Description

Technical Field

[0001] This utility model relates to the field of wire binding machine technology, and in particular to a pressure-adjustable wire feeding structure for a wire binding machine. Background Technology

[0002] In existing technologies, manufacturers of aluminum mold pull tabs still need to manually bundle them for transportation after production, which is time-consuming, labor-intensive, and requires a large amount of manpower. This increases labor costs for manufacturers, wastes resources, and results in low work efficiency and high labor intensity. Furthermore, due to the sharp shape of the aluminum mold pull tabs themselves, manual bundling is difficult and may cause scratches and cuts. Bundling machines, also known as strapping machines or packing machines, are used to reinforce packaged goods, preventing them from scattering during handling and storage due to loose bundling. They should also be neat and aesthetically pleasing. Existing bundling machines on the market include automatic tape bundling machines, automatic packing strap bundling machines, and automatic steel strap bundling machines. However, regardless of the type of bundling machine, the pressure on the wire during the wire straightening process cannot be adjusted, resulting in poor flexibility of use. The quality of wire pressing is uncontrollable, which can easily lead to loose or failed bundling, reducing the reliability of bundling.

[0003] Chinese utility model patent application number 202221498287.1 discloses an aluminum mold pull-tab binding machine, including a frame. Along the workpiece transport direction, a feeding mechanism, a pressing transition mechanism, and a wire feeding and straightening mechanism are sequentially arranged on the frame, all aligned in a straight line. The pressing transition mechanism is located between the feeding mechanism and the wire feeding and straightening mechanism, and wire-holding mechanisms are arranged on both sides of the pressing transition mechanism. Perpendicular to the workpiece transport direction, a discharging mechanism and a wire twisting mechanism are arranged. The wire twisting mechanism is located directly above the wire-holding mechanism, and a wire-cutting mechanism is located between the wire twisting mechanism and the wire feeding and straightening mechanism. The wire feeding and straightening mechanism includes two parallel wire feeding and straightening units, with a wire-cutting mechanism at the wire outlet end of each unit. Each wire-cutting mechanism corresponds to a wire twisting mechanism. However, this aluminum mold pull-tab binding machine cannot adjust the pressure of the wire, resulting in poor flexibility, uncontrollable wire pressing quality, and a tendency for loose or failed binding, thus reducing binding reliability.

The plurality of mounting bolts 13 are arranged side by side at intervals on one side of the mounting base plate 1 and are threaded through the mounting base plate 1 and connected to the mounting base plate 1. One end of the mounting bolts 13 abuts against the mounting plate 12. The mounting assembly, through the cooperation of the mounting plate 12 and the mounting bolts 13, provides adjustable space for the driven thread pressing wheels 11. The support includes a mounting plate 12, which serves as a sliding mounting structure in the mounting groove, providing mounting support for the driven wire pressing wheel 11. The position of the driven wire pressing wheel 11 can be adjusted by adjusting the position of the mounting plate 12 in the mounting groove, thereby adjusting the distance between the driven wire pressing wheel 11 and the driven wire feeding wheel 10. The mounting bolt 13 serves as an adjustment support structure on the side of the mounting base plate 1. The mounting bolt 13 can be rotated to extend or retract relative to the slider pressure plate 8, thereby adjusting the abutment position between the mounting bolt 13 and the mounting plate 12, thereby adjusting the position of the mounting plate 12 to adjust the position of the driven wire pressing wheel 11.

[0026] Return springs are provided between the side of the mounting pressure plate 12 and the mounting base plate 1, and between the side of the pressure slider 6 and the mounting base plate 1. The return springs are located on the side of the mounting pressure plate 12 and the pressure slider 6 away from the bolt, and their two ends abut against the mounting base plate 1 and the mounting pressure plate 12 or the pressure slider 6, respectively. The return springs are used to provide elastic return support for the mounting pressure plate 12 and the pressure slider 6, so that when the pressure bolt 9 and the pressure slider 6 are disengaged or the mounting bolt 13 and the mounting pressure plate 12 are disengaged, the corresponding pressure slider 6 or the mounting pressure plate 12 is reset.

[0027] The active wire feeding wheel 2, the driven wire feeding wheel 10, and the driven wire pressing wheel 11 are provided with limiting grooves on their sides corresponding to the iron wire. The limiting grooves are set as annular groove structures, and the limiting grooves are used to limit the iron wire.

[0028] The number and position of each component in this technical solution can be adjusted according to actual usage requirements.

[0029] Working principle: When straightening the wire is required, the wire is passed through the limiting groove between the wire feeding wheel and the wire pressing wheel and out through the guide rod 5. The servo motor is started, and the servo motor drives the active wire feeding wheel 2 and the active wire pressing wheel 7 to rotate through the transmission gear 3. The wire is pressed by the active wire feeding wheel 2 and the active wire pressing wheel 7 and moves with the rotation of the active wire feeding wheel 2, thereby achieving straightening and wire feeding. The wire pressing bolt 9 can be rotated to drive the wire pressing slider 6 to slide along the adjustment groove, thereby adjusting the distance between the active wire pressing wheel 7 and the active wire feeding wheel 2 to adjust the clamping force on the wire. When the wire pressing bolt 9 disengages from the wire pressing slider 6, that is, when the two are not in contact, the wire pressing slider 6 is reset under the action of the return spring. The adjustment principle of the mounting component is the same as the adjustment principle of the wire pressing bolt 9, so it will not be described again here. The clamping force on the wire can be adjusted by rotating the mounting bolt 13 to adjust the distance between the driven wire pressing wheel 11 and the driven wire feeding wheel 10.

[0030] The advantages of this utility model are its simple structure, the wire feeding mechanism which can guide the wire feeding and ensure the straightening effect of the wire, the wire pressing mechanism which can flexibly adjust the pressing force on the wire, making it highly flexible in use, and the driven mechanism which works in conjunction with the wire loosening mechanism to ensure that the pressing quality is controllable, avoid the phenomenon of loose or failed binding of the wire, and improve the binding reliability.

[0031] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
