[0002] The spinning frame is a link in the entire textile process. Its task is to process the coarse yarn spun by the roving frame into fine yarn. That is, during the processing process, the drafting device in the spinning frame must provide sufficient drafting force to make the yarn slivers more uniform.

[0003] For example, the authorization announcement number "CN204661900U" is named a spinning frame drafting mechanism, which can freely adjust the gap between the upper and lower parts of the leather roller and the roller to solve the problem of loose fit between the two due to the long-term use of the leather ring, thereby extending the service life of the leather ring. It has a simple structure and is easy to produce. However, the existing spinning frame drafting mechanism and the spinning frames of linen textile enterprises mostly remain at the level of the 1990s. The drafting mechanism uses copper tiles, the equipment load is large, the transmission is unstable, and the feed roller shaft and the intermediate roller shaft are jumping, which affects the yarn quality.

[0007] Preferably, the middle section of the lower end of the flax fine sand body is movably connected to an intermediate roller, and one side of the intermediate roller is rotatably connected to a deadweight roller through a belt.

[0008] Preferably, a drafting roller is movably connected to the outer side of the lower end of the flax fine sand body, and a drafting and pressing roller is relatively provided above the drafting roller.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] See also Figure 1-6: In this embodiment, a spinning frame drafting mechanism includes a water trough 1, a rotating guide roller 2 and a linen yarn main body 4. The rotating guide roller 2 is rotatably installed on the inner side of the water trough 1, and the linen yarn main body 4 is movably connected to the outer side of the rotating guide roller 2. The upper outer side of the linen yarn main body 4 is movably connected with a yarn drawer 5. The spinning frame is first used for the spinning processing operation. First, the boiled coarse yarn passes through the guide wheel 12, bypasses the rotating guide rod 2 in the water trough 1, passes through the edge of the water trough 1 and enters the feeding yarn drawer 5, and enters the drafting mechanism. First, it passes between the feeding pressure roller 6 and the feeding roller 7. The lower end of the yarn drawer 5 is provided with a feeding roller 7, and the upper part of the feeding roller 7 is provided with a feeding pressure roller 6.

[0022] The middle section of the lower end of the flax yarn main body 4 is movably connected to an intermediate roller 9, and one side of the intermediate roller 9 is rotatably connected to a deadweight roller 8 through a belt.

[0023] A drafting roller 10 is movably connected to the outer side of the lower end of the flax yarn body 4, and a drafting and pressing roller 11 is relatively provided above the drafting roller 10.

[0024] Needle roller bearings 3 are rotatably connected to the outer shafts of the drafting roller 10, the intermediate roller 9 and the feed roller 7. The drafting roller shafts of the linen spinning frame are changed from the original copper washers to needle roller bearings 3. The needle roller bearings 3 are used to reduce the load on the equipment, ensure smooth transmission, and reduce the vibration of the feed roller shaft and the intermediate roller shaft. This is beneficial to the quality of the yarn, especially the effect on the yarn. The key components of the linen spinning frame are redesigned, the structure is optimized, and the stability and durability of the equipment are improved.

[0025] The uppermost end of the flax yarn body 4 is connected to a guide wheel 12 which is rotated around the rotating guide roller 2. The guide wheel 12 is used to guide the wound roving into the water tank 2 for soaking. The other side of the guide wheel 12 is arranged opposite to the line roller around which the flax yarn body 4 is wound.

[0026] Working principle:

[0027] The spinning frame drafting mechanism is used to process the spun yarn through the spinning frame. First, the boiled roving passes through the guide wheel 12, bypasses the rotating guide rod 2 in the water tank 1, passes through the edge of the water tank 1 and enters the feeding yarn guide 5, and enters the drafting mechanism. First, it passes between the feeding pressure roller 6 and the feeding roller 7, enters the apron, and then enters the drafting pressure roller 11 and the drafting roller 10. The roving is drafted and thinned. The yarn drawn out by the drafting roller 10 passes through the guide plate (leaf plate) and then led to the steel ring and steel ring ring (nylon hook). It is lifted up and down by the lifting system, thereby obtaining the twist of the yarn to form spun yarn, which is wound on the spun yarn tube on the rotating spindle. According to the setting of the yarn diameter, the roving is repeatedly wound on the spun yarn tube, completing the overall process of spinning roving into spun yarn.

[0028] Needle roller bearings 3 are rotatably connected to the outer shafts of the drafting roller 10, the intermediate roller 9 and the feed roller 7. The drafting roller shafts of the linen spinning frame are changed from the original copper washers to needle roller bearings 3. The needle roller bearings 3 are used to reduce the load on the equipment, ensure smooth transmission, and reduce the vibration of the feed roller shaft and the intermediate roller shaft. This is beneficial to the quality of the yarn, especially the effect on the yarn. The key components of the linen spinning frame are redesigned, the structure is optimized, and the stability and durability of the equipment are improved.

[0029] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
