Embodiment 1

[0018] see figure 1 , figure 2 As shown, the present invention provides a shaping and ejecting mechanism of a grain forming machine, comprising an airbag frame 1 and a shaping plate 2, an inflatable airbag 3 is placed in the airbag frame 1, and a communicating airbag is installed on the airbag frame 1 The air delivery tube 4 of 3, the air delivery tube 4 is externally connected to the air pump, the air bag 3 includes a main air bag 3a and a plurality of branch air bags 3b communicated with the main air bag 3a, the end of the branch air bag 3b is provided with a top sheet 5; the shaping plate 2 includes a shaping The splint 2a, the shaping splint 2a is provided with a plurality of limit holes 2b for the extension of the airbag 3b, the limit hole 2b is coaxially provided with a shaping tube 6, and the top sheet 5 is slidably installed on the shaping tube 6 Inside.

[0019] Specifically, the shaping splint 2a is used to shape the pyrotechnic powder into a powder column. When i...

Embodiment 2

[0022] In this embodiment, one of the optimized designs is made on the basis of the above-mentioned embodiments. The airbag frame 1 includes a top plate 1a and a bottom plate 1b which are opposite and spaced apart, and a front side plate 1c and a front side plate 1c are arranged opposite and spaced between the top plate 1a and the bottom plate 1b. The rear side plate 1d, the air bag 3 is placed in the gap between the top plate 1a, the bottom plate 1b, the front side plate 1c and the rear side plate 1d, the air pipe 4 is installed on the top plate 1a, and both the front side plate 1c and the rear side plate 1d A through hole 7 for extending the branch air bag 3b is provided, and the diameter of the top sheet 5 is larger than the diameter of the through hole 7 . The airbag frame 1 forms a square frame, which can withstand the extrusion of the shaping plate 2 and protect the inner airbag 3 .

[0023] As another improvement, the end of the top plate 1a and the end of the bottom pl...

Embodiment 3

[0025] In this embodiment, one of the optimized designs is made on the basis of the above-mentioned embodiments. There are two plastic splints 2a, one of which is set close to the front side plate 1c, and the other plastic splint 2a is close to the rear Side panel 1d set. Wherein, by arranging the shaping plate 2 in two directions, the grain column can be processed in two directions at the same time, and the processing efficiency can be fully improved.

Abstract

The invention discloses a shaping and ejecting mechanism of a powder column forming machine, which comprises an air bag frame and a shaping plate. An inflatable air bag is placed in the air bag frame, and an air delivery pipe connected to the air bag is installed on the air bag holder, and the air delivery pipe is externally connected to an air pump. , the airbag includes a main airbag and a plurality of branch airbags communicated with the main airbag, and the end of the branch airbag is provided with a top sheet; The limiting hole is coaxially provided with a shaping cylinder, and the top sheet is slidably installed in the shaping cylinder. The shaping splint is used to shape the pyrotechnic powder into a powder column. When using it, first load the pyrotechnic powder into each shaping tube. After the main airbag is fully inflated, the bronchial airbags will gradually inflate. Finally, continuous air and pressure will make the bronchial airbags fully inflated. Eject out, and then push the top piece out, so that the top piece pushes the shaped powder column to slide outwards and get out of the shaping tube, without using manpower, and it will not cause too much friction of parts, which reduces the cost and risk .

Description

technical field [0001] The invention relates to the technical field of fireworks manufacturing machinery, in particular to a shaping and ejecting mechanism of a grain forming machine. Background technique [0002] At present, in the production of fireworks shells, combined fireworks, etc., some gunpowder drugs need to be pressed into cylindrical powder columns by hydraulic presses. The equipment that completes this work is called powder pressing machines or powder column forming machines, which are also directly referred to as hydraulic presses in the industry. . In the related art, after the powder column is clamped up and down by the drug pressing machine, the powder column needs to be manually pulled out for storage, and the powder column is easily damaged during the extraction process, and the waste of manpower is serious. Contents of the invention [0003] In order to solve the above-mentioned technical defects, the technical solution adopted by the present invention...
