The invention relates to the technical field of carbon fiber spinning composite material production, and discloses a special production device for a carbon fiber spinning composite material, the special production device comprises a pre-oxidation furnace and a carbonization furnace, the pre-oxidation furnace is located on the horizontal left side of the carbonization furnace, and an unwinding roller is installed on the horizontal left side of the pre-oxidation furnace; a plurality of groups of polyacrylonitrile tows on the unwinding roller penetrate through the inner rotary drum seat to enter an oxidation chamber of the pre-oxidation furnace; and an inlet and an outlet are respectively formed in the middle positions of the left end surface and the right end surface of the carbonization furnace. According to the special production equipment for the carbon fiber spinning composite material, the pressure wheel on the anti-shrinkage structure makes contact with the lower end face of the polyacrylonitrile tow, the tension spring sequentially acts on the pressure wheel, the polyacrylonitrile tow is expanded, and therefore the shrinkage amount of the polyacrylonitrile tow is counteracted; meanwhile, the air outlet short pipes are evenly distributed on the two sides of the anti-shrinkage structure, direct air blown upwards directly acts on the lower end face of the polyacrylonitrile tow, and stretching and expansion of the linear polyacrylonitrile tow are assisted.

The utility model relates to a water anion health-care machine control system and a health-care machine, which are characterized in that on the basis of a control system circuit formed by a power supply module, a main control board, a complete machine switch, a conveying water pump, a conveying fan and a water anion generation module as main circuit components, the water anion generation module is newly designed; the Pi-type filter is adopted to filter residual voltage fluctuation interference in power supply voltage supplied by the power supply module to the water anion generation module, and the isolation power supply is adopted to isolate input and output of the water anion generation module, so that static electricity, interference signals and pulses generated by the anion generator are effectively isolated. The front-end control circuit is prevented from being influenced by static electricity, crosstalk and radiation interference at the rear end, and finally static charges in the circuit are absorbed by the static charge suppression elimination network and then are discharged to the ground end, so that the static charges of the water negative ion generation module are eliminated, and the effect of effectively suppressing or eliminating static electricity generation of the water negative ion health care machine is achieved.

The utility model discloses a surface cleaning device is used in organic silicon release film processing, including bottom plate, lower dust roller, upper dust roller and ion fan, the upper side of bottom plate is provided with riser seat, the upper rotation is connected with five number conveyer roller in riser, one side of five number conveyer roller is provided with winding roller. The utility model discloses through the mutual cooperation of upper dust roller and lower dust roller and the purging effect of ion fan, the complete cleaning of organic silicon release film surface is jointly ensured, and this multilevel cleaning mode can effectively remove the dust, electrostatic and other impurities on the surface of material, reduce impurity residue, improve the purity and processing quality of product, and the ion fan sends ion wind to the upper air outlet and lower air outlet through the air duct, carries out all -round electrostatic neutralization treatment to the organic silicon release film, and this design can effectively remove the static charge on the surface of material, prevents the adsorption, adhesion and other problems caused by static electricity, improves the stability of product and controllability in processing.
