4results about How to "Less prone to positional deviation" patented technology

This utility model discloses a trimming and cutting device for particleboard production, including a U-shaped bottom hollow frame, sponge rollers rotatably mounted at the front and rear positions inside the U-shaped bottom hollow frame via bearing seats, a drive shaft rotatably mounted on one inner wall of the U-shaped bottom hollow frame, and an external spline shaft rotatably mounted on the inner wall of the U-shaped bottom hollow frame below the drive shaft. A left cutting disc is fixed to one end of the external spline shaft near the inner wall of the U-shaped bottom hollow frame. A three-gear speed-increasing transmission structure is installed between the drive shaft and the external spline shaft. This utility model controls the positions of the L-shaped shaft carrier, T-shaped hollow bushing, internal spline shaft, and right cutting disc via a control panel and an X-axis lead screw electric module. After adjustment, the motor transmits power to the external spline shaft and internal spline shaft, causing the left and right cutting discs to rotate synchronously. The operator manually pushes the particleboard until the left and right cutting discs synchronously trim the edges of the particleboard.

The utility model relates to the technical field of photoetching, and particularly discloses a mask plate which comprises a glass plate and a film, the glass plate can be arranged on the mask frame; mounting grooves are formed in the glass plates; the film is embedded in the mounting groove, and the film is detachably connected with the glass plate; the film is provided with a graphic area and a non-graphic area, and the non-graphic area is arranged on the periphery of the graphic area in a surrounding mode. According to the utility model, the film can be positioned through the mounting grooves so as to ensure that the position of the film on the glass plate is fixed, so that when the film is replaced so as to overlay a plurality of layers of patterns, a plurality of films can be accurately aligned, and position deviation is not easy to occur, thereby avoiding low manufacturing precision of products, and meanwhile, improving the production efficiency. The non-graphic area of the film is in contact with the groove wall of the mounting groove, and the graphic area of the film is spaced from the groove wall of the mounting groove, so that the influence of the groove wall of the mounting groove on transfer of graphic information of the graphic area is avoided.

The application relates to a roadbed reinforcing structure for municipal roads, which comprises a geogrid for laying on the surface of the roadbed, the geogrid is provided with a gap slot arranged in sequence and at intervals; and a blocking seat arranged on one side of the geogrid, the side of the blocking seat away from the geogrid is provided with a lifting plate arranged in the lifting direction of the lifting plate, the blocking seat is screw-connected with an adjusting rod arranged along the lifting direction of the lifting plate, and the adjusting rod is used for driving the lifting plate to lift; the blocking seat is provided with a slot for the geogrid to pass through, the lifting plate is provided with a plurality of plug-in columns arranged in sequence and at intervals, and the plug-in columns are used for respectively penetrating into the corresponding gap slots. The application has the effects of reducing the additional workload during the laying of the geogrid, improving the laying efficiency of the geogrid, and ensuring the stability of the geogrid.

The utility model discloses an automatic feeding device for anchor chain ring bar shearing, which relates to the technical field of automatic feeding for bar shearing and comprises a hydraulic shearing machine, a shearing knife, a first conveyor, a second conveyor, a material receiving frame, a mounting frame, a driving motor, an overturning disc and a material receiving vehicle. A first conveyor is arranged on one side of the hydraulic shearing machine, and a second conveyor is arranged on the other side of the hydraulic shearing machine. According to the automatic feeding device for anchor chain ring bar shearing, when a baffle moves, a material guiding rod and a connecting block can be driven to move, when the baffle moves to the position above a mounting frame, the connecting block can move to the outer side of a fixing block, when a rotating shaft rotates, a first gear can be driven to rotate, and the material guiding rod and the connecting block can be driven to rotate; when the bars move on the first conveyor and the second conveyor, the moving positions of the bars can be limited through the limiting plates, so that the bars are not prone to position deviation in the moving process.
