Description

Technical Field

[0001] The utility model relates to the field of fireworks production, in particular to a fireworks processing bottom mud packaging device. Background Art

[0002] In the fireworks production process, one end of the fireworks tube is sealed with mud, and then various gunpowders are filled into the fireworks tube. In the traditional production method, the filling and pressing of the bottom mud are usually done manually. This manual operation not only takes a lot of time and labor, but also has low production efficiency. It is difficult to accurately inject mud into the fireworks tube, and the quality is difficult to ensure. After the existing fireworks bottom mud packaging equipment injects mud into the fireworks tube and compacts it, the mud will be adsorbed on the device due to its stickiness, which makes it inconvenient for the operator to remove the fireworks tube, affecting production efficiency. Utility Model Content

[0003] The purpose of the utility model is to solve the above technical problems and provide a fireworks processing bottom mud packaging device which can more accurately inject mud into fireworks tubes, and can also facilitate operators to remove fireworks tubes more quickly, thereby improving production efficiency.

[0004] The technical solution is as follows: a fireworks processing bottom mud packaging device, comprising a base, a multi-stage sleeve hydraulic cylinder is fixedly connected to the top of the base, the multi-stage sleeve hydraulic cylinder is fixedly connected to a mud box on the telescopic rod above, a mud pressing plate is slidably connected to the mud box, the telescopic rod below the multi-stage sleeve hydraulic cylinder extends into the mud box, the telescopic rod below the multi-stage sleeve hydraulic cylinder is fixedly connected to the mud pressing plate, a plurality of mud injection heads are fixedly connected to the bottom surface of the mud box, each of the mud injection heads is communicated with the inside of the mud box, a bracket is fixedly connected to the base, a plurality of through holes are opened on the bracket, a firework tube is placed in each through hole of the bracket, and the bottom of each firework tube contacts the base, a limiting mechanism and a rotating mechanism are provided on the base, the limiting mechanism is used to limit the firework tube so that the mud injection can be more accurate, and the rotating mechanism is used to better remove the mud-injected firework tube from the base to improve production efficiency.

[0005] Preferably, the limiting mechanism includes a push rod, the push rod is fixedly connected to the outer wall of the mud loading box, a limiting rod is slidably connected to the base, and a return spring is connected between the limiting rod and the base.

[0006] Preferably, the lowering of the push rod will squeeze the limiting rod.

[0007] Preferably, the rotating mechanism includes a tow rod, a plurality of the tow rods are rotatably connected to the base, each of the tow rods is provided with a threaded groove, the tow rod extends into the firework tube, a transmission rod is slidably connected to the bottom of the base, and a tension spring is connected between the transmission rod and the base.

[0008] Preferably, it further comprises a top head, a plurality of the top heads are fixedly connected to the transmission rod, and one end of the top head is located in the threaded groove of the drag rod.

[0009] The beneficial effects of the utility model are: 1. The descent of the push rod will squeeze the limit rod, so that the limit rod will move toward the direction close to the firework tube, and the reset spring will be compressed. When the column mud head extends into the firework tube, the telescopic rod located at the top of the multi-stage sleeve hydraulic cylinder stops extending, the limit rod stops moving, and the bottom of the firework tube will be clamped by the base and the limit rod. The firework tube is clamped by the limit rod and the base, so that the firework tube will not shake, thereby making the mud injection more accurate and improving the production quality.

DETAILED DESCRIPTION

[0018] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0019] Embodiment 1: A fireworks processing bottom mud packaging device, such as Figure 1-Figure 6 As shown, it includes a base 1, a multi-stage sleeve hydraulic cylinder 2 is fixedly connected to the top of the base 1, a mud box 3 is fixedly connected to the telescopic rod at the top of the multi-stage sleeve hydraulic cylinder 2, a mud pressing plate 4 is slidably connected to the mud box 3, the telescopic rod at the bottom of the multi-stage sleeve hydraulic cylinder 2 extends into the mud box 3, the telescopic rod at the bottom of the multi-stage sleeve hydraulic cylinder 2 is fixedly connected to the mud pressing plate 4, a plurality of mud injection heads 5 are fixedly connected to the bottom surface of the mud box 3, each of the mud injection heads 5 is communicated with the inside of the mud box 3, a bracket 6 is fixedly connected to the base 1, a plurality of through holes are opened on the bracket 6, a firework tube 7 is placed in each through hole of the bracket 6, and the bottom of each of the firework tubes 7 is in contact with the base 1, and a limiting mechanism and a rotating mechanism are provided on the base 1, the limiting mechanism is used to limit the firework tube 7 so that the mud injection can be more accurate, and the rotating mechanism is used to better remove the mud-injected firework tube 7 from the base 1 to improve production efficiency.

[0020] The limiting mechanism includes a push rod 8, which is fixedly connected to the outer wall of the mud box 3. A limiting rod 9 is slidably connected to the base 1, and a return spring 10 is connected between the limiting rod 9 and the base 1.

[0021] The lowering of the push rod 8 will squeeze the limiting rod 9 .

[0022] At first, the mud box 3 is filled with mud for packaging the fireworks tube 7. The operator first places the fireworks tube 7 that needs to be packaged with bottom mud into the perforations of the bracket 6 in turn, and then the operator starts the multi-stage sleeve hydraulic cylinder 2. The telescopic rod of the multi-stage sleeve hydraulic cylinder 2 at the top will extend, and the extension of the telescopic rod of the multi-stage sleeve hydraulic cylinder 2 at the top will drive the mud box 3 to descend. The descent of the mud box 3 will drive the mud injection head 5 and the push rod 8 to descend, and the descent of the push rod 8 will squeeze the limit rod 9, so that the limit rod 9 will move in the direction close to the fireworks tube 7, and the reset spring 10 will be compressed. When the mud injection head 5 is extended into the fireworks tube 7, the telescopic rod of the multi-stage sleeve hydraulic cylinder 2 at the top stops extending, and the limit rod 9 stops moving. The bottom of the fireworks tube 7 will be clamped by the base 1 and the limit rod 9. At this time, the mud injection head 5 is located directly above the drag rod 11, and then the telescopic rod of the multi-stage sleeve hydraulic cylinder 2 at the bottom extends a distance, and the telescopic rod of the multi-stage sleeve hydraulic cylinder 2 at the bottom The extension of the rod will drive the mud pressing plate 4 to descend. The descent of the mud pressing plate 4 will inject the mud in the mud box 3 into the firework tube 7 through the mud injection head 5. The mud injected into the firework tube 7 will be supported by the drag rod 11 and will not fall. After the mud injection is completed, the telescopic rod of the multi-stage sleeve hydraulic cylinder 2 located at the top will extend for a section, so that the mud injection head 5 will descend to compact the mud in the firework tube 7, and then the telescopic rod of the multi-stage sleeve hydraulic cylinder 2 located at the top will shrink. The contraction of the telescopic rod of the multi-stage sleeve hydraulic cylinder 2 located at the top will drive the mud box 3, the mud injection head 5 and the push rod 8 to reset. The push rod 8 no longer squeezes the limit rod 9, and the reset spring 10 drives the limit rod 9 to reset. Then the operator removes the firework tube 7 from the bracket 6 in turn and replaces it with a firework tube 7 that has not been injected with mud. This reciprocating process realizes the automatic bottom mud packaging of the firework tube 7. The firework tube 7 is clamped by the limit rod 9 and the base 1 so that the firework tube 7 will not shake, thereby making the mud injection more accurate and improving the production quality.

[0023] Embodiment 2: Based on embodiment 1, Figure 3-Figure 6 As shown, the rotating mechanism includes a tow rod 11, and a plurality of the tow rods 11 are rotatably connected to the base 1. Each of the tow rods 11 is provided with a threaded groove. The tow rod 11 extends into the firework tube 7. A transmission rod 12 is slidably connected to the bottom of the base 1, and a tension spring 14 is connected between the transmission rod 12 and the base 1.

[0024] It also includes a top head 13. A plurality of the top heads 13 are fixedly connected to the transmission rod 12. One end of the top head 13 is located in the threaded groove of the drag rod 11. The top head 13 will squeeze the threaded groove wall of the drag rod 11. The drag rod 11 will rotate when squeezed, so that the drag rod 11 and the mud injected into the firework tube 7 are no longer so tightly adhered, thereby facilitating the operator to remove the firework tube 7 more quickly and improving production efficiency.

[0025] During the descending process of the push rod 8, the push rod 8 will hit the transmission rod 12, and the transmission rod 12 will descend due to the impact, and the tension spring 14 will be stretched. The descent of the transmission rod 12 will drive the push head 13 to descend, and the descent of the push head 13 will squeeze the threaded groove wall of the drag rod 11, so that the drag rod 11 will rotate. When the mud injection is completed, the push rod 8 rises and no longer squeezes the transmission rod 12. The tension spring 14 resets and drives the transmission rod 12 to reset. The transmission rod 12 will drive the push head 13 to rise, so that the push head 13 squeezes the threaded groove wall of the drag rod 11 again, and the drag rod 11 is squeezed and rotates in the opposite direction, so that the drag rod 11 and the mud injected into the firework tube 7 are no longer so tightly bonded, thereby facilitating the operator to remove the firework tube 7 more quickly and improving production efficiency.
