The utility model discloses a kind of viscosity detection devices for woodworking glue production, including base, stand and controller, the upper surface of the base is fixedly installed with stand, the surface of the stand is equipped with the controller that can move up and down, the rear end side of the controller is installed with locking knob, the lower end of the controller is installed with motor, the output end of the motor is fixedly installed with rotor, the side surface of the motor is installed with protection frame.The utility model relates to a kind of viscosity detection devices for woodworking glue production, when the rotor needs to be disassembled, pull down protection frame, when protection frame drops, slide sleeve will be driven to drop, until the positioning rod of protection frame is withdrawn from the positioning groove of motor, in this process, spring will be compressed by the slide sleeve that is moved down, finally overturn protection frame and loosen the external force that pull down protection frame, at this time, there is greater working space when the rotor is disassembled, and it is not affected by the fixed protection frame.

This utility model discloses a bonding device for mixed eucalyptus and poplar laminated timber, including a base, a clamping mechanism, a cleaning and gluing mechanism, a gripping mechanism, and a conveying mechanism mounted on the base. When two pieces of eucalyptus and poplar laminated timber fall onto the worktable, the hydraulic cylinder is activated to move the support plate downwards, and the gripping cylinder is activated to adjust the angle of the suction cup. At the same time, the suction cup picks up the upper piece of timber. The electric push rod is activated to adjust the height of the cleaning and gluing mechanism by moving the slide rail. Then, the motor for driving the rotation of the drive spur gear is activated. The meshing of the drive spur gear and the rack drives the housing to move. The bottom of the upper piece of timber and the top of the lower piece of timber are cleaned by two cleaning plates and a dust suction plate. The gluing roller is pressed against the top of the lower piece of timber to roll and apply glue. Then, the hydraulic cylinder is activated again to press the upper piece of timber down, gluing the two pieces of timber together, which facilitates a more secure bonding of the timber.

This invention belongs to the field of building restoration technology, specifically a method for restoring a wooden Manchurian window in a historical building. The method includes the following steps: preparing the necessary tools and materials; protectively removing the wooden Manchurian window as a whole; repairing the wooden Manchurian window; removing paint from the wooden Manchurian window sash; cleaning the surface of the wooden Manchurian window; applying two coats of preservative and two coats of insect repellent to the wood surface; repairing any defects in the appearance of the wooden Manchurian window; sealing the window structure before painting; painting the surface of the window structure; restoring the window structure; and installing the wooden Manchurian window. By using small steel nails and wood glue for fixing during the window structure restoration process, the window structure can be restored to its original appearance according to the original mortise and tenon joint design, better preserving its original historical features, improving the restoration quality and service life of the Manchurian window in the historical building, and addressing the problems of significant color differences between the old and new windows and unsatisfactory restoration results caused by large-scale demolition and reconstruction in traditional techniques.
