Plate blank cut-off device

Abstract

The invention discloses a plate blank cut-off device, and relates to the technical field of plywood plate blank assembling and paving. The plate blank cut-off device comprises a cut-off platform and asawing device, a linear sliding unit support is connected to the bottom of the cut-off platform, a sliding rail is arranged on the top of the linear sliding unit support, and a gear rack is arrangedat the bottom of the linear sliding unit support; a sliding block is installed on the sliding rail and connected with the sawing device, a feeding motor is installed on the sawing device, and a gear meshing with the gear rack is connected to the feeding motor; a sawing motor is installed on the sawing device and connected with a belt wheel through a conveying belt, the belt wheel is installed at one end of a sawing shaft, and a saw blade is installed at the other end of the sawing shaft; and a rack is arranged above the cut-off platform, first air cylinders are arranged on the rack, and a pressing plate is connected to the lower ends of the first air cylinders. According to the plate blank cut-off device, the cut-off step in the plate blank cut-off process achieves mechanical automation, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of laying plywood slabs, in particular to a slab cutting device. Background technique [0002] my country's wood-based panel industry has developed rapidly, and its total output ranks first in the world, while plywood accounts for more than 50% of the total wood-based panel output. The plywood production areas are mainly concentrated in Jiangsu, Zhejiang, Hebei, Guangdong, Shanghai, Fujian and other economically developed and natural A province that is not rich in forest resources. Since the 1990s, my country has gradually developed into the largest plywood production country in the world. According to the statistics of the National Forestry and Grassland Bureau, the national plywood production in 2018 was 178.98 million m 3 . At present, the number of large-scale plywood production enterprises in my country has increased, and the average production scale has reached 5000-7000m 3 , the number of registered ...

Problems solved by technology

[0003] For small-diameter wood, it is necessary to use a small rotary cutter for rotary cutting. The veneer cut by rotary cutting is small in size. When plywood is produced by traditional technology, the veneers are stacked together after being glued, and then transported to the billet forming table. Laying one by one, this method of billet assembly requires a lot of labor, low production efficiency and high production cost
