Description

Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to a spinning cradle. Background Art

[0002] Spinning frame is a spinning machine that stretches, twists and winds semi-finished roving or slivers into spun yarn during the spinning process. The slivers are stretched and twisted on the roving frame to make roving, the combing machine combs the fibers to make combed slivers, the needle carding machine combines the slivers, and the needle row stretches to improve the sliver structure. The roving is further twisted and spun into spun yarn on the ring spinning frame. The spinning frame is the main machine for spinning.

[0003] However, during the use of the cradles of the existing spinning machines in textile factories, there are usually multiple groups of cradles arranged in a row, and each group of cradles is provided with three pressure rollers, corresponding to the front, middle and rear rollers respectively. Before the equipment is used, the pressure of the rollers needs to be adjusted through the cradles, and then the cradles are pressed by springs so that there is a certain pressure between the pressure rollers and the rollers to ensure that the lines between the pressure rollers and the rollers can be continuously drafted. However, since there is a certain instability in applying pressure to the cradles by the elastic force of the springs, when the equipment is in operation, due to the certain vibration of the equipment itself, the lines between the pressure rollers and the rollers cannot maintain a constant pressure, and relative sliding between the drafted lines and the pressure rollers is likely to occur, resulting in poor drafting effect.

[0004] In addition, in the process of guiding the wire to be stretched, the existing cradle usually introduces the wire from one side of the cradle to between the pressure roller and the roller, which easily causes the wires between adjacent cradles to be entangled with each other, affecting the stretching work.

[0005] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0006] The purpose of the utility model is to provide a spun yarn cradle to solve the problem proposed in the above background technology that the existing cradle uses the elastic force of the spring to apply pressure to the cradle, which may cause certain instability. When the equipment is in operation, due to certain vibrations of the equipment itself, the lines between the pressure roller and the roller cannot maintain a constant pressure, and relative sliding between the stretched lines and the pressure roller is likely to occur, resulting in poor stretching effect. In addition, in the process of guiding the stretched lines by the existing cradle, the lines are usually introduced from one side of the cradle to between the pressure roller and the roller, which may easily cause the lines between adjacent cradles to become entangled with each other, affecting the stretching work.

[0027] One end of the insertion shaft located outside the sleeve is fixedly connected with a pulling plate for adjusting the position of the insertion shaft.

[0028] Furthermore, the lead assembly includes:

[0029] The first threading holes are provided in multiple groups and are arranged along the rotating rod from top to bottom to limit the thread;

[0040] 2. The utility model drives the locking block into the groove when the pressure roller presses the line onto the roller, and the through hole and the insertion hole are on the same axis, and then pushes the pull plate, which drives the insertion shaft to move along the through hole, so that one end of the insertion shaft is inserted into the insertion hole, completing the positioning of the locking block, thereby ensuring that a stable pressure is always maintained between the pressure roller and the roller, avoiding unstable pressure between the pressure roller and the roller due to the vibration of the equipment itself, resulting in relative sliding between the stretched line and the pressure roller.

[0076] Furthermore, the driving unit 3 includes:

[0077] A driving motor 31 is mounted on the upper end of the base 100;

[0078] The rollers 32 are provided with three groups, one of which is connected to the driving end of the driving motor 31, and the other two groups are sequentially connected through belts 33. The rollers 32 correspond to the pressure rollers 115 one by one.

[0079] The third bracket 34 is fixedly mounted on the upper end of the base 100 to support the roller 32 .

[0080] It should be noted that: in the specific implementation process of the utility model, initially, the pressure roller 115 and the roller 32 are in a separated state, and the line 122 is passed through the first threading hole 1111, the second threading hole 1211, and the third threading hole 1231 in sequence, and then the pull block 112 is pressed downward, and the pull block 112 drives the rotating rod 111 to rotate along the first bracket 101, and the rotating rod 111 drives the pressure roller 115 to move downward through the extension rod 114, so that the pressure roller 115 is pressed on the upper end of the roller 32. At this time, the line 122 originally located directly below the pressure roller 115 is pressed between the pressure roller 115 and the roller 32, and the driving motor 31 is started. The driving motor 31 drives the roller 32 to rotate. The roller 32 drives the pressure roller 115 to rotate synchronously under the friction between the pressure roller 115, so that the line 122 located between the pressure roller 115 and the roller 32 is synchronously stretched;

[0081] In the entire drafting process, the lines 122 of the utility model are guided separately by guiding the two groups of lines 122 corresponding to each rotating rod 111 along the first threading hole 1111 provided in the rotating rod 111, the second threading hole 1211 provided at the lower part of the rotating rod 111, and the third threading holes 1231 located on both sides of the positioning unit 2, so as to ensure that the two groups of lines 122 will not be entangled with each other, and ensure that the drafting process can be carried out continuously;

[0082] When the pressure roller 115 of the utility model presses the line 122 onto the roller 32, the rotating rod 111 drives the locking block 113 to enter the groove 211, and at this time the through hole 212 and the insertion hole 1131 are on the same axis, and then the pulling plate 232 is pushed, and the pulling plate 232 drives the insertion shaft 23 to move along the through hole 212, so that one end of the insertion shaft 23 is inserted into the insertion hole 1131, completing the positioning of the locking block 113, thereby ensuring that a stable pressure is always maintained between the pressure roller 115 and the roller 32, avoiding the unstable pressure between the pressure roller 115 and the roller 32 due to the vibration of the equipment itself, resulting in relative sliding between the stretched line 122 and the pressure roller 115.
