CN201109492Y - Conical cut-off gate of powder packaging plant - Google Patents

Abstract

The utility model belongs to the packing machinery, and relates to a cone stopping gate of the powder packing device used for controlling the opening or closing of the discharge outlet of the powder packing device. The cone stopping gate of the powder packing device includes an outlet cylinder connected with a storage device, wherein a feeding screw rod is arranged in the outlet cylinder; the lower end of the feeding screw rod is connected with a cone protruding from the outlet cylinder; a sliding sleeve which can move up and down is coated outside the outlet cylinder; the upper end of the sliding sleeve is connected to the power driving device through a handspike; the inner diameter of the sliding sleeve is smaller than the maximum diameter of the cone, so that the sliding sleeve and the cone are closed. The stopping gate has simple structure and reliable movement; the lower end of the sliding sleeve matches with the outer conical surface of the cone, so that the closing effect is remarkably increased, and the dropping and overflowing of the fine powder are prevented.

Description

Powder packaging equipment taper cut-off gate

Technical field

The utility model belongs to package packing machine, relates to a kind of powder packaging equipment taper cut-off gate that powder packaging equipment discharging opening opens and closes that is used to control.

Background technology

In powder packaging equipment, need in time to seal discharging opening after the each sand off of powder, to prevent water clock, can satisfy its operating needs for the particle existing switching mechanism of material big, that flowing power is lower, but it is thin for particle, the powder of good fluidity, damming after each sand off still can not solve preferably.After using traditional river closure mode sand off, still existing material can water clock, and perhaps the phenomenon of spill and leakage outward from the slit influences weighing or packing of next step.

Summary of the invention

Technical problem to be solved in the utility model is, provide a kind of sealing ability strong, can prevent the powder packaging equipment taper cut-off gate that fine powder material leaks outside.

Powder packaging equipment taper cut-off gate of the present utility model includes a discharge barrel that connects storage device, in discharge barrel, be provided with feeding spiro rod, be connected with a cone that stretches out discharge barrel in the lower end of feeding spiro rod, being with one in the discharge barrel periphery can upper and lower mobile slider tube, the slider tube upper end connects Power Drive Unit by push rod, the internal diameter of slip cap makes that less than the maximum gauge of cone slider tube can be closed mutually with cone.

Can also be provided with seal ring between the inwall of slider tube and the outer wall of discharge barrel.

The part that the lower end of described slider tube contacts with cone is provided with the inner conical surface that adapts with the cone tapering.

Simple in structure, the reliable in action of the utility model, in the use after primary filling finishes, move down by the radius-rod drive slider tube by Power Drive Unit, utilize the slider tube lower end to match with the outer conical surface of cone, because the buffering effect that the conical surface itself has and the adaptive ability of taper closing face, make sealing effect significantly improve, prevented the water clock and the spill and leakage of fine powder material effectively.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 4, powder packaging equipment taper cut-off gate of the present utility model includes: discharge barrel 1, be positioned at discharge barrel feeding spiro rod 2, be connected the feeding spiro rod lower end cone 3, be enclosed within the feeding tube periphery slider tube 4, be connected the push rod 5 of slider tube upper end.In the embodiment shown in fig. 4, also be provided with seal ring 6 between the outer wall of the inwall of slider tube and discharge barrel.

In the utility model use, after the sand off, drive slider tube 4 by Power Drive Unit by push rod 5 and move down each time, utilize the slider tube lower end to match, discharging opening is sealed with the outer conical surface of cone 3.As shown in Figure 3, the part that the slider tube lower end contacts with cone is provided with the inner conical surface 41 that adapts with the cone tapering, with further raising sealing ability.
