The utility model discloses a wire rod feeding mechanism of cold header, including frame subassembly and assembling on the frame subassembly, frame subassembly includes base and hinge joint installation base front end and wrap the protective cover of feeding subassembly outside, feeding subassembly includes the fixed plate that is fixed mounting base top, and the fixed plate is fixed mounting base top. The front end of the fixing plate is respectively and rotatably provided with two pressing wheels which are symmetrically distributed, the front end of the fixing plate is rotatably provided with a traction wheel which is located at the bottoms of the two pressing wheels, and the pressing wheels extend into grooves of the traction wheel in an annular protrusion shape. According to the wire feeding mechanism of the cold header, the situation that wires slip during conveying can be avoided, meanwhile, through flexible supporting of the movable base, the situation that the surfaces of the wires are sunken due to strong extrusion of the wires can be avoided, the wires can be kept in a good appearance state, and the production quality of products is effectively improved.

The invention relates to a sealing strip EPDM (Ethylene-Propylene-Diene Monomer) rubber sheet and rubber cement dual-purpose butt joint mold which comprises cold mold pressing molds and hot mold heating molds, the cold mold pressing molds are symmetrically arranged, and the two symmetrical hot mold heating molds are arranged between the cold mold pressing molds; according to the method, the phenomena of part appearance bruising, coating scalding and cracking caused by a hot mold are improved, the appearance state of a joint is improved, and the problem of technological limitation of an old mold is solved.

The utility model relates to the technical field of decoration panels, and discloses a moisture-proof decoration panel which comprises a panel body, a fireproof plate fixedly installed on the rear side face of the panel body, a waterproof film fixedly installed on the rear side face of the fireproof plate, a bottom plate fixedly installed on the rear side face of the waterproof film, and a base fixedly installed on the rear side face of the bottom plate. A limiting sliding groove is formed in the outer side face of the panel body, and a decorative side plate is slidably installed in the limiting sliding groove. According to the utility model, the plurality of waterproof films can be bonded with the panel main body by using the waterproof glue layer, and the invasion of moisture and moisture can be effectively avoided; the oily protective film not only can effectively prevent water and other harmful substances from intruding into the panel main body from the front side, but also can provide good weather resistance and water resistance, so that the panel main body can keep a good appearance state even under severe environmental conditions, and the overall service life and the overall attractiveness of the device are improved.

This utility model discloses a smart watch case with a snap-fit ​​structure, including a watch case base. A bottom shell is fixedly installed at the bottom of the watch case base. Fastening bolts are slidably connected to the four sides of the inner side of the bottom shell. Buttons are fixedly installed at the four corners of the watch case base. A transparent screen is fixedly installed in the center of the top of the watch case base. A locking block is snapped at the four corners of the top of the watch case base. A protective film is fixedly connected to the top of the four locking blocks. Through the locking blocks and the protective film, a protective film can be applied to the transparent screen, which can build a practical protective barrier for the transparent screen. It can effectively resist the scratches, bumps and wear that are unavoidable in daily use, prevent the transparent screen from leaving marks due to friction from hard objects such as keys and tabletops, and maintain the original smooth texture of the transparent screen. At the same time, the protective film can isolate the direct corrosion of stains such as sweat, oil, and dust, and reduce the oxidation, discoloration or staining of the transparent screen that is difficult to clean.

The invention relates to the technical field of composite materials, and discloses an ultrathin carbon fiber prepreg and a production process thereof.The ultrathin carbon fiber prepreg is composed of unidirectional reinforced carbon fibers and matrix resin, the unidirectional reinforced carbon fibers are spread through a high-precision yarn spreading device, so that the fiber surface density is smaller than or equal to 20 g, the fibers are evenly distributed, and the thickness of the matrix resin is larger than or equal to 20 mm; the fiber surface density fluctuation is less than or equal to 1g. The matrix resin is a thermosetting epoxy resin composition, and the gelation time of the epoxy resin composition at 120 DEG C is less than or equal to 25 minutes, so that the problems of non-uniform carbon fiber distribution, poor surface density precision, high apparent defect ratio, excessive fiber damage and the like in the prior art are solved.
