Description

Technical Field

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

[0002] Currently, as a traditional celebratory item, the filling and compaction processes in the production of fireworks significantly impact product performance and safety. Currently, the filling and compaction of fireworks tubes largely relies on manual operation or simple mechanical devices, resulting in uneven compaction, low efficiency, high labor intensity, and significant safety hazards. Especially during continuous operation on production lines, traditional compaction methods are ill-suited to the demands of high-speed, continuous production, easily leading to inconsistent packing density within the fireworks tube, affecting the ignition effect, and potentially causing accidents due to insufficient compaction in certain areas. Furthermore, existing devices often lack stable control over the conveyor process, making it prone to conveyor belt vibration causing fireworks tubes to shift or tip over, further impacting compaction quality and operational safety. Therefore, there is an urgent need for a fireworks compaction device that can adapt to automated production lines, provide uniform compaction, operate stably, and is safe and reliable. Utility Model Content

[0003] To address the aforementioned problems, the present invention adopts the following technical solution: A pressing device for fireworks is provided for a fireworks tube filling production line. The fireworks tube conveyor belt is equipped with adjacent fireworks tube mounting seats. The fireworks tubes are conveyed vertically by the fireworks tube conveyor belt and pass through the pressing mechanism in sequence. The pressing mechanism includes a fixed plate and telescopic components. The pressing mechanism is fixed to the conveyor belt pulley by a vertical connecting shaft. Multiple pressing telescopic components are fixedly arranged around the fixed plate. A rotating plate is fixed at the bottom of the conveyor belt pulley. A pressing space is formed between the outer periphery of the rotating plate and the conveyor belt pulley. A guide rail is also provided on one side of the pressing mechanism and is arranged along the rotation direction of the telescopic components to press down the telescopic components when the telescopic components pass through the guide rail.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0016] Example 1: See appendix Figure 1-9 A pressing device for fireworks, used in a fireworks tube filling production line, includes a fireworks tube conveyor belt 6 with adjacent fireworks tube mounting seats 23. Firework tubes are conveyed vertically by the conveyor belt 6 and pass sequentially through a pressing mechanism 8. The pressing mechanism 8 includes a fixed disc 80 and telescopic components 83. The material inside each fireworks tube is compacted by the telescopic components 83. A vertical connecting shaft 7 is fixedly connected from top to bottom to the fixed disc 80 and the conveyor belt pulley 5. The bottom of the connecting shaft 7 is connected to a reduction mechanism 4. The fixed disc 80 and the conveyor belt pulley 5 rotate synchronously. Multiple pressing telescopic components 83 are fixedly arranged around the fixed disc 80. A rotating disc 3 is fixed to the bottom of the conveyor belt pulley 5, forming a pressing space between the outer periphery of the rotating disc 3 and the conveyor belt pulley 5. This pressing space ensures that each mounting seat 23 on the fireworks tube conveyor belt 6 has support at its bottom during the pressing process, preventing each firework tube from being compacted during the pressing process. The bottom of the mounting seat 23 cannot bear force, causing the firework tube conveyor belt 6 to twist and fail to compact. The pressing mechanism 8 is also provided with a guide rail 11 on one side, which is set along the rotation direction of the telescopic component 83. It is used to press down the telescopic component 83 when the telescopic component 83 passes the guide rail 11. Specifically, the pressing mechanism 8 is installed on the support frame 1. The support frame 1 is mainly used to support this utility model. Generally, the support frame 1 is located at the corner of the annular firework tube conveyor belt 6. The inner side of the firework tube conveyor belt 6 has a toothed structure. The outer side of the firework tube conveyor belt 6 has multiple mounting seats 23. The mounting seats 23 are used to embed the firework tubes. The conveyor pulley 5 cooperates with the firework tube conveyor belt 6. The conveyor pulley 5 has a limiting edge. The lower edge of the firework tube conveyor belt 6 contacts the rotating disk 3. The conveyor pulley 5 cooperates with the firework tube conveyor belt 6 on the firework tube filling production line. The conveyor pulley 5 rotates synchronously with the rotating disk 3. The connecting shaft 7 is connected to the transmission component 4.

[0017] The pressing mechanism 8 is also mounted on the support frame 1. The upper part of the support frame 1 has a circumferential array of multiple support plates 2. The top of each support plate 2 is in contact with the bottom of the rotating disk 3. The rotating disk 3 is also fixedly connected to the transmission assembly 4. The support frame 1 is also provided with multiple guide support columns 9. The multiple guide support columns 9 are spaced apart and are arranged in an arc shape on the outside of the rotating disk 3. Each guide support column 9 is also equipped with a sleeve 10. The far end of each sleeve 10 is fixedly connected to the guide rail 11. The guide rail 11 has a gradually decreasing slope 12 at the bottom. The height of the gradually decreasing slope 12 gradually decreases. The pressing mechanism 8 is rotated through the connecting shaft 7. During the rotation, the end of each telescopic component 83 will be under the action of the gradually decreasing slope 12, so that the telescopic component 83 will gradually compact the material in the inner firework tube until the top of the telescopic component 83 is no longer in contact with the guide rail 11, and the telescopic component 83 will reset.

[0018] See Figure 1-5 The transmission assembly 4 includes a reducer 40, which is installed at the bottom of the support frame 1. The input end of the reducer 40 is connected to the power input end, and the output end of the reducer 40 is fixedly connected to the transmission shaft 41. The power is transmitted to the rotating disk 3 through the transmission shaft 41. The transmission shaft 41 is also equipped with a first pulley 42, which is generally connected to other external drives to provide power to them. The other end of the transmission shaft 41 passes through the top of the support frame 1 and is fixedly connected to the bottom of the connecting shaft 7. The reducer 40 mainly reduces the speed of the motor and transmits the power of the motor to the connecting shaft 7. The connecting shaft 7 drives the rotating disk 3 and the pressing mechanism 8 to rotate synchronously.

[0019] See Figure 5 Each support plate 2 is also equipped with a roller 13 on its top. Each roller 13 is in contact with the bottom surface of the rotating disk 3, and there are no fewer than four support plates 2. In this way, during the overall rotation, the roller 13 can reduce friction and make the rotating disk 3 rotate more smoothly.

[0020] See Figure 3 The support frame 1 is also vertically provided with multiple limiting posts 14, which are also distributed in an arc shape. The top of each limiting post 14 is fixedly connected to an arc-shaped limiting plate 15. The gap between the inner side of the arc-shaped limiting plate 15 and the outer side of the conveyor belt wheel 5 is used for the passage of the firework tube conveyor belt 6. During the rotation of the conveyor belt wheel 5, the firework tube conveyor belt 6 will also move. The arc-shaped limiting plate 15 mainly prevents the firework tube from detaching from the mounting base during the pressing process of the pressing mechanism 8, thus ensuring the pressing operation.

[0021] See Figure 6-9The fixed disk 80 is fixedly installed on the connecting shaft 7 and located above the rotating disk 3. The fixed disk 80 rotates with the connecting shaft 7. Multiple mounting slots 81 are opened on the outer edge of the fixed disk 80. Each mounting slot 81 is fitted with a limiting sleeve 82, which provides support. The limiting sleeve 82 is also movably fitted with a telescopic component 83. A first spring 84 is also fixedly fitted inside the limiting sleeve 82. A telescopic tube 85 is also installed on the upper part of the limiting sleeve 82, and the first spring 84 is partially located inside the telescopic tube 85.

[0022] See Figure 6-9 The telescopic assembly 83 includes a top rod 830, which is fitted inside a limiting sleeve 82, and a first spring 84 is also fitted on the top rod 830. A pressure wheel 831 is rotatably mounted on the top of the top rod 830, and a circular hole 832 is opened at the bottom of the top rod 830. A second spring 833 is fixedly installed in the circular hole 832, and a pressure column 834 is fixedly connected to the bottom of the second spring 833. The pressure column 834 is used to press the filler inside the firework tube.

[0023] The top rod 830 also has a first straight slot 16 in the middle, and the limiting sleeve 82 is also fixedly provided with a first limiting shaft 17, which also passes through the first straight slot 16. The pressing column 834 also has a second straight slot 18, and the top rod 830 is also provided with a second limiting shaft 19, which is located below the first straight slot 16.

[0024] Compressing principle: See Figure 3 and Figure 8 As the fixed plate 80 rotates, the top of each telescopic component 83 gradually contacts the gradient slope 12 at the bottom of the guide rail 11. During this process, the limiting sleeve 82 is always fixedly mounted in the mounting slot 81, ensuring that the limiting sleeve 82 will not move down. The specific process is as follows: First, as the pressing wheel 831 rotates, the pressing wheel 831 is compressed by the gradient slope 12, causing the top rod 830 to gradually descend. During the descent of the top rod 830, the first spring 84 is compressed first. The bottom of the first spring 84 is located on the protrusion inside the limiting sleeve 82, and the top rod 830 will drive the bottom pressing column 834 to gradually compact the material in the firework tube. The first limiting shaft 17 also passes through the first straight slot 16. The length of the first straight slot 16 determines the displacement range of the top rod 830. The first limiting shaft 17 can prevent the top rod from descending indefinitely or rebounding. The second spring 833 determines the compaction force, and the second straight slot 18 can determine the range of motion of the pressing column 834.

[0025] See Figure 2-4The support frame 1 is also fixedly equipped with a stabilizing plate 20. The stabilizing plate 20 is mainly used to stabilize the transmission fluctuation of the firework tube conveyor belt 6, and can avoid problems such as unstable compaction caused by vibration and other factors during the conveying process. The stabilizing plate 20 has a T-shaped groove 21. Pulleys 22 are symmetrically arranged inside the T-shaped groove 21. The pulleys 22 contact the upper and lower end faces of the firework tube conveyor belt 6 that pass through the T-shaped groove 21. The T-shaped groove 21 is open, so the firework tube will pass through the opening of the T-shaped groove without affecting the firework tube. The stabilizing plate 20 only works on the firework tube conveyor belt 6.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
