Description

Technical Field

[0001] This invention relates to the field of board processing technology, specifically to a wood shavings production line. Background Technology

[0002] Wood shaving machines are mainly used to mass-produce thin wood shavings of uniform thickness. These thin wood shavings are generally used as raw materials for particleboard. Because they retain some of the original wood fiber structure, particleboard has higher strength and better wear resistance compared to traditional particleboard.

[0003] Currently, wood shavings are generally obtained by planing logs or wood chips using shaving equipment. Logs are typically cut to a fixed size during the logging process, and their dimensions are generally 1.4, 2.8, and 3.2 meters to facilitate transportation and adapt to different processing designs or requirements. Log planing methods include reciprocating planing along the log's axis and using a drum-type cross-cutting planer. While the horizontal reciprocating cutting method can accommodate logs of all sizes and produces relatively long shavings, it can only process one log at a time, resulting in low processing efficiency. For example, patent CN113524374A discloses a multi-layer wood shaving device. In contrast, the drum-type planing method can plan multiple logs simultaneously, significantly improving processing efficiency. For example, patent CN106476105A discloses a novel wood shaving machine that employs a rotating cutter cylinder for full-circumferential wood cutting. This allows for simultaneous circumferential cutting of a large quantity of wood at once, effectively increasing the contact cutting area and thus significantly improving wood processing efficiency. However, the cage-like internal cutting structure of the aforementioned design limits the length and size of the logs or pieces of wood placed inside the rotating cutter cylinder. This is primarily due to structural limitations and the risk of collisions between excessively long or large pieces and the cylinder during rotation, leading to deformation of the internal cutters. Furthermore, the lowered center of gravity of the entire rotating cutter cage causes excessive vibration. Additionally, due to the rotating cutter cylinder processing method and structural size limitations, this type of equipment cannot process multiple logs simultaneously, making it unsuitable for large-scale particleboard processing. Summary of the Invention

[0004] In order to overcome one of the shortcomings of the prior art, the purpose of this invention is to provide a wood shaving production line that can process multiple long logs at the same time with high processing efficiency.

The spring is movably fitted onto the fixed column, and both ends are fixedly connected to the end face of the pressure column and the pressure plate, respectively.

[0011] Furthermore, the feeding pusher includes a sliding base, a pusher arm hinged to one end of the sliding base, and a pusher head mounted on the other end of the pusher arm. The sliding base is capable of reciprocating in the area of ​​the receiving channel between the shaving device and the timber stacking feeding device.

One end of the feeding mechanism is connected to one side of the stacking bin, and the other end is connected to the receiving channel. The axial direction of the logs conveyed by the feeding mechanism is the same as the length direction of the receiving channel. The loosening and pushing mechanism is located at the bottom of the stacking bin and is provided with at least two wedge blocks. The slope of the wedge blocks faces the feeding side of the feeding mechanism, and both wedge blocks can move along the feeding direction of the feeding mechanism.

[0013] Furthermore, the loosening and pushing mechanism includes a pusher and a pusher frame.

Simultaneously, the neatly stacked logs within the receiving channel allow the pushing device to push multiple logs into the shavings device at once, enabling the shavings device to plane one end of multiple logs simultaneously, thus improving processing efficiency. The pressing device also secures multiple logs, preventing them from jumping during processing and improving overall stability. Furthermore, the swinging design of the shavings device and its linkage with the pressing device allow the pressing device to simultaneously drive the shavings device downwards, thereby driving the working end of the shavings device downwards for planing. This allows processing log stacks taller than the working end of the shavings device, further improving processing efficiency. This wood shaving equipment can process multiple logs simultaneously without requiring rough processing, reducing processing difficulty and cost, and can adapt to processing needs of different specifications and sizes.

[0029] Wood shavings collection device 300. Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] See Figures 1 to 7This application provides a wood shavings production line, including a wood stacking and feeding device 100, a wood shavings device 200, and a wood shavings collecting device 300. The wood stacking and feeding device 100 is used to receive stacks of logs and organize them for outputting logs one by one. The wood shavings device 200 includes a frame 210, a feeding and pushing device 220, a wood shavings device 230, and a pressing device 240. The frame 210 is provided with a receiving channel 211 for accommodating logs. One side of the receiving channel 211 is connected to the output end of the wood stacking and feeding device 100. The feeding and pushing device 230... The 20 and the shaving device 230 are respectively installed at both ends of the receiving channel 211. The pressing device 240 is installed in the area of ​​the receiving channel 211 between the pushing device and the shaving device 230. The feeding pushing device 220 can push the logs output by the timber stacking and feeding device 100 into the shaving device 230. The pressing device 240 can press the log stack in the receiving channel 211 and simultaneously drive the shaving device 230 to swing. The shaving collection device 300 is used to receive the shavings discharged by the shaving device 230.

[0032] In this application, the wood shavings collection device 300 can be a conventional conveyor belt structure. Since the wood shavings collection device 230 may collect stones or other debris from the surface of the logs during the shavings collection process, which can cause problems for subsequent shavings processing, the wood shavings collection device 300 can also incorporate a vibration structure to separate the debris from the shavings. Furthermore, the receiving channel 211 in this application has a U-shaped cross-section, which facilitates the holding of multiple logs. One side of the receiving channel 211 has a notch that connects to the output end of the timber stacking and feeding device 100. The output end of the timber stacking and feeding device 100 is higher than the bottom of the receiving channel 211, allowing the timber stacking and feeding device 100 to output and stack multiple layers of logs into the receiving channel 211.

[0033] It should be further explained that, in this application, in order to facilitate the buffering of logs when they are output from the timber stacking and feeding device 100, and to ensure that the falling position is located in the central area of ​​the receiving channel 211 so that the pressing device 240 can press them down later, in an improved embodiment of this application, receiving buffer frames are provided on both sides of the corresponding position of the receiving channel 211 at the output end of the timber stacking and feeding device 100. Guide plates are inclined downward on the receiving buffer frames, and the two guide plates are designed in a figure-eight shape. This allows the logs from the timber stacking and feeding device 100 to roll onto the guide plates, so that the logs will fall into the central area of ​​the receiving channel 211 due to the restriction of the two guide plates.

[0034] In the above embodiments, the wood shaving production line uses the wood stacking and feeding device 100 to organize the logs from the outside and output them one by one. This can effectively reduce the pre-processing and facilitate the log stacks to be transported one by one into the receiving channel 211 for neat stacking, making it easier for the pressing device 240 to press all the logs together later. At the same time, the neatly stacked logs in the receiving channel 211 also facilitate the pushing device to push multiple logs into the shaving device 230 at one time. This makes it easier for the shaving device 230 to plan one end of multiple logs at the same time, improving the processing efficiency. The pushing device presses and fixes multiple logs, ensuring that the logs will not jump during processing by the shaving device 230, thus improving the stability of the entire processing. Furthermore, the swinging design of the wood shaving device 230 and its linkage with the pressing device 240 allow the pressing device 240 to simultaneously drive the wood shaving device 230 downwards while pressing, thereby causing the working end of the wood shaving device 230 to plane downwards. This enables the processing of log stacks with a height greater than the working end of the wood shaving device 230, improving processing efficiency. This wood shaving equipment 200 can process multiple logs simultaneously without the need for rough processing, reducing processing difficulty and cost, and can adapt to processing needs of different specifications and sizes.

[0035] See further Figures 1 to 4 The timber stacking and feeding device 100 includes a frame 110, a feeding mechanism 120, and a loosening and pushing mechanism 130. A stacking bin 140 is mounted on the frame 110. One end of the feeding mechanism 120 is connected to one side of the stacking bin 140, and the other end is connected to the receiving channel 211. The axial direction of the logs conveyed by the feeding mechanism 120 is the same as the length direction of the receiving channel 211. The loosening and pushing mechanism 130 is located at the bottom of the stacking bin 140 and has at least two wedge-shaped blocks 131. The slope of each wedge-shaped block 131 faces the feeding side of the feeding mechanism 120, and both wedge-shaped blocks 131 can move along the feeding direction of the feeding mechanism 120. The overall height of the loosening and pushing mechanism 130 is greater than the height of the bottom of the stacking bin 140, which facilitates the logs rolling into the feeding mechanism 120. It should be noted that in this application, the feeding mechanism 120 can be a conventional conveyor belt mechanism, and the unloading and pushing mechanism 130 can be a conventional telescopic cylinder mechanism, etc.

[0036] See further Figure 3 and Figure 4The loosening and pushing mechanism 130 includes a pusher 132 and a pusher frame 133. The pusher 132 is installed on the bottom of the stacking bin 140, and the pusher frame 133 is slidably installed on the bottom of the stacking bin 140. The output end of the pusher 132 is connected to the pusher frame 133. Two wedge blocks 131 are respectively installed on both ends of the pusher frame 133. The pusher 132 can drive the pusher frame 133 to move along the feeding direction of the feeding mechanism 120. Specifically, the pusher frame 133 is slidably installed on a groove on the bottom outer side of the stacking bin 140. The main function of this is to restrict the pusher frame 133 and also to prevent bark or debris from falling from the logs in the stacking bin 140 from entering the groove and affecting the normal sliding of the pusher frame 133. Therefore, in one embodiment, a clearance hole is provided on the bottom of the storage bin 140, a portion of the pusher 133 passes through the clearance hole, and a wedge block 131 is installed on the protruding portion. The pusher 132 in this application can be a conventional telescopic cylinder or a motor screw structure.

[0037] Furthermore, since the wedge block 131 is prone to damage due to the need to continuously push the stacked logs, in one embodiment, mounting seats 134 are provided at both ends of the pushing frame 133. The bottom surface of the wedge block 131 has a receiving groove 135 for engaging with the mounting seat 134. A positioning hole is provided on the area corresponding to the receiving groove 135 on the wedge block 131. A through hole is provided on the mounting seat 134 to engage with the positioning hole. The wedge block 131 is secured to the pushing frame 133 by bolts passing through the positioning hole and the through hole in sequence. This arrangement facilitates the replacement of the wedge block 131 to a certain extent; simultaneously, the engagement of the receiving groove 135 and the mounting seat 34 ensures that the pushing frame 133 can transmit sufficient pushing force to the wedge block 131.

[0038] See Figure 3 and Figure 4In one embodiment of this application, the feeding mechanism 120 includes a receiving platform 121, a conveyor chain 122, and a feeding motor 123. The receiving platform 121 is mounted on the frame 110 and located on the side of the material discharge from the stacking silo 140. A limiting guide plate 124 is provided above the receiving platform 121, with the end of the limiting guide plate 124 near the material discharge from the stacking silo 140 being higher than the end near the material discharge from the receiving platform 121. Rotating shafts 125 are rotatably mounted on both ends of the receiving platform 121, and elongated holes 126 are provided along the length of both sides of the receiving platform 121. Feeding gears are provided on both rotating shafts 125 at positions corresponding to the elongated holes 126. 127, two feeding gears 127 on the same elongated hole 126 are connected by the conveying chain 122, and the feeding motor 123 is connected to one end of any of the rotating shafts 125 through a reducer; the frame 110 is provided with a receiving feeding chain 111 at the bottom of the receiving platform 121, and a receiving guide 112 is provided on the end of the frame 110 near the material discharge end of the receiving platform 121. The receiving guide 112 is connected to one end of the receiving feeding chain 111, and the other end of the receiving feeding chain 111 is connected to one side of the accommodating channel 211. Several partitions are provided on the receiving feeding chain 111, and a bearing space for accommodating logs is formed between two adjacent partitions.

[0039] The logs are conveyed using conveyor chains 122, which effectively supports them. It should be noted that the two conveyor chains 122 extend above the upper surface of the receiving platform 121. This prevents bent logs from rubbing against the upper surface of the receiving platform 121 during transport, or reduces the rubbing area, thus improving the quality of transport. Furthermore, in this application, the side guards at the feeding end of the receiving platform 121 are designed in a trumpet shape. This facilitates the wedge blocks 131 pushing and feeding the logs onto the receiving platform 121, improving the efficiency of log self-positioning. In the above embodiment, the main purpose of the receiving and feeding chain 111 is to reduce the overall length of the equipment, lower the space occupancy rate, and provide sufficient transport distance to cooperate with other equipment for log feeding one by one.

[0040] In one embodiment, since the logs need to be confined and ultimately conveyed log by log, a discharge guide plate 128 is provided above the receiving platform 121 to prevent the logs from jumping and shifting due to friction between the logs and the sides of the receiving platform 121 during the conveying process. The end of the discharge guide plate 128 near the discharge of the stacking hopper 140 is higher than the end near the discharge of the receiving platform 121. The discharge guide plate 128 effectively confines the logs to the conveying channel formed between them and the receiving platform 121.

[0041] See Figure 1 , Figure 5 and Figure 6 In one embodiment of this application, the feeding pusher 220 includes a sliding base 221, a pusher arm 222 hinged at one end to the sliding base 221, and a pusher head 223 mounted on the other end of the pusher arm 222. The sliding base 221 is capable of reciprocating in the area of ​​the receiving channel 211 between the shaving device 230 and the timber stacking and feeding device 100. A swing arm telescopic member 224 is hinged to the sliding base 221, and the other end of the swing arm telescopic member 224 is hinged to the pusher arm 222. A drive motor 225 is mounted on the sliding base 221, and a drive gear 226 is mounted on the output end of the drive motor 225. A rack 213 that meshes with the drive gear 226 is provided on the receiving channel 211.

[0042] In an improved embodiment, the lower side of the pusher head 223 is provided with several mounting slots, and fork teeth are detachably mounted on the mounting slots. After most of the log structure has been planed, if the log is too short and the pressing device 240 cannot fully press the end of the log, the pusher head 223 can extend under the pressing device 240 and press the end of the log with the fork teeth to press the end of the log firmly onto the receiving channel 211. Then, in conjunction with the shaving device 230, planing can be performed to the maximum extent, thus avoiding waste.

[0043] In the above embodiments, to facilitate the movement of the sliding base 221 relative to the receiving channel 211, in one embodiment, the sliding base 221 can be slidably connected to the receiving channel 211. However, in actual use, the receiving channel 211 will inevitably contain impurities such as dust and sawdust, which can damage the sliding pair. Therefore, in an improved embodiment, at least two rollers 227 are provided on both sides of the sliding base 221, and tracks 214 that cooperate with the rollers 227 are provided on both sides of the bottom of the receiving channel 211. The use of rollers 227 can adapt to the working environment with high dust and many impurities.

[0044] In an improved embodiment, an improved embodiment of the feeding pusher device 220 is also provided. The feeding pusher device 220 includes a pusher motor, a pusher screw, and a pusher seat fitted onto the pusher screw via a screw sleeve. A sliding groove is provided on the bottom of the receiving channel 211. The pusher screw is rotatably mounted on the back of the receiving channel 211. The pusher motor is connected to one end of the pusher screw, and one end of the pusher seat movably passes through the sliding groove and is placed within the receiving channel 211. In this embodiment, the pusher motor and pusher screw can be replaced with a design of a motor and a chain.

[0045] See further Figure 1 and Figure 5 The wood shaving device 230 includes a swing arm 231, a cutter roller 232 rotatably mounted on the outward end of the swing arm 231, and a plurality of planer blades 233 disposed on the outer periphery of the cutter roller 232. One end of the swing arm 231 is mounted on the frame 210 via a reset damping shaft 234, which can drive the swing arm 231 to reset. A wood shaving motor 235 is disposed on the swing arm 231 or the frame 210. The wood shaving motor 235 drives the cutter roller 232 to rotate via a belt. A linkage mechanism 250 is disposed on the swing end of the swing arm 231, and the linkage mechanism 250 is connected to the output end of the pressing device 240. The frame 210 is provided with discharge ports 212 on both sides of the cutter roller 232, and the discharge ports 212 are connected to the wood shaving collection device 300.

[0046] The cutter roller 232 is actually a cylindrical or cage-like structure. When the planer blades 233 are planing, the wood shavings enter the cutter roller 232 through the gaps between adjacent planer blades 233 and are then discharged from both ends. In some embodiments, the planer blades 233 are extended structures, which can utilize the design in patent CN210061474U - A Wood Shaving Machine for Rabbit Shed Preparation, which is not detailed here. Furthermore, the wood shaving motor 235 is mounted on the swing arm 231, allowing the motor and arm to swing together, thus ensuring a fixed distance between the motor and roller 232 and stable transmission. The reset damping shaft 234 is designed to allow the swing arm 231 to swing upwards naturally, and the spring damping shaft is essentially a shaft with a reset coil spring. Of course, in some embodiments, the wood chip motor 235 can also be mounted on the frame 210, and the hinge between the swing arm 231 and the frame 210 can be connected by a rotating shaft. At the same time, the swing is driven by a telescopic cylinder. In this case, the linkage mechanism 250 is not required. A double-groove transmission wheel is rotatably mounted on the rotating shaft. One groove of the double-groove transmission wheel is connected to the wood chip motor 235 by a belt, and the other groove is connected to the cutter roller 232 by a belt.

[0047] It is important to note that during the planing process, because the thickness of each multi-layered log stack varies, and the size of the cutter roller 232 is fixed or not conducive to frequent disassembly and assembly, it is impossible for the cutter roller 232 to completely cover all the log ends in actual use. Therefore, the pressing device 240 can be used to allow the entire cutter roller 232 to swing downwards around all the log stack ends for planing. This design allows the cutter roller 232 to process log stacks thicker than its diameter. Furthermore, the main purpose of the linkage mechanism 250 is to ensure that the pressing device 240 first presses down on the log stack to prevent it from becoming loose during planing. During continued downward pressure, the linkage mechanism 250 drives the swing arm 231 to swing, causing the cutter roller 232 to plan the log from top to bottom; while the pressing device 240 continues to press down on the log stack.

[0048] See further Figure 7 The linkage mechanism 250 includes a fixed frame 251 mounted on the frame 210, a sliding block 252 slidably mounted on the fixed frame 251, and a pressing arm 253 mounted on the sliding block 252. A groove 254 is provided on one end of the pressing arm 253, and a sliding column 255 is slidably mounted within the groove 254. The sliding column 255 is mounted on one swinging end of the swing arm 231. The upper end of the sliding block 252 is connected to the output end of the pressing device 240 via a buffer 256. When the pressing device 240 presses down, the buffer 256 is compressed, and simultaneously the sliding block 252 slides downward, thus pressing the swing arm 231 downward. The design of the sliding column 255 and the groove 254 allows the swing arm 231 sufficient space to swing. In effect, through this linkage structure, the pressing device 240 can synchronously adjust the swing angle of the swing arm 231 when pressing against the log stack, thereby controlling the planing range of the cutter roller 232. In this application, the buffer 256 is a spring. Its main function, in addition to delaying the movement of the sliding block 252, is to absorb the vibration of the cutter roller 232 during the planing process and prevent these vibrations from being transmitted to the pressing device 240.

[0049] See further Figure 5 and Figure 7To achieve the aforementioned design of pressing down on the log stack and simultaneously driving the swing arm 231, the pressing device 240 includes a mounting frame 241, several elastic pressing units, and a pressing telescopic device 242. The mounting frame 241 is installed on the area above the receiving channel 211 of the frame 210. The mounting frame 241 has several pressing slots 243, and the elastic pressing units are slidably installed in the pressing slots 243. The pressing telescopic device 242 is installed on the top of the mounting frame 241, and a top pressure plate 244 is connected to the telescopic end of the pressing telescopic device 242. The top pressure plate 244 is connected to the top 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 cylinder, a telescopic electric cylinder, or a lead screw slider design. This application prefers a telescopic electric cylinder design, which facilitates adjustment of the telescopic amount. In this application, the pressure groove 243 is designed as a frame structure, and the elastic pressure unit is housed within the pressure groove 243. The elastic pressure unit is a structure capable of self-compression and deformation, which is mainly to adapt to uneven log stacks. This can effectively increase the pressure mass and prevent excessive vibration of the logs during planing.

[0050] Furthermore, in one embodiment of this application, in order to better compress the stack of logs while ensuring that each elastic compressing unit can individually compress the logs, the elastic compressing unit includes a top-pressure column 245, a fixed column 246, and a spring 247. The top-pressure column 245 is slidably installed in the compressing groove 243. One end of the fixed column 246 is fixedly connected to the top-pressure plate 244, and the other end of the fixed column 246 is movably inserted into the other end of the top-pressure column 245. The spring 247 is movably fitted onto the fixed column 246, and both ends are fixedly connected to the end face of the top-pressure column 245 and the top-pressure plate 244, respectively. The top of the top-pressure column 245 is provided with a movable hole that mates with the fixed column 246, which facilitates the accommodation of the fixed column 246.

[0051] The principle of linkage between the pressing device 240 and the shaving device 230 in this application is as follows: After the feeding and pushing device 220 pushes all the logs into the working area of ​​the shaving device 230, the pressing device 240 begins to work. When the pressure expansion joint 242 extends downwards, the pressing column 245 drives all the elastic pressure units and the sliding block 252 to move downwards together until all the elastic pressure units are pressed against the top layer of logs. The sliding block 252 remains in contact with the swing arm 231, which then abuts against the end of the log stack. For this purpose, the pressure expansion joint 242 continues to extend downwards, and the sliding block 252 continues to drive the swing arm 231 to swing downwards. Under the reaction force of the log stack and the force of the pressure expansion joint 242, the spring 247 of the elastic pressure unit is compressed. After the pressure expansion joint 242 extends to a certain extent, the cutter roller 232 begins to contact the logs, and the logs begin to be planed. If the operator wants to adjust the planing space height of the cutter roller 232, the pressure expansion joint 242 can be extended further. This allows the pressure expansion joint 242 to apply a downward force to the swing arm 231 through the buffer 256 and sliding block 252, causing it to swing downwards. Since the elastic pressure unit cannot continue to move downwards, the spring 247 remains compressed. Therefore, during the adjustment of the swing angle of the entire swing arm 231, the position of the top pressure column 245 remains unchanged, while the spring 247 and buffer 256 continuously undergo corresponding deformation under pressure. After the cutter roller 232 has finished processing the bottom of the log, the pressure expansion joint 242 retracts. At this time, the spring 247 and buffer 256 gradually return to their original positions due to the reduced force. Since the buffer 256 experiences the least force, it is the first to return to its original position, causing the swing arm 231 to begin swinging upwards. As the swing arm 231 swings upward, the force of the spring 247 gradually decreases. Once the force disappears completely, the top pressure plate 244 will drive all the elastic pressing units to move upward together until the pressing telescopic device 242 retracts to its minimum extension. At this point, the feeding pusher 220 can extend and push the log stack forward. Once the extension is appropriate, the pressing telescopic device 242 continues to extend and repeats the above process.

[0052] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
