The invention relates to a glass assembly and a vehicle. The glass assembly comprises glass; the covering edge comprises a main body, a first tongue piece and a second tongue piece, the main body is connected to the edge side of the glass, the first tongue piece is arranged on the main body and used for extending towards the automobile body matching part, the second tongue piece is arranged on the inner side face of the first tongue piece, and the second tongue piece is used for abutting against the automobile body matching part so as to prevent the first tongue piece from being bent towards the inner side of the glass assembly. The second tongue piece can generate thrust towards the outside of the glass assembly on the first tongue piece, so that the first tongue piece is far away from the R angle of the vehicle body matching piece, and the edge curling phenomenon that the first tongue piece is bent towards the inner side of the glass assembly due to the fact that the first tongue piece is collided and interfered by the R angle of the vehicle body matching piece is avoided. Therefore, not only is the hemming problem of the first tongue piece well solved, but also the problems that the hemming needs to be corrected manually after installation, the adjustment operation is difficult, and time and labor are wasted are solved, it is guaranteed that the hemming phenomenon is not generated during one-time installation, and the installation quality and production efficiency of a glass assembly are improved.

The utility model relates to the field of paperboard processing, and discloses a slitting device for paperboard processing, which comprises a workbench, slitting equipment is arranged on the upper surface of the workbench, a rotating shaft is rotatably mounted between the front end and the rear end of the inner wall of the slitting equipment, and a driving motor is mounted at one end of the rotating shaft extending out of the slitting equipment; cutting blades are installed on the two side portions of the outer surface of the rotating shaft, supporting discs are welded to the positions, close to the two side portions of the cutting blades, of the outer surface of the rotating shaft, a containing groove is formed in one side of the outer surface of each supporting disc, an elastic sleeve gasket is arranged on the portion, located in the containing groove, of the outer surface of each supporting disc in a sleeving mode, and a supporting mechanism is further arranged in each supporting disc. According to the paperboard slitting device, the slitting position of a paperboard is pressed through the elastic sleeve gasket, so that the effect of conveniently limiting and supporting the paperboard in the cutting process is achieved, the regularity of the slitting position of the paperboard is improved, the problem of edge curling caused by the hollow interior of the paperboard in the slitting process is solved, and the attractiveness of the slit paperboard is improved.

The invention discloses a phase-controlled spray cone guide wet dust removal process and a dust removal device thereof, which relate to the technical field of wet dust removal, and include a phase-controlled spray washing tower, a cone guide mist removing tower and a limit pipe whose two ends are respectively fixedly plugged between the phase-controlled spray washing tower and the cone guide mist removing tower. The invention can arrange full-coverage spray in a multi-phase staggered manner through the cooperation of the phase-controlled spray washing tower and the cone guide mist removing tower to wash the dust and droplets in the dust-containing steam, and the secondary part of the flue gas with dust is pushed through the upper top arc of the guide cone to the tower wall end of the cone guide mist removing tower, thereby accelerating the flue gas flow rate, making the droplets, mist droplets and a small amount of dust collide with the tower wall and the cone top arc to form a gas-liquid separation and gas-dust separation flow field, which can further improve the dust removal effect, and the dust removal device can also recycle water, saving the use cost. In addition, the solidified impurities can be cut to facilitate the further purification and circulation of turbid water.

The application discloses a kind of automatically slitting inductance protection bearing tape preparation equipment and preparation method thereof, comprising: conveying table, heat pressing device, cutting device and cooling device are sequentially arranged in conveying table two sides from left to right;Including the following steps: S1, accurate positioning is carried out to bearing tape by positioning structure and position is corrected;S2, bearing tape is contacted with heater by positioning pressing plate and is pressed down, and the edge of bearing tape is softened;S3, the both sides of bearing tape are cut simultaneously by blade;S4, bearing tape is rapidly frozen and cooled by liquid nitrogen injection part, and then the bearing tape piece is blown to the blanking transmission part by air injection part, and the blanking of single bearing tape piece is completed.The application effectively solves the problem of curling caused by uneven stress distribution by combining heating treatment, arc cutting and air blowing blanking, improves production efficiency, improves product quality and stability, reduces manual operation and error, and reduces production cost.

The invention relates to the technical field of textile equipment, in particular to a multi-stage after-finishing device for knitted fabric. The multi-stage after-finishing device comprises a pair of double-opening extension threaded rollers, an infrared weft twill road detection device, two pairs of single-opening threaded rollers and an ironing and shaping assembly which are sequentially arranged in the motion direction of the knitted fabric at intervals. The driving assembly is used for driving the single thread roller to rotate and is electrically connected with the infrared weft twill road detection device; threads emitted from the middle section of the rolling shaft to the two ends are arranged on the surface of the double-opening extension threaded roller; and the thread directions of the two pairs of single thread rollers are opposite. According to the multi-stage after-finishing device for the knitted fabric, the functions of cloth cover extension, weft twill road detection, weft skew elimination, ironing and shaping and winding are integrated, and the after-finishing path of the knitted fabric is greatly shortened.
