The driving gear connecting assembly is provided with a driving gear, and the driving gear is provided with a driving mechanism to drive the driving gear to rotate. The driven gear connecting assembly is provided with a driven gear, and the driven gear connecting assembly is provided with a clamping assembly to press the driven gear towards the driving gear. Both the driven gear and the driving gear are provided with a groove, and the groove at the point where the driven gear and the driving gear are pressed together forms a channel to accommodate the baling wire.

[0007] Furthermore, the groove is a V-shaped groove, suitable for bundling wires of different diameters.

[0008] Furthermore, the driven gear connecting assembly includes a connecting seat connected to a fixed plate, the connecting seat is provided with a slide bar, the slide bar is provided with a slider that slides on the slide bar, the driven gear is connected to one end of the slider, and the clamping assembly is located between the connecting seat and the slider.

[0009] Furthermore, the clamping assembly includes a movable rod connected to the connecting seat. The slider is provided with a slider bracket, and the slider bracket has a through hole for the movable rod to pass through. After the movable rod passes through the through hole, it is screwed to the end of the movable rod by a nut to restrict the movable rod from sliding out. A spring is sleeved on the movable rod to push the slider out. The clamping force between the driven gear and the driving gear is automatically adjusted by the clamping assembly.

[0010] Furthermore, the connecting seat is equipped with a cylinder for pushing the moving rod. The clamping force between the driven gear and the driving gear can also be adjusted by the cylinder.

[0011] Furthermore, an encoder is connected to the drive gear to control the feed length of the bundling line.

[0012] The beneficial effects of this utility model are:

[0013] 1. The wire feeder in this utility model has a compact and simple structure, and the gear transmission in this patent can ensure a constant instantaneous transmission ratio, high stability, and accurate transmission of actions. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0018] Example 1: A wire feeding wheel structure for a small baler includes a fixed plate 1, a drive gear connecting assembly 2 and a driven gear connecting assembly 3 on the fixed plate 1, a drive gear 4 on the drive gear connecting assembly 2, and an encoder 11 connected to the drive gear 4.

[0019] The drive gear 4 is provided with a drive mechanism 5 that drives the drive gear 4 to rotate. The driven gear connecting assembly 3 is provided with a driven gear 6. The driven gear connecting assembly 3 is provided with a clamping assembly 7 that presses the driven gear 6 against the drive gear 4. Both the driven gear 6 and the drive gear 4 are provided with a groove 8. The groove 8 is a groove with a V-shaped cross section. The groove 8 at the point where the driven gear 6 and the drive gear 4 are pressed together forms a channel 9 for the packing line to pass through.

[0020] The driving gear connecting assembly 2 includes a connecting seat 2.1 connected to the fixed plate 1, a slide bar 2.2 provided on the connecting seat 2.1, a slider 10 that slides on the slide bar 2.2, a driven gear 6 connected to one end of the slider 10, and a clamping assembly 7 located between the connecting seat 2.1 and the slider 10.

[0021] The clamping assembly 7 includes a movable rod 7.1 connected to the connecting seat 2.1. The connecting seat 2.1 is provided with a cylinder 2.3 for pushing the movable rod 7.1. The slider 10 is provided with a slider bracket 10.1. The slider bracket 10.1 is provided with a through hole 10.2 for the movable rod 7.1 to pass through. After the movable rod 7.1 passes through the through hole 10.2, it is screwed to the end of the movable rod 7.1 by a nut 10.3 to restrict the movable rod 7.1 from sliding out. A spring 7.2 is sleeved on the movable rod 7.1 to push the slider 10 out.

[0022] During operation, a driving force from other components and drive mechanism 5 (i.e., the bevel gear in the figure) can drive the drive gear 4 to rotate. The drive gear 4 drives the driven gear to rotate. The moving rod 7.1 pushes the slider 10 out under the action of the spring 7.2. Since the driven gear 6 is fixed on the slider 10, the driven gear 6 and the drive gear 4 are close together. The packing line passes through the channel 9 formed by the grooves of the driven gear 4 and the drive gear 6. When the drive gear 4 and the driven gear 6 rotate, they drive the packing line to be fed and wound. The length of the packing line is precisely controlled by the encoder 11 on the drive gear 4.

[0023] The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
