Description

Technical Field

[0001] The utility model relates to the technical field of draw frames, in particular to a draw frame for textile use. Background Technique

[0002] In the textile field, there are many heights of spinning cans adapted in the draw frame field, usually 1200 mm high, 1100 mm high, and 900 mm high. However, once a draw frame selects a certain specification, spinning cans of other specifications will not be applicable. Taking the equipment for outputting a 1200-high spinning can as an example, for a draw frame with a height of 1200 mm, if it directly spins into a 900-mm-high spinning can, there is a large drop in the middle and no spinning can to bear it. Due to the centrifugal force, the sliver spreads outwards and cannot be properly placed into the spinning can. Therefore, the spinning can must be very close to the upper coiler to correctly wind and place the sliver.

[0003] Normally, the distance between the spinning can of the draw frame and the upper coiler of the draw frame is very small, about 30 mm. When the gap between the upper part of the spinning can and the coiler disk is too large, it cannot be properly formed. However, due to the requirements of user workshop management or process adjustment, when a high spinning can needs to be replaced with a short spinning can, a conventional draw frame is not applicable and has low practicability. For this reason, we propose a draw frame for textile use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a draw frame for textile use to solve the problem that the distance between the spinning can of the draw frame and the upper coiler of the draw frame is very small, about 30 mm. When the gap between the upper part of the spinning can and the coiler disk is too large, it cannot be properly formed. However, due to the requirements of user workshop management or process adjustment, when a high spinning can needs to be replaced with a short spinning can, a conventional draw frame is not applicable.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A draw frame for textile use, comprising: a draw frame body and a tray, an empty cavity is opened inside the draw frame body;

[0006] A lifting assembly, the lifting assembly is arranged inside the draw frame body, the tray is fixedly installed on the top of the lifting assembly, and the lifting assembly drives the tray to lift, so that the spinning can on the top of the tray can be at an effective working distance.

[0007] Among them, at least two groups of the lifting assemblies are provided and arranged at equal intervals.

[0008] Among them, the lifting assembly includes a lower spiral surface cylinder body, a rotating shaft and a belt. The bottom of the lower spiral surface cylinder body is fixedly connected with a rotating wheel through the rotating shaft. The rotating wheel is rotatably installed inside the draw frame body. The two rotating wheels are rotationally connected through the belt. A motor is fixedly installed inside the draw frame body, and the output shaft of the motor is fixedly connected to the center of the bottom of one of the rotating wheels.

[0009] Among them, a connecting column is rotatably installed inside the lower spiral surface cylinder body.

[0022] Embodiment 1

[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: a drawframe for textile, including: a drawframe body 1 and a tray 3, and an empty cavity 4 is provided in the drawframe body 1;

[0024] A lifting assembly 2, the lifting assembly 2 is arranged inside the drawframe body 1, the tray 3 is fixedly installed on the top of the lifting assembly 2, and the lifting assembly 2 drives the tray 3 to lift, so that the spinning bobbin on the top of the tray 3 can be at an effective working distance;

[0025] At least two groups of lifting assemblies 2 are provided and arranged at equal intervals;

[0026] Equipped with a plurality of spinning bobbins and a lifting assembly 2, which can further improve the production efficiency of the drawframe.

[0027] The lifting assembly 2 includes a lower helical surface cylinder body 21, a rotating shaft 210 and a belt 28. The bottom of the lower helical surface cylinder body 21 is fixedly connected with a runner 27 through the rotating shaft 210. The runner 27 is rotatably installed in the drawframe body 1. The two runners 27 are rotationally connected through the belt 28. A motor 29 is fixedly installed in the drawframe body 1, and the output shaft of the motor 29 is fixedly connected to the center of the bottom of one of the runners 27;

[0028] By starting the motor 29, the motor 29 drives the runner 27 fixedly connected to its output shaft to rotate, and drives the other runner 27 to rotate through the belt 28, that is, drives the two lower helical surface cylinder bodies 21 fixedly connected to the runner 27 to rotate. Then, by installing one motor 29, the two lower helical surface cylinder bodies 21 can be driven to rotate, saving resources and reducing costs.

[0029] A connecting column 22 is rotatably installed in the lower helical surface cylinder body 21;

[0030] The lifting assembly 2 further includes an upper helical surface cylinder body 23. One side of the inner cavity of the upper helical surface cylinder body 23 is fixedly installed with a slider 24. A chute 25 for the slider 24 to slide is provided on the surface of the connecting column 22. The upper helical surface cylinder body 23 is slidably installed on the connecting column 22 by sliding the slider 24 in the chute 25;

[0031] The facing surfaces of the upper helical surface cylinder body 23 and the lower helical surface cylinder body 21 are mutually adapted helical surfaces and are mutually attached;

[0032] By starting the motor 29 to drive the lower helical surface cylinder body 21 to rotate, when the lower helical surface cylinder body 21 rotates, an upward acting force will be given to the upper helical surface cylinder body 23. Then, the upper helical surface cylinder body 23 slides upward on the connecting column 22 under the sliding fit of the slider 24 and the chute 25, that is, drives the tray 3 fixedly connected thereto to move upward. When the motor 29 drives the lower helical surface cylinder body 21 to rotate back, the upper helical surface cylinder body 23 will slide down on the connecting column 22 under the action of gravity, so as to adjust the distance between the spinning tube and the upper coiler of the drawing frame body 1, so that the spinning tube can be at an effective working distance. One drawing frame can be applicable to spinning tubes of different heights, which can increase the applicable range of the drawing frame and reduce the textile cost.
