[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] like Figures 1 to 3 As shown, a twisting machine high-twist yarn unwinding device comprises a frame 1, on which a plurality of unwinding rollers for positioning unwinding fringe are arranged, and on the frame 1, a broken end clamping assembly, a rear tensioning roller 2, and a rear tension adjusting assembly are arranged in sequence along the direction of releasing the yarn from the unwinding fringe;
[0027] The broken end clamping assembly includes a front tensioning roller 4, a fixed clamping plate 5, a movable clamping plate 6, a front tension adjusting assembly 7 and a rocker arm 8. The front tensioning roller 4 and the movable clamping plate 6 are connected by a pair of rocker arms 8 respectively arranged on both sides. The rocker arm 8 is rotatably arranged on the frame 1 through a rotating shaft 3, and the rotating shaft 3 is located between the front tensioning roller 4 and the movable clamping plate 6.
[0028] The fixed clamping plate 5 is arranged on the frame 1 and is arranged opposite to the movable clamping plate 6;
[0029] The front tension adjusting assembly 7 is arranged on the frame 1 and connected to the rocker arm 8. The front tensioning roller 4 overcomes the resistance of the front tension adjusting assembly 7 under the action of the yarn tension, so that the movable clamping plate 6 is away from the fixed clamping plate 5, so that the yarn passes between the movable clamping plate 6 and the fixed clamping plate 5;
[0030] Among them, both ends of the rear tensioning roller 2 are slidably arranged on the frame 1 through a slider 9, and the rear tension adjusting component is connected to the slider 9, and the rear tension adjusting component is used to adjust the tension of the rear tensioning roller 2 on the yarn.
[0031] The yarn released by the unwinding fringe passes through the bottom of the front tension roller 4, between the movable clamping plate 6 and the fixed clamping plate 5, the bottom of the rear tension roller 2, and several guide rollers, and is wound on the rotating winding fringe. During the process, the yarn is tensioned under the pressure of the front tension roller 4 and the rear tension roller 2, and the front tension roller 4 is lifted under the action of the yarn tension, and the movable clamping plate 6 is moved away from the fixed clamping plate 5 by means of the rocker arm 8. When the yarn on the unwinding fringe is released, or the yarn between the front tension roller 4 and the unwinding fringe is disconnected, the front tension roller 4 rotates downward under the action of the front tension adjustment component 7, and at the same time, the movable clamping plate 6 approaches the fixed clamping plate 5 to clamp the yarn. Since the yarn is still wrapped around the winding fringe before the winding fringe stops suddenly, the tension of the yarn increases and the yarn overcomes the resistance of the rear tension adjusting component, driving the rear tensioning roller 2 to rise, so as to shorten the length of the yarn bending under the pressure of the rear tensioning roller 2, that is, to supplement the winding length before the winding fringe stops suddenly, and avoid the secondary disconnection of the yarn between the rear tensioning roller 2 and the winding fringe.
[0032] The utility model adjusts the tension of the yarn through the rear tension roller 2 and the rear tension adjustment component, and assists in tension adjustment through the broken end clamping component composed of the front tension roller 4, the fixed clamping plate 5, the movable clamping plate 6, the front tension adjustment component 7 and the rocker arm 8. In addition, when the yarn on the unwinding wire fringe is broken, the front tension roller 4 loses the support of the yarn tension, so that the movable clamping plate 6 can be driven by the front tension adjustment component 7 and cooperate with the fixed clamping plate 5 to clamp the broken end of the yarn, thereby facilitating subsequent wiring.
[0033] Among them, the rocker arm 8 includes a front force arm 801 located between the front tensioning roller 4 and the rotating shaft 3, and a rear force arm 802 located between the rotating shaft 3 and the movable clamp 6. The length of the front force arm 801 is greater than the length of the rear force arm 802. The front tension adjustment component 7 is connected to the rear force arm 802 to facilitate reducing the stroke of the movable clamp 6 when clamping the yarn, so that when the yarn breaks near one end of the unwinding wire fringe, the movable clamp 6 can respond quickly.
[0034] The front tension adjustment assembly 7 includes a tension spring 701, a sleeve 702 and a screw 703. The movable splint 6 is located below the fixed splint 5. The two ends of the tension spring 701 are movably connected to the screw 703 and the rear force arm 802 respectively. The sleeve 702 is arranged on the frame 1, and the sleeve 702 is threadedly connected to the screw 703 through the internal thread of the inner wall, that is, the pressure of the front tension roller 4 on the yarn and the clamping force of the movable splint 6 on the yarn are adjusted through the screw 703. The function of the tension spring 701 is that when the yarn is disconnected near one end of the unwinding wire fringe, the accumulated elastic potential energy is released to drive the rocker arm 8 to rotate, so that the movable splint 6 cooperates with the fixed splint 5 to clamp the yarn.
[0035] The rear tension adjustment assembly includes a plurality of counterweights 10, and a slide groove 11 for sliding the slider 9 and the counterweights 10 is provided on the frame 1, and the plurality of counterweights 10 are supported on the slider 9. The yarn passes under the rear tension roller 2, and the tension applied by the rear tension roller 2 to the yarn is adjusted by increasing or decreasing the counterweights 10 or replacing the counterweights 10 with different weights, so as to adjust the yarn tension.
[0036] Furthermore, the use of a spring to provide pulling force for the tensioning roller is avoided. However, when the yarn is broken and clamped, the tension on the yarn increases instantly during the process of being wound around the thread tassel. Due to the presence of the spring, even if the tensioning roller overcomes the resistance of the spring and rises under the action of the yarn tension, the tension of the yarn cannot be released, thereby causing the problem of secondary yarn breakage.
[0037] What is further optimized in the above embodiment is that a plurality of engaging teeth 12 are provided on the mutually adjacent sides of the fixed splint 5 and the movable splint 6, and the fixed splint 5 and the movable splint 6 clamp the broken end of the yarn by the mutual engagement of the plurality of engaging teeth 12, so as to enhance the clamping effect of the yarn.
[0038] Further optimized in the above embodiment is that both the fixed clamping plate 5 and the movable clamping plate 6 include a tooth plate 13 with engaging teeth 12, and a base 14 connected to the tooth plate 13, so as to facilitate the replacement of the worn tooth plate 13 and ensure the clamping effect of the yarn. Among them, the base 14 of the movable clamping plate 6 is connected to the rocker arm 8, and the base 14 of the fixed clamping plate 5 is connected to the frame 1.
[0039] Preferably, the tooth plate 13 is made of elastic rubber material to facilitate clamping of the yarn.
[0040] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
