[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown, the present invention provides an automated bamboo cutting and conveying device with adjustable cutting length: it includes a main frame 1 and a secondary frame 2. A cutting mechanism 3 is provided on the top of the main frame 1, and a cutting clearance slot 4 is provided on the top of the main frame 1 corresponding to the position of the cutting mechanism 3. Clamping mechanisms 5 are provided on the top of the main frame 1 and on both sides of the cutting clearance slot 4. A belt conveyor 6 for conveying bamboo segments to be cut is also provided on the top of the main frame 1. A detection mechanism 7 for detecting the length of bamboo segments is provided on the secondary frame 2.

[0026] The cutting mechanism 3 includes an electric push rod 301 and a hinged arm 302 hinged to the main frame 1. The telescopic end of the electric push rod 301 is hinged to the end of the hinged arm 302 away from the main frame 1, and a cutting machine 303 is fixedly installed on the hinged arm 302. The cutting mechanism 3 is used to cut bamboo.

[0027] The clamping mechanism 5 includes a fixed clamping plate 501 and an electric push rod 502 fixedly installed on the top of the main frame 1. A pressure sensor 503 is fixedly connected to the telescopic end of the electric push rod 502. A movable clamping plate 504 is fixedly connected to the other side of the pressure sensor 503. The fixed clamping plate 501 and the movable clamping plate 504 are located on both sides of the belt conveyor 6. With the setting of the two sets of clamping mechanisms 5, the two sides of the bamboo cutting point can be clamped and fixed, improving the stability of the bamboo cutting point, preventing the bamboo from shifting during the cutting process, and improving the flatness of the cut surface and the accuracy of the fixed-length cutting.

[0028] Several anti-deviation limit rollers 10 are rotatably connected to the top of the main frame 1 and to the front and rear sides of the belt conveyor 6. The anti-deviation limit rollers 10 can limit the bamboo and prevent the bamboo from deviating from the belt conveyor 6 during the conveying process.

[0029] A gantry frame 11 is fixedly installed on the top of the main frame 1. An electric push rod 12 is fixedly installed on the top of the gantry frame 11. A pressure sensor 13 is fixedly connected to the telescopic end of the electric push rod 12. A U-shaped frame 14 is fixedly connected to the bottom of the pressure sensor 13. A pressure roller 15 is rotatably connected inside the U-shaped frame 14. The electric push rod 12 is activated by the control panel 9 to extend downwards, causing the pressure roller 15 to move downwards. When the pressure roller 15 moves down to abut against the upper surface of the bamboo, the pressure sensor 13 monitors the contact force of the pressure roller 15 against the bamboo. When the preset pressure value is reached, the electric push rod 12 stops extending. During the bamboo conveying process, since the thickness of the bamboo is different at both ends, the pressure sensor 13 monitors the pressure value and transmits the monitored data to the programmable logic controller 8. This enables the pressure roller 15 to adjust the pressure of the bamboo during the conveying process in real time, so that the pressure of the pressure roller 15 on the bamboo is always kept within the preset value range, avoiding excessive or insufficient pressure on the bamboo.

[0030] The main frame 1 is equipped with a programmable logic controller 8, and a control panel 9 is provided on the top of the main frame 1. The programmable logic controller 8 and the control panel 9 are electrically connected to other electrical components of this application.

[0031] The detection mechanism 7 includes a servo motor 701 fixedly installed on one side of the sub-frame 2. The output end of the servo motor 701 is fixedly connected to a threaded rod 702. A threaded block 703 is threadedly connected to the outer surface of the threaded rod 702. Two guide rods 704 are movably inserted inside the threaded block 703. The two guide rods 704 are fixedly installed inside the sub-frame 2 and located on both sides of the threaded rod 702. A U-shaped frame 705 is fixedly connected to the bottom of the threaded block 703. An infrared transmitter 706 and an infrared receiver 707 are respectively provided on the front and back of the inner wall of the U-shaped frame. The infrared transmitter 706 and the infrared receiver 707 are positioned opposite each other. The infrared receiver 707 is electrically connected to the programmable logic controller 8.

[0032] Working principle: When bamboo needs to be cut into segments, the positions of the infrared transmitter 706 and infrared receiver 707 are first adjusted according to the required bamboo segment length. The distance between the infrared transmitter 706 and infrared receiver 707 and the cutting machine 303 is the length of the subsequent bamboo segment. The servo motor 701 is started through the control panel 9. The output end of the servo motor 701 rotates, driving the threaded rod 702 to rotate. Under the limiting action of the guide rod 704 on the threaded block 703, the threaded block 703 moves left or right along the axis of the threaded rod 702. Then, through the U-shaped frame 705, the infrared transmitter 706 and infrared receiver 707 move left or right, thereby adjusting the distance between the infrared receiver 707 and infrared transmitter 706 and the cutting machine 303, so as to adjust the length of the subsequent bamboo segment.

[0033] After the bamboo segments are cut to the correct length, the workers place the bamboo segments above the belt conveyor 6 and use the anti-deviation limit roller 10 to limit the bamboo segments, preventing them from deviating from the belt conveyor 6 during transport. The electric push rod 12 is activated via the control panel 9 to extend downwards, causing the pressure roller 15 to move downwards. When the pressure roller 15 moves down to contact the upper surface of the bamboo, the pressure sensor 13 monitors the contact force between the pressure roller 15 and the bamboo. When the preset pressure value is reached, the electric push rod 12 stops extending. During the bamboo transport process, since the bamboo segments are of different thicknesses at the ends, the pressure sensor 13 monitors the pressure value and transmits the monitored data to the programmable logic controller 8. This allows the pressure roller 15 to adjust the pressure on the bamboo in real time, ensuring that the pressure on the bamboo is always within the preset range and preventing the pressure on the bamboo from being too high or too low.

[0034] Subsequently, the belt conveyor 6 is started via control panel 9 to transport the bamboo. The bamboo moves towards one side of the detection mechanism 7. When one end of the bamboo moves between the infrared transmitter 706 and the infrared receiver 707, the bamboo blocks the infrared rays emitted by the infrared transmitter 706, preventing the infrared receiver 707 from receiving the infrared signal. The data is then transmitted to the programmable logic controller 8, which shuts down the belt conveyor 6. At this point, the distance between the cutter 303 and the infrared receiver 707 is the required cutting length of the bamboo. Simultaneously, the programmable logic controller 8 activates the electric push rod 502 to extend it, causing the movable clamping plate 504 to move towards the fixed clamping plate 50. The bamboo is moved to one side, thereby using the cooperation of the movable clamping plate 504 and the fixed clamping plate 501 to clamp and fix the bamboo. The two clamping mechanisms 5 are located on both sides of the bamboo cutting area, thereby clamping and fixing the bamboo on both sides of the cutting area, improving the stability of the bamboo cutting area, preventing the bamboo from shifting during the cutting process, improving the flatness of the cut surface and the accuracy of the fixed length cutting segment. Furthermore, through the setting of the pressure sensor 503, the clamping force of the movable clamping plate 504 on the bamboo can be monitored, so that the movable clamping plate 504 in the two clamping mechanisms 5 can adaptively maintain an appropriate clamping force according to the thickness of the bamboo at different positions, avoiding the clamping force of the movable clamping plate 504 on the bamboo being too large or too small.

[0035] After the clamping mechanism 5 clamps and fixes the bamboo, the controller starts the electric push rod 301 and the cutting machine 303. The electric push rod 301 extends and pushes the running cutting machine 303 through the hinged arm 302 to cut the bamboo into sections. The cut bamboo falls due to its own gravity, removing the obstruction of infrared light. At this time, the infrared receiver 707 can receive the infrared light emitted by the infrared transmitter 706 and transmit the data to the programmable logic controller 8. The programmable logic controller 8 then starts the belt conveyor 6 again to transport the bamboo, so as to realize the automated continuous fixed-length cutting of bamboo.

[0036] Example 2: As shown in the attached document Figure 5 As shown, this embodiment is basically the same as the previous embodiment, except that the detection mechanism 7 includes a vision detection module 708 fixedly installed on the top of the inner wall of the sub-frame 2. The vision detection module 708 uses an industrial camera and is electrically connected to the programmable logic controller 8.

[0037] First, the required length of the bamboo segments is input into the programmable logic controller 8. During the process of conveying and cutting the bamboo segments by the belt conveyor 6, the length of the bamboo segments conveyed to the cutting machine 303 away from the belt conveyor 6 is measured by the vision detection module 708. When the preset length is reached, the data is transmitted to the programmable logic controller 8, and then the cutting mechanism 3 cuts the bamboo segments to the desired length. This process is highly automated, saves time and effort, and replaces the traditional manual control of the bamboo segment length, making the size of the bamboo segments cut to the desired length more accurate.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
