  • Publication number: 20240132997
    Abstract: A device for preparing ultra-high purity zinc based on intelligently-controlled zone melting, including a slide platform connected with a screw through a servo control system to control movement of a heating-cooling device. A quartz tube is provided inside an induction heater to protect a melting zone. An infrared thermometer is connected to the heater, and configured to monitor temperature within the melting zone, and control power of the heater. A ring magnetic stirrer with non-contact circumferential rotation cooperates with coil to stir zinc melt. A water-cooling copper jacket is connected to two ends of the heater to cool a zinc bar, and its water inlet and outlet are connected with a water chiller. The infrared thermometer monitors temperature of the zinc bar and controls water flow of the cooling system. A lifting device is connected with a base cabinet to change inclined angle of the zinc bar.

  • Publication number: 20230380477
    Abstract: A compact cigarette manufacturing machine comprises a housing, a filling pipe, a loading element, a presser, and a push spoon. The housing encloses a material chamber having a bottom surface and an open end for receiving cut tobacco or other materials. The filling pipe is disposed on the housing to define a filling tip, and extends into a filling cavity in communication with the material chamber through an opening of the bottom surface of the material chamber. The loading element is assembled with the housing and is operable to load the materials into the filling cavity through the opening of the bottom surface of the material chamber. The presser is assembled with the housing and is operable to press the materials loaded in the filling cavity. A push spoon slidably disposed inside the filling cavity is operable to deliver the materials in the filling cavity into a cigarette tube loaded on the filling tip.

  • Publication number: 20220408796
    Abstract: The present application relates to the field of cigarette making, and discloses a manual hydraulic cigarette manufacturing machine, which comprises a housing and a frame arranged in the housing. The frame is provided with a driving shaft, a pressing assembly, a discharge spoon, a transmission assembly, a swing arm, a push assembly, and a rebound assembly. In the present invention, linkage between the driving shaft and the swing arm is generated by hydraulic cylinder. Without the resistance force between gear transmissions, the transmission loss ratio is greatly reduced.

  • Publication number: 20220053820
    Abstract: A paper buckling assembly for a cigarette manufacturing machine comprises a buckling frame having a first end and a second end. The buckling frame is configured to be coupled to a support frame of a cigarette manufacturing machine, such that the first end of the buckling frame aligns with a filling pipe of the cigarette manufacturing machine. The buckling frame carries a rear buckling element and a front buckling element. The rear buckling element is distal to the first end of the buckling frame, and the front buckling element is proximal to the first end of the buckling frame. The rear buckling element and the front buckling element are slidably disposed within the buckling frame and are connected through an elastic member. The rear buckling element includes a catch member for engagement with an actuating assembly of the cigarette manufacturing machine.
