Description

Technical Field

[0001] The invention relates to the technical field of spinning machines, in particular to a wire-releasing mechanism for a spinning machine and a wire-releasing method thereof. Background Art

[0002] When the spinning machine is working, the yarn needs to be released through the pay-off mechanism, and then the spinning machine takes the yarn. By setting a height adjustment structure, the tension of the yarn during delivery can be adjusted to avoid the yarn breaking and affecting the work of the spinning machine. The propulsion structure is set in the line mechanism to quickly transmit the yarn; The Chinese invention patent with the authorization announcement number CN117026439B discloses a spinning yarn discharge device for a spinning machine, which relates to the field of spinning technology. The present invention includes a bottom plate, and a support frame is fixedly connected to both sides of the top surface of the bottom plate, and the inner wall of the support frame is rotatably connected to an end column, and the inner wall of the end column is fixedly connected to a through column, and a first abutment wheel is fixedly connected to the through column, and a second abutment wheel is sleeved on the through column, and the first abutment wheel and the second abutment wheel are relatively distributed, and the inner walls of the first abutment wheel and the second abutment wheel are both provided with abutment recesses, and the inner walls of the first abutment wheel and the second abutment wheel are abutted with abutment protrusions, and the inner walls of the abutment protrusions are fixedly connected with mounting columns, and the mounting columns penetrate the first abutment wheel and the second abutment wheel, and the end of the mounting column away from the abutment protrusion is fixed to an annular sheet, and the inner edge of the annular sheet is fixedly connected to a protruding sheet. When the device is actually used, the complex twisted yarn can be quickly transmitted, which can facilitate the spinning machine to weave complex twisted yarn; However, the existing pay-off mechanism for spinning machines still has the following problems: 1. The spacing between the first abutment wheel and the second abutment wheel is adjusted by a spring, so that the device can transport the multi-twisted yarns of different thicknesses. However, the difference between the yarns of different thicknesses is small, and the elastic effect of the spring cannot slightly change the spacing between the abutment wheels, so it is not convenient to advance the yarns of different thicknesses. 2. When the spinning machine stops taking in thread, the pay-off reel will continue to rotate due to inertia and continue to pay out thread. The paid-out thread is long and it is easy to cause entanglement between the yarns. As a result, when the spinning machine stops taking in thread, the reel cannot be stopped in time and the excess thread cannot be dealt with in time. Therefore, we propose a pay-off mechanism and a pay-off method for a spinning machine to solve the above problems. Summary of the invention

[0003] The object of the present invention is to provide a pay-off mechanism for a spinning machine and a pay-off method thereof, so as to solve the problems of the existing pay-off mechanism for a spinning machine proposed in the above-mentioned background technology.

However, the difference between yarns of different thicknesses is small, and the elastic action of the spring cannot slightly change the spacing between the abutment wheels, which makes it inconvenient to advance yarns of different thicknesses. When the spinning machine stops feeding the thread, the pay-off drum will continue to rotate due to inertia and continue to pay off the thread.

Therefore, when the spinning machine stops feeding the thread, the bobbin cannot be stopped in time and the excess thread paid out cannot be processed in time.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Due to the friction force, when the second propulsion disk 33 rotates clockwise and the yarn moves right, the first propulsion disk 35 rotates counterclockwise, and the yarn is propelled by the clockwise rotation of the second propulsion disk 33 and the counterclockwise rotation of the first propulsion disk 35; Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above-mentioned embodiment 1. In the existing spinning machine pay-off mechanism, when the spinning machine stops eating the thread, the pay-off drum 26 will continue to rotate due to inertia and continue to pay off the thread.

The second motor 9 drives the reverse screw 10 to rotate clockwise, and the upper and lower two groups of clamping plates 23 threadedly connected to the reverse screw 10 move inward. The inward movement of the clamping plate 23 clamps the bottom end of the receiving rod 25. Due to the clockwise rotation of the reverse screw 10, the first bevel gear 11 fixedly connected to the reverse screw 10 rotates clockwise, so that the second bevel gear 12 and the first pulley 13 rotate counterclockwise. Due to the transmission of the transmission belt 14, the second pulley 15 rotates counterclockwise, so that the adjusting roller 16, the manual telescopic rod 20, the blocking roller 21 and the baffle plate 22 rotate counterclockwise, and the blocking roller 21 rises upward.

A method for paying off a thread of a paying-off mechanism for a spinning machine as claimed in claim 1, characterized in that: The following steps are involved: Step 1: The yarn is wound around the outer side of the pay-off drum (26), the pay-off drum (26) is snap-fitted and installed on the top end of the receiving rod (25), the yarn is pulled out, the yarn passes through the wire groove between the baffles (22) and the baffles (22) and overlaps the first yarn guide roller (27) and the second yarn guide roller (28), and then passes between the second propulsion disk (33) and the first propulsion disk (35), the end of the yarn is fixed on the spinning machine, the rotating mechanism adjusts the inclination angle of the pay-off drum (26), the electric telescopic rod (29) adjusts the height of the first yarn guide roller (27) and the second yarn guide roller (28), and adjusts the tension; Step 2: When the spinning machine is feeding the yarn, the yarn comes out from the pay-off drum (26), moves to the right between the thread groove between the baffles (22), the first yarn guide roller (27), the second yarn guide roller (28), and the second propulsion disc (33) and the first propulsion disc (35), and the propulsion structure propels the yarn to move to the right; Step 3: When the spinning machine stops feeding the yarn, the third motor (32) immediately cuts off the power supply and starts the second motor (9) inside the brake wire lifting mechanism. The second motor (9) drives the clamping plate (23) to move inward and the stop roller (21) to rotate upward through the reverse screw (10), the first bevel gear (11), the second bevel gear (12), the first pulley (13), the transmission belt (14) and the second pulley (15). The inward movement of the clamping plate (23) clamps the bottom end of the receiving rod (25), so that the receiving rod (25) and the pay-off drum (26) stop rotating, and the stop roller (21) rotates upward to lift the yarn that has escaped.
