Description

Technical Field

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

[0002] In the textile industry, when processing the core yarn in a spray gun, a feeding mechanism is needed to feed the core yarn into the machine. Existing feeding mechanisms typically use two feed rollers working in tandem, with the core yarn passing between them and fed in through friction. These existing mechanisms have two main problems: first, the gap between the two feed rollers is either not adjustable or very cumbersome to adjust, resulting in poor applicability to core yarns of different specifications; second, the passive feeding of the core yarn, achieved through the traction of the output motor on the spray gun, leads to inconsistent tension.

[0003] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a core wire 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:

[0005] A core wire roller feeding structure includes a mounting base, on which a feeding roller is rotatably mounted. The feeding roller is driven to rotate by a drive motor. A roller pressing device is also provided on the mounting base. The roller pressing device includes a bracket and a pressure roller. The bracket is rotatably mounted on the mounting base, and the pressure roller is rotatably mounted on the bracket, ensuring that the axis of the pressure roller is parallel to the axis of the feeding roller. When the bracket is rotated, interference can be caused between the pressure roller and the feeding roller.

[0006] Preferably, the feed roller has a first through hole along the axial direction, a first rotating shaft is fixed in the first through hole, and one end of the first rotating shaft protrudes from the first through hole. The drive motor is mounted on the mounting base, and the output shaft of the drive motor is connected to the end of the first rotating shaft protruding from the first through hole.

[0007] Preferably, the bracket is U-shaped and consists of a crossbar and two uprights connected together.

[0008] Preferably, the crossbar has a second through hole, a second rotating shaft is fixed in the second through hole, and one end of the second rotating shaft protrudes from the second through hole. The end of the second rotating shaft protruding from the second through hole is rotatably connected to the mounting base through a bearing.

[0009] Preferably, both uprights have elongated through holes at their ends along their length. One end of the elongated through hole near the end face of the upright has a notch, and the other end has a countersunk hole in which a spring is installed. The pressure roller has a third through hole along its axial direction, and a third rotating shaft is installed in the third through hole. The pressure roller can rotate freely. Both ends of the third rotating shaft protrude from the third through hole and extend into the corresponding elongated through hole, and can slide along the length of the elongated through hole. Under the action of the spring, the pressure roller can be tightly fitted with the feed roller.

[0010] Preferably, a limiting shaft is provided at the notch position of the through hole to prevent the third rotating shaft from sliding out of the through hole.

[0011] Preferably, a limit block is provided on the mounting base to limit the rotation of the bracket.

[0012] Preferably, a handle is fixed on the crossbar for holding the handle and rotating the bracket.

[0021] 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.

[0022] 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.

[0023] like Figure 1 As shown, a preferred embodiment of this utility model provides a core wire roller feeding structure, which includes a mounting base 1, a feeding roller 2, a drive motor 3, and a roller pressing device.

[0024] Mounting base 1 is fixedly mounted on the frame of the spraying machine. Drive motor 3 is mounted on mounting base 1 and is used to drive the feed roller 2 to rotate. Specifically, the feed roller 2 has a first through hole along the axial direction. A first rotating shaft 4 is fixed in the first through hole. One end of the first rotating shaft 4 protrudes from the first through hole. The output shaft of drive motor 3 is connected to the end of the first rotating shaft 4 that protrudes from the first through hole.

[0025] The roller pressing device includes a support 5 and a pressure roller 6, such as Figure 2 As shown, the bracket 5 is U-shaped and is formed by a crossbar 7 and two uprights 8 fixedly connected together.

[0026] The bracket 5 is rotatably mounted on the mounting base 1. Specifically, a second through hole is provided on the crossbar 7 along the length of the crossbar 7. A second rotating shaft 9 is fixed in the second through hole, and one end of the second rotating shaft 9 protrudes from the second through hole. The end of the second rotating shaft 9 protruding from the second through hole is rotatably connected to the mounting base 1 through a bearing, and ensures that the second rotating shaft 9 is parallel to the first rotating shaft 4.

[0027] Furthermore, a handle 10 is fixed on the crossbar 7 for holding the handle 10 to rotate the bracket 5.

[0028] The pressure roller 6 is rotatably mounted on the bracket 5. Specifically, both uprights 8 have elongated through holes 11 at their ends along the length of the uprights 8. Further, one end of the elongated through hole 11 near the end face of the upright 8 has a notch to facilitate the insertion of the third rotating shaft 12 described below, and the other end has a countersunk hole in which a spring (not shown in the figure) is fixedly installed, with the spring protruding from the countersunk hole. The pressure roller 6 has a third through hole along the axial direction, and the third rotating shaft 12 is installed in the third through hole through a bearing to ensure that the pressure roller 6 can rotate freely. Both ends of the third rotating shaft 12 protrude from the third through hole, and the protruding parts at both ends of the third rotating shaft 12 extend into the corresponding elongated through holes 11 and can slide along the length of the elongated through holes 11, ensuring that the third rotating shaft 12 is parallel to the first rotating shaft 4.

[0029] Furthermore, a limiting shaft (not shown in the figure) is provided at the notch position of the through hole 11 to prevent the third rotating shaft 12 from sliding out of the through hole 11.

[0030] like Figure 3 As shown, a limit block 13 is provided at a suitable position on the mounting base 1 to limit the rotation of the bracket 4.

[0031] When the support 4 is rotated, the pressure roller 6 interferes with the feed roller 2. At this time, the end of the pressure roller 6 will be higher than the end of the crossbar 7 of the support 4. Under the action of the gravity of the pressure roller 6, the surface of the pressure roller 6 contacts the surface of the feed roller 2. At the same time, under the action of the gravity of the pressure roller 6, the spring is slightly compressed. In this state, the feeding of the core wire is suitable for situations where the core wire tension requirement is relatively small. When the pressure roller 6 is rotated further, the feed roller 2 will squeeze the pressure roller 6, and then the pressure roller 6 will compress the spring through the third rotating shaft 12. The support 4 rotates until the end of the pressure roller 6 is lower than the end of the crossbar 7 of the support 4, and at the same time, the support 4 contacts the limiting block 13. Figure 4 As shown, at this time, under the action of the spring force, the surface of the pressure roller 6 is in close contact with the surface of the feed roller 2. In this state, the feeding of the core wire is suitable for situations where the core wire tension requirement is large.

[0032] In summary, the core thread feeding structure described in this embodiment of the invention uses a drive motor to drive the feeding roller, which works in conjunction with the pressure roller to achieve active feeding of the core thread. Simultaneously, it can be synchronized with the output motor on the spray gun to ensure consistent core thread tension. Furthermore, it can achieve core thread feeding with two different tension requirements, making it suitable for various 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.
