Detailed Description

The following describes in further detail embodiments of the present invention.

As shown in fig. 1 to 5, the utility model discloses a doffing tube device with self-cleaning function, which comprises a yarn outlet 1, a yarn guide 2, a cleaner 3, a sealing ring 4 and a doffing tube 5 a. The cleaning function can be realized only by introducing high-pressure air into the wire guide 2 through the cleaner 3, and a person skilled in the art can design many similar structures according to the idea of the invention on the basis of not paying creative labor.

In order to make the most use of the existing product structure and to take into account the ease of processing and assembly. In this embodiment, the following structure is adopted: the yarn withdrawal tube 5a comprises a yarn withdrawal tube binder 5 and a twist blocker 5 b. Wherein, the thread guide 2 comprises two sections: the combined part 21 comprises a cylindrical surface 2a and a thread guide limiting surface 2b, and the stepped part 22 is provided with an air outlet 2 c. The thread guide 2 is fitted in the cleaner 3, and the coupling portion 21 is press-fitted to the cleaner 3. The cylindrical surface 2a of the thread guide 2 and the cylindrical hole 3c of the cleaner are tightly pressed together, the thread guide limiting surface 2b and the cleaner limiting surface 3b are used for preventing the air outlet 2c from being reversely assembled, and the thread guide limiting surface 2b and the cleaner limiting surface are fixed on the yarn outlet 1 together after being pressed and assembled. In order to reduce the pressure loss of the high-speed airflow for cleaning, the axis of the air outlet 2c and the axis of the yarn guide 2 form a certain included angle in the range of 5-60 degrees, and the included angle of 45 degrees is adopted in the embodiment. The yarn guide tube binder 5 is embedded at the other end of the cleaner 3 and is sealed by a sealing ring 4 arranged at a sealing groove 3d to prevent air leakage, and an inlet air 3a on the cleaner 3 is connected with an external high-speed air source.

The utility model discloses a theory of operation:

in the normal spinning process, the air inlet 3a of the cleaner 3 and an external high-speed air source are in a blocking state through program control, so that the spinning tightness in the doffing tube is ensured. When the yarn is broken, the program detects a yarn breaking signal, an external high-speed air source connected with the yarn breaking signal is automatically opened according to the program setting, high-speed air flow enters the cleaner 3 through the air inlet 3a, enters the yarn guide tube combining piece along the air outlet 2c on the yarn guide 2, performs dust cleaning on the position of the twist blocker 5b, and brings out the yarn guide tube combining piece. After the cleaning action is finished, the program automatically controls and blocks the connection between the air inlet and an external high-speed air source, and the sealing requirement of spinning is ensured.

When the equipment is maintained, the equipment control interface is provided with a whole machine yarn guide tube automatic cleaning button, after clicking, the equipment automatically executes the dust cleaning operation of each spindle of yarn guide tube in sequence according to the program setting, the maintenance workload of people is reduced, and the production efficiency is improved.

The utility model has the advantages of, directly borrow current doffing tube binder, through the seal wire ware, cleaner and the sealing washer that increase, can also carry out self-cleaning through procedure automated control, regularly hinder in the doffing tube binder to twist with the fingers the ware, prevent that the dust from gathering, avoided gathering the influence that brings because of the dust connects quality and finished yarn quality difference, owing to hinder the use of twisting the ware, guaranteed the higher fracture brute force of yarn simultaneously to ensure customer's economic benefits.

The above embodiment is only one embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
