The invention discloses a device and a method for online removing accretions on a furnace bottom roller of a heat treatment furnace. The device comprises a steel plate placed on the furnace bottom roller, wherein the steel plate is a high-strength steel plate of 70mm*3,100mm*9,000mm; a herringbone opening is formed by using numerical control flame cutting equipment to cut along the length direction of the steel plate. According to the device and the method disclosed by the invention, under the state that the shut-down is not needed, tempering and normalizing temperature states of the heat treatment furnace are effectively utilized, and the treatment time is selected in the switching process of a tempering technology and a normalizing technology, so that the influence on the production efficiency caused by the treatment on the accretions of the furnace bottom roller can be effectively reduced; indentations on the lower surface of the steel plate subjected to heat treatment due to the accretions of the furnace bottom roller can be effectively removed, and further the appearance qualified rate of steel plate products subjected to heat treatment is greatly improved; compared with a traditional method, the method disclosed by the invention has the advantages of simpleness and convenience in operation, low cost and less influence on the production efficiency; a large amount of labor and material resources are reduced; meanwhile, the quality of the steel plate is effectively improved.

The invention belongs to the technical field of sewing equipment, and particularly relates to a switching structure of a button sewing machine and a bar tacking machine. A bar tacking adapter or a button sewing adapter is arranged at the front end of a supply frame. Correspondingly, a bar tacking presser foot device is connected to the bar tacking adapter, or a button sewing presser foot device is connected to the button sewing adapter. According to the switching structure, the button sewing adapter and the bar tacking adapter are respectively used for connecting the button sewing presser foot device and the bar tacking presser foot device with the supply frame, and the button sewing machine and the bar tacking machine can be switched as long as three or four parts are replaced, so that ordinary operators can also realize switching, utilization cost and labor cost are saved, and detachment and installation are convenient. Meanwhile, switching time is reduced, and the influence on working efficiency is reduced.

The invention discloses a duct piece production control system and a duct piece production system. The duct piece production control system comprises an actuating mechanism, a programmable controller, an information receiving unit, a communication unit and an interface displayer, wherein the actuating mechanism comprises duct piece moulds, a carrying trolley, a vibrating device, a material feeding device, a maintenance room and automatic doors; the duct piece moulds are loaded and transported by the carrying trolley; the programmable controller comprises an automatic coding and identificationmodule for the moulds, an automatic positioning module for the carrying trolley, a vibrating device control module, a material feeding device control module, an automatic temperature control module for a maintenance device, an automatic door control module, an original point returning module of an assembly line, and a human-computer interface monitoring module; and the duct piece production system comprises the duct piece moulds, a transporting system, a vibrating system, a material feeding system, a maintenance system and the duct piece production control system. By adopting the duct piece production control system and the duct piece production system, the defects of low production efficiency and low safety in the prior art are overcome.
