Description

Technical Field

[0001] The invention relates to the technical field of yarn binding machines, in particular to a novel pot-type yarn binding machine wiring structure. Background Art

[0002] Yarn binding machines are functional equipment in the cable industry. Depending on the position of the yarn balls relative to the cable center, they are categorized as eccentric (the yarn ball centerline is outside the cable center) or concentric (the yarn ball centerline is aligned with the cable center). Eccentric binding machines have lower speeds due to the eccentricity, but they facilitate yarn changes and splicing, and production is not limited by yarn length. Concentric binding machines can use long yarn balls, requiring a reserve yarn storage system.

[0003] There are active and passive payoffs for controlling the tension of the yarn balls; and there are variable and constant tension methods. For constant tension control at low levels, active payoff with constant tension torque control is generally adopted. Based on the number of yarn balls, there are single-end and double-end binders. Single-end binders have a fixed winding direction for the yarn. Double-end binders have two balls of yarn wound in both directions, both left and right. For SZ periodic reversing twisting, a double-end fixed twisting structure is used for cable formation.

[0004] For double-end binding machines, the binding point is divided into two types based on the position of the yarn balls and the binding point. The binding point is located in the middle of the two yarn balls (winders are arranged face to face) or on one side (winders are arranged back to back), commonly known as "face to face" and "back to back". For the back to back arrangement, the far end of the yarn must be guided to the binding point through the center hole to achieve cross binding at the same point (near the same point).

[0005] The bobbin winders are classified into plate type, rod type, and pot type (the yarn balls are placed in the pot). Plates and rods are installed near the yarn outlet, and the plates and rods must be removed to remove the yarn balls. Pots are installed far from the yarn outlet, making it easy to remove and install the yarn balls, with good concentricity. High-speed rotation can reduce the effects of air flow on tension.

[0006] Existing yarn-binding machines use a two-point shuttle feed system: one for inlet and one for outlet. A pot-type system is commonly used, with a ceramic eyelet positioned for yarn entry and a ceramic eyelet or guide wheel for yarn exit. Chinese patent ZL201721375278.2 discloses a cable-binding machine routing structure that achieves long-distance spiral yarn delivery by adding intermediate guide rods. However, the use of guide rods or ceramic eyelets primarily relies on static friction, resulting in significant fluctuations in yarn tension. Summary of the Invention

[0007] The purpose of the present invention is to solve the shortcomings of the existing technology and provide a yarn-binding machine yarn-feeding method that slows down the fluctuation of the yarn tension when the yarn itself is reciprocatingly paid out left and right, thereby reducing the peak value of the yarn tension, reducing the uniformity of the tension of the bundle of the yarn to the SZ twisted sleeve and reducing the risk of strangulation of the sleeve.

[0008] In order to achieve the above-mentioned purpose, a new type of pot-type yarn binding machine yarn feeding structure is designed, the yarn binding machine includes a yarn binding ball and a yarn binding pot, and a yarn feeding path for guiding the yarn to enter is arranged along the edge of the yarn binding pot, and the yarn feeding path includes at least one automatic deflection guide wheel group, and the yarn outlet of the yarn binding ball is connected to the automatic deflection guide wheel group, and the automatic deflection guide wheel group can realize left and right adaptive deflection in the axial direction; at least one first directional guide wheel group and at least one second directional guide wheel group, the first directional guide wheel group and the second directional guide wheel group are fixed at equal angles on the circumference of the yarn binding pot; the yarn of the yarn binding ball passes through the automatic deflection guide wheel group, the first directional guide wheel group and the second directional guide wheel group in turn.

[0009] Preferably, a yarn binding pot outlet guide wheel group is provided at the yarn binding pot outlet position, and the yarn binding pot outlet guide wheel group is connected to the yarn binding mold or the yarn guide wheel.

[0010] Preferably: the first directional guide wheel group and the second directional guide wheel group include a fixed plate and a guide wheel, the fixed plate is provided with an angle tightening pin, the guide wheel is fixed to the fixed plate through a guide wheel bracket, the guide wheel includes a guide wheel shaft and a guide wheel bearing, the guide wheel bearing is arranged in the guide wheel shaft, a spacer is provided on the outside of the guide wheel shaft, and the guide wheel shaft is fixed to the guide wheel through a locking nut.

[0011] Preferably: the automatic deflection guide wheel includes a fixed plate and a guide wheel, a steering bearing and a spring are provided in the middle of the fixed plate, the spring is connected to an axle retaining spring, a marble is provided on the axle retaining spring, and a limit pin is also provided on the right side of the fixed plate.

[0012] Preferably: the guide wheel also includes a guide wheel shaft and a guide wheel bearing, the guide wheel bearing is arranged in the guide wheel shaft, a spacer is provided on the outside of the guide wheel shaft, and the guide wheel shaft is fixed to the guide wheel by a locking nut.

[0013] Preferred: The routing method is as follows: the yarn ball is fixed on the expansion sleeve of the yarn binding machine, and the yarn is passed through the automatic deflection guide wheel group, the first directional guide wheel group, the second directional guide wheel group and the yarn binding pot outlet guide wheel group in sequence along the yarn routing route. The yarn is guided to the yarn binding mold or the yarn guide wheel through the yarn binding pot outlet guide wheel group, and finally wound around the cable core. The yarn binding pot rotates at high speed in a certain direction, pulling and driving the cable core forward, and spirally winding the yarn around the cable core.

[0014] Compared with the existing technology, the advantages of the present invention are: slowing down the fluctuation of the yarn binding tension when the yarn itself is reciprocating left and right, thereby reducing the peak value of the yarn binding tension, reducing the uniformity of the tension of the binding yarn on the SZ twisted sleeve and reducing the risk of strangulation of the sleeve, and using guide wheel rolling instead of direct friction to minimize the yarn binding tension of the output yarn.
