Bidirectional cylinder recoiling mechanism for firework cylinder

Abstract

The invention discloses a bidirectional cylinder recoiling mechanism for a firework cylinder, which is arranged below a tube coiling mechanism and comprises a lower clutch spindle (19), primary carrier rollers (16), a paper cutting carrier roller (7) and cutters (11), wherein the lower clutch spindle (19) which can draw apart and close with the upper clutch spindle (18) of the tube coiling mechanism synchronously is arranged under the upper clutch spindle; the primary carrier rollers (16) and two secondary carrier rollers (7), which can move relatively, are arranged on two sides of the lower clutch spindle; the primary carrier rollers are axially arranged at intervals; the cutters (11) which can rotate and swing synchronously are arranged below paper cylinders (3) positioned in the intervals of the primary carriers; and the internal circumferential surface formed by the primary rollers and the two secondary rollers can support and limit the paper cylinders. Adopting bidirectional cylinder recoiling, the mechanism avoids damaging the paper cylinders. Therefore, the integrity and strength of the paper cylinders are guaranteed, the safety of paper cylinder cutting is improved, the paper cylinder cutting efficiency is improved, and the realization of the automation and assembly line work of the paper cylinder cutting can be realized easily.

Description

technical field [0001] The invention relates to a fireworks processing mechanism, in particular to a two-way retracting mechanism for fireworks tube making. Background technique [0002] At present, the fireworks paper tubes are cut into paper tubes after being rolled into paper tubes with raw paper on the tube rolling machine. After the paper tube is rolled, it needs to be withdrawn from the tube winding machine. However, most of the existing machine unwinding methods adopt one-way unwinding. Since there are multiple paper tubes in series on the reel, one-sided unwinding will cause damage to the paper tube. Defects such as edge corners, flattening and deformation of the paper tube lead to a decline in the quality of the paper tube, and it is not conducive to the automatic return of the tube, which affects the processing efficiency of the paper tube. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides ...
