Description

High-speed optimized cutting and finish planing production line

Technical Field

The invention relates to the technical field of wood processing, in particular to production line equipment capable of conducting preferential cutting and planing, milling and cutting processing on wood.

Background

With the increasing demand for wood resources and the protection of log resources, the wood processing industry is faced with increasingly higher economic and technical multiple processing requirements, which not only requires higher utilization of wood processing production equipment, but also requires higher automation and lower labor cost.

The wood processing method generally comprises the steps of firstly cutting round logs into boards, then longitudinally cutting the boards into rod-shaped timber, and then transversely cutting the timber; in order to improve the wood resources saving and the wood utilization rate and the wood yield, a transverse preferable cutoff saw is used as transverse cutoff equipment at present, and the wood is transported to planing and milling equipment (such as a woodworking planing and milling machine with double-sided planing, four-sided planing and the like) to be planed and milled to be smooth and flat, and the size is accurate, so that the finished product wood with the required section size is achieved. Finally, the finished product wood is processed into the wood product by finger joint, cementing or other splicing modes according to the technical requirement of wood product assembly. In the prior art, the transverse preferential cutting of wood and the planing and milling of wood are respectively processed by independent equipment, and the wood is carried and transferred by manpower or other transportation equipment between the transverse preferential cutting saw and the wood planing and milling machine, so that a large amount of manpower and material resources are consumed, the production efficiency is low, the automatic assembly line production is difficult to realize, the processing quality and the processing precision of the finished wood are difficult to ensure, and the potential safety hazards of personnel and equipment exist.

The transverse preferential cutoff saw is a sawing unit in cutoff production, and determines whether the transverse preferential saw can effectively and accurately conduct preferential sawing on wood, and comprises a cutoff saw frame and a circular saw blade capable of swinging up and down to realize transverse cutting, wherein an upper feeding press roller and a lower feeding carrier roller are arranged on two sides of the circular saw blade in pairs, and the upper feeding press roller and the lower feeding carrier roller form a feeding roller pair. When the cutting saw cuts at a high speed, the upper feeding press roller and the lower feeding carrier roller rapidly perform braking positioning, compaction, cutting and re-propelling on timber according to the instruction of the control system; the cutting saw is preferably frequently braked and positioned and pushed to feed materials in the sawing process, and the transverse cutting saw is preferably used for cutting defective timber and cutting the timber with different lengths in a combined mode to obtain maximum yield and use value. Therefore, whether the wood is positioned at the inlet end of the front side of the preferential cutting saw or at the discharge end of the rear side of the preferential cutting saw, the input or output wood not only has complex working states such as pause and rapid feeding, but also has the speed which can be changed along with the length of the wood, and the wood movement speed is always discontinuous and unbalanced, so that the cut wood has larger inertia speed and impact force.

At the inlet end of the front side of the preferential cutting saw, the existing conveying and feeding device enables wood blanks to be cut to be placed on a feeding and feeding workbench one by one, so that the wood blanks to be cut are prevented from being overlapped and collided with each other and even clamped and sawn, meanwhile, the feeding end of the structure is only provided with a laterally standing feeding backup plate at one side, effective constraint cannot be formed on two sides of the wood, feeding deviation of the wood is easily generated in the feeding and feeding stage, and the processing quality and precision of the wood are affected; especially, the structure for placing timber to be sawn one by one not only increases labor and labor intensity and has low production efficiency, but also is easy to form misoperation and is difficult to ensure consistent sawing quality.

At the discharge end of the rear side of the preferential cutting saw, the transverse preferential cutting saw is adjacently provided with a cutting timber conveying frame at the timber output side, the timber conveying frame is provided with a feeding working table surface and a conveying belt for conveying timber, the conveying belt is supported on the feeding working table surface, and cutting timber is conveyed to the next working procedure through the conveying belt on the timber conveying frame. The conveying device with the structure can realize output and conveying of timber, but is easy to generate mutual collision and overlapping among cut timber in the conveying process, even a saw is clamped, potential safety hazards of equipment and personnel exist, and defect waste generated by sawing cannot be removed.

The woodworking planing and milling machine is a woodworking machine for planing and cutting the surface of the wood with the finished rough material, and mainly comprises a four-side planing and milling machine and a double-side planing and milling machine. The four-side planer is the most widely used planer, and the main working parts comprise an upper planer shaft, a lower planer shaft, a planer tool, a left vertical cutter shaft, a right vertical cutter shaft, a vertical cutter, a lower planer tool, a right vertical cutter, a left vertical cutter, an upper planer tool and a lower planer tool, wherein the upper planer tool and the lower planer tool are horizontally arranged, the planer tool is arranged on the planer tool shafts, the left vertical cutter shaft, the right vertical cutter shaft and the vertical cutter are vertically arranged, and the planer tool is arranged on the vertical cutter shafts. In the prior four-side planing machine structure, the lower surface is only one lower planing tool for one-time planing before the right and left planing and the accurate planing of the upper and lower surfaces are carried out, and the plane is the reference plane of the subsequent planing step, and the reference plane of the timber formed by one-time planing is relatively rough, so that the planing deviation is larger, the positioning inaccuracy of the subsequent planing is brought, the planing precision is low, and the standard net material with accurate size and small error cannot be processed.

The feeding end of the existing four-side planing and milling machine is often only provided with a timber side backup plate at one side, timber is not limited by advance in a feeding section, and timber can be pushed forward and fed only when entering an upper feeding roller pair and a lower feeding roller pair, so that timber in the existing structure is not limited whether the timber is in a feeding roller feeding section or in a side backup plate feeding section, the timber is easy to generate feeding deviation and front and rear timber pushing collision or overlapping in the feeding and feeding stage, the processing quality and precision of the timber are affected, the planing efficiency is affected, the timber feeding is not limited, continuous and smooth pushing and feeding cannot be formed, irregular lines or surface irregularities are easily generated on the surface of the timber, and even safety faults such as clamping occur.

The feeding mechanism of the planing and milling machine also directly influences the planing precision and quality of the timber, and only the feeding roller can reliably and continuously grasp the timber, the timber can be ensured to be reliably pushed forward evenly and stably against the planing resistance of the planing tool. As disclosed in the chinese patent "fine double-sided wood planing machine" (patent application number: 201711440790.5), the feeding frame and the feeding roller assembly structure can form a strong clamping and pushing force on the wood in the working process, but as the four-sided planing and milling speed is continuously improved, and the length range of the wood is enlarged, especially the short material planing is performed, a larger irreducible space still exists between two adjacent feeding rollers, and during high-speed planing, the constraint space cannot effectively push the wood, so that the shaking of the fed wood can occur, the feeding speed is unstable, and especially when the length of the wood is smaller than the interval between two feeding rollers, the uniform and reliable forward pushing of the wood cannot be ensured.

When the timber enters the planing position of the upper planing tool, the head of the timber tends to lift up and tilt, the phenomenon of multiple cutting of the head end of the timber occurs, so-called head gnawing defect is formed, when the timber enters a normal planing state, the timber also changes along with the size of the cutting component, and the timber is elastically warped upwards at random with different degrees, so that irregular surface planing waves with different degrees are formed. Therefore, the four-side milling machine is always provided with the front and rear presser foot assemblies at the front and rear side positions of the upper plane cutter, and in order to improve the compression constraint function of the presser feet, the front and rear presser feet always extend into the cutting position of the upper plane cutter as much as possible, so that the unconstrained area between the presser feet and the adjacent feeding rollers is necessarily enlarged, and the reliable compression constraint and effective pushing of timber cannot be ensured when the four-side milling machine runs at high speed or processes short materials.
