Automatic plate grooving device and plate grooving machining method thereof

Abstract

The invention provides a full-automatic plate grooving device and a plate grooving machining method thereof. The full-automatic plate grooving device comprises a workbench, a grooving assembly and a PLC control system, the workbench is provided with a conveying assembly, a first driving device and a positioning module, the grooving assembly comprises a groove saw portal frame, a second driving device and a saw blade, and the second driving device at least can drive the saw blade to move. The PLC control system controls the first driving device, the second driving device and the positioning module to realize full-automatic grooving of the plate. The technical scheme is suitable for plate grooving with low bonding strength, the depth and the width of a groove are adjustable, liquid does notneed to be used for cooling the saw blade in the grooving process, and the full-automatic accurate grooving of the plate can be realized fast.

Description

technical field [0001] The invention relates to the manufacturing field of wood processing, in particular, to an automatic and precise grooving device for slabs and a processing method for slotting slabs. Background technique [0002] At present, the commonly used wood-based panels are mostly particleboard, fiberboard, plywood and laminated wood, etc. The above-mentioned wood-based panels are based on particle, fiber and veneer as basic units, and are made by applying adhesive and pressing at high temperature and high pressure. The finished board has a high density. , the production cost is low, but there are also many defects: the product is heavy, and it is inconvenient to handle; the structural strength of the finished board is low; the resistance to static bending deformation is poor; Production requirements. To this end, the patent (CN201710542859.9) designs a core for high-strength wooden boards, the structure of which adopts the units in the transverse bearing body, ...

AI Technical Summary

Problems solved by technology

[0002] At present, the commonly used wood-based panels are mostly particle boards, fiberboards, plywood, and laminated materials. The above-mentioned wood-based panels are based on shavings, fibers, and veneers, etc., and are formed by pressing high temperature and high pressure with adhesives. , the production cost is low, but there are also many defects: the product is heavy and inconvenient to carry; the finished board has low structural strength; Production requirements

Therefore, it cannot complete the grooving work of the entire slab at one time

When multiple slots need to be opened, as the number of slots increases, such as using the patented (CN105500479B) equipment, the number of slots can be adjusted by adjusting the number of saw blades, and more saw blades are used to slot at the same time. The resistance of the entire plate increases, and the friction of the plate will also increase accordingly. Since the plate is bonded by slats with the same width and thickness, the force on the joint surface between the slats is low. When a large number of saw blades make multiple grooves, because the sawing object is anisotropic wood or heterogeneous composite materials, the saw blades are high-speed sawing, if not precisely controlled, the saw blade will not only reduce the saw Cutting accuracy, causing severe vibration and noise of the saw blade, which causes the plate along ( figure 1 As described in b) the position in the direction A falls off, and in severe cases, it will cause the slot of the plate to tear

When the plate is produced and processed, the groove depth is adjusted according to the needs of the product. The depth of the grooves on the plate can be the same or different, but the groove depth cannot be adjusted in the prior art

In addition, during the grooving process of the wood board, the saw blade will generate a lot of heat, which will cause the temperature of the saw blade to rise. The life of the saw blade is short and the cost increases. At the same time, the flying of sawdust causes serious pollution to the working environment

In the prior art, there is also a method of directly pouring cooling liquid on the saw blade for the log multi-blade sawing machine. In this way, the amount of cooling liquid is large, and a large amount of cooling liquid is not really used to lower the saw blade. In terms of temperature, it is more difficult to clean the machine

The patent (CN201519997U) loads a water spray device in the shaft of the log multi-blade saw cutting machine. Although it has a good cooling effect, it still needs to consume a lot of water, and the subsequent wastewater needs to be treated. Undoubtedly increased production costs
