Description

Technical Field

[0001] The utility model relates to the technical field of elastic weft yarn production, in particular to a thread-running prevention mechanism for elastic weft yarn production. Background Art

[0002] Elastic weft yarn is a weft yarn with white or solid color, including ring-spun PA66 / cotton core-spun yarn. It is a weft material for weaving radial tire cord fabric. The inner core is made of PA66UDY, which has the characteristics of high elongation and no shrinkage after stretching.

[0003] After the production of elastic weft yarn is completed, it needs to be wound on the bobbin. During the winding process, an anti-runaway structure is required. However, the existing anti-runaway structure still has some shortcomings in actual use:

[0004] 1. After the elastic weft yarn is transported through the wire wheel, it needs to be wound up. In order to make the elastic weft yarn evenly wound on the winding drum, the elastic weft yarn needs to be evenly wound on the winding drum. In order to ensure even winding, the winding drum is moved at the same time. However, the winding drum is large in size, which consumes more kinetic energy than moving the outlet end of the elastic weft yarn.

[0005] 2. During the weft yarn transportation process, it passes through the wire wheel. However, when the machine is powered off, the taut wire sand on the wire wheel will rebound. The existing wire wheel cannot be adjusted according to the tightness of the wire sand, which affects the normal use of the device when the machine is started again. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings in the prior art that the winding drum is large in size, consumes more kinetic energy than driving the outlet end of the elastic weft yarn to move, the wire wheel cannot be adjusted according to the tightness of the wire sand, and the normal use of the device is affected when the machine is started again. A wire-running prevention mechanism for the production of elastic weft yarn is proposed to solve the shortcomings in the prior art that the winding drum is large in size, consumes more kinetic energy than driving the outlet end of the elastic weft yarn to move, the wire wheel cannot be adjusted according to the tightness of the wire sand, and the normal use of the device is affected when the machine is started again.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A wire-running prevention mechanism for elastic weft yarn production comprises a base, a threading ring is arranged above the base, a nut is slidably connected inside the base, a connecting sleeve is fixedly connected to the top of the nut, a screw rod is passed through the connecting sleeve, and the top of the screw rod is fixedly connected to the bottom of the threading ring, and a moving component for driving the threading ring to move is arranged inside the base;

[0009] Two clamping plates are fixedly connected to the top of the base, two guide rollers are arranged between the two clamping plates, connecting columns are fixedly connected to the sides of the two clamping plates away from each other, and pulling components for pulling the corresponding guide rollers are arranged on the sides of the two connecting columns away from each other.

[0010] In a possible design, the moving assembly includes a driving motor fixedly connected to a base, a reciprocating screw is rotatably connected to the base, and a nut is threadedly sleeved on an outer wall of the reciprocating screw.

[0011] In a possible design, the pulling assembly includes sliding sleeves fixedly connected to both sides of the connecting column, sliding rods are slidably connected in the two sliding sleeves, the ends of the two sliding rods away from each other are fixedly connected to connecting shafts, and one end of the guide roller is fixedly connected to one end of the connecting shaft, a spring is fixedly connected between the connecting shaft and the sliding sleeve, and the spring sleeve is arranged on the outer wall of the sliding rod.

[0012] In a possible design, the top of the connecting sleeve is rotatably connected to the nut, and the nut threaded sleeve is arranged on the outer wall of the screw rod, a sliding groove is arranged in the connecting sleeve, and the bottom of the screw rod is fixedly connected with a guide plate, and the guide plate is slidably connected in the sliding groove.

[0013] In a possible design, the clamping plate is provided with two through slots, and the connecting shaft slides through the through slots.

[0014] In a possible design, two limit plates are fixedly connected to the outer wall of the connecting shaft, and the sides of the two limit plates close to each other respectively touch the two sides of the clamping plate.

[0015] In the present application, the elastic weft yarn passes between two guide rollers. In order to ensure the tightness of the elastic weft yarn, it needs to pass from under the right guide roller, pass from over the left guide roller, and be output from the threading ring to the outside. The elastic weft yarn passes through the threading ring and rotates the nut. The nut rotates on the outer wall of the screw to adjust the height of the screw. At the same time, the guide plate at the bottom of the screw slides in the connecting sleeve. At the same time, the drive motor is started. The output shaft of the drive motor drives the reciprocating screw to rotate, so that the nut moves back and forth on the reciprocating screw, thereby achieving a uniform winding effect. When the equipment stops, the elastic weft yarn contracts, and the spring is pulled between the connecting shaft and the sliding sleeve to drive the sliding rod to slide in the sliding sleeve, and the connecting shaft slides in the through groove, so that the two guide rollers are close to each other at the same time to form a clamping effect on the elastic weft yarn.

[0016] In the utility model, the anti-thread-running mechanism for elastic weft yarn production can reciprocate the nut on the reciprocating screw rod by pulling the assembly, and the screw rod can be raised and lowered on the connecting sleeve to adjust the height of the elastic weft yarn outlet end by binding the threading ring, thereby achieving the effect of adjusting the tightness of the elastic weft yarn;

[0017] In the utility model, the anti-thread-running mechanism for elastic weft yarn production can drive the sliding rod to pull the connecting shaft through the contraction of the spring through the anti-thread-running component, so that the two guide rollers are synchronously close to each other to clamp the elastic weft yarn;

[0018] In the utility model, not only the elastic weft yarn is clamped by the mutual approach of the two guide rollers, but also the threading ring is height-adjusted to adjust the tension of the elastic weft yarn, and the reciprocating movement of the nut can make the elastic weft yarn evenly wound on the winding drum.
