The vacuumizing assembly is arranged on the protective cover and communicates with the inner side of the protective cover, and a sealing rubber strip is arranged at the bottom of the protective cover along the circumferential edge side. According to the utility model, glue can be cured in a vacuum state, so that the surface of the glue is smooth, dust and water vapor are not easy to adsorb, the operation reliability of the laser is improved, and the service life of the laser is prolonged.

The utility model discloses a superfine ground calcium carbonate discharge collecting device which comprises a collecting table and a feeding frame, the collecting table is located on one side of the lower portion of the feeding frame, and a supporting cylinder is installed in the middle of the top of the collecting table. According to the superfine heavy calcium carbonate discharging and packaging device, due to the fact that the adjusting disc is adopted, when superfine heavy calcium carbonate is discharged and packaged, a worker can sequentially fix a plurality of sets of packaging bags in the sealing grooves in the bottoms of the corresponding installing discs; therefore, after a set of packaging bags are collected, the rest of unused packaging bags can be moved to the feeding pipe through rotation of the adjusting disc, the collected packaging bags can be moved to the position away from the feeding pipe, it is guaranteed that feeding and discharging operation can be synchronously carried out, time consumed for replacement between steps is shortened, and the working efficiency is improved. And the overall operation efficiency can be effectively improved, more coherent operation can be conveniently achieved, the overall using effect is improved, and the beneficial effect of being high in operation efficiency is achieved.

The invention relates to an automobile motor shell deep drawing, trimming and stamping forming device which comprises an upper die and a lower die, the lower die is provided with a stamping base and a material supporting part used for supporting material belts, the feeding side and the discharging side of the material supporting part are each provided with a material belt stabilizing mechanism, and each material belt stabilizing mechanism comprises a clamping assembly and a driving assembly; the clamping assembly comprises at least one pair of oppositely-arranged clamping pieces, each clamping piece is provided with a fixed part and a movable part, and the movable parts can be controlled by the driving assembly to do opening and closing movement relative to the fixed parts so as to clamp or release the suspension sections of the material belts. The technical problem that the initial conditions for materials to flow into a female die are inconsistent due to the fact that a suspension section of a material belt vibrates up and down or drifts transversely in actual production of existing automobile motor shell stamping forming equipment is solved.

The utility model discloses a cement troweling device for civil engineering construction, which comprises a cement troweling machine, the cement troweling machine comprises a rack and a troweling plate arranged at the bottom of the rack, a driving motor for driving the troweling plate to rotate is arranged on the rack, a handheld push handle is arranged on the rack, an annular protective frame is sleeved on the periphery of the troweling plate, and the troweling plate is arranged on the outer side of the annular protective frame. A driving assembly for driving the annular protection frame to move up and down relative to the trowelling plate is arranged on the rack, and after the driving assembly drives the annular protection frame to move downwards and make contact with the ground, the trowelling plate is lifted to be separated from the ground. The annular protective frame provides protection for the manufacturing process, and operation safety is guaranteed. After cement surface operation is completed, the driving assembly drives the movable annular protection frame to move downwards to make contact with the ground, so that the troweling plate is lifted to be separated from the ground, and even if mistaken starting exists, the troweling plate can only idle and cannot be damaged.

This application provides a pointing remote controller, a display device, and a cursor positioning method. The pointing remote controller can acquire ultra-wideband data measured by a first ultra-wideband device and a second ultra-wideband device, as well as motion data of the pointing remote controller measured by an inertial measurement unit. Based on the ultra-wideband data and motion data, target parameters are calculated. Based on the motion data, the motion state of the pointing remote controller is determined. Based on the anchor point update mode corresponding to the motion state, the anchor point parameters corresponding to the target parameters are updated so that the anchor point parameters approach the target parameters. Based on the updated anchor point parameters, the cursor position is calculated and sent to the display device so that the display device moves the cursor according to the cursor position. By combining ultra-wideband data and motion data, and based on the anchor point update algorithm, a fast and smooth cursor response effect is achieved while ensuring tracking accuracy.

This utility model discloses an automatic selvage tension adjustment device, relating to the field of textile machinery technology. It includes: a machine housing with a base fixedly mounted on it; a tension roller rotatably connected to the base, the side of which is provided with several protrusions for inserting into the selvage; a support mechanism mounted on the base, which ensures that the selvage and the protrusions are always in contact; and a power mechanism mounted on the machine housing, which drives the tension roller to rotate. This utility model actively adjusts the tension of the selvage portion through a combination of electromechanical methods, thereby ensuring the smooth operation of the selvage folding device, enabling the selvage folding device to smoothly hook the yarn in, maintaining a smooth surface on the woven fabric, and improving product quality.
