Abstract
Description
Technical Field
[0001] This utility model relates to the field of bamboo leaf processing technology, and in particular to a bamboo leaf trimming mechanism. Background Technology
[0002] Reed leaves can be used as food packaging, such as for zongzi (sticky rice dumplings), and can also be used to process reed leaves into wine, animal feed, paper, and for extracting polysaccharides. Reed leaves also have medicinal properties and high medicinal value. When using reed leaves to wrap zongzi, the ends of the leaves need to be trimmed to remove unusable parts, making subsequent packaging easier.
[0003] For example, a bamboo leaf trimming mechanism disclosed in Chinese patent literature (publication number: CN222819199U) uses a pressing component to fix the bamboo leaves, which helps to improve the stability of the bamboo leaves during cutting. Then, the cutting component can cut the two ends of the bamboo leaves without the need for manual trimming by staff, which helps to improve the trimming efficiency of bamboo leaves.
[0004] However, when wrapping zongzi (sticky rice dumplings), the size of the reed leaves must be strictly matched with the size of the zongzi. For example, to wrap a 100g zongzi, the length of the reed leaves should be 25-30cm, while to wrap a 200g zongzi, it should be 35-40cm. However, the cutter of this device is fixed in position and can only cut a single length. It cannot flexibly adjust the cutting range according to the damage of the reed leaves. For leaves with yellow tips or broken edges, the fixed cutter will accidentally cut the usable part, resulting in material waste and reduced practicality. Utility Model Content

[0028] Example
[0029] like Figures 1-5 As shown, this utility model provides a technical solution: a bamboo leaf trimming mechanism, including a trimming table 1, which solves the problem of fixed position of the cutter 210 and low practicality of traditional devices by cooperating with the cutting adjustment mechanism and the waste collection mechanism.
[0030] The cutting adjustment mechanism can precisely adjust the 210mm spacing of the cutters to accommodate various sizes of bamboo leaves. The waste collection mechanism can efficiently collect trimming waste, which is convenient for subsequent use in the production of recycled fertilizer. The device has strong adaptability and meets the needs of large-scale bamboo leaf processing for multi-size adaptation, high efficiency and low consumption.
[0031] The fixed bracket 2 above the trimming table 1 provides a stable installation base for the cutting adjustment mechanism. The inner walls on both sides of the fixed bracket 2 are provided with symmetrically distributed sliding grooves 21. The inner walls of the sliding grooves 21 are slidably connected to guide sliders 22. The opposite ends of the two guide sliders 22 are fixedly connected to lifting blocks 23. This structure keeps the lifting blocks 23 stable when moving up and down, ensuring the accuracy of cutting.
[0032] The lower end of the lifting block 23 is provided with a mounting groove 24. The inner walls of both sides of the mounting groove 24 are rotatably connected to a bidirectional lead screw 25 through bearings. The outer side of the bidirectional lead screw 25 is fixedly sleeved with a worm gear 26. A servo motor 27 is fixedly installed on the front side of the lifting block 23. The output shaft of the servo motor 27 is fixedly installed with a worm gear 28 through a coupling. One end of the worm gear 28 passes through and extends into the interior of the mounting groove 24, and its outer surface meshes with the tooth surface of the worm gear 26.
[0033] With the servo motor 27 driving the worm 28 to rotate and meshing with the worm wheel 26, the bidirectional lead screw 25 rotates. The symmetrically distributed threaded blocks 29 connected to its external threads slide along the inner wall of the mounting groove 24. The lower end of the threaded blocks 29 is fixedly connected to the cutter 210, thereby precisely adjusting the spacing of the cutter 210 to adapt to different specifications of bamboo leaves and meet the needs of various zongzi sizes.
[0034] The front and back of the lifting block 23 are fixedly connected with symmetrically distributed mounting plates 211. The inner wall of the mounting plate 211 is slidably connected with a slide rod 212. The upper end of the slide rod 212 is fixedly connected with a limiting block 213, and the lower end is fixedly connected with a pressure plate 214. The upper end of the pressure plate 214 is fixedly connected with symmetrically distributed support springs 215. One end of the support spring 215 is fixedly connected to the lower end of the mounting plate 211.
[0035] When the piston rod of the servo electric cylinder 216 fixedly installed on the upper end of the fixed bracket 2 extends and drives the lifting block 23 to slide down, the pressure plate 214 first contacts the bamboo leaf, and the support spring 215 is compressed. The elastic buffer adapts to the natural bending shape of the bamboo leaf, so that the pressure plate 214 presses the bamboo leaf evenly, ensuring that the edges are even during trimming. At the same time, it provides stable support for cutting and improves the cutting quality. The servo electric cylinder 216 provides power for the movement of the lifting block 23, making the cutting process stable and efficient.
[0036] The trimming table 1 is equipped with a waste collection mechanism, including two symmetrically distributed collection channels 3 on the upper part of the trimming table 1, which provide a falling channel for trimming waste.
[0037] The inner walls on both sides of the trimming table 1 are fixedly connected with symmetrically distributed guide inclined plates 31, which can guide the waste to slide down smoothly. The front of the trimming table 1 is movably connected with a collection box 32, which makes it convenient for staff to take out the waste regularly. This waste can be used for fermentation to make recycled fertilizer, realizing resource recycling and conforming to the concept of green processing.
[0038] It should be noted that the electrical equipment mentioned above is all programmed and controlled using existing PLC controllers. Since this is a mature technology, it will not be described in detail.
[0039] The working process of this utility model:
[0040] Step 1: Place the bamboo leaf at the center of the trimming table 1. Based on the original length of the bamboo leaf to be processed, start the servo motor 27. The output shaft of the servo motor 27 drives the worm gear 28 to rotate through the coupling. The worm gear 28 meshes with the worm wheel 26, driving the bidirectional lead screw 25 to rotate. The symmetrical threaded block 29 on the outside of the bidirectional lead screw 25 slides along the inner wall of the mounting groove 24, driving the cutter 210 to move synchronously until the distance between the two cutters 210 matches the remaining length of the bamboo leaf. This process can quickly adapt to the trimming needs of bamboo leaves from different origins and different sizes of zongzi. Start the servo electric cylinder 216. The piston rod of the servo electric cylinder 216 extends, driving the lifting block 23 to slide down along the slide groove 21 and the guide slider 22. The pressure plate 214 first contacts the bamboo leaf, and the support spring 215 is compressed. The elastic buffer adapts to the natural curvature of the bamboo leaf, so that the pressure plate 214 presses the bamboo leaf evenly, ensuring that the edges of the bamboo leaf are flat and stable during trimming.
[0041] Step two: After the pressure plate 214 continues to press and position the bamboo leaves, the cutter 210 continues to slide down with the lifting block 23, cutting off the unusable parts at both ends of the bamboo leaves. The cutter 210 is made of sharp alloy material, and with the stable power of the servo electric cylinder 216, it can quickly cut the bamboo leaves, ensuring that the edges of the bamboo leaves are neat after trimming. After cutting, the servo motor 27 is started, driving the worm gear 28 to rotate clockwise. The bidirectional lead screw 25 drives the two cutters 210 to move in opposite directions. During the movement, the cutters 210 scrape the waste generated from the cutting table 1 onto the collection channel 3. The guide plate 31 in the collection channel 3 guides the waste to slide down, and finally collects it into the collection box 32. It can then be directly used for fermentation to make recycled fertilizer, realizing resource recycling.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
