Description

Technical Field

[0001] The utility model relates to a ring spinning frame, in particular to a waste yarn cleaning device for the spindle of a ring spinning frame. Background Art

[0002] The spindles of the ring spinning frame are evenly and juxtaposedly installed on the dragon tendon of the ring spinning frame. When the ring spinning frame needs to do doffing after completing a spinning cycle, before the automatic yarn cutting link, a section of safety yarn needs to be left on the spindle to prepare for the automatic joint of the next spinning cycle. After the new spinning cycle spins normally, the safety yarn becomes waste yarn. Each time a spinning cycle is completed, the waste yarn accumulates on the spindle once. As the waste yarn increases continuously, the head retention rate will be greatly reduced, and the yarn forming quality will also deteriorate. Therefore, the waste yarn wound on the spindle must be cleaned regularly.

[0003] A waste yarn cleaning device for a ring spinning frame with the patent number 201120473892.9 discloses a waste yarn cleaning device fixedly installed on the dragon tendon. The cutting blades correspond to the spindles one by one for waste yarn cleaning. A new type of waste yarn cleaning device for a ring spinning frame with the patent number 201220195453.0 also discloses a waste yarn cleaning device fixedly installed on the dragon tendon. The friction parts correspond to the spindles one by one for waste yarn cleaning. These two waste yarn cleaning devices have the following two deficiencies in actual use: one is that the usage quantity and spare quantity of the cutting blades or friction parts are huge, and the usage cost and replacement cost are high; the other is that if it is found during the waste yarn cleaning that a certain cutting blade or friction part is worn and cannot be used, the waste yarn cleaning of the corresponding spindle cannot be carried out in real time, which affects the normal yarn cleaning and spinning work. Summary of the Invention

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and provide a waste yarn cleaning device for the spindle of a ring spinning frame, which has a simple and novel structure, practical functions, can clean the yarn in a one-to-many mobile manner, has a low usage cost, and can clean the yarn in real time and cleanly.

[0005] The technical scheme adopted by the utility model is: a waste yarn cleaning device for the spindle of a ring spinning frame, which includes a linear guide rail, a lower mounting plate, an upper mounting plate and a yarn cleaning blade. The slide rail of the linear guide rail is fixedly installed on the dragon tendon. The lower mounting plate is fixedly connected with the slider of the linear guide rail. The upper mounting plate includes a vertical plate, a flat plate and an inclined plate. The upper mounting plate is arranged above the lower mounting plate. The lower end of the inclined plate is hinged to the lower mounting plate through a hinge. A compression spring is arranged between the inclined plate and the lower mounting plate. A plurality of yarn cleaning blades are juxtaposedly installed on the vertical plate. The shape of the yarn cleaning blade is "U" shaped, and includes a middle plate and two side plates. The yarn cleaning blade is fixedly connected with the vertical plate through the middle plate. Blades are provided on the two side plates and are in contact with the spindle.

[0006] The utility model has the following beneficial effects compared with the prior art: simple and novel structure, practical function, capable of one-to-many mobile yarn cleaning, low use cost, and real-time and clean yarn cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 is a schematic structural diagram of the utility model,

[0008] Figure 2 is Figure 1 the left view of

[0009] Figure 3 is Figure 1 the top view of DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The following is a detailed description of the preferred embodiments of the utility model with reference to the accompanying drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the utility model.

[0011] As Figure 1 , Figure 2 and Figure 3 shown, a waste yarn cleaning device for the spindle of a ring spinning frame includes a linear guide rail 1, a lower mounting plate 2, an upper mounting plate 3 and a yarn cleaning blade 4. The linear guide rail 1 includes a slide rail and a slider, and the slider slides linearly on the slide rail. The slide rail of the linear guide rail 1 is fixedly installed on the dragon tendon. The lower mounting plate 2 is fixedly connected to the slider of the linear guide rail 1. The upper mounting plate 3 includes a vertical plate 31, a flat plate 32 and an inclined plate 33. The upper mounting plate 3 is arranged above the lower mounting plate 2. The lower end of the inclined plate 33 is hinged to the lower mounting plate 2 through a hinge 5. A compression spring 6 is arranged between the inclined plate 33 and the lower mounting plate 2. Three yarn cleaning blades 4 are arranged side by side on the vertical plate 31. The shape of the yarn cleaning blade 4 is "U", including a middle plate and two side plates. The yarn cleaning blade 4 is fixedly connected to the vertical plate 31 through the middle plate. Knife edges are provided on the two side plates and are in contact with the spindle.

[0012] The lower mounting plate 2 and the upper mounting plate 3 can move back and forth on the linear guide rail 1. The upper mounting plate 3 can rotate around the hinge 5. Press the flat plate 32 to compress the compression spring 6, and the yarn cleaning blade 4 moves away from the spindle. Release the flat plate 32, and under the rebound action of the compression spring 6, the yarn cleaning blade 4 comes into contact with the spindle to clean the waste yarn on the spindle. Knife edges are provided on both side plates of the yarn cleaning blade 4, and the two knife edges clean the waste yarn on the spindle, with high-efficiency, rapid and clean cleaning.

[0013] Press the flat plate 32 and move the upper mounting plate 3 to move the yarn clearing blade 4 away from the spindle rod and move it. When the yarn clearing blade 4 moves to the position corresponding to other spindle rods, release the flat plate 32 to make the yarn clearing blade 4 contact with the spindle rod under the pressure of the compression spring 6 to clean the waste yarn. Repeat the above operation to realize one-to-many mobile yarn clearing with low cost and real-time clean yarn clearing.

[0014] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope defined in the claims.
