The utility model relates to reinforcing mesh laying technical field, concretely relates to a bridge deck reinforcing mesh laying device, including the cushion block body, the downside of cushion block body is equipped with a plurality of support legs, still including the bearing plate and the clamping plate, the bearing plate is fixed at the cushion block body top, the top surface of bearing plate is uniformly recessed with four sliding slots, the sliding slot radial arrangement, every the sliding slot upside is equipped with the clamping plate, the clamping plate is the sector plate of the central angle 90 degrees, the tip of clamping plate is towards the central axis of bearing plate, the two radial sides of clamping plate are symmetrically equipped with V groove group, the V groove group is by two V grooves of up and down, and every V groove two ends respectively penetrate the arc surface and tip of clamping plate, and the slide rod slidingly connected in the corresponding sliding slot in the clamping plate bottom surface is equipped with in the sliding slot, is equipped with the limiting piece for limiting slide rod far away from the center of bearing plate. The utility model has solved the problem that the cushion block is difficult to limit and fix the longitudinal and transverse reinforcement of reinforcing mesh when using.

The present application relates to a kind of surface layer silicon source enrichment type ablation-resistant prepreg and its preparation method.The method first uses the inner impregnation solution containing boron phenolic resin and curing agent to impregnate quartz fiber fabric and discharge, and forms main body impregnation layer;Then the surface is treated with surface back wetting liquid containing boron phenolic resin and superfine silicon powder, and the maturation below gel temperature is obtained after discharge and lowing, to obtain ablation-resistant prepreg.The method can make superfine silicon powder more stably arranged in surface layer area, form boron-containing silicon vitrification protective structure in the ablation process, and improve the problem of local ablation deepening in edge area.

This utility model relates to the field of heat sealing technology, and more particularly to a high-strength heat sealing component for an automatic packaging machine based on PLC. It primarily addresses the problem that wrinkles occur at the PLC opening during batch heat sealing, leading to poor sealing and air leakage, resulting in low PLC packaging efficiency. The proposed technical solution includes a packaging platform, a pressing block on top of the packaging platform, a base fixedly connected to the bottom of the packaging platform, and a bonding wheel abutting the top of the packaging platform. This utility model uses the pressing block to press down on the packaging platform for heat sealing. The pressing down of the pressing block drives a threaded rod to rotate, which in turn drives a gear to rotate. This gear then drives the bonding wheel to roll and flatten the PLC opening placed on the packaging platform, thus pressing the pressing block against the packaging platform for heat sealing. This increases the flattening effect of the PLC opening and improves the PLC packaging effect.

This invention relates to the field of conveyor technology, specifically a belt conveyor with a material distribution function. It includes a conveyor body, a leveling component, a chili leaf removal component, a chili stirring component, an opening and closing component, and movable baffles. The leveling component is used to spread the chilies added to the feeding hopper evenly on the conveyor belt. The leveling component includes multiple rotatable stirring plates, each with a large chili leaf passage opening on its side. The chili leaf removal component is rotatably disposed within the feeding hopper. This invention effectively improves the working efficiency of the chili leaf removal component, thereby enhancing the quality and efficiency of the entire leveling and subsequent material distribution and sorting process. Furthermore, by removing most of the chili leaves, a certain spacing is maintained between the chilies, preventing them from piling up due to crowding during transport, allowing them to be arranged in an orderly manner, and avoiding them getting stuck in the gap between the leveling component and the conveyor belt.

This invention relates to the field of recycled pavement base paving equipment, and in particular to a recycled cement concrete pavement base material paving equipment. Addressing the problem in existing technologies where vibrating rods always move in a straight line, easily causing longitudinal concrete breakage, this invention provides a recycled cement concrete pavement base material paving equipment. It includes a rotatable vibrating cylinder that rotates when an automatic paver moves. Multiple detachable vibrating rods are mounted on the circumferential surface of the vibrating cylinder. During use, the vibrating cylinder rotates synchronously with the automatic paver, moving at the same speed. As the automatic paver moves, the vibrating cylinder rotates synchronously, allowing the vibrating rods to be inserted into the base material sequentially to vibrate it and then withdrawn as the cylinder rotates. This prevents the vibrating rods from moving within the base material and causing longitudinal concrete breakage.

The application provides an outer heat-proof load-bearing and inner heat-insulating integrated cover body and a preparation method thereof, and belongs to the technical field of load-bearing and heat-proof integrated composite materials. The cover body comprises an outermost heat-proof load-bearing layer, an innermost heat-insulating layer and an intermediate adhesive film layer. The heat-proof load-bearing layer is made of fiber reinforced benzoxazine resin, the heat-insulating layer is made of phosphazene rubber, silicone rubber or nitrile rubber, and the adhesive film layer is made of modified benzoxazine adhesive film. The application realizes co-curing of the outer heat-proof load-bearing layer and the inner heat-insulating layer, and solves the interface problem of the outer heat-proof load-bearing layer and the inner heat-insulating layer through preparation and coating of the modified benzoxazine adhesive film.
