The application belongs to the technical field of laser cutting, and particularly relates to a steel structure profile laser cutting device, which comprises a workbench and a laser cutting head. An feeding assembly for clamping and conveying profiles is arranged on the workbench. The feeding assembly drives the profiles to move horizontally and rotate, so that the profiles move relatively with the laser cutting head. A work-type adaptive slag blocking mechanism is arranged on the workbench. The work-type adaptive slag blocking mechanism comprises a rectangular frame. The work-type adaptive slag blocking mechanism is used to fundamentally eliminate the situation that the laser beam needs to melt the solidified slag during subsequent cutting, so that the laser energy can directly and stably act on the profile surface, and the problems of rough section, slag hanging at the bottom and the like caused by slag scattering and surface state mutation are effectively avoided.

The application relates to the technical field of plate production equipment, and particularly discloses a vermiculite plate pressing production line. The production line comprises a pressing device, a conveying mechanism, a kiln car platform and a finished product trolley. The pressing device is provided with a fixed mold, a liftable movable mold and an upper pressing mold, and comprises a push plate assembly. The push plate assembly has an upper and lower open raw material box and can move along the upper surface of the movable mold. The raw material box supplies raw materials to the pressing cavity and simultaneously pushes the vermiculite plate away from the conveying mechanism after pressing, so that continuous operation of the "one-box dual-purpose" type is realized. The conveying mechanism is provided with a counting sensor and an angle-adjustable cleaning device for counting and cleaning the plate surface. The kiln car platform adopts a lifting push plate to automatically stack the plate on the multilayer supporting plate of the finished product trolley, and the finished product trolley is quickly positioned through a guide rail and a positioning wheel. The application realizes the full-process automation of vermiculite plate from pressing, demolding, conveying to automatic stacking, reduces manual intervention, and significantly improves the production efficiency and product consistency.

The utility model is suitable for film production and processing equipment technical field discloses the cooling and shaping device of PVC film, the cooling and shaping device of PVC film includes conveyer frame, cooling roll group, dust cover, air -inducing component, exhaust fan and lighting lamp. The utility model discloses dust cover is provided on the cooling roll group top, and the dust cover is linked with air -inducing component and exhaust fan, can block the workshop dust and fall on the PVC film surface in the cooling and shaping process, reduces its influence to product appearance, guarantees the film surface cleanliness, while, with the help of hanging lighting lamp in dust cover inner wall, can provide sufficient and angle suitable light, is convenient for production personnel to observe the defect of PVC film and checks production problem, to reduce unqualified product production, improves the production quality of PVC film.

The application discloses a feeding mechanism for microcrystalline tin ball processing and relates to the technical field of feeding equipment. The feeding mechanism comprises a base, a conveying mechanism is arranged on the base, the conveying mechanism comprises a transfer cylinder, the transfer cylinder is rotationally connected with the base, a plurality of through holes arranged in a ring shape and at equal intervals are formed in the transfer cylinder, a side plate is arranged on one side of the transfer cylinder, the side plate is in an arc shape and is fixedly connected with the base, the shortest distance between the upper end of the side plate and the transfer cylinder is equal to the radius of the outer opening end of the through hole, a plurality of felts arranged in an arc shape and at equal intervals are arranged on the side of the transfer cylinder close to the side plate, a plurality of metal springs are uniformly and fixedly arranged on the side of the felt away from the transfer cylinder, and the upper end of the metal spring is fixedly connected with the side plate. The feeding mechanism can screen and optimize tin balls during the feeding process, ensures that the output tin balls are high-quality tin balls with high size consistency, good surface cleanliness and strong internal structure integrity, effectively improves the feeding efficiency and the production efficiency, optimizes the screening step and ensures the yield of the tin balls.
