Technical Field

[0001] The utility model relates to the technical field of firecracker manufacturing, in particular to a firecracker paper tube rolling device. Background Art

[0002] Firecrackers, also known as firecrackers, refer to products that explode when ignited and can produce effects such as popping sounds and flashes, and are mainly auditory effects. Paper tube firecrackers are an important process in the production process of paper tubes. Paper tube winding machines are used in the production process of paper tubes.

[0003] Some equipment on the market generally achieves the spiral rotation of single-layer paper tubes by driving the spiral rotation of the main shaft through the mutual coordination of worms, worm wheels, gear pairs and racks and the forward rotation of the motor. The main shaft is then reset through the reverse rotation of the motor to realize the automation of paper tube rolling.

[0004] However, in actual use, the above-mentioned equipment will produce friction with the upper surface or both sides of the feed when the roll paper is fed, which will cause the roll paper to deviate or wrinkle when it is rolled, thus making the product quality substandard; in view of this, we propose a firecracker paper tube rolling device.

[0015] Compared with the prior art, the utility model provides a firecracker paper tube rolling device, which has the following

[0016] Beneficial effects:

[0017] 1. The firecracker paper tube rolling device, in order to make the equipment easier to roll up when feeding, the paper roll is placed at the feeding port, and the paper roll passes through the feeding port to the upper surface of the pressing plate and below the electric roller. At the same time, the small electric telescopic rod is extended to make the pressing plate rise inside the limiting groove, so that the paper roll contacts the electric roller, which makes the electric roller roll the paper into a tube on the outer surface of the electric roller when it rotates. At the same time, the motor rotates the lead screw to move the slider inside the slide groove, and the slider is L-shaped, and an arc groove is provided on the upper surface of the vertical part of the slider, and the arc groove is below the electric roller. When the slider moves, the upper surface of the pressing plate contacts the outer surface of the paper tube, thereby driving the paper tube to move to the cutting component for cutting. After that, the small electric telescopic rod contracts to release the limit of the paper tube on the pressing plate, which reverses the motor to reset the slider, so that the paper roll can be easier to roll up when it is rolled up.

[0018] 2. In order to make the paper roll smoother when feeding, the firecracker paper tube rolling device makes the paper roll contact with the inner wall of the feed port and the roller arranged at the bottom of the pressing piece. This will make the movable block subject to the elastic force of the spring so that the outer surface of the roller will press the paper roll, which makes the paper roll smoother when winding, thereby improving the quality of the paper tube.

The transmission device includes a slide groove 7, a screw rod 8, a motor 6, a slider 9, a fixing plate 10, a small electric telescopic rod 11, a limit groove 13 and a pressing plate 12.

[0026] In the embodiment of the utility model, a slide groove 7 is provided on one side of the inner wall of the transmission groove 3, and a screw rod 8 is rotatably connected to one side of the inner wall of the slide groove 7. One end of the screw rod 8 passes through one side of the inner wall of the slide groove 7 and is fixedly connected to the output end of the motor 6. The position of the motor 6 is set on the side of the workbench 1 close to the feed port 2. A slider 9 is threadedly connected to the outer surface of the screw rod 8. The slider 9 is L-shaped, and an arc groove is provided on the top of the vertical part of the slider 9. There are two sliders 9, and the two sliders 9 are symmetrically arranged at the center of the pressing plate 12. The size of the slider 9 is adapted to the size of the slide groove 7. A fixed plate 10 is fixedly connected to one side of the slider 9. The fixed plate A small electric telescopic rod 11 is fixedly connected to the upper surface of 10, and the top of the small electric telescopic rod 11 is fixedly connected to the bottom of the pressing plate 12. A limiting groove 13 is provided on one side of the slider 9, and a pressing plate 12 is clamped inside the limiting groove 13.
