Description

[0029] The present invention provides a profile transfer mechanism and a loading and unloading device. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments.

At this time, under the action of the linear drive 23, the longitudinal feeding frame 22 is lifted up to the set height as a whole, and the profile to be cut is loaded onto the loading side of the longitudinal feeding frame 22. The longitudinal feeding frame 22 on the multiple transversely arranged profile transfer mechanisms 20 is used to support the profile with a longer length and a maximum weight of 1000 kg; then, under the action of the longitudinal feeding drive 224, the longitudinal feeding active wheel 221, the longitudinal feeding driven wheel 222, and the longitudinal feeding waist-shaped transmission member 223 are driven to rotate synchronously, so that the profile supported on the longitudinal feeding waist-shaped transmission member 223 is conveyed in the direction of the unloading side (longitudinal conveying) until it moves to the set position of the longitudinal feeding frame 22 and stops conveying; then, the linear drive 23 drives the longitudinal feeding frame 22 to descend to the set position as a whole, and the profile to be cut and The transverse feeding rollers 211 on the transverse feeding frame 21 are in contact, and under the action of the transverse feeding driving member 212, multiple transverse feeding rollers 211 rotate synchronously, so that the profile to be cut can be transported toward the direction of the laser cutter (transported to the right side in the transverse direction); the profile after cutting is transported in the direction away from the laser cutter (transported to the left side in the transverse direction), and is also transported to the transverse feeding rollers 211 on the transverse feeding frame 21, and through the reverse rotation of the transverse feeding driving member 212, the profile is gradually transported in the direction away from the laser cutter until it reaches the set position and stops transporting in the transverse direction; then the linear driving member 23 runs again, driving the longitudinal feeding frame 22 as a whole to rise to the set height, and under the action of the longitudinal feeding driving member 224, the profile after cutting continues to be transported in the direction of the unloading side (longitudinal transportation), realizing the loading and unloading of the profile.
