The invention provides a post processing automatic production line for a road traffic mark board. A feeding device, a rack, a mark rod limiting device and a cloth wrapping device are included. The mark rod limiting device is arranged on the rack, the feeding end of the mark rod limiting device is located on one side of the output end of the feeding device, and the mark rod limiting device comprises a feeding conveying assembly and an elevating limiting assembly. The cloth wrapping device is arranged above the wrapping area and comprises a cloth conveying assembly, a clamping cloth pulling assembly and a wrapping assembly. In the synchronous process that the mark rod limiting device conveys a mark rod to the position below the cloth wrapping device, the clamping cloth pulling assembly is driven to pull and pave the cloth to the position above the mark rod, the two ends of the cloth are glued during cloth pulling and paving, then, the wrapping assembly sequentially wraps the two ends ofthe cloth to the surface of the mark rod, the manual wrapping manner is replaced, and the work efficiency is greatly improved; and the technical problems that in the prior art, time and labor are wasted during manual cloth winding, and the cloth winding efficiency is low are solved.

The invention discloses double-sided melting and impregnating equipment and a method for a continuous fiber-reinforcing adhesive tape. According to the equipment, a fiber pre-dispersion zone, a resin impregnation fiber zone and a fiber re-dispersion zone are arranged in a melting and impregnating equipment head; a pre-dispersion device is arranged in the pre-dispersion zone, and a double-sided distribution runner for distributing a resin melt is arranged in the resin impregnation fiber zone; in the fiber re-dispersion zone, a fiber channel is wavy, and re-dispersion devices are arranged on the upper side and the lower side of the fiber channel; an outlet at the tail end of the fiber channel is rectangular. The method comprises the following steps: firstly predispersing and preheating continuous long fibers, then entirely coating and impregnating through a double-sided distribution runner, and delivering out of the fiber channel after performing fiber redispersion treatment. According to the double-sided melting and impregnating equipment and the method, the impregnation effect of the resin melt to the continuous fiber in the adhesive tape can be balanced, the purposes of entire coating, permeation and impregnation can be achieved, the phenomenon that single-sided coating of the fibers is not tight can be avoided, long-time continuous stable production can be realized, and the output and quality of products can be both increased greatly.

The invention provides automatic adhesion equipment for the marking rod protection cloth of a road traffic denoter. The automatic adhesion equipment comprises a feeding device, a machine frame, a making rod limiting device and a cloth adhesion device, the marking rod limiting device is arranged on the machine frame, the feeding end of the marking rod limiting device is located on one side of the output end of the feeding device, the marking rod limiting device comprises a feeding transporting assembly, and a lifting limiting assembly, the cloth adhesion device is arranged above a coating areaand comprises a cloth conveying assembly, a clamping and cloth pulling assembly, and an adhesion assembly, the marking rod limiting device transports the marking rod below the cloth adhesion device sothat the cloth is flatly paved in a cloth clamping and paving area above the marking rod under the rotary clamping of the clamping and cloth pulling assembly, the glue coating at the two ends of thecloth is achieved while cloth pulling and paving are achieved, sequential cladding and adhesion of the two ends of the cloth on the surface of the marking rod by the adhesion assembly are achieved, the original manual cladding manner is replaced, and the problem of the low cloth winding efficiency in the prior art is solved.

The invention relates to a protective cover for a battery box of an electric vehicle. The electric vehicle at least has a frame unit and a body cover unit; A pair of left and right pedal tubes and right pedal tubes are arranged; the body cover unit has at least a pedal that can cover the left pedal tube and the right pedal tube; The battery box of the battery, the two sides of the battery box are provided with supporting shafts, the battery box is supported on the frame unit by the supporting shaft, the battery box has a battery access opening, and the battery access opening is provided with A protective cover that can cover the battery access opening; thereby enabling the battery to be stored stably in the battery box without moving with the inertial force of the front and rear, and to improve the dustproof performance of the battery box, thereby improving The use efficiency of the electric vehicle.

The invention discloses a passivation method for nickel hydrazine nitrate. The method includes: placing a coating agent in a solvent and conducting stirring to obtain a coating agent solution or dispersion liquid; weighing nickel hydrazine nitrate powder and adding the weighed powder into the coating agent solution or dispersion liquid slowly to obtain a mixed solution; putting the mixed solutionin a single-mouth flask, carrying out vacuum rotary distillation at certain temperature to remove the solvent until no fraction is distilled out, thus obtaining coated nickel hydrazine nitrate. The passivation way adopted by the invention has a wide application range and good coating effect, broadens the application scope of the coating agent, is convenient for screening of the coating agent, andis simple in operation and low in cost, thus being suitable for large-scale production.

The invention discloses a method for preparing a medical porous titanium or titanium alloy material coated with a tantalum coating on the surface. The method first adopts a 3D printing method to prepare a porous titanium skeleton or a porous titanium alloy skeleton, and then makes the porous titanium skeleton or porous titanium alloy After the skeleton is corroded, it is cleaned and dried, and then completely embedded in the ultrafine tantalum powder in the metal sheath, vacuum-sealed and then subjected to low-temperature diffusion sintering. Finally, the powder is removed after taking it out, and the medical porous titanium coated with tantalum coating is obtained. or titanium alloy material. The present invention coats tantalum on the surface of porous titanium skeleton or porous titanium alloy skeleton through powder embedding and low-temperature diffusion sintering to form a metallurgical bond, which greatly improves the bonding force between tantalum and the surface of porous titanium skeleton or porous titanium alloy skeleton, and solves the problem of The problem of poor bonding between the tantalum coating and the substrate overcomes the shortcomings of high cost and complicated procedures of the existing preparation methods.

An electromagnetic wave filter apparatus includes: a shield conductor; a shield aperture provided in the shield conductor; a plurality of strip conductors, each of which is connected to the shield conductor at both ends thereof, and which divide the shield conductor into a plurality of apertures; and a plurality of stub conductors provided at intervals on each of the strip conductors. Each of the stub conductors prevents a current with a predetermined frequency from flowing through a corresponding strip conductor due to an electromagnetic wave with the predetermined frequency passing through the electromagnetic wave filter apparatus. Thus, the electromagnetic wave filter apparatus passes the electromagnetic wave with the predetermined frequency without exerting a substantial influence on radiation of the electromagnetic wave with the predetermined frequency.
