Background

Wood shavings machine is mainly used for mass production of thin flakes of uniform thickness. The flake shavings are generally used as raw materials of the shaving board, and compared with the traditional particle board, the shaving board has higher strength and better wear resistance due to the fact that the fibrous tissues of part of raw wood are reserved.

At present, wood shavings are generally obtained by shaving logs or broken wood by shaving equipment, the logs are generally cut into fixed sizes in the cutting process, and the size specification of the logs is 1.4, 2.8 and 3.2m for convenient transportation and later adaptation to different processing designs or processing requirements. The log planing mode comprises a mode of reciprocating planing along the axis direction of the log and a mode of adopting drum-type transverse planing; the horizontal reciprocating cutting processing mode is adopted, and although the processing mode can be suitable for logs with all specifications and sizes and processed shavings are relatively long, only one wood can be processed at a time, the processing efficiency is low, and for example, a multi-layer wood shaving device is disclosed in patent publication No. CN 113524374A. The roller type planing mode is adopted to adapt to simultaneous planing of a plurality of woods, and the processing efficiency is obviously improved. For example, the patent with publication number of CN106476105A discloses a novel wood shaving machine, adopts a rotary cutter cylinder full-circumference wood cutting mode, and can circumferentially encircle a large amount of wood for simultaneous cutting at one time, thereby effectively increasing the contact cutting area of the wood, and greatly improving the wood processing efficiency. In addition, the structural design of cage type internal cutting is adopted in the scheme, so that the log or wood put into the rotary cutter barrel cannot be excessively long and excessively large, the main reasons are that the structure is limited, the excessively long wood is easy to collide with the rotary cutter barrel in the rotating process of the rotary cutter barrel to cause internal cutter deformation, and meanwhile, the whole rotary cutter cage is excessively large in vibration due to the fact that the gravity center of the rotary cutter cage is sunk. Meanwhile, due to the limitation of the processing mode and the structural size of the rotary cutter barrel, the equipment cannot process a plurality of logs at the same time, and is difficult to meet the requirement of large-scale shaving board processing.

In fact, through the above-mentioned linkage structure, the swing angle of the swing arm 231 can be synchronously adjusted by the pressing device 240 when the logs are stacked, so that the planing range of the knife roller 232 can be controlled. The buffer 256 is a spring in the present application, and has a main function of absorbing vibrations during planing of the cutter roller 232 and preventing the vibrations from being transmitted to the pressing device 240, in addition to the delayed action of the sliding block 252.

Referring to fig. 5 and 7, in order to implement the above-mentioned design of stacking the logs and driving the swing arm 231 at the same time, the pressing device 240 includes a mounting frame 241, a plurality of elastic pressing units and a pressing telescopic device 242, the mounting frame 241 is mounted on the upper area of the housing channel 211 of the frame 210, a plurality of pressing slots 243 are provided on the mounting frame 241, a plurality of elastic pressing units are slidably mounted in the pressing slots 243, the pressing telescopic device 242 is mounted on the top of the mounting frame 241, the telescopic ends of the pressing telescopic device 242 are connected with pressing plates 244, and the pressing plates 244 are connected with the tops of all the elastic pressing units; the input end of the linkage mechanism 250 is connected to the telescopic end of the pressing telescopic device 242. The pressing telescopic device 242 can be a telescopic air cylinder, a telescopic electric cylinder or a screw rod sliding block, and the telescopic electric cylinder is preferably designed, so that the telescopic amount can be conveniently adjusted. The pressing slot 243 is a frame structure in the present application, and the inner elastic pressing unit is accommodated in the pressing slot 243. The elastic propping unit is of a structure capable of self compression deformation, so that the elastic propping unit is mainly used for adapting to uneven log stacking, the propping quality can be effectively increased, and the phenomenon that the log is stressed and vibrated excessively in the planing process is avoided.

Further, in one embodiment of the present application, in order to better press the log stack, while ensuring that each elastic pressing unit can press the log individually, the elastic pressing unit includes a pressing column 245, a fixing column 246 and a spring 247, the pressing column 245 is slidably installed in the pressing slot 243, one end of the fixing column 246 is fixedly connected with the pressing plate 244, the other end of the fixing column 246 is movably inserted into the other end of the pressing column 245, and the spring 247 is movably sleeved on the fixing column 246 and has both ends fixedly connected with the end face of the pressing column 245 and the pressing plate 244. Wherein, be provided with the movable hole of cooperation with fixed column 246 on the top of roof pressure post 245, such structure is convenient for hold fixed column 246.

The principle of the linkage of the pressing device 240 and the shaving device 230 in the present application is as follows, and after the feeding pushing device 220 pushes all logs to the working area of the shaving device 230 together, the pressing device 240 starts to work. After the pressing telescopic device 242 extends downwards, the pressing column 245 can drive all the elastic pressing units and the sliding blocks 252 to move downwards together until all the elastic pressing units press the logs on the uppermost layer; the sliding block 252 is kept in contact with the swinging arm 231, and the swinging arm 231 abuts against the end of the log stack, so that the abutting telescopic device 242 continues to extend downwards, the sliding block 252 continues to drive the swinging arm 231 to swing downwards, and the elastic abutting unit is compressed under the reaction force of the log stack and the acting force of the abutting telescopic device 242. After the pressing retractors 242 are extended to a certain extent, the knife roller 232 comes into contact with the raw wood, and planing of the raw wood is started. If the operator adjusts the planing space height of the knife roller 232, the pressing telescopic device 242 can be controlled to extend continuously, so that the pressing telescopic device 242 can apply downward force to the swinging arm 231 through the buffer member 256 and the sliding block 252, and then swing downwards, and the elastic pressing unit can not move downwards continuously, so that the spring 247 is compressed continuously. Therefore, the position of the pressing post 245 is not changed during the whole swing angle adjustment of the swing arm 231, and the spring 247 and the buffer 256 are continuously subjected to the pressing force to be correspondingly deformed. After the cutter roll 232 finishes processing the log at the lowest end, the pressing telescopic device 242 is contracted, and the spring 247 and the buffer member 256 are gradually reset due to the action force. Since the buffer 256 is subjected to the smallest force, the swing arm 231 begins to swing upward when the buffer is deformed to be reset. In the process of swinging the swing arm 231 upwards, the acting force of the spring 247 becomes smaller gradually, after the acting force is completely eliminated, the pressing plate 244 drives all the elastic pressing units to move upwards together until the pressing telescopic device 242 is contracted to the minimum extension amount, at this time, the feeding pushing device 220 can extend and push the log stack forwards, after the extension amount is proper, the pressing telescopic device 242 continues to extend, and the above-mentioned process is repeated.

The above embodiments are only preferred embodiments of the present application, and the scope of the present application is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present application are intended to be within the scope of the present application as claimed.
