Furthermore, the utility model discloses a weighing and distributing system weighs hopper 3 through 6 drives of lift cylinder and goes up and down to the feeding that makes hopper 3 of weighing is more inseparable with the ejection of compact, prevents that the powder from spilling.
The utility model discloses a weighing and distributing system is through in the hopper 3 of weighing that glassware 2 corresponds the powder direction in the feed bin 1 down. In order to improve the stability of system when idle, the cloth system of weighing be in the discharge gate of feed bin is equipped with and is used for controlling its third control gate 11 that closes or open. Wherein, the feed bin 1 can be provided with one or a plurality of.
When the feed bin 1 is provided with one, a plurality of discharge ports are arranged on the feed bin, and the blanking device 2 is connected with the discharge ports in a one-to-one correspondence mode. When adopting a feed bin 1, only need set up a plurality of openings and can realize the independent feeding function of a plurality of glassware 2 down, adopt a feed bin 1 can simplify whole structure. Wherein, every discharge gate department all installs third control gate 11, through third control gate 11 control unloading, when the stop work, third control gate 11 closes to avoid the material to pile up in the glassware 2 always and cause too big burden to the glassware 2 down. The figure shows the construction when one silo 1 is used.
When the feed bin is provided with a plurality of, the feed bin is the same with the number of glassware down, the glassware is connected with the feed bin one-to-one. Namely, each blanking device is correspondingly matched with one storage bin, and at the moment, the blanking devices cannot be influenced mutually. And a third control gate is arranged at the discharge port of each bin.
In addition, in order to facilitate the cleaning of powder in the idle time feed bin, the utility model discloses be equipped with on the feed bin and expect opening 12 clearly. The powder in the idle bin is discharged through the material cleaning opening 12, so that the powder is prevented from being stored in the bin for a long time and the service life of the equipment is prevented from being influenced.
First control gate, second control gate and third control gate can be the gate of cylinder drive formula, also can be the gate of solenoid valve drive formula, as long as can realize the self-closing of each discharge gate or open can.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
