## Abstract

A welding wire conveyor device (1) and a method for locking a pivotable roll receiver off the welding wire conveyor device (1). The device includes a drive roll receiver (11) and a pivotable pressure roll receiver (10). The pressure roll receiver (10) is coupled to a pivotable actuation mechanism (20) enabling movement to a pivoted position. The pressure roll receiver (10) may be locked in the pivoted position by a locking device (200).

## Claims

### Claim 1

A welding wire conveyor device (1) comprising:
a drive roll receiver (11);
a pressure roll receiver (10);
a pivotable actuation mechanism (20), at least one of the roll receivers supported by the pivotable actuation mechanism, the pivotable actuation mechanism (20) adapted to lock the at least one of the roll receivers in a position; and
a locking mechanism (200) including:
a locking device (23) having an outer perimeter including a recess; and
a compressible pressure mechanism (22) engageable with the outer perimeter of the locking device (23), the compressible pressure mechanism having an axis aligned with the outer periphery of the locking device, the compressible pressure mechanism having a length along the axis, the length being greater when the compressible pressure mechanism extends into the recess than when the compressible pressure mechanism is in contact with the outer perimeter of the locking device, the at least one of the roll receivers being locked in the position when the compressible pressure mechanism (22) extends into the recess of the locking device (23).

### Claim 2 (depends on 1)

The welding wire conveyor device (1) according to claim 1, wherein the pivotable actuation mechanism includes a longitudinal axis, the pivotable actuation mechanism (20) being shiftable along the longitudinal axis.

### Claim 3 (depends on 2)

The welding wire conveyor device (1) according to claim 2, further comprising a preloading mechanism (300) forcing the pressure roll receiver toward the drive roll receiver.

### Claim 4 (depends on 1)

The welding wire conveyor device (1) according to claim 1, wherein the pressure roll receiver (10) is coupled to a bushing (100) coupled to the pivotable actuation mechanism (20).

### Claim 5 (depends on 1)

The welding wire conveyor device (1) according to claim 1, wherein the pressure roll receiver (10) comprises a second drive roll receiver.
