Description

Technical Field

[0001] This utility model relates to the field of yarn bobbin finding technology, and in particular to a yarn bobbin finding device for machine. Background Technology

[0002] Existing yarn-finding devices locate the yarn end in the bobbin, cut it, and then place the yarn end into the bobbin using an upward airflow and downward suction method. Because the diameter of the guide tube inside the bobbin is relatively large, while the yarn end is thin, a large airflow is required to guide the yarn end. However, excessive airflow makes it impossible to precisely control the final position of the yarn end inside the bobbin, causing the yarn end to pass through the bobbin and be sucked under the tray, resulting in the belt winding back and affecting machine efficiency. Therefore, a solution is urgently needed.

[0017] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0018] Example

[0019] See Figure 1-2As shown: This utility model provides a yarn head finding device for a machine, including: yarn tube 11, yarn tube seat 13 and guide assembly.

[0020] In practical applications, the yarn tube 11 is used to wind the yarn. After the yarn is wound to a certain extent, it is cut off, resulting in a yarn head to be inserted into the yarn tube 11. The bottom of the yarn tube 11 is connected to the yarn tube seat 13, and the yarn tube 11 is provided with a channel 12 for the yarn head to pass through.

[0021] One end of the channel 12 is connected to the top end of the yarn tube 11, and the other end is connected to the bottom end of the yarn tube seat 13. The guide assembly is connected to the air pump, and the top end of the guide assembly is inserted into the yarn tube seat 13, forming an airflow at the bottom end of the yarn tube seat 13 to guide the yarn head to pass through the channel 12 along the top end of the yarn tube 11.

[0022] The guiding assembly mainly consists of a base 21, a guide tube 22, and a guide section.

[0023] In practical applications, the top of the guide tube 22 and the bottom of the channel 12 are inserted into each other, and the bottom of the guide tube 22 is connected to the base 21. The guide tube 22 contains an airflow channel 221; the airflow channel 221 is a tapered channel that narrows from top to bottom along the vertical direction of the guide tube 22. This causes the diameter of the bottom of the channel 12 to change after the guide tube 22 is inserted into the channel 12 along the bottom of the yarn tube seat 13, thereby reducing the internal space of the channel 12.

[0024] The air inlet of the guide section is connected to the air pump, and the air outlet is connected to the airflow channel 221. The airflow at the outlet is transported along the inner wall of the airflow channel 221 to the bottom of the airflow channel 221. With this configuration, when the guide section transports airflow to the bottom of the airflow channel 221, the airflow generates suction at the moment it exits the bottom of the airflow channel 221, thereby drawing the yarn end at the top of the channel 12 into the channel 12. Moreover, since the airflow channel 221 is cone-shaped, suction can be generated without a large airflow, and the range of airflow delivery rate adjustment is also greater.

[0025] The flow guide section mainly consists of a first air guide tube 211 and a second air guide tube.

[0026] The first air guide pipe 211 is connected to one side of the base 21, and the air outlet of the first air guide pipe 211 is connected to the side wall of the airflow channel 221, and the air outlet of the first air guide pipe 211 is directed towards the bottom of the airflow channel 221; the air inlet of the first air guide pipe 211 is connected to the air outlet of the air pump.

[0027] The second air guide tube is connected to the other side of the base 21, and the air outlet of the second air guide tube is connected to the side wall of the airflow channel 221, and the air outlet of the second air guide tube is directed towards the bottom of the airflow channel 221; the air inlet of the second air guide tube is connected to the air outlet of the air pump.

[0028] It also includes a regulating valve, which is installed on the air outlet pipe of the air pump to regulate the airflow in the air outlet pipe. By setting the regulating valve, in conjunction with the first air guide pipe 211 and the second air guide pipe, the airflow in the airflow channel 221 is changed. At the same time, since the airflow flows along the side wall of the airflow channel 221 towards the bottom of the airflow channel 221, suction is generated, which draws the yarn end into the channel 12 along the top of the yarn tube 11.

[0029] 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.
