Description

Technical Field

[0001] This utility model relates to the field of fireworks production, and in particular to an automatic quantitative paraffin sealing device. Background Technology

[0002] Paraffin sealing is a common method for sealing fireworks. It is mainly used to seal the opening of fireworks to prevent the leakage of gunpowder and other raw materials, and to enhance the waterproof performance of fireworks.

[0003] Existing paraffin wax sealing devices for fireworks work by evenly adding molten paraffin wax to the parts of the fireworks that need sealing, ensuring a tight, gapless seal. After the paraffin wax cools, a strong seal is formed, effectively sealing the fireworks. Using this type of device to seal fireworks can improve the quality and safety of the products. Through strict sealing operations, it can ensure that the fireworks maintain a good effect during the firing process, while reducing safety risks. However, when the existing device injects paraffin wax, because the molten paraffin wax is in a fluid state, some excess paraffin wax will drip onto the fireworks or the work area when the device is called to add more. After cooling, it is difficult to clean, affecting the overall cleanliness of the work area. Regular cleaning is inconvenient, and the subsequent maintenance cost of the device is high.

[0004] Therefore, an automatic quantitative paraffin sealing device was developed to avoid excessive paraffin dripping and contaminating the working environment, and to improve the orderliness and cleanliness of paraffin sealing operations for fireworks. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides an automatic quantitative paraffin sealing device that can avoid excess paraffin dripping and polluting the working environment, and improve the orderliness and cleanliness of paraffin sealing operations for fireworks.

[0006] The technical solution of this utility model is: an automatic quantitative paraffin sealing device, comprising a base frame, a conveyor belt, a rotating shaft, a support frame, a drive assembly, a slide rail, a slider, a feeding tray, a feeding pipe, a piston, and an electric push rod. Multiple rotating shafts are rotatably connected to the upper part of the base frame, and a conveyor belt is wound between the rotating shafts. A support frame is connected to the top of the base frame, and a drive assembly is connected to the top of the support frame. A slide rail is connected to the upper part of the support frame, and a slider is slidably connected to the slide rail. A feeding tray is connected to the bottom of the slider, and feeding pipes are connected to the upper left and right sides of the feeding tray. A piston is slidably connected inside the feeding tray, and an electric push rod is connected to the upper part of the slider. The telescopic end of the electric push rod is connected to the piston.

[0007] Furthermore, it also includes a joystick, which is connected to the right side of the front pivot.

[0008] Furthermore, it also includes a scraper, which is provided on the upper rear side of the base frame and contacts the surface of the conveyor belt.

[0009] Furthermore, it also includes a collection box, which is placed on the upper rear of the base frame.

[0010] Furthermore, it also includes a limit frame, with the lower part of the support frame slidably connected to the limit frame.

[0011] Furthermore, the drive assembly includes a motor and a lead screw. The motor is connected to the top of the support frame, and the lead screw is connected to the motor output shaft. The slider is threadedly connected to the lead screw.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention controls the piston to move upward by an electric push rod. The upward movement of the piston creates a negative pressure in the feeding tray, which sucks the excess paraffin into the feeding tray. This can prevent excess paraffin from dripping and polluting the working environment, and improve the orderliness and cleanliness of the paraffin sealing operation for fireworks.

[0013] 2. This utility model uses a rocker arm to rotate a rotating shaft, which in turn causes the conveyor belt to run. The running of the conveyor belt, in conjunction with a scraper, removes and cleans the yellow mud generated by the placement of fireworks on the surface, ensuring the cleanliness of the conveyor belt and facilitating the cleaning of the yellow mud on the conveyor belt.

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] An automatic, metering paraffin sealing device, such as Figures 1-8 As shown, the device includes a base frame 1, a conveyor belt 2, a rotating shaft 3, a support frame 7, a drive assembly 9, a slide rail 10, a slider 11, a loading tray 12, a feeding pipe 13, a piston 14, and an electric push rod 15. Multiple rotating shafts 3 are rotatably connected to the upper part of the base frame 1, and the conveyor belt 2 is wound between the rotating shafts 3. The support frame 7 is connected to the top of the base frame 1, and the drive assembly 9 is connected to the top of the support frame 7. The slide rail 10 is connected to the upper part of the support frame 7, and the slider 11 is slidably connected to the slide rail 10. The loading tray 12 is connected to the bottom of the slider 11, and the feeding pipes 13 are connected to the upper sides of both the left and right sides of the loading tray 12. The piston 14 is slidably connected inside the loading tray 12. The electric push rod 15 is connected to the upper part of the slider 11, and the telescopic end of the electric push rod 15 is connected to the piston 14. The firework is placed on the conveyor belt 2 directly below the loading tray 12. The feeding pipe 13 is connected to the paraffin wax conveying equipment. Paraffin wax is added to the upper feeding tray 12. The drive component 9 controls the slider 11 to move downward. The downward movement of the slider 11 drives the upper feeding tray 12 to move downward. The upper feeding tray 12 moves downward and approaches the sealing position of the firework. Then, paraffin wax is injected into the sealing position of the firework. After the injection is completed, the electric push rod 15 controls the piston 14 to move upward. The upward movement of the piston 14 creates a negative pressure in the upper feeding tray 12, which sucks the excess paraffin wax into the upper feeding tray 12 to avoid the excess paraffin wax dripping and polluting the working environment. After the sealing is completed, the drive component 9 controls the slider 11 to reset upward. The upward reset of the slider 11 drives the upper feeding tray 12 to reset upward. Then, the sealed firework is removed, completing one paraffin wax sealing operation. The above operation can be repeated to repeat the paraffin wax sealing operation.

[0025] It also includes a rocker arm 4. The right side of the front rotating shaft 3 is connected to the rocker arm 4. The rotation of the rocker arm 4 drives the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 causes the conveyor belt 2 to run. The running of the conveyor belt 2 can adjust the position of the fireworks placed above.

[0026] It also includes a scraper 5. The scraper 5 is provided on the upper rear side of the base frame 1. The scraper 5 contacts the surface of the conveyor belt 2. The operation of the conveyor belt 2, in conjunction with the scraper 5, scrapes and cleans the yellow mud generated by the placement of fireworks on the surface, ensuring the cleanliness of the conveyor belt 2 and facilitating the cleaning of the yellow mud on the conveyor belt 2.

[0027] It also includes a collection frame 6. The collection frame 6 is placed on the upper part of the base frame 1. The yellow mud scraped off by the scraper 5 falls into the collection frame 6 for collection. The collection frame 6 is cleaned regularly to facilitate the centralized treatment of the cleaned yellow mud.

[0028] It also includes a limiting frame 8, with the lower part of the support frame 7 slidably connected to the limiting frame 8. The limiting frame 8 is used to restrict the position of the firework, ensuring that the position of the firework can move below the feeding tray 12, and to limit and protect the firework.

[0029] The drive assembly 9 includes a motor and a lead screw. The motor is connected to the top of the support frame 7, and the lead screw is connected to the output shaft of the motor. The slider 11 is threadedly connected to the lead screw. The rotation of the motor output shaft drives the lead screw to rotate, and the rotation of the lead screw drives the slider 11 to move up and down.

[0030] In use, the fireworks are first placed on the conveyor belt 2. The conveyor belt 2 is controlled by rotating the rocker arm 4. The rotation of the rocker arm 4 drives the rotating shaft 3 to rotate, which in turn moves the conveyor belt 2. The movement of the conveyor belt 2 allows for adjustment of the position of the fireworks. During adjustment, the limiting frame 8 restricts the position of the fireworks, ensuring they can move below the loading tray 12 and providing limiting protection. After the fireworks position is set, the feeding pipe 13 connects to the paraffin wax conveying equipment, adding paraffin wax into the loading tray 12. The drive component 9 controls the slider 11 to move downwards, causing the loading tray 12 to move downwards. The loading tray 12 moves downwards towards the sealing position of the fireworks, where paraffin wax is then injected. After injection... The electric push rod 15 controls the piston 14 to move upward. The upward movement of the piston 14 creates a negative pressure in the feeding tray 12, drawing excess paraffin wax into the feeding tray 12 and preventing excess paraffin wax from dripping and contaminating the working environment. After sealing, the drive component 9 controls the slider 11 to reset upward. The slider 11 resets upward, causing the feeding tray 12 to reset upward. Then, the sealed fireworks are removed, completing one paraffin wax sealing operation. The above operation can be repeated to repeat the paraffin wax sealing operation. The conveyor belt 2 runs in conjunction with the scraper 5 to scrape and clean the yellow mud generated on the surface of the fireworks, ensuring the cleanliness of the conveyor belt 2 and facilitating the cleaning of the yellow mud on the conveyor belt 2. The yellow mud scraped off by the scraper 5 falls into the collection box 6 for collection. The collection box 6 is cleaned regularly to facilitate the centralized treatment of the cleaned yellow mud.
