Description

Technical Field

[0001] This utility model relates to the field of pre-spinning treatment technology, and is mainly used to transport edge material or filament bundle to the next process, specifically to a feeding device. Background Technology

[0002] As is well known, in the process of yarn tow production, the yarn tow needs to undergo a series of complex processes after exiting the spinning box, including ring blowing, winding, drawing, and loading into drums. If the yarn feeding is not smooth during the spinning and drawing process, it will cause a series of problems such as yarn breakage and roller entanglement, directly affecting the quality of the raw yarn. Troubleshooting is time-consuming and labor-intensive, resulting in a huge waste of resources for production enterprises. In spinning production equipment, there are various structures used for yarn tow conveying, but current feeding devices generally suffer from narrow applicability, non-adjustable gaps, and feeding jams. Summary of the Invention

[0003] The purpose of this utility model is to address the problems in the related technologies by proposing a feeding device to overcome the aforementioned technical problems existing in the prior art.

[0004] The technical solution of this utility model is as follows: This utility model includes a support and a feeding unit. The feeding unit comprises a spring, a first connecting frame, a bearing, a first feeding roller, a sprocket, a second connecting frame, a pin, and a second feeding roller. The first feeding roller is fixedly mounted on the support at both ends via the bearing and the first connecting frame, and the sprocket is mounted on the shaft end of the first feeding roller. The second feeding roller is rotatably mounted on the support at both ends via the bearing, the second connecting frame, and the pin. One end of the spring is connected to the support, and the other end is pressed against the second connecting frame. A guide ring is installed on the support, and the guide ring is located above the feeding inlet between the first and second feeding rollers.

[0005] Feed roller two, centered on a pin, can swing to adjust the angle, thus changing the gap between feed roller one and feed roller two. A sprocket drives feed roller one to rotate, and the spring's counterforce presses feed roller two tightly against feed roller one. This allows feed roller two to rotate along with feed roller one, clamping and conveying the filaments or edge material passing through the guide ring downwards. The gap between feed roller one and feed roller two can automatically adjust according to the thickness of the filaments and edge material, adapting to various types and specifications of materials. The structure is simple and reliable, ensuring smooth conveying and improving product quality while saving costs.

[0006] The beneficial effects of this utility model are as follows: by adopting an active feeding method, it ensures smooth entry into the next process. It can be used to transport the filament to the next process, or to transport the remaining scrap to the screw extruder, thereby realizing waste utilization and saving costs.

[0012] like Figures 1 to 3 As shown, this utility model includes a bracket 1 and a feeding unit. The feeding unit comprises a spring 2, a connecting frame 3, a bearing 5, a feeding roller 6, a sprocket 7, a connecting frame 8, a pin 9, and a feeding roller 10. The feeding roller 6 is fixedly mounted on the bracket 1 at both ends via the bearing 5 and the connecting frame 3, respectively. The sprocket 7 is mounted on the shaft end of the feeding roller 6. The feeding roller 10 is rotatably mounted on the bracket 1 at both ends via the bearing 5, the connecting frame 8, and the pin 9, respectively. One end of the spring 2 is connected to the bracket 1, and the other end is pressed against the connecting frame 8. A guide ring 4 is mounted on the bracket 1, located above the feeding inlet between the feeding roller 6 and the feeding roller 10.

[0013] Feed roller 2 10 can swing around pin 9 to adjust the gap between feed roller 1 6 and feed roller 2 10. Sprocket 7 drives feed roller 1 6 to rotate, and the counterforce of spring 2 presses feed roller 2 10 tightly against feed roller 1 6. Thus, feed roller 2 10 rotates along with feed roller 1 6, clamping and conveying the filament or edge material passing through guide ring 4 downwards. The gap between feed roller 1 6 and feed roller 2 10 can automatically adjust according to the thickness of the filament and edge material, adapting to various types and specifications of materials. The structure is simple and reliable, ensuring smooth conveying, improving product quality, and saving costs.

[0014] The beneficial effects of this utility model are as follows: by adopting an active feeding method, it ensures smooth entry into the next process. It can be used to transport the filament to the next process, or to transport the remaining scrap to the screw extruder, thereby realizing waste utilization and saving costs.

[0015] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
