Intermittent conveying mechanism for wood fiber board drying device

Abstract

The invention discloses an intermittent conveying mechanism for a wood fiber board drying device. The mechanism comprises a discharge cavity and a transfer pulley, the left end and the right end of the transfer pulley rotationally sleeve a first rotating shaft and a second rotating shaft respectively, a driving motor is fixedly installed on the side wall of the rear side of the middle of an innercavity of the discharge cavity through a fixing base, a transmission rod is perpendicularly connected to the driving motor through a power shaft, a sleeve is rotationally hinged to the tip of the transmission rod, an inner cavity of the sleeve slidably sleeves an adjustment rod, a telescopic rod is fixedly welded to the side wall of the bottom of the adjustment rod, the left end face of a T-shapedsliding block is fixedly welded to the right end face of the telescopic rod, a limiting column is fixedly welded to the left side of the front end face of the T-shaped sliding block, and an operationrod is rotationally hinged to the right side of the front end face of the T-shaped sliding block. Accordingly, rotation of the transfer pulley is controlled intermittently and conveniently, the drying device has enough time to dry wood fiber boards conveniently, and simpleness and practicability are achieved.

Description

technical field [0001] The invention relates to the technical field of application of wood fiber boards, in particular to an intermittent transmission mechanism for a wood fiber board drying device. Background technique [0002] Wood fiberboard, also known as density board, is a wood-based panel made of wood fiber or other vegetable fiber and applied with urea-formaldehyde resin or other suitable adhesives. Adhesives and additives can be applied during the manufacturing process. Fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, not easy to crack, etc., and has a wide range of uses. Dry production of fiberboard needs to be dried before forming. Fiber drying can use two pipeline airflow drying methods: the first-stage drying method has a temperature of 250 to 350 ° C and the time is 5 to 7 seconds; the second-stage drying method has a first-stage temperature of 150 to 180°C, the moisture content drops to 20%, the second sta...

Problems solved by technology

Dry production of fiberboard needs to be dried before forming. Fiber drying can use two pipeline airflow drying methods: the first-stage drying method has a temperature of 250 to 350 ° C and the time is 5 to 7 seconds; the second-stage drying method has a first-stage temperature of 150 to 180°C, the moisture content drops to 20%, the second stage temperature is 140 to 110°C, the moisture content drops to 6 to 8%, and the total time of the two-stage drying is about 12 seconds. The existing structure is complex and cannot meet the existing requirements. production and processing needs, so here we design and produce a kind of gap transmission mechanism for wood fiber board drying device, which is used for ease of use
