders 31 are provided on the front and rear sides of the inside of the cutting device body 1, the upper cutting knife 25 is fixedly connected to the cutting knife seat 26, the connecting rod 27 is movably pinned to the cutting knife seat 26 and the eccentric wheel 28 respectively, the eccentric wheel 28 is fixedly connected to the third motor 29, and the guide groove 30 is adapted to the guide slider 31.
[0038] During operation, the third motor 29 starts to drive the eccentric wheel 28 to rotate. Since the connecting rod 27 is movably pinned to the cutting knife seat 26 and the eccentric wheel 28 respectively, when the eccentric wheel 28 rotates, the connecting rod 27 pushes the cutting knife seat 26 to move downward along the guide slider 31 under the action of the guide slot 30, thereby moving the upper cutting knife 25 downward and cooperating with the lower cutting knife 24 to cut the tensioned cotton yarn body 4.
[0039] Working principle:
[0040] First, the first motor 9 is started to drive the first sprocket 6 to rotate. Since the first sprocket 6 and the second sprocket 8 are driven by the transmission chain 7, under the action of friction, the transmission chain 7 drives the second sprocket 8 to rotate synchronously, so that the cotton yarn body 4 is input from the conveying roller 2 to the inside of the cutting device body 1, and finally is reeled by the reeling roller 5. The limiting roller 3 is provided to prevent the cotton yarn body 4 from deflecting during the input process.
[0041] Secondly, the second motor 15 is started to drive the support screw 14 to rotate. Under the action of the thread, the first movable plate 12 is pushed down along the support slide rod 13. Since the first movable plate 12 is fixedly connected to the fixed shaft, the fixed shaft is movably pinned to the movable roller 10, and the fixed shaft passes through the movable groove 11 and adapts to the movable groove 11, so that the fixed shaft drives the movable roller 10 to move down along the movable groove 11, thereby pressing the cotton yarn body 4. On the one hand, it can prevent the cotton yarn body 4 from deflecting during the conveying process, and on the other hand, it cooperates with the tensioning roller 19 to enable the cotton yarn body 4 to be tensioned.
[0042] Subsequently, the cotton yarn body 4 passes around the movable roller 10 and is transported from above the tensioning roller 19. When the movable roller 10 presses down the cotton yarn body 4, the cotton yarn body 4 applies pressure to the tensioning roller 19. Since the support plate 17 is movably pinned to the second movable plate 18, the adjusting rod 20 is movably pinned to the second movable plate 18 and the sliding block 21 respectively. Under the action of the adjusting rod 20, the sliding block 21 is pushed to squeeze the support spring 23 to generate elastic force. Under the action of the elastic force, the tensioning roller 19 is always driven to be in close contact with the cotton yarn body 4, thereby tensioning the cotton yarn body 4.
[0043] Finally, the third motor 29 is started to drive the eccentric wheel 28 to rotate. Since the connecting rod 27 is movably pinned to the cutting knife seat 26 and the eccentric wheel 28 respectively, when the eccentric wheel 28 rotates, the connecting rod 27 pushes the cutting knife seat 26 to move downward along the guide slider 31 under the action of the guide groove 30, thereby causing the upper cutting knife 25 to move downward and cooperate with the lower cutting knife 24 to cut the tensioned cotton yarn body 4.
[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
