Preferably, the carriage 32 comprises a first end 324 connected to the first driving device 33 and a second end 325 at the other end; the partition plate 323 is gradually inclined upward from the first end 324 to the second end 325; the second end 325 includes a closure plate 3251 that movably encloses the first and second receiving areas 321, 322. In practical implementation, the first driving device 33 includes a sprocket and a chain belt, the first end portion 324 is connected to the chain belt, the chain belt is driven by the sprocket to lift and drive the conveying frame 32 to lift, the first accommodating area 321 and the second accommodating area 322 can be opened or closed by the movably closed sealing plate 3251, and only one row of yarn bobbins can be replaced during one-time conveying of the conveying frame 32; the sealing plate 3251 is opened to place a new bobbin on the partition plate 323, the new bobbin rolls into the first accommodating area 321 in a smooth manner, and a plurality of new bobbins are loaded at the moment; at the same time, the old yarn package in the second receiving area 322 can be removed to empty the second receiving area 322; the efficiency of loading and unloading a yarn section of thick bamboo in the carriage 32 can be effectual improved, the time of loading and unloading a yarn section of thick bamboo is saved.

Preferably, the carriage 32 further includes a support plate 326 below the second receiving area 322; the support plate 326 has an extension 3261 extending toward the frame body; the extension 3261 is gradually inclined upward from the root to the end. In actual practice, the old bobbin is supported by the supporting plate 326; when the old bobbin on the loading and unloading unit 4 falls off on the extension part 3261 and rolls into the second accommodating area 322 along the extension part 3261, the old bobbin can be effectively prevented from falling off, the time for collecting the old bobbin is reduced, and the efficiency of the bobbin in the longer conveying frame 32 is improved.

Preferably, the rack main body 31 further includes a guide bar for guiding the carriage 32. In actual implementation, carry on spacingly through the guide bar to carriage 32, make carriage 32 along guide bar lift movement, carry on spacingly through the guide bar simultaneously and make carriage 32 to the clearance of first face 311 be less than the external diameter of old yarn section of thick bamboo, and then make the accurate second accommodation region 322 that falls into of old yarn section of thick bamboo ability.

The product form of the present invention is not limited to the embodiments and examples shown in the present application, and any suitable changes or modifications of the similar ideas should be made without departing from the patent scope of the present invention.
