Background

The winding machine is mechanical equipment for producing inductance coils and comprises a machine frame, a feeding device, a cutter sliding seat device and a power source. The feeding device presses the wires by one or two pairs of wire feeding wheels, and the rotation of the wire feeding wheels drives the wires to advance and feed. In order to adjust the wire feeding pressure, it is conventional to set a group of wire feeding wheels to be floating, and to change the relative gap value between the wire feeding wheels by the rigid abutment of the screw rod, so as to change the magnitude of the wire feeding pressure. However, at the manufacturing stage of the wire, fluctuations inevitably occur in the diameter of the wire in the direction of its entire length. Furthermore, the angle of the wire feeding also has a deviation. Therefore, the fluctuation value of the wire feeding pressure of the silk thread is large, the wire feeding stability is influenced, and the forming size precision of the inductance coil is further influenced. Moreover, when the instantaneous pressure of the wire is too large, the wire may be broken during the actual winding process of the inductance coil, which affects the normal operation of the production line. Thus, a skilled person is urgently needed to solve the above problems.

Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings only for convenience of description of the present invention and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The following specific embodiments are combined, and the contents of the present invention are further described in detail, fig. 1 shows the structure diagram of the winding machine of the present invention, the winding machine includes a plurality of groups of cutter slides, and the winding machine surrounds the rotating core to perform circumferential uniform distribution, in the actual operation process, the feeding is continuously performed to the rotating core through the wire feeding device, and the subsequent forming of the inductance coil is performed under the combined action of the plurality of groups of cutter slides. The performance of the wire feeder is critical to the quality of the inductor coil formation. When the pressing force of the yarn feeding wheel is insufficient, the situation that the yarns cannot be fed out is easily caused. When the pressing force of the wire feeding wheel is too large, the induction coil is easy to break suddenly in the rolling process.

Fig. 2 and fig. 3 respectively show the structural schematic diagram of two views of the wire feeding device of the middle winding machine of the present invention, which is composed of a left wire feeding wheel assembly 1, a right wire feeding wheel assembly 2, a housing 3, a wire feeding guide seat assembly 5 (as shown in fig. 7), a wire feeding pressure adjusting device 6, and a driving motor 4 for providing rotary power to the left wire feeding wheel assembly 1 and the right wire feeding wheel assembly 2. Generally, the left wire feed roller assembly 1 and the right wire feed roller assembly 2 are provided in two sets and arranged to face each other. The housing 3 is arranged at the periphery of the left wire feeding wheel assembly 1 and the right wire feeding wheel assembly 2 and plays the roles of shielding and supporting. In view of the ease of adjusting the pressing force of the wire, in the wire feeding devices of the existing winding machines, the right wire feed wheel assembly 2 is designed to be floating, i.e. to be freely movable in a horizontal manner with respect to the left wire feed wheel assembly 1. In the technical solution disclosed in the present invention, the wire feeding pressure adjusting device 6 is composed of several parts, such as a mandrel 61, a fine adjustment lever 62, and an elastic member 63 (as shown in fig. 5). The abutting core shaft 61 always acts on the right wire feeding wheel assembly 2 to control the distance between the right wire feeding wheel assembly 1 and the left wire feeding wheel assembly. An external thread is arranged on the outer wall of the fine adjustment rod 62, and correspondingly, an internal thread matched with the external thread is arranged on the side wall of the housing 3, so that the fine adjustment rod 62 can be screwed in or out conveniently. The abutting core 61 is provided with a plug part, and correspondingly, a receiving cavity 621 (shown in fig. 6) matched with the plug part is formed at the corresponding end of the fine adjustment rod 62. The inserting portion and the accommodating cavity 621 are in clearance fit, and the elastic member 63 is sleeved on the abutting core shaft 61 and elastically abuts between the abutting core shaft 61 and the fine adjustment rod 62. The right wire feeding wheel assembly 2 includes a wire feeding wheel 21, a wire feeding wheel support shaft 22, and a bearing seat 23 (shown in fig. 4) fitted over the wire feeding wheel support shaft 22. The abutting core shaft 61 always abuts against the side wall of the bearing seat 23. In this way, the abutting core 61 is freely floated in the longitudinal direction of the fine adjustment lever 62 by the elastic member 63. In the winding process of the inductance coil, on one hand, the wire feeding pressure of the wire is always stabilized at a constant value, so that the forming quality of the inductance coil is ensured; on the other hand, the wire is always in an elastic stress state, and the condition of wire breakage is avoided.

It should be noted that, a wire feeding pressure adjusting device 6 is correspondingly disposed on one side of each right wire feeding wheel assembly 2, for example, in the present embodiment, the number of the right wire feeding wheel assemblies 2 is set to 2 groups, and accordingly, the wire feeding pressure adjusting devices 6 are also set to 2 groups and are disposed in parallel with each other (as shown in fig. 2).

Preferably, the elastic member 63 is a cylindrical spring or an elastic cylindrical rubber body.

As a further optimization of the wire feeding device of the winding machine, a top plate 64 is additionally provided, which is arranged on the top surface of the top mandrel 61 and/or the fine adjustment rod 62 (as shown in fig. 5 and 6). Thus, the cylindrical spring or the elastic cylindrical rubber body abuts against the abutting plate 64, and then transmits the elastic force to the abutting core 61 or the fine adjustment lever 62. When the large-diameter cylindrical spring or the elastic cylindrical rubber body needs to be replaced, only the top backup plate 64 needs to be replaced, and structural modification is not needed to be carried out on the top backup core shaft 61 or the fine adjustment rod 62, so that the application range of the rubber body is expanded.

As is known, in the long-time working process, the abutting core shaft 61 inevitably wears relative to the fine adjustment rod 62, and for this reason, a wear-resistant sleeve 65 (as shown in fig. 6) may be additionally arranged in the accommodating cavity 621 of the fine adjustment rod 62, and the abutting core shaft 61 reciprocates relative to the wear-resistant sleeve 65, so that the wear rate is greatly reduced, the later maintenance cost is reduced, the phenomenon of "inclined top" caused by an excessively large wear gap is effectively avoided, and the compression stability of the silk thread is further improved.

Finally, in order to facilitate the adjustment of the wire feeding pressure by manual operation, an adjusting hand wheel 66 may be disposed at the force-bearing end of the fine adjustment lever 62, and the adjustment may be easily performed without the assistance of a special tool.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
