The invention discloses an online detecting device for the thickness of a medium density fiberboard and relates to the technical field of detection. The online detecting device comprises a measuring mechanism installed on a fixing transverse frame, an upper guide plate and a lower guide plate, wherein through grooves are formed in the upper guide plate and the lower guide plate. One end of the upper guide plate is hinged to one side of the fixing transverse frame. The other end of the upper guide plate is connected with the measuring mechanism through a spring. The lower guide plate and the upper guide plate form a channel, wherein the front portion of the channel is wide, and the rear portion of the channel is narrow. A movable supporting wheel is arranged below the through groove of the lower guide plate. The measuring mechanism comprises a main shaft installed on a main shaft bearing in a box. One end of the main shaft extends out of the box and is connected with a support provided with idler wheels. The other end of the main shaft is connected with a slide ruler locating plate. The other end of the slide ruler locating plate is connected with a slide ruler fixing strip. The other end of the slide ruler fixing strip is connected with the main shaft, an induction shaft and an air cylinder through a middle connecting plate. The induction shaft is installed on a supporting bearing in the box. The upper end of the induction shaft is provided with a measuring magnetic head. The online detecting device can solve the problems that the measuring device is prone to being damaged, and the measuring stability and the measuring precision are influenced.
Description
technical field [0001] The invention relates to the technical field of wood-based panel manufacturing, in particular to a device for on-line detection of the thickness of medium fiber boards. Background technique [0002] In the MDF manufacturing process, the detection of the thickness of the raw board is to implement a dynamic thickness quality inspection of the products produced by the press by a thickness detection device installed on the MDF production line. The thickness detection device of the prior art includes a cylinder The connected lifting mechanism, the telescopic main shaft on the lifting mechanism is sleeved on a fixed sleeve, and the main shaft end is connected with a contact wheel. Because the main shaft and the fixed sleeve are simply inserted into this device, the friction force is large, and the lifting mechanism and the cylinder The connection part is relatively thin and easy to deform, so the thickness detection device is not stable, the main shaft and t...
