[0022] Please refer to Figure 1 、 Figure 2 and Figure 3 . An embodiment provided by the present utility model: a yarn supply device for a roving frame;

[0023] It includes a base 1 and a first yarn supply assembly 2. The first yarn supply assembly 2 is installed on the top of the base 1. The first yarn supply assembly 2 includes a bottom mounting shell 3. A first limiting assembly 7 is installed on the front of the bottom mounting shell 3. A second yarn supply assembly 20 is installed on the top of the first yarn supply assembly 2. The second yarn supply assembly 20 includes a top mounting shell 21, and the top mounting shell 21 is fixed on the top of the bottom mounting shell 3. A second limiting assembly 23 is installed on the front of the top mounting shell 21. A first rotating shaft 4 is rotatably installed inside the bottom mounting shell 3, and the connecting end of the first rotating shaft 4 penetrates through both sides of the bottom mounting shell 3. One end of the first rotating shaft 4 is connected to a connecting sleeve 5, and a fixing rod 6 is installed through the top of the connecting sleeve 5;

[0024] The base 1 provides an installation position for the first wire feeding assembly 2 at the top, enabling the first wire feeding assembly 2 to be installed and used. When the first wire feeding assembly 2 is in use, the outer side of the first rotating shaft 4 is wound with the yarn to be fed. The first wire feeding assembly 2 and the second wire feeding assembly 20 have the same function, so that the wire feeding device has two wire feeding assemblies. When the yarn in the first wire feeding assembly 2 is used up, then the second wire feeding assembly 20 is used for wire feeding immediately. Then, the used first wire feeding assembly 2 rotates the first rotating shaft 4 under the action of the first driving assembly 13 to wind the new yarn on the outer side of the first rotating shaft 4 for the next use, thereby improving the wire feeding efficiency of the wire feeding device. The connecting sleeve 5 is used to connect with the rotating rod 18 and is then fixed by the fixing rod 6, so that the rotating end of the driving motor 17 can be connected with the first rotating shaft 4 to drive the first rotating shaft 4 to rotate.

[0025] Please refer to Figure 1 and Figure 4 , an embodiment provided by the present utility model: a wire feeding device for a roving frame;

[0026] It includes an installation frame 8 and an installation plate 14. The first limiting assembly 7 includes the installation frame 8. A first sliding groove 9 is opened at the top of the installation frame 8. A slider 10 is installed at the top of the first sliding groove 9. A connecting rod 11 is installed at the top of the slider 10. A limiting frame 12 is installed at the top end of the connecting rod 11. A first driving assembly 13 is installed on one side of the bottom installation shell 3. The first driving assembly 13 includes an installation plate 14, a second sliding groove 15, a sliding seat 16 and a driving motor 17. The second sliding groove 15 is opened at the top of the installation plate 14. A sliding seat 16 is slidably installed at the top of the installation plate 14. A driving motor 17 is installed at the top of the sliding seat 16. The output end of the driving motor 17 is installed with a rotating rod 18, and the rotating rod 18 corresponds to the connecting sleeve 5. A through hole 19 is opened through the top of the rotating rod 18;

[0027] The mounting bracket 8 provides a position for the opening of the first chute 9. The first chute 9 provides a space for the sliding of the slider 10. The slider 10 provides a mounting position for the connecting rod 11. The connecting rod 11 enables the limiting frame 12 to be installed and used. When the yarn is supplied on the first rotating shaft 4 and the second rotating shaft 22, it needs to pass through the limiting frame 12 slidably mounted on the first limiting component 7 and the second limiting component 23. The yarn is limited through the limiting frame 12, making the yarn supply more stable. At the same time, the limiting frame 12 can slide without affecting the yarn supply. The sliding seat 16 can slide on the top of the mounting plate 14, so that the driving motor 17 mounted on the top can slide. When it is necessary to rotate the first rotating shaft 4 or the second rotating shaft 22, through the sliding of the driving motor 17, the rotating rod 18 mounted on the output end of the driving motor 17 is inserted into the connecting sleeve 5 and fixed through the fixing rod 6, so that the driving motor 17 can drive the first rotating shaft 4 or the second rotating shaft 22 to rotate, making it more convenient to wind the yarn on the first rotating shaft 4 and the second rotating shaft 22, thereby improving the threading efficiency of the yarn supply device.

[0028] Please refer to Figure 1 , an embodiment provided by the present utility model: a yarn supply device for a roving frame;

[0029] It includes a second driving component 24. The second rotating shaft 22 is rotatably mounted inside the top mounting shell 21. The second rotating shaft 22 has the same structure as the first rotating shaft 4. A second driving component 24 is mounted on one side of the top mounting shell 21, and the second driving component 24 has the same structure as the first driving component 13;

[0030] The second driving component 24 and the second rotating shaft 22 respectively have the same functions as the first driving component 13 and the first rotating shaft 4, so that there are two sets of yarn supply components in the device, thereby improving the yarn supply efficiency.

[0031] Working principle: Before using the yarn supply device for the roving frame, it should be checked first whether there are any problems affecting the use of the yarn supply device for the roving frame. First, place the yarn supply device at the position where it needs to be used through the base 1. The first rotating shaft 4 and the second rotating shaft 22 are both wound with yarn. The yarn on the yarn supply device is transmitted through the transmission device. If the yarn on the first rotating shaft 4 is used up, the yarn on the second rotating shaft 22 can be transmitted immediately. By sliding the sliding seat 16, the rotating rod 18 at the output end of the driving motor 17 is inserted into the connecting sleeve 5 and fixed, so that the first rotating shaft 4 rotates, making it faster to wind the yarn on the first rotating shaft 4.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model, and any reference signs in the claims should not be regarded as limiting the claims involved.
