The application belongs to the technical field of kitchen utensil manufacturing, and particularly relates to an integrated stove and a use method thereof. The integrated stove increases the precision of oil fume suction by respectively configuring two groups of stove tables with corresponding and specially-structured smoke collecting devices, and reduces energy consumption to a certain extent. The application also designs the structure and position of the supporting pipe bottom ring and the fixing assembly base, effectively avoids the outflow of oil fume from the gap between the supporting pipe and the first surface on the basis of ensuring the stable installation of the supporting pipe, and improves the installation sealing performance of the end part of the supporting pipe. In addition, the application also sets a smoke sensing device and a driving device matched with the smoke sensing device, so that the smoke collecting device can rotate around the central shaft of the supporting pipe under the driving of the driving device, and adjust the relative angle between the box body smoke guide opening and the pot above the stove table. Therefore, the integrated stove can realize the precise adsorption of oil fume.

This invention provides an automated packaging machine for finished wire products, relating to the field of wire packaging technology. It includes: an outer machine with an open top section; an inner lining frame fixedly installed inside the opening; a lower support fixedly installed on the front side of the inner lining frame; a lower support cylinder fixedly installed in the middle of the lower support; and a lower support plate fixedly installed at the telescopic end of the lower support cylinder; a lifting control frame fixedly installed on the front top section of the outer machine. This invention is adaptable to the overall packaging needs of various specifications of wire. Through the coordinated operation of the rolled plastic packaging film, the double heat-sealing strip of the heat sealer, and the cutting blade, the packaging film is precisely cut, and the first basic heat seal is completed simultaneously. This provides a complete packaging function for the wire throughout the entire process, ensuring a tight fit between the packaging film and the wire roller, and achieving continuous supply of packaging film without frequent individual packaging, facilitating subsequent sealing processes, and adapting to the needs of large-scale continuous operation.

This invention relates to the field of door frame technology, specifically an S-shaped door frame structure, comprising: a door frame; a sealing device disposed inside the door frame and extending to the surface of the door frame; wherein, the sealing device includes a side sealing mechanism longitudinally disposed on the surface of the door frame, a sealing adjustment mechanism disposed on one side of the side sealing mechanism, a top sealing mechanism disposed between the two side sealing mechanisms, and an anti-pinch mechanism disposed on the side of the side sealing mechanism away from the sealing adjustment mechanism, the anti-pinch mechanism extending to the outside of the door frame; the side sealing mechanism includes a hinge, a push-acting assembly, and a sealing assembly; by providing the side sealing mechanism and the top sealing mechanism, the contact area between the door panel and the door frame can be sealed under the action of the side sealing mechanism and the top sealing mechanism, reducing wear caused by opening and closing the door panel, thereby ensuring the sealing effect of the gaps.

This utility model relates to the field of gear pump technology, specifically disclosing a gear pump with external cooling of the packing seal, including a pump body and a main shaft. A drive gear is fixedly installed on one end of the surface of the main shaft. A sealing shell is fixedly installed on the surface of the pump body. A packing groove is formed on the surface of the sealing shell. A liquid delivery chamber is formed inside the sealing shell. A cover is fixedly installed on the surface of the sealing shell. A circulation tank is fixedly installed on the surface of the pump body. A cooling component is slidably installed on the surface of the main shaft. Coolant is added into the circulation tank. When the pump body drives the main shaft to rotate, the coolant can be delivered to the inside of the packing groove through the meshing between the drive gear and the driven gear, thereby cooling the first and second sealing packing. The provided outlet pipe and return pipe can circulate the coolant, thereby improving the cooling effect and preventing the first and second sealing packing from getting too hot and affecting the sealing effect.
