The utility model relates to the field of LED substrate processing discloses LED substrate heat conducting silicone grease fixture, including fixed frame, the fixed frame is located the top surface of base, the inside fixed installation board of fixed frame, the top surface of installation board is equipped with two fixed holes, the inside fixed metal round plate of fixed hole, the top surface of metal round plate is equipped with a plurality of smearing holes, the top surface of base is detachably provided with the placing plate, the top surface of placing plate is equipped with two containing grooves. In the utility model, scrape the heat conducting silicone grease on the metal round plate, the heat conducting silicone grease will be filled into the inside of smearing hole, through the limitation of smearing hole inside space, can accurately control the amount of heat conducting silicone grease every time smearing, thereby ensuring the consistency of smearing thickness.

The utility model relates to a coating mechanism, in particular to an arc-shaped surface contact coating mechanism, which comprises a rack, a feeding roller group used for conveying materials is arranged on the rack, a feeding path is formed on the feeding roller group, a coating station is arranged on the feeding path, the coating station is provided with a coating roller and a coating press roller, the coating roller and the coating press roller are arranged in a staggered mode on the feeding path, the coating press roller is located on the coating side of the coating roller, the coating roller and the coating press roller are staggered on the feeding path, and materials form a small-range arc-shaped contact face on the coating roller. And the coating on the surface of the coating roller is effectively, uniformly and firmly scraped and coated on the arc-shaped contact surface through the speed difference.

The utility model discloses an asphalt blade coating device for waterproof coiled material processing, and relates to the technical field of coiled material processing. The device comprises an operation table, a first adjusting mechanism is arranged on the operation table, the first adjusting mechanism comprises a [-shaped frame fixedly connected to the top of the operation table, a [-shaped plate is slidably connected to the inner wall of the [-shaped frame, and sliding grooves are formed in the inner wall of the front side and the inner wall of the rear side of the [-shaped plate. The inner walls of the two sliding grooves are fixedly connected with first sliding rods, and the two first sliding rods are slidably connected with sliding blocks. According to the utility model, the first adjusting mechanism can adapt to the fluctuation of the thickness of the coiled material, so that the coiled material can be well attached to the surface of the coiled material no matter how the thickness of the coiled material changes, asphalt is uniformly scraped and coated on the coiled material, the overall quality of the waterproof coiled material is improved, meanwhile, the impact force can be effectively buffered in the scrape coating process, and the service life of the coiled material is prolonged. The damage to the coiled material caused by excessive pressure is avoided, and the integrity and the physical property of the coiled material are ensured.

The application discloses a kind of roof waterproof protective layer crack auxiliary repair device and use method, to solve the problem that concrete roof protective layer crack is prone to secondary cracking after repair, device includes trolley platform, material cylinder, discharging mechanism and scraping mechanism, material cylinder is filled with concrete slurry, and support plate is driven to move down by push rod motor, and slurry is filled into crack by discharging cylinder, simultaneously, scraping mechanism moves down with slide plate, and scraping plate is unfolded by slide rail, and the filled slurry is scraped flat and even, to ensure uniform repair, after repair is completed, push rod motor resets, and device moves away;The device is simple to operate, can effectively prevent secondary cracking, and improve repair effect.
