The invention relates to the field of rice straw treatment equipment, in particular to complete equipment for harvesting, smashing and collecting rice field straw, the edges of beating pieces are edged, so that the beating pieces become real blades, cutting force can be reduced under the condition that it is guaranteed that straw can be cut off, and therefore the wall thickness of a knife roller body, a conveying roller body and a pressing roller body can be reduced, and the cutting efficiency is improved. The plate thickness of the casing can be reduced; each roller body is made of a seamless steel pipe, a hollow part is filled with light and adhesive filling materials such as polyurethane, the filled adhesive filling materials are light in weight and high in hardness and can play a role in supporting the roller bodies and dispersing stress, the machine shell is made of an alloy material, ribs are filled at the plate bodies of the machine shell, and the machine shell is made of an alloy material. In this way, the wall thickness of each roller body and the wall thickness of the machine shell can be further reduced, the weight of the whole machine is greatly reduced, and therefore the equipment can walk on a paddy field.

The invention discloses a BOPP film edge shaping device, which relates to the field of cutting technology; in order to solve the problem of smooth incision; specifically comprises a frame, the inner wall of the frame is respectively connected to an upper cutting roller through an upper cutting shaft, and is connected to a lower cutting roller matched with the upper cutting roller through a lower cutting shaft, a cutting knife is fixed to the outer wall of the end of the upper cutting roller, and a knife groove matched with the cutting knife is provided on the inner wall of the lower cutting roller; the inner side wall of the frame is connected to a winding roller 2 through a winding shaft 2. The invention provides a cutting knife and a heating coil, and on the basis of cutting with the cutting knife, the heating coil can heat the cutting knife by electromagnetic induction and Joule effect, so that the cutting knife is hot-cut, so that the film can be softened during hot cutting, and the cutting force required for cutting and separation can be reduced. At the same time, when the cutting force becomes smaller, the tensile stress on the film during separation can also be reduced, so as to ensure the flatness of the incision.

A kind of bionic disc cutter for stalk cutting and its design method belong to the technical field of agricultural machinery.The cutter includes cutter base body and multiple cutter teeth which are uniformly distributed along the circumference of the cutter base body in the same direction.The cutter teeth are arc teeth bent to one side, the outer profile curve of the cutter teeth is composed of smooth transition curve, and the side disc surface corresponding to the cutter base body is a plane, and the other side disc surface corresponding to the cutter base body is a curved surface with a cutter tooth surface profile curve composed of arc transition, and the cross section from the cutter tooth root to the cutter tooth tip gradually decreases.The present application significantly reduces the cutting force and cutting energy consumption, improves the cutting efficiency and prolongs the service life of the cutter.

The invention provides a positioning and clamping device and cutting system for a non-metal honeycomb core material. The positioning and clamping device comprises a foundation platform and a clamping mechanism used for clamping the non-metal honeycomb core material, and the clamping mechanism is detachably fixed to the foundation platform; the clamping mechanism comprises an upper elastic buffering cushion, a lower elastic buffering cushion and a plurality of clamping force adjusting assemblies. The upper elastic cushion pad and the lower elastic cushion pad are matched to clamp the non-metal honeycomb core material; the multiple clamping force adjusting assemblies are distributed on the inner side of the edge of the non-metal honeycomb core material in a surrounding mode and used for adjusting the clamping force between the upper elastic buffering cushion and the lower elastic buffering cushion. Multi-point positioning of the non-metal honeycomb core material is achieved through the multiple clamping force adjusting assemblies, and the positioning stability is effectively improved; and due to the arrangement of the upper elastic buffer cushion and the lower elastic buffer cushion, the effect of protecting the non-metal honeycomb core material is achieved, the cutting force at the high cutting speed can be effectively buffered, the stress concentration situation under high-speed cutting is avoided, and the cutting quality of the non-metal honeycomb core material under high-speed cutting is improved.

The invention relates to the technical field of cutting, in particular to radioactive ultra-thick nuclear graphite plate cutting equipment which comprises a drilling and cutting assembly and a cutting assembly, the drilling and cutting assembly comprises a conversion driving mechanism and a conversion shell rotationally arranged on the outer side of the conversion driving mechanism, and a drilling mechanism and a cutting mechanism are arranged at the upper end and the lower end of the conversion shell correspondingly; a dry ice pipeline is arranged at the bottom of the conversion driving mechanism; the anti-blocking assembly comprises a connecting mechanism movably connected with the dry ice pipeline. The method has the beneficial effects that an operator manually controls the mode of drilling first and then cutting, stress concentration in a material is reduced, the risk of crack formation is reduced, meanwhile, the needed cutting force is reduced, dry ice is used as a cooling medium, the problems of material deformation and thermal stress caused by high temperature are reduced, and the service life of the material is prolonged. In the cutting process, the diamond wires are adopted, and dry ice cooling is matched, so that fragments and dust generated in the cutting process can be remarkably reduced.

This utility model relates to the field of optocoupler technology, and in particular to an anti-interference optocoupler packaging structure. By placing the fifth pin completely inside the package, the creepage distance between the fifth pin and the adjacent high-voltage fourth and sixth pins is greatly increased. Under high-voltage conditions, the voltage difference between the fourth and sixth pins or the electric field generated by their voltage to ground must travel a longer distance through the interior of the package insulation material (such as epoxy resin) or along its outer surface to reach the fifth pin. This significantly increases the effective electrical insulation creepage distance and electrical clearance, thereby significantly improving the working stability and safety of the product. It solves the technical problem that the creepage distance between the fourth and sixth pins and the fifth pin in existing 6-pin optocouplers is too short, which makes the fifth pin and the circuit components mounted on its surface susceptible to interference or even leakage.
