The invention relates to the technical field of graphene, in particular to a graphene raw material transfer device which comprises a spiral stirring assembly used for stirring and dispersing graphene raw materials through a stirring shaft arranged in the spiral stirring assembly; the discharging assembly is connected to a raw material to-be-output port in the lower portion of the raw material to-be-input port and used for discharging and outputting the graphene raw materials from a discharging pipe, a dust suppression device is arranged on the discharging assembly, and a blowing device is arranged in the discharging pipe; the gas-solid separation device is arranged between the outlet end of the discharging pipe and the inlet of the material receiving barrel and is used for separating the gas in the purging device from the graphene raw material; the spiral groove is formed in the inner wall of the feeding cylinder of the gas-solid separation device, gas is pressed into the conical cylinder and exhausted upwards along the exhaust pipe, and the tail end of the spiral groove is located below the bottom end of the conical cylinder; the bottom end of the feeding cylinder is an open end and communicates with an inlet of the material receiving barrel, graphene raw materials are separated under spiral centrifugal force and enter the material receiving barrel, and the situation that dust flies everywhere and pollutes the surrounding air environment is avoided.

The utility model discloses a cigarette machine cigarette froth suction device, include: mounting panel, dust absorption cover, negative pressure pipeline and rotating component, mounting panel sets up on the frame of cigarette machine, and dust absorption cover includes connecting block, fixed block and adsorption cover, and the both ends of fixed block are connected with the first end of connecting block and the top of adsorption cover respectively, and the both sides of fixed block all are provided with first air duct and second air duct, and the third air duct that communicates with first air duct and second air duct is provided on connecting block, and first air duct, second air duct communicate with adsorption cover, negative pressure pipeline is through mounting panel and communicates with third air duct, and rotating component sets up on mounting panel, and is connected with the second end of connecting block, is used for driving connecting block to rotate. The utility model utilizes first air duct, second air duct and third air duct to connect the negative pressure in negative pressure pipeline to adsorption cover, makes negative pressure wind to adsorb cigarette froth, and the simple and practical structure is convenient to operate, prevents the problem that dust absorption cover falls down fast and hurts people or damages the part.

The utility model discloses an automatic fallen wool collecting device of a wool comber, which relates to the technical field of the automatic fallen wool collecting device of the wool comber, and comprises a collecting box, and a fan is fixedly connected to the side surface of the collecting box. A blower pipe is fixedly connected to the top of a fan, a collecting box is fixed to the side face of the fan, in the rotating process of a top driving shaft, when fallen hair collected on a burr conveying belt rolls to the position close to the top driving shaft, air blown out of the inside of the blower pipe adsorbs the fallen hair on the burr conveying belt, and the fallen hair on the burr conveying belt is removed. According to the fallen wool collecting device, the fallen wool is sucked into the collecting box from the top face of the burr conveying belt and enters the middle of the collecting box to be collected, the design structure is simple, all the fallen wool can be collected, automatic collecting of the fallen wool is completed, manpower is saved, the using effect is good, the fallen wool cannot fly away in the collecting process, and pollution to raw materials and air is avoided.
