Batten pre-connection assembly for wood-processing machine

Abstract

The invention relates to a batten pre-connection assembly for a wood-processing machine. The batten pre-connection assembly comprises a differential connection mechanism and a connection flattening mechanism. The differential connection mechanism comprises an upper differential connection assembly, a lower differential connection assembly and a connection driving motor; the upper differential connection assembly and the lower differential connection assembly correspond in the up-down direction; the upper differential connection assembly comprises upper connection pushing wheels, the connectiondriving motor drives the upper connection pushing wheels to rotate, and the rotating speeds of the upper connection pushing wheels are sequentially decreased in the connection conveying direction a;and the lower differential connection assembly comprises lower connection pushing wheels, the connection driving motor drives the lower connection pushing wheels to rotate, and the rotating speeds ofthe lower connection pushing wheels are sequentially decreased in the connection conveying direction a. The connection flattening mechanism comprises an upper flattening assembly and a lower flattening assembly; the upper flattening assembly is composed of a plurality of upper flattening units, and the lower flattening assembly is composed of a plurality of lower flattening units; and the upper flattening units and / or the lower flattening units are arranged in an elastic floating mode. The batten pre-connection assembly structure is precise in connection, short in connection travel and high inconnection efficiency.

Description

technical field [0001] The invention relates to a wood processing machine, in particular to a wood strip pre-splicing assembly for a wood processing machine. Background technique [0002] There is a splicing process in the production process of splints. The traditional splicing method is to use the corresponding equipment to touch the two splints in opposite directions to realize the splicing, or, one splint is positioned and fixed, and the other splint is connected to the other. The wooden strips with fixed positioning are moved and touched to achieve connection. The above two methods are violent connection methods. When two wooden strips are connected by the above two methods, it is easy to damage the connecting teeth on the wooden strips, which directly affects the connection effect. Reduce the yield; in addition, because the splicing process is completed separately on the corresponding equipment, it will cause troublesome operation, high input cost, and long length of wo...

[0002] There is a splicing process in the production process of splints. The traditional splicing method is to use the corresponding equipment to touch the two splints in opposite directions to realize the splicing, or one splint is positioned and fixed, and the other splint is connected to the other. The wooden strips with fixed positioning are moved and touched to realize the connection. The above two methods are violent connection methods. When the two wooden strips are connected by the above two methods, it is easy to damage the connecting teeth on the wooden strips, which directly affects the connection effect. Reduce the yield; in addition, because the splicing process is completed separately on the corresponding equipment, it will cause troublesome operation, high input cost, and long length of wooden strips. The traditional splicing method will lead to a long transmission stroke and the whole set of wood The size of the processing machine is large

In addition, in order to improve the splicing quality of wooden splicing and avoid excessive height difference at the splicing point, the existing splicing equipment for wooden splicing is generally equipped with a flattening mechanism, but the traditional flattening mechanism uses the upper and lower rollers to approach each other The wooden strips are flattened in the same way, and the pressure of each roller on the wooden strips is consistent and cannot be adjusted. When two wooden strips with different thicknesses are connected, because the upper and lower rollers are respectively set on the upper and lower levels, it is impossible to flatten two thick wooden strips at the same time. , thus affecting the connection effect of wooden strips; in addition, for products with a large drop at the connection point, in the leveling process, the leveling amount increases, resulting in waste of raw materials and increased workload
