Automatic shearing machine for pine branches of plastic Christmas tree

Abstract

The invention discloses an automatic shearing machine for pine branches of a plastic Christmas tree. The automatic shearing machine comprises a rack, a feeding mechanism, a material pulling mechanism, a material cutting mechanism and a control circuit, wherein the feeding mechanism, the material pulling mechanism and the material cutting mechanism are arranged on the rack; the material cutting mechanism comprises a movable knife and a fixed knife; the feeding mechanism is arranged behind the material cutting mechanism along the longitudinal direction of the rack; the material pulling mechanism is arranged in front of the material cutting mechanism; the feeding mechanism presses the pine branches to feed forwards; after stems of front-end pine branches penetrate through a gap between the movable knife and the fixed knife, a chuck of the material pulling mechanism clamps the stems of front-end pine branches and pulls the pine branches to move forwards; when a detection device of the control circuit detects that heads of the front-end pine branches support against blade parts of the movable knife and the fixed knife, the pine branches are cut off by the material cutting mechanism. According to the automatic shearing machine disclosed by the invention, automatic shearing of the pine branches can be realized, and high shearing efficiency is realized; the shearing is performed according to the detected position of the heads of the pine branches, so that the shearing quality is high, and the requirements of large-batch and automatic production of the pine branches can be met.

Description

[technical field] [0001] The invention relates to an artificial Christmas tree, in particular to an automatic cutting machine for plastic Christmas tree pine sticks. [Background technique] [0002] The Christmas tree is an indispensable decoration when celebrating Christmas in Western countries. An artificial Christmas tree refers to a Christmas tree made artificially compared to a naturally cultivated Christmas tree. Its production method is to wind the cut leaf material on the iron wire to make pine branches, and then tie them to the main branch frame to form a tree body. [0003] The main part of the artificial pine branch is composed of PVC-wrapped iron wire, and the branches and leaves are cut from PVC film. It is V-shaped. In the production process of artificial pine branches, the first thing to do is to make pine sticks. There are dozens of pine branches on a pine stick with a length of several meters or more than ten meters. It needs to be cut to become a pine bra...

AI Technical Summary

Problems solved by technology

The needles of dozens of pine branches on the pine bar are cut, and the back of the pine branch is a stem without needles, but the lengths of pine branches of different specifications, including dozens of pine branches on a pine bar, are different. The automatic cutting of equipment increases the difficulty; the efficiency of manual cutting is very low and cannot meet the needs of mass production
