Description
Technical Field
The invention relates to the technical field of wood processing, in particular to a woodworking planing and milling machine capable of planing four sides of a wood blank.
Background
The woodworking planing and milling machine is a woodworking machine for planing and cutting the surface of the wood with rough materials of standard. The woodworking four-side planing and milling machine is mainly used for processing wooden products with specifications such as timber blocks, wood boards, wood floors and the like, and planing the upper surface, the lower surface and the two side surfaces of the timber. According to the habit of the industry, the woodworking planing and milling machine can be divided into four-axis four-side planing, five-axis four-side planing, six-axis four-side planing and other multi-axis four-side planing; the woodworking four-sided planer has high production efficiency and good processing quality, and is high-efficiency and high-quality wood material cleaning processing mechanical equipment.
The five-axis woodworking four-side planer is the most widely applied four-side planer, and the main working parts of the five-axis woodworking four-side planer comprise an upper planer shaft, a lower planer shaft, a planer tool arranged on the planer shaft, a left vertical planer shaft, a right vertical planer shaft, a vertical planer tool arranged on the vertical planer shaft, and a lower planer tool, a right vertical planer tool, a left vertical planer tool, an upper planer tool and a lower planer tool which are sequentially arranged on a timber feeding path. 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 woodworking 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 uniformly 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.
