The packaging machine is composed of mechanical and electric control parts. The mechanical part includes volumetric filling and weighing mechanism composed of upper hopper, rotary table and tray, automatic bag making mechanism, pneumatic sealing mechanism and synchronous pulley transmission mechanism. The electric control part includes logic action control unit and temperature control unit, which is controlled by Microcomputer and processing program. The whole machine has the advantages of compact and simple structure, convenient adjustment, reliable performance and stable quality.

The utility model relates to an automatic weighing and packaging machine composed of a mechanical part and an electric control part. The mechanical part comprises a filling and weighing mechanism, an automatic bag making mechanism, a sealing mechanism and a transmission mechanism. The automatic bag making mechanism is composed of a belt shaft arranged in sequence, a horizontal transition shaft, a photoelectric switch on it and a forming shoulder collar. The sealing mechanism is composed of a longitudinal sealing block on the side of the blanking tube, a supporting platform under the blanking tube The utility model is composed of a pair of transverse sealing clamps and blades in the supporting platform, and the longitudinal sealing block and transverse sealing clamp contain heating pipes; The electric control part is controlled by microcomputer and processing program, including logic action control unit and temperature control unit. The logic action control unit receives the input signal of the mechanical part from the input template and sends the control command from the output template after being processed by microcomputer program. The temperature control unit inputs the temperature signal from the temperature sensor and processed by the temperature controller, The output power driver controls the temperature of the heating pipe of the longitudinal sealing block and the transverse sealing clamp; The automatic weighing and packaging machine is characterized by:

(1) The transmission mechanism is driven by the motor through the reducer to drive the rocker arm and vertical synchronous pulley group: the motor is matched with the reducer shaft and located at the base of the packaging machine, the rocker arm is perpendicular to the reducer transmission shaft, one end is a fixed shaft on the base of the packaging machine, the other end is connected with the chain, and the chain is matched with the sprocket transition shaft fixed at the horizontal position on the upper part of the packaging machine The sprocket transition shaft passes through the sprocket axis and is fixed, and the chain matched with the sprocket is connected with the supporting platform. The rocker arm can drive the supporting platform up and down through the chain, sprocket transition shaft and sprocket; The driving wheel of the vertical synchronous belt wheel set is fixed on the transmission shaft of the reducer and perpendicular to it, the driven wheel is located in the middle of the packaging machine, the bevel gear is fixed on the shaft, the driving wheel of the horizontal synchronous belt wheel (aluminum synchronous belt wheel) set is fixed above the bevel gear shaft in the vertical direction, and the bevel gear changes the rotation in the vertical direction into the horizontal direction above it, The driven wheel of the horizontal synchronous belt wheel group is coaxially fixed on the rotating shaft below the rotary table.

(2) The filling scale mechanism is composed of an upper hopper, a rotary table, a tray and a blanking pipe. The upper hopper is located above the rotary table. The rotary table is connected with the transmission mechanism through a horizontal synchronous pulley group. Four or more measuring cups are evenly arranged on the rotary table. The end face of the upper cup mouth of the measuring cup is equipped with a scraper, the end face of the lower cup mouth of the measuring cup is close to the tray, the tray is provided with a blanking opening, and the measuring cup rotates to this point in turn, The blanking port is connected with the blanking pipe.
