Abstract
The utility model discloses a non-powered loading dust-proof device including a fixed hopper, a telescopic connection member and a sealed frame which covers outside a feed mouth of the fixed hopper, an inner edge of the sealed frame is connected with the feed mouth by the telescopic connection member, guide slopes are provided at two sides of the sealed frame opposite to a transport direction. When a turnover box on a transport device achieves near the feed mouth, an upper edge of the turnover box is contacted with the guide slopes of the sealed frame and lifts the sealed frame, and when the turnover box achieves under the feed mouth, the sealed frame is fitly overlaied on the upper edge of the turnover box by its weight, in this way, good sealing is formed between the feed mouth and the turnover box, thereby dust in materiels during packaging would not leak from a joint of the fixed hopper and the turnover box. The dust-proof device of the utility model needs no additional power, has a simple structure, safety, relizbility and a low error rate.
Description
Technical field
The utility model relates to the material loading facilities, particularly relates to a kind of dust keeper that dust leaks that is used for preventing when material loads.
Background technology
Doing or during than dried particles (short silk) shape material vanning owing to have certain clearance between the Turnover Box that fixing vanning or blanking port and replacement are moved, case or during blanking in the case air-flow excessive meeting causing material leak along with air-flow flies upward to the outside.Existing similar loading dust keeper all is to adopt dustproof mouthful of pneumatic lifting or dustproof mouth is close in the container lifting to reach sealing purpose, mainly deficiency is that dustproof mouth is big and big or small uncertain to Turnover Box suppressing action power, brings error bigger to need the equipment of Weighing when casing; Other can bring the shortcoming that investment is big and the pressurized air consumption is bigger concerning the packaging system of many vanning mouths; And pneumatic system also can influence the reliability of system to a certain extent than labyrinth.
The utility model content
The technical problems to be solved in the utility model provides the simpler loading dust keeper of a kind of structure.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of unpowered loading dust keeper, comprise stationary hopper, a flexible attaching parts and a sealing frame, described sealing frame is enclosed within the outside of stationary hopper feed opening, be tightly connected by flexible attaching parts between the inner edge of sealing frame and the feed opening, the both sides of the relative throughput direction of sealing frame are provided with guiding surface.
Dust keeper of the present utility model is provided with a sealing frame that can fluctuate below stationary hopper, in the time of near the Turnover Box on the load transfer device arrives feed opening, the upper edge of Turnover Box contacts and will seal frame with the guiding surface of sealing on the frame and upwards lifts, when Turnover Box arrive feed opening under the time, the sealing frame relies on deadweight just in time to be pressed on the upper edge of Turnover Box, so just form better seal between feed opening and Turnover Box, the dust during vanning in the material just can not leak out from the joint of stationary hopper and Turnover Box.Dust keeper of the present utility model need not additionally to provide power, and is simple in structure, safe and reliable, fault rate is low, and only there is the gravity of sealing frame to act directly on the Turnover Box, very little and big or small fixing to the influence of weighing system, help controlling exactly oxed weight.
As improvement of the technical scheme, be provided with hanging scroll in the side of stationary hopper, the sealing frame is provided with hanger, and hanger is provided with the triangle earhole, and the sealing frame is suspended on the hanging scroll by the triangle earhole on the hanger.When the sealing frame hung down, by the weight that hanger bears the sealing frame, the triangle earhole on the while hanger allowed to seal frame again and rises under the promotion of Turnover Box.This structure make between sealing frame and the stationary hopper be connected more reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model dust keeper.
Fig. 2 is the front elevation of sealing frame.
The mechanism of the utility model dust keeper when Fig. 3, Fig. 4, Fig. 5 show vanning.
The specific embodiment
As shown in Figure 1 and Figure 2, sealing frame 3 is enclosed within the outside of stationary hopper 1 feed opening, fix the soft fabric of a circle along the edge of feed opening as flexible attaching parts 2, the lower end of flexible attaching parts 2 is fixed on the inner edge of sealing frame 3, so just forms telescopic being tightly connected between stationary hopper 1 and sealing frame 3.The top of sealing frame 3 is provided with four hangers 31, all is provided with 32, four hangers of triangle earhole on each hanger 31 and hangs on the hanging scroll 11 of stationary hopper side by triangle earhole 32.One side of sealing frame 3 is provided with guiding surface 33, as Fig. 3,4, shown in 5, in the time of near the Turnover Box on the load transfer device 4 arrives feed opening, the upper edge of Turnover Box 4 contacts and will seal frame 3 with the guiding surface 33 of sealing on the frame 3 and upwards lifts, when Turnover Box 4 arrive feed openings under the time, sealing frame 3 relies on deadweight just in time to be pressed on the upper edge of Turnover Box 4, so just between feed opening and Turnover Box, form better seal, dust during vanning in the material just can not leak out from the joint of stationary hopper 1 with Turnover Box 4, has just reached the effect of good sealing and dustproof by this simple structure and investment seldom.
