Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, to a multi-group fiber roller feeding structure. Background Technology

[0002] In the textile industry, when processing core yarns, the spray gun requires a feeding mechanism to feed the core yarns into the machine. This feeding mechanism typically uses two feed rollers working in tandem, with the core yarn passing between them and fed in through friction. However, existing feeding mechanisms have several problems: firstly, they cannot simultaneously feed multiple core yarns at different speeds; secondly, the feed rollers cannot rotate actively to feed the yarns; instead, the core yarns are passively fed in by the traction of a motor on the spray gun, resulting in inconsistent core yarn tension. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0003] The purpose of this invention is to provide a multi-group fiber roller feeding structure, aiming to solve at least one of the technical problems existing in the prior art. To achieve the above objective, the technical solution adopted is as follows:

[0004] A multi-group fiber roller feeding structure includes a feeding mechanism and a rolling mechanism;

[0005] The feeding mechanism includes a fixed mounting base, on which a first horizontal shaft is mounted. Multiple hollow shafts are rotatably mounted on the first horizontal shaft. Both ends of the multiple hollow shafts form a stepped structure. Rollers of the same outer diameter are fixedly mounted on the same end of each of the multiple hollow shafts, and a driven gear is fixedly mounted on the other end of each. Each hollow shaft is equipped with a drive motor, and a drive gear is fixedly mounted on the output shaft of the drive motor and meshes with the paired driven gear.

[0006] The roller pressing mechanism includes a fixed mounting plate, on which a bracket is rotatably mounted. A second horizontal shaft is mounted on the bracket, ensuring that the first horizontal shaft is parallel to the second horizontal shaft. Multiple pressure rollers are rotatably mounted on the second horizontal shaft, with each pressure roller corresponding to a roller. When the bracket is rotated, the corresponding pressure roller and roller can interfere with each other.

[0007] Preferably, the outer circumferential surface of the roller is configured as a concave arc surface.

[0008] Preferably, the outer circumferential surface of the pressure roller is configured as a convex arc surface.

[0009] Preferably, a crossbeam is connected to the mounting plate, the crossbeam is located above the roller and the pressure roller, and multiple core wire guide cylinders are provided on the crossbeam.

[0010] Preferably, the mounting base and the mounting plate are fixedly connected by a connecting rod.

[0011] Preferably, the bracket is U-shaped and consists of a crossbar and two uprights connected together.

[0012] Preferably, a through hole is provided on the crossbar, and a fixed shaft is fixed in the through hole. One end of the fixed shaft protrudes from the through hole, and the end of the fixed shaft protruding from the through hole is rotatably connected to the mounting plate through a bearing.

[0013] Preferably, the second horizontal axis is fixedly installed between the two vertical poles.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention relates to a multi-set fiber roller feeding structure. A drive motor drives rollers to rotate and cooperate with pressure rollers to actively feed the core yarn. Simultaneously, it can synchronize with the output motor on the spray gun to ensure consistent core yarn tension.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1 As shown, a preferred embodiment of this utility model provides a multi-group fiber roller feeding structure, which includes a feeding mechanism and a rolling mechanism.

[0025] like Figure 2 As shown, the feeding mechanism includes a mounting base 1, which is fixedly mounted on the frame of the spraying machine. A first horizontal shaft 2 is fixedly mounted on the mounting base 1. Multiple hollow rotating shafts 3 are rotatably mounted on the first horizontal shaft 2, and in this embodiment there are six layers. Specifically, from the inside out, the first layer of hollow rotating shafts is rotatably mounted on the first horizontal shaft 2 through bushings or bearings. Each of the next five layers of hollow rotating shafts is rotatably mounted on the inner layer of hollow rotating shafts through bushings or bearings.

[0026] like Figure 3 As shown, both ends of the six-layer hollow rotating shaft 3 are formed into stepped structures 4. Rollers 5 with the same outer diameter are fixedly mounted on the same end of the six-layer hollow rotating shaft. There is a gap between two adjacent rollers 5 to ensure that the rotation of two adjacent rollers 5 does not affect each other. A driven gear 6 is fixedly mounted on the other end. Similarly, there is a gap between two adjacent driven gears 6.

[0027] Each hollow rotating shaft 3 is equipped with a drive motor 7. In this embodiment, six drive motors 7 are configured. All six drive motors 7 are mounted on the mounting base 1. A drive gear 8 is fixedly mounted on the output shaft of each drive motor 7 and meshes with a paired driven gear 6. The drive motor 7 drives the corresponding hollow rotating shaft 3 to rotate through the output shaft, drive gear 8 and driven gear 6 in sequence, thereby causing the rollers 5 on the hollow rotating shaft 3 to rotate synchronously.

[0028] Based on the above settings, the six rollers 5 can be driven to rotate independently. By setting the speed of the drive motor 7, feeding at the same speed or at a different speed can be achieved.

[0029] like Figure 4As shown, the roller pressing mechanism includes a mounting plate 9, which is fixedly mounted on the frame of the fabric spraying machine. The mounting base 1 and the mounting plate 9 are fixedly connected by a connecting rod 10. A bracket is rotatably mounted on the mounting plate 9. Specifically, the bracket is U-shaped and is composed of a crossbar 11 and two uprights 12. A through hole is provided on the crossbar 11, which is set along the length of the crossbar 11. A fixed shaft 13 is fixed in the through hole, and one end of the fixed shaft 13 protrudes from the through hole. The end of the fixed shaft 13 protruding from the through hole is rotatably connected to the mounting plate 9 through a bearing, ensuring that the fixed shaft 13 is arranged parallel to the first crossbar 2. A second crossbar 14 is fixedly arranged between the two uprights 12, ensuring that the first crossbar 2 and the second crossbar 14 are arranged parallel to each other. Multiple pressure rollers 15 are rotatably mounted on the second crossbar 14. In this embodiment, six pressure rollers 15 are mounted, and the six pressure rollers 15 correspond one-to-one with the six rollers 5.

[0030] When the support is rotated, interference will occur between any pair of corresponding pressure rollers 15 and rollers 5. Under the action of gravity, the outer circumferential surface of the pressure roller 15 will contact the outer circumferential surface of the roller 5. Furthermore, the outer circumferential surface of the roller 5 is set as a concave arc surface, and the outer circumferential surface of the pressure roller 15 is set as a convex arc surface that matches the concave arc surface.

[0031] A crossbeam 16 is connected to the mounting plate 9. The crossbeam 16 is located above the roller 5 and the pressure roller 15. Multiple core wire guide cylinders 17 are provided on the crossbeam 16. In this embodiment, six core wire guide cylinders 17 are provided, each corresponding to one of the six rollers 5. Their function is to guide the core wire.

[0032] In summary, the multi-set fiber roller feeding structure described in this embodiment of the invention achieves active feeding of the core yarn by driving the rollers to rotate via a drive motor and cooperating with the pressure rollers. Simultaneously, it can be synchronized with the output motor on the spray gun to ensure consistent core yarn tension. Furthermore, multiple core yarns can be fed simultaneously during blending, and the feeding speeds of these multiple core yarns can be set to the same speed or differential speed to meet different process requirements.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
