Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a top sealing device for processing and producing fireworks shells, comprising a housing 1, a positioning mechanism 2 disposed in the lower middle part of the inner wall of the housing 1 for positioning the position of the fireworks shell, a cleaning mechanism 3 fixedly connected to the upper middle part of the inner wall of the housing 1 for cleaning debris generated at the sealing point, a telescopic mechanism 4 slidably connected to the rear side of the inner bottom wall of the housing 1, a sealing pressure head 5 slidably connected to the top wall of the middle part of the housing 1, and a metal clamp 6 fixedly connected to the right side of the inside of the housing 1. The device includes a slide plate 201, which is located in the lower middle part of the inner wall of the outer casing 1. A slide column 202 is fixedly connected to the right side of the middle part of the slide plate 201. A slide groove 203 is provided on the right side of the outer wall of the slide column 202. A fixing ring 204 is slidably connected to the left side of the outer wall of the slide plate 201. A moving component 205 is slidably connected to the right side of the outer wall of the slide column 202. The moving component 205 includes a motor 2051, which is located in the lower middle part of the inner wall of the outer casing 1. A cylinder 2052 is fixedly connected to the output end of the motor 2051.

[0032] Specifically, the top sealing device for the processing and production of fireworks shells uses the outer shell 1 as the main supporting frame, providing stable support and protection for the internal functional mechanisms. The positioning mechanism 2, located in the lower middle part of the inner wall of the outer shell 1, is the main structure to ensure the precise positioning of the fireworks shells. The positioning mechanism 2 consists of a sliding plate 201, a sliding column 202, a sliding groove 203, a fixing ring 204, and a moving component 205. The sliding column 202 on the right side of the middle part is a key structure. The sliding groove 203 on the right side of its outer wall cooperates with the moving component 205 to convert rotational motion into linear motion. The fixing ring 204, which is slidably connected to the left side of the outer wall of the sliding plate 201, can move flexibly under the drive of the sliding column 202 to accurately clamp the fireworks shells and ensure their stability during the sealing process. The moving component 205 is powered by a motor 2. 051 and cylinder 2052 form a motor. 2051 is firmly installed in the lower middle part of the inner wall of the outer shell 1. Its output end directly drives the cylinder 2052 to rotate at high speed. The outer wall of the cylinder 2052 meshes with the sliding column 202, so that the sliding column 202 can move linearly back and forth along the sliding groove 203, thereby driving the fixing ring 204 to achieve rapid positioning and stable clamping of the firework shell. In the upper middle part of the inner wall of the outer shell 1, a cleaning mechanism 3 is fixedly connected, which can clean up the debris and dust generated at the sealing point of the firework shell in time. The telescopic mechanism 4 set on the rear side of the inner wall of the outer shell 1 can be flexibly adjusted according to the height of the firework shell. The sealing head 5, which is slidably connected to the top wall in the middle, can accurately press down to complete the pressing and sealing process of the top of the firework shell with the cooperation of the telescopic mechanism 4 and the positioning mechanism 2.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The cleaning mechanism 3 includes a support block 301, which is located on the upper left side of the outer casing 1.

The cleaning assembly 307 includes a second motor 3071, which is fixedly connected to the upper left side of the outer casing 1. A rotating shaft 3072 is fixedly connected to the output end of the second motor 3071. A rotating shaft 3073 is rotatably connected to the front outer wall of the first rotating shaft 3072.

[0034] Specifically, the cleaning mechanism 3, as the main structure ensuring sealing quality, is installed on the upper left side of the outer casing 1. The support block 301 is fixed to the inner wall of the outer casing 1. A threaded cylinder 302 with precision threads is provided on the front side of its inner wall. Through meshing with the rotating screw 303, a helical transmission structure is formed, which can convert rotational motion into linear motion. The top front side of the threaded cylinder 302 is also provided with a toothed structure, which meshes with the gear plate 304 to ensure the accuracy and stability of the transmission. A cleaning brush 305 is fixed in the middle of the top wall of the gear plate 304, which can effectively remove residual debris and dust at the sealing point. The rear end of the rotating screw 303 extends out to form the support block 301, which is fixedly connected to the moving screw. Block 306, the cleaning component 307 consists of motor 3071 and rotating shaft 3072 and rotating shaft 3073. Motor 3071 is fixed to the upper left side of the outer casing 1. Its output end drives rotating shaft 3072 to rotate at high speed. The front side of the outer wall of rotating shaft 3072 is connected to rotating shaft 3073. Through gear or belt transmission, it drives the threaded drum 302 and the gear plate 304 to rotate synchronously. When motor 3071 starts, rotating shaft 3072 drives rotating shaft 3073 to rotate, which in turn drives the threaded drum 302 to rotate, so that the rotating screw 303 moves axially, pushing the moving block 306 to drive the cleaning brush 305 to perform reciprocating linear motion to efficiently remove the debris generated during the sealing process.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The telescopic mechanism 4 includes a fixed frame 401, which is fixedly connected to the front side of the inner wall of the outer shell 1. An adjustment plate 402 is fixedly connected to the top of the outer wall of the fixed frame 401. A pushing component 403 is fixedly connected to the bottom rear side of the adjustment plate 402. The pushing component 403 includes an electric push rod 4031, which is slidably connected to the rear side of the inner wall of the outer shell 1. A metal push rod 4032 is slidably connected to the top of the outer wall of the electric push rod 4031. A lamp holder 8 is fixedly connected to the front side of the inner top wall of the outer shell 1. A lamp 7 is installed at the bottom of the outer wall of the lamp holder 8. A lamp holder 8 is fixedly connected to the front side of the inner top wall of the outer shell 1. Multiple support plates 9 are fixedly connected to the left and right sides of the motor 3071. Multiple fixing blocks 10 are fixedly connected to the middle of the inner wall of the two support plates 9.

[0036] Specifically, the telescopic mechanism 4 serves as an auxiliary positioning and support device in the sealing process of the top of the firework shell. Based on the fixed frame 401, it is fixed to the front side of the inner wall of the outer shell 1 to ensure stable machine operation. The adjustment plate 402, which is fixedly connected to the horizontal plane at the top, can flexibly adjust the angle and position according to the height and size of the firework shell, thereby achieving fine-tuning of the height of the pushing component 403 and enhancing the adaptability of the equipment. The pushing component 403, composed of an electric push rod 4031 and a metal push rod 4032, serves as the main structure. The electric push rod 4031 is slidably connected to the slide rail on the rear side of the inner wall of the outer shell 1, and the metal push rod 4032 pushes the firework shell. The lamp holder 8 on the front side of the inner top wall of the outer shell 1 is equipped with a lamp 7 to provide uniform lighting for the work area. The power source motor 3071 of the cleaning mechanism 3 has support plates 9 symmetrically distributed on both sides to prevent parts from loosening and ensure the long-term stable operation of the cleaning mechanism 3.

[0037] Working principle: In this top sealing device, the output end of the motor 2051 of the moving component 205 drives the cylinder 2052 to rotate. Through the cooperation between the outer wall of the cylinder 2052 and the sliding column 202, the two sliding columns 202 make linear reciprocating motion along the slide groove 203. The top of the sliding column 202 is connected to the fixing ring 204. When the sliding column 202 moves inside the slide plate 201, the fixing ring 204 can accurately position and clamp the top of the firework shell.

[0038] In this top sealing device, the output end of motor 2 3071 drives shaft 1 3072 to rotate. During the rotation of shaft 1 3072, it drives shaft 2 3073 to rotate, converting the rotational motion into linear movement of moving block 306 on support block 301. Moving block 306 is fixedly connected to rotating screw 303. Rotating screw 303 cooperates with threaded cylinder 302, causing cleaning brush 305 fixed on moving block 306 to reciprocate along gear plate 304 to clean debris and dust from the sealing device.
