Description

Technical Field

[0002] As a core piece of equipment in the woodworking industry, splicing machines are mainly used to splice standard strips of raw materials such as small-diameter logs, rotary-cut wood cores, and lumber veneers into high-strength solid core boards through processes such as gluing, pressing, and heating. This significantly improves material utilization and production efficiency in the production of plywood, engineered wood, and furniture boards.

[0003] Taking the multi-layer synchronous extrusion wood splicing machine with application number CN202420678526.4 as an example, this equipment innovatively adopts multi-station synchronous extrusion technology, which can realize single-filling dual-station operation, effectively reduce the frequency of manual feeding, reduce the intensity of operation, and greatly improve the efficiency of equipment use.

[0004] However, there is still room for improvement in this equipment: First, the traditional splicing method that relies solely on the pressure of the clamping plate has limitations in terms of splicing accuracy and bonding strength; Second, the fixed design of the slide rod stroke of the second fixed rod results in a narrow range of board specifications that the equipment can adapt to; Third, although the inclined collection trough facilitates the discharge of debris, it is easy to cause the boards to slip and scratch after splicing, and the accumulation of debris requires frequent cleaning and maintenance.

[0005] Based on this, this solution proposes "a panel splicing machine for wood processing" to solve the above problems. Utility Model Content
