Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment, and in particular relates to an active rotating steel ring group and a rotating method. Background Art

[0002] The steel ring is a steel ring-shaped component that plays a twisting and winding role in textile machinery such as ring spinning machines and ring twisting machines.

[0003] The "ring" of the ring spindle refers to the steel collar. Figure 1 As shown, the wire ring 8 on the one-piece steel collar 1 on the frame 7 is sleeved on the raceway groove of the one-piece steel collar 1. During spinning, the bobbin 9 drives the wire ring to rotate on the raceway groove. When the wire ring 8 rotates one circle, the yarn is twisted. The wire ring 8 is generally a small circle with a notch bent by steel wire. When it rotates on the steel collar, it slides closely on the inner side of the steel collar raceway due to the action of centrifugal force.

[0004] The relative speed between the wire ring and the connected steel collar is very high, which will cause wear and high temperature (above 300°C) due to friction, causing the wire ring to fly off, burn or rotate unsteadily, resulting in yarn breakage.

[0005] Therefore, it is necessary to propose a combination of steel collar and wire ring that can adapt to high-speed operation with less breakage and extend the service life of the steel collar, which is a problem that needs to be solved at present. Summary of the invention

[0006] In order to solve the problems in the related art, the present application provides an active rotating steel ring group and a rotating method, which solves the defects mentioned in the background technology.

[0007] The technical solution is as follows:

[0008] An active rotary steel collar group is assembled on a textile equipment, comprising: a frame, which is arranged on the textile equipment, and a plurality of through holes are penetrated on the frame, each of which is equipped with a conjoined steel collar; a runway groove is opened inside the conjoined steel collar; a wire ring is mounted on the runway groove of the conjoined steel collar; a rotating assembly is assembled between the inner wall of the through hole and the outer wall of the conjoined steel collar; a driving assembly, including a main driving member and a slave driving member installed on the frame; an annular transmission belt wound around the main driving member, all the conjoined steel collars, and the slave driving member; the main driving member is connected to an external power source; the annular transmission belt on the driving assembly drives the conjoined steel collar, which rotates with the cooperation of the rotating assembly, thereby reducing the relative movement speed and relative friction between the wire ring and the conjoined steel collar in the working state.

[0009] In a further embodiment, the rotating assembly is a thin-walled bearing assembled between the inner wall of the through hole and the outer wall of the one-piece steel collar.

[0010] In a further embodiment, the main driving member is a pulley installed on one side of the frame, and the pulley is connected to the external power source.

[0011] In a further embodiment, the external power source is an electric motor; and the endless transmission belt is an endless spindle belt.

[0012] In a further embodiment, a through slot is provided on one side of the frame, and a tensioning moving wheel is installed on the through slot by bolts; the annular spindle belt passes around and is transmission-connected to the tensioning moving wheel.

[0013] In a further embodiment, a tensioning wheel is installed on the frame on one side of the one-piece steel collar, and the tensioning wheel corresponds to the one-piece steel collar one by one; the annular spindle belt passes around and transmission-connects the one-piece steel collar and the tensioning wheel in sequence.

[0014] The present invention also provides an active rotation method, which is implemented based on the above-mentioned active rotation ring group, and the steps are as follows:

[0015] Step 1), when the textile equipment is spinning, the yarn is wound around the bobbin, driving the wire ring to rotate on the track groove of the conjoined steel collar;

[0016] Step 2), the motor drives the pulley to rotate, drives the pulley to rotate, drives the annular spindle belt to rotate under the rotation of the pulley, and the annular spindle belt drives the conjoined steel ring to rotate, so that the conjoined steel ring and the bobbin rotate in the same direction;

[0017] Step 3), when the textile equipment is running, the yarn tube is driven to rotate, the motor drives the pulley to rotate, the pulley drives the annular spindle belt to drive the one-piece steel collar to rotate, and the rotation speed of the one-piece steel collar can be controlled according to the change of yarn tension; the direction of rotation of the one-piece steel collar is consistent with the direction of rotation of the steel wire ring on the runway groove of the one-piece steel collar, at this time, the relative linear speed between the one-piece steel collar and the steel wire ring is reduced, thereby reducing the friction between the steel wire ring and the one-piece steel collar.

[0018] In a further embodiment, the yarn tension distribution law is:

[0019] T W >T O >T R >T S

[0020] Among them, T W is the winding tension, T O is the tension at the top of the balloon (where the wire ring hooks the yarn guide), T R is the tension at the bottom of the balloon (wire ring), T S is the spinning section tension;

[0021] The expression of the tension at the bottom of the balloon is:

[0022]

[0023] Where G is the weight of the wire ring; n is the spindle speed, 1000r / min; R is the radius of the one-piece steel collar, in cm; f is the "wedge friction coefficient" between the wire ring and the one-piece steel collar; is the yarn winding angle; θn is the direction angle of the reaction force of the conjoined steel collar on the wire ring; α R is the bottom angle of the balloon; K is the tension ratio, K = T W / T R .

[0024] By adopting the above technical solution, compared with the prior art, the beneficial effects of the technology of this patent are:

[0025] The present invention reduces the friction of the wire ring when it rotates on the runway groove, thereby avoiding wear and high temperature caused by friction, and avoiding the wire ring from flying off, burning or unstable rotation, which leads to yarn breakage. At the same time, the present invention can increase the movement speed of the wire ring, thereby increasing the spindle speed and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example 1

[0036] like Figure 2-3 As shown, an active rotary steel ring group is assembled on a textile device, and comprises a frame 7, and the frame 7 is arranged on the textile device. Generally, the textile device refers to textile machinery such as a ring spinning frame and a ring twisting frame.

[0037] The frame 7 is provided with a plurality of through holes, each of which is provided with a one-piece steel collar 1. A raceway groove is provided inside the one-piece steel collar 1. The wire ring 8 is sleeved on the raceway groove of the one-piece steel collar 1. The above structure is an existing structure and is installed on an existing textile equipment. Its structure and principle have been introduced in the background technology.

[0038] The rotating assembly is assembled between the inner wall of the through hole and the outer wall of the one-piece steel ring 1. The best choice of the rotating assembly is a thin-walled bearing 2 assembled between the inner wall of the through hole and the outer wall of the one-piece steel ring 1.

[0039] In order to realize the rotation of the conjoined steel collar 1, a driving assembly is designed on the frame 7 to drive the conjoined steel collar 1 to rotate, so as to realize the same-direction rotation of the conjoined steel collar 1 and the wire ring 8. The driving assembly includes a main driving member and a slave driving member installed on the frame 7, and an annular transmission belt wound around the main driving member, all the conjoined steel collars 1, and the slave driving member, and the main driving member is connected to an external power source. Specifically, the external power source uses a motor, and the annular transmission belt uses an annular spindle belt 6. The main driving member is a pulley 4 installed on one side of the frame 7, and the pulley 4 is connected to the motor.

[0040] In order to ensure the tension of the annular ingot band 6, a through slot is provided on one side of the frame 7, and a tensioning moving wheel 5 is installed on the through slot by bolts, and the annular ingot band 6 passes through and is connected to the tensioning moving wheel 5. A tensioning wheel 3 is installed on the frame 7 on one side of the conjoined steel ring 1, and the tensioning wheel 3 corresponds to the conjoined steel ring 1 one by one. The annular ingot band 6 passes through and is connected to the conjoined steel ring 1 and the tensioning wheel 3 in turn.

[0041] Example 2

[0042] An active rotation method is implemented based on an active rotating ring group in Example 1, and the steps are as follows:

[0043] Step 1), when the textile equipment is spinning, the yarn is wound around the bobbin 9, driving the wire ring 8 to rotate on the track groove of the conjoined steel collar 1;

[0044] Step 2, the motor drives the pulley 4 to rotate, the pulley 4 rotates, the annular spindle belt 6 is driven to rotate, and the annular spindle belt 6 drives the conjoined steel ring 1 to rotate, so that the conjoined steel ring 1 and the bobbin 9 rotate in the same direction;

[0045] Step 3: When the textile equipment is running, the bobbin 9 is driven to rotate, and the motor drives the pulley 4 to rotate. The pulley 4 drives the annular spindle belt 6 to drive the one-piece steel collar 1 to rotate, and the rotation speed of the one-piece steel collar can be controlled according to the change of the yarn tension. The direction of rotation of the one-piece steel collar is consistent with the direction of the wire ring 8 on the runway groove of the one-piece steel collar 1; at this time, the relative linear speed between the one-piece steel collar 1 and the wire ring 8 is reduced, thereby reducing the friction between the wire ring 8 and the one-piece steel collar 1.

[0046] Working principle description:

[0047] The motor and the annular spindle belt drive the one-piece steel collar to rotate on the frame, and rotate in the same direction as the wire ring driven by the bobbin, thereby reducing the relative linear speed between the one-piece steel collar and the wire ring, and when necessary, the relative linear speed can be set to zero.

[0048] The design of this embodiment reduces the friction of the wire ring when it rotates on the runway groove, thereby avoiding wear and high temperature caused by friction, and preventing the wire ring from flying off, burning or unstable rotation, which may lead to yarn breakage. At the same time, the technology of this embodiment can also increase the movement speed of the wire ring, thereby increasing the spindle speed and improving production efficiency.

[0050] It should be understood that the present invention is not limited to the exact construction that has been described above and shown in the drawings and that various modifications and changes may be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
