The invention discloses an explosion-proof chemical forcible entry rescue machine, and relates to the technical field of forcible entry rescue, a stainless steel forcible entry cutter for forcible entry of articles and an external force rod for additionally applying forcible entry force to the stainless steel forcible entry cutter are mounted in a forcible entry cover, and the external force rod penetrates through an outer sealing ring; the rescue device has the advantages that a double-closed barrier is constructed, external flammable and explosive gas is effectively prevented from entering or internal harmful gas is effectively prevented from leaking, the air in the forcible entry cover is extracted by the extraction pipe to form a low-oxygen environment, the air in the forcible entry cover is prevented from entering the rescue device, and the air in the forcible entry cover is prevented from entering the rescue device. The stainless steel forcible entry cutter as a core component is firm in material and not prone to generating sparks during forcible entry, the risk of spark ignition is eradicated in combination with a low-oxygen environment, the device adapts to complex environments such as combustible gas and dust in chemical places, an external force rod can apply extra forcible entry force, and it is ensured that equipment is attached to a target in the forcible entry process.

This utility model discloses an anti-aging, high-ductility PVC sheet production equipment, relating to the field of PVC sheet production. It includes a main body of equipment and PVC sheets. The inner wall of the main body is equipped with a cleaning mechanism, which includes a first cleaning roller and a second cleaning roller rotatably mounted on the inner wall of the main body. A first end-face gear is fixedly mounted at the end of the first cleaning roller, and a second end-face gear is fixedly mounted at the end of the second cleaning roller. A drive motor is fixedly mounted on the outer wall of the main body, and a drive shaft is fixedly mounted at the output end of the drive motor, with a drive gear fixedly mounted at the end of the drive shaft. A pressing mechanism is provided at the end of the second cleaning roller. This anti-aging, high-ductility PVC sheet production equipment can simultaneously perform dust removal on both the upper and lower surfaces of the sheet, forming a double-sided cleaning structure. Compared to traditional single-sided cleaning methods, it can more comprehensively remove dust adhering to the sheet surface, avoiding dust residue affecting sheet quality and subsequent use.
