FIG. 1 is a schematic view of a conventional discharging device;
FIG. 2 is a schematic view of the general construction of the discharge opening of the present invention when closed;
fig. 3 is a schematic view showing the general structure of the discharge opening of the present invention when opened.
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 invention relates to a discharging device of a packaging machine, which comprises a weighing hopper 2, wherein a weighing sensor 1 is arranged on the outer wall of the weighing hopper, the weighing sensor is connected with a corresponding packaging machine frame 3 in a supporting manner, a discharging opening is formed in the lower end of the weighing hopper, a material guide channel 9 is arranged below the discharging opening, the discharging opening is an arc-shaped discharging opening, an arc-shaped discharging door is arranged corresponding to the arc-shaped discharging opening and is rotatably connected with the outer side wall of the weighing hopper, a poking rod 6 is arranged on the outer side wall of one end of the arc-shaped discharging door, an arc-shaped discharging door opening and closing driving device is arranged corresponding to the poking rod, and the arc-shaped discharging.
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 invention is connected with a frame of a packaging machine only through a weighing sensor when in installation, a discharge opening below a weighing hopper is designed into an arc-shaped discharge opening, and an arc-shaped discharge door is matched and designed at the same time, the arc-shaped discharge door consists of an arc-shaped valve plate and sector plates arranged at two sides of the arc-shaped valve plate, the sector plates at two sides are rotationally connected with the outer side wall of the weighing hopper through a pin shaft or a pin, and a poke rod is arranged at the front end of the outer side wall of the arc-shaped 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.
