Technical Field

[0001] The invention belongs to the technical field of wood processing, and in particular relates to a wood shaving device and a wood shaving method thereof. Background Art

[0002] In the wood processing industry, the shaving device is one of the key equipment and is widely used in the processing of materials such as veneer and wood boards. However, the existing shaving devices have many shortcomings in processing accuracy, production flexibility, operation convenience and maintenance cost, which seriously restricts the improvement of production efficiency and product quality.

[0003] First, the installation and adjustment methods of the existing planer devices are often rough, the positioning of the planer is not accurate enough, and dimensional deviations are prone to occur, affecting the accuracy and consistency of the product. At the same time, since the planer position cannot be quickly adjusted to meet the needs of planings of different widths, production efficiency is also limited.

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

[0005] In view of the problem that the shaving success rate (yield rate) and processing efficiency in the prior art need to be improved, a shaving device and a shaving method are proposed. The present invention provides the following technical solutions: A shaving device comprises a frame, on which a feeding system, a leveling system for leveling veneer, and a shaving assembly for slicing veneer are installed in sequence from back to front; the leveling system comprises an upper conveying roller and a lower conveying roller, and the upper conveying roller is arranged on the front upper side of the lower conveying roller; the shaving assembly comprises a knife shaft and a plurality of knife discs; the knife shaft is rotatably connected to the frame, and each knife disc is sleeved and installed on the knife shaft; the knife disc is provided with a mounting groove, and a planer is embedded and connected in the mounting groove along the direction of the knife shaft, and the radial direction of the planer is limited after the planer is placed in the mounting groove.

[0006] Preferably, the planer is an L-shaped bending structure.

[0007] Preferably, the shavings assembly further comprises a partition plate for separating the cutter discs, wherein the partition plate is arranged between the two cutter discs, and the cutter discs, the partition plate and the cutter discs are sequentially arranged in axial abutment with each other.

[0008] Preferably, the angle between the connecting line of the upper conveying roller and the lower conveying roller and the horizontal plane is 45-60 degrees, and the minimum distance between the planer and the lower conveying roller is smaller than the minimum distance between the planer and the upper conveying roller.

[0010] Preferably, the compression belt is arranged in close contact with the conveyor belt, and the second roller is arranged on the upper rear side of the tensioning wheel.

[0011] Preferably, several mounting layers are installed on the frame, and each mounting layer is provided with a feeding system, a leveling system and a shavings assembly. A clutch conveying device is provided on the rear side of the feeding assembly, and the clutch conveying device includes a conveyor and a telescopic driving device. The rear end of the conveyor is hinged to the frame, the lower end of the telescopic driving device is hinged to the frame, and the upper end is hinged to the conveyor. The conveyor can be moved and docked to the feeding system of each mounting layer after being driven by the telescopic driving device.

[0012] A wood shaving method is carried out using the wood shaving device, and the steps include: S1, conveying veneer through a feeding device; S2, trimming the veneer by means of a trimming device; S3, shavings are made through the shaving assembly.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. After the planer is placed in the installation slot, the radial direction is limited. When planing, the cutter disc is locked in the axial direction. When the width of the planing needs to be adjusted, the axial lock can be opened to make way for the installation slot.

DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. The directional words mentioned in the following embodiments, such as "up", "down", "left" and "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0018] Example 1 like Figure 1-6As shown, a shaving device comprises a frame 1, on which a feeding system 2, a leveling system 3 for leveling veneer, and a shaving assembly 4 for slicing veneer are sequentially installed from back to front; the leveling system 3 comprises an upper conveying roller 32 and a lower conveying roller 31, and the upper conveying roller 32 is arranged on the front upper side of the lower conveying roller 31; the shaving assembly 4 comprises a knife shaft and a plurality of knife discs 41; the knife shaft is rotatably connected to the frame 1, and each knife disc 41 is sleeved and installed on the knife shaft, and the knife disc 41 is provided with mounting grooves 411, and the mounting grooves 411 are arranged on the knife disc 41 at equal intervals in the circumferential direction, and the mounting grooves 411 are embedded with connecting members along the knife shaft direction. There is a planer 42, which is limited in radial direction after being placed in the installation groove 411. The planer 42 is limited in axial direction by arranging a partition plate 43 between adjacent cutter discs 41. The cutter disc 41 is locked in axial direction during planing. When the width of the planing needs to be adjusted, the axial lock can be opened to make way for the installation groove 411, so that the planer 42 can be installed or removed more quickly. At the same time, the basic planing frequency can be adjusted by adjusting the circumferential gap of the planer 42 on the same cutter disc 41 with the installation groove 411, thereby improving the efficiency and qualified rate of planing; reducing the downtime adjustment time and significantly improving the overall production efficiency.

[0019] Specifically, the planer 42 is an L-shaped bending structure, which has a relatively low cost and can achieve radial limitation.

[0020] Specifically, the planer 42 includes a tool rod 421 and an adjusting block 422. The adjusting block 422 is arranged on the side of the tool rod 421 to form an L-shaped bent portion. The mounting groove 411 is provided with multiple adjusting grooves 412 on both sides. The adjusting block 422 can be axially inserted into the mounting groove 411, thereby realizing radial limitation. At the same time, multiple adjusting grooves 412 are arranged at equal intervals, and the number of adjusting grooves 412 is greater than the number of adjusting blocks 422. The radial position and extension length of the tool rod 421 can be adjusted through the adjusting block 422, and the circumferential distribution density (i.e., the number of teeth) can also be adjusted, thereby quickly adjusting the planing parameters.

[0021] Specifically, the shaving assembly 4 further includes a partition plate for separating the cutter discs 41 , and the partition plate is disposed between two cutter discs 41 . The cutter discs 41 , the partition plate, and the cutter discs 41 are sequentially axially abutted and arranged to achieve axial locking or unlocking of the cutter discs 41 .

[0022] Specifically, the angle between the line connecting the upper conveying roller 32 and the lower conveying roller 31 and the horizontal plane is 45-60 degrees, the minimum distance between the planer 42 and the lower conveying roller 31 is smaller than the minimum distance between the planer 42 and the upper conveying roller 32, and the veneer has a certain flexibility. After the end leaves the lower conveying roller 31, it will droop downward. After many verifications, when the angle between the line connecting the upper conveying roller 32 and the lower conveying roller 31 and the horizontal plane is 45-60 degrees, the veneer is more easily interrupted by the planer 42. Under the condition of ensuring processing efficiency, the success rate of shavings is higher at this time.

[0023] Specifically, the feeding system 2 includes a clamping assembly 22 and a conveying assembly 21 arranged on the frame 1, the clamping assembly 22 includes a first roller 221, a second roller 222 and a tensioning wheel 223, and a clamping belt sleeved on the first roller, the second roller and the tensioning wheel 223, the conveying assembly 21 includes a first conveying wheel 211 and a first conveying wheel 212, and a conveying belt sleeved on the first conveying wheel 211 and the first conveying wheel 212, the lower end surface of the conveying belt is arranged parallel to the upper end surface of the conveying belt, the clamping belt is arranged closely to the conveying belt, the second roller 222 is arranged on the upper rear side of the tensioning wheel 223, forming a triangular feeding space, the veneer can smoothly enter under the clamping belt, and maintain a high degree of flatness under the action of the clamping belt, thereby ensuring that the angle of the veneer is consistent during cutting, effectively improving the shaving success rate of the veneer.

[0024] Specifically, the leveling system 3 further includes an elastic material pressing piece 33, which is fixedly connected to the frame 1 through a mounting plate, and the front end of the elastic material pressing piece 33 extends between the first conveying wheel 212 and the first conveying wheel 221, and between the lower conveying roller and the upper conveying roller, and can be pressed against the veneer to guide the veneer and regularize the wood surface, thereby improving the rigidity of the veneer, and being able to maintain a fixed angle when being sliced ​​and maintain a high consistency on both sides, thereby effectively improving the consistency and yield rate of the veneer shavings. Preferably, the elastic material pressing piece 33 is an arc-shaped plate.

[0025] Specifically, two installation layers are installed on the frame 1, and each installation layer is provided with a feeding system 2, a leveling system 3 and a shavings assembly 4. A clutch conveying device 5 is provided on the rear side of the feeding assembly, and the clutch conveying device 5 includes a conveyor 51 and a telescopic driving device 52. The rear end of the conveyor 51 is hinged to the frame 1, the lower end of the telescopic driving device 52 is hinged to the frame 1, and the upper end is hinged to the conveyor 51. The conveyor 51 can be moved and docked to the feeding system 2 of each installation layer after being driven by the telescopic driving device 52. Therefore, when feeding, different installation layers can be selected according to different veneer specifications or different shavings processing specifications. The planer 42 of each installation layer is set corresponding to shavings of different specifications, thereby realizing one-time processing of shavings of multiple specifications, further improving the efficiency of shavings.

[0026] Example 2 On the basis of Example 1, a cleaning brush or scraper is provided between the compression belt and the conveyor belt to regularly clean the belt surface to prevent the accumulation of impurities such as sawdust and so on from affecting the compression effect.

[0027] Furthermore, the tension wheel 223 is designed to be spring loaded to ensure that the compression belt can maintain a stable compression force under different veneer thicknesses.

[0028] Furthermore, the upper conveying roller 32 and the lower conveying roller 31 are covered with wear-resistant and anti-skid materials to increase the friction on the veneer and prevent slipping. A tension adjustment mechanism is added to allow the pressure between the upper conveying roller 32 and the lower conveying roller 31 to be adjusted according to the thickness of the veneer to ensure the flatness of the veneer.

[0029] Furthermore, a sensor for identifying different veneer specifications is arranged on the rear side of the installation layer, i.e., the incoming material side, and an integrated PLC control system is provided to automatically match the processing position through the telescopic drive device 52 to realize automatic adjustment and monitoring of the feed speed, slicing depth, and shaving width.

[0030] Furthermore, the clutch conveying device 5 is installed on the frame 1 of the peeling machine 6, which can realize the integration of peeling and shavings and improve the processing efficiency.

[0031] Example 3 On the basis of embodiment 2, the steps of the wood shaving method include: S1, conveying veneer through a feeding device; Different installation 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 installation layer, it is matched to the corresponding installation layer through the telescopic driving device 52.

[0032] S2, trimming the veneer by means of a trimming device; At this time, the pressing belt of the feeding system 2 is in close contact with the conveyor belt.

[0033] S3, shavings through shaving assembly 4; During planing, the angle between the line connecting the upper conveying roller 32 and the lower conveying roller 31 and the horizontal plane is 45-60 degrees, and the minimum distance between the planer 42 and the lower conveying roller 31 is smaller than the minimum distance between the planer 42 and the upper conveying roller 32 .

[0034] If the corresponding specifications of the incoming material cannot be found in the preset installation layers, the planer 42 on the cutter disc 41 of one or more installation layers is disassembled or installed to adjust the number and extension length, adjust the shaving width and speed, and improve the shaving yield rate. Different installation layers are independent of each other. When one installation layer is disassembled or installed, other installation layers can also work, thereby improving work efficiency.

[0035] Furthermore, the device integrates a PLC control system to achieve automatic adjustment and monitoring of the feed speed, slicing depth, and shaving width, thereby improving automation and processing efficiency.
