Description

Technical Field

[0001] This invention relates to the field of bamboo shavings preparation technology, and more specifically to a bamboo shavings preparation production line for bamboo oriented strand board. Background Technology

[0002] The following literature is available for reference regarding bamboo oriented strand board:

[0003] The 2006 publication CN1851200A describes a building template using oriented strand board (OSB) as the substrate and its manufacturing method, which solves the problem of efficient utilization of small-diameter materials.

[0004] In November 2007, publication number 101066603A disclosed a method for manufacturing bamboo oriented strand board (OSB), which described the steps for processing bamboo into OSB particleboard.

[0005] In January 2011, the Journal of Agricultural Machinery published an article titled "Design and Experiment of Bamboo OSB Slicing Machine" by Fu Wansi, Shen Yi, and Zhou Jianbo. The article describes a method for producing bamboo shavings for oriented strand board (OSB) from moso bamboo. The process involves first splitting round bamboo into strips, then combining these strips and using a ring cutter to produce shavings. This method is inefficient. Moso bamboo is characterized by its large head and middle sections and small tail sections, along with its smooth surface, leading to significant slippage and vibration during production.

[0006] The preparation of bamboo oriented strand board involves first splitting the whole bamboo into bamboo strips, then collecting the bamboo strips and sending them to a shaving machine to process them into shavings. After drying, gluing, and oriented laying, the shavings are arranged in a crisscross pattern according to a specified direction, and then hot-pressed into a type of engineered wood.

[0007] The outer surface of bamboo, known as the bamboo green layer, mainly consists of a waxy layer, a silicone layer, and the densest part of the vascular bundles. This densest part, with its high vascular bundle content and density, experiences significant growth stress, making it difficult to stretch or compress, and thus resistant to deformation. Consequently, the bamboo green layer is hard and has a smooth surface. In the production of bamboo oriented strand board (OSB), selecting bamboo green strips presents a challenge, as conventional methods cannot glue and press the bamboo green layer together, necessitating its removal. During production, bamboo shavings with bamboo green strips retained at the edges are considered acceptable; however, if most of the length and width of a bamboo shaving is bamboo green, it is called a bamboo green strip and is unsuitable for OSB production. After bamboo chips pass through a shaving machine, bamboo shavings are obtained, containing a mixture of acceptable bamboo shavings and bamboo green strips, making the selection of acceptable bamboo shavings difficult.

[0008] Therefore, how to screen out qualified bamboo shavings and bamboo strips after bamboo shavings are prepared, so that the bamboo shavings meet the production requirements of bamboo oriented strand board and improve production efficiency, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to provide a bamboo shavings preparation production line for bamboo oriented strand board (BST). After preparing bamboo shavings, qualified bamboo shavings and bamboo strips are screened out so that the bamboo shavings meet the production requirements of BST and improve production efficiency.

[0010] This invention is implemented as follows: a bamboo shavings preparation production line for bamboo oriented strand board, characterized in that it includes:

[0011] The feeding and conveying device includes a feeding roller conveyor, a feeding left pressure roller assembly, a feeding right pressure roller assembly, and a height limiting baffle. The feeding left pressure roller assembly and the feeding right pressure roller assembly are respectively located on the left and right sides of the feeding roller conveyor. The height limiting baffle is fixedly installed above the feeding roller conveyor. The feeding roller conveyor is used to place stacked bamboo strips.

[0012] A transition pressure clamping device includes a transition roller conveyor and a transition pressure clamping assembly. The inlet of the transition roller conveyor is connected to the outlet of the feeding conveyor. The transition pressure clamping assembly is disposed on the transition roller conveyor and is used to clamp the stacked bamboo strips.

[0013] A rotary slicing and slicing machine is installed at the discharge port of the transition roller conveyor. The rotary slicing and slicing machine includes a blade ring and a blade disc. The outer ring of the blade ring and blade disc is provided with a cutting blade assembly and a slicing blade assembly for radially slicing the stacked bamboo strips.

[0014] A bamboo shaving conveyor is located below the bamboo shaving outlet of the rotary shaving machine;

[0015] A bamboo shavings screening machine is located below the discharge port of the bamboo shavings conveyor.

[0016] A bamboo strip flotation device includes an oil flotation tank, a flotation washing drum, a first scraper conveyor, a first bamboo shavings collection belt conveyor, and an ultrasonic generator tunnel chamber. The inlet of the oil flotation tank is aligned with the outlet of the bamboo shavings screening machine. The flotation washing drum is rotatably connected to the oil flotation tank and is located below the inlet of the oil flotation tank. The first bamboo shavings collection belt conveyor is located at the bamboo shavings outlet of the oil flotation washing tank. The ultrasonic generator tunnel chamber is located in the middle of the first bamboo shavings collection belt conveyor. The first scraper conveyor is located between the flotation washing drum and the inlet of the first bamboo shavings collection belt conveyor.

[0017] The boiling device includes a hot water tank, a bamboo shaving pressing drum, a second scraper conveyor, and a second bamboo shaving collecting mesh belt conveyor. The inlet of the hot water tank is aligned with the outlet of the first bamboo shaving collecting mesh belt conveyor. The bamboo shaving pressing drum is rotatably connected to the hot water tank and is located below the inlet of the hot water tank. The second bamboo shaving collecting mesh belt conveyor is located at the bamboo shaving outlet of the hot water tank. The second scraper conveyor is located between the bamboo shaving pressing drum and the inlet of the second bamboo shaving collecting mesh belt conveyor.

[0018] The inlet of the cooking and carbonization chamber is aligned with the outlet of the second bamboo shavings collecting mesh belt conveyor.

[0019] The bamboo shavings drying kiln has its inlet aligned with the outlet of the cooking and carbonization chamber.

[0020] Also includes: bamboo material preparation and stacking equipment, including:

[0021] In addition to the inner section bamboo splitting machine, bamboo strip combination transport device, and bamboo strip stacker;

[0022] The bamboo stacker is located at the inlet of the feeding and transporting device.

[0023] The advantages of this invention are: 1. Continuous and automated production line operation: A transitional heavy-pressure clamping device clamps and feeds stacked bamboo strips, and a rotary slicing machine cuts the stacked bamboo strips radially with a ring cutter into bamboo shavings. The prepared bamboo shavings are then screened in a bamboo strip flotation device to separate qualified bamboo shavings from bamboo strips. The qualified bamboo shavings are then subjected to ultrasonic cavitation, boiling, steaming, and drying treatments to meet the production requirements of bamboo oriented strand board, resulting in high production efficiency. 2. The rotating flotation washing drum disperses the bamboo shavings entering the oil flotation tank, allowing them to fully enter the oil and facilitating the separation of qualified bamboo shavings from bamboo strips. 3. The bamboo strip flotation device can also collect and discharge the bamboo strips, facilitating their recycling. 4. The bamboo strip barrier effectively prevents the bamboo strip belt from falling into the gap between the oil flotation tank and the bamboo strip collection belt conveyor, preventing bamboo strip sedimentation and equipment malfunction. 5. The protective clamps for the bamboo shaving stacks prevent excessive vibration during shaving, which could affect the shaving quality, and prevent bamboo scraps from flying into the air and causing unnecessary safety issues. 6. During the bamboo shaving process, substandard bamboo waste enters the bamboo waste collection bin, reducing the screening pressure on the bamboo shavings screening machine and the bamboo strip flotation device, thus improving the quality of the bamboo shavings. 7. The ultrasonic generator tunnel bin is located in the middle of the first bamboo shavings collection conveyor belt after the bamboo strip flotation device. When the bamboo shavings pass through the ultrasonic generator tunnel bin, the ultrasonic waves enlarge the pores of the bamboo shavings and remove starch from the bamboo cells during transport. The shavings are then sent to the boiling device for boiling, significantly improving the boiling efficiency of the bamboo shavings. Attached Figure Description

Detailed Implementation

[0061] This invention provides a bamboo shavings preparation production line for bamboo oriented strand board (BST) by providing a production line that solves the shortcomings of low production efficiency and difficulty in screening qualified bamboo shavings in the prior art. It enables the screening of qualified bamboo shavings and bamboo strips after bamboo shavings preparation, so that the bamboo shavings meet the production requirements of BST and improves production efficiency.

[0062] The technical solution in this invention aims to overcome the above-mentioned shortcomings, and the overall approach is as follows:

[0063] Bamboo materials such as moso bamboo and raw bamboo are first cut into bamboo strips on bamboo material preparation and stacking equipment, and then the bamboo strips are stacked into a stack shape on a bamboo strip stacking machine. Stacked bamboo strips are fed from a bamboo strip stacker into a feeding and conveying device, and then from the feeding and conveying device into a transitional heavy-pressure clamping device. The transitional heavy-pressure clamping device clamps the stacked bamboo strips, and a rotary shaving machine performs radial cutting along the bamboo, shaving the stacked bamboo strips into bamboo shavings. The prepared bamboo shavings are screened in a bamboo green skin strip flotation device to separate qualified bamboo shavings and bamboo green skin strips. Qualified bamboo shavings are first subjected to ultrasonic cavitation treatment. Under the action of ultrasound, the pores of the bamboo shavings are enlarged and the starch inside the bamboo cells is removed. Then, they enter a water boiling device to remove oil and dissolve some of the starch inside and outside the bamboo cells with hot water, while increasing the moisture content of the bamboo. Then, they enter a steaming and carbonization chamber to dissolve more of the starch inside the bamboo cells. Finally, they enter a bamboo shaving drying kiln for drying, so that the bamboo shavings meet the production requirements of bamboo oriented strand board, with a high degree of automation.

[0064] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0065] See Figures 1 to 26 The preferred embodiment of the present invention.

[0066] A bamboo shavings preparation production line for bamboo oriented strand board includes:

[0067] The feeding and conveying device 1 is used to receive and transport stacked bamboo strips 30, which come from the bamboo strip stacker 403 of the bamboo material preparation and stacking equipment; the stacked bamboo strips 30 are as follows: Figure 5 and Figure 15 As shown, the bamboo strips are stacked layer by layer with the green side facing upwards. Bamboo has a structure where one end is larger and the other end is smaller. After bamboo 304 is cut into bamboo strips 303, bamboo strips 303 also have a large end 3032 and a small end 3033. Each layer of bamboo strips is stacked alternately facing each other, that is, the bamboo strips of one layer are placed with the large end on the left, and the bamboo strips of the next layer are placed with the large end on the right, which helps to stabilize the bamboo strip stacking structure.

[0068] The feeding and conveying device 1 includes a feeding roller conveyor 11, a left feeding pressure roller assembly 12, a right feeding pressure roller assembly 13, and a height limiting baffle 14. The left feeding pressure roller assembly 12 and the right feeding pressure roller assembly 13 are located on the left and right sides of the feeding roller conveyor 11, respectively. The height limiting baffle 14 is fixedly installed above the feeding roller conveyor 11. The feeding roller conveyor 11 is used to place the stacked bamboo strips 30. The left feeding pressure roller assembly 12 and the right feeding pressure roller assembly 13 serve as guides to prevent the stacked bamboo strips 30 from deviating from their position during transportation. The height limiting baffle 14 limits the feeding height of the stacked bamboo strips 30 to prevent them from being too high to fit into the subsequent transition pressure clamping device 2. The bamboo strip stacker 403 of the bamboo material preparation and stacking equipment feeds the stacked bamboo strips 30 into the feeding roller conveyor 11.

[0069] The transition pressure clamping device 2 includes a transition roller conveyor 21 and a transition pressure clamping assembly 22. The inlet of the transition roller conveyor 21 is connected to the outlet of the feeding conveyor 1. The transition pressure clamping assembly 22 is installed on the transition roller conveyor 21 and is used to clamp the stacked bamboo strips 30. When it is necessary to transport the stacked bamboo strips 30 to the rotary slicing machine 3, the transition pressure clamping assembly 22 releases the stacked bamboo strips 30. When the stacked bamboo strips 30 protrude from the outlet of the transition roller conveyor 21 to a specified length, the transition pressure clamping assembly 22 clamps the stacked bamboo strips 30, and then the rotary slicing machine 3 slices the stacked bamboo strips 30.

[0070] A rotary shaving machine 3 is installed at the discharge port of the transition roller conveyor 21. The rotary shaving machine 3 includes a blade ring disc 31. The outer ring of the blade ring disc 31 is provided with a cutting blade assembly 32 and a cutting blade assembly 33 for radially shaving the stacked bamboo strips 30. The cutting blade assembly 32 cuts out sheet-like bamboo shavings from the stacked bamboo strips 30. The cutting blade assembly 33 is a ring blade structure that cuts the bamboo strips exposed at the discharge port of the transition roller conveyor 21 as the blade ring disc 31 moves.

[0071] A bamboo shaving conveyor 6 is positioned below the bamboo shaving outlet of the rotary shaving machine 3. The bamboo shaving conveyor 6 can be a belt conveyor, transporting the bamboo shavings to a bamboo shaving screening machine 7 for screening. It also includes a bamboo shaving guide bin 38, positioned between the bamboo shaving outlet of the rotary shaving machine 3 and the bamboo shaving conveyor 6. The bamboo shaving guide bin 38 facilitates the collection of bamboo shavings, which fall along the guide bin 38 into the bamboo shaving conveyor 6.

[0072] A bamboo shaving screening machine 7 is located below the discharge port of the bamboo shaving conveyor 6. The bamboo shaving screening machine 7 can be one or a combination of vibrating screens, disc screens, and mesh screens. The screening machine removes dust and granular bamboo chips from the bamboo shaving material. The bamboo shavings then enter the bamboo strip flotation device 8 and the oil flotation tank 81.

[0073] When bamboo shavings are rotary-cut along their radial direction, each shaving produces two strips of bamboo green skin 301, namely, the bamboo green skin strips 301 obtained from the first and last cuts. If the bamboo shavings are irregularly arranged, more bamboo green skin strips 301 will be produced during the cutting process. Bamboo green skin 3031 mainly consists of a waxy layer, a silicone layer, and the densest part of the vascular bundles. The densest part of the vascular bundles means that the vascular bundles have a high content, high density, and high growth stress, making them difficult to stretch and compress, and thus difficult to deform. Therefore, bamboo green skin has high hardness and a smooth surface, making it impossible to apply adhesive and press it in by conventional methods, so it needs to be removed. If the thickness edge of a bamboo shaving retains bamboo green skin 3031 or has no bamboo green skin, it does not affect the adhesive pressing and laying of bamboo oriented strand board production, and is considered qualified bamboo shavings 302. If most of the length and width of a bamboo shaving is bamboo green skin, such bamboo shavings are called bamboo green skin strips, and are not suitable for adhesive pressing and laying in bamboo oriented strand board production. The bamboo green strip flotation device 8 separates qualified bamboo shavings 302 from bamboo green strips 301.

[0074] The bamboo shavings flotation device 8 includes an oil flotation tank 81, a flotation washing drum 82, a first scraper conveyor 83, a first bamboo shavings collection belt conveyor 84, and an ultrasonic generator tunnel chamber 841. The inlet of the oil flotation tank 81 is aligned with the outlet of the bamboo shavings screening machine 7. The flotation washing drum 82 is rotatably connected to the oil flotation tank 81 and is located below the inlet of the oil flotation tank 81. The first bamboo shavings collection belt conveyor 84 is located at the bamboo shavings outlet of the oil flotation tank 81, and the ultrasonic generator tunnel chamber 841 is located in the middle of the first bamboo shavings collection belt conveyor 84. The first scraper conveyor 83 is located between the flotation washing drum 82 and the inlet of the first bamboo shavings collection belt conveyor 84.

[0075] The oil in oil flotation tank 81 has a density of 0.8-0.9 g / cm³. 3 This includes vegetable oils, recycled light edible oils, and industrial waste oils such as heat transfer oils. Because the density of bamboo strips is greater than 0.9 g / cm³... 3Therefore, bamboo strips will sink in the oil; qualified bamboo particleboard has a lower density and will therefore float in the oil. The rotating flotation washing drum 82 disperses the bamboo shavings entering the oil flotation tank 81, allowing them to fully enter the oil and facilitating the separation of qualified bamboo shavings 302 from bamboo strips 301. The qualified bamboo shavings 302 floating in the oil are pushed towards the first scraper conveyor 83 by the flotation washing drum 82. Under the push of the scraper 831 (the scraper is a mesh plate) of the first scraper conveyor 83, the qualified bamboo shavings 302 are scraped to the inlet of the first bamboo shavings collecting mesh conveyor 84. The first bamboo shavings collecting mesh conveyor 84 carries the qualified bamboo shavings 302 out of the oil flotation tank 81. The qualified bamboo shavings 302 undergo ultrasonic cavitation treatment in the ultrasonic generator tunnel chamber 841. Under the action of ultrasound, the pores of the bamboo shavings become larger and the starch in the bamboo cells is removed before entering the boiling device 9.

[0076] The boiling device 9 includes a hot water tank 91, a bamboo shaving pressing drum 92, a second scraper conveyor 93, and a second bamboo shaving collecting conveyor belt 94. The inlet of the hot water tank 91 is aligned with the outlet of the first bamboo shaving collecting conveyor belt 94. The bamboo shaving pressing drum 92 is rotatably connected to the hot water tank 91 and is located below the inlet of the hot water tank 91. The second bamboo shaving collecting conveyor belt 94 is located at the bamboo shaving outlet of the hot water tank 91. The second scraper conveyor 93 is located between the inlet of the bamboo shaving pressing drum 92 and the inlet of the second bamboo shaving collecting conveyor belt 94. The main purpose of the boiling device 9 is to remove oil and balance the moisture content, unify the subsequent process parameters, dissolve some of the starch inside and outside the bamboo cells in the hot water, and increase the moisture content of the bamboo so that more starch inside the bamboo cells can be dissolved during steaming and carbonization. The rotating bamboo shavings pressing drum 92 helps to fully introduce the bamboo shavings into the hot water. The bamboo shavings float on the water surface and are pushed towards the second scraper conveyor 93 by the bamboo shavings pressing drum 92. Under the push of the scraper of the second scraper conveyor 93, the bamboo shavings are scraped to the inlet of the second bamboo shavings collecting mesh conveyor 94. The second bamboo shavings collecting mesh conveyor 94 carries the qualified bamboo shavings 302 out of the hot water pool 91 and then into the cooking and carbonization chamber 10.

[0077] The cooking and carbonization chamber 10 has its inlet aligned with the outlet of the second bamboo shavings collecting conveyor belt 94. The cooking and carbonization chamber 10 includes a chamber shell 101 and a feeder 102. Steam nozzles 103 are installed on the side wall of the chamber shell 101 and are connected to a steam pipe 104, which is equipped with a valve (not shown). The feeder 102 is installed at the bottom of the chamber shell 101 and has blades. The steam nozzles 103 spray steam onto the bamboo shavings inside the chamber shell 101. The steam forms hot water droplets on the surface of the bamboo shavings. Under the action of the steam, the pores of the bamboo become larger, and the starch within the bamboo cells dissolves more quickly into the hot water droplets on the bamboo surface. The steam temperature is 80-110℃. The feeder 102 rotates its blades, pushing the bamboo shavings towards the outlet.

[0078] A bamboo shaving drying kiln 20 has its inlet aligned with the outlet of the cooking and carbonization chamber 10. The kiln 20 includes a dehydrating mesh belt conveyor 201, located below the outlet of the cooking and carbonization chamber 10. Bamboo shavings exiting the outlet of the cooking and carbonization chamber 10 first fall onto the dehydrating mesh belt conveyor 201. During transport, the mesh belt of the dehydrating mesh belt conveyor 201 initially filters out the cooking water from the bamboo shavings before transporting them to the drying kiln 20. Finally, the bamboo shavings are dried, resulting in bamboo shavings that meet the requirements for producing bamboo oriented strand board (OSB).

[0079] Furthermore, the bamboo strip flotation device 8 also includes a bamboo strip collecting mesh belt conveyor 85 and a scraper conveyor 86. The bamboo strip collecting mesh belt conveyor 85 is located in the oil flotation tank 81 and below the flotation washing drum 82. The scraper conveyor 86 is located at the bamboo strip outlet of the oil flotation tank 81, and the inlet of the scraper conveyor 86 is aligned with the outlet of the bamboo strip collecting mesh belt conveyor 85.

[0080] The bamboo strip 301 that fell into the oil sank and landed on the bamboo strip collection belt conveyor 85. The bamboo strip collection belt conveyor 85 moved the bamboo strip 301 towards the scraper conveyor 86, which transported the bamboo strip 301 out of the oil flotation tank 81. The bamboo strip flotation device 8 collected and discharged the bamboo strip 301, facilitating its recovery.

[0081] Furthermore, the bamboo strip flotation device 8 also includes a bamboo strip barrier 87, which is fixedly installed in the gap between the bamboo strip collecting conveyor belt 85 and the oil flotation tank 81.

[0082] The bamboo strip barrier 87 effectively prevents the bamboo strip 301 from falling into the gap between the oil flotation tank 81 and the oil flotation tank 81, and prevents the bamboo strip 301 from settling and causing equipment failure.

[0083] Furthermore, the bamboo strip flotation device 8 also includes a heating plate 88, which is fixedly installed inside the oil flotation tank 81.

[0084] Heating plate 88 consumes electrical energy and generates heat to control the oil temperature in oil flotation cell 81.

[0085] Furthermore, the bamboo strip flotation device 8 also includes a first valve 89, and the bottom of the oil flotation tank 81 is provided with a first drain outlet 811, and the first valve 89 is installed at the first drain outlet 811; the water boiling device 9 also includes a second valve 95, and the bottom of the hot water tank 91 is provided with a second drain outlet 911, and the second valve 95 is installed at the second drain outlet 911.

[0086] When it is necessary to drain the oil from the oil flotation tank 81, simply open the first valve 89. The oil flotation tank 81 has an oil inlet 812 at the top for replenishing oil. The oil level line 810 in the oil flotation tank reaches the position of the flotation washing drum 82. When it is necessary to drain the water from the hot water tank 91, simply open the second valve 95. The water level line 96 in the hot water tank 91 is at the position of the bamboo shavings pressing drum 92.

[0087] Furthermore, the transition pressure clamping assembly 22 includes a side pressure roller 221, a side pressure plate 222, an upper pressure roller 223, and an upper pressure plate 224. Several side pressure rollers 221 and side pressure plates 222 are arranged on both sides of the transition roller conveyor 21. The side pressure rollers 221 and side pressure plates 222 can perform synchronous clamping or retracting movements. Several upper pressure rollers 223 and upper pressure plates 224 are arranged above the transition roller conveyor 21. The upper pressure rollers 223 and upper pressure plates 224 can perform synchronous lifting and lowering movements. The side pressure rollers 221 are arranged vertically, and the upper pressure rollers 223 are arranged horizontally. The side pressure rollers 221, upper pressure rollers 223, and the roller rotation speed of the transition roller conveyor 21 are the same.

[0088] The surfaces of the side pressure rollers 221, side pressure plates 222, upper pressure rollers 223, and upper pressure plates 224 are all fixedly fitted with wear-resistant and pressure-resistant rubber. The transition heavy-duty clamping assembly 22 also includes a side pressure bracket, an upper pressure bracket, a side push assembly, and an upper push assembly. Two side pressure brackets are symmetrically arranged on both sides of the transition roller conveyor 21. Each side pressure roller 221 and side pressure plate 222 is symmetrically connected to the two side pressure brackets. A side pressure roller drive motor (not shown) is mounted on each side pressure bracket and is drively connected to the side pressure roller 221. Two side push assemblies are symmetrically arranged on both sides of the transition roller conveyor 21. One side push assembly... The pushing end of the component is fixedly connected to one of the side pressure brackets, driving the side pressure bracket to perform opposing clamping or reversing releasing movements. The upper pressure bracket is located above the transition roller conveyor 21. Each of the upper pressure rollers 223 and the upper pressure plate 224 is connected to the upper pressure bracket. The upper pressure bracket is equipped with an upper pressure roller drive motor (not shown), which is drively connected to the upper pressure roller 223. The pushing end of the upward pushing assembly is fixedly connected to the upper pressure bracket, driving the upper pressure bracket to perform lifting and lowering movements. The side pushing assembly and the upward pushing assembly can be pneumatic cylinders or hydraulic cylinders.

[0089] Furthermore, the rotary slicing and slicing machine 3 also includes a motor 34, a first slide 35, a slicing length sensor 36, and a bamboo support plate 37. The motor 34 is fixedly connected to the first slide 35 and also drives the blade ring and cutter disc 31 to rotate. The first slide 35 slides along the conveying direction perpendicular to the transition roller conveyor 21. The slicing length sensor 36 is used to detect whether the bamboo slices have reached the predetermined slicing length position. The bamboo support plate 37 is located on the opposite side of the blade ring and cutter disc 31. The blade ring and cutter disc 31 has a bamboo shaving channel 311 inside, a bamboo shaving discharge port 312 on one side in the middle, and a pulsator feed ring 313 on the other side in the middle.

[0090] The movement of the first slide 35 is a radial feed motion along the bamboo strip. In this embodiment, the first slide 35 is driven by an existing drive system. The slicing length sensor 36 is a type of limit sensor, distance sensor, infrared sensor, digital sensor, etc. When the slicing length sensor 36 detects that the bamboo strip has reached the predetermined slicing length position, the slicing length sensor 36 sends a signal to the transition pressure clamping device 2, which clamps the stacked bamboo strip 30. Then, the rotary slicing machine 3 starts the blade ring disc 31, and the first slide 35 moves radially along the bamboo strip to begin slicing the bamboo strip. After slicing is completed, the first slide 35 retracts, and the transition pressure clamping device 2 releases the stacked bamboo strip 30. The transition pressure clamping assembly 22 includes side pressure rollers 221, side pressure plates 222, upper pressure rollers 223, and upper pressure plates 224, which perform synchronous reverse release movements. Then, the transition roller conveyor 21, side pressure roller 221, and upper pressure roller 223 operate, driving the stacked bamboo strips 30 to move forward synchronously. The slicing length sensor 36 detects again whether the bamboo strip has reached the predetermined slicing length position. When the slicing length sensor 36 detects that the bamboo strip has reached the predetermined slicing length position, the slicing length sensor 36 sends a signal to the transition heavy pressure clamping device 2, which clamps the stacked bamboo strips 30. Then, the rotary slicing machine 3 starts the blade ring disc 31, and the first slide 35 moves radially along the bamboo strip to begin slicing the bamboo strip; this process is repeated continuously.

[0091] In this embodiment, the bamboo support plate 37 is connected to the existing pushing device 371. For example, a cylinder or hydraulic cylinder can be used to push the bamboo support plate 37, causing it to abut against a stacked bamboo strip 30 (generally 30-300mm long, which can be preset according to the actual length of the shavings) emerging from the transition pressure clamping device 2. This helps the rotary shaving machine 3 to slice the bamboo strips and reduces vibration. During the bamboo shaving process, the bamboo shavings generated by the cutting blade assembly 32 enter the bamboo shaving channel 311 and then reach the bamboo shaving discharge port 312. The impeller feed ring 313 pushes the bamboo shavings out of the bamboo shaving discharge port 312, and through the bamboo shaving guide chamber 38, the bamboo shavings fall onto the bamboo shaving conveyor 6. The structure of the impeller feed ring 313 is similar to that of a washing machine feeder.

[0092] Furthermore, it also includes: a protective clamp 4 for the bamboo chip stack, which is set at the discharge port of the transition roller conveyor 21 and opposite to the rotary slicing machine 3; the protective clamp 4 for the bamboo chip stack includes a second slide 41, a balance frame 42, a bamboo chip stack support plate 43, a bamboo chip stack auxiliary pressure plate 44, a first lifting mechanism 45, and a second lifting mechanism 46. The balance frame 42 is connected to the second slide 41 through the first lifting mechanism 45. The bamboo chip stack support plate 43 is fixedly connected to the balance frame 42. The bamboo chip stack auxiliary pressure plate 44 is connected to the balance frame 42 through the second lifting mechanism 46. The bamboo chip stack auxiliary pressure plate 44 is located above the bamboo chip stack support plate 43. The second slide 41 slides along a direction perpendicular to the conveying direction of the transition roller conveyor 21.

[0093] The bamboo support plate 37 is positioned to the left between the bamboo slice stack support plate 43 and the bamboo slice stack auxiliary pressure plate 44. The bamboo slice stack support plate 43 and the bamboo slice stack auxiliary pressure plate 44 apply a small pressure (less than the clamping force of the transition heavy-duty clamping assembly 22, only serving to hold the stacked bamboo slices 30) to the section of the stacked bamboo slices 30 exposed at the discharge port of the transition roller conveyor 21. The first lifting mechanism 45 and the second lifting mechanism 46 are hydraulic cylinders or pneumatic cylinders, etc.

[0094] The protective clamp 4 for the bamboo slice stack serves to prevent excessive vibration during bamboo slice cutting, which could affect the cutting quality, and to prevent bamboo scraps generated during the cutting process from flying into the air and causing unnecessary safety issues. The second slide 41 of the protective clamp 4 for the bamboo slice stack slides within its own track 47. After the stacked bamboo slices 30 are exposed at the discharge port of the transition roller conveyor 21, the protective clamp 4 for the bamboo slice stack slides to the right. The bamboo slice stack support plate 43 and the bamboo slice stack auxiliary pressure plate 44 are located on the upper and lower sides of the stacked bamboo slices 30, respectively. The first lifting mechanism 45 raises the bamboo slice stack support plate 43, and the second lifting mechanism 46 gently presses down the bamboo slice stack auxiliary pressure plate 44 to hold the stacked bamboo slices 30 to be cut. The protective clamp 4 for slicing bamboo strips is electrically connected to the rotary slicing machine 3. After the protective clamp 4 holds the stacked bamboo strips 30, the rotary slicing machine 3 begins to slice the stacked bamboo strips 30. During slicing, the distance between the outer ring of the blade ring 31 and the bamboo strip stack support plate 43 and auxiliary pressure plate 44 of the protective clamp 4 is always maintained at five millimeters.

[0095] Furthermore, it also includes: a bamboo waste collection bin 5, located below the cutter ring 31; and a bamboo waste conveyor 51, located below the discharge port of the bamboo waste collection bin 5.

[0096] The bamboo waste collection bin 5 is located between the discharge port (below) of the transition roller conveyor 21 and the bamboo shaving conveyor 6. Bamboo scraps, incompletely shaved bamboo shavings, and unshaved bamboo pieces (the last portion of the stacked bamboo pieces 30 clamped by the transition pressure clamping assembly 22) generated during the bamboo cutting process by the cutting blade assembly 32 and cutting blade assembly 33 of the blade ring disc 31 all fall into the lower bamboo waste collection bin 5. The bamboo waste conveyor 51 transports the bamboo scraps, incompletely shaved bamboo shavings, and unshaved bamboo pieces from the bamboo waste collection bin 5. The bamboo waste conveyor 51 can be a belt conveyor.

[0097] Furthermore, it also includes: bamboo material preparation and stacking equipment 40, comprising:

[0098] The bamboo splitting machine 401 is used to split the whole bamboo 304 into multiple bamboo pieces 303 and remove the inner nodes 305 of the bamboo.

[0099] The bamboo strip combined transport device 402 includes a constant speed belt conveyor 4021, an accelerated belt conveyor 4022, a bamboo strip gathering belt conveyor 4023, a telescopic belt conveyor 4024, a bamboo strip height limit plate 4025, a first limit rod 4026, a first lifting control component, a second limit rod 4027, a second lifting control component, a third limit rod 4028, a third lifting control component, and a bamboo strip fullness sensor 4029. The constant speed belt conveyor 4021, the accelerated belt conveyor 4022, the bamboo strip gathering belt conveyor 4023, and the telescopic belt conveyor 4024 are connected end to end in sequence. The inlet of the constant speed belt conveyor 4021 is used to receive the bamboo strips 303 produced by the bamboo splitting machine 401 (excluding inner nodes).

[0100] The first limiting rod 4026 is disposed in the contact area between the constant speed belt conveyor 4021 and the accelerating belt conveyor 4022. The lifting end of the first lifting control component is fixedly connected to the first limiting rod 4026. The second limiting rod 4027 is disposed in the side area of ​​the accelerating belt conveyor 4022. The lifting end of the second lifting control component is fixedly connected to the second limiting rod 4027. The third limiting rod 4028 is disposed in the contact area between the bamboo strip gathering belt conveyor 4023 and the telescopic belt conveyor 4024. The lifting end of the third lifting control component is fixedly connected to the third limiting rod 4028.

[0101] The bamboo strip filling sensor 4029 is installed at the entrance of the bamboo strip collection belt conveyor 4023 and is also electrically connected to the first lifting control component, the second lifting control component, and the third lifting control component.

[0102] The bamboo strip height limit plate 4025 is fixedly installed above the bamboo strip collection belt conveyor 4023, and is also located between the bamboo strip filling sensor 4029 and the third limit rod 4028.

[0103] The bamboo strip stacking machine 403 includes a lifting platform 4031, a stacking roller conveyor 4032, a left stacking pressure roller assembly 4033, and a right stacking pressure roller assembly 4034. The stacking roller conveyor 4032 is fixedly installed on the lifting platform 4031. The left stacking pressure roller assembly 4033 and the right stacking pressure roller assembly 4034 are located on the left and right sides of the lifting platform 4031, respectively, and can move left and right.

[0104] The outlet of the telescopic belt conveyor 4024 can move left and right above the stacking roller conveyor 4032 to stack bamboo strips 304 on the stacking roller conveyor 4032.

[0105] The bamboo stacker 403 is located at the inlet of the feeding and conveying device 1.

[0106] After the entire bamboo stalk 304 passes through the inner node-removing bamboo splitting machine 401, the resulting bamboo strips 303 enter the inlet of the constant-speed belt conveyor 4021 of the bamboo strip assembly and transport device 402. The bamboo strips sequentially pass through the accelerating belt conveyor 4022, the bamboo strip gathering belt conveyor 4023, and the telescopic belt conveyor 4024, and are finally laid on the bamboo strip stacker 403. The accelerating belt conveyor 4022 moves at a higher speed than the constant-speed belt conveyor 4021. In this embodiment, the first lifting control component, the second lifting control component, and the third lifting control component mainly consist of cylinders or hydraulic cylinders and solenoid valves.

[0107] When the first limit rod 4026, the second limit rod 4027, or the third limit rod 4028 rises, the limit rods prevent the bamboo strips from moving forward. The bamboo strip filling sensor 4029 is an existing photoelectric sensor, position sensor, etc. When there are no bamboo strips in the detection area of ​​the bamboo strip filling sensor 4029, the first lifting control component causes the first limit rod 4026 to periodically move up and down, transferring the bamboo strips from the constant speed belt conveyor 4021 to the accelerated belt conveyor 4022 at intervals. The second lifting control component lowers the second limit rod 4027, and the third lifting control component raises the third limit rod 4028. The accelerated belt conveyor 4022 causes the bamboo strips to move rapidly towards the bamboo strip gathering belt conveyor 4023. Because the third limit rod 4028 blocks the bamboo strips, the bamboo strips are arranged and gathered in the bamboo strip gathering belt conveyor 4023, forming a bamboo strip layer. When the bamboo strip filling sensor 4029... When bamboo strips are present in the detection area, the width of the assembled bamboo strip layer in the bamboo strip gathering conveyor 4023 is equal to the width of the stacking roller conveyor 4032 of the bamboo strip stacker 403. The second lifting control component raises the second limit rod 4027 to prevent bamboo strips from entering the bamboo strip gathering conveyor 4023. The first lifting control component keeps the first limit rod 4026 in an elevated state to prevent bamboo strips from the constant speed conveyor 4021 from entering the accelerating conveyor 4022. The third lifting control component lowers the third limit rod 4028, and the bamboo strip gathering conveyor 4023 transports the assembled bamboo strip layer to the telescopic conveyor 4024. The channel formed between the bamboo strip height limit plate 4025 and the bamboo strip gathering conveyor 4023 can only accommodate one bamboo strip at a time to ensure that the assembled bamboo strip layer is a single layer.

[0108] The lifting platform 4031 changes the height of the stacking roller conveyor 4032. Initially, the stacking roller conveyor 4032 is at a preset top position. After the telescopic belt conveyor 4024 lays a layer of bamboo strips onto the stacking roller conveyor 4032, the lifting platform 4031 lowers by the height of one layer of bamboo strips. Then, the telescopic belt conveyor 4024 continues to lay the next layer of bamboo strips, forming a layer-by-layer stacking. Thus, the bamboo strips are automatically stacked into a pile shape on the stacking roller conveyor 4032. The telescopic belt conveyor is a piece of existing technology; it can freely extend and retract in the length direction, and the length of the conveyor can be controlled at any time. During the bamboo strip stacking process, the stacking roller conveyor 4032 is in a stopped state. When the outlet of the telescopic belt conveyor 4024 moves to the upper right of the stacking roller conveyor 4032, the neatly arranged bamboo strips reach the outlet of the telescopic belt conveyor 4024. Then, as the neatly arranged bamboo strips fall onto the stacking roller conveyor 4032, the outlet of the telescopic belt conveyor 4024 moves to the left. In this way, the bamboo strips fall onto the stacking roller conveyor 4032 in an orderly manner from right to left, thus laying a layer of bamboo strips.

[0109] When the lifting platform 4031 reaches the preset bottom position, the third limit rod 4028 rises, the bamboo strip collection belt conveyor 4023 stops and transports the arranged bamboo strips to the telescopic belt conveyor 4024; the pressure rollers of the left stacking pressure roller assembly 4033 and the right stacking pressure roller assembly 4034 move closer to the middle and abut against the stacked bamboo strips 30, the stacking roller conveyor 4032 starts and transports the stacked bamboo strips out. The left stacking pressure roller assembly 4033 and the right stacking pressure roller assembly 4034 prevent the stacked bamboo strips from shaking or tilting and stably transport the stacked bamboo strips 30 out. The stacked bamboo strips 30 are transported to the feeding roller conveyor 11 of the feeding and conveying device 1, and then processed into bamboo shavings by the transition heavy pressure clamping device 2 and the rotary cutting and shaving machine 3. The bamboo shavings are then screened, the bamboo green strips are removed, ultrasonic cavitation is performed, water is boiled, steamed and dried, and finally used to prepare bamboo oriented structure particleboard.

[0110] There are two bamboo splitting machines 401, arranged facing each other from left to right. There are also two bamboo strip transport devices 402, arranged parallel to each other vertically. The bamboo strips produced by the two splitting machines 401 enter the two transport devices 402 respectively, and the bamboo strips on the two transport devices 402 are arranged in opposite directions. The bamboo 304 has a structure where one end is larger than the other. Utilizing this characteristic, the split bamboo strips 303 are stacked alternately facing each other; that is, the bamboo strips in one layer have their larger ends 3032 placed on the left, and the bamboo strips in the next layer have their larger ends 3032 placed on the right. This solves the problem of unstable bamboo strip stacking. In this embodiment, the bamboo strips produced by the bamboo splitting machine 401 (excluding inner nodes) on the left have the larger end 3032 on the right and the smaller end 3033 on the left. These bamboo strips then enter the bamboo strip assembly transport device 402 located above. Similarly, the bamboo strips produced by the bamboo splitting machine 401 (excluding inner nodes) on the right have the larger end 3032 on the left and the smaller end 3033 on the right. These bamboo strips then enter the bamboo strip assembly transport device 402 located below. These two bamboo strip assembly transport devices 402 alternately lay the neatly arranged bamboo strip layers onto the stacking roller conveyor 4032 of the bamboo strip stacker 403.

[0111] The bamboo material preparation and stacking equipment 40 also includes a bamboo strip turning device 40210. During the stacking process, it is best to place the bamboo strips with the green surface facing up and the yellow surface facing down. Since the bamboo strips are randomly placed when they fall from the inner section splitting machine 401 into the inlet of the constant-speed belt conveyor 4021 of the bamboo strip combination transport device 402, some bamboo strips are placed with the green surface facing up and the yellow surface facing down, while others are placed with the green surface facing down and the yellow surface facing up. Therefore, it is necessary to turn the bamboo strips that are placed with the green surface facing down and the yellow surface facing up so that they are placed with the green surface facing up and the yellow surface facing down.

[0112] The bamboo strip flipping device 40210 includes a flipping arm 40211, a flipping shaft 40212, a flipping drive assembly, and a bamboo strip color video monitor 40213. The flipping arm 40211 is fixedly connected to the flipping shaft 40212, and the flipping shaft 40212 is rotatably connected to the accelerator belt conveyor 4022. The rotating end of the flipping drive assembly is fixedly connected to the flipping shaft 40212. The flipping arm 40211 is located in the side area of ​​the accelerator belt conveyor 4022 and is also located between the first limit rod 402626 and the second limit rod 4027. The bamboo strip color video monitor 40213 is fixedly installed above the accelerator belt conveyor 4022 and is also electrically connected to the flipping drive assembly and the second lifting control assembly. In this embodiment, the flipping drive assembly is a rotary motor. The bamboo strip color video monitor 40213 captures images of the accelerated belt conveyor 4022. When it detects that the bamboo strips on the accelerated belt conveyor 4022 are yellowish-brown (i.e., the green side is facing down and the yellow side is facing up), the second lifting control component raises the second limit rod 4027 to block the bamboo strips. At this time, the bamboo strips are in the position of the flipping arm 40211. The flipping drive component causes the flipping shaft 40212 to rotate, driving the flipping arm 40211 to flip the bamboo strips backward. When the bamboo strip color video monitor 40213 detects that the bamboo strips are greenish-brown (i.e., the green side is facing up and the yellow side is facing down), the second lifting control component lowers the second limit rod 4027. The flipping arm 40211 does not flip, and the bamboo strips are transported to the bamboo strip collection belt conveyor 4023.

[0113] The bamboo strip color video monitor 40213 is also electrically connected to the first lifting control component. When the bamboo strip color video monitor 40213 detects that the bamboo strip is yellowish-brown, the first lifting control component keeps the first limit rod 402626 in an elevated state, which prevents the bamboo strips from the normal speed belt conveyor 4021 from entering the speed belt conveyor 4022 when the bamboo strips are flipped. When the bamboo strip color video monitor 40213 detects that the bamboo strip is greenish-brown, the bamboo strip color video monitor 40213 starts timing. After the bamboo strip passes the second limit rod 4027 and reaches the bamboo strip collection belt conveyor 4023, that is, after a preset time, the bamboo strip color video monitor 40213 sends a signal to make the first lifting control component return to the state where the first limit rod 402626 periodically moves up and down.

[0114] The bamboo splitting machine 401, excluding the inner section splitting machine, can also use the specific structures described in the embodiments of the present invention. The bamboo splitting machine 401 includes a whole bamboo clamping and conveying device 4011, a bamboo splitting device 4012, and a bamboo strip guiding and inner node removal device 4013. The whole bamboo clamping and conveying device 4011 includes an aerial support 40111, a ground support 40110, an upper roller conveyor 40112, and a lower roller conveyor 40113. The upper roller conveyor 40112 is located on the aerial support 40111, and the lower roller conveyor 40113 is located on the ground support 40110. The space between the upper roller conveyor 40112 and the lower roller conveyor 40113 is a clamping space. After the bamboo 304 enters the clamping space, it is clamped by the upper roller conveyor 40112 and the lower roller conveyor 40113. The upper roller conveyor 40112 and the lower roller conveyor 40113 start simultaneously to send the bamboo to the bamboo splitting device 4012.

[0115] The whole bamboo clamping and conveying device 4011 further includes a first upper telescopic control assembly 40114, a second upper telescopic control assembly 40115, a first lower telescopic control assembly 40116, a second lower telescopic control assembly 40117, and a whole bamboo outer diameter detector 40118; one end of the first upper telescopic control assembly 40114 is hinged to the overhead support 40111, and the other end is hinged to the tail end of the upper roller conveyor 40112; one end of the second upper telescopic control assembly 40115 is fixedly connected to the overhead support 40111, and the other end is fixedly connected to the tail end of the upper roller conveyor 40112. The head end of the upper roller conveyor 40112 is hinged; one end of the first lower telescopic control assembly 40116 is hinged to the ground support 40110, and the other end is hinged to the tail end of the lower roller conveyor 40113; one end of the second lower telescopic control assembly 40117 is fixedly connected to the ground support 40110, and the other end is hinged to the head end of the lower roller conveyor 40113; the whole bamboo outer diameter detector 40118 is fixedly installed at the outlet of the whole bamboo clamping device 4011, and is also electrically connected to the first lower telescopic control assembly 40116.

[0116] The whole bamboo outer diameter detector 40118 detects that during the process of the whole bamboo being sent to the bamboo splitting device 4012, the outer diameter of the whole bamboo changes, that is, the larger end of the bamboo 304 enters the bamboo splitting device 4012 first, and the smaller end enters the bamboo splitting device 4012 later. The whole bamboo outer diameter detector 40118 can be equipped with a video monitor. During the process of the whole bamboo clamping device 4011 transporting the bamboo to the bamboo splitting device 4012, under the control of the whole bamboo outer diameter detector 40118, the first lower telescopic control component 40116 gradually extends, so that the tail end of the lower roller conveyor 40113 gradually rises, so that the center line of the bamboo coincides with the center line of the bamboo splitting blade 40122 during splitting, improving the uniformity of splitting. In this embodiment, the upper telescopic control component and the lower telescopic control component are mainly composed of cylinders or hydraulic cylinders and solenoid valves.

[0117] The bamboo splitting device 4012 includes a bamboo splitting disc 40121 and a bamboo splitting knife 40122. The bamboo splitting knife 40122 is fixedly connected to the bamboo splitting disc 40121. The bamboo splitting disc 40121 is fixedly installed at the outlet of the whole bamboo clamping device 4011. Under the drive of the whole bamboo clamping device 4011, the whole bamboo 304 passes through the bamboo splitting knife 40122 and is split into multiple bamboo pieces 303.

[0118] The bamboo strip guiding and inner node removal device 4013 includes a bamboo strip guiding bracket 40131, an inner node removal cutter 40132 (40133), and a bamboo strip positioning and transport assembly 40134. The bamboo strip guiding bracket 40131 has a bamboo strip guiding cavity 401311, the entrance of which is aligned with the bamboo splitting blade disc 40121. The bamboo strip positioning and transport assembly 40134 includes a first positioning frame 401341, a first positioning roller 401342, a second positioning frame 401343, a second positioning roller 401344, and a compression spring 401345. The first positioning frame 4013... 41 is fixedly connected to the outer side of the bamboo strip guide cavity 401311. The first positioning roller 401342 is rotatably connected to the first positioning frame 401341. The second positioning frame 401343 is connected to the inner side of the bamboo strip guide cavity 401311 through the compression spring 401345. The second positioning roller 401344 is rotatably connected to the second positioning frame 401343. The inner section cutter 40132 (40133) is fixedly connected to the bamboo strip guide cavity 401311 and is also located between the bamboo strip positioning and transport assembly 40134 and the bamboo splitting blade disc 40121. The number of bamboo strip guide cavities 401311 is consistent with the number of bamboo strips being cut. The bamboo strip guide cavities 401311 are structures that expand uniformly outward. After the bamboo strip 303 enters the bamboo strip guide cavity 401311, the bamboo strip 303 spreads outward. After encountering the inner section removal cutter 40132 (40133), the inner section removal cutter removes the inner section 305 of the bamboo strip. The bamboo strip 303 enters between the first positioning roller 401342 and the second positioning roller 401344 of the bamboo strip positioning and transport assembly 40134. The compression spring 401345 is compressed and deformed, causing the second positioning roller 401344 to abut against the bamboo strip, effectively preventing the bamboo strip from shifting when it moves in the bamboo strip guide cavity 401311.

[0119] Figure 18 In the middle, A to D correspond to the entrances and exits of the six bamboo-strip guide cavities, respectively.

[0120] The bamboo strip guide device 4013 further includes a guide wheel 40135, which is rotatably connected to the bamboo strip guide cavity 401311. The guide wheel 40135 helps the bamboo strip enter the bamboo strip positioning and transport assembly 40134 and also effectively reduces the bending of the bamboo strip when it leaves the bamboo strip guide cavity 401311.

[0121] The bamboo-splitting blade 40122 consists of six blades arranged in a ring at even intervals, and the bamboo strip guide cavity 401311 also consists of six blades arranged in a ring at even intervals. In this way, the entire bamboo can be split into six bamboo strips in one go.

[0122] The inner section removal tools are divided into first inner section removal tools 40132 and second inner section removal tools 40133. Six first inner section removal tools 40132 are arranged in a ring with uniform intervals, forming a ring array of blade tips with a diameter of 8cm. Six second inner section removal tools 40133 are arranged in a ring with uniform intervals, forming a ring array of blade tips with a diameter of 25-17cm. During the movement of the bamboo strip, a portion of the inner section of the bamboo is first removed by the first inner section removal tools 40132, and then the remaining inner section of the bamboo is removed by the second inner section removal tools 40133.

[0123] The bamboo splitting machine 401 also includes a valve 4014 and a nozzle 40141. The inlet of the valve 4014 is connected to a compressed air pipe, and the outlet of the valve 4014 is connected to the nozzle 40141. The bamboo strip guide bracket 40131 has a bamboo inner section storage space at the position of the inner section splitting blade, and the nozzle 40141 is aligned with the bamboo inner section storage space. The removed bamboo inner sections fall into the bamboo inner section storage space. When the bamboo inner section storage space is full, and during the interval when no bamboo splitting is being performed, the valve 4014 is opened, and compressed air is sprayed from the nozzle 40141 into the bamboo inner section storage space, thereby discharging the removed bamboo inner sections and freeing up space. The position of the first inner section splitting blade 40132 corresponds to the first bamboo inner section storage space 401312, and the position of the second inner section splitting blade 40133 corresponds to the second bamboo inner section storage space 401313.

[0124] The bamboo splitting machine 401, excluding the inner section splitting machine, also includes bamboo strip auxiliary transport robots 4015 and guide rails 4016. Multiple bamboo strip auxiliary transport robots 4015 are slidably connected to the guide rails 4016, with the grippers of the robots 4015 aligned with the outlet of the bamboo strip guide cavity 401311. There are six bamboo strip auxiliary transport robots 4015. Bamboo strips 303 exiting the bamboo strip guide cavity 401311 pass sequentially through the grippers of the six robots 4015, preventing the bamboo strips from scattering. At this time, the bamboo strips are suspended. When the grippers of the robots 4015 open, the bamboo strips fall relatively stably into the inlet of the constant-speed belt conveyor 4021, effectively reducing the degree of bamboo strip scattering.

[0125] The bamboo stacker 403 also includes a water atomizing nozzle 4035, which is positioned towards the roller conveyor. The function of the water atomizing nozzle 4035 is to spray a layer of water film onto the bamboo green and bamboo yellow surfaces, increasing the adhesion between the bamboo strips and facilitating bamboo stacking.

[0126] The working method of the bamboo shavings preparation production line for bamboo oriented strand board of the present invention:

[0127] The electrical devices of this invention can be communicatively connected to existing control systems for unified control, or each device can be controlled by a separate control system. For example, a PLC can be used as the control system.

[0128] (1) The bamboo material preparation and stacking equipment 40 has two whole bamboo feeding mechanisms, two whole bamboo conveyors 404, two bamboo splitting machines (excluding inner nodes) 401, two bamboo strip combination conveying devices 402, and one bamboo strip stacking machine 403.

[0129] Start-up preparation: Fresh long bamboo raw materials are transported to the stacking platform of the material yard. The long bamboo on the left stacking platform faces right, and the long bamboo on the right stacking platform faces left. Preferably, all bamboo are of the same length. Once all equipment is ready, the equipment is powered on and ready to run. The grippers of the twelve bamboo strip auxiliary transport robots 4015 are opened.

[0130] The whole bamboo loading mechanism (not shown) picks up a long bamboo from the bamboo stacking platform and loads two long bamboos onto the two whole bamboo conveyors 404 located on the left and right respectively. The whole bamboo loading mechanism is existing technology equipment.

[0131] (2) Two whole bamboo conveyors 404 located on the left and right sides of the production line are started, and the two bamboos move towards each other, transporting the long bamboo to the whole bamboo clamping device 4011. The whole bamboo conveyor 404 is about 17 meters long, and the bamboo being transported is 12-17 meters long. Preferably, all bamboos are the same length, around 15 meters. The whole bamboo conveyor 404 is an existing roller conveyor.

[0132] (3) The whole bamboo clamping and conveying devices 4011 located on the left and right sides, the upper roller conveyor 40112 presses the long bamboo 304 on the lower roller conveyor 40113, so that the long bamboo 304 quickly moves towards the bamboo splitting blade 40122 of the bamboo splitting disc 40121 for bamboo splitting processing, and the long bamboo is split into six bamboo strips 303. Since the bamboo has different diameters, the diameter of the head can reach 25-30cm, and the diameter of the tail is smaller, which is 3-4cm. Under the control of the whole bamboo outer diameter detector 40118, the first lower extension control component of the lower roller conveyor 40113 continuously and gradually lifts the tail end of the lower roller conveyor 40113 when splitting bamboo strips, so that the center line of the bamboo tube during bamboo splitting coincides with the center line of the bamboo splitting blade 40122 on the bamboo splitting disc 40121. The whole bamboo outer diameter measuring instrument 40118 and its circuit connection with the first lower telescopic control component are existing technologies.

[0133] (4) The bamboo splitting blades 40121 located on the left and right sides are fixedly connected to the bamboo splitting blades 40122. The bamboo splitting blades 40122 are six blades, which can cut the whole bamboo into six equal parts. The diameter of the head can reach 25-30cm, and the diameter of the small head and tail is smaller, 3-4cm, which can also be cut. One cut can cut the whole bamboo head and tail.

[0134] (5) The six long bamboo strips on the left and right sides, driven by the two whole bamboo clamping devices 4011, quickly pass through the bamboo strip guide and inner node removal device 4013 at their respective ends. In each of the six bamboo strip guide cavities 401311 (one end conical, one end arc-shaped, the bamboo strip guide cavities 401311 expanding evenly outwards), the bamboo strips expand outwards in all directions, guiding them through the first bamboo inner node storage space 401312 and the six first inner node removal blades 40132. Since the six inner node removal blades are installed according to the position of the inner node (bamboo partition) of the bamboo strip with a diameter of 8cm at the large end of the bamboo, the curvature of the blade of the first inner node removal blade 40132 is greater than the curvature of the bamboo, thus directly breaking the inner node 305 of the bamboo strip with a diameter less than 8cm. Then, it continues through the second bamboo inner section storage space 401313 and the six second inner section removal knives 40133. These six knives are positioned according to the thickness of the inner section of the bamboo strips, which are 25-17cm in diameter at the larger end of the bamboo. The radius of curvature of the blades of the second inner section removal knives 40133 is greater than the curvature of the bamboo, thus directly breaking the inner section 305 (partition) of the bamboo strip behind the bamboo. The first bamboo inner section storage space 401312 is used to accumulate bamboo inner sections during the production stage and to discharge accumulated bamboo inner sections at the end of the production stage. The second bamboo inner section storage space 401313 is used to accumulate bamboo inner sections during the production stage and to discharge accumulated bamboo inner sections at the end of the production stage. Two compressed air outlets are connected to two valves 4014 respectively, allowing a portion of the bamboo inner sections accumulated in the two bamboo inner section storage spaces to be discharged; when the entire bamboo splitting interval is completed, the bamboo partitions accumulated in the two bamboo inner section storage spaces fall off and are completely discharged. The bamboo strips continue to pass through their respective bamboo strip guide and inner node removal devices 4013, completely eliminating the inner nodes of the bamboo. They then continue through their respective bamboo strip positioning and transport components 40134, reaching the exit of the bamboo strip guide cavity 401311, where they continue to move parallel. The positioning of the bamboo strips by the bamboo strip positioning and transport components 40134 facilitates the subsequent grasping by the bamboo strip auxiliary transport robot 4015. Initially, the six bamboo strip auxiliary transport robots 4015 at the exit of the bamboo strip guide cavity 401311 are stacked together with their arms extended.

[0135] (6) The bamboo strip auxiliary transport robot 4015 is ready to operate on its respective track. All grippers of the six bamboo strip auxiliary transport robot 4015 are ready to operate and grab six bamboo strips. The auxiliary transport robot is positioned three meters away from each other to assist in the grabbing and operation, preventing the bamboo strips from deforming due to their length. First, the robot that is furthest from the bamboo strip guide device 4013 is the first robot and operates to grab six bamboo strips. When the first robot moves to the next three-meter position (actually six meters), the second auxiliary transport robot moves to grab six bamboo strips. When the first robot moves to the next three-meter position (actually nine meters), the fourth auxiliary transport robot moves to grab six bamboo strips. When the first robot moves to the next three-meter position (actually twelve meters), the fifth auxiliary transport robot moves to grab six bamboo strips. When the first robotic arm moves to the next three-meter (actually fifteen-meter) position, the sixth auxiliary transport robotic arm moves to grab six bamboo strips. Then, each group of six bamboo strip auxiliary transport robotic arms 4015 stops when they reach the designated position, opens their grippers, and drops the six bamboo strips onto the constant-speed belt conveyor 4021 below, ready to proceed to the next step. Then, all bamboo strip auxiliary transport robotic arms 4015 move back to their initial positions to await the next instruction.

[0136] (7) The bamboo strip combination transport devices 402, positioned vertically, collect the long bamboo strips from their respective constant-speed belt conveyors 4021. The constant-speed belt conveyor 4021, the accelerating belt conveyor 4022, the bamboo strip collection belt conveyor 4023, the telescopic belt conveyor 4024, the first limit rod 4026, the second limit rod 4027, the third limit rod 4028, and the bamboo strip filling sensor 4029 are all ready to start operation. The two sets of bamboo strip combination transport devices 402 operate in parallel vertically. Using two telescopic belt conveyors 4024, the bamboo strips are stacked vertically on the stacking roller conveyor 4032 of the bamboo strip stacking machine 403. This fully utilizes the method of overlapping the large and small ends of the bamboo strips to solve the problem of unstable bamboo strip stacking, thus fully leveraging the characteristics of bamboo.

[0137] (8) The 4021 normal-speed belt conveyor is running, each carrying six bamboo pieces to the right (e.g., ...). Figure 7(As shown). The first limit lever 402626 rises and falls periodically, allowing at most one bamboo strip to enter the accelerating conveyor belt 4022 at a time. When the bamboo strip color video monitor 40213 detects that the long bamboo strip on the accelerating conveyor belt 4022 is not green (i.e., yellow bamboo facing up and green bamboo facing down), the first limit lever 402626 and the second limit lever 4027 remain in the rising state, blocking the next long bamboo strip from running. The long bamboo strip with the yellow bamboo facing up is accelerated by the accelerating conveyor belt 4022 until it stops at the second limit lever 4027. The flipping arm 40211 flips counterclockwise once to turn the long bamboo strip with the yellow bamboo facing up over. Then the second limit lever 4027 is lowered, and the bamboo strip enters the bamboo strip collection conveyor 4023; then the first limit lever 402626 returns to its periodic rising and falling position, allowing the bamboo strips of the normal speed conveyor belt 4021 to enter the accelerating conveyor belt 4022 one by one. In the bamboo strip gathering belt conveyor 4023, the bamboo strips under the bamboo strip height limit plate 4025 are piled up (based on the point where one end of the bamboo strip is full). When the bamboo strip fullness sensor 4029 detects that a row of bamboo strips has reached the stacking width of the bamboo strip stacker 403, the third limit rod 4028 is lowered. This row of bamboo strips that has reached the stacking width is then placed into the bamboo strip stacker 403 under the combined action of the bamboo strip gathering conveyor 23 and the telescopic belt conveyor 4024, completing one layer of laying work, and then proceeding to the next row of laying work. Multiple water atomizing nozzles 4035 are opened to spray a layer of water film onto the bamboo green and bamboo yellow on the surface of the bamboo strips 303, increasing the connection between the bamboo strips, making the bamboo strips easier to slice, and reducing kinetic energy consumption. The upper and lower sets of bamboo strip combined transport devices 402 operate alternately, so that the bamboo strip stacker 403 ( Figure 4 As shown, the larger end of one layer of bamboo strips is laid on the left, and the larger end of the next layer of bamboo strips is laid on the right. As the amount of bamboo strips laid increases, the laying height increases. The lifting platform 4031 below the stacking roller conveyor 4032 of the bamboo strip stacker 403 descends to the optimal position (i.e., descends the height of one layer of bamboo strips) to continue the bamboo strip laying work. It is ensured that the bamboo core of each bamboo strip is placed facing down.

[0138] (9) Repeat steps (1) to (8) until the bamboo strip laying height reaches the next point of the height limit baffle of the bamboo shavings preparation production line of bamboo oriented structure particleboard. This indicates that the entire bamboo strip stacker 403 is full.

[0139] (10) The lifting platform 4031 of the bamboo chip stacker 403 descends to the lowest working position. The left stacking pressure roller assembly 4033 and the right stacking pressure roller assembly 4034 press slightly inward. The rollers of the stacking roller conveyor 4032, the pressure rollers of the left stacking pressure roller assembly 4033 and the pressure rollers of the right stacking pressure roller assembly 4034 operate, feeding the stacked bamboo chips 30 into the feeding and conveying device 1, and transporting them to the bamboo shavings preparation process. Steps (1) to (10) are repeated continuously to complete the bamboo chip stacking task.

[0140] (11) Fresh moso bamboo (bamboo) is first split into bamboo strips on a bamboo material preparation and stacking equipment, and then the bamboo strips are automatically stacked into a stack shape by a bamboo strip stacker. The stacked bamboo strips 30 are fed into the feeding and conveying device 1 by the bamboo strip stacker 403. The blade ring 31 of the rotary slicing and slicing machine 3 slides to the rightmost end to wait for operation (for ease of description, it is specified that the feed is radially from right to left). All the upper pressure rollers 223 and side pressure rollers 221, upper pressure plate 224, and side pressure plate 222 of the transition heavy pressure clamping device 2 return to the working starting position. The protective clamp 4 for the sliced ​​bamboo strip stack moves to the left waiting position.

[0141] (12) Feeding of stacked bamboo strips 30: The feeding roller conveyor 11 of the feeding and conveying device 1 is started, and the bamboo strips in the stacked bamboo strips 30 that are lower than the height limit baffle 14 pass through.

[0142] (13) When the transition heavy clamping device 2 gives a signal instruction to the feeding conveyor 1 that there is no stacked bamboo strip 30 (the sensor on the transition roller conveyor 21 detects whether there is bamboo strip), the feeding roller conveyor 11 will transport the stacked bamboo strip 30 into the transition roller conveyor 21.

[0143] (14) The stacked bamboo strips 30 continue to move forward. When the head of the stacked bamboo strips 30 is exposed at the discharge port of the transition roller conveyor 21, the cutting length sensor 36 detects that the bamboo strip has reached the predetermined cutting length position. The cutting length sensor 36 issues a positioning command, and the transition roller conveyor 21 stops transporting the stacked bamboo strips 30. The cutting length sensor 36 is a type of limit sensor, distance sensor, infrared sensor, digital sensor, etc.

[0144] (15) The side-push assembly of the transition pressure clamping device 2 drives the side pressure plate 222 of the side pressure bracket to clamp the side pressure roller 221 towards each other. At the same time, the upward push assembly drives the upper pressure plate 224 of the upper pressure bracket and the upper pressure roller 223 to clamp the stacked bamboo strips 30 downward, so as to prevent the stacked bamboo strips 30 from vibrating when being sliced, which would affect the quality of the sliced ​​bamboo shavings. Note: The bamboo skin is very smooth. If it is not clamped, it will shake when slicing.

[0145] After the transition pressure clamping device 2 clamps the stacked bamboo strips 30, the bamboo strip stack protective clamp 4 slides to the right within its own track 47, encasing the stacked bamboo strips 30 to be sliced. The bamboo strip stack support plate 43 and the bamboo strip stack auxiliary pressure plate 44 are located on the upper and lower sides of the stacked bamboo strips 30, respectively. The first lifting mechanism 45 raises the bamboo strip stack support plate 43, and the second lifting mechanism 46 gently presses the bamboo strip stack auxiliary pressure plate 44 downwards, holding the head of the stacked bamboo strips 30 to be sliced.

[0146] The bamboo support plate 37 is positioned to the left between the bamboo slice stack support plate 43 and the bamboo slice stack auxiliary pressure plate 44. Driven by the existing pushing device 371, the bamboo support plate 37 abuts against the head of the stacked bamboo slices 30 that come out from the transition heavy pressure clamping device 2. In this way, only one side of the stacked bamboo slices 30 is open and faces the blade ring 31 of the rotary cutter for rotary cutting slices.

[0147] (16) Rotary slicing machine 3 starts: Motor 34 starts running, and bamboo support plate 37 abuts against the left side of stacked bamboo strips 30 to prevent deformation and vibration of the exposed stacked bamboo strips 30 when the blade ring and cutter disc 31 are working. The blade ring and cutter disc 31 rotates at high speed, and the bamboo strips are cut by the cutting blade assembly 32 and the slicing blade assembly 33 installed on the outside of the blade ring and cutter disc 31. The blade ring and cutter disc 31 moves to the left on the first slide 35 to achieve fixed thickness and fixed length cutting. Figure 8 The cutter ring 31 slides from its rightmost standby position to its leftmost position, rotary cutting and slicing the exposed stacked bamboo strips 30 one by one. The bamboo shavings pass through the bamboo shaving channel 311 inside the cutter ring 31 and exit through the bamboo shaving discharge port 312 in the middle. Under the action of the impeller feed ring 313, the bamboo shavings smoothly pass through the bamboo shaving discharge port 312 and enter the bamboo shaving guide chamber 38, then fall onto the bamboo shaving conveyor 6 below. After completing one rotary cutting task, the first slide 35 drives the cutter ring 31 to quickly return to its initial waiting position on the right, awaiting the next slicing instruction. The bamboo strip stack protective clamp 4 slides to the left to its starting position, also awaiting the next protective instruction. The bamboo support plate 37 also moves to the left to its initial position, also awaiting the next instruction to abut against the stacked bamboo strips 30. At this time, the distance measurement instruction of the slicing length sensor 36 is reset to zero. Send the running command to the transition roller conveyor 21 again.

[0148] (17) The transition roller conveyor restarts: All the upper pressure rollers 223, side pressure rollers 221, upper pressure plate 224, and side pressure plate 222 of the transition heavy-duty clamping device 2 move to the starting position and release the stacked bamboo strips 30. The motors (not shown) of the transition roller conveyor 21 and all the upper pressure rollers 223 and side pressure rollers 221 are powered on and run, with each roller rotating at the same speed. The head of the stacked bamboo strips 30 is fed back into the discharge port of the transition roller conveyor 21 until the head of the stacked bamboo strips 30 reaches the detection position of the cutting length sensor 36, at which point the motors (not shown) of the transition roller conveyor 21 and all the side pressure rollers 221 and upper pressure rollers 223 stop. Repeat steps (14), (15), (16), and (17) until the front section of the entire stacked bamboo strip 30 is shaved into bamboo shavings. As the tail of the stacked bamboo strip 30 continues to move towards the discharge port of the transition roller conveyor 21, the remaining stacked bamboo strip 30 will fall directly into the bamboo waste collection bin 5 below because the side pressure rollers 221, side pressure plates 222, upper pressure rollers 223, and upper pressure plates 224 cannot hold it, and will be transported out by the bamboo waste conveyor 51. Unshaved bamboo strips can be placed in the middle of the stacked bamboo strip 30 to fill the gaps when stacking long bamboo strips next time.

[0149] (18) Repeat steps (11)(12)(13)(14)(15)(16)(17) continuously, and work continuously to turn multiple stacked bamboo strips 30 into bamboo shavings.

[0150] (19) Start-up of bamboo shaving conveyor 6: Bamboo shaving conveyor 6 collects bamboo shavings below the shavings bin of rotary shaving machine 3 and transports them to shavings screening machine for screening.

[0151] (20) Start-up of the wood shavings screening machine: The wood shavings screening machine is a piece of existing technology and can be one or a combination of vibrating screen, disc screen, and mesh screen. The wood shavings screening machine is started and runs to remove dust and granular bamboo chips from the bamboo shavings material. The bamboo shavings that meet the size requirements are discharged from the discharge port of the screening machine and sent to the bamboo strip flotation machine below it.

[0152] (21) Start-up of the bamboo strip flotation machine: Bamboo shavings are discharged from the outlet of the screening machine and enter the inlet of the oil flotation tank 81 below it. Under the stirring of the flotation washing drum 82, the bamboo shavings enter the oil flotation tank 81. Since the density of oil is 0.8-0.9 g / cm³, the bamboo shavings enter the oil flotation tank 81. 3 The density of bamboo green skin strips is greater than 0.9 g / cm³. 3The bamboo strips slowly descend onto the bamboo strip collection belt conveyor 85 at the bottom of the oil flotation tank 81. The bamboo strip collection belt conveyor 85 and the scraper conveyor 86 are then started, and the bamboo strips are fed onto the scraper conveyor 86 and then sent outside the oil flotation tank 81 for processing, thus no longer affecting the qualified bamboo shavings. The qualified bamboo shavings 302 have a low density and float to the surface of the oil. The first bamboo shavings collecting mesh conveyor 84 and the first scraper conveyor 83 are started. The scraper scrapes the floating qualified bamboo shavings 302 and transports them to the first bamboo shavings collecting mesh conveyor 84. The first bamboo shavings collecting mesh conveyor 84 carries the qualified bamboo shavings 302 out of the oil flotation tank 81 and into the ultrasonic generator tunnel chamber 841. The qualified bamboo shavings are first subjected to ultrasonic cavitation treatment in the ultrasonic generator tunnel chamber 841. Under the action of ultrasound, the pores of the bamboo shavings are enlarged and the starch in the bamboo cells is removed. Then the qualified bamboo shavings 302 are sent to the hot water tank 91 of the boiling device 9 by the first bamboo shavings collecting mesh conveyor 84.

[0153] When the heating plate 88 is energized, the density of the oil at the top of the flotation oil tank decreases, causing the bamboo strips to descend more quickly. The oil has a density of 0.8-0.9 g / cm³. 3 Vegetable oils, recycled light edible oils, and industrial waste oils such as heat transfer oils are processed. A bamboo strip barrier 87 prevents the bamboo strips from settling in the gap between the bamboo strip collection conveyor belt 85 and the oil flotation tank 81, thus preventing equipment malfunctions. When there is a large amount of fouling at the bottom of the oil tank, the first valve 89 of the first drain outlet 811 is opened to discharge the fouling into the flotation tank.

[0154] The selected qualified bamboo shavings 302 enter the inlet of the hot water tank 91 of the boiling device 9. Under the stirring of the bamboo shavings pressing drum 92, the bamboo shavings are heated in the hot water of the hot water tank 91 at 70-80℃ for 5-15 minutes. When the bamboo shavings are heated, the hot water dissolves some of the starch inside and outside the bamboo cells (here, the starch outside the bamboo cells refers to the starch cavitation by ultrasound); at the same time, the moisture content of the bamboo increases, which is in preparation for unifying the subsequent process parameters.

[0155] The second bamboo shavings collecting conveyor belt 94 and the second scraper conveyor 93 are started. The scraper conveyor 93 collects qualified bamboo shavings 302 and sends them into the second bamboo shavings collecting conveyor belt 94, and then into the feed inlet of the cooking and carbonization chamber 10. When a lot of dirt is generated at the bottom of the hot water tank 91, the second valve 95 of the second drain outlet 911 is opened to discharge the dirt from the hot water tank 91.

[0156] The main purpose of the boiling device 9 is to balance the moisture content and unify the subsequent process parameters; hot water dissolves some of the starch inside and outside the bamboo cells; at the same time, it increases the moisture content of the bamboo so that more starch inside the bamboo cells can be dissolved during steaming and carbonization.

[0157] (22) Cooking and carbonization: When bamboo shavings are needed in the cooking and carbonization chamber 10, a start command is given to the second bamboo shavings collection mesh belt conveyor 94. The second bamboo shavings collection mesh belt conveyor 94 starts running and sends the qualified bamboo shavings 302 into the cooking and carbonization chamber 10 for modification treatment.

[0158] The cooking and carbonization chamber 10 also has a vibrator to provide vibration function. With the steam system activated, the cooking temperature of the bamboo shavings is 80–110℃, and the cooking time is 6–15 minutes. This softens the bamboo, relatively enlarges the pores, removes starch from the bamboo cells, improves the bamboo's mold resistance, and enhances its permeability. The qualified bamboo shavings 302 after cooking and carbonization are fed by the feeder 102 and discharged into the outlet of the cooking and carbonization chamber 10, entering the dewatering mesh belt conveyor 201. The bamboo shavings are then preliminarily filtered to remove cooking water in the dewatering mesh belt conveyor 201, and finally, the qualified bamboo shavings are sent to the bamboo shaving drying kiln 20 for drying.

[0159] (23) Finally, the bamboo shavings after the cooking water has been filtered out are sent to a drying kiln for drying. After the bamboo shavings that have undergone cooking and carbonization are dried to 4-7%, they are placed in a drying shavings silo for later use.

[0160] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
