Drawings

FIG. 1 is a schematic view of a conventional discharging device;

FIG. 2 is a schematic view of the overall structure of the discharge opening of the present invention when closed;

fig. 3 is a schematic view of the general structure of the discharge opening of the present invention.

In the figure: the automatic material guide device comprises a weighing sensor 1, a weighing hopper 2, a packaging machine frame 3, a driving cylinder 4, a sector plate 5, a poking rod 6, a shifting fork 7, an arc valve plate 8 and a material guide channel 9.

Detailed Description

Referring to fig. 2 and 3, the utility model relates to a packagine machine discharge apparatus, including weighing hopper 2, weighing sensor 1 is equipped with on the weighing hopper outer wall, and weighing sensor supports with the packagine machine frame 3 that corresponds and is connected, and weighing hopper's lower extreme is equipped with the discharge opening, is equipped with guide passageway 9 below the discharge opening, the discharge opening is convex discharge opening, is equipped with the arc discharge door corresponding to convex discharge opening, and the arc discharge door rotates with the lateral wall of weighing hopper to be connected, is equipped with poker rod 6 on the one end lateral wall of arc discharge door, corresponding to poker rod is equipped with the arc discharge door and opens and shuts drive arrangement, and the arc discharge door opens and shuts drive arrangement fixed mounting in the packagine machine frame.

Furthermore, in this embodiment the arc discharge door opening and closing driving device comprises a driving cylinder 4 fixedly mounted on the frame of the packaging machine, and a shifting fork 7 fixedly connected to the front end of a piston rod of the driving cylinder, wherein the shifting fork corresponds to the shifting rod.

Furthermore, in this embodiment, the shifting fork 7 is a U-shaped fork structure disposed in a lying position, and a U-shaped portion of the U-shaped fork structure is used for shifting the shifting rod.

Further, in this embodiment, the arc discharge door is composed of an arc valve plate and sector plates 5 arranged on both sides of the arc valve plate 8, and the sector plates on both sides are rotatably connected with the outer side wall of the weighing hopper.

The utility model discloses just be connected with the packagine machine frame through weighing sensor when installing, the discharge opening below the weighing hopper designs into convex discharge opening, and supporting design arc discharge door simultaneously, this arc discharge door comprises arc valve plate and the sector plate of arranging in arc valve plate both sides, the sector plate of both sides with the lateral wall of weighing hopper through round pin axle or pin rotation connection can, the poker rod is settled at the lateral wall front end of arc valve plate; drive actuating cylinder and shift fork then and break away from the weighing hopper completely and settle in the packagine machine frame, specific theory of operation is like: the weighing hopper is not provided with any pneumatic element, and the arc-shaped discharge door is contacted with the shifting fork below the driving cylinder when the weighing and discharging are finished. When unloading is needed, the driving cylinder drives the shifting fork to lift up, the shifting fork drives the shifting rod and the arc valve plate to rotate upwards, and the arc unloading door opens the unloading at the moment; after unloading, drive actuating cylinder and promote the shift fork downwards, the arc is unloaded the bin gate and is then closed, and the arc is unloaded the bin gate and is not had any contact with the shift fork on the cylinder when the closure state, and the arc is unloaded the bin gate and can be kept the closure state under the condition of dead weight. Therefore, when the weighing hopper is used for weighing and metering, no vibration generated by the working of any pneumatic element influences the precision of the weighing hopper, and the material of the weighing hopper cannot be blown and scattered under the condition of no air source.

The weighing hopper in the embodiment can be supported by a single point at the center, and can also be supported by three points at the sides to be provided with the weighing sensors to stabilize the weighing hopper; the weighing sensor in the embodiment can be purchased directly from the market, for example, a series of sensors produced by the Union Thailand sensor company can be selected, and the weighing sensor can be installed and used completely according to the requirement and the cost performance.
