Description

Technical Field

[0001] This invention belongs to the field of wood processing technology, and specifically relates to a wood shaving device and a wood shaving method. Background Technology

[0002] In the wood processing industry, wood shaving machines are a key piece of equipment, widely used in the processing of materials such as veneer and wood panels. However, existing wood shaving machines have many shortcomings in terms of processing precision, production flexibility, ease of operation, and maintenance costs, which seriously restrict the improvement of production efficiency and product quality.

[0003] First, the installation and adjustment methods of existing wood shaving equipment are often rather crude, resulting in inaccurate blade positioning and dimensional deviations that affect product precision and consistency. Furthermore, the inability to quickly adjust the blade position to accommodate different widths of wood shavings also limits production efficiency.

[0004] Secondly, existing wood shaving equipment has poor production flexibility. Most equipment can only process veneers of specific specifications, making it difficult to adapt to rapid changes in market demand. When processing different specifications or types of veneers is required, it is often necessary to replace the entire machine or disassemble the assembly for complex adjustments, which not only increases production costs but also extends the production cycle. Summary of the Invention

[0005] To address the shortcomings in existing technologies regarding the success rate (yield) and processing efficiency of wood shavings, a wood shaving device and method are proposed. This invention provides the following technical solution:

[0006] A wood shaving device includes a frame, on which a feeding system, a leveling system for leveling wood veneer, and a wood shaving assembly for shaving wood veneer are sequentially mounted from back to front. The leveling system includes an upper conveying roller and a lower conveying roller, with the upper conveying roller positioned above and in front of the lower conveying roller. The wood shaving assembly includes a cutter shaft and multiple cutter discs. The cutter shaft is rotatably connected to the frame, and each cutter disc is sleeved and mounted on the cutter shaft. Each cutter disc has a mounting groove, in which a planer blade is embedded and connected along the direction of the cutter shaft. After the planer blade is placed in the mounting groove, its radial direction is limited.

[0007] Preferably, the planer blade has an L-shaped bent structure.

[0008] Preferably, the shaving assembly further includes a partition for separating the cutter discs, the partition being disposed between two cutter discs, and the cutter discs, partition, and cutter discs being arranged in a axially abutting sequence.

[0009] Preferably, the angle between the line connecting the upper and lower conveying rollers and the horizontal plane is 45-60 degrees, and the minimum distance between the planer blade and the lower conveying roller is less than the minimum distance between the planer blade and the upper conveying roller.

[0010] Preferably, the feeding system includes a pressing assembly and a conveying assembly mounted on the frame. The pressing assembly includes a first roller, a second roller, and a tensioning roller, as well as a pressing belt sleeved on the first roller, the second roller, and the tensioning roller. The conveying assembly includes a first conveying wheel and a second conveying wheel, as well as a conveyor belt sleeved on the first conveying wheel and the second conveying wheel. The lower end face of the conveyor belt is parallel to the upper end face of the conveyor belt.

[0011] Preferably, the compression belt is closely attached to the conveyor belt, and the second roller is located on the upper rear side of the tensioning roller.

[0012] Preferably, the frame is equipped with several mounting layers, each mounting layer is provided with a feeding system, a leveling system and a shaving assembly. A clutch conveyor is provided at the rear of the feeding assembly. The clutch conveyor includes a conveyor and a telescopic drive device. The rear end of the conveyor is hinged to the frame, the lower end of the telescopic drive device is hinged to the frame, and the upper end is hinged to the conveyor. The conveyor can move and connect to the feeding system of each mounting layer after being driven by the telescopic drive device.

[0013] A wood shaving method, using the aforementioned wood shaving device, includes the following steps:

[0014] S1. The wood veneer is conveyed through the feeding system;

[0015] S2. Trim the wood veneer using a leveling system;

[0016] S3, shavings are produced using the shaving assembly.

[0017] Preferably, in step S3, the planer blades on the cutter head are removed or installed to adjust their number and extension length.

[0018] Preferably, in step S3, the pressing belt of the feeding system is in close contact with the conveyor belt, the angle between the line connecting the upper and lower conveyor rollers and the horizontal plane is 45-60 degrees, and the minimum distance between the planer blade and the lower conveyor roller is less than the minimum distance between the planer blade and the upper conveyor roller.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. After the planer blade is placed into the mounting slot, it is restricted in the radial direction. When shaving, the cutter head is locked in the axial direction. When it is necessary to adjust the width of the shavings, the axial lock can be opened to make room for the mounting slot. The planer blade can be installed or removed more quickly, reducing downtime for adjustment and significantly improving overall production efficiency.

[0021] 2. The angle between the line connecting the upper and lower conveyor rollers and the horizontal plane is 45-60 degrees. The minimum distance between the planer blade and the lower conveyor roller is less than the minimum distance between the planer blade and the upper conveyor roller. The veneer is more easily broken by the planer blade, which not only ensures processing efficiency but also makes the success rate of wood shavings higher.

[0022] 3. The multi-layer installation design combined with the clutch conveyor device enables the equipment to flexibly meet the processing needs of different specifications and types of wood veneer. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention.

[0031] Example 1

[0032] like Figure 1-6As shown, a wood shaving device includes a frame 1. From back to front, a feeding system 2, a leveling system 3 for leveling wood veneer, and a wood shaving assembly 4 for shaving the wood veneer are sequentially mounted on the frame 1. The leveling system 3 includes an upper conveying roller 32 and a lower conveying roller 31, with the upper conveying roller 32 positioned above and in front of the lower conveying roller 31. The wood shaving assembly 4 includes a cutter shaft and multiple cutter discs 41. The cutter shaft is rotatably connected to the frame 1, and each cutter disc 41 is fitted onto the cutter shaft. Each cutter disc 41 has a mounting groove 411, which are circumferentially spaced on the cutter disc 41. A connecting element is embedded in the mounting groove 411 along the direction of the cutter shaft. The machine includes a planer blade 42. After the planer blade 42 is inserted into the mounting groove 411, it is radially restricted. By fitting a partition plate 43 between adjacent cutter discs 41, the planer blade 42 is axially restricted. During shaving, the cutter discs 41 are axially locked. When it is necessary to adjust the width of the shavings, the axial locking can be opened to allow the mounting groove 411 to be made available, allowing the planer blade 42 to be installed or removed more quickly. At the same time, by adjusting the circumferential clearance of the planer blades 42 on the same cutter disc 41 in the mounting groove 411, the basic shaving frequency can be adjusted, thereby improving the efficiency and pass rate of shavings; reducing downtime for adjustment, and significantly improving overall production efficiency.

[0033] Specifically, the planer blade 42 has an L-shaped bent structure, which is relatively low in cost and can achieve radial positioning.

[0034] Specifically, the planer 42 includes a blade 421 and an adjusting block 422. The adjusting block 422 is located on the side of the blade 421, forming an L-shaped bend. The mounting groove 411 has multiple adjusting grooves 412 on both sides. The adjusting block 422 can be axially inserted into the mounting groove 411 to achieve radial positioning. At the same time, multiple adjusting grooves 412 are equally spaced, and the number of adjusting grooves 412 exceeds the number of adjusting blocks 422. The radial position and extension length of the blade 421 can be adjusted by adjusting the adjusting block 422, as well as the circumferential distribution density (i.e., the number of teeth), thereby quickly adjusting the planing parameters.

[0035] Specifically, the wood shaving assembly 4 also includes a partition for separating the cutter discs 41. The partition is disposed between the two cutter discs 41. The cutter discs 41, the partition, and the cutter discs 41 are arranged in sequence in an axial abutment to achieve axial locking or unlocking of the cutter discs 41.

[0036] Specifically, the angle between the line connecting the upper conveyor roller 32 and the lower conveyor roller 31 and the horizontal plane is 45-60 degrees. The minimum distance between the planer blade 42 and the lower conveyor roller 31 is less than the minimum distance between the planer blade 42 and the upper conveyor roller 32. The veneer has a certain degree of flexibility and will hang down after leaving the lower conveyor roller 31 at the end. After multiple verifications, when the angle between the line connecting the upper conveyor roller 32 and the lower conveyor roller 31 and the horizontal plane is 45-60 degrees, the veneer is more easily broken by the planer blade 42. Under the condition of ensuring processing efficiency, the success rate of wood shavings is higher at this time.

[0037] Specifically, the feeding system 2 includes a pressing assembly 22 and a conveying assembly 21 mounted on the frame 1. The pressing assembly 22 includes a first roller 221, a second roller 222, and a tensioning roller 223, as well as a pressing belt sleeved on the first roller, the second roller, and the tensioning roller 223. The conveying assembly 21 includes a first conveying wheel 211 and a first conveying wheel 212, as well as a conveyor belt sleeved on the first conveying wheel 211 and the first conveying wheel 212. The lower end face of the conveyor belt is parallel to the upper end face of the conveyor belt. The pressing belt is tightly attached to the conveyor belt. The second roller 222 is located on the rear upper side of the tensioning roller 223, forming a triangular feeding space. The veneer can smoothly enter under the pressing belt and maintain a high degree of flatness under the action of the pressing belt, thereby ensuring that the angle of the veneer remains consistent during cutting and effectively improving the success rate of veneer shavings.

[0038] Specifically, the leveling system 3 further includes an elastic pressing component 33, which is fixedly connected to the frame 1 via a mounting plate. The front end of the elastic pressing component 33 extends between the first conveying roller 212 and the first conveying roller 221, and between the lower conveying roller and the upper conveying roller, and can press against the veneer to guide and level the veneer surface, thereby improving the rigidity of the veneer. When planed, it can maintain a fixed angle and a high degree of consistency on both sides, thus effectively improving the consistency and yield of veneer shavings. Preferably, the elastic pressing component 33 is an arc-shaped plate.

[0039] Specifically, the frame 1 has two mounting layers, each equipped with a feeding system 2, a leveling system 3, and a shaving assembly 4. A clutch conveyor 5 is located behind the feeding assembly. The clutch conveyor 5 includes a conveyor 51 and a telescopic drive device 52. The rear end of the conveyor 51 is hinged to the frame 1, and the lower end of the telescopic drive device 52 is hinged to the frame 1, while the upper end is hinged to the conveyor 51. The conveyor 51 can move and connect to the feeding system 2 of each mounting layer after being driven by the telescopic drive device 52. Therefore, different mounting layers can be selected according to different veneer specifications or different shaving processing specifications during feeding. The planer blades 42 of each mounting layer correspond to different specifications of shavings, thereby realizing the processing of multiple specifications of shavings at one time and further improving the efficiency of shavings processing.

[0040] Example 2

[0041] Based on Example 1, a cleaning brush or scraper is installed between the pressing belt and the conveyor belt to clean the belt surface regularly and prevent the accumulation of impurities such as wood chips from affecting the pressing effect.

[0042] Furthermore, the tensioning wheel 223 adopts a spring-loaded design to ensure that the clamping band maintains a stable clamping force under different thicknesses of wood veneer.

[0043] Furthermore, the surfaces of the upper conveyor roller 32 and the lower conveyor roller 31 are covered with wear-resistant and anti-slip materials to increase the friction with the wood veneer and prevent slippage. A tension adjustment mechanism is added to allow adjustment of the pressure between the upper conveyor roller 32 and the lower conveyor roller 31 according to the thickness of the wood veneer, ensuring the flatness of the wood veneer.

[0044] Furthermore, on the rear side of the installation layer, i.e. the material receiving side, sensors for identifying different veneer specifications are set up, and a PLC control system is integrated. Through the telescopic drive device 52, the processing position is automatically matched to realize the automatic adjustment and monitoring of feeding speed, planing depth, and shaving width.

[0045] Furthermore, the clutch conveyor 5 is installed on the frame 1 of the rotary cutting machine 6, which can realize the integration of rotary cutting and shavings, and improve processing efficiency.

[0046] Example 3

[0047] Based on Example 2, the steps of the wood shaving method include:

[0048] S1. The wood veneer is conveyed through the feeding system 2;

[0049] Different mounting layers are preset and matched with different specifications (including thickness, width and length). If the corresponding specifications of the incoming material can be found in the preset mounting layers, it will be matched to the corresponding mounting layer by the telescopic drive device 52.

[0050] S2. Trim the veneer using the leveling system 3;

[0051] At this time, the pressing belt of the feeding system 2 is in close contact with the conveyor belt.

[0052] S3, shavings are produced by shaving assembly 4;

[0053] When shaving, the angle between the line connecting the upper conveyor roller 32 and the lower conveyor roller 31 and the horizontal plane is 45-60 degrees, and the minimum distance between the planer blade 42 and the lower conveyor roller 31 is less than the minimum distance between the planer blade 42 and the upper conveyor roller 32.

[0054] If the corresponding specifications of the incoming material cannot be found in the preset mounting layer, the planer blades 42 on the cutter head 41 of one or more mounting layers can be removed or installed to adjust the quantity and extension length, adjust the shaving width and speed, and improve the shaving yield. Different mounting layers are independent of each other, and when one mounting layer is removed or installed, the other mounting layers can also work, thereby improving work efficiency.

[0055] Furthermore, this device integrates a PLC control system to achieve automatic adjustment and monitoring of feeding speed, shaving depth, and shaving width, thereby improving automation and processing efficiency.
