Description

Technical Field

[0001] The utility model belongs to the field of woodworking equipment, in particular to an automatic feeding device for a lathe. Background Art

[0002] A veneer lathe is a device used to process wood segments of a certain length and diameter into continuous veneer strips for the production of plywood, blockboard and other man-made board veneers.

[0003] Wooden tableware such as sanitary chopsticks, knives, forks and spoons, and ice cream sticks can also be produced by lathes, which have the advantages of fast cutting speed and less waste output.

[0004] The wood segments are typically steamed at high temperatures before being loaded onto the lathe. Currently, lathe loading is still performed by the operator holding the wood segments flat with both hands and clamping them onto the lathe's clamping head. This is labor-intensive and dangerous, leading to frequent injuries. Furthermore, the lathe struggles to center the wood segments, and eccentric loading of the wood segments results in a large amount of chipped boards during peeling, wasting precious wood resources. Lathe loading equipment for wood segments has also been developed. Despite decades of development, existing lathe loading equipment is not only slow but also takes up space for operators to change and sharpen knives, making it a poor replacement for manual loading.
