Description

High-speed optimal cut-off planing production line

technical field

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

Background technique

With the increasing demand for wood resources and the protection of log resources, the wood processing industry is facing higher and higher economic and technical multiple processing requirements, which not only require wood processing production equipment to have higher output material utilization, and requires processing equipment to have a higher degree of automation and lower labor costs.

The wood processing method is generally to first cut the round wood into a board, then cut the board longitudinally into a rod-shaped wood, and then cut it horizontally; Horizontally preferred cut-off saw is used as the horizontal cut-off equipment. After the wood is cut horizontally, it will be transported to the planing and milling equipment (such as double-sided planer, four-sided planer and other woodworking planing and milling machines) to plan and mill the finished product that is smooth, flat and accurate, and meets the required cross-sectional size. material. Finally, according to the technical requirements of wood product assembly, the finished wood is processed into wood products by finger jointing, glue jointing or other splicing methods. In the prior art, the transverse cutting and wood planing of wood are processed separately by independent equipment, and the wood needs to be transported by manpower or other transportation equipment between the transverse cutting saw and the wood planer. , not only consumes a lot of manpower and material resources, but also has low production efficiency, it is difficult to realize automatic assembly line production, and it is also difficult to ensure the processing quality and processing accuracy of finished wood, and there are also hidden dangers to personal and equipment safety.

The transverse optimal cut-off saw is the sawing unit in the cut-off production, which determines whether the transverse optimal saw can efficiently and accurately cut the wood. For the circular saw blade, an upper feeding pressure roller and a lower feeding idler roller are arranged in pairs on both sides of the circular saw blade, and the upper feeding pressing roller and the lower feeding idler roller form a pair of feeding rollers. When the cut-off saw is cut at high speed, the upper feeding pressure roller and the lower feeding roller quickly brake, position, compress, cut, and push the wood according to the instructions of the control system; during the sawing process, the cut-off saw is preferably used for frequent braking and positioning And then push the feeding, the transverse optimal cut-off saw will not only cut off the defective wood, but also carry out combined cutting of different lengths of wood to obtain the maximum yield and use value. Therefore no matter be positioned at the inlet end of preferred cut-off saw front side, or be positioned at the discharge end of preferred cut-off saw rear side, input or output wood material not only has the complex work state such as pause and rapid feed, and its speed also can change with the length of wood material. The movement speed of the wood is always discontinuous and unbalanced, which makes the truncated wood have a large inertial speed and impact force.

At the inlet end of the front side of the cut-off saw, the existing conveying and feeding device allows the wood wool to be cut to be placed on the feeding and feeding table one by one, so as to avoid overlapping, collision, and even jamming of the front and rear wood to be sawed , at the same time, the feeding end of this structure is only provided with a side feeding support on one side, which cannot form effective constraints on both sides of the wood. Processing quality and precision; especially the structure of placing wood to be sawed one by one, not only increases labor and labor intensity, but also has low production efficiency, and is prone to misoperation, making it difficult to ensure consistent sawing quality.

At the discharge end on the rear side of the preferred cut-off saw, the transverse cut-off saw is preferably provided with a cut-off wood conveying frame adjacent to the wood output side, and the wood conveying frame is provided with a feeding table and a conveyor belt for conveying wood, and a conveyor belt holder Supported on the feeding table, the cut wood is transported to the next process through the conveyor belt on the wood conveying frame. Although the conveying device of this structure can realize the output and conveying of wood, it is also easy to cause collisions, overlaps, or even jamming of cut wood during the conveying process, which poses safety hazards for equipment and personnel, and cannot eliminate sawing at the same time. Defective waste generated.

Woodworking planer and milling machine is a woodworking machine for planing and cutting the surface of woolen wood made of specifications. There are mainly four-sided planing and milling machines and double-sided planing and milling machines. Among them, the four-sided planer and milling machine is the most widely used planer and milling machine. Its main working parts include horizontally installed upper and lower planer shafts and planers installed on the planer shaft, and vertically installed left and right vertical knife shafts and installation For the vertical knife on the vertical knife shaft, its planer is followed by the following planer, right vertical knife, left vertical knife, upper planer and lower planer on the wood feed path. For planing wood, the upper and lower planing surfaces of the wood, especially the lower surface fed forward along the workbench, have a significant impact on the processing quality and planing accuracy of the wood, while in the existing four-sided planing and milling machine structure , because before the planing of the left and right sides and the precise planing of the upper and lower surfaces, the lower surface is only planed once with a lower planer, and this plane is the reference plane for subsequent planing steps. The wood reference plane formed by one-time planing is relatively rough, and the planing deviation is large, which leads to inaccurate positioning of subsequent planing, low planing accuracy, and the inability to process clean materials with precise dimensions and small errors.

The feeding end of the existing four-sided planing and milling machine is often only provided with a wood side support plate on one side, and the wood is not restricted in the feeding section, and the wood can only be pushed forward when it enters the upper and lower feeding roller pairs. Feeding, so whether the wood in the existing structure is in the feeding section of the feed roller or in the feeding section of the side stand, the left and right sides of the wood are not restricted, and the wood is prone to feed deviation during the feeding stage. Collision or overlap with front and rear wood advances not only affects the processing quality and precision of the wood, but also affects the planing efficiency, especially in high-speed planing or when the wood is in the planing production line, the unrestricted feeding of such wood cannot form a continuous and smooth It is very easy to produce irregular lines or uneven surfaces on the wood surface, and even safety failures such as material jams.

The feeding mechanism of the planer milling machine also directly affects the precision and quality of wood planing. Only when the feed roller can reliably and continuously grasp the wood can the wood reliably overcome the planing resistance of the planer and move forward evenly and smoothly. For example, the structure of the feeding frame and feeding roller assembly disclosed in the Chinese patent "Fine Double-sided Planer" (patent application number: 201711440790.5) can form a strong clamping and advancing wood during the working process, but with the four-sided planing and milling processing With the continuous improvement of speed and the increase of the length range of wood, especially for short material planing, there is still a large unconstrained space between two adjacent feed rollers. During high-speed planing, this restraint gap cannot be effective. When the wood is effectively pushed by the ground, the jitter of the fed wood will occur, resulting in an unstable feed speed, especially when the length of the wood is less than the distance between the two feeding rollers, it is impossible to ensure that the wood is pushed forward evenly and reliably.

When the wood enters the planing position of the upper planer, the head of the wood tends to be lifted up and tilted, and the phenomenon of multi-cutting at the head end of the wood occurs, forming the so-called "head-gnawing" defect. When the wood enters the normal planing state, the wood will It will also change with the size of the cutting component, and there will be different degrees of random upward elastic warping, forming different degrees of irregular planing ripples on the surface. Therefore, the four-sided planer and milling machine is always equipped with front and rear presser foot components at the front and rear sides of the upper planer. In order to improve the pressing and restraint effect of the presser foot, the front and rear presser feet should always extend as far as possible into the cutting position of the upper planer. This is inevitable. The unrestricted area between the presser foot and the adjacent feed roller is increased, and when the four-sided planer milling machine runs at high speed or processes short materials, it cannot guarantee reliable compression and effective advancement of wood.

A wood guide channel is formed between the corresponding guide chain and the guide side vertical roller, and the wood guide channel is connected with the wood feed channel.

In the above structure, since it is preferable that the cut-off saw and the planer are connected by a cut-off material conveying device, and the feed end of the cut-off saw is preferably connected with a feed conveying device, thus forming a preferred cut-off and planing milling machine. In the whole process production line, it is no longer necessary to use manpower or other transportation equipment to carry out the transfer between the preferred cut-off saw and wood planing and milling process of wood, which not only saves a lot of manpower and material resources, but also can realize automatic assembly line production conveniently, with low production efficiency and It is easy to ensure the processing quality and processing accuracy of finished wood, and eliminate the hidden dangers of personal and equipment safety. A sorting pusher is provided on the cut-off material conveying device. When the cut-off material conveying device conveys the recyclable material to the corresponding position of the sorting pusher, the sorting pusher will The material is pushed away from the cut-off material conveying device to realize the automatic sorting of cut-off wood, which improves the automation degree and production efficiency of wood sorting.

Since the side pressure wheel is provided at the position corresponding to the feeding side support plate of the feeding conveying device, and a feeding channel is formed between the feed side support plate and the feed side pressure wheel, when the cut wood enters the cutting saw stage , the wood is accurately and stably pushed to the center of the feeding roller pair composed of upper and lower feeding rollers under the clamping of the side pressure wheel and the feeding side plate, so that the wood is reliably clamped and restrained on the left, right and up and down, realizing Reliable control of the wood pushing speed enables the wood to accurately realize stop positioning, fast cutting and advancing feeding according to the optimal cutting command, not only can achieve accurate fixed-length cutting of the wood, but also completely avoid deviation and stacking of the wood feeding , which not only effectively guarantees the cutting quality and dimensional accuracy, but also facilitates the efficient and high-speed operation of the cutting saw, which greatly improves the production efficiency of the cutting saw and ensures the safe and stable operation of the cutting saw. Also because the side pressure swing arm that supports the side pressure wheel is supported with a side pressure spring, the elastic force of the side pressure spring is applied to the side pressure wheel through the side pressure swing arm, and the side pressure wheel is pressed by the elastic force of the side pressure spring. , not only the pressure is stable, it is less affected by the use environment, the compaction and restraint effect on wood is reliable, and it is easy to adjust and control according to different processing objects to obtain reliable compaction force. Also because the material control baffle is installed on the workbench, the gap between the material control baffle and the feeding conveyor belt and the thickness ratio of the conveyed wood are controlled between 1.8-1.2. First, the setting of the material control baffle makes the wood to be cut only It can feed and feed to the cut-off saw one by one, and the setting of the gap size ensures that the wood to be cut is pushed forward one by one, so that the wood storage bin to be cut can be established on the working table, which can not only greatly save labor and labor intensity, but also more It is beneficial to realize automatic control of feeding and feeding, greatly improves production efficiency, and is more suitable for high-efficiency, high-speed operation and production of cut-off saws.

Due to the cut-off material conveying device, two conveyor belts, the front conveyor belt and the rear conveyor belt, are arranged on the conveyor frame, and a pick-up roller is arranged between the front conveyor belt and the rear conveyor belt. After passing through the front conveyor belt, and then through the pick roller, it enters the rear conveyor belt. In this way, the gap distance between the front conveyor belt and the pick roller can be adjusted so that the cut waste on the front conveyor belt touches the pick roller. , and falls along the distance between the conveyor belt and the rejecting roller, and no longer enters the rear conveyor belt, so as to realize the automatic removal of the cut waste, the removal action is accurate, and the structure is reasonable and exquisite. And because there is a material control baffle above the rejecting roller, only a certain amount and thickness of wood is allowed to pass through and sent to the rear conveyor belt under the gap control of the material control baffle, so that the cut wood can only be cut one by one. Through the space channel between the material control baffle and the picking roller, the mutual collision and head-to-tail overlapping between adjacent woods are effectively avoided, so that the wood can enter the next process in an orderly manner. When the wood enters the rear conveyor belt, the control switch above the rear conveyor belt can sense and control the passing quantity and thickness of the wood. When the wood is stacked on top of each other and the thickness increases, the control switch sends an instruction to stop the conveyor belt. Work, and then start normal operation after the abnormality is dealt with. This structure eliminates the occurrence of abnormal wood transportation through the dual control of machinery and electrical appliances, ensures accurate, reliable and smooth transportation of wood, and completely avoids the occurrence of equipment and personnel safety failures. Also because adjustable front section movable backboard and rear section movable backboard are provided with the corresponding positions of the front section conveyor belt and the rear section conveyor belt, the movable backboard of the front section, the back section movable backboard and the fixed feeding backboard have formed a In the wood conveying channel, under the clamping and restraint of the fixed backing board and the movable backing board, the wood enters the next process with a certain conveying direction and path, which not only effectively prevents the deviation and stacking of the wood conveying, but also ensures that the wood Processing quality and processing accuracy.

Since the rough planer lower planer, the fine planer lower planer and the upper planer on the planer and milling machine body are arranged sequentially from front to back along the wood feed channel, when the planer milling machine is working, firstly use the rough planer lower planer to rough plan and mill the lower surface of the wood. After rough planing and milling, the lower surface is finely planed, so that the lower surface of the wood forms a precise planing reference plane for the planing and milling of the two sides and the upper surface. The design and structure of this planing milling cutter Sequential arrangement ensures the fine and accurate processing of wood, not only high planing processing efficiency, but also high planing precision, small processing deviation and excellent quality, which can effectively meet the high-quality and efficient production requirements of wood processing. And because the follow-up cylinder and the follow-up roller frame hinged with the follow-up cylinder are added on the beam of the feeding frame, the follow-up roller frame is rotatably supported with follow-up rollers, and the follow-up rollers are located on the adjacent two feeders. Between the rollers, the compaction control of wood between two adjacent feeding rollers is added, which can more effectively realize the continuous advance control of planed wood and ensure the stable feeding of rough and fine planed materials. This structure is especially suitable for short materials. The advanced planing process enables the short material to be pushed forward reliably during planing, and the phenomenon of "gnawing the head" and "tail" of short material processing will not appear, which ensures the fine planing and milling of short material. Also because there is a presser foot follow-up roller sliding seat on the front presser foot seat, and a presser foot follow-up roller is supported by the rotation of the lower end of the presser foot follow-up roller slide seat, so planing wood before entering the planing process of the planer, Restricted by the front pressing claw and the presser foot follow-up roller on the front side of the front pressing claw, this structure forms a more reliable control and full-range pressing constraint on the planed wood, avoiding the pressure on the front side of the front pressing claw. The out-of-control state of wood in the area is not only more suitable for high-speed continuous planing processing of wood, but also more effective in controlling wood compaction, effectively avoiding the phenomenon of "head gnawing" in wood processing, and can effectively compress short wood. Tight control allows the planer to plan a wider range of wood lengths. Furthermore, because a wood guide device is installed at the front end of the fuselage, the wood guide device and the wood guide side vertical roller form a wood guide channel. Under the clamping of the roller, it accurately enters the center of the clamping and advancing roller pair composed of the upper and lower feeding rollers, so that the wood is stably clamped and restrained in the left, right, up and down, and the wood guide device and the vertical roller on the guide side are on the wood. The effective clamping and feeding of the material completely avoids the deviation of the wood feeding and the mutual collision during the advancing process and the stacking of the front and rear material ends. The efficient and high-speed planing of the milling machine greatly improves the production efficiency of the milling machine and ensures the safe and stable operation of the milling machine.
