Description

TECHNICAL FIELD

[0001] The utility model relates to the improvement of laser machine, especially to the improvement of cloth conveying and unfolding mechanism of laser machine. BACKGROUND

[0002] Laser machine is the general term of laser engraving machine, laser cutting machine and laser marking machine. When cloth is engraved, cut or marked by laser machine, the cloth needs to be completely unfolded. However, when the cloth is unwound and conveyed to the working platform of laser machine, due to the softness of the material, the cloth can be kept unfolded in the conveying direction under the action of traction force, but it is easy to be folded in the vertical conveying direction, resulting in wrinkles in the middle. In order to overcome this problem, the existing technology generally uses up-and-down cooperating thread rollers for conveying, and is equipped with a thread roller rotating power source. However, the setting of thread rollers and power source leads to complex structure and increased cost. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above technical problem, the utility model is implemented by adopting the following technical scheme: the cloth conveying and unfolding mechanism of the laser machine comprises a cloth unwinding roller group, characterized in that: the cloth unwinding roller group is arranged on the inlet side of the laser machine, a cloth unfolding assembly is arranged on the cloth unwinding path of the cloth unwinding roller group, the cloth unfolding assembly comprises a rocker arm and an arc-shaped rod, the rocker arm is arranged in two left-right symmetrical parts, the inlet end of the laser machine is provided with a rocker arm mounting seat, the inner end of the rocker arm is arranged on the rocker arm mounting seat in a swing-adjustable manner, a position adjusting part is arranged between the corresponding rocker arm and the rocker arm mounting seat, the arc-shaped rod is connected between the outer ends of the two rocker arms to support and unfold the unwound cloth.

[0005] The position adjusting part is an arc-shaped groove arranged on the rocker arm mounting seat and a fastener arranged on the rocker arm, and the fastener is locked and matched with the arc-shaped groove.

[0006] The bending direction of the arc-shaped rod is consistent with the length direction of the rocker arm.

[0007] The working platform of the laser machine is provided with a suction conveying mechanism.

[0008] The height of the arc surface of the arc-shaped rod is 40-70mm.

[0009] The improved cloth conveying and unfolding mechanism of the laser machine is composed of a rocker arm capable of changing the supporting angle and an arc-shaped rod, mainly used for conveying flexible cloth, and can automatically unfold the two sides of the unwound cloth without wrinkles in the middle.
