Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the efficacy and purpose that can be achieved by this application.

[0022] In the field of industrial bamboo processing, bamboo material undergoes splitting and rough milling to produce rough-milled bamboo strips of a specified width and thickness. These strips often require fine milling to achieve smooth, precise dimensions. Traditionally, fine milling involves manually feeding the rough-milled strips one by one into a fine milling machine for finishing. However, this manual process is not only labor-intensive but also carries a high risk.

[0023] To address this problem, bamboo strip feeding equipment has been introduced. However, existing bamboo strip feeding equipment struggles to effectively identify and remove defective strips with broken edges when processing large quantities of strips. When these strips are indiscriminately fed into the milling machine's feed port, they can easily cause jams, leading to interruptions in milling operations and severely impacting the efficiency and continuity of the milling process.

[0024] Please refer to the attached Figure 1 To the attached Figure 6 As shown, an embodiment of the present invention provides an automatic feeding device for fine milling of bamboo strips, comprising a frame 10, a bamboo strip separation mechanism, a bamboo strip online detection mechanism, and a bamboo strip qualified product feeding mechanism 40; the bamboo strip separation mechanism is arranged on the frame 10, and is used to separate multiple bamboo strips one by one to realize the automatic separation of rough milling bamboo strips; the bamboo strip online detection mechanism includes a conveying mechanism 31, a detection mechanism and a kicking mechanism 33, the conveying mechanism 31 is arranged at the output end of the bamboo strip separation mechanism, and its conveying direction is along the length direction of the frame 10, and is used to convey the bamboo strips separated by the bamboo strip separation mechanism; the detection mechanism includes a first camera 321, a second camera 322 and a third camera 323, and the first camera 321 and the second camera 322 are respectively located on the conveying mechanism 31 and the third camera 323. 1 and on the left and right sides of the frame 10 in the width direction. The third camera 323 is located below the conveying mechanism 31 and in the middle of the frame 10 in the width direction. The kicking mechanism 33 is located at the end of the conveying mechanism 31. The qualified bamboo strip continuing delivery mechanism 40 is located on the side of the conveying mechanism 31 and its delivery direction is along the width direction of the frame 10. The first camera 321, the second camera 322, and the third camera 323 are used to identify whether the bamboo strips are defective during the conveying process. If the bamboo strips are defective, the kicking mechanism 33 can remove the defective bamboo strips from the qualified product flow. If the bamboo strips are not defective, the qualified bamboo strip continuing delivery mechanism 40 can deliver the qualified bamboo strips along the width direction of the frame 10 to the subsequent equipment. It should be further noted that the bamboo strips with defects include but are not limited to broken edges. The subsequent equipment can be, but is not limited to, a fine milling machine.

[0025] In the present invention, the automatic feeding equipment for fine milling of bamboo strips includes a frame 10, a bamboo strip separation mechanism, a bamboo strip online detection mechanism, and a bamboo strip qualified product continuous feeding mechanism 40; the bamboo strip separation mechanism is arranged on the frame 10, and is used to separate multiple bamboo strips one by one; the bamboo strip online detection mechanism includes a conveying mechanism 31, a detection mechanism and a kicking mechanism 33, the conveying mechanism 31 is arranged at the output end of the bamboo strip separation mechanism, and its conveying direction is along the length direction of the frame 10; the detection mechanism includes a first camera 321, a second camera 322 and a third camera 323, the first camera 321 and the second camera 322 are respectively located above the conveying mechanism 31 and on the left and right sides of the width direction of the frame 10, and the third camera 323 is located on the left and right sides of the width direction of the frame 10. Camera 323 is located below the conveyor mechanism 31, midway across the width of the frame 10. The kicking mechanism 33 is located at the end of the conveyor mechanism 31. The qualified bamboo strip feeding mechanism 40 is located to the side of the conveyor mechanism 31, and its feeding direction is along the width of the frame 10. The first camera 321, the second camera 322, and the third camera 323 are used to identify whether the bamboo strips are defective during conveyance. If the bamboo strips are defective, the kicking mechanism 33 removes them from the qualified product stream. If the bamboo strips are not defective, the qualified bamboo strip feeding mechanism 40 feeds qualified bamboo strips along the width of the frame 10 to subsequent equipment. This design, by integrating the bamboo strip separation mechanism, the bamboo strip online inspection mechanism, and the qualified bamboo strip feeding mechanism 40, achieves automated separation of rough-milled bamboo strips. After separation, broken bamboo strips can be identified and automatically removed in real time, effectively preventing broken bamboo strips from clogging the fine milling machine. This reduces production interruptions caused by clogging and improves overall fine milling efficiency and production line continuity. Compared with the traditional process of manually feeding the rough-milled bamboo strips into the fine milling machine for fine processing one by one, this design greatly reduces labor costs, realizes the automation and continuous feeding of bamboo strips, and improves production safety.

[0026] Existing bamboo strip feeding equipment often encounters the problem of tail end crossover when processing large quantities of bamboo strips. During the feeding process, the tail ends of the inserted bamboo strips easily cross, making it difficult for the equipment to automatically separate the strips. Manual intervention is required, significantly reducing the efficiency of automatic bamboo strip feeding. Furthermore, due to differences in length, thickness, and curvature between different bamboo strips, the strips can easily nest together in layers, or in layers, during feeding. This can easily cause the feeding process to jam, leading to a direct shutdown of the feeding equipment and further compromising the efficiency of automatic bamboo strip feeding.

[0027] Therefore, in some optional embodiments, the bamboo strip separation mechanism includes a primary feeding assembly and a secondary feeding assembly; wherein the primary feeding assembly includes a primary horizontal feeding device 211 and a primary vertical feeding device 212, wherein the conveying direction of the primary horizontal feeding device 211 is along the length direction of the frame 10, the conveying direction of the primary vertical feeding device 212 is along the height direction of the frame 10, and the primary vertical feeding device 212 is arranged at the discharge end of the primary horizontal feeding device 211; and the secondary feeding assembly includes a secondary horizontal feeding device 221 and a secondary vertical feeding device 222, wherein the conveying direction of the secondary horizontal feeding device 221 is along the length direction of the frame 10, the conveying direction of the secondary vertical feeding device 222 is along the height direction of the frame 10, the secondary horizontal feeding device 221 is arranged at the discharge end of the primary vertical feeding device 212, and the secondary vertical feeding device 222 is arranged at the discharge end of the secondary horizontal feeding device 221. This effectively solves the problems of tail end crossing and bamboo strip nesting, and improves the efficiency of automatic bamboo strip feeding. Improved separation and conveying mechanisms prevent the ends of bamboo strips from crossing, maintaining their individuality. Furthermore, an optimized feeding mechanism accommodates strips of varying lengths, thicknesses, and curvatures, preventing nesting of strips in layers. Combined with these improvements, this technology significantly enhances the automation and efficiency of the bamboo strip processing process.

[0028] The bamboo strip separation mechanism operates as follows: First, multiple bamboo strips are placed on the first-level horizontal feeder 211, which delivers them to its discharge end, where they are received by the first-level vertical feeder 212. Subsequently, the first-level vertical feeder 212 lifts the strips upward and delivers them to their discharge end, where they are received by the second-level horizontal feeder 221. This lifting and conveying process achieves the first separation of the strips. Next, the second-level horizontal feeder 221 delivers the strips delivered by the first-level vertical feeder 212 to its discharge end, where they are received by the second-level vertical feeder 222. Finally, the second-level vertical feeder 222 lifts the strips upward again and delivers them to their discharge end, where they are received by the conveying mechanism 31 of the online bamboo strip detection mechanism, achieving the second separation of the strips. This double separation process of the bamboo strip separation mechanism effectively and automatically achieves the separation of multiple bamboo strips. This process can separate crossed or nested bamboo strips, reducing the need for manual intervention and effectively avoiding jams in the feeding process and equipment downtime, thereby improving the efficiency of automatic bamboo strip feeding.

[0029] It should be further noted that because the third camera 323 is located below the conveyor mechanism 31 and in the middle of the width of the frame 10, with its lens facing upward, dust easily accumulates on the lens, thereby affecting the effective acquisition of image data. Therefore, in some optional embodiments, the online bamboo strip inspection mechanism also includes a blower 34, located above the third camera 323, for removing dust from the lens of the third camera 323. The provision of the blower 34 effectively solves the dust accumulation problem, ensuring that the lens of the third camera 323 remains clean, thereby ensuring the accuracy and validity of the image data.

[0030] Please see the attached Figure 7 As shown, in some optional embodiments, the conveying mechanism 31 includes a conveying chain 311, a first set of buffer devices 312, a material distributor 313, a second set of buffer devices 314, and a flipping device 315. The conveying chain 311 is wound around a sprocket, which is driven by a motor 318 to rotate the conveying chain 311, and the conveying chain 311 rotates to convey bamboo strips. The first set of buffer devices 312 are located on the left and right sides of the front end of the conveying chain 311; the material distributor 313 is located at the rear end of the first set of buffer devices 312; the second set of buffer devices 314 are located at the rear end of the material distributor 313 and on the left and right sides of the conveying chain 311; and the flipping device 315 is located at the rear end of the second set of buffer devices 314. The first set of buffer devices 312 is used to temporarily block the conveying of bamboo strips, causing them to remain at the front end of the first set of buffer devices. While the bamboo strips are at the front of the first buffering device, the first, second, and third cameras 321, 322, and 323 can identify defects and verify whether the strips are single. If the strips are not single, the separating device 313 is activated to further separate the strips, ensuring that they are delivered to the finishing mill in single pieces. The second set of buffering devices 314 can also temporarily block the delivery of the strips, allowing the first, second, and third cameras 321, 322, and 323 to determine whether the strips are facing upward. If the strips are facing upward, the flipping device 315 is activated to flip the strips to the required orientation, with the strips facing downward.

[0031] In some optional embodiments, both the first set of buffering devices 312 and the second set of buffering devices 314 utilize telescopic cylinder structures. The fixed end of the telescopic cylinder is mounted on the frame 10, while the telescopic end moves up and down to block and control the conveyance of the bamboo strips. Two first and two second sets of buffering devices 312 and 314 are installed on the left and right sides of the conveying mechanism 31, respectively, to ensure stability and accurate control of the bamboo strips during conveyance.

The kicking guide plate 332 is connected to the output end of the drive unit 331, and the drive unit 331 is capable of driving the kicking guide plate 332 to swing. The drive unit 331 may be, but is not limited to, a pneumatic cylinder or an electric push rod. Specifically, the kicking guide plate 332 is elongated, and the output end of the drive unit 331 is hingedly connected to the kicking guide plate 332. The hinge point is located at a non-central position along the length of the kicking guide plate 332. At one end of the hinge point, the kicking guide plate 332 forms a long section, and at the other end, a short section. When the drive unit 331 retracts and extends, the kicking guide plate 332 swings about the hinge point, thereby removing defective bamboo strips.

For details, please refer to the attached Figure 8 As shown, the upper feeding device 41 includes a power device 411, a sprocket 412, a transmission chain 413 and a first feeding wheel 414. The output end of the power device 411 is connected to the sprocket 412, and the sprocket 412 and the first feeding wheel 414 are connected by the transmission chain 413. The power device 411 can be but is not limited to the motor 318, and the first feeding wheel 414 is located below the motor 318; the lower feeding device 42 includes a lifting cylinder 421, a mounting bracket 422 and a second feeding wheel 423.
