Description

Wrapping machine for roll trap {WRAPPING DEVICE FOR ROLLTRAP}

The present invention relates to a lapping machine for roll traps, and more particularly, to a lapping machine for roll traps that wraps and rolls a roll trap used for controlling pests of trees.

Insects generally refer to insects that damage trees. These pests mainly damage trees when they are active from spring to autumn. Pests vary according to the climate and occur differently depending on distances from houses or factories, topography or other environmental factors.

Until the mid-1970s, four pests in the forest, including four species of pests including pine moth, pine needles fly, American butterfly moth, alder leaf beetle, and pine rust, became a major problem. The damage from pine needles was continuously spreading, and new pests such as pine bark beetle, pine needle bees, pyrus beetle, and plane beetle insects appeared. In particular, oak wilting disease has become a major problem due to the activity of photonic long beetle, a pest that mediates the formation of fungi in trees, and also by absorbing water from trees such as vines, weighted trees, cedar trees and plane trees. The problem of damaging flower cicada is emerging rapidly.

In the above-described photonic long-wood tree, males penetrate through the trunks of oaks, seo trees and the like, and attract the females into the puncture space by attracting a group (female, male) with male pheromones. In addition, Raffaelea genus Ambrosia bacteria in the fungus, such as females of the photonic long-habited tree tree, are transmitted to the inside of the tree to destroy the tree's conduit and the like. In addition, the above-mentioned flower cicada strongly adheres to the lost water such as the vine to suck the sap. Therefore, forests and horticultural farms are severely damaged by the algae and the cicada.

Insects that penetrate into the tree's husk (bark) can be used to predict infection through the accumulation of sawdust-like dung and tree dust at the base of the tree, and in the case of pests that add leaves, the leaves are partially absent or discolored. The infection can be predicted by the color of the insect, and for certain pests, the pheromones secreted by the female can be used to predict the infection.

Here, as described above, the ambrosia pest that produces the fungus in the tree penetrates through the tree trunk of the tree corresponding to the height of about 1.5 m (the specific tree is higher than this) from the bottom of the tree to invade the tree's conduit. Infarct. In addition, the above-mentioned absorptive pest adheres to the outer shell of the liver and absorbs the sap, thereby obstructing the flow of the sap. Thus, trees are eventually killed by these pests.

On the other hand, in order to conveniently combat such perforated pests, recently, a film-type roll trap coated with a viscous adhesive and a sticky repellent liquid on both sides is wrapped on the trees to cover the pests while shielding the outer skin of the trees. A way to do it has been developed.

Therefore, it is not easy to wind the roll trap 2, and there is an inconvenience that an operator frequently misses the bobbin 3.

In addition, if the worker misses the bobbin 3, the roll trap 2 wound around the tree 1 is not only released, but also the roll trap 2 wound around the bobbin 3 is also released, and the roll trap 2 is bonded to the adhesive layer. (2b) and the killing layer (2c) is contaminated by foreign matters have a disadvantage that does not function.

In addition, the worker wraps the roll trap 2 to the tree 1 to a certain height, and then cuts it with a tool such as a knife or scissors. In this case, the tool is supported by the other hand while supporting the roll trap 2 with one hand.
