The utility model relates to a mirror surface polishing device, and belongs to the technical field of mirror surface polishing. The mirror surface polishing device comprises a polishing assembly and a connecting frame, the connecting frame is arranged on a supporting plate and located above a rotary disc, a guide frame is movably connected to one side of the connecting frame, a pressing disc is attached to one side of the guide frame and located on the upper surface of the connecting frame in a sliding mode, and a driving assembly is arranged on the supporting plate and used for pushing the guide frame; when the rotating disc rotates, the circumferences of the contact faces between the lower portions of the two sides of the pressing disc and the rotating disc are different, the pressing disc is driven to rotate in the rotating process of the rotating disc, rotating friction force is provided for the mirror face, and friction of the mirror face is uniform. The pressure plate is far away from and close to each other by taking the axis of the turntable as a base point, so that the contact area between the polishing cloth and the pressure plate is greatly increased, the use area of the polishing cloth is increased, and the waste of resources is reduced.

The application discloses a dry land corn seeding and film covering integrated machine and relates to the technical field of agricultural machinery. The machine comprises a rack, a processing mechanism arranged in the rack, a ploughing device, a ridger and a film covering frame fixedly installed on the inner wall of the rack, a seeding machine fixedly installed on the outer surface of the rack, a controller fixedly installed on the outer surface of the rack, a film discharging assembly arranged in the rack and a soil covering assembly arranged in the rack. The dry land corn seeding and film covering integrated machine is provided with a film discharging mechanism. When the device encounters hard soil blocks, instantaneous deceleration or temporary stop, the unwinding damping instantaneously increases, the roller shaft is difficult to rotate, the film is prevented from being continuously excessively pulled out, the film is prevented from being relaxed or accumulated due to the stop of the machine, the friction on the roller shaft is reduced when the device passes through the hard soil blocks or accelerates forward again, the film is allowed to be quickly pulled out, and the film is prevented from being torn due to excessive tension.

The utility model belongs to the technical field of cell phone shell processing, disclose a cell phone shell polishing device, including setting up in the motor, disk, stainless steel bar, polishing bucket in the casing, the output shaft of motor installs disk, sets up polishing bucket above disk, installs sound absorption board on the outer wall of polishing bucket, is provided with sound absorption hole on sound absorption board, installs the damping foot pad of shock absorption of casing bottom surface, sets up the polishing convex on the inner wall of polishing bucket, the inner wall of polishing bucket sprays lubricating layer, sets up gland on the top edge of polishing bucket, sets up sealing groove on the bottom surface of gland, sets up sealing strip in sealing groove, sets up sealing concave on sealing strip, sealing concave holds the top edge of polishing bucket, sets up air hole on the gland, sets up stainless steel bar in polishing bucket. The utility model effectively reduces the noise, and the structure is relatively simple, and the polishing operation is convenient.

The application relates to a fire hose wear resistance detection equipment and a detection method in the technical field of fire-fighting equipment detection, which comprises a case, a center frame fixedly installed at the middle of the inner wall of the case, a polishing mechanism rotationally arranged on the inner wall of the center frame, a rotating mechanism arranged on the center frame and used for driving the polishing mechanism to rotate, a first cap and a second cap, a fire hose body passing through the polishing mechanism arranged between the first cap and the second cap, and a fixing piece arranged at one end of the first cap and one end of the second cap and used for sealing the fire hose body. The fourfold guarantee effectively eliminates the gap between the fire hose and the friction component generated by the negative pressure adsorption mode of the prior art, ensures that the wear simulation is highly consistent with the actual fire scene hose dragging wear state, greatly improves the accuracy and reliability of the detection result, and meets the accurate requirement of fire hose quality detection.
