Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 3: the embodiment discloses a rotary clamping and loosening type wire feeding device, which comprises a bottom plate 1, a wire guiding assembly and a support 7 connected to the bottom plate 1, wherein the bottom plate 1 is provided with a fixed seat 11, the fixed seat 11 is connected with a driving wire feeding wheel 8, the wire guiding assembly is hinged to the support 7 through a hinged shaft 71 and is provided with a driven wire feeding wheel 21 matched with the driving wire feeding wheel 8, the support 7 is also provided with a shifting shaft 6, two ends of the shifting shaft 6 are respectively provided with an eccentric block 61 and a shifting block 62 for driving the wire guiding assembly to rotate by taking the hinged shaft 71 as an axis, and the eccentric block 61 is connected with a driving device for driving the shifting shaft 6 to;

in the working process, the driven wire feeding wheel 21 and the driving wire feeding wheel 8 need to rotate synchronously, so the driven wire feeding wheel 21 and the driving wire feeding wheel 8 are provided with meshed gears. The passive wire feeding wheel 21 and the active wire feeding wheel 8 are both provided with ring grooves matched with the cross section of the wire, and the ring grooves of the two wire wheels are arranged oppositely. The driving wire feeding wheel 8 is connected with a rotating power device for feeding wires.

The driving device of the embodiment is an air cylinder 5, the air cylinder 5 is connected to the guide wire assembly through an air cylinder bracket 51, and the power output end of the air cylinder 5 is connected to the eccentric block 61.

The specific structure that the shifting block 62 drives the guide wire assembly to rotate by taking the hinge shaft 71 as the axis is as follows: the upper end of the support 7 is provided with an upper extension section 72, and when the shifting shaft 6 rotates, the shifting block 62 is extruded on the upper extension section 72, so that the guide wire assembly can be driven to swing by a certain angle. In order to limit the swing angle of the wire pressing bracket 2 and prevent the distance between the passive wire feeding wheel 21 and the active wire feeding wheel 8 from being too large, a wire feeding swing shaft 22 is further disposed between the wire guiding assembly and the fixing base 11 in this embodiment, and the wire feeding swing shaft 22 and the wire pressing bracket 2 are in clearance fit. The size of the gap between the two determines the swing angle of the wire feeding assembly.

Preferably, the thread guiding assembly of the present embodiment comprises a thread pressing bracket 2 and a thread guiding plate 3 connected to the thread pressing bracket 2, wherein a thread guiding groove 31 is formed on a connection surface of the thread pressing bracket 2 of the thread guiding plate 3, and the driven thread feeding wheel 21 is connected to the thread pressing bracket 2.

In order to further improve the yarn guiding effect, the yarn guiding assembly of this embodiment further includes a yarn feeding and guiding seat 32 and a yarn discharging and guiding seat 33 disposed at the yarn feeding end of the yarn guiding plate 3.

Since the nailing section is usually two nails simultaneously nailed to the product, the wire guide assemblies of this embodiment are preferably two, with the two wire guide assemblies being juxtaposed.

When wire threading is needed, the air cylinder 5 contracts, the shifting block 62 extrudes the upper extension section 71, so that a rotating torque is generated between the wire guiding component and the support 7, and the wire guiding component can swing upwards at a small angle within the range of the gap between the wire pressing bracket 2 and the wire feeding swing shaft 22, so that the gap between the driven wire feeding wheel 21 and the driving wire feeding wheel 8 is expanded. The wire can enter between the passive wire feeding wheel 21 and the active wire feeding wheel 8 from the wire feeding wire guiding seat 32 and the wire guiding groove 31 in sequence, and then enters the bending and nailing part of the nail head through the wire discharging wire guiding seat 33. After the wire threading is finished, the air cylinder 5 pushes forwards, and because the distance between the hinged point of the air cylinder 5 and the eccentric block 61 and the axle center of the shifting shaft 6 is greater than the width of the shifting block 62, when the air cylinder 5 pushes forwards, although the shifting block 62 also acts on the upper extension section 72, the passive wire feeding wheel 21 still has the pressure attached to the active wire feeding wheel 8, and the pressure can extrude the internal wire to realize the wire feeding through friction.

Compared with the prior art, the gap between the passive wire feeding wheel 21 and the active wire feeding wheel 8 can be slightly enlarged in the wire feeding process, so that the wire can enter the inside of the wire guide wheel quickly, accurately and efficiently, and after the wire feeding is finished, the two wire feeding wheels can be elastically extruded under the action of the air cylinder 5 to drive the wire to move forwards through friction force. The wire feeding and guiding seat 32 and the wire discharging and guiding seat 33 further improve the wire guiding effect and relieve the friction between the wires and the wire guiding plate 3 and the wire pressing bracket 2.

The embodiment also discloses a nail head, which comprises the rotary clamping and loosening type wire feeding device.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
