Description

Technical Field

[0001] This utility model relates to the field of fireworks production technology, and in particular to a fireworks paper cutting device. Background Technology

[0002] Fireworks refer to the fireworks and firecrackers used in celebrations, designed to produce visual and auditory effects. They include various forms such as sky lanterns, rockets, and firecrackers. Fireworks typically consist of incendiary material, a launching device, and an outer shell. The outer shell is made of firecracker paper (or a cannon tube), and the finished long strip of paper needs to be cut to the required length.

[0003] Currently available paper cutting equipment typically requires operators to place the prepared long strips of paper tubes on a feeding rack, and then control the feeding rack to move the tubes to the cutting area via a drive device. The tubes are then gradually pushed off the feeding rack and cut with a cutter to achieve the required length. However, existing devices require manual placement and flattening of the tubes during feeding, which is quite cumbersome.

[0004] Therefore, in response to the above problems, a paper cutting device that can automatically place and flatten the cannon barrel and saves labor has been developed. Utility Model Content

[0005] In order to overcome the shortcomings of existing devices that require manual placement and leveling of the cannon barrel during material feeding, which is relatively cumbersome, this utility model provides a cannon paper cutting device that can automatically place and level the cannon barrel, saving more labor.

[0006] The technical solution of this utility model is as follows: a paper cutting device, comprising a base, a first feeding rack, a pushing module, a cutting module, a first servo motor, a rotating shaft, a second feeding rack, a hydraulic cylinder, a feeding mechanism, and a feeding module.

The screw is rotatably connected to the second feeding frame. The guide frame is connected to the upper right side of the second feeding frame, and the feeding hopper is slidably connected to the guide frame. The feeding hopper is threadedly connected to the screw. The discharge wheel is rotatably connected inside the feeding hopper. The third servo motor is connected to the left side of the feeding hopper, and the output shaft of the third servo motor is connected to the discharge wheel.

Telescopic rods are connected to the base on both the front and rear sides of the mounting plate, and support pins are evenly connected to the left side of the mounting plate.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model controls the discharge wheel to rotate through the third servo motor. The rotation of the discharge wheel transports the cannon barrel in the discharge hopper to the second discharge frame. At the same time, the first servo motor controls the rotating shaft and the second discharge frame to rotate slightly, so that the second discharge frame is in a state of front low and back high.

The second feeding rack 7 is equipped with a feeding mechanism and a feeding module 15 is connected to the second feeding rack 7. When the cannon is laid on the second feeding rack 7, the output shaft of the first servo motor 5 rotates to drive the rotating shaft 6 and the second feeding rack 7 to rotate slightly, so that the second feeding rack 7 is in a state of front low and back high.

Servo motor 14, the output shaft of the third servo motor 14 is connected to the discharge wheel 13, which transports the finished elongated cannon barrel into the discharge hopper 12. The rotation of the output shaft of the third servo motor 14 drives the discharge wheel 13 to rotate. The rotation of the discharge wheel 13 can transport the cannon barrel in the discharge hopper 12 to the second discharge rack 7. During the conveying process, the output shaft of the second servo motor 9 drives the screw 10 to rotate. Under the guidance of the guide frame 11, the rotation of the screw 10 drives the discharge hopper 12 to move backward through the thread, thereby evenly spreading the cannon barrel on the second discharge rack 7.

[0031] The feeding module 15 includes a drive motor, a lead screw, and a feeding frame. The front and rear left sides of the second feeding frame 7 are connected to drive motors, and lead screws are connected to the output shafts of the drive motors. The feeding frame is slidably connected to the second feeding frame 7, and the lead screws are threadedly connected to the feeding frame. The rotation of the output shaft of the drive motor drives the lead screw to rotate, and the rotation of the lead screw drives the feeding frame to move left and right through the thread.

[0032] It also includes a telescopic rod 16, a mounting plate 17, a support pin 18, an electric push rod 19, and a baffle plate 20. The baffle plate 20 is connected to the right side of the first feeding rack 2, and the electric push rod 19 is connected to the right side of the base 1.

During the cutting process, the support pin 18 supports the barrel and ensures its balance. After the cutting is completed, the extension end of the electric push rod 19 drives the mounting plate 17 and the support pin 18 to move to the right and reset. Under the interception of the baffle plate 20, the cut barrel is separated from the support pin 18, allowing the barrel to fall freely.

[0033] In use, this invention first needs to be installed in the operating area. Then, the prepared elongated barrel is conveyed into the hopper 12. The output shaft of the third servo motor 14 rotates, driving the discharge wheel 13 to rotate. The rotation of the discharge wheel 13 conveys the barrel from the hopper 12 to the second discharge rack 7. Simultaneously, the output shaft of the first servo motor 5 rotates the rotating shaft 6 and the second discharge rack 7 slightly, causing the second discharge rack 7 to be in a forward-lower-backward-high position. The second discharge rack 7 is supported by the hydraulic cylinder 8. During the conveying process, the output shaft of the second servo motor 9 rotates, driving the screw... The screw 10 rotates, and under the guidance of the guide frame 11, the screw 10 rotates, driving the feeding hopper 12 to move backward through the thread. This allows the cannon barrels to be evenly laid on the second feeding frame 7, preventing the cannon barrels from tilting during the laying process. After the cannon barrels are laid, the output shaft of the first servo motor 5 rotates, driving the rotating shaft 6 and the second feeding frame 7 to rotate and reset slightly, making the second feeding frame 7 horizontal. Then, the output shaft of the drive motor in the feeding module 15 rotates, driving the lead screw to rotate. The rotation of the lead screw drives the feeding frame to move to the right through the thread. At this time, the telescopic mechanism of the pushing module 3... The component drives the pusher plate upward, moving it away from the base 1. After the feeding frame completely pushes the cannon barrel on the second feeding frame 7 onto the first feeding frame 2, the drive motor in the feeding module 15 controls the lead screw to move the feeding frame to the left to reset. Then, the drive motor in the pushing module 3 drives the lead screw to rotate. The rotation of the lead screw drives the pusher frame and pusher plate to gradually move to the right through the thread. The movement of the pusher plate drives the cannon barrel to gradually move to the right. At this time, the telescopic end of the electric push rod 19 drives the mounting plate 17 and the support pin 18 to move to the left, so that the support pin 18 passes through the baffle plate 20. The baffle plate 20 blocks and limits the barrel on the first feeding rack 2, while the support pin 18 is inserted into the barrel. Then, the drive motor in the cutting module 4 drives the lead screw to rotate. The rotation of the lead screw drives the cutter to move backward through the thread, thereby cutting the barrel. During the cutting process, the support pin 18 supports the barrel to ensure its balance. After the cutting is completed, the extension end of the electric push rod 19 drives the mounting plate 17 and the support pin 18 to move to the right to reset. Under the interception of the baffle plate 20, the cut barrel is separated from the support pin 18, allowing the barrel to fall freely.
