Description

Technical Field

[0001] This invention relates to the technical field of bamboo processing equipment, specifically to an integrated continuous and precise separation equipment for bamboo reconstituted material units. Background Technology

[0002] Bamboo reconstituted timber is a high-quality bamboo composite material with advantages such as high strength and high stability. Generally, it is produced by splitting bamboo strips to obtain fibrous bamboo veneer, i.e., bamboo reconstituted timber units. These fibrous bamboo veneers are then impregnated with resin, dried, assembled, and pressed to obtain bamboo reconstituted timber. The bamboo strip splitting process mainly includes steps such as flattening, removing nodes, removing the outer green layer, removing the yellow layer, and thinning. The fibrous bamboo veneer obtained from this process is a crucial raw material for bamboo reconstituted timber, and its quality significantly affects the quality of the finished product.

[0003] In the past, each step of the bamboo strip processing was carried out using separate equipment, which required multiple loading, unloading, and transfer between each step. This resulted in relatively low efficiency and relatively high labor intensity in the processing.

[0004] To overcome the above problems, a utility model patent with publication number CN2846074Y and title "Bamboo Removal and Removal Machine" discloses a machine that can continuously complete flattening and removal of bamboo. It can process bamboo into bamboo bundles (i.e., fibrous bamboo veneer) that are horizontally unbroken and vertically loose and interlocked, while removing the bamboo green layer on the surface. This removal machine realizes continuous production, simplifies the process, reduces labor intensity and labor consumption, and improves production efficiency. However, this removal machine has the following problems: (1) The yellow layer and nodes are not removed during the thinning process. The presence of bamboo yellow and nodes will affect the gluing performance and material uniformity of the obtained fibrous bamboo veneer, and thus affect the gluing strength and mechanical strength of the bamboo reconstituted material; (2) Two removal processes are selected to fully remove the bamboo green layer. In the second removal process, it is difficult to avoid removing some bamboo flesh adjacent to the bamboo green layer, which reduces the utilization rate of bamboo to a certain extent.

[0005] The invention patent with publication number CN112109163B, entitled "Bamboo Flattening and Rough Milling Machine," discloses a production line capable of continuously completing feeding, contour-following de-greening, flattening, removing green nodes, flattening, removing yellow nodes, removing bamboo green, removing bamboo yellow, yellow surface thinning, and green surface thinning. The contour-following de-greening device can treat the two sides and edges of the bamboo green surface to compensate for the problem that the de-greening milling cutter cannot reach the two sides and edges after flattening. The green node removal device, yellow node removal device, and yellowing removal device ensure that the obtained fibrous bamboo veneer has uniform material and glue absorption, and gives the fibrous bamboo veneer good bonding properties. However, the following problems exist with this stripping machine: (1) Although it solves the problem of bamboo green being difficult to remove from the sides and edges, after the stripping machine's stripping device removes the green, there are often several unremoved bamboo greens left on the flattened bamboo strips; (2) The structure of the passive stripping wheel makes it easy for the equipment to malfunction due to bamboo strands getting tangled during the stripping process. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated bamboo reconstituted material unit for continuous and precise separation, in order to solve the problem mentioned in the background art that the unwinding wheel of the unwinding device is easily entangled by bamboo fibers, resulting in a high failure rate of the equipment.

[0007] To achieve the above objectives, the present invention provides an integrated continuous and precise separation equipment for bamboo reconstituted material units. The specific technical solution is as follows:

[0008] The device includes at least a stripping device, which comprises a stripping device frame, a conveying roller, a stripping roller corresponding to the conveying roller, and a power mechanism capable of driving the conveying roller and the stripping roller. The stripping roller includes a stripping roller shaft rotatably mounted on the stripping device frame and a plurality of stripping blades spaced apart and fixedly mounted on the stripping roller shaft. The stripping device also includes a cleaning mechanism, which includes a cleaning blade holder fixedly mounted on the stripping device frame and cleaning blades mounted through the cleaning blade holder. The cleaning blades have material-pulling teeth on their cleaning-performing sides, and the material-pulling teeth are inserted between adjacent stripping blades.

[0009] Preferably, the scavenging blade includes a disc base with a central hole and an annular blade disposed on the periphery of the disc base, wherein a plurality of notches are uniformly formed on the annular blade.

[0010] Preferably, the notch is in the shape of a fan-shaped ring.

[0011] Preferably, the number of notches is 6, and the notches of adjacent slitting blades are staggered.

[0012] Preferably, the thickness of the disc substrate is 3mm-5mm, and the cutting angle of the annular blade is 5°-10°.

[0013] Preferably, the feeding teeth are four-sided pyramidal pointed teeth, with the back of the teeth perpendicular to the horizontal plane, and the side of the teeth in clearance fit with the cutting surface of the annular blade.

[0014] Preferably, the gap between the tooth side surface and the cutting edge of the annular blade is 0.5mm-0.8mm, and the tip of the feeding tooth contacts the periphery of the disc substrate.

[0015] Preferably, the device includes a feeding device and a green surface removal device disposed before the stripping device. The feeding device is adapted to feed bamboo strips to the green surface removal device and pre-press the bamboo strips to a specified height. The green surface removal device includes a green surface removal device frame, a first arc-shaped knife group, a second arc-shaped knife group, an adaptive group, and a support roller group. The first arc-shaped knife group and the second arc-shaped knife group are arranged side by side along the conveying direction. The adaptive group is adapted to make the first arc-shaped knife group and the second arc-shaped knife group synchronously adapt to the shape of the green surface of the bamboo strip and sequentially remove the green node part and the green part. The conveying direction of the support roller group is the same as that of the feeding device.

[0016] Preferably, the frame of the green surface removal device includes vertical plates disposed on both sides of the support roller group and a horizontal plate that can be lifted and lowered between the pair of vertical plates. The height of the blade arc apex of the first arc-shaped blade group and the second arc-shaped blade group is limited by the horizontal plate. A first arc-shaped pressure block is disposed behind the first arc-shaped blade group, and a second arc-shaped pressure block is disposed in front of the second arc-shaped blade group. The ends of the first arc-shaped pressure block, the first arc-shaped blade group, the second arc-shaped blade group, and the second arc-shaped pressure block are all fixedly connected to the blade feet. The adaptive group includes multiple adaptive air rods fixedly installed through the vertical plates. The telescopic end of the adaptive air rod is hinged to the blade feet. The telescopic direction of the adaptive air rod is inclined toward the axis of the first arc-shaped blade group and the second arc-shaped blade group.

[0017] Preferably, the second arc-shaped cutter group includes a corrugated arched second cutter body, and a second blade is provided on the front side of the corrugated lower surface of the second cutter body; a third arc-shaped cutter group is also provided between the first arc-shaped cutter group and the second arc-shaped cutter group, the third arc-shaped cutter group includes a corrugated arched third cutter body, and a third blade is provided on the front side of the corrugated lower surface of the third cutter body, the second blade and the third blade are arranged alternately.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] Existing technologies are limited by the stripping capacity of the stripping blades, often requiring stripping one side of the bamboo strip first, then flipping it over to strip the other side. This results in a long production line, requires a lot of factory space, and takes a long time to produce. This embodiment improves the structure of the stripping blades, which has a relatively high stripping capacity and can effectively avoid the problem of bamboo strands tangling. Therefore, it can implement a process of stripping both sides at the same time, making the equipment structure of this application simpler, the production line shorter, and the process simplified.

[0020] The green surface removal device provided in this application can remove the green nodes and green bamboo parts from bamboo strips in a contour-following manner. Compared with the prior art, it has a smaller cutting amount and less bamboo green residue, and can more accurately separate the bamboo green, green nodes and fibrous bamboo veneer. Moreover, the removal of green nodes and bamboo parts is completed in one step, which greatly simplifies the equipment structure and process and shortens the production line thread.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example 1: Refer to Figure 1 The integrated bamboo reconstituted material unit continuous precision separation equipment shown includes, in sequence, a feeding device 2, a bamboo green surface shaping and green removal device 4, a bamboo flattening device 5, a green and yellow node removal device 6, a green and yellow surface removal device 7, a loosening device 1, and a control cabinet.

[0034] The feeding device 2 can be any of the existing technologies, such as including a feeding device frame 21 and a pair of feeding rollers 22 arranged vertically on the feeding device frame 21. There is a set gap between the pair of feeding rollers 22, which is smaller than the height of the bamboo strip 9, so that the bamboo strip 9 can be transported and pre-pressed to a height equal to the set gap during the transport process, denoted as H.

[0035] The bamboo green surface shaping and green removal device 4, the bamboo flattening device 5, the green and yellow node removal device 6, and the green and yellow surface removal device 7 can all be any of the existing technologies, such as the solution disclosed in the invention patent with publication number CN112109163B entitled "Bamboo Flattening and Rough Milling Machine".

[0036] Both the control cabinet and the electrical system utilize existing technologies, such as PLC control cabinets.

[0037] Specifically, refer to Figure 2 As shown, the slack removal device 1 in this embodiment includes a slack removal device frame 11, a conveying roller 12, a slack removal roller 13 corresponding to the conveying roller 12, and a power mechanism 14 capable of driving the conveying roller 12 and the slack removal roller 13.

[0038] Specifically, refer to Figures 2 to 4 As shown, both the conveying roller 12 and the unwinding roller 13 are screwed to the ground and mounted on the frame 11 of the unwinding device. The conveying roller 12 and the unwinding roller 13 are arranged vertically. The conveying roller 12 can be a conventional rubber roller or a steel roller with a mesh surface, as long as it can cooperate with the unwinding roller 13 to convey the bamboo strips 9.

[0039] The unloading roller 13 includes an unloading roller shaft 131 rotatably mounted on the unloading device frame 11, and a plurality of unloading blades 132 fixedly mounted on the unloading roller shaft 131 at intervals. The unloading blades 132 are fixedly mounted on the unloading roller shaft 131 by key connection. The interval between adjacent unloading blades 132 is 0.5mm-1.0mm, which can be spaced by shims, etc., and the two ends are fixed by nuts, etc. The unloading blade 132 includes a disc base 1321 with a central hole 1322 and an annular blade 1323 disposed on the periphery of the disc base 1321. The annular blade 1323 has a plurality of notches 1324 evenly distributed on it. The thickness of the disc base 1321 is 3mm-5mm, and the blade angle of the annular blade 1323 is 5°-10°. After installation, the interval between the disc bases 1321 of adjacent unloading blades 132 is 0.5mm-1.0mm.

[0040] Preferably, the notch 1324 is in the shape of a fan-shaped ring. There are six notches 1324, and the notches 1324 of adjacent shaving blades 132 are staggered. More preferably, the annular blade 1323 on the shaving blade 132 corresponds exactly to and coincides with the notch 1324 on its adjacent shaving blade 132. This structural improvement effectively prevents bamboo fibers from tangling and reduces the equipment's failure rate.

[0041] Combination Figure 5 To further clean up the bamboo fibers or other debris generated during the clearing process, the clearing device 1 in this embodiment also includes a cleaning mechanism 15. The cleaning mechanism 15 includes a cleaning blade holder 151 screwed onto the clearing device frame 11 and cleaning blades 152 mounted on the cleaning blade holder 151. The cleaning blades 152 have multiple material-pulling teeth 153 on their cleaning side, which are inserted between the annular blade edges 1323 of adjacent clearing blades 132.

[0042] The material-drawing tooth 153 is a square pyramidal pointed tooth, with its back surface 1531 perpendicular to the horizontal plane, and its side surface 1532 in clearance fit with the cutting surface of the annular blade 1323. The clearance between the side surface 1532 and the cutting surface of the annular blade 1323 is 0.5mm-0.8mm. The tip 1533 of the material-drawing tooth 153 extends to both sides to form material-drawing tips 1534, which are aligned with the root of the annular blade 1323, so that the material-drawing tips 1534 can contact the periphery of the disc base 1321.

[0043] Existing technologies are limited by the stripping capacity of the stripping blades, often requiring the strips to be stripped on one side first, then flipped over before stripping the other side. This results in a long production line, requires a lot of factory space, and is time-consuming. This embodiment improves the structure of the stripping blade 132, which has a relatively high stripping capacity and can effectively avoid the problem of bamboo strands tangling, thus enabling a process of stripping both sides simultaneously.

[0044] As a supplementary explanation, the structure applicable to adjusting the setting position of the conveyor roller 12, the unloading roller 13 and the cleaning mechanism 15 can adopt any of the existing technologies.

[0045] Figure 6 and Figure 7 The diagram schematically illustrates the structural and power layout of the evacuation device 1 in this embodiment. (Combined with...) Figure 2 As shown, the stripping device 1 in this embodiment includes alternating pairs of first and second stripping rollers. In the first pair, the stripping roller 13 is positioned above and the conveying roller 12 is positioned below; in the second pair, the conveying roller 12 is positioned above and the stripping roller 13 is positioned below. The first pair of stripping rollers can strip the bamboo green surface, and the second pair of stripping rollers can strip the bamboo yellow surface. The alternating arrangement allows for the simultaneous stripping of both the bamboo green and bamboo yellow surfaces within the device 1. Preferably, considering the relatively high hardness of the bamboo green surface, which requires multiple stripping operations, two sets of first stripping roller pairs are placed at the end to ensure the stripping quality of the bamboo green surface.

[0046] With the improvement of the above structure, the stripping device 1 can strip both sides of the bamboo strip 9 in one go without flipping it in the middle, thus making the equipment structure of this embodiment simpler, the production line shorter, and the process simplified. Furthermore, since the larger diameter conveying roller 12 and the smaller diameter stripping roller 13 are alternately arranged, the layout of the stripping device 1 in this embodiment can actually be more compact.

[0047] In terms of power layout, each roller can be equipped with an independent power source, such as a servo motor. In this embodiment, the power mechanism 14 includes multiple servo motors. The servo motor for driving the conveyor roller 12 is located on one side of the evacuation device frame 11, and the servo motor for driving the evacuation roller 13 is located on the other side of the evacuation device frame 11. The rotating rollers of adjacent conveyor rollers 12 are connected by belt drive, and the rotating roller of the active conveyor roller 12 is connected to the output shaft of the servo motor by belt drive; the rotating rollers of adjacent evacuation rollers 13 are connected by belt drive, and the rotating roller of the active evacuation roller 13 is connected to the output shaft of the servo motor by belt drive.

[0048] The method of using the integrated bamboo reconstituted material unit continuous and precise separation equipment in this embodiment is as follows:

[0049] First, bamboo strip 9 is fed into feeding device 2 with the green side facing up, and conveyed along the process direction. During the conveying process, bamboo strip 9 is pre-pressed to a set height, denoted as H.

[0050] Subsequently, bamboo strip 9 enters the bamboo green surface shaping and green removal device 4, bamboo flattening device 5, green and yellow node removal device 6, and green and yellow surface removal device 7 in sequence, and completes the green removal, flattening, removal of green and yellow nodes, and removal of green and yellow surfaces in sequence.

[0051] Afterwards, the bamboo strips 9, after removing the green and yellow parts and flattening them, enter the disintegration device 1, and the green and yellow parts are disintegrated in one step in the disintegration device 1.

[0052] Finally, bamboo strip 9 leaves the equipment of this embodiment to obtain fibrous bamboo veneer.

[0053] Example 2: Refer to Figure 8 , Figure 9 As shown, the difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 sequentially includes a feeding device 2, a green surface removal device 3, a bamboo flattening device 5, a green and yellow node removal device 6, a green and yellow surface removal device 7, a loosening device 1, and a control cabinet. The green and yellow node removal device 6 retains only the yellow node removal function, and the green and yellow surface removal device 7 retains only the yellow surface removal function. The removal of green nodes and the removal of the green bamboo surface are completed in the green surface removal device 3.

[0054] Existing technologies often consider how to remove the outer layer of bamboo from bamboo strips of different thicknesses using equal cutting amounts. To this end, existing technologies employ a technique of first flattening the bamboo strip and then removing the green nodes and outer layer. However, as mentioned earlier, this technique is difficult to completely remove the outer layer of bamboo with relatively small cutting amounts. This is because the outer layer of the flattened bamboo strip is not a completely flat surface, but rather a wavy surface. Therefore, when the cutting amount is small, it is easy to miss some of the outer layer.

[0055] In practice, the feeding device 2 is used to feed bamboo strips 9 to the green surface removal device 3 and pre-press the bamboo strips 9 to a specified height H. Due to the connection between the feeding device 2 and the green surface removal device 3, when part of the bamboo strip 9 remains in the feeding device 2 and part enters the green surface removal device 3, the thickness of the bamboo strip 9 in both devices 2 and 3 is always H. Therefore, regardless of the thickness of the bamboo strip 9 entering the equipment, the feeding device 2 will pre-press it to a height of H. After that, the green surface removal device 3 only needs to conform to the shape of the bamboo strip 9 surface, without needing to consider the actual thickness of the bamboo strip 9.

[0056] After discovering this problem and phenomenon, the inventors proposed the green surface removal device 3 of this embodiment, which includes a green surface removal device frame 31, a first arc-shaped blade group 32, a second arc-shaped blade group 33, an adaptive group 34, and a support roller group 35. The first arc-shaped blade group 32 and the second arc-shaped blade group 33 are arranged side by side along the conveying direction. The adaptive group 34 is adapted to make the first arc-shaped blade group 32 and the second arc-shaped blade group 33 simultaneously adapt to the shape of the green surface of the bamboo strip 9 and sequentially remove the green node part and the green part. The conveying direction of the support roller group 35 is the same as that of the feeding device 2. Those skilled in the art know that in order to prevent the support roller group 35 from affecting the operation of the adaptive group 34, the support roller group 35 has a relatively small width.

[0057] The frame 31 of the bamboo strip removal device includes vertical plates 311 disposed on both sides of the support roller group 35 and a horizontal plate 312 that can be raised and lowered between the pair of vertical plates 311. The height of the blade arc apex of the first arc-shaped blade group 32 and the second arc-shaped blade group 33 is limited by the horizontal plate 312. In other words, by controlling the distance between the support roller group 35 and the horizontal plate 312 to the sum of the pre-pressing height H and the thickness of the arc-shaped blade groups 32 and 33, and then subtracting the amount of chips, the same amount of cutting can be performed on bamboo strips 9 of any thickness.

[0058] In this embodiment, a first arc-shaped pressure block 36 is provided behind the first arc-shaped blade assembly 32 (behind the conveying direction, i.e., towards the feeding device 2), and a second arc-shaped pressure block 37 is provided in front of the second arc-shaped blade assembly 33. The ends of the first arc-shaped pressure block 36, the first arc-shaped blade assembly 32, the second arc-shaped blade assembly 33, and the second arc-shaped pressure block 37 are all fixedly connected to the blade foot 38. The adaptive assembly 34 includes multiple adaptive air rods fixedly installed through the vertical plate 311. The fixing part of the adaptive air rod is grounded and installed on the inner wall of the vertical plate 311 through a cylinder seat screw. The extension end of the adaptive air rod is hinged to the blade foot 38. The extension direction of the adaptive air rod is inclined towards the axis of the first arc-shaped blade assembly 32 and the second arc-shaped blade assembly 33, for example, inclined at 40°.

[0059] With the improvement of the above structure, the top of the arc-shaped blade assembly 32, 33 is limited by the horizontal plate 312, and the blade foot 38 is subjected to the force of the adaptive air rod so that its arc-shaped blade body is always in contact with the bamboo green surface of the bamboo strip 9. Thus, it is possible to remove the green nodes and bamboo green parts of the bamboo strip 9 in a contour-following manner. Moreover, compared with the existing technology, the cutting amount is smaller and the bamboo green residue is less.

[0060] Preferably, refer to Figure 10 , Figure 11As shown, the second arc-shaped cutter group 33 includes a corrugated arched second cutter body 331, and a second blade 332 is provided on the front side of the corrugated lower surface of the second cutter body 331. A third arc-shaped cutter group 39 is also provided between the first arc-shaped cutter group 32 and the second arc-shaped cutter group 33. The third arc-shaped cutter group 39 includes a corrugated arched third cutter body 391, and a third blade 392 is provided on the front side of the corrugated lower surface of the third cutter body 391. The second blade 332 and the third blade 392 are arranged alternately.

[0061] With the improvement of the above structure, the second arc-shaped blade group 33 and the third arc-shaped blade group 39 have stronger surface adaptability, and the bamboo green part can be completely removed.

[0062] In a preferred embodiment, a limiting ring is provided on the feeding roller of the feeding device 2. The limiting ring can determine the position of the bamboo strip 9 during feeding, so that the bamboo strip 9 can be aligned with the green surface removal device 3 during the conveying process.

[0063] In a preferred embodiment, multiple sets of green surface removal devices 3 can be provided, and multiple sets of limiting rings can be correspondingly provided on the feed roller of the feeding device 2. This embodiment, through improvements to the structure of the loosening roller 13, achieves a higher loosening capacity, enabling the simultaneous loosening of multiple bamboo strips 9. Simultaneously, the loosening device 1 in this embodiment does not require a flipping action, so its processing is not limited to one bamboo strip 9 at a time, resulting in higher work efficiency and processing capacity per cycle.

[0064] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
