In order to ensure the stable mechanical properties of the fiber board, it is necessary to detect the flexural strength of the fiber board after production. Most of the existing bending detection devices squeeze the fiber board through cylinders, and it is not easy to flexibly adjust the extrusion force according to the bending state during the detection process.

The disadvantage of this utility model is that this device uses a cylinder for extrusion, and it is not easy to adjust the extrusion force in real time according to the bending state during the detection process.

Therefore, squeezing the middle position of the fiberboard can achieve the bending of the fiberboard. The support frame installed on the base is used to install the pressing component and the measuring component. The pressing component can squeeze the fiberboard for bending strength detection. During the detection process, in order to ensure the stability of the pressing force, the clamping component installed on the support frame can fix the pressing position of the pressing component to ensure the stability of the pressing force. At the same time, the measuring component installed on the support frame can detect the bending degree of the fiberboard to facilitate observing the bending state of the fiberboard, so as to adjust the pressing component, achieving the purpose of manually adjusting the pressing force by observing the bending state.

Both ends of the bending block of the bending component are rotationally connected to the support plates on the base. The cross-sectional shape of the bending block is semi-circular. The rotating shafts I are installed at the centers of the bending blocks. The bending blocks can rotate around the rotating shafts I. The bending blocks on both sides rotate towards each other for bending detection of the fiberboard. A fixing plate that can move along the sliding groove is installed on the bending block. The fixing plate is L-shaped. When the L-shaped fixing plate moves towards the fiberboard, it can fix the fiberboard on the bending block. The two ends of the fiberboard are respectively fixed by the fixing plates on the bending blocks on both sides. Such a design facilitates the placement of the fiberboard.

One end of the clamping column is connected to the support plate, and the other end of the clamping column is placed in the guiding groove. In order to ensure the stability of the bending block during rotation, clamping columns are installed at both ends of the bending block. One end of the clamping column is placed in the guiding groove. The guiding groove is arc-shaped. Under the restriction of the clamping column, the clamping block can only rotate along the guiding groove. Such a design can improve the stability of the rotation process.

[0010] Preferably, the support frame includes a support column and a mounting plate.

The "work"-shaped lifting rod slides up and down in the lifting groove. An extrusion rod is installed at the lower end of the lifting rod for extruding the fiberboard. A rack is installed on one side of the lifting rod. The rack meshes with the gear installed between the rotating plates. The gear is fixed on the rotating plate through the shaft II. A handwheel is installed at one end of the shaft II. By rotating the handwheel, the gear rotates around the shaft II. Due to the meshing of the gear and the rack, the lifting rod is driven to lift and lower, thereby extruding the fiberboard. Such a design can extrude the fiberboard.

A ratchet wheel is installed on the shaft II. The ratchet wheel is provided with a plurality of ratchet grooves distributed in a circular pattern for fixing. The cooperation between the fixing rod and the ratchet grooves on the ratchet wheel fixes the gear. The existence of the spring can make one end of the fixing rod always contact the ratchet wheel.

In order to ensure that the inclination sensor is completely attached to the fiberboard, it is attached by lowering the adjusting rod. The adjusting rod is fixed by the fixing nuts on both sides of the mounting plate. The height of the adjusting rod is controlled by adjusting the positions of the two fixing nuts. Such a design is due to the attachment to the fiberboard.

[0013] The beneficial effects of the utility model are as follows: By observing the bending state and manually adjusting the extrusion pressure, it is convenient to place the fiberboard, which can improve the stability of the rotation process, can extrude the fiberboard, and can fix the rotation angle of the gear.
