Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile cotton yarn carding, in particular to a cotton yarn production carding device. BACKGROUND

[0002] The carding machine is used for processing cotton fibers and chemical fibers, and belongs to textile machinery. According to the spinning process, carding is an important process. Its working principle is to open and comb the cotton (fiber) roll sent by the previous process or the oil cotton (chemical fiber) layer supplied by the cotton box, so that all the curled blocks of cotton are basically straightened into single fibers. In this process, broken seeds, impurities and short fibers left by the cleaning process are removed, and then cotton slivers of a certain specification are integrated and stored in the cotton cylinder for use in the doubling process.

[0003] Further description is needed: the fibers and impurities are combed and taken away by the sawtooth of the licker-in roller, and then make rotary motion. In the rotary process, part of the fibers and impurities will leave the sawtooth and suspend in the boundary layer, and advance with the boundary layer airflow. By using the movement law of fibers and impurities in the boundary layer (impurities have large mass and small resistance, fibers have light mass and large resistance), the boundary layer is cut by the dust removal knife to achieve the purpose of adjusting the falling cotton, removing impurities and protecting fibers. The rotating speeds of the licker-in roller, the cylinder and the flat plate in the carding machine are different, and the rotating speeds need to be adjusted according to the actual situation respectively, so that the carding machine cannot complete the work by one motor.

[0004] Through retrieval, Chinese patent No. CN219886255U discloses a textile cotton yarn production carding device. Although it can clean the brush roller and collect dust in the cleaning cavity, it cannot consider the difference in rotating speed between the rollers, and cannot meet the rotating speed requirements of multiple rollers through the same motor, so multiple motors and electrical control are needed, which not only increases the cost investment and the risk of equipment damage, but also makes the electrical control complex, the wiring difficult, and the cotton yarn feeding efficiency improved. In order to make the carding efficient and stable, the rotating speed of the licker-in roller and the cylinder should also be increased accordingly. The increase of the rotating speed of the licker-in roller and the cylinder will lead to the change of airflow intensity and direction, which may affect the carding and impurity removal effect of the fibers. In order to maintain the stability and efficiency of the airflow in the device, the air suction efficiency needs to be increased. SUMMARY

[0031] Please refer to Figure 5 and Figure 8 The connecting shaft 25 and the rotating shaft 18 are provided with a plurality of connecting shafts 25 and rotating shafts 18, the plurality of connecting shafts 25 correspond to the plurality of rotating shafts 18 one by one, and the plurality of connecting shafts 25 correspond to the licker-in roller 5, the breast cylinder 6, the sub cover plate 7, the transfer roller 8, the doffer 9, the main cylinder 10 and the discharge roller 11 one by one, and the first driven sprocket 17 is arranged side by side with the first transmission sprocket 30.

[0032] Please refer to Figure 8 The end of the rotating shaft 18 is slidingly sleeved with the ring cavity 26, the inner diameter of the ring cavity 26 gradually decreases, the fixed tooth ring 27 is provided with a plurality of fixed tooth rings 27, and the inner diameter of the plurality of fixed tooth rings 27 gradually decreases, and the tooth block 23 is meshingly connected with the fixed tooth ring 27.

[0033] Please refer to Figure 8 and Figure 9 The lead screw 29 is slidingly sleeved with the rotating shaft 18, the sleeve ring 21 is slidingly sleeved with the rotating shaft 18, the tooth block 23 is provided with a plurality of tooth blocks 23, and the plurality of tooth blocks 23 are evenly stepped about the central axis of the sleeve ring 21.

[0034] Specifically, in the carding process, the rotation of the first transmission shaft 14 drives the driving sprocket 15 to rotate, so that the first chain 16 on the driving sprocket 15 drives the first driven sprocket 17 to rotate, so that the rotating shaft 18 on the first driven sprocket 17 drives the sleeve ring 21 to rotate through the sliding cavity 19 and the guide block 20, so that the tooth block 23 on the sleeve ring 21 drives the fixed tooth ring 27 to rotate, so that the connecting shaft 25 on the fixed tooth ring 27 rotates, and then the connecting shaft 25 drives the breast cylinder 6 to rotate. At this time, if it is necessary to adjust the speed ratio of the breast cylinder 6 and the feed roller 4, the lead screw 29 outside the rotating body 1 is rotated, so that the lead screw 29 rotates and enters the body 1. At this time, the lead screw 29 will push the guide block 20 to translate along the sliding cavity 19, so that the sleeve ring 21 on the guide block 20 drives the tooth block 23 to translate, so that the tooth block 23 is extruded by the side wall of the ring cavity 26, and the inner diameter of the ring cavity 26 gradually decreases, so that the tooth block 23 is gradually contracted into the groove 22 under pressure, and the return spring 24 is compressed. At this time, the effective radius of the rotation of the tooth block 23 is reduced, the effective radius of the fixed tooth ring 27 connected with the tooth block 23 is increased, and according to the formula of linear velocity and radius It can be known that when the angular velocity of the rotating shaft 18, that is, the angular velocity of the feed roller 4, is constant, the smaller the radius, the smaller the linear velocity. Therefore, the linear velocity of the tooth block 23 after contraction is reduced, so that the linear velocity of the fixed tooth ring 27 driven by the tooth block 23 is reduced. According to the above formula, the linear velocity is reduced, the radius is increased, and the angular velocity must be reduced. Therefore, the rotating speed of the breast cylinder 6 driven by the connecting shaft 25 is reduced, and vice versa. The rotating speed of the breast cylinder 6 is increased, so that the rotating speed ratio between the rollers can be freely adjusted according to the needs. The difference in rotating speed between the rollers can be fully considered, and then the needs of various rotating speeds of the rollers can be met through the same motor 13. Without the participation of various motors 13 and electrical control, not only the cost investment is reduced, and the risk of equipment damage is reduced, but also the electrical control is simple, and the wire arrangement is simple.

[0036] Please refer to Figure 5 , the worm wheel 44 is meshed with the worm 28, and the third chain 39 is slidably sleeved with the fan shell 35 and the side wall of the machine body 1.

[0037] Please refer to Figure 5 , the second transmission sprocket 40 and the second transmission shaft 43 are both rotatably sleeved with the side wall of the machine body 1, and the paddles 37 at both ends of the rotating shaft 36 are symmetrically arranged about the bisector plane of the fan shell 35.

[0038] Specifically, in the process of improving the cotton yarn feeding efficiency, the motor 13 drives the feed roller 4 to increase the rotating speed through the first transmission shaft 14, and the first transmission shaft 14 drives the connecting shaft 25 to increase the rotating speed through the above process, so that the rotating speed of the worm 28 on the connecting shaft 25 is increased, the rotating speed of the worm wheel 44 driven by the worm 28 is increased, and then the worm wheel 44 accelerates the rotation of the driven helical gear 41 on the driving helical gear 42 through the second transmission shaft 43, so that the rotating speed of the driven helical gear 41 on the driving helical gear 42 is increased, the rotating speed of the third driven sprocket 38 and the rotating shaft 36 is increased through the third chain 39, and the paddles 37 on the rotating shaft 36 are accelerated to rotate, so that the air suction efficiency of the paddles 37 is improved, and the air flow is transmitted to the machine body 1 through the pipe 45, so as to increase the air suction efficiency, keep the stability and efficiency of the air flow in the device, and make the cotton combing stable and efficient, so as to ensure the combing effect and impurity removal effect of the fiber.

[0041] Specifically, in the process of rotating the breast roller 6 in the opposite direction of the feed roller 4, when the breast roller 6 needs to rotate in the opposite direction of the taker-in 5, the taker-in 5 rotates in the same direction as the feed roller 4, the shaft 18 drives the second driven sprocket 32 to rotate through the first drive sprocket 30 and the second chain 31, so that the driven gear 34 rotates through the driving gear 33 on the second driven sprocket 32, at this time, the rotation direction of the driven gear 34 is opposite to the rotation direction of the feed roller 4, so that the driven gear 34 drives the connecting shaft 25 on the taker-in 5 to rotate in the opposite direction through the other shaft 18, so that the taker-in 5 rotates in the same direction as the feed roller 4, and the breast roller 6 rotates in the opposite direction of the feed roller 4, so that the breast roller 6 rotates in the opposite direction of the taker-in 5. Through the above two transmission modes, the rotation direction between the rollers can be randomly converted, so that the cotton carding device can normally card cotton, and the quality and autonomy of the cotton carding are ensured.

[0042] The working principle and use process of the present application: when cotton is needed, the cotton roll is put into the feed inlet 3, and the motor 13 is started, so that the motor 13 drives the feed roller 4 to rotate through the first transmission shaft 14, so that the feed roller 4 cooperates with the feed inlet 3 to guide the cotton roll, so that the cotton roll contacts the taker-in 5, and the taker-in 5 holds and preliminarily cards the cotton roll, the preliminarily carded fiber is transferred to the breast roller 6, the breast roller 6 cooperates with the auxiliary cover plate 7 to further card, and is gradually broken down into smaller fiber bundles, and the smaller fiber bundles are transferred to the doffer 9 by the transfer roller 8, the doffer 9 agglomerates the fibers into a fiber layer, and finally the main roller 10 and the main cover plate 12 are used for sufficient carding, and the fibers after sufficient carding are transferred to the discharge roller 11 by the main roller 10, the discharge roller 11 agglomerates the fibers into a fiber layer again and is transmitted to the collection roller 2, and the cotton carding operation is completed.

[0043] During the above-mentioned carding process, the rotation of the first transmission shaft 14 drives the driving sprocket 15 to rotate, so that the first chain 16 on the driving sprocket 15 drives the first driven sprocket 17 to rotate, so that the shaft 18 on the first driven sprocket 17 drives the sleeve ring 21 to rotate through the sliding cavity 19 and the guide block 20, so that the tooth block 23 on the sleeve ring 21 drives the fixed tooth ring 27 to rotate, so that the connecting shaft 25 on the fixed tooth ring 27 rotates, and further drives the breast roller 6 to rotate, at this time, if the speed ratio of the breast roller 6 and the feed roller 4 needs to be adjusted, the lead screw 29 outside the rotating body 1 is rotated and enters the body 1, at this time, the lead screw 29 pushes the guide block 20 to translate along the sliding cavity 19, so that the sleeve ring 21 on the guide block 20 drives the tooth block 23 to translate, so that the tooth block 23 is extruded by the side wall of the ring cavity 26, and the inner diameter of the ring cavity 26 gradually decreases, so that the tooth block 23 is gradually shrunk into the groove 22 under pressure and compresses the return spring 24, at this time, the effective radius of the rotation of the tooth block 23 is reduced, and the effective radius of the fixed tooth ring 27 connected with the tooth block 23 is increased, according to the formula of linear velocity and radius It can be seen that when the angular velocity of the rotating shaft 18, i.e. the angular velocity of the feed roller 4, is constant, the smaller the radius, the smaller the linear velocity, so that the linear velocity of the tooth block 23 after contraction is reduced, the linear velocity of the fixed tooth ring 27 driven by the tooth block 23 is reduced, according to the above formula, the linear velocity is reduced, the radius is increased, and the angular velocity is necessarily reduced, so that the rotating speed of the breast dial 6 driven by the connecting shaft 25 is reduced, and vice versa, so that the rotating speed ratio between the rollers can be freely adjusted according to the requirements, the difference in rotating speed between the rollers can be fully considered, and the requirements of various rotating speeds of the rollers can be met through the same motor 13, without the participation of various motors 13 and electrical control, not only reducing the cost investment and reducing the risk of equipment damage, but also making the electrical control simple and the wire arrangement simple;

[0044] In the above process, the rotating direction of the breast dial 6 is opposite to that of the feed roller 4, when the breast dial 6 and the carding roller 5 need to rotate in opposite directions, and the carding roller 5 and the feed roller 4 rotate in the same direction, the rotating shaft 18 drives the second driven sprocket 32 to rotate through the first drive sprocket 30 and the second chain 31, so that the driving gear 33 on the second driven sprocket 32 drives the driven gear 34 to rotate, at this time, the rotating direction of the driven gear 34 is opposite to that of the feed roller 4, so that the driven gear 34 drives the connecting shaft 25 on the carding roller 5 to reverse through another rotating shaft 18, so that the carding roller 5 and the feed roller 4 rotate in the same direction, and the rotating direction of the breast dial 6 is opposite to that of the feed roller 4, so that the breast dial 6 and the carding roller 5 rotate in opposite directions. Through the above two transmission modes, the rotating direction between the rollers can be randomly converted, so that the cotton carding device can normally card cotton, and the quality and autonomy of the cotton carding are ensured.

[0045] When the cotton feeding efficiency is improved, the motor 13 drives the rotating speed of the feed roller 4 to increase through the first transmission shaft 14, and at the same time, the first transmission shaft 14 drives the rotating speed of the connecting shaft 25 to increase through the above process, so that the rotating speed of the worm 28 on the connecting shaft 25 is increased, the rotating speed of the worm wheel 44 driven by the worm 28 is increased, and then the worm wheel 44 accelerates the rotation of the driving bevel gear 42 through the second transmission shaft 43, so that the driven bevel gear 41 on the driving bevel gear 42 accelerates the rotation of the second transmission sprocket 40, so that the second transmission sprocket 40 accelerates the rotation of the third driven sprocket 38 and the rotating shaft 36 through the third chain 39, so that the paddle 37 on the rotating shaft 36 accelerates the rotation, so that the air suction efficiency of the paddle 37 is improved, and the air flow is transmitted into the machine body 1 through the duct 45, so as to increase the air suction efficiency, keep the stability and efficiency of the air flow in the device, and make the cotton carding efficiently and stably, so as to ensure the carding effect and impurity removal effect of the fiber, and complete the operation.
