An upper pressing plate pressing mechanism for a vertical shaft split sawing machine

Abstract

The invention discloses a upper pressing plate pressing mechanism for a vertical shaft bisection sawing machine. The mechanism comprises a bracket base plate and a clamping block fixed plate; one end of a movable shaft is fixedly connected with an upper pressing plate bracket; a thread hole is formed in the end surface of the upper pressing plate bracket; the clamping plate fixed block is fixed on the end surface of the upper pressing plate bracket by a locking screw A penetrating through a waist-shaped hole and in threaded connection with a thread hole in the upper pressing plate bracket; a lead screw support plate is provided with an adjusting lead screw for vertically penetrating through the lead screw support plate and in thread matching with the lead screw support plate; a sleeve clamping block is fixedly arranged on the end surface of the clamping block fixed plate; a lifting sleeve is inserted in a guide hole; a cylinder is fixedly arranged at the top of the lifting sleeve; a piston rod of the cylinder extends into the lifting sleeve, and is connected with a lifting shaft; and the bottom of the lifting shaft is connected with a connecting block and an upper pressing plate in sequence. The mechanism has the beneficial effects of: improvement of the bisection sawing quality, capability of adjusting the pressure of the cylinder, reliable pressure, and wide application range.

Description

Technical field [0001] The invention relates to the technical field of a vertical shaft split saw, in particular to an upper pressure plate pressing mechanism for a vertical shaft split saw machine. Background technique [0002] The vertical shaft splitting saw machine can split the wood board into multiple pieces of wood of equal thickness. The processing process is to feed the wood board between the multiple saw blades through the conveying mechanism. During the cutting and feeding process of the wood board, the wood board needs to be pressed to prevent The board jumps, so as to ensure that the thickness of the wood chips produced by the saw blade is consistent. The current pressing mechanism includes a pressing wheel and a spring. The spring is installed on the top of the pressing wheel. The pressing wheel presses on the top of the wood board under the action of the spring force. Although the wood can be pressed, the wood board and the pressing wheel are in line contact, and t...

Problems solved by technology

The current pressing mechanism comprises a pinch wheel and a spring. The spring is mounted on the top of the pinch wheel. The pinch wheel is pressed against the top of the plank under the action of the elastic force of the spring. Although the plank can be pressed, the plank and the pinch wheel are in line contact, and the pressure is not high. Stable, unreliable pressure, resulting in uneven thickness of wood chips after processing
