Description

Technical Field

[0001] The utility model relates to the technical field of push plate devices, in particular to a continuous plate-jointing push plate device for a sand saw line. Background Art

[0002] The artificial board sanding saw line consists of a sanding line and a sawing line. The stack of boards to be sanded and sawed is carried by a hydraulic lift and stepped up to cooperate with the pusher to push the boards. In actual production, after each stack of boards is pushed, the hydraulic lift must first be lowered empty to receive the stack of boards delivered by the forklift roller table, and then it is lifted to the stepped position with a heavy load, and the pusher continues to push the boards. During the entire stacking process, the pusher stops pushing the boards. Due to the high installed capacity of the entire line, other single machines in the production line run at no load, which wastes time and electricity, reduces the production efficiency of the sanding line, and thus affects the production of the sawing line. Yes, the existing patent number is CN201520248000.3, which is an efficient artificial board pushing system. It discloses a method of switching between the first pusher and the second pusher. After the material on the first lifting platform is transported, the second pusher is continued to push the material. That is, the two groups of lifting platforms switch with each other and cooperate with the corresponding pushers to push the boards, which can always ensure the continuity of board feeding. A similar double-stack pushing device is used to achieve the continuity of board feeding. This method occupies a large area of ​​equipment, has a high cost of equipment, and has high repair and maintenance costs. Utility Model Content
