[0024] like Figures 1-7As shown, the present invention discloses an apparatus for preparing bamboo fiber mulch film, including a main body 1. The main body includes at least two panels arranged in parallel front to back. A storage tank 2 is installed on the lower side of the main body 1. The storage tank 2 is used to store fallen bamboo fibers. After the bamboo fibers are soaked in the liquid in the storage tank 2, they are then treated with adhesive to further obtain the raw materials for forming mulch film. The specific forming process belongs to the prior art and can be understood by those skilled in the art.
[0025] As a further improvement of this invention, a horizontal crushing roller 3 is installed at the front end of the device body. The initial movement force of the bamboo in the crushing roller 3 can be achieved manually or by other push-pull mechanisms, allowing the bamboo to move from right to left. A slicing component 4 is installed at the front end of the crushing roller 3. The slicing component 4 is used to cut the bamboo tube into strips for subsequent bamboo fiber processing. A feeding component 5 is installed at the bottom of the crushing roller 3. A crushing component 6 is installed on the upper side of the crushing roller 3. The crushing component 6 works with the crushing roller 3 to crush the bamboo. A fiber-splitting component 7, a first conveying component 8, a second conveying component 9, and a cutting component 10 are arranged sequentially at the rear end of the crushing roller 3. The first conveying component 8 and the second conveying component 9 also provide conveying force for the bamboo fibers, facilitating subsequent overall cutting operations to obtain bamboo fibers of relatively uniform length. The feeding component 5 is used to convey the bamboo fibers to the fiber-splitting component 7, which is used to split the bamboo fibers into fibers. The cutting component 10 is used to cut the bamboo fibers.
[0026] The device disclosed in this invention directly separates and cuts the bamboo fibers after crushing, resulting in a smooth overall operation process that requires no additional manual intervention, thus greatly improving the efficiency of mulch film production. By crushing the bamboo, separating it into fibers, and then cutting it, the uniformity of most of the bamboo fibers is effectively ensured, resulting in bamboo fibers with uniform morphology and appropriate length, meeting the process requirements for producing high-quality bamboo fiber mulch films.
[0027] In this embodiment, the crushing assembly 6 includes a roller 11, a first rotating shaft 12, a first bearing seat 13, a first rotation drive device 14, and a hammering assembly. The roller 11 is connected to the first rotating drive device 14 via the first rotating shaft 12. The first rotating shaft 12 is rotatably mounted on the first bearing seat 13, which is connected to a horizontal displacement drive device. The hammering assembly is installed inside the roller 11. This invention improves the efficiency of bamboo fiber production by using the roller 11 to crush bamboo and then employing the combination of the hammering assembly.
[0028] In this embodiment, the hammering assembly includes a second rotating shaft 15, a second bearing seat 16, a second rotating drive device 17, a cam 18, a support wheel 19, a guide rod 20, a hammer head 21, a limiting block 22, and an elastic support device 23. The second rotating shaft 15 is coaxially rotatably connected to the roller 11, and the end of the second rotating shaft 15 away from the roller 11 is connected to the second rotating drive device 17. The second rotating shaft 15 is rotatably mounted on the second bearing seat 16. The cam 18 is located inside the roller 11 and is fixedly mounted on the second rotating shaft 15. A through hole 24 is opened on the surface of the roller 11, and the hammer head 21 is slidably mounted in the through hole 24. The hammer head 21 is connected to the support wheel 19 through the guide rod 20. The guide rod 20 is slidably mounted in the limiting block 22 fixed inside the roller 11 along the radial direction of the roller 11. The elastic support device 23 is supported between the limiting block 22 and the support wheel 19, and the support wheel 19 is in contact with the surface of the cam 18. When the cam 18 and the roller 11 rotate relative to each other, the cam 18 acts on the support wheel 19, causing the support wheel 19 to drive the hammer head 21 through the guide rod 20. The hammer head 21 can then pound the bamboo outside the through hole 24, which is more conducive to the formation of bamboo fibers. The combination of crushing and pounding not only reduces the number of process steps and effectively improves production efficiency, but also makes the bamboo fiber formation process smoother and reduces the occurrence of debris.
[0029] In this embodiment, an arc-shaped compaction groove 25 is formed on the upper side of the compaction roller 3. A strip-shaped through groove 26 is provided on the compaction groove 25. The through groove 26 can be used to pass bamboo fibers. The length of the through groove 26 is between 10 and 30 mm, which can allow some bamboo fibers to pass through in time, facilitating the smooth operation of the device. A hydraulic support device 27 is installed at the bottom of the storage tank 2. The output end of the hydraulic support device 27 is connected to the compaction roller 3. By setting the hydraulic support device 27, the gap between the compaction roller 3 and the roller 11 can be adjusted at any time, which is beneficial to the rapid formation of bamboo fibers.
[0030] In this embodiment, the slicing assembly 4 includes a slicing frame 28, with a conveying hole 29 formed in the center of the slicing frame 28. A plurality of cutters 30 are fixedly fixed at uniform intervals along the circumference of the inner side of the conveying hole 29, and the cutters 30 extend radially inward along the conveying hole 29. The slicing assembly 4 has a simple structure, which facilitates rapid slicing of bamboo, and the force required to push the bamboo can be manually applied.
[0031] In this embodiment, the fiber splitting assembly 7 includes a fiber splitting block 31, a rotating shaft 32, a torsion spring 33, and a guide plate 34. The fiber splitting block 31 is rotatably mounted on the main body 1 of the device via the rotating shaft 32. A torsion spring 33 is also installed between the fiber splitting block 31 and the main body 1 of the device. A space for bamboo fiber to pass through is formed between the fiber splitting block 31 and the guide plate 34. The torsion spring 33 is used to provide elastic stress to the fiber splitting block 31 on the side facing the guide plate 34. Multiple fiber splitting channels 35 are opened on the end face of the fiber splitting block 31, which is more conducive to the fiber splitting operation before cutting.
[0032] In this embodiment, the first conveying component 8 and the second conveying component 9 have the same structure to ensure a continuous supply of bamboo fiber. Through the cooperation of the two sets of conveying components, it is ensured that the bamboo fiber does not twist or break during the transmission process. The first conveying component 8 includes a roller 36, a roller bracket 37, a first cylinder 38, a first cylinder bracket 39, and a conveying roller 40. The roller 36 is rotatably mounted on the roller bracket 37. The roller bracket 37 is connected to the first cylinder 38. Multiple first cylinders 38 are mounted side by side on the first cylinder bracket 39. The first cylinder bracket 39 is fixed on the main body 1 of the device. The conveying roller 40 has roller grooves 41 that correspond one-to-one with the roller 36.
[0033] In this embodiment, the cutting assembly 10 includes a cutter 30, a cutter bracket 43, a second cylinder 44, a second cylinder bracket 45, a cutter groove 46, and a groove support 47. The cutter 30 is connected to the second cylinder 44. Multiple second cylinders 44 are mounted side by side on the second cylinder bracket 45. The second cylinder bracket 45 is fixed on the device body 1. Multiple cutter grooves 46 are mounted side by side on the groove support 47. The groove support 47 is fixed on the device body 1. The cutter grooves 46 correspond one-to-one with the cutter 30.
[0034] The present invention has a steam injection component above the rolling mill 3. By spraying hot steam onto the bamboo, the long bamboo strips can be softened, which is more conducive to the rapid formation of bamboo fibers in the future.
[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
