A rapid pressing vertical veneer continuous splicing machine and its splicing process

Abstract

The invention discloses a vertical veneer continuous assembling machine capable of realizing rapid press-fitting and an assembling technology of the machine. The machine comprises a working table, a veneer bevel grinding mechanism, a gluing mechanism, a turning mechanism, an abut-jointing mechanism and a hot-press forming mechanism, wherein the veneer bevel grinding mechanism is arranged at the upper part of the working table and comprises a support, a transmission shaft, carrying rollers, carrying and conveying belts, pressing rollers, clamping belts and a bevel grinding machine; the gluing mechanism is arranged on one side of the veneer bevel grinding mechanism; the turning mechanism is arranged on one side of the gluing mechanism; the abut-jointing mechanism is arranged on one side of the turning mechanism; and the hot-press forming mechanism is arranged on one side of the abut-jointing mechanism and comprises hot-press blocks, hot-press conveying belts and rollers, the hot-press conveying belts are arranged on the rollers, a plurality of hot-press blocks are arranged on the hot-press conveying belts, and the distance between every two hot-press blocks is consistent with the length of a slab. With the machine and the technology, bevel-ground bevels are uniform and smooth in the bevel grinding process of veneer, the strength of joints of the assembled veneer is guaranteed, and use of the plywood veneer is met.

Description

technical field [0001] The invention belongs to the technical field of veneer processing machinery, and in particular relates to a fast-pressing vertical veneer continuous splicing machine and a splicing process thereof. Background technique [0002] With the development of the economy, people have higher and higher requirements for housing and furniture decoration materials, and the demand for wood is increasing. In the traditional wood processing industry, pure wood boards are usually used as building decoration materials. The part of the tree that can be processed into lumber is limited, resulting in a low utilization rate of the tree. [0003] The emergence of wood plywood solves the problem of low utilization rate of pure wood boards processed from trees. Its structure is made of thin wood layers after gluing, drying, and pressing. The disadvantages are that the process is complicated and the cost is high, and it is not suitable for large-scale production; The raw mate...

Problems solved by technology

[0002] With the development of the economy, people have higher and higher requirements for housing and furniture decoration materials, and the demand for wood is increasing. In the traditional wood processing industry, pure wood boards are usually used as building decoration materials. The part of the tree that can be processed into lumber is limited, resulting in low utilization of the tree

[0003] The emergence of wood plywood solves the problem of low utilization rate of pure wood boards processed from trees. Its structure is made of thin wood layers after gluing, drying, and pressing. The disadvantages are that the process is complicated and the cost is high, and it is not suitable for large-scale production; The raw material veneers used in plywood production need to be obliquely ground and spliced ​​before use to form larger spliced ​​veneers, which are used as the first layer of plywood panels; because traditional veneer oblique grinding and splicing are two independent processes, separate It is carried out and all work on the ground, which has the disadvantages of large floor area, high labor cost, inability to achieve continuous production, and low production efficiency

[0004] After retrieval, the authorized announcement number CN 202846636 U is a double-layer continuous veneer oblique grinding and splicing equipment, including a transport mechanism. An inclined grinding machine and at least one splicing machine are sequentially arranged along the transport direction of the transport mechanism. The discharge end of the mill and the feed end of the splicing machine are respectively connected to the transport mechanism through a belt conveyor. This equipment can obliquely grind and splice the eucalyptus veneer, which is the raw material for plywood production, to form a larger format. Splicing veneers; however, during the oblique grinding process of the veneer, the oblique grinding of the veneer is prone to warping. During the grinding process, the inclined surface of the oblique grinding is uneven and rough, so that the thickness of the joints of the subsequent jigsaw panels is uneven, the strength of the veneer is low, and it is easy to break, and the subsequent process cannot be carried out, which cannot meet the use of plywood veneer
