Description

TECHNICAL FIELD

[0002] The general combination scale disperses the already supplied measured material radially through the dispersion feeder, and linearly vibrates and carries the dispersed measured material towards the outside through the multiple linear feeders, so as to supply into the supply hopper respectively facing the terminal surface of each linear feeder. Each supply hopper supplies the measured material into the multiple measuring hoppers respectively located below by opening the hopper door, and the combination scale selects the combination of the measuring hoppers, which is the combination of the combined weight within the specified weight range after various combinations of the weight of the measured material supplied into the multiple measuring hoppers.

[0032] Each receiving bin 200 of the multi-channel combined scale has a first door plate 220 and a second door plate 230, and by selecting to open the first door plate 220 or the second door plate 230, the metered material can be input into the inner hopper 300 or the outer hopper 400, when the weight sum of the metered material in the several receiving bins 200 reaches a preset target value, the first door plate 220 of the corresponding receiving bin 200 is controlled to be opened and then closed to input the metered material into the outer hopper 400, and then the metered material is input into the packaging machine through the second conveying pipeline 420; when the weight sum of the metered material in the several receiving bins 200 reaches the preset target value again, the first door plate 220 of the corresponding receiving bin 200 is controlled to be opened and then closed to input the metered material into the inner hopper 300, and then the metered material is input into the packaging machine through the first conveying pipeline 310, so that the material conveying efficiency and the packaging production efficiency are improved, and the structural layout of the inner hopper 300 and the outer hopper 400, the first conveying pipeline 310 and the second conveying pipeline 420 is compact and reasonable.

[0033] It should be noted that, referring to Figure 1 The utility model discloses a multi-channel combined scale's frame 100 is equipped with the central position of inner hopper 300 and outer hopper 400's directly above feed hopper 800, and the feed hopper 800 is the sleeve of the circular table shape of big down small, and the lower portion of feed hopper 800 is provided with the unloading slope surface 810 of the circular cone shape, and the outer periphery edge of the unloading slope surface 810 is provided with a plurality of feeding tracks 820 arranged in the radial direction, and the number of feeding tracks 820 is equal to the number of receiving bins 200, and a plurality of feeding tracks 820 correspond to a plurality of receiving bins 200 one by one, and the lower portion of feeding track 820 is provided with a linear vibrator extending along the length direction, and the linear vibrator drives the metered material in feeding track 820 to move from one end close to the unloading slope surface 810 to one end close to the receiving bin 200, and the receiving bin 200 is located directly below the end of the corresponding feeding track 820. It can be understood that when the metered material falls down from the feed hopper 800, the metered material moves along the slope direction of the unloading slope surface 810 towards each feeding track 820, which is beneficial to uniformly supply the metered material to the receiving bin 200 for weighing. Among them, the feed hopper 800 and the unloading slope surface 810 are concentrically arranged, and the central axis of the feed hopper 800 is the vertical axis mentioned above.

[0034] It can be imagined that when the weighing module weighs the metered material in the receiving bin 200, in order to avoid the metered material still being continuously input under the driving of the linear vibrator, each feeding track 820 is provided with a storage bin 830 directly below the end close to the receiving bin 200.

The other end of the first rotating arm (511) is connected to a first driving rod (513) opposite to the first crank (612). When the first crank (612) rotates, it contacts the first driving rod (513) to make the first rotating arm (511) rotate, thereby driving the first door panel (220) to rotate and open the lower port of the storage chamber (210). The second driver (620) includes a second motor (621) and a second crank (622) disposed on the output shaft of the second motor (621).

The other end of the second rotating arm (521) is connected to a second driving rod (523) opposite to the second crank (622). When the first crank (612) rotates, it contacts the second driving rod (523) to make the second rotating arm (521) rotate, thereby driving the second door panel (230) to rotate and open the lower port of the storage chamber (210).
