Description

Technical Field

[0001] This utility model relates to the field of fireworks and firecrackers production technology, specifically to a fireworks and firecrackers production loading equipment. Background Technology

[0002] Fireworks and firecrackers refer to arts and crafts products made from gunpowder, which are used to burn (explode) through an ignition source and are accompanied by sound, light, color, smoke, fog and other effects.

[0003] For example, a fireworks and firecrackers production loading device with authorization announcement number "CN222257960U" adds gunpowder for fireworks and firecrackers production into the hopper. The gunpowder enters the interior of the fireworks tube through a feeding pipe and a sleeve, thus loading the gunpowder. The height of the sleeve can be adjusted, making it less likely to spill when loading lower fireworks tubes. However, this device is not convenient for simultaneously and quickly changing multiple gunpowder-filled paper tubes. The device only involves inserting the paper tube into a groove on the surface of the turntable and then removing it, making it inconvenient to use. Furthermore, the device is not convenient for changing paper tubes, making it unsuitable for processing paper tubes of different diameters. Utility Model Content

[0004] The purpose of this invention is to solve the problems of inconvenience in using the device and the difficulty in processing paper tubes of different diameters, and to propose a loading device for fireworks and firecrackers production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a fireworks and firecrackers production charging equipment, including a frame and a horizontal plate. The upper end of the frame is fixedly connected to the horizontal plate, and the lower end of the frame is rotatably connected to the output shaft of a servo motor through a bearing. A pressing device is provided on the upper left side of the horizontal plate. The output shaft of the servo motor is fixedly connected to a disc. A replacement device is provided on the upper end of the disc. Grooves are symmetrically opened on the surface of the disc, and threaded holes are symmetrically opened on the surface of the disc.

[0006] This setting allows the servo motor to receive different pulse signals and drive the disk to rotate at a specified angle.

[0007] Preferably, the pressing device includes a bracket and a multi-stage electric push rod. The lower end of the bracket is fixedly connected to a horizontal plate, the inner wall of the bracket is fixedly connected to the multi-stage electric push rod, the telescopic end of the multi-stage electric push rod passes through the horizontal plate, the telescopic end of the multi-stage electric push rod is fixedly connected to a connecting block, and the lower end of the connecting block is threadedly connected to a straight rod.

[0008] This feature allows the gunpowder to be compacted using a pressing device.

[0009] Preferably, the right end of the horizontal plate is fixedly connected to the pipe, and the lower end of the pipe passes through the horizontal plate.

[0010] Preferably, the lower end of the frame is fixedly connected to the support frame, and the inner wall of the support frame is threadedly connected to the outer wall of the servo motor by multiple screws.

[0011] Preferably, the replacement device includes positioning pins and a grooved plate. The lower end of the grooved plate is in contact with the disc. Positioning pins are symmetrically fixedly connected to the lower end of the grooved plate. The outer walls of the positioning pins on both sides are inserted into the disc. The grooved plate is threadedly connected to the disc by two bolts.

[0012] This feature allows for the replacement of trays, accommodating a wide variety of different sizes of firework tubes filled with propellant.

[0013] Preferably, the inner wall of the grooved disk is in contact with the tray, the upper end of the tray has a groove, and both the grooved disk and the disc have openings on their surfaces.

[0014] The present invention discloses a loading device for fireworks and firecrackers production, the advantages of which are as follows: through the cooperation of the replacement device and the disc, the grooved disc can drive the pallet to rotate synchronously, so that the positions between the two paper tubes can be interchanged, allowing the paper tube to move directly below the pipe. A measured amount of gunpowder is added to the inside of the paper tube through the pipe. After loading is completed, the above operation can be performed continuously. When loading is completed, the telescopic end of the multi-stage electric push rod extends and drives the straight rod to move downward synchronously through the connecting block, so that the straight rod can be inserted into the inside of the paper tube to compact the gunpowder inside the paper tube. After the loading operation is completed, the disc rotates back to the initial position, and the operator can easily remove the pallet through the openings on the surface of the disc and the grooved disc, and replace it with a new pallet to continue processing. By replacing the entire pallet, the replacement of the paper tube containing gunpowder can be made faster.

[0015] With the cooperation of the pressing and changing devices, the operator removes the tray, rotates the bolts on both sides to remove the grooved plate, and replaces it with a grooved plate of different inner diameter. The operator then inserts the positioning pin at the bottom of the new grooved plate into the disc and tightens the bolts on both sides again. By replacing the tray with trays of different diameters and surface through holes, the tray can be used to place and process fireworks and firecrackers of different specifications. At the same time, the operator rotates the straight rod to remove the rotating rod, replaces it with a rotating rod of different diameter and length, and rotates the straight rod again to connect it with the connecting block by thread for further processing. By changing the structure in this device, it is possible to facilitate the loading of paper tubes of different diameters with explosives. Attached Figure Description

[0021] Working principle: When loading explosives during the production of fireworks and firecrackers: The operator inserts multiple paper tubes filled with gunpowder into the grooves on the surface of the pallet 5. The operator places the pallet 5 on the surface of the grooved disk 902 and controls the servo motor 6 to operate, causing the output shaft of the servo motor 6 to rotate a specified angle at a time. The servo motor 6 can drive the grooved disk 902 to move synchronously through the disc 8, and the grooved disk 902 can drive the pallet 5 to rotate synchronously, allowing the positions of the two paper tubes to be interchanged, so that the paper tubes can move directly below the pipe 4.
