Technical Field

[0001] The utility model relates to the technical field of fireworks production, in particular to a tamping device with a positioning structure. Background Art

[0002] Charging is an important process in the production of fireworks. The quality of charging directly affects the quality of fireworks, the efficiency of charging directly affects the manufacturing cost of fireworks, and the degree of automation of charging also seriously affects the safety of the production process. Existing fireworks need to be tamped using a tamping device when filling, but traditional tamping is mostly manual, and the production efficiency is low.

[0003] For example, the tamping equipment for fireworks production disclosed in announcement number CN216869349U, which fills gunpowder and the like into the fireworks paper tube that needs to be tamped, and then vertically inserts the fireworks paper tube into the positioning tube on the turntable, and then starts the lifting cylinder to rise vertically, and then vertically inserts the tamping rod into the fireworks paper tube to tamp the filling, and at the same time rotates the turntable to evenly perform the tamping process, thereby being able to perform automatic tamping.

[0004] However, when in use, the tamping structure can only move the paper tube upward to contact the tamping head for tamping work. However, since the diameters of the paper tubes are different and the size of the tamping head is fixed, it is impossible to adjust the size of the tamping head to a certain extent, so that the tamping head cannot better contact and press paper tubes of different diameters. In view of this, we propose a tamping device with a positioning structure. Utility Model Content

[0023] Specifically, the positioning structure 3 of the technical solution of the utility model includes: an electric push rod 31, a fixed frame 32, an elastic ring 33, a screw rod 34, a sleeve 35, a slide plate 36, a positioning plate 37, and a connecting rod 38.

[0024] In one embodiment of the utility model, a positioning structure 3 is provided to facilitate positioning and adjusting the diameters of the pressure plate 2 and the elastic ring 33 to a certain extent. When in use, the user can place the cylinder on the upper end of the support column 10, and then adjust the diameter of the elastic ring 33 to a certain extent according to the diameter of the cylinder. At this time, the user can drive the screw 34 to rotate by turning the handle 6.

[0025] The rotation of the screw 34 drives the sleeve 35 threadedly connected on its surface to move downward, and the movement of the sleeve 35 drives the four groups of connecting rods 38 on its side wall to move. The movement of the connecting rods 38 drives the four groups of positioning plates 37 hinged to it to move outward, and the movement of the positioning plates 37 drives the outer elastic ring 33 to move to expand the contact range, so that the pressure plate 2 and the elastic ring 33 can better contact and press the inside of the cylinder with different diameters within a certain range.

[0026] Then the user can start the electric push rod 31 to work. The model of the electric push rod 31 is CAHB-10. The output shaft of the electric push rod 31 moves the fixed frame 32 at its lower end to a certain position. Then the user can start the motor 45 to work. The output shaft of the motor 45 rotates to drive the rotating rod 46 to rotate. The rotating rod 46 rotates to drive the semi-gear 47 on its surface to rotate. The meshing between the semi-gear 47 and the rack 43 causes the rack 43 to drive the extrusion rod 41 to move downward. The semi-gear 47 continues to rotate. At this time, the semi-gear 47 is no longer meshed with the rack 43. At this time, the extrusion rod 41 is driven to move upward by the elastic force of the reset spring 44 to reset. Finally, the semi-gear 47 rotates continuously to make the extrusion rod 41 move up and down. The movement of the extrusion rod 41 drives the U-shaped frame 5 and the pressing plate 2 at its lower end to move to compact the fireworks raw materials inside the cylinder. When the pressing plate 2 is pressed downward, the elastic ring 33 therein also presses the fireworks materials, further improving the use effect of the device.

[0028] During operation, the user places the cylinder on the upper end of the support column 10, and then rotates the handle 6 to drive the screw 34 to rotate, and the rotation of the screw 34 drives the sleeve 35 to move downward, and the movement of the sleeve 35 drives the four groups of connecting rods 38 to move, and the movement of the connecting rods 38 drives the four groups of positioning plates 37 to move outward, and the movement of the positioning plates 37 drives the outer elastic rings 33 to move to expand the contact range, and then the output shaft of the electric push rod 31 moves to drive the fixed frame 32 at its lower end to move to a certain position, and then the motor 45 is started to work, and the output shaft of the motor 45 rotates to drive the rotating rod 46 to rotate, and the rotating rod 46 rotates to drive the semi-gear 47 rotates, and the rack 43 drives the extrusion rod 41 to move downward through the meshing between the half gear 47 and the rack 43.
