Description

Technical Field

[0001] The present invention relates to the technical field of bamboo processing, and particularly to an integrated bamboo shaving and slicing machine for bamboo processing. Background Art

[0002] As a renewable and environmentally friendly material, bamboo has important application values in the fields of construction, furniture, handicrafts, etc. With the development of deep processing technology of bamboo, its processing process has shifted from traditional rough processing to refined processing, such as slicing, carbonization, anti-corrosion, and lamination processes. For example, the preparation process of the bamboo bundle fiber tube air odor purification package developed by the applicant requires first making the bamboo into fiber bamboo bundles, and then forming a porous microstructure through carbonization to achieve the odor purification function, which puts higher requirements on the pretreatment of bamboo.

[0003] During the pretreatment process of bamboo, its surface layer (bamboo green) contains wax, silica, and a dense fiber layer, which will not only significantly reduce the gluing performance and the permeability of anti-corrosion treatment, but also cause difficulty in forming filaments during the processing of fiber bamboo bundles. Research shows that scraping off the bamboo rind layer with a thickness of 0.2 mm - 0.7 mm on the surface of bamboo can effectively remove surface impurities and expose the internal fiber structure, thereby significantly improving the subsequent gluing strength and the absorption rate of preservatives. In addition, the scraped bamboo rind is rich in active ingredients such as bamboo juice and polysaccharides, which can be reused as Chinese herbal medicines or biomass raw materials and have economic value.

[0004] However, the existing bamboo processing equipment has obvious deficiencies: Firstly, conventional slicing equipment directly cuts untreated raw bamboo, resulting in the residual bamboo rind layer on the surface of the sliced bamboo pieces. Additional grinding or chemical treatment steps are required in the gluing process, which not only increases energy consumption and costs, but may also cause quality problems due to uneven treatment; Secondly, although a small number of bamboo shaving equipment can remove the bamboo green alone, it relies entirely on manual operation throughout the process, and the bamboo needs to be transported to the slicing equipment for secondary processing later. The separation of processes leads to low efficiency, and the connection of multiple links may also exacerbate the loss of bamboo. Therefore, there is an urgent need to develop a bamboo processing equipment that integrates the functions of bamboo shaving and slicing to solve the above problems. Summary of the Invention

[0005] In order to overcome the problems of high manual dependence and easy residue during bamboo rind scraping in the existing bamboo processing equipment, as well as low efficiency and material loss caused by the separation of processes, the present invention provides an integrated bamboo shaving and slicing machine for bamboo processing, which realizes continuous operation of precise bamboo shaving on the surface of bamboo and automatic slicing processing through an integrated structure design.

[0020] Advantages of the present invention:

[0021] 1. Continuous and efficient processing: Through the integrated layout of the bamboo shaving mechanism and the slicing mechanism, continuous operations of bamboo shaving and slicing on the bamboo surface are realized. After the bamboo is centered by the rolling ball guide, the rotating disk drives the first scraper to rotate at a high speed to accurately scrape the bamboo shaving layer on the surface. Subsequently, the slicing mechanism quickly slices through the replaceable cutting blade. There is no need for manual transfer throughout the process, the process connection is tight, the processing efficiency is improved, and the material loss rate is reduced.

[0022] 2. Precise and controllable scraping depth: In the scraping mechanism, the radial distance difference between the rolling ball and the first scraper can be adjusted by the bolts of the limiting cylinder and the connecting plate. Combined with the first spring pushing the rolling ball to make it close to the radial direction of the bamboo, it ensures that the scraper always scrapes the bamboo surface at a set distance. This design not only adapts to bamboo with different diameters but also avoids uneven scraping depth caused by fluctuations in bamboo size.

[0023] 3. Optimization of multi-scenario adaptability: For bamboo with larger bamboo knots, the staggered second scrapers and spring buffer structures can be used to pre-scrape the bamboo knot protrusions in advance to ensure stable depth during the subsequent operation of the first scraper; the slicing mechanism adopts a modular fixed ring design. By replacing the fixed rings with different numbers of cutting knives, the number of slices can be flexibly adjusted (such as 2 slices, 4 slices, 6 slices, etc.) to meet diverse processing requirements.

[0024] 4. Bamboo rind recycling and resource utilization: The scraped bamboo rind is centrally collected, and its active ingredients such as bamboo juice and polysaccharides can be directly used as traditional Chinese medicine materials or biomass raw materials to achieve efficient resource utilization.

[0025] 5. High degree of automation: Through the cooperation of the spring, rolling ball and guide block in the scraping mechanism, the scraping thickness is dynamically adjusted according to the ring diameter of the bamboo. The whole process does not require manual intervention in bamboo positioning and scraping depth adjustment, greatly reducing the dependence of the equipment on labor and avoiding quality fluctuations caused by human operation errors.

Detailed implementation mode

[0035] The present invention will be further described below in conjunction with the drawings and embodiments.

[0036] Embodiment 1: Please refer to Figure 1 - Figure 3 、 Figure 6 、 Figure 7 , which is one of the structures of the bamboo shoot scraping and slicing integrated machine provided by the present invention, includes a mounting base plate 1, and further includes a bamboo shoot scraping mechanism and a slicing mechanism. A bamboo shoot scraping mechanism for scraping the bamboo shoots on the surface of bamboo is arranged on the top of the mounting base plate 1, and a slicing mechanism for dividing the bamboo is arranged on the top of the mounting base plate 1.

[0037] The bamboo rind scraping mechanism includes a first bracket 21, which is fixedly connected to the top of the installation base plate 1. A rotating ring 22 is rotatably connected to the inside of the first bracket 21 through a bearing. A rotating disk 23 is fixedly connected to the right side of the rotating ring 22. Inside the rotating disk 23, three evenly distributed tool holders 24 are slidably connected towards the center inside the rotating disk 23. Of course, in other embodiments of the present application, the number of tool holders 24 can be one or more. A first scraper 25 for scraping the bamboo rind on the surface of the bamboo is fixedly connected to the inner side of the tool holder 24. A connecting plate 26 connected by bolts is arranged on the right side of the tool holder 24. A limiting cylinder 27 is fixedly connected to the right side of the connecting plate 26. A rolling ball 28 is arranged inside the limiting cylinder 27. A threaded hole is opened inside the tool holder 24, and a rectangular through slot with a corresponding size is opened at the corresponding position of the connecting plate 26 in the threaded hole. By passing a bolt through the rectangular through slot and then screwing it into the threaded hole, the height of the rolling ball 28 can be adjusted according to the required scraping depth, and the staggered distance between the rolling ball 28 and the first scraper 25 can be adjusted. In this embodiment, the distance from the top of the first scraper 25 to the center of the rotating disk 23 is 0.6 mm different from the distance from the top of the rolling ball 28 to the center of the rotating disk 23. The bamboo to be processed is conveyed by a conveying device, so that the bamboo first contacts the rolling ball 28. The rolling ball 28 is pushed open by the bamboo to drive the limiting cylinder 27. The limiting cylinder 27 drives the tool holder 24 through the connecting plate 26. The tool holder 24 slides to drive the first scraper 25, so that the first scraper 25 adjusts together with the rolling ball 28. Then, while the bamboo passes through, the rotating ring 22 drives the rotating disk 23 to rotate. The rotating disk 23 drives the first scraper 25 to rotate through the tool holder 24. Thus, while the first scraper 25 rotates around the bamboo, a layer of bamboo rind about 0.6 mm thick is scraped off the surface of the bamboo. Then, the bamboo enters the slicing mechanism, and the bamboo is evenly sliced by the slicing mechanism. A limiting rod 29 is fixedly connected to the inside of the rotating disk 23. A limiting hole is opened at the corresponding position of the tool holder 24 in the limiting rod 29. The tool holder 24 is slidably connected to the outside of the limiting rod 29. A first spring 210 is fixedly connected between the tool holder 24 and the rotating disk 23. A motor bracket 211 is fixedly connected to the top of the first bracket 21. A driving motor 212 is fixedly connected to the inside of the motor bracket 211. The output end of the driving motor 212 is fixedly connected to a first gear 213. A second gear 214 is meshed with the outside of the first gear 213. The second gear 214 is fixedly connected to the left side of the rotating ring 22. The first spring 210 can make the tool holder 24 automatically reset, so that the first scraper 25 continuously fits the bamboo, and fully scrapes the bamboo rind through cooperation and rotation, and can be applied to bamboos with large size changes. A limiting hole is opened at the corresponding position of the tool holder 24 in the limiting rod 29, and the tool holder 24 slides on the outside of the limiting rod 29 through the limiting hole. The limiting rod 29 can be connected to the tool holder 24 through the limiting hole, avoiding the tool holder 24 from detaching, and avoiding the tool holder 24 from shifting and causing jamming, making the up and down sliding of the tool holder 24 smoother.

[0038] The slicing mechanism includes a third support 41, which is fixedly connected to the top of the mounting base plate 1. Inside the third support 41, there is a connecting cylinder 42 fixedly connected. On the left side of the connecting cylinder 42, there is a guiding cylinder 43 fixedly connected. Symmetrically and fixedly connected to the outside of the connecting cylinder 42 are two fixing plates 44. On the right side of the fixing plate 44, there is a second screw 45. Threaded on the outside of the second screw 45 is a fourth nut 46. Inside the connecting cylinder 42, there is a movable fixing ring 47 sleeved on the outside of the second screw 45. Inside the fixing ring 47, there is a cutting knife 48 fixedly connected. The bamboo material after scraping the bamboo rind is divided into four pieces by the cutting knife 48, which facilitates subsequent processing. Moreover, the fixing ring 47 with different numbers of cutting knives 48 can be replaced according to needs, so that the bamboo material can be divided into several pieces. At the corresponding position of the connecting cylinder 42 with respect to the fixing ring 47, there is a card slot, and the fixing ring 47 is snap-fitted inside the card slot. The fixing ring 47 is positioned by the card slot, which facilitates the installation of the fixing ring 47 and prevents the fixing ring 47 from falling off. The connecting cylinder 42 and the rotating disk 23 are concentrically arranged. The concentric arrangement enables the bamboo material to be processed smoothly in sequence, avoiding the bamboo material from tilting and deviating from the predetermined path. In this embodiment, the cutting knife 48 has two blades in a cross shape and can divide the bamboo material into four pieces. Of course, in other embodiments of the present application, the number of blades of the cutting knife 48 can be adjusted according to actual situations, such as one blade, three blades, etc.

[0039] Embodiment 2: Please refer to Figure 1 , Figure 4 - Figure 6 , Figure 8 , in the specific structure of the bamboo material processing and scraping and slicing integrated machine in this embodiment, it includes a mounting base plate 1, and also includes a scraping mechanism and a slicing mechanism. On the top of the mounting base plate 1, there is a scraping mechanism for scraping the bamboo rind on the surface of the bamboo material, and on the top of the mounting base plate 1, there is a slicing mechanism for dividing the bamboo material.

[0040] The structure of the slicing mechanism in this embodiment is the same as that in the embodiment. The difference is that the bamboo shaving mechanism in this embodiment includes a second bracket 31. The second bracket 31 is fixedly connected to the top of the mounting base plate 1. A circular frame 32 is fixedly connected to the top of the second bracket 31. The circular frame 32 has an inner ring and an outer ring. Six first screws 33 are inserted on the inner ring and the outer ring of the circular frame 32. First nuts 34, second nuts 35 and third nuts 36 are threadedly connected to the first screws 33 from the outside to the inside. A second spring 38 and a gasket 37 are also sleeved between the second nuts 35 and the third nuts 36 on the first screws 33. The first nuts 34 and the second nuts 35 are located outside the outer ring. One end of the second spring 38 abuts against the inner side of the outer ring, and the other end abuts against the gasket 37. The gasket 37 abuts against the third nut 36 under the elastic force of the second spring 38. The third nut 36 abuts against the outer side surface of the inner ring. A second scraper 39 is fixedly connected to the top of the first screw 33 located inside the inner ring. A guide block 310 is fixedly connected to the right side of the first screw 33. In this embodiment, the distance from the top of the second scraper 39 to the center of the circular frame 32 is 0.6 mm shorter than the distance from the top of the guide block 310 to the center of the circular frame 32, so that the second scraper 39 can scrape off bamboo shaving about 0.6 mm thick on the surface of the bamboo. A T-shaped groove is formed inside the circular frame 32, and a groove corresponding to the T-shaped groove is formed inside the first screw 33. The first screw 33 slides inside the T-shaped groove through the groove. The first screw 33 is limited by the T-shaped groove to prevent the first screw 33 from rotating, so that the second scraper 39 is always in a parallel state. The connecting cylinder 42 and the circular frame 32 are concentrically arranged. There are two circular frames 32, and the two circular frames 32 are coaxially arranged. The first screws 33 inside the two circular frames 32 are staggered. The first screws 33 are staggered to cover the surface of the bamboo with a corresponding size, so that the bamboo with a corresponding size can be fully scraped. The bamboo shaving mechanism in this embodiment is applicable to bamboos corresponding to the radian size of the second scraper 39 or with relatively small size changes.

[0041] Embodiment 3: Please refer to Figure 1 , Figure 6 , in this embodiment, the bamboo shaving mechanisms of Embodiment 1 and Embodiment 2 are used together, and the bamboo shaving mechanism of Embodiment 2 is in the front stage of the process, the bamboo shaving mechanism of Embodiment 1 is in the middle stage of the process, and the slicing mechanism is in the latter stage of the process.

[0042] At the same time, the top of the second scraper 39 is flush with the top of the guide block 310, and the distance from the top of the first scraper 25 to the center of the rotating disk 23 is 0.6 mm different from the distance from the top of the rolling ball 28 to the center of the rotating disk 23; at this time, the second scraper 39 can first scrape off the joints of the bamboo, so that the circumferential diameter size of the bamboo surface is uniform, so as to avoid the joints of the bamboo affecting the cutting depth of the first scraper 25, and enable the first scraper 25 to stably scrape off the bamboo shaving 0.6 mm deep on the surface of the bamboo.

[0043] When working, the mounting base plate 1 is fixed on the bamboo conveying device through bolts, so as to fix the overall position of the device. When processing bamboo with a small difference in arc size from the second scraper 39, directly use the bamboo processing and scraping and slicing integrated machine shown in Embodiment 2 for operation. The bamboo is conveyed by the conveying device, so that the bamboo first contacts the guide block 310. The guide block 310 is pushed by the bamboo, and the guide block 310 will drive the first screw 33 to slide and compress the second spring 38 at the same time. Then the bamboo passes through the second scraper 39, so that the bamboo wool on the surface of the bamboo is scraped off by the staggered second scrapers 39.

[0044] When facing bamboo with a large difference in head and tail ring diameter sizes, preferably use the bamboo processing and scraping and slicing integrated machine shown in Embodiment 3 for operation. Make the bamboo first pass through the circular frame 32, and use the second scraper 39 to scrape off the joints of the bamboo. Then the bamboo contacts the rolling ball 28 again. The rolling ball 28 is squeezed by the bamboo and will push the rolling ball 28. The rolling ball 28 drives the connecting plate 26 through the limiting cylinder 27, and the connecting plate 26 drives the tool holder 24 to slide outside the limiting rod 29, and compress the first spring 210 at the same time. Then while the bamboo passes through, the driving motor 212 drives the first gear 213, the first gear 213 drives the second gear 214, the second gear 214 drives the rotating ring 22, the rotating ring 22 drives the rotating disc 23, and the rotating disc 23 drives the first scraper 25 to rotate around the bamboo through the tool holder 24, so as to scrape off the bamboo wool on the surface of the bamboo.

[0045] Of course, it is also possible to use the bamboo processing and scraping and slicing integrated machine shown in Embodiment 1 alone for operation. This solution can solve the problem that the fixed-arc scraper shown in Embodiment 2 is applied to bamboo with a large difference in size, resulting in insufficient scraping of bamboo wool.

[0046] When the bamboo processing and scraping and slicing integrated machine of the present application is working, a collection box is placed at the corresponding position of the scraping mechanism by manual to collect bamboo wool. The bamboo after scraping continues to move to the left, and then is divided into pieces (in this embodiment, divided into four pieces) when passing through the cutting knife 48, and then is output through the connection cylinder 42 and the guide cylinder 43.

[0047] Twist the fourth nut 46 to unscrew it from the outside of the second screw 45, and then the fixing ring 47 can be removed from the outside of the second screw 45, so as to replace the fixing ring 47, so as to replace the fixing ring 47 with different numbers of cutting knives 48. The collection of bamboo wool is a common means in the prior art, so it will not be described in too much detail.

[0048] Through the above steps, the depth of scraping can be controlled by the rolling ball 28 and the guide block 310, and the first scraper 25 rotates around the bamboo at a high speed through the rotation of the rotating disc 23, so as to fully scrape off the bamboo wool on the surface of the bamboo.
