It should be noted that the second pushing mechanism 60 may also be disposed below the second pressing mechanism 50 to push the previous bamboo strip in the reverse direction of the second pushing mechanism 60, but the transmission friction between the workpiece 500 and the transmission mechanism 20 needs to be overcome, so that the second pushing mechanism 60 is disposed below the first pressing mechanism 40 to push the bamboo strip more smoothly in the pushing direction, and the required pushing force is smaller.

Further, the second pushing mechanism 60 includes a third cylinder, a cylinder body of the third cylinder is installed on the frame 300, a piston rod of the third cylinder extends along the pushing direction, and the piston rod of the third cylinder is provided with a pushing plate, which extends out of the conveying surface 10 and pushes the workpiece 500. So, can be when carrying out the propelling movement of work piece 500, the propelling movement is pushed out along the propelling movement direction in the drive of stretching out of accessible third cylinder to propelling movement work piece 500 makes two bamboo strips be close to.

Further, the splicing mechanism 30 in this embodiment can be a high-frequency splicing machine in the prior art, and the glue solution between the two bamboo strips is instantly cured by the high-frequency heating device of the high-frequency splicing machine, so as to ensure that the water content of the spliced board is uniform and not deformed for a long time.

Further, the transmission mechanism 20 includes a first transmission roller 21 and a second transmission roller 22, the first transmission roller 21 and the second transmission roller 22 are arranged at intervals in the height direction of the rack 300, the transmission surface is provided with a transmission opening 12, the second transmission roller 22 extends out of the transmission opening 12 and is flush with the transmission surface 10, and a transmission interval is formed between the first transmission roller 21 and the second transmission roller 22. Therefore, when the bamboo strips are conveyed, the bamboo strips can be conveyed through the conveying interval between the first driving roller 21 and the second driving roller 22, the specific first driving roller 21 and the specific second driving roller 22 can be driven by the motor, and the rotating shaft of the motor can drive the first driving roller 21 and the second driving roller 22 to synchronously drive.

In addition, the surface of the second transmission roller 22 is exposed through the transmission opening 12 for transmission, so that the residue of glue solution on the surface of the second transmission roller in the transmission process of the bamboo strips can be reduced.

Further, transport mechanism 20 includes mount pad 23 and mounting bracket, can be with the top rigid coupling of mount pad 23 on frame 300, and the mounting bracket passes through elastic component 24 to be connected on mount pad 23, and first drive roller 21 pin joint is in the bottom of mounting bracket, so, first drive roller 21 accessible elastic component 24 exerts an elastic force on the bamboo strip surface, adjusts according to bamboo strip thickness and the condition in the transportation, and prevents to press bad bamboo strip in the transportation.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes should fall within the scope of the claims of the present invention.
