Technical Field

[0001] This utility model relates to the field of yarn equipment technology, specifically to a loose yarn structure. Background Technology

[0002] When processing yarn, it is necessary to loosen the yarn to meet the processing requirements and prevent phenomena such as uneven dyeing or tangling caused by the yarn not being loose.

[0003] However, existing loosening equipment simply installs rows of carding needles at the yarn inlet. Although the yarn passes through the carding needles, it can improve the looseness of the yarn, but it is still not effective in improving the looseness of the yarn. Therefore, it has certain defects.

[0004] Therefore, in order to improve the looseness of the yarn and avoid uneven dyeing and knotting during dyeing or winding, thereby overcoming the shortcomings of the prior art, a loose yarn structure is hereby proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a loose yarn structure that solves the problem that existing loose yarn structures cannot improve the degree of yarn looseness.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a yarn loosening structure, comprising two sets of mounting bases, with mounting plates mounted on the surfaces of the mounting bases. A loosening structure for improving yarn looseness is installed between the two sets of mounting bases. The loosening structure includes a carding structure and a blowing structure, with the blowing structure located within the carding structure. The carding structure includes a driving structure and a carding cylinder structure, with the carding cylinder structure connected to the driving structure. The carding cylinder structure includes carding rollers and carding needles. Two sets of carding rollers are provided, both connected to the driving structure, and the two sets of carding rollers reverse direction through the driving structure. The carding roller rotates, and the surface of the carding roller has openings arranged in a ring array. Carding needles are installed on the surface of the carding roller. The blowing structure is located inside the carding roller and includes an inner mounting plate, bearings, air ducts, and connecting pipes. The air ducts are inserted into the carding roller from one side of the drive structure. The inner mounting plate is symmetrically installed inside the carding roller. The surface of the inner mounting plate has a circular opening. The bearing is installed in the opening. The surface of the carding roller is connected to the inner ring of the bearing. The surface of the carding roller has an opening. The outer end face of the carding roller is connected to the connecting pipe. The connecting pipe is connected to the exhaust fan through a pipe. The surfaces of the two sets of air ducts have openings on opposite sides.

[0007] Furthermore, through the above technical solution, the carding needles on the surfaces of the two sets of carding rollers are arranged in an alternating pattern.

[0008] Furthermore, the drive structure includes a stepper motor, a coupling, a connecting shaft, and gears; the stepper motor is mounted on the outer surface of the mounting plate, and its output end is connected to the connecting shaft through the coupling. The connecting shaft is connected to the carding roller through bolts. Gears are mounted on the surface of another set of connecting shafts, and the two sets of gears mesh and drive each other. The air duct extends through the connecting shaft into the carding roller.

[0009] As a preferred technical solution, the outer surface of the mounting plate is also fitted with a protective box, which encloses the two sets of gears.

[0010] Furthermore, bearing seats are installed on both the surface and inner side of the mounting plate, and the inner ring of the bearing seat is connected to the surface of the connecting shaft.

[0011] As a preferred technical solution, side mounting plates are installed on both the front end face of the mounting plate and the rear side face of the mounting base, and a combing needle is installed on the upper end face of the side mounting plate.

[0012] Furthermore, the adjacent two groups of combing needles are arranged alternately.

[0013] Compared with the prior art, the present invention provides a loose yarn structure, which has the following beneficial effects:

[0014] 1. This loose structure, through carding rollers, air ducts, connecting pipes, carding needles, a drive structure, and gears, enables the two sets of carding rollers to rotate via gears, causing the carding needles to rotate and card the yarn between the two sets of carding rollers. During the carding process, air is blown through the air ducts, allowing the air to come into contact with the yarn through the openings on the surface of the carding rollers, thereby further improving the looseness of the yarn. Based on the above structural arrangement, it overcomes the problems of insufficient yarn looseness in the prior art, which can lead to uneven dyeing during dyeing and knotting during winding.

[0023] 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. Example

[0024] Please see Figure 1-7 This utility model provides the following technical solution: a yarn loosening structure, including two sets of mounting bases 1, with mounting plates 2 mounted on the surface of the mounting bases 1. A loosening structure to improve the looseness of the yarn is installed between the two sets of mounting bases 1. The loosening structure includes a carding structure and a blowing structure. The blowing structure is located inside the carding structure. The carding structure includes a driving structure and a carding cylinder structure. The carding cylinder structure is connected to the driving structure. The carding cylinder structure includes carding rollers 9 and carding needles 10. The carding rollers 9 are arranged in two sets, both connected to the driving structure. The two sets of carding rollers 9 rotate in opposite directions through the driving structure. Furthermore, the surface of the carding rollers 9 is arranged in a ring array. An opening is provided, and a second combing needle 10 is installed on the surface of the combing roller 9. The blowing structure is located inside the combing roller 9 and includes an inner mounting plate 11, a bearing 12, an air duct 13, and a connecting pipe 14. The air duct 13 is inserted into the combing roller 9 from one side of the drive structure. The inner mounting plate 11 is symmetrically installed inside the combing roller 9. The surface of the inner mounting plate 11 has a circular opening, and the bearing 12 is installed in the opening. The surface of the combing roller 9 is connected to the inner ring of the bearing 12. The surface of the combing roller 9 has an opening, and the outer end face of the combing roller 9 is connected to the connecting pipe 14. The connecting pipe 14 is connected to the exhaust fan through a pipe. The two sets of air ducts 13 have openings on opposite sides.

[0025] In this implementation scheme, the specific working principle is as follows: When the yarn passes between the two sets of carding rollers 9 during operation, the driving structure drives the two sets of carding rollers 9 to rotate in opposite directions, which in turn drives the carding needles 10 to rotate, thereby carding the yarn. In order to improve the carding effect, the connection between the connecting pipe 14 and the exhaust fan allows the air to be blown onto the yarn through the opening on the surface of the air duct 13, thereby further improving the loosening of the yarn in conjunction with the carding needles 10. Secondly, in order to provide support for the air duct 13, the inner mounting plate 11 and the bearing 12 are used. The bearing 12 mainly provides support force for the air duct 13 and can prevent the air duct 13 from being affected by the rotation of the carding rollers 9.

[0026] Based on the above, in order to improve the combing effect of the yarn, please refer to the following: Figure 2 It can be seen that the combing needles 10 on the surfaces of the two sets of combing rollers 9 are arranged alternately.

[0027] For details on how the drive structure drives the two sets of combing rollers 9 to rotate in opposite directions, please refer to [link to relevant documentation]. Figure 4 and Figure 6 As can be seen, the drive structure includes a stepper motor 3, a coupling 7, a connecting shaft 8, and a gear 16. The stepper motor 3 is mounted on the outer surface of the mounting plate 2, and its output end is connected to the connecting shaft 8 through the coupling 7. The connecting shaft 8 is connected to the carding roller 9 through bolts. Gears 16 are mounted on the surface of another set of connecting shafts 8. The two sets of gears 16 mesh and drive each other. The air duct 13 passes through the connecting shaft 8 and extends into the carding roller 9. The stepper motor 3 drives the connecting shaft 8 to rotate, which in turn drives the connecting shaft 8 at the other end to rotate through the carding roller 9. Through the action of the gears 16, the other set of carding rollers 9 is driven to rotate, thereby achieving reverse rotation.

[0028] To prevent dust from damaging gear 16, please refer to [the relevant documentation]. Figure 5 As can be seen, a protective box 6 is also installed on the outer surface of the mounting plate 2, which encloses the two sets of gears 16.

[0029] To improve the smoothness of rotation of connecting shaft 8, please refer to [link / reference needed]. Figure 3 , Figure 4 and Figure 5 As can be seen, bearing seats 15 are installed on both the surface and the inner side of the mounting plate 2, and the inner ring of the bearing seat 15 is connected to the surface of the connecting shaft 8.

[0030] For further details on improving yarn looseness, please refer to [link / reference needed]. Figure 1 , Figure 3 , Figure 4 and Figure 5As can be seen, side mounting plates 4 are installed on the front end face of mounting plate 2 and the rear side face of mounting base 1. Combing needles 5 are installed on the upper end face of side mounting plate 4. Combing needles 5 are also installed on the front and rear sides of mounting base 1, thereby improving the looseness of the yarn.

[0031] Based on the above, in order to further improve the looseness of the yarn, please refer to the following: Figure 3 It can be seen that the two adjacent groups of combing needles are arranged alternately.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
