Description

Cover opening device of drying furnace Technical Field The utility model belongs to the technical field of drying ovens, and particularly relates to a cover opening device of a drying oven. Background The drying furnace is widely applied to a plurality of industries such as processing and manufacturing, chemical industry, food, pharmacy and the like, and is used for drying materials. In the running process of the drying furnace, the opening and closing of the furnace cover is an essential operation link for materials to enter and exit the furnace body, and the rationality of the structural design directly influences the production efficiency, the operation safety and the service life of equipment. At present, the existing uncovering device of the drying furnace mostly adopts a manual opening and closing mode, so that the mode not only consumes manpower, but also has low operation efficiency, and is difficult to meet the requirement of mass production. The mechanical auxiliary uncapping device is partially adopted, so that the structure is complex, the stability is poor, faults are easy to occur in the long-term use process, and the maintenance cost of equipment is increased. In addition, some uncapping devices lack effectual direction and bearing structure in the bell removes the in-process, lead to the bell to remove unsmoothly, appear blocking even, skew scheduling problem, not only influence uncapping efficiency, still probably cause the potential safety hazard. Meanwhile, in the connection and driving modes of the air cylinder and the furnace cover, the existing cover opening device has the problems of unstable power transmission, uneven stress of the air cylinder and the like, and the reliability and the service life of the cover opening device are further reduced. Disclosure of utility model In order to solve the technical problems, the utility model adopts the technical scheme that the cover opening device of the drying furnace comprises a furnace body, one side of the upper end of the furnace body is provided with a feed inlet, the other side of the upper end of the furnace body is provided with a discharge outlet, the feed inlet is provided with a feed furnace cover, the discharge outlet is provided with a discharge furnace cover, the cover opening device comprises a feed cylinder and a discharge cylinder, both sides of the feed inlet and both sides of the discharge outlet are respectively provided with sliding rails, the inner sides of the sliding rails are provided with pulley grooves, both sides of the feed furnace cover and both sides of the discharge furnace cover are respectively provided with pulleys, the pulleys are rotatably connected with the feed furnace cover or the discharge furnace cover, the pulleys are positioned in the corresponding pulley grooves, the upper end of the furnace body is fixedly connected with a cylinder seat, the feed cylinder and the discharge cylinder are respectively hinged with the cylinder seat, the output shaft of the feed cylinder is respectively fixedly connected with a cylinder push plate on the feed furnace cover, the output shaft of the discharge cylinder is hinged with the cylinder push plate on the feed furnace cover, and the output shaft of the discharge cylinder is hinged with the cylinder push plate on the discharge furnace cover.
