The utility model discloses an insulation board surface scratch-proof transportation tray structure. The thermal insulation board surface scratch-proof transportation tray structure comprises a tray and a cloth liner installed on the tray. The tray comprises a bottom plate which is located at the lowermost end and plays a supporting role, a plurality of vertical rods are arranged on the bottom plate, a plurality of steering rods used for supporting the cloth liner are fixedly installed on the vertical rods, and a first rotating cylinder is rotationally installed at the upper ends of the vertical rods; the cloth liner is made of a flexible material and is used for being cushioned between the two adjacent heat preservation plates, a rotating shaft is arranged at the end of the cloth liner, and the rotating shaft is rotationally installed on the bottom plate; the extending direction of the cloth liner is changed through the steering rod. According to the thermal insulation board surface scratch-proof transportation tray structure, the effect of separating and protecting two adjacent thermal insulation boards is achieved by arranging the cloth liner, scratches and the like generated by mutual pressurization friction of the thermal insulation boards in the transportation process are reduced, and the transportation safety and condition of the thermal insulation boards are improved.

The utility model discloses a kind of waste treatment devices for packaging box production, belong to packaging box waste treatment technical field, its technical scheme main points include mounting bracket, pulverization box and screening box, the inner wall of mounting bracket is fixedly connected in screening box and pulverization box, the left side of pulverization box is fixedly connected with processing mechanism, the front side of screening box is fixedly connected with auxiliary mechanism;The processing mechanism includes motor, assembling rod, main gear, mounting rod, pinion, pulverization roller, fixed link, boss and screen, main gear and pinion are engaged by motor drive, drive two groups of pulverization roller relative rotation, can be quickly with packaging box waste material shearing, roll into uniform broken material, pulverization efficiency is high and effect is stable, utilize belt drive to make fixed link synchronous rotation, the boss on its surface continuously impact screen and produce vibration, can be separated according to granularity after pulverization Waste material, fine material is collected through screen by discharge hopper, coarse material remains to facilitate classification processing.

This utility model discloses a return spring coiling fixture to solve the problems of multiple processes and low efficiency in return spring coiling. The fixture consists of a mandrel, a bushing, and a sheet structure. The mandrel has a smooth surface and one end is a connecting end to a drive device. The bushing is fitted over the mandrel, with an inner diameter slightly larger than the outer diameter, and an auxiliary structure on its outer surface to guide the material coiling direction. The sheet structure is mounted on the bushing to assist in coiling and shaping. During coiling, one end of the spring material is fixed, and the drive device is activated to rotate the mandrel. The material advances in the gap between the mandrel and the bushing and is coiled under the action of the sheet structure. This fixture, through reasonable design and the coordinated operation of its components, enables rapid coiling of return springs, significantly shortening coiling time, improving production efficiency, and meeting the needs of large-scale production. It also reduces human error, ensuring consistent product quality. Furthermore, its simple structure and convenient operation reduce the technical requirements for operators and alleviate labor intensity.
