[0048] The working principle and process are as follows:

[0049] S1: Put an appropriate amount of bamboo strips on the first chain 203;

[0050] S2: The first motor 201 drives the first chain 203 to move, and the bamboo strips are sent to the front end of the first pushing plate 205;

[0051] S3: The first pushing mechanism 204 operates, driving the first pushing plate 205 to move upward, pushing the bamboo strips to the second chain 305 of the second feeding assembly 3, realizing the first separation of the bamboo strips;

[0052] S4: The third motor 401 drives the second chain 305 to move, and at the same time, the second pushing mechanism 302 starts to drive the second pushing plate 304 to move forward, sending the bamboo strips from the first feeding assembly 2 to the front end of the feeding hook 306;

[0053] S5: The second motor 301 drives the bent plate chain 307 to move, so that the feeding hook 306 mounted on the bent plate chain 307 starts to move, and the bamboo strips move upward under the driving of the feeding hook 306 and realize the second separation;

[0054] S6: During the movement of the feeding hook 306, the laminated detector 308 starts to detect the bamboo strips. If there are multiple bamboo strips overlapping, the kicking mechanism 309 works to kick the excess bamboo strips back to the second chain 305, ensuring that the bamboo strips are single to the third chain 402 of the buffering assembly 4;

[0055] S7: The third motor 401 drives the third chain 402 to move, sending the bamboo strips to the first buffering mechanism 403. The inductor 414 detects the material in place. If there is no bamboo strip at the front end of the second buffering mechanism 404, the first buffering mechanism 403 opens, and the bamboo strips are conveyed forward to the front end of the second buffering mechanism 404. During the conveying process, the bamboo strips pass through the distributing mechanism 406 and the limiting mechanism 410. If the bamboo strips are not separated in the second feeding assembly 3, there are multiple overlapping conditions, which will be pushed flat by the limiting plate 411 when passing through the limiting mechanism 410, forming multiple side-by-side states and being sent to the front end of the second buffering mechanism 404;

[0056] S8: If there is no bamboo strip at the front end of the third buffer mechanism 405, the distributing mechanism 406 drives the distributing plate 409 to lift up, and the second buffer mechanism 404 is opened, so that the single bamboo strip at the front end of the second buffer mechanism 404 is sent to the third buffer mechanism 405;

[0057] S9: When the inductor 414 detects that the bamboo strip reaches the front end of the third buffer mechanism 405, the camera 412 takes a picture to detect the front and back of the bamboo strip, and if the back is upward, the turning mechanism 407 is actuated to turn over the bamboo strip;

[0058] S10: If there is no bamboo strip at the front end of the blocking mechanism 408, the third buffer mechanism 405 is opened, and the bamboo strip continues to be sent to the front end of the blocking mechanism 408;

[0059] S11: When the inductor 414 detects that the bamboo strip reaches the front end of the blocking mechanism 408, the fourth motor 501 drives the conveying wheel 502 to rotate, and the conveying mechanism 504 is lifted up to lift the bamboo strip and press it to the conveying wheel 502, so as to convey the bamboo strip to the outlet guide groove 506;

[0060] S12: The bamboo strip is finally sent out of the device through the guidance of the outlet guide groove 506 and the limiting of the pressing mechanism 508;

[0061] S13: If the bamboo strip needs to be returned when the rear-end device connected with the feeding device is blocked, the first return mechanism 503 and the second return mechanism 505 are lifted up, and the bamboo strip can be smoothly returned through the first return mechanism 503 and the second return mechanism 505.

[0062] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
