The utility model discloses a nozzle cover of an air textured yarn processing machine. The nozzle cover comprises a fixing block and a stand column installed at one end of the fixing block. A mounting block is arranged at one end of the fixing block and arranged on one side of the stand column. An adjusting assembly is hinged to one end of the mounting block and comprises an adjusting block movably connected to one end of the mounting block, and a plug is connected to the side, close to the fixing block, of one end of the adjusting block in a matched mode; an air inlet is formed in the fixed block; a nozzle is arranged at one end of the air inlet; the rotating angle of the adjusting block is flexibly adjusted through the rotating shaft, so that the dislocation angle of the plug and the nozzle is accurately controlled, then the air inlet amount of the air inlet hole is accurately adjusted, the machining efficiency of the air textured yarn is improved, the plug is located over the nozzle, blown air is collided back, turbulent flow is formed in the nozzle, and the machining efficiency of the air textured yarn is improved. The hair feeling of the yarn is changed according to the size of the turbulent flow, and the hair feeling of the air-jet texturing yarn can be controlled according to the height of the plug.

This invention provides an active air intake grille, belonging to the field of automotive component technology, comprising: a grille body, the grille body having an arcuate structure; a flexible shaft, the flexible shaft being bent wholly or partially according to the arcuate shape of the grille body, and the flexible shaft being rotatably mounted on the grille body; a blade assembly, the blade assembly including at least two grille blades, each of the grille blades being arranged according to the arcuate shape of the grille body, each of the grille blades being connected to the flexible shaft, and the flexible shaft driving each of the grille blades to rotate when rotated; it also relates to an automobile, including an active air intake grille. The beneficial effect of this invention is that, based on setting the grille body as an arcuate structure, the flexible shaft can synchronously drive each grille blade arranged in an arcuate plane on the grille body to rotate, thereby achieving the purpose of non-linear transmission.

The utility model relates to laboratory powder spraying equipment capable of preventing static interference. The laboratory powder spraying equipment comprises a cabinet body and a small-dose powder outlet spray gun system, a powder feeding cavity, a middle cavity and a powder collecting cavity are formed in the cabinet body. Plastic plates are arranged on the top face, the left side face, the right side face and the bottom face of the powder feeding cavity. The small-dose powder discharge spray gun system comprises a fluidization cylinder, and the powder storage amount of the fluidization cylinder is 10-150 g. A powder outlet of the Venturi powder pump is connected with the spray gun; the powder adjusting mechanism is suitable for adjusting the concentration amount of the powder pumped out by the powder pumping pipe. According to the laboratory powder spraying equipment capable of preventing electrostatic interference, the plastic plate is arranged in the powder feeding cavity, so that electrostatic interference caused by electric conduction of metal plates on the periphery to electrostatic spraying is avoided, metal powder is close to spraying on a production line when a sample plate is sprayed in a laboratory, and the accurate powder spraying effect is achieved; and the quality inspection accuracy of a sample plate manufactured in a laboratory is ensured. On the premise of ensuring the accuracy, the equipment is very convenient to use and clean afterwards.
