This invention provides a nested, zoned, controlled vacuum insert for film-coated injection molds. A first cavity is provided on the core-side main insert, and an external vacuum insert is disposed within the first cavity. A first vacuum gap, communicating with the cavity, is formed between the outer wall of the external vacuum insert and the inner wall of the first cavity. A first air passage is provided on the external vacuum insert, communicating with the first vacuum gap to form an outer air passage. A second cavity is provided on the external vacuum insert, and an internal vacuum insert is disposed within the second cavity. A second vacuum gap, communicating with the cavity, is formed between the outer wall of the internal vacuum insert and the inner wall of the second cavity. A second air passage is provided on the internal vacuum insert, communicating with the second vacuum gap to form an inner air passage. A main air passage, communicating with an external vacuum device, is provided on the insert body. The first and second air passages are connected to the main air passage. The overall design of this invention is simple, with a reasonable distribution of adsorption force, and also incorporates the characteristics of flexible production.

This invention provides a laser welding device for prefabricated building components, belonging to the field of welding technology. It solves the problem that neither high-power laser welding equipment nor low-power handheld laser welding machines can meet the welding needs of construction sites. This laser welding device for prefabricated building components includes a mobile welding mechanism comprising a tracked walking assembly and a welding assembly. The tracked walking assembly includes a chassis and two tracks. Multiple driven wheels are installed inside the chassis. Two first rotary motors are fixed at one end of the chassis. The output shafts of the first rotary motors are connected to a reducer, and a drive wheel is fixed to the output shaft of the reducer. The two tracks are connected to the two drive wheels and the multiple driven wheels. Multiple permanent magnets are uniformly fixed to the outer surface of the tracks. The welding assembly includes a laser welder, which includes a laser collimating lens group and a two-dimensional scanning galvanometer arranged sequentially along the laser walking path. This invention has the advantages of flexible deployment, rapid assembly and disassembly, and intelligent ability to handle typical assembly conditions on construction sites.

The utility model discloses an integrated packing machine unpacking device, which relates to the technical field of packing machine unpacking, and comprises a support plate, the left side edge of the upper end of the support plate is fixedly connected with a left side plate, the right side edge of the upper end of the support plate is fixedly connected with a right side plate, and the upper ends of the left side plate and the right side plate are fixedly connected with a transverse plate. A first sliding groove is formed in the right side of the lower end of the transverse plate, a first rectangular groove is formed in the left side of the lower end of the transverse plate, a one-way threaded rod is rotationally connected into the first rectangular groove, a second electric telescopic rod drives an adjusting assembly to move, and a second motor drives a two-way threaded rod to rotate. The two-way threaded rod rotates to drive the two second moving blocks to rotate, the position distance of the suction cups can be adjusted, the two suction cups can be adjusted according to cartons of different sizes, it can be ensured that the suction cups can be effectively adsorbed to the surfaces of the cartons, and enough adsorption force is provided.
