2. Since a plurality of yarns separated independently from each other are drawn out after being combined into one ribbon from one winding head, the lengths of the yarns on the left and right sides are inevitably inconsistent due to the bending radius when the winding direction is changed, so that friction is generated between the yarns to cause fuzzing of the yarns, the tensions are also different, and the performances of the raw materials cannot be fully exerted.

The utility model discloses a theory of operation:

when the numerical control device works, the servo motor receives an instruction of a numerical control system, the speed reducer drives the main driving chain wheel to rotate, the main driving chain wheel drives the precise roller chain to make the precise roller chain do circular rolling motion along the guide supporting wheel, meanwhile, the precise roller chain drives the feed driving chain wheel meshed with the precise roller chain to do rotary motion, the feed driving chain wheel drives the feed gear coaxially arranged with the feed driving chain wheel to do synchronous rotary motion, and the feed gear drives the feed rack to drive the wire winding head arranged on the feed rack to do radial linear reciprocating feed motion. The multi-winding head synchronous feeding mechanism has the following characteristics:

1: low manufacturing cost, convenient maintenance, strong anti-pollution capability and low required driving power.

The main drive adopts a precision roller chain drive form, the structure of the form is simplest and most compact, the required driving force is minimum, the cost is minimum, and a gear drive form and a synchronous belt drive form which are more complex in structure are avoided. The latter two forms, with the increase in the number of the forming heads and the increase in the feed stroke, are not only more costly than the transmission forms used herein, but also require more drive power. The large central disc of the former: the guide supporting wheel is fixed without using a bearing for supporting, and the large and medium discs in the last two forms: the large gear disc or the large synchronous belt wheel disc needs to do circular motion, so a reliable radial support and axial support structure needs to be additionally arranged, and the structure is more complicated than that of the former. The power required to rotate it is certainly much greater than that required to drive the precise roller chain to move.

2: the combination form of the number of the wire winding heads is diversified, the accumulation and the overhead of the end sockets are slowed down, and the winding efficiency is improved.

In the actual winding process, different process layers often adopt different tangent points, and the mechanism can provide the number of the wire winding heads of which the tangent points are integral multiples. The winding heads and the feeding mechanism are uniformly distributed along the circumference, the inclusion of the outer diameter of the guide supporting wheel to the number of the winding head combinations is fully considered, the number of the winding heads used in practice can be conveniently adjusted through the auxiliary positioning dividing disc, and the winding heads after adjustment are uniformly distributed along the circumference and the radial direction, so that the accumulation and the overhead phenomenon near the end heads are greatly relieved in the practical winding process, and the winding efficiency is improved in a multiplied manner.

3: has stable yarn tension and can realize small yarn tension.

The yarn path is short and simple, except the winding head, other parts contacting with the yarn are rotating parts, the friction resistance is extremely small, and the yarn ball is arranged on a tensioner capable of controlling the tension in a follow-up manner, so that the structure is guaranteed for providing small yarn tension, and the characteristic is particularly important for winding the rubber airbag with high winding tension value and low tension. Since the paths of the individual winding heads are identical in structure, their tensions are essentially identical in synchronization.

4: the quick response of the movement is good, and the operation is stable.

Because the single linear guide rail pair is adopted for positioning and guiding, external loads are all born by the rack, the structure is optimized and designed to ensure that the feeding mechanism is light, the guide rail pair adopts a micro-clearance fit mode, the running resistance is small, and therefore, the inertia of the moving body is small, and the feeding mechanism has excellent quick response and motion stability.

5: the required feed force is small.

The system adopts a structural form that the feeding mechanism is uniformly and radially distributed along the circumference in the vertical plane, so that the required feeding force caused by the weight of the moving piece in the feeding mechanism is almost counteracted, and only the running resistance and the tension of the moving piece and the dynamic load caused by the speed change of the moving piece are required to be overcome. Generally, the feeding force caused by the weight of the moving part of each feeding mechanism is larger than the sum of the last three parts, so that the feeding force required by the layout form is very small.
