Description

Technical Field

[0001] The invention belongs to the technical field of bamboo processing, and in particular relates to a bamboo green removal device and bamboo green and yellow removal equipment. Background Art

[0002] Bamboo is the main trunk of a perennial natural plant, boasting a short growth cycle and excellent mechanical properties. However, it's well known that bamboo consists of three components, from the outside in: green bamboo, fleshy bamboo, and yellow bamboo. The green bamboo is covered in wax and silica, while the yellow bamboo contains multiple layers of highly lignified stone cells. This results in the green and yellow bamboo having extremely poor wettability with water and adhesives, significantly impacting treatments such as anti-corrosion, mildew resistance, and gluing, thus affecting the bamboo's secondary processing. Therefore, the first step in bamboo processing is to remove the green and yellow bamboo.

[0003] At present, the bamboo degreening equipment on the market mainly uses two methods to remove the bamboo greens: tool cutting and scraping and roller grinding.

[0004] For example, devices such as CN204487724U, CN101502974A and CN111571742A use cutters to cut bamboo greens. However, due to the irregular shape and large taper of bamboo itself, the cutters in such devices often cannot completely fit the shape of the bamboo when removing the bamboo greens. This results in: if the cutting depth is insufficient (the thickness of the bamboo greens in the original bamboo is generally 0.5 mm), the bamboo greens cannot be completely removed; if the cutting depth is too great, part of the bamboo flesh will be removed together with the bamboo greens, resulting in material waste; at the same time, the high-hardness bamboo nodes are easy to damage the cutters, resulting in a limited tool life.

[0005] For example, equipment such as CN104400858B removes bamboo green by roller grinding. However, due to the irregular shape of bamboo itself, large taper, and the presence of bamboo nodes, the roller may not be able to completely fit the shape of the bamboo, and there are also problems of uneven grinding or over-grinding. At the same time, due to the low surface hardness of fresh raw bamboo, the object for bamboo green grinding is mostly fresh raw bamboo, but fresh raw bamboo has a high moisture content. When using roller grinding, the debris generated by grinding will stick to the rough roller surface, thereby affecting the problem of reduced grinding efficiency.

[0006] Therefore, developing a bamboo green removal equipment that can adapt to the shape of original bamboo and has high bamboo green removal efficiency is of great significance for the secondary processing of bamboo. Summary of the Invention

[0007] The invention aims to provide a bamboo green removal device and bamboo green and yellow removal equipment, which can fully adapt to the shape of the original bamboo, not only has high bamboo green removal efficiency, but also does not cause material waste.

[0008] In order to achieve the above-mentioned object of the invention, the technical solution of the present invention is:

[0009] A bamboo degreening device, comprising:

[0010] A rotating drum is formed with a material transfer channel, and a plurality of bamboo green polishing air bags are provided on the inner wall of the material transfer channel, and all the bamboo green polishing air bags are connected to the air inlet formed on the peripheral wall of the rotating drum;

[0011] An air supply component, the air outlet end of which is rotatably connected to the rotating cylinder and sealed to supply air to the bamboo green polishing air bag through the air inlet;

[0012] The bamboo green polishing airbag has an uninflated state for facilitating the raw bamboo to enter the material passing channel and an inflated state for tightly holding the raw bamboo.

[0013] The bamboo material green removal device of the present invention utilizes a rotating cylinder to drive a green bamboo polishing airbag to polish the original bamboo in the feeding channel to remove the green bamboo, and the air supply component is used to supply air to the green bamboo polishing airbag; before polishing, the green bamboo polishing airbag is in an uninflated state so that the original bamboo can enter the feeding channel; after the original bamboo enters the feeding channel, the air supply component inflates the green bamboo polishing airbag, and the green bamboo polishing airbag will hold the original bamboo in the feeding channel after expansion; then when the rotating cylinder rotates, the green bamboo polishing airbag also rotates therewith (because the air supply component is connected to the rotating cylinder for rotation, it will not rotate with the rotating cylinder, but maintain its position unchanged), and the green bamboo surface of the original bamboo is polished during the rotation process. During the polishing process, the green bamboo polishing airbag can fully adapt to the shape of the original bamboo, completely and evenly wrap the original bamboo, not only with high green bamboo removal efficiency, but also without polishing off the bamboo flesh to cause material waste.

[0014] The arrangement of the bamboo green polishing airbags in the rotating drum can be arbitrary, for example, it can be: the bamboo green polishing airbags have at least one group arranged along the axial direction of the material transfer channel, each group of bamboo green polishing airbags has at least two arranged along the circumference of the material transfer channel, and each bamboo green polishing airbag is strip-shaped and extends linearly or spirally along the axial direction of the material transfer channel;

[0015] Alternatively, the bamboo green grinding airbags are in an annular shape (circular or elliptical), and all the bamboo green grinding airbags are arranged axially in the feed channel.

[0016] The present invention has no special requirements for this, but no matter which method is used, the goal should be to minimize the number of gaps formed by adjacent bamboo green grinding airbags in the axial direction of the feed channel, that is, to ensure that: the bamboo green grinding airbags do not form grinding gaps in the circumferential direction of the feed channel or the formed grinding gaps are not closed in the circumferential direction, because during the bamboo green grinding process, the closed grinding gaps formed in the circumferential direction of the feed channel will form grinding holes on the original bamboo, and the complete removal of the bamboo green cannot be achieved.

[0017] Whether a grinding gap is formed is mainly determined by the number and arrangement of the bamboo green grinding airbags, namely:

[0018] 1. When only one cylindrical bamboo green grinding airbag is provided in the feed channel (completely covering the feed channel), no grinding gap will be formed in the circumferential direction of the feed channel.

[0019] 2. When the bamboo green grinding airbag cannot completely cover the feed channel, each bamboo green grinding airbag needs to be extended linearly or spirally along the axial direction of the feed channel, and the length of each bamboo green grinding airbag is the same as the length of the feed channel; or, two adjacent groups of bamboo green grinding airbags are staggered and arranged in the axial direction of the feed channel; or, an elliptical ring-shaped bamboo green grinding airbag is used. At this time, the grinding gap formed between the two bamboo green grinding airbags is not closed in the circumferential direction of the feed channel, and the influence of the grinding gap can be eliminated in time during the rotation of the bamboo green grinding airbag.

[0020] Preferably, in the bamboo desludging device, the bamboo desludging airbags are detachably connected to the rotating drum, and each bamboo desludging airbag has an abrasive layer on its surface. This allows for replacement of a bamboo desludging airbag with a damaged abrasive layer after a period of use. The abrasive layer can be made of materials such as silicon carbide sand and aluminum oxide sand.

[0021] Because the air supply assembly is rotatably connected to the rotating cylinder, and in order to supply air, the air supply assembly must be set to seal with the rotating cylinder. If the air inlets are distributed in a messy manner, the number of air supply assemblies will increase, and the risk of poor sealing between the air supply assembly and the rotating cylinder will increase.

[0022] Therefore, preferably, in the above-mentioned bamboo material de-greening device, each bamboo material de-greening air bag has at least one air inlet, and each air inlet is concentratedly distributed at one or more circumferential positions of the rotating drum;

[0023] The air supply component has one or more air outlet ends, and each air outlet end is used to supply air to each air inlet located at the same circumferential position.

[0024] After the air inlets are arranged centrally, a small number of air supply components can supply air to each bamboo green polishing airbag. It should be noted that the air inlets at the same circumferential position can be connected to the same bamboo green polishing airbag or to different bamboo green polishing airbags.

[0025] In order to facilitate the connection between the air supply assembly and the rotating drum, and also to facilitate the supply of air to the air inlets at the same circumferential position, preferably, in the above-mentioned bamboo degreening device, one or more annular air supply grooves are formed on the outer circumferential wall of the rotating drum, and the air inlets are arranged at the bottom of the air supply grooves;

[0026] The air supply assembly includes:

[0027] An air supply seal is rotatably connected to the air supply groove and is in sealing engagement with the air supply groove, and an air supply port is formed on the peripheral wall of each air supply seal;

[0028] An air supply branch pipe, the air supply branch pipe being connected to the air supply sealing member in a one-to-one correspondence;

[0029] An air supply main pipe, the air outlet of which is connected to each air supply branch pipe, and the air inlet of which is connected to the air supply source.

[0030] The air supply groove not only facilitates the assembly of the air supply seal, but also ensures the air tightness between the air supply seal and the rotating cylinder; moreover, all air inlets are connected to the air supply groove, so the air supply groove becomes an air supply center, and the air supply component only needs to supply air to the air supply groove through one air supply port, which greatly facilitates the air supply process.

[0031] During the operation of the bamboo green grinding airbag, a large amount of powder chips will accumulate on the surface of the bamboo green grinding airbag and in the material transfer channel. In order to prevent these powder chips from affecting the normal progress of the bamboo green grinding work, it is preferred that in the above-mentioned bamboo material de-greening device, a plurality of chip discharge openings are further formed on the peripheral wall of the rotating cylinder, and the chip discharge openings are arranged in the gaps between adjacent bamboo green grinding airbags;

[0032] The chip removal port is communicated with a chip removal assembly, and the chip removal assembly is rotationally connected to the rotating cylinder and sealed.

[0033] After the chip discharge port is set, the chip discharge assembly can suck the chips out of the chip discharge port by means of negative pressure suction; similarly, the chip discharge assembly is also rotatably connected to the rotating drum so as to maintain its own position unchanged when the rotating drum rotates.

[0034] In the present invention, the chip removal work can be carried out synchronously with the bamboo green grinding work, that is, during the chip removal process, the bamboo green grinding airbag maintains its inflated state to continue grinding; it can also be carried out alternately with the bamboo green grinding process, that is, the bamboo green grinding airbag works at a frequency of "inflated-not inflated-inflated-not inflated", and bamboo green grinding is carried out when inflated, and when not inflated, the bamboo green grinding airbag contracts to make the powder chips adhering to its surface fall off for discharge.

[0035] Preferably, in the above-mentioned bamboo wood degreening device, the chip discharge openings are concentrated at one or more circumferential positions of the rotating cylinder and are different from the circumferential positions of the air inlet.

[0036] One or more annular chip removal grooves are formed on the rotating cylinder, and the air inlet is arranged at the bottom of the chip removal groove;

[0037] The chip removal assembly comprises:

[0038] A chip removal seal, the chip removal seal is rotatably connected to the chip removal groove and is in sealing engagement;

[0039] A chip removal branch pipe, the chip removal branch pipe being connected to the chip removal seal in a one-to-one correspondence;

[0040] A chip removal main pipe, a chip suction end of the chip removal main pipe is connected to each chip removal branch pipe, and a chip removal end of the chip removal main pipe is connected to a negative pressure source.

[0041] Alternating the chip removal openings and air inlets at different circumferential locations on the rotating drum prevents confusion between chip removal and air intake, and also facilitates the setup of the air supply and chip removal assemblies. The principle of setting the chip removal grooves is the same as that of the air supply grooves and will not be elaborated on here.

[0042] In the bamboo degreening device of the present invention, the rotating cylinder is driven to rotate by a driving assembly, which includes support seats arranged at both ends of the rotating cylinder, each support seat is rotatably connected to at least two rollers tangential to the rotating cylinder, and at least one roller is connected to the first circumferential driver.

[0043] Two rollers are positioned on opposite sides of the rotating drum, supporting it while also driving its rotation. The drum's weight creates sufficient friction between it and the rollers. To further ensure the drum remains on the support and maintains sufficient friction with the rollers, an air supply assembly can be positioned above the drum (preferably, a chip removal assembly below it). This fixed air supply assembly applies pressure to the drum. Alternatively, placing additional rollers above the drum to compress it can achieve the same goal.

[0044] In order to further improve the degree of automation of the equipment, preferably, in the above-mentioned bamboo degreening device, a feeding assembly for conveying raw bamboo to the rotating drum is provided upstream of the rotating drum;

[0045] A traction assembly is provided downstream of the rotating drum for keeping the raw bamboo in the rotating drum in a constant circumferential position and driving the raw bamboo forward. The traction assembly includes:

[0046] traction bracket;

[0047] a first traction gripper slidably mounted on the traction bracket and used for holding the raw bamboo;

[0048] a first linear drive for driving the first traction gripper to slide;

[0049] Sensors for detecting raw bamboo;

[0050] A controller is used to receive signals from the sensor and control the operation of the first linear drive and the first traction gripper according to the signals.

[0051] Among them, the feeding component can adopt a raw bamboo conveyor belt, and the width of the raw bamboo conveyor belt can be equivalent to the inner diameter of the feeding channel. When the bamboo green grinding airbag is not inflated, the raw bamboo on the raw bamboo conveyor belt can enter the feeding channel by itself, and the workers only need to place the raw bamboo on the raw bamboo conveyor belt.

[0052] On the one hand, the traction assembly can use the first traction gripper to hold the original bamboo tightly, so that the original bamboo maintains an unchanged circumferential position and does not rotate with the rotating drum; on the other hand, the first traction gripper can also slide the original bamboo during the bamboo green grinding process, so that the part that has completed the green grinding of the bamboo green is pulled out of the rotating drum, and the part that has not been ground enters the rotating drum. The equipment has a high degree of automation and saves labor costs.

[0053] The present invention also provides a bamboo material green and yellow removal device, which comprises the above-mentioned bamboo material green removal device and a bamboo material yellow removal device provided downstream of the bamboo material green removal device;

[0054] The bamboo yellowing removal device is arranged upstream or downstream of the bamboo green removal device, or the bamboo yellowing removal device is arranged at the center of the rotating cylinder.

[0055] That is, in the bamboo material green and yellowing removal equipment, the green can be removed first and then the yellow, or the yellow can be removed first and then the green, or the green and yellow removal operations can be implemented simultaneously.

[0056] Preferably, in the above-mentioned bamboo material green and yellow removal equipment, the bamboo material yellow removal device comprises:

[0057] A yellowing removal bracket, wherein the yellowing removal bracket is provided with an original bamboo fixing component for fixing the original bamboo;

[0058] Rotating a rotating rod connected to the yellowing removal bracket;

[0059] a circumferential drive for driving the rotating shaft to rotate;

[0060] A bamboo yellow polishing air bag provided on the outer peripheral wall of the rotating rod;

[0061] An approach component is used to drive at least one of the original bamboo fixing mechanism and the rotating rod to move toward the other.

[0062] The present invention employs a bamboo shavings polishing airbag mounted on a rotating rod. The airbag is then introduced into the interior of the original bamboo. As the rod rotates, the airbag rotates accordingly, thereby polishing and removing the shavings from the original bamboo. The soft and elastic properties of the airbag allow it to completely conform to the shape of the original bamboo's internal cavity after inflation. Therefore, the shape of the original bamboo being processed is not required. There is no need to cut a straight bamboo tube with a constant inner diameter from the original bamboo before polishing. This not only increases the efficiency of bamboo shavings removal, but also prevents the polishing of the bamboo flesh, eliminates the need to remove oddly shaped bamboo segments, and eliminates material waste.

[0063] At the same time, a tip capable of breaking the internode septum of the original bamboo can be provided at one end of the rotating rod facing the original bamboo fixing assembly, thereby reducing resistance to the bamboo yellow polishing work of the bamboo yellow polishing airbag.

[0064] As a further preference, the above-mentioned bamboo yellowing removal device is arranged downstream of the bamboo green removal device to realize the assembly line operation of green removal, transverse partition breaking and yellowing removal; at this time, the yellowing removal bracket and the traction bracket can be directly merged to simplify the structure; the traction component can also be used to deliver the original bamboo to the original bamboo fixing component.

[0065] Compared with the prior art, the beneficial effects of the present invention are embodied in:

[0066] (1) The bamboo material green removal device of the present invention utilizes a rotating cylinder to drive a green bamboo polishing airbag to polish the original bamboo in the feeding channel to remove the green bamboo, and the air supply component is used to supply air to the green bamboo polishing airbag; before polishing, the green bamboo polishing airbag is in an uninflated state so that the original bamboo can enter the feeding channel; after the original bamboo enters the feeding channel, the air supply component inflates the green bamboo polishing airbag, and the green bamboo polishing airbag will hold the original bamboo in the feeding channel after expansion; then when the rotating cylinder rotates, the green bamboo polishing airbag also rotates (because the air supply component is connected to the rotating cylinder, it will not rotate with the rotating cylinder, but keep its position unchanged), and the green bamboo surface of the original bamboo is polished during the rotation process. During the polishing process, the green bamboo polishing airbag can fully adapt to the shape of the original bamboo and completely and evenly wrap the original bamboo, which not only has a high efficiency in removing green bamboo, but also does not polish off the bamboo flesh to cause material waste.

[0067] (2) The present invention concentrates the air inlets at one or more circumferential positions of the rotating cylinder, so that air can be supplied to each bamboo green polishing air bag using a small number of air supply components, avoiding the increased risk of loose sealing between the air supply components and the rotating cylinder due to an excessive number of air supply components.

[0068] (3) The present invention provides one or more annular air supply grooves on the outer peripheral wall of the rotating cylinder, and the air inlet is provided at the bottom of the air supply groove; the air supply groove is not only convenient for the assembly of the air supply seal, but also can better ensure the air tightness between the air supply seal and the rotating cylinder; moreover, all the air inlets are connected to the air supply groove, so the air supply groove becomes an air supply center, and the air supply component only needs to supply air to the air supply groove through one air supply port, which greatly facilitates the air supply process.

[0069] (4) The bamboo material de-greening device of the present invention also includes a chip removal component, which is connected to a chip removal port provided on the peripheral wall of the rotating cylinder, so that the powder chips generated during the bamboo material de-greening process can be discharged in time to prevent the powder chips from affecting the normal progress of the bamboo material de-greening work.

[0070] (5) In the present invention, a feeding assembly for conveying raw bamboo to the rotating drum is provided upstream of the rotating drum. The feeding assembly can be a raw bamboo conveyor belt. The width of the raw bamboo conveyor belt can be equivalent to the inner diameter of the feeding channel. When the bamboo green grinding airbag is not inflated, the raw bamboo on the raw bamboo conveyor belt can enter the feeding channel by itself, and the workers only need to place the raw bamboo on the raw bamboo conveyor belt.

[0071] (6) In the present invention, a traction assembly is further provided downstream of the rotating drum. On the one hand, the traction assembly can use the first traction gripper to hold the raw bamboo tightly so that the raw bamboo maintains an unchanged circumferential position and does not rotate with the rotating drum; on the other hand, the first traction gripper can also slide the raw bamboo during the green bamboo grinding process, so that the part that has been finished green bamboo is pulled out of the rotating drum, and the part that has not been ground enters the rotating drum. The equipment has a high degree of automation and saves labor costs.

[0072] (7) The present invention sets a bamboo yellow polishing airbag on the rotating rod, and uses the rotating rod to bring the bamboo yellow polishing airbag into the interior of the original bamboo. When the rotating rod rotates, the bamboo yellow polishing airbag rotates accordingly, thereby polishing and removing the bamboo yellow inside the original bamboo. The soft and elastic characteristics of the bamboo yellow polishing airbag enable the bamboo yellow polishing airbag to completely fit the shape of the internal cavity of the original bamboo after inflation. Therefore, there are no requirements for the shape of the original bamboo to be processed. Before polishing, there is no need to cut out a straight bamboo tube with a constant inner diameter from the original bamboo. Not only is the bamboo yellow removal efficiency high, but the bamboo flesh will not be polished off, and there is no need to remove bamboo segments with strange shapes, which will not cause material waste.

[0089] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0090] Example 1

[0091] like Figure 1 and Figure 2As shown, the present embodiment is a bamboo green removal device, comprising a rotating cylinder 1, in which a feeding channel 11 is formed, and a plurality of bamboo green grinding air bags 2 for grinding and removing the green bamboo from the raw bamboo 100 are detachably mounted on the inner wall of the feeding channel 11; a feeding assembly 3 for conveying the raw bamboo to the feeding channel 11 is provided upstream of the rotating cylinder 1, and a traction assembly 4 for keeping the raw bamboo in the feeding channel 11 in an unchanged circumferential position and driving the raw bamboo forward is provided downstream of the rotating cylinder 1.

[0092] Among them, the feeding component 3 includes a feeding bracket 31, on which a raw bamboo conveyor belt 32 runs back and forth. The width of the raw bamboo conveyor belt 32 is preferably set to be equivalent to the inner diameter of the rotating drum 1 or the transfer channel 11, so that the raw bamboo can enter the transfer channel 11 autonomously under the push of the raw bamboo conveyor belt 32; baffles 33 are also provided on the opposite sides of the raw bamboo conveyor belt 32.

[0093] The bamboo green polishing airbag 2 in the feeding channel 11 is made of a polymer elastic material, such as silica gel, rubber, etc., and is made of silicon carbide sand, aluminum oxide sand, etc. as the surface abrasive, so it has an uninflated state (such as Figure 5 as shown) and inflation state (as shown) Figure 6 Before the raw bamboo enters the feeding channel 11, the green bamboo polishing airbag 2 is in an uninflated state, which facilitates the raw bamboo to enter the feeding channel 11; after the raw bamboo enters the feeding channel 11, the green bamboo polishing airbag 2 is inflated by the air supply component 5 and wraps the raw bamboo (as shown). Figure 7 shown).

[0094] When the rotating drum 1 rotates, the bamboo green grinding airbag 2 also rotates accordingly, and the original bamboo maintains an unchanged circumferential position under the control of the traction component 4 or manpower. Therefore, the bamboo green grinding airbag 2 can completely and evenly wrap the original bamboo while fully adapting to the shape of the original bamboo, and perform bamboo green grinding and removal work on the surface of the original bamboo.

[0095] like Figure 1 Shown, combined Figure 3 and Figure 4 It can be seen that in this embodiment, the rotating drum 1 is in the shape of an elongated cylinder, and the bamboo green polishing airbags 2 in the feed channel 11 have four pieces that are evenly arranged circumferentially around the feed channel 11. Each bamboo green polishing airbag 2 is strip-shaped and extends axially along the feed channel 11. The bamboo green polishing airbag 2 extends axially along the feed channel 11 in various ways, which can be a linear extension (adopted in this embodiment) or a spiral extension.

[0096] Along the circumference of the feed channel 11, only one group of bamboo green grinding airbags 2 can be set (that is, one bamboo green grinding airbag 2 extends directly from the head end of the rotating cylinder 1 to the tail end of the rotating cylinder 1); or multiple groups can be set. In this case, the bamboo green grinding airbags 2 at adjacent axial positions are preferably staggered to eliminate the gap formed by adjacent bamboo green grinding airbags 2 in the circumference of the feed channel 11.

[0097] When multiple bamboo green polishing airbags 2 are required to be arranged in the feed channel 11, polishing gaps may be formed between adjacent bamboo green polishing airbags 2. However, since the bamboo green polishing airbags 2 rotate with the rotating drum 1, the polishing gaps extending axially along the feed channel 11 do not affect the polishing process, but the polishing gaps extending circumferentially along the feed channel 11 may affect it. Therefore, it is necessary to ensure that no polishing gaps are formed in the circumferential direction of the feed channel 11 or that the polishing gaps formed are not closed in the circumferential direction, because during the bamboo green polishing process, closed polishing gaps formed in the circumferential direction of the feed channel 11 will form polishing holes in the original bamboo, making it impossible to completely remove the bamboo yellow.

[0098] Whether a grinding gap is formed is mainly determined by the number and arrangement of the bamboo green grinding airbags, namely:

[0099] 1. When only one cylindrical bamboo green polishing airbag 2 is provided in the material transfer channel 11 (completely covering the material transfer channel 11 ), no polishing gap is formed in the circumferential direction of the material transfer channel 11 .

[0100] 2. When the bamboo green polishing airbag 2 cannot completely wrap the feed channel 11, each bamboo green polishing airbag 2 needs to be extended linearly or spirally along the axial direction of the feed channel 11, and the length of each bamboo green polishing airbag 2 is the same as the length of the feed channel; or, two adjacent groups of bamboo green polishing airbags 2 are staggered in the axial direction of the feed channel 11; or, an elliptical ring-shaped bamboo green polishing airbag 2 is used. At this time, the polishing gap formed between the two bamboo green polishing airbags 2 is not closed in the circumferential direction of the feed channel 11, and the influence of the polishing gap can be eliminated in time during the rotation of the bamboo green polishing airbag 2.

[0101] like Figure 3 and Figure 8 As shown, a plurality of annular air supply grooves 12 are formed on the peripheral wall of the rotating cylinder 1, and the air supply grooves 12 are evenly arranged along the axial direction of the rotating cylinder 1; a plurality of air inlets 13 connected to the feed channel 11 are opened in each air supply groove 12, and the air nozzle of the bamboo green polishing airbag 2 installed in the feed channel 11 is sealedly connected to the corresponding air inlet 13 to supply air to the bamboo green polishing airbag 2.

[0102] Depend on Figure 3 and Figure 8It can be seen that in each air supply groove 12, four groups of air inlets 13 corresponding to the four bamboo green polishing air bags 2 are opened, and each group of air inlets 13 has one, two or more. The present invention has no special requirements for this, as long as it is ensured that the air supply component 5 can quickly supply air to the bamboo green polishing air bags 2.

[0103] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the rotation of the rotating drum 1 is driven by a driving assembly 6, which includes support seats 61 provided at both ends of the rotating drum 1, and each support seat 61 is rotatably connected to two pairs of rollers 62 tangential to the rotating drum 1, and the two pairs of rollers 62 are oppositely arranged on both sides of the rotating drum 1; on the one hand, the rollers 62 play a role in supporting the rotating drum 1, and on the other hand, the weight of the rotating drum 1 ensures sufficient friction between it and the rollers 62. At this time, as long as one or more of the rollers 62 are connected to the first circumferential driver (not shown in the figure), the rotating drum 1 can be driven to rotate.

[0104] However, since the rotating drum 1 is constantly rotating during operation, the air supply assembly 5 needs to maintain its position unchanged. Figure 9 Shown, combined Figure 1 and Figure 3 It can be seen that in this embodiment, the air supply component 5 is configured to include an air supply seal 51 that is rotatably connected to and sealed with the air supply groove 12. An air supply port is formed on the peripheral wall of each air supply seal 51, and a air supply branch pipe 52 is sealed and connected to the air supply port. All air supply branch pipes 52 are connected to the air supply main pipe 53, and the air supply source connected to the air supply main pipe 53 supplies air to all air supply grooves 12 at the same time; and after the gas enters the air supply groove 12, since all the air inlets 13 are connected to the air supply groove 12, air can be supplied to all the air inlets 13 at the same time.

[0105] In order to further improve the sealing performance between the air supply seal 51 and the air supply groove 12, as shown in FIG. Figure 3 、 Figure 8 and Figure 9 As shown, sealing grooves 14 are provided on the two opposite side walls of the air supply groove 12. At the same time, a pair of avoidance grooves 54 are correspondingly formed on the air supply branch pipe 52. In this way, a sealing ring (not shown in the figure) is placed between the sealing groove 14 and the avoidance groove 54. By clamping the sealing ring with the sealing groove 14 and the avoidance groove 54, the sealing performance can be well ensured to avoid air leakage.

[0106] During the operation of the bamboo green grinding airbag 2, a large amount of dust will accumulate on the surface of the airbag and in the feeding channel 11. In order to prevent these dusts from affecting the normal operation of the bamboo green grinding work, Figure 1 、 Figure 3 and Figure 8 As shown, the peripheral wall of the rotating drum 1 is provided with a plurality of annular chip removal grooves 15 arranged along the axial direction of the rotating drum 1. Each chip removal groove 15 is spaced apart from each air supply groove 12. The bottom of each chip removal groove 15 is provided with a plurality of chip removal ports 16 connected to the feed channel 11. Figure 3 It can be seen that the chip discharge port 16 is provided in the gap between adjacent bamboo green grinding air bags 2 and is arranged circumferentially around the rotating cylinder 1 .

[0107] After the chip discharge port 16 is provided, the powder chips generated during the bamboo green grinding process can be discharged as quickly as possible. To further promote the discharge of powder chips, this embodiment also provides a chip discharge assembly 7. The structure of the chip discharge assembly 7 is similar to that of the air supply assembly 5. It includes a chip discharge seal 71 that is rotatably connected to the chip discharge groove 15 and seals the chip discharge groove 15. Each chip discharge seal 71 is sealed and connected to a chip discharge branch pipe 72. All chip discharge branch pipes 72 are connected to the chip suction end of the chip discharge main pipe 73, and the chip discharge end of the chip discharge main pipe 73 is connected to a negative pressure source (not shown in the figure).

[0108] Depend on Figure 3 and Figure 8 As shown, sealing grooves 14 are also formed on the two opposite side walls of the chip removal groove 15. Correspondingly, an avoidance groove is also formed on the chip removal branch pipe 72. A sealing ring is placed between the sealing groove 14 and the avoidance groove. By clamping the sealing ring with the sealing groove 14 and the avoidance groove, the sealing performance can be well ensured to avoid air leakage.

[0109] The chip removal work can be carried out synchronously with the bamboo green grinding work, that is, during the chip removal process, the bamboo green grinding airbag 2 maintains its inflated state to continue grinding; it can also be carried out alternately with the bamboo green grinding process, that is, the bamboo green grinding airbag 2 works at a frequency of "inflated-not inflated-inflated-not inflated", and bamboo green grinding is carried out when inflated, and when not inflated, the bamboo green grinding airbag 2 contracts to make the powder chips adhering to its surface fall off for discharge.

[0110] In this embodiment, the air supply component 5 is arranged above the rotating cylinder 1. At this time, the air supply component 5 maintained in a fixed position can apply a certain pressure to the rotating cylinder 1, further ensuring that the rotating cylinder 1 remains on the support seat 61 and can generate sufficient friction between it and the roller 62; and the chip removal component 7 is arranged below the rotating cylinder 1 to facilitate the discharge of powder and chips.

[0111] The rotating drum 1 and the bamboo green grinding airbag 2 are used to grind the surface of the raw bamboo green during the rotation of the rotating drum 1. During the grinding process, it is necessary to ensure that the raw bamboo in the feeding channel 11 maintains an unchanged circumferential position. Therefore, in this embodiment, a traction component 4 is provided downstream of the rotating drum 1. Figure 1 and Figure 2As shown, the traction assembly 4 includes a traction bracket 41, and a horizontal slide groove 411 is provided on each of the opposite sides of the traction bracket 41. The tail ends of a pair of adjacent first traction grippers 42 are respectively slidably installed in the corresponding horizontal slide grooves 411; the first traction grippers 42 are driven by a first linear drive (not shown in the figure) to slide horizontally along the traction bracket 41. The first traction grippers 42 can not only hold the original bamboo tightly during the bamboo green grinding process to keep its circumferential position unchanged, but also can gradually pull the original bamboo part that has completed the bamboo green grinding out of the rotating drum 1, and the equipment has a higher degree of automation.

[0112] Among them, the operations of the first traction gripper 42 and the first linear drive are both controlled by the controller. Infrared sensors for detecting raw bamboo are also installed on the opposite sides of the traction bracket 41. When the infrared sensor detects that the head end of the raw bamboo extends out of the feeding channel 11, it sends a signal to the controller. After receiving the signal, the controller starts the first linear drive. The first linear drive will bring the first traction gripper 42 in an open state to the head end of the raw bamboo. The controller will control the first traction gripper 42 to close and hold the raw bamboo again, and then the first linear drive drives the first traction gripper 42 to slide downstream at a predetermined speed or frequency to gradually pull the raw bamboo part that has completed bamboo green polishing out of the rotating cylinder 1.

[0113] Since the first traction gripper 42 holds the head end of the original bamboo, in order to prevent the tail end of the bamboo from falling off when the whole original bamboo leaves the rotating drum 1 after completing the bamboo green grinding, a first auxiliary gripper 43 is also installed at the end of the traction bracket 41 close to the rotating drum 1. The first auxiliary gripper 43 is used to grasp the tail end of the bamboo to prevent the tail end of the bamboo from falling off and causing unnecessary bending, and also facilitates delivery to the downstream process (when the first auxiliary gripper 43 holds the bamboo, the first traction gripper (42) can return and then hold and pull the bamboo, thereby delivering the bamboo to the downstream process).

[0114] The first auxiliary grip 43 can be slidably mounted on the traction bracket 41 like the first traction grip 42. In this case, the first auxiliary grip 43 is preferably configured to be able to hold the bamboo like the first traction grip 42. Alternatively, the first auxiliary grip 43 can remain in position unchanged. In this case, the first auxiliary grip 43 is preferably configured not to hold the bamboo, but only to support the bamboo, so as not to affect the first traction grip 42 in pulling the bamboo.

[0115] Furthermore, the first auxiliary gripper 43 may hold the bamboo material only when the tail end of the bamboo material leaves the rotating drum 1, or may hold the bamboo material during the bamboo green grinding process, as long as it is ensured that the traction operation of the first traction gripper 42 is not affected (i.e., if the first auxiliary gripper 43 holds the bamboo material, the first auxiliary gripper 43 must be opened when the first traction gripper 42 performs the traction operation).

[0116] A more preferred approach is that the first auxiliary gripper 43 maintains its position unchanged and does not lock the bamboo when holding it.

[0117] The working principle of the bamboo material degreening device in this embodiment is as follows:

[0118] The worker places the raw bamboo after removing the branches on the raw bamboo conveyor belt 32, and the raw bamboo conveyor belt 32 conveys the raw bamboo into the feeding channel of the rotating drum 1. At this time, the bamboo green polishing airbag 2 in the feeding channel is in an uninflated state;

[0119] When the raw bamboo head end passes through the feeding channel 11, the infrared sensor detects the raw bamboo head end and sends a signal to the controller. After receiving the signal, the controller starts the first linear drive, and the first linear drive brings the first traction gripper 42 in the open state to the raw bamboo head end. The controller controls the first traction gripper 42 to close and hold the raw bamboo again; at the same time, the controller starts the air supply source, and the air enters the air supply grooves 12 through the air supply main pipe 53 and the air supply branch pipes 52, and enters the corresponding bamboo green grinding airbags 2 through the air inlets 13; after the bamboo green grinding airbags 2 completely wrap the raw bamboo, the controller starts the first circumferential drive, and the first circumferential drive drives the rotating drum 1 to rotate through the roller 62, and the bamboo green grinding airbags 2 grind the surface of the raw bamboo during the rotation process;

[0120] During the grinding process, the negative pressure source is activated, and the powder chips in the feeding channel 11 are sucked by the negative pressure and discharged through the chip discharge port 16, the chip discharge branch pipe 72 and the chip discharge main pipe 73;

[0121] During the green bamboo grinding process, the first linear drive drives the first pulling gripper 42 to slide downstream at a predetermined speed or frequency, so as to gradually pull the green bamboo portion that has been green-ground out of the rotating drum 1; until the green bamboo on the entire surface of the original bamboo is completely ground and the entire original bamboo leaves the rotating drum 1; at this time, the controller controls the first auxiliary gripper 43 to hold the tail end of the bamboo tightly to prevent the bamboo from being bent unnecessarily due to the tail end suddenly falling off, and to facilitate delivery to the downstream process;

[0122] During the operation of the equipment, it is sufficient to replace the bamboo green polishing airbag 2 regularly.

[0123] Example 2

[0124] like Figure 10 As shown, this embodiment provides a bamboo green and yellow removal device, which includes a bamboo green removal device A that is the same as that in Example 1, and also includes a bamboo yellow removal device B arranged downstream of the bamboo green removal device A.

[0125] Depend on Figure 10It can be seen that the bamboo de-yellowing device B includes a de-yellowing bracket, which is integrally arranged with the traction bracket 41. The following description will directly use the traction bracket 41; the traction bracket 41 is provided with a raw bamboo fixing component B1 for fixing the raw bamboo, a de-yellowing mechanism B2 for de-yellowing the raw bamboo, and an approaching component for driving at least one of the raw bamboo fixing mechanism B1 and the de-yellowing component B2 to move toward the other; the approaching component is used to automatically move the raw bamboo fixed by the raw bamboo fixing component B1 and the de-yellowing component B2 closer to each other, thereby achieving a high degree of automated bamboo yellowing removal.

[0126] Among them, the approach mechanism can drive the original bamboo fixing component B1 to move toward the yellowing removal component B2 (in this case, the yellowing removal component B2 can maintain its position unchanged), or it can drive the yellowing removal component B2 to move toward the original bamboo fixing component B1 (in this case, the original bamboo fixing component B1 can maintain its position unchanged), or it can simultaneously drive the original bamboo fixing component B1 and the yellowing removal component B2 to move toward each other. This embodiment has no special requirements for this.

[0127] The following will continue to introduce the structure of the bamboo yellowing removal device by taking the approach mechanism driving the original bamboo fixing component B1 to move toward the yellowing removal component B2 as an example.

[0128] like Figure 10 As shown, the raw bamboo fixing assembly B1 of this embodiment includes at least one second traction gripper B11 slidably mounted on the traction bracket 41, and the approach mechanism includes a second linear drive (not shown in the figure) for driving the second traction gripper B11 to slide along the traction bracket 41. The second traction gripper B11 and the second linear drive are both connected to the controller.

[0129] like Figure 10 As shown, a pair of second traction grippers B11 are slidably installed on opposite sides of the traction bracket 41. The pair of second traction grippers B11 are used to hold the raw bamboo from two directions, which can ensure that the second traction grippers B11 exert sufficient gripping force on the raw bamboo, thereby avoiding instability of the raw bamboo during the yellowing process.

[0130] The second linear actuator can be a pneumatic cylinder or a hydraulic cylinder. By fixedly connecting the piston of the pneumatic cylinder or the hydraulic cylinder to the tail end of the second traction gripper B11, the second traction gripper B11 can be driven to slide along the horizontal slide groove 411.

[0131] In order to ensure that the original bamboo is kept in a horizontal state on the traction support 41 so as to perform the yellowing operation, Figure 10 As shown, in this embodiment, two second auxiliary grippers B12 are further provided on the traction bracket 41. The second auxiliary grippers B12 and the second traction gripper B11 jointly support the raw bamboo so that the raw bamboo remains on the working path of the yellowing mechanism 3; the second auxiliary grippers B12 are also connected to the controller.

[0132] Since the second traction gripper B11 will always lock the raw bamboo during operation, the second auxiliary gripper B12 can be configured to only support the raw bamboo but not lock it, so that the raw bamboo can move relative to the second auxiliary gripper B12, or it can also lock the raw bamboo like the second traction gripper B11. When the second auxiliary gripper B12 only plays a supporting role, the second auxiliary gripper B12 can be fixedly mounted on the traction bracket 41, or it can be slidably mounted in the horizontal slide groove 411 of the traction bracket 41 like the second traction gripper B11; and when the second auxiliary gripper B12 will lock the raw bamboo, in order to allow the raw bamboo to move, the second auxiliary gripper B12 needs to be configured to be slidably mounted in the horizontal slide groove 411 of the traction bracket 41 like the second traction gripper B11.

[0133] like Figure 11 、 Figure 12 and Figure 13 Shown, combined Figure 10 It can be seen that the yellowing removal component B2 of this embodiment includes a rotating rod B21 rotatably connected to the traction bracket 41, and the rotating rod B21 is driven to rotate by a second circumferential driver (not shown in the figure), thereby driving the transverse partition breaking tip B22 and the bamboo yellow grinding airbag B23 provided on the rotating rod B21 to work; the second circumferential driver is also connected to the controller.

[0134] Among them, the transverse septum breaking tip B22 is detachably mounted on the head end of the rotating rod B21, that is, the end facing the original bamboo fixing assembly B1, and is used to break and remove the internode transverse septum of the original bamboo before polishing the bamboo yellow.

[0135] Depend on Figure 12 As can be seen, the septum-breaking tip B22 is conical in shape. This conical septum-breaking tip B22 possesses sufficient breaking force while simultaneously removing as much intersegmental septa as possible, removing obstructions for the bamboo yellow polishing airbag B23 and preventing scratches therefrom. Furthermore, the base radius of the cone is larger than the outer diameter of the rotating rod B21, ensuring that any remaining intersegmental septa do not scratch the outer circumference of the rotating rod B21. Furthermore, the base radius of the cone is smaller than the outer diameter of the bamboo yellow polishing airbag B23, preventing it from affecting its normal operation.

[0136] like Figure 11It can be seen that the bamboo yellow polishing airbag B23 is hollow cylindrical (same as Example 1, the arrangement of the bamboo yellow polishing airbag B23 in this embodiment is also based on the purpose of not forming a polishing gap in the circumferential direction of the rotating rod B21 or the formed polishing gap is not closed in the circumferential direction), and is detachably installed on the outer wall of the rotating rod B21. The bamboo yellow polishing airbag B23 is made of a polymer elastic material such as silica gel, rubber, etc. as the matrix, and silicon carbide sand, aluminum oxide sand, etc. are selected as the surface abrasive. Therefore, it has an initial state without inflation and a polishing state after inflation.

[0137] like Figure 13 、 Figure 14 、 Figure 15 and Figure 16 As shown, an inflation channel B24 is opened in the rotating rod B21, and the inflation channel B24 has an air inlet B25 formed at the tail end of the rotating rod B21 and a plurality of air outlets B26 formed on the peripheral wall of the rotating rod B21, and the air nozzle of the bamboo yellow polishing airbag B23 is detachably sealed and connected to the air outlet B26.

[0138] The present invention hides the inflation channel B24, the air inlet B25 and the air outlet B26 in the interior, tail end and outer peripheral wall of the rotating rod B21, i.e., the inner side of the bamboo yellow polishing airbag B23, to avoid interference with the rotating rod B21 entering the original bamboo and the polishing work of the bamboo yellow polishing airbag B23; and connecting the bamboo yellow polishing airbag B23 with the air outlet B26 on the peripheral wall of the rotating rod B21 not only facilitates inflation, but also can firmly connect the bamboo yellow polishing airbag B23 to the rotating rod B21, thereby improving its working stability.

[0139] The bamboo yellow grinding airbag B23 needs to be inflated to maintain its grinding state. The air inlet B25 can be closed after the inflation is completed, or an inflation component can be used to keep it continuously inflated during the grinding process.

[0140] Obviously, the use of an inflatable component to continuously inflate the bamboo yellow polishing airbag B23 during the polishing process can ensure that the bamboo yellow polishing airbag B23 always remains inflated, ensuring the yellowing efficiency. At this time, the inflatable component may include an inflatable tube (not shown in the figure), one end of which is rotatably connected to the air inlet B25 and sealed, and the other end of the inflatable tube is connected to the air source. Since the inflatable tube needs to maintain a connection with the rotating rod B21 during the rotation of the rotating rod B21, it is necessary to set the inflatable tube to be rotatably connected to the rotating rod B21 so that the rotation of the rotating rod B21 causes the inflatable tube to twist, ensuring that the inflatable tube can maintain its own position unchanged.

[0141] Depend on Figure 15It can be seen that although only one bamboo yellow polishing airbag B23 is provided in this embodiment, a large number of air outlets B26 are provided on the rotating rod B21. Multiple air outlets B26 supply air to the bamboo yellow polishing airbag B23 at the same time, so that it can be quickly inflated and reach a working state; when other smaller bamboo yellow polishing airbags B23 need to be replaced, it can also ensure that each bamboo yellow polishing airbag B23 can have an independent air outlet B26.

[0142] The arrangement of the multiple air outlets B26 on the rotating rod B21 is arbitrary and can be selected by those skilled in the art based on specific needs. In this embodiment, the air outlets B26 include at least one group arranged axially along the rotating rod B21, and each group of air outlets B26 includes at least one air outlet arranged circumferentially around the rotating rod B21. Adjacent groups of air outlets B26 are arranged side by side or staggered.

[0143] The working principle of the bamboo material removal equipment in this embodiment is as follows:

[0144] First, the bamboo green removal device of Example 1 is used to remove the green bamboo. After the green bamboo is completely removed, the first pulling gripper 42 moves back and forth to deliver the head end of the original bamboo from which the green bamboo has been removed to the position of the second pulling gripper B11.

[0145] Before the yellowing operation begins, the second auxiliary gripper B12 and the second traction gripper B11 are both in an open state;

[0146] When the yellowing operation is required, when the raw bamboo passes the second auxiliary gripper B12 and the second traction gripper B11, the controller first controls the second auxiliary gripper B12 and the second traction gripper B11 to hold the raw bamboo tightly; then the second linear drive is activated, and the second linear drive drives the second traction gripper B11 to slide in the direction of the rotating rod B21;

[0147] At the same time, the controller activates the second circumferential drive, which drives the rotating rod B21 to rotate. As the raw bamboo gradually approaches the rotating rod B21, the septum breaking tip B22 at the head end of the rotating rod B21 is first inserted into the raw bamboo. During the rotation process, the internode septa of the raw bamboo are broken one by one.

[0148] The bamboo yellow polishing airbag B23 is in an uninflated state before entering the original bamboo. After the bamboo yellow polishing airbag B23 completely enters the original bamboo, the controller starts the inflation component to inflate the bamboo yellow polishing airbag B23. The inflated bamboo yellow polishing airbag B23 completely fits the internal space of the original bamboo. During the rotation process of the rotating rod B21, the bamboo yellow polishing airbag B23 polishes and removes the bamboo yellow inside the original bamboo.

[0149] In order to ensure the grinding efficiency, the second linear drive can also drive the second traction gripper B11 to move back and forth in a short distance, so that the bamboo yellow grinding airbag B23 can perform reciprocating grinding to remove the bamboo yellow and the remaining bamboo node partitions;

[0150] After polishing is completed, the controller controls the second linear drive to bring the second traction gripper B11 back to its original position, and at the same time controls the second traction gripper B11 and each second auxiliary gripper B12 to open, and places the bamboo material that has completed bamboo yellow polishing on the finished product conveyor belt B3 below (guardrails B4 are provided on the opposite sides of the finished product conveyor belt B3) and transports it downstream; and controls the inflation component to stop inflating and deflate the gas inside the bamboo yellow polishing airbag B23, waiting for the next polishing.
