The packaging machine is composed of an electric control and a mechanical part. The mechanical part comprises a volumetric filling and weighing mechanism composed of an upper hopper, a turntable and a tray, an automatic bag making mechanism, a pneumatic sealing mechanism and a synchronous pulley transmission mechanism, and the electronic control part includes a logic action. The control unit and the temperature control unit are controlled by a microcomputer and a processing program. The whole machine is compact, simple, convenient to adjust, reliable in performance and stable in quality. The typical material is iodized salt when the packaging speed is >50 packs/min, the average error is <1, and the seal pass rate is >98%. It can be used for fast automatic weighing and packaging of powdery and granular materials.
The utility model relates to an automatic weighing packaging machine composed of an electric control part and a mechanical part. The mechanical part comprises a filling weighing mechanism, an automatic bag making mechanism, a sealing mechanism and a transmission mechanism (synchronous belt, synchronous belt pulley), and the automatic bag making mechanism is arranged in sequence The belt shaft of the cloth, the horizontal transition shaft and the photoelectric switch thereon and the formed shoulder collar are composed of a longitudinal sealing block on the side of the blanking tube, a pallet below the feeding tube, a pair of transverse sealing clips in the pallet and The blade is composed of a longitudinal block and a horizontal seal. The electronic control part is controlled by a microcomputer and a processing program, and includes a logic action control unit and a temperature control unit. The logic action control unit receives the input signal of the mechanical part from the input template. After the microcomputer program processes, the control command is issued by the output template, and the temperature control unit inputs the temperature signal by the temperature sensor, and after being processed by the temperature controller, the output power driver performs temperature control on the heating tubes of the vertical block and the horizontal seal; The weighing packaging machine is characterized by:
(1) The transmission mechanism is driven by the motor through the reducer to drive the rocker arm and the vertical timing pulley set: the motor and the reducer shaft are matched, located at the base of the packaging machine, the rocker arm is perpendicular to the transmission shaft of the reducer, and one end is a fixed shaft at the base of the packaging machine. The other end is coupled with the chain, the chain is matched with the sprocket transition shaft fixed to the upper horizontal position of the packaging machine, the sprocket transition shaft is fixed through the sprocket axis and fixed, and the chain engaged with the sprocket is coupled to the pallet, the rocker arm The chain, the sprocket transition shaft and the sprocket can drive the pallet up and down; the vertical timing pulley group drive wheel is fixed on the reducer drive shaft and perpendicular thereto, and the passive wheel is located in the middle of the packaging machine, and the shaft is fixed on the bevel gear, horizontal The timing pulley group driving wheel is fixed above the vertical bevel gear shaft, the bevel gear transforms the vertical rotation into the upper horizontal rotation, and the horizontal timing pulley group passive wheel is coaxially fixed on the rotating shaft below the turntable. .
(2) The filling and weighing mechanism is composed of an upper hopper, a turntable, a tray and a feeding tube. The upper hopper is located above the turntable, and the turntable is connected to the transmission mechanism through the horizontal timing belt set, and uniformly arranges four or more measuring cups on the turntable. The measuring cup has a scraper on the end face of the cup, and the end face of the measuring cup is closely attached to the tray. The tray has a lower opening and a measuring cup which are sequentially rotated to the lowering, and the lower opening communicates with the discharging tube.
