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, the front side plate 1c and the rear side plate 1d respectively A through hole 7 for the branch air bag 3b to protrude is provided, and the diameter of the top sheet 5 is larger than that 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 plat...

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 ejection mechanism of an explosive column forming machine. The shaping ejection mechanism comprises an air bag frame and a shaping plate, wherein an inflatable air bag is arranged in the air bag frame, an air conveying pipe communicating with the air bag is arranged on the air bag frame, and the air conveying pipe is externally connected with an air pump; the airbag comprises a main air bag and a plurality of branch air bags communicating with the main air bag, and ejecting pieces are arranged at the end parts of the branch air bags; and the shaping plate comprises a shaping clamping plate, a plurality of limiting holes for allowing the branch air bags to extend out are formed in the shaping clamping plate, shaping barrels are coaxially arranged on the limiting holes, and the ejecting pieces are slidably arranged in the shaping barrels. The shaping clamping plate is used for shaping pyrotechnic composition to form explosive columns, during use, firstly the pyrotechnic composition is loaded into each shaping barrel, the branch air bags are gradually blown up after the main air bag is fully blown up, finally, continuous air adding and pressurizing can enable the branch air bags to be ejected out, then the ejecting pieces are ejected to extend out, the ejecting pieces push the shaped explosive columns to slide outwards to be separated from the shaping barrels, manpower is not needed, and excessive part friction cannot be caused, so that the cost and the danger degree are reduced.

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...
