Description

Technical Field

[0001] The utility model belongs to fireworks machinery, in particular to an improved label feeding mechanism of a paper tube carrying machine for bead-spitting fireworks. Background Art

[0002] In the prior art, there are paper tube carrying machines for spitting beads type fireworks, such as Figure 1 As shown, it includes a frame 1, on which is provided a negative pressure conveying mechanism 2 for using negative pressure to absorb and convey labels, a label feeding mechanism 3 arranged below the conveying mechanism 2 for lifting and adsorbing labels on the negative pressure conveying mechanism 2, a gluing mechanism 4 arranged at the lower front end of the negative pressure conveying mechanism 2 for gluing the labels, a paper tube conveying mechanism 6 arranged at one side of the rear end of the negative pressure conveying mechanism 2 for feeding paper tubes of bead-spitting fireworks to the negative pressure conveying mechanism 2, a labeling mechanism 5 arranged at the upper rear end of the negative pressure conveying mechanism 2 and connected with the paper tube conveying mechanism 6 for pasting the glued labels on the negative pressure conveying mechanism 2 onto the loaded paper tubes of bead-spitting fireworks, and a fan 7 arranged at the front end of the frame 1 for providing negative pressure to the negative pressure conveying mechanism 2, wherein the negative pressure conveying mechanism 2 includes a conveying frame 201 provided with negative pressure by the negative pressure fan 7 and a conveyor belt 202 with adsorption holes wound around the conveying frame 201. During production, the label feeding mechanism 3 lifts the label as a whole through the feeding mechanism, and then uses the negative pressure generated by the conveying frame 201 and the conveying belt 202 in the negative pressure conveying mechanism 2 above the label feeding mechanism to absorb the label paper and then convey it, thereby completing the grabbing and conveying of the label paper. In this label grabbing and conveying method, when the label paper is damp or static electricity exists, there will be adhesion between the label papers, and it is easy for the negative pressure conveying mechanism to grab more than two label papers when grabbing the label, which seriously affects the subsequent post-gluing and other processes, and ultimately affects the production efficiency of the equipment and the quality of the label. Therefore, it is necessary to improve the label feeding mechanism 3. Utility Model Content
