The panel conveyor further comprises at least one drive mechanism which is used for driving the first conveying belt and the second conveying belt to rotate synchronously in the same direction. The panel conveyor is convenient to adjust and can adapt to various production requirements.

The invention discloses an electronic keyboard rack with an adjustable height. The electronic keyboard rack comprises a movable box. The right side of the cavity of the movable box is provided with a forward and reverse motor. The output end of the forward and reverse motor is provided with a screw rod. The surface of the screw rod is provided with a movable screw block. The top of the screw block is provided with a first rotating shaft. The top of the first rotating shaft is provided with a movable rod. One end of the movable rod far from the first rotating shaft is provided with a second rotating shaft. The top of the second rotating shaft is provided with a connection rod. The bottoms of two sides of the connection rod are provided with sliding rods. Two sides of the cavity of the movable box are provided with sliding grooves matched with the sliding rods. The top of the connection rod goes through the movable box and extends to the top of the movable box. Through the mutual cooperation of the sliding rods, the sliding grooves, the screw rod, a controller, the connection rod, the first rotating shaft, the movable screw block, the forward and reverse motor, the movable rod and the second rotating rod, the height of the rack can be adjusted, and a music teacher is more comfortable in using an electronic keyboard.

The invention discloses a teaching instrument placement table. The teaching instrument placement table comprises a carrying box, wherein sliding plates are separately arranged on the tops and the bottoms of the left side and the right side of a cavity of the carrying box; a through hole is formed in the surface of each sliding plate; the top and the bottom of a cavity of each through hole are fixedly connected with limiting blocks separately; a push rod is inserted in the cavity of each through hole; a sliding track which is matched with the corresponding limiting block is arranged on the surface of each push rod; the top of each push rod penetrates through the carrying box and extends to the top of the carrying box; a carrying plate is arranged on the tops of the push rods; cylinders areseparately arranged on two sides of the top of the cavity of the carrying box; an output end of each cylinder is fixedly connected with a movable plate; and the surface of each movable plate is movably connected with the carrying box through a rotating shaft. By cooperation of the sliding plates, the cylinders, teeth, the sliding tracks, the push rods, the carrying plate, half teeth, the rotatingshaft, the movable plates, the limiting blocks and the through holes, the height of the placement table is adjusted, and thus, a user can feel comfortable when using a teaching instrument.

The invention discloses a car seat. The car seat includes a seat body and a graphene electric heating film for supplying heat to the seat body. The graphene electric heating film includes a first insulating protection layer, a graphene heating layer and a second heating layer. Insulation protective layer, and the conductor that is used to energize the graphene heating layer, the graphene electrothermal film also includes the thermal storage slow-release layer positioned between the first insulating protective layer and the graphene heating layer; wherein, the thermal storage slow-release layer consists of Made of thermal storage slow-release slurry, the thermal storage slow-release slurry contains thermal storage filler and the first resin, and the thermal conductivity of the thermal storage filler is 15‑50 W•m ‑1 • K ‑1 The car seat of the present invention can gradually heat up at a constant speed during use and slowly cool down after power failure, and can also make the temperature everywhere more uniform, avoiding the rapid rise in seat temperature caused by excessive heating and cooling in the prior art And the uncomfortable situation of the human body caused by excessive cooling.

The invention provides a microwave dryer. The microwave dryer comprises a machine body, a door body assembly, a rotating drum, a plurality of electric devices, a cooling air duct, a baking air duct and a fan device, wherein the cooling air duct comprises a cooling air inlet duct and a cooling air outlet duct which communicate with each other, and the electric devices are arranged in the cooling air duct; the baking air duct comprises a baking air inlet duct, a baking air outlet duct and a communicating air duct. According to the microwave dryer provided by the invention, the microwave dryer comprises the baking air duct and the cooling air duct, air outside the microwave dryer is sucked into the two air ducts by the fan device, the electric devices are arranged in the cooling air duct, and wind in the cooling air duct is used for cooling the electric devices, so that the probability that the temperature of the electric devices is too high is lowered, and then, the service lives of the electric devices are prolonged; air in the baking air duct is introduced into a baking chamber by the baking air duct, and water vapor in the baking chamber is taken out of the baking chamber and is discharged from the machine body, so that matters to be baked in the rotating drum are baked.

The invention discloses a mahogany plate painting device with good stability, which comprises a fixed base, a longitudinal drive mechanism is fixedly connected to both sides of the top of the fixed base, and a support column is slidably connected to the top of the longitudinal drive mechanism, and the two support columns are adjacent to each other. One side of the horizontal column is fixedly connected with a horizontal column, the surface of the horizontal column is slidably connected with a longitudinal driving mechanism, and the bottom of the longitudinal driving mechanism is fixedly connected with a painting mechanism. The present invention achieves the goal of using the seat, the movable block, the fixed column, the first support block, the threaded rod, the sliding sleeve, the connecting rod, the second support block, the fixed block, the worm wheel, the worm screw, the rotating rod and the sliding block. The mahogany plate maintains a stable effect during painting, which solves the problem of poor stability of the traditional mahogany plate spraying device in the process of spraying mahogany plate, and can keep the mahogany plate stationary during the painting process, thereby making the spray paint more uniform and greatly improving The quality of the spray paint is suitable for promotional use.
