Abstract

The utility model discloses a gunpowder mixing and feeding device for firecracker charging machine, which comprises a pair of square feed hopper with cover, at least two mixers juxtaposed on the bottom the square feed hopper, semicolumn screen meshes matching with each mixer and a plurality of resilient sheets evenly and circumferentially distributed on both ends of the mixers. A gunpowder receiving and conveying belt arranged under the square feed hopper and tightly against the semicolumn screen meshes, receives the primarily mixed gunpowder and conveys the gunpowder to a mixing and feeding roller which rotates in a fixed direction. The mixing and feeding roller has a dust-absorbing net arranged on the cylindrical side surfaces thereof. T he upper chamber of the mixing and feeding roller is in operation in a positive pressure zone, and the lower chamber of the mixing and feeding roller is in operation in a negative pressure zone. A lateral shaking and mixing sieve and a longitudinal shaking and mixing sieve are arranged in the positive pressure zone, and a firecracker conveyor belt is arranged in the negative pressure zone. The utility model is environmentally friendly and highly safe.

Description

A kind of spice mixing and feeding device of firecrackers cake charging machine

Technical field

The utility model relates to a kind of spice mixing and feeding device of firecrackers cake charging machine.

Background technology

Existing in recent years people attempts providing special-purpose charging machine for the firecrackers production industry; but get; all the time can't solve two hang-ups---at first being the environmental protection problem that brings in the spice mixing and the pay-off course of work, secondly is the safety problem that this device still exists.

The utility model content

The purpose of this utility model is a spice mixing and feeding device of designing a kind of firecrackers cake charging machine, and it neither the problem that spice dust flies upward can occur at work, and unforgettable safety coefficient is more arranged, and has promotional value.

The spice mixing and feeding device of a kind of firecrackers cake charging machine that the utility model relates to, it comprises frame and transmission case, it is characterized in that: it also comprises is located at a upper rack and transmission case square shaped arranged side by side and covers loading hopper, there is the bottom of covering loading hopper all to be provided with at least two agitators side by side in a square shaped, and with the supporting half-cylindrical screen cloth of each agitator, and two of every agitator is equipped with along circumferential several pieces uniform flexure strips, and flexure strip will be drawn together the wiping effect with described half-cylindrical screen cloth when rotated; Described square have cover the position that is close at least 4 half-cylindrical screen clothes under the loading hopper and be provided with spice and hold and open conveyer belt, this spice hold open conveyer belt be used for constantly admitting from square have to cover the preliminary mixing spice that loading hopper falls and pass to its batch mixing of doing directed rotation down continuously add feed roller; Described batch mixing adds its cylindrical sides of feed roller and is laid with dust absorption net, and in the upper space that batch mixing adds feed roller is between the zone of positive pressure that the blowing because of a blower forms, from top to bottom be respectively equipped with lateral shake nixing sieve and oscillation in the pitch mode nixing sieve between this zone of positive pressure, in the lower space that batch mixing adds feed roller is between the negative pressuren zone that the exhausting because of a pair of exhaust column forms, be provided with firecrackers cake conveyer belt between this negative pressuren zone, batch mixing add the nearly exit of feed roller firecrackers cake conveyer belt above also have clear up powder charge firecrackers cake upper edge sweep the medicine row brush.

In addition, the sheet number of the flexure strip that two of described each agitator is equipped with is at least 3, and the material of flexure strip is a rubber.Parallel to each other and cross section is the conveyer belt that circular sealing strip shape body is formed to described firecrackers cake conveyer belt by a plurality of, has certain interval between each adjacent strip shape body.

The beneficial effects of the utility model are: because a square shaped cover loading hopper can cover lid behind quantifying feed, do not raise up so this device does not have medicine dirt when spice is tentatively mixed; The batch mixing that its cylindrical sides is laid with dust absorption net adds feed roller, and function is marvellous especially, when its orientation rotates between the zone of positive pressure that the blowing because of a blower forms, hold by spice and to open first mixed spice meeting that the conveyer belt transmission comes and " wear net " and fall to the lateral shake nixing sieve, fall to the oscillation in the pitch mode nixing sieve again, drop on the firecrackers cake of doing to vertically move fully behind the mixing again, and in the firecrackers cake of this moment just in time is between the negative pressuren zone that the exhausting because of a pair of exhaust column forms, the spice particle that fall to this moment can not drop to outside the dust absorption net again, but be attracted to the inwall of dust absorption net, adding feed roller to batch mixing rotates once more they is brought between zone of positive pressure, enter the batch mixing of next round again, reinforced process, carry out and so forth, guarantee the cleaning of environment and the safety of production all the time; Special firecrackers cake conveyer belt can not taken unnecessary spice out of this device yet.

Description of drawings

Accompanying drawing is the side-looking structural representation of the utility model device;

Among the figure: 1 one frames, 2 one transmission cases, 3,3 ' one square loading hoppers that cover, 4 one agitators, 5 one flexure strips, 6 half cylindrical screen, 7 one spices hold and open conveyer belt, and 8 one batch mixings add feed roller, 9 one blowers, 10,10 ' one exhaust columns, 11 1 lateral shake nixing sieves, 12 1 oscillation in the pitch mode nixing sieves, 13 sweep the medicine row brush, the control devices that 14 1 band meterings show, 15 1 firecrackers cake conveyer belts, 16 1 powder charge firecrackers cakes.
