This utility model discloses a filter paperboard punching mechanism, relating to the field of filter paperboard processing technology. It includes a hydraulic punching main unit, with a punching worktable on the front side of the main unit. A lower punching die is fixedly connected to the upper front end of the worktable. A hydraulic telescopic rod is fixedly connected to the upper end of the main unit via a cantilever, positioned directly above the lower punching die. Through the use of elastic heating support pads and elastic pressure pads, the loose fiber structure of the filter paperboard is effectively prevented from being compacted, ensuring the air permeability and filtration efficiency of the filter paperboard. Simultaneously, the elastic heating support pads heat the filter paperboard when in contact with it, softening the fibers and preventing brittle breakage, thus improving the quality of the punching process. Furthermore, the elastic pressure pads further reduce the direct impact of the punching blade on the paperboard, resulting in a smoother punching edge, reducing burrs and fiber damage, and improving the overall quality of the product.

The adjusting structure is arranged, the hydraulic rod is used for pushing the sliding block to drive the adjusting plate to move, so that the supporting seat is supported, the height of the supporting seat is adjusted, the adjusting plate is rotationally connected with the supporting seat, the adjusting plate is prevented from being excessively abraded, and the supporting seat is more stable.

The utility model relates to the technical field of ladle overturning machines, and discloses an efficient hydraulic ladle overturning machine which comprises a base and further comprises a fixing column fixedly connected to the surface of the base, the top of the fixing column is connected with a connecting plate through a rotating shaft, and the connecting plate is fixedly connected to the bottom ends of the two sides of an overturning table. The bottom end of the overturning table is further connected with a hydraulic rod through a connecting shaft, and the output end of the hydraulic rod is connected with the overturning table through a connecting shaft. According to the turnover table, the stop lever is arranged on one side of the rotating shaft of the turnover table, so that limiting is achieved when the turnover table drives goods to turn over, the bottoms of the goods can be conveniently supported after the goods are turned over, meanwhile, due to the telescopic arrangement of the stop lever, the goods can be conveniently unloaded on the surface of the turnover table, adding of external facilities is avoided, and the turnover table is convenient to use. And the guide wheels are rotationally arranged in the stop levers, so that the contraction flexibility of the stop levers at the bottoms of the goods is ensured, and the vertical pressure of the goods on the surfaces of the stop levers is reduced.

The utility model belongs to the technical field of stock bins, and particularly discloses an automatic weighing stock bin which comprises a stock bin body, a cylindrical cavity is formed in the upper portion of the stock bin body, and a conical cavity is formed in the lower portion of the stock bin body. An annular connecting plate is arranged at the joint of the cylindrical cavity and the conical cavity, a support is arranged at the bottom of the annular connecting plate, a support is arranged at the bottom of the support, and the support is movably connected with the support. A weighing assembly is arranged in the support, a pressure sensor is arranged on the side wall of the support, the weighing assembly is used for supporting the support, and the weighing assembly extrudes the pressure sensor under the gravity action of the support; the pressure sensor is connected with an external controller, and the controller is used for obtaining parameters of the pressure sensor. According to the utility model, the pressure sensor is arranged on the side wall of the support, the support is movably connected with the bracket, and the weighing assembly extrudes the pressure sensor to obtain the weight of the stock bin, so that the vertical pressure of the bracket on the hydraulic sensor is reduced, and the service life of the pressure sensor is prolonged.

A heel protection device special for an advanced tumor patient comprises a bottom connecting sleeve, a left side connecting sleeve, a front side connecting sleeve and a rear side connecting sleeve. The bottom connecting sleeve, the left side connecting sleeve, the front side connecting sleeve and the rear side connecting sleeve are integrally formed to form the water cushion sleeve, water can be injected into the water injection cavity in the water cushion sleeve, and therefore the water cushion sleeve can effectively reduce the temperature of skin, reduce local metabolism and prevent pressure sores. Outer protrusions are evenly arranged on the inner sides of the bottom connecting sleeve, the left side connecting sleeve, the front side connecting sleeve and the rear side connecting sleeve, so that the water cushion sleeve is uneven, a gap exists between the water cushion sleeve and the skin making contact with the water cushion sleeve, air circulation is facilitated, the skin of the pressed portion is kept dry, the protruding positions of bones can be effectively erected, and the skin can be effectively protected by means of flowability and deformability of water. The support has good compliance, deformability, bearing capacity and pressure relief capacity, the pressure of a pressed part is relieved, and meanwhile, the vertical pressure, friction force and shear force of the skin and a bed at the bone protrusion position are buffered.
