Description

The automatic tube assembling device of a kind of fireworks

Technical field

The utility model relates to the fireworks process equipment, especially relates to the automatic tube assembling device of a kind of fireworks.

Background technology

In the fireworks production process, finish punching Lian Yinhou, the fireworks paper tube that is series connection repeatedly be unfolded combination forming mutually, just can pack at fireworks paper tube.At present, finishing fireworks paper tube, to unfold the combination forming operation mostly be to adopt manual operations.Its manual operations not only production efficiency is low, and labor strength is big, is unfavorable for the fireworks automated production, is difficult to accomplish scale production.

The utility model content

Unfold the problem that the combination manual operations exists at fireworks paper tube in the above-mentioned prior art, the utility model provides a kind of production efficiency height, the low automatic tube assembling device of fireworks of operation labour intensity.

The technical scheme that the technical problems to be solved in the utility model is taked is: the automatic tube assembling device of described fireworks comprises a telescopic mould bases, the bend chute, straight runner, torque arm and thrust unit, described mould bases comprise two inner arms that an end is movably connected and two outer arms that are movably connected respectively with the two inner arm other ends and be arranged in alignment pin on the outer arm, described two torque arm, one end is movably connected, the other end of two torque arm links to each other with outer arm to hold with inner arm respectively and is movably connected, two torque arm link to each other to hold and can move in straight runner under the effect of thrust unit, torque arm is moved and can be driven outer arm and move in two bend chutes, described thrust unit comprises the push pedal that is driven by cylinder, is contained in axostylus axostyle and the spring that is contained on the axostylus axostyle in the push pedal.

The course of work of the present utility model is: original position, inner arm, the equal linear state of outer arm and torque arm, the fireworks paper tube that will connect with lead-in wire this moment is placed on the alignment pin of inner arm and outer arm, cylinder operation then, cylinder drives push pedal, under the push pedal effect, the continuous end of two torque arm moves in straight runner, drive the inner arm inwardly contraction of end that links to each other with outer arm by torque arm, drive the outer arm outer end and move in the bend chute, because compressed spring action, two inner arms link to each other and hold the starting position not change, when torque arm in straight runner after mobile a period of time, spring is stretched, and spring drives two inner arms and links to each other end along the straight runner slip, two outer arms is linked to each other with outer arm around inner arm hold swing, thereby the fireworks paper tube of having connected with lead-in wire that will be positioned on the alignment pin unfolds combination forming, after finishing, take out the fireworks paper tube of combination forming, inner arm and outer arm return to original position under the effect of thrust unit, repeat aforesaid operations, can realize continuously that fireworks organize tube automatically.

The utility model is owing to will be placed on the fireworks paper tube of lead-in wire series connection and unfold that automatic realization unfolds mutually in the mechanism; fireworks paper tube moulding production efficiency and Forming Quality have not only been improved greatly; and reduced labour intensity, simultaneously can with the supporting formation large-scale production of other fireworks manufacturing and processing equipment.
